Abstract
A nuclear fuel assembly grid includes a multiplicity of spring structures for engaging fuel rods extending through the cells of the grid. Each spring structure is formed on each cell wall section to form a matrix of fuel rod receiving cells in the grid. Each spring structure is composed of a pair of spaced apart upper and lower opposite outer portions being integrally attached at their outer ends to the respective wall section, and a middle portion disposed between and integrally connected at its outer ends with respective inner ends of the upper and lower outer portions. The upper and lower outer portions extend in alignment with one another and in generally diagonal relation to the direction of the central longitudinal axis of the one cell between upper and lower portions of the wall section. The middle portion which contacts the fuel rod extends in generally transverse relation to the direction of the central longitudinal axis of the one cell.
