Understanding of a post-closure geological environment around a large underground facility is important for the safety assessment of geological disposal of high-level radioactive waste. Japan Atomic Energy Agency (JAEA) has performed the GREET (Groundwater REcovery Experiment in Tunnel) at the Mizunami Underground Research Laboratory (MIU) to evaluate the environmental recovery process after closure. For understanding of coupled behavior of subsurface environment after closure of drift, we perform a Hydro-Mechanical-Chemical coupled simulation of GREET. This study presents the simulation results of excavation stage of test drift for closure test. Our simulation results show that the inflow rate into test drift after excavation is relatively predictable variavle comparing to the hydraulic pressure or chlorite concentration observed in borehole.
