China News Service, Beijing, September 12 (Zhang Wenhui) On the 11th, the "Hualong One Road to Independent Innovation" media tour was launched in Beijing, focusing on promoting the independent innovation results and technological advantages of Hualong One 2.0 version. According to reports, Hualong One version 2.0 adopts Chinese standards and has the capability of 100% localization of key equipment. Its safety performance indicators are in the first echelon among the world's large pressurized water reactors.
Hualong One is a million-kilowatt third-generation pressurized water reactor nuclear power technology with completely independent intellectual property rights developed by China National Nuclear Corporation and China General Nuclear Power Group based on more than 40 years of experience in nuclear power research and development, design, manufacturing, construction and operation in China. It is known as the "national business card".
Hualong One version 2.0 is a "third generation plus" advanced pressurized water reactor nuclear power technology launched through independent innovation and overall collaboration based on feedback from the construction and operation of Hualong One. It is a major landmark achievement in my country's nuclear power from "generally parallel running" to "comprehensive parallel running and partial leadership".
The development of nuclear power plays a very important role in promoting my country's independent innovation capabilities, comprehensive scientific and technological strength, and creating a source of original technology. According to reports, Hualong One version 2.0 adopts Chinese standards, autonomous software and optimized active and passive safety systems, and uses advanced technologies in intelligent control, modular construction and other aspects to significantly reduce the project volume, improve safety, advancement and economy in all aspects, and have stronger comprehensive competitiveness.
In terms of advancement, Hualong One version 2.0 adopts advanced core protection technology, advanced core control technology, advanced instrumentation and control technology, intelligent nuclear power technology and other technologies. It also has passive starting capabilities, which improves the operating flexibility and convenience of operation and maintenance of the unit, and reduces the workload of construction personnel and operation and maintenance personnel.
In terms of safety, Hualong One 2.0 adopts optimized active and passive safety technologies and comprehensively optimizes 14 safety features on the basis of the original defense-in-depth safety system. Nine of the key safety indicators have been significantly improved. It can achieve 72 hours of non-intervention by the operator and 7 days of accident autonomy after an accident. Its safety performance indicators are already in the first echelon among the world's large pressurized water reactors.
In terms of economy, while further improving overall safety, Hualong One 2.0 has comprehensively simplified the configuration of auxiliary systems, significantly reduced the number of equipment and the use of bulk materials, thereby reducing the amount of engineering and construction costs; further optimizing the layout of plant equipment, adopting modular advanced construction technology on a large scale, significantly reducing on-site workload, shortening the construction period, and reducing construction risks. Various optimization measures have greatly enhanced the commercial competitiveness of the unit.
At the same time, while having the ability to 100% localize key equipment, it has driven nearly 6,000 upstream and downstream companies to form a complete industrial chain supply system, which is highly coordinated with China's equipment industry chain and construction industry chain, effectively leading the upgrading of China's manufacturing industry, and significantly improving its global comprehensive competitiveness.
Up to now, Hualong One has 11 units in commercial operation at home and abroad, and another 36 units have been approved for construction. The total number of units ranks first among the world's third-generation nuclear power. Its maturity has been verified by large-scale and batch construction and operation. It has become the main brand of my country's independent third-generation nuclear power, contributing actively to the realization of the "double carbon" goal.
Nuclear power is not only a provider of clean energy, but also a guardian of ecological protection. It is understood that the annual designed power generation of a single unit of Hualong One is nearly 10 billion kilowatt-hours, which can meet the annual production and living electricity needs of a medium-sized city with a population of over one million, which is equivalent to reducing the consumption of standard coal by more than 3 million tons and reducing carbon dioxide emissions by more than 9 million tons per year.
As more Hualong 1 units are completed and put into operation, it will further enhance the resilience and independence of my country's energy supply, better serve the construction of new energy systems, ensure national energy security, and provide a smarter "Chinese solution" for the green and low-carbon transformation of global energy.
It is understood that this media tour was co-sponsored by the "Green Nuclear Energy" nuclear power science popularization cooperation platform in conjunction with China National Nuclear Corporation, China Huaneng, China General Nuclear Power Group, and Shanghai Electric. It is one of the highlights of the annual themed science popularization campaign of "Hualong One's Road to Independent Innovation."
