民生证券：可控核聚变产业化进程有望加速 建议持续关注核聚变产业催化

Core Viewpoint - The commercialization of controlled nuclear fusion in China is accelerating, with private enterprises and capital entering the fusion energy sector [1] Group 1: Nuclear Fusion as an Energy Solution - Controlled nuclear fusion is seen as the ultimate solution to human energy problems, simulating the sun's fusion process to generate energy [1] - The process requires three conditions: high temperature (T), certain density (n), and energy confinement time (τE), collectively known as the fusion triple product [1] Group 2: Fusion Technology Routes - Research in nuclear fusion primarily follows two main paths: magnetic confinement and inertial confinement [2] - Magnetic confinement uses strong magnetic fields to contain high-temperature plasma, with major device types including Tokamak, stellarator, and field-reversed configuration (FRC) [2] - Inertial confinement relies on the inertia of particles to achieve fusion before they disperse, primarily using Z-pinch and laser methods [2] Group 3: Project Overview - Notable international projects include ITER (the world's first fully superconducting Tokamak), SPARC (the first high-temperature superconducting Tokamak), and Orion (the first fusion power plant) [3] - In China, key projects are led by major research institutes and private enterprises, including the BEST project (compact fusion experimental device) and the Jiangxi "Spark" project (fusion-fission hybrid reactor) [3] Group 4: Investment Recommendations - The rapid commercialization of the nuclear fusion industry suggests continued attention to catalysts in this sector [4] - Recommended companies include those involved in high-power electronic tubes, vacuum switches, and superconducting materials, among others [4]
