Finland grants operating license to world's first nuclear waste repository
The Finnish government has granted an operating license to Posiva Oy for the Onkalo repository, the world's first permanent underground facility for the final disposal of spent nuclear fuel. Located in Eurajoki at the Olkiluoto site, the facility is designed to store up to 6,500 tonnes of uranium from Finland's five nuclear reactors.
The repository is situated more than 400 metres underground within 1.9-billion-year-old bedrock. The disposal method involves enclosing spent fuel in corrosion-resistant copper canisters, which are then placed in holes drilled into the bedrock, surrounded by bentonite clay, and sealed with steel-reinforced concrete plugs. This multi-layered system aims to isolate radioactive material for at least 100,000 years.
While the license is a historic milestone, operations will not begin immediately. Posiva must first complete a commissioning phase involving necessary tests and inspections, which must be verified and approved by the Radiation and Nuclear Safety Authority (STUK). A specific start-up schedule has not yet been announced. The license covers the encapsulation plant and the Onkalo repository through the end of 2070.
