2025-05-07 02:50Summary of Key Points from the Conference Call Industry Overview - The fusion energy research in China is experiencing rapid and diversified development, with multiple key projects expected to make continuous progress in technological routes and commercialization exploration [1][2][3]. Key Projects and Investments - The "Fusion Spark One" project in Jiangxi is a benchmark for fission-fusion hybrid reactors, with an initial investment of 16 billion yuan (total investment of 30 billion yuan), designed to achieve a Q value exceeding 15 [2][3]. - The Hefei BEST project by the Chinese Academy of Sciences plans to adopt hybrid magnet technology and aims for completion by 2027, with the first demonstration of fusion energy generation globally [3]. - The Circulation 3 project is focused on a pure deuterium-tritium route, aiming for 100% high-temperature superconducting operation, expected to enter the demonstration phase around 2045 [3]. - The CFETR project, a major national scientific infrastructure, is progressing with subsequent funding, with plans for completion before 2035 [3]. Domestic Component Replacement - There is an acceleration in the domestic replacement of core components, highlighting investment opportunities within the core industrial chain [4]. Core Components of Fusion Devices - Key components of compact tokamak devices include superconducting magnets, first walls, vacuum vessels, core pumps and valves, cooling systems, and divertors [5]. Cost Structure Insights - According to the breakdown of ITER construction costs, core cost components such as magnets and vacuum vessels account for over 50% of the total construction costs [6]. Upstream Material Requirements - The fusion industry chain involves upstream material requirements, including special metals and superconducting tapes. Special metals include special steel, tungsten, and copper, while superconducting tapes are categorized into low-temperature superconducting materials (niobium-titanium, niobium-tin) and high-temperature superconducting materials (YBCO) [7]. Investment Recommendations - Key materials and device segments should be prioritized for investment, as they are expected to benefit from orders during the accelerated deployment of fusion devices [8]. - Recommended stocks include: - Top Picks: Jingda Co., Ltd. (subsidiary Shanghai Superconducting involved in high-temperature superconducting materials), Lianchuang Optoelectronics (superconducting magnet preparation), and Yingjie Electric, Aike Saibo in power and drive systems. - Watch List: Yongding Co., Ltd., Guoguang Electric, Antai Technology in first wall and divertor segments, and Hailu Heavy Industry, Hezhong Intelligent in vacuum pressure vessel segments [9].
