  • Glass Formulations for Immobilizing Hanford Low-Activity Wastes: Summary of Preliminary Laboratory-Scale Testing (June 10, 2010), Report GSI-45, prepared for Office of Waste Processing (EM-31), U.S. Department of Energy
  • Laboratory-scale GSI-2000 glass immobilizes (i) a surrogate Hanford Tank 241-S-109 (high-Na2O) low-activity waste (LAW) composition, and (ii) a surrogate Hanford 222-S (high Na2O, high SO3) composite saltcake LAW waste composition, achieving 30 wt% and 27.7 wt% Na2O loadings, respectively (as compared to the then-current DOE benchmark of 20 wt%).
  • Glass Formulations for Immobilizing Savannah River Site High-Level Waste Sludge Batch 4 (SB4): Summary of Preliminary Laboratory-Scale Testing (June 28, 2010), Report GSI-46, prepared for Office of Waste Processing (EM-31), U.S. Department of Energy Laboratory-scale GSI-2000 glass immobilizes a surrogate Savannah River Site (SRS) SB4 high-level waste (HLW) composition, achieving 37 wt% waste loading (as compared to the then-current DOE benchmark of 34 wt%).
  • Glass Formulations for Immobilizing Hanford C-106/AY-102 High-Level Waste: Summary of Preliminary Testing (July 5, 2010), Report GSI-47, prepared for Office of Waste Processing (EM-31), U.S. Department of Energy GSI-2000 glass immobilizes a surrogate Hanford C-106/AY-102 HLW composition in a large-scale pilot test, achieving 34.8 wt% waste loading. Subsequently GSI achieved 39.3 wt% waste loading at laboratory-scale (as compared to the then-current DOE benchmark of 23 wt% ).
  • A New Approach to Glass Formulation Generates Improved Waste Loadings for Hanford HLW/LAW and Savannah River Site HLW (March 2011), Waste Management Conference, February 28 - March 3, 2011, Phoenix, AZ This publication summarizes the results of the previous three reports prepared for the U.S. Department of Energy’s Office of Waste Management.
