Abstract

Assemblage pour réacteur nucléaire, comportant un boîtier parallélépipedique ouvert et allongé, à axe vertical, contenant un faisceau d'aiguilles combustibles parallèles et à son extrémité supérieure un manchon prolongeant le boîtier, ce manchon présentant vers l'intérieur une epaisseur plus importante que celle du boîtier pour assurer la protection neutronique supérieure de l'assemblage. Selon l'invention, le manchon est relié à l'extrémité du boîtier par un dispositif de liaison déconnectable, permettant leur séparation. Application aux réacteurs à neutrons rapides.
