In the concept of vertical disposal of high-level radioactive waste, evaluating the influence of groundwater flow into disposal pits on the performance of buffer materials as an engineering barrier is important because the inflow might cause erosion of the buffer materials. In particular, for a rock mass in which fractures control the permeability, it is necessary to evaluate the groundwater behavior around the disposal pit in consideration of fractures in the surrounding rock mass.
