Research Abstract

For the safety assessment of the geological disposal of radioactive waste arising from nuclear power generation system, prediction of the migration behaviour of radio nuclides in groundwater is one of the most important subjects, which should be performed based on the detailed understanding of the expected reaction mechanism. Therefore, the thermodynamic quantities (ΔG, ΔH and ΔS) of U(VI) complexation with mono-carboxylic acids, aliphatic di-carboxylic acids and aromatic di-carboxylic acids were determined by the calorimetric measurement.
