A process for the separation of gallium oxide from plutonium dioxide using a ''dry'' process has been developed. The process uses a reducing gas to generate a volatile gallium specie which is collected downstream. The effects of temperature, duration, flow rate, and sample size have been examined. Results indicate that temperature plays a strong role in the efficacy of gallium removal. Other variables have a much smaller effect on gallium removal efficiency. Gallium removal to approximately 1 ppm (atomic) has been observed. Gallium removal to sub-ppm levels appears feasible based on results-to-date
