[Praise for China] Chapter of Youth｜Thousand-year "dream of chasing the sun", today's scientific and technological innovation is "creating the sun"

On September 5, a group of commentators from the online theme event "Praising China·Chasing Dreams in a New Journey" visited Hefei Future Science City, focusing on visiting CRAFT "Kuafu", a comprehensive research facility for key systems of fusion reactor mainframes. The research team had an on-site understanding of the development and acceptance results of multiple core subsystems of the device, a close-up experience of my country’s hard-core scientific research capabilities in the field of controllable nuclear fusion engineering, and a glimpse of the future development of clean energy.

Myths shine into reality, and fusion exploration anchors new coordinates. Kuafu Zhuri is an ancient romantic imagination rooted in Chinese culture, carrying mankind's eternal yearning for light and inexhaustible energy. Today, this vision spanning thousands of years is taking root in Hefei’s Great Science Park, transforming it into real scientific and technological breakthroughs. The fusion reactor host key system comprehensive research facility "CRAFT" (CRAFT) here in Hefei Future Science City is the first large-scale scientific device of the Hefei Comprehensive National Science Center and an important part of the future "artificial sun". From chasing dreams day by day in mythology to building suns in situ in science and technology, the advancement of China's nuclear fusion industry is a vivid epitome of the self-reliance and self-reliance of my country's cutting-edge science and technology...Through the "lens" of observation, the public can clearly see that my country's controllable nuclear fusion industry has long bid farewell to pure theoretical exploration and entered a new stage of engineering and systematization.

The hard-core device was put into operation and laid a solid foundation for the core of fusion research. The confidence for technological breakthroughs comes from solid infrastructure layout. The "Kuafu" facility in the park is the first large-scale scientific installation of the Hefei Comprehensive National Science Center, and serves as the core carrier for the future research and development of "artificial sun". The one-eighth vacuum chamber and overall installation experimental platform displayed in the park intuitively demonstrate the precision technology and engineering strength of the fusion reactor host research and development. The supporting fully superconducting tokamak nuclear fusion experimental device model and compact fusion energy experimental device park sand table have established a multi-level, full-chain R&D system, covering all aspects of experimental simulation, engineering construction, and overall layout, and have made up for the key shortcomings of my country's fusion engineering verification.

Scientific research is iteratively upgraded to achieve a leap from catching up to leading. Nuclear fusion is regarded as the ultimate clean energy for mankind. It can simulate the solar energy generation mechanism and has the unique advantages of cleanness, efficiency and abundant reserves. It is the key path to solve the global energy crisis and promote green development. In the early years, my country's fusion research was mostly based on follow-up exploration. Now, relying on the cluster advantages of Hefei's series of large scientific facilities, an independent and controllable R&D system has been formed. From the iteration of basic experimental equipment, to the implementation of the "Kuafu" large-scale engineering facilities, to the planning and layout of new experimental equipment... my country's fusion research has formed a development pattern of progressive and coordinated development, and has established a core position in the global cutting-edge scientific research track.

Science and technology innovation empowers development and activates new energy drivers in the future. The value of large scientific devices has never been limited to breakthroughs in a single scientific research field, but can also drive all-round upgrades of industry, technology, and talents. The continuous improvement of Hefei's fusion facility cluster will not only promote independent research on nuclear fusion core technology and key components, but also promote the clustered development of upstream and downstream industrial chains, providing technical support for new energy, high-end manufacturing, new materials and other fields. The ancient "Kuafu Chasing the Sun" sculpture stands in the park. It is not only a continuation of cultural symbols, but also the epitome of the spirit of Chinese scientific researchers who persist in exploration and pursue light.

Use the power of scientific and technological innovation to write daily answers to the new era. Relying on the continuous improvement of the large scientific device system, the step-by-step pace of scientific research, and the accumulated scientific and technological strength, my country is steadily advancing fusion energy from experimental exploration to engineering applications. In the future, this fertile ground for scientific research will continue to output innovative results, empower green and low-carbon development with hard-core technology, and contribute China's strength to the global clean energy revolution.
