Chemical Thermodynamics of Solid Solutions of Interest in Radioactive Waste Management

This volume provides a state-of-the-art report on the modelling of aqueous-solid solution systems by the combined use of chemical thermodynamics and experimental and computational techniques. These systems are ubiquitous in nature and therefore intrinsic to the understanding and quantification of radionuclide containment and retardation processes present in geological repositories of radioactive waste.  Representative cases for study have been chosen from the radioactive waste literature to illustrate the application of the various approaches. This report has been prepared by a team of four leading experts in the field under the auspices of the OECD/NEA Thermochemical Database (TDB) Project.

PART I: Extended summary

Nuclear Energy Agency

Aqueous-solid solution (Aq-SS) systems are ubiquitous both in natural and anthropogenic environments. In most nuclear waste repositories, solid solutions are intrinsic constituents of the various components of the repository system: from the waste source to the geosphere/biosphere interface.
