ABSTRACT:
A fuel assembly for a nuclear fast neutron reactor comprises a shroud having an upstream head piece and a downstream tail piece. The shroud houses fuel elements having portions filled with fissionable and raw materials and plenums serving as accumulation reservoirs for fission gases evolved in the fuel. The fission-gas plenums are divided into a central and peripheral groups. At least one of these groups is positioned in the tail piece of the fuel assembly shroud downstream of the coolant inlet ports before the portions filled with fissionable and raw materials.
