Posiva begins drilling disposal holes at Finland’s Onkalo repository
Last week the Finnish nuclear waste management company Posiva began drilling holes for final disposal at the Onkalo deep geological repository, near the Olkiluoto nuclear power plant in western Finland. The company’s German-made Deposition Hole Boring Machine (DHBM) took about 10 hours to drill the first hole, with a depth of 8.4 meters and a diameter of 1.75 meters, into the 1.9-billion-year-old bedrock. This is the first deposition hole intended for an iron-copper canister containing spent nuclear fuel—though test holes have been drilled at the site since 2022.
The Onkalo repository received a favorable safety assessment from the Radiation and Nuclear Safety Authority of Finland earlier in August.
