ABSTRACT:
The object of the invention is a nuclear reactor fuel assembly including fuel elements arranged in a supporting frame comprising two endpieces, the upper (1) and the lower (2) respectively, to which are attached the ends of a plurality of vertical tubes (3), each endpiece 1(2) including a plane base 11(21) in which are arranged two series of orifices 7 for retaining the tubes (3) and for the flow of the cooling fluid.
In accordance with the invention the base (11,21) of each endpiece (1,2) is joined side by side with an inner plate (15,25) equipped with the same series of orifices (70) for retaining the tubes (3) and for the flow of the fluid, and the orifices (70) have an oblong cross-section and are equipped with parts for attachment which cooperate with corresponding parts (31) for attachment of the said tubes (3) by transverse displacement of the inner plate.
