Abstract

SE MUESTRA UN VARILLA DE COMBUSTIBLE DE DOS DIAMETROS (R) CON UN TUBO INFERIOR DE DIAMETRO GRANDE (24) PARA SUJETAR UNA COLUMNA DE PASTILLAS DE COMBUSTIBLE DE DIAMETRO GRANDE CORRESPONDIENTES (60) EN LA PARTE INFERIOR DE LA VARILLA DE COMBUSTIBLE, UN TUBO SUPERIOR DE DIAMETRO MENOR (22) PARA SUJETAR PASTILLAS DE COMBUSTIBLE DE DIAMETRO MENOR CORRESPONDIENTES (51) EN LA PARTE SUPERIOR DE LA VARILLA DE COMBUSTIBLE, Y UN REDUCTOR (26) SITUADO ENTRE LA PARTE SUPERIOR (46) DEL TUBO DE COMBUSTIBLE INFERIOR DE GRAN DIAMETRO (24) Y LA PARTE INFERIOR (44) DEL TUBO DE COMBUSTIBLE SUPERIOR DE DIAMETRO MENOR (22). LA COLUMNA INFERIOR DE LAS PASTILLAS DE COMBUSTIBLE DE GRAN DIAMETRO (60) SE APOYA EN SU EXTREMO INFERIOR EN UN RESORTE (68) Y ESTA POLARIZADA EN SU EXTREMO SUPERIOR DIRECTAMENTE CONTRA EL REDUCTOR (26); LA COLUMNA SUPERIOR DE LAS PASTILLAS DE COMBUSTIBLE DE MENOR DIAMETRO (51) ESTA APOYADA EN SU EXTREMO SUPERIOR TAN CERCA COMO SEA POSIBLE A LAS PASTILLAS DE COMBUSTIBLE DE DIAMETRO MAYOR SUBYACENTES. AMBOS TUBOS (22,24) ESTAN CONVENCIONALMENTE OBTURADOS Y CONSTRUIDOS A SUS EXTREMOS DISTANTES DEL REDUCTOR DE CAMPANA (26). SE MUESTRAN VARIOS TIPOS DE SECCIONES DEL REDUCTOR. ESTAS SECCIONES DEL REDUCTOR INCLUYEN UN REDUCTOR DE CAMPANA DE CONSTRUCCION METALICA SOLIDA, UN TUBO ENCAMISADO DE SECCION DECRECIENTE, Y FINALMENTE TUBOS ENCAMISADOS TELESCOPIZANTES SOLDADOS JUNTOS. SE LOGRA UN GRUPO DE COMBUSTIBLE QUE TIENE UNA DISTRIBUCION UNIFORME DE COMBUSTIBLE Y FLUIDO REFRIGERANTE CON RESPUESTA DE POTENCIA CRITICA UNIFORME RESULTANTE, NINGUNA REGION DE FLUIDO DE VAPOR NO UNIFORME, Y AREA DE FLUIDO MEJORADA EN LA REGION DE DOS FASES SUPERIOR DEL GRUPO.
