Method Evaluation And Field Sample Measurements For The Rate Of Movement Of The Oxidation Front In Saltstone (open access)

Method Evaluation And Field Sample Measurements For The Rate Of Movement Of The Oxidation Front In Saltstone

The objective of this work was to develop and evaluate a series of methods and validate their capability to measure differences in oxidized versus reduced saltstone. Validated methods were then applied to samples cured under field conditions to simulate Performance Assessment (PA) needs for the Saltstone Disposal Facility (SDF). Four analytical approaches were evaluated using laboratory-cured saltstone samples. These methods were X-ray absorption spectroscopy (XAS), diffuse reflectance spectroscopy (DRS), chemical redox indicators, and thin-section leaching methods. XAS and thin-section leaching methods were validated as viable methods for studying oxidation movement in saltstone. Each method used samples that were spiked with chromium (Cr) as a tracer for oxidation of the saltstone. The two methods were subsequently applied to field-cured samples containing chromium to characterize the oxidation state of chromium as a function of distance from the exposed air/cementitious material surface.

Plutonium and Americium Geochemistry at Hanford: A Site Wide Review (open access)

Plutonium and Americium Geochemistry at Hanford: A Site Wide Review

This report was produced to provide a systematic review of the state-of-knowledge of plutonium and americium geochemistry at the Hanford Site. The report integrates existing knowledge of the subsurface migration behavior of plutonium and americium at the Hanford Site with available information in the scientific literature regarding the geochemistry of plutonium and americium in systems that are environmentally relevant to the Hanford Site. As a part of the report, key research needs are identified and prioritized, with the ultimate goal of developing a science-based capability to quantitatively assess risk at sites contaminated with plutonium and americium at the Hanford Site and the impact of remediation technologies and closure strategies.

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012 (open access)

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012

The delicate balance among cellular pathways that control mutagenic changes in DNA will be the focus of the 2012 Mutagenesis Gordon Research Conference. Mutagenesis is essential for evolution, while genetic stability maintains cellular functions in all organisms from microbes to metazoans. Different systems handle DNA lesions at various times of the cell cycle and in different places within the nucleus, and inappropriate actions can lead to mutations. While mutation in humans is closely linked to disease, notably cancers, mutational systems can also be beneficial. The conference will highlight topics of beneficial mutagenesis, including full establishment of the immune system, cell survival mechanisms, and evolution and adaptation in microbial systems. Equal prominence will be given to detrimental mutation processes, especially those involved in driving cancer, neurological diseases, premature aging, and other threats to human health. Provisional session titles include Branching Pathways in Mutagenesis; Oxidative Stress and Endogenous DNA Damage; DNA Maintenance Pathways; Recombination, Good and Bad; Problematic DNA Structures; Localized Mutagenesis; Hypermutation in the Microbial World; and Mutation and Disease.

EFFECT OF CHLORIDE AND SULFATE CONCENTRATION ON PROBABLITY BASED CORROSION CONTROL FOR LIQUID WASTE TANKS- PART IV (open access)

EFFECT OF CHLORIDE AND SULFATE CONCENTRATION ON PROBABLITY BASED CORROSION CONTROL FOR LIQUID WASTE TANKS- PART IV

A series of cyclic potentiodynamic polarization tests was performed on samples of A537 carbon steel in support of a probability-based approach to evaluate the effect of chloride and sulfate on corrosion susceptibility. Testing solutions were chosen to build off previous experimental results from FY07, FY08, FY09 and FY10 to systemically evaluate the influence of the secondary aggressive species, chloride, and sulfate. The FY11 results suggest that evaluating the combined effect of all aggressive species, nitrate, chloride, and sulfate, provides a consistent response for determining corrosion susceptibility. The results of this work emphasize the importance for not only nitrate concentration limits, but also chloride and sulfate concentration limits as well.
