摘要:
In a grid in a nuclear fuel assembly for supporting fuel rods, elongated straps intersect with each other to define grid cells. At least one pair of punched sections are formed, in spaced relation to each other, in each of peripheral walls of the respective grid cells. At least one of elongated spring elements is formed in the peripheral wall of each grid cell. Each spring element is formed such that a portion of the peripheral wall of the grid cell between the pair of punched sections bulges and projects into the grid cell. The spring element is capable of being deflected toward the peripheral wall of the grid cell. A pair of projections are formed in the peripheral wall of the grid cell respectively at both longitudinal ends of the spring element such that a pair of portions of the peripheral wall of the grid cell bulge. Both longitudinal ends of the spring element are connected respectively to the pair of projections.
