Keywords:filtered containment venting system, stainless steel, radiocesium

To investigate the adsorption behavior of radioactive material for filtered containment venting system during long-term operation, SUS316L was immersed in cesium chloride (CsCl). After that, N2 gas flow was performed, and the removal amount of radioactive Cs was evaluated. As a result, it was suggested that gamma irradiation reduces the Cs trapping ability on SUS316L.
