Abstract

L'INVENTION CONCERNE UN SOUS-ASSEMBLAGE COMBUSTIBLE POUR REACTEUR NUCLEAIRE REFROIDI PAR UN METAL LIQUIDE. LE SOUS-ASSEMBLAGE COMPORTE UN FAISCEAU D'AIGUILLES DE COMBUSTIBLE ENFERME DANS UNE GAINE CONTENANT UNE PREMIERE SERIE DE GRILLES EN NIDS D'ABEILLES POUR ESPACER LES AIGUILLES, LESDITES GRILLES PRESENTANT DES CELLULES SOUTENANT LATERALEMENT CHAQUE AIGUILLEDU FAISCEAU. UNE SECONDE SERIE DE GRILLES ALTERNANT AVEC LES PREMIERES PRESENTE DES CELLULES DESTINEES A SOUTENIR LATERALEMENT UNE AIGUILLE D'UN GROUPE PERIPHERIQUE, LES AIGUILLES DU GROUPE INTERNE DU FAISCEAU OCCUPANT UNE CELLULE CENTRALE COMMUNE DANS LAQUELLE ELLES NE SONT PAS SOUTENUES. APPLICATION AUX REACTEURS NUCLEAIRES SURREGENERATEURS A NEUTRONS RAPIDES REFROIDIS PAR UN METAL LIQUIDE.
