From the completion of the first military reactor to the approval of the third generation nuclear power unit in July 2019, nuclear power in China has experienced long-term development and entered a period of nuclear power restart. This paper mainly describes the nuclear power technology route, the localization rate of nuclear power equipment and the related development plan at different stages of development. The development of nuclear power industry in China is the struggle history of nuclear power industry and manufacturing industry. The localization rate of nuclear power equipment is constantly improving in the limited nuclear power projects. In the face of the technical difficulties encountered in the process of localization of nuclear power, China's nuclear power from the design institute to the manufacturer share the risk, break through the predicament, and realize the localization of three generations of technology. In the face of more advanced nuclear power technology demand, the nuclear power industry should establish a sustainable advanced industrial equipment manufacturing supply management system according to the technical needs.
