核电设备防腐涂层远程红外成像检测

Remote Infrared Imaging Detection for Anticorrosive Coating of Nuclear Power Equipment

  • 摘要: 核电站核岛内一回路海水冷却系统的管道和储罐表面防腐涂层需要定期检测,为了解决人工检测成本高、效率低、且存在人员安全风险等问题,开发了远程控制脉冲红外成像检测系统,并基于该系统开展了远程红外成像检测试验。结果表明,该系统可以稳定运行,并实现了ZrO2改性Zn-Al-C环氧树脂复合防腐涂层样件中直径2 mm以上界面缺陷的远程红外成像检测。基于该系统,检修人员可以通过远程操作对一回路海水冷却设备的防腐涂层进行质量检测,提高检测效率、降低检测成本,同时避免检修人员长时间暴露在辐射环境中。

     

    Abstract: Anti-corrosion coatings on pipelines and storage tank surfaces in the primary seawater cooling systems of nuclear power plant nuclear islands require regular inspection. To address issues such as high cost, low efficiency, and personnel safety risks associated with manual inspection, a remote-controlled pulsed infrared imaging detection system was developed to conduct a remote infrared imaging detection experiment. The results show that the system operated stably and achieved remote infrared imaging detection of interface defects with a diameter of 2 mm or larger in ZrO2-modified Zn-Al-C epoxy resin composite anticorrosion coating samples. Based on the remote infrared imaging detection system, maintenance personnel can conduct quality inspection of anti-corrosion coating of primary seawater-cooling equipment through remote operation, improving inspection efficiency, reducing inspection costs, and avoiding long-term exposure of maintenance personnel to radiation environments.
