摘要：
ASME Section XI, IWE/IWL code requires commercial nuclear power plants to inspect the entire surface area of the containment building - internally and externally. A novel remote visual inspection system was developed and deployed to allow the viewing and cataloging of similar to12,000 square feet of the inside steel liner surface from a distance of 55' with variable magnification to meet the general, VT-3 and VT-1 code requirements of IWE. A semi-automated PC-based system with a mega-pixel digital imaging front-end and 132:1 ratio power zoom lens allows high-magnification, high-resolution, 4-megabyte image files to be databased for future random access, mapping and comparison.
