Finland Opens Onkalo Nuclear Waste Facility

Finland is set to open Onkalo, the world's first permanent underground repository for spent nuclear fuel, after decades of construction. Located on the island of Olkiluoto, the facility, managed by Posiva, will store 6,500 tons of radioactive waste in 1.9-billion-year-old bedrock. The project, costing approximately 1 billion euros, aims to provide a safe, long-term solution for nuclear waste, with canisters designed to contain radioactivity for hundreds of thousands of years. Finland's environment minister, Sari Multala, emphasized the country's commitment to domestic waste management and hinted at the possibility of accepting limited international waste. However, Edwin Lyman of the Union of Concerned Scientists highlights uncertainties regarding canister corrosion and the long-term risks to future generations, including potential for sabotage if waste is not properly secured. The International — International Atomic Energy Agency reports that globally, nearly 400,000 tons of spent fuel have been produced, with most still in temporary storage, underscoring the global significance of Finland's pioneering effort.
