Short summary
Short summary
The Repository Site Selection Act explicitly emphasises that targeting the disposal of high-level radioactive waste is a so-called learning process. We are of the opinion that the procedure and the available data should be combined with geoscientific knowledge to support the identification of siting regions. We propose this workshop and invite all experts who have dealt with the search for a repository site from a geoscientific perspective.

Short summary
Short summary
The present contribution provides an overview on the collaborative project iCROSS and reports selected results. The impact of considering complex coupled processes in repository subsystems for the assessment of the integrity of a given (generic) repository arrangement will be discussed. The interdisciplinary team combines experimental work in the lab, in the underground rock laboratory and environmental simulations in order to achieve process understanding across variable scales.
Short summary
We studied dissolution and precipitation in fully saturated porous media to validate the underlying concepts of reactive transport modeling. Our methods, including
lab-on-a-chiptechnology that combined high-resolution microscopy and confocal Raman spectroscopy gave insights into the important pore-scale features for realistic simulations of real subsurface systems.
