Visual inspection of fuel channels is an important element of the understanding of the health of the current fleet of AGR reactors. When a fuel channel is inspected, video footage of the entire inside surface is recorded through a series of vertical scans of the channel. When areas of interest such as cracks are identified, screenshots of these areas are taken and manually stitched together to produce a montage of the region of interest. This is a lengthy process, which requires an experienced person to undertake. The resultant montages are assessed and then included in the TV GAP sheet, a document that forms part of the case for return to service. This paper describes an automated approach which uses advanced image processing techniques to recreate a full 360° image of the inside surface of the channel using the same video input. These images offer a significant improvement in the quality over the manual approach, provides 100% coverage of the channel and can be generated in a fraction of the time of the manual images. The software has been applied to over 30 recent channel inspections, and has been demonstrated using footage from all 7 AGR stations.
