Abstract

EL SEPARADOR ES UN MIEMBRO DE LA CLASE DE SEPARADORES DONDE UNAS TIRAS SOLIDAS (62, 63) DE MATERIAL ESTAN SOLDADAS EN MIEMBROS DE TUBO SITUADOS EN INTERSICIOS (C) ENTRE LAS VARILLAS DE COMBUSTIBLE PARA FORMAR LA REJILLA SEPARADORA CONTINUA. LA MEJORA CONSISTE EN FORMAR REJILLAS DE SECCION REDUCIDA SUPERIOR E INFERIOR SEPARADAS DESDE JUEGOS PARALELOS SEPARADOS PARALELOS, PRIMERO (62) Y SEGUNDO (63) NORMALMENTE ALINEADOS, DE MIEMBROS DE REJILLA. UNA REJILLA (62, 63) SE FORMA PARA LA PARTE SUPERIOR DEL SEPARADOR, LA REJILLA REMANENTE SE FORMA PARA EL FONDO DEL SEPARADOR (NO SE ENSEÑA). SE UTILIZAN MIEMBROS DE TUBO (C) COLOCADOS EN INTERSICIOS ENTRE LA VARILLAS DE COMBUSTIBLE PARA INTERCONECTAR LAS REJILLAS. LOS MIEMBROS DE TUBO (C) TIENEN EN ELLOS UNA MUESCA, ESCALANADAMENTE; LAS MUESCAS (60, 61) ESTAN EN LA PARTE SUPERIOR DE LOS TUBOS PARA RECIBIR LA REJILLA SUPERIOR (62, 63) Y EN LA PARTE BAJA DE LOS MIEMBROS DE TUBO PARA RECIBIR LA REJILLA INFERIOR (NO SE VE). LAS REJILLAS ESTAN SITUADAS DENTRO DE LOS MIEMBROS DE TUBO CON RANURAS (C) Y ASEGURADOS, TIPICAMENTE MEDIANTE SOLDADO A LA PARTE SUPERIOR Y AL FONDO DE LOS TUBOS PARA FORMAR UNA ESTRUCTURA UNITARIA DE ESPACIADOR. DESPUES, EL MATERIAL DE EXCESO DE LA REJILLA (62, 63) QUE CRUZA EL INTERIOR DE LOS TUBOS (C) SE PERFORA FUERA DEL TUBO PARA ELIMINAR EL EXCESO DE MATERIAL ABSORVENTE DE NEUTRONES. EN EL SEPARADOR DESCUBIERTO, RESULTA ASI, DOS MIEMBROS DE REJILLA INTERNCONECTADOS QUE SE EXTIENDEN EN LA PARTE SUPERIOR Y EN EL FONDO DEL SEPARADOR TENIENDO MENOS MATERIAL QUE LA UNICA Y CONTINUA REJILLA DE LOS ANTERIORES. AL MISMO TIEMPO SE SIMPLIFICA EL MONTAJE DE LO QUE DE OTRA MANERA ES UN MIEMBRO DIFICIL DE CONSTRUIR. SE HACE UNA PROVISION PARA APLICAR EL SEPARADOR MEJORADO A SEPARADORES TENIENDO DIFERENTES INCLINACIONES ENTRE LAS VARILLAS DE COMBUSTIBLE SEPARADAS. TAMBIEN, SE DESCUBRE LA INCORPORACION DE LOS LLAMADOS ALETAS DE REMOLINO EN ALGUNOS SITIOS DE LAS REJILLAS (NO SE ENSEÑA) EN SUSTITUCION DE LOS MIEMBROS DE TUBO.
