Water content evolution in the Opalinus Clay: Pre- and post-backfilling observations from the lined and unlined cold sections in the FE experiment Open
Commercial moisture probes were installed in the unlined and lined cold sections in the Full-scale Emplacement (FE) experiment. A grout-based installation method was developed to ensure a good coupling between the probe casing and the rock…

Early thermo-hydraulic-mechanical evolution of bentonite under elevated thermal loads: insights from the HotBENT Experiment Open
Proposals for the geological disposal of high-level radioactive waste incorporate bentonite as a buffer material around the waste canister. However, prolonged exposure to elevated temperatures may affect the buffer's performance. The HotBE…

Sorption behavior of radionuclides in lamprophyre and granodiorite: implications for colloid-mediated transport in crystalline host rocks of Grimsel Test Site Open
The safe long-term disposal of high-level radioactive waste in deep geological repositories requires a thorough understanding of radionuclide (RN) migration at interfaces between host rocks and geoengineered barriers, such as bentonite, pa…

Two-phase flow characterization and modelling in bentonite at various temperatures Open
Bentonite is considered a key buffer material for deep geological repositories. During repository evolution, water and vapour redistribution around the canisters governs several processes affecting the sealing properties of bentonite, such…

HotBENT experiment on quality control of bentonites used for granular bentonite material backfilling and block production Open
The maximum temperature that a geotechnical bentonite barrier in a deep geological repository for radioactive waste can withstand while maintaining its integrity and meeting safety requirements is still an open question. Therefore, an inte…
Reconstructing the Evolution of Foreland Fold‐And‐Thrust Belts Using U‐Pb Calcite Dating: An Integrated Case‐Study From the Easternmost Jura Mountains (Switzerland) Open
This case‐study from the Jura Mountains in the foreland of the European Alps demonstrates how the coupling of subsurface analysis and U‐Pb carbonate dating can provide absolute timing constraints and shortening rate estimates of fold‐and‐t…

The HotBENT Experiment: objectives, design, emplacement and early transient evolution Open
The High Temperature Effects on Bentonite Buffers (HotBENT) Experiment, conducted at the Grimsel Test Site, aims to obtain monitoring and sampling data from an in situ large-scale and long-term test of an engineered barrier system (EBS) co…
Predictive DFN modelling for the Upper Muschelkalk aquifer in the northernmost Swiss Molasse Basin based on vertical and horizontal borehole records Open
The exploration of the underground is a complex, but common task. Structural characterisation of a given sub-surface volume is of interest, for many purposes including deep geological repositories for radioactive waste, exploitation of min…

Methods and uncertainty estimations of 3-D structural modelling in crystalline rocks: a case study Open
Exhumed basement rocks are often dissected by faults, the latter controlling physical parameters such as rock strength, porosity, or permeability. Knowledge on the three-dimensional (3-D) geometry of the fault pattern and its continuation …

Hydrochemical and Isotopic (δ2H, δ18O, 3H) Characterization of Fracture Water in Crystalline Rock (Grimsel, Switzerland) Open
Knowledge on water circulation through crystalline rock is of key interest for radioactive waste disposal, geothermal projects or groundwater supply. This study presents first results of long-term monitoring of fracture groundwater chemica…
Constraints on Evolution and Residence time of Geothermal Water in Granitic Rocks at Grimsel (Switzerland) Open
Thermal spring water (17–28°C) occurring in crystalline rocks at the Grimsel area, Switzerland, represents a mixture of an old geothermal component with a surface-derived, young cold water component. Comparison of chemical and isotope data…
