Molten salts have garnered a resurgence of interest due to their favorable use in energy applications such as advanced nextgeneration nuclear power plants. These include fluid-fueled molten salt reactors (MSRs) which employ fluoride or chloride salts, solid-fueled reactors which employ salt as a hightemperature coolant such as the fluoride-salt-cooled high temperature reactor (FHR), and fusion reactors such as the affordable, robust, compact (ARC) reactor which uses 2 LiF-BeF 2 as both a coolant and a tritium breeding blanket. Molten salts provide high volumetric heat capacity and a wide range of thermal stability that allow reactors to deliver a larger fraction of their heat at higher temperatures compared with traditional designs. This increase in heat-to-electricity efficiency, along with the possibility of diverse energy products at higher temperatures, enhances the economic competitiveness of salt-based nuclear energy systems. Additionally, the ability to operate at nearly atmospheric pressure enables design of passive safety systems and inherent safety features which help meet high safety standards with greater simplicity of design and, consequently, with potentially lower development costs and shorter development timelines. the density, viscosity, thermal expansion, specific heat, and others has been the focus of a number of studies. Electroanalytical studies have sought to characterize ionic transport as well as the liquidus in LiF-BeF 2 systems. Additional studies have focused on measuring the atomic structure of molten salt candidates and their corrosive effects on structural materials. With the vast possibilities of salt compositions, predictive modeling can alleviate experimental bottlenecks associated with characterizing new salt mixtures. To successfully ascertain the physical characteristics of molten salts using simulations, their atomic structure needs to be measured experimentally to validate the assumptions required in simulations.
