Abstract

In this study, improvements were made to experimental facility which was constructed in order to study the effect of primary circuit surface on the transport of fission products. The improvements included new primary diluter, new automated sampling system, and new sampling program, able to collect more online temperature, pressure and flow rate data. Also, two experiments were conducted in order to test the updated facility and gain new knowledge of the formation of gaseous iodine in different temperatures. The experimental work showed that the results obtained with the updated experimental facility were comparable with the previous experimental work. Further, it was showed that gaseous iodine can be formed in reaction between caesium iodide and molybdenum oxide at 400°C temperature.
