| 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. Corrosion of a given alloy also depends on the alloy composition. In this study, corrosion behaviour of selected Ni and Fe based alloys were studied in molten FLiNaK at 700 oC. Various impurities such as Li2O, CrF3, CrF2, etc. were added to baseline FLiNaK to understand their effect on this corrosion. The effect of added Li metal as a reducing agent was also studied to understand its effect in inhibiting corrosion in FLiNaK with different impurity levels. This presentation will discuss our results on the effect of impurities on the mode and extent of corrosion of the candidate alloys. |
