Abstract
A canister containing spent fuel assemblies is contained in a body of a transportation cask. A top opening of a vessel body of the canister is closed by a lid welded to the vessel body. A ring-shaped elastic tube is provided between the inner surface of the upper end portion of the body and the outer surface of the upper end portion of the vessel body. The tube seals the gap between these surfaces to prevent a fluid from getting into the gap between the surfaces through the top opening of the body. An inspection space for the insertion of a tester for detecting the welding state of the lid is defined between the inner surface of the upper end portion of the body and the outer surface of the upper end portion of the vessel body.
