Abstract
The invention provides an in situ method for protecting material exposed to molten salt, the method having the steps of supplying metal in a first nonreactive state to the molten salt to create a mixture; measuring a redox state of the mixture; and transforming the metal to a second reactive state when the redox state indicates corrosion of the material is about to occur. Also provided is a system for preventing corrosion of structural alloys in molten salt environments, the system having a vessel defining a void containing the molten salt; a voltammetry sensor inserted into the molten salt; a first cathode inserted into the molten salt; and a first anode inserted into the molten salt, whereby the cathode and anode are in electrical communication with an electrical power source.
