Method for producing nuclear fuel
Nuclear fuel is made by contacting an aqueous solution containing an actinide salt with an aqueous solution containing ammonium hydroxide, ammonium oxalate, or oxalic acid in an amount that will react with a fraction of the actinide salt to form a precipitate consisting of the hydroxide or oxalate of the actinide. A slurry consisting of the precipitate and solution containing the unreacted actinide salt is formed into drops which are gelled, calcined, and pressed to form pellets.

Wear and corrosion performance of metallurgical coatings in sodium
The friction, wear, and corrosion performance of several metallurgical coatings in 200 to 650/sup 0/C sodium are reviewed. Emphasis is placed on those coatings which have successfully passed the qualification tests necessary for acceptance in breeder reactor environments. Tests include friction, wear, corrosion, thermal cycling, self-welding, and irradiation exposure under as-prototypic-as-possible service conditions. Materials tested were coatings of various refractory metal carbides in metallic binders, nickel-base and cobalt-base alloys and intermetallic compounds such as the aluminides and borides. Coating processes evaluated included plasma spray, detonation gun, sputtering, spark-deposition, and solid-state diffusion.

Stress-Relief Displacements Induced by Drilling--Applications to Holographic Measurements of in Situ Stress
The holographic stressmeter is an instrument which has been developed at Caltech to allow determination of the complete stress tensor from in situ borehole measurements. The stressmeter uses double-exposure holographic interferometry to record the displacements induced by the drilling of a small sidehole into the borehole wall. The local stresses, which are the result of the far-field stresses, concentrated at the borehole, cause deformation of the surface of the borehole wall in the vicinity of the sidehole. The first part of this study uses a thin infinite elastic plate subjected to plane stress at infinity to model the displacements at the borehole wall. However, the existence of some holograms which were difficult to model closely led us to examine the validity of this model. In order to investigate the problem further, we performed a two-dimensional finite element analysis for an elastic box with a terminated hole. We varied the dimensions of the hole to see what effect the radius and depth of the hole might have on the displacements. The plate model predicts that the depth of the hole should have no effect on the horizontal components of displacement, but the finite element results show that the magnitude of both …

Title Insurance: Preliminary Views and Issues for Further Study
A letter report issued by the Government Accountability Office with an abstract that begins "Title insurance is a required element of almost all real estate purchases and is not an insignificant cost for consumers. However, consumers generally do not have the knowledge needed to "shop around" for title insurance and usually rely on professionals involved in real estate--such as lenders, real estate agents, and attorneys--for advice in selecting a title insurer. Recent state and federal investigations into title insurance sales have identified practices that may have benefited these professionals and title insurance providers at the expense of consumers. At your request, GAO currently has work under way studying the title insurance industry, including pricing, competition, the size of the market, the roles of the various participants in the market, and how they are regulated. You asked GAO to identify and report on preliminary issues for further study. In so doing, this report focuses on: (1) the reasonableness of cost structures and agent practices common to the title insurance market that are not typical of other insurance markets; (2) the implications of activities identified in recent state and federal investigations that may have benefited real estate professionals rather than consumers; and …

Managing for Results: Human Capital Management Discussions in Fiscal Year 2001 Performance Plans
A letter report issued by the General Accounting Office with an abstract that begins "The Government Performance and Results Act calls for agencies to address human capital in the context of performance-based management. The act requires that annual performance plans describe how agencies will use their human capital to accomplish their goals and objectives. Designing, implementing, and maintaining a strategic human capital management focus are critical to maximizing performance and ensuring that government is accountable to the American people. GAO found that the human capital challenges described in fiscal year 2001 performance plans reflected the different levels of attention agencies are to pay this critical issue. GAO contends that the breadth, depth, and specificity of many related human capital goals and strategies needs to be increased. The plans' discussions of human capital increasingly need to focus on describing human capital challenges. The plans need to specify the what, why, how, and when of the strategies to address those challenges. The discussions should also better link human capital management and the agencies' strategic and program planning to maximize performance and ensure optimal resource allocation. Overall, the fiscal year 2001 plans showed that substantial opportunities exist for goals and strategies as they …

Defense Infrastructure: Continued Management Attention Is Needed to Support Installation Facilities and Operations
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) manages and operates about 577,000 structures worldwide, valued at about $712 billion. DOD has worked for several years to develop models that can reliably estimate the installation support funds needed to sustain these facilities, and plans to spend over $55 billion to support these facilities and operate its bases in fiscal year 2008. Because GAO has identified support infrastructure as a high-risk area that affects DOD's ability to devote funds to other more critical needs, GAO initiated this review under the Comptroller General's authority. This report discusses (1) the reliability of the annual funding estimates produced by the facilities sustainment model, (2) DOD's progress in meeting funding goals for facility sustainment and recapitalization, (3) the extent to which DOD has addressed deferred facility sustainment funding needs, and (4) the status of DOD's efforts to develop a new installation services model. To address these objectives, GAO reviewed the accuracy and support for the model's key inputs, analyzed pertinent documents, and visited eight judgmentally selected installations."

Spectrum Management: Preliminary Findings on Federal Relocation Costs and Auction Revenues
Testimony issued by the Government Accountability Office with an abstract that begins "Actual costs to relocate federal users from the 1710-1755 megahertz (MHz) band have exceeded the original $1 billion estimate by about $474 million as of March 2013, although auction revenues appear to exceed relocation costs by over $5 billion. Actual relocation costs exceed estimated costs for various reasons, including unforeseen challenges and some agencies not following the National Telecommunications and Information Administration's (NTIA) guidance for preparing the cost estimate. In contrast, the Department of Defense (DOD) expects to complete relocation for about $275 million or approximately $80 million less than its $355 million estimate. According to DOD officials, the relocation of systems from this band has been less expensive than originally estimated because many systems were simply re-tuned to operate in the adjacent 1755-1850 MHz band. The auction of the 1710-1755 MHz band raised almost $6.9 billion in gross winning bids. NTIA expects agencies to complete the relocation effort between 2013 and 2017; therefore, final net auction revenue (auction revenue less relocation costs) may change."

NASA: Challenges in Completing and Sustaining the International Space Station
Testimony issued by the Government Accountability Office with an abstract that begins "The International Space Station (ISS), the most complex scientific space project ever attempted, remains incomplete. NASA expects the station's final construction cost will be $31 billion and expects sustainment costs through the station's planned retirement in fiscal year 2016 to total $11 billion. The space shuttle, the only vehicle capable of transporting large segments of the station into orbit, is critical to its completion. NASA plans to complete ISS assembly and retire the shuttle in 2010 in order to pursue a new generation of space flight vehicles, which will not begin to be available until 2015. To provide crew rotation and logistical support during this 5-year gap, NASA plans to rely on spacecraft developed by the commercial sector and other countries. In light of these circumstances, GAO examined the risks and challenges NASA faces in (1) completing assembly of the ISS by 2010 and (2) providing logistics and maintenance to the ISS after 2010. GAO's work to accomplish this included reviewing budget, planning, and other documents from NASA; reviewing NASA officials' testimonies; and interviewing NASA and foreign space program officials."

Cybersecurity: Threats Impacting the Nation
Testimony issued by the Government Accountability Office with an abstract that begins "The nation faces an evolving array of cyber-based threats arising from a variety of sources. These threats can be intentional or unintentional. Unintentional threats can be caused by software upgrades or defective equipment that inadvertently disrupt systems, and intentional threats can be both targeted and untargeted attacks from a variety of threat sources. Sources of threats include criminal groups, hackers, terrorists, organization insiders, and foreign nations engaged in crime, political activism, or espionage and information warfare. These threat sources vary in terms of the capabilities of the actors, their willingness to act, and their motives, which can include monetary gain or political advantage, among others. Moreover, potential threat actors have a variety of attack techniques at their disposal, which can adversely affect computers, software, a network, an organizations operation, an industry, or the Internet itself. The nature of cyber attacks can vastly enhance their reach and impact due to the fact that attackers do not need to be physically close to their victims and can more easily remain anonymous, among other things. The magnitude of the threat is compounded by the ever-increasing sophistication of cyber attack techniques, such …

401(k) Plans: Increased Educational Outreach and Broader Oversight May Help Reduce Plan Fees
A letter report issued by the Government Accountability Office with an abstract that begins "Plan sponsors and participants paid a range of fees for services, though smaller plans typically paid higher fees as a percentage of plan assets. For example, the average amount sponsors of small plans reported paying for recordkeeping and administrative services was 1.33 percent of assets annually, compared with 0.15 percent paid by sponsors of large plans. Larger plans were more likely to pass recordkeeping fees along to participants, but when fees were passed along to participants in small plans, those in large plans paid lower fees than those in small plans. Participants also paid for investment and plan consulting feesthrough fees deducted from their plan assetsin more instances than sponsors."

Space Acquisitions: DOD Is Overcoming Long-Standing Problems, but Faces Challenges to Ensuring Its Investments Are Optimized
Testimony issued by the Government Accountability Office with an abstract that begins "Most of the Department of Defense's (DOD) major satellite programs are in mature phases of development, that is, the initial satellites have been designed, fabricated, and launched into orbit while additional satellites of the same design are being produced. For the portfolio of major satellite programs, new cost and schedule growth is not as widespread as it was in prior years, but DOD is still experiencing problems. For example, total program costs have increased approximately $180 million from a baseline of $4.1 billion for one of two satellite programs that are in the earlier phases of acquisition. Though satellite programs are not experiencing problems as widespread as in years past, ground control systems and user terminals in most of DOD's major space system acquisitions are not optimally aligned, leading to underutilized satellites and limited capability provided to the warfighter. For example, the development and fielding of user terminals for a Navy communications satellite program lag behind the launch of new satellites by more than a year. Additionally, the development of ground software needed to extract capabilities of new missile warning satellites is not expected to be complete until …

Strategic Petroleum Reserve: Improving the Cost-Effectiveness of Filling the Reserve
Testimony issued by the Government Accountability Office with an abstract that begins "The Strategic Petroleum Reserve (SPR) was created in 1975 to help protect the U.S. economy from oil supply disruptions and currently holds about 700 million barrels of crude oil. The Energy Policy Act of 2005 directed the Department of Energy (DOE) to increase the SPR storage capacity from 727 million barrels to 1 billion barrels, which it plans to accomplish by 2018. Since 1999, oil for the SPR has generally been obtained through the royalty-in-kind program, whereby the government receives oil instead of cash for payment of royalties on leases of federal property. The Department of Interior's Minerals Management Service (MMS) collects the royalty oil and transfers it to DOE, which then trades it for oil suitable for the SPR. As DOE begins to expand the SPR, past experiences can help inform future efforts to fill the reserve in the most cost-effective manner. In that context, GAO's testimony today will focus on: (1) factors GAO recommends DOE consider when filling the SPR, and (2) the cost-effectiveness of using oil received through the royalty-in-kind program to fill the SPR. To address these issues, GAO relied on its 2006 report …

Coalition Warfare: Gulf War Allies Differed in Chemical and Biological Threats Identified and in Use of Defensive Measures
A letter report issued by the General Accounting Office with an abstract that begins "GAO confirmed differences among the United States, the United Kingdom, and France in the rates at which illnesses have been reported among their Gulf War veterans; their assessment of nuclear, biological, and chemical threats in the Gulf; and their preparations to meet them. However, because of differences in the experiences of the three sets of veterans, there is no single, unambiguous cause that can be identified for the reported illnesses. If multinational allies are to act in a coordinated fashion, they require a similar level of awareness of and preparation for the threats to be faced; otherwise, force protection and operational success could be jeopardized and the utility of some forces restricted. Gulf War Coalition members prepared for somewhat different threats and used different countermeasures. In addition, the U.S. lacked clear doctrine for timely and systematic warning of allied forces and U.S. ground troops about pending strikes on suspected nuclear, biological, and chemical targets."
