The picture shows the follow-up CAP1000 nuclear power project part of the main pump purchase contract signing site. State Nuclear Electric hosting company Cheng, Shenyang Blower Group AP1000 hosted the 18th meeting of the leadership of IPT nuclear power main pump, held recently in Shenyang, Liaoning. During the meeting, State Nuclear Engineering Co., Ltd. signed the "Procurement Contract for Main Pumps of Subsequent CAP1000 Nuclear Power Projects" with Shenyang Drum Group Nuclear Power Company and Harbin Electric Power Equipment Company, with the total contract value exceeding 2.5 billion yuan. The signing is the key symbol of CAP1000 shielded motor main pump localization, and it is also an important measure to implement the national nuclear power development strategy. Wang Binghua, vice chairman of the State Nuclear Power Technology Corporation, Sun Wenke, general manager of the State Nuclear Power Engineering Corporation, Su Yongqiang, chairman of the Shenyang Drum Group, and Gong Jingyao, chairman of the Haadian Power Group, The leaders of the relevant units attended the signing ceremony. Large-scale advanced nuclear power technology with independent intellectual property rights has always been the dream of China's energy and nuclear power industry. To this end, the state introduced the world's most advanced AP1000 third-generation PWR nuclear power technology and carried out the first batch of unit construction in Sanmen, Zhejiang and Haiyang in Shandong as the basis for the independence of the third generation of nuclear power. As the core equipment of nuclear power plant, localization of the main pump is the key to the success of the project. To this end, the State Nuclear Power signed the main pump orders formulated a "16 +2" program, that is, 16 main pump provided by foreign manufacturers, 2 standby pump by the Chinese manufacturers responsible for the production. The nuclear main pump is the heart equipment of the "primary circuit system" which is in direct contact with the reactor. It is the core equipment of nuclear safety level, quality level and seismic class I. The design life is 60 years, and the technical difficulty is high and the reliability requirements are high. The most technologically advanced pump products have drawn much attention from all parties due to their safety, reliability and advanced nature. They have a significant impact on the large-scale advanced PWR nuclear power technology developed independently by China. At present, the main pump project undertaken by Shenyang-Shenyang Group has overcome many cutting-edge technical problems such as hydraulic design, safety analysis, stress calculation, rotor dynamic analysis, bearings, materials and technology, and has completed the solution to the technical key, spare parts manufacturing and testing center Construction and other work. The nuclear power main pump hydraulic components provided to foreign manufacturers have all been completed and passed the ASME certification. The additional 2 main pumps have already entered the assembly phase. Through the development of the first batch of national-made nuclear power main pumps in the country, Shenkui Group has continuously improved its capabilities in R & D, design, equipment manufacturing, system construction and operation and management and has trained a large number of professional and technical personnel. As the main contractor of the main pump purchase contract for some of the CAP1000 nuclear power projects, Shenyang Drum Group said it will mobilize all resources and give full support to the successful completion of the main pump development task for the subsequent CAP1000 nuclear power project.
