Autonomy is the guarantee of domestic nuclear power going out

“China’s nuclear power equipment manufacturing industry has gone through a 30-year history with the development of nuclear power, but the full-scale system to promote the localization of nuclear power equipment began with the April 2006 Dalian Red Rivers Nuclear Power Project equipment localization symposium.”5 On the 15th of the month, Chief Engineer Yan Yongbin of the China Federation of Machinery Industry stated at the 3rd Energy Forum in 2015 that the equipment manufacturing industry needs to adapt to the needs of internationalization and achieve equipment autonomy in order to promote the “going out” of nuclear power.

In the past ten years, under the strong support of the relevant state departments, under the strong leadership and organization and coordination of the National Energy Administration, with the active cooperation of nuclear power users, through independent research and digestion and absorption of advanced foreign technology, the domesticization of nuclear power equipment has achieved significant breakthrough.

Difficulties in the localization of nuclear power equipment to achieve a breakthrough

“From the nuclear island pressure vessels, steam generators, nuclear-stage pump valves, to conventional island turbine generators, we have a lot of supply conditions.” Yan Yongbin said, including the two major domestic nuclear island pump and nuclear DCS system Difficult points have also been through independent research or cooperation with foreign countries and other various forms, mastered the core technologies, and achieved independent integration.

“The localization rate of a large number of second-generation technology projects such as Hongyanhe, Ningde, Fuqing, Fangjiashan, Changjiang, etc. has gradually increased, and the current domestic production rate of the units under construction has reached about 80%.” Yan Yongbin believes that on this basis, China The self-developed third-generation nuclear power plant Hualong No. 1's localization rate of equipment can reach more than 85%. The introduction of the US Westinghouse AP1000 third-generation nuclear power unit puts forward higher requirements for equipment and materials. Through the digestion and absorption of the 12 equipment manufacturing technologies introduced in conjunction with the introduction of national key special projects to carry out a comprehensive technical research, in addition to the nuclear main pump, blast valve still needs to be further improved, has completed the prototype development of all key equipment AP1000 third-generation nuclear power technology The tests, tests, and appraisal work have created conditions for the development of China's AP series nuclear power units. The localization rate of CAP1400 equipment is expected to reach 80%.

Zhai Yongbin said that in recent years, equipment manufacturing has invested more than 40 billion yuan in technological transformation and research for nuclear power development. At present, China has built three nuclear power equipment manufacturing bases represented by the Northeast, Shanghai, and Sichuan, and has grown and expanded. A large number of supporting equipment and parts manufacturing companies that serve nuclear power.

The second generation of improved unit to the three generations of complete transition

“70% of the nuclear power generating units currently under construction are second-generation improved nuclear power units, but will be completed in the 13th Five-Year Plan period with the approval of the 30 million-kilowatt units under construction that have recently been approved by the state and the 30-million-kilowatt units under construction. From the second generation of improved units to the three generations of the unit's overall transition.” Yan Yongbin believes that China has formed an integrated production capacity, fully able to meet the development of nuclear power, localization, nuclear power development planning and the need for nuclear power to go out.

Zhai Yongbin said that nuclear power countries such as the United States, France, Japan, and Russia are not countries that are strong in nuclear power equipment manufacturing. China cannot rely on imported equipment to complete its transformation from a nuclear power to a nuclear power. The significance of localization of nuclear power equipment is very far-reaching. It not only grasps the initiative for the development of nuclear power, but also breaks the monopoly of foreign companies and greatly reduces the project cost. It can be said that without the localization of nuclear power equipment, there will be no major development of nuclear power in China today, and there will be no conditions for nuclear power to go out.

“The goal of nuclear power equipment going out is the goal and result of the effort, but it should be emphasized in the process of going out.” Yan Yongbin believes that the equipment manufacturing industry must be in the aspects of business philosophy, management level, product quality, standards and norms, and training of specialized personnel. To meet the needs of internationalization, it is necessary to gradually become an international company, so that it can become a new normal for nuclear power to go out.
