There are a variety of spent fuels on reactor types, fuel types, burnup, and cooling periods, in Japan. On the direct disposal study, to set model inventories for design and performance assessment, we have to categorize many kinds of spent fuels considering with its characteristics and volumes. Spent fuels volume estimation has been performed based on model calculation, and then, it was discussed about characteristic grasp of fuels and view point of categorization to set model inventories.
