Sun Qin: Independent Innovation Creates China's Nuclear Power Brand

"In the field of peaceful nuclear energy use, if you do not seize the commanding heights, it is very easy for people to get stuck." According to Sun Qin, general manager of CNNC, the soul of the Chinese nuclear industry is independent innovation, and the most critical task of China's current nuclear power is It is necessary to establish a China nuclear power brand with independent intellectual property rights based on independent innovation and exchange with advanced nuclear power technology abroad.

According to Sun Qin, CNNC inherited and carried forward the fine tradition of independent innovation in the nuclear industry. In recent years, it has achieved numerous technological innovation achievements. Particularly in the field of nuclear power, CNNC actively implemented the three-step strategy of “heat reactor-rapid reactor-fusion reactor” for nuclear power development, and achieved the scientific development model of “manufacturing generation, development generation, pre-research generation, and reserve generation” of nuclear power technology. A nuclear power development path that is not subject to foreign countries, is based on me, and maintains the advanced level of the world.

It is also due to the unremittingly independent innovation that China’s nuclear power has begun to show signs of accelerating momentum, and has ran out of China’s speed in its own branded third-generation nuclear power generation, fourth-generation advanced nuclear power system technology, small reactors, and nuclear fuel security.

It is understood that in the development of China’s nuclear power industry, China National Nuclear Corporation was the first person to go abroad. It independently designed and built Pakistan’s Chashma Nuclear Power Station No. 1 and No. 2 and achieved safe and stable operation. International experience in contract management of large-scale nuclear power projects.

"Nuclear power export must have complete independent intellectual property rights, so it has become an important measure of whether a country is a truly nuclear power, and nuclear power exports are independent and must have complete independent intellectual property rights. The United States, France, Russia, and South Korea have all achieved The nuclear power went out of the country," Sun Qin said. "The reason why China's nuclear power does not go out is that it does not have independent intellectual property rights. Therefore, we must independently innovate."

According to the information, as the owner of the world's first AP1000 nuclear power unit, CNNC is currently accelerating the introduction, digestion, and absorption of third-generation nuclear power technologies, and on this basis, it will integrate and integrate its own prototype reactors, large-scale commercial reactors with independent intellectual property rights, and Canada. The heavy water reactors and VVER reactors in Russia have rich experience in construction, operation and management. Through innovation, they have developed ACP series third-generation nuclear power technologies with independent intellectual property rights and higher safety, and some have been transferred to the overall design stage of the project.

Rapid reactor industry system has been formed At the same time, China's fourth generation of advanced nuclear power - fast reactor R & D schedule is also increasingly clear.

It is understood that the China Experimental Fast Reactor has been built from scratch. From design and construction to successful grid-connected power generation, it has experienced a process that focuses on me, independent innovation, and joint research.

According to information provided by the China Atomic Energy Research Institute, through the implementation of the China Experimental Fast Reactor project, China has already mastered most of the core technologies of the fast reactor. A set of fast reactor standard specification system was established and a software library for the design and safety evaluation of sodium cooled fast reactors was developed. The rapid physics, thermal engineering, mechanics, safety, materials, fuels, and equipment were developed. Dozens of experimental devices were studied.

In addition, through joint research with a number of companies across the country, the localization rate of experimental fast reactor equipment has reached 70%, including heap containers and cocks, nuclear grade sodium, automatic refueling control systems, transfer machines, reflector components, and shielding components. Fast reactor nuclear testing, control and protection systems. These results indicate that China has already formed a basic supporting fast reactor industry system.

It is understood that the experimental fast reactor currently built will further verify its performance, carry out research on safe operation technology, and accumulate experience in the operation of sodium-cooled fast reactors. At the same time, as China’s first fast neutron irradiation device, it irradiates test fuels and materials, breaks through fuel and material technology, and also serves as a working condition environment for sodium-cooled fast reactors, tests domestically produced equipment, and accumulates experience for the development of commercial fast reactor power plants. .

Small piles, large piles complement each other In the ACP series of independent intellectual property rights, ACP100 is also the focus of the next step in the development of China National Nuclear Corporation.

“Small heap development is an international hotspot and there is an urgent need in the country. Compared with the third generation of technology, it can be made more elaborate in terms of security. Small piles will complement each other.” Sun Qin introduced.

It is understood that China National Nuclear Corporation is developing a 2×100MW advanced small-scale pressurized water reactor, which is based on China's more than 10 years of small reactor technology research achievements. It is expected to be successfully developed in the near future, with demonstration and deployment conditions.

Relevant information shows that the small reactor can meet the needs of applications in special fields such as power supply for small and medium-sized power grids (with a total installed capacity of less than 4 million kilowatts), urban heating, industrial process heating, and seawater desalination, and has broad application prospects. According to the latest statistics from the IAEA, there are currently 132 small and medium-sized reactors in operation worldwide, of which 106 are medium-sized reactors, 26 are small-scale reactors, and 13 are under construction. There are 28 small and medium-sized reactors in the country. The total capacity of all these small and medium-sized reactors is 51,700 MW, and the cumulative operational experience is 5,082 reactor years.

In China, inland areas and remote areas are limited by geographical location, geology, weather, cooling water sources, transportation, power grid capacity, and capacity. The application of large-scale nuclear power plants is greatly constrained, and small reactors can Meet the power generation needs in these areas.

The “Twelfth Five-Year Plan” to solve a batch of short-board independent innovation is inseparable from investment. In the special scientific and technological projects implemented by China National Nuclear Corporation, the investment in scientific research will grow steadily at a rate of no less than 20% per year after 2010, and the amount of independent R&D investment will reach in 2011. 17.5 billion yuan.

According to reports, during the “12th Five-Year Plan” period, a large number of independent innovation achievements supported by the state will be born to solve a series of shortcomings in the development of China’s nuclear industry, including the development of zirconium alloys, pipes, and nuclear fuel elements with independent intellectual property rights. , Containers for transporting fuel, development of large-scale ground leaching mines, and mine technology, and post-processing plant construction.

During the “Twelfth Five-Year Plan” period, by continuing independent innovation and transforming the mode of economic development, China National Nuclear Corporation will provide technical and personnel protection for the fundamental transformation of China’s nuclear industry from big to strong.
