Finland leads the world in nuclear energy storage

03 Dec 2015

A $3.2-billion facility on Olkiluoto, an island off Finland’s west coast, will start storing waste in a deep underground repository from about 2023.

It’s the first of its kind in the world, and will pack up to 6,500 tonnes of uranium into copper canisters. The canisters will be lodged into a network of tunnels cut out of granite bedrock 400 metres underground.

Once the facility is sealed in 2021, it will safely isolate the waste for several hundred thousand years. By then, its radiation levels will be harmless.
