Abstract

SE SUMINISTRA UN CONJUNTO DE VARILLAS DE COMBUSTIBLE DE REACTOR NUCLEAR DE AGUA EN EBULLICION (10) CON UNA PLURALIDAD DE ESPACIADORES DE VARILLAS DE COMBUSTIBLE (12) QUE SE RECIBEN DESLIZANTEMENTE EN UN CANAL EXTERIOR (11). CADA UNO DE LOS ESPACIADORES DE VARILLAS (12) ESTA FORMADO POR, AL MENOS, UN RETICULO QUE DEFINE UNA PLURALIDAD DE CELDAS DE RETENCION DE VARILLAS DE COMBUSTIBLE (38). EL RETICULO ESTA FORMADO POR UNA PLURALIDAD DE PARES DE BANDAS ELASTICAS DE APOYO OPUESTAMENTE ORIENTADAS (20A-20F), TENIENDO CADA UNA DE LAS BANDAS DE APOYO UNA PLURALIDAD DE INDENTACIONES CARGADAS A RESORTE (34). EN UN ESTADO NO CARGADO, SE DESPLAZAN, ACERCANDOSE ENTRE SI, LAS INDENTACIONES OPUESTAMENTE ORIENTADAS (34) DE CADA PAR DE BANDAS, QUE DEFINEN CADA CELDA. EN UN ESTADO CARGADO, SE SEPARAN LAS INDENTACIONES OPUESTAMENTE ORIENTADAS (34) MEDIANTE LAS VARILLAS DE COMBUSTIBLE (13) PARA QUE SOSTENGAN Y RETENGAN LAS INDENTACIONES CARGADAS A RESORTE LAS VARILLAS DE COMBUSTIBLE (13).
