The nuclear fuel assembly comprises a bundle of fuel elements some of which contain a burnable neutronic poison, held in position at the nodes of a regular lattice by a skeleton having end pieces connected together by guide tubes occupying some of the nodes of the lattice. All the poison-containing elements are disposed so as to act on the reactivity of the adjacent assemblies in the heart of the reactor.

A nuclear fuel assembly comprising a bundle of fuel elements some of which contain burnable neutronic poison and a structure for retaining said fuel elements at the nodes of a regular lattice, said structure having end pieces connected together by guide tubes occupying some of the nodes of the lattice, wherein all of said poison-containing elements are so located as to affect the reactivity of adjacent fuel assemblies when located in the core of a reactor and wherein the poison-containing elements are disposed at the nodes of the lattice furthest away from said guide tubes.
