| Description/ Abstract |
The DOE is currently conducting cleanup activities at its nuclear weapons development sites, many of which have accumulated plutonium in soils for 50 years. To properly control Pu migration in soils within Federal sites and onto public lands, better evaluate the public risk, and design effective remediation strategies, a fundamental understanding of Pu speciation, transport, and release mechanisms is needed. Key scientific goals include: determine Pu concentrations and speciation at a contaminated DOE site; study the formation, stability, and structural and spectroscopic features of environmentally relevant Pu (III, IV, and V) species; determine the mechanism of interaction between Pu and Mn/Fe minerals and the potential release of Pu via redox cycling; and model the environmental behavior of plutonium. This report summarizes work after seven months of a three-year project. In the first year of this project the authors are focusing on the origin, speciation, and mobility of plutonium at the Rocky Flats Environmental Test Site (RFETS). |
