Improved Glass Compositions for Immobilization of SRP Waste
Radioactive waste produced from reprocessing nuclear materials for defense programs at Savannah River Plant (SRP) is stored in large underground tanks on the plant site. This alkaline waste is made up of water soluble salts and insoluble “sludges.” Most of the waste actinides and fission products are contained in the insoluble sludge, consisting mainly of hydroxides and hydrous oxides of iron, aluminum, and manganese. The rest of the waste is either in the form of a soluble crystalline salt cake or a nearly-saturated supernatant salt solution. This fraction contains about 95% of the fission product cesium and traces of other radionuclides.
