Construction began at Onkalo - Finnish for “hollow” - in 2004, and final trials will be conducted in early 2024. The plan is to encapsulate the used uranium in thick copper shells and bury the up to five-metre-long canisters in the bedrock, before sealing the tunnel with a massive, wedge-shaped and steel-reinforced concrete plug.

Onkalo’s operator Posiva has developed its solution together with the Swedish Nuclear Fuel and Waste Management Company (SKB). But the long-term storage problem has cast a shadow on nuclear projects. Around 400,000 tonnes of used fuel have been discharged from reactors worldwide so far, the World Nuclear Association estimates, most of which is stored in temporary storage facilities near power plants. Environmentalists, however, worry about their safety and warn that disposing radioactive waste carries huge risks. Low-carbon nuclear power has been hailed as a climate-friendly energy source as the world struggles to combat global warming. The Onkalo repository is designed to house a total of 6,500 tonnes of uranium, covering the spent fuel produced by Finland’s five nuclear reactors during their lifetime. The project, which aims to solve the age-old quagmire of what to do with nuclear waste, is nearing completion in a region that is already home to Europe’s largest nuclear reactor. There is a reason the catacomb on the lush island of Olkiluoto was buried 400 metres (1,312 feet) below ground: It will house the world’s first spent nuclear fuel disposal facility.
