The Department of Energy/Environmental Management (DOE/EM) is responsible for the management and long-term disposition of a variety of materials located at Rocky Flats Environmental Test Site (RFETS), Hanford, Savannah River, and other DOE sites. The purpose of this work is to measure the recombination rates of hydrogen/oxygen mixtures in contact with pure and impure plutonium oxides and to test the effects of adsorbed water on the surface reactivity. This was accomplished by using a calibrated pressure-volume-temperature (PVT) apparatus to measure the recombination rates, in a fixed volume, as the gas mixture was brought into contact with oxide powders whose temperatures ranged from 50 °C to 300 °C. © 2000 American Institute of Physics.

    The safe storage of plutonium in the form of plutonium oxide (PuO[sub2]) is a major concern in countries with significant plutonium inventories. The goal is to stabilize and package oxide in such a way that the possibility of leaks and failures are unlikely. Currently in Russia, PuO[sub2] is...

    Safe transport and storage of pure and impure plutonium oxides requires an understanding of processes that may generate or consume gases in a confined storage vessel. We have formulated conceptual and calculational models for gas formation from calcined materials. The conceptual model for impure...
