技术简介

核电机组增容通过改造现役机组的汽轮机、蒸汽发生器及数字控制系统提高容量，而非新建电站。2
By modernizing and upgrading turbines, steam generators, and digital control systems at operating plants, uprates deliver substantial capacity gains without the multi-year timelines or interconnection bottlenecks associated with greenfield construction.

已有应用

西门子能源正在为伊利诺伊州Braidwood和Byron核电站增容提供新高压及低压蒸汽轮机。3
At the Braidwood and Byron Clean Energy Centers in Illinois, Siemens Energy is providing new low- and high-pressure steam turbines to increase their output.

为何此时

美国能源部于2026年3月启动UPRISE计划，以提高现役反应堆发电量来扩大核电容量。4
In March 2026, in accordance with the Executive Order, DOE launched its Utility Power Reactor Incremental Scaling Effort (UPRISE) to accelerate the expansion of the nation’s nuclear capacity by maximizing power generation from existing reactors.

主要参与者

星座能源与谷歌宣布合作为PJM电网增加890兆瓦核电容量。2
BALTIMORE and MOUNTAIN VIEW, Calif. — Oct. 6, 2026 — Google and Constellation Energy today announced a long-term strategic clean energy collaboration to bring 890 megawatts (MW) of new, reliable nuclear capacity onto the PJM Interconnection grid to meet growing demand and increase grid reliability.

未定事项

有条件贷款承诺仍需完成尽调、协商最终融资文件并满足适用条件。1
The conditional commitment is subject to the completion of due diligence, negotiation of definitive financing documents and satisfaction of applicable conditions.
