Keywords:cesium compound, moisture absorbent

Fundamental data of degradation by moisture absorbent of Cs compounds was obtained experimentally so as to contribute to evaluation of the aging degradation behavior of deposited Cs on the structure materials under LWR severe accident condition. It was found the moisture absorbent behavior was varied depending on the chemical form of Cs.
