REACTOR PLANT EMERGENCY COOLING DEVICE Russian patent published in 2018 - IPC G21C15/18 

FIELD: nuclear engineering.

SUBSTANCE: invention relates to nuclear power plants with a reactor cooled by pressurized water and represents a reactor plant emergency cooling device, which contains a nuclear reactor connected with a steam generator by a circulation pipeline, connected by a steam line, with installed on it a fast-acting shut-off valve, with a turbine and a feed pipeline, on which stop valves and a non-return valve with a feed pump are installed. Steam generator is equipped with an emergency circuit consisting of a tank with water with a safety diaphragm at the inlet of the overflow line and a cooling circuit that is connected by a pipeline with installed on it auxiliary electric pump and the check valve. Steam generator is also connected to the located in the water tank bubbling device, with located on the steam pipeline a quick-acting reduction unit and to back-pressure steam turbine.

EFFECT: increasing the reliability of the reactor plant emergency cooling.
