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 ...
PROFILING DILUENT/EXTRACTANT/LANTHANIDE COMPLEX INTERACTIONS IN ADVANCED TALSPEAK SEPARATION SYSTEMS
Solvent extraction has generally been the method of choice for the reprocessing of used nuclear fuel. Fundamentally, solvent extraction is based on the differences in solubility of chemical species dissolved in a biphasic ...
High Yield Fission Product Separations and Quantification For Nuclear Forensic Applications
Strontium-90 and its daughter, yttrium-90, have cumulative fission yields of approximately 6 percent from the thermal neutron induced fission of uranium-235. With these high yields, Sr and Y are prevalent following an ...
Influence of Near-Field Materials on the Durability of Nuclear Waste Glass
A reliable and effective method of nuclear waste disposal is necessary for the continuing use of nuclear energy. Borosilicate glasses are the currently accepted method of the disposal of these wastes, though a thorough ...
TECHNETIUM (IV) COMPLEXATION CHEMISTRY WITH POLYAMINO POLYCARBOXYLATE LIGANDS
99Technetium (t½ = 2.1×105 y) constitutes approximately 6.1% of the cumulative yield of thermal 235U thermal fission. In the +7 oxidation state, technetium has high aqueous solubility and forms the anionic structure TcO4- ...
