Abstract

SE DESCRIBE UNA PLACA DE ANCLAJE INFERIOR PERFECCIONADA Y UNA INTERFAZ DE CANAL PARA UN PAQUETE DE COMBUSTIBLE DE REACTOR CON AGUA EN EBULLICION. EL PAQUETE DE COMBUSTIBLE TIENE UNA PLACA DE ANCLAJE INFERIOR (L) PARA SUJETAR LAS BARRAS DE COMBUSTIBLE Y PERMITIR LA INTRODUCCION DE LIQUIDO DENTRO DEL PAQUETE DE COMBUSTIBLE. UNA PLACA DE ANCLAJE SUPERIOR MANTIENE LAS BARRAS DE COMBUSTIBLE SUJETAS POR LA PLACA DE ANCLAJE INFERIOR DE LADO A LADO Y TIENE UNAS ABERTURAS PARA DESCARGAR UNA MEZCLA DE AGUA Y VAPOR. UN CANAL CON SECCION EN FORMA DE POLIGONO (C), PREFERENTEMENTE CUADRADO, RODEA A LAS PLACAS DE ANCLAJE Y LAS BARRAS DE COMBUSTIBLE PARA CONFINAR EL FLUJO DE FLUIDO ENTRE LAS PLACAS DE ANCLAJE DENTRO DEL PAUETE. LA INTERFAZ DEL CANAL, AL RODEAR A LA PLACA DE ANCLAJE INFERIOR, SE RECONFIGURA PARA INCLUIR ELEMENTOS QUE INDUZCAN UNA RAPIDA CAIDA DE LA PRESION EN LA UNION INTERIOR DE LA PLACA DE ANCLAJE INFERIOR Y EL CANAL HACIA LA JUNTA EXTERIOR DE LA PLACA DE ANCLAJE INFERIOR Y EL CANAL.DEBIDO A ESTA RAPIDA CAIDA DE LA PRESION, LA PARTE INFERIOR DEL CANAL DE SECCION CUDRAD NO SE HALLA SOMETIDA A LA CARGA DE PRESION, Y LA PARTE INFERIOR REFUERZA A LA SUPERIOR. EN OTRO DISEÑO, SE REALIZA UN CIERRE DE LABERINTO EN LA REGION DE SOLAPAMIENTO, ENTRE EL CANAL Y LA PLACA DE ANCLAJE INFERIOR, CONFIGURANDOSE EN LA PLACA DE ANCLAJE INFERIOR O EL CANAL. EN UN SEGUNDO DISEÑO PREFERIDO, SE INCORPORA UN DIFUSOR (54) EN LA REGION DE SOLAPAMIENTO, ENTRE EL CANAL (C) Y LA PLACA DE ANCLAJE INFERIOR (L). EL DIFUSOR CREA LA DISTRIBUCION DE LA PRESION EN LA ZONA DE SOLAPAMIENTO LO CUAL LIMITA LA DESVIACION DEL CANAL.
