A grid for supporting and spacing nuclear fuel rods, particularly at the nodes of a triangular array, has a peripheral frame of regular polygonal, typically hexagonal, shape and at least two beds of wires spaced in the longitudinal direction of the fuel assembly. Each bed has at least two series of mutually parallel wires secured to said frame at the end thereof, the wires of a same one of said series being parallel to two opposed side of said frame and all said wires defining passages for said fuel elements.
A spacing grid for a longitudinal nuclear fuel assembly having a bundle of parallel fuel elements arranged in a regular triangular array, said grid having a peripheral frame of regular hexagonal shape consisting of six side plates and at least two beds of wires spaced in a longitudinal direction, each of said beds having only two separate series of mutually parallel wires, said wires having ends secured to said frame, the wires of a same one of said series being parallel to two opposed sides of said frame, all said wires defining passages for supporting ...
