nuclear powerThe unit is composed ofreactorAnd its supportingturbogeneratorGroup and the basic power generation unit composed of systems and facilities required to maintain their normal operation and ensure safety.
As of May 2024, China has 26 nuclear power units under construction, with a total installed capacity of 30.3 million kilowatts, ranking first in the world in terms of both the number of nuclear power units under construction and the installed capacity.[5][7]

1. A total of 11 nuclear power units have been built and put into operation in China, with a total installed capacity of 9.1 million kilowatts;Among the 10 approved nuclear power projects, there are 28 sets of nuclear power units, of which 24 sets have been started.Recently, an official from the National Energy Administration revealed that China is adjusting its medium - and long-term nuclear power planning for 2020. By 2020, China's nuclear power installation target is conservatively estimated to be about 70-80 million kilowatts.
2. China'snuclear powerThe development technology route planning is to focus on localization, organize digestion and absorption in a unified way, realize independence after re innovation, and catch up with the world's advanced nuclear power level.Before the three generation nuclear power technology has been fully digested, absorbed and mastered, we will build nuclear power plants of appropriate scale on the basis of existing improved nuclear power technology.The localization rate of China's independent second-generation semi nuclear power technology CPR1000 is about 70%, which will be improved in the future.The third-generation nuclear power technology will be the leading role in China's nuclear power development in the next 20 years,ZhejiangSanmenheShandong Haiyang Nuclear Power StationA total of 4 units have implemented the independent digestion, absorption, re innovation and construction of the introduced third-generation nuclear power technology AP1000. It is expected that a third-generation nuclear power plant will be built around 2013, and the localization rate of third-generation nuclear power technology AP1000 units will gradually increase.[1]
3. The mainstream technology of global nuclear power development is pressurized water reactor (accounting for about 80%). The main players of pressurized water reactor technology are Westinghouse and Areva (accounting for 30% respectively). The completed pressurized water reactor nuclear power plants in China belong to the second generation nuclear power technology.
4. As the third generation mainstream nuclear power technology introduced into China, the AP1000 was developed by Westinghouse on the basis of its AP600 and finally approved by the Nuclear Regulatory Commission of the United States.Our AP1000 relies on the project for its first construction in the world.
5. EPR is developed by Areva and first built in Finland.The construction of two sets of EPR in Taishan, Guangdong, means that another three generation mainstream technology, EPR technology, has actually entered China.[2]
6. In 2021, China had 53 operating nuclear power generating units with an installed capacity of 54.63695 million kilowatts, ranking third in the world in the number of operating nuclear power generating units after the United States and France.[3]
7. As of June 2022, China has 54 nuclear power generating units in operation, 23 nuclear power generating units under construction, and the number of nuclear power generating units under operation and construction is the second in the world.[4]
General development trend

oneChinaWe are stepping up efforts to adjust the energy structure.It is urgent to actively develop nuclear power, wind power, hydropower and other clean and high-quality energy.China's energy structure is still dominated by coal, and the proportion of clean and high-quality energy is low.
2. Completed and under construction in Chinanuclear power plantThe total installed capacity is 8.7 million kilowatts. It is estimated that China's nuclear power installed capacity will be about 20 million kilowatts by 2010 and 40 million kilowatts by 2020.By 2050, according to the estimates of different departments, China's nuclear power installed capacity can be divided into three schemes: the high scheme is 360 million kilowatts (about 30% of China's total installed power capacity), the middle scheme is 240 million kilowatts (about 20% of China's total installed power capacity), and the low scheme is 120 million kilowatts (about 10% of China's total installed power capacity).
3. The National Development and Reform Commission of China is preparing a plan for the development of China's nuclear power for civil industry. It is expected that China's total installed power capacity will be 900 million kilowatt hours by 2020, and nuclear power will account for 4% of the total power capacity, that is, China's nuclear power will be 36 million to 40 million kilowatts by 2020.That is to say, by 2020, China will have 40 buildings equivalent toDaya BayA million kilowatt nuclear power plant like that.
4. From the general trend of nuclear power development, the technical and strategic lines of China's nuclear power development have long been clear and are being implemented. At present, pressurized water reactors are being developed, fast reactors are being developed in the medium term, and fusion reactors are being developed in the long term.Specifically, recent developmentThermal reactornuclear power plant;In order to make full use of uranium resources, adopt the technical route of uranium plutonium cycle, and develop in the medium termFast breeder reactornuclear power plant;Develop fusion reactor nuclear power plants in the long term, so as to basically solve the contradiction of energy demand "forever".

On April 20, 2022, Premier Li Keqiang presided over the executive meeting of the State Council, which made it clear that nuclear power should be developed in an orderly manner under the premise of strict supervision and ensuring absolute safety, and that three new nuclear power unit projects in Sanmen, Zhejiang, Shandong Haiyang and Lufeng, Guangdong, which had been included in the national plan after years of preparation and comprehensive assessment and review, should be approved.There are six newly approved nuclear power units in total, and each project has two units. The four nuclear power units approved in Sanmen Nuclear Power Phase II and Haiyang Nuclear Power Phase II adopt the localization CAP1000 technology, and the two nuclear power units of Lufeng Nuclear Power No. 5 and No. 6 adopt the Hualong No. 1 technology.[3]
In 2022, at the National Energy Work Conference, the National Energy Administration proposed to orderly promote the approval and construction of nuclear power projects with reliable conditions on the premise of ensuring safety. In 2022, it is planned to build four units of the Fuqing 6, Hongyanhe 6, Fangchenggang 3 and high-temperature gas cooled reactor demonstration project, with an additional installed capacity of 3.67 million kilowatts.[3]
In 2023, China will approve five new nuclear power projects and start five new nuclear power units.
By the end of 2023, China's mainland has 55 nuclear power units in operation, with a total installed capacity of 57 GW, and 36 nuclear power units approved and under construction, with a total installed capacity of 44 GW;The annual nuclear power generation capacity was 440000 GWh, accounting for nearly 5% of the total national power generation.[6]
As of April 2024, China has 26 nuclear power units under construction, with a total installed capacity of 30.3 million kilowatts, continuing to rank first in the world.[5]

Sanmen Nuclear Power, Haiyang Nuclear Power and Lufeng Nuclear Power are affiliated to three major nuclear power companies in China: China National Nuclear Corporation, State Power Investment Corporation and China Guangdong Nuclear Power.
Both Sanmen Nuclear Power Project and Haiyang Nuclear Power Project are planned to build six nuclear power units in three phases.Two AP1000 megawatt pressurized water reactor nuclear power projects will be constructed in the first phase of the project as the supporting projects for nuclear power localization.
Six nuclear power units are planned to be built in Lufeng Nuclear Power Project. The first phase of Lufeng Nuclear Power Project was originally planned to use the AP1000 technology, while the newly approved units 5 and 6 have turned to the Hualong 1 technology.[3]
