Detection of Debonding Damage of ITER Blanket Based on Acoustic Emission Method

  • 摘要: 包层是ITER(国际热核聚变实验堆, International Thermonuclear Experimental Reactor)的关键部件之一。包层中第一壁界面脱粘是其主要的损伤形式之一, 因此包层脱粘缺陷检测对ITER的安全运行具有重要意义。采用声发射技术对ITER包层脱粘缺陷的产生和扩展进行检测, 以双层板为对象, 进行了双层板脱粘声发射检测试验; 提出了区域定位法和最小二乘法多传感器的组合定位方法, 实现了对脱粘缺陷的有效定位; 验证了声发射检测方法对ITER包层脱粘缺陷检测的有效性。
    Abstract: The blanket is one of the key parts of ITER (International Thermonuclear Experimental Reactor). Debonding damage is a kind of major damage types of the first wall in blanket structure, therefore the nondestructive testing of debonding damage is of great significance to the safe running of ITER. In this paper, AE (acoustic emission) method is proposed for the detection of debonding damage generation and propagation. The AE experimental setup is established and AE experiment is conducted for debonding damage detection in double-layer plate structure. The damages are effectively located using multi-sensor localization method based on the region localization and least squares principle. Finally, the feasibility of debonding damage detection in ITER blanket using AE method is validated.
