A structural arrangement for a nuclear reactor fuel assembly. Top and bottom support plates, comprising fuel assembly outlet and inlet nozzles respectively, are separated by a plurality of metal tubes. Metal grids which serve to space and support fuel rods containing nuclear fuel are spaced along the length of the metal tubes. The metal grids are structurally attached to the metal tubes by sleeves, made of the same material as the metal tubes, which are spring loaded into the metal grid and spot welded to the metal tubes passing therein. |
