Design Information Verification (DIV) is one of the fundamental cornerstones for the development of a safeguards approach for a facility. Design Information Verification is performed throughout the life cycle of a facility in order to ensure the absence of undeclared design changes and that the safeguards approach remains appropriate and valid. In a large complex facility it is a challenging task to verify the accuracy and completeness of the declared design, and to monitor the modifications and changes that occur during the life of the facility. DIV activities in such a plant require a tremendous investment in human resources, financial resources and time. Large complex facilities also have inherent design features that impose limits on the accuracy, completeness, and continuity of knowledge achievable using traditional DIV methodology. Additionally, physical access to the places of safeguards interest may be difficult. In 2003, the Agency introduced an innovative device - the 3-dimensional Laser Range Finder (3DLRF) – that is capable of meeting some of the challenges involved in performing DIV at large complex facilities. This paper describes the Agency’s experience in using the 3DLRF at the Rokkasho Reprocessing Plant (RRP) in Japan.
