Abstract

L'ASSEMBLAGE COMBUSTIBLE RECONSTITUABLE POUR UN REACTEUR NUCLEAIRE SELON LA PRESENTE INVENTION COMPORTE UN AGENCEMENT MECANIQUE POUR RELIER LES CHAUSSETTES DE BARRES DE COMMANDE AUX PLAQUES DES EMBOUTS SUPERIEUR ET INFERIEUR D'UN ASSEMBLAGE COMBUSTIBLE. DES MANCHONS 46, 60 RENFERMANT LES CHAUSSETTES 22 DE BARRES DE COMMANDE RELIENT ENTRE ELLES LES PLAQUES 32, 58 D'EMBOUTS SUPERIEUR ET INFERIEUR ET LES GRILLES SUPERIEURE ET INFERIEURE 14 D'ASSEMBLAGE COMBUSTIBLE. CHAQUE MANCHON 46, 60 EST FIXE A LA PLAQUE D'EMBOUT CORRESPONDANTE 32, 58 PAR DES RONDELLES DE RETENUE 48, 50, 82 DISPOSEES SUR LES COTES OPPOSES DES PLAQUES D'EMBOUT 32, 58. S'IL EST NECESSAIRE DE RETIRER DE L'ASSEMBLAGE UNE BARRE COMBUSTIBLE, ON PEUT ENLEVER LES RONDELLES DE RETENUE DE L'UN OU L'AUTRE DES EMBOUTS SUPERIEUR OU INFERIEUR DE MANIERE A DEGAGER L'EMBOUT DES CHAUSSETTES DE BARRES DE COMMANDE ET A EXPOSER AINSI, SOIT L'EXTREMITE SUPERIEURE, SOIT L'EXTREMITE INFERIEURE, DES BARRES COMBUSTIBLES A DES MECANISMES D'ENLEVEMENT DE BARRES COMBUSTIBLES.
