Nature: The French National Radioactive Waste Management Agency (ANDRA) is testing the feasibility of storing the country’s high-level radioactive waste in an underground site outside the town of Bure in northeastern France. As Nature‘s Declan Butler reports, finding a safe, long-term repository is imperative for France, which generates 80% of its electricity from 58 nuclear power stations. ANDRA picked the site because the area’s Jurassic rock formations are thought to be stable.
