This article looked at the simulation model used to control temperature evolution in the field for Swedish nuclear waste repositories. Heat transport properties of rock are known key factors for the repository layout and were measured using the Transient Plane Source (TPS) method. Compared to all samples tested, results found bedrock dominated by deformed granitoid rocks were characterized by relatively high thermal conductivities. ...
This study outlines the design of a final repository for nuclear waste in bedrock, by the Swedish Nuclear Fuel and Waste Management Company. Thermal property testing is required to determine the canister separation distance within the repository. The transient plane source thermal constants analyzer was used to determine the thermal conductivity of anisotropic metagranite on a small-scale (centimeter), while a large-scale experiment was used for the large-scale (meter). The results ...
