Abstract

REJILLA DE MEZCLADO DE CAUDAL DE REFRIGERANTE PARA FAVORECER EL MEZCLADO DEL CAUDAL DE REFRIGERANTE A TRAVES DE UN CONJUNTO DE COMBUSTIBLE DE REACTOR NUCLEAR A LO LARGO DE Y ENTRE CADA DOS VARILLAS DE COMBUSTIBLE SOPORTADAS POR REJILLAS TRANSVERSALES DE APOYO MONTADAS EN TUBOS DE GUIA DE VARILLA DE CONTROL DEL CONJUNTO DE COMBUSTIBLE, CARACTERIZADA POR EL HECHO DE QUE DICHA REJILLA DE MEZCLADO DE CAUDAL DE REFRIGERANTE (34) COMPRENDE UNA PLURALIDAD DE TIRAS INTERIORES INTERFOLIADAS (44) DISPUESTAS CON UNA CONFIGURACION SIMILAR A UN ENVASE DE HUEVOS A FIN DE DEFINIR UNA PLURALIDAD DE ABERTURAS CELULARES INTERIORES (46) PARA RECIBIR A TRAVES DE ELLAS LAS RESPECTIVAS VARILLAS DE COMBUSTIBLE; AL MENOS, UN ASPA DE MEZCLADO (52) PARA CADA UNA DE POR LO MENOS UN NUMERO DE LAS MENCIONADAS ABERTURAS CELULARES INTERIORES (46), ESTANDO DISPUESTA EL ASPA DE MEZCLADO EN UNA DE LAS TIRAS INTERIORES Y SOBRESALIENDO DE ELLAS EN EL SENTIDO DE CIRCULACION DEL CAUDAL DE REFRIGERANTE Y, GENERALMENTE, HACIA ELINTERIOR, HACIA EL EJE LONGITUDINAL DE LA ABERTURA CELULAR, DE UNA MANERA TAL QUE DESVIE EL REFRIGERANTE LATERALMENTE DESDE UNA VARILLA DE COMBUSTIBLE HACIA UNA VARILLA DE COMBUSTIBLE ADYACENTE; Y UN SALIENTE RIGIDO (54) ASOCIADO CON CADA ASPA DE MEZCLADO (52) ESTANDO DISPUESTO EL SALIENTE EN LA TIRA INTERIOR Y SOBRESALIENDO DESDE ELLA HACIA EL INTERIOR DE LA ABERTURA CELULAR INTERIOR ASOCIADA (46) DE MANERA QUE PROTEJA EL ASPA DE MEZCLADO ASCIADA (52) CONTRA IMPACTO PERJUDICIAL CUANDO UNA VARILLA DE COMBUSTIBLE DISPUESTA EN LA ABERTURA CELULAR SUFRE MOVIMIENTO LATERAL.
