L'installation comprend un alvéole (21) déplaçable verticalement dans une piscine et muni à sa partie haute d'une plaque de base équipée de moyens de serrage de la partie haute de l'assemblage. Un corps de centrage prévu pour être manipulable par un outil de manutention est destiné à coiffer l'embout supérieur de l'assemblage et à se verrouiller sur lui. Un outil (J) de manutention des crayons de combustible comporte une perche (142) munie de moyens permettant de l'amener au droit d'un alvéole (21) et contenant une pince à crayon déplaçable verticalement dans la perche. The installation is intended to repair assemblies comprising a skeleton formed of end pieces connected by tie rods removably attached to the upper end piece and grids distributed between the end pieces.
