242-16H 2H EVAPORATOR POT SAMPLING FINAL REPORT
Due to the materials that are processed through 2H Evaporator, scale is constantly being deposited on the surfaces of the evaporator pot. In order to meet the requirements of the Nuclear Criticality Safety Analysis/Evaluation (NCSA/NCSE) for 2H Evaporator, inspections of the pot are performed to determine the extent of scaling. Once the volume of scale reaches a certain threshold, the pot must be chemically cleaned to remove the scale. Prior to cleaning the pot, samples of the scale are obtained to determine the concentration of uranium and plutonium and also to provide information to assist with pot cleaning. Savannah River National Laboratory (SRNL) was requested by Liquid Waste Organization (LWO) Engineering to obtain these samples from two locations within the evaporator. Past experience has proven the difficulty of successfully obtaining solids samples from the 2H Evaporator pot. To mitigate this risk, a total of four samplers were designed and fabricated to ensure that two samples could be obtained. Samples had previously been obtained from the cone surface directly below the vertical access riser using a custom scraping tool. This tool was fabricated and deployed successfully. A second scraper was designed to obtain sample from the nearby vertical thermowell and a …

2010 Census: Plans for Decennial Census Operations and Technology Have Progressed, But Much Uncertainty Remains
Testimony issued by the Government Accountability Office with an abstract that begins "On April 3, 2008, the Secretary of Commerce announced significant changes to how the Census Bureau (Bureau) would conduct nonresponse follow-up, its largest field operation, in which census workers interview households that do not return initial census forms for the 2010 decennial census, and to its Field Data Collection Automation (FDCA) contract. The Bureau has since issued a redesigned plan to conduct a paper-based follow-up operation, an integrated 2010 Census project schedule, and is working on revising the FDCA contract. These are major changes late in the decennial census cycle. This testimony discusses (1) the Bureau's plans for conducting a paper-based nonresponse follow-up operation, (2) management of the FDCA contract and its latest cost estimates, and (3) the status of the Bureau's integrated 2010 project schedule. This testimony is based on past work, recent interviews with Bureau officials, and a review of redesign documents."

2010 IRON-SULFUR ENZYMES GORDON RESEARCH CONFERENCE, JUNE 6-11, 2010
Iron-sulfur (FeS) centers are essential for biology and inspirational in chemistry. These protein cofactors are broadly defined as active sites in which Fe is coordinated by S-donor ligands, often in combination with extra non-protein components, for example, additional metal atoms such as Mo and Ni, and soft ligands such as CN{sup -} and CO. Iron-sulfur centers are inherently air sensitive: they are found in essentially all organisms and it is possible that they were integral components of the earliest forms of life, well before oxygen (O{sub 2}) appeared. Proteins containing FeS cofactors perform a variety of biological functions ranging across electron transfer, acid-base catalysis, and sensing where they are agents for cell regulation through transcription (DNA) or translation (RNA). They are redox catalysts for radical-based reactions and the activation of H{sub 2}, N{sub 2} and CO{sub 2}, processes that offer scientific and economic challenges for industry. Iron-sulfur centers provide the focus for fundamental investigations of chemical bonding, spectroscopy and paramagnetism, and their functions have numerous implications for health and medicine and applications for technology, including renewable energy. The 2010 Iron-Sulfur Enzymes GRC will bring together researchers from different disciplines for in-depth discussions and presentations of the latest developments. There will …

An Active Region Model for Capturing Fractal Flow Patterns inUnsaturated Soils: Model Development
Preferential flow commonly observed in unsaturated soils allows rapid movement of solute from the soil surface or vadose zone to the groundwater, bypassing a significant volume of unsaturated soil and increasing the risk of groundwater contamination. A variety of evidence indicates that complex preferential patterns observed from fields are fractals. In this study, we developed a relatively simple active region model to incorporate the fractal flow pattern into the continuum approach. In the model, the flow domain is divided into active and inactive regions. Flow occurs preferentially in the active region (characterized by fractals), and inactive region is simply bypassed. A new constitutive relationship (the portion of the active region as a function of saturation) was derived. The validity of the proposed model is demonstrated by the consistency between field observations and the new constitutive relationship.

Advanced waste forms research and development. Annual report
Thermogravimetric analysis on cesium aluminosilicates was performed. Pollucite, CsAlSi/sub 2/O/sub 6/, appears to have more than adequate thermal stability for Cs fixation in supercalcine. The possibility of leaving Ru as RuO/sub 2/ during supercalcine crystallization is being assessed. The apatite solid solution (A/sub ss/) phases used in supercalcine phase formation models have been easily prepared as pure phases. Use of Ca instead of Sr as an alkaline earth additive yields a more stable A/sub ss/ phase. Weight ratios have been optimized for two firing temperatures in terms of soxhlet leachability. However, this is not the preferred approach to supercalcine consolidation. The phase formation models developed for PW-4b-type wastes were routinely applied to PW-7, in spite of several significant composition differences in the latter. Uranium oxide remains as a fluorite structure oxide after supercalcine crystallization, but it does seem to have incorporated either or both CeO/sub 2/ or ZrO/sub 2/. Characterization of this F/sub ss/ phase will require further study. Based on observations during several complex compatibility studies, it appears that good overall thermal stability at as high as 1200/sup 0/C might be attainable for nepheline based supercalcine formulations. A thorough literature review of the oxide crystal chemistry of Te has …
