Abstract
Since the Fukushima nuclear accident in 2011, nuclear power plants in Japan have taken or are taking the safety countermeasures which are considered on the premise that an accident may occur. These countermeasures include installing and improving the filter vents for preventing contamination of radioiodine. For this reason, silver ion-exchanged zeolite (Rasa-AgX) as a radioiodine adsorbent has been developed and its adsorption characteristics of radioiodine have been investigated. The evaluation results show that Rasa-AgX has the very high adsorption efficiencies even if under the harsh conditions such as high temperature, high humidity and high pressure. In particular, it can still keep the good adsorption performances in the atmosphere of water condensation and at the low DPDs (Dew Point Distances) of zero and 2 K. Owing to these excellent performances, Rasa-AgX is being utilized in filter vent system to capture radioiodine, and it is expected to be applied to more nuclear power plants, reprocessing plants and other nuclear facilities.
