Abstract

SE PRESENTA UN SISTEMA DE SUJECCION DE LA BOQUILLA DEL FONDO A UN MANGUITO GUIA DE UNA ARMADURA DE COMBUSTIBLE DE UN REACTOR NUCLEAR Y UN METODO QUE PERMITE RETIRAR LA BOQUILLA DEL FONDO Y SU REEMPLAZAMIENTO SIN DAR LA VUELTA A LA ESTRUCTURA DEL COMBUSTIBLE. EN SU FABRICACION, UN PERNO (24) DE DOS CABEZAS INSERTABLE EN EL FONDO ASEGURA LA PLANCHA ADAPTADORA DE LA BOQUILLA DEL FONDO (22A) PARA GUIAR EL TACO DEL EXTREMO DEL FONDO (28) DEL MANGUITO DE GUIA (14). EL PERNO DE DOS CABEZAS (24) NO SE PUEDE ROSCAR EN EL MANGUITO GUIA (14) DESDE LA PARTE SUPERIOR DE LA ESTRUCTURA DE COMBUSTIBLE DERECHA. EN LA RECONSTITUCION, UN CERROJO DE PERNO INSERTABLE DESDE LA PARTE SUPERIOR ASEGURA LA PLANCHA DEL ADAPTADOR DE LA BOQILLA DE FONDO ORIGINAL O DE REEMPLAZAMIENTO AL TACO DEL EXTREMO DEL FONDO DEL MANGUITO GUIA. EL CERROJO DEL PERNO SE INSERTA EN EL MANGUITO GUIA DESDE LA PARTE SUPERIOR DE LA ESTRUCTURA DEL COMBUSTIBLE. EL CERROJO DE PERNO NO SE PUEDE ROSCAR EN EL MANGUITO GUIA DESDE LA PARTE SUPERIOR DE LA ESTRUCTURA DE COMBUSTIBLE DERECHA PARA UNA SEGUNDA RECONSTITUCION. MENOS PREFERIBLEMENTE, EL CERROJO DE PERNO TAMBIEN PUEDE USARSE PARA LA MANUFACTURA ORIGINAL (EN LUGAR DE LOS PERNOS DE DOS CABEZAS (24) PREVIABLEMENTE DESCRITOS).
