Nuclear reactors have been evolving from the 1940’s to the present with generation IV nuclear reactors being the latest in this evolution. There are several generation IV options/designs including the molten salt reactor (MSR), a small and modular reactor that reduces risks. The molten chloride fast reactor (MCFR) is one of the design options for an MSR. This reactor design requires structural materials with favorable properties, including corrosion resistance, in the 700 – 900 ˚C temperature range. In this project, the corrosion behavior of commercial and experimental Ni-based superalloy candidates in molten chloride salts was studied. The alloys were subjected to different exposure times at an elevated temperature in an inert atmosphere. The post-test samples were characterized using different methods. This talk will discuss the results and implications for alloy design for this application.
