| Abstract Scope |
Molten salts hold immense promise for various energy applications, including the use as electrolytes in batteries, thermal energy storage and transfer media, fuel and solar cells, pyro-processing of spent nuclear fuels, and coolants or fuel solvents in molten salt reactors. A critical challenge across these technologies is the corrosion of structural alloys, typically stainless steels and Ni-Cr-based alloys. Addressing this challenge requires a mechanistic understanding of how impurities in molten salts interact with metals. This talk is focused on dissolved moisture in fluoride and chloride salts. Through multiscale modeling and simulations, including ab initio molecular dynamics, kinetic Monte Carlo, and phase field, we will show how pure salts interact with structural alloys, how H2O behaves and interacts with structural alloys in molten salts, how trace impurities influence the corrosion kinetics and morphological evolution in structural alloys, as well as the implications of these modeling insights on mitigating molten salt corrosion. |
