The Defense Waste Processing Facility (DWPF) melter at the Savannah River site is well on its way in making this year`s goal of 150 radioactive glass canisters from high-level waste (HLW). However, the initial operation was marked by extreme difficulty in maintaining a stable pouring process. Flow fluctuations have been accompanied by an unusual flow phenomenon, termed wicking. In this situation, the falling glass stream wavered and departed from a normal vertical trajectory similar to the teapot effect. The pour spout and associated hardware connecting it to the canister have been coated and often plugged with glass. This resulted in extended downtime for frequent cleaning. Wicking occurred at both low and high flows, with a stable mid-flow ran. This paper describes the improvement in the pouring process.
