Abstract Scope |
One of the major issues in the design of MSRs is the significant corrosion of structural materials in FLiNaK. The corrosion in the form of selective dissolution of alloying elements in these molten salts depends on their redox potential, which in-turn depends on the type and amount of impurities present. There have been very few studies on the effect of oxide impurities, that may come with the salt or from the passive films formed on alloy surfaces, on this corrosion. In this study, corrosion behavior of selected Ni and Fe based alloys were studied in molten FLiNaK salt at 700 °C. Various oxide impurities such as Li2O, NiO, and Cr2O3 were added to baseline FLiNaK to understand their effect on this corrosion. This presentation will discuss our results on the effect of oxide impurities on the mode and extent of corrosion of candidate alloys in FLiNaK. |
