Abstract

L'invention concerne un assemblage destiné à être inséré dans un réacteur nucléaire, notamment dans un réacteur à neutrons rapides refroidi au sodium RNR-Na, comportant : - un corps creux d'assemblage (12), de forme allongée selon un axe longitudinal X, la paroi du corps creux comportant au moins une ouverture débouchante ; - un élément d'assemblage (14) inséré au moins en partie dans le corps creux (12), l'élément d'assemblage (14) comportant au moins une lame flexible (20) dont l'extrémité libre est conformée en crochet d'encliquetage (21) coopérant par encliquetage avec l'ouverture débouchante depuis l'intérieur du corps creux, de sorte à lier l'élément d'assemblage au corps creux; - au moins un moyen amovible de verrouillage de la lame flexible (20) encliquetée dans l'ouverture débouchante (122), le moyen amovible de verrouillage permettant d'empêcher la flexion de la lame flexible et ainsi de verrouiller la liaison entre l'élément d'assemblage et le corps creux.
