Abstract

<p>In nuclear power plants, measures against radioactive noble gases are required. Until now, special activated carbon that easily adsorbs noble gases has been used in some nuclear facilities. However, activated carbon has a small adsorption capacity and is greatly affected by other gases and environmental humidity. Therefore, to develop a new adsorbent with high adsorption performance is necessary. At emergency response stations, it is necessary to take measures using air cylinders. It was confirmed that the newly developed silver zeolite XeA has more than 10 times the adsorption efficiency of activated carbon for noble gas adsorption. In this paper, we will report on the basic noble gas adsorption performance of XeA and compare the adsorption performance between XeA and activated carbon.</p>
