| Abstract Scope |
Facilitation of robust and economical design of molten salt reactor systems requires fundamental understanding of the structure and speciation of salts and metals in and near molten salt environments. We use X-ray absorption spectroscopy (XAS) to investigate the effect of metal concentration and temperature on local coordination environments and chemical structures of metal species (Nickel) in Zinc chloride based molten salt systems. XAS studies complemented by optical studies enable a direct correspondence between UV-Vis peak shape and coordination geometry and number, determined by EXAFS. Such knowledge of speciation of metals and radiation-induced nanoparticles in molten salt environments provides a critical understanding necessary to predict and control physical and chemical properties of molten salts and corrosion mechanisms in molten salt systems. This work was supported as part of the Molten Salts in Extreme Environments, Energy Frontier Research Center, funded by the U.S. Department of Energy Office of Science. |
