COORDINATION CHEMISTRY OF f-ELEMENTS IN THE TALSPEAK PROCESS
A key step in the advancement of the nuclear fuel cycle in the U.S. is transmutation of the long-lived activation product actinides (Am3+ and Cm3+). Transmutation is viable once the minor actinides Am3+ and Cm3+ have been ...
Lanthanide-Polyaminopolycarboxylate Complexation Kinetics in High Lactate Media: Investigating the Aqueous Phase of TALSPEAK
In advanced nuclear fuel reprocessing schemes, the TALSPEAK (Trivalent Actinide Lanthanide Separation with Phosphorus-reagent Extraction from Aqueous Komplexes) process has been proposed as a means to separate Am and Cm ...
UTILIZATION OF TRADITIONAL AND NOVEL NMR SPECTROSCOPIC TECHNIQUES TO PROBE INTERACTIONS IN THE ORGANIC PHASE OF LIQUID-LIQUID SOLVENT EXTRACTION SYSTEMS
Solvent extraction is a technique commonly used is the reprocessing of used nuclear fuel elements. It utilizes the partitioning of a metal ion between two immiscible phases, typically an acidic aqueous phase and a light ...
Synthesis and Characterization of Aqueous Pyridine Ligands for Actinide Lanthanide Separation
Responsible stewardship of used nuclear fuel requires the operation of a closed nuclear fuel cycle and proper management of the actinide materials through transmutation. The separation and isolation of the minor actinides ...
ASSESSING MEDIUM EFFECTS IN TALSPEAK-LIKE SYSTEMS VIA CALORIMETRIC ENTROPY TITRATIONS
This study investigated the application of calorimetric entropy titrations to the light lanthanides in TALSPEAK-like systems. Since TALSPEAK operates in an unusual ionic medium, this work was expanded to probe medium effects ...
