Abstract

Grille d'espacement pour ensemble de barres combustibles de réacteur nucléaire. Elle se compose d'un treillis de plaques formant des cellules multiples dans lesquelles pénètrent les éléments combustibles, et munies de saillies élastiques et de saillies rigides qui s'avancent dans les cellules et pressent contre l'élément combustible pour le maintenir. Des paires de plaques de grille s'intersectant, espacées longitudinalement, coopèrent avec d'autres plaques pour constituer un treillis à l'intérieur duquel chaque cellule contient des panneaux adjacents munis de saillies élastiques disposées à l'opposé de panneaux adjacents munis de saillies rigides. La frette périphérique limitant le treillis n'a que des saillies rigides. Applicable aux réacteurs nucléaires en généraL
