Abstract
A 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.
Claims6
A process for the treatment of fission waste comprising:
- (a) mixing a glass forming agent, a scavenging metal oxide, and a reducing agent with said fission waste;
- (b) melting said mixture and thereby forming a glass phase and a metal phase;
- (c) separating the two phases;
- and
- (d) cooling said glass phase and thereby forming a stable leach-resistant solid suitable for long-term storage of radioactive materials.
