Abstract
Radionuclide released from corroded container migrates through groundwater flow pathway in the underground rock. Therefore it is important to study the groundwater flow analysis for total system performance assessment of a HLW repository. In this study assuming a geological change of underground rock in future, the two dimensional groundwater flow analysis is done by the NAMMU, the assessment code for groundwater flow in porous media. Assuming the hypothetical repository with the reactivation of fault in the vicinity of it, the effect of change in aperture and permeability by reactivation of fault around a repository on groundwater pathway is studied.
