Description
Canister temperature will be determined mainly by the radiogenic heat output of the glass, the thermal conductivity of the bentonite backfill and the host rock, and the ambient rock temperature. Canister surface temperatures are expected to be ~150 °C at a few years after emplacement, declining to ~80 °C after 100 a. The canister temperature will affect corrosion rates and will influence the moisture content of the bentonite.
