| Abstract: | The maximum temperature in HLW repository is limited. The maximum temperature is influenced by the repository layout, the geometric dimention of the disposal unit and the thermal parameters of buffer and backfill and the host rock. Construction of the canister,heat released power, thermal conductivity and capacity of the canister is given in KBS-3. The property that thermal conductivity of Bentonite as the buffer changes with saturation and the thermal parameter of the host rock are discussed. The temperature field calculated by means of numerical calculation and the analytical solution in KBS-3 repository is introduced. The uncertainty of the temperature analysis is given.The recent research on thermal problem in China HLW repository is surveyed. |
