Abstract

Dispositif et procédé de réparation d’un assemblage de combustible nucléaire Le dispositif de réparation est prévu pour la réparation d’un assemblage de combustible nucléaire comprenant une structure de support (6) et des crayons de combustible nucléaire (4) agencés en un faisceau (5) présentant une ou plusieurs face(s) latérale(s) (24), la gaine (18) de l’un des crayons de combustible nucléaire (4) situés sur une dite face latérale étant endommagée et présentant une ouverture (28). Le dispositif de réparation possède une surface d’appui (36) et un dispositif de fixation configuré pour la fixation du dispositif de réparation sur la structure de support (6) et/ou sur un ou plusieurs parmi les crayons de combustible nucléaire (4) du faisceau (5) par l’intermédiaire du dispositif de fixation (38) de manière à appliquer la surface d’appui (36) contre la gaine endommagée en obstruant l’ouverture (28).
