On December 9, 1996, the United States Department of Energy issued a Programmatic Environmental Impact Statement that advocated an investigation of two possible alternatives for handling plutonium from decommissioned nuclear weapons. One option is to combine the plutonium with uranium to produce mixed-oxide (MOX) fuel that can be used in conventional nuclear reactor plants. The second alternative is immobilize the plutonium in a glass matrix - a process that is also known as vitrification - and to bury the resulting glass logs deep in the ground. With the first option, raw material useful for producing extremely powerful weapons is converted into a fuel material that cannot explode and cannot be purified without enormous capital investments. As the fuel is consumed in a reactor, the destructive potential of the plutonium gradually disappears since each atom can only fission once. Though this fuel is approximately 10 percent more costly than fuel made from virgin uranium (at current market prices) it is substantially (60-90 percent) less expensive on an energy content basis than competitive fossil fuels. With the second option, former weapons plutonium is bonded with glass into a chemically stable form that cannot be corroded in a natural environment. However, simple glass chemistry can remove purified plutonium from the glass. With this scheme, no plutonium is converted into energy or other products, no income is produced, and the full explosive potential of the plutonium remains for millennia. For people not schooled in the politics of plutonium, it would seem rather obvious which choice should be made. A program allocating funds to study the issue would seem like an excellent candidate for a Golden Fleece award. The reality is that the U.S. government has already spent billions of dollars on this debate during the past twenty years and shows every likelihood of continuing the expenditures without hope of a resolution.
