摘　　要：国际热核聚变实验反应堆(ITER)是一项大型的国际合作项目,其中屏蔽包层(即第一壁,FW)模块起到屏蔽中子和冷却的作用。依据FW的组成材料、结构特点、检测要求和超声波在其内部的传播特性,FW结合质量检测需采用宽频超声,针对上述情况,提出宽频超声检测方案,并对其可行性进行了理论分析和研究。International Thermonuclear Experimental Reactor （ITER） is an international cooperative item. One of its components, the First Wall （FW） functioning as neutron shielding and cooling, is an important part. According to the component materials, structural features, testhng requirements of the FW, and the ultrasonic propagation characteristics, it is suggested that Broad-band ultrasonic can be used to test the bonding quality of the FW. According to the ease mentioned above, the Broad-band Ultrasonic Testing scheme was presented, and the ultrasonic testing feasibility was analyzed theoretically in this paper.
