| Abstract Scope |
Corrosion of structural metals by molten salts remains one of the principle challenges to the development of the Molten Salt Reactor (MSR). Studies of the processes by which corrosion occurs in molten salts is essential for the feasibility of these reactors; however, characterization of the corrosion process is hindered by the extreme environment, which makes in-situ monitoring of the exact mechanisms extremely difficult. Computational techniques are a promising pathway to help address these issues; however, higher length-scale models applicable to engineering systems must first be parameterized and validated by fundamental studies of the thermodynamics and kinetics of these systems. In this work, we present ab-initio thermodynamic calculations of model molten salts relevant to MSRs with applications including the study of phase stability at the metal-salt interface. Such atomistic studies are undertaken to further understanding of corrosion mechanisms, necessary for engineering corrosion resistant structural alloys. |
