Verification of Package's Containment System Using Metallic Gasket to Comply with Requirement for Both Transport and Storage

Mitsubishi Heavy Industries, Ltd. (MHI) has developed a transportable storage cask design; the \"MSF series\". The MSF series casks adopt metallic gaskets for both transportation and storage containment devices. In Japan, metallic gaskets are selected for storage cask as containment devices, but have never been used for transportation casks. In order to employ a metallic gasket for transportation, a new design has been adopted and the validity of the design has been confirmed.
