【机械制造】BEST 杜瓦顺利落位安装，行业有望迎密集招标期 ——可控核聚变行业系列报告之一（陈佳宁/汲萌/夏天宇）

Core Viewpoint - The successful assembly of the Dewar base for the BEST project marks a significant milestone in China's fusion energy development, indicating a new phase in the construction of the project and the potential acceleration of component development and engineering installation [4][5]. Group 1: Project Progress - The BEST project has advanced its overall assembly schedule, starting on May 1, 2025, two months ahead of the original timeline [5]. - Multiple projects in the domestic fusion industry are progressing steadily, with new routes and projects being announced, suggesting an upcoming period of intensive bidding [6]. - The "Xinghuo No. 1" project has begun environmental assessments and approvals, aiming for completion by the end of 2029 [6]. Group 2: Technological Breakthroughs - Key technological advancements are being made, such as the introduction of a kilometer-scale REBCO superconducting tape suitable for controlled nuclear fusion scenarios, achieving critical currents of 1299A and 1340A under specific conditions [6]. - A fully superconducting magnet developed by the Institute of Plasma Physics successfully generated a steady-state strong magnetic field of 351,000 Gauss [6]. - Significant progress in plasma intelligent control has been reported, with research results published in a journal under Nature [6]. Group 3: Strategic Value of Fusion Energy - The demand for electricity from data centers is projected to account for 5%-9% of global electricity consumption by 2050, driven by cloud computing, cryptocurrency, and AI [7]. - Major AI companies are increasingly investing in fusion energy, with Helion announcing a power purchase agreement with Microsoft for 50MW of commercial fusion power starting in 2028 [7]. - The cost structure of the controlled nuclear fusion industry indicates that high-value segments, such as magnet systems and vacuum chambers, will benefit from ongoing advancements in the industry [7].
