Abstract
Gas-phase conversion of UN to water-soluble compounds in NOx-air, NOx-H2O (vapor)-air, or HNO3 (vapor)-air atmosphere (hereinafter, nitrating atmosphere) at temperatures from 298 to 673 K was studied. The use of the oxidizing atmosphere based on NOx gases allows the conversion to be performed at a lower temperature. The process yields both UO3 and hydrates of UO2(NO3)2. The highest conversion of UN to water-soluble compounds, ∼80%, is reached at ∼565 K. In the course of gas-phase conversion in NOx-H2O (vapor)-air and HNO3 (vapor)-air atmospheres, UN transforms into water-soluble compounds (nitrates, hydroxynitrates). The gas-phase conversion of UN in an NOx-H2O (vapor)-air atmosphere occurs less efficiently than that in an HNO3 (vapor)-air atmosphere.
