The MEPHISTA-15 database by IRSN (TDmephista)
MEPHISTA (“Multiphase Equilibria in Fuels via Standard Thermodynamic Analysis”) is a self-consistent database specially developed for new generation nuclear fuels by Institut de Radioprotection et de Sûreté Nucléaire (IRSN) in France.
MEPHISTA is consistent with the NUCLEA databases. 14+2 chemical elements are included in the database:
Ba–C–Ce-Cs–Fe-La-Mo-O-Pu-Ru-Si-Sr-U-Zr (+Ar-H).
This database covers the entire field from metal to oxide domains, and the temperature range up to 3500 K. 93 binary, 50 ternary, 2 quaternary systems, 46 solution phases, 236 condensed stoichiometric compounds, and 157 gaseous species are included in the database.
