Conversion of radioactive ferrocyanide compounds to immobile glasses
Process for converting sodium nitrate-containing, caustic liquid radioactive wastes to solid insoluble products
Process for solidifying high-level nuclear waste Patent #: 4094809
AbstractA method is described for the treatment of fission waste. A glass forming agent, a metal oxide, and a reducing agent are mixed with the fission waste and the mixture is heated. After melting, the mixture separates into a glass phase and a metal phase. The glass phase may be used to safely store the fission waste, while the metal phase contains noble metals recovered from the fission waste.
