The unofficial files for the TDB developed by the NEA
The following text files have been unofficially created by JAEA using the published data by the Nuclear Energy Agency (NEA) within the Organisation for Economic Co-operation and Development (OECD). The official text file for the PHREEQC geochemical calculation program has been published by the following official Website of the NEA since November 2018: http://www.oecd-nea.org/dbtdb/tdbdata/ We recommend to use the official text file(s) to avoid any implicit errors / inconsistencies.
