| Abstract Scope |
Reprocessing of used nuclear fuel can be accomplished through a high temperature molten salt-based method referred to as pyroprocessing. To incorporate ceramic fuels, UO2 is electrochemically reduced to a metallic form in a molten LiCl-Li2O salt. The reduction of UO2 is counterbalanced by the oxidation of dissolved oxygen in the salt to form oxygen gas. Most anode materials corrode simultaneously with the evolution of oxygen including platinum. Recently, iridium and ruthenium have shown promise as replacements for platinum. To reduce the amount of precious metals used in the anode, coatings of these precious metals on inexpensive substrates can lower the cost. Electrochemically produced precious metal coatings on various substrates and their performance as anodes for pyroprocessing will be presented.
