Abstract
L'invention concerne un sous-assemblage combustible, notamment pour surrégénérateur à neutrons rapides, et son procédé de dégainage. Chaque cellule des grilles de renforcement du sous-assemblage comporte des tampons élastiques de contact pour guider une aiguille de combustible, lesdits tampons formant un premier groupe qui, normalement soutient l'aiguille coaxialement dans sa cellule et un second groupe normalement à distance des aiguilles, mais qui constitue un second appui en cas de déplacement excessif des tampons du premier groupe. Chacune des aiguilles est retenue à une extrémité par une grille de maintien fixée à l'extrémité de la gaine. Application aux réacteurs surrégénérateurs rapides refroidis par un métal liquide.
