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.
