“…Although the value of K s for sample 1 has been already reported in [1], it was shown again in this paper for comparing to sample 2. By using obtained saturated hydraulic conductivities, the change of effluent water amount from the soil packed bed was calculated.…”

“…In our previous study, the percolation experiment of tritiated water into the soil packed bed were performed. It was supposed that a part of tritium is sorbed by the isotope exchange reaction between tritium in percolating water and hydrogen in soil particles [1]. From the analysis of the change of tritium concentration in the percolated water, it was confirmed that a proposed transfer model for tritium in a soil packed bed presented good agreement with experimental data approximately [2].…”

It is required that the behavior of tritium in the natural soil be clarified to evaluate the impact of the accident for fusion reactor. However, there has been little report on the behavior of tritiated water in the soil. In this study, top face of a soil packed bed was filled by tritiated water and subsequently distilled water was poured in the bed to recover tritium held up in the soil at room temperature. A tritium transport model in the soil has also been established and developed by this study. The tritium transfer phenomena in the soil is considered as percolation and isotope exchange reaction. The tritium transfer model in this study gives good agreement with experimental data for two samples by adjusting overall mass transfer coefficient representing percolation and isotope exchange reaction. It is also found that the value of overall mass transfer coefficient has a proper range for best fitting curve of experimental data of each soil sample.
