| Abstract Scope |
Nuclear energy is a reliable replacement to fossil fuels energy sources. Concerns about safety and environmental impact are being addressed in next generation reactors, wherein materials that offer greater performance and safety properties are investigated. Molten Salt Reactors (MSR) offer improvements over conventional light water reactors (LWR), which include passive safety measures, higher operation temperatures, greater specific power and greater compatibility with fast neutrons. One main obstacle with molten salts is that they are known to corrode containment materials such as stainless steels. In this work nickel superalloys will be tested for corrosion resistance. Tubes of nickel alloys, Haynes 244 and Inconel, as well as 316 grade stainless steel will be filled with a eutectoid mixture of NaCl and MgCl2, sealed under vacuum and placed in a furnace at typical MSR temperatures for various durations. After heat treatment the corrosion interfaces and products will be analyzed with SEM/EDS. |
