Abstract Scope |
Because of their high thermal stability and low vapor pressure, molten fluoride salts are considered as coolants for use in Gen IV nuclear reactors. One of the challenges of using molten salts as coolants is their corrosivity to structural alloys due to the presence of impurities which directly/indirectly drive corrosion. To minimize the corrosion issues in molten fluoride environments, salt purification is extremely important. To date, the most common purification method has been the use of a mixture of hydrogen and hydrogen fluoride (HF). However, due to safety concerns involving the use of HF, other purification approaches are being investigated. In this talk, several salt purification methods will be evaluated and compared. As an ultimate test of salt purity, 316H stainless steel specimens were exposed to molten fluorides purified by nonconventional approaches.
