Abstract

CONJUNTO DE COMBUSTIBLE PARA EL REACTOR NUCLEAR DE UNA CALDERA, CON AL MENOS UN CANAL ALARGADO, CONECTADO A UN REFRIGERANTE PREVISTO PARA QUE ATRAVIESE EL CANAL. SE DISPONEN EN EL CANAL UN GRUPO DE VARILLAS DE COMBUSTIBLE SIMILARMENTE ALARGADAS, RETENIDAS POR UNA GRAN CANTIDAD DE ESPACIADORES (8). EL ESPACIADOR TIENE UNA ESTRUCTURA EXTERNA PROVISTA ALREDEDOR DE UNA GRAN CANTIDAD DE VENTANAS (10). DE ACUERDO CON LA INVENCION, SE SITUAN ALETAS DEFLECTORAS (9) EN DICHAS VENTANAS Y SE DIRIJEN DE FORMA QUE DESVIEN EL AGUA DE REFRIGERACION QUE FLOTA A LO LARGO DE LAS PAREDES DEL CANAL DE COMBUSTIBLE EN DIRECCION HACIA EL CENTRO DEL CANAL PARA MEJORAR LA REFRIGERACION PARA LAS VARILLAS DE COMBUSTIBLE SITUADAS EN ESTA REGION.
