Rosatom, has shipped the reactor pressure vessel (RPV) and one of the four steam generators for Xudabu-4 nuclear power plant being built in Liaoning province in northeast China.

Construction of Xudabu-4 (also written in English as Xudabao and Xudapu) started in May 2022.

The plant will be a conventional pressurised water reactor unit using the Russian VVER-1200 technology.

The RPV is one of the largest reactor components at a nuclear plant. It is a vessel containing the nuclear reactor coolant, core shroud, and the reactor core and fuel.

The steam generators act as heat exchangers where water carrying heat generated from the nuclear reaction is used to turn demineralised water into steam for the plant turbines.

The Xudabu project was originally expected to comprise of six CAP1000 plants, with Units 1 and 2 in the first phase.

Site preparation began in November 2010, but plans changed with the construction of two VVER-1200 reactors for Units 3 and 4.

International Atomic Energy Agency data shows four units are currently under construction at Xudabu – Units 1 and 2 are CAP1000s, and Units 3 and 4 are VVER-1200s.
