Abstract

EN UN ENSAMBLAJE DE COMBUSTIBLE PARA UN REACTOR NUCLEAR, SE USAN ESPACIADORES PARA MANTENER JUNTAS Y FIJAS LAS VARILLAS (7) DE COMBUSTIBLE Y CONTROLAR LOS TUBOS (8) DE GUIA DE LAS VARILLAS, SI LOS HAY EN EL ENSAMBLAJE DE COMBUSTIBLE. PARA PERMITIR MEJORAR EL ENFRIAMIENTO DE LAS VARILLAS DE COMBUSTIBLE EN EL ENSAMBLAJE DE COMBUSTIBLE DURANTE LA OPERACION, SUBESPACIADORES (5,6) SE DISPONEN PARA CONTROLAR EL FLUJO DE AGUA ENFRIADA EN LA JUNTA DE COMBUSTIBLE. CON SUBESPACIADORES CONSTRUIDOS COMO SUBESPACIADORES INTERNOS (5) Y SUBESPACIADORES EXTERNOS (6), LOS CUALES ESTAN SITUADOS ALTERNATIVAMENTE A LO LARGO DEL ENSAMBLAJE (1) DE COMBUSTIBLE, ES POSIBLE CREAR UN FLUJO CRUZADO EL CUAL ACTUA ALTERNATIVAMENTE ENTRE LAS REGIONES INTERIOR Y EXTERIOR EN EL ENSAMBLAJE DE COMBUSTIBLE, EN DONDE EL AGUA ENFRIADA SE MEZCLA CON UN GOTEO ESENCIALMENTE MANTENIDO A BAJA PRESION. EL FLUJO CRUZADO TAMBIEN PROVEE DISTANCIAS CORTAS ENTRE LAS REGIONES DE TURBULENCIA, LAS CUALES APARECEN DESPUES DE CADA ESPACIADOR, EL CUAL ES ESPERADO PARA CONDUCIR A UN ALTO MARGEN DNB Y UN GOTEO DE BAJA PRESION.FIG 1B Y 1C.
