Experiment on Cs chemisorption behavior onto stainless steel, which can significantly influence Cs distribution and property within nuclear reactor during light water reactor severe accident, was performed under steam atmosphere. The experimental result indicated that a Cs-Cr-O compound was formed instead of Cs-(Fe)-Si-O compounds, which are known to be formed under mixed hydrogen and steam atmospheres.
