Abstract
A nuclear reactor fuel element comprised of a plurality of fuel rods disposed in a plurality of spacers in which the tubular casing for each fuel rod is designed without regard to the mechanical stress produced by the spacers and has a reinforced wall thickness adjacent to the spacers which is thicker than the wall thickness of the tubular casing in other areas not adjacent to the spacers. The spacers are arranged in a circular mesh with a center support rod.
