Abstract

Dispositif de sécurité pour réacteur nucléaire, comprenant un élément absorbant comportant une tête de support réunie par une liaison déconnectable constituée par l'armature d'un électroaimant à l'extrémité d'une tige de manoeuvre verticale mobile axialement, cette liaison étant agencée de telle sorte qu'en cas de déconnexion, l'élément absorbant coulisse par gravité dans un passage délimité à travers le coeur du réacteur dans un boîtier ouvert. Le dispositif se caractérise en ce que la tige de liaison est associée à un organe métallique présentant un coefficient de dilatation notablement supérieur à celui de l'armature de l'électroaimant, cet organe métallique étant en appui par son extrémité sur la tête de l'élément absorbant ou sur la tige de manoeuvre. Application aux réacteurs nucléaires à neutrons rapides.
