Fundamental physical-chemical knowledge and data are required for investigating the feasibility and long-term safety of deep geological disposal.
Laboratory studies can contribute to the required understanding. Examples of work carried out in this connection include diffusion experiments on Opalinus Clay or investigation of the sorption of radionuclides on clay minerals. The data are used for modelling the transport of radionuclides or constructing geochemical models.
In the areas of laboratory studies and modelling, Nagra works together with partners from Switzerland (e.g. the Paul Scherrer Institute and the University of Bern) and abroad (e.g. through participation in EU research programmes).
