Bacterial influence on uranium oxidation reduction reactions : implications for environmental remediation and isotopic composition
… influence on the chemistry and speciation of uranium has some important impacts on the environment, and can be exploited usefully for the purposes of environmental remediation of uranium waste contamination. It is important to understand both from a scientific and environmental perspective how …

The isotope geochemistry of uranium: Igneous petrology, ore deposits, and groundwater contamination
… three geologic settings: basalt differentiation, uranium ore genesis, and the remediation of a uranium-contaminated groundwater system. In the latter two cases, 238U/235U is used as a tracer of uranium reduction. 238U preferentially enters the reduced (solid) U phase, thus analysis of U ores can …

Understanding aggregation of solvating extractants in applied separations
… phosphate (TBP) is used in the Plutonium Uranium Reduction Extraction (PUREX) process for recovering uranium and plutonium from used nuclear fuel. The extractant N,N,N',N'-tetraoctyl diglycolamide (TODGA) is being considered for use in the Actinide Lanthanide Separation (ALSEP) process for …

Rotating Disk Electrode Design for Concentration Measurements in Flowing Molten Chloride Salts
… This could be done with either the plutonium uranium reduction extraction (PUREX) method or the pyroprocessing method. Since PUREX does not have the same level of built-in proliferation resistance as pyroprocessing, pyroprocessing is starting to be seen as a good alternative method. …
