Na-O-U ternary phase diagram
The Thermodynamics of Advanced Fuels - International Database (TAF-ID) project, which has been running for over 10 years, uses the “Calphad” method to develop a thermodynamic database as a computational tool for understanding fuel materials including advanced technology fuels (ATF). This thermodynamic database allows predicting phase diagrams and thermodynamic properties of the phases.
The project also provides a forum for information exchange, including on thermodynamic models, reviews of experimental data, software evaluation and thermodynamic assessments. TAF-ID brings together 12 organisations from Canada, France, Japan, the Netherlands, Sweden, the United Kingdom, the United States and the European Commission.
Version 22 of the database has now been launched to include new and updated assessments in the following materials systems: Na-U, Na-O, Na-U-O, U-Ru, U-Si, Al-Si-U, Fe-Pu-U, O-N-U. The gas phase data has also been updated in accordance with the latest published information.
The assessment totals for the database have now grown to 44* elements (*Eu, Re & Na systems are separately included), 272 binaries, 151 ternaries and 3 quaternaries.
