Nuclear fuel rod support grid with attachable spring and dimple support spacers
This paper describes a nuclear fuel rod support grid, it comprises a plurality of straps being interleaved with one another to form a matrix of hollow cells, each cell for receiving one fuel rod and being defined by intersecting pairs of opposing wall portions of the straps which wall portions are shared with adjacent cells; a plurality of fuel rod clamping springs and dimples being associated with the wall portions of the straps defining each cell and protruding into the cell so as to clamp a fuel rod therebetween; and a pair of spacers inserted in each cell along the strap walls portions defining each cell, one of the spacers supporting the springs and the other of the spacers supporting the dimples. The spacers being separate from and detachably mounted on the wall portions of the straps defining each cell.
