First Commercial AP1000, EPR Reactors Connected to Grid
Two nuclear energy milestones were reached in the past week, as the world’s first commercial AP1000 and EPR reactors were connected to China’s power grid.
Westinghouse announced Sanmen 1, the first AP1000 unit, was connected to the grid June 30, one day after Électricité de France (EDF) connected the first EPR reactor—Taishan 1—to the system. The EPR is a third-generation pressurized water reactor, with technology by EDF and France’s Framatome. Taishan 1 is the first of two, 1.7-GW reactors at the site, which is owned by TNPJVC, a joint venture of China General Nuclear (CGN), which owns 51%; EDF, which owns 30%; and Yuedian, a Chinese electric company that owns 19%.
The 1.1-GW Sanmen 1 reactor is the first of four new AP1000 plants under construction in eastern China. The AP1000, also a pressurized water reactor, is the technology being used for two new reactors at the Vogtle nuclear plant in Georgia. Unit 3 at Vogtle is scheduled to come online in November 2021, with Unit 4 following a year later.…
