On September 11, the batch products of gravity support of the International Thermonuclear Experimental Reactor (ITER), which was completely independently developed by China, were officially launched in Zunyi, Guizhou. This equipment is one of the important structural safety components of ITER, which is jointly developed by China Nuclear Industry Southwest Physics Research Institute and Guizhou Aerospace Xinli Technology Co., Ltd; After arriving at the site, it will be installed on the Dewar base ring, which not only bears the weight of tens of thousands of tons of magnet system, but also bears strong thermal stress, strong electromagnetism, transient load and other complex working conditions.
"Artificial sun" is the common name of controllable nuclear fusion device. The development of fusion energy is the ultimate energy dream of global nuclear fusion people who are running from generation to generation, and are committed to illuminating the future of mankind. The International Thermonuclear Experimental Reactor Program is the largest and most far-reaching international scientific project in the world today. China officially signed a contract to join the program in 2006.
ITER is the largest fusion reactor experiment project in the world at present, and its complexity and technical difficulty exceed the fission reactors that have been built and operated in large quantities. ITER magnet support is one of several large-scale procurement packages undertaken by China, which undertakes 100% manufacturing tasks. Gravity support products are the most complex components with the highest manufacturing difficulty in the magnet support procurement package. Its parts are numerous, assembly process is complex, and dimensional accuracy requirements are high. Whether it can be delivered on time is related to the assembly progress of the entire ITER device and the stability of the later experimental device.
Southwest Institute of Physics of Nuclear Industry is the main undertaking unit of China's participation in the ITER program. For more than ten years, it has joined hands with the new aerospace force to jointly tackle key problems, gather the advantages of domestic high-end manufacturing industry, and complete the manufacturing of gravity support products with high quality, demonstrating the level and ability of China's high-end manufacturing. This delivery is the fifth time for NPIC to deliver magnet support products to ITER this year. NPIC will complete all deliveries of this product within the year.
