The chemical/physical properties of Cs-chemisorbed deposit could change along with the progression of LWR severe accident (SA). In this study, the influence of temperature change on the properties of Cs-chemisorbed deposit was investigated experimentally. It was found that Cs-Fe-O compounds, which had been formed by chemisorption at 873 K, could transform into Cs-Si-(Fe)-O compounds at 1273 K.
