AI Technical Summary
The uranium dioxide powder produced by the dry process has a low oxygen-uranium ratio, and hydrogen and water vapor enter the post-processing process, affecting product quality. It is difficult to achieve continuous collection and prevent water vapor from entering the powder collection container.
A uranium dioxide powder stabilization system was designed, including an isolation unit, a pretreatment air intake unit, and a stabilized air intake unit. The isolation unit was set up to prevent hydrogen and water vapor from entering the treatment unit. The pretreatment air intake unit was used to remove water vapor and hydrogen from the uranium dioxide powder. The stabilized air intake unit adjusted the oxygen-uranium ratio. Continuous treatment was achieved by connecting multiple stabilization systems in parallel.
The oxygen-to-uranium ratio of uranium dioxide powder is improved, the flexibility and safety of the production line are enhanced, continuous production is achieved, and the impact of hydrogen and water vapor on product quality is avoided.
