Title: Evaluation of environmental-control technologies for commercial nuclear fuel-conversion (UF/sub 6/) facilities

Technical Report ·
DOI:https://doi.org/10.2172/6671198· OSTI ID:6671198

At present in the United States, there are two commercial conversion facilities. These facilities process uranium concentrate into UF/sub 6/ for shipment to the enrichment facilities. One conversion facility uses a dry hydrofluor process, whereas the other facility uses a process known as the wet solvent extraction-fluorination process. Because of the different processes used in the two plants, waste characteristics, quantities, and treatment practices differ at each facility. Wastes and effluent streams contain impurities found in the concentrate (such as uranium daughters, vanadium, molybdenum, selenium, arsenic, and ammonia) and process chemicals used in the circuit (including fluorine, nitrogen, and hydrogen), as well as small quantities of uranium. Studies of suitable disposal options for the solid wastes and sludges generated at the facilities and the long-term effects of emissions to the ambient environment are needed. 30 figures, 34 tables.
