Just one week after inking a consortium agreement to partner on the design and construction of Poland’s first nuclear power plant, Westinghouse Electric Company and Bechtel joined state-owned Polish utility Polskie Elektrownie Jądrowe (PEJ) in Warsaw on Wednesday for the signing of the project’s engineering services contract.

China’s State Council recently approved the construction of four Westinghouse AP1000 reactors—two at China’s Sanmen plant in Zhejiang Province and two at the Haiyang plant in Shandong Province.

The plants currently house two AP1000 units each. Sanmen’s reactors are rated at 1,157 MWe and Haiyang’s at 1,170 MWe. Sanmen-1 and -2 began commercial operation in 2018. Haiyang-1 started commercial operation in 2018, and Haiyang-2 in 2019.
