摘要： PROBLEM TO BE SOLVED: To provide a metal cask for radioactive substance, which is manufactured at low costs by enabling a heat-transfer fin to be welded directly to a main body of a trunk.
SOLUTION: In the metal cask for spent fuel, the main body 11 of the trunk constituting a canister the stowing spent fuel, and an outer casing 17 placed by allowing spacing outside the main body 11 of the trunk, extend radially outward from the main body 11, and are joined by the heat-transfer fin 20A which radially extends outward from the main body 11 of the trunk and transfers heat to the outer casing 17. The heat-transfer fin 20A consists of a clad material made by combining two kinds of metal plates with each other to join them together. Moreover, one metal of the clad material is a metal material 21a of the same kind as used for the main body 11 of the trunk and the outer casing 17 and, at the same time, the other is composed of a good heat-transfer metal material 21b. The cask is so constituted that the main body 11 of the trunk is welded directly to the metal material of the same kind for the clad material mentioned above.
