Abstract
A fast reactor fuel sub-assembly has honeycomb grids for laterally supporting the fuel pins. The grids are of two series and are arranged alternately along the bundle. The grids of a first series provide a discrete cell for each pin but the grids (7b) of the second series have a peripheral group of cells (14) only. The grids of the second series provide intermediate support of the edge pins to restrain bow. <IMAGE>
