Nuclear fuels ceramic

The performance requirements for ceramic nuclear fuel elements include the following dimensional stability to high fuel burnups, fission product retention, corrosion resistance, high thermal performance, fabricability, economic advantage, inspectability, and chemical reprocessing and recycling.

HIGH TEMPERATURE CHEMISTRY OF CERAMIC NUCLEAR FUELS WITH EMPHASIS ON NONSTOICHIOMETRY... 

The present review will cover the phase equilibria of these ceramic nuclear fuels at high temperatures, and a summary will be given on their nonstoichiometric region, defect structure and thermodynamic data. In addition, diffusion and vaporization processes will be taken as representative phenomena eharacteristic of these materials at high temperatures, and these phenomena also will be reviewed in their relation to nonstoichiometry.
