Leningrad II unit reaches first criticality
Rosenergoatom, the electric power division of Rosatom, Russia’s state-owned nuclear power corporation, announced on August 31 that Leningrad II-2 has achieved initial criticality. The unit is one of two Generation III+ VVER-1200 pressurized water reactors at the Leningrad nuclear plant.
Leningrad II-2 is scheduled for commercial start early next year, replacing Leningrad I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor that will permanently cease operation at the end of 2020 after 45 years of service. Fuel loading at Leningrad II-2 began in July.
