FIELD: nuclear energy.
SUBSTANCE: invention relates to methods of removing residual heat emission of the reactor under the conditions of NPS blackout. Additional steam turbine plant 2 continues generating electric power for own needs using steam obtained in the steam generator due to the rector residual heat emission energy. Excess steam generated in the steam generator is directed to steam bypass 8, where it heats the cold water from cold water tank 6. Produced hot water is stored in hot water tank 9. Accumulated in hot water tank 9 hot water is directed to the steam generator. Waste in additional steam turbine plant 2 steam is directed to condenser 4, from where the condensate is drained into cold water tank 6. In the operating mode during the night-time electrical load dropout part of steam from the steam generator is directed to steam bypass 8, where it heats the cold water supplied from cold water tank 6. Produced hot water is stored in hot water tank 9. Drainage of the heating steam after steam bypass 8 is fed into the feed water circuit after high-pressure feed heater 12.
EFFECT: technical result is operation for electric power generation to the network in the normal mode of the plants safety increasing, absence of their idle time.
