2020 Census: Progress Report on the Census Bureau's Efforts to Contain Enumeration Costs (open access)

2020 Census: Progress Report on the Census Bureau's Efforts to Contain Enumeration Costs

Testimony issued by the Government Accountability Office with an abstract that begins "In preparing for the 2020 Census, the U.S. Census Bureau (Bureau) has launched several initiatives aimed at organizational transformation, some of which show particular promise. For example, the Bureau is attempting to develop Bureau-wide, or "enterprise," standards, guidance, or tools in areas such as risk management and information technology (IT) investment management to reduce duplicative efforts across the Bureau. Although the Bureau has made progress in these and other areas, if the Bureau is to transform itself to better control costs and deliver an accurate national headcount in 2020, several areas will require continued oversight: cost estimation, integrated long-term planning, and stakeholder involvement. For example, while the Bureau has made progress with long-term planning by implementing some elements of GAO's recommendation that it develop a road map for 2020 planning, it still needs to pull together remaining planning elements, such as milestones for decisions and estimates of cost, into its roadmap."

Modernizing the Nuclear Security Enterprise: Observations on NNSA's Options for Meeting Its Plutonium Research Needs (open access)

Modernizing the Nuclear Security Enterprise: Observations on NNSA's Options for Meeting Its Plutonium Research Needs

A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration's (NNSA) Los Alamos National Laboratory's (LANL) April 2012 study (1) identified general options for meeting the plutonium research needs of NNSA--a separately organized agency within the Department of Energy (DOE)--during the several-year gap created by the deferral of the Chemistry and Metallurgy Research Replacement (CMRR) nuclear facility and (2) included limited information on costs and health risks. The study noted that the level of plutonium research necessary to support the nuclear weapons life extension programs is affected by the planned schedule of the life extension programs, the number of pits that will be needed under the programs, and the number of pits that will need to be manufactured versus re-used, all of which have uncertainties. According to the April 2012 study, one option for meeting NNSA's plutonium research needs is to relocate analytical chemistry and materials characterization capabilities among facilities at LANL, which will require upgrades costing roughly $480 million to $820 million. A second option is to move capabilities to existing facilities at other sites. The study concluded that no single site could provide all the capabilities that might be …

Cargo Tank Trucks: Improved Incident Data and Regulatory Analysis Would Better Inform Decisions about Safety Risks (open access)

Cargo Tank Trucks: Improved Incident Data and Regulatory Analysis Would Better Inform Decisions about Safety Risks

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration's (PHMSA) incident data cannot be used to reliably identify risks from incidents involving collisions with and spills from tank trucks' bottom lines ("wetlines") because the incidents are not specifically identified in PHMSA's database and the data contain inaccuracies. PHMSA requires carriers to report hazardous material incidents, but the reporting form does not specifically capture wetline incidents. PHMSA officials identify wetline incidents through a resource-intensive process of reviewing carrier-reported incident narratives and other information. However, GAO found that the narratives do not always clearly indicate whether an incident is wetline related and that information about the consequences of incidents, including fatalities, is not always accurate. PHMSA has made efforts to improve its data, such as adding quality checks, but this has not affected how wetline incidents are reported, and inaccuracies remain."

Delphi Pensions: Key Events Leading to Plan Terminations (open access)

Delphi Pensions: Key Events Leading to Plan Terminations

Testimony issued by the Government Accountability Office with an abstract that begins "The termination of the six defined benefit plans that were sponsored by the Delphi Corporation (Delphi) and the provision of benefit protections to some Delphi employees, but not others, culminated from a complex series of events involving Delphi, the General Motors Corporation (GM), various unions, the U.S. Department of the Treasury (Treasury), and the Pension Benefit Guaranty Corporation (PBGC). When Delphi spun off from GM in 1999, three unions secured an agreement that GM would provide a retirement benefit supplement (referred to as "top-ups") for their members should their pension plans be frozen or terminated and they were to suffer a resulting loss in pension benefits. These three unions were: (1) the International Union, United Automobile, Aerospace, and Agricultural Implement Workers of America (UAW); (2) the International Union of Electronic, Electrical, Salaried, Machine and Furniture Workers, AFL-CIO (IUE); and (3) the United Steelworkers of America (USWA). No other Delphi employees had a similar agreement to receive a top-up, including salaried workers and hourly workers belonging to other unions. Over the course of events that unfolded over the next decade, the agreements with these three unions ultimately were preserved …

Unemployment Insurance Information Technology: States Face Challenges in Modernization Efforts

Testimony issued by the Government Accountability Office with an abstract that begins "As GAO reported in September 2012, nine selected states had made varying degrees of progress in modernizing the information technology (IT) systems supporting their unemployment insurance (UI) programs. Specifically, the states' modernization efforts were at various stages--three were in early phases of defining business needs and requirements, two were in the process of building systems based on identified requirements, two were in a "mixed" phase of having a system that was partly operational and partly in development, and two had systems that were completely operational. The enhancements provided by these systems included supporting web-based technologies with more modern databases and replacing outdated programming languages, among others."

Polar Weather Satellites: NOAA Identified Ways to Mitigate Data Gaps, but Contingency Plans and Schedules Require Further Attention (open access)

Polar Weather Satellites: NOAA Identified Ways to Mitigate Data Gaps, but Contingency Plans and Schedules Require Further Attention

A letter report issued by the Government Accountability Office with an abstract that begins "The National Oceanic and Atmospheric Administration (NOAA) has made noteworthy progress on the Joint Polar Satellite System (JPSS) program by delivering data from its first satellite--the Suomi National Polar-orbiting Partnership (S-NPP)--to weather forecasters, completing significant instrument development for the next satellite (called JPSS-1), and reducing the program's life cycle cost estimate from $12.9 billion to $11.3 billion by refocusing on weather products. However, key challenges remain. Specifically, S-NPP has not yet achieved full operational capability because the program is behind schedule in validating the readiness of satellite products. Also, the program does not track whether key users are using its products or if the products meet the users' needs. In addition, issues with the JPSS ground system schedules have delayed the delivery of key system capabilities. Until the program addresses these challenges, it may continue to experience delays in delivering actionable S-NPP data to system users and in meeting JPSS-1 development schedules."

Nevada National Security Site Environmental Report 2012 Attachment A: Site Description (open access)

Nevada National Security Site Environmental Report 2012 Attachment A: Site Description

This attachment expands on the general description of the Nevada National Security Site (NNSS) presented in the Introduction to the Nevada National Security Site Environmental Report 2012 (National Security Technologies, LLC [NSTec], 2013). Included are subsections that summarize the site’s geological, hydrological, climatological, and ecological setting and the cultural resources of the NNSS. The subsections are meant to aid the reader in understanding the complex physical and biological environment of the NNSS. An adequate knowledge of the site’s environment is necessary to assess the environmental impacts of new projects, design and implement environmental monitoring activities for current site operations, and assess the impacts of site operations on the public residing in the vicinity of the NNSS. The NNSS environment contributes to several key features of the site that afford protection to the inhabitants of adjacent areas from potential exposure to radioactivity or other contaminants resulting from NNSS operations. These key features include the general remote location of the NNSS, restricted access, extended wind transport times, the great depths to slow-moving groundwater, little or no surface water, and low population density. This attachment complements the annual summary of monitoring program activities and dose assessments presented in the main body of this …

Identification and Characterization of Soluble Factors Involved in Delayed Effects of Low Dose Radiation. Final report (open access)

Identification and Characterization of Soluble Factors Involved in Delayed Effects of Low Dose Radiation. Final report

This is a 'glue grant' that was part of a DOE Low Dose project entitled 'Identification and Characterization of Soluble Factors Involved in Delayed Effects of Low Dose Radiation'. This collaborative program has involved Drs. David L. Springer from Pacific Northwest National Laboratory (PNNL), John H. Miller from Washington State University, Tri-cities (WSU) and William F. Morgan then from the University of Maryland, Baltimore (UMB). In July 2008, Dr. Morgan moved to PNNL and Dr. Janet E. Baulch became PI for this project at University of Maryland. In November of 2008, a one year extension with no new funds was requested to complete the proteomic analyses. The project stemmed from studies in the Morgan laboratory demonstrating that genomically unstable cells secret a soluble factor or factors into the culture medium, that cause cytogenetic aberrations and apoptosis in normal parental GM10115 cells. The purpose of this project was to identify the death inducing effect (DIE) factor or factors, estimate their relative abundance, identify the cell signaling pathways involved and finally recapitulate DIE in normal cells by exogenous manipulation of putative DIE factors in culture medium. As reported in detail in the previous progress report, analysis of culture medium from the parental …

Evaluating the Contribution of Climate Forcing and Forest Dynamics to Accelerating Carbon Sequestration by Forest Ecosystems in the Northeastern U.S. (open access)

Evaluating the Contribution of Climate Forcing and Forest Dynamics to Accelerating Carbon Sequestration by Forest Ecosystems in the Northeastern U.S.

We used 10 Hz eddy flux signals and 0.2 Hz incident radiation (global shortwave and PAR) records from Harvard Forest (Massachusetts) and Tapajos National Forest (Brazil) to establish empirical relationships among directly measured cloud type and cover percentage and corresponding PAR fluctuations and its diffuse fraction. In future work such a cloud characterization will be related to water and light use efficiency estimates for each of these ecosystems. We developed empirical relationships to link sky cover type and fraction (measured with the ceilometer) to incident direct and diffuse PAR. We developed a methodology for constructing synthetic incident solar radiation time series based on operational reports of sky cover and cloud type from National Weather Service METAR reports. The aim of this work is to document the temporal and spectral properties radiation incident on the canopy, as a first step toward developing a sky-type parameterization for the net carbon uptake models.

REDUCTIONS WITHOUT REGRET: AVOIDING WRONG TURNS, ROACH MOTELS, AND BOX CANYONS (open access)

REDUCTIONS WITHOUT REGRET: AVOIDING WRONG TURNS, ROACH MOTELS, AND BOX CANYONS

This is the third of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as some closing thoughts for the future. In this paper, we provide one example each of our judgments on what constitutes a box canyon, a roach motel, and a wrong turn: � Wrong Turn: The Reliable Replacement Warhead � Roach Motel: SRAM T vs the B61 � A Possible Box Canyon: A Low-Yield Version of the W76 SLBM Warhead Recognizing that new nuclear missions or weapons are not demanded by current circumstances � a development path that yields future capabilities similar to those of today, which are adequate if not always ideal, and a broader national-security strategy that supports nonproliferation and arms …

Analysis Of 2H-Evaporator Scale Wall [HTF-13-82] And Pot Bottom [HTF-13-77] Samples (open access)

Analysis Of 2H-Evaporator Scale Wall [HTF-13-82] And Pot Bottom [HTF-13-77] Samples

Savannah River Remediation (SRR) is planning to remove a buildup of sodium aluminosilicate scale from the 2H-evaporator pot by loading and soaking the pot with heated 1.5 M nitric acid solution. Sampling and analysis of the scale material has been performed so that uranium and plutonium isotopic analysis can be input into a Nuclear Criticality Safety Assessment (NCSA) for scale removal by chemical cleaning. Historically, since the operation of the Defense Waste Processing Facility (DWPF), silicon in the DWPF recycle stream combines with aluminum in the typical tank farm supernate to form sodium aluminosilicate scale mineral deposits in the 2H-evaporator pot and gravity drain line. The 2H-evaporator scale samples analyzed by Savannah River National Laboratory (SRNL) came from two different locations within the evaporator pot; the bottom cone sections of the 2H-evaporator pot [Sample HTF-13-77] and the wall 2H-evaporator [sample HTF-13-82]. X-ray diffraction analysis (XRD) confirmed that both the 2H-evaporator pot scale and the wall samples consist of nitrated cancrinite (a crystalline sodium aluminosilicate solid) and clarkeite (a uranium oxyhydroxide mineral). On ''as received'' basis, the bottom pot section scale sample contained an average of 2.59E+00 {+-} 1.40E-01 wt % total uranium with a U-235 enrichment of 6.12E-01 {+-} 1.48E-02 …
