| Abstract Scope |
Used nuclear fuel can be reprocessed through a high temperature molten salt-based process referred to as pyroprocessing. A part of this process involves the electrolytic reduction of UO2 to uranium metal in molten LiCl-Li2O with oxygen evolution balancing the reaction at an anode. Most current anode materials, such as platinum, corrode concurrently with the evolution of oxygen which may contaminate the reduced product and increase the cost of pyroprocessing. Ruthenium and iridium have both been demonstrated as suitable anodes in this step, however, the large initial cost associated with their procurement is financially unattractive. Coatings and alloys with these precious metals can reduce the cost, making the process more economically feasible. Performance and characterization of precious metal-based coatings and alloys as anodes in the electroreduction step will be presented.
