On the morning of June 28, 2021, the first batch of hydroelectric generating units of China's Baihetan Hydropower Station were officially put into operation to generate electricity, many friends know that the single scale of the hydroelectric generator set here is the largest in the world, and the stator base of its generator set is 20 meters in diameter, comparable to the length of two ordinary buses, and the height of the erection is even more amazing, more than 50 meters high, equivalent to the height of a 17-story building, and the total weight is as high as more than 8,000 tons, which is equivalent to the launch weight of 10 Long March 5, or the weight of a heavy destroyer.
Of course, the power generation capacity of such a huge hydroelectric generator is also quite strong, and its power generation power is as high as 1 million kilowatts, which is the largest single unit capacity in the world among hydroelectric generators in the world.
However, at 22:35 p.m. on January 1, 2022, unit 6 of the Fuqing Nuclear Power Plant located in Sanshan Town, Fuqing City, Fuzhou, Fujian Province, China was successfully connected to the grid, which is the second "Hualong No. 1" nuclear energy generator set connected to the grid in China, with a power generation capacity of up to 1.161 million kilowatts, which is 161,000 kilowatts higher than the power of the hydroelectric generator unit of the Baihetan Hydropower Station, 16.1% higher, is it more cattle!
Or for reasons of technical confidentiality, there is no relevant data on the scale of Hualong No. 1 nuclear power unit on the network, but from the power generation power, it can be imagined that the scale of its generating unit should be no less than that of the hydro-generator set of Baihetan Hydropower Station.
Hualong No. 1 nuclear power unit has been built three, CNNC Fuqing Nuclear Power Plant Units 5 and 6 are the use of Hualong No. 1 technology, of which Unit 5 has been connected to the grid on January 30, 2021, it is the world's first grid-connected Hualong No. 1 generator set; the second is in Karachi, Pakistan, has been connected to the grid on March 18, 2021; so Fuqing Nuclear Power Plant Unit 6 is also China's second unit, the world's third Hualong No. 1 nuclear energy generating unit. After the grid-connected power generation is confirmed on the spot, the technical indicators of the unit meet the design requirements and the operation state is good, laying a solid foundation for the subsequent formal commercial operation.
The fourth unit of Hualong-1 in the world is Unit 3 of the Karachi Nuclear Power Project in Pakistan, which has completed nuclear fuel loading on December 31, 2021, and is expected to be connected to the grid in mid-2022.
The picture above and below shows the Hualong-1 reactor at the Karachi Nuclear Power Plant in Pakistan.
Hualong No. 1 nuclear power unit with powerful power generation function, the annual power generation capacity can reach tens of billions of degrees (kWh), can meet the industrial production and residential electricity demand of a medium-sized city with a million population level, need to consume about 30 tons of uranium, compared to the coal-fired power station can reduce the burning of standard coal 3.12 million tons per year, reduce carbon dioxide emissions by 8.16 million tons, to reduce the emission of so much carbon dioxide needs more than 70 million trees, so Hualong No. 1 as the representative of Henan power generation to optimize China's energy structure, Achieving green and low-carbon development, achieving carbon emission reduction and carbon neutrality goals all play an important role.
"Hualong No. 1" nuclear energy generator set not only has a strong power generation power, the safety factor is also very high, it is China's nuclear energy field workers seriously summarize the world's decades of nuclear power research and design and operation experience, set a number of long design and construction of the third generation of nuclear power generation facilities, its design comprehensively and balanced implementation of the nuclear safety defense principle and design reliability principle, the unit set up a multi-channel safety barrier, can ensure that the unit in operation are placed under the protection of defensive measures, the casing also adopts a collision-proof and anti-seismic design, the use of double-layer containment It can withstand both the impact of large aircraft and the earthquake of large magnitude, and is the most safe and reliable nuclear energy generating unit in the third generation of nuclear power technology.
