On June 11, 2014 the Gesellschaft fur Nuklear Service (GNS) CASTOR V/21 spent fuel dry storage cask was inspected in-situ at the Idaho Nuclear Technology and Engineering Center (INTEC). The purpose of this inspection is to demonstrate and document the technology necessary to perform inspections of spent fuel dry storage casks. The inspection includes internal temperature measurement, internal radiation measurement, and a visual examination using a bore-scope type camera system inserted through the cask fill/drain penetration. It is concluded from this inspection that in-situ inspections of bolted lid spent fuel storage containers is possible using current camera technologies. Using 3D Phase Measurement Technology, measurements of entities such as cracks or corrosion are possible. The internal surfaces of the CASTOR V/21 cask that were inspected were free of corrosion and exhibited no evidence of degradation. One crack identified in previous inspections was examined and appeared the same as in the previous inspections. (authors)
