Finland Prepares to Open First Permanent Nuclear Waste Disposal Site

• •Onkalo is the world's first permanent nuclear waste disposal site, set to begin operations soon.
• •The facility can store 6,500 tons of spent nuclear fuel, isolated 430 meters underground.
• •Construction began in 2004, with a total cost of $1.2 billion funded by Finnish nuclear companies.

Finland is set to begin operations at Onkalo, the world's first permanent nuclear waste disposal facility, located 430 meters underground in 1.9-billion-year-old bedrock. Construction of Onkalo began in 2004 on the island of Olkiluoto, and it is designed to safely store 6,500 tons of spent nuclear fuel. The facility aims to isolate radioactive waste from the environment for hundreds of thousands of years. The project, costing $1.2 billion, is funded by Finnish nuclear power companies. Authorities are expected to grant operational licenses within months. The site has been chosen for its geological stability and low earthquake risk. Currently, approximately 400,000 tons of spent nuclear fuel are stored globally, with Onkalo being the first permanent solution. The facility will use unmanned machinery to seal radioactive rods in copper canisters before burial. The final disposal canisters are engineered to remain sealed until radioactivity decreases to safe levels.
