| Abstract Scope |
Molten Salt Reactors (MSRs) and Concentrated Solar Power (CSP) plants require the development of pumps that can withstand the high temperature environment (between 500C to 800C), maintain resistance to corrosion occurring in the salt, and mitigate wear occurring at the material interfaces. New candidate materials are being examined for their corrosion resistance and tribological performance in fluoride salts like FLiBe and FLiNaK. Example materials being investigated include Cermet nickel-tungsten-carbide, Haynes 242, Haynes 282, and silicon nitride. This talk will present tribological data for friction coefficient and wear of the candidate materials while exposed in fluoride salts at prototypical temperatures in a Ball on Plate tribometer and Pin on Disk tribometer. This data will serve to provide a preliminary ranking of material performance in molten fluoride salt pump systems. |
