The United States has generated over 75,000 metric tons of spent nuclear fuel and high-level nuclear waste--extremely hazardous substances--at 80 sites in 35 states and is expected to more than double that amount by 2055. The Nuclear Waste Policy Act of 1982 (NWPA) required the Department of Energy (DOE) to investigate a geologic repository for nuclear waste. In 1987, Congress amended NWPA to dire...
