Abstract

UN HORNO ROTATORIO, PARTICULARMENTE PARA OBTENER DIOXIDO DE URANIO, A PARTIR DE HEXAFLUORURO DE URANIO, TIENE UNA DISPOSICION DE ENTRADA (1) Y UN TAMBOR GIRATORIO (14) CALENTADO. EL HEXAFLUORURO DE URANIO Y EL VAPOR REACCIONAN JUNTAMENTE EN LA DISPOSICION DE ENTRADA (1) PARA FORMAR FLUORURO DE URANILO, QUE ES ALIMENTADO AL INTERIOR DEL TAMBOR (14) CON LA AYUDA DE UN DISPOSITIVO (17) DE ALIMENTACION EN ESPIRAL ROTATORIO. EN EL TAMBOR, EL FLUORURO DE URANILO REACCIONA CON UNA CORRIENTE DE CONTRAFLUJO DE VAPOR E HIDROGENO, PARA PRODUCIR EL DIOXIDO DE URANIO. UN METAL POROSO O FILTRO DE CERAMICA (28) RODEA ESTRECHAMENTE EL DISPOSITIVO (17) DE ALIMENTACION EN ESPIRAL, PARA EXTRAER PARTICULAS DE LOS GASES PRODUCIDOS POR EL HORNO. EL FILTRO SE MANTIENE EN CONDICIONES DE LIMPIEZA MEDIANTE LA ACCION DE RASPADO DE UN NUMERO DE PALETAS HELICOIDALES QUE FORMAN PARTE DEL DISPOSITIVO (17) DE ALIMENTACION EN ESPIRAL. EL POLVO DEL DIOXIDO DE URANIO PRODUCIDO POR EL HORNO PUEDE PROCESARSE PARA OBTENER PELLETS (PASTILLAS) DE COMBUSTIBLE NUCLEAR.
