| Abstract Scope |
Advanced nuclear power concepts designed for high efficiency impose remarkably harsh operating conditions, posing critical challenges to the applicability of 316L SS in next-generation nuclear reactors. In this study, a novel strategy to enhance thermal stability, mechanical strength, and radiation resistance of 316L SS was developed by doping nanotubes to form metal matrix composite (MMC). The study explored the individual effect of carbon nanotubes (CNTs), Ni-coated CNTs, and boron nitride nanotubes (BNNTs). The materials were fabricated by spark plasma sintering using functional powder. Thermal stability of the materials was evaluated by thermal treatment at various temperatures. Mechanical performance was assessed through tensile tests and nanoindentations. Radiation damage of the MMCs were evaluated after dual ion irradiation at 450 °C with a dose level up to 60 dpa. Additionally, the effectiveness of different types of nanotubes on material properties and alternative pathways for further refinement will be discussed. |
