Abstract
In order to estimate the effects of coupled thermal-hydraulic-mechanical phenomena in near-field for geological disposal of high-level radioactive waste on a vast groundwater flow system, a far-field anlaysis was simulated based on the results of the simulation of coupled phenomena in near-field using averaged tensor and heat flux.
From the results of the coupled analyses of near-field and far-fled it was clarified that groundwater flow system was influenced by coupled phenomena in near-field. Moreover, it can be said that groundwater flux into a disposal tunnel is regarded as a complement to safety assessment of a disposal because it strongly correlates with traveling time of groundwater.
