| Abstract Scope |
Molten salt reactors (MSRs) are one of the most popular Gen IV concepts currently under development, garnering significant interest from both the private sector as well as the research community. One of the major challenges to the development of MSRs is the selection of a material for in-core use which has good mechanical properties at high temperature (700C and above), tolerance to radiation damage, and resistance to corrosion in the highly aggressive fluoride molten salt environment. In this work, we present the design of a metallic multilayer composite for MSRs based on the Incoloy 800H/Ni—201 system with the intent of achieving these properties. In this presentation, we will discuss the as-processed microstructure along with the long-term stability of the coating-substrate composite. Implications for use in fluoride molten salt reactors will be discussed. |
