Abstract
A spent fuel storage rack that accommodates and stores spent fuels in a large number of cells formed in a grid pattern includes a flat rectangular plate-shaped base forming the bottom of the rack, columnar members extending upward from the four corners of the base, and at least a pair of upper and lower grid-shaped frame plates disposed above the base and fixed to and supported by the columnar members. Each of the cells is formed by assembling metal plates to which boron is added to a density greater than 1% into a polygonal tube, and the cells are arranged contiguously at fixed intervals in the grid-shaped frame plates.
