| Abstract Scope |
The corrosion of structural alloys by molten salt is a major concern for molten salt reactors. To help understand and potentially mitigate such corrosion, we have developed a model that predicts this corrosion at the mesoscale. Our electrochemical corrosion model uses the phase field method implemented in the MOOSE framework to predict the transport of alloying elements into salt, including fast diffusion along grain boundaries. It has been validated for the corrosion of NiCr alloys by FLiBe and is now being extended to Alloy 316H and FLiNaK. It has been applied to investigate the impact of coatings and the impurity concentration in static salt experiments. We are currently adding the impact of stress and radiation on the corrosion and carrying out new experiments to validate these additions to the model. |
