Abstract

CONJUNTO DE COMBUSTIBLE PARA EL REACTOR NUCLEAR DE UNA CALDERA PROVISTO DE AL MENOS UN GRUPO DE VARILLAS DE COMBUSTIBLE SIMILARMENTE ALARGADAS, RETENIDAS POR UNA GRAN CANTIDAD DE ESPACIADORES (8) Y DISPUESTAS EN UN CANAL DE COMBUSTIBLE. EL ESPACIADOR COMPRENDE UN GRAN NUMERO DE CELULAS RODEADAS POR UNA ESTRUCTURA EXTERIOR FORMADA POR UNA BANDA SITUADA EN EL EXTREMO. DE ACUERDO CON LA INVENCION, LA BANDA SE EXTIENDE POR EL LADO DE LA CORRIENTE SUPERIOR DEL ESPACIADOR MEDIANTE UNA FALDILLA (12), EN LA QUE SE PROPORCIONAN ABERTURAS (13). EN ALGUNAS DE ESTAS ABERTURAS SE DISPONEN ALETAS DE DEFLEXION (14) A FIN DE DESVIAR EL REFRIGERANTE, QUE FLOTA A LO LARGO DE LA PARED DEL CONJUNTO (6), EN DIRECCION HACIA EL CENTRO DEL ESPACIADOR RESPECTIVO.
