Abstract Scope |
The physical, chemical, and nuclear properties of fluoride salt eutectics make them appealing for use in Molten Salt Reactors. Molten fluoride salts, however, can be corrosive if their redox potential is not properly managed. Sparging the salt while molten with a mixture of HF and H2 has proven to be an effective method of purification; however, little is documented about the specifics of optimizing this method. To observe the effect of various system changes on the rate and quality of salt purification, and to observe the corrosion rates and patterns of various materials in a highly fluorinating molten salt environment, a facility was constructed to purify fluoride salts based on established methods. This work reports on studies aimed at optimizing methods, chemicals, and materials used during the hydrofluorination process with an eye toward commercial scale-up. |
