Wherever the United States decides to put its high-level nuclear waste, planners must also decide how to store a particularly worrisome component: plutonium. At the Materials Research Society meeting in Boston 2 weeks ago, researchers presented a new scheme for putting plutonium safely under glass. The formulation, involving alkali metals, has the potential to incorporate up to 10% plutonium by weight, much more than other types of waste glass.
