The explosive gases such as hydrogen and CO will be generated in a severe accident (SA). We conducted joint research with the Swiss research institute PSI on the hydrogen catalytic properties of AgX and AgR under various conditions. Last year, we reported that the hydrogen catalytic reactivity is strong for AgX and weak for AgR. In this paper, we will report on the effects of coexisting gases such as CO. The experimental results shows that CO does not interfere with hydrogen catalysis reactivity. Furthermore, it is confirmed that AgX has an oxidizing effect on CO since CO concentration decreases and CO2 concentration increases when CO flows through AgX. As a result, we propose to utilize these characteristics as countermeasures against hydrogen and CO generated during SA.
