摘要： PROBLEM TO BE SOLVED: To maintain sealing performance even if a cask is stored for a long time. SOLUTION: A metal gasket 2 is used to seal a space between a main body 501 of a trunk and a secondary lid 508. The gasket 2 has a structure where an inner skin 4 and an outer skin 5 are placed outside a coil spring 3 made of a shape memory alloy. Though the plastic deformation of the coil spring 3 occurs when the cask is sealed, the coil spring 3 recovers to an original condition due to the decay heat inside the cask and the bearing pressure on the gasket 2 is heightened to maintain sealing performance over a long time.

摘要： PROBLEM TO BE SOLVED: To provide an expeditious and effective method for sealing a cask against leakage. SOLUTION: A metal gasket 2 is located between a secondary lid 508 and a flange part 506 of a main body 501 of a trunk, and a leading-in hole 10 communicating with the outside of the lid 508 is formed in a gasket groove 9 where the metal gasket 2 is put. When the sealing is disrupted by the metal gasket 2 and in other cases, a rubber material is injected from the hole 10 and is vulcanized inside the lid 508 to form a new sealing boundary. Consequently, the sealing performance of the cask can be recovered temporary and effectively.

摘要： PROBLEM TO BE SOLVED: To simplify a transportation work of a cask. SOLUTION: A metal gasket 20 is used for tightness between a secondary lid 8 and a flange part 6 of a shell body, and when transporting a cask, the transportation is executed, using the metal gasket 20 as it is. Only a gasket groove 101 for the metal gasket 20 is machined and formed on the secondary lid 8. Since a replacing work with a rubber O-ring is not required by this cask 100, the transportation work of the cask 100 can be executed extremely simply.
