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.

With the move to a clean energy agenda internationally there is an increased focus on advanced reactor technologies that provide flexible power, heat, hydrogen and desalination solutions. With any new reactor system there is an associated fuel Cycle that accompanies it. This international panel explores the spent fuel and overall fuel cycle challenges that need to be addressed for these new reactor types to be successfully deployed in a timescale that will meet the market demand. There will be a particular focus on where future fuel cycles and waste management requirements may be significantly different to the current systems, and therefore the need for future research and innovation. It will explore current international research and innovation programs and the areas where international collaboration can contribute and accelerate the programs.
