NEA Clay Club annual meeting, 23 September 2020.

An evaluation of the occurrence of fluid flow through faults and fractures is of primary importance for the performance assessment of radioactive waste repositories located in argillaceous settings.

One of the initiatives of the Clay Club has been to launch a compilation and a review of the relevant literature on the basic concepts and mechanisms which control the movement of water, solute and g...

The definition of the chemical and isotopic composition of the groundwater present in argillaceous formations, which are considered as potential host rocks for radioactive waste disposal, is crucial ...

Most experts worldwide agree that radioactive waste disposal in engineered facilities, or repositories, located in appropriate formations deep underground, provide a suitable waste management option ...

The Clay Club promotes the exchange of information, shared approaches and methods to develop and document an understanding of clay media as a host rock for a repository.
