Thermodynamics and vapourization of Cs-, Sr-, Ba-containing oxide systems valid for nuclear safety problems

Abstract

The review provides a systematic analysis of the studies carried out mainly in the last decade in which the thermodynamic properties and vapourization of the systems containing cesium, strontium, and barium were studied by high-temperature mass spectrometry. Such systems are of particular interest for considering the problems of environmental safety in the nuclear power industry. Particular attention is paid to the issues of reliable identification of the content of the gaseous phase over oxide systems, which are important in various high-temperature technologies, including the disposal of radioactive waste, reprocessing of nuclear fuel, as well as ensuring the safe operation of nuclear power plants. A discussion and comparison of thermodynamic data found in the literature for the systems under consideration in a wide temperature range were also carried out featuring the main advantages of the Knudsen mass spectrometric effusion method.<br> The bibliography includes 117 references.
