Russia shuts down the 925 MW Leningrad I-2 nuclear reactor

12 Nov 2020

Rosatom has shut down the second unit of the Leningrad I nuclear power plant in Sosnovy Bor, in western Russia. The 925 MW RBMK-1000 reactor will be replaced by a new power unit with a VVER-1200 reactor, which earlier in November 2020 received permission from the Russian Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor) to start pilot operation. The new reactor is scheduled to be connected to the network in the fourth quarter of 2020 and to be commissioned in early 2021.

The Leningrad I nuclear power plant in Russia consists of four RMBK-1000 nuclear reactors rated 925 MW (1,000 MW gross) each and commissioned between 1973 and 1981; the first unit was stopped in December 2018 and the second one has just been shut down and will be decommissioned. A second phase (Leningrad II) is adding four VVER-1200 reactors: the first one rated 1,085 MW was commissioned in October 2018, and the second one is expected in early 2021. Two additional units (3 and 4) rated 1,170 MW are under development.
