This manual describes the detector design features, performance, and operating characteristics of the Tokai-1 spent fuel monitor. The system includes a pair of monitors-one for the primary (normal) fuel transfer chute and one for the by-pass fuel transfer chute. Each monitor contains four independent detector tubes to provide direction of travel and redundancy. There are two ion chambers and two {sup 3}He tubes inside each detector package. All of the detectors are used to monitor the presence of spent-fuel gamma rays as the fuel rods pass alongside the detector package. Gamma-ray and neutron detector (GRAND) electronics supply power to the ion chambers and {sup 3}He tubes, and the data is collected in the GRAND and the Kontron computer. The system is designed to operate unattended with data pickup by the inspectors on a 90-day period. This manual gives the performance and calibration parameters
