FLUIDIZED REACTOR REDUCTION OF UF6 TO UO2

摘要

Producing sinterable uranium dioxide by establishing a fluidized bed of uranyl fluoride solids, maintaining the bed of uranyl fluoride solids at temperatures in excess of 730.degree.C while countercurrently contacting the solids with excess steam to convert the uranyl fluoride to triuranium octoxide; and thereafter fluidizing the triuranium octoxide at temperatures below about 500.degree.C while countercurrently contacting the triuranium octoxide with excess hydrogen in the presence of steam whereby uranium dioxide is formed. The dioxide produced has a relatively low fluoride concentration.
