Objective
VARIOUS GEOCHEMICAL PROCESSES MAY GOVERN THE MIGRATION OF ACTINIDES IN DEEP GEOLOGICAL AQUIFER SYSTEMS : HYDROLYSIS REACTION, REDOX REACTION, COMPLEXATION WITH INORGANICS AS WELL AS ORGANICS AND COLLOID GENERATIONS. EXPERIENCE SUGGESTS THAT THE COLLOID GENERATION AND COMPLEXATION WITH NATURAL ORGANICS E.G. HUMIC SUBSTANCES APPEAR TO BE THE SIGNIFICANT GEOCHEMICAL PHENOMENA WITH REGARD TO ACTINIDE MIGRATION IN MANY DIFFERENT AQUIFER SYSTEMS.
THE CONTRACT RESEARCH DEALS, THEREFORE, WITH THE COLLOID GENERATION OF REPRESENTATIVE ACTINIDES IN DIFFERENT GROUNDWATERS AND THE COMPLEXATION OF AM AND PU WITH NATURAL ORGANICS, PARTICULARLY HUMIC SUBSTANCES.
THE RESULTS ARE EXPECTED TO GIVE AN INSIGHT INTO THE MIGRATION MECHANISMS OF ACTINIDES IN THE GEOSPHERE.
B.1. ACTINIDE COLLOID GENERATION IN GROUNDWATER
- CHARACTERIZATION OF COLLOIDS
- GENERATION MECHANISMS OF ACTINIDE PSEUDOCOLLOIDS
- QUANTIFICATION OF COLLOID GENERATION AS A MIGRATION MEDIUM FOR ACTINIDES
B.2. ACTINIDE COMPLEXATION WITH NATURAL ORGANICS
- CHARACTERIZATION AND COMPLEXATION STUDY
- HUMIC SUBSTANCES AS ORGANOMETALLIC COLLOIDS
- MOBILITY OF COMPLEX SPECIES AND COLLOIDS IN AQUIFER SYSTEMS
- QUANTIFICATION OF ACTINIDE MOBILITY BY HUMIC SUBSTANCES
B.3. INTERLABORATORY COMPARISON EXERCISE ON COMPLEXATION WITH NATURAL LIGANDS (COCO-GROUP: TUM, CEN/SCK, KUL, CEA-FAR, RISO NAT, LAB,, BGS IRC-ISPRA)
- INTERCOMPARISON OF CHARACTERIZATION METHODS
- SEPARATION AND PRODUCTION OF NATURAL HUMIC ACIDS PRESENT IN THE REFERENCE SITES.
- DETERMINATION OF STABILITY CONSTANTS AND INTERCOMPARISON OF THE RESULTS
