JAEA have been developing the Geological-Evolutionary Models (GEMs) taking into account of long-term change of the geological environment in order to evaluate the geosphere stability.
This paper summarized the current status of R&D activities with analysis on effects of uncertainties of GEMs for evaluation of long-term variability of groundwater flow conditions.
