FIELD: nuclear plant equipment.
SUBSTANCE: invention relates to a device for the primary circuit of the circulation system of a double-circuit nuclear power plant, including a steam pressure compensator, electric heaters located in the lower part of the pressure compensator, standard control and safety valves, a thermally insulated pipe for supplying part of hot water to the upper part of the pressure compensator included in the system circuit circulation of the primary circuit of a double-circuit nuclear power plant. Hot water is supplied to the free volume of the HP through an annular pipe installed in the upper part of the HP, and holes are made in the annular pipe, half of which faces the inner surface of the HP body, and the other half down into the free volume of the HP.
EFFECT: increasing the reliability, safety and energy efficiency of the installation.
