COMBUSTIBLE GAS PROCESSING SYSTEM AND METHOD OF NUCLEAR REACTOR BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a combustible gas processing technology by which soundness of a nuclear reactor building is secured even when hydrogen leaks in accordance with a nuclear plant accident.SOLUTION: A combustible gas processing system 10 of a nuclear reactor building includes: a nuclear reactor building 14 which surrounds a nuclear reactor container 13 in which a nuclear reactor pressure vessel 12 for accommodating a reactor core 11 to which nuclear fuel is loaded is stored; and a gas processing part 20 which is provided in a communication hole 17 communicating with vertical hierarchies of a section 16 obtained by partitioning an internal space of the nuclear reactor building 14 by a partition body 15 to make combustible gas incombustible.
