In recent years, China has made significant progress in nuclear fusion energy, accelerating its transition toward engineering applications. As a promising future clean energy source, nuclear fusion offers abundant fuel, inherent safety, and zero carbon emissions. China is advancing through major projects such as the Experimental Advanced Superconducting Tokamak (EAST)—often dubbed the ‘artificial sun’—and the China Fusion Engineering Test Reactor (CFETR), continuously overcoming key technical challenges. In 2023, EAST achieved high-confinement plasma operation for over 400 seconds, setting a world record. Meanwhile, the CFETR has completed its engineering design and is scheduled to be built by around 2035 to conduct deuterium-tritium fusion experiments. China also actively participates in the international ITER (International Thermonuclear Experimental Reactor) project, contributing critical components and technical expertise. These achievements mark China’s steady shift from fusion science experiments toward engineering demonstration and eventual commercialization, offering vital support for global energy transition and carbon neutrality goals.
近年来，中国在核聚变能源领域取得显著进展，加速迈向工程化应用阶段。作为未来清洁能源的重要方向，核聚变具有燃料丰富、安全可靠、无碳排放等优势。中国依托“人造太阳”——全超导托卡马克核聚变实验装置（EAST）和中国聚变工程实验堆（CFETR）等重大项目，持续突破关键技术瓶颈。2023年，EAST实现高约束模式等离子体运行超过400秒，创下世界纪录；同时，CFETR已完成工程设计，计划在2035年前后建成并开展氘氚聚变实验。此外，中国还积极参与国际热核聚变实验堆（ITER）计划，贡献关键部件与技术经验。这些成果标志着中国正从聚变科学实验向工程示范和商业化应用稳步过渡，为全球能源转型和碳中和目标提供重要支撑。
