Abstract

L'INVENTION CONCERNE UN SYSTEME DE DETECTION ET DE LOCALISATION D'ELEMENTS COMBUSTIBLES DEFECTUEUX DANS UN COEUR DE REACTEUR NUCLEAIRE. LEDIT SYSTEME COMPORTE COMME COMPOSANT PRINCIPAL UNE VALVE 42 DESTINEE A PRELEVER UN ECHANTILLON COMBINE DU FLUIDE REFRIGERANT QUI EST ASPIRE DANS UNE BRANCHE 40A EN PASSANT TOUT D'ABORD DANS UNE SECTION COLLECTRICE 51 PAR UNE UNITE DE POMPAGE 50 QUI LE REFOULE ENSUITE DANS UNE SECTION 48 DE DETECTION DES NEUTRONS. SI UNE EMISSION DE NEUTRONS EST DETECTEE, LA VALVE 42 PRELEVE ALORS DES ECHANTILLONS INDIVIDUELS QUI SONT ASPIRES DANS UNE SECONDE BRANCHE 40B PAR UNE UNITE DE POMPAGE 54 QUI LES REFOULE DANS UNE SECONDE SECTION 52 DE DETECTION DES NEUTRONS. L'ANALYSE INDIVIDUELLE DES ECHANTILLONS PERMET DE DETERMINER LA OU LES AIGUILLES DE COMBUSTIBLE DU OU DES ASSEMBLAGES RESPONSABLES DE L'EMISSION DES NEUTRONS. APPLICATION NOTAMMENT AUX REACTEURS SURREGENERATEURS RAPIDES REFROIDIS PAR UN METAL LIQUIDE.
