Abstract
SE PRODUCEN BOLITAS DE COMBUSTIBLE NUCLEAR DE DIOXIDO DE URANIO UTILIZANDO UN POLVO DE DIOXIDO DE URANIO DE TIPO CERAMICO DERIVADO DE LA REACCION DE HEXAFLUORURO DE URANIO CON VAPOR DE HIDROGENO. EL POLVO SE TRANSFORMA EN BOLITAS Y LAS BOLITAS CRUDAS SE PASAN A TRAVES DE UN HORNO Y SOMETEN A COCCION RAPIDA, NORMALMENTE A TEMPERATURAS DEL ORDEN DE 2000-2200 (GRADOS) C Y DURANTE UN INTERVALO DE TIEMPO ENTRE 50 Y 500 SEGUNDOS. SE HA ENCONTRADO QUE LA SINTERIZACION A FUEGO RAPIDO DE TALES POLVOS EN ESTAS CONDICIONES PERMITE QUE SE CONSIGAN DENSIDADES DEL ORDEN DE 95 % DE LA DENSIDAD TEORICA CON CAMBIOS DE DENSIDAD DEL ORDEN DE 2 % E INFERIORES, SIN QUE SE REQUIERA COMPRESION MECANICA DE LAS BOLITAS CALIENTES. LA INCLUSION DE CRISTALES DE DIOXIDO DE URANIO DE SIEMBRA EN EL POLVO PELETIZADO AUMENTA EL TAMAÑO DE GRANO DE LAS BOLITAS DE COMBUSTIBLE.
