Abstract

CONJUNTO COMBUSTIBLE PARA UN REACTOR NUCLEAR. CONJUNTO COMBUSTIBLE PARA UN REACTOR NUCLEAR, PREFERENTEMENTE DEL TIPO REACTOR DE AGUA A PRESION, CON UNA SERIE DE BARRAS COMBUSTIBLES (2) COLOCADAS AL LADO UNAS AL LADO DE LAS OTRAS MEDIANTE UNOS SEPARADORES (4, 5) COLOCADOS A LO LARGO DE LAS BARRAS COMBUSTIBLES ASI COMO UNOS TUBOS DE GUIA (3) COLOCADOS ENTRE LAS BARRAS COMBUSTIBLES (2) EN PARALELO A ELLAS, EXTENDIENDOSE DICHOS TUBOS DE GUIA (3) A TRAVES DE LOS SEPARADORES (4, 5) Y CON UNA TOBERA SUPERIOR (6) Y UNA TOBERA INFERIOR (7) ENTRE LAS QUE SE FIJAN LOS TUBOS DE GUIA (3). SEGUN LA INVENCION SE COLOCAN EN EL SEPARADOR (5) MAS CERCANO A LA TOBERA INFERIOR (7) UNOS MANGUITOS INFERIORES (8) PARA LOS TUBOS DE GUIA (3). LOS MANGUITOS INFERIORES (8) QUEDAN FIJADOS DE MANERA RIGIDA A DICHO SEPARADOR (5) Y DESCANSAN CONTRA LA TOBERA INFERIOR (7). LOS MANGUITOS INFERIORES (8) TIENE UN PRIMER ELEMENTO DE FIJACION PARA ENGANCHARSE MEDIANTE EL A UN SEGUNDO ELEMENTO DE FIJACION, COLOCADO AL FINAL DEUN TUBO DE GUIA, DE MODO QUE EL TUBO DE GUIA (3) QUEDA RIGIDAMENTE BLOQUEADO EN EL SENTIDO DE ROTACION.
