The US government has imposed sanctions on Chinese companies twice this year, first on May 16.HuaweiAfter being listed in the list of entities, during the period of mediation, the United States announced at the end of June that it would relax its sanctions against Huawei. However, it has recently re-admitted that the US Department of Commerce has expressed its disappointment that it is unlikely to relax the sanctions.

The second wave is aimed at four high-performance computing companies in China, including Zhongke Shuguang, Tianjin Haiguang, Chengdu Haiguang Integrated Circuit, Chengdu Haiguang Microelectronics Technology, and Wuxi Jiangnan Computing Technology Research Institute.

Now this time is aimed at China’s nuclear power company.CGNPC is China's largest, the world's third largest nuclear power company and China's second largest clean energy enterprise.As of the end of July 2019, China General Nuclear Power Group owns 23 nuclear power generating units with an installed capacity of 25.39 million kilowatts; 5 nuclear power units under construction with installed capacity of 6.35 million kilowatts; and wind power installed capacity of 12.39 million kilowatts, solar photovoltaic power generation. The project has a holding capacity of 4.22 million kilowatts in the holding of the aircraft, and overseas new energy is in operation with a holding capacity of 13.38 million kilowatts.

However, even if the United States sanctions China Nuclear Power, it will not have any impact on the development of nuclear power in China. Before that, China spent money on the AP1000 nuclear power plant technology of Westinghouse Electric, but according to the agreement signed by China and the United States, China absorbed and improved on the basis of AP1000. The domestic third-generation nuclear power technology - "Guohe No. 1" (CAP1400), through the re-innovation of a large-scale advanced passive pressure water reactor nuclear power model with independent intellectual property rights and greater power, the power reached 1500 MW, successfully Exceeding the technical threshold of 1350 MW set by the AP1000 technology introduction contract.

According to Qian Zhimin, chairman of the State Power Investment Corporation, “Guohe No.1” relies on the research results of major national science and technology projects led by the national power investment. So far, its pressure vessels, steam generators, control rod drive mechanisms, and blasting valves The main equipment has been fully localized; key materials such as large forgings, steam generator 690 heat transfer tubes, nuclear grade zirconium materials, nuclear grade welding materials, etc. have been basically localized; independent advanced nuclear fuel shaping components have been successfully developed; 11 pumps, The prototype of the 10 types of valve engineering was basically developed. As a result, its comprehensive performance, especially economical, is better than AP1000, and the subsequent batch production cost can be reduced by more than 10%.

In addition to Guohe No.1, China’s third-generation nuclear power technology is also Hualong No.1, which is responsible for CGNPC. On July 14th, Hualong No. 1 World First Demonstration Project Fuqing Nuclear Power Unit 5 Completed, the world's first pile height of Hualong No. 1 reached 73.98 meters, becoming the “new landmark” of Fuqing nuclear power station. This laid a solid foundation for the hot test and charging of the unit, and also accumulated valuable experience for the follow-up of Hualong Unit 1.
