Nuclear fuel assembly
Patent
·
OSTI ID:6477291
The fuel assembly comprises a bundle of fuel pins spaced in parallel relation in a uniform lattice by means of support grids resiliently applied against the fuel pins and a rigid independent structure formed by two parallel end plates. Tie-rods extending between the end plates are disposed at uniform intervals at the lattice nodes. The bundle of fuel pins is supported by the first grid on a series of tubular spacer members which surround the lower ends of at least a number of tie-rods with provision for a clearance space. The tubular spacer members extend between the bottom end plate and the first grid, the tie-rods being permitted to pass freely through each grid by means of guide sleeves.
