ABSTRACT:
Water-cooled nuclear reactor fuel assembly of the type comprising two end pieces, respectively an upper end piece and a lower end piece, said end pieces having openings for the circulation of the light cooling water, the spacing grids made from a single metal have a relaxation effect under irradiation and are constituted by two groups of perpendicular plates, said grids defining cavities, each of which is traversed either by a fuel rod, or by a connecting rod, said spacing grids being distributed along the connecting rods, the walls of each cavity having bearing members for holding in place the fuel rods, wherein the fuel rods are jointed to an end piece and wherein means are provided for maintaining the group of grids against one of the upper or lower end plates, both during the operation of the reactor and when it is shut down.
