PSI/Nagra Chemical Thermodynamic Database 12/07

The Nagra/PSI Chemical Thermodynamic Data Base 01/01 (Nagra/PSI TDB 01/01) has been updated to support the ongoing safety assessments for the planned repositories for low- and intermediate-level (L/ILW) and high-level (HLW) radioactive waste in Switzerland.

The PSI/Nagra Chemical Thermodynamic Database 12/07 is the default database for GEMS-PSI.

This report is a supplement to the documentation of the Nagra/PSI TDB 01/01 and replaces the chapters discussing the data selection for U, Np, Pu, Am, Cm, Tc, Ni, Se, Zr, Th, and Si. All other data contained in the Nagra/PSI TDB 01/01 have been adopted without any change and are neither listed nor discussed in the present report. Thus, e.g., the data concerning Al, Eu, Pd and Sn that were the subject of extensive in-house reviews for the preparation of the Nagra/PSI TDB 01/01 remain unchanged. Older documentation on  core data for aqueous species, minerals, and gases of elements commonly found in natural waters can be found in Nagra/PSI TDB 1992 with supplementary material.
