In this series of presentations, we will report on research aimed at clarifying the solid-liquid distribution behavior and mechanism between C-14 in the liquid phase and solid phases such as cement and carbonate minerals, based on the analysis results of both solid and liquid phases, and constructing a long-term behavior evaluation model for C-14 in waste and a more effective cement-based engineering barrier system. In this study, we attempted an analytical evaluation of the influence of differences in the formation process of carbonate minerals in cement on the migration behavior of C-14 using a simple model based on the estimated mechanism.
