IV Selected auxiliary data 73
Table IV-2: Selected thermodynamic data for reactions involving auxiliary compounds
and complexes used in the evaluation of thermodynamic data for the NEA TDB Project
data. All ionic species listed in this table are aqueous species. The selection of these
data is described in Chapter VI of [1992GRE/FUG] and [2005OLI/NOL]. Unless noted
otherwise, all data refer to 298.15 K and a pressure of 0.1 MPa and, for aqueous species,
a standard state of infinite dilution (I = 0). The uncertainties listed below each value
represent total uncertainties and correspond in principle to the statistically defined 95%
confidence interval. Systematically, all the values are presented with three digits after
the decimal point, regardless of the significance of these digits. The reference listed for
each entry in this table indicates the NEA TDB Review where the corresponding data
have been adopted as NEA TDB Auxiliary data. The data presented in this table are
available on computer media from the OECD Nuclear Energy Agency.
