| Abstract Scope |
Molten salt reactors represent a promising candidate technology that utilize salts as circulating media for both reactor coolant and fuels. However, corrosion of materials subjected to molten salts can be induced by oxidizing fission products, which pose significant challenges for structural alloys. To that end, this study investigates the corrosion behavior in Ni, Ni-20Cr, and V systems exposed to LiCl-KCl eutectic salts in the presence of EuCl3 by employing advanced characterization techniques such as scanning transmission electron microscopy imaging (STEM), elemental mapping, and fine structure analysis. The research aims to elucidate primary corrosion mechanisms, including intra- and intergranular attack, Cr-dissolution, crystallographic corrosion and the impact of EuCl3 on corrosion pathways. Experimental procedures include high temperature corrosion tests, in-situ optical spectroscopy for real-time salt chemistry monitoring, and post-corrosion analysis using ICP-MS. These findings enhance the understanding of material performance to corrosive salts; laying groundworks for corrosion-resistive development for advanced reactor materials. |
