Pulse*Star Inertial Confinement Fusion Reactor: heat transfer loop and balance of plant considerations
A conceptual heat transfer loop and balance of plant design for the Pulse*Star Inertial Confinement Fusion Reactor has been investigated and results are presented. The Pulse*Star reaction vessel, a perforated steel bell jar approximately 11 m in diameter, is immersed in Li/sub 17/Pb/sub 83/ coolant which flows through the perforations and forms a 1.5 m thick plenum of droplets around an 8 m diameter inner chamber. The reactor and associated pumps, piping, and steam generators are contained within a 17 m diameter pool of Li/sub 17/Pb/sub 83/ coolant to minimize structural requirements and occupied space, resulting in reduced cost. Four parallel heat transfer loops with flow rates of 5.5 m/sup 3//s each are necessary to transfer 3300 MWt of power. The steam generator design was optimized by finding the most cost-effective combination of heat exchanger area and pumping power. Power balance calculations based on an improved electrical conversion efficiency revealed a net electrical output of 1260 MWe to the bus bar and a resulting net efficiency of 39%. Suggested balance-of-plant layouts are also presented.

Numerical simulation of an accelerator injector
Accelerator injector designs have been evaluated using two computer codes. The first code self consistently follows relativistic particles in two dimensions. Fields are obtained in the Darwin model which includes inductive effects. This code is used to study cathode emission and acceleration to full injector voltage. The second code transports a fixed segment of a beam along the remainder of the beam line. Using these two codes the effects of electrode configuration on emittance, beam quality and beam transport have been studied.

Offshore Marine Aquaculture: Multiple Administrative and Environmental Issues Need to Be Addressed in Establishing a U.S. Regulatory Framework
A letter report issued by the Government Accountability Office with an abstract that begins "U. S. aquaculture--the raising of fish and shellfish in captivity--has generally been confined to nearshore coastal waters or in other water bodies, such as ponds, that fall under state regulation. Recently, there has been an increased interest in expanding aquaculture to offshore waters, which would involve raising fish and shellfish in the open ocean, and consequently bringing these types of operations under federal regulation. While the offshore expansion has the potential to increase U.S. aquaculture production, no comprehensive legislative or regulatory framework to manage such an expansion exists. Instead, multiple federal agencies have authority to regulate different aspects of offshore aquaculture under a variety of existing laws that were not designed for this purpose. In this context, GAO was asked to identify key issues that should be addressed in the development of an effective regulatory framework for U.S. offshore aquaculture. In conducting its assessment, GAO administered a questionnaire to a wide variety of key aquaculture stakeholders; analyzed laws, regulations, and key studies; and visited states that regulate nearshore aquaculture industries. Although GAO is not making any recommendations, this review emphasizes the need to carefully consider a …

General Services Administration Could Better Manage Unexpended Construction Balances and Make Its Budget More Transparent
Correspondence issued by the Government Accountability Office with an abstract that begins "The General Services Administration (GSA) is the federal government's principal real estate agent, with responsibilities including constructing, leasing, and maintaining a variety of facilities--such as office buildings, courthouses, border stations, and laboratories--that it rents to federal agencies. GSA's construction projects, which can span several years, are authorized to carry forward fund balances from year to year in its construction and facility accounts for these projects. GSA is responsible for keeping track of and managing these balances to ensure that any unexpended funds that remain after projects are completed are redirected to other construction project needs within the agency. GSA is required to identify construction projects that are estimated to cost in excess of established thresholds and obtain congressional approval for them. Funding for these projects exists in two accounts: (1) Construction and Acquisition and (2) Repairs and Alterations. For the purposes of this report, we refer to them as GSA's construction accounts. Additionally, the studies required for construction projects are among the items funded in the Building Operations account and we decided to include this account in our review. For purposes of this report, we refer to this …

Stabilizing and Rebuilding Iraq: Coalition Support and International Donor Commitments
Testimony issued by the Government Accountability Office with an abstract that begins "In March 2003, a U.S.-led multinational force began operations in Iraq. At that time, 48 nations, identified as a "coalition of the willing," offered political, military, and financial support for U.S. efforts in Iraq, with 38 nations other than the United States providing troops. In addition, international donors met in Madrid in October 2003 to pledge funding for the reconstruction of Iraq's infrastructure, which had deteriorated after multiple wars and decades of neglect under the previous regime. This testimony discusses (1) the troop commitments other countries have made to operations in Iraq, (2) the funding the United States has provided to support other countries' participation in the multinational force, and (3) the financial support international donors have provided to Iraq reconstruction efforts. This testimony is based on GAO's prior work and data collected for this hearing. Although we reviewed both classified and unclassified documents, the information in this statement is based only on unclassified documents. We completed this work in accordance with generally accepted government auditing standards."

Homeland Security: DHS Enterprise Architecture Continues to Evolve but Improvements Needed
A letter report issued by the Government Accountability Office with an abstract that begins "GAO designated the transformation of the Department of Homeland Security (DHS) as high risk in 2003, and it continues to do so today. One essential tool for facilitating organizational transformation is an enterprise architecture (EA)--a corporate blueprint that serves as an authoritative frame of reference for information technology investment decision making. The Congress required DHS to submit a report that includes its EA and a capital investment plan for implementing it. The Congress also required that GAO review the report. In June 2006, DHS submitted this report to the Congress. GAO's objective was to assess the status of the EA, referred to as DHS EA 2006, and the plan for implementing it. To meet this objective, GAO analyzed architectural documents relative to its prior recommendations; evaluated stakeholder comments and the process used to obtain them; and analyzed the implementation plan against relevant guidance."

Overseas Security: State Department Has Not Fully Implemented Key Measures to Protect U.S. Officials from Terrorist Attacks Outside of Embassies
A letter report issued by the Government Accountability Office with an abstract that begins "U.S. government officials working overseas are at risk from terrorist threats. Since 1968, 32 embassy officials have been attacked--23 fatally--by terrorists outside the embassy. As the State Department continues to improve security at U.S. embassies, terrorist groups are likely to focus on "soft" targets--such as homes, schools, and places of worship. GAO was asked to determine whether State has a strategy for soft target protection; assess State's efforts to protect U.S. officials and their families while traveling to and from work; assess State's efforts overseas to improve security at schools attended by the children of U.S. officials; and describe issues related to protection at their residences."

Research and Development Funding: Reported Gap Between Data From Federal Agencies and Their R&D Performers Results From Noncomparable Data
Correspondence issued by the General Accounting Office with an abstract that begins "A January report by the National Science Foundation (NSF) identified a $5 billion gap between the amount of money that federal agencies reported as research and development (R&D) support and the amount of money that those who did the R&D work reported as spent in 1998. According to NSF, federal agencies earmarked about $72 billion for R&D support in 1998, while those who carried out the R&D reported spending about $67 billion. GAO found that this gap results primarily from annually comparing two separate and distinct types of financial data--federal obligations and performer expenditures--that are not comparable. In addition, R&D funding are collected on a yearly basis, but,in reporting, the period that defines a year can vary. Furthermore, agencies and performers do not always agree on what type of activities fall under the category of R&D. Because the gap results from comparing two dissimilar types of financial data, it does not necessarily reflect poor-quality data, nor does it reflect whether performers are receiving or spending all the federal R&D funds obligated to them. Thus, even if the data collection and reporting issues were addressed, a gap would still …

School Meal Programs: Revenue and Expense Information from Selected States
A letter report issued by the General Accounting Office with an abstract that begins "The National School Lunch and Breakfast Programs provide millions of children with low-cost or free nutritious meals each school day. In school year 1996-97, the Department of Agriculture instituted more stringent requirements for the nutritional content of school meals. GAO was asked to study the school food service revenues and expenses and how they have changed since the requirements went into effect. This report includes information on the sources of revenues available for providing meals, the expenses of producing meals, the revenues compared to expenses, and the approaches that local school food authorities have adopted to manage their school food service finances. It uses data from six selected states. This report does not provide specific information on the expense of producing a reimbursable school lunch or breakfast."

Climate Change: Expert Opinion on the Economics of Policy Options to Address Climate Change
A letter report issued by the Government Accountability Office with an abstract that begins "Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant environmental and economic impacts in the United States and internationally. Potential impacts include rising sea levels and a shift in the intensity and frequency of floods and storms. Proposed responses to climate change include adapting to the possible impacts by planning and improving protective infrastructure, and reducing greenhouse gas emissions directly through regulation or the promotion of low-emissions technologies. Because most U.S. emissions stem from the combustion of fossil fuels such as coal, oil, and natural gas, much of this report centers on the effect emissions regulation could have on the economy. In this context, GAO was asked to elicit the opinions of experts on (1) actions the Congress might consider to address climate change and what is known about the potential benefits, costs, and uncertainties of these actions and (2) the key strengths and limitations of policies or actions to address climate change. GAO worked with the National Academy of Sciences to identify a panel of noted economists with expertise in analyzing the economic impacts of …

Medicare: Review of the First Year of CMS's Durable Medical Equipment Competitive Bidding Program's Round 1 Rebid
A letter report issued by the Government Accountability Office with an abstract that begins "The Centers for Medicare and Medicaid Services (CMS), within the Department of Health and Human Services (HHS), implemented the durable medical equipment (DME) competitive bidding programs (CBP) bidding process for the round 1 rebid. Nearly the same number of suppliers submitted a similar number of bids for both the CBP round 1 rebid and round 1. Many suppliers continued to have difficulty complying with financial documentation requirements; however, the number of bids disqualified in the round 1 rebid was significantly less than for round 1. After being notified of their bid results, some suppliers were found to have bids that were disqualified incorrectly and were subsequently offered round 1 rebid contracts. About one-third of the bidding suppliers were awarded CBP contracts."

Medicare Program Integrity: Few Payments in 2011 Exceeded Limits under One Kind of Prepayment Control, but Reassessing Limits Could Be Helpful
A letter report issued by the Government Accountability Office with an abstract that begins "Less than 0.1 percent of payments Medicare made in 2011 were for amounts of services that exceeded certain unpublished limits for excess billing and where the claims did not include information from the providers to indicate why the additional services were medically necessary. These limits are set by the Centers for Medicare & Medicaid Services (CMS)--an agency within the Department of Health and Human Services (HHS)--as a means to avoid potentially improper payments. To implement these limits, CMS established automated controls in its payment systems called Medically Unlikely Edits (MUE). These MUEs compare the number of certain services billed against limits for the amount of services likely to be provided under normal medical practice to a beneficiary by the same provider on the same day--for example, no more than one of the same operation on each eye. GAO analysis of 2011 claims data found approximately $14 million out of a total of $23.9 billion in Medicare payments for services that exceeded unpublished MUE limits and where the claims did not include information from the providers to indicate why the additional services were medically necessary. As GAO …

Medicare: The First Year of the Durable Medical Equipment Competitive Bidding Program Round 1 Rebid
Testimony issued by the Government Accountability Office with an abstract that begins "Our work on the outcomes of the CBP round 1 rebid found that the number of bidding suppliers and the number of contracts awarded in the CBP round 1 rebid were very similar to the CBP round 1 and about a third of the 1,011 suppliers that bid in the rebid were awarded at least one CBP contract. CMS made improvements to the bidding process for the CBP round 1 rebidsuch as providing additional information about disqualification reasonsand significantly fewer bids were disqualified than in round 1. However, many suppliers still had difficulty meeting bid requirements. Of the bids that were disqualified during the initial bid review, 73 percent were disqualified because suppliers failed to provide the required financial documentation or did not meet CMSs minimum financial standard threshold for suppliers. The number of bids disqualified for missing financial documentation in the CBP round 1 rebid would have been higher if many suppliers had not benefited from a MIPPA provision that required that CMS provide suppliers the opportunity to be notified of and to submit missing required financial documentationa process not available during CBP round 1.
