NuScale与斗山签合同,首件反应堆冷却系统上部组件投产
NuScale Power与斗山Enerbility签署合同,涉及77兆瓦模块反应堆冷却系统的上部组件。相关工作将在斗山韩国昌原工厂进入首件生产阶段,NuScale正为商业化部署做准备。

NuScale表示,合同涵盖在斗山昌原工厂继续制造反应堆冷却系统的关键上部组件。双方合作始于2019年,这几年里为NuScale通过美国核管理委员会(NRC)认证的技术开发了制造工艺、供应链和生产设施。协议在斗山总部举行的仪式上签署。
NuScale总裁兼首席执行官John Hopkins说:“这份协议是把我们已获批的设计转化为可交付模块的重要一步。”他说,斗山的核制造设施加上2019年以来的工作,让NuScale有能力和成熟的流程,按客户的时间表交付模块。斗山核业务集团首席执行官Jongdoo Kim说,这份合同标志着“从技术验证走向实际制造”。
设计获批与模块出力
NuScale称,其设计是唯一获得美国核管理委员会认证的小型模块化反应堆设计。NRC的批准针对的是反应堆设计。公司表示,工厂制造的组件可以运到建设现场。每个模块可发电77兆瓦,总热功率250兆瓦。NuScale最多可用12个模块组成一座电厂,总装机924兆瓦。
2026年9月1日,NuScale和MillenniTEK表示,双方已为被动式应急堆芯冷却系统造出首批氧化硼芯块。据NuScale介绍,这些芯块会溶入反应堆冷却剂,无需操作员干预就能把堆芯反应性控制在安全水平。
订单簿仍不具约束力
合同只涵盖一个组件,即反应堆冷却系统上部。在TVA项目中,NuScale没有完整模块的约束性订单。与NuScale相关的已公布美国项目里,最大的是TVA计划新增最多6吉瓦核电装机,约相当于72个77兆瓦模块。该计划背后的2025年9月协议由TVA与NuScale独家商业化合作伙伴ENTRA1 Energy签署,NuScale并非签约方。这份协议不具约束力。
按已公布的结构,ENTRA1将开发、融资、拥有和管理电厂,并在未来的购电协议下向TVA售电。NuScale供应反应堆技术。TVA和ENTRA1称,该计划可为约450万户家庭或60个新数据中心供电。NuScale和ENTRA1还共同持有一家名为ENTRA1 NuScale的合资企业,双方各占50%。
目前,随着项目达到里程碑,资金从NuScale流向ENTRA1。根据2025年8月签署的合作里程碑协议,NuScale为第一个里程碑计入50740万美元费用,其文件称这占总量的15%。其中24750万美元在2025年支付,25990万美元在2026年上半年支付。2026年上半年经营性现金流出达到37290万美元,上年同期为5610万美元。2026年第二季度收入为75000美元,低于上年同期的810万美元。
接下来会发生什么
NuScale表示,ENTRA1“仍在推进”与TVA的谈判,目标是达成最终的购电协议。协议签署之前,没有任何东西已经签约。斗山合同把反应堆冷却系统上部推进到首件生产阶段。NuScale称,这份协议增强了它随着客户项目推进、从设计认证走向模块交付的能力。
