Influence of Thermal Treatment on the Thermal Conductivity of Beishan Granite

Granitic rocks are potential rock types for hosting high-level radioactive waste (HLW) repositories at depth. A better understanding of rock thermal conductivity is essential to develop HLW repositories successfully. In this work, experimental investigations on the thermal conductivity of thermally treated Beishan granite were conducted. Disk specimens preconditioned at 105 °C were heated to different temperatures (200, 300, 400, 550, 650, and...
