Spent Nuclear Fuel Disposal Facility

The world’s first spent nuclear fuel disposal facility will be built in Olkiluoto, on the Eura River. Spent nuclear fuel is packaged in copper canisters that protect the fuel from mechanical stress for up to 100,000 years.

The disposal facility will be excavated to a depth of 400 meters in the bedrock of Olkiluoto and the disposal canisters will be placed in holes drilled in the disposal tunnels. The stable bedrock provides almost unchanging conditions for nuclear fuel and protects against surface temperature fluctuations.

Excavation work began in 2016 and final disposal of nuclear waste is scheduled to begin in the 2020s.
