Intermediate wall separating a volume with hot liquid metal and a volume with cold liquid metal in a liquid metal cooled nuclear reactor

摘要

In a fast reactor constituted by an open-topped main vessel containing liquid metal coolant and an inner vessel mounted within the main vessel, a transverse skew wall forming an inner vessel extension is associated with a baffle which extends above the skew wall. A space formed between the baffle and the skew wall and containing a practically static volume constitutes a thermal shield between the hot liquid metal located within the inner vessel above the baffle and the cold liquid metal located between the inner vessel and the main vessel beneath the skew wall.
