Abstract

SE MUESTRA UN ESPACIADOR INCONEL (W) PARA ADICION A UN ESPACIADOR DE REJILLA METALICA DE RESORTE UTILIZADO CON UN REACTOR NUCLEAR DE AGUA EN EBULLICION NUCLEAR CONVENCIONAL. EL ESPACIADOR METALICO DE RESORTE INCLUYE UNA MATRIZ DE VARILLA DE COMBUSTIBLE QUE CONTIENE CELDAS (C1)-(C4). CADA CELDA TIENE AL MENOS UNA PATA DE RESORTE Y AL MENOS DOS BRAZOS QUE RODEAN LAS VARILLAS DE COMBUSTIBLE. LA PATA DE RESORTE FUNCIONA PARA POLARIZAR UNA VARILLA DE COMBUSTIBLE CONTENIDA DENTRO DE LA CELDA (C) AL ESPACIADOR A UNA LADO DE LA CELDA. LOS DOS BRAZOS QUE RODEAN LAS VARILLAS DEFINEN PARADAS CONTRA LAS CUALES ESTAN POLARIZADAS LAS VARILLAS DE COMBUSTIBLE. LAS CELDAS ESTAN SOLDADAS A UNA MATRIZ UNITARIA Y PREFERENTEMENTE RODEADAS DE UNA BANDA METALICA. EL DEFLECTOR CICLONICO MEJORADO EN ESTE INVENTO INCLUYE UNA CINTA DE ACERO DE RESORTE EN FORMA DE "I". LA CINTA INCLUYE FIJACIONES SUPERIOR E INFERIOR PARA ENGRANAR LA ESTRUCTURA DE REJILLA SUPERIOR E INFERIOR RESPECTIVA DEL ESPACIADOR. LA CINTA EN FORMADE "I" SE RETUERCE PARA DAR UNA SUPERFICIE DE DEFLECTOR CICLONICO, SIENDO ESTE RETORCIMIENTO PREFERENTEMENTE Y LIGERAMENTE MENOR O MAYOR QUE EL TOTAL DEL RETORCIMIENTO NECESARIO. POR LO TANTO, LA BANDA SE INSERTA A LA REJILLA Y LA CONTORSION UTILIZADA PARA FIJAR LA BANDA EN SU LUGAR HASTA LA SOLDADURA SE HA UTILIZADO PARA SEGURA EL DEFLECTOR EN SU LUGAR. EN UNA INCORPORACION ALTERNATIVA SE FORMA UNA FILA DE DEFLECTORES CICLONICOS DE UNA LARGA CINTA DE MANERA QUE LOS DEFLECTORES CICLONICOS ESTEN UNIDOS EN UN EXTREMO. SE INSERTAN FILAS DE DEFLECTORES CICLONICOS EN EL ESPACIADOR COMO UNIDADES.
