STEAM-COOLED POWER REACTOR EVALUATION, STEAM-COOLED FAST BREEDER REACTOR
Conceptual design and economic studies of a steamcooled fast breeder reactor that can also be used as a source of power are presented. Two reactor plant sizes were considered: a 300-Mw(e) central power station plant and a 40 Mw(e) plant. It was concluded that attractive economics and good breeding characteristics breeding ratios from 1.27 to 1.42) can be achieved in steam- cooled PuO/sub 2/UO/sub 2/ fueled fast reactors. Low capital costs can be obtained by a compact reactor core and the absence of large heat exchangers and complicated process systems. Reactor design data are discussed. Analysis showed that these reactors can be prevented from going prompt critical, when fully flooded, by incorporating a tolerable amount of high resonance absorption materials such as hafnium or indium. An increase in reactivity on loss of coolant was indicated by preliminary calculations. (M.C.G.)

Energy conservation by hyperfiltration: food industry background literature survey
The application of hyperfiltration to selected food product streams and food processing wastewaters for energy conservation was examined. This literature survey had led to the following conclusions: no research has been conducted in the food industry using membranes with hot process streams due to the temperature limitation (< 40/sup 0/C) of the typically studied cellulose acetate membranes; based on the bench-scale research reviewed, concentration of fruit and vegetable juices with membranes appears to be technically feasible; pretreatment and product recovery research was conducted with membranes on citrus peel oil, potato processing and brine wastewaters and wheys. The experiments demonstrated that these applications are feasible; many of the problems that have been identified with membranes are associated with either the suspended solids or the high osmotic pressure and viscosity of many foods; research using dynamic membranes has been conducted with various effluents, at temperatures to approx. 100/sup 0/C, at pressures to 1200 psi and with suspended solids to approx. 2%; and, the dynamic membrane is being prototype tested by NASA for high temperature processing of shower water. The literature review substantiates potential for dynamic membrane on porous stainless tubes to process a number of hot process and effluent streams in the …

Incorporation of high-level wastes in SYNROC: results from recent process-engineering studies at Lawrence Livermore National Laboratory
In this paper, highlights from recent engineering research and development, in particular, results from fluidized bed calcination studies of SYNROC slurry are summarized. A schematic diagram of the envisioned SYNROC process (at this stage of development) is also presented. It shows the use of a fluidized bed calciner to prepare SYNROC powder that is then fed to a storage hopper. Bellows-type canisters are filled, evacuated, sealed and preheated. The preheated canisters are loaded into a hot isotactic pressing unit where they are densified, then removed and cooled and finally loaded into a waste storage container. After sealing, this container is decontaminated and transferred to the interim storage facility and then, ultimately, to an underground repository.

Characterization of Open-Cycle Coal-Fired MHD Generators. Quarterly Technical Summary Report No. 3, January 1--March 31, 1977. [Negative Ion Formation, Electron/Slag Interaction, and Alkali/Slag Interaction]
The purpose of this contract effort is to understand how nonfuel components of coal will affect the electron and alkali seed chemistry in a high temperature coal combustion system like that envisioned for direct fired MHD generators. Three specific problems are being considered during this contract period. The first problem area is to characterize the formation of negative ions due to electron attachment processes in the combustion flow. While some stable negative ions may be formed from hydrocarbon combustion species (OH/sup -/), the bulk of the stable negative ions are expected to be formed from oxidized inorganic coal slag constituents (BO/sup -//sub 2/, PO/sup -//sub 2/, AlO/sup -//sub 2/, etc). Negative ion formation can reduce the conductivity of the MHD plasma, particularly at the low temperature end of the MHD channel, thus decreasing the efficiency of power generation. The second problem area involves the role slag condensation may play in determining the electron density through recombination, also adversely affecting conductivity in the core flow. The competitive balance between thermionic emission from slag droplets and electron/ion recombination on the droplet surfaces may be severely tipped in favor of electron loss processes, depending on the slag properties. The third problem area is …

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts
During this period, we focused our attention in analyzing the magnetic nature of the extensively used trimetallic catalyst system Cu-Co-Cr for the production of higher alcohols. We believe that there could be some correspondence between the catalytic and magnetic behaviors of the transition metal catalyst systems. Both the morphology and metallic charge distribution of the particles are know to govern the catalytic as well as the magnetic properties of the system. Based on this concept, we have extensively examined the Cu/Co system varying Cu/Co ratio from 0.2--4.0. Spectroscopic results are outlined herein. (VC)

Lasers in chemical processing
The high cost of laser energy is the crucial issue in any potential laser-processing application. It is expensive relative to other forms of energy and to most bulk chemicals. We show those factors that have previously frustrated attempts to find commercially viable laser-induced processes for the production of materials. Having identified the general criteria to be satisfied by an economically successful laser process and shown how these imply the laser-system requirements, we present a status report on the uranium laser isotope separation (LIS) program at the Lawrence Livermore National Laboratory (LLNL).

Traffic Safety Data: State Data System Quality Varies and Limited Resources and Coordination Can Inhibit Further Progress
A letter report issued by the Government Accountability Office with an abstract that begins "Traffic crashes kill or injure millions of people each year. High-quality traffic safety data is vital to allocate resources and target programs as the Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA) and states work to improve traffic safety through data-driven approaches. To qualify for federal funding, states must submit plans which include fatality and crash data analyses to identify areas for improvement. This requested report provides information on (1) the extent to which state traffic safety data systems meet NHTSA performance measures for assessing the quality of data systems, and (2) progress states have made in improving traffic safety data systems, and related challenges. To conduct this work, GAO analyzed state traffic records assessments, visited eight states, and interviewed federal officials and other traffic safety experts."

Maritime Security: New Structures Have Improved Information Sharing, but Security Clearance Processing Requires Further Attention
A letter report issued by the Government Accountability Office with an abstract that begins "Sharing information with nonfederal officials is an important tool in federal efforts to secure the nation's ports against a potential terrorist attack. The Coast Guard has lead responsibility in coordinating maritime information sharing efforts. The Coast Guard has established area maritime security committees--forums that involve federal and nonfederal officials who identify and address risks in a port. The Coast Guard and other agencies have sought to further enhance information sharing and port security operations by establishing interagency operational centers--command centers that tie together the efforts of federal and nonfederal participants. GAO was asked to review the efforts to see what impact the committees and interagency operational centers have had on improving information sharing and to identify any barriers that have hindered information sharing."

National Environmental Policy Act: Little Information Exists on NEPA Analyses
A letter report issued by the Government Accountability Office with an abstract that begins "Governmentwide data on the number and type of most National Environmental Policy Act (NEPA) analyses are not readily available, as data collection efforts vary by agency. NEPA generally requires federal agencies to evaluate the potential environmental effects of actions they propose to carry out, fund, or approve (e.g., by permit) by preparing analyses of different comprehensiveness depending on the significance of a proposed project's effects on the environment—from the most detailed Environmental Impact Statements (EIS) to the less comprehensive Environmental Assessments (EA) and Categorical Exclusions (CE). Agencies do not routinely track the number of EAs or CEs, but the Council on Environmental Quality (CEQ)—the entity within the Executive Office of the President that oversees NEPA implementation—estimates that about 95 percent of NEPA analyses are CEs, less than 5 percent are EAs, and less than 1 percent are EISs. Projects requiring an EIS are a small portion of all projects but are likely to be high-profile, complex, and expensive. The Environmental Protection Agency (EPA) maintains governmentwide information on EISs. A 2011 Congressional Research Service report noted that determining the total number of federal actions subject to NEPA …
