There are two main third-generation nuclear power technologies in China, namely "Hualong One" and "Guohe One". Different from Guohe One, Hualong One nuclear power technology is the result of joint research and development by China National Nuclear Corporation and China General Nuclear Power Group. Before Hualong One, CNNC already had ACP1000 and CGN had ACPR1000 technology as the basis. Hualong One is the two It is a fusion of technologies.
If Hualong One, jointly developed by China National Nuclear Corporation and China General Nuclear Power Corporation, focuses on the international nuclear power market, then Guohe One is more like focusing on the domestic market. China’s third-generation nuclear power technology line is “one main, one auxiliary". The State Power Investment Group, which developed Guohe No. 1, was first established to introduce overseas nuclear power technology, such as the AP1000 nuclear power plant mentioned above. But starting in 2008, State Power Investment Corporation began to independently develop the third-generation nuclear power technology "Guohe No. 1", and this overseas nuclear power investment company has truly become a real nuclear power company.
Guohe No. 1 is also known as CAP1400. Although its research and development took 12 years, it is the integration of the 50 years of development results of several generations of nuclear power in our country. The units and technical personnel involved in the research and development cover the whole country, led by Shanghai Nuclear Engineering Research and Design Institute - Zheng Mingguang serves as the chief designer. The maximum power of the Guohe-1 nuclear power unit reaches 1.5 million kilowatts. It is the largest nuclear power unit in my country at present, with a maximum service life of 60 years. Its research and development has obtained 6,513 property rights results. It can be said that Guohe-1 has filled the domestic first The gap in third-generation nuclear power technology has enabled domestic third-generation nuclear power technology to move from the laboratory to market industrialization.
On September 28, 2020, the State Power Investment Corporation officially announced that the research and development of the domestic third-generation nuclear power technology Guohe No. 1 was completed. As one of my country’s sixteen major science and technology projects, it marks that our country has completely overcome the With third-generation nuclear power technology, China Nuclear Power has also successfully leapfrogged from the second generation to the third generation, laying the foundation for the scale of my country’s third-generation nuclear power plants.
