Rationale The deep geological repository is considered the international reference for radioactive waste management. All gas exchanges must be understood in context of feasibility such a repository. technological challenge to continuously monitor wide range gaseous molecules at low concentrations confined spaces. Methods A monitoring station, composed two complementary analyzers, was developed:...

Bentonites are widely used for waste repository systems because of their hydrodynamic, surface and chemical-retention properties. MX 80 bentonite (bentonite of Wyoming) contains approximately 85% Na/Ca-montmorillonite and 15% accessory minerals. The dominant presence of Na/Ca-montmorillonite in this clay mineral could cause it to perform exceptionally well as an engineered barrier for a radioac...

Abstract The vitrification of radioactive waste within glass and subsequent disposal a geological facility (GDF) requires comprehensive understanding the effect dissolution on GDF performance. This paper aims to analyse both high-level intermediate-level (HLW ILW) source terms radionuclide release into geosphere just above vault (the ‘crown’). Radionuclide migration was simulated in GoldSim for...

3D modeling method is divided into geospatial modeling and 3D geological modeling. 3D geological modeling technique has become a favorable tool for people to observe and analyze the geological body enriched in mineral resources. Unlike geospatial modeling, 3D geological modeling must consider various geological conditions affecting spatial shape and petrophysical distribution of geological body...
