The Dependence of equilibrium partition coefficient of cesium and iodine between sodium pool and the inert cover gas on the concentration in the pool

Miyahara, Shinya ; Nishimura, Masahiro ; Nakagiri, Toshio

We measured equilibrium partition coefficients of cesium and iodine between liquid sodium pool and the inert cover gas. The obtained empirical equations were consistent with Castleman's theoretical equations. The effect of cesium concentration upon the partition coefficients was consistent with the theoretical values. That of iodine concentration was incompatible with the theoretical consideration due to the formation of dimmer of NaI (Na $_{2}$ I $_{2}$ ) in the cover gas.
