Abstract

In cellular grid structures for positioning an array of nuclear fuel rods by locating them individually in a ferrule joined to its neighbours to form the grid structure, the ferrules are formed in pairs from tubular members each deformed to provide a waist. A bridge piece 11 extends across the waist to divide the tubular member into two cells and it may incorporate a resilient member 14 which projects into the two cells to urge fuel rods in the cells towards co-planar dimples 13 formed in the tubular member opposite the resilient member. <IMAGE>
