Abstract

UN PAQUETE DE CONDUCTORES DE COMBUSTIBLE PARA UN REACTOR DE AGUA HIRVIENDO DE CIRCULACION NATURAL INCLUYE POR LO MENOS UN TUBO DE DERIVACION REFRIGERANTE 210 QUE ESTA POR LO MENOS PARCIALMENTE ABIERTO EN SU PARTE SUPERIOR 234 E INFERIOR Y SE EXTIENDE ALREDEDOR DE 2/3 DE LA ALTURA DEL PAQUETE DE CONDUCTORES. EL AGUA DENTRO DEL TUBO DE DERIVACION PERMANECE LIQUIDA. CUANDO SALE DE LA PARTE SUPERIOR DE LOS TUBOS DE DERIVACION 234, EMERGE Y ENFRIA EL FLUJO DEL EXTERIOR DEL TUBO. ESTE MONTAJE REDUCE LA PRESION DE GOTEO A TRAVES DEL NUCLEO, INCREMENTANDO EL FLUJO REFRIGERANTE. ADEMAS, EL REFRIGERANTE QUE EMERGE AYUDA A MEJORAR LA TRANSFERENCIA DE CALOR EN LOS NIVELES DE MAXIMO FLUJO DE CALOR 232 DENTRO DEL NUCLEO. UNOS AGUJEROS LATERALES 236 A TRAVES DEL TUBO DE DERIVACION 210 PUEDEN REALZAR AUN MAS LA DISTRIBUCION DE LA TRANSFERENCIA DE CALOR EN EL NUCLEO. LA REDUCCION DEL GOTEO DE PRESION EN EL NUCLEO Y LA DISTRIBUCION MAS UNIFORME DEL FLUJO DE CALOR PERMITE AL REACTOR FUNCIONAN EN UNOS NIVELESDE MAYOR POTENCIA.
