Effects of SiO{sub 2}, B{sub 2}O{sub 3}, Na{sub 2}O, Li{sub 2}O, Fe{sub 2}O{sub 3}, Al{sub 2}O{sub 3}, ZrO{sub 2}, Bi{sub 2}O{sub 3}, P{sub 2}O{sub 5}, and UO{sub 2} concentration on the properties of multicomponent borosilicate waste glasses were studied. The glasses are designed for vitrification of high-level radioactive waste (HLW). A one-component-at-a-time change approach was used. The baseline was a 50 wt% Hanford HLW blend glass designed to melt at 1350{degrees}C. The viscosity, electrical conductivity, and liquidus temperature of glasses were measured and first-order component coefficients were obtained.
