About 50 million gallons of high-level mixed waste is currently stored in underground tanks at the United States Department of Energy’s (DOE’s) Hanford site in the State of Washington. The Hanford Tank Waste Treatment and Immobilization Plant (WTP) will provide DOE’s Office of River Protection (ORP) with a means of treating this waste by vitrification for subsequent disposal. Corrosion of the melter materials of construction by the low activity waste (LAW) glass can significantly affect the life of the WTP LAW melters. The materials that are in contact with molten LAW glass include Inconel 690 alloy and Monofrax™ K-3 refractory. This report presents the results from experiments that were conducted to evaluate the corrosion of Inconel 690 and Monofrax™ K-3 refractory in representative high waste loading LAW glass formulations under conditions where loss of volatile constituents was minimized.
