Deep Geological Repositories are the world’s scientifically-accepted method for long-term storage of used nuclear fuel. Many countries which have benefitted from nuclear power for decades are progressing plans for DGRs.
In Finland, used fuel from the nuclear power plants of Teollisuuden Voima and Fortum will be packed in copper canisters and embedded in Olkiluoto bedrock at a depth of 400-450 metres.
France began researching ways to safely manage its nuclear fuel in 1991, finally deciding in 2006 that a DGR was the most scientifically-sound method.
The United Kingdom has plans to build a Geological Disposal Facility and is currently undergoing a site selection process, similar to the Nuclear Waste Management Organization.
