Summary: |
This report presents the updated analyses for thermal dimensioning of the KBS-3V type spent nuclear fuel repository in Olkiluoto. This report concerns only the thermal dimensioning of the repository and does not take into account the restrictions caused by the rock mechanical stresses. The maximum temperature on the canister-bentonite interface is limited to the design temperature of +100°C. For the reasons presented in this report, due to uncertainties in thermal analysis parameters the nominal calculated maximum canister temperature is set to 95°C having thus a safety margin of 5°C. The maximum temperature can be con-trolled by adjusting the space between adjacent canisters, or adjacent tunnels, or the decay heat power of the canisters, for example. |
