EQUIPOISE-3: A TWO DIMENSIONAL, TWO-GROUP, NEUTRON DIFFUSION CODE FOR THE IBM-7090 COMPUTER (open access)

EQUIPOISE-3: A TWO DIMENSIONAL, TWO-GROUP, NEUTRON DIFFUSION CODE FOR THE IBM-7090 COMPUTER

EQUIPOISE-3 is an IBM-7090 FORTRAN programmed code for the solution of two-group, two-dimensional, neutron diffusion equations. A maximum of 2l00 mesh points may be used, and the code will solve problems in either rectangular or cylindrical geometry. Logarithmic derivative boundary conditions are allowed, and removal of neutrons from both groups is permitted. Adjoint fluxes with the associated fluxadjoint flux regional integrals may be calculated automatically if desired. A constant buckling, group-dependent buckling, or region-dependent buckling may be specified for rectangular geometry. This program is intended to fill the need for a rapid two-dimensional calculation suitable for survey calculations. During the iterative part of the computations, all operations are carried out in the core memory. The magnetic tape memory is used only for input, output, and program storage. The running time for a 1000-point problem requiring 100 iterations would be about 3 min.(auth)

Peacekeeping: Cost Comparison of Actual UN and Hypothetical U.S. Operations in Haiti

A letter report issued by the Government Accountability Office with an abstract that begins "The UN employs about 85,000 military and civilian personnel in peacekeeping operations in 16 countries. The United States has provided about $1 billion annually to support UN peacekeeping operations. In addition, the United States has led and participated in many such operations. UN reports and congressional hearings have raised concerns about accountability for UN peacekeeping operations and the need for reforms. We were asked to provide information relating to the cost and relative strengths of UN and U.S. peacekeeping. In particular, we have (1) compared the cost of the ongoing UN Stabilization Mission in Haiti with the cost that the United States would have incurred had an operation been deemed in the U.S. national interest and undertaken without UN involvement; (2) analyzed factors that could materially affect the estimated costs of a U.S. operation; and (3) identified the strengths of the United States and the UN for leading the operation. We developed our cost estimate of a U.S.-led operation using cost models from the Departments of Defense and State. The estimate is based on various military assumptions, such as the use of primarily active duty troops. …

Bank Secrecy Act: Increased Use of Exemption Provisions Could Reduce Currency Transaction Reporting While Maintaining Usefulness to Law Enforcement Efforts (open access)

Bank Secrecy Act: Increased Use of Exemption Provisions Could Reduce Currency Transaction Reporting While Maintaining Usefulness to Law Enforcement Efforts

A letter report issued by the Government Accountability Office with an abstract that begins "To aid law enforcement efforts against financial crimes, under the Bank Secrecy Act (BSA) depository institutions must file the Treasury Department's Financial Crimes Enforcement Network's (FinCEN) currency transaction report (CTR) form on their customers' cash transactions of more than $10,000. While FinCEN's regulations allow institutions to exempt certain customers, over 15 million CTRs were filed in 2006. Public Law 109-351 directed GAO to report on (1) the usefulness of CTRs to law enforcement; (2) depository institutions' costs of meeting CTR requirements; and (3) ways to encourage use of exemptions to avoid unnecessary CTRs. Among other things, GAO obtained data from FinCEN on CTRs and exemptions from 2004 to 2006, surveyed 115 state and local law enforcement agencies and 680 depository institutions, held structured interviews with officials of federal agencies and depository institutions, and reviewed relevant laws and regulations."

Aviation Safety: Improved Data Collection Needed for Effective Oversight of Air Ambulance Industry (open access)

Aviation Safety: Improved Data Collection Needed for Effective Oversight of Air Ambulance Industry

A letter report issued by the Government Accountability Office with an abstract that begins "Air ambulance transport is widely regarded as improving the chances of survival for trauma victims and other critical patients. However, in recent years, the number of air ambulance accidents has led to increased industry scrutiny by government agencies, the public, the media, and the industry itself. The Federal Aviation Administration (FAA), which provides safety oversight, has been called upon by the National Transportation Safety Board (NTSB) and others to issue more stringent safety requirements for the industry. GAO's study addressed (1) recent trends in the air ambulance industry, (2) FAA's challenges in providing safety oversight, and (3) FAA's efforts to address the challenges and what is known about the effects of these efforts. To address these issues, we analyzed FAA, NTSB, and industry data, interviewed federal and industry officials, and conducted five site visits, among other things."

DOD Supply Chain: Suspect Counterfeit Electronic Parts Can Be Found on Internet Purchasing Platforms

A letter report issued by the Government Accountability Office with an abstract that begins "Suspect counterfeit and bogus—part numbers that are not associated with any authentic parts—military-grade electronic parts can be found on Internet purchasing platforms, as none of the 16 parts vendors provided to GAO were legitimate. “Suspect counterfeit,” which applies to the first two categories of parts that were tested, is the strongest term used by an independent testing lab, signifying a potential violation of intellectual property rights, copyrights, or trademark laws, or misrepresentation to defraud or deceive. After submitting requests for quotes on both platforms, GAO received responses from 396 vendors, of which 334 were located in China; 25 in the United States; and 37 in other countries, including the United Kingdom and Japan. Of the 16 parts purchased, vendors usually responded within a day. GAO selected the first of any vendor among those offering the lowest prices that provided enough information to purchase a given part, generally within 2 weeks. Under GAO’s selection methodology, all 16 parts were provided by vendors in China."

Department of Health and Human Services: Controls over Travel Program Are Generally Effective, but Some Improvements Are Needed

A letter report issued by the General Accounting Office with an abstract that begins "By their nature, determining and paying allowable travel costs pose substantial risk, making effective internal control crucial. Because of this and weaknesses in internal control identified in the GAO review of travel card usage at the Department of Defense, GAO was requested to review the Department of Health and Human Services' (HHS) travel program. GAO assessed whether HHS's process for monitoring travel charge cards helps minimize delinquencies, write-offs, and unauthorized use. GAO also assessed whether controls over travel voucher processing help ensure proper reimbursements. GAO tested a statistical sample of travel card transactions at each of five HHS component agencies to determine if they were for authorized purposes. GAO also reviewed related travel vouchers to determine if reimbursement amounts were proper."

Environmental Protection: EPA Should Strengthen Its Efforts to Measure and Encourage Pollution Prevention (open access)

Environmental Protection: EPA Should Strengthen Its Efforts to Measure and Encourage Pollution Prevention

A chapter report issued by the General Accounting Office with an abstract that begins "Limited quantitative data exists on the extent to which American industry has sought to use pollution prevention methods to reduce pollutants discharged from its facilities. This shortcoming has inhibited the Environmental Protection Agency's (EPA) efforts to monitor and encourage companies' use of pollution prevention measures. Whether to undertake pollution prevention is typically a business decision that is influenced largely by a company's judgment as to whether an investment in pollution prevention will benefit it financially. One notable exception is the design of environmental regulations, some of which have had the unintended consequence of discouraging pollution prevention practices. In some cases, EPA may have no means to address them. The design of some regulations may be constrained by their governing statutes. In other cases, EPA may be better able to take the national goal of promoting pollution prevention into consideration in developing its regulatory proposals. The Pollution Prevention Act requires EPA to review its regulatory proposals to determine their effects on source reduction. However, the agency has not systematically tracked the implementation of this provision, and therefore does not know the extent to which source reduction has …

2020 Census: Local Administrative Records and Their Use in the Challenge Program and Decennial

A letter report issued by the Government Accountability Office with an abstract that begins "The Census Bureau (Bureau) issued significant changes to rules governing the records that communities use to challenge the Bureau's population estimates. Previously, the Bureau routinely accepted all challenges, largely without regard to the data sources cited or provided so long as they supported the calculations and covered the appropriate reporting periods. According to Bureau officials, these changes are based on research that shows that estimates based on some methods and records (e.g., births, deaths, and migration) are substantially more accurate than estimates based on others. Among other changes, the Bureau modified procedures so that challenges by subcounty governments to the Bureau's estimates of people living in housing units will no longer affect countylevel population estimates. Moving forward, any such challenge resulting in an increase in the estimate of a subcounty population will be offset by a downward revision to the population estimate of all other communities in the same county. Also, the Bureau plans to routinely review population challenges in light of each community's population growth trend.Corroborating data will be required for challenges inconsistent with the trend."

DOE EPSCoR Initiative in Structural and computational Biology/Bioinformatics (open access)

DOE EPSCoR Initiative in Structural and computational Biology/Bioinformatics

The overall goal of the DOE EPSCoR Initiative in Structural and Computational Biology was to enhance the competiveness of Vermont research in these scientific areas. To develop self-sustaining infrastructure, we increased the critical mass of faculty, developed shared resources that made junior researchers more competitive for federal research grants, implemented programs to train graduate and undergraduate students who participated in these research areas and provided seed money for research projects. During the time period funded by this DOE initiative: (1) four new faculty were recruited to the University of Vermont using DOE resources, three in Computational Biology and one in Structural Biology; (2) technical support was provided for the Computational and Structural Biology facilities; (3) twenty-two graduate students were directly funded by fellowships; (4) fifteen undergraduate students were supported during the summer; and (5) twenty-eight pilot projects were supported. Taken together these dollars resulted in a plethora of published papers, many in high profile journals in the fields and directly impacted competitive extramural funding based on structural or computational biology resulting in 49 million dollars awarded in grants (Appendix I), a 600% return on investment by DOE, the State and University.

Earth Systems Science and Engineering

Providing the essential energy and water systems to support human needs while understanding and addressing their environmental consequences is a watershed problem for the 21st century. The LLNL Earth System Science and Engineering Program seeks to provide the scientific understanding and technological expertise to help provide solutions at both global and regional scales. Our work is highly collaborative with universities, laboratories and industrial partners across the world and involves observational data, laboratory experiments, and numerical simulations. The energy systems we have enjoyed for the last 100 years have resulted in the advanced standard of living in the developed world and a major emerging problem with climate change. Now we face a simultaneous realization that our reliance on fossil fuels is a source of conflict and economic disruption as well as causing potentially abrupt, even catastrophic global climate change. The climate and energy problem is perhaps the greatest challenge ever faced by mankind. Fossil fuel remains the least expensive and most available source of energy and the basis of our economy. The use of fossil fuels, especially over the last 100 years has led to a 30% increase in CO{sub 2} in the atmosphere. The problem is growing. The population of …

OFFICE OF SCIENCE AND TECHNOLOGY AND INTERNATIONAL, NATURAL BARRIERS THRUST OVERVIEW

The Natural Barriers Thrust supports scientific studies of the natural system at the proposed repository site of Yucca Mountain. It stresses the realistic representation of the natural system with respect to processes and parameters, by means of laboratory, field, and modeling studies. It has the objectives to demonstrate that the natural barriers can make large contributions to repository performance, supporting the multiple-barrier concept for geological disposal of high-level radioactive waste; and to reduce the overall cost of repository development by elimination of unnecessary engineered components, given the demonstrated natural barriers performance. In this overview we enumerate the research projects within the Natural Barriers Thrust grouped under five elements: (1) Drift Seepage, (2) In-drift Environment, (3) Drift Shadow, (4) Unsaturated Zone Flow and Transport, and (5) Saturated Zone Flow and Transport. The long-term strategic plan of the Natural Barriers Thrust and some key results are also briefly described.

A Review of Tribological Coatings for Control Drive Mechanisms in Space Reactors (open access)

A Review of Tribological Coatings for Control Drive Mechanisms in Space Reactors

Tribological coatings must provide lubrication for moving components of the control drive mechanism for a space reactor and prevent seizing due to friction or diffusion welding to provide highly reliable and precise control of reflector position over the mission lifetime. Several coatings were evaluated based on tribological performance at elevated temperatures and in ultrahigh vacuum environments. Candidates with proven performance in the anticipated environment are limited primarily to disulfide materials. Irradiation data for these coatings is nonexistent. Compatibility issues between coating materials and structural components may require the use of barrier layers between the solid lubricant and structural components to prevent deleterious interactions. It would be advisable to consider possible lubricant interactions prior to down-selection of structural materials. A battery of tests was proposed to provide the necessary data for eventual solid lubricant/coating selection.
