Enrichment plants

Treatment of the gaseous waste from enrichment plants removes fluoride and radioactive particles before discharge into the environment. The off-gas from centrifuges is typically filtered with NaF filters, alumina filters, and HEPA filters, and then discharged through a stack after radioactivity measurement.

In the enrichment plants, small amounts of liquid waste are generated from floor drainage and detergent wastes. These wastes are typically treated by flocculation using a flocculate agent such as polyaluminum chloride, and discharged into the environment.

Treatment of the solid waste is aimed at volume reduction for storage. Combustible wastes are incinerated, and then placed in 200 L storage drums. Incombustible wastes are placed directly in appropriate containers, and stored at the facilities.
