China's independent third-generation nuclear power
"National Business Card" Hualong No. 1
Mass construction has been reported frequently
December 27, 28dayThe inner dome of Unit 4 of CNNC Hainan Changjiang Nuclear Power Base and the outer dome of Unit 2 of Zhangzhou Nuclear Power Plant have been successfully hoisted, laying a solid foundation for the installation and commissioning of subsequent units and grid-connected power generation.

Zhangzhou Nuclear Power Unit 2.
Hualong 1 is a double-layer containment vessel with a dome located at the top of the nuclear island, whose main function is to ensure the integrity and tightness of the reactor plant, and plays a key role in radioactive containment. In order to promote the dome hoisting work with high quality, the participating units of the two major sites of CNNC in Zhangzhou, Fujian Province and Changjiang, Hainan Province attach great importance to and work together, and successively organize special inspections on construction prerequisites, safety and quality to ensure that the quality and safety of the hoisting work are controlled. On the day of hoisting, after a series of high-precision actions such as hooking, lifting, luffing, counterclockwise rotation of the boom, and walking with load, the dome was finally successfully hoisted in place.
Hualong No. 1 is not only an important achievement of CNNC to accelerate the realization of high-level scientific and technological self-reliance and self-reliance and the implementation of the national "dual carbon" strategy, but also one of the most competitive third-generation nuclear power models in the current nuclear power market.
1. The "national business card" of China's nuclear power to the world has become the preferred plan for China's third-generation nuclear power to contribute to the world, which plays a positive role in ensuring China's energy security and optimizing the energy structure.
After the completion of the first phase of Zhangzhou nuclear power project, the two units are expected to generate more than 20 billion kilowatt hours per year, which is equivalent to saving about 6 million tons of coal and reducing carbon dioxide emissions by 16.32 million tons per year, which is equivalent to afforestation400 million.
As one of the important bases of China's nuclear power industry, Hainan Changjiang Nuclear Power Base has maintained safe and stable operation for a long time, and the projects under construction have formed a pattern of "double dragons flying together, three reactors jointly built". On February 21, the inner dome of Unit 3 was successfully hoisted, and on November 3, the top head of the "Linglong No. 1" small reactor was successfully hoisted, and with the successful hoisting of the inner dome of Unit 4, Hainan Changjiang Nuclear Power Base became the first nuclear power base in China to complete the hoisting of three domes in the same year.
