It is necessary to clarify the mass transport behavior in a deep underground natural barrier, for improving the reliability of safety assessment of high-level radioactive waste disposal. This study reports an analysis using data from in situ tracer tests for fractures in mudstone at Horonobe Underground Research Laboratory (URL).
