A letter report issued by the Government Accountability Office with an abstract that begins "Since enactment of the Water Resources Development Act of 2007, 49 project studies have undergone peer review but it is unclear how many were performed in response to section 2034 requirements because the Army Corps of Engineers (Corps) does not make specific determinations or track if a peer review is being conducted under section 2034. In February 2011, in response to section 2034, the Corps submitted its initial report to Congress summarizing its implementation of the peer review process. In its report, however, the Corps did not distinguish which studies had been selected for peer review in accordance with section 2034 and therefore, did not provide Congress information that would help decision makers evaluate the requirements of section 2034 at the end of the trial period."

A letter report issued by the Government Accountability Office with an abstract that begins "Interest has re-emerged in developing oil and gas in the nation's offshore areas, such as the North Aleutian Basin. Located on the outer continental shelf (OCS) where the Aleutian Islands meet the Alaskan mainland around Bristol Bay, the basin may contain sizable oil and gas deposits, although the area's environmental and cultural sensitivity has made oil and gas development in the area controversial. The Alaska OCS Region within the Department of the Interior's Minerals Management Service (MMS) oversees oil and gas development in this offshore area. GAO was asked to examine issues related to oil and gas development in the North Aleutian Basin. This report (1) describes the basin's estimated quantities of oil and gas and needed infrastructure; (2) identifies steps MMS is to take to meet federal requirements for oil and gas development; and (3) identifies challenges, if any, MMS faces in meeting these requirements in its Alaska OCS Region. GAO analyzed laws and documents and interviewed representatives from MMS, other federal agencies, state agencies, industry, and other stakeholders."

A letter report issued by the Government Accountability Office with an abstract that begins "While repayments, dividends, and interest from institutions participating in the Capital Purchase Program (CPP) have exceeded the program’s original investment disbursements, the number of missed payments has increased over the life of the program. As of January 31, 2012, the Department of the Treasury (Treasury) had received $211.5 billion from its CPP investments, exceeding the $204.9 billion it had disbursed. Of that amount, $16.7 billion remains outstanding, and most of these investments were concentrated in a relatively small number of institutions. In particular, as of January 31, 2012, 25 institutions accounted for $11.2 billion, or 67 percent, of outstanding investments. As of November 30, 2011, Treasury estimated that CPP would have a lifetime income of $13.5 billion after all institutions exited the program. As of January 31, 2012, 341 institutions had exited CPP, almost half by repaying CPP with funds from other federal programs. Institutions continue to exit CPP, but the number of institutions missing scheduled dividend or interest payments has increased. For example, as of November 30, 2011, the number of institutions that had missed their quarterly payments rose to 158, a marked increase from …

The Department of Homeland Security (DHS) has statutory authority to regulate chemical facilities for security purposes. The 112th Congress extended this authority through March 18, 2011. Debate continues in Congress over whether to let this extension expire or continue funding the authority. This report provides a brief overview of the existing statutory authority and the regulation implementing this authority. It describes several policy issues raised in previous debates regarding chemical facility security and identifies policy options for congressional consideration. Finally, legislation in the 112th Congress is discussed.

The PET radionuclides, 18F and 11C consist of very high radiation to mass amounts and should be easily adapted to new technologies such as “chip chemistry” with nanofluidics. However, environmental contamination with nonradioactive fluorine, carbon and other trace contaminants add sufficient mass, micrograms to milligrams, to prevent adapting PET radiochemistry to the nanochip technologies. In addition, the large volumes of material required for beam irradiation make it necessary to also remove the 18F and 11C from their chemical matrices. These steps add contaminants. The work described in this report was a systematic investigation of sources of these contaminants and methods to reduce these contaminants and the reaction volumes for radiochemical synthesis. Several methods were found to lower the contaminants and matrices to within a factor of 2 to 100 of those needed to fully implement chip technology but further improvements are needed.

CHPRC D&D Projects is adding three filtration system on two 1-ft concrete pads adjacent to the north side of existing KW Basin building. This analysis is prepared to provide qualitative assessment based on the review of design information available for 105KW basin substructure. In the proposed heating, ventilation and air conditioning (HVAC) filtration pad designs a 2 ft gap will be maintained between the pads and the north end of the existing 1 05KW -Basin building. Filtration Skids No.2 and No.3 share one pad. It is conservative to evaluate the No.2 and No.3 skid pad for the wall assessment. Figure 1 shows the plan layout of the 105KW basin site and the location of the pads for the filtration system or HVAC skids. Figure 2 shows the cross-section elevation view of the pad. The concrete pad Drawing H-1-91482 directs the replacement of the existing 8-inch concrete pad with two new 1-ft think pads. The existing 8-inch pad is separated from the 105KW basin superstructure by an expansion joint of only half an inch. The concrete pad Drawing H-1-91482 shows the gap between the new proposed pads and the north wall and any overflow pits and sumps is 2-ft. Following analysis …

The F-Area Tank Farm (FTF) Performance Assessment (PA) utilizes waste speciation in the waste release model used in the FTF fate and transport modeling. The waste release modeling associated with the residual plutonium in Tank 18 has been identified as a primary contributor to the Tank 18 dose uncertainty. In order to reduce the uncertainty related to plutonium in Tank 18, a better understanding of the plutonium speciation in the Tank 18 waste (including the oxidation state and stoichiometry) is desired. Savannah River National Laboratory (SRNL) utilized Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) to analyze Tank 18 samples to provide information on the speciation of plutonium in the waste material. XRD analysis of the Tank 18 samples did not identify any plutonium mineral phases in the samples. These indicates the crystalline mineral phases of plutonium are below the detection limits of the XRD method or that the plutonium phase(s) lack long range order and are present as amorphous or microcrystalline solids. SEM analysis of the Tank 18 samples did locate particles containing plutonium. The plutonium was found as small particles, usually <1 {micro}m but ranging up to several micrometers in diameter, associated with particles of an iron matrix …

Sellafield Ltd (United Kingdom) has requested technical support from the Savannah River National Laboratory (SRNL) to characterize a series of uranium-bearing, mixed alkali borosilicate glasses [WFO (2010)]. The specific glasses to be characterized are based on different blends of Magnox (WRW17 simulant) and Butex (or HASTs 1 and 2) waste types as well as different incorporation rates (or waste loadings) of each blend. Specific Magnox:Butex blend ratios of interest include: 75:25, 60:40, and 50:50. Each of these waste blend ratios will be mixed with a base glass additive composition targeting waste loadings (WLs) of 25, 28, and 32% which will result in nine different glasses. The nine glasses are to be fabricated and physically characterized to provide Sellafield Ltd with the technical data to evaluate the impacts of various Magnox:Butex blend ratios and WLs on key glass properties of interest. It should be noted that the use of 'acceptable' in the Work for Other (WFO) was linked to the results of a durability test (more specifically the Soxhlet leach test). Other processing (e.g., viscosity ({eta}), liquidus temperature (T{sub L})) or product performance (e.g., Product Consistency Test (PCT) results - in addition to the Soxhlet leach test) property constraints were not …
