According to the information available, the scale of the under-construction of China's nuclear power is the largest in the world. The three generations of heap are the independent "Hualong No.1", AP1000, CAP1400 and EPR1000. AP1000 nuclear power technology is China's third-generation advanced nuclear power technology imported from Westinghouse Co. in 2006 by China. After the introduction of this technology, it is mainly through the national nuclear power technology company (hereinafter referred to as "national nuclear power") to digest and absorb and then innovate to form an independent nuclear power brand. This technology is considered as one of the mainstream technologies of China's nuclear power and will be used by more new nuclear power plants in the future, especially inland nuclear power. However, there are some technical problems that need to be solved before the AP1000, and the construction period is extended by a few degrees. Yesterday, the national nuclear power technology company and the United States Westinghouse Electric Company, Curtis Qian Chengyu actually meal track trace? P1000 Gen III nuclear reactor reactors coolant shielding main performance test and post-test of the main pump This marked the solution to the biggest problem plaguing the construction of the first heap of three generations of nuclear power in the world. It is reported that Zhejiang Sanmen NPP is the world's first application of AP1000 site, the first two units of Unit 1 will arrive on December 31 before the installation on-site commissioning. Wang Zhongtang, general manager of nuclear technology introduced, the final performance test by Curtis Qian Chengyu?

MD) completed within the factory , Verified that the main pump successfully operated for more than 1600 hours under various operation conditions of the AP1000 nuclear power plant, including more than 600 start-stop cycles. It is reported that the main pump design and manufacturing technology is the United States EMD company on China AP1000 technology transfer one of the main content. At present, Shenyang Drum and Harbin Electric have basically mastered the main pump manufacturing technology through the digestion and absorption of technical documents, software and sub-contracting, and can be used for subsequent AP1000 projects.
