Abstract
L'invention concerne une grille cellulaire de positionnement de cartouches de combustible nucléaire. Ladite grille comporte des viroles définissant des ouvertures destinées à loger des barreaux de combustible nucléaire. Lesdites viroles sont groupées à l'intérieur d'une bande environnante et des éléments de positionnement des barreaux font saillie dans les ouvertures dont certaines au moins sont encadrées par des viroles tubulaires doubles comportant un élément de séparation formant une pièce de liaison qui sépare l'intérieur des viroles doubles en deux ouvertures analogues. Application aux assemblages combustibles pour réacteurs nucléaires.
