SANTA FE, NM. U.S.A. SEPTEMBER 13-18, 2015 15th International Conference on the Chemistry and Migration Behaviour of Actinides and Fission Products in the Geosphere Migration 2015 Abstracts Santa Fe Community Convention Center Santa Fe, USA September 13 – 18, 2015 Abstracts Book This Page Intentionally Blank - ii - Background The MIGRATION conferences provide an international forum for the timely exchange of scientific information on chemical processes controlling the migration behaviour of actinides and fission products in natural aquifer systems. Experimental investigations and predictive modelling of these processes are the main topics of the conferences. The information generated from the MIGRATION conferences is the basis for the mechanistic understanding of the migration behaviour of long-lived radionuclides in the geosphere, which is essential for the long-term performance assessment of nuclear waste disposal. The first MIGRATION conference was held in 1987 in Munich, Germany. It was followed by MIGRATION ‘89 in Monterey, California, USA; MIGRATION ‘91 in Jerez de la Frontera, Spain; MIGRATION ‘93 in Charleston, South Carolina, USA; MIGRATION ‘95 in Saint-Malo, France; MIGRATION ‘97 in Sendai, Japan, MIGRATION ‘99 at Lake Tahoe, Nevada, USA, MIGRATION ‘01 in Bregenz, Austria, MIGRATION ‘03 in Gyeongju, Korea, MIGRATION ‘05 in Avignon, France, MIGRATION ‘07 in Munich, MIGRATION ’09 in Kennewick, Washington, USA, Migration 2011 in Beijing, China and Migration 2013 in Brighton, UK. - iii - Scope The MIGRATION conferences focus on recent developments in the fundamental chemistry of actinides, fission and activation products in natural aquifer systems, their interactions and migration in the geosphere, and the processes involved in modelling their geochemical behaviour. The sessions in MIGRATION’15 cover the following areas: A Aquatic chemistry of actinides and fission products 1) Solubility and dissolution 2) Solid solution and secondary phase formation 3) Complexation with inorganic and organic ligands 4) Redox reactions and radiolysis effects 5) Solid-water interface reactions 6) Colloid formation 7) Experimental methods 8) Computational chemistry B Migration behaviour of radionuclides 1) Sorption/desorption phenomena in dynamic systems 2) Diffusion and other migration processes 3) Colloid migration 4) Effects of biological and organic materials 5) Field and large scale experiments 6) Natural analogues C Geochemical and transport modelling 1) Data selection and evaluation 2) Coupling chemistry and transport 3) Development and application of models 4) Model validation 5) Safety assessment and repository concepts Repository and Remediation Programmes in the US International Programmes - iv - Conference Committees International Steering Committee: H.
