Analysis of granular flow in a pebble-bed nuclear reactor (open access)

Analysis of granular flow in a pebble-bed nuclear reactor

Pebble-bed nuclear reactor technology, which is currently being revived around the world, raises fundamental questions about dense granular flow in silos. A typical reactor core is composed of graphite fuel pebbles, which drain very slowly in a continuous refueling process. Pebble flow is poorly understood and not easily accessible to experiments, and yet it has a ma jor impact on reactor physics. To address this problem, we perform full-scale, discrete-element simulations in realistic geometries, with up to 440,000 frictional, viscoelastic 6cm-diameter spheres draining in a cylindrical vessel of diameter 3.5m and height 10m with bottom funnels angled at 30◦ or 60◦ . We also simulate a bidisperse core with a dynamic central column of smaller graphite moderator pebbles and show that little mixing occurs down to a 1:2 diameter ratio. We analyze the mean velocity, diffusion and mixing, local ordering and porosity (from Voronoi volumes), the residence-time distribution, and the effects of wall friction and discuss implications for reactor design and the basic physics of granular flow.

Aviation Security: Enhancements Made in Passenger and Checked Baggage Screening, but Challenges Remain

Testimony issued by the Government Accountability Office with an abstract that begins "Securing commercial aviation is a daunting task--with hundreds of airports, thousands of aircraft, and thousands of flights daily carrying millions of passengers and pieces of checked baggage. It has been over 3 years since the Transportation Security Administration (TSA) assumed responsibility for passenger and baggage screening at commercial airports. This testimony focuses on the progress TSA is making in strengthening airline passenger and checked baggage screening and the challenges that remain. Particularly, this testimony highlights TSA's efforts to (1) enhance the performance, management, and deployment of the transportation security officer (TSO) workforce; (2) strengthen procedures for screening passengers and checked baggage; and (3) leverage and deploy screening technologies."

Border Security: Reassessment of Consular Resource Requirements Could Help Address Visa Delays

Testimony issued by the Government Accountability Office with an abstract that begins "In deciding to approve or deny a visa application, the Department of State's (State) consular officers are on the front line of defense in protecting the United States against those who seek to harm U.S. interests. To increase border security following the September 11 attacks, Congress, State, and the Department of Homeland Security initiated a series of changes to border security policies and procedures. These changes have added to the complexity of consular workload. But consular officers must balance this security responsibility against the need to facilitate legitimate travel. In recent years, GAO has issued a series of reports on the visa process. This statement discusses (1) wait times for visas, (2) factors that affect wait times, and (3) GAO's recent work on consular staffing."

Defense Acquisitions: Actions Needed to Get Better Results on Weapons Systems Investments (open access)

Defense Acquisitions: Actions Needed to Get Better Results on Weapons Systems Investments

Testimony issued by the Government Accountability Office with an abstract that begins "In the past 5 years, DOD has doubled its planned investments in weapons systems, but this huge increase has not been accompanied by more stability, better outcomes, or more buying power for the acquisition dollar. Rather than showing appreciable improvement, programs are experiencing recurring problems with cost overruns, missed deadlines, and performance shortfalls. GAO was asked to testify on ways to obtain a better return on DOD's weapons systems investments. This testimony identifies the following steps as needed to provide a better foundation for executing weapon programs: (1) developing a DOD-wide investment strategy that prioritizes programs based on realistic and credible threat-based customer needs for today and tomorrow, (2) enforcing existing policies on individual acquisitions and adhering to practices that assure new programs are executable, and (3) making it clear who is responsible for what and holding people accountable when these responsibilities are not fulfilled. Past GAO reports have made similar recommendations."

Defense Acquisitions: DOD Wastes Billions of Dollars through Poorly Structured Incentives (open access)

Defense Acquisitions: DOD Wastes Billions of Dollars through Poorly Structured Incentives

Testimony issued by the Government Accountability Office with an abstract that begins "With DOD spending over $200 billion annually to acquire products and services that include everything from spare parts to the development of major weapon systems, our numerous, large, and mounting fiscal challenges demand that DOD maximize its return on investment and provide the warfighter with needed capabilities at the best value for the taxpayer. In an effort to encourage defense contractors to perform in an innovative, efficient, and effective way, DOD gives its contractors the opportunity to collectively earn billions of dollars through monetary incentives known as award and incentive fees. Using these incentives properly--in concert with good acquisition practices--is a key to minimizing waste, maximizing value, and getting our military personnel what they need, when and where they need it. Congress asked GAO to testify on DOD's use of award and incentive fees and the role they play in the acquisition system. This statement highlights the risks of conducting business as usual and identifies the actions DOD needs to take to use these fees more effectively. DOD concurred or partially concurred with the seven recommendations GAO made in a previously issued report on award and incentive fees. …

Defense Acquisitions: Improved Business Case Key for Future Combat System's Success (open access)

Defense Acquisitions: Improved Business Case Key for Future Combat System's Success

Testimony issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) is a networked family of weapons and other systems in the forefront of efforts by the Army to become a lighter, more agile, and more capable combat force. When considering complementary programs, projected investment costs for FCS are estimated to be on the order of $200 billion. FCS's cost is of concern given that developing and producing new weapon systems is among the largest investments the government makes, and FCS adds significantly to that total. Over the last 5 years, the Department of Defense (DOD) doubled its planned investments in such systems from $700 billion in 2001 to $1.4 trillion in 2006. At the same time, research and development costs on new weapons continue to grow on the order of 30 to 40 percent. FCS will be competing for significant funds at a time when federal fiscal imbalances are exerting great pressures on discretionary spending. In the absence of more money being available, FCS and other programs must be executable within projected resources. Today, I would like to discuss (1) the business case needed for FCS to be successful and (2) our recent …

Department of Defense Actions to Modify its Commercial Communications Satellite Services Procurement Process

Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) continues to rely on commercial satellite communications to plan and support operations. DOD use of commercial satellite bandwidth has increased over the past few years, making the department the largest single customer of commercial satellite bandwidth. In recent years, DOD's process for acquiring commercial satellite communications has received criticism for being lengthy, inflexible, and costly. DOD is now reexamining how it procures commercial satellite services to address these issues. Congress asked us to summarize the actions that DOD has taken to date in revising its requirements and acquisition approach for commercial satellite services."

Endangered Species: Time and Costs Required to Recover Species Are Largely Unknown (open access)

Endangered Species: Time and Costs Required to Recover Species Are Largely Unknown

Correspondence issued by the Government Accountability Office with an abstract that begins "The Endangered Species Act of 1973 protects species facing extinction (endangered species) or likely to face extinction (threatened species) and the ecosystems upon which they depend. The act has long been a lightning rod for political debate about the extent to which the nation's natural resources should be protected and how best to protect them. Implementation of the act has also been the subject of numerous lawsuits that have consumed significant program resources. Since the act's inception, about 1,300 domestic species have been placed on the list of threatened and endangered species. Supporters of the act claim it is an indication of the act's success that only 9 of these species have gone extinct; particularly, since by the time they are listed species, they are often in critical condition. Critics, on the other hand, counter that it is an indication of the act's failure that only 17 of these species have "recovered," or improved to the point that they no longer need the act's protection. However, we believe that these numbers, by themselves, are not a good gauge of the act's success or failure; additional information on when, …

Export Promotion: Trade Promotion Coordinating Committee's Role Remains Limited

Testimony issued by the Government Accountability Office with an abstract that begins "In 1992, Congress established the Trade Promotion Coordinating Committee (TPCC) to provide a unifying interagency framework to coordinate U.S. export promotion activities and to develop a governmentwide strategic plan. TPCC member agencies' activities include providing training, market information, advocacy, trade finance and other services to U.S. companies, especially small- and medium-sized businesses. These U.S. government agencies together have $1.5 billion in budget authority for export promotion programs and activities for fiscal year 2006. Each year, the TPCC submits to Congress a mandated national export strategy, reporting member agencies' activities and trade promotion budget authority and establishing broad priorities. The TPCC secretariat, which has no budget of its own, is housed in the Commerce Department, which chairs the committee. In this testimony, which updates findings from a 2002 report, GAO (1) reports on trends in TPCC member agencies' budget authority; (2) assesses TPCC's coordination of trade promotion and its national export strategies; and (3) discusses small- and medium-sized businesses' participation in trade promotion activities."

Final report (open access)

Final report

High performance computational science and engineering simulations have become an increasingly important part of the scientist's problem solving toolset. A key reason is the development of widely used codes and libraries that support these applications, for example, Netlib, a collection of numerical libraries [33]. The term community codes refers to those libraries or applications that have achieved some critical level of acceptance by a user community. Many of these applications are on the high-end in terms of required resources: computation, storage, and communication. Recently, there has been considerable interest in putting such applications on-line and packaging them as network services to make them available to a wider user base. Applications such as data mining [22], theorem proving and logic [14], parallel numerical computation [8][32] are example services that are all going on-line. Transforming applications into services has been made possible by advances in packaging and interface technologies including component systems [2][6][13][28][37], proposed communication standards [34], and newer Web technologies such as Web Services [38]. Network services allow the user to focus on their application and obtain remote service when needed by simply invoking the service across the network. The user can be assured that the most recent version of the …

Financial Management: Challenges Continue in Meeting Requirements of the Improper Payments Information Act

Testimony issued by the Government Accountability Office with an abstract that begins "Improper payments are a long-standing, widespread, and significant problem in the federal government. The Congress enacted the Improper Payments Information Act of 2002 (IPIA) to address this issue. Fiscal year 2005 marked the second year that agencies were required to report improper payment information under IPIA. One result of IPIA has been increased visibility over improper payments by requiring executive branch agencies to identify programs and activities susceptible to significant improper payments, estimate the amount of their improper payments, and report on the amounts of improper payments and their actions to reduce them in their annual performance and accountability reports (PAR). Because of continued interest in addressing the governmentwide improper payments issue, GAO was asked to report on the progress made by agencies in complying with requirements of IPIA and the status of efforts to identify, reduce, and eliminate improper payments. As part of the review, GAO looked at (1) the extent to which agencies have performed risk assessments, (2) the annual amount of improper payments estimated, and (3) the amount of improper payments recouped through recovery audits."
