China's Highest Nuclear Power Equipment in the World Realizes Nationalization of Nuclear Power Construction
January 05 20:05:54, 2023
The first domestic AP1000 nuclear steam generator was started and manufactured by Harbin Electric Group Qinhuangdao Heavy Equipment Co., Ltd., which will make the localization rate of China's nuclear power plants from less than half to fully domesticized, representing the highest level of China's equipment manufacturing.
AP1000 technology is the third-generation nuclear power technology and is currently the world's highest level of nuclear power technology. Compared with the second-generation PWR nuclear power technology commonly used in the world, the AP1000 nuclear power steam generator started and manufactured by Harbin Electric Group Qinhuangdao Heavy Equipment Co., Ltd. uses a “non-active†safety system and has higher safety performance. Harbin Electric Heavy-duty Party Committee, deputy general manager and nuclear power expert Wang Shouge said: “Advanced is because he is inactive. The so-called non-action is a major accident in Japan. After the submergence, the diesel engine fails to enter the water, so it is cooled. No, it causes the core to melt, but if we want this problem to occur, the entire core will be cooled, relying on its own weight, not using electricity, and without any energy, it will automatically cool itself and will not appear similar to this Japanese nuclear power plant. In accidents, safety has to be increased by an order of magnitude.The life expectancy of another nuclear power plant has also increased. Nuclear power plants used to have a 40-year life span, but we are now building for 60 years, and have increased the demand for nuclear power products from materials to manufacturing technology. A big one."
AP1000 nuclear power steam generator represents the world's highest level of pressure equipment manufacturing technology, and occupies a very important position in the realization of nuclear power plants. Li Zhi, director of the Energy Conservation and Scientific Equipment Division of the National Energy Administration, stated: “The key equipment that marks the third-generation nuclear power generation three-generation water press technology such as the AP1000, which is currently the most advanced in the world, is being started and manufactured in China. The current AP1000 evaporator is in China. The machinery manufacturing is the one with the most technical difficulty and the most complicated one. This is a typical high-end machinery manufacturing, and it also marks the level of our national machinery manufacturing."
In the past, AP1000 nuclear power steam generators were mastered in developed countries such as France and the United States. Harbin Electric Power Group Qinhuangdao Heavy Equipment Co., Ltd. broke through a number of technical bottlenecks through introduction, digestion, and absorption. Wang Shouge, the deputy general manager and nuclear power expert, said: “Lastly, the localization rate of many nuclear power plants we built was less than 50%. After this localization, we basically achieved 100% localization, that is, all of our raw materials and spare parts were made locally. self-produce."
China's Chongqin possesses all three-generation nuclear power plant forgings production capacity Recently, China First Heavy (601106) developed the world's first AP1000 nuclear power plant - Sanmen-1 unit regulator underscores began shipping, indicating that China has a fully equipped AP1000 nuclear generation nuclear power plant The production capacity of all forgings in the primary loop and the realization of autonomy and batch production.
The regulator is a key equipment for the primary circuit of the nuclear island of a nuclear power plant. The lower head of the voltage regulator is difficult to manufacture, and the requirements for the strength, toughness and purity of the material are very high. Under the circumstances that other peer companies failed to develop successfully, China has overcome a number of technical difficulties and successfully produced AP1000 regulator lower heads more than 30 days earlier than the six-month planning cycle. The product performance fully meets the technical requirements. This is another major breakthrough in the domesticization of nuclear power equipment following the successful development of AP1000 evaporator tube sheet forgings and reactor pressure vessel forgings.
At present, China Yizhong has become the only company in China capable of providing a full set of large nuclear power castings and forgings as well as nuclear island equipment.
