Abstract Scope |
Molten-salt reactors (MSR) are a proposed advanced nuclear reactor design that have significant benefits over traditional designs. However, the molten salts present new challenges in their corrosive nature, and as such, the reactions that occur between the salts and the metal alloys they interface with need to be studied. We are developing new in-situ analytical techniques to study the physical and chemical interactions that occur at the interface between alloys and molten salts. We have designed a boron nitride (BN) cell that houses a small amount of molten salt with electrodes inserted through the top and is placed in a custom furnace at a synchrotron beamline. We will present our progress in developing techniques to examine the corrosion that occurs between molten LiF-NaF-KF (FLiNaK) salt and a NiCr foil using a combination of x-ray absorption spectroscopy (XAS) and electrochemistry. |
