Integrated Hydraulic Testing approach for the Characterization of Clay-Rich Sedimentary Rocks

H001 Integrated hydraulic testing approach for the characterization of clay-rich sedimentary rocks Introduction 1 This paper presents the requirements and the characterisation approach to assess the behaviour and properties of clay-rich sedimentary rocks for a high level radioactive (HLW) and spent fuel (SF) waste disposal site. Nagra the Swiss National Cooperative for the Disposal of Radioactive Waste is the organization carrying out this type of site investigations in Switzerland. The Swiss repository concept is a multi-barrier concept where natural and engineered barriers are combined to minimise the flow of water through a repository and limit a potential release of radionuclides
