A dry conversion process to produce UO₂ powder is reported. Uranium fluoride (UF₆) is directly hydrolyzed with water vapor from a concentric nozzle to form uranyl fluoride (UO₂F₂), which is transferred to a rotary kiln by a screw and reduced to ceramic-grade uranium dioxide (UO₂) powder with backward mixing gases of vapor and hydrogen. Several of the main reactions and thermodynamics calculations for conversion of gaseous UF₆ to UO₂ powder are reported, including reactions for UO₂F₂+H₂O/H₂→UO₂/UO₃ and UO₂+HF→UF₄. The influence of the temperature of the first zone and the gas atmosphere of H₂O-H₂-HF on the fluorization of UO₂ by HF in term of thermodynamics are also discussed. Moreover, the influences of the dry conversion process parameters on the UO₂ physical properties are analyzed by qualification test results.
