The world's first AP1000 nuclear power plant is waiting to break its cocoon
there is no doubt that the commencement ceremony of Sanmen Nuclear Power Phase I project in Zhejiang Province will earn the world's attention
why do you say so
first, the world's most advanced third-generation nuclear power technology AP1000 is the first time from technical theory to reality after the United States "married" China. The subsequent construction and operation of Sanmen Nuclear Power Station will affect the application and trust of AP1000 nuclear power technology worldwide. Second, Sanmen Nuclear Power Station is a wind vane for China, a large nuclear power application country, to use nuclear power technology, and ecological restoration is also a window to observe China's energy structure adjustment. Third, Sanmen Nuclear Power Station is the first carrier of China's third-generation nuclear power technology AP1000 and its equipment manufacturing autonomy, which will test China's technology and manufacturing capacity
Sanmen Nuclear Power Station is located in maotoushan Peninsula, Jiantiao Town, Sanmen County, Taizhou City, Zhejiang Province. It is reported that the Sanmen Nuclear power project plans to build six nuclear power units with a single unit capacity of 1.25 million in three phases, aiming to further strengthen the exchange and communication of Watts in the development of the global plastic industry. Two units will be built in phase I, and unit 1 will be completed and put into commercial operation in November 2013; Unit 2 is planned to be completed and put into commercial operation in September 2014
Sanmen Nuclear Power Co., Ltd. of China Nuclear Power Group will be fully responsible for the construction, commissioning, operation and management of the station. Gu Jun, general manager of the company, said, "the AP1000 nuclear power plant will be built by the modular construction method. The whole unit has 108 structural modules and 70 equipment modules. The modular construction method is like building blocks, which can manufacture multiple modules at the same time. After the module is manufactured, the modules can be assembled on site. This can save a lot of time."
the significance of the construction of Sanmen Nuclear Power Station for China's energy structure adjustment and energy conservation and emission reduction, Chen Hua, director of the nuclear power department of China National Nuclear Power Corporation, said: "compared with the million kilowatt ultra supercritical coal-fired generating units with the same power generation capacity, Sanmen Nuclear Power Phase I project can reduce the transportation volume of 5million tons of high-quality power coal every year, and reduce the emissions of 11490 tons of sulfur dioxide, 19088 tons of nitrogen oxide and 1345 tons of soot."
it is reported that from the perspective of probability analysis, the safety of AP1000 nuclear power technology is 100 times higher than that of China's current second-generation plus nuclear power technology. In terms of economy, the service life of AP1000 nuclear power plant is 60 years, while the second generation plus is 40 years. Lin chengge, a member of the expert committee of the national nuclear power technology company, which is the platform for the introduction of AP1000 nuclear power technology, said: "the biggest feature of AP1000 nuclear power is its passive safety system. The design of this system can make this the first nuclear power plant in the recycled plastic zone held continuously in the form of an exhibition in China, and its safety and operability reach the world's advanced level, and can enhance the control of cost and quality."
at the same time, with regard to the localization of AP1000 nuclear power equipment, which has attracted much attention, Xu Lianyi, member of the expert committee of the National Nuclear Power Technology Corporation, said: "the localization proportions of the first four units of Sanmen Nuclear Power Plant are 30%, 50%, 60% and 70% respectively. Through the localization of these four units, China can master the key technologies of the main equipment of AP1000 and basically realize localization from the fifth unit."
Sun Qin, deputy director of the national energy administration, previously said that the construction of onshore nuclear power plants in China will continue to be dominated by AP1000 reactor types. In the future, new nuclear power plant projects, including coastal nuclear power plant projects, will also be dominated by AP1000 series reactor types
China's "national nuclear power medium and long term development plan (2005 ~ 2020)" proposes that by 2020, the target of 40 million kw of installed capacity for nuclear power operation and 18 million KW under construction should be achieved. However, during the national two sessions, Zhang Guobao, director of the national energy administration, said publicly that by 2020, China's nuclear power installed capacity may exceed 100million kW
Sanmen Nuclear Power Station will make great strides forward in this round of nuclear power construction, taking the role of the pioneer in the application of AP1000 nuclear power technology
