The first steam generator in a set of four has been installed for the Kursk 2-1 nuclear plant under construction in western Russia, developer Atomstroyexport said.

In a pressurised water reactor, the steam generators act as heat exchangers where water carrying heat generated from the nuclear reaction is used to turn demineralised water into steam. They are among the heaviest and largest components on the nuclear island.

Atomstroyexport, a subsidiary of Russian state nuclear corporation Rosatom, said the Kursk 2-1 project schedule is for the installation of all four steam generators and the reactor pressure vessel before the end of 2022.

In March, the company said the last steam generator in the set was delivered to the Kursk 2-1 site. The 355-tonne components had been manufactured by an Atommash factory in Volgodonsk, southwest Russia.

The two new units under construction at the site of the existing Kursk nuclear power station will be the first of the VVER-TOI pressurised water reactor type. Construction of Kursk 2-1 began in April 2018 and of Kursk 2-2 in April 2019.

The VVER-TOI technology was developed from the 1,200 MW AES-2006 pressurised water reactor.
