GEN IV Webinar Series 50: Overview of Waste Treatment Plant, Handford Site, February 25, 2021, 8:30 am (EST)


​Currently, the U.S. Department of Energy (DOE) stores ~90 million gallons of radioactive and hazardous waste in ~230 underground tanks at Hanford and Savannah River. At Hanford, approximately 20 million gallons of that waste is in a liquid form (supematant), approximately 10 million gallons is in the form of insoluble sludge materials and the remainder is in a partially soluble solid fform referred to as saltcake. Treatment and immobilization of the tank waste into a glass waste is planned with the Hanford Waste Treatment and Immobilization Plant (WTP) being the principal plant where this will be accomplished. This webinar focuses on the integrated flowsheet that encompasses storage, retrieval, pretreatment, immobilization, and disposal. The major emphasis or focal point will be the vitrification with respect to: 1) Troublesome waste componenets and their impact on glass formulation/operations; 2) Critical process and products performance properties (why and how they are measured); 3) Process control strategies and use/impact of glass models/algorithms; 4) Relationship between acceptable glass compositional regions and operation flexibility; 5) Significant advancements in glass formulation and the impact on the flowsheet/operations; 6) Operational lessons learned.
