FIELD: electricity.
SUBSTANCE: according to the proposed method of increasing manoeuvrability and safety of NPP on basis of thermal and chemical accumulation in the night hours of electrical load breakdown, a part of steam from SG through the device of steam distribution is directed to steam-and-water surface heat exchanger, where it gives heat to cold water pumped through cold water pump from HWC in CWC. The drainage of heating steam is supplied to the feed water tract of the main circuit after high-pressure heaters in front of the SG. Due to the electrolysis of water, there is accumulation of unclaimed electricity in the form of hydrogen and oxygen, which are supplied to the receivers by means of booster hydrogen and oxygen compressor units. In the event of an accident with complete de-energization of the NPP, the steam generated by the residual heat release of the reactor installation is directed via the steam distribution device to an additional STP that generates electricity for the power supply of NPP's own needs.
EFFECT: increased agility and security of double-circuit NPP on the basis of thermal and chemical base electricity storage in the form of hydrogen fuel and hot water.
