A letter report issued by the Government Accountability Office with an abstract that begins "The three key federal energy efficiency programs--minimum energy efficiency standards led by the Department of Energy (DOE), EnergyGuide led by the Federal Trade Commission (FTC), and Energy Star led by the Environmental Protection Agency (EPA) with support from DOE--take different approaches to the shared goal of improving the energy efficiency of selected categories of household appliances and consumer electronics. The scope of products covered by these three programs also varies, and a number of products are covered by only one program, while others are covered by two or all three. Examples are as follows:"

A letter report issued by the Government Accountability Office with an abstract that begins "The Office of Federal Procurement Policy (OFPP) sets standards and policies for the federal acquisition workforce, and has established certification requirements, including minimal training, for the three main acquisition roles--contracting staff, Contracting Officer's Representatives, and Program/Project Managers--to promote the development of government-wide core acquisition competencies and facilitate mobility across agencies. DOD follows separate certification standards. The Federal Acquisition Institute (FAI), which is responsible for fostering and promoting the training and development of the acquisition workforce, works closely with OFPP and has initiatives underway to improve the collection and management of training information, including cost data and course evaluations; streamline communication of acquisition training guidance; and coordinate efforts to leverage acquisition workforce training resources throughout the government."

A letter report issued by the Government Accountability Office with an abstract that begins "The most severely distressed multiemployer plans have taken significant steps to address their funding problems and, while most plans expected improved financial health, some did not. A survey conducted by a large actuarial and consulting firm serving multiemployer plans suggests that the large majority of the most severely underfunded plans--those designated as being in critical status--either have increased or will increase employer contributions or reduce participant benefits. In some cases, these measures will have significant effects on employers and participants. For example, several plan representatives stated that contribution increases had damaged some firms' competitive position in the industry, and, in some cases, threatened the viability of such firms. Similarly, reductions in certain benefits--such as early retirement subsidies--may create hardships for some older workers, such as those with physically demanding jobs. Most of the 107 surveyed plans expected to emerge from critical status, but about 25 percent did not and instead seek to delay eventual insolvency."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO identified three states—Maine, Montana, and Washington—that have developed pilot programs focused on replacing older manufactured homes using a combination of state and federal funds. The three programs were relatively small, accounting for about $4.5 million in spending and responsible for replacing 81 homes, over about 2 years. The programs differed in requirements, including whether the land that the replacement home would occupy had to be owned or could be leased; the types of financing used, with some replacements requiring recipients to take on a partial mortgage; and the types of replacement homes."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) 2012 portfolio of 86 major defense acquisition programs is estimated to cost a total of $1.6 trillion, reflecting decreases in both size and cost from the 2011 portfolio. Those decreases are largely the result of more programs exiting than entering the portfolio, as well as reductions in procurement quantities due to program cancelations and restructurings. Notably a majority of programs in the portfolio gained buying power in the last year as their acquisition unit costs decreased. DOD's 10 costliest programs, excluding the Missile Defense Agency's Ballistic Missile Defense System (BMDS), drive most of the portfolio's cost performance and funding needs. The majority (65 percent) of the funding that DOD estimates it will need to complete its current programs is associated with those 10 programs, and almost all of that funding is for procurement."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense’s (DOD) competition rate for all contract obligations declined over the past five fiscal years, from 62.6 percent in fiscal year 2008 to 57.1 percent in fiscal year 2012. GAO also found that the competition rate in fiscal year 2012 varied by specific DOD component with the Air Force having the lowest at 37.1 percent and the Defense Logistics Agency the highest at 83.3 percent. The majority of the noncompetitive awards cited the availability of only one responsible source to meet the government’s needs as the reason for using noncompetitive procedures."

A letter report issued by the Government Accountability Office with an abstract that begins "The California High-Speed Rail Authority (Authority) met some, but not all of the best practices in GAO's Cost Estimating and Assessment Guide (Cost Guide) for producing cost estimates that are accurate, comprehensive, well documented, and credible. By not following all best practices, there is increased risk of such things as cost overruns, missed deadlines, and unmet performance targets. The Authority substantially met the criteria for the accurate characteristic by, for example, the cost estimate's reflecting the current scope of the project. However, the Authority partially met the criteria for the other three characteristics since the operating costs were not sufficiently detailed (comprehensive), the development of some cost elements were not sufficiently explained (well documented), and because no systematic assessment of risk was performed (credible). The Federal Railroad Administration (FRA) issued limited guidance for preparing cost estimates, and this guidance did not reflect best practices in the Cost Guide. The Authority plans to improve its cost estimates."

A letter report issued by the Government Accountability Office with an abstract that begins "For the contracts GAO reviewed, the National Science Foundation (NSF) generally used key contracting practices in each of the three phases of the acquisition process, but the agency needs additional guidance on early acquisition planning as well as arrangements for contract audits."

A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal year 2008 to fiscal year 2012, the U.S. Export-Import Bank's (Ex-Im) outstanding financial commitments (exposure) grew from about $59 billion to about $107 billion, largely in long-term loans and guarantees. Factors associated with this growth include reduced private-sector financing following the financial crisis and Ex-Im's authorization of direct loans--a product not offered by export credit agencies in some other countries--to fill the gap in private-sector lending."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO found that airport operators, government officials, real estate developers, and other regional stakeholders are taking actions consistent with five factors when pursuing airport-centric development (development on the airport property to enhance the airport's nonaeronautical revenue and development outside the airport that leverages a region's proximity to the airport)."

Title 10 of the United States Code of Federal Regulations Part 71 for the Nuclear Regulatory Commission (10 CFR Part 71.73) requires that Type B radioactive material (RAM) packages satisfy certain Hypothetical Accident Conditions (HAC) thermal design requirements to ensure package safety during accidental fire conditions. Compliance with thermal design requirements can be met by prototype tests, analyses only or a combination of tests and analyses. Normally, it is impractical to meet all the HAC using tests only and the analytical methods are too complex due to the multi-physics non-linear nature of the fire event. Therefore, a combination of tests and thermal analyses methods using commercial heat transfer software are used to meet the necessary design requirements. The authors, along with his other colleagues at Savannah River National Laboratory in Aiken, SC, USA, have successfully used this 'tests and analyses' approach in the design and certification of several United States' DOE/NNSA certified packages, e.g. 9975, 9977, 9978, 9979, H1700, and Bulk Tritium Shipping Package (BTSP). This paper will describe these methods and it is hoped that the RAM Type B package designers and analysts can use them for their applications.

Hydrogen explosions may occur simultaneously with water hammer accidents in nuclear facilities, and a theoretical mechanism to relate water hammer to hydrogen deflagrations and explosions is presented herein. Hydrogen and oxygen generation due to the radiolysis of water is a recognized hazard in pipe systems used in the nuclear industry, where the accumulation of hydrogen and oxygen at high points in the pipe system is expected, and explosive conditions may occur. Pipe ruptures in nuclear reactor cooling systems were attributed to hydrogen explosions inside pipelines, i.e., Hamaoka, Nuclear Power Station in Japan, and Brunsbuettel in Germany. Prior to these accidents, an ignition source for hydrogen was not clearly demonstrated, but these accidents demonstrated that a mechanism was, in fact, available to initiate combustion and explosion. A new theory to identify an ignition source and explosion cause is presented here, and further research is recommended to fully understand this explosion mechanism.

This project attempted to deposit extremely thick and dense protective barrier onto a mirror film stack with a PET substrate. The target thickness was very high for thin film products; particularly since large areas and long production lengths of film are needed to make the final product economic. The technical investigations in this project centered on maintaining a quality barrier (i.e. dense film) while evaporating alumina with a high deposition rate onto a low cost PET substrate. The project found that the proposed configuration, particularly direct ion bombardment, provides too narrow a solution space to effectively and economically produce the ASRM attempted. The initial project goals were met when depositing on a limited width and at a modest rate. However, expanding to wide deposition at aggressive deposition rates did not produce consistent film quality. Economic viability drives the process to maximize deposition rate. The current system configuration has a limiting upper rate threshold that does not appear economically viable. For future work, alternate approaches seem needed to address the challenges encountered in the scale-up phase of this project.

Pacific Northwest National Laboratory initiated the application of the time-varying, one-dimensional sediment-contaminant transport code, TODAM (Time-dependent, One-dimensional, Degradation, And Migration) to simulate the cesium migration and accumulation in the Ukedo River in Fukushima. This report describes the preliminary TODAM simulation results of the Ukedo River model from the location below the Ougaki Dam to the river mouth at the Pacific Ocean. The major findings of the 100-hour TODAM simulation of the preliminary Ukedo River modeling are summarized as follows:
