To evaluate chemical behavior of Iodine and Cesium at reactor cooling system in Boron containing environment derived from BWR control materials, a chemical analysis considering chemical reaction kinetic was conducted. Analytical results were compared with those by a chemical equilibrium calculation. It was found that mole fractions of main Cesium compound CsBO were different between those calculated with and without chemical reaction kinetics in a lower temperature condition. This result indicates the necessity of consideration of the chemical reaction kinetic model for the evaluation of the chemical behavior of Iodine and Cesium.
