Abstract Scope |
As the demand for electrical power constantly rises, which is further exacerbated by the need to reduce the carbon footprint of current technologies, nuclear power is a proven solution to the problem. Although current nuclear power technology currently leaves behind legacy waste, next generation reactors (Gen-IV) utilize molten salts as reactor coolant to provide a much cleaner energy source. Although the higher operating temperature of the molten salt reactors (MSR) allows for a higher output of electrical energy, one issue stands in the way of moving forward with MSR’s: corrosion. Since molten salts are highly corrosive to the commonly utilized iron-based structural materials, new structural materials are being investigated. Nickel based alloys show significantly higher corrosion resistance to molten salts, so this paper investigates the corrosion rates of Inconel 600 and compares to pure nickel using Linear Polarization Resistance, Tafel, and Electrochemical Impedance Spectroscopy. |
