China's nuclear power ranks first in the world

Recently, the good news came from Fuqing, Fujian Province, that the second unit of China's independent third-generation nuclear power Hualong No. 1 demonstration project - CNNC Fuqing No. 6 nuclear power unit officially has the conditions for commercial transport, so far, Hualong No. 1 demonstration project has been fully completed and put into operation.

When the news broke, the world watched. As the "national business card" of China's nuclear power to the world, Hualong One is one of the three generations of nuclear power models with the highest acceptance in the current nuclear power market, and its full completion is a major achievement in China's nuclear power development in the new era, marking that China's nuclear power technology level and comprehensive strength rank first in the world, and strongly support China's leap from a nuclear power to a nuclear power.

Third generation nuclear power optimization scheme

"Hualong One is one of the three generation nuclear power models with the highest acceptance in the current nuclear power market. It is a third generation pressurized water reactor nuclear power innovation achievement with completely independent intellectual property rights developed and designed by CNNC on the basis of more than 30 years of nuclear power research, design, construction, operation and management experience. It meets the highest international safety standards and is fully equipped with mass construction capabilities. It has become China's third-generation nuclear power plan for contributing to the world." China National Nuclear Group relevant responsible person introduced.

What is a third-generation nuclear power plant? How are the generations of nuclear power plants divided? Since 1954, when the former Soviet Union built an experimental nuclear power plant with an electric power of 5 megawatts, the development of nuclear power technology can be divided into four generations.

The first generation of nuclear power plants refers to the experimental prototype nuclear power plants developed and constructed by various countries in the 1950s, which proved that the technology of using nuclear energy to generate electricity is feasible. The second generation refers to the majority of commercial nuclear power plants in operation from the 1970s to the present, proving that the development of nuclear power is economically viable. The third generation nuclear power plant refers to a new generation of advanced nuclear power plant technology that meets the requirements of the United States User Document (URD) or the European User Requirement Document (EUR) and has higher safety. Fourth generation nuclear power is a nuclear power plant with major innovations in the reactor and fuel cycle, which looks at the longer term development of nuclear energy, but will not be commercially available until after 2030 at the earliest.

According to Xing Ji, chief designer of China National Nuclear Group "Hualong One", Hualong One in the use of engineering proven mature technology based on the original use of "177 core arrangement" and "active and passive combination of" safety design concept, the first pile equipment localization rate of 88%, but also the use of single pile arrangement, double containment and other advanced design concepts. It has advanced features such as perfect serious accident prevention and mitigation measures, enhanced external event protection capability and improved emergency response capability, and has been fully analyzed, tested and verified by engineering, fully ensuring the safety, economy and advanced nature of the power plant.

Yu Jianfeng, secretary of the Party Group and chairman of the China National Nuclear Group, said that from Qinshan to Fuqing, China's nuclear power from the technical "poor white" start, to the independent design and construction of million-kilowatt nuclear power plants, China has become one of the few countries in the world with a complete nuclear industry system, and on this basis formed a complete nuclear power industry chain, to achieve the large-scale development of nuclear power.

The role of industry is significant

Where does Hualong One get the confidence to "go out"? Hualong One has complete independent intellectual property rights. In collaboration with 17 universities and research institutions in China, 58 state-owned enterprises and more than 140 private enterprises, CNPC jointly broke through the localization of 411 sets of equipment including core equipment such as reactor pressure vessels, steam generators and reactor internals, and obtained a total of more than 700 patents and more than 120 software Copyrights. It covers design technology, special design software, fuel technology, operation and maintenance technology and other fields to meet the requirements of nuclear power "going out".

"At present, the Hualong One has entered the mass construction stage, with projects under construction at home and abroad, and nearly 20 countries have expressed their intention to adopt the technology." Xing Ji introduced.
