| Abstract Scope |
Newcleo is developing Lead-cooled fast reactor (LFR) Small Modular Reactors (SMRs) for next-generation nuclear energy. LFRs face challenges with materials that withstand high temperatures and corrosive liquid lead. This study explores novel coating techniques—such as PVD, CVD, thermal spray, laser cladding, and weld overlay with AFA steel—to enhance material performance and corrosion resistance. Coated materials were tested under simulated LFR conditions (up to 600°C), evaluating their ability to prevent lead penetration and maintain integrity. Preliminary tests in dynamic molten lead environments and ionic irradiation show promising results. The presentation highlights the performance of various coatings, including FeCrAl, ceramic nitrides, TiN, and alumina-based materials. These coatings, applied in different thicknesses, demonstrate potential for improving the durability of LFR components in extreme environments, supporting the development of safer, more efficient nuclear reactors. |
