Title: Molten Salt Chemistry and Corrosion for Nuclear Applications

Molten salt has a wide range of applications in the nuclear field, serving as a coolant and/or liquid fuel for molten salt reactors, or as an electrolyte for the pyroprocessing of spent nuclear fuel. However, these applications are severely limited by material corrosion. Corrosion in molten salts is governed as much by salt chemistry (redox potential, metal-ion speciation, impurities) as by alloy composition and temperature.

In this talk, I will first discuss how different aspects of salt chemistry affect the corrosion of materials, including alloys and nuclear graphite, using various advanced techniques. I will then present the research conducted in our lab focused on controlling salt chemistry to mitigate corrosion, as well as salt chemistry monitoring. Together, these works greatly facilitate the resolution of molten salt corrosion challenges for nuclear applications.
