Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Bentonite buffer is a key element in a high-level radioactive waste (HLW) repository as it dissipates decay heat from the waste to the surrounding rock. This article looked at Kyeongju bentonite as a candidate buffer material and investigated the dependence of thermal conductivity on various experimental conditions. A thermal analyzer instrument was used to measure thermal conductivity using the transient plane source method. Thermal conductivity was found to increase with ...
