Abstract: 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 determined that anisotropy is scale dependent, meaning the smaller the scale, the higher the anisotropy, and vice-versa.
