Hydraulic tests were made on the Hallam Prototype Free-Surface Sodium Pump to determine the net positive suction head (NPSH) required at various sodium flow rates. Pump performance data were also collected. The results indicate that an NPSH of 22 ft sodium is required at the design flow rate of 7200 gpm at approximates 1000 deg F, agreeing with computed values, and that the pump is designed with a safety margin of slightly over l0%. (D.L.C.)

The design requirements, design philosophy, method and assumptions, and preliminary computer-aided design of the Near-Term Hybrid Vehicle including its electric and heat power units, control equipment, transmission system, body, and overall vehicle characteristics are presented. (LCL)

Run 25 was the final period of power operational of the HRT. The reactor was operated for periods of 62, 8, 52, and 80 hours at 5 Mw with no outward indication of fuel and core and blanket average temperatures of 270 and 230 deg C, respectively. The uranium concentration in the was 1.7 to 2.0 g U/kg D/sub 2/O. Longer periods of operation were prevented by mechanical difficulties, notably with the fuel feed pump. While the reactor was subcritical after the last of the above runs, the upper patch in the core tank wall became dislodged, allowing greater core-to-blanket mixing. The resultant blanket uranium concentration was 2.9 g U/kg D/sub 2/O. The reactor was subsequently operated at April 28, 1961. The experiment was operated at high temperature for a total of 10,866 hours. The system was critical for a total of 8,841 hours and produced 16,295 Mwhours of power. The fuel, heavy water, and some corrosion specimens were recovered, and the reactor was stored in an assembled state. (auth)

A seven- to twenty-fold volume reduction can be obtained from fluidized bed calcination of aqueous aluminum nitrate wastes, depending on the operating conditions employed and their effect on the intra-panticle porosity and absolute density of the calcined alumina. Among the calcining variables, only the bed temperature and the fuel aluminum concentration had a significant effect on the intra-particle porosity of alumina generated during studies conducted primarily in a two-foot-square fluidized bed calciner. A quantitative correlation of the effect of these variables is presented. Alumina with an intra-particle porosity as low as five per cent can be generated by employing a suitable combination of low bed temperature and dilute aluminum feed concentration. Feed sodium concentration and product alpha alumina content were found to have minor effect on intra-particle porosity. Results also show that an inverse relationship exists between the nitrate content of the calcine and the calcination temperature. (auth)

This Interim Report summarizes the findings of our first twenty in-depth interviews in the Advanced Nuclear Reactor Public Opinion Project. We interviewed 6 industry trade association officials, 3 industry attorneys, 6 environmentalists/nuclear critics, 3 state officials, and 3 independent analysts. In addition, we have had numerous shorter discussions with various individuals concerned about nuclear power. The report is organized into the four categories proposed at our April, 1991, Advisory Group meeting: safety, cost-benefit analysis, science education, and communications. Within each category, some change of focus from that of the Advisory Group has been required, to reflect the findings of our interviews. This report limits itself to describing our findings. An accompanying memo draws some tentative conclusions.

This document basically represents a comparison between theory and practice of capacity-expansion planning in the electric-utility industry. The purpose of the comparison is to provide avenues for further exploration in utility decision making. The focus of the Phase II study is upon the role of uncertainty in the decision-making process. The Phase I effort was directed at modeling the Averch-Johnson theory of the regulated utility. Part I of this report reviews the Anderson study (D. Anderson, Models for Determining Least-Cost Investments in Electricity Supply). The Anderson paper has become a standard reference for capacity-planning studies in the electric-utility industry. Part II examines uncertainty and the behavior of the firm. Part III reviews 5 models of electric-utility capacity planning under uncertainty, and Part IV is concerned with capacity-planning models in practice.

The effect of modifying the dislocation structure by room-temperature prestraining on the subsequent yielding behavior at 77 deg K is being studied. Results on tantalum single crystals indicated that a considerable decrease in the early yield stress for a given strain is effected by prestraining at room temperature. Twinning was observed in the tantalum at 77 deg K and normal rates of strain. It is shown that the potential barrler to dislocation motion in crystalline solids can be measured in relatively pure bcc transition metals such as Nb, Ta, Mo, and W. Work is being carried out to extend the method of differential calorimetry to measurements of stored-energy-release spectra in deformed bcc metals. Measurements for copper are discussed. (M.C.G.)

As part of the CAD-CAM development project, this report discusses the mathematics underlying the program QUADRIC, which does computations on objects modeled as Boolean combinations of quadric half-spaces. Topics considered include projective space, quadric surfaces, polars, affine transformations, the construction of solids, shaded image, the inertia tensor, moments, volume, surface integrals, Monte Carlo integration, and stratified sampling. 1 figure.

Near stoichiometric bulk polycrystalline CdSiAs/sub 2/ has been synthesized by two techniques: (1) direct fusion of the elements and (2) direct fusion of the binaries SiAs, Cd/sub 3/As/sub 2/ and CdAs/sub 2/. The latter technique resulted in denser ternary material with good homogeneity. The above binaries melt congruently and were also formed by direct fusion. Sputtered ternary films were formed using a bulk CdSiAs/sub 2/ target, and a composite target of CdAs/sub 2/ discs in a Si plate. Composition of the CdSiAS/sub 2/ target changed with sputtering time. Amorphous films deposited from that target were heat treated, and became crystalline and near stoichiometric but with poor mechanical properties. It appears that films deposited from the composite target (Si + CdAs/sub 2/) can be adjusted to stoichiometry by means of sputtering power and target geometry. As deposited, these films also were amorphous. With respect to evaporated films, the study of thermal decomposition of CdSiAs/sub 2/ in vacuum was completed. The decomposition is preferential toward Cd between 570/sup 0/ and 710/sup 0/C, and toward As in the 710 to 1010/sup 0/C range. It is concluded that evaporation of the ternary is not a suitable method for forming CdSiAs/sub 2/ films. Plans for …

A letter report issued by the Government Accountability Office with an abstract that begins "As a group, Asian American and Pacific Islanders represent about 5 percent of the U.S. population and hold about 8 percent of the college degrees. To better understand the educational attainment and average incomes of the subgroups that comprise this population, the Committee asked: 1) What are Asian American and Pacific Islander subgroups' educational attainment and household income levels? (2) What challenges, if any, Asian American and Pacific Islander students face in pursuing and completing their post-secondary education? and (3) What federal and institutional resources do institutions with large Asian American and Pacific Islander student enrollment use to address the particular needs of these students? GAO analyzed data from the U.S. Census Bureau and the U.S. Department of Education (Education) and spoke with officials and Asian American and Pacific Islander students at eight postsecondary institutions."

A letter report issued by the Government Accountability Office with an abstract that begins "During the Cold War, the Department of Energy (DOE) produced nuclear materials for nuclear weapons at its Savannah River Site (SRS) by dissolving highly radioactive spent nuclear fuel from reactors in a facility known as H-Canyon. DOE planned to end H-Canyon operations in 2007 but now plans to continue H-Canyon operations until 2019 to process additional nuclear material. GAO was asked to (1) identify the types of nuclear materials DOE will process using H-Canyon and its associated costs of operation, (2) determine whether SRS's radioactive waste storage tanks and associated nuclear waste facilities are capable of handling the additional waste generated by H-Canyon, and (3) describe H-Canyon's compliance with safety and environmental requirements. To conduct its work, GAO reviewed DOE's plans to process nuclear material using H-Canyon and visited SRS to observe the canyon and associated radioactive waste treatment facilities."

A letter report issued by the Government Accountability Office with an abstract that begins "The majority of the Department of Veterans Affairs (VA) education payments were made to a small percentage of schools receiving VA funding in fiscal year 2011, primarily through the Post-9/11 GI Bill. About 5 percent of schools (654 schools) received more than $3.8 billion in aggregate VA education payments used for tuition and fees in fiscal year 2011, over 60 percent of such funding. These 654 "highly VA-funded schools" each received at least $2 million (and as much as $113 million) in Post-9/11 GI Bill tuition and fee payments from fiscal year 2010 through fiscal year 2011 and enrolled more total students on average than other schools. Almost half of tuition and fee payments for all VA education programs were used at public schools. However, the breakdown of Post-9/11 GI Bill payments differed somewhat, with for-profit and public schools receiving about the same proportion of Post-9/11 GI Bill tuition and fee payments."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government owns facilities that are underutilized in locations where it also leases space. In some cases, space within these government-owned properties could be occupied by other government agencies. This is particularly true for the U.S. Postal Service (USPS), for which declining mail volume and operational changes have freed space in many facilities. However, this potential for collocation of federal agencies is affected by such factors as the size, location, and condition of the available space."

A letter report issued by the Government Accountability Office with an abstract that begins "Voluntary agencies consider various factors when determining where refugees will be placed, but few agencies we visited consulted relevant local stakeholders, which posed challenges for service providers. When deciding how many refugees to place in each community, some voluntary agencies prioritize local agency capacity, such as staffing levels, while others emphasize community capacity, such as housing availability. Although the Immigration and Nationality Act states that it is the intent of Congress for voluntary agencies to work closely with state and local stakeholders when making these decisions, the Department of State's Bureau of Population, Refugees, and Migration (PRM) offers limited guidance on how this should occur. Some communities GAO visited had developed formal processes for obtaining stakeholder input after receiving an overwhelming number of refugees, but most had not, which made it difficult for health care providers and school systems to prepare for and properly serve refugees."

A letter report issued by the General Accounting Office with an abstract that begins "About 7,000 Peace Corps volunteers now serve in 70 countries, often living in areas with limited access to reliable communications, police, or medical services. Moreover, as Americans, they may be viewed as relatively wealthy and hence good targets for criminal activity. The Peace Corps has reported rising numbers of assaults against its volunteers since it began collecting data in 1990. However, the Peace Corps' record is mixed when it comes to developing safe and secure housing and worksites for volunteers, monitoring volunteers and responding to security concerns or criminal incidents, and preparing for emergencies. To reduce risks to its volunteers, the Peace Corps has adopted policies that address monitoring and disseminating information on the security environment; volunteer training; development of safe and secure housing and work sites for volunteers; monitoring volunteers and responding to incidents and concerns; and planning for emergencies, such as evacuations. Volunteer surveys and GAO visits to five overseas ports indicate that volunteers are generally satisfied with agency training programs and other efforts designed to emphasize safety and security awareness. The agency is not certain, but officials have stated that efforts to improve …

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Army's acquisition of Category 2 weapons systems."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) operates 37 laboratories to provide the scientific foundation for its mission. Over the past 20 years, independent evaluations have identified problems with the laboratories' operations and management and called for improved planning, coordination, and leadership, as well as consolidation of laboratories. In its 2012 budget, EPA requested $2 million for another independent study of its laboratories. GAO was asked to examine the extent to which EPA (1) has addressed the findings of prior independent evaluations; (2) uses an agencywide, coordinated approach to manage its laboratory infrastructure and whether its new study will achieve stated cost savings and laboratory improvement goals; and (3) uses a comprehensive planning process to manage its laboratory workforce. GAO reviewed agency documents and independent evaluations, visited EPA laboratories, interviewed agency officials, and examined agency databases."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the U.S. Strategic Command, the Department of Defense (DOD) is in the midst of a global cyberspace crisis as foreign nation states and other actors, such as hackers, criminals, terrorists, and activists exploit DOD and other U.S. government computer networks to further a variety of national, ideological, and personal objectives. This report identifies (1) how DOD is organized to address cybersecurity threats; and assesses the extent to which DOD has (2) developed joint doctrine that addresses cyberspace operations; (3) assigned command and control responsibilities; and (4) identified and taken actions to mitigate any key capability gaps involving cyberspace operations. It is an unclassified version of a previously issued classified report. GAO analyzed policies, doctrine, lessons learned, and studies from throughout DOD, commands, and the services involved with DOD's computer network operations and interviewed officials from a wide range of DOD organizations.."
