Abstract
PROCEDIMIENTO DE PREPARACION DE DIOXIDO DE URANIO A PARTIR DE HEXAFLUORURO DE URANIO. CONSISTENTE EN INYECTAR HEXAFLUORURO DE URANIO (13) Y VAPOR DE AGUA (14) EN EL REACTOR (10) DONDE SE REDUCEN LAS PARTICULAS DE FLUORURO DE URANIO EN LA ZONA DE LECHO FLUIDIFICADO (15) CON VAPOR DE AGUA E HIDROGENO INTRODUCIDOS POR LA CONDUCCION INFERIOR (16). LAS PARTICULAS FLUIDIFICADAS DEL LECHO SON DE DIOXIDO DE URANIO QUE PUEDE PROCEDER DE UNA TANDA ANTERIOR. LA ZONA SUPERIOR (17) DEL REACTOR (10) INCORPORA UNA SERIE DE FILTROS (18) PARA SEPARAR LAS PARTICULAS DE FLUORURO DE URANIO INFERIORES AL MM QUE SE RETIRAN POR UN CONDUCTO (19). EL OXIDO DE URANIO CON FLUORURO SE RECOGE EN UN DEPOSITO (21) Y S ETRANSPORTA (22) A UN HORNO ROTATORIO (23), RETIRANDOSE EL DIOXIDO DE URANIO (26).
