On the chemisorption of Cs onto stainless steel structural material

Yamashita, Shinichiro   ; Miwa, Shuhei  ; Osaka, Masahiko  ; Nagase, Fumihisa 

Cesium (Cs) chemisorption behavior onto stainless steel (SS) structural materials under LWR severe accident conditions was investigated by means of a chemical equilibrium calculation. Two categories of compounds formed by the Cs-chemisorption onto the SS were identified by a literature review, i.e. Cs-Cr-O and Cs-Si-O system compounds. The chemical stability of Cs-including compounds was evaluated by a chemical equilibrium calculation as a function of oxygen potential. Results showed that Cs-Si-O compounds were stable under a wide range of oxygen potential, while Cs-Cr-O was formed under a limited range. It was also shown that B inclusion might suppress the formation of Cs-Si-O compounds by a formation of Cs-B-O vapor.
