Reactor room at the Leningrad power station at Sosnovy Bor, St. Petersburg, Russia. Leningrad power station has four reactors, of the RBMK-1000 type, dating from 1973, 1975, 1979 and 1981 respectively. Their output is 1000 MW each. Nuclear fission power plants split a nucleus, normally of Uranium 235, producing two smaller nuclei whose combined mass is less than that of the original nucleus. The discrepancy is converted to large amounts of energy.
