N2 - The ThermoChimie database was first developed in 1995 by Andra, the French national radioactive waste management agency. They were joined by Nuclear Waste Services (NWS) from the UK in 2014, and ONDRAF/NIRAS from Belgium in 2018.
ThermoChimie provides an accurate and consistent set of data specifically chosen for use in modelling the behaviour of radionuclides in waste packages, engineered barriers, and both the near surface and deep geosphere. The database can be used to model the speciation and solubility of a wide range of stable and radioactive elements, organics, and solid phases including cements, clay minerals and degradation products (such as zeolites). The database is suitable for use within the range of conditions expected in both near-surface and geological disposal facilities: pH 6-14, ionic strength up to SIT, Eh within the stability fields of water, and temperatures from 15 to 80°C.
ThermoChimie is intended for use across the radioactive waste management community, to support repository performance assessment, research and development activities and decision making. To maximise their utility the data are therefore provided in formats suitable for use with common geochemical modelling codes. The database can be viewed and downloaded from the project website: https://www.thermochimie-tdb.com/, where additional information and supporting documents are also available.
The objective of the ThermoChimie Benchmark is to produce a benchmarking of the thermodynamic database ThermoChimie against other high quality thermodynamic databases available to the scientific community. The present report is the final report focusing on the comparison between ThermoChimie and the CEMDATA applied to the chemical interactions between a clay and an argillaceous environment.
