Abstract

L'INVENTION CONCERNE UN DISPOSITIF BIMETALLIQUE D'ENTRETOISEMENT DESTINE A UN ASSEMBLAGE COMBUSTIBLE DEVANT ETRE MONTE DANS LE COEUR D'UN REACTEUR NUCLEAIRE. CE DISPOSITIF D'ENTRETOISEMENT COMPREND UN ELEMENT EN "ZIRCALLOY" AUQUEL SONT FIXES PLUSIEURS RUBANS D'ACIER INOXYDABLE DISPOSES A LA SURFACE EXTERIEURE DE L'ELEMENT, DE MANIERE QUE L'AXE PRINCIPAL DES RUBANS SOIT ORIENTE A PEU PRES PERPENDICULAIREMENT A L'AXE PRINCIPAL DE CET ELEMENT. DANS UNE AUTRE FORME DE REALISATION, L'AXE PRINCIPAL DES RUBANS PEUT ETRE ORIENTE PARALLELEMENT A CELUI DE L'ELEMENT EN "ZIRCALLOY". DOMAINE D'APPLICATION : REACTEURS NUCLEAIRES.
