Summary

This paper reports the results of hydraulic modelling under unsaturated condition around openings in argillaceous formation at the Tournemire site, in order to determine permeability value suitable to explain measured distribution of saturation ratio. We performed modelling with finite element method with consideration of seasonal changes of humidity in the openings. Results of modelling could simulate reasonably well the characteristics of the measured distribution. Modelling results with permeability 10~19m2 to 10~20m2 show good agreement with the measurement results. This study is a part of contribution of Japan Atomic Energy Agency and Kyoto University team to Task C of the DECOVALEX-THMC project.
