A study on the safety of spent fuel management

In order to establish the effective removal system of radioactive iodine compound generated from the nuclear facilities, study on adsorption and desorption of organic iodine by impregnated active carbon was carried out. Physical characteristics of impregnated active carbon was identified, and the adsorption of water vapor and the methyl iodide adsorption and desorption characteristics by impregnated active carbon were studied. Also, the weathering effects on impregnated active carbon was analyzed to evaluate the long-term capacity of impregnated active carbon. In addition, the existing test facility of impregnated active carbon was partly updated by incorporating sophisticated temperature and humidity controling system. (Author)
