In the areas of plutonium waste disposition and storage, and medium to long-term retrievable Pu materials storage, the issue of water and other small molecule interactions with pure or impure Pu oxide materials and metal has become a major concern. The interaction of PuO[sub 2] with water was investigated from 100 °C to 350 °C using a suite of experimental techniques which include microbalance and pressure-volume-temperature (PVT) methods, thermal gravimetric analysis (TGA), mass spectrometry (MS), x-ray and neutron diffraction. Reaction rates and oxide compositions were determined from measured increases in sample mass or pressure over time (t). Gaseous and solid products were analyzed using MS and diffraction methods, respectively. © 2000 American Institute of Physics.
