Effects of some glass additives on nuclear waste glass durability in water

One of the concerns with the use of borosilicate glass for immobilizing high level radioactive waste (HLW) is leach rate. A number of glass additives were studied in water. Solubilities of iron or germanium hydroxides influence the overall leaching behavior of HLW glass. PbO may form carbonates and...

Summary:One of the concerns with the use of borosilicate glass for immobilizing high level radioactive waste (HLW) is leach rate. A number of glass additives were studied in water. Solubilities of iron or germanium hydroxides influence the overall leaching behavior of HLW glass. PbO may form carbonates and effect an increase in Ca and Ba concentrations in the leachates. The rate of the glass used was higher than standard HLW glass but the mechanisms and conclusions are believed to be valid. 7 ref.--J.C.J.
