Finland Approves World's First Deep-Geologic Nuclear Waste Repository at Onkalo

Finland has authorized the world's first deep-geologic nuclear waste repository at Onkalo, designed to store 6,500 tons of spent fuel in copper capsules at 400 meters depth, with operations expected to continue until around 2120. The facility will be sealed and left to operate without electricity or supervision, though local debate persists over whether closure should be final. This marks a first-of-its-kind permanent solution for high-level nuclear waste, setting a precedent for other nations.
