Nuclear power comes with the inherent responsibility to dispose of nuclear waste properly and permanently on human timescales. Reductive precipitation of U from its soluble +6 valence to the insoluble +4 valence is a long-standing strategy for reducing U concentrations at spill sites and in natural settings where groundwaters high in U leached naturally from aquifer rocks exist. Previous authors (Bopp, 2010; Brennecka, 2010; Jemison, 2016) have established methods that use 238U/235U isotopic ratios to establish the effectiveness of remediation techniques and also distinguish reductive precipitation from sorption, a process which may lower U concentrations but only for a short time.

With a combination of 238U/235U, δ238U and 234U/238U we were able to notice a general trend of slight positive correlation between δ238U and U concentration, and perhaps most notably, trends within aquifer substrates that imply that δ238U can be used to detect whether reduction has occurred in natural systems."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["The role of chemical reduction in decreasing uranium concentrations in natural groundwaters: A case study from India"]}]}],"canonical_facts":{"dc:contributor":["Lundstrom, Craig C"],"dc:creator":["Akrie, Perry"],"dc:date":["2022-05","2022-04-27"],"dc:description":["The student, Perry Akrie, accepted the attached license on 2022-04-23 at 17:34.","The student, Perry Akrie, submitted this Thesis for approval on 2022-04-23 at 17:46.","This Thesis was approved for publication on 2022-04-27 at 14:18.","Submission original under an indefinite embargo labeled 'Open Access'.
