Our most recent article on gas-bentonite interactions in relation to the gas dynamics in Engineered Barrier Systems is now available on-line as open access publication:
Tomonaga, Y., Wersin, P., Rufer, D., Pastina, B., Koho, P., Ville, H., & Kipfer, R. (2022). Gas-bentonite interactions: Towards a better understanding of gas dynamics in Engineered Barrier Systems. Appl. Geochem., 138, 105205, doi:10.1016/j.apgeochem.2022.105205.
This work represents a first attempt to understand to which extent such interactions can affect the gas dynamics in deep geological repositories.
On Nov. 22nd 2021 we had the opportunity to visit BedrettoLab and collect groundwater samples for noble-gas analysis. A few impressions can be found in the following gallery.
