ABSTRACT:
A nuclear reactor fuel of the kind comprising multi-pins (10) located in a hexagonal wrapper (11) and stabilized by a series of spacing grids (12) has an internal grid support cage (13) formed by six vertical limbs (20) inside the wrapper. The limbs of the cage have upturned parts (14) which engage into the cellular structure of the grids such as lying between two adjacent unit cells (16). The cells have tabs (21 in FIG. 3 and 52 in FIG. 5) which can be welded to the upturned parts.
