| Abstract Scope |
Recent advancements have revitalized interest in molten salts as heat transfer fluids and reaction media in energy systems such as molten salt reactors (MSRs), concentrating solar power plants, and batteries. Structural alloys exposed to molten salts undergo morphological changes that might result in degradation. MSRs will expose materials to molten salt containing numerous fission products that may act as oxidants, further accelerating the corrosion of the alloys. One such corrosive species is EuCl3. We examined the impact of added EuCl3 on the morphological and chemical evolution of Ni-20Cr alloy in molten LiCl-KCl eutectic using a multimodal characterization approach combining synchrotron X-ray nano-tomography, X-ray absorption spectroscopy and transmission electron microscopy. This helped us understand the corrosion mechanisms occurring at the metal-salt interface in the presence of EuCl3 over time, revealing more spatially-resolved details at the sub-micron level. A detailed observation of morphological transformations in Ni-20Cr alloys over varying temperatures is discussed. |
