Abstract

ESPACIADOR PARA CONJUNTO DE COMBUSTIBLE DE REACTOR NUCLEAR COMPRENDIENDO EL ESPACIADOR UN ENREJADO EN FORMA DE CELDA PARA RETENER ELEMENTOS ALARGADOS PARALELOS COMO VARILLAS DE COMBUSTIBLE (4) EN UN HAZ CON SECCION TRANSVERSAL BASICAMENTE RECTANGULAR. LAS CELDAS ESTAN FORMADAS DE MANGUITOS BASICAMENTE REDONDOS TUBULARES (1), OFRECIENDO CADA UNO DE ELLOS UN PASO PARA UNOS DE DICHOS ELEMENTOS PAR FIJAR MUTUAMENTE DICHOS ELEMENTOS. DE ACUERDO CON EL INVENTO CADA ESPACIADOR CONSISTE EN DOS SUBESPACIADORES (5,6) COLOCADOS SEPARADOS ENTRE SI EN LA DIRECCION LONGITUDINAL DEL HAZ. UNO DE DICHOS SUBESPACIADORES (5) EN UN PAR FIJA ELEMENTOS QUE DESCANSAN BASICAMENTE EN UN LADO DE UN DIAGONAL DE LA SECCION TRANSVERSAL DEL HAZ, Y LOS OTROS SUBESPACIADORES (6) EN EL PAR FIJAN LOS OTROS ELEMENTOS DE MANERA QUE LOS ELEMENTOS QUE PASAN POR LOS MANGUITOS DEL PRIMER SUBESPACIADOR (5) PASAN, POSIBLEMENTE CON ALGUNA EXCEPCION, AL LADO DE LOS MANGUITOS EN DICHO SEGUNDO SUBESPACIADOR (6) Y VICEVERSA. ALGUNOS ELEMENTOS PUEDEN PASAR A TRAVES DE MANGUITOS EN AMBOS SUBESPACIADORES PARA FIJARLOS EN RELACION ENTRE SI.
