At the Department of Energy's Hanford Site, underground tanks hold radioactive waste from plutonium processing. A long-awaited cleanup is underway at 114 of the US's nuclear facilities. The nuclear age has produced 52,000 tons of spent fuel from commercial, military and research nuclear reactors, as well as some 91 million gallons of waste from plutonium processing - both are classified as high-level waste, the most dangerously radioactive kind. Radioactivity can last for millions of years. Depleted uranium, contaminated tools, and plutonium itself are among other products of the nuclear industry requiring safe storage. High-level waste in the USA is accumulating at a rate of more than 2,000 tons a year. In addition to waste storage, nuclear reactors must be decommissioned and contaminated soil and groundwater cleaned up.
