Independent determination of the accuracy of a research reactor stack-gas monitor

;

During normal operation of the Oregon State University TRIGA reactor (OSTR), argon-41 is produced and released to the atmosphere as a gaseous effluent through the reactor building exhaust stack. The reactor facility's stack gas monitor (SGM) continuously samples the effluent in the exhaust stack and simultaneously measures the concentration of argon-41 being released. This study was undertaken to determine the accuracy of the stack gas monitor, using techniques which were independent of the monitoring system itself. The results indicated that the argon-41 concentrations displayed by the stack gas monitor were approximately 50% of those predicted by analysis of individual samples from the exhaust system.
