SURVEILLANCE SYSTEM FOR AN ADVANCED SPENT FUEL CONDITIONING PROCESS FACILITY (ACPF)

This paper describes an unattended monitoring system which has been developed to surveil the movement of nuclear material in real time in an ACPF (Advanced spent fuel Conditioning Process Facility). The system consists of cameras for surveillance of the movement of nuclear material, neutron monitors, a neutron counter used as to measure nuclear material, and a data acquisition server for collecting images and radiation signals from these devices. The primary function of the system is to display the results of the image and radiation data which are collected in real time from the surveillance equipment in the forms of graph, figure, and image on a computer screen, to save the image by motion detection for minimizing the amount of storage of the surveillance data, to report automatically using via e-mail in the case of an abnormal situation, to surveil and remotely control the system, to review surveillance data, to convert still images to video to shorten the review time, and so forth. The image saving function by motion detection of the surveillance system, the automatic report function in the case of an abnormal situation, and the video conversion function for shortening the review time, etc. proposed in this paper would help inspectors to carry out their surveillance mission more effectively.
