Abstract
UN SEPARADOR PARA USO CON UN MANOJO DE COMBUSTIBLE EN UN REACTOR NUCLEAR INCLUYE UNA MATRIZ DE CASQUILLOS (F'') PARA RODEAR LAS VARILLAS DE COMBUSTIBLE INDIVIDUALES (12'') EN UN MANOJO; UNA BANDA (40) QUE RODEA LA MATRIZ Y DEFINE UNA PARED PERIFERICA DEL SEPARADOR, LA BANDA TENIENDO UN EXTREMO SUPERIOR; Y UNA PLURALIDAD DE INDICADORES DE FLUJO SEPARADOS LATERALMENTE (44) QUE SE EXTIENDEN HACIA ARRIBA DESDE EL EXTREMO SUPERIOR, CADA INDICADOR DE FLUJO (44) TENIENDO UNA PARTE INFERIOR SUSTANCIALMENTE VERTICAL (46) Y UNA PARTE SUPERIOR INCLINADA (48) QUE SE EXTIENDE DESDE LA PARTE VERTICAL. LA PARTE VERTICAL (46) Y LA PORCION INCLINADA (48) SE FORMAN CON PLIEGUES LOCALIZADOS CENTRALMENTE (50, 50'') QUE DEFINEN DOBLECES INVERSOS EN LAS PORCIONES SUPERIOR E INFERIOR DEL INDICADOR.
