Abstract

Structure de grille pour assemblage combustible nucléaire, formée d'armatures à rainure, emboitées à l'endroit de leurs rainures, pour former des cellules destinées à recevoir des éléments combustibles, les armatures (15, 17) étant d'une épaisseur non uniforme et comportant des bandes d'une épaisseur sensiblement plus grande que les zones comprises entre ces bandes, les rainures étant formées dans les bandes plus épaisses (23, 33), les armatures étant réunies par soudage à l'endroit de ces bandes plus épaisses.
