Federal Land Management: Observations on a Possible Move of the Forest Service into the Department of the Interior (open access)

Federal Land Management: Observations on a Possible Move of the Forest Service into the Department of the Interior

A letter report issued by the Government Accountability Office with an abstract that begins "Growing ecological challenges ranging from wildland fires to climate change have revived interest in moving the Department of Agriculture's (USDA) Forest Service into the Department of the Interior (Interior). The Forest Service manages almost a quarter of the nation's lands but is the only major land management agency outside Interior. GAO was asked to report on the potential effects of moving the Forest Service into Interior and creating a new bureau equal to Interior's other bureaus, such as the Bureau of Land Management (BLM). GAO was also asked to identify factors that should be considered if such a move were legislated and management practices that could facilitate a move. GAO analyzed five historical proposals to reorganize federal land management agencies; interviewed USDA, Interior, and other officials and outside experts; and studied joint Forest Service- BLM programs to assess efforts to integrate the agencies' work."

Defense Acquisitions: Assessments Needed to Address V-22 Aircraft Operational and Cost Concerns to Define Future Investments (open access)

Defense Acquisitions: Assessments Needed to Address V-22 Aircraft Operational and Cost Concerns to Define Future Investments

A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1980s, the V-22, developed to transport combat troops, supplies, and equipment for the U.S. Marine Corps and to support other services' operations, has experienced several fatal crashes, demonstrated various deficiencies, and faced virtual cancellation--much of which it has overcome. Although until recently deployed in Iraq and regarded favorably, it has not performed the full range of missions anticipated, and how well it can do so is in question. In view of concerns about the V-22 program, you asked us to determine if the V-22 will perform as promised, and if it will, at what cost. GAO reviewed (1) current MV-22 operations in Iraq; (2) strengths and deficiencies in terms of the capabilities expected of the V-22; and (3) past, current, and future costs. GAO reviewed a range of program documents and data, interviewed program officials, operators and others; and observed MV-22 operations in Iraq and shipboard."

Public Housing: HUD's Oversight of Housing Agencies Should Focus More on Inappropriate Use of Program Funds (open access)

Public Housing: HUD's Oversight of Housing Agencies Should Focus More on Inappropriate Use of Program Funds

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Housing and Urban Development (HUD) provided over $6.7 billion in fiscal year 2008 to housing agencies to operate, modernize, and develop about 1.2 million public housing units. It is important that HUD exercise sufficient oversight of housing agencies to help ensure that public housing funds are being used as intended and properly managed. In this report, GAO examines HUD's oversight processes for detecting housing agencies at risk of inappropriate use and mismanagement of public housing funds. GAO analyzed HUD financial data on about 3,300 housing agencies, compared HUD's oversight policies with program and agency objectives, and interviewed agency officials."

National Institutes of Health: Completion of Comprehensive Risk Management Program Essential to Effective Oversight (open access)

National Institutes of Health: Completion of Comprehensive Risk Management Program Essential to Effective Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "The National Institutes of Health (NIH), an agency of the Department of Health and Human Services (HHS), is the primary federal agency for supporting medical research. The Office of the Director (OD) is the central NIH office responsible for setting policy and overseeing NIH's 27 institutes and centers (IC). Allegations involving one institute raised questions about areas of oversight by the OD. In light of these questions, GAO examined (1) how NIH makes extramural research funding decisions and OD monitoring of this process, (2) the design of selected internal controls over NIH's travel and personnel appointment processes, and (3) the design of NIH's new risk management program and the program it is replacing. To address these objectives, GAO reviewed relevant NIH policies, procedures, and supporting documentation. GAO also selected 3 institutes that varied in size for in-depth reviews."

Business Systems Modernization: Internal Revenue Service's Fiscal Year 2009 Expenditure Plan

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) Business Systems Modernization (BSM) program is a multi-billion-dollar, high-risk, highly complex effort that involves the development and delivery of a number of modernized systems that are intended to replace the agency's aging business and tax processing systems. As required, IRS submitted its fiscal year 2009 expenditure plan in August 2008 to the congressional appropriations committees, requesting $222 million from the BSM account. GAO's objectives in reviewing the expenditure plan were to (1) determine whether it satisfies the applicable legislative conditions, (2) determine IRS's progress in implementing prior expenditure plan review recommendations, and (3) provide additional observations about the plan and the BSM program. To accomplish the objectives, GAO analyzed the plan, reviewed related documentation, and interviewed IRS officials."

Ionic Liquids for Utilization of Waste Heat from Distributed Power Generation Systems (open access)

Ionic Liquids for Utilization of Waste Heat from Distributed Power Generation Systems

The objective of this research project was the development of ionic liquids to capture and utilize waste heat from distributed power generation systems. Ionic Liquids (ILs) are organic salts that are liquid at room temperature and they have the potential to make fundamental and far-reaching changes in the way we use energy. In particular, the focus of this project was fundamental research on the potential use of IL/CO2 mixtures in absorption-refrigeration systems. Such systems can provide cooling by utilizing waste heat from various sources, including distributed power generation. The basic objectives of the research were to design and synthesize ILs appropriate for the task, to measure and model thermophysical properties and phase behavior of ILs and IL/CO2 mixtures, and to model the performance of IL/CO2 absorption-refrigeration systems.

Sludge Batch 5 Slurry Fed Melt Rate Furnace Test with Frits 418 and 550 (open access)

Sludge Batch 5 Slurry Fed Melt Rate Furnace Test with Frits 418 and 550

Based on Melt Rate Furnace (MRF) testing for the Sludge Batch 5 (SB5) projected composition and assessments of the potential frits with reasonable operating windows, the Savannah River National Laboratory (SRNL) recommended Slurry Fed Melt Rate Furnace (SMRF) testing with Frits 418 and 550. DWPF is currently using Frit 418 with SB5 based on SRNL's recommendation due to its ability to accommodate significant sodium variation in the sludge composition. However, experience with high boron containing frits in DWPF indicated a potential advantage for Frit 550 might exist. Therefore, SRNL performed SMRF testing to assess Frit 550's potential advantages. The results of SMRF testing with SB5 simulant indicate that there is no appreciable difference in melt rate between Frit 418 and Frit 550 at a targeted 34 weight % waste loading. Both batches exhibited comparable behavior when delivered through the feed tube by the peristaltic pump. Limited observation of the cold cap during both runs showed no indication of major cold cap mounding. MRF testing, performed after the SMRF runs due to time constraints, with the same two Slurry Mix Evaporator (SME) dried products led to the same conclusion. Although visual observations of the cross-sectioned MRF beakers indicated differences in the …

Tank 26 Evaporator Feed Pump Transfer Analysis (open access)

Tank 26 Evaporator Feed Pump Transfer Analysis

The transfer of liquid salt solution from Tank 26 to an evaporator is to be accomplished by activating the evaporator feed pump, located approximately 72 inches above the sludge layer, while simultaneously turning on the downcomer. Previously, activation of the evaporator feed pump was an isolated event without any other components running at the same time. An analysis of the dissolved solution transfer has been performed using computational fluid dynamics methods to determine the amount of entrained sludge solids pumped out of the tank to the evaporator with the downcomer turned on. The analysis results showed that, for the maximum and minimum supernate levels in Tank 26 (252.5 and 72 inches above the sludge layer, respectively), the evaporator feed pump will entrain between 0.03 and 0.1 wt% sludge undissolved solids weight fraction into the eductor, respectively, and therefore are an order of magnitude less than the 1.0 wt% undissolved solids loading criteria to feed the evaporator. Lower tank liquid levels, with respect to the sludge layer, result in higher amounts of sludge entrainment due to the increased velocity of the plunging jets from the downcomer and evaporator feed pump bypass as well as decreased dissipation depth. Revision 1 clarifies the …

NERI FINAL TECHNICAL REPORT, DE-FC07-O5ID14647, OPTIMIZATION OF OXIDE COMPOUNDS FOR ADVANCED INERT MATRIX MATERIALS (open access)

NERI FINAL TECHNICAL REPORT, DE-FC07-O5ID14647, OPTIMIZATION OF OXIDE COMPOUNDS FOR ADVANCED INERT MATRIX MATERIALS

In order to reduce the current excesses of plutonium (both weapon grade and reactor grade) and other transuranium elements, a concept of inert matrix fuel (IMF) has been proposed for an uranium free transmutation of fissile actinides which excludes continuous uranium-plutonium conversion in thermal reactors and advanced systems. Magnesium oxide (MgO) is a promising candidate for inert matrix (IM) materials due to its high melting point (2827 C), high thermal conductivity (13 W/K {center_dot} m at 1000 C), good neutronic properties, and irradiation stability However, MgO reacts with water and hydrates easily, which prevents it from being used in light water reactors (LWRs) as an IM. To improve the hydration resistance of MgO-based inert matrix materials, Medvedev and coworkers have recently investigated the introduction of a secondary phase that acts as a hydration barrier. An MgO-ZrO{sub 2} composite was specifically studied and the results showed that the composite exhibited improved hydration resistance than pure MgO. However, ZrO{sub 2} is insoluble in most acids except HF, which is undesirable for fuel reprocessing. Moreover, the thermal conductivity of ZrO{sub 2} is low and typically less than 3 W {center_dot} m{sup -1} {center_dot} K{sup -1} at 1000 C. In search for an alternative …

Tracking the Sun: The Installed Cost of Photovoltaics in the U.S. from 1998-2007 (open access)

Tracking the Sun: The Installed Cost of Photovoltaics in the U.S. from 1998-2007

As installations of grid-connected solar photovoltaic (PV) systems have grown, so too has the desire to track the installed cost of these systems over time, by system characteristics, by system location, and by component. This report helps to fill this need by summarizing trends in the installed cost of grid-connected PV systems in the United States from 1998 through 2007. The report is based on an analysis of installed cost data from nearly 37,000 residential and non-residential PV systems, totaling 363 MW of capacity, and representing 76percent of all grid-connected PV capacity installed in the U.S. through 2007.

Final Report 200 MW L-Band Annular Beam Klystron for Accelerators (open access)

Final Report 200 MW L-Band Annular Beam Klystron for Accelerators

This program developed a 200 MW, 1.3 GHz, Annular Beam Klystron (ABK) for accelerator systems. An ABK provides lower impedance than a conventional klystron, making it possible to produce higher RF powers with lower voltages. With a higher power per unit, fewer klystrons would be required for a large accelerator. Lower voltage also simplifies and reduces the cost of the power supply system. Both features will significantly lower the cost of an RF system. This device operates at 475 kV. The klystron uses a magnetron injection gun producing 1100 A in one microsecond pulses. Power is extracted into fundamental rectangular waveguide through two output windows. The predicted gain is approximately 45 dB with estimated efficiency of 45%. The klystron was assembled, but no facility was available for testing. Consequently, no high power performance measurements are available. Because the assembled klystron is approximately 15 feet long, it was disassembled for storage. It can be reassembled should a use materialize.

Foam Transport in Porous Media - A Review (open access)

Foam Transport in Porous Media - A Review

Amendment solutions with or without surfactants have been used to remove contaminants from soil. However, it has drawbacks such that the amendment solution often mobilizes the plume, and its movement is controlled by gravity and preferential flow paths. Foam is an emulsion-like, two-phase system in which gas cells are dispersed in a liquid and separated by thin liquid films called lamellae. Potential advantages of using foams in sub-surface remediation include providing better control on the volume of fluids injected, uniformity of contact, and the ability to contain the migration of contaminant laden liquids. It is expected that foam can serve as a carrier of amendments for vadose zone remediation, e.g., at the Hanford Site. As part of the U.S. Department of Energy’s EM-20 program, a numerical simulation capability will be added to the Subsurface Transport Over Multiple Phases (STOMP) flow simulator. The primary purpose of this document is to review the modeling approaches of foam transport in porous media. However, as an aid to understanding the simulation approaches, some experiments under unsaturated conditions and the processes of foam transport are also reviewed. Foam may be formed when the surfactant concentration is above the critical micelle concentration. There are two main …

Energy Saving Glass Lamination via Selective Radio-Frequency Heating (open access)

Energy Saving Glass Lamination via Selective Radio-Frequency Heating

This Inventions and Innovations program supported the technical and commercial research and development needed to elevate Ceralink's energy saving process for flat glass lamination from bench scale to a self-supporting technology with significant potential for growth. Radio-frequency heating was any un-explored option for laminating glass prior to this program. With significant commercial success through time and energy savings in the wood, paper, and plastics industries, RF heating was found to have significant promise for the energy intensive glass lamination industry. A major technical goal of the program was to demonstrate RF lamination across a wide range of laminate sizes and materials. This was successfully accomplished, dispelling many skeptics' concerns about the abilities of the technology. Ceralink laminated panels up to 2 ft x 3 ft, with four sets processed simultaneously, in a 3 minute cycle. All major categories of interlayer materials were found to work with RF lamination. In addition to laminating glass, other materials including photovoltaic silicon solar cells, light emitting diodes, metallized glass, plastics (acrylic and polycarbonate), and ceramics (alumina) were found compatible with the RF process. This opens up a wide range of commercial opportunities beyond the initially targeted automotive industry. The dramatic energy savings reported for …

Tank Space Options Report (open access)

Tank Space Options Report

Since this report was originally issued in 2001, several options proposed for increasing double-shell tank (DST) storage space were implemented or are in the process of implementation. Changes to the single-shell tank (SST) waste retrieval schedule, completion of DST space saving options, and the DST space saving options in progress have delayed the projected shortfall of DST storage space from the 2007-2011 to the 2018-2025 timeframe (ORP-11242, River Protection Project System Plan). This report reevaluates options from Rev. 0 and includes evaluations of new options for alleviating projected restrictions on SST waste retrieval beginning in 2018 because of the lack of DST storage space.

DWPF GC FILTER ASSEMBLY SAMPLING AND ANALYSIS (open access)

DWPF GC FILTER ASSEMBLY SAMPLING AND ANALYSIS

On March 18, 2009 a Defense Waste Processing Facility (DWPF) GC Line Filter Assembly was received at the Savannah River National Laboratory (SRNL). This filter assembly was removed from operation following the completion of Sludge Batch 4 processing in the DWPF. Work on this sample was requested in a Technical Assistance Request. This document reports the pictures, observations, samples collected, and analytical results for the assembly. The assembly arrived at SRNL separated into its three component filters: high efficiency particulate air (HEPA)-1, HEPA-2, and a high efficiency mist evaporator (HEME). Each stage of the assembly's media was sampled and examined visually and by scanning electron microscopy (SEM). Solids built up in the filter housing following the first stage HEME, were dissolved in dilute nitric acid and analyzed by ICP-AES and the undissolved white solids were analyzed by x-ray diffraction (XRD). The vast majority of the material in each of the three stages of the DWPF GC Line Filter Assembly appears to be contaminated with a Hg compound that is {approx}59 wt% Hg on a total solids basis. The Hg species was identified by XRD analysis to contain a mixture of Hg{sub 4}(OH)(NO{sub 3}){sub 3} and Hg{sub 10}(OH){sub 4}(NO{sub 3}){sub 6}. …

Paleontological overview of oil shale and tar sands areas in Colorado, Utah, and Wyoming. (open access)

Paleontological overview of oil shale and tar sands areas in Colorado, Utah, and Wyoming.

In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the ''Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005,'' Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. In addition, Congress declared that both research- and commercial-scale development of oil shale and tar sands should (1) be conducted in an environmentally sound manner using management practices that will minimize potential impacts, (2) occur with an emphasis on sustainability, and (3) benefit the United States while taking into account concerns of the affected states and communities. To support this declaration of policy, Congress directed the Secretary of the Interior to undertake a series of steps, several of which are directly related to the development of a commercial leasing program for oil shale and tar sands. One of these steps was the completion of a programmatic environmental impact statement (PEIS) to analyze the impacts of a commercial leasing program for oil shale and tar sands …

Separation of Highly Complex Mixtures by Two-Dimension Liquid Chromatography (open access)

Separation of Highly Complex Mixtures by Two-Dimension Liquid Chromatography

This report summarizes the progress made on the title project during the grant period. We developed a new classification of two-dimensional separations based on the observation that separations can be made in time or in space. Thus, two-dimensional separations can be made in time×time, space×space, space×time, or time×space. The two successive separations must use two different modes of chromatography that afford uncorrelated or weakly correlated patterns of retention factors for the components of the samples analyzed. Our attention was mainly focused on the separation of protein digests, particularly, on those of the digests of myoglobin and bovine serum albumin as model systems and extremely efficient temporal separations were developed. We also designed and constructed new instruments to carry out space×space separations (True Bidimensional Chromatography, HPLC2 or spacial separations) and time×space separations (a new hybrid combination of a temporal and a spacial separation that we designed).
