Located in Hefei, Anhui Province, EAST is the world’s first fully superconducting tokamak device, designed to explore clean and nearly limitless nuclear fusion energy. On January 20, 2025, the EAST team achieved a major breakthrough: maintaining a 100-million-degree Celsius plasma for 1,066 seconds. This is the longest stable operation of high-confinement plasma in tokamak history, far exceeding previous global records. Unlike traditional fossil fuels, nuclear fusion produces no greenhouse gases or long-term radioactive waste, making it a key solution to global energy shortages and climate change. The success of EAST is the result of over 20 years of hard work by Chinese scientists and engineers. They overcame countless technical challenges in superconducting materials, plasma control and device stability. The project also involves international cooperation, with researchers from over 30 countries contributing to related research. Looking ahead, EAST will continue to conduct in-depth experiments to optimize fusion technology. Experts believe that nuclear fusion energy could be commercially available within 30 years. As a pioneer in the field, China is leading the global exploration of clean energy and contributing to a sustainable future for humanity. ( ) 1. Where is China’s EAST “Artificial Sun” located? A.
