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.
