| Abstract Scope |
Resurgence in molten salt research for thermal energy storage has been driven by the growing interest from solar and nuclear industries. Concentrating solar power and next-generation fission and fusion reactor concepts utilize molten salts as thermal energy storage/transfer media. However, due to the corrosive nature of molten salts, especially when impurities are present, assessing long-term compatibility of materials in liquid salts remains a challenge. This is, in part, due to the lack of available long-term corrosion data and predictive modeling tools. In this work, we studied the dissolution of alloying elements in molten fluoride salts as a function of temperature and time, ranging from 550°C to 850°C, and up to 2000-hour exposures. The results from Cr and Fe dissolution are a step closer for assessing compatibility of alloys in molten salts.
