After 30 years of development, China's nuclear power scale and the entire industrial chain capacity have achieved leap-forward improvement, and engineering construction, production and operation and other fields have formed comparative advantages, which has attracted the attention of the international market. Through continuous capacity cultivation, the domestic equipment manufacturing industry has already possessed strong manufacturing capabilities, and has achieved a transition from catching up to surpassing it compared with foreign countries.
After 30 years of development, China's nuclear power has fully realized "four autonomy", namely independent design, independent manufacturing, independent construction and independent operation. The scale of nuclear power and the capacity of the whole industry chain have achieved leap-forward improvement, and the comparative advantages in the fields of engineering construction, production and operation have attracted the attention of the international market.
As far as the equipment field is concerned, China's nuclear power plants under construction are mostly second generation plus three generations of pressurized water reactor nuclear power plants, which are technologically advanced, safe and reliable. With the newly commissioned nuclear power plants, there is no gap between the technical indicators and foreign countries.
Through continuous capacity cultivation, the domestic equipment manufacturing industry has a strong manufacturing capacity. “Very strong” refers to the ability to fully meet or exceed market demand. Second, it refers to the nuclear power main equipment manufacturing has been realized in batch, and the manufacturing quality is stable. Third, it means that key materials and key process technologies have been localized.
As far as manufacturing is concerned, it can meet the needs of nuclear power construction and development. At present, China's nuclear power equipment manufacturing industry has formed three major nuclear power equipment manufacturing bases with Dongfang Electric, Shanghai Electric and Harbin Electric Group as the main body. China's one- and two-fold large forgings and reactor container manufacturing group. And a number of nuclear grade pump valves, internal components, control rod drive mechanism, main pipeline, nuclear grade cable and other ancillary equipment professional manufacturers.
As far as nuclear power plant equipment is concerned, the main gap between China and abroad is in the R&D innovation of equipment. China is pursuing catching up and surpassing, digesting core analysis techniques, continuously building key test devices, and launching three generations of pressurized water reactors with independent intellectual property rights, such as CAP1400, to develop a variety of four generations of nuclear power reactors, such as high temperature gas cooled reactors. , sodium cooled fast reactor, bismuth based molten salt heap.
In fact, there is still a lot of work to be done in manufacturing companies, including the joint development of technology reactors with independent intellectual property rights and the next four generations of reactor technology, jointly promoting equipment exports and forming the manufacturing capabilities of the three generations of nuclear island main equipment. Start with the combination of design and manufacturing, optimize the export structure, and improve the supply capacity of domestic raw materials.
