A new batch of nuclear power projects have obtained "roadways" technology. China's nuclear power has entered the "fast lane"

under the general idea of "actively promoting" the development of nuclear power, China's nuclear power has entered the "fast lane". After the expansion of Qinshan Phase II and the commencement of Ling'ao phase II project, another batch of surpassing nuclear power projects were appropriately adjusted, such as Sanmen in Zhejiang, Haiyang in Shandong, Hongyanhe in Liaoning, Fuqing in Fujian, Fangjiashan in Zhejiang, Taohuajiang in Hunan and Changjiang in Hainan, followed by the approval of the national development and Reform Commission, and obtained the "road path of all day concussion and decline" for the preliminary preparation of nuclear power. The development of nuclear power has shown a momentum of accelerating

recently, it was learned from China National Nuclear Corporation that these new nuclear power projects, except for the Sanmen and Haiyang projects based on the introduction of third-generation nuclear power technology, a series of other nuclear power projects approved for construction have adopted the following methods: on the basis of introducing foreign technology, through digestion, absorption After re innovation, the international influence of China's plastic machinery industry continues to increase. China's independently designed "second generation plus" million kilowatt pressurized water reactor nuclear power technology will be used as the mainstream model of nuclear power plants in operation and under construction during the "Eleventh Five Year Plan" and "Twelfth Five Year Plan". According to the plan, by 2020, the installed capacity of nuclear power in China will account for more than 4%, and the investment is expected to exceed 450 billion yuan

Fuqing nuclear power project is located in Sanshan Town, Fuqing City. The master plan of the project is to build six million kilowatt nuclear power units, and phase I project will build two million kilowatt nuclear power units. The main project is planned to start construction in the near future. It is expected that the two units will officially aim to overcome the basic scientific problems and industrialization in the direction of high-performance separation membrane in 2013 and 2014, and put into commercial operation by using integrated key technologies and efficient complete equipment technology

Fangjiashan nuclear power project is the expansion project of Qinshan nuclear power station, the first nuclear power station in mainland China. It plans to build two million kilowatt pressurized water reactor nuclear power units, which are ready for construction by the end of this year. It is expected that the two units will be officially put into commercial operation at the end of 2013 and 2014 respectively. Qian Tianlin, deputy director of the comprehensive planning department of China National Nuclear Corporation, said in an interview that the Fuqing project will soon be poured with the first tank of concrete, and Fangjiashan will be ready for construction at the end of the year, which will be the two earliest projects. At present, the preparatory work for the Fangjiashan project is being carried out intensively

according to the preliminary plan, Hainan Changjiang nuclear power station, the first nuclear power project in Hainan Province, will start construction at the end of 2009, with a construction period of 58 months, and will be put into commercial operation at the end of 2014

in addition to the projects that have been approved, CNNC has also carried out the site selection of nuclear power stations in Putian, Fujian, Sanming, Western Zhejiang and xudabao, Liaoning

according to experts, pressurized water reactor is a relatively mature and universal reactor type in the world at present. At present, the relatively mature and advanced nuclear power technology in the world is the "second generation plus" million KW nuclear power technology. The mastery and application of this technology is the overall embodiment of the independent design ability of China's nuclear power development in the past 30 years. It marks the significant shortening of the gap between China and the international nuclear power technology level, and also provides a strong technical support for the introduction, digestion and absorption of the subsequent three generations of nuclear power technology

"at present, more than 200 design improvements including 14 major improvements in Ling'ao phase II project have been basically implemented, which means that the 'second generation plus' level of China's independent design has been solidified, and the subsequent Hongyanhe, Fuqing, Fangjiashan and other projects are mature applications of this technology." Xu Li, party secretary and deputy general manager of CNNC China Nuclear Power Engineering Co., Ltd., said so. In the Ling'ao phase II project, CNNC China Nuclear Power Engineering Co., Ltd., as the general contracting Institute of design, cooperated with the China Nuclear Power Institute under CNNC, and with the strong support of nuclear power owners, jointly practiced the process of introducing, digesting, absorbing and upgrading international second-generation nuclear power technology. This experience made him full of confidence in several nuclear power projects in the future

the 13 scientific research institutes under CNNC group have formed a complete set of nuclear industry scientific research system, which is of great significance to the research and development of nuclear power related technologies. As a comprehensive basic scientific research institute, CNNC China Academy of atomic energy has relatively complete scientific research equipment and means, which provide important support for the theoretical demonstration in the field of nuclear power design. CNNC Nuclear Power Institute has more than 100 disciplines and disciplines and more than 90 research laboratories in nuclear power research and development, including three national key national defense science and technology laboratories, and has successively built six nuclear facilities, including high-throughput reactors, known as "China's reactor Valley". On the basis of the second generation R & D platform, the third generation R & D platform has begun to actively raise funds, which will play a greater role in the R & D of China's third and fourth generation nuclear power technology

How can China's nuclear power achieve scale development on the premise of ensuring nuclear safety? Nuclear power experts believe that a clear technology roadmap is very important to achieve the scale development of nuclear power, which can be summarized as "application generation, research and development generation, pre research generation", and promote the continuous development of China's nuclear power technology

first of all, with reference to foreign experience in localization, standardization and batching on the basis of mature technology, we should speed up the scale construction of "second generation plus" nuclear power units, continue to improve the design of "second generation plus" and actively promote China's million kilowatt nuclear power plants with fully independent intellectual property rights to land abroad as soon as possible

secondly, accelerate the pace of introduction and absorption of the third generation pressurized water reactor technology. According to the national deployment, Sanmen Nuclear Power Co., Ltd., a subsidiary of CNNC, has completed a lot of preliminary work, creating good conditions for the demonstration project of building the world's first third-generation pressurized water reactor

at the same time, actively participate in the research and development of international fourth generation nuclear power plants. The China experimental fast reactor, undertaken by the China Academy of atomic energy under CNNC, is expected to be completed in 2010

at present, there are more than 400 nuclear power stations in the world, with a total installed capacity of 370million kW, and the annual power generation accounts for 17% of the total power generation in the world. China has built three nuclear power stations in Qinshan, Daya Bay and Tianwan, with a total of 11 units and 9million kW, accounting for about 2% of the total installed power generation capacity of the country
