1. 我国首个采用冷却塔的“华龙一号”核电站 1 号冷却塔第一对人字柱顺利浇筑完成

全文:

7月7日凌晨4时24分,由中国能建安徽电建二公司承建的山东招远核电项目1号冷却塔第一对人字柱正式浇筑完成,这也是中国核电领域首次采用人字柱结构,标志着冷却塔工程正式迈入上部结构施工阶段。

招远核电1号冷却塔共设计48对人字柱构件,单根构件直径2米、总长14.87米,采用C60W12F300高强度抗冻抗渗混凝土,单根混凝土浇筑方量约46.7立方米。该类大体积、超高强度斜向受力构件,在国内核电冷却塔施工中无成熟经验、无既定工艺可循,是项目建设过程中核心技术攻坚难题,全程需要从零探索、专项突破。

本次施工攻坚主要攻克两大行业技术痛点,依托自主创新工艺实现施工质效双升。一是破解大尺寸钢筋笼吊装变形、定位不准难题。项目人字柱钢筋笼总长近15米,传统吊装工艺极易因受力不均衡产生骨架变形,且角度校准、就位定位完全依赖人工经验。为彻底解决这一问题,项目技术团队经过多轮方案论证、模拟推演和现场试验,自主研发专用吊装夹具,配套优化可调节滑轮组吊具,构建成套专属吊装工装体系。该套创新工装可实现钢筋笼起吊、空中翻转、角度微调、精准就位全流程一体化可控,完美完成钢筋笼从水平平躺、垂直站立到精准对位入座的全过程作业,彻底消除吊装安全隐患,百分百保障钢筋笼骨架结构完整性与安装精度。

二是攻克斜向构件混凝土振捣不密实的行业通病。人字柱为倾斜式建筑结构,常规振捣设备无法垂直插入作业,极易出现振捣不到位、混凝土疏密不均的问题。项目团队创新施工思路,采用钢丝绳布设振捣棒固定轨道,沿人字柱结构轴线精准预设振捣点位与作业路径,通过轨道标准化管控振捣棒插入深度、移动速度和提升轨迹,实现混凝土分层浇筑、分层振捣、逐层密实。这项简约高效的工艺创新,针对性解决了斜向高强混凝土构件振捣盲区问题,保障混凝土浇筑整体均匀密实,大幅提升构件成型质量。

招远核电项目作为国家"十四五"能源重点工程,对优化山东区域能源结构、助力全国"双碳"目标落地具有重要战略意义。本次人字柱成功浇筑,是中国能建安徽电建二公司在核电冷却塔领域的又一标志性突破,继世界首座超大型高位集水海水冷却塔——广东廉江核电项目之后,再次刷新国内核电异形结构施工技术突破。

下一步,项目团队将持续践行"精益即增效"的建设理念,依托数智化施工工艺、全流程精细化质量安全管控,全力打造标杆级核电精品工程,坚持以高质量党建引领工程高质量建设,持续攻坚克难、创新突破,为我国核电工程建设高质量发展注入强劲能建力量。

  • 值得关注的原因:招远核电为"华龙一号"新基地,冷却塔人字柱结构是常规岛关键节点,体现国内核电建设工艺迭代,也是核电冷却塔施工技术的重要突破。

18. 不营造“零事件”完美假象,我国以信息公开推动核安全业绩良性循环

全文:

核安全信息公开是《中华人民共和国核安全法》确立的法定制度,是我国现代核安全治理的重要组成部分,也是践行理性、协调、并进核安全观、保障公众合法权益的关键举措。我国始终坚持以公开促规范、以透明保安全、以公信稳发展,推动核安全治理由单向监管向多元共治转变,持续提升核安全治理的规范化、透明化、现代化水平。

核安全信息公开兼具民生保障、行业规范、国家治理三重价值。民生层面,坚持以人民为中心,主动公开核安全与辐射环境权威信息,精准回应公众关切,切实保障群众生命健康与知情权。行业层面,常态化公开形成刚性约束,倒逼核电运营单位压实安全主体责任,规范运行管理。国家治理层面,透明化的核安全治理能够凝聚社会共识、消除认知偏差,充分展现了我国严守核安全底线的坚定态度,持续提升核能领域国际公信力。

依据《中华人民共和国核安全法》《核安全信息公开办法》等法律法规,我国确立了客观、及时、准确、审慎的信息公开法定原则。一是依法公开、权责明晰。厘清国家核安全局监管职责与核设施营运单位主体责任,统一公开标准、范围与时限,实现公开工作法治化运行。二是客观真实、准确完整。如实公开核设施运行、辐射环境监测、安全执法、应急保障等核心信息,确保内容真实完备。三是及时高效、便民易懂。常态化发布常规信息,快速回应社会热点,兼顾专业性与通俗性,降低公众获取信息门槛。四是审慎有序、严守底线。严格落实保密规定,在合规前提下实现核安全信息最大化公开。

运行事件的全面公开,是中国核安全信息公开最具说服力的实践。核电运行期间,反应堆保护系统会因监测到参数微小偏离或出于预防性安全考虑而触发自动或手动停堆,国际业界规范称之为"非计划停堆"。根据国际通行的科学认知,此类停堆绝大多数属于"无安全意义"的0级事件,是纵深防御系统正常响应、安全功能成功触发的证明。世界核电运营者协会(WANO)将单台机组年均非计划自动停堆次数作为衡量机组运行可靠性的核心指标,行业比较认可的卓越值约为0.20次/堆·年。我国全面对标这套国际标准,完整记录、主动公开相关运行事件。据国家能源局《2024年全国电力可靠性年度报告》,2020年—2024年国内在运机组平均非计划停堆频次为0.15次/堆·年,优于这一先进目标,机组运行稳定性能达到国际一流水平。

从核安全文化视角审视,高密度的事件报告恰恰折射出高度成熟的"报告文化"。世界核电发展经验表明,运行事件报告机制完善、主动坦诚上报的国家,普遍具备深厚的核安全文化和完备的经验反馈体系。我国坚持核电全生命周期从严管控,对建造质量偏差、调试参数异常、运行设备事件全部留痕建档、闭环整改、溯源管理,将"安全第一、质量第一"的方针转化为可追溯、可监督、可改进的制度化治理实践。

中国核安全监管的有效性已得到国际原子能机构的权威确认。应中国政府邀请,2010年、2016年和2025年,国际原子能机构先后3次对我国开展核安全综合评估,历次结论均高度认可中国核安全监管体系的有效性和透明度,特别肯定中国将核安全置于最高优先地位的政治承诺。2026年4月在维也纳举办的《核安全公约》第十次审议会上,我国4项监管实践获87个缔约方认可,取得历史最佳成绩,彰显透明履约、引领全球核安全治理的大国担当。

我国核安全信息公开与核安全业绩形成了良性互促的正向循环。常态化的事件发布和专家解读,让公众看到核电安全风险的极低概率和可控状态,社会接受度显著提高,有效支撑了我国核电在运在建规模世界第一的社会舆论氛围。透明的安全数据推动全产业链不断优化设计、制造和运维水平,形成了"发现偏差—公开分析—系统纠正—验证闭合"的持续改进机制。

核安全信息的公开,目的从来不是营造"零事件"的虚假完美表象,而是以坦诚透明的文化构筑"零容忍"的真实安全根基。展望未来,中国将继续以国际最高标准为参照,深化核安全信息公开,强化经验反馈与体系运行,以经得起任何审视的透明实践,为公众注入持久信心,为全球核安全治理贡献中国方案。

  • 值得关注的原因:核安全文化从"零事件"叙事转向透明公开,是国内监管理念重要进步。

20. 韩国核能学会建议在第十二次电力规划中扩大核电和 SMR 建设

全文:

韩国核能学会7月8日发布《三大大型项目稳定电力供应政策建议》,呼吁韩国政府在正在制定的第十二次电力供需基本规划中,更积极地反映新建大型核电站和小型模块化反应堆(SMR)的建设方案,以支撑半导体产业集群、人工智能数据中心和物理人工智能等三大大型项目的用电需求。

韩国政府上月底将半导体产业集群、人工智能数据中心和物理人工智能列为三大大型项目。韩国核能学会认为,这些项目能否顺利推进,稳定、经济的无碳电力供应是关键。尤其是半导体工厂和人工智能数据中心用电强度高,对供电连续性和电能质量要求严格,需要全年365天、每天24小时不间断运行。学会表示,核电能够提供大规模、稳定的无碳电力,是高耗能高科技产业的重要电源选择。

根据学会引用的需求预测,到2035年,龙仁半导体产业集群用电需求约为15吉瓦,西南半导体产业园区约为6.3吉瓦,人工智能数据中心约为18.4吉瓦。即使不计算已纳入现有规划的龙仁产业集群,仅西南半导体产业园区和人工智能数据中心带来的新增发电容量需求就达到24.7吉瓦。按韩国最新大型核电机组APR1400单机容量1.4吉瓦计算,这相当于约18台机组的供电能力。

韩国核能学会指出,政府已在第十一次电力供需基本规划中反映了两座新核电站和一座SMR建设计划,但三大大型项目带来的额外用电需求可能明显超过现有供电安排。学会建议,第十二次电力供需基本规划应基于政府公布的产业需求预测和现有电力供应计划,重新测算供需缺口,并明确大型核电站和SMR的追加建设路径,包括建设规模、选址和推进时间表。

除电源建设外,学会还把电网列为需要尽快解决的关键问题。其解释称,核电站作为国家核心基础设施,从选址、许可审批到建设完成,通常需要10年以上。如果等到规划最终确定后才启动选址,可能难以匹配高科技产业投产节奏。因此,应结合电力需求中心分布和电网条件,提前开展新建核电站的区域调查和候选厂址研究。

学会同时提醒,即便电站按期建成,如果输电线路和变电站建设滞后,电力仍难以及时送达需求中心。为此,学会建议建立相应制度,将输电线路和变电站指定为国家战略设施,整合并加快目前分散在不同部门的许可审批程序,同时为沿线居民建立合理补偿机制。

韩国核能学会表示,高科技产业的运行不能只依靠规划和声明,政府有必要用客观数据重新检视产业战略与电力供应计划之间是否匹配,并尽快提出扩大无碳基荷电源的具体方案。

  • 值得关注的原因:韩国核电政策转向扩张,SMR被纳入国家电力规划,区域竞争加剧。

21. 美国 NRC 拟大幅修订环境审查规则,推动新核能项目许可提速

全文:

美国核管理委员会(NRC)7月8日表示,计划对其环境审查法规进行数十年来最全面的一次修订,以推动核能项目许可审批流程更加聚焦、高效和可预测。

根据NRC发布的信息,这项改革将把环境审查范围限定在该机构法定职权所能处理的影响之内。换句话说,审查重点将更集中在NRC有权评估和采取监管行动的事项上。NRC认为,这样既有助于维持环境保护要求,也能为新核能项目提供更多简化审批的机会。

提案还扩大了"类别豁免"的适用范围,涵盖某些特定行动,其中包括部分新反应堆项目。NRC表示,这类行动通常不会造成重大环境影响,因此可适用更简化的环境审查安排。

NRC主席Ho K. Nieh表示,该提案将使环境审查工作更专注于关键问题。通过聚焦NRC有权处理的影响因素,机构既能加强环境保护,也能提升许可审查的及时性和可预测性。

NRC称,这一提案与其近期完成的新反应堆类别豁免及通用环境评估相关法规相衔接,标志着环境监管框架的一次重要现代化调整。相关举措将共同形成一个更具针对性、更高效的审查体系,用于未来核能项目许可,同时继续满足《国家环境政策法》的要求,并履行NRC在环境保护方面的职责。

该提案落实了近期法律修订内容,也反映了近期法院判决精神,并推进第14300号行政命令提出的监管现代化目标。NRC将就该提案征求公众意见至8月21日,并计划在意见征询期间召开公众会议。

  • 值得关注的原因:美国核能许可流程系统性松绑,是全球核电复兴政策风向标(详见国际媒体章节)。

22. 俄罗斯国家原子能公司提前完成吉尔吉斯斯坦两处核废料库修复工程

全文:

近日,俄罗斯国家原子能公司(Rosatom)总经理阿列克谢·利哈乔夫表示,集团已提前完成吉尔吉斯斯坦两处核生产废料储存设施的复垦修复工作。此次涉及的设施为塔穆云和克孜勒-贾尔两处尾矿库,相关工程原本属于吉尔吉斯斯坦核遗产治理的重要组成部分。

利哈乔夫指出,俄罗斯原子能集团在吉尔吉斯斯坦的工作重点首先集中在生态项目上。苏联时期遗留下来的核工业尾矿库长期被视为地区环境安全隐患,如何将这些设施恢复到可接受状态,是俄方参与当地合作项目的重要责任之一。

据介绍,吉尔吉斯斯坦境内共有三处此类重点尾矿库。除已经提前完成修复的塔穆云和克孜勒-贾尔外,卡吉-赛尾矿库由于废料积存规模更大,后续治理任务更重。俄罗斯原子能集团表示,将在该项目上尽可能快速、高效地推进工作。

除核废料治理外,俄吉双方还在讨论核能合作的新方向。利哈乔夫透露,吉尔吉斯斯坦政府已收到一项关于建设小功率核电站的提议,该项目拟基于"Ритм"系列反应堆技术。相关议题预计将在叶卡捷琳堡举行的"创新工业展"期间,由俄罗斯和吉尔吉斯斯坦两国总理接触时进一步讨论。

25. 通用聚变与 Spring Valley 合并获股东批准,拟登陆纳斯达克

全文:

7月6日,Spring Valley Acquisition Corp. III宣布,其股东已批准此前公布的与加拿大聚变能源企业General Fusion Inc.的业务合并。General Fusion的证券持有人也在同日举行的特别会议上投票批准了该交易。

根据安排,这笔交易预计将在2026年7月10日左右完成,前提是获得监管批准,并满足或豁免相关交割条件。交易完成后,Spring Valley将更名为"General Fusion Group Ltd."。合并后公司的股票和认股权证预计随后在纳斯达克上市交易,股票代码分别为"GFUZ"和"GFUZW",但仍需相关上市申请获得批准。

General Fusion总部位于加拿大温哥华,成立于2002年,主要推进磁化靶聚变技术商业化。该公司认为,这一路线有望以具有成本竞争力的方式提供零碳基础负荷电力。与依赖超导磁体或高功率激光器的部分聚变方案不同,General Fusion的磁化靶聚变技术试图采用更偏工程化的路径,利用现有材料制造耐用设备,并通过机械方式压缩等离子体。

General Fusion首席执行官格雷格·特温尼表示,交易预计完成是公司发展历程中的重要节点。他认为,在当前阶段将聚变技术引入资本市场,并成为上市的纯聚变公司,对公司继续推进商业化、实现向电网输送清洁聚变能源的目标具有重要意义。

Spring Valley董事长兼首席执行官克里斯·索雷尔斯表示,全球电力需求正在增长,市场对可靠、清洁能源的需求也在上升。他认为,General Fusion凭借管理团队、同行评审成果、专利组合以及正在运行的LM26聚变示范装置形成了自身特点。

2025年初,General Fusion宣布其"劳森26号机"(LM26)聚变示范装置已完成设计、建造并投入运行,整个过程用时不到两年。公司称,LM26是首个达到商业化规模的磁化靶聚变示范装置。按照目前设计,LM26采用锂衬里机械压缩等离子体,压缩后的等离子体直径达到商业规模的50%。

LM26的目标是逐步实现若干关键聚变技术里程碑,包括将等离子体加热至1keV(约1000万摄氏度);随后提升至10keV(约1亿摄氏度);最终达到劳森判据相关要求,也就是在等离子体中产生净聚变能量所需的一组聚变参数条件。

Spring Valley所属投资集团长期关注电力基础设施和脱碳领域企业。过去五年,该集团旗下投资机构通过四次首次公开募股募集了9.2亿美元。此前,Spring Valley I完成了与美国小型模块化反应堆技术公司NuScale Power Corporation的业务合并;Spring Valley II完成了与Eagle Nuclear Energy Corp.的业务合并,后者是一家拥有美国大型露天约束型铀矿床开采权的下一代核能公司。

二、国际核组织与监管机构(IAEA / NRC / ONR / OECD-NEA)

31. IAEA 发布第 357 号总干事关于乌克兰局势声明(Update 357)

英文全文:

9 July 2026, Vienna, Austria — IAEA teams based at nuclear power plants in Ukraine have heard sounds of military activity several times in recent days, including drones and gunfire, Director General Rafael Mariano Grossi said today.

The reports highlight the persistent risks to nuclear safety and security during the ongoing conflict, underlining the challenging conditions facing these sites and the importance of continuing efforts by the IAEA to help prevent an accident. There were no reports of damage to the plants.

The IAEA team at the Khmelnytskyy Nuclear Power Plant (KhNPP) heard military aircraft early on 8 July, and was later informed that drones were detected north of the site. The South Ukraine NPP (SUNPP) reported the detection of six drones early on 5 July and three drones on 2 July. At the Zaporizhzhya Nuclear Power Plant (ZNPP), the IAEA team heard gunfire on 6 July followed by the sound of a drone flying overhead while they were outside. The team immediately moved indoors.

In another reported incident, the IAEA was informed by the Russian Federation that a drone on 5 July hit and damaged a cooling tower of a power unit under construction at the Kursk NPP-2.

"These incidents show that the nuclear safety and security situation remains fragile during the war, with military activity continuing to take place near major nuclear facilities," Director General Grossi said. "I once again call for maximum military restraint around nuclear sites and for full respect of the Seven Indispensable Pillars and the Five Concrete Principles for protecting the ZNPP."

Separately, the ZNPP on 3 July temporarily lost all off-site power for the 21st time since the start of the conflict. The plant told the IAEA team that the 330 kV Ferosplavna-1 line was quickly restored, but that two lines connecting it to the site had disconnected after protection systems were activated, extending the duration of the ZNPP's loss of off-site power. The site reported no physical damage to those lines.

All available emergency diesel generators started automatically to provide the electricity needed for essential safety functions. The site later recovered the connection to Ferosplavna-1 through the recently restored 330 kV ZNPP back-up transformer line, and the last emergency diesel generator was stopped about two hours after the event began. The second transmission line connecting the ZNPP to the Ferosplavna-1 line also resumed approximately one hour later. The cause of the latest loss of off-site power was not yet known.

The ZNPP's main 750 kV Dniprovska power line remains unavailable despite recent repairs, following damage in May to an associated electrical substation located more than 100 kilometres northwest of the plant.

"A loss of off-site power, even if brief, is always a serious concern for nuclear safety," Director General Grossi said. "Reliable external power is needed to maintain the operation of essential safety systems. Repeated power losses show why this situation is not sustainable."

The IAEA also continued its nuclear safety and security assistance to Ukraine. The Agency delivered an electric water heater with a voltage stabilizer to the State Nuclear Regulatory Inspectorate of Ukraine, made possible with funds from the United States.

Since the beginning of the armed conflict, the IAEA has completed more than 240 deliveries in response to emergency requests from nearly 50 entities across Ukraine.

2026年7月9日,奥地利维也纳——国际原子能机构总干事拉斐尔·马里亚诺·格罗西今天表示,驻扎在乌克兰各核电站的IAEA小组近日多次听到军事活动声响,包括无人机和枪声。

这些报告凸显了持续冲突中核安全与核安保所面临的长期风险,凸显了这些场址所处的艰难条件,以及IAEA持续努力防止事故发生的重要性。没有报告称电厂受损。

驻扎在赫梅利尼茨基核电站(KhNPP)的IAEA小组于7月8日清晨听到军用飞机声音,随后被告知在场址以北探测到无人机。南乌克兰核电站(SUNPP)报告7月5日清晨探测到6架无人机、7月2日探测到3架无人机。在扎波罗热核电站(ZNPP),IAEA小组7月6日听到枪声,随后在户外时听到一架无人机从上空飞过的声音,小组立即转移至室内。

在另一报告事件中,俄罗斯联邦告知IAEA,7月5日一架无人机击中并损坏了库尔斯克二期(Kursk NPP-2)在建机组的一座冷却塔。

格罗西总干事表示:"这些事件表明,战时核安全与核安保局势依然脆弱,主要核设施附近仍持续发生军事活动。我再次呼吁在核设施周边保持最大限度的军事克制,并充分尊重确保武装冲突中核安全与核安保的'七项 indispensable 支柱'以及保护扎波罗热核电站的'五项具体原则'。"

此外,扎波罗热核电站于7月3日临时丧失全部场外电源,这是冲突开始以来的第21次。电站告知IAEA小组,330千伏Ferosplavna-1线路很快恢复,但连接电站的两条线路在保护系统启动后断开,延长了丧失场外电源的时长。场址报告这些线路未发生物理损坏。

所有可用的应急柴油发电机自动启动,为必要安全功能提供所需电力。随后电站通过近期恢复的330千伏ZNPP备用变压器线路恢复了与Ferosplavna-1的连接,最后一台应急柴油发电机在事件开始后约两小时停止。连接ZNPP与Ferosplavna-1的第二条输电线路也约一小时后恢复。最新一次丧失场外电源的原因尚不清楚。

尽管近期进行了维修,ZNPP主750千伏第聂伯罗夫斯卡(Dniprovska)电力线仍然不可用,此前5月该线路相关、位于电站西北100多公里外的变电站受损。

格罗西总干事表示:"丧失场外电源,即使很短暂,也始终是核安全的严重关切。维持必要安全系统的运行需要可靠的外部电源。反复断电表明这一局势不可持续。"

IAEA还继续向乌克兰提供核安全与核安保援助。在美国资金支持下,机构向乌克兰国家核监管监察局交付了一台带稳压器的电热水器。

自武装冲突开始以来,IAEA已响应乌克兰近50家机构的紧急请求,完成了240多批次物资交付。

  • 值得关注的原因:战时核安全是IAEA最高优先级议题,扎波罗热反复断电与无人机袭扰设施凸显核事故风险,声明影响国际核保障与援助部署。

32. IAEA 与世界银行集团合作推进核能促发展

英文全文(节选):

One year ago, the IAEA and the World Bank Group (WBG) signed a partnership agreement to support the safe, secure and responsible use of nuclear power for development. This landmark agreement marked the WBG's formal reengagement with nuclear power after a decades-long pause, signalling a broader shift that other international financial institutions have begun to follow.

The IAEA and the WBG agreed to work together in three key areas: building nuclear knowledge within the WBG to support decision making on nuclear financing; supporting the long-term operation of existing nuclear power plants; accelerating the development of small modular reactors (SMRs).

According to the World Bank Group, emerging economies will account for almost two-thirds of global electricity needs by 2035. To meet this growing demand, annual investment in power generation in developing countries must more than double, from $280 billion today to $630 billion. As of 1 June 2026, 415 reactors were in operation worldwide, providing 379.0 GW(e) of nuclear capacity. In the high case projection, the IAEA estimates that global nuclear operational capacity will more than double by 2050 — with SMRs expected to play a pivotal role.

In the year since, IAEA Director General Grossi has briefed senior officials from the WBG and other multilateral development banks; the IAEA held informational sessions for WBG staff; several technical meetings were convened on long term operation safety and financing assessment. In January, the IAEA hosted a workshop in Vienna on expanding cooperation to other international financial institutions, exploring how such organizations might finance the technical groundwork needed before nuclear investment decisions — feasibility studies for SMRs, early-stage infrastructure development, radioactive waste disposal planning and stakeholder engagement.

中文翻译:

一年前,IAEA与世界银行集团(WBG)签署合作协议,支持以安全、可靠、负责任的方式利用核能促进发展。这一标志性协议标志着世界银行在暂停数十年后正式重返核能领域,也释放出其他国际金融机构开始跟进的更广泛信号。

IAEA与世界银行同意在三个关键领域合作:在世界银行内部建设核知识以支撑核能融资决策;支持现有核电站的长期运行;加速小型模块化反应堆(SMR)的开发。

据世界银行集团,到2035年新兴经济体将占全球电力需求的近三分之二。为满足增长需求,发展中国家的发电年投资必须翻倍以上,从目前的2800亿美元增至6300亿美元。截至2026年6月1日,全球在运反应堆415台,核电装机容量379.0 GW(e)。在高情景预测下,IAEA估计到2050年全球核电在运装机容量将翻倍以上——SMR预计将发挥关键作用。

一年来,格罗西总干事向WBG及其他多边开发银行高级官员通报情况;IAEA为WBG员工举办核电信息会;就长期运行安全与融资评估召开多次技术会议。1月,IAEA在维也纳举办研讨会,推动与其他国际金融机构的合作,探讨此类机构如何为核能投资决策前的工程技术基础工作提供融资——包括SMR可行性研究、早期基础设施建设、放射性废物处置规划及利益相关方参与。

36. ONR 发布 Sizewell B 延寿至 2055 声明

英文全文:

A spokesperson for the Office for Nuclear Regulation (ONR) said: "We regulate in an enabling manner, working constructively with EDF on their plans to extend the life of their nuclear plants by reviewing technical and safety case considerations while ensuring it achieves the required standards of safety and security in the most practical way.

"Although their plant life extension decisions do not need formal regulatory assessment or permissioning by ONR, it is a requirement of the site licence that operations be carried out under a valid safety case. Our regulatory activity evaluates the adequacy of both the safety case, the security plan and their implementation.

"Safety cases at Sizewell B are likely to require updating to achieve EDF's stated ambition, together with investment in plant to sustain equipment reliability, all while ensuring that the necessary people and skills are available throughout the extended lifetime. Security plans also require updating to ensure they remain robust and responsive to the evolving security landscape.

"The ongoing safety and security of operations at any nuclear site must be fully demonstrated to us as part of ongoing regulation which will be informed by our extensive, proportionate and targeted inspection and assessment regime."

中文翻译:

英国核监管办公室(ONR)发言人表示:"我们以'赋能式'方式实施监管,与EDF建设性地合作推进其核电站延寿计划,审查技术与安全论证考量,同时以最切实的方式确保其达到所要求的安全与安保标准。

"尽管其机组延寿决定无需ONR的正式监管评估或许可,但场址许可证要求运营必须在有效安全论证下进行。我们的监管活动会评估安全论证、安保计划及其实施的充分性。

"为达成EDF所述的雄心,Sizewell B的安全论证可能需要更新,并需对电站投资以维持设备可靠性,同时确保在整个延寿期内具备必要的人员与技能。安保计划也需更新,以确保其持续稳健并能应对不断演变的安全形势。

"任何核设施运营的持续安全与安保都必须向我们充分证明,这也是持续监管的一部分,我们将以广泛、适度且有针对性的检查与评估制度为依据。"

39. Sizewell B 获 20 年延寿,运行至 2055 年

英文全文:

The UK's Sizewell B nuclear power plant is set to get a 20-year lifetime extension after terms were agreed by the UK government and operator EDF. The pressurised water reactor, which came online in 1995, had an initial 40-year operating life to 2035. Following the agreement on financing, EDF will fund GBP800 million (USD1 billion) of refurbishment works to be carried out during planned outages over the next 15 years.

These works include installing a new environmental monitoring system and new automated plant monitoring systems, as well as replacing pipework, valves and pumps across the site.

The heads of terms for a contract for difference agreement includes a strike price of GBP70.50 per MWh for the period 2035 to 2055. That price is lower than the one agreed for Hinkley Point C, and below the current wholesale price.

EDF UK CEO Simone Rossi said: "Extending the life of the plants we already have alongside building new ones is central to EDF's strategy." UK Energy Secretary Ed Miliband said: "Nuclear power is vital for our energy security, and this extension will help produce the clean power our country needs."

The UK generates about 15% of its electricity from about 5.9 GWe of nuclear capacity, however most existing capacity is to be retired at the end of the decade. The UK is aiming for up to 24 GWe of new nuclear capacity by 2050 to provide about 25% of electricity.

Sizewell B is the UK's only pressurised water reactor and has more potential for life extensions than the Advanced Gas Cooled Reactor fleet. So far, Sizewell B has produced more than 270 terawatt-hours of electricity since 1995. About 900 people are employed at the plant.

Tom Greatrex, Chief Executive of the UK's Nuclear Industry Association, said: "Sizewell B is the cleanest, most productive and most reliable plant in the whole country, so extending its life is one of the best things we can do to build an affordable and reliable clean power system."

中文翻译:

在英国政府与运营商EDF达成协议后,英国Sizewell B核电站将获得20年延寿。这座1995年投运的压水堆初始运行寿命为40年至2035年。在融资协议达成后,EDF将在未来15年计划停堆大修期间投入8亿英镑(10亿美元)进行翻新工程。

工程包括安装新的环境监测系统与新自动化电站监控系统,并更换全厂管道、阀门与泵。

差价合约条款要点包含2035至2055年期间每兆瓦时70.50英镑的执行价。该价格低于为Hinkley Point C约定的价格,也低于当前批发价。

EDF英国CEO Simone Rossi表示:"在建设新机组的同时延长现有机组寿命,是EDF战略的核心。"英国能源大臣Ed Miliband表示:"核电对我们的能源安全至关重要,此次延寿将有助于生产国家所需的清洁电力。"

英国约15%的电力来自约5.9 GWe的核电装机,但现有装机大部分将在本十年末退役。英国目标到2050年新增至多24 GWe核电装机,提供约25%的电力。

Sizewell B是英国唯一的压水堆,比先进气冷堆(AGR)舰队更具延寿潜力。自1995年以来,Sizewell B已发电超过270太瓦时,电站雇佣约900人。

英国核能行业协会首席执行官Tom Greatrex表示:"Sizewell B是全国最清洁、最高效、最可靠的电站,因此延长其寿命是我们建设可负担、可靠清洁电力系统能做的最好举措之一。"

41. 澳大利亚同意向印度出口铀

英文全文:

India and Australia have signed the administrative arrangement to enable uranium exports to India for peaceful purposes under the nuclear cooperation agreement signed between the two countries more than a decade ago. The announcement came during an official visit by India's Prime Minister Narendra Modi to Australia.

"The arrangement facilitates Australian uranium exports to India to help increase the share of non-fossil fuel power capacity, providing an additional market for the Australian resources sector," the Australian government said.

India has an ambitious nuclear power programme but few indigenous uranium resources. Australia is the world's fourth-largest producer of uranium behind Kazakhstan, Canada and Namibia. All of its production is exported under strict controls to ensure civilian use only. Australia requires any countries to which it sells uranium to put in place a rigorous bilateral safeguards treaty.

While India has an impeccable nuclear non-proliferation record it is not a signatory of the NPT, and was effectively isolated from world nuclear trade until 2008, when it signed a safeguards agreement with the IAEA. The 45-member Nuclear Suppliers Group subsequently agreed to exempt the country from rules prohibiting trade with non-members of the NPT.

A bilateral agreement between Australia and India for the supply of uranium was signed in 2014, and came into force in November 2015. Australia and India have now finalised the administrative arrangements necessary to enable the export of Australian uranium to India for exclusively peaceful purposes and under IAEA safeguards.

Australian Prime Minister Anthony Albanese said: "Australia's natural resources are vital for other countries' energy security and stability, and we look forward to becoming a reliable, trusted supplier of uranium to India." Prime Minister Modi added: "This will open the way for uranium supplies from Australia to India and give new impetus to our clean energy objectives."

In March, Canada's Cameco entered a long-term agreement to supply uranium ore concentrate to India's Department of Atomic Energy, for use in the country's fleet of nuclear reactors. India currently has 24 operating reactors along with ambitious plans to deploy dozens more to reach 100 GW by 2047.

中文翻译:

印度与澳大利亚签署了行政安排,使澳大利亚能够在两国十多年前签署的核合作协议框架下,向印度出口用于和平目的的铀。该声明是在印度总理莫迪正式访澳期间宣布的。

澳大利亚政府表示:"该安排促进澳大利亚向印度出口铀,以帮助提高非化石能源发电容量占比,为澳大利亚资源行业提供额外市场。"

印度拥有雄心勃勃的核电计划但本土铀资源稀少。澳大利亚是世界第四大铀生产国,仅次于哈萨克斯坦、加拿大和纳米比亚。其全部产量在严格管控下出口,仅确保民用。澳大利亚要求任何购铀国都必须建立严格的双边保障条约。

尽管印度拥有无可挑剔的核不扩散记录,但它并非《不扩散核武器条约》(NPT)签署国,在2008年与IAEA签署保障协议前实际上被隔绝于世界核贸易之外。由45个成员组成的核供应国集团随后同意豁免该国,解除与NPT非成员国贸易的禁令。

澳大利亚与印度的铀供应双边协议于2014年签署,2015年11月生效。双方现已敲定必要行政安排,使澳大利亚铀能在IAEA保障下专用于和平目的出口印度。

澳大利亚总理阿尔巴尼斯表示:"澳大利亚的自然资源对其他国家的能源安全与稳定至关重要,我们期待成为印度可靠、可信赖的铀供应国。"莫迪总理补充道:"这将为澳大利亚向印度供应铀打开通道,并为我们清洁能源目标注入新动力。"

今年3月,加拿大Cameco与印度原子能部签署长期协议,向印度反应堆舰队供应铀精矿。印度目前在运反应堆24台,并雄心勃勃计划再部署数十台,到2047年实现100 GW。

43. World Bank 与 IAEA 合作满一周年(ANS 评述)

英文全文(节选):

The International Atomic Energy Agency and the World Bank Group (WBG) recently provided an update on their partnership's progress at the one-year mark. That partnership, entered into only weeks after the World Bank reversed its long-standing ban on nuclear power investment, aims to facilitate new financing and construction of advanced nuclear projects in developing countries.

WBG was founded in 1944 and issued its first and only loan to a nuclear power project in 1959: the Garigliano nuclear power station in Italy. No more loans for nuclear projects were issued in the ensuing decades, and the group formalized a ban on funding nuclear power in 2013.

WBG formally reversed course on its nuclear policy in June 2025. Weeks later, WBG and the IAEA entered into their partnership, which has three main areas of cooperation: expand the World Bank's technical expertise surrounding nuclear safety, safeguards, fuel cycles, regulatory frameworks, and waste management; support countries in extending the lifespans of existing nuclear reactors; expedite the deployment of SMRs and other advanced technologies in developing countries.

Since then, announcements have been few. In May, Reuters reported that WBG was in exploratory talks with Eskom, South Africa's state power utility, over a potential multibillion-dollar nuclear investment covering up to 5,200 megawatts of new capacity. The IAEA's new update highlights several collaborative actions: IAEA Director General Grossi briefed senior officials from WBG and other multilateral development banks; the IAEA held information sessions; several technical meetings were convened on long term operation safety and financing assessment. In January, the IAEA hosted a workshop in Vienna to get other multilateral development banks on board, where senior experts from WBG, the EBRD, the ADB, and the OPEC Fund discussed how their organizations might finance the technical groundwork needed before nuclear investment decisions.

国际原子能机构与世界银行集团(WBG)近期在其合作一周年之际更新了进展。该伙伴关系是世界银行推翻长期禁止核电投资政策仅数周后建立的,旨在为发展中国家新建先进核项目便利融资与建设。

世界银行成立于1944年,1959年向其唯一一笔核电项目贷款——意大利Garigliano核电站。此后数十年未再发放核电贷款,并于2013年正式确立禁止为核电融资。

世界银行于2025年6月正式扭转核电政策。数周后,WBG与IAEA建立伙伴关系,三大合作领域为:拓展世界银行围绕核安全、保障、燃料循环、监管框架与废物管理的专业技术;支持各国延长现有核反应堆寿命;加速SMR及其他先进技术在发展中国家的部署。

此后相关公告寥寥。5月,路透社报道WBG正与南非国有电力公司Eskom就潜在数十亿美元核电投资(覆盖至多5200兆瓦新装机)进行初步会谈。IAEA的新更新强调了若干协作行动:总干事格罗西向WBG及其他多边开发银行高官通报;IAEA举办信息会;就长期运行安全与融资评估召开技术会议。1月,IAEA在维也纳举办研讨会推动其他多边开发银行参与,WBG、欧洲复兴开发银行、亚洲开发银行及OPEC基金的专家探讨了各机构如何为核能投资决策前所需技术基础工作融资。

44. ANS 临界安全标准 ANS-8.22 草案公开征求意见

英文全文:

The American Nuclear Society recently opened a draft standard for public review. ANS-8.22-202x, Nuclear Criticality Safety Based on Limiting and Controlling Moderators, is a revision of ANS-8.22-1997 and provides criteria for limiting and controlling moderators in operations with fissile materials.

Until recently, announcements of public review opportunities for ANS standards have been published exclusively in ANSI's weekly ANSI Standards Actions. However, the Nuclear Regulatory Commission is currently working to expedite the standards endorsement process and therefore is seeking a greater amount of public review for nuclear-related standards. To that end, ANS has begun posting public review opportunities on the ANS standards website.

The 1997 version of ANS-8.22 was most recently reaffirmed in 2021. This criticality standard applies to those operations that depend on moderator control for maintaining subcritical conditions. The deadline for public comment is August 10.

此前,ANS标准的公众评审机会仅在ANSI每周《ANSI标准动态》上发布。但核管制委员会目前正努力加快标准认可流程,因此需要更多公众对核相关标准的评审。为此,ANS已开始在其标准网站上发布公众评审机会。

1997版ANS-8.22最近于2021年重新确认。该临界安全标准适用于依赖慢化剂控制维持次临界状态的操作。公众意见截止日期为8月10日。

  • 值得关注的原因:临界安全是燃料循环与先进堆设计底线,标准更新影响全行业合规。

46. 萨凡纳河遗址 H Canyon 设施试点新型风险分级维护方法

英文全文:

Savannah River Nuclear Solutions (SRNS) has implemented a pilot program that introduces a new approach to maintenance planning and control processes at the Savannah River Site. The program, initially used to support environmental management operations at the SRS H Canyon complex, is a "graded, risk-based approach that prioritizes urgency and aligns controls with three defined hazard levels [low, medium, and high]."

SRNS says the new maintenance pilot program at H Canyon is part of broad modernization and streamlining efforts begun in March to "accelerate non-nuclear, non-complex construction projects" while implementing OSHA+ safety standards. Maintenance activities at SRS have long been based on a one-size-fits-all work-control approach that applies uniform nuclear operation standards to every project, regardless of size or risk.

The new approach introduces fit-for-purpose work packages structured according to low, medium, or high risk. Low-risk jobs require only basic work package rigor; medium-risk jobs may need additional guidance; high-risk jobs require detailed instructions. After demonstration at H Canyon, similar initiatives are expected at other SRS facilities.

H Canyon is the "only operating, production-scale, radiologically-shielded chemical separations facility in the United States," begun in the early 1950s. Its mission changed post-Cold War to nonproliferation and environmental cleanup. Uranium recovery operations restarted in February; HB Line operations restarted in March to recycle surplus plutonium and produce MOX fuel for advanced reactors.

中文翻译:

萨凡纳河核方案公司(SRNS)实施了一项试点计划,在萨凡纳河遗址引入维护规划与控制流程的新方法。该计划最初用于支持SRS H Canyon综合体的环境管理运营,是一种"分级、基于风险的方法,优先处理紧急事项,并将管控与低、中、高三个既定危害等级对齐"。

SRNS表示,H Canyon的新维护试点是其3月启动的广泛现代化与精简工作的一部分,旨在"加速非核、非复杂建设项目"并落实OSHA+安全标准。SRS的维护活动长期基于"一刀切"的工作控制方法,无论项目规模或风险如何,都套用统一的核运营标准。

新方法引入"量身定制的工作包",按低、中、高风险分级。低风险作业仅需基本工作包严格度;中风险可能需额外指导;高风险需详细指令。在H Canyon示范后,类似举措预计将在SRS其他设施推行。

H Canyon是"美国唯一在运的、生产规模的、带放射屏蔽的化学分离设施",始于1950年代初。冷战后其使命转向不扩散与环境清理。铀回收作业2月重启;HB Line作业3月重启,以回收过剩钚并为先进反应堆生产MOX燃料。

47. 无人机袭击库尔斯克二期(Kursk-II)冷却塔

英文全文:

A drone strike has hit the cooling tower designated for unit 2 of the Kursk-II NPP in Kurchatov. Regional governor Alexander Khinshtein reported the strike, noting that because this specific section is still under development, the cooling tower system has not yet been put into operation. There have been no reported injuries, structural failures, or negative environmental or radiological consequences. Russian air defence detected and neutralised 12 UAVs heading toward Kurchatov.

Kursk-II will replace the currently operating Kursk NPP, which comprises four ageing RBMK reactors, with four new Generation 3+ VVER-TOI reactors. Unit 1 began commercial operation at the end of April. Unit 2 is expected to begin operation in 2027. The older RBMK units are especially vulnerable to attack as they have no hardened containment.

The Kursk NPP has been the target of several military actions and drone strikes. The most notable was in August 2025 when a drone detonated and damaged an auxiliary transformer, sparking a structural fire. The IAEA monitored the event and confirmed radiation levels remained normal.

库尔斯克二期将取代现运行的库尔斯克核电站(由4台老化RBMK反应堆组成),新建4台三代+VVER-TOI反应堆。1号机组4月底投入商业运行,2号机组预计2027年投运。老旧RBMK机组尤其易受攻击,因其没有加固安全壳。

库尔斯克核电站多次成为军事行动与无人机袭击目标。最严重的是2025年8月一架无人机引爆并损坏一台辅助变压器,引发结构火灾。IAEA监测该事件并确认辐射水平保持正常。

48. 日本 Hamaoka(滨冈)核电数据丑闻持续发酵

英文全文:

Japan's Nuclear Regulation Authority (NRA) has accused Chubu Electric Power Co of manipulating data following a regulatory investigation into its fraudulent earthquake risk data relating to the Hamaoka NPP. "We suspect there was a cover-up," NRA Chairman Shinsuke Yamanaka said. "I feel there was malicious intent."

NRA instructed its secretariat to investigate whether Chubu Electric executives were involved. Chubu Electric used a method different from what was reported to the NRA to estimate a maximum seismic ground motion during safety screenings for units 3&4. The company allegedly underestimated the maximum seismic ground motion by selecting favourable data while suggesting the figures came from proper calculation. Such irregularities are believed to have been carried out across multiple departments.

The NRA secretariat said Chubu Electric retroactively collected and rewrote data linked to the cherry-picking after hearings began in May 2025, affecting 69 of the 225 data sets. Chubu told NRA it had randomly collected 20 seismic wave data points and selected data close to the average, when it had actually asked a contractor to select favourable data from more than 1,000 points; in some cases nearly 30,000 data points were involved.

The Hamaoka plant sits directly above a major subduction zone near the intersection of two tectonic plates, making it highly vulnerable to earthquakes. It consists of five BWRs. Units 1&2 were retired in 2009; units 3-5 were shut down after the 2011 earthquake and tsunami. Chubu Electric built a 22-metre sea wall and applied for safety screenings to restart units 3&4.

中文翻译:

日本核监管局(NRA)指控中部电力公司(Chubu Electric)在针对滨冈核电站造假地震风险数据的监管调查中存在数据操纵。NRA主席Yamanaka Shinsuke表示:"我们怀疑存在掩盖行为,我认为有恶意意图。"

NRA已指示其秘书处调查中部电力高管是否牵涉其中。中部电力在3、4号机组重启安全审查中,使用了与向NRA报告不同的方法估算最大地震地面运动。公司据称通过选择有利数据低估了最大地震地面运动,同时暗示数据来自正规计算。此类违规行为据信跨多个部门实施。

NRA秘书处表示,中部电力在2025年5月听证开始后追溯收集并重写了与"摘樱桃"相关的数据,影响225组数据中的69组。中部电力告诉NRA其随机收集了20个地震波数据点并选择接近平均值的数据,实际上却要求承包商从1000多个点中选择有利数据;某些情况下涉及近3万个数据点。

滨冈核电站正位于两大板块交汇处的主要俯冲带之上,极易受地震影响。它由5台沸水堆组成。1、2号机2009年退役;3-5号机在2011年地震海啸后停机。中部电力修建了22米高防波堤并申请安全审查以重启3、4号机。

51. Oklo 的 Groves 项目通过安全里程碑

英文全文(节选):

The US Department of Energy (DOE) has approved the Documented Safety Analysis (DSA) for Oklo's Groves Isotope Test Reactor in Lockhart, Texas. This key approval under the Reactor Pilot Program (RPP) marks completion of the project's final safety documentation and advances the reactor into its final pre-startup phase.

The Groves facility features a 15 MWt pool-type, water-cooled, non-pressurised advanced reactor using low-enriched uranium fuel. It is the first advanced reactor project on privately owned land to secure DSA approval using entirely commercially sourced fuel, equipment, and systems. The plant will not generate electricity; instead it is dedicated to creating a domestic supply chain for critical medical and industrial radioisotopes.

With the DSA locked in, Groves must navigate a short checklist before full operations: a DOE Readiness Review, formal federal approval, fuel loading and initialisation testing. Oklo is targeting first criticality for Groves in July.

Groves is based on a Versatile Isotope Production Reactor (VIPR) system. The reactor core sits submerged at the bottom of a deep, unpressurised pool. The pool water serves as a static radiation shield and thermal heat sink. Specialised irradiation tubes line the core perimeter; technicians insert stable target materials to be transmuted into high-purity radioisotopes. Irradiated material is shipped to the Idaho Radiochemistry Laboratory to be refined into clinical-grade medicine.

Oklo co-founder and CEO Jacob DeWitte said Groves is the first advanced reactor project to receive DSA approval on privately owned land with wholly commercially sourced fuel, equipment and systems. Less than a year after breaking ground, Groves is advancing toward criticality, demonstrating advanced nuclear can move from an open field to deployment on a commercial timeline.

Oklo is executing a dual-track regulatory strategy: leveraging DOE authority for pilot deployments while advancing broad commercial licensing with the NRC. The company achieved several accelerated milestones under the ADVANCE Act; NRC accepted the final report for review in just 15 days instead of 60. Oklo's Ohio project aims to deliver 1.2 GWe; in early 2026 Oklo signed a landmark agreement with Meta Platforms to support its data centres and AI supercluster.

美国能源部(DOE)已批准Oklo位于德州Lockhart的Groves同位素试验堆的《文件化安全分析》(DSA)。这一反应堆试点计划(RPP)下的关键批准标志着项目最终安全文件编制完成,并推动反应堆进入启动前最后阶段。

Groves设施采用15 MWt池式、水冷、非承压先进反应堆,使用低浓缩铀燃料。它是首个在私有土地上、完全采用商业化来源燃料/设备/系统获得DSA批准的先进反应堆项目。该电站不发电,而是致力于建立用于癌症治疗、空间探索和国家安全的关键医用与工业同位素国内供应链。

DSA锁定后,Groves在全面运行前需完成简短清单:DOE准备度审查、联邦正式批准、装料与初始化试验。Oklo目标7月实现Groves首次临界。

Groves基于"通用同位素生产反应堆"(VIPR)系统。堆芯浸没在深而不承压的水池底部,池水作为静态辐射屏蔽与热阱。堆芯周边布置专用辐照管,技术人员插入稳定靶材以嬗变为高纯同位素。辐照后的材料运至爱达荷放射化学实验室精炼为临床级药物。

Oklo联合创始人兼CEO Jacob DeWitte表示,Groves是首个在私有土地上、完全采用商业化来源燃料/设备/系统获得DSA批准的先进反应堆项目。破土不到一年,Groves正迈向临界,证明先进核能可按商业时间表从空地走向部署。

Oklo执行双轨监管策略:利用DOE权限推进试点部署,同时与NRC推进广泛商业取照。公司在ADVANCE法案下取得多项加速里程碑;NRC仅用15天(而非惯例60天)接受最终报告审查。Oklo的俄亥俄项目目标提供1.2 GWe;2026年初Oklo与Meta Platforms签署里程碑协议,支持其数据中心与AI超级集群。

52. Aalo Atomics 试验堆在 INL 实现临界(7 月 4 日前第四座 DOE 授权先进堆)

  • 来源:Power Magazine | 作者:Sonal C. Patel | 日期:2026-07-06

  • 原文链接

英文原文

Aalo Atomics' Test Reactor Reaches Criticality at INL, Fourth DOE-Authorized Advanced Reactor by July 4

Aalo Atomics' Aalo-X Critical Test Reactor (CTR)—dubbed "Project First Light"—has reached criticality at Idaho National Laboratory (INL), marking the fourth Department of Energy (DOE)–authorized advanced reactor startup under the federal push to accelerate reactor testing and demonstration.

The U.S. Department of Energy (DOE) said July 6 that Aalo's test reactor, which DOE referred to as Aalo-X, "successfully completed a zero-power fueled criticality demonstration" at INL under DOE's Reactor Pilot Program. Aalo told POWER the Critical Test Reactor reached criticality at 12:20 a.m. MT on July 4, allowing DOE to exceed the target in Executive Order 14301, which directed the department to approve at least three reactors to reach criticality by July 4, 2026.

"President Trump asked for three advanced reactors to be authorized and achieve criticality by the 250th anniversary of our great country," Energy Secretary Chris Wright said in DOE's July 6 statement. "I'm pleased to share that through the dedication and hard work of Aalo, INL, and DOE, we have surpassed that ask and delivered four!"

Aalo follows Antares Nuclear's Mark-0 reactor, which reached criticality at INL on June 4, and Valar Atomics' Ward 250 reactor, which reached criticality at the Utah San Rafael Energy Lab on June 18, as the third Reactor Pilot Program developer to reach the milestone. Deployable Energy's Unity reactor reached zero-power criticality at INL on June 30 through DOE's Nuclear Energy Launch Pad initiative, making Aalo the fourth DOE-authorized advanced reactor criticality in a month.

As Yasir Arafat, Aalo president and chief technology officer, explained in a July 2 post on X, after Aalo had begun fuel loading, "Criticality is not the birth of fission. It's the moment when the reactor no longer depends on an external neutron source to sustain the chain reaction." In reactor-physics terms, Aalo's CTR crossed from subcritical operation, where k < 1 and each neutron generation produces fewer fissions than the last, to critical operation, where k = 1 and each generation sustains the next.

"The hardest problem in nuclear was never the physics, our country simply forgot how to build," Arafat said in DOE's July 6 announcement. "The success of the Department of Energy Reactor Pilot Program is proof America can execute again." Arafat also noted that Aalo went "from breaking ground to a sustained chain reaction in just eight months," calling it "one of the fastest reactor builds in modern American history."

Inside Aalo's Five-Hour Criticality Run

In this five-hour livestream made public on July 6, 2026, Aalo Atomics documents the July 4 startup sequence that brought its Critical Test Reactor (CTR) to initial criticality at 12:20 a.m MT. The stream opens as operators are loading shim rods and the 13th fuel assembly, the number Aalo said its calculations indicated would be needed to sustain a chain reaction. Yasir Arafat explains criticality as the point at which neutron generation in the core balances neutron losses from leakage or absorption, stressing that the approach is "a very slow and deliberate process" that requires control mechanisms to be withdrawn in small, measured steps, with neutron counts taken at each step, and measured behavior checked against the company's physics model before operators can proceed.

The livestream then proceeds through the CTR core and startup sequence. The configuration comprises a roughly full-scale Aalo-X fuel load arranged in a hexagonal lattice, a geometry Aalo said was inspired by historical sodium-graphite reactor designs, including the Hallam Nuclear Power Facility, and chosen to preserve core symmetry and make reactor behavior more predictable during transients. The core includes 13 uranium dioxide fuel assemblies enriched to about 5%, graphite moderation to slow neutrons enough to sustain the chain reaction, neutron detectors around the core barrel, four safety rods, six control rods, and shim rods to manage excess neutrons. After the final assembly was loaded, operators entered Mode 1 operations, fully withdrew the safety rods, and began withdrawing control rods toward an estimated critical position (ECP), stopping repeatedly to collect neutron count data and recalculate the ECP.

As the core neared criticality, operators switched to a wide-range neutron monitoring instrument and moved individual control rods to about 79.3 inches before the control room declared, "The reactor is critical!"

Aalo officials said the project moved from construction to criticality in under eight months, including a reactor building completed in 36 days, a reactor built in the company's factory in 28 days, and 540 fuel rods assembled in two and a half days.

A Full-Scale Reactor Physics Campaign for Aalo-X

During a June 24 tour of Aalo's two-acre INL site, Arafat told POWER the CTR campaign is geared to test four key execution questions: whether the company can build a nuclear facility quickly, factory-fabricate reactor hardware, establish a repeatable fuel pathway, and stand up an operating organization under DOE authorization. The criticality milestone marks a significant technical step in Aalo's broader Aalo-X program, which is moving in stages from zero-power reactor physics to sodium systems testing, full-power operation, electricity production, and eventual deployment of Aalo's commercial Pod configuration.

"The Aalo-X design uses low-enriched uranium dioxide fuel, graphite moderation, and liquid sodium to produce a thermal neutron spectrum. Its primary reactor vessel uses a hybrid loop-pool configuration that houses the core, control rods, pumps, and heat exchangers in a single sealed tank, while its secondary sodium loop transfers heat to the steam generator, keeping water separate from radioactive primary sodium."

"Reaching criticality is our most significant milestone to date, as it paves the way for the deployment of the Aalo Pod to power commercial data centers once it receives authorization from the Nuclear Regulatory Commission," Matt Loszak, Aalo's CEO, said in the company's July 6 release. "More importantly, the Aalo-X Critical Test Reactor has the same full-scale core components as our commercial reactors. The Aalo-X's 10 MWe reactor design positions it as the premier power provider for the modern data center."

However, "Criticality is just the beginning," Arafat noted on July 6. "In the coming months, we will continue building and testing multiple reactors, including the commercial Aalo Pod design, which in the next 18 months will provide a scalable and affordable power option to data centers and enterprises."

Next Steps: From CTR to Aalo-0 to Aalo-X to Aalo Pod

Last week at the CTR, the final startup sequence kicked off following a series of DOE authorization milestones, including a final readiness assessment. After Energy Secretary Chris Wright signed the final approval to load fuel, the company was able to "flip the switch" and achieve criticality. "Aalo's celebration was intentionally reminiscent of Chicago Pile-1 (CP-1), the first self-sustaining, controlled nuclear chain reaction that occurred 84 years ago on December 2, 1942," the company noted.

Now that the CTR has achieved criticality, the campaign is slated to conduct controlled reactivity insertion tests, axial flux profiling with movable neutron detectors and flux wires, control rod calibration, shutdown-margin tests, and abnormal-configuration tests involving fuel or moderator changes. Those experiments are intended to qualify neutronics codes, verify reactivity margins, calibrate in-core instrumentation, and establish control behavior before Aalo-X operates at power.

Near the CTR, Aalo is assembling Aalo-0, a full-scale, non-nuclear prototype designed to circulate 60,000 pounds of sodium under operating conditions and test heat-transport and power-conversion systems, including heat exchangers, plugging meters, cold traps, heat tracing, instrumentation and controls, welds, modules, and operating procedures. Modules for Aalo-0 were built at the company's Austin manufacturing facility and shipped to Idaho, and Aalo says the system is slated for commissioning in fall 2026.

Loszak told reporters during the June 24 tour that Aalo intentionally split the test program into two full-scale campaigns—a fueled reactor-physics campaign in the CTR and a separate sodium campaign on the same INL site—because the approach allows Aalo to test "the nuclear fuel portion" and "the coolant, the sodium coolant" in isolation before combining them in a power-producing system.

The next major undertaking is Aalo-X, the full-power 30-MWth/10-MWe sodium-cooled demonstration nuclear power plant at INL authorized under DOE's Reactor Pilot Program. Aalo says the plant will use data from the CTR and Aalo-0 to support construction and licensing in 2027, followed by demonstrations of operations and safety mechanisms in 2028. The demonstration is intended to prove the 10-MWe Aalo-1 reactor for the company's commercial 50-MWe Pod, which would use five 10-MWe reactors connected to a shared turbine.

This week, Aalo announced it had already begun work on the second nuclear reactor on the Aalo-X campus at INL. Dubbed "Project Ascension," the test commercial-scale system will "produce electricity and power for an on-site data center in the coming months," the company said. Loszak said excavation and earthwork for the second full-scale reactor had been completed the week before the milestone and that the company was preparing to pour first concrete. Aalo expects to finish the reactor by the end of 2026 and "make electrons at commercial scale" in 2027.

The data center pairing is also tied to Aalo's broader digitalization plan. In March, Microsoft said it was working with NVIDIA and Aalo on AI-for-nuclear tools intended to streamline permitting, accelerate design, and optimize operations. Microsoft said its Generative AI for Permitting solution reduced Aalo's time-intensive permitting process by 92%, with estimated savings of $80 million a year.

Ultimately, as Arafat wrote in February, Aalo seeks Technology Readiness Level 9 by running Aalo-X at full 30-MWth power, generating 10 MWe, accumulating fuel burnup, demonstrating safety systems, handling transients such as rapid load changes and pump trips, and exercising refueling procedures. Aalo expects the reactor to run at 100% power for sustained periods, including a 100-hour endurance run.

Speed to Power: Supply Chain, Factory Fabrication, and Field Assembly

For Aalo, while the Reactor Pilot Program ramped up its schedule, its speed-to-power ambitions were already embedded in a long-held strategy. Aalo embraced the EO 14301 deadline "as a forcing function to innovate and iterate faster."

One benefit was that Aalo had already planned to build up its internal capabilities and close partnerships in a form of vertical integration. Arafat said the structure was designed to keep Aalo from getting stuck in "contractual limbo" or waiting on "another organization's timeline."

On the design side, Aalo's engineering team handles core and system design for Aalo-X, drawing on decades of sodium reactor experience from systems such as the Experimental Breeder Reactor-II (EBR-II), the Sodium Reactor Experiment (SRE), and Hallam, while developing and testing the integration.

And, rather than place the CTR in an existing DOE facility, Aalo chose to build its own reactor building. The company has also tailored its reactivity control and protection systems to Aalo-X rather than buying an off-the-shelf reactor instrumentation and control system. Aalo has been training its own operations crew, including former Navy nuclear submarine reactor operators and test engineers.

Aalo's factory model was as pivotal. At Aalo's 40,000-square-foot manufacturing facility in Austin, Texas, crews fabricated reactor modules and assemblies in-house. Aalo has said it is now expanding into a one-million-square-foot factory to apply assembly-line manufacturing to reactor production and support mass production of the Aalo Pod.

To secure fuel on Aalo-X's timeline, Aalo leaned heavily on self-reliance. "Rather than wait in queue for someone else's fuel, or one-off handout from DOE for the first reactor, Aalo took charge of the fuel cycle for Aalo-X," Arafat wrote. Aalo secured low-enriched uranium feedstock early, including fresh enriched uranium hexafluoride from Urenco. For the CTR, Aalo used fuel rods fabricated by Global Nuclear Fuel (GNF), GE Vernova's nuclear fuel arm. While the CTR uses 4.95% enriched uranium dioxide fuel, Arafat said Aalo built enough low-enriched uranium dioxide fuel assemblies "to ultimately produce 30 MWth," from which the company can extract 10 MWe. The commercial reactor is expected to use standard uranium oxide fuel enriched between 5% and 8%, rather than high-assay low-enriched uranium (HALEU).

Four DOE-Authorized Criticalities, Four Different Reactor Cases

Aalo's criticality capped a month in which DOE-authorized projects reached criticality across different reactor concepts, sites, fuels, and authorization pathways. Antares Nuclear's Mark-0 reactor reached criticality at INL on June 4, becoming the first advanced reactor to do so under DOE's Reactor Pilot Program. Mark-0 is a HALEU, TRISO-fueled, sodium heat-pipe-cooled microreactor. Valar Atomics' Ward 250 reactor reached criticality at the Utah San Rafael Energy Lab on June 18, becoming the second Reactor Pilot Program project. Ward 250 is a TRISO-fueled modular high-temperature gas reactor (HTGR) using helium coolant. Deployable Energy's Unity reactor reached zero-power criticality at INL on June 30 through DOE's Nuclear Energy Launch Pad initiative. Unity is a water-moderated, helium-cooled microreactor using 4.95% enriched LEU uranium dioxide fuel. Aalo's CTR is the fourth reactor.

The next Reactor Pilot Program candidate poised to achieve criticality is Oklo Isotopes' Groves Isotope Test Reactor in Texas, an isotope-production test reactor. Oklo said on July 1 that the DOE had approved the DSA for Groves. Radiant Nuclear is also approaching fueled testing at INL, having taken possession of INL's Demonstration of Microreactor Experiments (DOME) facility on April 1, 2026. On July 1, Radiant said it had received its first tranche of TRISO fuel at DOME, fabricated by Standard Nuclear in Oak Ridge, Tennessee.

Aalo Atomics 的试验堆在 INL 实现临界,成为 7 月 4 日前第四座 DOE 授权的先进反应堆

Aalo Atomics 的 Aalo-X 临界试验堆(CTR,代号"Project First Light / 第一缕光计划")已在爱达荷国家实验室(INL)实现临界,这是联邦政府推动反应堆测试与示范加速计划下,第四座获得能源部(DOE)授权的先进反应堆启动。

美国能源部(DOE)于 7 月 6 日表示,Aalo 的试验堆(DOE 称之为 Aalo-X)在 INL 的"反应堆试点计划"(Reactor Pilot Program)下"成功完成了零功率装料临界演示"。Aalo 告诉 POWER,该临界试验堆于 7 月 4 日凌晨 12:20(山区时间)达到临界,使 DOE 超额完成了第 14301 号行政命令设定的目标——该命令要求 DOE 在 2026 年 7 月 4 日前批准至少三座反应堆实现临界。

"特朗普总统要求在美国建国 250 周年前批准三座先进反应堆并实现临界,"能源部长 Chris Wright 在 DOE 7 月 6 日的声明中说,"我很高兴地宣布,在 Aalo、INL 和 DOE 的奉献与努力下,我们不仅达标,还交付了四座!"

Aalo 继 Antares Nuclear 的 Mark-0 堆(6 月 4 日在 INL 临界)、Valar Atomics 的 Ward 250 堆(6 月 18 日在犹他州 San Rafael 能源实验室临界)之后,成为反应堆试点计划下第三家达成该里程碑的开发商。Deployable Energy 的 Unity 堆于 6 月 30 日在 INL 通过 DOE 的"核能发射台"(Nuclear Energy Launch Pad)计划实现零功率临界,使 Aalo 成为一个月内第四座获得 DOE 授权的先进反应堆临界。

Aalo 总裁兼首席技术官 Yasir Arafat 在 7 月 2 日的 X 帖子中解释:临界"并非裂变的诞生,而是反应堆不再依赖外部中子源来维持链式反应的时刻"。从反应堆物理角度,Aalo 的 CTR 从次临界(k < 1,每一代产生的中子比上一代少)跨越到临界(k = 1,每一代维持下一代)。

"核能最难的问题从来不是物理,而是我们的国家忘记了如何建造,"Arafat 在 DOE 7 月 6 日的公告中说,"DOE 反应堆试点计划的成功证明美国能够再次执行。"Arafat 还指出 Aalo"从破土到持续链式反应仅用八个月",称其为"现代美国史上最快的反应堆建造之一"。

Aalo 五小时临界运行内幕

在 2026 年 7 月 6 日公开的这段五小时直播中,Aalo Atomics 记录了 7 月 4 日的启动序列,其临界试验堆于凌晨 12:20(MT)达到初始临界。直播开始时,操作员正在装入补偿棒和第 13 个燃料组件——Aalo 称其计算表明维持链式反应需要 13 个组件。Arafat 将临界解释为堆芯中子产生与泄漏/吸收损失相平衡的时刻,强调该过程"非常缓慢且审慎",需要以小步、可测量地抽出控制机构,每步记录中子计数,并将实测行为与公司的物理模型比对后方可继续。

直播继续展示 CTR 堆芯与启动序列。堆芯配置约为全尺寸 Aalo-X 燃料装载,呈六边形栅格布置——Aalo 称其几何启发自历史上的钠-石墨反应堆设计(包括 Hallam 核电站),旨在保持堆芯对称性并使瞬态行为更可预测。堆芯包括 13 个约 5% 富集的二氧化铀燃料组件、用于慢化中子的石墨、堆芯筒周围的中子探测器、4 根安全棒、6 根控制棒,以及管理多余中子的补偿棒。装入最后一个组件后,操作员进入 Mode 1 运行,完全抽出安全棒,并开始向估计临界位置(ECP)抽出控制棒,反复停下收集中子计数数据并重算 ECP。

随着堆芯接近临界,操作员切换到宽量程中子监测仪表,将各控制棒移动到约 79.3 英寸,随后控制室宣布"反应堆临界!"

Aalo 官员表示,项目从施工到临界不到八个月,包括 36 天建成反应堆厂房、28 天在工厂建成反应堆、两天半组装 540 根燃料棒。

Aalo-X 的全尺寸反应堆物理攻坚

在 6 月 24 日对 Aalo 两英亩 INL 厂区的参观中,Arafat 告诉 POWER,CTR 攻坚旨在验证四个关键执行问题:能否快速建造核设施、能否工厂化制造反应堆硬件、能否建立可重复的燃料路径、能否在 DOE 授权下组建运行组织。临界里程碑是 Aalo 更广泛 Aalo-X 计划的重要技术步骤,该计划正分阶段从零功率反应堆物理,走向钠系统测试、全功率运行、发电,最终部署 Aalo 商用 Pod 配置。

"Aalo-X 设计采用低浓缩二氧化铀燃料、石墨慢化和液态钠产生热中子能谱。其主反应堆容器采用混合回路-池式构型,将堆芯、控制棒、泵和热交换器容纳于单一密封罐内,而二次钠回路将热量传递给蒸汽发生器,使水与放射性一次钠隔离。"

"达到临界是我们迄今最重要的里程碑,因为它为 Aalo Pod 在获得核管会(NRC)授权后部署为商业数据中心供电铺平了道路,"Aalo CEO Matt Loszak 在公司 7 月 6 日发布中说,"更重要的是,Aalo-X 临界试验堆拥有与我们商用反应堆相同的全尺寸堆芯部件。Aalo-X 的 10 MWe 反应堆设计使其成为现代数据中心首选的电力供应商。"

然而,"临界只是开始,"Arafat 在 7 月 6 日指出,"未来几个月,我们将继续建造和测试多座反应堆,包括商用 Aalo Pod 设计,未来 18 个月它将为数据中心和企业提供可扩展、经济高效的电力选项。"

下一步:从 CTR 到 Aalo-0 到 Aalo-X 到 Aalo Pod

上周在 CTR,在一系列 DOE 授权里程碑(包括最终就绪评估)之后,最终启动序列启动。能源部长 Chris Wright 签署最终装料批准书后,公司得以"按下开关"实现临界。"Aalo 的庆祝有意致敬芝加哥堆-1(CP-1)——84 年前(1942 年 12 月 2 日)发生的首次自持、可控核链式反应,"公司指出。

CTR 实现临界后,该攻坚计划将进行受控反应性引入试验、带可移动中子探测器和通量丝的轴向通量分布测量、控制棒校准、停堆裕度试验,以及涉及燃料或慢化剂变更的异常构型试验。这些实验旨在 qualifying 中子学代码、验证反应性裕度、校准堆芯内仪表,并在 Aalo-X 功率运行前确立控制行为。

在 CTR 附近,Aalo 正在组装 Aalo-0——一座全尺寸、非核原型,设计用于在操作条件下循环 60,000 磅钠,并测试传热和功率转换系统,包括热交换器、堵塞计、冷阱、伴热、仪表与控制、焊接、模块和运行程序。Aalo-0 的模块在公司的奥斯汀制造厂建造并运往爱达荷,Aalo 称该系统计划于 2026 年秋季调试。

Loszak 在 6 月 24 日参观中告诉记者,Aalo 有意将测试计划拆分为两个全尺寸攻坚——CTR 中的装料反应堆物理攻坚,以及同一 INL 厂区的独立钠攻坚——因为这种方法使 Aalo 能在组合成发电系统之前,分别测试"核燃料部分"和"冷却剂、钠冷却剂"。

下一个主要任务是 Aalo-X——INL 内全功率 30-MWth/10-MWe 钠冷示范核电站,经 DOE 反应堆试点计划授权。Aalo 称该电厂将利用 CTR 和 Aalo-0 的数据支持 2027 年建造与取证,随后在 2028 年进行运行与安全机制示范。该示范旨在验证 10-MWe Aalo-1 反应堆,用于公司商用 50-MWe Pod(由五座 10-MWe 反应堆连接共享涡轮)。

本周,Aalo 宣布已开始在 INL 的 Aalo-X 厂区建造第二座核反应堆。代号"Project Ascension / 升天计划",该商用规模测试系统"将在未来数月为现场数据中心发电供能",公司称。Loszak 表示第二座全尺寸反应堆的土方工程已在里程碑前一周完成,公司正准备浇筑第一方混凝土。Aalo 预计 2026 年底前完成该反应堆,并于 2027 年"以商业规模发电"。

数据中心配对也与 Aalo 更广泛的数字化计划相关。3 月,微软表示正与 NVIDIA 和 Aalo 合作开发"AI for Nuclear"工具,以简化许可、加速设计、优化运行。微软称其"生成式 AI 许可方案"将 Aalo 耗时的许可流程缩短了 92%,估计每年节省 8000 万美元。

最终,正如 Arafat 在 2 月所写,Aalo 力求通过在全功率 30-MWth 下运行 Aalo-X、产生 10 MWe、积累燃料燃耗、演示安全系统、处理快速负荷变化与泵跳闸等瞬态、并演练换料程序,达到技术就绪等级 9(TRL 9)。Aalo 预计反应堆将以 100% 功率持续运行,包括 100 小时耐久运行。

快速供电:供应链、工厂制造与现场装配

对 Aalo 而言,尽管反应堆试点计划加快了进度,但其"快速供电"雄心早已植根于长期战略。Aalo 将 EO 14301 截止期视为"创新和更快迭代的助推器"。

一个好处是 Aalo 已计划通过某种垂直整合建立内部能力和紧密合作。Arafat 表示这种结构旨在避免 Aalo 陷入"合同僵局"或等待"其他组织的时间表"。

在设计方面,Aalo 工程团队负责 Aalo-X 的堆芯与系统设计,借鉴实验增殖堆-II(EBR-II)、钠冷实验堆(SRE)和 Hallam 等系统的数十年钠冷堆经验,同时开发并测试集成。

而且,Aalo 没有将 CTR 放在现有 DOE 设施中,而是选择自建反应堆厂房,Arafat 称这是摆脱制约过去核项目的缓慢、定制建造模式的一部分。

公司还为 Aalo-X 量身定制了反应性控制与保护系统,而非购买现成反应堆仪控系统。Aalo 一直在培训自己的运行团队,包括前海军核潜艇反应堆操作员和测试工程师。

Aalo 的工厂模式同样关键。在得州奥斯汀 40,000 平方英尺的制造厂,员工在内部制造反应堆模块和组件。Aalo 表示正扩建至 100 万平方英尺工厂,将流水线制造应用于反应堆生产并支撑 Aalo Pod 的批量生产。

为保障 Aalo-X 时间线上的燃料,Aalo 高度依赖自力更生。"与其排队等别人的燃料,或等 DOE 给第一座反应堆一次性施舍,Aalo 主动掌控了 Aalo-X 的燃料循环,"Arafat 写道。Aalo 早早锁定了低浓缩铀原料,包括来自 Urenco 的新鲜富集六氟化铀。对于 CTR,Aalo 使用了 Global Nuclear Fuel(GNF,GE Vernova 核燃料部门)制造的燃料棒。虽然 CTR 使用 4.95% 富集二氧化铀燃料,Arafat 称 Aalo 建造了足够的低浓缩二氧化铀燃料组件"最终可产生 30 MWth",并从中提取 10 MWe。商用反应堆预计使用 5%–8% 富集的标准氧化铀燃料,而非高丰度低浓缩铀(HALEU)。

四座 DOE 授权临界,四种不同反应堆案例

Aalo 的临界为一个月的收官——DOE 授权项目在不同反应堆概念、场址、燃料和授权路径上实现临界。Antares Nuclear 的 Mark-0 于 6 月 4 日在 INL 临界,成为反应堆试点计划下首座实现临界的先进反应堆,其为 HALEU、TRISO 燃料、钠热管冷却微堆。Valar Atomics 的 Ward 250 于 6 月 18 日在犹他州 San Rafael 能源实验室临界,成为第二座,其为 TRISO 燃料模块化高温气冷堆(HTGR),使用氦冷却剂。Deployable Energy 的 Unity 于 6 月 30 日通过 DOE"核能发射台"计划在 INL 实现零功率临界,其为水慢化、氦冷微堆,使用 4.95% 富集 LEU 二氧化铀燃料。Aalo 的 CTR 是第四座。

下一个有望实现临界的反应堆试点计划候选者是 Oklo Isotopes 在得州的 Groves 同位素试验堆。Oklo 于 7 月 1 日表示 DOE 已批准 Groves 的文件化安全分析(DSA)。Radiant Nuclear 也接近在 INL 进行装料测试,于 2026 年 4 月 1 日接管了 INL 的微堆实验示范(DOME)设施。7 月 1 日,Radiant 表示已在 DOME 收到首批 TRISO 燃料,由田纳西州橡树岭的 Standard Nuclear 按其规格制造。

英文原文

Deployable Energy's Unity Nuclear Reactor Achieves Criticality at INL, Third Under DOE Nuclear Push

Deployable Energy's Unity demonstration reactor has achieved criticality at Idaho National Laboratory (INL), making it the third Department of Energy (DOE)–authorized advanced reactor to reach the milestone ahead of the July 4 deadline set under President Trump's May 2025 nuclear executive order.

The U.S. DOE on July 1 said Deployable Energy's Unity reactor completed a zero-power fueled criticality demonstration late June 30 at INL as part of the Nuclear Energy Launch Pad initiative, which is managed by the National Reactor Innovation Center (NRIC) at INL.

Unity follows Antares Nuclear's Mark-0 reactor, a sodium heat-pipe-cooled microreactor fueled with high-assay low-enriched uranium (HALEU) tri-structural isotropic (TRISO) fuel, which reached criticality at INL on June 4, and Valar Atomics' Ward 250 reactor, a TRISO-fueled modular high-temperature gas reactor (HTGR) using helium coolant, which reached criticality at the Utah San Rafael Energy Lab in Emery County and began power ascension on June 18.

Criticality is the point at which a nuclear fission chain reaction becomes self-sustaining. Zero-power criticality is a low-power physics demonstration in which the core reaches a controlled, self-sustaining chain reaction without producing meaningful thermal output or electricity. Unity achieved criticality "safely and as planned following a comprehensive testing and startup program conducted in collaboration with Idaho National Laboratory and under applicable regulatory requirements," Deployable said on Wednesday.

According to the DOE, the milestone marks the agency's "fulfillment of a precedent-setting directive to reignite nuclear energy innovation in the U.S." under Executive Order (EO) 14301. The May 2025 order directed the DOE to first, expedite qualified test reactors at DOE-owned or DOE-controlled facilities; and second, establish "a pilot program for reactor construction and operation outside the National Laboratories" under DOE's authority, with a goal of approving at least three reactors to reach criticality by July 4, 2026.

On Wednesday, the DOE said the three milestones make the U.S. "the first country in history to achieve criticality in three unique advanced microreactor designs in a single month."

Unity's Bet: CANDU-Like Geometry Without CANDU Supply-Chain Burden

Houston-based Deployable Energy is developing Unity as a 1-MWe-class microreactor platform for behind-the-meter power applications, including national security facilities, data centers, maritime uses, remote industrial sites, and process heat. During a tour hosted by INL on June 24, company officials described Unity as a water-moderated, gas-cooled microreactor that uses 4.95% enriched low-enriched uranium (LEU) uranium dioxide (UO2) fuel, helium coolant, and commercially available materials rather than high-assay low-enriched uranium, graphite moderation, heat pipes, or more specialized advanced-reactor supply chains.

The test reactor at INL uses a calandria-style water-moderated geometry, but as Sanjay Mukhi, Deployable's co-founder and chief commercial officer, told POWER, the design is separate and does not depend on CANDU intellectual property. Company officials described the test reactor more broadly as a combination of light-water reactor (LWR), HTGR, and calandria design features. Water provides moderation, helium removes heat, and standard LEU UO2 fuel keeps the system closer to existing commercial fuel infrastructure, they explained.

While an earlier Deployable concept looked more like a conventional advanced microreactor—HALEU-fueled, graphite-moderated, and heat-pipe-based—Mukhi said Deployable concluded it would be too expensive and too constrained by fuel and supply chain availability. Mukhi summarized the design philosophy this way: "Let's use what's readily available," he said. "Let's not use exotic materials, let's not use things that are hard to fabricate. Let's use what we can easily get our hands on." The challenge was to preserve safety and performance while using commercially available materials and fabrication routes, he added.

A 150-Day Delivery

Deployable, one of four selections under the Nuclear Launch Pad initiative unveiled in April 2026, began working with INL at the start of the year and moved from project kickoff to a delivered reactor, delivered fuel, and readiness for criticality in a stunning period of roughly 150 days, with a "single-digit million" dollar investment, as CEO and co-founder Bobby Gallagher said in a video released after the criticality milestone.

The schedule was part of the demonstration, Gallagher noted on Wednesday. "What makes Deployable's story so remarkable is how we have achieved this milestone. It is the speed of execution," he said, noting that the company's rapid progress rested on three pillars: its technology architecture, which uses existing materials and low-enriched uranium alongside mass-manufacturable processes; supply chain availability, underpinned by "phenomenal partnerships" across vendors and national labs; and a deeply experienced team drawn from the research, commercial, and naval reactor worlds.

Gallagher also noted that the INL campaign was supported by more than 100 highly experienced INL staff, the U.S. DOE's Office of Nuclear Energy, and "champions" such as DOE Deputy Assistant Secretary for Nuclear Reactors Dr. Rian Bahran and Bob Boston, DOE manager of the Idaho Operations Office. It was also "witnessed" by the Nuclear Regulatory Commission (NRC). The rapid deployment will inform Deployable's commercial ambition, which is to deliver systems to customer sites and achieve "speed to power in less than six months," he noted.

As Lance Maul, Deployable's co-founder and chief operating officer, explained during the June 24 tour, Unity's path to criticality centered on an incremental fuel-loading campaign. Rather than jumping straight to the full configuration, the team increased reactivity in small steps, measured the response at each stage, and repeatedly returned the system to a comfortably subcritical state before proceeding.

INL's existing infrastructure was also central to the rapid schedule. Mukhi said Unity's small size allowed the team to use an existing facility rather than build a new test structure, noting that INL personnel told the company the reactor could "fit through the doorway." The test was installed in an existing neutron radiography space at INL's North Beam Station, where thick shielding, removable shield plugs, and a deep floor pit were already available. The setup is approximately one-to-one in core size with the company's intended commercial configuration, Mukhi said.

Deployable's Next Steps Target a Commercial Pathway

For Deployable, the successful achievement of criticality for the Unity demonstration reactor now "marks the beginning of the next phase of testing and demonstration as Deployable Energy advances toward commercial deployment." Gallagher on Wednesday noted the company wants to move from the Unity test toward commercial reactors by 2028 and ultimately serve U.S. energy needs "from megawatt deployments to gigawatt deployments."

As POWER reported when DOE named the first Launch Pad developers, Deployable is developing the Unity Nuclear Battery (UNB) as a 1-MWe gas-cooled microreactor with an actively cooled helium primary loop and standard LEU UO2 fuel, engineered for factory manufacture and shipment in a standard 20-foot container for remote, distributed, maritime, and defense applications. Mukhi told POWER the company operates a 340,000-square-foot manufacturing facility on a 58-acre site in Houston with truck access, a rail spur, and machine, fabrication, paint, and blast shops, and said the facility is intended to support high-volume production of Unity units.

At the same time, because the NRC has been observing the DOE authorization process, Deployable expects to use the test results and processes in future licensing cases, Mukhi said. Deployable has said it has been engaged in NRC pre-application activities since October 2025 and has outlined a strategy that begins with a 10 CFR Part 50 Class 103 non-power production and utilization facility, and potentially leverages the NRC's newly proposed Part 57 framework for rapid, high-volume deployment of microreactors with comparable risk profiles.

A Critical First for the Nuclear Energy Launch Pad

Deployable's criticality experiment milestone marks the first completed under the Nuclear Energy Launch Pad, which the DOE launched in March 2026 to complement NRIC's test beds and to succeed two shorter-lived DOE programs, the Reactor Pilot Program, launched in June 2025, and the Fuel Line Pilot Program, launched in July 2025.

As POWER has reported, the Nuclear Energy Launch Pad program was created to provide a "broader, more flexible deployment pathway" for reactors, fuel-cycle projects, and supporting nuclear infrastructure on federal and non-federal lands. The Launch Pad initiative, notably, has two prongs: Launch Pad INL, which offers access to roughly 2,000 acres at INL, and Launch Pad USA, which can support projects at other DOE sites, national laboratories, and non-federal locations. DOE opened Launch Pad and the DOME test bed to applicants in June 2026, setting an initial July 8 submission deadline and later periodic reviews, while making clear that participants would bear project costs, including design, construction, operation, decommissioning, DOE authorization, and lab engagement expenses.

Significantly, however, Executive Order (EO) 14301, signed May 23, 2025, directed DOE to expedite qualified test reactors at DOE-owned or DOE-controlled facilities and separately establish "a pilot program for reactor construction and operation outside the National Laboratories" with a goal of approving at least three reactors to reach criticality by July 4, 2026.

Under the Reactor Pilot Program, the DOE accepted 11 projects from 10 companies: Aalo Atomics, Antares Nuclear, Atomic Alchemy, Deep Fission, Last Energy, Natura Resources LLC, Oklo (selected for two projects), Radiant Industries, Terrestrial Energy, and Valar Atomics. Of those, Antares and Valar have achieved criticality so far.

This week, "in a matter of days," as company officials told POWER, and before the July 4 deadline, Aalo Atomics is poised to achieve criticality at its Critical Test Reactor (CTR), dubbed "Project First Light", at its two-acre INL site.

As Aalo CEO and co-founder Matt Loszak revealed during the June 24 tour, the sodium-cooled, graphite-moderated, LEU UO2-fueled thermal-spectrum test reactor was built in 36 days after site work began and then outfitted with modules fabricated at Aalo's Austin factory and shipped to Idaho on standard highways. The test reactor is full-scale in geometry, fuel quantity, graphite inventory, and control-rod mechanisms, but it excludes sodium coolant for the initial criticality campaign.

On Wednesday, meanwhile, Oklo said the DOE had approved the Documented Safety Analysis (DSA) for Oklo Isotopes' (formerly known as Atomic Alchemy) Groves Isotope Test Reactor in Texas. The measure moves the private-land project into DOE's final pre-startup review process under the Reactor Pilot Program. Oklo said it is targeting first criticality for Groves in July 2026, but the milestone may be delayed past the July 4 deadline.

Groves is distinct from Oklo's larger Aurora-INL project, which is also part of the Reactor Pilot Program. The 75-MWe Aurora-INL project, a sodium-cooled fast reactor power plant, is under construction at INL, and Oklo plans to begin commercial operation in 2028.

Oklo has described Groves as a zero-power, one-reactor unit of a future multi-reactor isotope production facility, intended to give the company practice in designing, constructing, standing up, and operating a commercially relevant nuclear facility outside the national laboratory system. The company says Groves will help develop operating procedures, evaluate reactor system performance, validate isotope production processes, and support future domestic production of critical isotopes for medical, industrial, research, space, and national security uses.

"With approval of both the Preliminary and Documented Safety Analyses, Groves now moves into the final phase before startup, including readiness review, fuel loading, and criticality," Oklo co-founder and CEO Jacob DeWitte said. "Less than a year after breaking ground, Groves is advancing toward criticality and demonstrating that advanced nuclear can move from an open field to deployment on a commercial timeline and with a commercially representative facility. DOE demonstrated remarkable capabilities to review and reach this milestone for a facility of this type, and for a facility outside of a national laboratory on this timescale. As the first project of this nature to achieve this milestone under the DOE Reactor Pilot Program, Groves provides a blueprint for how the U.S. can accelerate advanced reactor deployment while maintaining a rigorous, practical safety process."

Deployable Energy 的 Unity 核反应堆在 INL 实现临界(DOE 推进下第三座)

Deployable Energy 的 Unity 示范堆已在爱达荷国家实验室(INL)实现临界,使其成为在特朗普总统 2025 年 5 月核能行政命令设定的 7 月 4 日截止期之前,第三座获得能源部(DOE)授权的先进反应堆达成该里程碑。

美国 DOE 于 7 月 1 日表示,Deployable Energy 的 Unity 反应堆于 6 月 30 日晚在 INL 完成"零功率装料临界演示",该演示属于由 INL 国家反应堆创新中心(NRIC)管理的"核能发射台"(Nuclear Energy Launch Pad)计划。

Unity 继 Antares Nuclear 的 Mark-0 堆(6 月 4 日在 INL 临界,其为 HALEU、TRISO 燃料的钠热管冷却微堆)、Valar Atomics 的 Ward 250 堆(6 月 18 日在犹他州 Emery 县 San Rafael 能源实验室临界,其为 TRISO 燃料模块化高温气冷堆 HTGR、使用氦冷却剂)之后。

临界是核裂变链式反应变为自持的点。零功率临界是一种低功率物理演示,堆芯达到受控、自持的链式反应,但不产生有意义的热输出或电力。Deployable 周三表示,Unity"在爱达荷国家实验室协作下、在适用法规要求下,经全面测试与启动程序,安全且按计划地"实现了临界。

据 DOE,该里程碑标志着其"履行了一项开创性的指令,以重燃美国核能创新",该指令来自第 14301 号行政命令(EO)。2025 年 5 月的命令要求 DOE:第一,加快 DOE 拥有或控制设施内的合格试验堆;第二,在 DOE 权限下建立"国家实验室之外的反应堆建造与运行试点计划",目标是 2026 年 7 月 4 日前批准至少三座反应堆实现临界。

周三,DOE 表示这三个里程碑使美国成为"史上首个在单月内于三种独特先进微堆设计上实现临界的国家"。

Unity 的赌注:类 CANDU 几何,却无 CANDU 供应链负担

总部位于休斯敦的 Deployable Energy 正在开发 Unity 作为 1-MWe 级微堆平台,用于表后(behind-the-meter)供电应用,包括国家安全设施、数据中心、海上用途、偏远工业场址和工艺热。在 6 月 24 日 INL 主办的参观中,公司官员将 Unity 描述为一座水慢化、气冷微堆,使用 4.95% 富集低浓缩铀(LEU)二氧化铀(UO2)燃料、氦冷却剂和商用现成材料,而非高丰度低浓缩铀、石墨慢化、热管或更专业的先进反应堆供应链。

INL 的试验堆采用 calandria 式(排管式)水慢化几何,但正如 Deployable 联合创始人兼首席商务官 Sanjay Mukhi 告诉 POWER,该设计与 CANDU 知识产权无关、彼此独立。公司官员更广泛地将试验堆描述为轻水堆(LWR)、HTGR 和 calandria 设计特征的结合。水提供慢化,氦移除热量,标准 LEU UO2 燃料使系统更贴近现有商业燃料基础设施。

虽然 Deployable 早期概念更像一个传统先进微堆——HALEU 燃料、石墨慢化、热管基础——但 Mukhi 表示 Deployable 得出结论:那将过于昂贵且受燃料与供应链可用性制约。Mukhi 这样总结设计哲学:"让我们使用现成可得的东西,"他说,"不要用异国材料,不要用难以制造的东西。让我们用轻松能搞到手的东西。"他补充道,挑战在于在使用商用材料和制造路线时保持安全和性能。

150 天交付

Deployable 是 2026 年 4 月公布的"核能发射台"计划四家入选者之一,年初开始与 INL 合作,从项目启动到交付反应堆、交付燃料并具备临界准备,仅用了惊人的约 150 天,投资为"个位数百万"美元,CEO 兼联合创始人 Bobby Gallagher 在临界里程碑后发布的视频中说。

进度是演示的一部分,Gallagher 周三指出。"Deployable 故事如此非凡之处在于我们如何达成这一里程碑。是执行的速度,"他说,并指出公司的快速进展建立在三大支柱上:其技术架构(使用现有材料和低浓缩铀以及可批量制造的工艺);供应链可得性(由跨供应商和国家实验室的"非凡合作"支撑);以及从研究、商业和海军反应堆界汲取的、经验丰富的团队。

Gallagher 还指出,INL 攻坚得到 100 多名经验丰富的 INL 员工、美国 DOE 核能办公室,以及 DOE 核反应堆副助理部长 Rian Bahran 博士和爱达荷运营办公室 DOE 经理 Bob Boston 等"拥护者"的支持。核管会(NRC)也"见证"了这一过程。快速部署将为 Deployable 的商业雄心提供信息——其目标是向客户现场交付系统,并在"不到六个月内"实现快速供电,他指出。

正如 Deployable 联合创始人兼首席运营官 Lance Maul 在 6 月 24 日参观中解释,Unity 的临界路径围绕渐进式装料攻坚展开。团队不是直接跳到完整构型,而是以小步增加反应性,在每个阶段测量响应,并在继续之前反复将系统返回到舒适的次临界状态。

INL 的现有基础设施对快速进度也至关重要。Mukhi 说 Unity 的小尺寸使团队能使用现有设施而非新建测试结构,并指出 INL 人员告诉公司该反应堆"能穿过门"。测试安装在 INL 北束站一个现有的中子射线照相空间内,那里已有厚屏蔽、可移动屏蔽塞和深地板坑。Mukhi 说该布置与公司预期商用构型的核心尺寸约 1:1。

Deployable 的下一步瞄准商业化路径

对 Deployable 而言,Unity 示范堆成功实现临界如今"标志着测试与演示下一阶段的开始,Deployable Energy 正迈向商业部署"。Gallagher 周三指出,公司希望在 2028 年前从 Unity 测试迈向商用反应堆,并最终服务美国能源需求,"从兆瓦级部署到吉瓦级部署"。

正如 POWER 在 DOE 公布首批发射台开发商时所报道,Deployable 正在开发 Unity Nuclear Battery(UNB,统一核电池)作为 1-MWe 气冷微堆,带主动冷却氦一次回路和标准 LEU UO2 燃料,为工厂制造而设计,可装入标准 20 英尺集装箱运输,用于偏远、分布式、海上和国防应用。Mukhi 告诉 POWER,公司运营一座位于休斯敦 58 英亩厂区的 340,000 平方英尺制造厂,有卡车通道、铁路支线和机械、制造、涂装、喷砂车间,并称该设施旨在支撑 Unity 机组的高产量生产。

同时,由于 NRC 一直在观察 DOE 授权过程,Deployable 期望在未来的取证案例中使用测试结果和流程,Mukhi 说。Deployable 表示自 2025 年 10 月以来一直参与 NRC 预申请活动,并 outlined 了一项战略:从 10 CFR Part 50 Class 103 非动力生产利用设施开始,并可能利用 NRC 新提议的 Part 57 框架,用于具有可比风险特征的微堆快速、高产量部署。

核能发射台的首次关键突破

Deployable 的临界实验里程碑是"核能发射台"计划下首个完成的,该计划由 DOE 于 2026 年 3 月启动,以补充 NRIC 的试验台,并接替两个寿命较短的 DOE 计划——2025 年 6 月启动的反应堆试点计划和 2025 年 7 月启动的燃料线试点计划。

正如 POWER 报道,核能发射台计划旨在为联邦和非联邦土地上的反应堆、燃料循环项目和配套核基础设施提供"更广泛、更灵活的部署路径"。该计划有两个分支:Launch Pad INL(提供 INL 约 2,000 英亩使用权)和 Launch Pad USA(可支持其他 DOE 场址、国家实验室和非联邦地点)。DOE 于 2026 年 6 月向申请者开放发射台和 DOME 试验台,设定 7 月 8 日初步提交截止期和后续定期审查,同时明确参与者将承担项目成本,包括设计、建造、运行、退役、DOE 授权和实验室参与费用。

然而重要的是,2025 年 5 月 23 日签署的第 14301 号行政命令(EO)指示 DOE 加快 DOE 拥有或控制设施内的合格试验堆,并另行建立"国家实验室之外的反应堆建造与运行试点计划",目标是 2026 年 7 月 4 日前批准至少三座反应堆实现临界。

在反应堆试点计划下,DOE 接受了来自 10 家公司的 11 个项目:Aalo Atomics、Antares Nuclear、Atomic Alchemy、Deep Fission、Last Energy、Natura Resources LLC、Oklo(入选两个项目)、Radiant Industries、Terrestrial Energy 和 Valar Atomics。其中,Antares 和 Valar 迄今已实现临界。

本周,正如公司官员告诉 POWER,"数日内"且在 7 月 4 日截止期前,Aalo Atomics 准备在其两英亩 INL 厂区的临界试验堆(CTR,代号"第一缕光计划")实现临界。

正如 Aalo CEO 兼联合创始人 Matt Loszak 在 6 月 24 日参观中透露,这座钠冷、石墨慢化、LEU UO2 燃料的热谱试验堆在现场工作开始后 36 天建成,随后装备了在 Aalo 奥斯汀工厂制造并经标准公路运往爱达荷的模块。该试验堆在几何、燃料量、石墨库存和控制棒机构上是全尺寸的,但初始临界攻坚不含钠冷却剂。

与此同时,周三 Oklo 表示 DOE 已批准 Oklo Isotopes(前称 Atomic Alchemy)在得州的 Groves 同位素试验堆的文件化安全分析(DSA)。此举使该私有土地项目进入 DOE 反应堆试点计划下的最终启动前审查过程。Oklo 表示目标在 2026 年 7 月实现 Groves 首次临界,但该里程碑可能推迟过 7 月 4 日截止期。

Groves 不同于 Oklo 更大的 Aurora-INL 项目(也属反应堆试点计划)。75-MWe 的 Aurora-INL 项目是一座钠冷快堆核电站,正在 INL 建造,Oklo 计划 2028 年开始商业运行。

Oklo 将 Groves 描述为一座零功率、单堆机组的未来多堆同位素生产设施,旨在让公司获得在国家实验室系统之外设计、建造、启动和运行具有商业相关性的核设施的经验。公司表示 Groves 将帮助开发运行程序、评估反应堆系统性能、验证同位素生产工艺,并支撑未来用于医疗、工业、科研、太空和国家安全的关键同位素国内生产。

"随着初步和文件化安全分析均获批准,Groves 现已进入启动前的最后阶段,包括就绪审查、装料和临界,"Oklo 联合创始人兼 CEO Jacob DeWitte 说,"破土不到一年,Groves 正迈向临界,并证明先进核能可以从业开阔野地、以商业时间表、凭借具有商业代表性的设施走向部署。DOE 展示了非凡的能力,能在这一时间尺度上为该类设施、且为国家实验室之外的设施审查和达成这一里程碑。作为 DOE 反应堆试点计划下首个达成此里程碑的此类项目,Groves 为美国如何加速先进反应堆部署、同时保持严格而务实的安全流程提供了蓝图。"

NRC Proposes Landmark Reactor Licensing Overhaul, Bundling Decades of Modernization Into One Rule

The Nuclear Regulatory Commission (NRC) has proposed what may be its most consequential reactor-licensing overhaul in a generation, a 553-page rulemaking that seeks to rewrite core pieces of the regulatory framework governing how commercial nuclear plants are sited, licensed, built, modified, operated, renewed, fueled, and ultimately decommissioned.

Issued July 1, the proposed rule, "Modernizing Reactor Licensing, Safety Oversight, and Siting Practices," (Docket ID NRC-2025-0975 and RIN 3150-AL44) reaches across 10 CFR Parts 2, 50, 51, 52, 53, 54, 71, and 100. Rather than advancing a single licensing reform, the NRC moved to bundle 17 distinct modernization measures into one package, targeting everything from the legal definition of "construction" to emergency preparedness, quality assurance, siting criteria, license renewal terms, advanced fuel deployment, and the use of risk-informed alternatives to long-standing prescriptive requirements.

The proposal is the NRC's most visible implementation step to date under Executive Order 14300, "Ordering the Reform of the Nuclear Regulatory Commission," issued in May 2025, which directed the agency to undertake a "wholesale revision" of its regulations and guidance.

In the proposed rule, the NRC says the changes are intended to modernize Part 50, the traditional two-step construction permit and operating license framework, and Part 52, the combined-license, design-certification, and early-site-permit framework, conform NRC regimes to Part 53, the new risk-informed, technology-inclusive framework for commercial nuclear plants, and support "additional generation to the electrical grid."

The agency also tied the package to the ADVANCE Act's direction to support increased availability of, and innovation in, nuclear power for economic and national security purposes. "NRC's regulations have not kept pace with new technologies and our energy needs," said NRC Chairman Ho Nieh, adding that the proposal would "strip out rigid frameworks and unnecessary conservatism" while accelerating safe deployment of new reactors and expansion of existing capacity.

On a July 1 media call, Nieh signaled an aggressive schedule for finalizing the proposed rule. In response to a POWER question about timing, he said the NRC is targeting commission review of a final reactor licensing modernization rule "around the end of this year or perhaps early next year." Nieh stressed that the proposal is intended to create optional regulatory pathways rather than force applicants into a single model. "The name of the game right now is optionality," he said. He also said the agency does not intend to "force fit new technologies into licensing frameworks that are no longer fit for purpose," calling exemptions "inefficient," "not predictable," and "not clear."

Nieh acknowledged that the value of the reforms will depend on NRC's execution. "What we don't want to happen," he said, is for "risk-informed, beneficial, safe programs" to be available but difficult to use in practice, which could discourage later applicants.

Separately, the NRC on July 1 proposed a radiation protection rule that would strip ALARA—its long-standing "as low as is reasonably achievable" standard—from the regulations and replace it with a graded, dose-based framework that leans on explicit numerical limits, multi-year exposure caps, and defined reporting thresholds.

A Striking Breadth of Reactor Licensing Changes

The proposed Modernizing Reactor Licensing rule follows several significant rules proposed or finalized over the past year. The rule's scope directly aligns with EO 14300's most specific reactor-licensing directives: tightening the circumstances under which the NRC may require reactor design changes once construction is underway; replacing qualitative safety tests with determinate, data-backed thresholds focused on "credible, realistic risks"; and revisiting how long renewed licenses can run in light of operating experience and aging-management data.

But the NRC staff also used the EO-driven review to bundle a broader set of process changes into the proposal. Those measures range from expanded use of risk-informed alternatives to prescriptive requirements to more flexible siting, emergency preparedness, decommissioning funding, and fuel-related provisions.

Core Licensing Architecture and Change Control

Setting Clearer Rules for Design Changes Once Construction Starts. The NRC would revise Parts 52 and 53 to address both NRC-directed and licensee-requested design changes during construction and operation. In response to EO 14300 Section 5(f), the agency proposes to "raise the threshold for changes required during construction" by eliminating "increased standardization" as a criterion for commission-directed modification of design certification information. The NRC also proposes to define and clarify categories of design information, including Tier 1, Tier 2, and Tier 2* information under Part 52. For licensee-requested changes, the NRC would provide greater flexibility for certain departures from Tier 1 design description information without requiring an exemption, provided specified criteria are met.

The NRC cites construction experience from Vogtle Units 3 and 4, suggesting that some Tier 1 change requests "may not have been important to safety," and that added flexibility could "reduce burden on licensees and minimize possible construction delays due to licensing reviews without impacting safety."

Safety Assessments Focused on Credible, Data-Backed Events. The NRC would add definitions for "design basis event" and "beyond design basis event" to 10 CFR 50.2. Defining beyond design basis events would support "graded regulatory treatment" for events that require attention but do not warrant mitigation exclusively through safety-related SSCs or conservative safety assessments.

Giving Applicants a Path Around One-Size-Fits-All Criteria. The NRC would add new voluntary provisions in 10 CFR 50.220 and 10 CFR 52.220, allowing applicants and licensees to propose technology-inclusive, risk-informed, or performance-based alternatives to existing prescriptive acceptance criteria.

Letting Licensees Make More Low-Risk Changes Without Prior NRC Approval. The NRC would create an optional pathway for licensees to use probabilistic risk assessment results in 10 CFR 50.59 reviews. The proposal would allow risk metrics such as core damage frequency and large early release frequency, along with defense-in-depth and safety-margin considerations, to show that a change does not result in a "more than minimal increase" in accident likelihood or consequences.

New Reactor Deployment and Project Execution

Earlier Construction Starts for Safety-Bounded Work. The NRC seeks to revise the definition of "construction" in 10 CFR 50.10 to focus pre-license construction controls on structures, systems, and components (SSCs) whose installation could affect their ability to perform a safety-significant function.

Less Prescriptive Construction Permit Applications. The NRC would revise 10 CFR 50.34 to better tie the level of detail in a preliminary safety analysis report to the findings the agency must make before issuing a construction permit. It would remove prescriptive light-water reactor language and replace parts of the rule with more "technology-inclusive" language.

More Durable Early Site Permits. The NRC also moved to remove the fixed expiration date for early site permits (ESPs), which currently can run no longer than 20 years. The proposal would allow a permit holder to keep a site "banked" indefinitely, while limiting the finality of time-sensitive safety and environmental information to 20 years unless the holder updates the ESP through an amendment.

Longer Manufacturing License Terms for Factory-Built Reactors. The NRC would extend the maximum initial and renewed term of a manufacturing license from 15 years to 40 years, while keeping the five-year minimum term. The provision appears aimed at microreactors, small modular reactors, and other deployment models that may rely on factory fabrication and repeated production.

Operational Programs Can Be Reviewed Earlier, but Not Always Up Front. The NRC would allow manufacturing license applicants under Parts 52 and 53 to submit "essentially complete" operational program information with the manufacturing license application. The provision is designed to "enhance regulatory certainty and expedite review timelines" without making early program submittal mandatory.

A Modern QA Option for Repeat Reactor Builds. The NRC would add a voluntary Appendix T to Part 50 as an alternative to Appendix B, the quality assurance framework in place since 1970. The new option would establish performance-based quality assurance criteria using a graded approach tied to the safety and risk significance of structures, systems, and components.

Fleet, Siting, Fuel, and Long-Term Operations

Extending Renewal Terms and Trimming Application Burdens. The NRC would revise Part 54 to allow renewed operating licenses to run for up to 40 years, rather than the current 20-year renewal term. The proposal would also allow applicants to voluntarily use risk-informed and performance-based alternatives in aging management reviews, remove the 20-year limit on how early a renewal application may be submitted, and eliminate several application and recordkeeping requirements.

Scaling Emergency Planning to Reactor Risk. The NRC would expand the performance-based emergency preparedness framework in 10 CFR 50.160 so it could be used by all reactor applicants and licensees, not only small modular reactors, non-light-water reactors, and certain non-power facilities. The agency would retain the core requirement for reasonable assurance that adequate protective measures can and will be taken in a radiological emergency.

Scaling Siting Reviews to Reactor Risk. The NRC would revise Part 100 reactor siting criteria to better account for differences in reactor type, size, output, source term, and potential radiological consequences. The proposal would create a tiered framework: lower-consequence "Tier 1" power reactors, including some non-stationary reactors, could use a revised and less prescriptive Subpart A, while "Tier 2" reactors would remain under Subpart B.

Creating a Path for Higher-Enriched LWR Fuel. The NRC would amend several regulations to support licensing of conventional and accident-tolerant light-water reactor fuel enriched above 5.0 weight percent uranium-235, in most cases without exemptions. The proposal would address criticality accident requirements, uranium fuel cycle environmental tables, transportation impacts, fissile material packaging, and emergency core cooling system acceptance criteria.

Right-Sizing Decommissioning Funding for Smaller Reactors. The NRC would amend 10 CFR 50.75 to let certain new reactor applicants and licensees use a design-specific decommissioning cost estimate instead of the existing minimum funding "formula" amount.

Targeted Standards and Cleanup Changes

Updating Codes-and-Standards Flexibility. The NRC would make two targeted changes to modernize how incorporated standards are handled. First, it would delete an outdated footnote in 10 CFR 50.49 linking "safety-related" electrical equipment to "Class 1E." Second, it would broaden 10 CFR 50.55a(z) so applicants and licensees could request alternatives to any regulatory requirement in 10 CFR 50.55a. The NRC says the changes would "improve regulatory clarity," avoid "unanticipated exemptions," and provide "additional flexibility" without changing the underlying safety standard.

NRC 提出里程碑式反应堆许可改革,将数十年现代化整合为单一规则

美国核管会(NRC)提出了一项可能是其一代人以来影响最深远的反应堆许可改革——一份 553 页的规则制定提案,旨在重写监管框架的核心部分,该框架规定了商用核电站如何选址、取证、建造、改造、运行、续证、装料,并最终退役。

于 7 月 1 日发布的拟议规则《现代化反应堆许可、安全监督和选址实践》(案卷号 NRC-2025-0975,RIN 3150-AL44)跨越 10 CFR 第 2、50、51、52、53、54、71 和 100 部分。NRC 没有推进单一许可改革,而是将 17 项独立的现代化措施打包为一个整体方案,目标涵盖从"建造"的法律定义,到应急准备、质量保证、选址标准、许可证续期条款、先进燃料部署,以及用风险告知替代方案取代长期的规定性要求。

该提案是 NRC 在 2025 年 5 月发布的第 14300 号行政命令《命令改革核管会》下迄今最可见的实施步骤,该命令要求 NRC 对其法规和导则进行"全面修订"。

在拟议规则中,NRC 表示这些变更旨在现代化第 50 部分(传统的两步式建造许可与运行执照框架)和第 52 部分(联合执照、设计认证和早期场址许可框架),使 NRC 制度与第 53 部分(商用核电站新的风险告知、技术包容框架)保持一致,并支撑"电网新增发电能力"。

NRC 还将该方案与《ADVANCE 法案》的方向挂钩,以支持出于经济和国家安全目的增加核能可用性与创新。"NRC 的法规未能跟上新技术和我们的能源需求,"NRC 主席 Ho Nieh 说,并补充该提案将"剥离僵化框架和不必要的保守主义",同时加速新反应堆的安全部署和现有产能的扩张。

在 7 月 1 日的媒体电话会上,Nieh 给出了完成拟议规则的激进时间表。在回答 POWER 关于时点的提问时,他表示 NRC 的目标是在"今年年底或明年初左右"完成最终反应堆许可现代化规则的委员会审查。Nieh 强调该提案旨在创建可选的监管路径,而非强迫申请者套用单一模式。"当前游戏的名字是'可选性',"他说。他还表示 NRC 不打算"将新技术强行塞入不再适用的许可框架",称豁免是"低效的"、"不可预测的"和"不清晰的"。

Nieh 承认改革的价值取决于 NRC 的执行。"我们不想看到的情况是,"他说,存在"风险告知、有益、安全的方案"却在实践中难以使用,这可能打消后续申请者的积极性。

此外,NRC 于 7 月 1 日提出了一项辐射防护规则,将从法规中剥离 ALARA——其长期以来的"合理可行尽量低"(as low as is reasonably achievable)标准——并以分级的、基于剂量的框架取而代之,该框架依赖明确的数值限值、多年暴露上限和定义的报告阈值。

反应堆许可变革的惊人广度

拟议的《现代化反应堆许可》规则承接过去一年提出或 finalized 的几项重要规则。该规则的范围与 EO 14300 最具体的反应堆许可指令直接一致:收紧 NRC 在建造进行中可要求反应堆设计变更的情形;用聚焦于"可信、现实风险"的确定性、数据支撑阈值取代定性安全试验;并根据运行经验和老化管理数据重新审视续期许可证的时长。

但 NRC 员工也利用 EO 驱动的审查,将更广泛的流程变更打包进提案。这些措施从扩大风险告知替代方案在规定性要求中的使用,到更灵活的选址、应急准备、退役资金和燃料相关条款。

核心许可架构与变更控制

为建造开始后的设计变更设定更清晰的规则。NRC 将修订第 52 和 53 部分,以处理建造和运行期间 NRC 指令性和持证人请求的两种设计变更。为回应 EO 14300 第 5(f) 条,NRC 提议"提高建造期间所需变更的门槛",取消将"增加标准化"作为委员会指令性修改设计认证信息的标准。NRC 还提议定义并澄清设计信息类别,包括第 52 部分下的 Tier 1、Tier 2 和 Tier 2* 信息。对于持证人请求的变更,在满足特定标准的前提下,NRC 将给予更大灵活性,允许某些偏离 Tier 1 设计描述信息而无需豁免。

NRC 援引 Vogtle 3、4 号机的建造经验,认为某些 Tier 1 变更请求"可能对安全并不重要",增加的灵活性可"减轻持证人负担,并在不影响安全的情况下,最小化因许可审查可能导致的建造延误"。

聚焦可信、数据支撑事件的安全评估。NRC 将在 10 CFR 50.2 中增加"设计基准事件"和"超设计基准事件"的定义。定义超设计基准事件将支持对需要关注但不值得仅通过安全相关 SSC 或保守安全评估来缓解的事件的"分级监管处理"。

给申请者绕过"一刀切"标准的路径。NRC 将在 10 CFR 50.220 和 52.220 中增加新的自愿条款,允许申请者和持证人提出技术包容、风险告知或基于性能的替代方案,取代现有的规定性验收准则。

让持证人可在无事先 NRC 批准下做更多低风险变更。NRC 将创建一条可选路径,允许持证人在 10 CFR 50.59 审查中使用概率风险评价结果。该提案将允许堆芯损坏频率和大早期释放频率等风险指标,结合纵深防御和安全裕度考量,证明某变更不会导致事故可能性或后果"超过最小增加"。

新反应堆部署与项目执行

安全边界内工作的更早开工。NRC 寻求修订 10 CFR 50.10 中"建造"的定义,将许可前建造控制聚焦于其安装可能影响其执行安全重要功能能力的结构、系统和部件(SSC)。

更少规定性的建造许可申请。NRC 将修订 10 CFR 50.34,使初步安全分析报告中的技术细节水平更好地与发证前 NRC 必须作出的结论挂钩。它将删除规定性的轻水堆语言,并以更"技术包容"的语言替换部分规则。

更持久的 early site permits(早期场址许可)。NRC 还着手取消早期场址许可(ESP)的固定到期日——目前 ESP 最长 20 年。提案将允许持证人无限期"储存"场址,同时将时效性安全与环境信息的最终性限制在 20 年,除非持证人通过修订更新 ESP。

工厂建造反应堆更长的制造许可证期限。NRC 将制造许可证的初始和续期最长期限从 15 年延长至 40 年,同时保持 5 年最短期限。该条款似乎针对微堆、小型模块化反应堆和其他可能依赖工厂制造和重复生产的部署模式。

运行程序可更早审查,但不总在前端。NRC 将允许第 52 和 53 部分下的制造许可证申请者在申请时提交"基本完整"的运行程序信息。该条款旨在"增强监管确定性并加快审查时间线",而非强制早期提交。

重复建造反应堆的现代 QA 选项。NRC 将在第 50 部分增加自愿的附录 T,作为自 1970 年起实施的附录 B(质量保证框架)的替代。新选项将建立基于性能的 QA 准则,采用与结构、系统和部件的安全与风险重要性挂钩的分级方法。

机组群、选址、燃料与长期运行

延长续期期限并削减申请负担。NRC 将修订第 54 部分,允许续期的运行许可证运行长达 40 年,而非当前的 20 年续期条款。提案还将允许申请者在老化管理审查中自愿使用风险告知和基于性能的替代方案,取消续期申请可提前提交不得超过 20 年的限制,并取消若干申请和记录保存要求。

按反应堆风险缩放应急计划。NRC 将扩大 10 CFR 50.160 中基于性能的应急准备框架,使其可供所有反应堆申请者和持证人使用,而非仅小型模块化反应堆、非轻水堆和某些非动力设施。NRC 将保留核心要求:合理保证在放射性紧急情况下能够且将采取适当防护措施。

按反应堆风险缩放选址审查。NRC 将修订第 100 部分反应堆选址标准,以更好考虑反应堆类型、规模、输出、源项和潜在放射性后果的差异。提案将创建分级框架:后果较低的"Tier 1"动力反应堆(包括某些非固定反应堆)可使用修订后更少规定性的 Subpart A,而"Tier 2"反应堆仍留在 Subpart B。

为高富集度 LWR 燃料开辟路径。NRC 将修订若干法规,以支持富集度超过 5.0 重量百分比铀-235 的传统和事故容错轻水堆燃料取证,多数情况下无需豁免。提案将处理临界事故要求、铀燃料循环环境表、运输影响、易裂变材料包装和应急堆芯冷却系统验收准则。

Google Invests in $468-Million Funding Round for German Fusion Group

Proxima Fusion, a Munich, Germany-based group that is considered among the leading European companies working on fusion energy, said it completed a €411 million ($468 million) funding round. Proxima on July 7 said investors included technology giant Google along with global energy company RWE.

Proxima on Tuesday said the latest funding, which was led by XTX Ventures and East X Ventures, brings the company's valuation to €2.4 billion ($2.7 billion) and establishes it as the best-financed fusion company in Europe. Proxima was founded in April 2023, and spun out of the well-known Max Planck Institute for Plasma Physics. The company develops Quasi-Isodynamic (QI) stellarators, a type of magnetic confinement reactor, that builds on decades of research from the Wendelstein 7-X program.

RWE's investment of €25 million ($28.6 million) comes a few months after the German energy company signed a partnership agreement with Proxima to build a stellarator fusion power plant at the site of a former nuclear fission power plant in Gundremmingen, Bavaria. Google's investment continues that company's interest in fusion and nuclear energy in general as a source of long-term carbon-free energy.

"Thanks to strong research and innovative start-ups such as Proxima Fusion, Germany can become a key player in nuclear fusion," said Dr. Markus Krebber, CEO of RWE AG. "It is now crucial that the federal and state governments shape the framework conditions in such a way as to specifically accelerate the development towards a commercial fusion reactor in Germany. RWE is contributing to this by investing in both magnetic and laser fusion companies and by making available our decommissioning sites, with their existing nuclear infrastructure, and our expertise in regulatory approvals. In doing so, we are creating significant time and cost advantages in the international race for fusion."

Proxima said the financing is part of the support needed to build what it calls Alpha, the company's net-energy stellarator demonstrator near Munich, Germany. Alpha is being developed by Proxima in partnership with the state of Bavaria, the Max Planck Institute for Plasma Physics, and RWE.

"Europe is racing with the United States and China to get to the first fusion power plant," said Dr. Francesco Sciortino, co-founder and CEO of Proxima Fusion. "Proxima's financing demonstrates that Europe can not only invent breakthrough technologies, but also build globally competitive companies around them. Investors recognize both the urgency and the opportunity of what we're doing and are backing us to develop a generational energy technology company."

Secured Funding

Proxima said it has secured more than €650 million ($740 million), including €95 million ($108 million) in public grants, since its founding in 2023. The company said the funding announced Tuesday exceeded its target of matching Bavaria's commitment for a €400 million ($457 million) public funding contribution to the company's strategy. Proxima said the financing will put its focus on completion of the Stellarator Model Coil, expansion of high-temperature superconducting (HTS) cable and magnet production, and continued development of the engineering and manufacturing systems required for stellarators. Proxima said it will hire workers across engineering, manufacturing and operations to accelerate progress.

Proxima has said it is targeting completion of Alpha in the early 2030s, which would support the company's plan for its first commercial stellarator fusion power plant, called Stellaris, later that decade.

Google has said its support of Proxima is among a series of fusion-focused investments by the company as it looks for ways to power its energy-intensive data center and AI infrastructure operations. The company has said it has a goal to run its operations totally on carbon-free energy.

Other investors in the latest funding for Proxima include KfW Capital, SPRIND, and Burda Principal Investments. Returning investors include Plural, UVC Partners, Balderton, Cherry Ventures, DST Global Partners, Brevan Howard Macro Venture, Lightspeed, DTCF, redalpine, Leitmotif, Elaia, CDP Venture Capital, Bayern Kapital, and the EIC Fund.

"得益于强大的研究和 Proxima Fusion 等创新型初创企业,德国能成为核聚变的关键参与者,"RWE AG 首席执行官 Markus Krebber 博士说,"现在关键是联邦和州政府塑造框架条件,以专门加速德国迈向商用聚变反应堆的发展。RWE 通过投资磁约束和激光聚变公司、并提供我们带有现有核基础设施的退役场址以及我们在监管审批方面的专业知识,为此作出贡献。在此过程中,我们在国际聚变竞赛中创造了显著的时间和成本优势。"

Proxima 表示,该融资是其建造所谓 Alpha(公司位于德国慕尼黑附近、净能量仿星器演示装置)所需支持的一部分。Alpha 由 Proxima 与巴伐利亚州、马克斯·普朗克等离子体物理研究所和 RWE 合作开发。

"欧洲正与美国和中国赛跑,争夺第一座聚变电厂,"Proxima Fusion 联合创始人兼 CEO Francesco Sciortino 博士说,"Proxima 的融资证明欧洲不仅能发明突破性技术,还能围绕它们建立全球竞争力公司。投资者认识到我们所做之事的紧迫性和机遇,并支持我们发展一家世代级能源技术公司。"

已锁定资金

Proxima 表示,自 2023 年成立以来已锁定超过 6.5 亿欧元(7.4 亿美元),其中包括 9500 万欧元(1.08 亿美元)公共赠款。公司表示周二公布的融资超出了其与巴伐利亚州对等的 4 亿欧元(4.57 亿美元)公共资金贡献承诺的目标。Proxima 表示融资将使其重点放在完成仿星器模型线圈、扩大高温超导(HTS)电缆和磁体生产,以及持续发展仿星器所需的工程和制造系统。Proxima 表示将在工程、制造和运营领域招聘员工以加速进展。

Proxima 曾表示目标在 2030 年代初完成 Alpha,这将支撑公司在该十年后期首座商用仿星器聚变电厂(名为 Stellaris)的计划。

Google 表示对 Proxima 的支持是该公司一系列聚焦聚变的投融资之一,因其正寻找方式为高能耗数据中心和 AI 基础设施运营供电。公司表示其目标是完全以无碳能源运行其运营。

Proxima 最新融资的其他投资者包括 KfW Capital、SPRIND 和 Burda Principal Investments。回归投资者包括 Plural、UVC Partners、Balderton、Cherry Ventures、DST Global Partners、Brevan Howard Macro Venture、Lightspeed、DTCF、redalpine、Leitmotif、Elaia、CDP Venture Capital、Bayern Kapital 和 EIC Fund。

As demand for reliable, independent energy accelerates in the U.S., this investment enables Rolls-Royce to keep pace with the market and provide mission-critical backup power generation at a greater scale than ever before. Mankato plays an essential role in both the future of Rolls-Royce and U.S. manufacturing – the American-made generators built here power economic activity and critical infrastructure across the Americas.

The U.S. is undergoing a manufacturing renaissance, and Rolls-Royce is proud to be a part of that movement. This expansion in Mankato builds on our century-long commitment in America, investing locally to drive national economic growth.

Adam Wood, Managing Director at Rolls-Royce in America said:

Rolls-Royce has a deep history in Mankato, and we are proud to demonstrate our continued commitment to grow in and with this community. From the beginning, providing essential power systems for local farmers, to today, where we are producing large-scale generators that support critical infrastructure across the country, the impact of our Mankato facility is defined by the people who keep it running, generation after generation.

The new LOC provides additional capacity for logistics and assembly operations and was purpose built to support increased production of mtu Series 4000 generator sets. Approximately two-thirds of the Mankato LOC is dedicated to logistics operations, with the remaining space supporting production activities. The facility includes climate-controlled logistics and assembly areas, interior loading and unloading capabilities and room for future expansion as demand continues to grow.

Catalina Valencia, Executive Director of Business Development, Minnesota Department of Employment and Economic Development, said: Mankato is a hub for business and manufacturing, and we are very pleased to see a truly meaningful investment by Rolls-Royce in local jobs, industry, and community. This is about more than a new facility, it's about expanding our ecosystem of skilled trades, supply networks, and production capabilities – keeping Minnesota attractive and competitive for the future.

The generator sets produced in Mankato use mtu Series 4000 engines that are built at the Rolls-Royce facility in Aiken, South Carolina, where Rolls-Royce announced a $75M capital investment in July 2025.

The Mankato investment, first announced in June 2025, is expected to increase production capacity for mission-critical backup power systems by more than double by the end of 2026.

六、聚变能

68. 通用聚变(General Fusion)与 Spring Valley 合并获股东批准,拟登陆纳斯达克

英文原文

Spring Valley Acquisition Corp. III Shareholders Approve Business Combination with General Fusion

General Fusion expected to become the first publicly traded, pure-play fusion company. Combined company expected to begin trading on the Nasdaq under ticker symbol "GFUZ".

VANCOUVER, British Columbia – July 6, 2026 – Spring Valley Acquisition Corp. III ("Spring Valley" or "SVAC") (NASDAQ: SVAC) today announced that its shareholders have approved the previously announced business combination with General Fusion Inc. ("General Fusion" or the "Company"), a leader in the global race to commercialize fusion energy. General Fusion securityholders also voted to approve the transaction at a special meeting held on July 6, 2026. The approval represents another significant milestone toward completing the transaction and advancing General Fusion's uniquely practical Magnetized Target Fusion ("MTF") technology, which has the potential to deliver zero-carbon, baseload power in a cost-competitive way. This comes at a critical time as demand for electricity surges and nations around the world race to commercialize fusion power.

The closing of the transaction is expected to occur on or about Friday, July 10, 2026, subject to regulatory approvals and the satisfaction or waiver of all closing conditions. At the closing, Spring Valley will be renamed "General Fusion Group Ltd." Shortly thereafter, the combined company's shares and warrants are expected to trade on the Nasdaq under the ticker symbols "GFUZ" and "GFUZW," respectively, subject to approval of its listing application.

"The expected closing of this transaction represents a major step in the General Fusion journey, building on more than 20 years of technology development and leadership in the industry," said Greg Twinney, Chief Executive Officer of General Fusion. "Bringing fusion to the capital markets at this inflection point and becoming the first publicly traded pure-play fusion company marks an incredible next chapter for us as we advance on our path to commercialization and our mission to bring clean power from fusion to the grid."

"We're proud to support General Fusion at a pivotal moment for both the company and the fusion industry," said Chris Sorrells, Chairman and Chief Executive Officer of Spring Valley. "Global energy demand is rising, and the need for reliable, clean power has never been greater. General Fusion stands out with strong leadership, meaningful peer-reviewed results, a robust patent portfolio, and LM26, its operating fusion demonstration machine. The company's practical engineering approach offers a strong path to commercialization."

Quick Facts:

  • General Fusion's MTF is designed to solve significant barriers to commercializing fusion energy at a time when electricity demand is surging and nations around the world are racing to commercialize fusion power.

  • As a technology, MTF aims to achieve fusion in a practical way, avoiding superconducting magnets and high-powered lasers while enabling the use of existing materials for durable machines that would produce cost-effective energy.

  • In early 2025, General Fusion announced that it had designed, built, and begun operating its Lawson Machine 26 ("LM26") fusion demonstration machine in under two years. LM26 is the first MTF demonstration machine to be built at a commercially relevant scale. It mechanically compresses plasma with a lithium liner at 50% commercial-scale diameter, based on current design parameters.

  • LM26 aims to achieve key fusion technical milestones: plasma heating to 1 keV (10 million degrees Celsius), then 10 keV (100 million degrees Celsius), and ultimately the Lawson criterion, the combination of fusion parameters that can produce net fusion energy in the plasma.

七、核医学与辐射防护

71. 第二次 PSMA PET 扫描改变近半数前列腺癌患者治疗方案

英文原文

Second PSMA PET Changes Treatment for Nearly Half of Prostate Cancer Patients

Reston, VA (July 7, 2026) — A second PSMA PET scan changed treatment plans for nearly half of patients whose first scan was negative, according to new research published in the July issue of The Journal of Nuclear Medicine. Findings from the repeat PSMA scans, which included both local and distant disease, resulted in a change in management for nearly 50 percent of these patients.

Managing recurrent prostate cancer after first-line treatment, such as prostatectomy or radiation therapy, remains a clinical challenge. Although PSMA PET imaging has improved disease detection, 30 percent of patients still have no detectable disease on initial imaging, even as rising prostate-specific antigen (PSA) levels suggest recurrence. Few studies have examined whether repeating PSMA PET in this situation is worthwhile.

"There is little information on the utility of repeating a PSMA PET after an initial negative scan," said Ur Metser, BSc, MD, FRCPC, professor of radiology at the University of Toronto and head of the Division of Molecular Imaging at the Joint Department of Medical Imaging at Princess Margaret Cancer Centre in Toronto. "In our study, my colleagues and I sought to determine the benefit of a second PSMA PET scan, as well as to assess predictors for positive PSMA PET scans."

The study included 210 patients from the Registry for Recurrent Prostate Cancer in Ontario who had more than one PSMA PET scan and whose initial scan was negative. The scan positivity rate, serum PSA, PSA doubling time, and management change after the second scan were compared with baseline data. Disease distribution was classified as local recurrence, locoregional, oligometastatic (fewer than five positive disease sites), or extensive metastatic (more than five positive disease sites).

A second PSMA PET scan revealed evidence of disease in 56 percent of recurrent prostate cancer patients who had an initial negative PSMA PET scan. A management change was necessary for nearly 50 percent of patients, in particular those with oligometastatic disease. Researchers found that repeat imaging was most likely to detect disease in patients with higher PSA levels and a PSA doubling time of less than twelve months.

"The findings in this study further strengthen the pivotal role of PSMA PET in the management of men with recurrence of prostate cancer after first-line therapy," said Metser. "Understanding the extent of disease in patients who have initial negative PSMA PET scans provides valuable information for physicians as they create treatment plans."

第二次 PSMA PET 扫描改变近半数前列腺癌患者治疗方案

雷斯顿,弗吉尼亚州(2026 年 7 月 7 日)— 根据发表在《核医学杂志》7 月刊的新研究,在首次扫描为阴性的患者中,第二次 PSMA PET 扫描改变了近半数的治疗方案。重复 PSMA 扫描(包括局部和远处病变)的结果为近 50% 的此类患者带来了治疗策略的改变。

在一线治疗(如前列腺切除术或放疗)后管理复发性前列腺癌仍是临床挑战。尽管 PSMA PET 成像改善了疾病检出,仍有 30% 的患者在初次成像中无可检测病变,即便前列腺特异性抗原(PSA)水平升高提示复发。很少研究考察在这种情况下重复 PSMA PET 是否值得。

"关于在初始阴性扫描后重复 PSMA PET 的效用,信息很少,"多伦多大学放射学教授、多伦多 Princess Margaret 癌症中心联合医学影像部分子影像科主任 Ur Metser 医学博士说,"在我们的研究中,我和同事试图确定第二次 PSMA PET 扫描的益处,并评估阳性 PSMA PET 扫描的预测因素。"

该研究纳入了安大略省复发性前列腺癌登记库中 210 名接受超过一次 PSMA PET 扫描且初次扫描为阴性的患者。将第二次扫描后的扫描阳性率、血清 PSA、PSA 倍增时间和治疗变更与基线数据比较。疾病分布分为局部复发、区域淋巴结、寡转移(少于五个阳性病灶)或广泛转移(多于五个阳性病灶)。

第二次 PSMA PET 扫描在初次阴性扫描的复发性前列腺癌患者中揭示了 56% 的疾病证据。近 50% 的患者需要治疗变更,尤其是寡转移疾病患者。研究人员发现,重复成像最可能在 PSA 水平较高且 PSA 倍增时间少于 12 个月的患者中检出疾病。

"该研究的发现进一步强化了 PSMA PET 在一线治疗后复发前列腺癌男性管理中的关键作用,"Metser 说,"了解初次阴性 PSMA PET 扫描患者的疾病范围,为医生制定治疗方案提供了宝贵信息。"
