The basket of transport and storage cask must have structural strength, neutron absorption ability and heat dissipation function. Borated stainless steels are suitable for application to baskets in transport and storage casks for spent fuels. In order to use this material for cask basket, it is necessary to be registered to the "Rules on Transport/Storage Packagings for Spent Nuclear Fuel (JSME S FA1-2007)" by the Japan Society of Mechanical Engineers. Therefore, various mechanical properties of B-SUS304P-1 such as tensile strength at elevated temperature, fracture toughness and allowable stress have been evaluated according to the "Rules on Transport/Storage Packagings for Spent Nuclear Fuel (JSME S FA1-2007)".
