| Abstract Scope |
Advanced nuclear reactor technologies, with the use of liquid metals or molten salts, have the potential to improve safety, efficiency and cost competitiveness of nuclear energy. However, significant challenges exist in the design, selection and qualification of structural materials due to the limited knowledge on the key parameters governing corrosion induced degradation mechanisms and thereby material lifetimes. In the present work, the role of alloy thermodynamics and kinetics in material degradation during exposures in high temperature corrosive environments will be discussed combining experimental and computational methods. The fundamental role of coupled thermodynamic-kinetic processes on the environmental degradation of various material/coolant systems: Ni-based alloy/molten salt; Fe-based alloy/liquid sodium and Zr-based alloy/ liquid PbBiSn will be presented. |
