[en] There is strong need to develop new advanced materials which have superior resistance against the exposure to high temperature, high radiation and severe corrosion environment. The nano-based or nano-assisted materials can be the candidates satisfying such demands, which will be one of the core technologies for advanced nuclear materials. In this research, the R and D plan for development of nano-based or nano-assisted materials is prepared based on in-depth technical analysis and preliminary experiments. This prior R and D planning will provide the strategic research subjects for successful future projects and reduce the risk of failure in developing nano-based or nano-assisted material
