Daya Bay Nuclear Power Station

Dayawan nuclear power station is located in Shenzhen, Guangdong, China. It is the second nuclear power plant built in mainland China, and the first Chinese mainland to use foreign technology and capital to build nuclear power stations. Since then, Ling'ao nuclear power station has been built on the side of Daya Bay nuclear power station, which together form a large nuclear power base. Initially, the Daya Bay nuclear power station was built to supply power to Hong Kong. In the early 1980s, it was named Daya Bay nuclear power station because it was located in Ling'ao village on the Bank of Daya Bay. The power station was introduced to Hong Kong's power suppliers for equity participation, and most of the electricity generated was sold to Hong Kong. In order to eliminate the concerns of all parties, the nuclear island technology and equipment from France and conventional island technology and equipment from Britain were introduced for construction and management, and the quality assurance was provided by an American company. After all kinds of ups and downs, Daya Bay nuclear power station was finally started in 1987. Using pressurized water reactor technology, two 900000 kW generating units were installed, and all of them were connected to the grid in 1994. After the completion of the Daya Bay nuclear power station, the Chinese government decided to continue to build a new nuclear power station, named Ling'ao nuclear power station, 1000 meters west of the Daya Bay nuclear power station. Lingao nuclear power station is planned to install four 1 million generating units, which will be constructed in two phases. The first phase of the project started in 1997 and installed two pressurized water reactor generating units. Technically, the modification of Daya Bay nuclear power station was adopted and the localization rate of equipment was increased. The project was put into operation in 2002. The second phase of the project is also two pressurized water reactor generating units, which will be built between the first phase of the project and Daya Bay nuclear power station. Guangdong Province, where Daya Bay Ling'ao nuclear power station is located, has a pumped storage power station, namely Guangzhou Pumped Storage Power Station, which can provide supporting facilities for the safe, stable and economic operation of nuclear power station. It is located in Conghua City, Guangdong Province, with eight 300000 kW generating units installed, with a total installed capacity of 2.4 million KW

Historical evolution

On December 4, 1978, Deng Xiaoping met with French Foreign Trade Minister Francois Francois and his party, and publicly announced that China had decided to purchase two nuclear power plant equipment from France when answering questions from French journalists.

Around 1980, the power supply in Hong Kong was once tight. In order to seize this opportunity, the Ministry of water resources and power of the people's Republic of China and the Guangdong provincial government planned to build a nuclear power station in Dapeng Town, Shenzhen, which is close to the power load centers of Hong Kong, Guangzhou and Shenzhen. Because the site is near the Daya Bay, it is named Daya Bay nuclear power station. The power station is a joint venture between the mainland and Hong Kong China Power Company (25% of Hong Kong's shares), and most of the generated power is sold to Hong Kong. However, during the preparatory period, the Chinese government and the British government discussed the final ownership of Hong Kong and other events, which delayed the construction of the nuclear power plant.

On December 13, 1982, the fourth executive meeting of the State Council discussed the construction of nuclear power station in Guangdong Province, and the meeting decided to build Daya Bay nuclear power station. Later, the nuclear island technology and equipment from France and conventional island technology and equipment from Britain were introduced for construction and management, and the quality assurance was provided by an American company.

On August 7, 1987, the project was officially started. Using pressurized water reactor technology, two 980000 kW generating units were installed, and all of them were connected to the grid in 1994.

Daya Bay nuclear power station is the first large-scale commercial nuclear power station in China to introduce advanced technology, equipment and capital. It has two PWR nuclear power units with a single unit capacity of 984000 kW, which are jointly constructed and operated by Guangdong Nuclear Power Group of China and China Power Corporation of Hong Kong. The construction of the nuclear power plant started in August 1987 and was completed and put into commercial operation in May 1994.

According to the joint venture contract, the joint venture period of Daya Bay nuclear power plant is 20 years, from 1994 to 2014. During the joint venture period, 70% of the electricity of Daya Bay nuclear power station will be transmitted to Hong Kong. As of August 31, 2012, Daya Bay nuclear power station has achieved a total of 2012 billion kwh of on grid power, 144.3 billion kwh of power transmitted to Hong Kong, accounting for one fourth of Hong Kong's total electricity consumption. According to the contract for extending the joint venture period signed this time, after the first joint venture period of Daya Bay nuclear power plant ends in 2014, both parties will extend the joint venture period for another 20 years to 2034.

On April 6, 2016, at the award ceremony of 2015 international safety performance challenge for similar units held in Paris, Daya Bay Nuclear Power Operation Management Co., Ltd., affiliated to China Guanghe group, won the first place in "capability factor" and "nuclear safety / automatic shutdown". So far, Daya Bay operation company has won the first place in 34 times.

Brief introduction of power station

Daya Bay nuclear power base, located in Dapeng New District, Shenzhen City, Guangdong Province, has two nuclear power stations, Daya Bay nuclear power station and Ling'ao nuclear power station, with a total of six million kilowatt class PWR nuclear power units, with an annual power generation capacity of about 45 billion kwh. Among them, 80% of the electricity generated by the Daya Bay nuclear power station goes to Hong Kong, accounting for about a quarter of the total social electricity consumption in Hong Kong, and 20% goes to China Southern Power Grid;

All the power generated by Ling'ao nuclear power station is transmitted to China Southern Power Grid. According to the statistics in 2011, the power transmitted by the two nuclear power plants to China Southern Power Grid accounts for about 9% of the total social electricity consumption in Guangdong Province. Daya Bay nuclear power base is the first large-scale commercial nuclear power station in China, covering a total area of about 10 square kilometers, including Daya Bay nuclear power station, Ling'ao Nuclear Power Station Phase I and Ling'ao Nuclear Power Station Phase II. Looking down from the viewing platform of Ling'ao Nuclear Power Plant Phase I, the nuclear power plant and the blue sky and sea set off each other, forming a magnificent picture.

The silver gray public relations center exhibition hall is the first classroom to understand the nuclear power station. There are panoramic sand table models, nuclear island, conventional island and related equipment models of Daya Bay nuclear power station, as well as many popular science pictures, texts, simulators, question answering machines and other exhibits, from which you can understand the overall picture of Daya Bay nuclear power station, the principle of nuclear power generation, and the safety and reliability of pressurized water reactor nuclear power station And nuclear power plant construction.

From the exhibition hall, you can stroll along the coastal avenue of Daya Bay base and go to the material wharf to see the sea. The material wharf has a romantic name -- lover island. It used to be the material handling Wharf in the early stage of the construction of Daya Bay nuclear power station. It is close to the mountains and the sea, and has beautiful scenery. Now it has become a garden style seascape wharf for people to fish and watch the sea.

Daya Bay nuclear power station started construction in accordance with the principle of "starting from a high starting point, introducing, digesting, absorbing and innovating", "borrowing construction, selling electricity to repay money and joint venture". It was fully completed and put into commercial operation on May 6, 1994. And won the "1994 power plant Award" by the international power magazine published in the United States, becoming one of the five award-winning power plants in the world, and the only nuclear power plant in China to win this award. In May 1995, the Daya Bay nuclear power station was designated as the "patriotic education base of Shenzhen" by the Shenzhen Municipal Committee of the Communist Party of China, and became one of the scenic spots for one-day tour in Shenzhen.

Since the Daya Bay nuclear power plant was put into operation, the economic operation indexes have reached the international advanced level. Since 1999, it has won the first place in 25 safety performance challenges in five fields with 64 French units of the same type. 13 May 2006
