  • Fuel assembly having anti-corrosion grids
    Patent number: 4804516
    Abstract: Fuel assembly for the core of a nuclear reactor comprising spacing grids situated in the upper part of the assembly arranged at smaller intervals from one another than the grids situated in the lower part of the assembly. The upper grids ensure a more intense mixing of the coolant downstream than the lower grids, so as to reduce corrosion at the upper part and the temperature difference between the top of the sheath and the coolant.

  • Nuclear fuel assembly and nuclear reactor operating process comprising application thereof
    Patent number: 4649020
    Abstract: 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.
