FAST-BREEDER NUCLEAR POWER GENERATION SYSTEM

Japanese Patent JP2009250929

A

To provide a fast-breeder nuclear power generation system including a natural circulation type decay heat removal system device capable of surely preventing coagulation of sodium with excellent reliability.

The decay heat removal system device 28 includes a PRACS 25, an air cooler 26, and a decay heat removing system pipe 27 connecting the PRACS 25 to the air cooler 26. The pipe 27 includes a high-temperature pipe 27a for supplying high-temperature decay heat removing system coolant heated by the PRACS 25 to the air cooler 26 and a low-temperature pipe 27b for returning low-temperature decay heat removing system coolant cooled by the air cooler 26 to the PRACS 25. A heat pipe 31 including a condenser part 32, an evaporation part 33 and a heat insulation part 34 is set within the high-temperature pipe 27a with the condenser part 32 being turned to the air cooler 26.

JPS587198	[Title of the Invention] A core spraying device of a nuclear reactor
JPH0769454	INDUSTRIAL APPLICABILITY: Natural circulation type passive cooling system for a reactor plant containment structure.
