| Abstract Scope |
Advances in nuclear energy technology are vital to achieving net-zero emissions by 2050 and molten-salt reactors are a one of the promising up-and-coming Generation IV nuclear reactors. However, due to high working temperatures, corrosion on reactor parts become more prominent and container corrosion products become a part of the fuel salt system. These corrosion products can impact the speciation of the actinides. These changes in the local structure can alter the rheological properties, which defines the operational and safety parameters. Thus, an in-depth understanding of the influence of corrosion products on actinide speciation is crucial. Lanthanides are used as a surrogate in the initial work and Ni, Mn, Fe and Cr are used to represent corrosion products. These are reacted in the presence of alkali and alkali earth metal salts and salt mixes and analyzed using characterization techniques such as X-ray diffraction, spectroscopic (UV/Vis, Raman, FTIR) and microscopic methods. |
