Abstract
An unattended system for monitoring spent-fuel movement in the storage area of a reprocessing facility has been developed and tested. The system uses radiation detectors to determine when fuel is being moved and a video system to record images of the container movement. In addition to the recorded image, other recorded data include the date and time of the movement and \"fingerprint\" information from the radiation detectors. The direction of motion either into or out of the storage pond is indicated on the video image and on the printed readout. This system was extensively tested at the Sellafield Facility in the United Kingdom. This paper gives the details of the system design and presents results of the field evaluation.
