Nuclear power plant successfully connected to the network, the arrival of a nuclear era

At 14:58 on the 28th, as Unit 1 of the Ningde Nuclear Power Station was successfully connected to the grid, Fujian Power Grid entered the “nuclear age” from this point. The zero breakthrough in nuclear power will have a profound impact on the economic and social development of our province

Increased proportion of clean energy

"Nuclear power is a safe, clean and economical power source. The commissioning of Unit 1 at the Ningde Nuclear Power Station will increase the proportion of clean energy in our province, will help save energy and reduce emissions, reduce resource consumption, and build a beautiful Fujian." Provincial Development and Reform Commission is responsible for People said.

At present, the province's hydropower, wind power, LNG and other clean energy accounts for a relatively high proportion of the country. The “12th Five-Year Plan” energy development plan of Fujian Province proposes that by 2015, the proportion of clean energy installed capacity in the province will increase from 45.4% in 2010 to 47.8%. With the completion of the basic hydropower development in the province, nuclear power projects will be completed and put into operation one after another and will play a crucial role in fulfilling the provincial clean energy planning goals.

According to plan, Ningde Nuclear Power and Fuqing Nuclear Power will each put into production one unit by the end of next year or early next year. With the successive launch of 7 nuclear power units in Ningde and Fuqing, the proportion of clean energy in Fujian will reach 52%.

Nuclear power plants do not generate carbon dioxide, dioxide*, nitrogen oxides, and soot. Taking a nuclear power plant with a capacity of 1 million kilowatts and a coal power station as an example, the annual power generation capacity of Unit 1 of Ningde Nuclear Power Plant can reduce CO2 emissions by 6 million to 6.5 million tons, and CO2 emissions from 17,000 to 44,000 tons by nitrogen. Oxides 15,000 to 22,000 tons, and other dust 320,000 to 1.5 million tons. Therefore, the completion and production of Ningde Nuclear Power Unit 1 will significantly reduce environmental pollution and improve atmospheric environmental capacity.

The Ningde Nuclear Power Unit 1 requires about 30 tons of fuel per year, which is equivalent to the load of a heavy truck; the equivalent capacity of coal-fired power plants requires 3 million tons of coal, equivalent to 50,000 standard train loads. Due to the lack of energy resources in Fujian, the lack of coal and oil, and the completion of nuclear power production, it can not only reduce resource consumption, but also ease the pressure on railroads and highways caused by large amounts of coal transportation.

Power supply structure optimization power supply is more secure

At present, there are 38.77 million kilowatts of power installed in the province, 11.38 million kilowatts of hydropower, 26.26 million kilowatts of thermal power, and 1.13 million kilowatts of new energy such as wind power. After the Ningde and Fuqing nuclear power plant units are all put into production, the power supply structure of the Fujian power grid will shift from thermal power and hydropower to the deployment of thermal power, hydropower, and nuclear power simultaneously.

“The completion and production of Unit 1 of Ningde Nuclear Power Station has enabled the diversified development of the power structure in Fujian, and will further ensure the safe and stable operation of the power grid.” Huang Wenying, Deputy Chief Engineer of the State Grid Fujian Electric Power Co., Ltd. and Director of the Provincial Power Control Center, said that Ningde The daily power generation capacity of Unit 1 of the nuclear power plant reached 24 million kwh, which exactly meets the increasing demand for electricity load in the province next year. Therefore, the power supply in our province will be relatively abundant next year.

It is reported that Ningde Nuclear Power will access the Fujian power grid through four 500 kV lines, two 500 kV Ningde substations, and two 500 kV Puili substations. At present, the 500 kV Ningde Nuclear Power Plant—Ningde Substation I and II transmission line project has been put into production. The 500 kV Ningde NPP-Yuli Substation I and II line transmission line project will also be put into operation by the second nuclear power unit in 2013. Completely built during shipment, to meet the needs of nuclear power delivery.

In order to ensure the safety of Ningde nuclear power transmission, the provincial power company adopted a series of safety and security measures, carried out several safety inspections involving the network, put forward some strengthening measures, and did a good job of various emergency plans drilling.

In order to make full use of hydropower, wind power, and nuclear power resources to ease the peak load adjustment of the Fujian power grid and ensure the safe and stable operation and delivery of nuclear power plants, the State Grid Corporation of China is accelerating the UHV networking project between Fujian and East China. In conjunction with the commissioning of the second unit of Ningde Nuclear Power in 2013, the provincial power company will build a 500 kV second channel along the coast to meet the demand for Ningde nuclear power transmission to southern Fujian.
