Sodium Fluozirconate Precipitation Process for Zirconium Fuels. Part 1. Laboratory Development
Precipitation, evaporation, and extraction feed preparation conditions are established for the removal of zirconium and fluoride from fuel dissolver product solutions by the addition of sodium formate. A sparingly soluble complex fluozirconate is formed. Ninety-five to 99% of the zirconium and fluoride is separated from the uranium losses of 0.1% or less. Chemical material balances, based on experimental data, were developed for two flowsheets. In one flowsheet, sufficient nitric acid is added to the combined wash solution and filtrate produced during the precipitation step to destroy the formate ion (which inhibits uranium extraction) and to prevent post-precipitation during the evaporation of these solutions. The other flowsheet calls for addition of sufficient nitric acid to destroy the formate ion, but not enough to prevent post- precipitation during the concentration step. Post-precipitation removes additional zirconium and fluoride, but necessitates an additional solids- separation step. (auth)

Demonstration of innovative applicatiions of technology for cost reductions to the CT-121 FGD process
The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

Weld Penetration and Defect Control
Highly engineered designs increasingly require the use of improved materials and sophisticated manufacturing techniques. To obtain optimal performance from these engineered products, improved weld properties and joint reliability are a necessarily. This requirement for improved weld performance and reliability has led to the development of high-performance welding systems in which pre-programmed parameters are specified before any welding takes place. These automated systems however lack the ability to compensate for perturbations which arise during the welding process. Hence the need for systems which monitor and control the in-process status of the welding process. This report discusses work carried out on weld penetration indicators and the feasibility of using these indicators for on-line penetration control.

Safety Calculations for MsSRE
A number of conceivable reactivity accidents were analyzed, using conservatively pessimistic assumptions and approximations, to permit evaluation of reactor safety. Most of the calculations, which are described in detail, were performed by a digital kinetics program, MURGATROYD. Some analog analyses were also made. None of the accidents which were analyzed lead to catastrophic failure of the reactor, which is the primary consideration. Some internal damage to the reactor from undesirably high temperatures could result from extreme cold- slug accidents, premature criticality during filling, or uncontrolled rod withdrawal. Each of these accidents could happen only by compounded failure of protective devices, and in each case there exists means of effective corrective action independent of the primary protection, so that damage is unlikeIy. The calculated response to arbitrary ramp and step additions of reactivity show that damaging pressures could occur only if the addition is the equivalent of a step of about 1% delta k/k or greater.

Evaluation of selected chemical processes for production of low-cost silicon. Phase III. Eighteenth quarterly progress report, January 1-March 31, 1980
Progress during this report period was marked by the initial operation of the Process Development Unit at about 50% of design capacity with indications that many aspects of the facility operated satisfactorily. However, a downstream constriction, the cause of which is being isolated, led to termination of the run after one-half hour of operation. In the light of observations made during earlier start-up efforts, several modifications of equipment and technique were made for improved operation. Vacuum outgassing experiments (850 to 1100/sup 0/C, 1 to 256 h) were carried out on miniplant-produced granules containing 360 and 3900 ppMw of zinc in the deposited silicon. Treatment of the data so that it can be extrapolated to the expected product of the Experimental Process System Development Unit awaits development of an appropriate model.

Emerging materials for solar cell applications: electrodeposited CdTe. Final report, February 14, 1979-February 14, 1980
Thin film gold/polycrystalline cadmium telluride Schottky solar cells made by electrodepositing the semiconductor on an ITO-coated glass substrate serving also as an ohmic contact demonstrated an internal efficiency of 4% over 2 mm/sup 2/ areas. During the year being reported upon, Monosolar devoted mator attention to refining the electroplating process and determining the parameters governing CdTe film stoichiometry, grain size, substrate adhesion, and quality. UCLA acting as a Monosolar sub-contractor characterized both the CdTe films themselves and solar cells made from them. Techniques were developed for making measurements on films often less than 1 micron in thickness. The highest values achieved for efficiency parameters, not necessarily all in the same cell, were V/sub oc/ = 0.5 V, J/sub sc/ = 11 mA/cm/sup 2/, and fill factor = 0.55 before corrections in the absence of anti-reflection coatings. Typical resistivities for n-CdTe films were 10/sup 5/ ..cap omega..-cm. Lifetimes of about 10/sup -10/ sec were measured. Absorption coefficient of these films is in the order of 10/sup 4/ for lambda < 0.7 ..mu..m. Measured energy gap for these CdTe films is 1.55 eV, sightly higher than the 1.45 eV value for single crystal CdTe. The activation energy of the dominating trap level …

Operations plan for the Regional Seismic Test Network
The Regional Seismic Test Network program was established to provide a capability for detection of extremely sensitive earth movements. Seismic signals from both natural and man-made earth motions will be analyzed with the ultimate objective of accurately locating underground nuclear explosions. The Sandia National Laboratories, Albuquerque, has designed an unattended seismic station capable of recording seismic information received at the location of the seismometers installed as part of that specific station. A network of stations is required to increase the capability of determining the source of the seismic signal and the location of the source. Current plans are to establish a five-station seismic network in the United States and Canada. The Department of Energy, Nevada Operations Office, has been assigned the responsibility for deploying, installing, and operating these remote stations. This Operation Plan provides the basic information and tasking to accomplish this assignment.

Business Systems Modernization: DOD Continues to Improve Institutional Approach, but Further Steps Needed
A letter report issued by the Government Accountability Office with an abstract that begins "For decades, the Department of Defense (DOD) has not been successful in repeated attempts to modernize its timeworn business systems and operations. In 1995, we first designated DOD's business systems modernization as "high risk," and we continue to designate it as such today. As our research on successful public and private sector organizations has shown, attempting a large-scale systems modernization program in a large organization such as DOD without, among other things, a well-defined enterprise architecture and the associated investment management controls for implementing it often results in systems that are duplicative, stovepiped, non-integrated, and unnecessarily costly to manage, maintain, and operate. In May 2001, we made recommendations to the Secretary of Defense that provided the means for effectively developing and implementing an enterprise architecture and limiting systems investments until the department had a well-defined architecture and a corporate approach to investment control and decision making. In July 2001, the department initiated a business management modernization program to, among other things, develop a business enterprise architecture and establish the investment controls needed to effectively implement it. This effort was begun as part of the Secretary of …

DOD Business Systems Modernization: Progress in Establishing Corporate Management Controls Needs to Be Replicated Within Military Departments
A letter report issued by the Government Accountability Office with an abstract that begins "In 1995, GAO first designated the Department of Defense's (DOD) business systems modernization program as "high risk," and GAO continues to do so today. To assist in addressing this high-risk area, the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005 contains provisions that are consistent with prior GAO investment management and enterprise architecture-related recommendations, and requires the department to submit annual reports to its congressional committees on its compliance with these provisions. The act also directs GAO to review each annual report. In response, GAO assessed the actions taken by DOD to comply with requirements of the act. To do so, GAO leveraged its recent reports on various aspects of the department's modernization management controls, and it reviewed, for example, the latest version of its business enterprise architecture and the associated transition plan and architecture federation strategy. GAO also interviewed key officials."

Military Housing Privatization: DOD Faces New Challenges Due to Significant Growth at Some Installations and Recent Turmoil in the Financial Markets
A letter report issued by the Government Accountability Office with an abstract that begins "In response to challenges the Department of Defense (DOD) was facing to repair, renovate, and construct military family housing, Congress enacted the Military Housing Privatization Initiative in 1996. The initiative enables DOD to leverage private sector resources to construct or renovate family housing. As of March 2009, DOD had awarded 94 projects and attracted over $22 billion in private financing. DOD plans to privatize 98 percent of its domestic family housing through 2012. Since GAO's last housing privatization report in 2006, major force structure initiatives have placed new demands on DOD for housing. GAO was asked to assess (1) the progress of DOD's housing privatization program, (2) the occupancy rates of the housing projects, (3) the impact of various force structure initiatives and DOD's efforts to mitigate any challenges, and (4) the effect of financial market turmoil on some projects. To perform this work, GAO visited 13 installations with privatization projects; analyzed project performance data; and interviewed DOD officials, real estate consultants, and private developers."

Mass Transit: Issues Related to Providing Dedicated Funding for the Washington Metropolitain Area Transit Authority
A letter report issued by the Government Accountability Office with an abstract that begins "A regional panel estimated that the Washington Metropolitan Area Transit Authority (WMATA)--Washington, D.C.'s, transit system--will have total budgetary shortfalls of $2.4 billion over 10 years. The panel and others have noted that WMATA's lack of a significant dedicated revenue source may affect its ability to keep the system in good working order. Proposed federal legislation would make $1.5 billion available to WMATA if the local governments established dedicated funding. This report addresses (1) the characteristics of dedicated funding and its effects on transit agencies and governments; (2) how potential revenue sources compare in terms of stability, adequacy, and other factors; (3) major actions needed to establish dedicated funding for WMATA and the progress made to date; and (4) issues that dedicated funding poses for the region and WMATA. To address these issues, GAO reviewed financial data for the nation's 25 largest transit agencies, interviewed officials from 6 transit agencies and from the state and local governments that support WMATA, and reviewed literature on the financing of mass transit. GAO provided a draft of this report to WMATA and the Department of Transportation for review. Officials from …

Defense Headquarters: DOD Needs to Periodically Review and Improve Visibility Of Combatant Commands' Resources
A letter report issued by the Government Accountability Office with an abstract that begins "GAO's analysis of resources devoted to the Department of Defense's (DOD) geographic combatant commands shows that authorized military and civilian positions and mission and headquarters-support costs have grown considerably over the last decade due to the addition of two new commands and increases in authorized positions at theater special operations commands. Data provided by the commands shows that authorized military and civilian positions increased by about 50 percent from fiscal years 2001 through 2012, to about 10,100 authorized positions. In addition, mission and headquarters support-costs at the combatant commands more than doubled from fiscal years 2007 through 2012, to about $1.1 billion. Both authorized military and civilian positions and mission and headquarters-support costs at the service component commands supporting the combatant commands also increased. Data on the number of personnel performing contract services across the combatant commands and service component commands varied or was unavailable, and thus trends could not be identified."

Credit and Debit Cards: Federal Entities Are Taking Actions to Limit Their Interchange Fees, but Additional Revenue Collection Cost Savings May Exist
A letter report issued by the Government Accountability Office with an abstract that begins "Federal entities--agencies, corporations, and others--are growing users of credit and debit cards, as both "merchants" (receiving payments) and purchasers. Merchants accepting cards incur fees--called merchant discount fees--paid to banks to process the transactions. For Visa and MasterCard transactions, a large portion of these fees-- referred to as interchange--goes to the card-issuing banks. Some countries have acted to limit these fees. GAO was asked to examine (1) the benefits and costs associated with federal entities' acceptance of cards, (2) the effects of other countries' actions to limit interchange fees, and (3) the impact on federal entities of using cards to make purchases. Among other things, GAO analyzed fee data and information on the impact of accepting and using cards from the Department of the Treasury (Treasury) and the General Services Administration, reviewed literature, and interviewed officials of major card companies and three foreign governments."
