The 75As(n,2n) Cross Sections into the 74As Isomer and Ground State

Description: The {sup 75}As(n, 2n) cross section for the population of the T{sub 1/2} = 26.8-ns isomer at E{sub x} = 259.3 keV in {sup 74}As has been measured as a function of incident neutron energy, from threshold to E{sub n} = 20 MeV. The cross section was measured using the GEANIE spectrometer at LANSCE/WNR. For convenience, the {sup 75}As(n, 2n) population cross section for the {sup 74}As ground state has been deduced as the difference between the previously-known (n, 2n) reaction cross section and the newly measured {sup 75}As(n, 2n){sup 74}As{sup m} cross section. The (n, 2n) reaction, ground-state, and isomer population cross sections are tabulated in this paper.

ADVANCED VITRIFICATION SYSTEM (RIC AVS) RESEARCH AND DEVELOPMENT PROJECT

Description: The objective of this AVS testing program is to use bench-scale test equipment to produce a vitrified product at maximum waste loading from the specified AZ-101 waste simulant and conduct a TTT analysis using laboratory scale melts to show compliance with the DOE Waste Acceptance Product Specifications for Vitrified High-Level Waste Forms (WAPS). The vitrified product complies with the following WAPS. A borosilicate glass with a waste loading of 60.9-wt% was produced from a slurry feed of AZ101 simulant. Glass durability testing, glass characterization testing, and testing methodology were performed in accordance with the Department of Energy approved Test Plan. The glass has two crystalline phases and good uniformity of composition. The Product Consistency Test on the 6 location-specific samples are at least 1 to 2 orders of magnitude below the mean PCT results for the EA glass. Standard deviations were less than 10% of measured values. The glass transition temperature averaged 658 {+-} 9 C. A TTT diagram was produced. There was measured cesium loss of about 2%, and compliance with the Universal Treatment Standards.

ALARA Review of the Spallation Neutron Source Accumulator Ring and Transfer Lines

Description: The Spallation Neutron Source (SNS) is designed to meet the growing need for new tools that will deepen our understanding in materials science, life science, chemistry, fundamental and nuclear physics, earth and environmental sciences, and engineering sciences. The SNS is an accelerator-based neutron-scattering facility that when operational will produce an average beam power of 2 MW at a repetition rate of 60 Hz. The accelerator complex consists of the front-end systems, which will include an ion source; a 1-GeV full-energy linear accelerator; a single accumulator ring and its transfer lines; and a liquid mercury target. This report documents an as-low-as-reasonably-achievable (ALARA) review of the accumulator ring and transfer lines at their early design stage. An ALARA working group was formed and conducted a review of the SNS ring and transfer lines at the {approx}25% complete design stage to help ensure that ALARA principles are being incorporated into the design. The radiological aspects of the SNS design criteria were reviewed against regulatory requirements and ALARA principles. Proposed features and measures were then reviewed against the SNS design criteria. As part of the overall review, the working group reviewed the design manual; design drawings and process and instrumentation diagrams; the environment, safety, and health manual; and other related reports and literature. The group also talked with SNS design engineers to obtain explanations of pertinent subject matter. The ALARA group found that ALARA principles are indeed being incorporated into the early design stage. Radiation fields have been characterized, and shielding calculations have been performed. Radiological issues are being adequately addressed with regard to equipment selection, access control, confinement structure and ventilation, and contamination control. Radiation monitoring instrumentation for worker and environment protection are also being considered--a good practice at this early design stage. The ring and transfer lines are being designed for hands-on …

Application of Inorganic Membrane Technology to Hydrogen-hydrocarbon Separations

Description: Separation efficiency for hydrogen/light hydrocarbon mixtures was examined for three inorganic membranes. Five binary gas mixtures were used in this study: H{sub 2}/CH{sub 4} , H{sub 2}/C{sub 2}H{sub 6}, H{sub 2}/C{sub 3}H{sub 8}, He/CO{sub 2}, and He/Ar. The membranes examined were produced during a development program at the Inorganic Membrane Technology Laboratory in Oak Ridge and provided to us for this testing. One membrane was a (relatively) large-pore-diameter Knudsen membrane, and the other two had much smaller pore sizes. Observed separation efficiencies were generally lower than Knudsen separation but, for the small-pore membranes, were strongly dependent on temperature, pressure, and gas mixture, with the most condensable gases showing the strongest effect. This finding suggests that the separation is strongly influenced by surface effects (i.e., adsorption and diffusion), which enhance the transport of the heavier and more adsorption-prone component and may also physically impede flow of the other component. In one series of experiments, separation reversal was observed (the heavier component preferentially separating to the low-pressure side of the membrane). Trends showing increased separation factors at higher temperatures as well as observations of some separation efficiencies in excess of that expected for Knudsen flow suggest that at higher temperatures, molecular screening effects were observed. For most of the experiments, surface effects were stronger and thus apparently overshadow molecular sieving effects.

ASSESSMENT OF HYDROCARBON SEEPAGE DETECTION METHODS ON THE FORT PECK RESERVATION, NORTHEAST MONTANA

Description: Surface exploration techniques have been employed in separate study areas on the Fort Peck Reservation in northeastern Montana. Anomalies associated with hydrocarbon seepage are documented in all three areas and a variety of surface exploration techniques can be compared. In a small area with established production, Head Gas and Thermal Desorption methods best match production; other methods also map depletion. In a moderate-size area that has prospects defined by 3D seismic data, Head Gas along with Microbial, Iodine, and Eh soil anomalies are all associated with the best hydrocarbon prospect. In a large area that contains many curvilinear patterns observed on Landsat images, that could represent micro-seepage chimneys, results are inconclusive. Reconnaissance mapping using Magnetic Susceptibility has identified a potential prospect; subsequent Soil Gas and Head Gas surveys suggest hydrocarbon potential. In the final year of this project the principle contractor, the Fort Peck Tribes, completed a second survey in the Wicape 3D Seismic Prospect Area (also known as Area 6 in Phase I of the project) and sampled several Landsat image features contained in the Smoke Creek Aeromag Anomaly Area (also known as Area 1 in Phase II of the project). Methods determined to be most useful in Phases I and II, were employed in this final Phase III of the study. The Southwest Wicape seismic anomaly was only partially confirmed. The abundant curvilinears proposed to be possible hydrocarbon micro-seepage chimneys in the Smoke Creek Area were not conclusively verified as such. Insufficient sampling of background data precludes affirmative identification of these mostly topographic Landsat features as gas induced soil and vegetation anomalies. However relatively higher light gas concentrations were found associated with some of the curvilinears. Based on the findings of this work the Assiniboine & Sioux Tribes of the Fort Peck Reservation intend to utilize surface hydrocarbon …

Bioactive glass coatings for orthopedic metallic implants

Description: The objective of this work is to develop bioactive glass coatings for metallic orthopedic implants. A new family of glasses in the SiO2-Na2O-K2O-CaO-MgO-P2O5 system has been synthesized and characterized. The glass properties (thermal expansion, softening and transformation temperatures, density and hardness) are in line with the predictions of established empirical models. The optimized firing conditions to fabricate coatings on Ti-based and Co-Cr alloys have been determined and related to the glass properties and the interfacial reactions. Excellent adhesion to alloys has been achieved through the formation of 100-200 nm thick interfacial layers (Ti5Si3 on Ti-based alloys and CrOx on Co-Cr). Finally, glass coatings, approximately 100 mu m thick, have been fabricated onto commercial Ti alloy-based dental implants.

A Cavity Ring-Down Spectroscopy Mercury Continuous Emission Monitor Progress Report

Description: Previous work on the detection of mercury using the cavity ring-down (CRD) technique has concentrated on the detection and characterization of the desired mercury transition. Interferent species present in flue gas emissions have been tested as well as a simulated flue gas stream. Additionally, work has been done on different mercury species such as the elemental and oxidized forms. The next phase of the effort deals with the actual sampling system. This sampling system will be responsible for acquiring a sample stream from the flue gas stack, taking it to the CRD cavity where it will be analyzed and returning the gas stream to the stack. In the process of transporting the sample gas stream every effort must be taken to minimize any losses of mercury to the walls of the sampling system as well as maintaining the mercury in its specific state (i.e. elemental, oxidized, or other mercury compounds). SRD first evaluated a number of commercially available sampling systems. These systems ranged from a complete sampling system to a number of individual components for specific tasks. SRD engineers used some commercially available components and designed a sampling system suited to the needs of the CRD instrument. This included components such as a pyrolysis oven to convert all forms of mercury to elemental mercury, a calibration air source to ensure mirror alignment and quality of the mirror surfaces, and a pumping system to maintain the CRD cavity pressure from atmospheric pressure (760 torr) down to about 50 torr. SRD also began evaluating methods for the CRD instrument to automatically find the center of a mercury transition. This procedure is necessary as the instrument must periodically measure the baseline losses of the cavity off of the mercury resonance and then return to the center of the transition to accurately measure the …

Child Support Enforcement: New Reforms and Potential Issues

Description: P.L. 104-193 (the 1996 welfare reform legislation) made major changes to the Child Support Enforcement (CSE) program. Some of the changes include requiring states to increase the percentage of fathers identified, establishing an integrated, automated network linking all states to information about the location and assets of parents, and requiring states to implement more enforcement techniques to obtain collections from debtor parents. Additional legislative changes were made in 1997, 1998, and 1999, but not in 2000, 2001, or 2002. This report describes several aspects of the revised CSE program and discusses three issues that probably will be reexamined by the 108th Congress — CSE financing, parental access by noncustodial parents, and distribution of support payments.

The Confederated Tribes of the Warm Springs Indian Reservation of Oregon John Day Basin Office : Watershed Restoration Projects : 2002 Annual Report.

Description: The John Day is the nation's second longest free-flowing river in the contiguous United States and the longest containing entirely unsupplemented runs of anadromous fish. Located in eastern Oregon, the basin drains over 8,000 square miles, Oregon's fourth largest drainage basin, and incorporates portions of eleven counties. Originating in the Strawberry Mountains near Prairie City, the John Day River flows 284 miles in a northwesterly direction, entering the Columbia River approximately four miles upstream of the John Day dam. With wild runs of spring Chinook salmon and summer steelhead, westslope cutthroat, and redband and bull trout, the John Day system is truly a basin with national significance. The majority of the John Day basin was ceded to the Federal government in 1855 by the Confederated Tribes of the Warm Springs Reservation of Oregon (Tribes). In 1997, the Tribes established an office in the basin to coordinate restoration projects, monitoring, planning and other watershed activities on private and public lands. Once established, the John Day Basin Office (JDBO) formed a partnership with the Grant Soil and Water Conservation District (GSWCD), also located in the town of John Day, who contracts the majority of the construction implementation activities for these projects from the JDBO. The GSWCD completes the landowner contact, preliminary planning, engineering design, permitting, construction contracting, and construction implementation phases of most projects. The JDBO completes the planning, grant solicitation/defense, environmental compliance, administrative contracting, monitoring, and reporting portion of the program. Most phases of project planning, implementation, and monitoring are coordinated with the private landowners and basin agencies, such as the Oregon Department of Fish and Wildlife and Oregon Water Resources Department. In 2002, the JDBO and GSWCD proposed continuation of their successful partnership between the two agencies and basin landowners to implement an additional twelve (12) watershed conservation projects.

Crowtm Process Application for Sites Contaminated With Light Non-Aqueous Phase Liquids and Chlorinated Hydrocarbons

Description: Western Research Institute (WRI) has successfully applied the CROWTM (Contained Recovery of Oily Wastes) process at two former manufactured gas plants (MGPs), and a large wood treatment site. The three CROW process applications have all occurred at sites contaminated with coal tars or fuel oil and pentachlorophenol (PCP) mixtures, which are generally denser than water and are classified as dense non-aqueous phase liquids (DNAPLs). While these types of sites are abundant, there are also many sites contaminated with gasoline, diesel fuel, or fuel oil, which are lighter than water and lie on top of an aquifer. A third site type occurs where chlorinated hydrocarbons have contaminated the aquifer. Unlike the DNAPLs found at MGP and wood treatment sites, chlorinated hydrocarbons are approximately one and a half times more dense than water and have fairly low viscosities. These contaminants tend to accumulate very rapidly at the bottom of an aquifer. Trichloroethylene (TCE) and perchloroethylene, or tetrachloroethylene (PCE), are the major industrial chlorinated solvents that have been found contaminating soils and aquifers. The objective of this program was to demonstrate the effectiveness of applying the CROW process to sites contaminated with light non-aqueous phase liquids (LNAPLs) and chlorinated hydrocarbons. Individual objectives were to determine a range of operating conditions necessary to optimize LNAPL and chlorinated hydrocarbon recovery, to conduct numerical simulations to match the laboratory experiments and determine field-scale recoveries, and determine if chemical addition will increase the process efficiency for LNAPLs. The testing consisted of twelve TCE tests; eight tests with PCE, diesel, and wood treatment waste; and four tests with a fuel oil-diesel blend. Testing was conducted with both vertical and horizontal orientations and with ambient to 211 F (99 C) water or steam. Residual saturations for the horizontal tests ranged from 23.6% PV to 0.3% PV. Also conducted was …

Defense Acquisitions: Matching Resources with Requirements Is Key to the Unmanned Combat Air Vehicle Program's Success

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) is developing a new unmanned combat air vehicle (UCAV) that can suppress enemy air defenses and conduct other air-to-ground attacks, particularly against heavily defended targets. Because it may perform these missions at a relatively low cost, the UCAV could be used to replace some of DOD's aging tactical aircraft fleet. A key to UCAV's success will lie in DOD's ability to match users' needs, or requirements, with the developer's resources (technology and design knowledge, money, and time) when product development begins. Our work shows that doing so can prevent rework and save both time and money. Therefore, we assessed DOD's ability to make this match. GAO conducted its work on the basis of the Comptroller General's authority and addresses the report to the Subcommittee on Tactical Air and Land Forces, House Committee on Armed Services because of its interest and jurisdiction in the program."

The Effect of Applied Pressure During Feeding of Critical Cast Aluminum Alloy Components With Particular Reference to Fatigue Resistance

Description: the medium to long freezing range alloys of aluminum such as A356, A357, A206, 319 for example are known to exhibit dispersed porosity, which is recognized as a factor affecting ductility, fracture toughness, and fatigue resistance of light alloy castings. The local thermal environment, for example, temperature gradient and freezing from velocity, affect the mode of solidification which, along with alloy composition, heat treatment, oxide film occlusion, hydrogen content, and the extent to which the alloy contracts on solidification, combine to exert strong effects on the porosity formation in such alloys. In addition to such factors, the availability of liquid metal and its ability to flow through the partially solidified casting, which will be affect by the pressure in the liquid metal, must also be considered. The supply of molten metal will thus be controlled by the volume of the riser available for feeding the particular casting location, its solidification time, and its location together with any external pressure that might be applied at the riser.

Employment of OMHAR Staff at HUD Following Their Employment at OMHAR

Description: Correspondence issued by the General Accounting Office with an abstract that begins "To reduce the estimated multibillion-dollar costs to the federal government of renewing rental subsidy contracts while helping preserve available and affordable low-income rental housing, Congress passed the Multifamily Assisted Housing Reform and Affordability Act of 1997 (Act), which established the "mark-to market" program to restructure the contracts. The Act also created the Office of Multifamily Housing Assistance Restructuring (OMHAR) as a temporary organization within the Department of Housing and Urban Development (HUD) to administer the contract-restructuring program. With OMHAR scheduled to "sunset" (cease operations) on September 30, 2001, the Subcommittee on Housing and Transportation, Committee on Banking, Housing, and Urban Affairs, held a hearing in June 2001 to determine whether it would be more advantageous to the federal government to extend rather than end the program. Subsequently, Congress extended the sunset date to September 30, 2004, with restructuring work at HUD continuing until 2006. To ensure that OMHAR could attract and retain staff with requisite expertise in multifamily housing finance issues, the Act provided the Director of OMHAR authority to pay salaries comparable with the Federal Deposit Insurance Corporation. As a result, OMHAR salaries are generally higher than those paid for most federal positions. OMHAR is staffed in part by former HUD employees, and also by former employees of other federal agencies and the private sector. GAO agreed to (1) describe what information HUD and OMHAR officials provided regarding OMHAR staff employment at HUD following their employment at OMHAR; (2) describe how HUD determined to which OMHAR employees it would offer employment and what their pay levels would be; and (3) determine, for eligible OMHAR employees, how accepting HUD's offer would affect their pay."

Field Demonstration of Carbon Dioxide Miscible Flooding in the Lansing-Kansas City Formation, Central Kansas Progress Report

Description: Progress is reported for the period from April 1, 2003 to June 30, 2003. The pilot water injection plant became operational 4/18/03 and began long-term injection in the CO2I No.1 on 4/23/03. The CO2I No.1 exhibits sufficient injectivity for pilot requirements with average absolute permeability surrounding this well equal to {approx}85 millidarcies. Response to injection in the CO2I No.1 has established that conductivity between CO2I No.1 and CO2 No.12, No.10, No.18 and TB Carter No.5 is sufficient for the demonstration. Workovers of the CO2 No.16 and CO2 No.13 were completed in April and May, respectively. Pressure response indicates No.16 communicates with the flood pattern area but core, swab-test, and pressure response data indicate permeability surrounding No.16 is not adequate to maintain the production rates needed to support the original pattern as the well is presently completed. Decisions concerning possible further testing and stimulation have been postponed until after testing of the No.13 is complete. Production rates for the No.13 are consistent with a surrounding reservoir average absolute permeability of {approx}80 md. However, pressure and rate tests results, partially due to the nature of the testing conducted to date, have not confirmed the nature of the CO2I No.1-CO2 No.13 conductivity. A build-up test and conductivity test are planned to begin the first weeks of the next quarter to obtain reservoir properties data and establish the connectivity and conductivity between CO2 I-1 and CO2 No.13. A new geomodel of the pattern area has been developed based on core from No.16 and the new wireline logs from the No.10, No.12, No.16, and No.13. The new geomodel is currently being incorporated into the basic calculations of reservoir volume and flood design and predicted response as well as the reservoir simulators. Murfin signed a letter agreement with FLOCO2 of Odessa, TX for supply of CO2 …

Fundamental Studies of the Durability of Materials for Interconnects in Solid Oxide Fuel Cells, Volume 1

Description: This report describes the result of the first eight months of effort on a project directed at improving metallic interconnect materials for solid oxide fuel cells (SOFCs). The results include cyclic oxidation studies of a group of ferritic alloys, which are candidate interconnect materials. The exposures have been carried out in simulated fuel cell atmospheres. The oxidation morphologies have been characterized and the ASR has been measured for the oxide scales. The effect of fuel cell electric current density on chromia growth rates has been considered The thermomechanical behavior of the scales has been investigated by stress measurements using x-ray diffraction and interfacial fracture toughness measurements using indentation. The ultimate goal of this thrust is to use knowledge of changes in oxide thickness, stress and adhesion to develop accelerated testing methods for evaluating SOFC interconnect alloys. Finally a theoretical assessment of the potential for use of ''new'' metallic materials as interconnect materials has been conducted and is presented in this report. Alloys being considered include materials based on pure nickel, materials based on the ''Invar'' concept, and coated materials to optimize properties in both the anode and cathode gases.

Hanford Supplemental Waste Processing Technologies - Fiscal Year 2003 Recommendations for Selective Dissolution Studies and Radioactive Waste Preparation

Description: This document describes two tasks that support CH2M Hill Hanford Group's (CHG) Mission Acceleration Initiative (MAI) testing and demonstration/deployment of supplemental technologies, but the tasks are not to be part of the vendor's scope. The vendor's will be provided samples of radioactive waste for their testing. This document describes the preparation of the radioactive waste samples. CHG is responsible to retrieve the saltcake waste from the single-shell tanks and expects to dissolve the waste using water dissolution. When water dissolves the waste the more soluble components of the waste (including cesium) will dissolve first, leaving the lesser soluble components of the waste in the tank. This phenomenon, termed selective dissolution, is expected to provide a partial separation of cesium from the waste. This document also describes a program involving tank dissolution demonstrations, modeling, and laboratory testing to more completely understand how the composition of the retrieved salt cake waste will change during the course of retrieval.
