<p>PROBLEM TO BE SOLVED: To provide a nuclear fuel storage rack capable of preventing the rack body of a nuclear fuel storage rack from colliding against a side wall of other nuclear fuel storage rack or a storage pit adjacent to the nuclear fuel storage rack, even if it is to be slidable on the bottom surface of the storage pit, and a nuclear fuel storage rack group.SOLUTION: A nuclear fuel storage rack M that is aligned and stored in a storage pit 3 while housing nuclear fuel assemblies comprises: rectangular parallelepiped rack bodies 6 for housing the nuclear fuel assemblies; support leg parts 5 for supporting the rack bodies 6 so that they are slidable on the bottom surface 3b of the storage pit 3; and colliding members 15 disposed on both ends of sides 7 of the rack bodies 6 and protruding from the sides 7. The colliding members 15 include: a plurality of convex colliding parts 15A protruding from the sides 7; and concave support parts 15B that are placed between the colliding parts 15A adjacent to each other to connect the colliding parts 15A and that come into contact with the sides 7 to support the colliding parts 15A.</p> |
