| Abstract Scope |
Electrochemical methods can be used to probe molten salt matrices so long as the electrodes can withstand the molten salt environment for prolonged periods. Boron-doped diamond (BDD) is expected to be resilient against harsh environments given its sp3-carbon structure. As such, BDD could be used to characterize dynamic molten salt fuel matrices and in situ corrosion control and monitoring in the core containment vessels. The present work is an expansion upon our previous findings for uranium(III/IV) in molten salts, including formal reduction potential, diffusion coefficients, electron transfer kinetics and stoichiometry, Gibbs free energy, enthalpy, and entropy using BDD. These measurements provided values comparable to expected literature values. Additionally, minimal corrosion or change to the BDD was observed using a range of topography and surface chemistry analysis techniques. Overall, this work advances the understanding of MSR chemistry while simultaneously proving the applicability of BDD as electrode material for harsh environments. |
