摘要： PROBLEM TO BE SOLVED: To provide a nuclear power plant emergency cooling system capable of efficiently removing decay heat generated by nuclear fuel material within a reactor core even when the power supply from external power source and emergency diesel generator is shut down.SOLUTION: When an isolation valve 20 is opened due to an accident of coolant loss, the vapor within a reactor pressure vessel (RPV) 2 flows through a steam exhaust pipe 19 and is condensed in a suppression pool 8 within a pressure suppression chamber 7. The vapor drives to rotate a steam turbine 13 arranged at the steam exhaust pipe 19 and connected to a compressor 12. A cooling medium, after being pressurized by the compressor 12, circulates within a closed loop including a cooling medium discharge pipe 17, a condenser 14, a cooling medium supply pipe 18 and an evaporator 11. The cooling medium is heated by the cooling water within the RPV 2 to be evaporated within the evaporator 11, and then liquefied by being cooled by the condenser 14. When the cooling medium is evaporated, the heat is deprived from the cooling water within the RPV 2. The temperature of the cooling water is reduced and thus the decay heat is removed from the nuclear fuel material.
