摘要

PROBLEM TO BE SOLVED: To secure a cooling region for arranging cooling water between storage regions for inserting nuclear fuel. SOLUTION: A cell assembly 13 composed of a plurality of small cell assemblies 14 is included, and the small cell assembly 14 connects a pair of side plates 16A and 16B facing each other and a pair of side plates 16A and 16B facing each other. A storage having a plurality of partition plates 16C (16D, 16E) arranged in the above, and having a pair of side plates 16A, 16B and a plurality of partition plates 16C (16D, 16E) facing each other so that nuclear fuel can be inserted. A plurality of regions 15 are arranged side by side, and a first cooling region 17 through which cooling water can flow is formed between the storage regions 15, and the cell assembly 13 has side plates 16A and 16B in adjacent small cell assemblies 14. A plurality of small cell assemblies 14 are arranged side by side so as to face each other, and a second cooling region 18 through which cooling water can flow is formed between adjacent small cell assemblies 14.
