[2P09] Cs chemical reaction with stainless steel under a LWR severe accident

(4)Evaluation of surface reaction rate between Cs and stainless steel for modeling study

*Shunichiro Nishioka2,1, Kunihisa Nakajima1, Eriko Suzuki1, Masahiko Osaka1 (1. JAEA, 2. IRID)

Keywords:cesium, chemisorption

Existing models of Cs chemisorption onto stainless steel (SS), incorporated in the severe accident (SA) analysis code were validated. The surface reaction rates between Cs and SS were calcurated, using new experimental data, and the application range of these models was considered in each atmospheric condition.
