The fourth and final steam generator for the Kursk Phase II Unit 1 reactor has been set in place, the installation carried out by the Kursk Branch of Energospetsmontazh JSC, Rosatom said on June 6.
“The installation of steam generators is an important stage in the creation of the reactor primary circuit system. It opens up a possibility to start the installation of the reactor vessel of the first power unit in the nearest future, and in the prospect – the installation of the main coolant pipeline,” said Oleg Shperle, ASE JSC Vice President, Director for Kursk NPP Construction Project.
The steam generator is a heat exchanger with a length of 15 meters and a weight of 355 tons. It is designed to produce steam supplied to a turbo generator to convert thermal power into electric power, Rosatom explained.
The Kursk plant on the banks of the Seym River in western Russia, supplies electricity for the Kursk Oblast and 19 other regions. The first of six RBMK-1000 units was undertaken in 1972 and connected to the grid in 1976. The final units of Kursk Phase I, (unit 5 and 6) were undertaken in 1985 and 1986, respectively, but construction was stopped in 1989 and canceled in 2012 for Unit 5 and cancelled in 1993 for Unit 6.
Construction of Kursk II, Unit 1, a VVER-1300/510 reactor, was begun in April 2018. Earth moving was begun in 2017 and involved excavation of 1.2 million cubic meters of earth. The first concrete pours for the unit got underway in November of that year.
