Reactor pressure vessel delivered for Lianjiang 1
The reactor pressure vessel for unit 1 of the Lianjiang nuclear power plant has arrived at the construction site in China's Guangdong province. It will be the first of two CAP1000 reactors planned for the first phase of the plant.

The vessel - which will house the nuclear reactor and is the core of a nuclear power plant - was manufactured by Shanghai Electric Nuclear Power Group and was delivered to the Lianjiang site on 13 February.
"The successful delivery of the reactor pressure vessel of unit 1 marked the beginning of the transition of the long-cycle main equipment of the Lianjiang Nuclear Power Phase I project from the manufacturing stage to the delivery stage, and marked that unit 1 has entered a new stage of cross-continuity of civil engineering and installation from the civil engineering stage," State Power Investment Corp (SPIC) said
The construction of the first two 1250 MWe CAP1000 reactors - the Chinese version of the Westinghouse AP1000 - at the Lianjiang site was approved by China's State Council in September 2022. Excavation works for the units began in the same month, with the pouring of first concrete for the foundation of unit 1 starting in September 2023 and that of unit 2 in April last year. Lianjiang unit 1 is expected to be completed and put into operation in 2028.
Once all six CAP1000 units planned at the site are completed, the annual power generation will be about 70.2 TWh, which will reduce standard coal consumption by more than 20 million tonnes, and reduce carbon dioxide emissions by more than 52 million tonnes, sulphur dioxide by about 171,000 tonnes and nitrogen oxides by about 149,000 tonnes.
SPIC says the Lianjiang plant will be the first nuclear power project in China to adopt seawater secondary circulation cooling technology as well as the first to use a super-large cooling tower.
