The UNWRAP system: A true-color borescope-video system for inspection of tritium reservoir fill stems

The Savannah River Laboratory (SRL) has demonstrated the feasibility of producing undistorted true-color images of bore surface of 1/16- inch-ID stainless steel tubes using a borescope-video system. The system was assembled from commercially available components costing about $33,000. Images may be stored on magnetic disks or film for later reference. Color analyses of images can detect discoloration caused by corrosion, oxidation or contamination that could cause poor quality pinch welds. 4 figs., 2 tabs.
