High-level radioactive waste repositories rely on multi-barrier systems, including natural and engineered barriers, crucial for long-term safety through isolation delay functions. Improving the performance of barriers poses challenges, necessitating thorough evaluation via ongoing field surveys lab tests. Natural are categorized analyzed based lithological structural characteristics. Structural elements such as fractures, joints, faults play a role in assessment they can serve pathways...
Rock masses characterized by low permeability (e.g. crystalline rocks) have been considered as natural barriers in the deep geological disposal of high-level radioactive waste. Therefore, groundwater flows within are typically governed spatial distribution fractures rock mass. This study focuses on introducing an experimental system designed to evaluate hydro-mechanical properties barriers. allows experiments fracture specimens employing fluid injection under true triaxial compression...
This presentation describes the results of a study on change in hydrogeological properties that can occur natural barriers after excavating disposal hole. We performed series hydraulic tests at borehole KURT area to understand characteristics around drilling-induced damage zone As result, it was confirmed transmissivity fractured rock increased from several times tens times. It caused by generated surface expanding diameter borehole. In particular, test section with low transmissivity. end,...
