Development of radioisotope tracer technology

The project is aimed to develop the radiotracer technology for optimization of industrial process through on-line diagnosis and trouble-shooting and to establish the environmental application of radiation and radioisotopes. The researches for industrial application of radiotracer technology and the development of equipments and software were carried out and the results were employed to the field demonstration experiments for diagnosis and optimization of industrial process units. The radiotracer technology was also applied to digesters, clarifiers and aerators, which are the representative facilities in the environmental plants. CFD (Computational Fluid Dynamics) models on a clarifier were reviewed and modified in terms of RTD and flow distribution pattern by comparing with the radiotracer experiment data. In addition, the radiotracer experiment in rivers supplied very critical information for validating CFD models on rivers and sediment transport study using radiotracer in marine coastal area was initiated
