Abstract

<p>For the further advancement of a filter vent, the influence of silver zeolites on the hydrogen recombining reaction has been studied. It is confirmed that the AgX is active and plays an auxiliary role of hydrogen recombiner in the hydrogen catalyst reaction. On the other hand, it has been confirmed that AgX can also remove radioactive iodine in the atmosphere containing hydrogen gas. For AgR, it is proved that it is a kind of special silver zeolite which does not almost have hydrogen catalyst reaction. Owing to these characteristics, AgX and AgR are expected to be utilized under the severe conditions in a containment vessel. In this paper, the development status of these silver zeolites will be introduced, and some possible applications will be proposed.</p>
