核聚变“国家队”成立两月后首次公开亮相，可控核聚变概念股集体上涨

Core Viewpoint - The recent surge in stock prices of fusion energy companies is attributed to the announcement of a new fusion experimental facility by China Fusion Energy Company, which aims to validate its developed high-temperature superconducting magnets [1][2]. Group 1: Company Overview - China Fusion Energy Company, a subsidiary of China National Nuclear Corporation, was established in July and focuses on the design of fusion reactors, high-temperature superconducting magnet technology, and digital fusion reactor development [2]. - The company made its public debut at the 25th China International Industry Fair, showcasing its achievements and future plans, particularly highlighting the advancements made with the China Circulation No. 3 device [2]. Group 2: Technological Developments - The new experimental facility, tentatively named "China Circulation No. 4 (HL-4)," will be built in Shanghai to test high-temperature superconducting magnets, which are crucial for maintaining stable plasma at high temperatures [1][3]. - High-temperature superconducting magnets are expected to significantly enhance the efficiency of magnetic field usage and device design, allowing for smaller and more cost-effective fusion reactors [3]. Group 3: Challenges in Fusion Technology - The industry faces three main challenges: maintaining plasma at over 100 million degrees Celsius for extended periods, the low yield and high cost of tritium fuel, and the material performance requirements for commercial operations subjected to neutron bombardment for 20 years [2][3]. - The next steps for the China Circulation No. 3 device include achieving fusion energy output, with ongoing efforts to address technical challenges related to plasma stability and material durability [3].
