APPARATUS FOR SEALING NUCLEAR REACTOR CAVITY

摘要

PURPOSE: A nuclear reactor cavity sealing body is provided to examine robustness of a sealing body by performing a leak test before supplying water, thereby preventing reworking and massive leakage of radiation in beforehand. CONSTITUTION: A nuclear reactor cavity switching part(110) comprise a sliding guide(111) and a nuclear reactor cavity cover(112). The sliding guide guides a movement route of the nuclear reactor cavity cover. The nuclear reactor cavity switching part is placed by being separated from a reloading water tank and a nuclear reactor container flange(31) with a predetermined distance. The nuclear reactor cavity cover completely separates the reloading water tank from a nuclear reactor cavity(200) by closing a nuclear reactor cavity opening part(114). A supporting part(120) supports the nuclear reactor cavity opening part.
