Abstract
CLAVIJA GUIA QUE ALINEA UNA TOBERA SUPERIOR DE UN CONJUNTO DE COMBUSTIBLE NUCLEAR CON UNA PLACA DE NUCLEO SUPERIOR DE REACTOR NUCLEAR, SUSTITUIDA TRABAJANDO EXCLUSIVAMENTE DESDE UNA POSICION SITUADA BAJO LA PLACA. LA CLAVIJA GUIA DE RECAMBIO TIENE UNA PORCION DE VASTAGO ACOPLADA CON LA PLACA Y TUERCA DE FIJACION QUE MANTIENE LA CLAVIJA GUIA ORIGINAL, MEDIANTE CONEXION A ROSCA Y/O CONECTOR EXPANSIBLE. UN SALIENTE FORMADO EN LA CLAVIJA SE APOYA CONTRA UNA SUPERFICIE INFERIOR DE LA PLACA Y UNA NARIZ DE LA CLAVIJA SE SITUA EN LA TOBERA SUPERIOR DEL CONJUNTO. UN CONECTOR EXPANSIBLE PREFERIDO TIENE UN CASQUILLO CON ESTRIAS EN SU SUPERFICIE EXTERNA Y SUPERFICIE CONICA INTERNA, INTRODUCIENDOSE EN EL EJE PERFORADO DE LA CLAVIJA GUIA ORIGINAL. UN OBTURADOR ROSCADO DE FORMA CONICA ES EMPUJADO AXIALMENTE POR ROTACION DEL VASTAGO DE LA CLAVIJA DE RECAMBIO PARA ENSANCHAR EL CASQUILLO. LAS ESTRIAS BLOQUEAN RIGIDAMENTE LA CLAVIJA DE RECAMBIO ENTRE EL SALIENTE Y TUERCA DE FIJACION. FIJANDO LA CLAVIJA DE RECAMBIO EN EL RESTO DE LA CLAVIJA ORIGINAL, LA INVENCION UTILIZA LOS MEDIOS DE FIJACION DE LA CLAVIJA ORIGINAL EN LA PLACA DE NUCLEO SUPERIOR.
