Unit 1 of Russia's Leningrad II nuclear power plant has been integrated into the heat supply system of the city of Sosnovy Bor, operator Rosenergoatom has announced.
The VVER-1200 reactor will replace electricity and heating capacity lost with the closure last December of the first of four RBMK-1000 units at the nearby Leningrad plant. All major manufacturing and production companies located on the industrial park in Sosnovy Bor were the first to receive the heat produced by Leningrad II-1, Rosenergoatom said.
The next stage will be to integrate the reactor's heat supply into the city's residential heating system. The net cost of heat generated at the Leningrad nuclear plant is far lower than that produced by boiler rooms run on organic fuel, the company said. In addition, the use of nuclear-generated heat avoids the emission of carbon dioxide and has a lesser impact on the environment.
