AI Technical Summary

Technical Problem

Traditional manual visual inspection of nuclear power plant containment defects is time-consuming, inefficient, and poses safety risks. Existing deep learning-based inspection methods mainly focus on crack detection, failing to fully cover defects such as exposed rebar and repairs.

Method used

Remote acquisition equipment is used to automatically acquire images of the nuclear containment structure, construct a containment defect detection model, combine YOLO v5 and Focal NeXt modules, add an attention mechanism, optimize the loss function, and achieve rapid and accurate detection of various defects, and generate a panoramic unfolded image of the containment structure for visual localization.

Benefits of technology

It enables comprehensive, efficient and accurate inspection of the nuclear containment vessel, reducing inspection costs and risks, and improving the operational efficiency and safety of nuclear power plants.
