Sweden Starts Building 100,000 Year Storage Site For Spent Nuclear Fuel

Sweden has begun constructing a long-term storage facility for spent nuclear fuel in Forsmark, making it only the second country after Finland to build such a site. It is not expected to be completed until the 2080s, but once finished, it will securely house radioactive waste for up to 100,000 years. The Forsmark final repository, about 150 kilometers north of Stockholm on Sweden’s east coast, will consist of 60 km of tunnels buried 500 meters down in 1.9 billion year old bedrock. It will be the final home for 12,000 tons of spent nuclear fuel, encased in 5 meter long, corrosion-resistent copper capsules that will be packed in clay and buried. The facility will take its first waste in the late 2030s but will not be completed until around 2080 when the tunnels will be backfilled and closed, Sweden’s Nuclear Fuel and Waste Management Company (SKB) said.

The Forsmark repository will cost around 12 billion crowns($1.08 billion) and be paid for by the nuclear industry, SKB said. It will have room to hold all the waste produced by Sweden’s nuclear power plants. However, it will not hold fuel from future reactors. Sweden plans to build 10 more reactors by 2045.
