Russia’s nuclear equipment manufacturer Atommash has shipped three of the four steam generators for Unit 4 of the Xudabu nuclear power station being built in Liaoning province in northeast China.

Atommash, part of Russian state nuclear corporation Rosatom, shipped the first of the four steam generators and the reactor pressure vessel in August 2024.

Construction of Xudabu-4 – also written in English as Xudabao and Xudapu – began in May 2022.

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

There are four steam generators in the set for a VVER-1200 PWR design. They act as heat exchangers where water carrying heat generated from the nuclear reaction is used to turn demineralised water into steam.

International Atomic Energy Agency data shows four units are currently under construction at the Xudabu site.

Xudabu-1 and -2 are of the CAP1000 PWR design, a domestic version of the Westinghouse AP1000 design.

Xudabu-3 and -4 are both of the Rosatom-supplied VVER-1200 PWR technology.
