To investigate the adsorption behavior of radioactive material for filtered containment venting system, SUS316L was immersed in CsCl. After that, N₂ gas flow was performed, and the amount of radiocesium was evaluated. It was suggested that gamma irradiation reduces the amount of Cs trapped by the metal filter decreases and becomes easy to desorb.
