Transport of spent fuel after dry storage
It now appears that spent fuel may be stored in interim dry stores for longer than was expected. The safety analysis requires knowledge of the characteristics and behaviour of materials under these storage conditions. Despite much R&D, questions about material properties remain open. Two key issues are residual water after drying and subsequent radiolytic generation, and the possibility of cladding embrittlement caused by thermal transients during the cask drying process and its impact on the cooling of stored fuel.
