This study is to gain a better understanding of mass transfer phenomena in the geological environment as well as to develop technologies for: measurement of the solute transport parameters, model construction, numerical analysis and validation of all those technologies based on the existing information. As part of solute transport study, laboratory experiments were planned to understand the influence of the geological characteristics of fracture on the solute transport parameters, also understand the differences in test results by the different sizes of the samples used for an experiment, and moreover to validate the parameters obtained by numerical analysis.

This study aimed to develop a hydrochemical monitoring system for in-situ groundwater. JAEA has developed the hydrochemical monitoring system which is available at underground facility focused on low-permeable sedimentary rocks. After performance test, it can be demonstrated that the monitoring system is workable completely at 350m depth research gallery.
