Abstract

EN UN DEPOSITO DE COMBUSTIBLE DE UN REACTOR DE AGUA HIRVIENDO (B) SE SITUA UNA CONSTRUCCION EN REJILLA TRIDIMENSIONAL DE CAPTURA DE DESPERDICIO DENTRO DEL VOLUMEN DE FLUJO DEFINIDO POR EL ENSAMBLAJE INFERIOR DEL DISCO DE UNION (T) ENTRE LA BOCA DE ENTRADA Y UNA REJILLA DE APOYO DE VARILLA DE COMBUSTIBLE (G). SE UTILIZA UN DISCO PERFORADO QUE TIENE AGUJEROS REDONDOS COMO PEQUEÑO CONSISTENTE COMO PRECAUCION DE CERRADO INADVERTIDO DEBIDO A IMPUREZAS Y UN AGUJERO DE PASO CONSISTENTE CON REQUERIMIENTOS DE INTEGRIDAD MECANICA. EL DISCO PERFORADO SE COLOCA EN UNA CONSTRUCCION TRIDIMENSIONAL TAL COMO UNA BOVEDA (44), CILINDRO (60), PIRAMIDE, PIRAMIDE INVERTIDA (80) O UNA CONSTRUCCION ACANALADA (100) ATRAVESANDO EL VOLUMEN DE FLUJO DEL ENSAMBLAJE INFERIOR DEL DISCO DE UNION (T). COMO CONSECUENCIA DE ESTA CONSTRUCCION EN REJILLA TRIDIMENSIONAL, EL FLUJO TOTAL A TRAVES DEL AEREA DE LAS PERFORACIONES EN EL DISCO DE METAL NO SUPONE PERDIDA DE PRESION APRECIABLE EN EL ENSAMBLAJE INFERIOR DEL DISCO DE UNION (T) ENTRE LA BOCA DE ENTRADA Y LA REJILLA DE APOYO DE VARILLA(G). EL MOVIMIENTO DE FLUIDO EN LOS AGUJEROS RETENEDORES DE DESPERDICIO DE LA CONSTRUCCION DE REJILLA TIENE UNA BAJA VELOCIDAD DE FLUJO Y SUFRE UN CAMBIO DE DIRECCION ANTES DE PASAR A TRAVES DE LOS AGUJEROS PARA EVITAR QUE EL DESPERDICIO PASE A TRAVES DE LOS AGUJEROS DE LA REJILLA. FINALMENTE, ES POSIBLE INCORPORAR TRAMPAS PARA DESPERDICIO (72,95) DENTRO DEL VOLUMEN DE FLUJO DEL ENSAMBLAJE DEL DISCO INFERIOR DE UNION (T) QUE PUEDEN PROPICIAR LA CAPTURA Y POSTERIOR RETIRADA DE DESPERDICIO ATRAPADO TRAS EL RECAMBIO DEL DEPOSITO DE COMBUSTIBLE.
