| Abstract Scope |
Compatibility of structural materials in molten halide salts has been a long-standing barrier in commercialization of these technologies, although there is extensive experience with operation of various MSR concepts for operation at temperatures between 650-700 °C. Operation at higher temperatures presents an even bigger challenge and extensive experimental efforts to evaluate materials compatibility are expensive and retard the development process. The current work aims to extend the applicability of a previously developed and successful experimental-computational approach to predict the corrosion behavior of multicomponent Fe- and Ni-based alloys in flowing molten chloride (KCl-MgCl2 and MgCl2) and fluoride (LiF-NaF-KF) salts between 600-800°C. Experiments were conducted to determine the dissolution rates of pure metals Cr and Fe in the aforementioned salts. These dissolution rates were employed to derive corrosion rates of these elements from the multicomponent alloys which were used to model the material degradation and predict lifetimes in thermal convection loops. |
