This Final Report describes the initial DuraMelter 100 (DM100) scale testing performed to support the development of next generation advanced joule-heated melters (NG AJHMs). The initial phase of testing investigated the impacts of plenum heaters and the partial drying of melter feed prior to its introduction into the melter. The tests demonstrate the overall impacts and benefits on processing characteristics such as increases in waste processing and glass production rates, and component volatility. The results also provide melting rates for sizing calculations and compatibility of feed and off-gas treatment systems. The tests were performed with a Hanford high level waste (HLW) composition previously processed on both the DM100 melter and the HLW Pilot Melter (DM1200). The simulated waste containing a high concentration of aluminum was originally specified by the Office of River Protection (ORP) for testing at VSL. This waste composition is representative of high-aluminum feeds that will be processed at the Hanford Tank Waste Treatment and Immobilization Plant (WTP) and that are expected to challenge waste loading and processing rate objectives. This works builds upon previous work performed at the Vitreous State Laboratory (VSL) of the Catholic University of America (CUA) for ORP to increase waste loadings and waste processing rates for high aluminum HLW waste streams by glass formulation optimization, bubbling, and modest increases in melt temperature. The present tests were conducted in response to the Task Plan WP-4.1.4.
