It is known that heavier hydrogen isotope is enriched in ice under equilibrium of ice-water two phase system. However, partition coefficient of HTO has been scarcely reported. In this study, the partition coefficient of HTO in water-ice two phase system was evaluated at 0 °C. The initial HTO concentration in ice and water was set at 50 Bq/g. The value thus obtained was 1.05.
