Abstract

L'invention concerne une grille pour assemblage combustible de réacteur nucléaire comprenant une multiplicité de bandes disposées dans un cadre périphérique et imbriquées l'une avec l'autre pour supporter des barres de combustible. Selon l'invention, chacun des dispositifs à ressort 22, 26 consiste en une partie découpée d'une bande 12, 14 et ondulée pour être d'une forme généralement sinusoïdale formant au moins une protubérance centrale 38, 40 pour entrer en contact avec la surface d'une barre de combustible 18 adaptée pour s'étendre à travers une cellule 16 sur un côté d'une bande 12, 14 et au moins deux protubérances de support 34 aux extrémités opposées de la protubérance centrale 38 et s'étendant dans une cellule 76 de l'autre côté de cette bande 12, 14. Application aux centrales nucléaires.
