Finnish Deep Nuclear Waste Disposal Reaches Milestone

Nuclear waste disposal tunnel at Onkalo Facility in Finland, 2022

Finland is leading the world when it comes to permanently disposing of spent nuclear fuel in a deep geologic repository. Their Onkalo facility recently completed excavation of the first of five final disposal tunnels, a 1.7 km long tunnel. Ground Engineering magazine has a nice article about the project and the recent milestone, but there is a very cool article by BusinessInsider.com where their science reporter got a tour of the facility and has lots of great photos and videos. If you really want to see how the facility will operate, check out that article. One of the videos is shown below, an animation of how the waste capsules will be stored in vertical shafts extending below the main disposal tunnels.
