Technical-economic assessment of the production of methanol from biomass. Executive summary. Final research report (open access)

Technical-economic assessment of the production of methanol from biomass. Executive summary. Final research report

The results are presented of a comprehensive systems study which assessed the engineering and economic feasibilities of the production of methanol from biomass utilizing existing technology. The three major components of the biomass to methanol system assessed are the availability of biomass feedstocks, the thermochemical conversion of biomass to methanol fuels, and the distribution and markets for methanol fuels. The results of this study show that methanol fuel can be produced from biomass using commercially available technology in the near term, and could be produced economically in significant quantities in the mid-to-late 1980's when advanced technology is available.

An analysis of grazing incidence metal mirrors in a laser ICF reactor driver (open access)

An analysis of grazing incidence metal mirrors in a laser ICF reactor driver

Grazing incidence metal mirrors (GIMMs) are examined to replace dielectric mirrors for the final elements in a laser beam line for an inertial confinement fusion reactor. For a laser driver with a wavelength from 250 to 500 nm in a 10-ms pulse, irradiated mirrors made of Al, Al alloys, or Mg were found to have calculated laser damage limits of 0.3--2.3 J/cm{sup 2} of beam energy and neutron lifetime fluence limits of over 5 {times} 10{sup 20} 14 MeV n/cm{sup 2} when used at grazing incidence and operated at room temperature or at 77 K. A final focusing system including mirrors made of Al alloy 7475 at room temperature or at liquid nitrogen temperatures used with a driver which delivers 5 MJ of beam energy in 32 beams would require 32 mirrors of roughly 10 m{sup 2} each. This chapter includes calculations of damage limits for GIMMs and discusses critical issues relevant to the integrity and lifetime of such mirrors in a reactor environment. The reflectivities of various metals are calculated from measured optical constants at room temperature and at cryogenic temperatures for 250- to 500-nm light at both normal and grazing incidence. Then, for the mirrors in a representative …

DOE Site-Specific Threat Assessment (open access)

DOE Site-Specific Threat Assessment

A facility manager faced with the challenges of protecting a nuclear facility against potential threats must consider the likelihood and consequences of such threats, know the capabilities of the facility safeguards and security systems, and make informed decisions about the cost-effectivness of safeguards and security upgrades. To help meet these challenges, the San Francisco Operations Office of the Department of Energy, in conjunction with the Lawrence Livermore Laboratory, has developed a site-specific threat assessment approach and a quantitative model to improve the quality and consistency of site-specific threat assessment and resultant security upgrade decisions at sensitive Department of Energy facilities. 5 figs.

PRELIMINARY DESIGN OF A HYDROGEN-COOLED IN-PILE LOOP FOR THE EGCR (open access)

PRELIMINARY DESIGN OF A HYDROGEN-COOLED IN-PILE LOOP FOR THE EGCR

A discussion is presented concerning the preliminary design and hazards evaluation of a H-cooled in-pile experimental loop for operation in the large double-walled through-tube in the Experimental Gas-Cooled Reactor (EGCR) at Oak Ridge. This loop is designed to permit experimentation with full-scale fuel element configurations up to 8 in. OD, at inlet gas temperatures of 600 to 950 deg F at 300 psig, and experimental power levels up to 500 kw. The results of a preliminary hazards evaluation indicate that a loop of this type can be safely operated in the EGCR. The H flammability hazard is controlled by blanketing all H-filled pipes and components with a sufficient quantity of nonreactive gas, such as He or CO/ sup 2/, to produce a noncombustible mixture for all credible H- release situations.

ZrH-reactor-technology program. Progress report, April-June 1974

The report on the 2 kW(e) reactor-organic Rankine system was drafted. This report details the design parameters of a minimum weight, 2 kW(e) reactor-organic Rankine system. The system is designed for 5 years unattended life in space. The reactor produces 16.2 kW of thermal power with a NaK outlet temperature of 800/sup 0/F and a 200/sup 0/F ..delta..T. The reactor contains 19 fuel elements, 1.25'' in diameter by 10'' long, hydrided to an N/sub H/ of 6.35. The terrestrial applications effort was oriented towards the establishment of the feasibility of utilizing the zirconium hydride reactor technology in a subsea application for supplying electrical power to deep water, and other environmentally severe, oil well installations. The overall system concept is shown. The power system is composed of three basic modules (i.e., a reactor module, a generator module, and a heat rejection system) mounted on a barge. The barge is then towed to the installation site and submerged to mate with a previously installed seafloor foundation. An assembly/disassembly sequence was drafted detailing the steps required to assemble the reactor module and to disassemble it after 4 years of operations.

Department of Energy: Further Actions Are Needed to Improve DOE's Ability to Evaluate and Implement the Loan Guarantee Program

A letter report issued by the Government Accountability Office with an abstract that begins "Since the Department of Energy's (DOE) loan guarantee program (LGP) for innovative energy projects was established in Title XVII of the Energy Policy Act of 2005, its scope has expanded both in the types of projects it can support and in the amount of loan guarantee authority available. DOE currently has loan guarantee authority estimated at about $77 billion and is seeking additional authority. As of April 2010, it had issued one loan guarantee for $535 million and made nine conditional commitments. In response to Congress' mandate to review DOE's execution of the LGP, GAO assessed (1) the extent to which DOE has identified what it intends to achieve through the LGP and is positioned to evaluate progress and (2) how DOE has implemented the program for applicants. GAO analyzed relevant legislation, prior GAO work, and DOE guidance and regulations. GAO also interviewed DOE officials, LGP applicants, and trade association representatives."

Justice Assets Forfeiture Fund: Transparency of Balances and Controls over Equitable Sharing Should Be Improved (open access)

Justice Assets Forfeiture Fund: Transparency of Balances and Controls over Equitable Sharing Should Be Improved

A letter report issued by the Government Accountability Office with an abstract that begins "Annual revenues into the Assets Forfeiture Fund (AFF) from forfeited assets increased from $500 million in 2003 to $1.8 billion in 2011, in part due to an increase in prosecutions of fraud and financial crimes cases. Expenditures in support of forfeiture activities such as equitable sharing payments to state and local law enforcement agencies and payments to victims also increased over the same 9-year period, growing from $458 million in 2003 to $1.3 billion in 2011. The Department of Justice (DOJ) uses the difference between revenues and expenditures in any year to help cover anticipated expenses in the next fiscal year. Because the AFF uses fund revenues to pay for the expenses associated with forfeiture activities, DOJ carries over funds at the end of each fiscal year to ensure it has sufficient resources to cover expenses that may not be covered by the next year’s revenues. When determining the amounts to carry over, DOJ reviews historical data on past program expenditures, analyzes known future expenses such as salaries and contracts, and estimates the costs of any potential new expenditures. However, DOJ has not documented the process …

Security Clearances: Agencies Need Clearly Defined Policy for Determining Civilian Position Requirements (open access)

Security Clearances: Agencies Need Clearly Defined Policy for Determining Civilian Position Requirements

A letter report issued by the Government Accountability Office with an abstract that begins "The Director of National Intelligence (DNI), as Security Executive Agent, has not provided agencies clearly defined policy and procedures to consistently determine if a position requires a security clearance. Executive Order 13467 assigns DNI responsibility for, among other things, developing uniform and consistent policies to determine eligibility for access to classified information, and gives the DNI authority to issue guidance to agency heads to ensure uniformity in processes relating to those determinations. In the absence of this guidance, agencies are using an Office of Personnel Management (OPM) tool that OPM designed to determine the sensitivity and risk levels of civilian positions which, in turn, inform the type of investigation needed. OPM audits, however, found inconsistency in these position designations, and some agencies described problems in implementing OPM’s tool. In an April 2012 audit, OPM reviewed the sensitivity levels of 39 positions in an agency within the Department of Defense (DOD) and reached different conclusions than the agency for 26 of them. Problems exist, in part, because OPM and the Office of the Director of National Intelligence (ODNI) did not collaborate on the development of the position …

Intercollegiate Athletics: Recent Trends in Teams and Participants in National Collegiate Athletic Association Sports

A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1970s, the roles of women as both students and athletes have changed in higher education, with female enrollment surpassing male enrollment, and female athletic participation showing gains as well. These changes have generated public interest in whether women participate in athletics at comparable levels to men and whether men's opportunities have decreased as a result of the increased opportunities for women. Under the Comptroller General's authority, GAO assessed the extent to which the numbers of men's and women's intercollegiate sports teams and participants at 4-year colleges have changed from the 1991-1992 through 2004-2005 school years."

Bankruptcy: Agencies Continue Rulemakings for Clarifying Specific Provisions of Orderly Liquidation Authority

A letter report issued by the Government Accountability Office with an abstract that begins "The federal financial regulators have issued certain final rules for resolving large, complex financial companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act’s (Dodd-Frank Act) established Orderly Liquidation Authority (OLA). Under OLA, the Federal Deposit Insurance Corporation (FDIC) could serve as receiver of a failing financial company instead of the company entering the bankruptcy process. Regulators continue to address a number of issues related to FDIC’s new authority, including how creditors will ensure that they receive no less than they would under a Chapter 7 bankruptcy liquidation; how certain assets and liabilities would be treated in a new company created by FDIC under OLA; and what role the Securities Investor Protection Corporation would play in the resolution of a broker-dealer under OLA. Regulatory officials reported that they were continuing to draft rules to clarify how OLA would be used. FDIC and the Board of Governors of the Federal Reserve (Federal Reserve) also have issued final rules requiring certain financial companies to file resolution plans or “living wills” that must detail how companies would resolve their operations through an orderly bankruptcy. Regulators told GAO that …

Reserve Forces: An Integrated Plan Is Needed to Address Army Reserve Personnel and Equipment Shortages

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) cannot meet its global commitments without continued reserve participation. The Army Reserve provides critical combat support and combat service support units, such as medical and transportation units, to the Army. While Army Reserve members historically could expect to train one weekend a month and 2 weeks a year with activations for limited deployments, since September 11 some have been called upon to support ongoing military operations for a year or more. GAO (1) identified the challenges the Army Reserve faces in continuing to support overseas operations and (2) assessed the extent to which the Army and Army Reserve have taken steps to improve the Army Reserve's readiness for future missions."

Federal Buildings Fund: Improved Transparency and Long-term Plan Needed to Clarify Capital Funding Priorities

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Buildings Fund’s (FBF) balance has increased from $56 million in fiscal year 2007 to $2.2 billion in fiscal year 2012 primarily due to the growing difference between the resources provided to the FBF and the General Services Administration’s (GSA) use of these funds as determined through the budgeting and appropriations process. In the last 2 years, Congress has provided fewer resources than requested by the executive branch and generated by the FBF. Office of Management and Budget (OMB) staff and GSA officials stated that if GSA were able to spend all of the funds collected by the FBF each year, these funds would generally be sufficient to fund GSA’s needs. However, GSA, through the annual President’s Budget Request, has sought less obligational authority than the balance available in the fund. While the FBF’s balance has increased, various factors have limited the fund’s income. Funds from operations—revenue less costs excluding depreciation—that contribute to FBF income have declined from 2006 to 2011 when adjusted for inflation. Revenues have declined while costs have outstripped inflation over this time period. In addition, portions of GSA’s inventory operate at …

Students with Disabilities: Better Federal Coordination Could Lessen Challenges in the Transition from High School

A letter report issued by the Government Accountability Office with an abstract that begins "Students with disabilities face several longstanding challenges accessing services that may assist them as they transition from high school into postsecondary education or the workforce--services such as tutoring, vocational training, and assistive technology. Eligible students with disabilities are entitled to transition planning services during high school, but after leaving high school, to receive services that facilitate their transition they must apply as adults and establish eligibility for programs administered by multiple federal agencies. Students with disabilities may face delays in service and end up on waitlists if these programs are full. In addition, while all five states GAO contacted have taken steps to coordinate their transition services and assist families with the transition process, officials said that it is still difficult for students and their parents to navigate and for providers to coordinate services across different programs. Officials and parents GAO spoke with also noted a lack of sufficient information or awareness of the full range of service options available after high school on the part of students with disabilities, parents, and service providers. In addition, state and local officials said students with disabilities may not …

Federal Advertising: Established Programs Were Largely Used to Address Executive Order Directive to Ensure Small and Minority-Owned Business Participation

A letter report issued by the Government Accountability Office with an abstract that begins "In 2005, federal spending on advertising exceeded $1 billion. Five agencies--DOD, Treasury, HHS, Interior, and NASA--together made up over 90 percent of this spending from 2001 to 2005. Executive Order 13170, signed in October 2000, directs agencies to take an aggressive role in ensuring substantial participation in federal advertising contracts by businesses in the Small Business Administration's (SBA) 8(a) and small disadvantaged business (SDB) programs and minority-owned businesses. This report describes (1) strategies DOD, HHS, Treasury, Interior, and NASA used to address Executive Order 13170, and (2) the total obligations, number of contract actions, and percentage of total obligations represented by these actions that each agency awarded to 8(a)s, SDBs, and minority-owned businesses for advertising services. In conducting this study, GAO analyzed agency contracting data and executive order implementation plans and interviewed agency procurement officials."

Trade Adjustment Assistance: USDA Has Enhanced Technical Assistance for Farmers and Fishermen, but Steps Are Needed to Better Evaluate Program Effectiveness

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Department of Agriculture (USDA) certified relatively few commodities under its Trade Adjustment Assistance (TAA) for Farmers program, as reauthorized by the Trade and Globalization Adjustment Assistance Act of 2009, but provided assistance to most individual farmers and fishermen who produced certified commodities and applied for assistance. Specifically, USDA certified 5 of the 18 commodities for which it received petitions. As of April 2012, USDA approved 9,852, or about 90 percent, of the applicants who produced a certified commodity to participate in the program. In addition, out of the $202.5 million in appropriations for the reauthorized program, USDA paid nearly $50 million in financial assistance to help producers implement long-term business plans in order to become more competitive. GAO identified two issues regarding USDA’s process for approving applications from spouses of producers and providing financial assistance:"

Electronic Waste: Considerations for Promoting Environmentally Sound Reuse and Recycling

A letter report issued by the Government Accountability Office with an abstract that begins "Low recycling rates for used televisions, computers, and other electronics result in the loss of valuable resources, and electronic waste exports risk harming human health and the environment in countries that lack safe recycling and disposal capacity. The Environmental Protection Agency (EPA) regulates the management of used electronics that qualify as hazardous waste and promotes voluntary efforts among electronics manufacturers, recyclers, and other stakeholders. However, in the absence of a comprehensive national approach, a growing number of states have enacted electronics recycling laws, raising concerns about a patchwork of state requirements. In this context, GAO examined (1) EPA's efforts to facilitate environmentally sound used electronics management, (2) the views of various stakeholders on the state-by-state approach, and (3) considerations to further promote environmentally sound management. GAO reviewed EPA documents, interviewed EPA officials, and interviewed stakeholders in five states with electronics recycling legislation."

Medicaid and SCHIP: Recent HHS Approvals of Demonstration Waiver Projects Raise Concerns

A letter report issued by the General Accounting Office with an abstract that begins "States provide health care coverage to about 40 million uninsured, low-income adults and children under two federal-state programs--Medicaid and the State Children's Health Insurance Program (SCHIP). To receive federal funding, states must meet statutory requirements, including providing certain levels of benefits to specified populations. Under section 1115 of the Social Security Act, the Secretary of Health and Human Services (HHS) can waive many of the statutory requirements in the case of experimental, pilot, or demonstration projects likely to promote program objectives. Since August 2001, HHS has approved four of 13 waiver proposals from states to either expand health insurance to uninsured populations or extend pharmacy coverage to low-income seniors, consistent with the new goals. Of the nine proposals still under review, five seek to expand coverage to uninsured populations, while four would provide pharmacy benefits for low-income seniors. GAO has both legal and policy concerns about the extent to which the approved waivers are consistent with the goals and fiscal integrity of Medicaid and SCHIP. The legal concern is that HHS has allowed Arizona to use unspent SCHIP funding to cover adults without children, despite SCHIP's …

Performance Management Systems: IRS's Systems for Frontline Employees and Managers Align with Strategic Goals but Improvements Can Be Made

A letter report issued by the General Accounting Office with an abstract that begins "The Internal Revenue Service (IRS) established critical job responsibilities for group managers and frontline employees that align with each of the agency's three strategic goals. In the group managers' performance management system, all of the supporting behaviors clearly align with the critical job responsibilities. However, for frontline employees, the supporting behaviors do not always align with IRS's description of the critical job responsibilities. Misalignments occur when (1) supporting behaviors reflect concerns not expressed in the description, (2) supporting behaviors that relate to a responsibility are located under other responsibilities, or (3) no supporting behavior exists to support the description. Raters provided feedback on the three critical job responsibilities related to IRS's organizational goals in 90 percent or more of evaluations and provided feedback on leadership and equal employment opportunity in 70 percent of the evaluations. IRS senior executives have no firm plans to monitor how well the group managers' and frontline employees' systems are being implemented or to assess whether changes need to be made, even though IRS's management processes call for obtaining data on how well programs are achieving their goals."

Gun Control: Opportunities to Close Loopholes in the National Instant Criminal Background Check System

A letter report issued by the General Accounting Office with an abstract that begins "The National Instant Criminal Background Check System (NICS) searches state criminal history records to prevent gun sales to ineligible persons. GAO found that state firearm laws and procedures may affect how these records are used by NICS. Each of the six states GAO surveyed had some mechanism by which persons with criminal convictions could have their rights to own a firearm restored. The six states typically require a waiting period before someone can apply for relief, and some criminal convictions make a person ineligible for restoration. In 26 states, the Bureau of Alcohol, Tobacco and Firearms has determined that a concealed carry permit may exempt permit holders from an NICS background check when they are buying a firearm. This situation underscores the need to carefully screen applications and monitor permit holders to ensure their eligibility to own firearms. The six states used various approaches to make it easier to identify individuals convicted of domestic violence. Despite these efforts, NICS failed to detect more than 2,800 persons convicted of domestic violence who bought firearms during the first three years the system was in operation."
