可控核聚变产业观察：JT-60SA—日本、欧洲联合开发核聚变堆

Investment Rating - The industry investment rating is classified as "Buy" based on the positive outlook for the sector and expected performance relative to the benchmark index [7]. Core Insights - The JT-60SA is an advanced international joint nuclear fusion experimental center developed by Japan and Europe, aiming to support the ITER project and explore optimal conditions for fusion power plant construction [2]. - The JT-60SA project has successfully ignited and commenced operations, marking a significant milestone in nuclear fusion history, with ignition achieved in October 2023 [2]. - The project has faced delays due to redesigns and procurement issues, but it is expected to pave the way for commercial nuclear fusion power by 2050 [2]. Summary by Sections Company Overview - The JT-60SA is located near Tokyo at the QST research center and utilizes upgraded infrastructure from previous JT-60 experiments, employing superconducting coils for advanced plasma research [2]. - The experimental team was established in 2022, comprising leaders from both Japan and Europe [2]. Technical Aspects - The JT-60SA does not use deuterium-tritium for fusion experiments but instead employs hydrogen and deuterium to study plasma [2]. - The plasma can be heated to over 100 million degrees Celsius and maintained for 100 seconds [2]. - The heating power of JT-60SA will reach 41 megawatts, utilizing two different heating sources for electrons and ions [2]. Cost Control - The JT-60SA project is cost-effective compared to ITER, being approximately half the size and one-fifth the current of ITER, and it does not utilize D-T reactions, simplifying the system [2]. Future Prospects - The project is expected to require two more years of operation to conduct meaningful physical experiments, with plans for a demonstration power plant (DEMO) by 2050 [2].
