Process for converting UF6 into UO2

摘要

A process for converting UF6 gas into UO2 powder comprising blowing UF6 gas and steam into a fluid bed to produce UO2F2 particle, hydrating and dehydrating the UO2F2 particle to UO2F2 powder, and defluorinating and reducing the UO2F2 powder to UO2 powder. The UO2 powder is suitable for manufacturing a reactor fuel owing to its high activity, low remaining fluorine amount and excellent fluidity.
