| Abstract Scope |
Electrochemical methods can probe fundamental aspects of molten salt matrices so long as the electrodes can withstand the molten salt environment for prolonged periods of time. Boron-doped diamond (BDD) is expected to be resilient against harsh environments, given its sp3-carbon structure. As such, BDD could potentially be used for characterization of dynamic molten salt fuel matrices, and potentially in situ corrosion control and monitoring in the core containment vessels. Characterization of europium(II/III) and uranium (III/IV) in molten LiCl-KCl included formal reduction potential, diffusion coefficients, electron transfer kinetics and stoichiometry, Gibbs free energy, enthalpy, and entropy of molten salt fuel systems using BDD. These measurements provided values comparable to expected literature values and, in general, little corrosion or change to the BDD was observed. Overall, this work advances the understanding of MSR chemistry while simultaneously proving the applicability of BDD as electrode material for harsh environments. |
