| Abstract Scope |
For molten salt reactors, highly purified chloride and fluoride salts are intended to be used as fuel, coolant, and heat transfer media with fluoride salts also being considered for fusion reactors. Purification of fluoride salts is done by passing hydrogen fluoride gas through the salt. Using ammonium bifluoride, it is possible to conduct fluoride purification in a safer manner than the traditional method while being cost effective for small to medium-sized batches of salt. Post purification characterization of salt is equally important to measure residual corrosive impurities such as moisture. Combustion analysis can characterize the moisture impurities in chlorides and fluorides which is important as moisture impurities contribute heavily to corrosion rates in molten salts. However, the technique is still not well understood. This presentation reports on methods and data-driven practices for purifying and characterizing impurities in fluoride salts. |
