Abstract

Appearance temperatures and second-law enthalpies of vaporization have been determined for volatile species from cesium uranate and mixtures of CsI-UO₂ and RbI-UO₂ over a temperature range from 900 to 2800 K. Gaseous species effusing from a Knudsen cell were detected using a quadrupole mass spectrometer. The enthalphies suggested which species are present in the cesium-uranium-oxygen condensed phase in the cell at elevated temperatures. This information will assist in the prediction of the chemical nature of fission products that could be released into the containment building under postulated reactor accident conditions.
