NUCLEAR FUEL ASSEMBLY AND NUCLEAR REACTOR OPERATING PROCESS COMPRISING APPLICATION THEREOF

摘要

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.
