This manual describes the detector design features, performance, and operating characteristics of the Fugen reactor gate monitor for monitoring fresh and spent fuel transfers between the core and storage ponds. This system consists of two monitors located at each end of the transfer chute. The larger monitor contains two {sup 3}He tubes, two fission chambers, and two ion chambers. The smaller monitor, used for direction of motion redundancy, contains two ion chambers. All detectors provide information for identifying the type, fresh or spent UOX or MOX fuel, and direction of the fuel transfer. The gamma-ray and neutron detector (GRAND-3) electronics package supplies power to the radiation sensors and collects the radiation data for storage on a laptop computer. The system is designed to operate unattended with data collection by the inspectors occurring on 90-day time intervals. This manual also includes radiation data for the six types of fuel transfers and equipment transfers along with the direction of motion information collected during the installation at the Fugen reactor
