摘　　要：高场侧第一壁作为全超导托卡马克核聚变实验装置(EAST)中面向等离子体部件的重要组成部分,其功能为承受高热负荷和保护真空室内部部件。随着中性束注入(NBI)功率和等离子体运行参数的提升,现有的高场侧NBI束透区第一壁已经不能满足EAST装置高功率、长脉冲的需求。因此,设计了一种组合式的高场侧NBI束透区第一壁面板,每个面板由进出水模块、标准模块和连接模块构成。每个模块均为3层结构,碳纤维复合材料(CFC)作为面向等离子层;无氧铜(OFC)作为中间层;CuCrZr/316L复合金属板作为热沉层。通过仿真软件Ansys对EAST装置高场侧NBI束透区第一壁面板进行了传热和热应力分析,分析结果表明,各部件的材料温度和热应力值均在许用范围内。基于结构设计和热工水力分析,验证了高场侧NBI束透区第一壁设计的可行性。The first wall at high field side is an important part of the plasma-facing component in the experimental advanced superconducting tokamak(EAST),and its function is to withstand high thermal load and protect the vacuum inner components.With the increase of neutral beam injection(NBI)power and plasma operation parameters,the existing first wall in the NBI shine-through area of high magnetic flied side cannot meet the high power and long pulse requirements of EAST.Therefore,a modular pattern NBI shine-through area panel has been designed,each panel contains inlet and outlet water module,standard and connection modules.Each module has a three-layer structure,the carbon fiber composite(CFC)is used as the plasma-facing layer and the oxygen-free copper(OFC)is used as the intermediate layer and the CuCrZr/316L bi-metallic plate used a the heat sink layer.The heat transfer and thermal stress analysis of NBI shine-through area panels are carried out by the simulation software Ansys.The analysis results show that the material temperature and thermal stress are within the allowable range.Based on the structural design and thermal-hydraulic analysis,the design feasibility of the first wall on the NBI shine-through area panels is verified.
