ORR Operations for Period April 1961 to April 1962
A summary of the activities in the 4th operational year is presented for the ORR. On-stream time at 30 Mw was relatively steady with 75.4 and 83.7% representing the lowest and highest quarters. Modification of the ball-latch mechanism of the shim-rod-drives is in progress. The primary cooling system bypass control valve was modified and a d-c pony motor was added at the No. 3 primary pump. This addition was made to increase the reliability of adequate water flow for afterheat cooling. A study of coreboiling detection is being conducted. (J.R.D.)

Development of a solar-desiccant dehumidifier. Phase II second technical progress report
The solar desiccant air conditioner (SODAC) system and its operation are described, including the characteristics of the major components, the performance at design conditions, and the control schemes for optimum operation in various climates. The system uses granular silica gel as a desiccant. It may operate in either a recirculated mode (no air exchange between the outside and the conditioned space) or a ventilated mode (air exchanged between outside and conditioned space). The test data in the ventilated mode at design flow rates are presented. Data include outdoor and indoor inlet wet and dry bulb temperatures, indoor outlet dry and wet bulb temperatures, capacity, coefficient of performance, air flow rates, hot water temperature, and solar heat used. The effects of indoor, outdoor, and hot water temperatures on the capacity and coefficient of performance are shown graphically, and the recirculated and ventilated modes, performances are compared.

EVALUATION OF ULTIMATE DISPOSAL METHODS FOR LIQUID AND SOLID RADIOACTIVE WASTES. PART II. CONVERSION TO SOLID BY POT CALCINATION
The costs of pot calcination of Purex and Thorex wastes were calculated. The wastes were assumed produced by a plant processing 1500 ton/year of U converter fuel at a burnup of 10,000 Mwd/ton and 270 ton/year of Th converter fuel at 20,000 Mwd/ton. Costs were calculated for processing Purex waste in acidic and reacidified forms and for processing Thorex wastes in acidic and reacidified forms and with constituents added for producing an acidic Thorex glass. Calcination vessel designs were right circular cylinders similar to those used in engineering development studies. Costs were calculated for processing in 6-, 12-, and 24-in.-dia vessels with a fixed length of 10 ft. Vessel costs used, based on estimates from private industry, were calculated for wastes decayed 120 days and 1, 3, 10, and 30 years after reactor discharge prior to calcination. Aging had negligible effect on costs, except as it permitted larger diameter vessels to be used, because vessel and operating costs were much larger than capital costs in all cases. The lowest cost was 0.87 x 10/sup -2/ mill/kwh/sub e/ for processing acidic Purex and Thorex wastes in 24-in.-dia vessels, and the highest was 5.0 x 10/sup -2/ mill/kwh/sub e/ for processing reacidified …

Electroweak symmetry breaking: Higgs/whatever
In the first of these two lectures the Higgs mechanism is reviewed in its most general form, which does not necessarily require the existence of Higgs bosons. The general consequences of the hypothesis that electroweak symmetry breaking is due to the Higgs mechanism are deduced just from gauge invariance and unitarity. In the second lecture the general properties are illustrated with three specific models: the Weinberg-Salam model, its minimal supersymmetric extension, and technicolor. The second lecture concludes with a discussion of the experiment signals for strong WW scattering, whose presence or absence will allow us to determine whether the symmetry breaking sector lies above or below 1 TeV. 57 refs.

Information on Recent Default and Foreclosure Trends for Home Mortgages and Associated Economic and Market Developments
Correspondence issued by the Government Accountability Office with an abstract that begins "Substantial growth in the mortgage market in recent years has helped many Americans become homeowners. However, as of the latest quarterly data available, June 2007, more than 1 million mortgages were in default or foreclosure, an increase of 50 percent compared with June 2005. Defaults and foreclosures on home mortgages can impose significant costs on borrowers, lenders, mortgage investors, and neighborhoods. Additionally, recent increases in defaults and foreclosures have contributed to concern and increased volatility in certain U.S. and global financial markets. These developments have raised questions about the extent and causes of problems in the mortgage market. To provide some insights on these issues, Congress asked GAO to analyze (1) the scope and magnitude of recent default and foreclosure trends, and how these trends compare with historical values, and (2) developments in economic conditions and the primary and secondary mortgage markets associated with these trends."

Information Technology Dashboard: Opportunities Exist to Improve Transparency and Oversight of Investment Risk at Select Agencies
A letter report issued by the Government Accountability Office with an abstract that begins "Chief Information Officers (CIO) at six federal agencies rated the majority of their information technology (IT) investments as low risk, and many ratings remained constant over time. Specifically, CIOs at the selected agencies rated a majority of investments listed on the federal IT Dashboard as low risk or moderately low risk from June 2009 through March 2012; at five of these agencies, these risk levels accounted for at least 66 percent of investments. These agencies also rated no more than 12 percent of their investments as high or moderately high risk, and two agencies (Department of Defense (DOD) and the National Science Foundation (NSF)) rated no investments at these risk levels. Over time, about 47 percent of the agencies' Dashboard investments received the same rating in every rating period. For ratings that changed, the Department of Homeland Security (DHS) and Office of Personnel Management (OPM) reported more investments with reduced risk when initial ratings were compared with those in March 2012; the other four agencies reported more investments with increased risk. In the past, the Office of Management and Budget (OMB) reported trends for risky IT …

Warfighter Support: Independent Expert Assessment of Army Body Armor Test Results and Procedures Needed Before Fielding
A letter report issued by the Government Accountability Office with an abstract that begins "The Army has issued soldiers in Iraq and Afghanistan personal body armor, comprising an outer protective vest and ceramic plate inserts. GAO observed Preliminary Design Model testing of new plate designs, which resulted in the Army's awarding contracts in September 2008 valued at a total of over $8 billion to vendors of the designs that passed that testing. Between November and December 2008, the Army conducted further testing, called First Article Testing, on these designs. GAO is reporting on the degree to which the Army followed its established testing protocols during these two tests. GAO did not provide an expert ballistics evaluation of the results of testing. GAO, using a structured, GAO-developed data collection instrument, observed both tests at the Army's Aberdeen Test Center, analyzed data, and interviewed agency and industry officials to evaluate observed deviations from testing protocols. However, independent ballistics testing expertise is needed to determine the full effect of these deviations."

Information Technology: FBI Has Largely Staffed Key Modernization Program, but Strategic Approach to Managing Program's Human Capital Is Needed
A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Bureau of Investigation (FBI) recently began a 6-year, $425 million program called Sentinel to replace and expand on both its failed Virtual Case File (VCF) project and its antiquated, paper-based, legacy system for supporting mission-critical intelligence analysis and investigative case management activities. Because of the FBI's experience with VCF and the importance of Sentinel, GAO was requested to address a number of program management issues associated with acquiring Sentinel via a prime development contractor. This report focuses on one of these issues: whether the FBI is adequately providing for the program's human capital needs. The findings are based on GAO's review of relevant program documentation, interviews with program officials, and human capital management guidance."

Critical Infrastructure Protection: Progress Coordinating Government and Private Sector Efforts Varies by Sectors' Characteristics
A letter report issued by the Government Accountability Office with an abstract that begins "As Hurricane Katrina so forcefully demonstrated, the nation's critical infrastructures and key resources have been vulnerable to a wide variety of threats. Because about 85 percent of the nation's critical infrastructure is owned by the private sector, it is vital that the public and private sectors work together to protect these assets. The Department of Homeland Security (DHS) is responsible for coordinating a national protection strategy including formation of government and private sector councils as a collaborating tool. The councils, among other things, are to identify their most critical assets, assess the risks they face, and identify protective measures, in sector-specific plans that comply with DHS's National Infrastructure Protection Plan (NIPP). GAO examined (1) the extent to which these councils have been established; (2) the key facilitating factors and challenges affecting the formation of the councils; and (3) the overall status of the plans and key facilitating factors and challenges encountered in developing them. GAO obtained information by reviewing key documents and conducting interviews with federal and private sector representatives. GAO is not making any recommendations at this time since prior recommendations are still being implemented. …

VA and Defense Health Care: Progress and Challenges DOD Faces in Executing a Military Medical Surveillance System
A statement of record issued by the General Accounting Office with an abstract that begins "The Departments of Defense (DOD) and Veterans Affairs (VA) are establishing a medical surveillance system for the health care needs of military personnel and veterans. The system will collect and analyze information on deployments, environmental health threats, disease monitoring, medical assessments, and medical encounters. GAO has identified weaknesses in DOD's medical surveillance capability and performance during the Gulf War and Operation Joint Endeavor. Investigations into the unexplained illnesses of Gulf War veterans uncovered many deficiencies in DOD's ability to collect, maintain, and transfer accurate data on the movement of troops, potential exposures to health risks, and medical incidents during deployment. DOD has several initiatives under way to improve the reliability of deployment information and to enhance its information technology capabilities, though some initiatives are several years away from full implementation. The VA's ability to serve veterans and provide backup to DOD in times of war will be enhanced as DOD increases its medical surveillance capability."

Energy-Water Nexus: Improvements to Federal Water Use Data Would Increase Understanding of Trends in Power Plant Water Use
A letter report issued by the Government Accountability Office with an abstract that begins "In 2000, thermoelectric power plants accounted for 39 percent of total U.S. freshwater withdrawals. Traditionally, power plants have withdrawn water from rivers and other water sources to cool the steam used to produce electricity, so that it may be reused to produce more electricity. Some of this water is consumed, and some is discharged back to a water source. In the context of growing demands for both water and electricity, this report discusses (1) approaches to reduce freshwater use by power plants and their drawbacks, (2) states' consideration of water use when reviewing proposals to build power plants, and (3) the usefulness of federal water data to experts and state regulators. GAO reviewed federal water data and studies on cooling technologies. GAO interviewed federal officials, as well as officials from seven selected states."

Department of Education: Status of Financial Management Weaknesses Reported in the Fiscal Year 1999 Financial Statement Audit
Correspondence issued by the General Accounting Office with an abstract that begins "This correspondence discusses financial weaknesses reported in the Department of Education's fiscal year 1999 financial statement audit. A major area needing improvement involves internal controls, which provide the framework for the accomplishment of management objectives, accurate financial reporting, and compliance with laws and regulations. This lack of good internal controls puts Education at risk of waste, fraud, abuse, and mismanagement. Corrective actions undertaken by Education in response to the identified weaknesses indicate that it is making progress in working towards financial accountability. These corrective actions include purchasing a new general ledger system, acquiring a software tool to help automate the reconciliation process, improving computer controls, and establishing a process to transfer certain excess Federal Family Education Loan Program funds to the Treasury. The effectiveness of the corrective actions will be determined as part of the fiscal year 2000 financial statement audit."

Information Technology: Agencies Need to Strengthen Oversight of Billions of Dollars in Operations and Maintenance Investments
A letter report issued by the Government Accountability Office with an abstract that begins "Federal agency assessments of the performance of information technology (IT) investments in operations and maintenance (O&M)--commonly referred to as operational analyses (OAs)--vary significantly. Office of Management and Budget (OMB) guidance calls for agencies to develop an OA policy and perform such analyses annually to ensure steady state investments continue to meet agency needs. The guidance also includes 17 key factors (addressing areas such as cost, schedule, customer satisfaction, and innovation) that are to be assessed. The five agencies GAO reviewed varied in the extent to which they carried out these tasks."

Regulatory Takings: Agency Compliance with Executive Order on Government Actions Affecting Private Property Use
Testimony issued by the General Accounting Office with an abstract that begins "Each year federal agencies issue numerous proposed or final rules or take other regulatory actions that may potentially affect the use of private property. Some of these actions may result in the property owner being owed just compensation under the Fifth Amendment. In 1988 the President issued Executive Order 12630 on property rights to ensure that government actions affecting the use of private property are undertaken on a well-reasoned basis with due regard for the potential financial impacts imposed on the government. This testimony is based on our recent report on the compliance of the Department of Justice and four agencies--the Department of Agriculture, the Army Corps of Engineers, the Environmental Protection Agency, and the Department of the Interior--with the executive order. (Regulatory Takings: Implementation of Executive Order on Government Actions Affecting Private Property Use, GAO-03-1015, Sept.19,2003). Specifically, GAO examined the extent to which (1)Justice has updated its guidelines for the order to reflect changes in case law and issued supplemental guidelines for the four agencies, (2) the four agencies have complied with the specific provisions of the executive order, and (3) just compensation awards have been assessed …

Environmental Protection Agency: Use of Precautionary Assumptions in Health Risk Assessments and Benefits Estimates
A letter report issued by the General Accounting Office with an abstract that begins "Some of the Environmental Protection Agency's (EPA) regulations set standards that limit environmental contaminants to levels that are determined, in large part, on the basis of the health risks they pose. When EPA assesses the health risks of contaminants, however, the agency is faced with uncertainties and gaps in scientific knowledge and data. This report summarizes GAO's findings on whether EPA's benefits estimates for major environmental regulations that establish health-based standards reflect precautionary assumptions about health risks. Three key factors influence EPA's use of precautionary assumptions in assessing health risks. First, EPA is influenced by its mission to protect human health and safeguard the natural environment. Second, EPA is influenced by the nature and extent of relevant data. Finally, EPA is influenced by the nature of the health risk being evaluated."

Telecommunications: Characteristics and Competitiveness of the Internet Backbone Market
A letter report issued by the General Accounting Office with an abstract that begins "Although most Americans are familiar with Internet service providers that give consumers a pathway, or "on-ramp," to the Internet, few are familiar with Internet backbone providers and backbone networks. At the Internet's core are many high-capacity, long-haul "backbone" networks that route data traffic over long distances using high-speed fiber lines. Internet backbone providers compete in the marketplace and cooperate in the exchange of data traffic. The cooperative exchange of traffic among backbone providers is essential if the Internet is to remain a seamless and widely accessible public medium. Interconnection among Internet backbone providers varies both in terms of the physical structure and financial agreements of data traffic exchange. The physical structure of interconnection takes two forms: (1) the exchange of traffic among many backbone providers at a "network access point"--a common facility--and (2) the exchange of traffic between two or more backbone providers at "private" interconnection points. No publicly available data exist with which to evaluate competitiveness in the Internet backbone market. Evolution of this market is likely to be largely affected by two types of emerging services. First, demand is likely to rise for time-sensitive …
