Thermodynamic data of compounds and complexes of metal elements with organic ligands for JAEA-TDB
- 1. Japan Atomic Energy Agency, Geological Isolation Research and Development Directorate, Tokai, Ibaraki (Japan)
Description
The thermodynamic database is used to evaluate solubility-limiting values of radio-nuclides in various types of groundwater for safety assessment of geological disposal for high-level radioactive waste and TRU waste. It is planned that JAEA-TDB has been developed modifying JNC-TDB released in 1999 by the end of FYJ 2009. The JAEA-TDB is planned to include thermodynamic data of compounds and complexes of metal elements with organic ligands which were not included in JNC-TDB. This report shows the selected thermodynamic data of compounds and complexes of metal elements with organic ligands which might be included in TRU waste in JAEA-TDB. Selected organics are oxalic acid, citric acid, ethylenediaminetetraacetic acid (EDTA) and iso-saccharinic acid (ISA) which were of interest in the OECD/NEA. The thermodynamic data evaluated by OECD/NEA were selected for JAEA-TDB. However, selected values by OECD/NEA are limited to evaluate the solubility calculation of radio-nuclides. Therefore, other published values and estimated values by LFER, Liner free energy relationship, are also selected as tentative values for JAEA-TDB. (author)
