The decommissioning of the Maine Yankee nuclear power plant has required the disposal of many large components, including the inner shroud of the reactor vessel, shown here. Submerged in water, the radioactive shroud produces an eerie glow as the result of Cherenkov radiation. Other waste from the plant includes the spent fuel generated over its 24 years of operation. As with all commercial nuclear plants, this spent fuel contains plutonium, which can be used to fabricate nuclear weapons. In "Thorium Fuel for Nuclear Energy," Mujid S. Kazimi discusses how the use of thorium-based fuels could help prevent the diversion of spent-fuel plutonium to bomb-making. (Courtesy of the Maine Yankee Atomic Power Company and Framatome ANP.)
