CX-022590: Novel Single and Polycrystalline Diamond-Based Spectroelectrochemical Sensors for Advanced Understanding of Radioactive Molten Salt Chemistry

The University of Nevada, Las Vegas (UNLV), in collaboration with Pacific Northwest National Laboratory (PNNL), proposes to advance fundamental understanding of radioactive molten salt chemistry through determination of important redox and thermodynamic properties of nuclear fuel Uranium (U-238) and Plutonium (Pu-239) in both chloride- and fluoride-based molten salts. Boron-doped diamond (BDD) electrodes will be developed for spectroelectrochemical measurements in various molten salts. In the first phase of this project, corrosion/fouling of the BDD electrode surface will be studied.
