In order to investigate Cs chemisorption behavior on stainless steel under various severe accident condition, simulated Cs chemisorption tests, the parameteres were temperature and atmosphere, were performed. As the results, Cs chemisorbed amounts were greatly affected by not only temperature but also atmosphere.
