초록
Radioisotopes have been widely used throughout industry to optimize processes, solveproblems and improve product quality. A gamma scanning technique using radiation via sealedsource (Co-60) was carried out in order to investigate vertical density profile of catalyst regeneratorof RFCCU. Also through the radiotracer experiments, the flow characteristics of catalyst wasmeasured. The catalyst samples were irradiated with neutron in HANARO reactor to producelanthanum-140 to be used as radiotracer for tracing the catalyst itself in catalyst regenerator ofRFCCU. The radiotracer was monitored around the catalyst regenerator using collimated NaIscintillation detectors. The results of the experiments were used to diagnose the performance ofthe RFCCU.
