Abstract

Assemblage combustible de commande pour réacteurs nucléaires comportant une partie combustible dans une gaine et un élément modérateur mobile. L'invention concerne plus précisément le raccordement entre l'élément modérateur B et la tige de commande C. Le système de solidarisation consiste en une tête creuse solidaire de l'élément B comportant dans son couvercle une fente axiale et à l'intérieur de cette tête une bague munie de deux tétons qui peuvent former un système à baïonnettes avec des fentes ménagées dans un tube prolongateur de la gaine de l'assemblage combustible. La tige de commande C comporte à sa partie inférieure une extrémité apte à entraîner en rotation la bague et une pièce apte à traverser la fente du couvercle de la tête creuse. Application aux réacteurs nucléaires expérimentaux du type piscine.
