Abstract

UN COEUR D'ASSEMBLAGES COMBUSTIBLES D'UN REACTEUR NUCLEAIRE PRESENTANT UN MOTIF DE REPARTITION DES BARRES AYANT SUBI UNE ROTATION PAR RAPPORT AU MOTIF DE REPARTITION DE LA STRUCTURE DE SUPPORT DES BARRES. DES BARRES DE COMBUSTIBLE ALLONGEES 12 SONT ORIENTEES EN UN RESEAU TRIANGULAIRE ET SUPPORTEES LATERALEMENT PAR DES STRUCTURES DE GRILLE POSITIONNEES SUR LA LONGUEUR DES ASSEMBLAGES. LE CONTACT INITIAL ENTRE ASSEMBLAGES SE SITUE SUR LES RENFORTS ARRIERE 26 AUX COINS DU MOTIF DE SUPPORT. LES BARRES DE COMBUSTIBLE, PERIPHERIQUES, ENTRE ASSEMBLAGES ADJACENTS SONT IMBRIQUEES DE FACON A MAINTENIR UN PAS TRIANGULAIRE A TRAVERS UN INTERVALLE DE JEU 36 ENTRE LES AUTRES PARTIES DES ASSEMBLAGES ADJACENTS. LE MOTIF DE BARRES EST DECALE ANGULAIREMENT PAR RAPPORT AU MOTIF DES SUPPORTS ARRIERE D'UN ANGLE DE SINUS EGAL A 2PC, OU P EST LE PAS DES BARRES INTERIEURES A L'ASSEMBLAGE ET C EST L'ESPACEMENT DE CENTRE A CENTRE ENTRE ASSEMBLAGES ADJACENTS.
