| Abstract Scope |
Nuclear energy is a dependable alternative to fossil fuel-based energy sources. However, concerns with safety, efficiency and environmental impact must be addressed. Next generation reactors aim to answer these concerns with materials that offer superior performance and adequate safety properties. Molten Salt Reactors (MSR) offer improvements over conventional light water reactors (LWR) that include passive safety measures, higher run temperatures, greater specific power and better compatibility with fast neutrons. However, molten salts are known to corrode conventional containment materials such as stainless steels. In this work nickel alloys will be tested for corrosion resistance. Tubes of nickel alloys (Inconel) as well as conventional stainless steels (316) will be filled with a eutectoid NaCl-MgCl2 salt, sealed under vacuum and placed in a furnace for various durations at typical MSR temperatures. After heat treatment the tubes will be cut in cross-section and the corrosion layers will be analyzed with SEM/EDS. |
