Terminal end-piece for a fuel assembly having a nose for orienting the flow of coolant fluid and corresponding assembly

A terminal end-piece for a fuel assembly of a pressurized water nuclear reactor, the assembly comprising fuel rods and a skeleton for supporting the fuel rods, the fuel rods extending in a longitudinal direction and being arranged at nodes of a substantially regular network, the support skeleton comprising two terminal end-pieces and guide tubes that connect the terminal end-pieces, the fuel rods being arranged longitudinally between the terminal end-pieces, comprising:

• noses for orientating flow of a coolant fluid of the reactor along adjacent longitudinal ends of the fuel rods, the noses being arranged at least one of in the nodes of the substantially regular network in order to be positioned in a longitudinal continuation of at least some of the fuel rods and at least some of the guide tubes of the support skeleton.
