During 2023, construction began on six PWR nuclear power reactors in China and Egypt with total capacity of 6.8 GW(e). China continued to lead the world’s nuclear power expansion by starting the construction of five reactors. These include four CAP1000 reactors: Haiyang-4 (1161 MW(e)), Lianjiang-1 (1224 MW(e)), Sanmen-4 (1163 MW(e)), and Xudapu-1 (1000 MW(e)). Additionally, construction began on one HPR1000 reactor, Lufeng-6 (1116 MW(e)). On 3 May, the first concrete was poured into the foundation, marking the start of the main construction phase for Unit 3 (a 1100 MW(e) VVER-1200 reactor) of the El Dabaa nuclear power plant project in Egypt.
