The proposed construction of four 1250 MWe CAP1000 reactors (units 1-4) at the Lufeng site was approved by China’s National Development and Reform Commission in September 2014. However, the construction of units 1 and 2 did not receive State Council approval until 19 August 2024. The first safety-related concrete for the nuclear island of unit 1 was poured on 24 February last year, with that of unit 2 following in December. Approval for units 3 and 4 is still pending. The CAP1000 design is the Chinese version of the Westinghouse AP1000.

The construction of Hualong One reactors as units 5 and 6 at the Lufeng plant was approved by the State Council in April 2022. First concrete for unit 5 was poured on 8 September 2022, with that for unit 6 following on 26 August 2023. Units 5 and 6 are expected to be connected to the grid in 2028 and 2029, respectively.

According to China General Nuclear, once all six units are in operation, the Lufeng plant will generate about 52 TWh, which will reduce standard coal consumption by almost 16 million tonnes and reduce carbon dioxide emissions by more than 42 million tonnes.
