Characterization of Off Gas Flow Surges in the DWPF Melter
Conference
·
OSTI ID:4772
The Defense Waste Processing Facility (DWPF) is currently producing radioactive canisters containing vitrified high-level waste. A slurry of high-level waste and glass frit is fed into a joule-heated melter where the mixture is dried, calcined, and melted. The off gases produced are treated in an off gas system designed to remove radioactive particulate and volatile components before exhausting clean gases to the environment. Surges in the flow of off gas can occur by various means, and must be accommodated by the melter off gas system. A method for calculating the magnitude of off gas surges is presented and applied to actual plant data. The melter off gas control system is shown to mitigate the effects of most flow surges without significant impact to plant operations.
