DISPOSAL CANISTER FOR PRESSURIZED WATER REACTOR SPENT NUCLEAR FUELS

摘要

The present invention is to cool the nuclear fuel (hereinafter referred to as spent fuel) after burning in a pressurized light-water reactor in an intermediate storage facility, etc., so that it can withstand the ambient pressure when disposed in an underground rock and penetrates from corrosion by the surrounding ground water. It is to provide a spent fuel disposal container in which a spent fuel is loaded in a container that can be prevented, so that it can be disposed of efficiently and safely. The technical configuration is a spent fuel that can be disposed of by disposing of a spent fuel assembly. In the disposal container, the disposal container can control penetration through corrosion during the lifetime of the inner container and the disposal container having sufficient capacity for spent fuel loading in terms of nuclear criticality and radiation shielding, and which can withstand external pressure sufficiently. Characterized in that it includes an outer container.;Pressurized water reactor, spent fuel disposal container, internal container, external container, nuclear criticality, corrosion protection
