Abstract Scope |
The performance of various materials in MSRs such as structural alloys, graphite moderator, fuel components etc. rely heavily on the redox potential of the molten salt, which in-turn depends on the type and amount of impurities present in the salt. The amount and type of impurities in the salt affects the corrosion behavior of structural materials, chemical stability of graphite, and more. In this study, the effect of various impurities such as oxides, fluorides, and various active elements on the redox potential of molten FLiNaK was systematically studied. The effect of these impurities on the corrosion behavior of selected Ni and Fe based alloys, mechanical properties of some of these alloys, as well as the chemical behavior of nuclear grade graphite were also studied in molten FLiNaK at 700 °C. This presentation will discuss our results to show the impact of impurities on various structural materials in molten FLiNaK. |
