Abstract

Les grilles d'espacement de combustible nucléaire (100) comportent un contact de crayon élastique à déviation limitée (461). Les grilles d'espacement (100) peuvent en plus comporter un contact rigide (462) sans fonctionnalité élastique. Un degré de déviation peut être choisi sur la base d'un seuil de déformation plastique, d'un mouvement maximal de crayon combustible (14), de charges transversales prévues en relation avec l'assemblage combustible, l'inspection, la manipulation, le transport, le fonctionnement, des accidents et/ou n'importe quelles autres caractéristiques de fonctionnement. Les grilles d'espacement (100) comportent des contacts élastiques à déviation limitée (461) et/ou des contacts rigides (462) dans plusieurs arrangements dans la grille d'espacement (100) et/ou sur un seul crayon combustible (14). Les grilles d'espacement (100) sont compatibles avec un procédé de fabrication simple qui forme des composants rigides, limitant la déviation, et des composants élastiques à partir d'un seul support. Les grilles d'espacement de combustible (100) sont utilisables avec plusieurs types d'assemblages combustibles.
