THEREDA – Thermodynamic Reference Database [PDF]

Safety of Nuclear Waste Disposal, 2021
Abstract. Part of the process to ensure the safety of radioactive waste disposal is the predictive modeling of the solubility of all relevant toxic components in a complex aqueous solution. To ensure the reliability of thermodynamic equilibrium modeling as well as to facilitate the comparison of such calculations done by different institutions, it is ...

Solid–liquid equilibria of Sorel phases and Mg(OH)2 in the system Na-Mg-Cl-OH-H2O. Part II: Pitzer modeling

Frontiers in Nuclear Engineering, 2023
For geochemical calculations of solubility equilibria between Sorel phases, Mg(OH)2, and oceanic salt solutions, the polythermal THEREDA dataset (based on the HMW model at 25°C) was extended.

Data compilation and evaluation for U(IV) and U(VI) for the Thermodynamic Reference Database THEREDA

, 2015
THEREDA (Thermodynamic Reference Database) is a collaborative project, which has been addressed this challenge. The partners are Helmholtz-Zentrum Dresden-Rossendorf, Karlsruhe Institute of Technology (KIT-INE), Gesellschaft für Anlagen- und Reaktorsicherheit Braunschweig mbH (GRS), TU Bergakademie Freiberg (TUBAF) and AF-Consult Switzerland AG (Baden,

Si–Al Pitzer dataset: Consistent set of Pitzer activity model interaction parameters of Al and Si species, for modelling cements in saline systems with THEREDA

The Si and Al thermodynamic data and Pitzer interaction parameters (IPs) from THEREDA were re-evaluated to extend the applicability of the database for modeling cementitious systems from low to highly saline environments. This study involved reassessing the standard reference thermodynamic data for Si and Al aqueous species and relevant solids (quartz,
