燃料集合体におけるばね組立体の取付装置。A spring assembly m consisting of a vertical angle-shaped stopper 12 and a bifurcated hanging plate spring 11 is arranged at a required corner of a channel box b surrounding the fuel bundle, and the spring assembly m is attached to a bolt 13. In a device that is removably fixed to a corner post 5 of an upper tie plate, the intermediate shaft of the bolt 13 is composed of a lower male threaded portion 13c to be screwed into the corner post 5 and an intermediate shaft portion 13b having a slightly smaller diameter. The horizontal heads 11a and 12a of the leaf spring 11 and the stopper 12 are fitted into the portion 13b, and a center threaded hole 16a is provided on the lower side of the part 13b. Insert an annular or cylindrical retaining member 16 of the same size,
The center threaded hole 16a is inserted into the lower male threaded part 1 of the bolt 13.
A mounting device for a spring assembly in a nuclear fuel assembly, characterized in that the spring assembly is deformed so as not to be screwed into the spring assembly.
