Abstract Scope |
Chloride molten salts have mounting interests as abundantly available heat transfer fluids for advanced nuclear reactor technologies and concentrated solar energy applications. However, corrosion behavior of structural materials in contact with molten chloride salts needs to be further assessed to establish corrosion performance limitations. This presentation will discuss multi-modal characterization of Ni-based alloys, such as Hastelloy C-276 and Inconel 617, exposed to eutectic molten chloride salt mixtures. Changes in the speciation of the molten salt alongside the structural and chemical composition of corrosion products and remaining structural material at the salt-alloy interface will be captured using optical spectroscopy and electron microscopy techniques. Overall, the potential impact of this study is to expand on the knowledgebase of materials corrosion data for chloride molten salts, in turn enhancing potential corrosion mitigation strategies. |
