Method of processing radioactive sodium

Creators

Description

Object: To semi-continuously process through an on-line system in a safe and rapid manner great quantity of radioactive sodium discharged from a fast breeder reactor. Structure: Radioactive sodium is poured into a heating dish within a reduced pressure sealed container and steam is blown onto the radioactive sodium while controlling the reaction speed. The resultant sodium hydroxide waste liquid is thermally condensed. The reaction speed control is effected through control of the sodium temperature by the heater of the reaction dish and through control of the processing tank inner pressure. (Kamimura, M.)
