FIELD: power engineering.
SUBSTANCE: at complete blackout, steam generated at steam generator is directed to extra steam turbine plant owing to reactor core residual heat generation. Extra steam turbine plant generates required electric power for supply of the station auxiliaries during time required for recover of the station standard operating conditions. Extra steam turbine plant is connected to heat recovery boiler and to steam distribution device arranged upstream of high-pressure cylinder of the main turbine via pipeline. Steam hydrogen superheater is connected with system for production of hydrogen and oxygen. Equipment incorporated with steam gas plant is located outside the nuclear power station site.
EFFECT: higher efficiency and safety.
