TL;DR: The development of a steady state plasma flow reactor to investigate gas phase physical and chemical processes that occur at high temperature and atmospheric pressure and the preliminary results of two separate investigations involving the condensation of metal oxides and chemical kinetics of high-temperature gas reactions are discussed.

TL;DR: The results indicate uranium can prefer to be in metastable crystal forms that have higher vapor pressures than the refractory form depending on the oxygen abundance in the surrounding environment, and thus kinetic models are required to fully describe uranium transport subsequent to nuclear incidents.

TL;DR: The high pressure electrical conductivity of UO2 is mediated by variable-range hopping, and it is concluded that the low-pressure fluorite phase coexists with the cotunnite phase up to high pressures.

TL;DR: In this article, materials recovered from a uranium-containing plasma generated by an electric arc were characterized using scanning and transmission electron microscopy, showing that the recovered materials included a variety of crystalline compounds (e.g., UO2, UC2 and UCu5), as well as mixtures of uranium and amorphous glass.
