Department of Nuclear Engineering, Idaho National Engineering Laboratory, Lockheed Martin Idaho Technologies, Idaho Falls, Idaho 83402 The effect of mixed modifiers on nuclear waste glass processing, leaching, and Raman spectra [Elektronische Daten] [S. V. Raman] Borosilicate glasses with different waste loadings were prepared by ambient melting, quenching, and annealing. Some melt compositions partially crystallize to durable phases of zircon and forsterite. The coexisting liquid quenches to glass and endures the leach tests. The waste loading dependent leach rate trends of these glasses are reminiscent of the mixed alkali effect. Raman spectra suggest initial increase in durability with increases in the depolymerization of silicate species. Fluorine and hydroxyl ions also contribute to depolymerization. Tetraborate and metaborate rings are identified in the Raman spectra. The durability is enhanced when tetraborate bands are more intense than the metaborate bands.
