Abstract

CONJUNTO DE COMBUSTIBLE PARA UN REACTOR NUCLEAR DE AGUA LIGERA. UN CONJUNTO DE COMBUSTIBLE PARA UN REACTOR NUCLEAR DE AGUA LIGERA QUE INCLUYE UNA PLURALIDAD DE BARRAS DE COMBUSTIBLE VERTICALES (1O, 42) QUE ESTAN COLOCADAS, EN RELACION ESPACIADA EN DIRECCION LATERAL, ENTRE UNA CHAPA INFERIOR DE UNION (11, 44) Y UNA CHAPA SUPERIOR DE UNION (12, 43). LA CHAPA INFERIOR DE UNION ESTA PROVISTA DE CANALES VERTICALES PASANTES (50) PARA CONDUCIR AGUA A TRAVES DE LA CHAPA INFERIOR DE UNION Y A LOS ESPACIOS SITUADOS ENTRE LAS BARRAS DE COMBUSTIBLE. TAMBIEN ESTA PROVISTA DE CANALES HORIZONTALES (51, 52) QUE CRUZAN LOS CANALES VERTICALES Y QUE ESTAN COLOCADOS PREFERIBLEMENTE, EN BORDES (54) EN LA CHAPA INFERIOR DE UNION, EN COMUNICACION ABIERTA CON LOS ESPACIOS SITUADOS ENTRE LAS BARRAS DE COMBUSTIBLE. EN AL MENOS ALGUNOS DE LOS CANALES HORIZONTALES INDICADOS, SE HAN DISPUESTO MUELLES HELICOIDALES (61, 62) CON EJE DE SIMETRIA HORIZONTAL DONDE LOS CANALES HORIZONTALES CRUZAN LOS CANALES VERTICALES.
