A roadmap for reuse of depleted uranium hexafluoride and its conversion products

Objective: Study the reuse of depleted uranium hexafluoride (DUF₆) and its conversion products. Methods: By studying the relevant research results of foreign countries and combining with the development of China, the prospects for the reuse of DUF₆, depleted uranium metal and oxides, and fluoride were analyzed. Results: Combined with the inventory of DUF₆ in China and the annual growth rate of 1500 ∼ 2000 tons, the road map for the reuse of DUF₆, depleted uranium metal and oxides, and fluoride were given in three stages: near-term, medium-term and long-term. Conclusion: In the near future, the safe storage of depleted UF₆ should be considered, and relevant research work on the reuse of depleted uranium and fluorine products should be strengthened, and carry out research in the field of high value-added utilization.
