The basket of transport and storage cask must have not only a structural strength during transport and storage conditions, but also heat removal function. The basket material is also preferable to be light in order to reduce the weight of cask because it is very important to increase the number of fuel assemblies loaded in the cask for efficient transport and storage. Especially, aluminum alloy is a suitable base material for the basket due to its low density and high thermal conductivity. 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 Japanese Society of Mechanical Engineers. Therefore, various mechanical properties such as tensile strength at elevated temperature with or without long term aging and creep properties, etc.. And the allowable stresses of A5083FH-O have been evaluated according to the “Rules on Transport / Storage Packagings for Spent Nuclear Fuel (JSME S FA1-2007)”.
