Abstract

A device for transversely restraining the fuel rods of a bundle of fuel rods for a nuclear reactor assembly comprises an upper grid, a lower grid and an intermediate grid arranged in the direction of the axes of the fuel rods, each grid defining cells through which the fuel rods extend, the upper and lower grids being identical and made integral, and the intermediate grid being made of resilient material and arranged with its cells staggered transversely relative to those of the upper and lower grids so that the walls of the cells of the intermediate grid press the rods against the walls of the cells of the upper and lower grids.
