Development of an FBR Spent Fuel Cask for Post-Irradiation Examination

Japanese first prototype FBR \"MONJU\" is being constructed by Power Reactor and Nuclear Fuel Development Corporation (PNC). After a few cycles of it ' s 100 %power operation , several irradiated fuel assemblies will be transported to the PIE facility for the examinations to confirm their integrity and performance . The PIE facility will be constructed at PNC's 0-arai Engineering Center (OEC) and the fuel will be transported by sea. No existing cask can accomodate \"MONJU\" fuel since some are short in length and some are too heavy. So, it is necessary to develop a new cask which can transport fuel irradiated in \"MONJU\" to the PIE facility. This paper describes a work pertaining to the development of the PIE cask.
