Abstract

PURPOSE: To prevent leakage of tritium from a liquid metal cooled reactor by capturing the tritium formed in the reactor with a cold trap of a coolant purification system by use of isotope exchange reaction for hydrogen.
CONSTITUTION: Vessel 15 contg. NaH 14 is set through valves 16 to the upstream side of cold trap 13 of the primary Na purification system of a Na cooled fast breeder. Valve 18 is first closed, and valves 16 are opened to feed liquid Na 19 for cooling to vessel 15. NaH 14 in vessel 15 is dissolved in the Na, introduced into trap 13, and cooled to precipitate NaH. Valves 16 are then closed, and valve 18 is opened to actuate the breeder. Tritium formed in the breeder enters Na 19, and it is fed to trap 13 together with the Na. The NaH precipitated in trap 13 and the tritium bring about isotope exchange reaction, and the tritium is captured with trap 13, thus preventing leakage of tritium from the breeder.
