The Dip Azimuth Vector plots used in resource exploration was utilized to visualize the dominant fracture direction trends at each depth section of borehole data taken from the Monju site. This procedure is one of the domain analysis method of granite. Domain boundaries are intersections of the two dominant fracture orientations providing pipe-like flow paths of groundwater. So, utilization of geological data accumulated at the Monju in this way, contributes application for geological survey for disposal of HLW as well as ground safety assessment for large earthquakes.
