Abstract

LA PRESENTE INVENTION CONCERNE UN DISPOSITIF DE FERMETURE DE L'ETUI DE TRANSPORT D'UN ASSEMBLAGE IRRADIE DANS UN REACTEUR NUCLEAIRE. CE DISPOSITIF SE CARACTERISE EN CE QU'IL COMPREND: UNE ETANCHEITE PRIMAIRE, COMPORTANT UN BOUCHON CIRCULAIRE IMMOBILISE EN ROTATION, ASSIS SUR UN SIEGE PRATIQUE DANS LA TETE D'ETUI, UN JOINT PLAT SITUE SUR LEDIT SIEGE ENTRE LA TETE D'ETUI ET LEDIT BOUCHON, UN VERROU MUNI D'UNE TETE DE PREHENSION; UNE ETANCHEITE SECONDAIRE SITUEE EN AVAL DE LADITE ETANCHEITE PRIMAIRE, ETANCHEITE SECONDAIRE CONSTITUEE PAR UN COUVERCLE DONT UNE PARTIE CYLINDRIQUE S'ENGAGE A L'INTERIEUR DE LA TETE D'ETUI. APPLICATION AUX ETUIS DE TRANSPORT D'ASSEMBLAGES IRRADIES DANS UN REACTEUR NUCLEAIRE.THE PRESENT INVENTION CONCERNS A CLOSING DEVICE FOR THE TRANSPORT CASE OF AN IRRADIATED ASSEMBLY IN A NUCLEAR REACTOR. THIS DEVICE IS CHARACTERIZED IN THAT IT INCLUDES: A PRIMARY SEAL, INCLUDING A CIRCULAR PLUG IMMOBILIZED IN ROTATION, SITTING ON A PRACTICAL SEAT IN THE CASE HEAD, A FLAT SEAL LOCATED ON THIS SEAT BETWEEN THE CASE HEAD AND LEDIT PLUG, A LOCK EQUIPPED WITH A GRIP HEAD; A SECONDARY SEALING LOCATED DOWNSTREAM OF THE said PRIMARY SEALING, SECONDARY SEALING CONSTITUTED BY A COVER OF WHICH A CYLINDRICAL PART IS ENGAGED INSIDE THE CASE HEAD. APPLICATION TO TRANSPORT CASES OF IRRADIATED ASSEMBLIES IN A NUCLEAR REACTOR.
