High-quality development research into Shenzhen Daya Bay Nuclear Power: Nuclear power localization rate increased to 90%

　　When it comes to the development of nuclear power in China, the Daya Bay Nuclear Power Station must be one of the key words that cannot be avoided
.
The Daya Bay Nuclear Power Plant located in Shenzhen has grown together with the special zone.
It is the first large-scale commercial nuclear power plant in mainland China and a landmark project of reform and opening up.
It shoulders the historical mission of starting from a high starting point for China's nuclear power
.

　　After years of development, a relatively complete and powerful nuclear power development industry chain has been created in China, nuclear power has become a "national business card", and China has become one of the world's largest nuclear power countries
.
Daya Bay Nuclear Power not only contributes surging power to the Guangdong-Hong Kong-Macao Greater Bay Area, but also contributes to the cultivation of national nuclear power talents and technological exploration
.

　　A few days ago, the research team of the "High-Quality Development Research Tour" organized by the Propaganda Department of the Shenzhen Municipal Party Committee came to Shenzhen Daya Bay Nuclear Power Station and the Comprehensive Thermal, Hydraulic and Safety Laboratory of China General Nuclear Power Research Institute to discuss the exploration and development of China General Nuclear Power and Daya Bay Nuclear Power in the field of nuclear power.

　　Nuclear power localization rate increased from 1% to 90%

　　In August 1980, the Shenzhen Special Economic Zone was formally established, and in October of the same year, the leading group for the preparation of nuclear power plants in Guangdong Province was formally established
.
It can be said that Daya Bay Nuclear Power and Shenzhen Special Economic Zone have grown together, shouldering the historical mission of starting from a high starting point for China's nuclear power
.

　　As the largest Sino-foreign joint venture project in the early stage of reform and opening up, the Daya Bay Nuclear Power Station was constructed in accordance with the principles of "introduction, digestion, absorption, and re-innovation" and "borrowing and construction, repayment from electricity sales, and joint venture operation".
It was officially approved by the state in 1982.
The main project Construction started on August 7, 1987, and it was fully completed on May 6, 1994
.

　　After years of development, the Daya Bay Nuclear Power Base now has a total of six million-kilowatt nuclear power units including Daya Bay Nuclear Power Station and Ling'ao Nuclear Power Station (Phase I and Phase II)
.
Since the introduction of the M310 technology route in the Daya Bay Nuclear Power Station, CGNPC has begun to explore the localization of nuclear power technology
.
It has successively developed CPR1000 and its upgraded version CPR1000+, a nuclear power technology route with its own brand of one million kilowatts, and ACPR1000, a nuclear power technology route that meets the third-generation standards, and finally developed its own brand, the third-generation nuclear power technology Hualong No.

　　According to the data, from Daya Bay Nuclear Power Station localization rate of less than 1%, to Ling'ao Nuclear Power Station Phase I 30%, Ling'ao Phase II Phase 64%, and then to Hualong No.
1 close to 90%, China's nuclear power localization rate has increased significantly.
A relatively complete and powerful nuclear power development industry chain has been created in China, nuclear power has become a "national business card", and China has become one of the world's largest nuclear power countries
.

　　Safe operation for 28 years, accumulative on-grid electricity is 868.
6 billion kWh

　　Safety is the lifeblood of nuclear power development
.
Since the first unit of Daya Bay Nuclear Power Plant was put into commercial operation in 1994, it has maintained safe and stable operation, and its safety operation performance is better than the international advanced level
.

　　According to reports, in 2021, among the 72 WANO (World Association of Nuclear Power Operators) indicators for the six units of the Daya Bay Nuclear Power Base, 60 will reach the advanced level of the top quarter in the world, accounting for 83.
3%; 58 of them will reach the world's top ten 1/1 of the excellent level, the excellent rate reached 80.
6%
.

　　It is particularly worth mentioning that as of now, Ling'ao Phase I Unit 1 has operated continuously for more than 5,700 days, and it is still breaking the international record of safe operation days for similar units, nearly 60 days ahead of the second-ranked French unit.

.

　　As of June 30, 2022, the six units of the Daya Bay Nuclear Power Base had accumulated on-grid electricity of 868.
6 billion kWh, of which the cumulative power supply to Hong Kong reached 292.
4 billion kWh, accounting for a quarter of Hong Kong's total electricity consumption
.
Clean, efficient and reliable nuclear power has played an active role in meeting the power supply in the Guangdong-Hong Kong-Macao Greater Bay Area and improving the energy structure
.

　　The "Whampoa Military Academy" for nuclear power talent training has exported tens of thousands of talents

　　Nuclear power development, talent first
.
During the more than 40 years of growing together with the Shenzhen Special Economic Zone, Daya Bay Nuclear Power Base has established a complete talent training system and training facilities, and is known as the Huangpu Military Academy for talent training of CGN and China Nuclear Power
.

　　According to reports, the training system of Daya Bay Nuclear Power Base can carry out all-round training from main control room operators to refueling operators, maintenance technicians, to engineering construction talents and management talents
.
According to the staff, a new employee who has graduated from a university needs 4-5 years of unremitting efforts to pass hundreds of trainings and exams, as well as layers of written exams, simulator exams and oral exams organized by the National Nuclear Safety Administration.
The test, and finally become a qualified main control room operator, its difficulty is no less than training a pilot
.

　　In the large-scale development of China's nuclear power, Daya Bay Nuclear Power has "exported" a large number of talents to the outside world, bringing much-needed management and technical experience to new power plants
.
At the same time, Daya Bay Nuclear Power also carried out "management output" to standardize management and technology, and the experience can be replicated and applied in each new nuclear power base to help improve the operation level
.

　　Data shows that Daya Bay Nuclear Power currently has a cumulative output of tens of thousands of talents, which are located in major nuclear power plants in China.
There are not only professional and technical personnel, but also a large number of management personnel.
Therefore, Daya Bay Nuclear Power Base is also known as the "Huangpu Military Academy" for nuclear power talent training
.

　　Environmental benefits equivalent to planting nearly 1.
95 million hectares of forest

　　In terms of environmental monitoring, Daya Bay Nuclear Power continued to conduct real-time monitoring and sampling monitoring of the base and surrounding environment, water quality and biodiversity
