Abstract

La présente invention relève du domaine des techniques nucléaires et concerne des ensembles de cartouches de combustible et plus précisément des éléments structurels d'une ossature rigide. L'ensemble de cartouches de combustible se compose d'une partie avant et d'une partie arrière qui sont reliées entre elles par des canaux de guidage disposés dans des cellules de grilles de séparation. Ces canaux de guidage sont solidement reliés au moins aux grilles de séparation d'extrémité. La hauteur (h) des grilles de séparation et l'épaisseur (δ) de la paroi des cellules des grilles de séparation sont choisies de telle sorte que leurs caractéristiques quantitatives satisfassent une condition déterminée de façon mathématique et expérimentale. Cette invention permet d'augmenter la rigidité de l'ensemble en cas de flexion transversale et longitudinale, d'accroître la rigidité angulaire dans des paires « canal de guidage - cellule de grille de séparation », et de réduire la flexion de l'ensemble de cartouches de combustible dans les passages situés entre les grilles de séparation ainsi que la libre flexion de l'ensemble de cartouches de combustible dans des champs thermiques et neutroniques non homogènes grâce à la tendance réduite de l'alliage A635 à gonfler sous irradiation.
