  2. Fort St. Vrain performance

    International Nuclear Information System (INIS)

    Fort St. Vrain, on the system of Public Service Company of Colorado, is the only high temperature gas-cooled power reactor in the United States. This plant was designed by General Atomic Company and utilizes helium as the primary coolant. The core consists of triso-coated uranium and thorium fuel particles cast into cylinical rods within prismatic graphite blocks. The primary coolant system consists of the reactor, twelve steam generator modules, and four helium circulators contained within a prestressed concrete reactor vessel. The once-through steam generators provide high quality 1,000 deg. F, 2,400 psi main steam and 1,000 deg. F reheat steam to the main turbine. The plant has generated 3,334,000 MWH of electricity and has undergone 3 reactor refuelings. Many of the primary system components at Fort St. Vrain are proto-typical in nature and this plant has undergone an extensive and elaborate testing program. Difficulties primarily with the helium circulators and fuel element column movements particularly at high power levels have resulted in significant modifications. Power operation at 100% was achieved in late 1981 with a net thermal efficiency of nearly 39%. Excellent performance of the coated fuel particles has contributed to a full power circulating activity sixty times lower than the design with subsequent cleanliness throughout the plant. Except for 1985, when a combined total radiological exposure for all personnel reached 35 manrem due to the necessity to completely refurbish all of the control rod drive mechanisms, the average total combined exposure for each of the past five years was under 3 manrem. This exemplary radiological cleanliness has, with the exception of tritium, allowed Fort St. Vrain to consistently operate with noble gas airborne and liquid effluent releases more than an order of magnitude lower than the average for the U.S. nuclear power industry.

    The great archipelago in Indonesia with its wealthy and various nature, the products and commodities of tropic agriculture and the rich soil, was through the centuries a region of interest for other countries all over the world. For several reasons some of these countries came to Indonesia to establish their existence and tried to monopolize the trading. These countries such as the Portuguese, the Spanish, the Dutch and the British built strengthened trade stations which later became forts all over Indonesia to defend their interest. The archipelago of Indonesia possesses a great number of fortification-works as legacies of native rulers and those which were built by European trading companies and later became colonial powers in the 16th to the 19th centuries. These legacies include those specific structures built as a defence system during pre and within the period of World War II. These fortresses are nowadaysvaluable subjects, because they might be considered as shared heritage among these countries and Indonesia. It's important to develop a vision to preserve these particular subjects of heritage, because they are an interesting part of the Indonesian history and its cultural treasures. The Government of the Republic of Indonesia has national program to compile a comprehensive documentation of the existing condition of these various types of forts as cultural heritage. The result of the 3 years project was a comprehensive 442 forts database in Indonesia, which will be very valuable to the implementation of legal protection, preservation matters and adaptive re-use in the future.

  12. Fort St. Vrain decommissioning project

    International Nuclear Information System (INIS)

    Public Service Company of Colorado (PSCo), owner of the Fort St. Vrain nuclear generating station, achieved its final decommissioning goal on August 5, 1997 when the Nuclear Regulatory Commission terminated the Part 50 reactor license. PSCo pioneered and completed the world's first successful decommissioning of a commercial nuclear power plant after many years of operation. In August 1989, PSCo decided to permanently shutdown the reactor and proceed with its decommissioning. The decision to proceed with early dismantlement as the appropriate decommissioning method proved wise for all stake holders - present and future - by mitigating potential environmental impacts and reducing financial risks to company shareholders, customers, employees, neighboring communities and regulators. We believe that PSCo's decommissioning process set an exemplary standard for the world's nuclear industry and provided leadership, innovation, advancement and distinguished contributions to other decommissioning efforts throughout the world.

  20. Fort Hood solar energy project

    Energy Technology Data Exchange (ETDEWEB)

    1980-07-30

    During the period April 1975 to March 1978, the American Technological University (ATU) of Killeen, Texas, was awarded several follow-on contracts by the Division of Solar Energy (DSE), Energy Research and Development Administration (ERDA), which subsequently became the Division of Solar Technology (DST), Department of Energy (DOE). The contracts were to design a solar total energy system for use at Fort Hood, Texas. A review encompassing the period of the project from January 1975 to March 1978, was conducted by the Office of Inspector General (IG), DOE. The review examined both the management of the project by ATU and ERDA personnel and the award and administration by ERDA of the contracts to ATU for support of the project. The IG review found that: (1) there was a lack of continuity in the management of the project by both ATU and ERDA; (2) ERDA failed to maintain control of the project and failed to issue specific project direction to ATU; (3) ERDA failed to follow existing procurement regulations for the review and acceptance of unsolicited proposals from ATU; (4) the ERDA Headquarters program Manager and the Contract Administrator for the conceptual design phase of the project had failed to ensure that all the tasks which had been funded were performed by ATU; and (5) the decision by the Director, ERDA/DSE, to award successive contracts to ATU was questionable in view of ATU's performance on the project.

  2. Fort St. Vrain decommissioning experience

    International Nuclear Information System (INIS)

    Nuclear plant decommissioning represents a significant expenditure of time and resources for nuclear utilities. Public Service Company of Colorado (PSC) is in the process of completing the decommissioning of the Fort St. Vrain (FSV) Nuclear Station, the first large-scale commercial nuclear plant to be decommissioned under the U.S. Nuclear Regulatory Commission's (NRC's) 1988 decommissioning rule. PSC's experience has included dispositioning spent fuel, choosing a decommissioning alternative, and actively decommissioning the plant from dismantlement and decontamination through final survey. When the plant was prematurely shut down in August 1989, PSC's initial task was to find a storage location for FSV's spent fuel. PSC had a contract with the U.S. Department of Energy (DOE) to ship FSV spent fuel to the Idaho National Engineering Laboratory (INEL), and all previously removed spent fuel had been shipped there. However, Idaho legally blocked further FSV spent-fuel shipments to INEL, and PSC decided to license and build an on-site, passively cooled independent spent-fuel storage installation (ISFSI). By June 1992, all FSV spent fuel was transferred from the reactor building to the ISFSI. PSC has been able to use low-level radioactive waste (LLWR) disposal facilities in the Northwest Compact, and disposal costs are within estimates. Industrial and radiological safety have been emphasized throughout the project, and performance in these areas has been outstanding. PSC has obtained NRC Aprilproval of a final survey plan that allows for many of the plant's components and systems to remain in place, and final survey activities are nearing completion. PSC is in the process of repowering the facility with natural gas-fired combustion turbines and heat recovery boilers. The first combustion turbine was placed in service Ap 30, 1996

  10. Fort St. Vrain operations and future

    International Nuclear Information System (INIS)

    June 1989 resulted in the highest electric generation month in the history of the Fort St. Vrain plant. This culminated an excellent operating period involving the first half of 1988. The plant was then shutdown in July on a scheduled outage to make repairs in the main steam drive section of all of the helium circulators. This outage was significantly extended due to problems with moisture ingress into the primary coolant felt to be primarily from the core support floor section of the liner cooling system. 1989 also marks the 10th Anniversary of Fort St. Vrain as a commercial nuclear power plant. Electrical generation from this plant throughout this period has not been good, generally because of the prototypical nature of key plant components, primarily the helium circulators. Also, throughout this period there has been substantial increase in operations, maintenance, and fuel costs which could not be offset by the sale of electricity from the plant. This led to the decision to shutdown Fort St. Vrain permanently on or before June 30, 1990. The lessons learned and operational experiences from Fort St. Vrain have been substantial for the development of the Gas-Cooled Reactor Program and in achieving a safe, commercially viable plant design for the MHTGR. Superb fuel performance has not only provided a radiologically clean plant, but has achieved significant safety attributes in the licensing of the MHTGR. Equipment performance for Fort St. Vrain on key components and systems such as the steam generators, purification system control rod drives, and many others has been factored into the design of the MHTGR. Additional benefits are anticipated as the plant completes its operating phase and goes through defueling and decommissioning. As primary system components become available and are physically evaluated, further valuable data will be secured for the benefit of the MHTGR. (author)

    2004-01-01

    Invasive, non-native species of plants, animals, and disease organisms adversely affect the ecosystems they enter. Like "biological wildfires," they can quickly spread, and they affect nearly all terrestrial and aquatic ecosystems. Invasive species have become the greatest environmental challenge of the 21st century in terms of economic, environmental, and human health costs, with an estimated impact in the U.S. of over $138 billion per year. Managers of Department of the Interior and other public and private lands and waters rank invasive species as their top resource management problem. The Invasive Species Science Branch of the Fort Collins Science Center (FORT) provides research and technical assistance relating to invasive species management concerns, including understanding how these species are introduced, identifying areas vulnerable to invasion, forecasting invasions, and developing control methods. To disseminate this information, FORT scientists are developing the Invasive Species Information Node of the National Biological Information Infrastructure (NBII), a comprehensive, Web-accessible database of invasive plant and animal species and disease agents. From these data, and in partnership with Colorado State University, the National Aeronautic Space Administration (NASA), and others, FORT scientists are constructing models to understand and predict invasive species behavior for more effective management. FORT is also the administrative home of the National Institute of Invasive Species Science, a growing consortium of partnerships between government and private organizations established by the U.S. Geological Survey (USGS) and its many cooperators. The Institute was formed to develop cooperative approaches for invasive species science that meet the urgent needs of land managers and the public. Its mission is to work with others to coordinate data and research from many sources to predict and reduce the effects of harmful nonnative plants, animals, and

  13. Fort St. Vrain circulator operating experience

    International Nuclear Information System (INIS)

    Fort St. Vrain, on the system of Public Service Company of Colorado, is the only high-temperature gas-cooled power reactor in the United States. Four helium circulators are utilized in this plant to transfer heat from the reactor to the steam generators. These unique machines have a single stage axial flow helium compressor driven by a single stage steam turbine. A single stage water driven (pelton wheel) turbine is the back-up drive utilizing either feed water, condensate, or fire water as the driving fluid. Developmental testing of the circulators was accomplished prior to installation into Fort St. Vrain. A combined machine operating history of approximately 250,000 hours has shown these machines to be of conservative design and proven mechanical integrity. However, many problems have been encountered in operating the complex auxiliaries which are necessary for successful circulator and plant operation. It has been 15 years since initial installation of the circulators occurred at Fort St. Vrain. During this time, a number of significant issues had to be resolved dealing specifically with machine performance. These events include cavitation damage of the pelton wheels during the initial plant hot functional testing, cracks in the water turbine buckets and cervic coupling, static shutdown seal bellows failure, and, most recently, degradation of components within the steam drive assembly. Unreliable operation particularly with the circulator auxiliaries has been a focus of attention by Public Service Company of Colorado. Actions to replace or significantly modify the existing circulators and their auxiliaries are currently awaiting decisions concerning the long-term future of the Fort St. Vrain plant.

    International Nuclear Information System (INIS)

    The 330-MW(e) Fort St. Vrain reactor, built by General Atomic for the Public Service Company of Colorado, is the first commercial High-Temperature Gas-Cooled Reactor (HTGR) employing the multi-hole block-type fuel element design. Bringing the Fort St. Vrain HTGR to commercial operation is one of the major ongoing efforts at General Atomic. The Fort St. Vrain programme has progressed through construction, pre-operational testing and checkout of innumerable systems, fuel loading, initial criticality, and operational testing at power levels up to 2% rated power. Thus far, all major plant systems including the PCRV, circulators, and steam generators have demonstrated their performance adequacy during the tests performed to date. Extensive tests on the reactor core at zero power and up to 2% power have demonstrated the accuracy in the design predictions of core characteristics; measured nuclear parameters such as initial criticality, control system worths, neutron flux distributions, and temperature coefficients agreed extremely well with precalculated values. Gaseous fission product release measurements to date confirmed the extensive analytical estimates. Significant unforeseen schedule delays have centred around the control rod drives, circulator service water systems and problems arising from the introduction of large quantities of water into the primary system as well as from meeting all licensing requirements for electrical cable separation and seismic restraint systems for steam lines. To date, all tests necessary before the rise-to-full-power have been completed, and the rise-to-power programme is expected to be resumed again in the fall of 1975. The schedule delays which have arisen from mechanical, electrical, or operational problems had to be expected from the startup of a first-of-a-kind plant, but none of the problems has indicated any deficiencies with the unique advantages of the HTGR concept.

    Severe flooding occurred in northern Maine from April 28 to May 1, 2008, and damage was extensive in the town of Fort Kent (Lombard, 2010). Aroostook County was declared a Federal disaster area on May 9, 2008. The extent of flooding on both the Fish and St. John Rivers during this event showed that the current Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) (Federal Emergency Management Agency, 1979) were out of date. The U.S. Geological Survey (USGS) conducted a study to develop a flood inundation map library showing the areas and depths for a range of flood stages from bankfull to the flood of record for Fort Kent to complement an updated FIS (Federal Emergency Management Agency, in press). Hydrologic analyses that support the maps include computer models with and without the levee and with various depths of backwater on the Fish River. This fact sheet describes the methods used to develop the maps and describes how the maps can be accessed.

Preliminary low power and intermediate power tests have proved the design concept features and calculations and most of the components. Safe conditions following loss of coolant were confirmed. Release of radioactivity from the fuel was less than predicted up to 70% full power. Modifications and repairs caused delays and included, chiefly: Pelton wheel emergency cooling drives, helium circulator bearings, the pressure-regulating system for water lubricant in circulator bearings, liner cooling lines, removal of moisture from the vessel, electrical cable rerouting, helium seals around control rod drives, and a leak in one steam generator. Core temperature oscillation problems are being analyzed before passing the currently imposed 70% power level. Fort St. Vrain has demonstrated that the concept of a large HTGR system incorporating a prestressed concrete reactor vessel is sound. (author)

  1. Status of the Fort St. Vrain decommissioning

    International Nuclear Information System (INIS)

    Fort St. Vrain is a high temperature gas cooled reactor. It has been shut down as a result of financial and technical difficulties. Fort St. Vrain has been planning for defueling and decommissioning for at least three years. The preliminary decommissioning plan, in accordance with the NRC's final rule, has been submitted and is being reviewed by the NRC. The basis of the preliminary decommissioning plan has been SAFSTOR. Public Service Company, who is the owner and operator of FSV, is scheduled to submit a proposed decommissioning plan to the NRC in the fourth quarter of 1990. PSC has gone out for bid on the decontamination and dismantlement of FSV. This paper includes the defueling schedule, the independent spent fuel storage installation status, the probability of shipping fuel to DOE, the status of the preliminary decommissioning plan submittal, the issuance of a possession only license and what are the results of obtaining this license amendment, preliminary decommissioning activities allowed prior to the approval of a proposed decommissioning plan, the preparation of a proposed decommissioning plan and the status of our decision to proceed with SAFSTOR or DECON as identified in the NRC's final decommissioning rule

    Argonne National Laboratory has prepared a master environmental plan (MEP) for Fort Devens, Massachusetts, for the US Army Toxic and Hazardous Materials Agency. The MEP is an assessment based on environmental laws and regulations of both the federal government and the Commonwealth of Massachusetts. The MEP assess the physical and environmental status of 58 potential hazardous waste sites, including 54 study areas (SAs) that pose a potential for releasing contamination into the environment and 4 areas of concern (AOCs) that are known to have substantial contamination. For each SA or AOC, this MEP describes the known history and environment, identifies additional data needs, and proposes possible response actions. Most recommended response actions consist of environmental sampling and monitoring and other characterization studies. 74 refs., 63 figs., 50 tabs.

    Full Text Available Introduction. LeFort colpocleisis (LFC is a safe and effective obliterative surgical option for older women with advanced pelvic organ prolapse who no longer desire coital activity. A major disadvantage is the limited ability to evaluate for post-LFC gynecologic malignancies. Methods. We present the first case of endometrioid ovarian cancer diagnosed after LFC and review all reported gynecologic malignancies post-LFC in the English medical literature. Results. This is the second reported ovarian cancer post-LFC and the first of the endometrioid subtype. A total of nine other gynecologic malignancies post-LFC have been reported in the English medical literature. Conclusions. Gynecologic malignancies post-LFC are rare. We propose a simple 3-step strategy in evaluating post-LFC malignancies.

  5. Fort St. Vrain defueling ampersand decommissioning considerations

    International Nuclear Information System (INIS)

    Fort St. Vrain Nuclear Generating Station (FSV) is one of the first commercial reactors to be decommissioned under NRC's decommissioning rule. The defueling and decommissioning of this 330 MWe High Temperature Gas Cooled Reactor (HTGR) has involved many challenges for Public Service Company of Colorado (PSC) including defueling to an Independent Spent Fuel Storage Installation (ISFSI), establishing decommissioning funding, obtaining regulatory approvals, arranging for waste disposal, and managing a large fixed price decommissioning contract. In 1990, a team comprised of the Westinghouse Corporation and Morrison Knudsen Corporation, with the Scientific Ecology Group as a major subcontractor, was contracted by PSC to perform the decommissioning under a fixed price contract. Physical work activities began in August 1992. Currently, physical dismantlement activities are about 45% complete, the project is on schedule, and is within budget

  6. Decommissioning progress at Fort St Vrain

    International Nuclear Information System (INIS)

    The Fort St. Vrain Nuclear Generating Station in Colorado in the United States is well along in Decommissioning for release of the site from its Nuclear Regulatory Commission license. This decommissioning is being performed under a fixed price contract between the owner, Public Service Company of Colorado and a team of Westinghouse and Morrison-Knudsen. This paper will discuss the innovative decommissioning technique of filling the gas cooled reactor with water for shielding and contamination control and the other practical and readily available technologies used. This Decommissioning is demonstrating that a full size commercial nuclear reactor can be successfully decommissioned with a reasonable schedule, cost, and radiation dose to the work force. (Author)

  7. Operational experience at Fort St. Vrain

    International Nuclear Information System (INIS)

    The Fort St. Vrain (FSV) station, a 330-MW(e) single reheat steam cycle powered by a high-temperature gas-cooled reactor (HTGR), is the first HTGR to enter commercial operation. Designed and built by General Atomic Company (GA), the plant is owned and operated by Public Service Company of Colorado (PSC). Many unique design features have been incorporated into this reactor system, including high-pressure helium as the primary system coolant, a graphite-moderated prismatic block core design, fission-product-containing carbide coatings on both fissile and fertile fuel particles, steam-driven helium circulators turning on water bearings, and once-through steam generators. All of these systems are contained in a prestressed concrete reactor vessel (PCRV). Extensive testing has been conducted during the rise to power following first criticality early in 1974 to verify system design performance. During this period, the plant has operated at power levels up to 70% and produced over one billion kilowatt hours of electricity. In 1979, the first refueling was conducted in conjunction with an extensive in-core inspection, the addition of in-core instrumentation, and a planned removal of a circulator for inspection. Later in the year, a scheduled shutdown was undertaken for surveillance tests, insertion of core region constraint devices (RCDs), and other maintenance. Fort St. Vrain has encountered problems of the type that would be expected in a first-of-a-kind system. The plant is currently restricted to 70% of design power by the Nuclear Regulatory Commission (NRC) pending resolution of the core region gas outlet temperature fluctuation problem. Even so, the basic performance of the HTGR concept and all of the unique design features have been successfully demonstrated. The system has been characterized by low personnel radiation exposures, operational flexibility, and long time afforded for status evaluation and response. (author)

  8. Core temperature fluctuations and redistributions at Fort St. Vrain HTGR

    International Nuclear Information System (INIS)

    Fort St. Vrain high temperature gas-cooled reactor in the USA has exhibited two types of anomalous behavior called core temperature fluctuations and redistributions during the rise-to-power test program. These originally unexpected phenomena pose an important technical issue to the design, research and development works for JAERI experimental VHTR consisting of prismatic block type fuel elements similar to those of Fort St. Vrain. This report reviews the fluctuation/redistribution problem encountered in Fort St. Vrain along with its resolution. (author)

  15. SPace Radar Image of Fort Irwin, California

    Science.gov (United States)

    1994-01-01

    This image of Fort Irwin in California's Mojave Desert compares interferometric radar signatures topography -- data that were obtained by multiple imaging of the same region to produce three-dimensional elevation maps -- as it was obtained on October 7-8, 1994 by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar aboard the space shuttle Endeavour. Data were acquired using the L-band (24 centimeter wavelength) and C-band (6 centimeter wavelength). The image covers an area about 25 kilometers by 70 kilometers (15.5 miles by 43 miles). North is to the lower right of the image. The color contours shown are proportional to the topographic elevation. With a wavelength one-fourth that of the L-band, the results from the C-band cycle through the color contours four times faster for a given elevation change. Detailed comparisons of these multiple frequency data over different terrain types will provide insights in the future into wavelength-dependent effects of penetration and scattering on the topography measurement accuracy. Fort Irwin is an ideal site for such detailed digital elevation model comparisons because a number of high precision digital models of the area already exist from conventional measurements as well as from airborne interferometric SAR data. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human

    Kobayashi, Shinji; Fukawa, Toshihiko; Hirakawa, Takashi; Satake, Toshihiko; Maegawa, Jiro

    2016-02-01

    The Le Fort II osteotomy is a relatively rare operation. The posterior wall osteotomy of the maxillary sinus (MS) is often difficult for Le Fort III. We developed the transmaxillary sinus approach (TSA) for the Le Fort II osteotomy that cuts the posterior wall of the MS directly. This report illustrates this easy-to-use procedure for the Le Fort II osteotomy in syndromic craniosynostosis. This procedure was performed in an 18-year-old patient with Apert syndrome and a 15-year-old patient with Pfeiffer syndrome. The thin anterior walls of the MS were removed through an intraoral approach to look inside the MS. Then, the posterior walls were cut by chisel under direct vision using light. The other osteotomy was performed as usual. Distraction osteogenesis with internal and external devices was used in combination. The advantages of TSA are the direct posterior wall osteotomy of the MS with no down fracture and minimal invasiveness to the mucosa of the MS under direct vision. However, the disadvantage is that TSA becomes a blind procedure in a case with no MS or hypoplasia. We developed the TSA for the Le Fort II osteotomy, which could provide direct observation and perform the posterior wall osteotomy of the MS without down fracture. We believe that TSA is an effective surgical procedure for the Le Fort II osteotomy. PMID:27014548

  18. Fort St. Vrain hot functional test results

    International Nuclear Information System (INIS)

    A description is given of Fort St. Vrain hot functional tests performed to evaluate the initial nonnuclear performance of the primary coolant system and the associated effects on the various internal components of the reactor vessel and primary coolant system. The components included the twelve steam generator modules, the four helium circulators, the PCRV thermal barrier and liner coolant system, the helium purification system, and the primary and secondary closures at each of the PCRV penetrations. Additional objectives included analysis of the parallel operation of the four helium circulators and the performance of several circulator start/stop transients under various conditions of primary coolant temperature and pressure. Vibration and acoustical phenomena within the vessel were measured, recorded, and compared to theoretical analyses; a verification of reverse flow in the shutdown loop steam generator during one loop operation was performed; the PCRV was again observed for its structural response to internal pressure; and comparisons were made relative to data recorded during the initial pressure test completed in July 1971.

  19. Decommissioning progress at Fort St. Vrain

    International Nuclear Information System (INIS)

    Decommissioning of commercial nuclear power plants in the US has initiated with the current dismantling of the Fort St. Vrain Nuclear Generation Station in Colorado. Owned and operated by Public Service Company of Colorado (PSC), the unit was permanently shutdown in 1989. After a thorough evaluation by the utility of the DECON versus SAFSTOR options, the decision was made to proceed with decommissioning the power station for unrestricted release. In 1990 a team comprised of Westinghouse Electric Corporation and Morrison Knudsen Corporation was selected by PSC to perform the decommissioning on a fixed price, turnkey basis. The Westinghouse Team (WT) concept was based on an innovative approach for dismantling the Prestressed Concrete Reactor Vessel (PCRV) by flooding it and performing most operations using underwater tooling. This approach provided the maximum shielding and contamination control along with an optimum balance of schedule, cost and ALARA with minimum risks. An overview of the decommissioning progress to date plus overall perspectives of the factors facing utilities in this area will be reviewed

  20. HTGR startup experience at Fort St. Vrain

    International Nuclear Information System (INIS)

    Fort St. Vrain Unit 1, a 330-MW(e) HTGR being built by General Atomic for the Public Service Co. of Colorado, is located about 40 miles north of Denver. Construction began in 1968 and fuel was loaded under the first phase of the two-phase license in January 1974. The reactor has been critical a number of times to perform physics tests, but has been restrained until recently from producing any sensible heat by the restrictions of the second phase of the license. All prerequisites to the second and last phase of the license were satisfied on November 14 and the 40-year, full-power license went into effect. Since then, hot physics tests have been performed and feedwater has been introduced into the steam generators. All prerequisite testing is complete and feedwater chemistry is within specification for steam generator boilout. The plant is presently shut down and in a standby condition while the backup pelton wheels on the four primary helium circulators are being changed to an improved material. Upon completion of this change, now scheduled for the end of January, the rise-to-power program will begin.

  1. Littoral processes: US Coast Guard Station, Fort Point, San Francisco

    Energy Technology Data Exchange (ETDEWEB)

    Ecker, R.M.; Whelan, G.

    1983-10-01

    The US Coast Guard Station, Fort Point is located three-quarters of a nautical mile southeast of the Golden Gate Strait, the entrance to San Francisco Bay. The existing storm wave conditions at Fort Point Station pier make it extremely dangerous for the SAR crews to get on and off the Motor Life Boats at times requiring the vessels to be moored at the San Francisco Yacht Harbor about 1.5 miles east of the Fort Point Station. To mitigate these harsh working conditions the US Coast Guard is considering the feasibility of constructing suitable all-weather moorings for the three Motor Life Boats at the Fort Point Station to enable unimpeded SAR operations, to provide safe working conditions for Coast Guard small boat crews, and to improve small boat maintenance conditions at Fort Point Station. The purpose of this report is to identify, analyze and evaluate physical environmental factors that could affect all-weather moorings siting, configuration and entrance location, as well as potential post construction alterations to littoral conditions and processes. This report includes a description of the site, description of pertinent littoral processes, evaluation of how these processes could affect construction of all-weather moorings, and discussion of design considerations, as well as mitigation measures to minimize potential adverse effects to the physical environment. 19 references, 27 figures, 26 tables.

    The Le Fort I osteotomy is performed under general anaesthesia and specific haemodynamic conditions, i.e. hypotensive general anaesthesia. This study assessed the incidence of the trigeminocardiac reflex (TCR) during the different stages of the Le Fort I osteotomy. Forty-seven patients requiring a Le Fort I osteotomy were included. General anaesthesia was induced. In terms of haemodynamic changes, each patient's oxygen saturation (SpO2), mean arterial pressure (MAP), heart rate (HR), and electrocardiogram (ECG) were monitored by SADAAT Monitoring System and recorded during the different stages of osteotomy: before the induction of anaesthesia, before osteotomy cuts, after finishing the right pterygoid plate osteotomy, after finishing the left pterygoid plate osteotomy, and after performing down-fracture of the maxilla. No significant alteration in haemodynamic values was seen at the different stages of Le Fort I osteotomy. One patient showed arrhythmia with non-sinus junction rhythm after sinus bradycardia and two premature atrial contractions in the down-fracture stage, which led to the abrupt cessation of the procedure by the surgeon. This study showed no significant alterations in haemodynamic values during the different stages of Le Fort I osteotomy. Halting the procedure momentarily was sufficient to allow spontaneous normalization of the HR, blood pressure, and dysrhythmia. PMID:26794400

  3. Thunderstorm and Lightning Studies using the FORTE Optical Lightning System (FORTE/OLS)

    International Nuclear Information System (INIS)

    Preliminary observations of simultaneous RF and optical emissions from lightning as seen by the FORTE spacecraft are presented. RF/optical pairs of waveforms are routinely collected both as individual lightning events and as sequences of events associated with cloud-to-ground (CG) and intra-cloud (IC) flashes. CG pulses can be distinguished from IC pulses based on the properties of the RF and optical waveforms, but mostly based on the associated RF spectrograms. The RF spectrograms are very similar to previous ground-based VHF observations of lightning and show signatures associated with return strokes, stepped and dart leaders, and attachment processes,. RF emissions are observed to precede the arrival of optical emissions at the satellite by a mean value of 280 microseconds. The dual phenomenology nature of these observations are discussed in terms of their ability to contribute to a satellite-based lightning monitoring mission

    The Fort McMurray Historic Uranium Cleanup Project involved the removal of 42,000 m{sup 3} of soils contaminated with uranium ores and ore concentrates from various properties in the City of Fort McMurray, Alberta. These soils were placed into long-term management in a dedicated, locally developed and secure facility. The soil contamination addressed by the program was the result of incidental spillage and tracking of ores during the unloading of barges and the loading of rail cars as materials were transported via Fort McMurray from uranium mines in the Northwest Territories to a refinery in Port Hope, Ontario. The project was executed over a 10- year time period, involved the participation of the local community at critical junctures, and restored 28 ha of land to productive use. (author)

  8. Construction experience on PCRV liners at Fort St. Vrain

    International Nuclear Information System (INIS)

    The construction of the steel liners for the Fort St. Vrain prestressed concrete reactor vessel presented many unique problems for which techniques were developed to satisfy the rigid specification requirements. The PCRV cavity liner was fabricated from 1.9cm carbon steel plate. The liners were partially fabricated by Pittsburgh-Des Moines Steel Company at their Pittsburgh manufacturing facility. The liners were then shipped by rail to within approximately five miles of the jobsite and then trucked the remaining distance. The construction techniques, dimensional control, concrete support and testing utilized on the Fort St. Vrain project are presented in detail and demonstrate the flexibility of the PCRV for field construction.

  20. Fort Peck-Wolf Point transmission line project, Montana

    International Nuclear Information System (INIS)

    The primary objective of the project is to replace the existing 36-mile Fort Peck-Wolf Point transmission line which has reached the end of its useful service life. Presently, the overall condition of this existing section of the 47-year-old line is poor. Frequent repairs have been required because of the absence of overhead ground wires. The continued maintenance of the line will become more expensive and customer interruptions will persist because of the damage due to lightning. The expense of replacing shell rotted poles, and the concern for the safety of the maintenance personnel because of hazards caused by severe shell rot are also of primary importance. The operational and maintenance problems coupled with power system simulation studies, demonstrate the need for improvements to the Wolf Point area to serve area loads. Western's Wolf Point Substation is an important point of interconnection for the power output from the Fort Peck Dam to area loads as far away as Williston, North Dakota. The proposed transmission line replacement would assure that there will continue to be reliable transmission capacity available to serve area electrical loads, as well as provide a reliable second high-voltage transmission path from the Fort Peck generation to back-up a loss of the Fort Peck-Wolf Point 115-kV Line No. 1

  3. Measurements of transionospheric radio propagation parameters using the FORTE satellite

    International Nuclear Information System (INIS)

    We report initial measurements of ionospheric propagation parameters, particularly the total electron content (TEC), using the recently launched FORTE satellite. FORTE, which orbits the Earth at an altitude of 800 km and an inclination of 70 degree, contains a set of wideband radio receivers whose output is digitally recorded. A specialized triggering circuit identifies transient, broadband radio events, which include radiation from lightning, transionospheric pulse pairs, and man-made sources. Event data are transmitted to the ground station for analysis. In this paper we examine signals transmitted from an electromagnetic pulse generator operated at Los Alamos. The transmitter produces nearly impulsive signals in the VHF range. The received signal is dispersed by the ionosphere, and the received signal can be analyzed to deduce the total electron content along the path. By comparing the slant TEC thus measured with results from a ray-tracing code, we can deduce the vertical TEC to 800 km. Data from eight passes are presented. These types of data (in larger quantities) are of interest to operators of radar altimeters, who need data to corroborate their corrections for the ionospheric TEC. The combination of FORTE TEC data to 800 km and TEC measurements to 20,000 km (the Global Positioning System orbital altitude) can provide useful information for assessing the validity of models of plasmaspheric electron density. Initial estimates of the plasmaspheric density, on two daytime passes, are about 6 TECU. The signal received by FORTE, which is linearly polarized at the transmitter, is split into two magnetoionic modes by the ionosphere. The receiving antenna is also linearly polarized and therefore receives both modes. By measuring the beat frequency between the two modes, we can deduce the product of the geomagnetic field and the cosine of the angle between the field and the propagation vector. The possibility of using the measured slant TEC and the beat frequency to

  6. Decontamination and its role in the Fort St. Vrain decommissioning

    International Nuclear Information System (INIS)

    The full scale decommissioning of a reactor requires the use of a variety of decontamination processes, techniques and equipment. In August of 1992, the decommissioning of the Fort St. Vrain High Temperature Gas-Cooled Reactor (HTGR) was initiated by Public Service Company of Colorado. The Fort St. Vrain Decommissioning Project is being performed by a team comprised of Westinghouse Electric Corporation, Scientific Ecology Group, and MK Ferguson. This project is the largest decommissioning and early dismantlement of a commercially operated reactor in the United States to date. The scope of the project includes decontamination and dismantlement of the Prestressed Concrete Reactor Vessel (PCRV) and decontamination/removal of contaminated plant systems, site cleanup, and a comprehensive final radiation survey. This paper discusses the various types of decontamination equipment, survey instrumentation and techniques used during the Fort St. Vrain Decommissioning Project. Decontamination techniques range from simple methods such as soapy water, high pressure washing, scabbling, strippable paint; to more complicated methods such as remotely operated grit blast equipment used to decontaminate embedded pipe. The parameters necessary to evaluate the cost effectiveness of various decontamination techniques are discussed. Typically this includes consideration of the type and level of contamination, the substrate and surface to be decontaminated, the type and volume of waste generated from the decontamination process, whether the decon will be performed on site or off site, equipment and labor costs, project schedule impact, and the unconditional release criteria that must be achieved. These factors and costs are then compared to the costs associated with the removal, possible volume reduction and final disposal of a particular component or system. The successes and lessons learned during the Fort St. Vrain Decommissioning Project are presented

    Full Text Available Studies that measure the brand equity of destination brands by using the Customer-Based Brand Equity (CBBE model in a developing country context are scarce. The present study investigates the destination brand equity of the Lahore Fort by employing the CBBE model in a developing country context of Pakistan. Following the positivist tradition, we adopted a survey-based approach to collect data from 237 tourists visiting the Lahore Fort. Data were collected through a questionnaire developed to explain the relationship of brand awareness, brand image, brand association, and brand loyalty with Lahore Fort’s overall brand equity. We used various robust statistical techniques such as correlation, regression and confirmatory factor analysis (using PLS method to reach meaningful conclusions and found that brand image and brand associations positively contribute to brand loyalty. Furthermore, brand loyalty significantly contributes towards overall brand equity. Pragmatically, this study measures the customer based brand equity of the Lahore Fort, a destination brand. The results are useful as they suggest a few strategies that can help policy makers to enhance Lahore Fort’s brand performance.

  8. An aerial radiological survey of the Fort Calhoun Nuclear Power Plant and surrounding area, Fort Calhoun, Nebraska

    International Nuclear Information System (INIS)

    An aerial radiological survey was conducted over the Fort Calhoun Nuclear Power Plant in Fort Calhoun, Nebraska, during the period June 19 through June 28, 1993. The survey was conducted at an altitude of 150 feet (46 meters) over a 25-square-mile (65-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Fort Calhoun Nuclear Power Plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 12 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and potassium. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey was conducted on August 9 and 10, 1972, before the plant began operation. Exposure rates measured in both surveys were consistent with normal terrestrial background

  11. ALARA and decommissioning: The Fort St. Vrain experience

    International Nuclear Information System (INIS)

    The Fort St. Vrain Nuclear Generating Station, the first and only commercial High Temperature Gas Cooled Reactor to operate in the United States, completed initial fuel loading in late 1973 and initial startup in early 1974. Due to a series of non-nuclear technical problems, Fort St. Vrain never operated consistently, attaining a lifetime capacity factor of slightly less than 15%. In August of 1989, the decision was made to permanently shut down the plant due to control rod drive and steam generator ring header failures. Public Service Company of Colorado elected to proceed with early dismantlement (DECON) as opposed to SAFSTOR on the bases of perceived societal benefits, rad waste, and exposure considerations, regulatory uncertainties associated with SAFSTOR, and cost. The decommissioning of Fort St. Vrain began in August of 1992, and is scheduled to be completed in early 1996. Decommissioning is being conducted by a team consisting of Westinghouse, MK-Ferguson, and Scientific Ecology Group. Public Service Company of Colorado as the licensee provides contract management and oversight of contractor functions. An aggressive program to maintain project radiation exposures As Low As Reasonably Achievable (ALARA) has been established, with the following program elements: temporary and permanent shielding contamination control; mockup training; engineering controls; worker awareness; integrated work package reviews communication; special instrumentation; video camera usage; robotics application; and project committees. To date, worker exposures have been less than project estimates. from the start of the project through Februrary of 1994, total exposure has been 98.666 person-rem, compared to the project estimate of 433 person-rem and goal of 347 person-rem. The presentation will discuss the site characterization efforts, the radiological performance indicator program, and the final site release survey plans

  12. Operating experience with the Fort St. Vrain Nuclear Power Station

    International Nuclear Information System (INIS)

    Since entering into commercial operation in 1979, the 330 MW(e) Fort St. Vrain HTGR has performed increasingly well, and it is now demonstrating the real promise of this advanced reactor type. As of this writing, the plant has operated routinely at 70% power with 38% thermal efficiency, the highest nuclear plant efficiency in the United States of America, and has generated over 2,500,000 MW.h of electricity. Monthly availability factors have reached 99%. The plant has operated in a testing mode over 90% power and reached full power on 6 November 1981. Fuel performance has continued to exceed expectations and the second refuelling was carried out in 1981 (the first was in 1979). Radioactivity levels in the helium coolant and around the plant are very low. Personnel exposure during 1979-80, computed on a unit electricity generated basis, was a few per cent of the average exposure at LWR plants. This paper reviews the lessons learned during the startup and first five years of operation of Fort St. Vrain, including core behaviour, fuel handling, helium coolant cleanup, primary system and balance-of-plant component and systems operation, and plant operation and maintenance experience. In addition, the ways in which the new regulations resulting from the accident at Three Mile Island have been implemented in this HTGR plant are described. Public Service Co. of Colorado and General Atomic Co. have, through Fort St. Vrain, generated a large base of experience in HTGR technology that can be applied to future projects in the United States and elsewhere.

    As part of the Army Net-Zero Energy Installation program, the Fort Carson Army Base requested that NREL evaluate the feasibility of adding a biomass boiler to the district heating system served by Building 1860. We have also developed an Excel-spreadsheet-based decision support tool--specific to the historic loads served by Building 1860--with which users can perform what-if analysis on gas costs, biomass costs, and other parameters. For economic reasons, we do not recommend adding a biomass system at this time.

  14. Decommissioning of Fort St. Vrain nuclear generating station

    International Nuclear Information System (INIS)

    In the U.S.A., a licensee can propose decontaminating a nuclear power plant using any of three methods: DECON, SAFSTOR, or ENTOMB. For the Fort St. Vrain reactor, DECON was chosen. According to this option, portions of the facility, containing radioactive contaminants, are dismantled and removed, or else decontaminated, soon after the cessation of power. The work to be done is of three kinds: decontamination and dismantlement of the pre-stressed concrete reactor vessel; decontamination or dismantling of actually or potentially contaminated balance of plant; and site cleanup and final site radiation survey. Each of these elements of the work is discussed

  15. Dynamic computer simulation of the Fort St. Vrain steam turbines

    International Nuclear Information System (INIS)

    A computer simulation is described for the dynamic response of the Fort St. Vrain nuclear reactor regenerative intermediate- and low-pressure steam turbines. The fundamental computer-modeling assumptions for the turbines and feedwater heaters are developed. A turbine heat balance specifying steam and feedwater conditions at a given generator load and the volumes of the feedwater heaters are all that are necessary as descriptive input parameters. Actual plant data for a generator load reduction from 100 to 50% power (which occurred as part of a plant transient on November 9, 1981) are compared with computer-generated predictions, with reasonably good agreement

  16. A reactivity accidents simulation of the Fort Saint Vrain HTGR

    Most resource management decisions involve the integrated use of biological, sociological, and economic information. Combining this information provides a more comprehensive basis for making effective land management and conservation decisions. Toward this end, scientists in the Policy Analysis and Science Assistance Branch (PASA) of the Fort Collins Science Center (FORT) contribute expert knowledge for natural resources management by conducting biological, social, economic, and institutional analyses of conservation policies and management practices. PASAi??s mission is to integrate biological, social, and economic research so that resource managers can use the resulting information to make informed decisions and resolve resource management confl icts. PASA scientists pursue and conduct scientific analyses that help agencies and Native American tribes to (1) identify impending policy controversies and areas where social and natural science research is needed to address future policy questions; (2) develop methods and approaches to assist researchers in preparing scientific evidence; (3) assess habitat alteration in a manner consistent with policy needs; and (4) evaluate policy options. Branch scientists also evaluate policy options (e.g., effects of different land treatments, fish and wildlife management practices, or visitor/recreation management practices) in response to specifi c questions faced by policymakers and managers.

  18. Strategic Energy Management Plan For Fort Buchanan, Puerto Rico

    Energy Technology Data Exchange (ETDEWEB)

    Parker, Steven A.; Hunt, W. D.

    2001-10-31

    This document reports findings and recommendations as a result of a design assistance project with Fort Buchanan with the goals of developing a Strategic Energy Management Plan for the Site. A strategy has been developed with three major elements in mind: 1) development of a strong foundation from which to build, 2) understanding technologies that are available, and 3) exploring financing options to fund the implementation of improvements. The objective of this report is to outline a strategy that can be used by Fort Buchanan to further establish an effective energy management program. Once a strategy is accepted, the next step is to take action. Some of the strategies defined in this Plan may be implemented directly. Other strategies may require the development of a more sophisticated tactical, or operational, plan to detail a roadmap that will lead to successful realization of the goal. Similarly, some strategies are not single events. Rather, some strategies will require continuous efforts to maintain diligence or to change the culture of the Base occupants and their efforts to conserve energy resources.

  19. Fort Stewart integrated resource assessment. Volume 3: Resource assessment

    1993-10-01

    The US Army Forces Command (FORSCOM) has tasked the US Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory, to identify, evaluate, and assist in acquiring all cost-effective energy projects at Fort Stewart. This is part of a model program that PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the FORSCOM Fort Stewart facility located approximately 25 miles southwest of Savannah, Georgia. It is a companion report to Volume 1, Executive Summary, and Volume 2, Baseline Detail. The results of the analyses of EROs are presented in 11 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, along with a table detailing information on the installed cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. A description of the evaluation methodologies and technical and cost assumptions is also provided for each ERO. Summary tables present the cost-effectiveness of energy end-use equipment before and after the implementation of each ERO. The tables also present the results of the life-cycle cost (LCC) analysis indicating the net present value (NPV) and savings to investment ratio (SIR) of each ERO.

  20. Air Quality and Road Emission Results for Fort Stewart, Georgia

    Energy Technology Data Exchange (ETDEWEB)

    2004-02-02

    The Directorate of Public Works Environmental & Natural Resources Division (Fort Stewart /Hunter Army Airfield) contracted with the Pacific Northwest National Laboratory (PNNL) to monitor particulate matter (PM) concentrations on Fort Stewart, Georgia. The purpose of this investigation was to establish a PM sampling network using monitoring equipment typically used in U.S. Environmental Protection Agency (EPA) ''saturation sampling'', to determine air quality on the installation. In this initial study, the emphasis was on training-generated PM, not receptor PM loading. The majority of PM samples were 24-hr filter-based samples with sampling frequency ranging from every other day, to once every six days synchronized with the EPA 6th day national sampling schedule. Eight measurement sites were established and used to determine spatial variability in PM concentrations and evaluate whether fluctuations in PM appear to result from training activities and forest management practices on the installation. Data collected to date indicate the average installation PM2.5 concentration is lower than that of nearby urban Savannah, Georgia. At three sites near the installation perimeter, analyses to segregate PM concentrations by direction of air flow across the installation boundary indicate that air (below 80 ft) leaving the installation contains less PM2.5 than that entering the installation. This is reinforced by the observation that air near the ground is cleaner on average than the air at the top of the canopy.

  1. Solar Energy Development Assistance for Fort Hunter Liggett

    Energy Technology Data Exchange (ETDEWEB)

    Russo, Bryan J.; Hoffman, Michael G.; Chvala, William D.

    2011-03-30

    Pacific Northwest National Laboratory provided assistance to Fort Hunter Liggett to determine the opportunities for solar energy development on the site. Increasing use of renewable energy is mandated by several executive orders and legislation. Fort Hunter Liggett has many attributes that enhance its suitability for renewable energy development. First, the site is located south of San Francisco in a remote portion of the costal foothills. Brush and forest fires are frequent and often result in power outages, which subsequently impacts the site’s training mission. In addition, the site’s blended electric rate during fiscal year (FY) 2010 was high at 12 ¢/kWh. Lastly, the solar resource is moderately high; the site receives nearly 5.7 kWh/m2/day on a south facing, latitude-tilted surface. In light of these factors, the site is a clear candidate for a solar photovoltaic array. Prior to Pacific Northwest National Laboratory’s (PNNL) involvement, the site secured funding for a 1 megawatt (MW) photovoltaic (PV) array that will also provide shading for site vehicles. To best implement this project, PNNL conducted a site visit and was tasked with providing the site technical guidance and support regarding module selection, array siting, and other ancillary issues.

    CHEN We-jian; YANG Yun-jun; FANG Yi-ming; XU Fang-hong; ZHANG Lin; CAO Guo-quan

    2006-01-01

    Objective:To evaluate the usefulness of twodimensional (2D) and three-dimensional (3D) computed tomography (CT) in the identification and classification of Le Fort type fractures.Methods: Sixty-two patients with different types of Le Fort fractures underwent CT scanning and 3D-CT reconstruction. The data were analyzed by multiplanar reconstruction (MPR), surface shaded display (SSD) and volume rendering (VR) respectively.Results: The patients with Le Fort Ⅰ , Le Fort Ⅱfracture and Le Fort Ⅲ fracture accounted for 16.1%,14.5 % and 12.9 % respectively. The compound fractures were the most common type and accounted for 56.5 % ( n =35, 18 cases with Le Fort Ⅰ + Ⅱ fracture, 10 cases with Le Fort Ⅱ + Ⅲ fracture and 7 cases with Le Fort Ⅰ + Ⅱ + Ⅲfracture). Fifty-five cases coexisted with other fractures in maxillofacial region. 2D-CT could be used to define the tiny fractures and the deep-structure fractures more accurately compared with 3D-CT, but the real impression of Le Fort type fractures could not be correctly evaluated on 2D-CT.3D-CT could clearly demonstrate the whole shape of Le Fort type fractures and identify the classification of Le Fort fractures.Conclusions: 3D-CT is the best imaging method for the diagnosis of Le Fort type fractures and can provide valuable information of space relationship, especially for the design of treatment plan before operation.

  10. Revisiting "Narrow Bipolar Event" intracloud lightning using the FORTE satellite

    Directory of Open Access Journals (Sweden)

    A. R. Jacobson

    2012-02-01

    Full Text Available The lightning stroke called a "Narrow Bipolar Event", or NBE, is an intracloud discharge responsible for significant charge redistribution. The NBE occurs within 10–20 μs, and some associated process emits irregular bursts of intense radio noise, fading at shorter timescales, sporadically during the charge transfer. In previous reports, the NBE has been inferred to be quite different from other forms of lightning strokes, in two ways: First, the NBE has been inferred to be relatively dark (non-luminous compared to other lightning strokes. Second, the NBE has been inferred to be isolated within the storm, usually not participating in flashes, but when it is in a flash, the NBE has been inferred to be the flash initiator. These two inferences have sufficiently stark implications for NBE physics that they should be subjected to further independent test, with improved statistics. We attempt such a test with both optical and radio data from the FORTE satellite, and with lightning-stroke data from the Los Alamos Sferic Array.

    We show rigorously that by the metric of triggering the PDD optical photometer aboard the FORTE satellite, NBE discharges are indeed less luminous than ordinary lightning. Referred to an effective isotropic emitter at the cloud top, NBE light output is inferred to be less than ~3 × 108 W.

    To address isolation of NBEs, we first expand the pool of geolocated intracloud radio recordings, by borrowing geolocations from either the same flash's or the same storm's other recordings. In this manner we generate a pool of ~2 × 105 unique and independent FORTE intracloud radio recordings, whose slant range from the satellite can be inferred. We then use this slant range to calculate the Effective Radiated Power (ERP at the radio source, in the passband 26–49 MHz. Stratifying the radio recordings by ERP into eight bins, from a lowest bin (<5 kW to a highest bin (>140 kW, we document a

  11. Sensitivity comparative study in Philips Forte Gamma Camera

    International Nuclear Information System (INIS)

    Monte Carlo modeling is widely used in the development nuclear medical imaging systems, particularly in the adjustment of its main characteristics and parameters. It is essential to evaluate the behavior of the system sensitivity in real measurement conditions for specific patient. Planar studies of thyroid phantom were conducted in a Philips Forte Gamma Camera of the 'Hermanos Ameijeiras' Hospital. Experimental set up was totally reproduced in the simulation environment. A comparative study between the experimental and theoretical, obtained by Monte Carlo mathematical modeling, sensitivity values have been done. For simulation GAMOS (Geant4-Architecture for medicine Oriented Simulation) framework was used. The results obtained from both methods have shown an acceptable coincidence (less than 2%) of sensitivity. Therefore this paper aims to validate sensitivity studies carried out via Monte Carlo mathematical modeling and irs acceptable equivalence with experimental measurements in authentic medical circumstances.

  12. Fort St. Vrain independent spent fuel storage installation

    International Nuclear Information System (INIS)

    The Independent Spent Fuel Storage Installation (ISFSI) at Fort St. Vrain was conceived initially as a contingency plan for one segment of high temperature gas cooled reactor (HTGR) fuel. As the project evolved, the ISFSI was eventually designed and constructed for six segments of HTGR fuel. The approximately two year schedule for design, licensing, and construction of the ISFSI was completed on schedule and at the anticipated cost of $25 million. Loading fuel from the reactor to the ISFSI was completed two months ahead of schedule at a cost savings of $1,500,000. Actual occupational exposure was less than 7% of projected exposure. This paper attempts to inform the reader about technical aspects of the Public Service Company of Colorado ISFSI and how design, licensing, construction, and loading of the ISFSI was completed ahead of schedule and under cost

  13. Preplaced aggregate concrete application on Fort St. Vrain PCRV construction

    International Nuclear Information System (INIS)

    Two distinct concreting methods were employed in the construction of the prestressed concrete reactor vessel (PCRV) of the Fort St. Vrain (FSV) Nuclear Generating Station, a 330 MW(e) High Temperature Gas-Cooled Reactor installation near Denver, Colorado. Preplaced aggregate concrete (PAC) techniques were employed in the PCRV bottom head and the core support floor; conventional job-mixed concrete was used in the PCRV sidewall and top head regions. This paper describes the successful application of PAC techniques utilized primarily in solving construction difficulties associated with confined and heavily congested regions of the PCRV. The PAC technique consists of placing coarse aggregate inside the forms, followed by injection of grout under pressure through embedded pipes to fill the interstices in the aggregate mass. Details of the PAC construction method including grout mix development, grouting equipment, grout pipe layout, grouting sequence, grout level monitoring, concrete temperature control, and pre-construction mockups are described.

  14. The HTGR experience base at Fort St. Vrain

    International Nuclear Information System (INIS)

    GA Technologies Inc. is designing large hightemperature gas-cooled reactors (LHTGR's) for central station power and cogeneration applications. The 330-MW(e) Fort St. Vrain (FSV) plant operated by Public Service Company of Colorado provides the principal technical base for designing LHTGR's. It has demonstrated the prestressed concrete reactor vessel, once-through steam generators, and hexagonal block fuel elements. To gain the maximum advantage from FSV, a systematic, formal Experience Carryover Program (ECP) is examining FSV experience from research and development through construction, operation, and maintenance. Design features resulting from the ECP, in conjunction with other programs, including extensive foreign experience, should result in high LHTGR reliability and operability. This paper explains the major design differences between FSV and the LHTGR

  15. Fort St. Vrain high temperature gas-cooled reactor

    International Nuclear Information System (INIS)

    The construction, testing, and preliminary operating experience of the Fort St. Vrain Nuclear Generating Station are described. This station utilizes the advanced high-temperature gas-cooled reactor (HTGR) concept and is the first nuclear reactor system in the United States to use a prestressed concrete reactor vessel (PCRV). Helium is used as the primary coolant, and a nitrogen system provides refrigeration for the low temperature equipment of the helium purification system and for the moisture monitors in the primary coolant system. Design, construction and testing to date at this station have made a significant contribution to the HTGR concept for central station electric generating plants to supply the increasing demands for electrical energy.

  18. Fort St. Vrain graphite site mechanical separation concept selection

    International Nuclear Information System (INIS)

    One of the alternatives to the disposal of the Fort St. Vrain (FSV) reactor spent nuclear fuel involves the separation of the fuel rods composed of compacts from the graphite fuel block assembly. After the separation of these two components, the empty graphite fuel blocks would be disposed of as a low level waste (provided the appropriate requirements are met) and the fuel compacts would be treated as high level waste material. This report deals with the mechanical separation aspects concerning physical disassembly of the FSV graphite fuel element into the empty graphite fuel blocks and fuel compacts. This report recommends that a drilling technique is the preferred choice for accessing the, fuel channel holes and that each hole is drilled separately. This report does not cover any techniques or methods to separate the triso fuel particles from the graphite matrix of the fuel compacts

    The Tularosa-Hueco basin in south-central New Mexico has long been known as an extensional area of high heat flow. Much of the basin is within the Fort Bliss military reservation, which is an exceptionally high value customer for power independent of the regional electric grid and for direct use energy in building climate control. A series of slim holes drilled in the 1990s established the existence of a thermal anomaly but not its practical value. This study began in 2009 with a demonstration of new exploration drilling technology. The subsequent phases reported here delivered a useful well, comparative exploration data sets and encouragement for further development. A production-size well, RMI56-5, was sited after extensive study of archival and newly collected data in 2010-2011. Most of 2012 was taken up with getting state and Federal authorities to agree on a lead agency for permitting purposes, getting a drilling permit and redesigning the drilling program to suit available equipment. In 2013 we drilled, logged and tested a 924 m well on the McGregor Range at Fort Bliss using a reverse circulation rig. Rig tests demonstrated commercial permeability and the well has a 7-inch slotted liner for use either in production or injection. An August 2013 survey of the completed well showed a temperature of 90 C with no reversal, the highest such temperature in the vicinity. The well’s proximity to demand suggests a potentially valuable resource for direct use heat and emergency power generation. The drilling produced cuttings of excellent size and quality. These were subjected to traditional analyses (thin sections, XRD) and to the QEMScan™ for comparison. QEMScan™ technology includes algorithms for determining such properties of rocks as density, mineralogy, heavy/light atoms, and porosity to be compared with direct measurements of the cuttings. In addition to a complete cuttings set, conventional and resistivity image logs were obtained in the open hole before

    The potential for air quality impacts from heavy mechanized vehicles operating in the training ranges and on the unpaved main supply routes at Fort Bliss is being investigated. The investigation uses the atmospheric modeling system DUSTRAN to simulate fugitive dust emission and dispersion from typical activities occurring on the installation. This report conveys the results of DUSTRAN simulations conducted using a “Full Training” scenario developed by Fort Bliss personnel. he Full Training scenario includes simultaneous off-road activities of two full Heavy Brigade Combat Teams (HCBTs) and one HCBT battalion on three training ranges. Simulations were conducted for the six-day period, April 25-30, 2005, using previously archived meteorological records. Simulation results are presented in the form of 24-hour average PM10 plots and peak 1-hour PM10 concentration plots, where the concentrations represent contributions resulting from the specified military vehicular activities, not total ambient PM10 concentrations. Results indicate that the highest PM10 contribution concentrations occurred on April 30 when winds were light and variable. Under such conditions, lofted particulates generated by vehicular movement stay in the area of generation and are not readily dispersed. The effect of training duration was investigated by comparing simulations with vehicular activity extending over a ten hour period (0700 to 1700 MST) with simulations where vehicular activity was compressed into a one hour period (0700 to 0800 MST). Compressing all vehicular activity into one hour led to higher peak one-hour and 24-hour average concentration contributions, often substantially higher.

    2015-02-01

    This paper is composed of three elements: 3D modeling, web design, and heritage visualization. The aim is to use computer graphics design to inform and create an interest in historical visualization by rebuilding Fort Frontenac using 3D modeling and interactive design. The final model will be integr ated into an interactive website to learn more about the fort's historic imp ortance. It is apparent that using computer graphics can save time and money when it comes to historical visualization. Visitors do not have to travel to the actual archaeological buildings. They can simply use the Web in their own home to learn about this information virtually. Meticulously following historical records to create a sophisticated restoration of archaeological buildings will draw viewers into visualizations, such as the historical world of Fort Frontenac. As a result, it allows the viewers to effectively understand the fort's social sy stem, habits, and historical events.

    2010-04-01

    The Robotics Rodeo held from 31 August to 3 September 2009 at Fort Hood, Texas, had three stated goals: educate key decision makers and align the robotics industry; educate Soldiers and developers; and perform a live market survey of the current state of technologies to encourage the development of robotic systems to support operational needs. Both events that comprised the Robotics Rodeo, the Extravaganza and the robotic technology observation, demonstration and discussion (RTOD2) addressed these stated goals. The Extravaganza was designed to foster interaction between the vendors and the visitors who included the media, Soldiers, others in the robotics industry and key decision makers. The RTOD2 allowed the vendors a more private and focused interaction with the subject matter experts teams, this was the forum for the vendors to demonstrate their robotic systems that supported the III Corps operational needs statements that are focused on route clearance, convoy operations, persistent stare, and robotic wingman. While the goals of the Rodeo were achieved, the underlying success from the event is the development of a new business model that is focused on collapsing the current model to get technologies into the hands of our warfighters quicker. This new model takes the real time data collection from the Rodeo, the Warfighter Needs from TRADOC, the emerging requirements from our current engagements, and assistance from industry partners to develop a future Army strategy for the rapid fielding of unmanned systems technologies.

  20. Fort Stewart integrated resource assessment. Volume 1, Executive summary

    Energy Technology Data Exchange (ETDEWEB)

    Larson, L.L.; Keller, J.M.

    1993-10-01

    The US Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory (PNL), has developed a model program that provides a systematic approach to evaluating energy opportunities that (1) identifies the building groups and end uses that use the most energy (not just have the greatest energy-use intensity), and (2) evaluates the numerous options for retrofit or installation of new technology that will result in the selection of the most cost-effective technologies. In essence, this model program provides the federal energy manager with a roadmap to significantly reduce energy use in a planned, rational, cost-effective fashion that is not biased by the constraints of the typical funding sources available to federal sites. The results from this assessment process can easily be turned into a five- to ten-year energy management plan that identifies where to start and how to proceed in order to reach the mandated energy consumption targets. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the US Army US Forces Command (FORSCOM) Fort Stewart facility located approximately 25 miles southwest of Savannah, Georgia. It is a companion report to Volume 2, Baseline Detail, and Volume 3, Resource Assessment.

  1. Fort St. Vrain-A DOE Success Story.

    Science.gov (United States)

    Borst, Ted

    2003-02-01

    ABSTRACT The Fort St. Vrain Nuclear Generating Station was a one-of-its-kind High Temperature Gas Cooled Reactor located near Denver, CO. Due to operational difficulties, the reactor was permanently shut down in August 1989. Plans to ship the spent reactor fuel to Idaho were thwarted by the Governor of Idaho. The inability to ship the spent reactor fuel offsite necessitated the construction of an Independent Spent Fuel Storage Installation (ISFSI) in order to proceed with the decommissioning of the reactor. After loading the ISFSI, decommissioning of the reactor was initiated and successfully completed. At the same time, the site was repowered using natural gas. As part of a settlement with the owner of the reactor, the U.S. Department of Energy agreed to take title to the spent fuel in the ISFSI and obtain an NRC license for the facility. The license for the ISFSI was transferred to the DOE in June 1999. Day-to-day operations of the ISFSI are accomplished by the DOE's Maintenance and Operations contractor, Bechtel Babcock Wilcox Idaho (BBWI). BBWI also operates the Three Mile Island Unit 2 ISFSI in Idaho for the DOE. This paradigm for ISFSI operations has been highly successful and is expandable to additional ISFSIs that may come under the jurisdiction of the DOE. PMID:12555031

  2. Fort St. Vrain initial fuel loading and physics tests

    International Nuclear Information System (INIS)

    The full-power operating license for the Fort St. Vrain Nuclear Generation Station was issued by the AEC on December 21, 1973. Core loading was started on December 27, 1973, and the loading of the 2274 fuel and reflector elements was completed in 20 days. Initial criticality was achieved on January 31, 1974. The critical control rod position indicated an 0.003 Δk difference between the predicted and actual critical core configuration. Pulsed-neutron measurements were performed to obtain the shutdown margin with all control rods inserted, the shutdown margin with the highest worth control rod pairs removed, and the reactivity worth of the control rod groups removed in the normal sequence in the approach to critical. Following the initial criticality, measurements of the axial flux distribution were performed in several regions of the core. The cold zero power measurements were performed with air in the core so that personnel access to the core cavity was possible to permit placement of in-core instrumentation. After completion of the cold physics measurements, the special in-core instrumentation was removed and the primary system was sealed and filled with helium. Measurements of reactivity coefficients are scheduled to be performed as part of the hot physics testing. Additional physics tests are scheduled for the rise-to-power test program and include measurements of control rod worth, temperature coefficient, xenon reactivity, and xenon stability

  3. Fort St. Vrain fuel-handling system RAM analysis

    International Nuclear Information System (INIS)

    Public Service of Company of Colorado (PSC) is planning to decommission its Fort St. Vrain plant in 1990. This requires removal of 1,500 separate assemblies from the core. With the low historical availability of the fuel-handling system (FHS), defueling time was estimated at 36 months. With plant expenses of approximately $1.6 million per month during defueling, this would mean a schedule cost of $58 million. With their contractor, Rockwell International, PSC embarked on a reliability, availability, and maintainability (RAM) analysis to reduce projected defueling time. Key elements included (a) estimating availability of the FHS using a limited historical record, (b) assessing the defueling critical path, and (c) proposing and evaluating design/operational improvements. The most cost-effective improvements are being implemented and are expected to provide a reduction of >18 months in schedule and a net savings of $20 to 25 million. The paper describes the FHS design and operation, major problems associated with fuel-handling operations, and results and recommendations

  5. Habitat Restoration/Enhancement Fort Hall Reservation : 2008 Annual Report.

    Energy Technology Data Exchange (ETDEWEB)

    Osborne, Hunter [Shoshone Bannock Tribes

    2009-07-23

    Habitat enhancement, protection and monitoring were the focus of the Resident Fisheries Program during 2008. Enhancement and protection included sloping, fencing and planting wetlands plugs at sites on Spring Creek (Head-waters). Many previously constructed instream structures (rock barbs and wing dams) were repaired throughout the Fort Hall Indian Reservation (Reservation). Physical sampling during 2008 included sediment and depth measurements (SADMS) in Spring Creek at the Car Removal site. SADMS, used to track changes in channel morphology and specifically track movements of silt through Bottoms stream systems were completed for 5 strata on Spring Creek. Water temperature and chemistry were monitored monthly on Spring Creek, Clear Creek, Diggie Creek, and Portneuf (Jimmy Drinks) and Blackfoot rivers. Fish population densities and biomass were sampled in five reservation streams which included nine sites. Sampling protocols were identical to methods used in past years. Numbers of fish in Spring Creek series remained relatively low, however, there was an increase of biomass overall since 1993. Salmonid fry densities were monitored near Broncho Bridge and were similar to 2006, and 2007, however, as in years past, high densities of macrophytes make it very difficult to see fry in addition to lack of field technicians. Mean catch rate by anglers on Bottoms streams stayed the same as 2007 at 1.5/hr. Numbers of fish larger than 18-inches caught by anglers increased from 2007 at .20 to .26/hr.

  6. Fort Hall Reservation Stream Enhancement : 1999 Annual Report.

    1999-10-01

    Habitat enhancement and protection were the main focus of the Resident Fish Program during 1999. Biotic sampling included a genetic survey of salmonids on the Fort Hall Reservation. In addition, density and biomass of fish in select Bottoms streams was monitored. Enhancement and protection included anchoring 1,327 m of evergreen tree revetments and erecting three kilometers of enclosure fence. Physical sampling during 1999 included sediment and depth surveys and chemical measurements. Baseline SADM's, used to track changes in channel morphology and specifically track movements of silt through the system were completed for eight strata in Big Jimmy Creek. Numbers of fish in Clear creek were much lower than previous years. In addition, numbers of fry counted at Broncho Bridge were significantly lower than previous years. Future monitoring will determine whether low numbers are cyclic and related to weak year classes or low numbers are the result of anthropogenic influences. Permit fishing seasons continued to provide a source of income for the Tribes and an opportunity for non-tribal members to fish Bottoms streams. Mean catch rate by anglers on Bottoms streams increased from that of previous years to 1.02 fish per hour.

  7. Scottish vitrified forts: background and potential for TL dating

    International Nuclear Information System (INIS)

    Scottish vitrified forts have been the subject of considerable interest since their discovery in the late 18th century. This presentation deals with the nature of these sites, their archaeological, historical and technical backgrounds, the existing chronological evidence from 14C dates and the potential for thermoluminescence dating revealed by a short feasibility study. The dosimetric properties of a range of sites are evaluated in some detail using a combination of X-ray fluorescence analysis, neutron activation analysis, high resolution gamma ray spectrometry and on site NaI spectroscopy. Favourable conditions are encountered in many cases particularly for samples extracted from infinite gamma matrices using a diamond coring technique. The TL properties of quartz inclusions from such samples are discussed. In addition to examples showing conventional behaviour, some samples have exhibited severe supralinearity coupled to sensitisation which presents obstacles to dating. Tests for such 'malign' behaviour are proposed which will add to the reliability of TL dates from this type of sample. (author)

  8. DSM/Federal energy efficiency partnership program at Fort Lewis, Washington

    International Nuclear Information System (INIS)

    The Energy Systems Modernization Office (ESMO) at Pacific Northwest Laboratory (PNL) is developing and applying the Federal Energy Decision Screening (FEDS) system for federal installations in cooperation with the servicing utility(s). The process involves five parts: assess installation-wide, fuel-blind energy-efficiency resource, identify the most life-cycle cost-effective technologies, work with the servicing utility to develop a program to implement energy conservation projects and technologies, evaluate rates and rate structures, and contribute to the design and implementation of an energy savings verification procedure to evaluate the impact of installed technologies. Fort Lewis, a large military installation in Tacoma, Washington, was identified as a site for a pilot program. Fort Lewis has an annual electric load of about 195,000 megawatt-hours (MWh)(-40 MW). An energy conservation supply curve was developed showing the amount of electric energy savings that can be achieved at different prices for energy saved. From these data, a proposal was prepared for acquiring approximately 43,000 kilowatt-hours (kWh) (-4 MW) of annual cost-effective electric energy savings, which TPU presented to Bonneville. This proposal identified investment requirements at the Fort and the likely energy and dollar savings. Approximately $10 million of investment in electrical energy efficient end-use technology was estimated to be cost-effective at Fort Lewis under this arrangement. In the agreement with Fort Lewis, TPU will finance 100% of this investment and will procure the energy services contractor who will conduct the detailed audits and install the technologies. The Fort will repay TAU 15% of the total installed cost of the technology over the time period of the installation of the technologies. The result is that Fort Lewis will see a reduction in its electric bill of approximately $500,000/year, depending on the final program design

  9. Habitat restoration/enhancement Fort Hall Reservation : 2001 annual report

    International Nuclear Information System (INIS)

    Habitat enhancement, protection and monitoring were the focus of the Resident Fisheries Program during 2001. Enhancement and protection included sloping, fencing and planting willows at sites on Diggie Creek, Clear Creek and Spring Creek. In addition, many previously constructed instream structures (rock barbs and wing dams) were repaired throughout the Fort Hall Indian Reservation (Reservation). In 2001, exclosure fences were erected on Diggie Creek (250 m barbed wire; (70 m jack), Wood Creek (500 m jack), Clear Creek (20 m jack), Ross Fork Creek (200 m jack), West Fork Creek (200 m jack)) and the Portneuf River (1 km barbed wire; 100 m jack). Jack and rail exclosure fences that had deteriorated over the past ten years were repaired at numerous areas throughout the Reservation. Physical sampling during 2001 included sediment and depth surveys (SADMS) in Big Jimmy Creek and Diggie Creek. SADMS, used to track changes in channel morphology and specifically track movements of silt through Bottoms stream systems were completed for eight and nine strata in the Big Jimmy and Diggie Creek, respectively. Baseline SADM data was collected in Diggie Creek to monitor the effects of bank sloping and revegetation on channel morphology and sediment levels through time. Water temperature was monitored (hourly) in Spring Creek, Clear Creek, Ross Fork Creek and Big Jimmy Creek. Biotic sampling included invertebrate sampling in the 200 and 300 series of Clear Creek. Fish population densities and biomass were sampled in Clear Creek 200 and 300 series. Sampling protocols were identical to methods used in past years. Numbers of fish in Clear Creek 300 series remained similar to 2000 while numbers of fish in Clear Creek 200 series dropped to near pre project levels. Salmonid fry densities were monitored near Broncho Bridge and were significantly higher than 2000. A mark-recapture study was initiated in spring 2001 to estimate numbers of spawning adults using the Head End of Spring Creek

    Hanselman, W.; Jennings, E.

    1982-09-01

    The City of Fort Wayne conducted a feasibility assessment of the potential for a district heating and cooling system to service the southern end of the CBD. A complete inventory of potential heat sources (principally industrial) was made, as well as an inventory of concentrated areas of demand for heat. Fort Wayne conditionally determined that it lacked a truly viable source of thermal energy. There were marginal sources including one refinery but the quality of the heat was low. Trash-fired heat was examined but a good, reliable, and sufficiently large source was not identified.

  14. Delayed progressive haematoma after Le Fort I osteotomy: A possible severe complication in orthognatic surgery

    Directory of Open Access Journals (Sweden)

    Dario Bertossi

    2012-01-01

    Full Text Available Although the Le Fort I osteotomy is a safe surgical technique, many complications have been reported. We present a case of an extended cervico-facial haematoma due to delayed bleeding from the terminal branches of the maxillary artery after orthognatic surgery. A 23-year-old man was referred to our observation for the surgical correction of a class III asymmetric malocclusion. The patient underwent a Le Fort I osteotomy, with impaction of the maxilla, associated with an Epker mandibular bilateral sagittal split osteotomy, with maxillary advancement and rigid internal fixation of the mandible with four miniplates and another four for the upper maxilla as well. The first post-surgery day, the patient developed a gradual dispnea together with neck swelling. By second postoperative day, the patient′s general condition improved with a progressive normalization of laboratory tests values. The Computerised Axial Tomography (CAT scan confirmed a decrease in the parapharyngeal thickening. Total recovery was achieved within two months, the final clinical check showed a healthy appearance with good occlusion. An increased knowledge of the basic biology of the Le Fort I osteotomy, the development of instruments specially designed for the Le Fort I procedure and the use of hypotensive anaesthesia could reduce the morbidity and duration of this procedure.

  17. Pictorial account and landscape evolution of the crevasses near Fort St. Philip, Louisiana

    Science.gov (United States)

    Suir, Glenn M.; Jones, William R.; Garber, Adrienne L.; Barras, John A.

    2014-01-01

    Quantifying the effects of active natural and constructed crevasses is critical to the planning and success of future ecosystem restoration activities. This document provides a historical overview of landscape changes within the vicinity of the natural crevasses near Fort St. Philip, Louisiana. A significant event influencing landscape change within the Fort St. Philip study area was the breaching of the eastern levee of the Mississippi River. Initially, the river water that was diverted through these crevasse channels physically removed significant marsh areas within the study area. These initial direct impacts were succeeded by several decades of larger regional loss patterns driven by subsidence and other episodic events (e.g, hurricanes and floods), and recent localized land gains. These increases in land area are potentially the long-term results of the Fort St. Philip crevasses, and the short-term impacts of delta management activities. However, for the majority of the 1956-2008 period of analysis, the crevassing of the eastern bank of the Mississippi River levee was a loss accelerant in the Fort St. Philip area.

  20. Third party testing : new pilot facility for mining processes opens in Fort McKay

    International Nuclear Information System (INIS)

    Fort McKay lies 65 kilometres north of Fort McMurray, Alberta and is the centre of operational oilsands mining activity. As such, it was chosen for a pilot testing facility created by the Geneva-based SGS Group. The reputable facility provides an opportunity for mining producers to advance their processes, including environmental performance, by allowing them to test different processes on their own oilsands. The Northern Lights partnership, led by Synenco Energy, was the first client at the facility. Due to outsourcing, clients are not obligated to make substantial capital investment into in-house research. The Northern Lights partnership will be using the facility to test extraction processes on bitumen from its leases. Although the Fort McKay facility is SGS's first venture into the oilsands industry, it operates in more than 140 companies globally, including the mineral industry, and specializes in inspection, verification, testing and certification. SGS took the experience from its minerals extraction business to identify what could be done to help the oilsands industry by using best practices developed from global operations. The facility lies on the Fort McKay industrial park owned by the Fort McKay First Nation. An existing testing facility called McMurray Resources Research and Testing was expanded by the SGS Group to include environmental analysis capabilities. The modular units that lie on 6 acres include refrigerated ore storage to maintain ore integrity; modular ore and materials handling systems; extraction equipment; and, zero discharge process water and waste disposal systems. Froth treatment will be added in the near future to cover the entire upstream side of the mining processing business. A micro-upgrader might be added in the future to manufacture synthetic crude. 3 figs

    2014-01-01

    Aeromagnetic data help provide the underpinnings of a hydrogeologic framework for Fort Irwin by locating inferred structural features or grain that influence groundwater flow. Magnetization boundaries defined by horizontal-gradient analyses coincide locally with Cenozoic faults and can be used to extend these faults beneath cover. These boundaries also highlight the structural grain within the crystalline rocks and may serve as a proxy for fracturing, an important source of permeability within the generally impermeable basement rocks, thus mapping potential groundwater pathways through and along the mountain ranges in the study area.

    Historically, the Fort Worth CHD has striven to provide the highest level of service toward the assurance of consumer safety. The burgeoning growth of the city, however, combined with limited resources, has challenged this capability. The response by CHD was to develop a long-term, orchestrated plan to not only maintain but also improve performance. To succeed, a multiyear, integrated plan to develop programming, personnel management, and budgeting was adopted. In accordance with this plan, the past five years have witnessed the cultivation and integration of strategic initiatives into a comprehensive and effective consumer safety program. The program has succeeded in improving inspections, lowering violation recidivism, maintaining compliance, and orchestrating activities to sustain improvements well into the future. CHD is proud of these accomplishments and of its service to the citizens of Fort Worth. In this spirit, CHD is happy to accept the 2004 Crumbine Award, which recognizes the dedication to consumer safety underlying this program. PMID:15628194

    Beginning June 14, the familiar bugle calls at Fort Detrick will be joined by a special percussion instrument: a cannon. A single cannon shot will be fired on the first note of “Reveille,” which signals the start of each day and is accompanied by the raising of the American flag. “Reveille” sounds at 6:30 a.m. At 5 p.m., Fort Detrick plays “Retreat,” which alerts the post that the flag is about to be lowered. The cannon will fire on the last note of “Retreat.” After a five-second pause, “To the Color” plays as the flag is lowered.

  6. A non-conventional procedure for the 3D modeling of WWI forts

    Science.gov (United States)

    Nocerino, E.; Fiorillo, F.; Minto, S.; Menna, F.; Remondino, F.

    2014-06-01

    2014 is the hundredth anniversary of the outbreak of the First World War (WWI) - or Great War - in Europe and a number of initiatives have been planned to commemorate the tragic event. Until 1918, the Italian Trentino - Alto Adige region was under the Austro - Hungarian Empire and represented one of the most crucial and bloody war front between the Austrian and Italian territories. The region borders were constellated of military fortresses, theatre of battles between the two opposite troops. Unfortunately, most of these military buildings are now ruined and their architectures can be hardly appreciated. The paper presents the initial results of the VAST project (VAlorizzazione Storia e Territorio - Valorization of History and Landscape), that aims to digitally reconstruct the forts located on the plateaus of Luserna, Lavarone and Folgaria. An integrated methodology has been adopted to collect and employ all possible source of information in order to derive precise and photo-realistic 3D digital representations of WWI forts.

    2008-01-01

    Military training, soil texture, and ground cover influence ant communities at Fort Benning, a military installation in west-central Georgia. We sampled 81,237 ground-dwelling ants (47 species in 20 genera) with pitfall traps at 40 sites on a continuum from nearly pristine forest to highly disturbed training areas. We also measured 15 environmental variables related to vegetation and soil. Sites disturbed by military training had fewer trees, less canopy cover, more bare ground, and more compact soils with shallower A-horizons than comparable undisturbed sites. Pheidole bicarinata, Dorymyrmex smithi, and Pogonomyrmex badius dominated the most highly disturbed sites. Competitively submissive myrmicines, such as Aphaenogaster and Crematogaster, and formicines, such as Camponotus and Formica, were abundant in the undisturbed sites. Solenopsis invicta occurred in all but the least disturbed sites. Ant community composition was a useful indicator of disturbance at Fort Benning.

    This paper discusses NRC approval for the first dry vault storage system to be submitted for nonsite specific design approval. It describes the first site specific application of the FW/GEC modular vault dry store (MVDS) for the Public Service of Colorado---Fort St. Vrain site. The decision to permanently shut down the Fort St. Vrain high temperature gas-cooled reactor provides the need to store on site 1,482 irradiated fuel blocks and a quantity of other reactor core components categorized as greater than Class C wastes. The MVDS system has been selected for the safe storage of these items in a facility designed to receive, store and discharge fuel to the repository totally independent from the original reactor facilities.

  9. Nondestructive examination of 51 fuel and reflector elements from Fort St. Vrain Core Segment 1

    International Nuclear Information System (INIS)

    Fifty-one fuel and reflector elements irradiated in core segment 1 of the Fort St. Vrain High-Temperature Gas-Cooled Reactor (HTGR) were inspected dimensionally and visually in the Hot Service Facility at Fort St. Vrain in July 1979. Time- and volume-averaged graphite temperatures for the examined fuel elements ranged from approx. 4000 to 7500C. Fast neutron fluences varied from approx. 0.3 x 1025 n/m2 to 1.0 x 1025 n/m2 (E > 29 fJ)/sub HTGR/. Nearly all of the examined elements shrank in both axial and radial dimensions. The measured data were compared with strain and bow predictions obtained from SURVEY/STRESS, a computer code that employs viscoelastic beam theory to calculate stresses and deformations in HTGR fuel elements

    In FY1999, Pacific Northwest National Laboratory conducted an energy efficiency campaign for residential housing at the Fort Lewis Army Installation near Tacoma, Washington. Preliminary weather-corrected calculations show energy savings of 10{percent} from FY98 for energy use in family housing. This exceeded the project's goal of 3{percent}. The work was funded by the U.S. DOEs Federal Energy Management Program (FEMP), Office of Energy Efficiency and Renewable Energy. The project adapted FEMP's national ``You Have the Power Campaign'' at the local level, tailoring it to the military culture. The applied research project was designed to demonstrate the feasibility of tailored, research-based strategies to promote energy conservation in military family housing. In contrast to many energy efficiency efforts, the campaign focused entirely on actions residents could take in their own homes, as opposed to technology or housing upgrades. Behavioral change was targeted because residents do not pay their own utility bills; thus other motivations must drive personal energy conservation. This campaign augments ongoing energy savings from housing upgrades carried out by Fort Lewis. The campaign ran from September 1998 through August 1999. The campaign strategy was developed based on findings from previous research and on input from residents and officials at Fort Lewis. Energy use, corrected to account for weather differences, was compared with the previous year's use. Survey responses from 377 of Fort Lewis residents of occupied housing showed that the campaign was moderately effective in promoting behavior change. Of those who were aware of the campaign, almost all said they were now doing one or more energy-efficient things that they had not done before. Most people were motivated by the desire to do the right thing and to set a good example for their children. They were less motivated by other factors.

    Full Text Available In maxillary Le Fort I type osteotomy the detachment of the nasal mucosa should be done carefully. Piezoelectric surgery contributed much to increase the safety of osteotomies, despite the initial advantage of minimizing the risk of injury in nervous tissue, mainly in bilateral sagittal split osteotomy; we use the piezoelectric device for the initial detachment of the nasal mucosa in the maxillary osteotomy.

  17. Fort Lewis natural gas and fuel oil energy baseline and efficiency resource assessment

    International Nuclear Information System (INIS)

    The mission of the US Department of Energy (DOE) Federal Energy Management Program (FEMP) is to lead the improvement of energy efficiency and fuel flexibility within the federal sector. Through the Pacific Northwest Laboratory (PNL), FEMP is developing a fuel-neutral approach for identifying, evaluating, and acquiring all cost-effective energy projects at federal installations; this procedure is entitled the Federal Energy Decision Screening (FEDS) system. Through a cooperative program between FEMP and the Army Forces Command (FORSCOM) for providing technical assistance to FORSCOM installations, PNL has been working with the Fort Lewis Army installation to develop the FEDS procedure. The natural gas and fuel oil assessment contained in this report was preceded with an assessment of electric energy usage that was used to implement a cofunded program between Fort Lewis and Tacoma Public Utilities to improve the efficiency of the Fort's electric-energy-using systems. This report extends the assessment procedure to the systems using natural gas and fuel oil to provide a baseline of consumption and an estimate of the energy-efficiency potential that exists for these two fuel types at Fort Lewis. The baseline is essential to segment the end uses that are targets for broad-based efficiency improvement programs. The estimated fossil-fuel efficiency resources are estimates of the available quantities of conservation for natural gas, fuel oils number-sign 2 and number-sign 6, and fuel-switching opportunities by level of cost-effectiveness. The intent of the baseline and efficiency resource estimates is to identify the major efficiency resource opportunities and not to identify all possible opportunities; however, areas of additional opportunity are noted to encourage further effort

    International Nuclear Information System (INIS)

    The nuclear power plant at Fort St. Vrain, with the world's only operating HTR, reached full-load operation on November 6, 1981. Operating tests at full load were carried out for three days, i.e. until November 9. The power plant was then shut down for maintenance and for reconstruction of the helium compressor auxiliary system. All HTR components and systems worked reliably during full-load operation. The trial operation has helped to advance commercial HTR technology. (orig.)

  3. Energy saving potential of residential HVAC options at Fort Irwin, California

    Energy Technology Data Exchange (ETDEWEB)

    Hadley, D.L.; Stucky, D.J.

    1995-03-01

    The Pacific Northwest Laboratory (PNL) evaluated heating and cooling system options for existing family housing at Fort Irwin, California. The purpose of this work was to quantify the energy conservation potential of alternative system types and to identify the most cost-effective technology available. The conventional residential heating/cooling systems at Fort Irwin are separate propane forced-air furnaces and central air conditioners. The options examined included air- and ground-source heat pumps, a natural gas furnace with central air conditioning, and a natural-gas-fired heat pump. The most cost-effective technology applicable to Fort Irwin was found to be the high-efficiency ground-source heat pumps. If all conventional units were replaced immediately, the net energy savings would be 76,660 MBtu (80.9 TJ) per year and a reduction in electrical demand of approximately 15,000 kW-month. The initial investment for implementing this technology would be approximately $7.1 million, with a savings-to-investment ratio of 1.74.

    The aim of this study was to evaluate the maxillary stability in patients who had undergone Le Fort I osteotomy with propeller graft and mandibular sagittal split ramus osteotomy for correction of maxillary asymmetry. This was a retrospective study on 15 facial asymmetry patients (7 men, 8 women: 22.2 years) requiring surgical correction at the preoperative (T0), immediately postoperative (T1) and 6 months after surgery (T2) stages. To evaluate the skeletal stability, computed tomography (CT) superimposition was used, and skeletal landmarks were measured and compared from the superimposed images according to an x, y, z coordinate system. The skeletal changes at each stage (ΔT1-T0 and ΔT2-T1) were compared by paired t-test (P<0.05). The obtained data on the skeletal changes immediately postoperatively to 6-month follow-up (ΔT2-T1) showed that the Le Fort I osteotomy with propeller graft had effected stable maxillary skeletal stability at the maxillary measurement points (posterior nasal spine (PNS ), nasopalatine canal, U3 crown tip, U3 root apex, and U6 furcation). These results suggested that in cases of facial asymmetry where the upper tooth exposure is proper and anterior-posterior movement of the maxilla is not much required, Le Fort I osteotomy with propeller graft is an effective method for stable canting correction.

  5. How confident is Fort McKay that industry can reclaim oil sand development

    International Nuclear Information System (INIS)

    This presentation described how traditional environmental knowledge (TEK) can provide valuable information for both the reclamation design and assessment of oil sand development in Fort McKay. Conservation is valued by the Fort McKay First Nations communities who claim that current reclamation methods are too slow, and that the land is not being brought back to its original use with the uniqueness of the boreal landscape. Elders have noted that each year the water level in the Athabasca River is lower. The blowing tailings and coke dust are causing trees to dye and driving animals away. There is concern that the animals that remain may not be safe to eat. The Fort McKay First Nation community has stated that it will view reclamation as a success only when it functions with proof over many generations. The major concerns include: salt in the water draining from reclaimed areas; salt in the soils of reclaimed area; muskeg cannot be recreated; and, the issue of whether cranberry, blueberry and streambank forest areas can be recreated, along with traditional medicinal plants. Other concerns include the loss of rivers such as the Beaver Creek and Tar River, and that the water in reclaimed areas may not be suitable for animals to live in or to drink. tabs., figs

  6. Impacts of prescribed fire on ecosystem C and N cycles at Fort Benning Installation, Georgia

    2007-12-01

    A critical challenge for the land managers at military installation is to maintain the ecological sustainability of natural resources while meeting the needs of military training. Prescribed ground fire as a land management practice has been used to remove the ground layer plants at Fort Benning for two purposes: to facilitate access for military training, and to maintain and restore fire-adapted longleaf pine communities that are critical habitat for the federally endangered red-cockaded woodpecker (Picoides borealis). Nevertheless, the impacts of prescribed fire on ecosystem processes and health are not well-understood and quantified at the plot to regional scales. Frequent fire may result in ecosystem nitrogen (N) deficiency due to repeated N loss through combustion, volatilization, and leaching, threatening ecosystem sustainability at Fort Benning. On the other hand, N loss may be offset by enhanced symbiotic N2 fixation since fire favors herbaceous legumes by scarifying legume seeds and stimulating germination. Quantifying the impacts of prescribed fire on ecosystem carbon (C) and N cycles is further complicated by interactions and feedbacks among burning, nitrogen inputs, other land use practices (e.g. tree thinning or clear-cutting), and soil properties. In this study, we used the Erosion-Deposition-Carbon Model (EDCM), a process-based biogeochemical model, to simulate C and N dynamic at Fort Benning under different combinations of fire frequency, fire intensity, nitrogen deposition, legume nitrogen input, forest harvesting, and soil sand content. Model simulations indicated that prescribed fire led to nitrogen losses from ecosystems at Fort Benning, especially with high intensity and high frequency fires. Forest harvesting further intensified ecosystem nitrogen limitation, leading to reduced biophysical potential of C sequestration. The adverse impacts of prescribed fire and forest harvesting on C and N cycles were much higher in more sandy soil than in

    2015-04-01

    Lithuania is famous for its abundant, picturesque hill forts and castle mounds of natural origin. In Lithuania as well as in whole Europe the fortified hills were used as the society dwelling place since the beginning of the Late Bronze Age. Their importance increased when Livonian and Teutonic Orders directed a series of military campaigns against Lithuania with the aim of expansion of Christianity in the region at the end of 1st millennium AD, and they were intensively used till the beginning of the 15th c. when most of them were burned down during fights with the Orders or just abandoned due to the changing political and economical situation. What types of the geodiversity were used for fortified dwellings? The choice in a particular area depended on a variety of geomorphology left behind the retreating ice sheets. High spots dominating their surroundings were of prime interest. In E and SE Lithuania, the Baltic Upland hills marking the eastern margin of the last Weichselian glacier hosted numerous fortified settlements from the end of 2nd millennium BC to the Medieval Ages (Narkunai, Velikuskes etc). In W Lithuania, plateau-like hills of the insular Samogitian Upland had been repeatedly fortified from the beginning of 1st millennium AD to the 14th century (Satrija, Medvegalis etc). Chains of hill forts and castle mounds feature the slopes of glaciofluvial valleys of Nemunas, Neris and other rivers where the slopes were dissected by affluent rivulets and ravines and transformed into isolated, well protected hills (Kernave, Punia, Veliuona etc). Peninsulas and headlands formed by the erosion of fluvial and lacustrine deposits were used in the lowlands, e.g. in central and N Lithuania (Paberze, Mezotne etc). How much the landscape was modified for defense purposes? Long-term erosion and overgrowing vegetation damaged the former fortified sites, however some remains and the archeological excavations allowed their reconstruction.

    The need for affordable energy sources is acute in rural communities of Alaska where costly diesel fuel must be delivered by barge or plane for power generation. Additionally, the transport, transfer, and storage of fuel pose great difficulty in these regions. Although small-scale energy development in remote Arctic locations presents unique challenges, identifying and developing economic, local sources of energy remains a high priority for state and local government. Many areas in rural Alaska contain widespread coal resources that may contain significant amounts of coalbed methane (CBM) that, when extracted, could be used for power generation. However, in many of these areas, little is known concerning the properties that control CBM occurrence and production, including coal bed geometry, coalbed gas content and saturation, reservoir permeability and pressure, and water chemistry. Therefore, drilling and testing to collect these data are required to accurately assess the viability of CBM as a potential energy source in most locations. In 2004, the U.S. Geological Survey (USGS) and Bureau of Land Management (BLM), in cooperation with the U.S. Department of Energy (DOE), the Alaska Department of Geological and Geophysical Surveys (DGGS), the University of Alaska Fairbanks (UAF), the Doyon Native Corporation, and the village of Fort Yukon, organized and funded the drilling of a well at Fort Yukon, Alaska to test coal beds for CBM developmental potential. Fort Yukon is a town of about 600 people and is composed mostly of Gwich'in Athabascan Native Americans. It is located near the center of the Yukon Flats Basin, approximately 145 mi northeast of Fairbanks.

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

    Energy Technology Data Exchange (ETDEWEB)

    Lawrence M. Monson

    2003-06-30

    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

    This open, multicenter study investigated the tolerability and efficacy of a new tablet formulation of Echinacea purpurea extract (Echinaforce Forte; A. Vogel, Bioforce AG, Roggwil, Switzerland) in 80 subjects actively involved in sports. Most investigators (97.5%) rated the treatment as having "very good" or "good" tolerability. About 75% of patients and investigators rated its efficacy during a common cold as "very good" or "good," and 71% of subjects were free of cold episodes. This study is the first to suggest that Echinaforce is effective in the prophylaxis, as well as the treatment, of the common cold in persons who actively participate in sports. PMID:17142219

    2012-01-01

    Digital flood-inundation maps for a 9-mile reach of the St. Marys River that extends from South Anthony Boulevard to Main Street at Fort Wayne, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Fort Wayne. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site, depict estimates of the areal extent of flooding corresponding to selected water levels (stages) at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. Current conditions at the USGS streamgages in Indiana may be obtained from the National Water Information System: Web Interface. In addition, the information has been provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system. The NWS forecasts flood hydrographs at many places that are often collocated at USGS streamgages. That forecasted peak-stage information, also available on the Internet, may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, water-surface profiles were simulated for the stream reach by means of a hydraulic one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge relation at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. The hydraulic model was then used to simulate 11 water-surface profiles for flood stages at 1-ft intervals referenced to the streamgage datum and ranging from bankfull to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data) in order to delineate the area flooded at each water level. A flood inundation map was generated for each water-surface profile stage (11 maps in all) so that for any given flood stage users will be

    During the start-up test programme, the Fort St. Vrain plant control systems and safety control systems have been tested and adjusted to the operating requirements. So far, they have worked satisfactorily in the range up to 10% of the rated power in fully automatic operation. Experiments and some actual incidents have shown that the control function is satisfactory in case of turbine failure, reactor scram, and coolant loop insulation failure. Transient states in normal operation, e.g. changes of load, are controlled with negligible deviations from the rated values. (orig./GL)

    International Nuclear Information System (INIS)

    In October 1977, during the rise to power test program, the Fort St. Vrain high temperature gas-cooled reactor experienced the first of 37 fluctuation events involving primary coolant outlet temperature, nuclear detector signals, steam generator module gas inlet temperature and steam generator module main and reheat steam temperatures. In a 3 year investigation it was determined that the apparent cause of the fluctuations was movements of core components accompanied by periodic changes in bypass flows and crossflows of primary coolant helium. Installation of region constraint devices has eliminated fluctuations, but a single small primary coolant helium core outlet temperature redistribution is experienced routinely during rise to power.

    In field tests in a fossil-fueled facility, performed concurrently with Fort St. Vrain's construction, data indicated that the helium circulator design was well suited to provide primary coolant circulation for the high temperature gas-cooled reactor. After plant installation, primarily during the hot functional tests, a number of time-consuming delays developed caused by cavitation damage on circular speed valves, cavitation and fatigue damage on auxiliary water turbine buckets, water turbine nozzle erosion, static shutdown seal cracks and circulator primary closure helium leakage. After extensive analysis and testing, all of these problems were corrected. Circulators have performed satisfactorily at levels up to 70% of rated power. (Auth.)

    Science.gov (United States)

    Wallace, Alan R.; Machette, Michael N.

    2008-01-01

    The map area includes Fort Garland, Colo., and the surrounding area, which is primarily rural. Fort Garland was established in 1858 to protect settlers in the San Luis Valley, then part of the Territory of New Mexico. East of the town are the Garland mesas (basalt-covered tablelands), which are uplifted as horsts with the Central Sangre de Cristo fault zone. The map also includes the northern part of the Culebra graben, a deep structural basin that extends from south of San Luis (as the Sanchez graben) to near Blanca, about 8 km west of Fort Garland. The oldest rocks exposed in the map area are early Proterozic basement rocks (granites in Ikes Creek block) that occupy an intermediate structural position between the strongly uplifted Blanca Peak block and the Culebra graben. The basement rocks are overlain by Oligocene volcanic and volcaniclastic rocks of unknown origin. The volcanic rocks were buried by a thick sequence of basin-fill deposits of the Santa Fe Group as the Rio Grande rift formed about 25 million years ago. The Servilleta Basalt, a regional series of 3.7?4.8 Ma old flood basalts, was deposited within sediment, and locally provides a basis for dividing the group into upper and lower parts. Landslide deposits and colluvium that rest on sediments of the Santa Fe Group cover the steep margins of the mesas. Exposures of the sediment beneath the basalt and within the low foothills east of the Central Sangre de Cristo fault zone are comprised of siltstones, sandstones, and minor fluvial conglomerates. Most of the low ground surrounding the mesas and in the graben is covered by surficial deposits of Quaternary age. The alluvial deposits are subdivided into three Pleistocene-age units and three Holocene-age units. The oldest Pleistocene gravel (unit Qao) is preserved as isolated remnants that cap high surfaces north and east of Fort Garland. The primary geologic hazards in the map area are from earthquakes, landslides, and localized flooding. The Central

  5. Primary coolant chemistry of the Peach Bottom and Fort St. Vrain high temperature gas-cooled reactors

    International Nuclear Information System (INIS)

    The chemical impurities in the primary coolants of the Peach Bottom and Fort St. Vrain reactors are discussed. The impurity mixtures in the two plants were quite different because the sources of the impurities were different. In the Peach Bottom reactor, the impurities were dominated by H2 and CH4, which are decomposition products of oil. In the Fort St. Vrain reactor, there were high levels of CO, CO2, and H2O. Although oil ingress at Peach Bottom created carbon deposits on virtually all surfaces, its effect on reactor operation was negligible. Slow outgassing of water from the thermal insulation at Fort St. Vrain caused delays in reactor startup. The overall graphite oxidation in both plants was negligible. (author)

    A geophysical investigation was carried out to locate and characterize the remains of the Sancti Spiritus Fort, the first European settlement in the South Cone of America (1527-1529). In an initial stage, we used three complementary methods, ground penetrating radar, multifrequency electromagnetic induction and dipole-dipole electric profiling, to increase the possibility of detecting the structures of the Fort whose physical properties were expected to be similar to those of the surrounding soil, as they were constructed with raw earth probably extracted from it. From different views of the data, a number of electromagnetic signals apparently related to these structures were identified. Test excavations confirmed these hypotheses and showed that the structures were poorly preserved. Furthermore, they were almost indistinguishable through direct inspection of the excavated sections of soil, and very difficult to track. Therefore, in a second stage of geophysical studies, we acquired high-density grids of GPR data at relevant areas, looking for more detailed information about the structures. The results of these studies allowed to determine with precision their continuity through the site and also to interpret a number of areas which had remained unclear from the first survey. Extensive archaeological excavations were designed from the geophysical maps and carried out. From them, the geophysical interpretations were fully confirmed, and the presence of structural elements of previous and later native settlements was established.

  8. Preliminary assessment report for National Guard Training Center, Georgia Army National Guard, Fort Stewart, Georgia

    International Nuclear Information System (INIS)

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Georgia Army National Guard (GAARNG) facility near Hinesville, Georgia, known as the National Guard Training Center (NGTC). Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a priority basis for completing corrective actions (where necessary) in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining previous site activities, types and quantities of hazardous substances utilized, and potential pathways by which contamination could affect public health and the environment. The scope of this assessment is limited to the facilities and past activities contained within the NGTC. Preliminary assessment site score sheet information is also provided for the NGTC. However, this assessment report is intended to be read in conjunction with a previous IRP assessment of Fort Stewart completed in 1992 (USATHAMA 1992) and to provide comprehensive information on the NGTC area for incorporation with information contained in that previous assessment for the entirety of Fort Stewart

    We examined home range behavior of female feral pigs (Sus scrofa) in a heavily hunted population on Fort Benning Military Reservation in west-central Georgia, USA. We used Global Positioning System location data from 24 individuals representing 18 sounders (i.e., F social groups) combined with markrecapture and camera-trap data to evaluate evidence of territorial behavior at the individual and sounder levels. Through a manipulative experiment, we examined evidence for an inverse relationship between population density and home range size that would be expected for territorial animals. Pigs from the same sounder had extensive home range overlap and did not have exclusive core areas. Sounders had nearly exclusive home ranges and had completely exclusive core areas, suggesting that female feral pigs on Fort Benning were territorial at the sounder level but not at the individual level. Lethal removal maintained stable densities of pigs in our treatment area, whereas density increased in our control area; territory size in the 2 areas was weakly and inversely related to density of pigs. Territorial behavior in feral pigs could influence population density by limiting access to reproductive space. Removal strategies that 1) match distribution of removal efforts to distribution of territories, 2) remove entire sounders instead of individuals, and 3) focus efforts where high-quality food resources strongly influence territorial behaviors may be best for long-term control of feral pigs.

    The U.S. Army Forces Command (FORSCOM) has tasked the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory, to identify, evaluate, and assist in acquiring all cost-effective energy projects at Fort Irwin. This is part of a model program that PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the FORSCOM Fort Irwin facility located near Barstow, California. It is a companion report to Volume 1, Executive Summary, and Volume 2, Baseline Detail. The results of the analyses of EROs are presented in 16 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, along with a table detailing information on the installed cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. A description of the evaluation methodologies and technical and cost assumptions is also provided for each ERO. Summary tables present the cost-effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis indicating the net present valve (NPV) and savings-to-investment ratio (SIR) of each ERO.

    2014-01-01

    Recent analyses suggest that the big brown bat (Eptesicus fuscus) may be less of a beetle specialist (Coleoptera) in the western United States than previously thought, and that its diet might also vary with temperature. We tested the hypothesis that big brown bats might opportunistically prey on moths by analyzing insect fragments in guano pellets from 30 individual bats (27 females and 3 males) captured while foraging in Fort Collins, Colorado, during May, late July–early August, and late September 2002. We found that bats sampled 17–20 May (n = 12 bats) had a high (81–83%) percentage of volume of lepidopterans in guano, with the remainder (17–19% volume) dipterans and no coleopterans. From 28 May–9 August (n = 17 bats) coleopterans dominated (74–98% volume). On 20 September (n = 1 bat) lepidopterans were 99% of volume in guano. Migratory miller moths (Euxoa auxiliaris) were unusually abundant in Fort Collins in spring and autumn of 2002 and are known agricultural pests as larvae (army cutworms), suggesting that seasonal dietary flexibility in big brown bats has economic benefits.

    Four species of ticks known to parasitize humans (Amblyomma americanum (lone star tick), Dermacentor variabilis (American dog tick), Amblyomma maculatum (Gulf Coast tick), and Ixodes scapularis (black-legged tick)) were collected at Joint Base Langley-Eustis, Fort Eustis, Virginia during 2009. These ticks were tested individually (adults and nymphs) and in pools of 15 (larvae) for pathogens of public health importance within the genera: Rickettsia, Borrelia, and Ehrlichia, by quantitative real-time polymerase chain reaction (qPCR) assays and, where appropriate, multilocus sequence typing (MLST). Of the 340 A americanum ticks tested, a minimum of 65 (19%), 4 (1%), 4 (1%), and one (<1%) were positive for Rickettsia amblyommii, B lonestari, E ewingii and E chaffeensis, respectively. One of 2 (50%) A maculatum ticks collected was found to be positive for R parkeri by MLST and qPCR analyses. All 33 D variabilis ticks were negative for evidence of rickettsial infections. Likewise, no pathogenic organisms were detected from the single Ixodes scapularis tick collected. Pathogenic rickettsiae and ehrlichiae are likely emerging and cause under-recognized diseases, which threaten people who live, work, train, or otherwise engage in outdoor activities at, or in the vicinity of, Fort Eustis, Virginia.

    1993-09-01

    One of the alternatives to the disposal of the Fort St. Vrain (FSV) reactor spent nuclear fuel involves the separation of the fuel rods composed of compacts from the graphite fuel block assembly. After the separation of these two components, the empty graphite fuel blocks would be disposed of as a low level waste (provided the appropriate requirements are met) and the fuel compacts would be treated as high level waste material. This report deals with the mechanical separation aspects concerning physical disassembly of the FSV graphite fuel element into the empty graphite fuel blocks and fuel compacts. This report recommends that a drilling technique is the preferred choice for accessing the, fuel channel holes and that each hole is drilled separately. This report does not cover any techniques or methods to separate the triso fuel particles from the graphite matrix of the fuel compacts.

    International Nuclear Information System (INIS)

    Fifty-four fuel and reflector elements irradiated in core segment 2 of the Fort St. Vrain high-temperature gas-cooled reactor (HTGR) were nondestructively examined. The time- and volume-averaged graphite irradiation temperatures for the elements ranged from approx. 3500 to 7500C. The element-averaged fast neutron fluences ranged from approx. 0.2 to 1.6 x 1025 n/m2 (E > 29 fJ)/sub HTGR/. The elements, except for two fuel elements in which single localizeed cracks developed during irradiation, were in excellent condition. No evidence was observed of significant graphite oxidation or mechanical interaction beween elements. The cracks in the two elements did not affect their performance or handling. These elements were, otherwise, in excellent condition. Nearly all elements shrank in both the axial and radial directions, but the dimensional changes were relatively small

  13. Success story: Interagency cooperation on an RI/FS at Fort Lewis, Washington

    International Nuclear Information System (INIS)

    From February 1992 through May 1993, an RI/FS was conducted at the Fort Lewis Military Reservation near Tacoma, Washington on two suspected contaminated sites, an old municipal landfill (Landfill No. 4) and an abandoned Solvent Refined Coal Pilot Plant (SRCPP), an experimental facility which extracted petroleum products from coal. Intensive planning, cooperation and excellent working relationships between the parties (Army, EPA, Ecology, and Corps of Engineers) enabled completion of the studies in just 16 months, without any adjustment to the project submittal schedule. The flexibility and technical expertise of the consultant (AGI) proved invaluable to solve numerous technically challenges presented by the project. During the investigation, soil and ground water sampling and analysis was undertaken for a wide variety of contaminants. Contaminants discovered at the sites which exceeded regulatory levels were trichloroethylene (TCE) and vinyl chloride in ground water at the landfill and polycyclic aromatic hydrocarbons (PAHs) in soil at the SRCPP

    A tethersonde system was deployed at Fort Cobb, Oklahoma during the Cloud and Land Surface Interaction Campaign (CLASIC) June 8-24 2007 with the objective of characterizing the diurnal cycle of lower boundary layer structure up to 500 m including wind, pressure, temperature, humidity as well as CO2 profiles over harvested wheat. One unique feature of this data set is that includes fair weather, pre-storm and post-storm conditions for a record monthly rainfall in Oklahoma, in excess of 300 mm at the site. Here, we discuss specifically the diurnal cycle of (potential temperature) and q (specific humidity) and overall boundary layer structure during the duration of the field campaign with an emphasis on conditions before and after one major rain event. Preliminary regional estimates of surface roughness and friction velocity, and sensible heat flux and latent heat flux are also presented.

    Hotz, Preston E.

    1973-01-01

    Blueschist is plentiful in the Yreka-Fort Jones area, eastern Klamath Mountains, adjacent to a belt of serpentinite that marks the boundary between two fundamental lithologic units, an eastern belt of early Paleozoic sedimentary and metamorphic rocks, and a western greenstone-chert assemblage of late Paleozoic and Triassic(?) age. The blueschists, which contain lawsonite and glaucophane or crossite, occur with phyllitic quartzite and siliceous phyllite of the Stuart Fork Formation, which is overthrust northwestward on the greenstone-chert terrane. The blueschist facies metamorphism probably was synchronous with Middle and Late Jurassic metamorphism of the Stuart Fork Formation. The blueschist-serpentinite terrane possibly marks the site of collision between the eastern Klamath plate and an oceanic western Paleozoic and Triassic plate.

    This study was carried out on volunteers to evaluate a newly developed interactive software package aimed at informing prospective Le Fort I osteotomy patients regarding the surgical technique and possible complications. The aim of the study was to compare two methods of information delivery; a multi-media tablet device delivering both graphic and verbal information, and an audio device delivering essentially the same information in verbal form only. The null hypothesis was that there would be no difference between the efficiencies of the two methods. The subjects' ability to recall the information delivered by both devices was assessed using a questionnaire. The tablet device participants scored an average of 15.48 points, while the audio device participants scored an average of 268 points. The difference was statistically significant (p < 0.001), suggesting that the multi-media tablet device was more effective method. PMID:24534682

  1. The Fort St. Vrain high temperature gas-cooled reactor. Pt. 5

    International Nuclear Information System (INIS)

    The Fort St. Vrain primary and secondary coolant systems have given satisfactory performance during the rise power test program with the tests being terminated at the current maximum allowable thermal reactor power of 70% of rated. Because of a regenerative heat problem in the steam generators, rated conditions of 10000F main and hot reheat steam temperatures, predicted to occur at 25% power, were not reached until 68%. The regenerative heat problem also forced overblowing of the core with primary coolant helium which resulted in higher fuel temperatures than predicted, lower core primary coolant outlet temperatures and higher core primary coolant inlet temperatures. Data suggest that all parameters will be at rated conditions at 80-100% power. A small steam generator tubing leak was detected by the primary coolant moisture monitors of the plant protective system. It was located by covergas techniques and repaired by plugging the leaking feedwater and steam subheaders external to the reactor.(orig.)

  4. CHAP-2 heat-transfer analysis of the Fort St. Vrain reactor core

    International Nuclear Information System (INIS)

    The Los Alamos National Laboratory is developing the Composite High-Temperature Gas-Cooled Reactor Analysis Program (CHAP) to provide advanced best-estimate predictions of postulated accidents in gas-cooled reactor plants. The CHAP-2 reactor-core model uses the finite-element method to initialize a two-dimensional temperature map of the Fort St. Vrain (FSV) core and its top and bottom reflectors. The code generates a finite-element mesh, initializes noding and boundary conditions, and solves the nonlinear Laplace heat equation using temperature-dependent thermal conductivities, variable coolant-channel-convection heat-transfer coefficients, and specified internal fuel and moderator heat-generation rates. This paper discusses this method and analyzes an FSV reactor-core accident that simulates a control-rod withdrawal at full power

    Full Text Available This article reports the case of a 19-year-old young man with Class III malocclusion and posterior crossbite with concerns about temporomandibular disorder (TMD, esthetics and functional problems. Surgical-orthodontic treatment was carried out by decompensation of the mandibular incisors and segmentation of the maxilla in 4 pieces, which allowed expansion and advancement. Remission of the signs and symptoms occurred after surgical-orthodontic intervention. The maxillary dental arch presented normal transverse dimension. Satisfactory static and functional occlusion and esthetic results were achieved and remained stable. Three years after the surgical-orthodontic treatment, no TMD sign or symptom was observed and the occlusal results had not changed. When vertical or horizontal movements of the maxilla in the presence of moderate maxillary constriction are necessary, segmental LeFort I osteotomy can be an important part of treatment planning.

  8. Vegetation diversity and biomass : response to oil sand tailings disposal in Fort McMurray, Alberta

    International Nuclear Information System (INIS)

    While covering the bottom of constructed wetlands with a layer of oil sands tailings has been proposed as a means of disposal, the salts and naphthenic acids (NA) in tailings may have negative impacts on wetland vegetation development. This study was conducted to determine if wetlands constructed with oil sands tailings have a lower vegetation diversity and biomass than constructed wetlands that are not amended with tailings. The effects of NA and salinity on the vegetation in natural, constructed, and tailings-impacted wetlands were evaluated in 30 sites in the Fort McMurray region. Results of the study indicate that the presence of tailings negatively impacted both vegetation diversity and biomass. Salinity was identified as the primary causal factor.

    1998-03-01

    This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

    The dual-polarization X-band radar network developed by the U.S. National Science Foundation Engineering Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) has shown great advantages for observing and prediction of hazardous weather events in the lower atmosphere (1-3 km above ground level). The network is operating though a scanning methodology called DCAS, distributed collaborative adaptive sensing, which is designed to focus on particular interesting regions of the atmosphere and disseminate information for decision-making to multiple end-users, such as emergency managers and policy analysts. Since spring 2012, CASA and the North Central Texas Council of Governments (NCTCOG) have embarked the development of Dallas Fort Worth (DFW) urban remote sensing network, including 8-node of dual-polarization X-band radars, in the populous DFW Metroplex (pop. 6.3 million in 2010). The main goal of CASA DFW urban demonstration network is to protect the safety and prosperity of humans and ecosystems through research activities that include: 1) to demonstrate the DCAS operation paradigm developed by CASA; 2) to create high-resolution, three-dimensional mapping of the meteorological conditions; 3) to help the local emergency managers issue impacts-based warnings and forecasts for severe wind, tornado, hail, and flash flood hazards. The products of this radar network will include single and multi-radar data, vector wind retrieval, quantitative precipitation estimation and nowcasting, and numerical weather predictions. In addition, the high spatial and temporal resolution rainfall products from CASA can serve as a reliable data input for distributed hydrological models in urban area. This paper presents the information and communication link between radars, rainfall product generation, hydrologic model link and end user community in the Dallas Fort Worth Urban Network.

The excavation enabled us to clarify the function of the fort, built in the 2nd half of the 12th century at a time when Chinon was the administrative centre of the continental possesions of the Plantagenet King of England. From a military point of view, it formed an advanced fortification protecting the main castle, within a structure that Richard the Lionheart would apply to the Chayeau Gaillard. Inside, some vast buildings made up the dwellings, designed perhaps initially to house the royal chanceller.

  12. Modeling Soil Quality Thresholds to Ecosystem Recovery at Fort Benning, Georgia, USA

    Garten Jr., C.T.

    2004-03-08

    The objective of this research was to use a simple model of soil C and N dynamics to predict nutrient thresholds to ecosystem recovery on degraded soils at Fort Benning, Georgia, in the southeastern USA. The model calculates aboveground and belowground biomass, soil C inputs and dynamics, soil N stocks and availability, and plant N requirements. A threshold is crossed when predicted soil N supplies fall short of predicted N required to sustain biomass accrual at a specified recovery rate. Four factors were important to development of thresholds to recovery: (1) initial amounts of aboveground biomass, (2) initial soil C stocks (i.e., soil quality), (3) relative recovery rates of biomass, and (4) soil sand content. Thresholds to ecosystem recovery predicted by the model should not be interpreted independent of a specified recovery rate. Initial soil C stocks influenced the predicted patterns of recovery by both old field and forest ecosystems. Forests and old fields on soils with varying sand content had different predicted thresholds to recovery. Soil C stocks at barren sites on Fort Benning generally lie below predicted thresholds to 100% recovery of desired future ecosystem conditions defined on the basis of aboveground biomass (18000 versus 360 g m{sup -2} for forests and old fields, respectively). Calculations with the model indicated that reestablishment of vegetation on barren sites to a level below the desired future condition is possible at recovery rates used in the model, but the time to 100% recovery of desired future conditions, without crossing a nutrient threshold, is prolonged by a reduced rate of forest growth. Predicted thresholds to ecosystem recovery were less on soils with more than 70% sand content. The lower thresholds for old field and forest recovery on more sandy soils are apparently due to higher relative rates of net soil N mineralization in more sandy soils. Calculations with the model indicate that a combination of desired future

    The El Paso County Geothermal Project at Fort Bliss was an effort to determine the scale and scope of geothermal resources previously identified on Fort Bliss’ McGregor Range in southern Otero County, New Mexico. The project was funded with a $5,000,000 grant to El Paso County from the U.S. Department of Energy (DOE) as part of the American Recovery and Reinvestment Act of 2009 and a $4,812,500 match provided by private sector partners. The project was administered through the DOE Golden Field Office to awardee El Paso County. The primary subcontractor to El Paso County and project Principal Investigator - Ruby Mountain Inc. (RMI) of Salt Lake City, Utah - assembled the project team consisting of Evergreen Clean Energy Management (ECEM) of Provo, Utah, and the Energy & Geoscience Institute at the University of Utah (EGI) in Salt Lake City, UT to complete the final phases of the project. The project formally began in May of 2010 and consisted of two preliminary phases of data collection and evaluation which culminated in the identification of a drilling site for a Resource Confirmation Well on McGregor Range. Well RMI 56-5 was drilled May and June 2013 to a depth of 3,030 ft. below ground level. A string of slotted 7 inch casing was set in 8.75 inch hole on bottom fill at 3,017 ft. to complete the well. The well was drilled using a technique called flooded reverse circulation, which is most common in mineral exploration. This technique produced an exceptionally large and complete cuttings record. An exciting development at the conclusion of drilling was the suspected discovery of a formation that has proven to be of exceptionally high permeability in three desalinization wells six miles to the south. Following drilling and preliminary testing and analysis, the project team has determined that the McGregor Range thermal anomaly is large and can probably support development in the tens of megawatts.

    FLODIS is a combined heat transfer and fluid flow analysis calculation written specifically for the core of the Fort St. Vrain reactor. It is a lumped-node representation of the 37 refueling regions in the active core. Heat conduction to the coolant and in the axial direction is represented; however, the effect of conduction between refueling regions is not included. The calculation uses the specified operating conditions for the reactor at power to determine appropriate loss coefficients for the variable orifices in each refueling region. Flow distributions following reactor trip and a reduction in coolant pressure and flow are determined assuming that the orifice coefficients remain constant. Iterative techniques are used to determine the distribution of coolant flow as a function of time during the transient. Results are presented for the evaluation of the transient for the Fort St. Vrain reactor following depressurization and cooling with two circulators operating at 8000 rpm.

    Full Text Available We analyze the surface water flow of Rio Grande between El Paso–Ciudad Juarez and Fort Quitman and estimate the structural changes occurred during 1923–2005. The study is based on a set of econometric equations to examine trends and turning points in data of time series. We find that water flow registered two important structural changes estimated in 1950 and 1972. There was a reduction in the water flow after the first structural change that is linked to the 1944 Treaty; whilethe second structural change is associated toincreases of the water flowthat seem to respond to the observation of the American flower and fauna law. In conclusion, the lower Rio Grande located between Ciudad–Juarez and Fort Quitman has received a minorwater flow from 1950.

  16. Alternative method for full flow stroke testing of safety injection tank check valves at Fort Calhoun Nuclear Station

  19. Paleomagnetism, U-Pb geochronology, and geochemistry of Marathon dykes, Superior Province, and comparison with the Fort Frances swarm

    International Nuclear Information System (INIS)

    We report the first detailed study of the paleomagnetism, U - Pb geochronology and major element geochemistry of Paleoproterozoic north-trending Marathon dykes north of Lake Superior. The paleomagnetic and geochemical results demonstrate that Marathon dykes can be divided into two subsets, one of normal magnetic polarity, the other of reverse polarity. Normal and reverse Marathon paleomagnetic poles, at 43oN, 196oE (dm = 9o, dp = 7o, number of dykes N = 16) and 51oN, 175oE (dm = 9o, dp = 6o, N 12), respectively, are statistically distinct and may indicate different ages of normal and reverse dyke emplacement. A U-Pb baddeleyite age of 2121-7+14 Ma has been obtained at a normally magnetized Marathon paleomagnetic site. The reversely magnetized Marathon dykes are undated, but have a paleopole rather close to that of the reversely magnetized 2076-4+5 Ma Fort Frances dykes and major element geochemical signatures as portrayed on Jensen plots that are identical to those of the Fort Frances swarm. Therefore, reverse Marathon and Fort Frances dykes could define a giant radiating dyke swarm focused south of Lake Superior, supporting models that associate these dykes with Paleoproterozoic rifting along the southern margin of the Superior Province. The Marathon and Fort Frances paleopoles continue a northwesterly trend in southern Superior Province paleopoles, which has recently been defined by results for 2216-4+8 Ma Senneterre dykes and 2167 ± 2 Ma Biscotasing dykes. This trend contrasts with previous widely used polar wander paths for the same period that young in the opposite direction and illustrates the importance of collaborative studies of paleomagnetism and U - Pb geochronology.

  20. Establishment of ambient air quality trends using historical monitoring data from Edmonton and Fort McKay, Alberta

    International Nuclear Information System (INIS)

    Ambient air trends were assessed using data collected over an 8 year period from monitoring stations in Edmonton and Fort McKay, Alberta. In particular, the study evaluated the short term trends in the concentration of carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM2.5) in Edmonton, as well as the NO2, O3, PM2.5, and total hydrocarbons in Fort McKay. In order to evaluate the ambient air trends, this study examined the changes in concentrations of these pollutants between the 50 - 90 percentiles of concentration distributions for a calendar year. These statistics were assumed to be linear over the period of study and fitted using simple linear regression. Hypothesis tests were performed to determine if the slopes of the best-fit lines were greater or less than zero. There was no indication of a statistically significant short-term trend for NO2 and O3 for the city of Edmonton. However, statistically pronounced decreasing trends were noted for CO and PM2.5. There was no indication of statistically significant trend for any of the pollutants examined at Fort McKay over the study period. It was cautioned that since the period of study over which trends were examined was short, the changes or lack of changes observed do not necessarily indicate long term trends. However, the results suggest that air quality has remained unchanged during the last 6 to 8 years, despite increased economic development in Edmonton and continued oil sands development in Fort McKay

  1. ORNL's NRC-sponsored HTGR safety and licensing analysis activities for Fort St. Vrain and advanced reactors

    International Nuclear Information System (INIS)

    The ORNL safety analysis program for the HTGR was established in 1974 to provide technical assistance to the USNRC on licensing questions for both Fort St. Vrain and advanced plant concepts. The emphasis has been on development of major component and system dynamic simulation codes, and use of these codes to analyze specific licensing-related scenarios. The program has also emphasized code verification, using Fort St. Vrain data where applicable, and comparing results with industry-generated codes. By the use of model and parameter adjustment routines, safety-significant uncertainties have been identified. A major part of the analysis work has been done for the Fort St. Vrain HTGR, and has included analyses of FSAR accident scenario re-evaluations, the core block oscillation problem, core support thermal stress questions, technical specification upgrade review, and TMI action plan applicability studies. The large, 2240-MW(t) cogeneration lead plant design was analyzed in a multi-laboratory cooperative effort to estimate fission product source terms from postulated severe accidents. (author)

  2. Developmental assessment of the Fort St. Vrain version of the composite HTGR analysis program (CHAP-2)

    International Nuclear Information System (INIS)

    The Composite HTGR Analysis Program (CHAP) consists of a model-independent systems analysis mainframe named LASAN and model-dependent linked code modules, each representing a component, subsystem, or phenomenon of an HTGR plant. The Fort St. Vrain version (CHAP-2) includes 21 coded modules that model the neutron kinetics and thermal response of the core; the thermal-hydraulics of the reactor primary coolant system, secondary steam supply system, and balance-of-plant; the actions of the control system and plant protection system; the response of the reactor building; and the relative hazard resulting from fuel particle failure. FSV steady-state and transient plant data are being used to partially verify the component modeling and dynamic simulation techniques used to predict plant response to postulated accident sequences. Results of these preliminary validation efforts are presented showing good agreement between code output and plant data for the portions of the code that have been tested. Plans for further development and assessment as well as application of the validated code are discussed. (author)

    Fort Munro Formation represents the products of the Upper Cretaceous (Maastrichtian) in the middle and lower Indus basins. The formation is exposed in the Rakhi Nala (Sulaiman Range), Bara Nala (Lakhi Range) and Naka Pabni (Southern Pab Range) areas. Major and trace elemental geochemistry and petrographic studies of the formation have been carried out to understand the facies trends in the middle and lower Indus basins. A high amount of acid-insoluble fraction, Ca/Mg and Mg vs. Ca/Sr ratio reveal that the formation was deposited in a shallow marine regressive environment. High amounts of clastic reflect abundant influx of terrigenous materials from the east (Indian craton) and west (Bibai volcanic). High Sr content indicates that aragonite was the precursor mineral, which was transformed into stable low-Mg calcite during diagenesis. Enrichment of Cu and Zn contents in the samples of the formation implies the influence of volcanic activity and that they were incorporated into the calcite lattice in the late phase.

    This report presents the results of an energy evaluation of the Central Food Preparation System (CFPS) and three dining halls at Fort Lee, Virginia. As far as cooking was concerned, there were energy savings in cooking large batches of food with large equipment at CFPS vs. cooking small batches of food with small equipment at the individual dining halls. However, due to the extra steps required for freezing, storing, and reheating of the CFPF prepared entrees, there was an additional energy expenditure as compared to foods freshly prepared and served in dining halls. Concerning the preparation of salads, gelatin desserts, and slicing of cold-cut meats in the Ingredient Preparation Facility (IPF), there was a net energy savings in using IPF-prepared foods because of no cook-freeze system involved. This report also presents data on comparisons of electricity vs. gas cooking and large batches vs. small batches. Considering different energy costs, electricity is ranked as the major energy cost, and the cost of heating water is second.

  5. Characterization plan for Fort St. Vrain and Peach Bottom graphite fuels

    International Nuclear Information System (INIS)

    Part of Fort St. Vrain (FSV) and most of the Peach Bottom (PB) reactor spent fuels are currently stored at INEL and may remain in storage for many years before disposal. Three disposal pathways have been proposed: intact disposal, fuels partially disassembled and the high-level waste fraction conditioned prior to disposal, and fuels completed disassembled and conditioned prior to disposal. Many options exist within each of these pathways. PNL evaluated the literature and other reference to develop a fuels characterization plan for these fuels. This plan provides guidance for the characteristics of the fuel which will be needed to pursue any of the storage or disposal pathways. It also provides a suggested fuels monitoring program for the current storage facilities. This report recommends a minimum of 7 fuel elements be characterized: PB Core 1 fuel: one Type II nonfailed element, one Type II failed element, and one Type III nonfailed element; PB Core 2 fuel: two Type II nonfailed fuel elements; and FSV fuel: at least two fuel blocks from regions of high temperature and fluence and long in-reactor performance (preferably at reactor end-of- life). Selection of PB fuel elements should focus on these between radial core position 8 and 14 and on compacts between compact numbers 10 and 20. Selection of FSV fuel elements should focus on these from Fuel Zones II and III, located in Core Layers 6, 7, and possibly 8

  6. Reactivation of the Shock-Tunnel Facility at Fort Cronkhite. Final report

    International Nuclear Information System (INIS)

    This final report describes the results of work undertaken to reactivate the Shock Tunnel Facility at Battery Townsley, Fort Cronkhite, Marin County, California. The facility has been reactivated and can not be utilized for blast testing. The major emphasis will be testing of concepts pertaining to programs of interest to the Federal Emergency Management Agency (FEMA) and in particular to civil defense oriented research. However, a wide variety of testing requirements can be accommodated. For example, past programs at the facility have included: tests of debris from trees subjected to blast for Bell Telephone Laboratories; tests of the response of aluminum hull panels to blast loading and of the response of a model surface effects ship for the Naval Ship Research and Development center, and tests of the response of a radome prototype to blast loading conducted for ANCOM (the radome manufacturer). The Shock Tunnel Facility is located in a former coastal defense 16-inch gun emplacement constructed by the US Army beginning in 1938. It was converted in 1967 to serve as a facility for full-scale testing of the loading and response of structural elements and civil defense equipment. It remained in operation until November 1976 when Battery Townsley was turned over to the National Park Service. Work under the present purchase order consisted of the following major tasks: (I) cleanup and secure the facility, (II) reactivate the shock tunnel, and (III) design permanent facility improvements

    The Dallas-Fort Worth (DFW) urban radar network consists of a combination of high resolution X band radars and a standard National Weather Service (NWS) Next-Generation Radar (NEXRAD) system operating at S band frequency. High spatiotemporal-resolution quantitative precipitation estimation (QPE) is one of the important applications of such a network. This paper presents a real-time QPE system developed by the Collaborative Adaptive Sensing of the Atmosphere (CASA) Engineering Research Center for the DFW urban region using both the high resolution X band radar network and the NWS S band radar observations. The specific dual-polarization radar rainfall algorithms at different frequencies (i.e., S- and X-band) and the fusion methodology combining observations at different temporal resolution are described. Radar and rain gauge observations from four rainfall events in 2013 that are characterized by different meteorological phenomena are used to compare the rainfall estimation products of the CASA DFW QPE system to conventional radar products from the national radar network provided by NWS. This high-resolution QPE system is used for urban flash flood mitigations when coupled with hydrological models.

    Limited visibility is the single most critical factor affecting the safety and capacity of worldwide aviation operations. Synthetic Vision Systems (SVS) technology can solve this visibility problem with a visibility solution. These displays employ computer-generated terrain imagery to present 3D, perspective out-the-window scenes with sufficient information and realism to enable operations equivalent to those of a bright, clear day, regardless of weather conditions. To introduce SVS display technology into as many existing aircraft as possible, a retrofit approach was defined that employs existing HDD display capabilities for glass cockpits and HUD capabilities for the other aircraft. This retrofit approach was evaluated for typical nighttime airline operations at a major international airport. Overall, 6 evaluation pilots performed 75 research approaches, accumulating 18 hours flight time evaluating SVS display concepts that used the NASA LaRC's Boeing B-757-200 aircraft at Dallas/Fort Worth International Airport. Results from this flight test establish the SVS retrofit concept, regardless of display size, as viable for tested conditions. Future assessments need to extend evaluation of the approach to operations in an appropriate, terrain-challenged environment with daytime test conditions.

  10. Response for flooding and effort of plant restart at Fort Calhoun NPP

    International Nuclear Information System (INIS)

    Fort Calhoun NPP(FCNPP) experienced flood due to the elevation of water level of Missouri river from June to August, 2011. FCNPP took various responses including constructing the berm around the important facilities, and could maintain the safety of the reactor with difficulty. The response of FCNPP, which includes both good and bad aspects, will help us in examining the response to flooding at Japanese nuclear plants. In response to the occurrence of the fire of safety related breaker at FCNPP, June 2011, NRC entered the oversight for FCNPP based on the Inspection Manual Chapter-0350 and issued the Confirmatory Action Letter (CAL) with the check list to Omaha Public Power District (OPPD), owner of FCNPP. Check list described the items which OPPD should solve before the restart of FCNPP. Although many efforts need to be done by OPPD to solve the check list, there is transparency about the condition of the plant restart. In Japan all the plants except Ohi 3,4 have continued to shut down after Fukushima accident due to the lack of the rule for restarting of the plant after the occurrence of the safety problem. We should study the plant restart system of NRC. (author)

  11. The analysis and evaluation of recent operational experience from the Fort St. Vrain HTGR

    International Nuclear Information System (INIS)

    The U.S. Nuclear Regulatory Commission's Office of Analysis and Evaluation of Operational Data has established an extensive program for screening, analyzing, and evaluating the operational experience data from all commercial nuclear power plants in the United States. This program is designed to provide feedback from field experience with actual operating events to the NRC's continuing efforts to assure the public's health and safety. Oak Ridge National Laboratory provides technical assistance to AEOD to evaluate the operating experience for Fort St. Vrain. Water ingress events continued to be a frequent problem caused most often by electrical/control system upsets. The most recent such event was in June 1983, when the circulator upset led to a moisture ingress large enough to cause icing of chillers in the helium purification train but apparently not large enough to be detected as a problem from available analytical monitors. As a result, the reactor was exposed to several hours of undiagnosed levels of ''high'' moisture, loss of purified helium flow to control rod mechanisms and finally a reactor scram in which 6 of 37 control rod pairs failed to insert automatically. Evidence has also been uncovered that high moisture has caused the transport of volatile chlorides throughout the reactor resulting in corrosion of stainless steel control rod cables and possibly hold down bolts used on a helium circulator closure. Moisture has also caused severe leaching of B2O3 contaminant from the reserve shutdown materials, precluding the complete dumping of material during a surveillance test

    British Columbia Hydro and Power Authority (BC Hydro) and TransAlta Energy Corp. (TransAlta) have applied for a certificate of approval for the proposed construction of the Fort Nelson Energy Generation Project (FNEGP). The project will involve the design, construction, operation, dismantling and abandonment of a 45 MW combustion turbine power plant about 20 km south of Fort Nelson near Westcoast Energy`s gas plant. The proposed project will provide base load power to the town of Fort Nelson which now receives its electricity from Rainbow Lake, Alberta. Once FNEGP is operational, the standby diesel power plant in Fort Nelson will be decommissioned. The main issues raised during the review of the project were the potential impacts on air quality, water supply and waste management. It was determined that it is unlikely that the project will result in any significant negative impacts on terrestrial ecology, wildlife or aquatic life. The project would likely provide greenhouse gas offsets, since it would replace electricity from the Alberta Power Pool which is derived mostly from coal-fired thermal sources. Wastewater discharges from the project will be accommodated by Westcoast Energy`s wastewater treatment system. The proposed disposal of solid wastes and handling of special wastes was also found to be acceptable. Although there will be few opportunities for spills, the proponents have agreed to prepare an emergency response plan for use in the event of reportable spills. The socio-economic implications of the project are mostly positive with any negative impacts being minor in nature. Based on its review of the application the Project Committee recommended issuance of an approval certificate.

    The Fort Cobb Reservoir Watershed (FCRW) (830 km2) is a watershed within the HELP Washita Basin, located in Caddo and Washita Counties, OK. It is also a benchmark watershed under USDA's Conservation Effects Assessment Project, a national project to quantify environmental effects of USDA and other conservation programs. Population in south-western Oklahoma, in which FCRW is located, is sparse and decreasing. Agricultural focuses on commodity production (beef, wheat, and row crops) with high costs and low margins. Surface and groundwater resources supply public, domestic, and irrigation water. Fort Cobb Reservoir and contributing stream segments are listed on the Oklahoma 303(d) list as not meeting water quality standards based on sedimentation, trophic level of the lake associated with phosphorus loads, and nitrogen in some stream segments in some seasons. Preliminary results from a rapid geomorphic assessment results indicated that unstable stream channels dominate the stream networks and make a significant but unknown contribution to suspended-sediment loadings. Impairment of the lake for municipal water supply, recreation, and fish and wildlife are important factors in local economies. The Thika River Watershed (TRW) (867 km2) is located in central Kenya. Population in TRW is high and increasing, which has led to a poor land-population ratio with population densities ranging from 250 people/km2 to over 500 people/km2. The poor land-population ratio has resulted in land sub-division, fragmentation, over- cultivation, overgrazing, and deforestation which have serious implications on soil erosion, which poses a threat to both agricultural production and downstream reservoirs. Agricultural focuses mainly on subsistence and some cash crops (dairy cattle, corn, beans, coffee, floriculture and pineapple) farming. Surface and groundwater resources supply domestic, public, and hydroelectric power generation water. Thika River supplies 80% of the water for the city of

    The information presented in this report was collected during limited site investigation activities conducted in the vicinity of Landfills 1 and 4 at Fort Lewis. The purpose of this work was to provide a means of detecting and evaluating the impacts of these inactive landfills on ground-water quality and adjacent lands. This effort included the design and construction of ground-water monitoring systems for compliance with applicable federal and state regulations governing Resource Conservation and Recovery Act (RCRA)-type landfills. Ground-water samples were collected from both existing (1981 and 1984) wells and the newly installed (1988) wells. The analytical results from the water samples indicate that the ground water in and around Landfill 1 contains limited contamination. Contaminants may include volatile organic compounds and nitrate. The primary concern in the area around Landfill 1 was the determination that ground water from two wells may contain cis-1,2-dichloroethylene and 1,1,1-trichloroethylene above drinking water standards. Nitrate levels in the downgradient wells were greater than those in upgradient wells and exceeded drinking water standards in some of the less-representative samples. Analyses of ground-water samples from wells in and around Landfill 4 indicate several contaminants may be present. These include volatile organic compounds (principally cis-1,2-dichloroethylene and 1,1,1-trichloroethylene), coliform, oil and grease, and perhaps some metals (iron and magnesium). The primary concern in the area around Landfill 4 was the determination that ground water from five wells contained cis-1,2-dichloroethylene and 1,1,1-trichloroethylene above drinking water standards. The source of contaminants beneath either landfill cannot yet be identified. Insufficient data exist to disprove or confirm either landfill as possible contributors. 19 refs., 32 figs., 17 tabs.

  15. Phytosociological attributes of plant biodiversity of the Fort Ranikot and adjoining area (Kirthar range)

    International Nuclear Information System (INIS)

    The plant biodiversity, floristic composition and phytosociological attributes of the vascular plants of Fort Ranikot were analyzed. A total of 107 taxa were collected belonging to 41 families and 78 genera. The largest family was Poaceae containing 9 taxa, while the other major families were Papilionaceae with 6 species; Asclepiadaceae, Mimosaceae, and Solanaceae comprising of 5 species each respectively. Majority of the taxa are common throughout the study area, however, 6 species Viz. Aristolochia bracteolata, Physorrhynchus brahuicus, Plantago ciliata, Polygala erioptera, Salvadora persica and Viola stocksii were found to be very rare. The flora is dominated by Chamaephyte, followed by Therophytes, Phanerophytes, Hemicryptophytes and climbers. The aim of the present study is to provide comprehensive inventory of the study area along with its phytosociology and ecological parameters. Collectively on the basis of important value index six plants communities were recognized from different sites of the study area. The study area was categorized into six ecological sites on the basis of microclimatic conditions and topography. For comparison in these sites similarity index, beta diversity, diversity index, species evenness and maturity index was also calculated. The soil texture classes varied from loam to sandy loam and slit loam with pH of 7.78-8.24, electrical conductivity varied from 687-827 EC micro S/cm, Total dissolved salts varied from 0.36-0.71 mg-1, CaCO/sub 3/ varied from 3.48-4.21% and organic matter varied from 0.39-1.24%. Present study predict that there are certain edaphic factors, altitudinal variation, soil texture and amount of organic matter which are responsible for variation in vegetation. (author)

    The aim of our study was to evaluate orbital volume modification with LeFort III midface distraction in patients with craniosynostosis and its influence on eyeball volume and axial diameter modification. Orbital volume was assessed by the semiautomatic segmentation method based on deformable surface models and on 3-dimensional (3D) interaction with haptics. The eyeball volumes and diameters were automatically calculated after manual segmentation of computed tomographic scans with 3D slicer software. The mean, minimal, and maximal differences as well as the standard deviation and intraclass correlation coefficient (ICC) for intraobserver and interobserver measurements reliability were calculated. The Wilcoxon signed rank test was used to compare measured values before and after surgery. P < 0.05 was considered statistically significant. Intraobserver and interobserver ICC for haptic-aided semiautomatic orbital volume measurements were 0.98 and 0.99, respectively. The intraobserver and interobserver ICC values for manual segmentation of the eyeball volume were 0.87 and 0.86, respectively. The orbital volume increased significantly after surgery: 30.32% (mean, 5.96  mL) for the left orbit and 31.04% (mean, 6.31  mL) for the right orbit. The mean increase in eyeball volume was 12.3%. The mean increases in the eyeball axial dimensions were 7.3%, 9.3%, and 4.4% for the X-, Y-, and Z-axes, respectively. The Wilcoxon signed rank test showed that preoperative and postoperative eyeball volumes, as well as the diameters along the X- and Y-axes, were statistically significant. Midface distraction in patients with syndromic craniostenosis results in a significant increase (P < 0.05) in the orbit and eyeball volumes. The 2 methods (haptic-aided semiautomatic segmentation and manual 3D slicer segmentation) are reproducible techniques for orbit and eyeball volume measurements. PMID:26086925

    Buildings 7740 and 7741 are a part of a former nuclear weapon`s storage and maintenance facility located in the southeastern portion of Fort Campbell, Kentucky. This underground tunnel complex was originally used as a classified storage area beginning in 1949 and continuing until 1969. Staff from the Pacific Northwest National Laboratory recently completed a detailed Relative Risk Site Evaluation of the facility. This evaluation included (1) obtaining engineering drawings of the facility and associated structures, (2) conducting detailed radiological surveys, (3) air sampling, (4) sampling drainage systems, and (5) sampling the underground wastewater storage tank. Ten samples were submitted for laboratory analysis of radionuclides and priority pollutant metals, and two samples submitted for analysis of volatile organic compounds. No volatile organic contaminants were detected using field instruments or laboratory analyses. However, several radionuclides and metals were detected in water and/or soil/sediment samples collected from this facility. Of the radionuclides detected, only {sup 226}Ra may have come from facility operations; however, its concentration is at least one order of magnitude below the relative-risk comparison value. Several metals (arsenic, beryllium, cadmium, copper, mercury, lead, and antimony) were found to exceed the relative-risk comparison values for water, while only arsenic, cadmium, and lead were found to exceed the relative risk comparison values for soil. Of these constituents, it is believed that only arsenic, beryllium, mercury, and lead may have come from facility operations. Other significant hazards posed by the tunnel complex include radon exposure and potentially low oxygen concentrations (<19.5% in atmosphere) if the tunnel complex is not allowed to vent to the outside air. Asbestos-wrapped pipes, lead-based paint, rat poison, and possibly a selenium rectifier are also present within the tunnel complex.

    Sustainable use of military training lands requires understanding and prediction of the effects of military vehicles on vegetation. We examined the initial impacts of an 8-wheeled, light armored vehicle (LAV) on grassland vegetation at Fort Lewis, Washington. The LAV drove replicate spiral paths at two starting velocities, 10.3 and 5.1 m s(-1). The disturbed width (width of ground impacted by the tires) increased as turning radius decreased, but was unaffected by vehicle velocity. An inverse-exponential model predicted disturbed width (r(2)=0.68) at all turning radii for both velocities combined. In low-velocity spirals, and for straight tracking (turning radius>40 m) and moderate turns (radius 20-40 m) in high-velocity spirals, all vegetation damage was imprint (plants flattened by wheels). During sharp (radius moderate turns>sharp turns in high-velocity spirals. In low-velocity spirals, post-tracking cover of several plant growth forms (non-native species, perennial species, sod-forming grasses) was similar to pre-tracking cover, but in high-velocity spirals, post-tracking cover of these growth forms decreased in the order straight > or =moderate=sharp. Cover of native species and forbs decreased more in high- than in low-velocity spirals, but was unaffected by curvature. Pre- and post-tracking cover of annual species, bunchgrasses, and shrubs was < or =3%. The most severe vegetation damage caused by operation of wheeled LAVs on grasslands is associated with sharp, high-velocity turns. PMID:16549228

    Some species are rare because they are restricted to certain habitats and/or have small population sizes. Monterey spineflower, a federally listed threatened annual plant, is found in open sandy regions of the California coast, in chaparral vegetation around the Monterey Bay. A model based on previous research suggests that the Monterey spineflower population at Fort Ord Natural Reserve should be rapidly increasing, but it is not. This suggests that the model may be using data that overestimates the percentage of spineflower seeds that successfully germinate. I tested three hypotheses to determine the cause of the difference in population sizes between the predicted model and the field results. First, I predicted that the spineflower seeds are blown by the wind into shrubs such as manzanita, and are unable to germinate due to the lack of a suitable environment. I tested this in two ways. A field experiment showed that seeds are easily blow by wind. Next, I took soil cores and found spineflower seeds within the manzanita shrubs. Secondly, I predicted that the germination rate used by the model (90%) was too high. However, my germination experiments did not support this hypothesis because 91% of new seeds successfully germinated. Lastly, I predicted that the newer seeds are more viable than older seeds and therefore have a higher chance of successfully germinating. After germinating seeds in a controlled environment I observed that the seeds from 2014 had a higher number of successfully germinated seeds compared to the number of successfully germinated seeds from 1995 (91% vs 33%). I conclude that the loss of seeds due to wind decreases germination expectancies and older seeds are less viable than new seeds. Therefore, Monterey spineflower is a rare plant because environmental barriers hinder seeds from dispersing to a suitable habitat and successfully germinating while seeds lose viability as they age.

  20. Conceptual design report for handling Fort St. Vrain fuel element components

    International Nuclear Information System (INIS)

    This report presents conceptual designs for containment of high-level wastes (HLW) and low-level wastes (LLW) that will result from disassembly of fuel elements from the High Temperature Gas-Cooled Reactor at the Fort St. Vrain nuclear power plant in Platteville, Colorado. Hexagonal fuel elements will enter the disassembly area as a HLW and exit as either as HLW or LLW. The HLW will consist of spent fuel compacts that have been removed from the hexagonal graphite block. Graphite dust and graphite particles produced during the disassembly process will also be routed to the container that will hold the HLW spent fuel compacts. The LLW will consist of the emptied graphite block. Three alternatives have been introduced for interim storage of the HLW containers after the spent fuel has been loaded. The three alternatives are: (a) store containers where fuel elements are currently being stored, (b) construct a new dry storage facility, and (c) employ Multi-Purpose Canisters (currently in conceptual design stage). Containment of the LLW graphite block will depend on several factors: (a) LLW classification, (b) radiation levels, and (c) volume-reducing technique (if used). Packaging may range from cardboard boxes for incinerable wastes to 55-ton cask inserts for remote-handled wastes. Before final designs for the containment of the HLW and LLW can be developed, several issues need to be addressed: (a) packing factor for fuel compacts in HLW container, (b) storage/disposal of loaded HLW containers, (c) characterization of the emptied graphite blocks, and (d) which technique for volume-reduction purposes (if any) will be used

  1. Extracting the social relevance of artefact distribution in Roman military forts

    2005-04-01

    Full Text Available 'Engendering Roman Spaces' is a research project concerned with using artefact assemblage analyses to better understand spatial and gender relationships in the early Roman Empire and to produce more engendered perspectives of Roman society. This paper discusses the methodology and analyses being used in this project to investigate social behaviour within Roman military forts and fortresses of the 1st and 2nd centuries CE through analyses of the spatial distribution of artefacts at these sites. The processes involved include digitising previously published maps and artefact catalogues from Roman military sites to create searchable databases and GIS maps. They also include the classification of the artefacts according to a number of functional and gender-associated categories (e.g. combat equipment, male and female dress, toilet etc. so that the spatial distributions of the relevant activities can be plotted. This data is then used to interpret the spatial relationships of these activities and the people involved in them. The double legionary fortress of Vetera I, on the Lower Rhine, has been used to exemplify these processes. This fortress was excavated in the early 20th century and the artefacts were comprehensively published in 1995 (N. Hanel, Vetera I: Die Funde aus den römischen Lagern auf dem Fürstenberg bei Xanten. Rheinische Ausgrabungen 35, Rheinland-Verlag, Cologne and Dr Rudolf Halbert, Bonn, 1995. The paper includes descriptions of the methods and software employed in the digitisation of relevant material from these volumes, the formation of relational databases, and the importation of this data and of site maps into a GIS programme. To illustrate these processes and to present some of the results, the paper also includes a number of examples of the analyses carried out, together with interactive GIS maps of these analyses.

  2. Effectiveness of adenoplex forte with or without heparegene as radioprotective and curative agent for controlling radiation induced hepatic metabolic dysfunction

    International Nuclear Information System (INIS)

    The present work aims to evaluate the combined radioprotective and curative capacities of a known drug namely adenoplex forte [combination of adenosine tetraphosphate (ATP), co carboxylase, cyanocobalamin (Bn) and nicotinamide (vitamin P.P)] in dependency or in combination with heparegen [thiazolidine 4 -carboxylic acid] on liver metabolic processes of rats irradiated at 5 Gy. Therefore, the levels of plasma total lipids, triglycerides, total cholesterol, HDL-cholesterol and LDL-cholesterol were estimated as indicative parameters for lipid metabolism. Estimations of plasma glucose, pyruvate and lactate levels as well as liver glycogen content were employed as a useful means for testing the carbohydrate metabolism. The tested parameters were undertaken on 3, 7, 14, 21 and 30 days post-radiation exposure of rats to 5 Gy. Data of the present study revealed that exposure of rats to gamma irradiation at a dose level of 5 Gy was associated with disturbances in liver metabolic functions as reflected by alterations observed in all the tested parameters of both lipid and carbohydrate metabolism up to 30 days post-irradiation. The data further indicated that appropriate use of the selected drug adenoplex forte either independently or in combination with heparegen can preferentially modify liver metabolic disturbances induced by radiation exposure, which creates a therapeutic advantage in radiation therapy. In conclusion, this study suggest the potential use of adenoplex forte (with dose of 290 mg/kg) in combination with heparegen (with dose of 2 mg/kg) in patients receiving radiotherapy and suffering disturbed liver metabolic function mainly in carbohydrate and lipid metabolism

    The unicystic ameloblastoma (UA) presents the clinical and radiographic characteristics of a maxillary cyst, making early diagnosis difficult. A 30-year-old man had an extensive, asymptomatic lesion in the right maxillary sinus. Radiographic examinations demonstrated a retained tooth in association with a lesion. Histopathologic examination revealed the presence of UA with intraluminal and mural infiltration and a follicular pattern. Le Fort I access was chosen for enucleation of the lesion and curettage of the site, which were followed by cryotherapy. The treatment provided adequate intraoperative visibility, enabled the preservation of the surrounding bone, and eliminated postoperative complications. Follow-up over 5 years demonstrated no recurrence. PMID:27148651

    The Fort Smith quadrangle in western Arkansas and eastern Oklahoma overlies thick Paleozoic sediments of the Arkoma Basin. These Paleozoics dominate surface exposure except where covered by Quaternary Alluvial materials. Examination of available literature shows no known uranium deposits (or occurrences) within the quadrangle. Seventy-five groups of uranium samples were defined as anomalies and are discussed briefly. None were considered significant, and most appeared to be of cultural origin.

    Tooth enamel of nine Middle Miocene mammalian herbivores from Fort Ternan, Kenya, was analyzed for delta 13C and delta 18O. The delta 18O values of the tooth enamel compared with pedogenic and diagenetic carbonate confirm the use of stable isotope analysis of fossil tooth enamel as a paleoenvironmental indicator. Furthermore, the delta 18O of tooth enamel indicates differences in water sources between some of the mammals. The delta 13C values of tooth enamel ranged from -8.6(-)-13.0/1000 which is compatible with a pure C3 diet, though the possibility of a small C4 fraction in the diet of a few of the specimens sampled is not precluded. The carbon isotopic data do not support environmental reconstructions of a Serengeti-typed wooded grassland with a significant proportion of C4 grasses. This study does not preclude the presence of C3 grasses at Fort Ternan; it is possible that C3 grasses could have had a wider geographic range if atmospheric CO2 levels were higher than the present values.

    The federal government is the largest single energy consumer in the United States cost valued at nearly $10 billion annually. The US Department of Energy`s (DOE) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the federal sector. One such effort, the New Technology Demonstration Program (NTDP), seeks to evaluate new energy-saving US technologies and secure their more timely adoption by the US government. Pacific Northwest Laboratory (PNL) is one of four DOE laboratories that participate in the New Technologies Demonstration Program, providing technical expertise and equipment to evaluate new, energy-saving technologies being studied under that program. This interim report provides the results of a field evaluation that PNL conducted for DOE/FEMP and the US Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP) to examine the performance of a candidate energy-saving technology-a hot water heater conversion system to convert electrically heated hot water tanks to natural gas fuel. The unit was installed at a single residence at Fort Stewart, a US Army base in Georgia, and the performance was monitored under the NTDP. Participating in this effort under a Cooperative Research and Development Agreement (CRADA) were Gas Fired Products, developers of the technology; the Public Service Company of North Carolina; Atlanta Gas Light Company; the Army Corps of Engineers; Fort Stewart; and Pacific Northwest Laboratory.

    Land use activities can have a major impact on the temporal trendsandspatialpatternsofregionalland-atmosphereexchange of carbon. Federal lands generally have substantially different land management strategies from surrounding areas, and the carbon consequences have rarely been quantified and assessed. Using the Fort Benning Installation as a case study, we used the General Ensemble biogeochemical Modeling System (GEMS) to simulate and compare ecosystem carbon sequestration between the U.S. Army's Fort Benning and surrounding areas from 1992 to 2050. Our results indicate that the military installation sequestered more carbon than surrounding areas from 1992 to 2007 (76.7 vs 18.5 g C m-2 yr-1), and is projected to continue sequestering more carbon from 2008 to 2050 (75.7 vs 25.6 g C m-2 yr-1), mostly because of the proactive management approaches adopted on military training lands. Our results suggest that federal lands might play a positive and important role in sequestering and conserving atmospheric carbon because some anthropogenic disturbances (e.g., urbanization, forest harvesting, and agriculture) can be minimized or prevented on federal lands

    This report presents an intercomparison of three groundwater flow monitoring technologies at a trichloroethylene (TCE) groundwater plume at Operational Unit 1 (OU 1) adjacent to the former Fritzsche Army Airfield at the former Fort Ord Army Base, located on Monterey Bay in northern Monterey County, California. Soil and groundwater at this site became contaminated by fuels and solvents that were burned on a portion of OU 1 called the Fire Drill Area (FDA) as part of firefighter training from 1962 and 1985. Cont Contamination is believed to be restricted to the unconfined A-aquifer, where water is reached at a depth of approximately 60 to 80 feet below the ground surface; the aquifer is from 15 to 20 feet in thickness, and is bounded below by a dense clay layer, the Salinas Valley Aquitard. Soil excavation and bioremediation were initiated at the site of fire training activities in the late 1980s. Since that time a pump-and-treat operation has been operated close to the original area of contamination, and this system has been largely successful at reducing groundwater contamination in this source area. However, a trichloroethylene (TCE) groundwater plume extends approximately 3000 ft (900 m) to the northwest away from the FDA. In this report, we have augmented flow monitoring equipment permanently installed in an earlier project (Oldenburg et al., 2002) with two additional flow monitoring devices that could be deployed in existing monitoring wells, in an effort to better understand their performance in a nearly ideal, homogeneous sand aquifer, that we expected would exhibit laminar groundwater flow owing to the site's relatively simple hydrogeology. The three flow monitoring tools were the Hydrotechnics{reg_sign} In In-Situ Permeable Flow Sensor (ISPFS), the RAS Integrated Subsurface Evaluation Hydrophysical Logging tool (HPL), and the Lawrence Livermore National Laboratory Scanning Colloidal Borescope Flow Meter (SCBFM). All three devices produce groundwater

  11. Effect of Surface Traffic Count on Taxi Time at Dallas-Fort Worth (DFW) International Airport

    Kistler, Matthew Stephen; Gupta, Gautam

    2008-01-01

    As the amount of air traffic increases over the years, most airports simply do not have the means of expanding to handle the intensified traffic on the surface that will ensue. Precise surveillance equipment and automation concepts, as well as advanced surface traffic algorithms are being developed to improve airport efficiency. These surface algorithms require inputs unique to each airport to ensure maximum efficiency, and minimal taxi delay. This study analyzes surface traffic at Dallas-Fort Worth International Airport (DFW) to determine the effect of the number of aircraft on the surface and the amount of stop and go situations they experience to the amount of additional taxi time encountered. If the surface capacity of an airport is known, minimal delay can be accomplished by limiting the number of taxiing aircraft to that capacity. This concept is related to highways, where traffic flow drastically decreases as more cars occupy the road. An attempt to minimize this effect on highways is seen with the use of metering lights at freeway on-ramps. Since the surface traffic at airports is highly regulated, and aircraft are less mobile on the ground, limiting the surface count to a certain number can greatly reduce the amount of additional taxi time encountered, as well as reduce hazardous emissions. This study will also find the regions of an airport that encounter the most additional taxi time when the number of aircraft in that area is increased. This could help surface traffic algorithms avoid congesting that area, or re-route aircraft to different runways when that area reaches its capacity. The relationship between the amount of stop and go situations an aircraft encounters and their effect on the taxi time of that aircraft will also be investigated. This will help to determine the effect of holding an aircraft on the taxiway as opposed to re-routing it. The lesser of the two should be used when developing surface traffic algorithms to further minimize the

    An investigation was conducted at the Knox Street fire pits, Fort Bragg, North Carolina, to monitor the distribution of toluene, ethylbenzene, and xylene (TEX) in soil vapor, ground water, and ground-water/vapor to evaluate if total concentrations of TEX at the site are decreasing with time, and to quantify biodegradation rates of toluene in the unsaturated and saturated zones. Soil-vapor and ground-water samples were collected around the fire pits and ground-water/vapor samples were collected along the ground-water discharge zone, Beaver Creek, on a monthly basis from June 1994 through June 1995. Concentrations of TEX compounds in these samples were determined with a field gas chro- matograph. Laboratory experiments were performed on aquifer sediment samples to measure rates of toluene biodegradation by in situ micro- organisms. Based on field gas chromatographic analytical results, contamination levels of TEX compounds in both soil vapor and ground water appear to decrease downgradient of the fire-pit source area. During the 1-year study period, the observed temporal and spatial trends in soil vapor TEX concentrations appear to reflect differences in the distribution of TEX among solid, aqueous, and gaseous phases within fuel-contaminated soils in the unsaturated zone. Soil temperature and soil moisture are two important factors which influence the distribution of TEX com- pounds among the different phases. Because of the short period of data collection, it was not possible to distinguish between seasonal fluc- tuations in soil vapor TEX concentrations and an overall net decrease in TEX concentrations at the study site. No seasonal trend was observed in total TEX concentrations for ground- water samples collected at the study site. Although the analytical results could not be used to determine if ground-water TEX concen- trations decreased during the study at a specific location, the data were used to examine rate constants of toluene biodegradation.

    The Carolawn Company site, 4 kilometers west of Fort Lawn, South Carolina, is an abandoned waste storage and disposal facility on the United States Environmental Protection Agency's National Priorities List. Currently available data identify the presence of lead, benzene, and chlorinated aliphatic compounds in on-site and off-site groundwater. Contaminated groundwater was used for potable water by at least one household. Fishing Creek is a presumed groundwater discharge zone. Residences between the site and Fishing Creek are stated to be using a public water supply. Past sampling data of Fishing Creek have not indicated contamination. A Phase II Hydrogeologic Investigation is currently being performed. Public health considerations indicate the need for completion of site cleanup, monitoring of Fishing Creek for contamination, and abandonment of groundwater wells within the affected area (as per State regulations.)

    Geophysical methods such as seismic, gravity, magnetics, electric, and electromagnetics are capable of identifying subsurface features but each has a different spatial resolution. Although, each of these methods are stand-alone tools and have produced wonderful and reliable results for decades to solve geological problems, integrating geophysical results from these different methods with geological and geospatial data, adds an extra dimension towards solving geological problems. Integration techniques also involve comparing and contrasting the structural and tectonic evolution of geological features from different tectonic and geographic provinces. I employed 3D and 2D seismic data, passive seismic data, and gravity and magnetic data in three studies and integrated these results with geological, and geospatial data. Seismic processing, and interpretation, as well as filtering techniques applied to the potential filed data produced many insightful results. Integrated forward models played an important role in the interpretation process. The three chapters in this dissertation are stand-alone separate scientific papers. Each of these chapters used integrated geophysical methods to identify the subsurface features and tectonic evolution of the study areas. The study areas lie in the southeast Fort Worth Basin, Texas, Harney Basin, Oregon, and Snake River Plain, Idaho. The Fort Worth Basin is one of the most fully developed shale gas fields in North America. With the shallow Barnett Shale play in place, the Precambrian basement remains largely unknown in many places with limited published work on the basement structures underlying the Lower Paleozoic strata. In this research, I show how the basement structures relate to overlying Paleozoic reservoirs in the Barnett Shale and Ellenburger Group. I used high quality, wide-azimuth, 3D seismic data near the southeast fringe of the Fort Worth Basin. The seismic results were integrated with gravity, magnetic, well log, and

  20. Computer simulation of pulsed-neutron experiments performed on the Fort St. Vrain high-temperature gas-cooled reactor

    International Nuclear Information System (INIS)

    Computer simulations were used to determine the optimum source location, detector location, and pulse rate prior to performing pulsed-neutron experiments on the 330-MW Fort St. Vrain high-temperature gas-cooled reactor (HTGR). The simulation procedure involved calculation of the amplitudes, decay constants, and modal shapes of the first few kinetic modes in the general expansion of the time response of the neutron flux following each pulse. The kinetic modes were calculated by the eigenfunction expansion method in two-dimensional geometry assuming two energy groups and six delayed-neutron precursors. The major limitation in the calculation is the use of two-dimensional core models, i.e., the assumption of separation of variables. For most power reactors on which pulsed-neutron experiments might be performed, this limitation should not be serious

    During the upper Cambrian, a transgression inundated the Southern Oklahoma aulacogen enveloping a landscape that consisted of hills of Cambrian-aged rhyolite up to 350 m in height. Initial deposits on this topography--the Reagan Formation--consist of siliciclastics that were deposited as alluvium and succeeding tidally-influenced marine sandstones and shales. The siliciclastics grains are made up of local rhyolite, quartz and authigenic glauconite. The overlying Honeycreek Formation is defined by the addition of carbonated detritus in the form of tidally-influenced pelmatozoan grainstones. The passage from the Honeycreek to the overlying Fort Sill Formation of the Arbuckle Group is marked by the incoming of beds of lime mudstone and the gradual disappearance of grainstones and siliciclastics. The contact between the Fort Sill and the overlying thinly-bedded dark grey bioclastic limestones of the Signal Mountain Formation is one of the most distinctive horizons in the Arbuckle Group. The contact evidently marks a substantial change in depositional environment. In detail the contact is sharp and shows evidence of minor erosion, although no karsting has been detected. The authors suggest that the contact surface records a regression, perhaps associated with dolomitization and followed by some erosion. A regression is also indicated by the local occurrence of a laminated tidal flat unit with traces of evaporites that outcrops in the far west of the Slick Hills immediately below the formation contact. They suggest that the Signal Mountains as a transgressive unit, incorporating siliciclastics transported into the area during the regression. It has been suggested that the unconformity reflects localized tectonism associated with the evolution of the Southern Oklahoma aulacogen. On the other hand the surface may correlate with a craton--wide Sauxian' hiatus.

    International Nuclear Information System (INIS)

    The Alberta Energy and Utilities Board considered an application by Shell Canada Limited to construct and operate an oil sands bitumen upgrader on Shell's property adjoining the existing Scotford refinery in the County of Strathcona. The upgrader would process bitumen from Shell's proposed Muskeg River Mine, located 70 km north of Fort McMurray, and other feedstocks available in the area. The Board also considered an application for an amendment to the existing Scotford refinery approval, Industrial Development Permit 89-10, for the processing of 3.75 million cubic metres per year of sour conversion feedstock. Under a coordinated application process, Shell filed a joint Shell Scotford Upgrader application/Environmental Impact Assessment. Issues considered with respect to these applications were: technology selection, air/health, sulphur recovery, noise/traffic, and land use conflict. Shell stated that its Scotford refinery is the most energy efficient refinery in the Americas and that is has the highest liquid yield per unit volume of crude oil feedstock of any refinery in the world. The refinery's hydrocracking capacity would make it possible to use hydro-conversion technology for its upgrader which is environmentally advantageous. After examining all of the evidence pertaining to the applications, the Board found the projects to be in the public interest and is prepared to approve the Scotford Upgrader and Scotford Refinery modifications assuming that certain prescribed conditions are met

    The ATU/Fort Hood Solar Total Energy System will include a concentrating solar collector field of several acres. During periods of direct insolation, a heat-transfer fluid will be circulated through the collector field and thus heated to 500 to 600/sup 0/F. Some of the fluid will be circulated through a steam generator to drive a turbine-generator set; additional fluid will be stored in insulated tanks for use when solar energy is not available. The electrical output will satisfy a portion of the electrical load at Fort Hood's 87,000 Troop Housing Complex. Heat extracted from the turbine exhaust in the form of hot water will be used for space heating, absorption air conditioning, and domestic water heating at the 87,000 Complex. Storage tanks for the hot water are also included. The systems analysis and program support activities include studies of solar availability and energy requirements at Fort Hood, investigation of interfacing LSE-1 with existing energy systems at the 87,000 Complex, and preliminary studies of environmental, health, and safety considerations. An extensive survey of available concentrating solar collectors and modifications to a computerized system simulation model for LSE-1 use are also reported. Important program support activities are military liaison and information dissemination. The engineering test program reported involved completion of the Solar Engineering Test Module (SETM) and extensive performance testing of a single module of the linear-focusing collector.

In summarizing the various experiences, individual experiences have been placed under one of the following general categories: (1) experiences associated with fabrication, construction and startup management; (2) experiences associated with design details which have general applicability; and (3) experiences associated with design details which are unique to the gas-cooled reactor concept. The experiences associated with the first two general categories have some applicability outside of gas-cooled reactors, while experiences associated with the third general category are more specific to reactors with design features similar to those of the Fort St. Vrain plant. Under each general category the specific experiences at Fort St. Vrain are discussed in terms of a generic item such as ''inadequate capacity of equipment'' and references to the discussion of the specific experiences in the three phase reports are presented. The summary report therefore serves as a guide to the discussions of the specific experiences contained in the three accompanying phase reports

    This volume documents the preliminary design developed for the Solar Total Energy System to be installed at Fort Hood, Texas. Current system, subsystem, and component designs are described and additional studies which support selection among significant design alternatives are presented. Overall system requirements which form the system design basis are presented. These include program objectives; performance and output load requirements; industrial, statutory, and regulatory standards; and site interface requirements. Material in this section will continue to be issued separately in the Systems Requirements Document and maintained current through revision throughout future phases of the project. Overall system design and detailed subsystem design descriptions are provided. Consideration of operation and maintenance is reflected in discussion of each subsystem design as well as in an integrated overall discussion. Included are the solar collector subsystem; the thermal storage subsystem, the power conversion sybsystem (including electrical generation and distribution); the heating/cooling and domestic hot water subsystems; overall instrumentation and control; and the STES building and physical plant. The design of several subsystems has progressed beyond the preliminary stage; descriptions for such subsystems are therefore provided in more detail than others to provide complete documentation of the work performed. In some cases, preliminary design parameters require specific verificaton in the definitive design phase and are identified in the text. Subsystem descriptions will continue to be issued and revised separately to maintain accuracy during future phases of the project. (WHK)

  13. Fort Collins Science Center- Policy Analysis and Science Assistance Branch : Integrating social, behavioral, economic and biological sciences

    Science.gov (United States)

    2010-01-01

    The Fort Collins Science Center's Policy Analysis and Science Assistance (PASA) Branch is a team of approximately 22 scientists, technicians, and graduate student researchers. PASA provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and biological analyses in the context of human-natural resource interactions. Resource planners, managers, and policymakers in the U.S. Departments of the Interior (DOI) and Agriculture (USDA), State and local agencies, as well as international agencies use information from PASA studies to make informed natural resource management and policy decisions. PASA scientists' primary functions are to conduct both theoretical and applied social science research, provide technical assistance, and offer training to advance performance in policy relevant research areas. Management and research issues associated with human-resource interactions typically occur in a unique context, involve difficult to access populations, require knowledge of both natural/biological science in addition to social science, and require the skill to integrate multiple science disciplines. In response to these difficult contexts, PASA researchers apply traditional and state-of-the-art social science methods drawing from the fields of sociology, demography, economics, political science, communications, social-psychology, and applied industrial organization psychology. Social science methods work in concert with our rangeland/agricultural management, wildlife, ecology, and biology capabilities. The goal of PASA's research is to enhance natural resource management, agency functions, policies, and decision-making. Our research is organized into four broad areas of study.

    Full Text Available Blindness following a LeFort I osteotomy is a rare but extremely serious complication. Ten cases have been reported to date. None of these patients recovered vision. Optic neuropathy is believed to be the cause but the exact mechanism has not been settled. We report the first, and the only two, documented cases of complete loss of vision that recovered subsequently. The first patient was a 19-year-old male with repaired bilateral cleft lip and palate. He developed loss of vision in the right eye on the second postoperative day. The second patient was a 22-year-old male with repaired unilateral cleft lip and palate. He developed complete loss of vision in the left eye on the day of surgery. Both these patients underwent ongoing studies, which did not show any abnormalities. Both were treated with methylprednisolone. Both the patients gradually showed improvement in their vision. The first patient recovered normal vision several months postoperatively. The second patient′s vision improved to 4/60 by 4 months postoperatively. We discuss the probable mechanisms of optic nerve injury and also the possible reasons why sight was restored in these patients. This is a rare but serious complication following a fairly common procedure. Through this article we wish to create an awareness of this complication and also a possible way of avoiding such a disaster.

  15. Effects of river ice on bank morphology and riparian vegetation along Peace River, Clayhurst to Fort Vermilion

    International Nuclear Information System (INIS)

    The effects of river ice and related flooding on the bank morphology and riparian vegetation along 655 km of the Peace River from Clayhurst, British Columbia to Fort Vermilion, Alberta were studied. The river has been regulated for hydroelectric power generation since 1968 and has experienced changes in the hydrologic and ice regimes. The rate of channel adjustments under the new hydrologic regime vary longitudinally, and depend greatly on the succession of riparian vegetation. This study was conducted to determine how much of the variation in both channel adjustment and rate of riparian succession is a result of allogenic effects of ice jams. The direct physical effects of ice and the indirect effects of ice jam flooding on the channel margin were investigated. Long term ice jam severity was found to generally peak well downstream of the principal observation point. The morphology of the channel at the severe ice jam locations fit the classical ice jam criteria of confined tight meanders with several mid-channel islands and shoals. Vegetation damage was the most visible impact to the riparian environment along the Peace River. 27 refs., 1 tab., 8 figs

    Full Text Available Escherichia coli is a widespread bacterium encompassing a variety of strains, ranging from highly pathogenic strains, causing worldwide outbreaks of severe diseases to avirulent, well characterized safe laboratory strains. This study evaluated the prevalence and antibiogram profiles of E. coli pathotypes isolated from the Kat River and Fort Beaufort abstraction water. A total of 171 out of 278 confirmed E. coli isolates were positive for at least one pathogenic determinant and these included enteropathogenic E. coli (6%, enterotoxigenic E. coli (47%, uropathogenic E. coli (2%, neonatal meningitis E. coli (5%, diffusely adherent E. coli (1% and enterohaemorrhagic E. coli (1%. Interestingly, enteroinvasive and enteroaggregative E. coli were not detected. The phenotypic antibiogram profiles of the isolates revealed that all were resistant to penicillin G, while 98% and 38% of the pathotypes were resistant to ampicillin and trimethoprim-sulphamethoxazole, respectively. About 8% of the isolates were resistant to streptomycin. More than half of the isolates exhibited multiple antibiotic resistance with 44% being resistant to three antibiotics and 8% resistant to four antibiotics. We conclude that the Kat River is a reservoir of potentially virulent antibiotic resistant E. coli strains that can cause serious health risks to humans who drink raw water from this river, or in the case that consumption of treated drinking water coincides with failed drinking water processes.

  17. The growing season water balance and controls on evapotranspiration in wetland reclamation test cells Fort McMurray, Alberta

    Science.gov (United States)

    Faubert, Jean-Pascal R.

    In the oil sands mining region near Fort McMurray, Alberta, efforts to establish specific wetland reclamation techniques are underway. During the 2010 growing season, the water balance of 12 plots (cells) of different soil and vegetation treatments were studied with emphasis on understanding the controls on evapotranspiration (ET) and the effects of construction techniques. Cell hydrologic behaviour was distinct from natural wetlands due to frequent artificial irrigation. ET ranged from ˜0 6 mm day-1 to ˜8.2 mm day-1 with a mean of ˜3.2 mm day-1 and variation among the cells was attributed to the construction techniques used, specifically placement period and soil depth. ET was weakly correlated to individual environmental variables; however, multivariate statistical models revealed complex interactions among environmental variables that acted to control ET. Cumulative water balances indicated certain construction techniques produced ET rates comparable to natural wetlands, which may be an important factor in improving the long-term sustainability of reclaimed wetlands.

    Pacific Northwest National Laboratory (PNNL) conducted a proof-of-principle test at the Fort Lewis Logistics Center to determine the feasibility of using the In Situ Redox Manipulation (ISRM) technology for remediating groundwater contaminated with dissolved trichloroethylene (TCE). ISRM creates a permeable treatment zone in the subsurface to remediate redox-sensitive contaminants in groundwater. The permeable treatment zone is formed by injecting a chemical reducing agent (sodium dithionite with pH buffers) into the aquifer through a well to reduce the naturally occurring ferric iron in the sediments to ferrous iron. Once the reducing agent is injected and given sufficient time to react with aquifer sediments, residual chemicals and reaction products are withdrawn from the aquifer through the same well used for the injection. Redox-sensitive contaminants such as TCE, moving through the treatment zone under natural groundwater flow conditions, are destroyed. TCE is degraded via reductive dechlorination within the ISRM treatment zone to benign degradation products (i.e., acetylene, ethylene). Prior to the proof-of-principle field test, the ISRM technology was successfully demonstrated in laboratory experiments for the reductive dechlorination of dissolved TCE using sediments from the Fort Lewis site. The Logistics Center was placed on the National Priorities List in December 1989 because of TCE contamination in groundwater beneath the site. A Federal Facilities Agreement between the Army, the U.S. Environmental Protection Agency, and the Washington State Department of Ecology became effective in January 1990, and a Record of Decision (ROD) was signed in September 1990. The major components of the ROD included installation of two pump-and-treat systems for the upper aquifer and further investigation of the lower aquifer and other potential sources of contamination. The pump-and-treat systems became operational in August 1995. Fort Lewis asked PNNL to provide

    Pacific Northwest National Laboratory conducted a proof-of-principle test at the Fort Lewis Logistics Center to determine the feasibility of using the innovative remedial technology In Situ Redox Manipulation (ISRM) to treat groundwater contaminated with dissolved TCE. ISRM creates a permeable treatment zone in the subsurface to remediate redox-sensitive contaminants in groundwater. The permeable treatment zone is created by injecting a chemical reducing agent (sodium dithionite with pH buffers) into the aquifer through a well to chemically reduce the naturally occurring ferric iron in the sediments to ferrous iron. Once the reducing agent has been given sufficient time to react with aquifer sediments, residual chemicals and reaction products are withdrawn through the same well. Redox-sensitive contaminants such as TCE, moving in a dissolved-phase plume through the treatment zone, are destroyed. TCE is degraded via reductive dechlorination within the treatment zone to benign degradation products (acetylene, ehtylene). Analyses of sediment samples collected from post-test boreholes showed a high degree of iron reduction, which confirmed the effectiveness of the treatment zone.

    The analysis and modeling of investment behavior in the development of hydrothermal electric power facilities are reported. This investment behavior reflects a degree of sensitivity to public policy alternatives concerning taxation and regulation of the resource and its related energy conversion facilities. The objective of the current research is to provide a realistic and theoretically sound means for estimating the impacts of such public policy alternatives. A stochastic simulation model was developed which offers an efficient means for site-specific investment analysis of private sector firms and investors. The results of the first year of work are discussed including the identification, analysis, quantification and modeling of: a decision tree reflecting the sequence of procedures, timing and stochastic elements of hydrothermal resource development projects; investment requirements, expenses and revenues incurred in the exploration, development and utilization of hydrothermal resources for electric power generation; and multiattribute investment decision criteria of the several types of firms in the geothermal industry. An application of the investment model to specific resource sites in the state of Utah is also described. Site specific data for the Known Geothermal Resource Areas of Roosevelt Hot Springs and Cove Fort-Sulphurdale are given together with hypothesized generation capacity growth rates.

    At the request of the U.S. Forest Service, an instream flow assessment was conducted at Cherry Creek, Ariz., to investigate habitat for native and introduced fish species and to describe the beneficial use of a possible instream flow water right. The U.S. Geological Survey (USGS) Fort Collins Science Center performed an intensive field study of two sections of Cherry Creek in September 2008 to provide base data for hydrodynamic simulation of the flow conditions in the stream. The USGS Arizona Cooperative Fish and Wildlife Research Unit, at the University of Arizona School of Natural Resources, conducted a survey of the habitat requirements of the resident fish species in Cherry Creek and provided the habitat suitability criteria used in this study. The habitat suitability criteria were combined with hydrodynamic simulation results to quantify fish habitat for the full range of daily flow experienced in the creek and to produce maps of habitat occurrence for those flows. The flow record at the Cherry Creek stream gage was used to generate habitat response values over time. The long-term habitat response was incorporated into an Excel (Registered) spreadsheet to allow evaluation of habitat occurrence with and without an instream water right under different hypothetical water withdrawal scenarios. The spreadsheet displays information about the time sequence of habitat events, the duration of critical events, and habitat retention.

  2. Fort Devens: Cold Climate Market-Rate Townhomes Targeting HERS Index of 40, Harvard, Massachusetts (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2013-11-01

    Achieving aggressive energy efficiency targets requires tight coordination and clear communication among owners, designers, builders, and subcontractors. For this townhome project, MassDevelopment, the quasi-governmental agency owner, selected Metric Development of Boston, teaming with the U.S. Department of Energy (DOE) Consortium for Advanced Residential Buildings (CARB) and Cambridge Seven Architects, to build very high performing market-rate homes. Fort Devens is part of a decommissioned army base in working-class Harvard, Massachusetts, approximately one hour northwest of Boston. The team proposed 12 net zero energy-ready townhomes, meaning that the application of renewable energy systems would result in annual net zero energy use in the homes. The homes were also designed to achieve a Home Energy Rating System (HERS) Index Score of 41 before adding renewables. For this project, CARB drew on its experience working with Rural Development Inc. on a series of affordable townhomes in northern Massachusetts. The team carefully planned the site to maximize solar access, daylighting, and efficient building forms. The basic strategy was to design a very efficient thermal enclosure while minimizing incremental cost increases compared with standard construction. Using BEopt modeling software, the team established the requirements of the enclosure and investigated multiple assembly options. They settled on double-wall construction with dense-pack cellulose fill. High performance vinyl windows (U-0.24, solar heat gain coefficient [SHGC]-0.22), a vented R-59 attic, and exceptional air sealing completed the package.

  3. Technical and regulatory review of the Rover nuclear fuel process for use on Fort St. Vrain fuel

    International Nuclear Information System (INIS)

    This report describes the results of an analysis for processing and final disposal of Fort St. Vrain (FSV) irradiated fuel in Rover-type equipment or technologies. This analysis includes an evaluation of the current Rover equipment status and the applicability of this technology in processing FSV fuel. The analyses are based on the physical characteristics of the FSV fuel and processing capabilities of the Rover equipment. Alternate FSV fuel disposal options are also considered including fuel-rod removal from the block, disposal of the empty block, or disposal of the entire fuel-containing block. The results of these analyses document that the current Rover hardware is not operable for any purpose, and any effort to restart this hardware will require extensive modifications and re-evaluation. However, various aspects of the Rover technology, such as the successful fluid-bed burner design, can be applied with modification to FSV fuel processing. The current regulatory climate and technical knowledge are not adequately defined to allow a complete analysis and conclusion with respect to the disposal of intact fuel blocks with or without the fuel rods removed. The primary unknowns include the various aspects of fuel-rod removal from the block, concentration of radionuclides remaining in the graphite block after rod removal, and acceptability of carbon in the form of graphite in a high level waste repository

  4. Energy and water exchange from a saline-sodic overburden restoration cover, Fort McMurray, Alberta

    International Nuclear Information System (INIS)

    The Canadian oil sand mining industry takes responsibility for restoring mining areas to an equivalent level that existed before mining occurred. During this process, the surface-vegetation-atmosphere continuum is dramatically altered, creating few similarities to the boreal forest that existed prior to mining. Using the eddy covariance method, a study of the integrated salt and water balance of a saline-sodic overburden pile at Syncrude Canada Ltd.'s Mildred Lake mine north of Fort McMurray, Alberta was undertaken in order to measure the surface energy balance for three summers (2003 - 2005) with different climatic and phenological conditions. The objective of this study was to document how evapotranspiration and energy partitioning varied inter-annually during the growing season atop the restoration cover and to relate the portioning of energy at the surface to environmental and physiological variables. The paper described the site and measurement specifics and also presented the results and discussion. Results were organized under the following topics: climate; soil moisture and suction; leaf area index and vegetation; surface energy balance; evapotranspiration; and controls on evapotranspiration. It was concluded that results from this study have important implications for recovery strategies, as the availability water for plant growth, the movement and migration of salts and percolating water for deep drainage all depend on accurate quantification of evapotranspiration. 9 refs., 1 tab

  5. Irradiation performance of Fort St. Vrain high-temperature gas-cooled reactor fuel in capsule F-30

    International Nuclear Information System (INIS)

    Representative production fuel fabricated for the Fort St. Vrain (FSV) high-temperature gas-cooled reactor (HTGR) was tested in capsule F-30. The irradiation conditions experienced by the fuel encompassed the FSV service conditions designed for a 6-yr fuel cycle. Fuel specimens were irradiated at temperatures ranging from 825 to 12500C (1098 to 1523 K) and to a peak fast-neutron exposure of 9.4 x 1025 n/m2 (E greater than 29 fJ)/sub HTGR/, which is 18 percent beyond the design FSV peak fast-neutron exposure. In-pile fission gas release measurements and postirradiation examination indicated good irradiation stability of the fuel specimens. The 13 bonded fuel rods were intact, and their irradiation-induced dimensional changes were in good agreement with dimensional change curves used in the FSV core design. Total fuel particle failure fractions determined by visual examination, metallography, and fission gas release measurements were consistent with the criterion of less than 1 percent failure at peak exposure conditions assumed in FSV design and licensing evaluations. Fuel performance in the FSV reactor was evaluated using the capsule F-30 irradiation results. The good irradiation behavior of production fuel in this test gives a high degree of confidence in the performance of the FSV core throughout its lifetime and demonstrates the conservative nature of the FSV fuel particle design

  6. Fort St. Vrain Nuclear Generating Station Environmental Radiation Surveillance Program. Summary report, third and fourth quarters, July-December 1982

    International Nuclear Information System (INIS)

    During the second half of 1982 the Fort St. Vrain Nuclear Generating Station produced power of 2.4 x that in the previous 6 month reporting period. The reactor did not operate during the first 3.5 months of 1982. Radioactivity released by normal effluent routes, however, was not negligible during the shut down period. This is due to scheduled clean-up and maintenance operations. A complete and detailed listing of radioactivity released by all effluent routes may be found in the Public Service Company of Colorado semi-annual Effluent Release Report to the U.S.N.R.C. When possible in this report any correlation of radioactivity in environmental samples with the effluent release data is discussed. The environmental sampling and analysis program was essentially identical to that used in the most recent reporting periods. Essentially all radioactivity data measured on this project are near background levels and, more importantly, near the minimum detectable activity (MDA) levels for each radionuclude and sample type

    From 2002 to 2004, more than 500 micropiles were installed at Syncrude's Mildred Lake Upgrader Expansion Facility north of Fort McMurray, Alberta. The site is underlain by sand and gravel fill overlying sand, clay till and oilsand containing some clay shale and cemented siltstone stringers. The micropiles were required to support the installation of new equipment in areas where conventional auger piling rigs could not access. The micropiles augmented the vertical compression and the uplift capacity of existing bored concrete pile groups. According to Federal Highway Administration's Micropile Design and Construction Guidelines, micropiles can be either displacement piles or replacement tiles. In this project, the micropiles were the replacement type which were placed within previously drilled holes. They were combined with pressured grouting to increase the pile surface area by displacing the surrounding soil. This paper described the site conditions, the micropile design and installation. Design load tests were described with reference to verification tests and creep tests. Both the compression and tension piles could support design loads of 240 kN and 265 kN respectively. Creep tests rates were less than 1 mm per log cycle. Proof test results confirmed that the micropiles met the specified acceptable design load criteria. 5 refs., 1 tab., 6 figs.

  8. Re-licensing fort ST. Vrain: How the HTGR design basis was rediscovered - HTR2008-58030

    International Nuclear Information System (INIS)

    Over its 1968-1988 life, PSCo re-licensed the Fort St. Vrain (FSV) High-temperature Gas Reactor (HTGR) for light water reactor (LWR) technology requirements. Estimates of the financial losses associated with the plant range from $500 million to $2 billion in 1980 dollars. Colorado ratepayers, the shareholders of Gulf General Atomics and its corporate successors - General Atomics, GA Technologies or just GA and Public Service Company of Colorado (PSCo) bore these losses. Two critical plant issues required solution for the plant's economic success - (1) the high-cost of 93% enriched uranium fuel and (2) low unit availability. While fuel costs were beyond utility control, low availability was controllable, yet remained unresolved. Commercially isolated for twenty years, PSCo shut the plant down in 1988. Economic success of future HTGRs depends upon avoiding similar complications. This paper examines the issues that made FSV uneconomic, including those fundamental to HTGR technology and others attributable to the utility operator and its culture. Knowing the history of FSV and HTGR design, designers should anticipate reasonable challenges. Preparations will help manage future HTGR risks, costs, and assure operating success. Regulators and industry can assure more effective, economic operations in the next round of HTGR designs. (authors)

    Water resource scarcity around the world is driving the need for the development of simulation models that can assist in water resources management. Transboundary water resources are receiving special attention because of the potential for conflict over scarce shared water resources. The Rio Grande/Rio Bravo along the U.S./Mexican border is an example of a scarce, transboundary water resource over which conflict has already begun. The data collection and modeling effort described in this report aims at developing methods for international collaboration, data collection, data integration and modeling for simulating geographically large and diverse international watersheds, with a special focus on the Rio Grande/Rio Bravo. This report describes the basin, and the data collected. This data collection effort was spatially aggregated across five reaches consisting of Fort Quitman to Presidio, the Rio Conchos, Presidio to Amistad Dam, Amistad Dam to Falcon Dam, and Falcon Dam to the Gulf of Mexico. This report represents a nine-month effort made in FY04, during which time the model was not completed.

    In 1982 the Centers for Disease Control published a set of recommendations and measures to protect persons working in health care settings or performing mortician services from possible exposure to the human immunodeficiency virus. This study of a number of funeral homes in the Fort Worth area was designed to determine the level of exposure of funeral home workers to blood and other body fluids and also to assess existing protective measures and practices in the industry. Workers in 22 funeral home franchises were surveyed with a predesigned questionnaire. Eighty-five responses from 20 of the 22 establishments were received. All 85 respondents admitted exposure of varying degrees to blood and body fluids. Sixty persons (70%) admitted heavy exposure, that is, frequent splashes. Analysis of the responses showed that 81 of 85 (95.3%) persons consistently wore gloves while performing tasks that might expose them to blood or other body fluids. Of the 60 persons who were heavily exposed, 43 wore long-sleeved gowns, 27 wore waterproof aprons, 17 surgical masks, and 15 goggles. The study further revealed that 52.9% (45/85) of the respondents had sustained accidental cuts or puncture wounds on the job. In light of these findings it is important to target educational efforts to persons in this industry to help them minimize their risks of infection with blood and body fluid borne infections.

    Full Text Available This study investigated strontium isotopes in the dental enamel of 32 human skeletons from Forte Marechal Luz sambaqui (shellmound, Santa Catarina, Brazil, aiming at identifying local and non-local individuals. The archeological site presents pot sherds in the uppermost archeological layers. Dental enamel was also examined from specimens of terrestrial fauna (87Sr/86Sr = 0. 71046 to 0. 71273 and marine fauna (87Sr/86Sr = 0. 70917. The 87Sr/86Sr isotope ratio for individuals classified as locals ranged from 0. 70905 to 0. 71064 and was closer to the isotope ratio of the seawater than to the ratio of the terrestrial fauna, indicating a strong influence of marine strontium on the inhabitants of this sambaqui. The results indicate the existence of three non-local individuals (87Sr/86Sr = 0. 70761 to 0. 70835, buried in both the level without pottery and the layer with pottery, possibly originated from the Santa Catarina Plateau, close to the municipality of Lages, or from the Curitiba Plateau. The occurrence of a slight difference between the isotope ratios of local individuals buried in the archeological layer without pottery, when compared to those in the layer with pottery, suggests a possible change in dietary patterns between these two moments in the site's occupationO presente estudo investigou isótopos de estrôncio em esmalte dentário de 32 remanescentes humanos do sambaqui do Forte Marechal Luz, Santa Catarina, Brasil, com o objetivo de identificar indivíduos locais e não-locais.

    According to the American Geological Institute's Status of Recent Geoscience Graduates, 2014, underrepresented minorities (URMs) make up only 7%, 5%, and 2% of graduates at the BS/BA, MA/MS, and Ph.D levels, respectively. Recruiting academically-talented URMs to major in the geosciences instead of majoring in other fields such as medicine, law, business, or engineering is a major undertaking. Numerous factors may contribute as to why few URMs choose geoscience careers. To address the underrepresentation of URMs in the geosciences 1992, the Cooperative Developmental Energy Program (CDEP) of Fort Valley State University (FVSU) and the College of Geosciences at the University of Oklahoma (OU) implemented a 3 + 2 dual degree program specifically in geology and geophysics. Since 1992, FVSU-CDEP has added the University of Texas at Austin (2004), Pennsylvania State University (2005), University of Arkansas (2010), and the University of Nevada at Las Vegas (2015) as partners to offer degrees in geology and geophysics. The dual degree programs consist of students majoring in chemistry or mathematics at FVSU for the first three years and transferring to one of the above partnering universities for years four and five to major in geology or geophysics. Upon completion of the program, students receive a BS degree in chemistry or mathematics from FVSU and a BS degree in geology or geophysics from a partnering university. CDEP has been responsible for recruiting 33 URMs who have earned BS degrees in geology or geophysics. Females constitute 50% of the graduates which is higher than the national average. Also, 56% of these graduates have earned the MS degree and 6% have earned the Ph.D. Currently, 60% of these graduates are employed with oil and gas companies; 20% work for academia; 12% work for governmental agencies; 6 % are professionals with environmental firms; and 2% of the graduate's employment is unknown.

    Population models are essential components of large-scale conservation and management plans for the federally endangered Golden-cheeked Warbler (Setophaga chrysoparia; hereafter GCWA). However, existing models are based on vital rate estimates calculated using relatively small data sets that are now more than a decade old. We estimated more current, precise adult and juvenile apparent survival (Φ) probabilities and their associated variances for male GCWAs. In addition to providing estimates for use in population modeling, we tested hypotheses about spatial and temporal variation in Φ. We assessed whether a linear trend in Φ or a change in the overall mean Φ corresponded to an observed increase in GCWA abundance during 1992-2000 and if Φ varied among study plots. To accomplish these objectives, we analyzed long-term GCWA capture-resight data from 1992 through 2011, collected across seven study plots on the Fort Hood Military Reservation using a Cormack-Jolly-Seber model structure within program MARK. We also estimated Φ process and sampling variances using a variance-components approach. Our results did not provide evidence of site-specific variation in adult Φ on the installation. Because of a lack of data, we could not assess whether juvenile Φ varied spatially. We did not detect a strong temporal association between GCWA abundance and Φ. Mean estimates of Φ for adult and juvenile male GCWAs for all years analyzed were 0.47 with a process variance of 0.0120 and a sampling variance of 0.0113 and 0.28 with a process variance of 0.0076 and a sampling variance of 0.0149, respectively. Although juvenile Φ did not differ greatly from previous estimates, our adult Φ estimate suggests previous GCWA population models were overly optimistic with respect to adult survival. These updated Φ probabilities and their associated variances will be incorporated into new population models to assist with GCWA conservation decision making.

  15. Evaluation of Codisposal Viability for TH/U Carbide (Fort Saint Vrain HTGR) DOE-Owned Fuel

    International Nuclear Information System (INIS)

    There are more than 250 forms of US Department of Energy (DOE)-owned spent nuclear fuel (SNF). Due to the variety of the spent nuclear fuel, the National Spent Nuclear Fuel Program has designated nine representative fuel groups for disposal criticality analyses based on fuel matrix, primary fissile isotope, and enrichment. The Fort Saint Vrain reactor (FSVR) SNF has been designated as the representative fuel for the Th/U carbide fuel group. The FSVR SNF consists of small particles (spheres of the order of 0.5-mm diameter) of thorium carbide or thorium and high-enriched uranium carbide mixture, coated with multiple, thin layers of pyrolytic carbon and silicon carbide, which serve as miniature pressure vessels to contain fission products and the U/Th carbide matrix. The coated particles are bound in a carbonized matrix, which forms fuel rods or ''compacts'' that are loaded into large hexagonal graphite prisms. The graphite prisms (or blocks) are the physical forms that are handled in reactor loading and unloading operations, and which will be loaded into the DOE standardized SNF canisters. The results of the analyses performed will be used to develop waste acceptance criteria. The items that are important to criticality control are identified based on the analysis needs and result sensitivities. Prior to acceptance to fuel from the Th/U carbide fuel group for disposal, the important items for the fuel types that are being considered for disposal under the Th/U carbide fuel group must be demonstrated to satisfy the conditions determined in this report

    The Fort Berthold Indian Reservation, inhabited by the Arikara, Mandan and Hidatsa Tribes (now united to form the Three Affiliated Tribes) covers a total area of 1530 mi{sup 2} (980,000 acres). The Reservation is located approximately 15 miles east of the depocenter of the Williston basin, and to the southeast of a major structural feature and petroleum producing province, the Nesson anticline. Several published studies document the widespread existence of mature source rocks, favorable reservoir/caprock combinations, and production throughout the Reservation and surrounding areas indicating high potential for undiscovered oil and gas resources. This technical assessment was performed to better define the oil exploration opportunity, and stimulate exploration and development activities for the benefit of the Tribes. The need for this assessment is underscored by the fact that, despite its considerable potential, there is currently no meaningful production on the Reservation, and only 2% of it is currently leased. Of particular interest (and the focus of this study) is the area under the Lake Sakakawea (formed as result of the Garrison Dam). This 'reservoir taking' area, which has never been drilled, encompasses an area of 150,000 acres, and represents the largest contiguous acreage block under control of the Tribes. Furthermore, these lands are Tribal (non-allotted), hence leasing requirements are relatively simple. The opportunity for exploration success insofar as identifying potential leads under the lake is high. According to the Bureau of Land Management, there have been 591 tests for oil and gas on or immediately adjacent to the Reservation, resulting in a total of 392 producing wells and 179 plugged and abandoned wells, for a success ratio of 69%. Based on statistical probability alone, the opportunity for success is high.

    Background Le Fort-based, maxillofacial allotransplantation is a reconstructive alternative gaining clinical acceptance. However, the vast majority of single-jaw transplant recipients demonstrate less-than-ideal skeletal and dental relationships with suboptimal aesthetic harmony. The purpose of this study was to investigate reproducible cephalometric landmarks in a large animal model, where refinement of computer-assisted planning, intra-operative navigational guidance, translational bone osteotomies, and comparative surgical techniques could be performed. Methods Cephalometric landmarks that could be translated into the human craniomaxillofacial skeleton, and would remain reliable following maxillofacial osteotomies with mid-facial alloflap inset, were sought on six miniature swine. Le Fort I-and Le Fort III-based alloflaps were harvested in swine with osteotomies, and all alloflaps were either auto-replanted or transplanted. Cephalometric analyses were performed on lateral cephalograms pre- and post-operatively. Critical cephalometric data sets were identified with the assistance of surgical planning and virtual prediction software, and evaluated for reliability and translational predictability. Results Several pertinent landmarks and human analogues were identified including pronasale (PRN), zygion (Zy), parietale (PA), gonion (GO), gnathion (GN), lower incisior base (LIB), and alveolare (ALV). PA-PRN-ALV and PA-PRN-LIB were found to be reliable correlates of SNA and SNB measurements in humans, respectively. Conclusions There is a set of reliable cephalometric landmarks and measurement angles pertinent for utilization within a translational large animal model. These craniomaxillofacial landmarks will allow us to develop novel navigational software technology, improve our cutting guide designs, and explore new avenues for investigation and collaboration.

  3. An integrated paleomagnetic and diagenetic investigation of the Barnett shale and underlying Ellenburger Group carbonates, Fort Worth Basin, Texas

    Science.gov (United States)

    Dennie, Devin P.

    The Ordovician Ellenburger Group carbonates are extensively karsted and brecciated throughout portions of the western half of the Fort Worth Basin, Texas, where it underlies the Mississippian Barnett Shale gas reservoir and source rock. An integrated geochemical/petrographic, paleomagnetic and rock magnetic study was conducted to better understand the nature and timing of diagenetic events in the unit. Samples from three scribe oriented conventional drill cores of the uppermost Ellenburger Group carbonates were analyzed for their diagenetic and paleomagnetic properties. Thermal demagnetization of samples from both units reveals a low-temperature steeply downward viscous remanent magnetization (VRM) as well as several components that are removed at higher temperatures (200-540°C). The higher temperature components reside in magnetite and are interpreted as chemical remanent magnetizations (CRMs) based on low burial temperatures. The specimen directions are streaked from an easterly and shallow direction to a southerly and shallow direction. The modern VRM was used to orient the CRM data for one of the wells and to test the scribe orienting method. The results confirm that the streak of directions is real. The streak disappears when the directions are grouped by diagenetic facies. Specimens from clasts in the karst breccia facies contain a CRM with easterly declinations and shallow inclinations that fails a conglomerate test and has an Ordovician pole. A mixed dolomite-limestone with shale filled fracture facies contains a pole which falls off of but close to the Late Mississippian-Early Pennsylvanian part of the apparent polar wander path. A group of facies (crystalline dolomite, wavy bedded to argillaceous dolomite, mottled, burrowed dolomite with fine grained breccia facies, and clastic-rich peritidal carbonates) contains a Late Permian-Early Triassic CRM. Dolomites with vug-fill solution-reprecipitation features contain a Late Triassic-Jurassic CRM. The results

    Viability for the development of an engineered geothermal system (EGS) in the oilsands region near Fort McMurray, Alberta, is investigated by studying the structure of the Precambrian basement rocks with magnetotellurics (MT). MT data were collected at 94 broad-band stations on two east-west profiles. Apparent resistivity and phase data showed little variation along each profile. The short period MT data detected a 1-D resistivity structure that could be identified as the shallow sedimentary basin underlain by crystalline basement rocks to a depth of 4-5 km. At lower frequencies a strong directional dependence, large phase splits, and regions of out-of-quadrant (OOQ) phase were detected. 2-D isotropic inversions of these data failed to produce a realistic resistivity model. A detailed dimensionality analysis found links between large phase tensor skews (˜15°), azimuths, OOQ phases and tensor decomposition strike angles at periods greater than 1 s. Low magnitude induction vectors, as well as uniformity of phase splits and phase tensor character between the northern and southern profiles imply that a 3-D analysis is not necessary or appropriate. Therefore, 2-D anisotropic forward modelling was used to generate a resistivity model to interpret the MT data. The preferred model was based on geological observations of outcropping anisotropic mylonitic basement rocks of the Charles Lake shear zone, 150 km to the north, linked to the study area by aeromagnetic and core sample data. This model fits all four impedance tensor elements with an rms misfit of 2.82 on the southern profile, and 3.3 on the northern. The conductive phase causing the anisotropy is interpreted to be interconnected graphite films within the metamorphic basement rocks. Characterizing the anisotropy is important for understanding how artificial fractures, necessary for EGS development, would form. Features of MT data commonly interpreted to be 3-D (e.g. out of OOQ phase and large phase tensor skew) are

  6. High-resolution Rainfall Mapping in Dallas-Fort Worth (DFW) Urban Network of Radars at Multiple Frequencies

    2015-04-01

    Urban flash flood is one of the most commonly encountered hazardous weather phenomena. Unfortunately, the rapid urbanization has made the densely populated areas even more vulnerable to flood risks. Hence, accurate and timely monitoring of rainfall at high spatiotemporal resolution is critical to severe weather warning and civil defense, especially in urban areas. However, it is still challenging to produce high-resolution products based on the large S-band National Weather Service (NWS) Next-Generation Weather Radar (NEXRAD), due to the sampling limitations and Earth curvature effect. Since 2012, the U.S. National Science Foundation Engineering Research Center (NSF-ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA) has initiated the development of Dallas-Fort Worth (DFW) radar remote sensing network for urban weather hazards mitigation. The DFW urban radar network consists of a combination of high-resolution X-band radars and a standard NWS NEXRAD radar operating at S-band frequency. High-resolution quantitative precipitation estimation (QPE) is one of the major research goals in the deployment of this urban radar network. It has been shown in the literature that the dual-polarization radar techniques can improve the QPE accuracy over traditional single-polarization radars by rendering more measurements to enhance the data quality, providing more information about rain drop size distribution (DSD), and implying more characteristics of different hydrometeor types. This paper will present the real-time dual-polarization CASA DFW QPE system, which is developed via fusion of observations from both the high-resolution X band radar network and the S-band NWS radar. The specific dual-polarization rainfall algorithms at different frequencies (i.e., S- and X-band) will be described in details. In addition, the fusion methodology combining observations at different temporal resolution will be presented. In order to demonstrate the capability of rainfall

    The responses of the following carbonate materials to shock loading and release have been measured: Indiana limestone (18% porosity; saturated and dry), Jeffersonville/Louisville Limestones (Fort Knox limestone) (variable dolomitization, low porosity), Danby Marble (essentially pure calcite; low porosity), and a limestone from the Utah Test and Training Range (low porosity, with 22% silica). Various experimental configurations were used, some optimized to yield detailed waveform information, others to yield a clean combination of Hugoniot states and release paths. All made use of velocity interferometry as a primary diagnostic. The stress range of 0 - 20 GPa was probed (in most cases, emphasizing the stress range 0 -10 GPa). The primary physical processes observed in this stress regime were material strength, porosity, and polymorphic phase transitions between the CaCO{sub 3} phases I, II, III and VI. Hydration was also a significant reaction under certain conditions. The Indiana Limestone studies in particular represent a significant addition to the low-pressure database for porous limestone. Temperature dependence and the effect of freezing were assessed for the Fort Knox limestone. Experimental parameters and detailed results are provided for the 42 impact tests in this series.

    Full Text Available OBJETIVO: Ânion gap corrigido e íon gap forte são usados comumente para estimar os ânions não medidos. Avaliamos o desempenho do ânion gap corrigido para albumina, fosfato e lactato na predição do íon gap forte em uma população mista de pacientes enfermos graves. Formulamos a hipótese de que o ânion gap corrigido para albumina, fosfato e lactato seria um bom preditor do íon gap forte, independentemente da presença de acidose metabólica. Além disso, avaliamos o impacto do íon gap forte por ocasião da admissão na mortalidade hospitalar. MÉTODOS: Incluímos 84 pacientes gravemente enfermos. A correlação e a concordância entre o ânion gap corrigido para albumina, fosfato e lactato e o íon gap forte foi avaliada utilizando-se os testes de correlação de Pearson, regressão linear, plot de Bland-Altman e pelo cálculo do coeficiente de correlação interclasse. Foram realizadas duas análises de subgrupos: uma para pacientes com excesso de base -2mEq/L (grupo com alto excesso de base. Foi realizada uma regressão logística para avaliar a associação entre os níveis de íon gap forte na admissão e a mortalidade hospitalar. RESULTADOS: Houve correlação muito forte e uma boa concordância entre o ânion gap corrigido para albumina, fosfato e lactato e o íon gap forte na população geral (r2=0,94; bias 1,40; limites de concordância de -0,75 a 3,57. A correlação foi também elevada nos grupos com baixo excesso de base (r2=0,94 e alto excesso de base (r2=0,92. Estavam presentes níveis elevados de íon gap forte em 66% da população total e 42% dos casos do grupo alto excesso de. Íon gap forte não se associou com a mortalidade hospitalar, conforme avaliação pela regressão logística. CONCLUSÃO: O ânion gap corrigido para albumina, fosfato e lactato e o íon gap forte tiveram uma excelente correlação.

    Natural attenuation processes include biological degradation, by which microorganisms break down contaminants into simpler product compounds; adsorption of contaminants to soil particles, which decreases the mass of contaminants dissolved in ground water; and dispersion, which decreases dissolved contaminant concentrations through dilution. The primary objectives of this study are to (1) assess the degree to which such natural processes are attenuating chlorinated-hydrocarbon contamination in ground water, and (2) evaluate the effects of ground-water/surface-water interactions on natural-attenuation processes in the area of the former East and West Quartermasters Fueling Systems for Fort Wainwright, Alaska. The study will include investigations of the hydrologic, geochemical, and microbiological processes occurring at this site that influence the transport and fate of chlorinated hydrocarbons in ground water. To accomplish these objectives, a data-collection program has been initiated that includes measurements of water-table elevations and the stage of the Chena River; measurements of vertical temperature profiles within the subsurface; characterization of moisture distribution and movement in the unsaturated zone; collection of ground-water samples for determination of both organic and inorganic chemical constituents; and collection of ground-water samples for enumeration of microorganisms and determination of their potential to mineralize contaminants. We will use results from the data-collection program described above to refine our conceptual model of hydrology and contaminant attenuation at this site. Measurements of water-table elevations and river stage will help us to understand the magnitude and direction of ground-water flow and how changes in the stage of the Chena River affect ground-water flow. Because ambient ground water and surface water typically have different temperature characteristics, temperature monitoring will likely provide further insight

    Battelle Energy Alliance, LLC, managing and operating contractor for the U.S. Department of Energy’s Idaho National Laboratory, is the lead laboratory for the U.S. Department of Energy’s Advanced Vehicle Testing. Battelle Energy Alliance, LLC contracted with Intertek Testing Services, North America (ITSNA) to collect data on federal fleet operations as part of the Advanced Vehicle Testing Activity’s Federal Fleet Vehicle Data Logging and Characterization study. The Advanced Vehicle Testing Activity study seeks to collect data to validate the use of advanced electric drive vehicle transportation. This report focuses on the Fort Vancouver National Historic Site (FVNHS) fleet to identify daily operational characteristics of select vehicles and report findings on vehicle and mission characterizations to support the successful introduction of electric vehicles (EVs) into the agencies’ fleet. Individual observations of the selected vehicles provided the basis for recommendations related to EV adoption and whether a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV) (collectively plug-in electric vehicles) could fulfill the mission requirements. FVNHS identified three vehicles in its fleet for consideration. While the FVNHS vehicles conduct many different missions, only two (i.e., support and pool missions) were selected by agency management to be part of this fleet evaluation. The logged vehicles included a pickup truck and a minivan. This report will show that BEVs and PHEVs are capable of performing the required missions and providing an alternative vehicle for both mission categories, because each has sufficient range for individual trips and time available each day for charging to accommodate multiple trips per day. These charging events could occur at the vehicle’s home base, high-use work areas, or in intermediate areas along routes that the vehicles frequently travel. Replacement of vehicles in the current fleet would result in

    This report provides a map and detailed descriptions of geologic formations for a 1,250 square mile region in the Rawlins-Little Snake River coal field in the eastern part of the Washakie and Great Divide Basins of south-central Wyoming. Mapping of geologic formations and coal beds was conducted at a scale of 1:24,000 and compiled at a scale of 1:100,000. Emphasis was placed on coal-bearing strata of the China Butte and Overland Members of the Paleocene Fort Union Formation. Surface stratigraphic sections were measured and described and well logs were examined to determine the lateral continuity of individual coal beds; the coal-bed stratigraphy is shown on correlation diagrams. A structure contour and overburden map constructed on the uppermost coal bed in the China Butte Member is also provided.

    The objectives of this project are to define undrained or incompletely drained reservoir compartments controlled primarily by depositional heterogeneity in a low-accommodation, cratonic Midcontinent depositional setting, and, afterwards, to develop and transfer to producers strategies for infield reserve growth of natural gas. Integrated geologic, geophysical, reservoir engineering, and petrophysical evaluations are described in complex difficult-to-characterize fluvial and deltaic reservoirs in Boonsville (Bend Conglomerate Gas) field, a large, mature gas field located in the Fort Worth Basin of North Texas. The purpose of this project is to demonstrate approaches to overcoming the reservoir complexity, targeting the gas resource, and doing so using state-of-the-art technologies being applied by a large cross section of Midcontinent operators.

  18. Investigation into the causes and consequences of the malfunction of static shutdown seal S/N 3 in Fort St. Vrain circulator C2102 from the ''D''' penetration

    International Nuclear Information System (INIS)

    The helium circulators for the Fort St. Vrain nuclear power station incorporate bellows-actuated shutdown seals. Circulator C2102 was removed in March 1976 from its penetration following a suspected failure of the bellows actuator or its supply line, as evidenced by a substantial leak. The circulator was returned to San Diego for disassembly and inspection. Examination of the shutdown seal revealed the failure to be a circumferential crack in the inner bellows in the crown of the first convolution adjacent to the fixed end. Investigation of the failure showed that the crack was most probably initiated by repeated overextension of the bellows prior to installation in the circulator and was propagated by shorter stroke cyclic loading. It was concluded that the conditions leading to failure were abnormal and unique to this particular seal and circulator. Therefore, the failure does not appear to be indicative of a generic problem

    In a paper from 2006, Couder and Fort [1] describe a version of the famous double slit experiment performed with drops bouncing on a vibrated fluid surface, where interference in the particle statistics is found even though it is possible to determine unambiguously which slit the "walking" drop passes. It is one of the first papers in an impressive series, showing that such walking drops closely resemble de Broglie waves and can reproduce typical quantum phenomena like tunneling and quantized states [2-13]. The double slit experiment is, however, a more stringent test of quantum mechanics, because it relies upon superposition and phase coherence. In the present comment we first point out that the experimental data presented in [1] are not convincing, and secondly we argue that it is not possible in general to capture quantum mechanical results in a system, where the trajectory of the particle is well-defined.

    The extraction of fossil fuels from the Alberta oil sands has been the focus of considerable attention due to its association with sizeable emissions of a variety of atmospheric pollutants, the magnitude and impacts of which are currently poorly constrained by observations. In order to more reliably estimate the magnitude and impact of these emissions, an intensive air quality measurement campaign, called "Fort McMurray Oil Sands Strategic Investigation of Local Sources" (FOSSILS), was conducted in the summer of 2013 as part of the Alberta-Canada joint oil sands monitoring program (JOSM) to identify and quantify emissions and their transformations from the Alberta oil sands. The challenge is that the region is surrounded by boreal forest, which provides a substantial background of biogenic hydrocarbons during summer. In this presentation, measurements of volatile organic compounds (VOCs) at the AMS13 ground site near Fort McKay, Alberta, from Aug 17 to Sept 6, 2013 using a commercial Griffin 450 gas chromatograph equipped with ion trap mass spectrometric detection and Tenax preconcentration are described. The combination of retention information and electron impact mass spectral data allowed unambiguous identification and quantification of the major biogenic monoterpenes, e.g., α and β-pinene, limonene, camphene, and 3Δ-carene, and of many anthropogenically derived hydrocarbons. Mixing ratios of biogenic hydrocarbons varied with time of day, temperature, and solar radiation, with maxima typically occurring at night, rationalized by nocturnal mixing heights and low mixing ratios of the nocturnal oxidants ozone (O3) and the nitrate radical (NO3). In contrast, mixing ratios of anthropogenic VOCs, e.g., benzene, toluene, ethyl benzene, and o-, p-, and m-xylene (BTEX), strongly depended on meteorological conditions, i.e., local wind direction. During episodes with high BTEX abundance, many additional high molecular weight hydrocarbons were observed which were not

    This study integrates image-processing, finite element (FE) analysis, optimization and CAM techniques to develop a bone plate that can provide precise positioning and fixation for the Le Fort I osteotomy. Two FE 3D models using commercial mini-plate and continuous bone plates were generated by integrating computed tomography images and CAD system for simulations under the worst load condition. The goal driven optimization method was used to examine the system performance using certain minimum output values for relative micro-movement between the two maxillary bone segments and stress for the bone plate to seek maximum reduction volume in a continuous plate. The simulation results indicated that the maximum stress/relative micro-movement was 1269.20MPa/133.66μm and 418.37MPa/92.37μm for the commercial straight mini-plate and continuous fixation types, respectively. The optimal design plate found the volume reduction rate reach 24.3% compared to the continuous bone plate and the decreased variations in stress/relative micro-movement were 65.14% (442.36MPa) and 29.36% (96.53μm) when compared to values obtained from the commercial mini-plate plate. The optimal bone plate can be manufactured using a 5-axes milling machine and fixed onto the freed separate maxillary segments of a rapid prototyping model to provide precise positioning/fixation and present adequate strength/stability in the Le Fort I osteotomy.

    Availability of water in the Rio Grande Basin has long been a primary concern for water-resource managers. The transport and delivery of water in the basin have been engineered by using reservoirs, irrigation canals and drains, and transmountain-water diversions to meet the agricultural, residential, and industrial demand. In contrast, despite the widespread recognition of critical water-quality problems, there have been minimal management efforts to improve water quality in the Rio Grande. Of greatest concern is salinization (concentration of dissolved solids approaching 1,000 mg/L), a water-quality problem that has been recognized and researched for more than 100 years because of the potential to limit both agricultural and municipal use. To address the issue of salinization, water-resource managers need to have a clear conceptual understanding of the sources of salinity and the factors that control storage and transport, identify critical knowledge gaps in this conceptual understanding, and develop a research plan to address these gaps and develop a salinity management program. In 2009, the U.S. Geological Survey (USGS) in cooperation with the U.S. Army Corps of Engineers (USACE), New Mexico Interstate Stream Commission (NMISC), and New Mexico Environment Department (NMED) initiated a project to summarize the current state of knowledge regarding the transport of dissolved solids in the Rio Grande between San Acacia, New Mexico, and Fort Quitman, Texas. The primary objective is to provide hydrologic information pertaining to the spatial and temporal variability present in the concentrations and loads of dissolved solids in the Rio Grande, the source-specific budget for the mass of dissolved solids transported along the Rio Grande, and the locations at which dissolved solids enter the Rio Grande. Dissolved-solids concentration data provide a good indicator of the general quality of surface water and provide information on the factors governing salinization within

  9. Metal partitioning in sediments and mineralogical controls on the acid mine drainage in Ribeira da Água Forte (Aljustrel, Iberian Pyrite Belt, Southern Portugal)

    International Nuclear Information System (INIS)

    This work focuses on the geochemical processes taking place in the acid drainage in the Ribeira da Água Forte, located in the Aljustrel mining area in the Iberian Pyrite Belt. The approach involved water and stream sediment geochemical analyses, as well as other techniques such as sequential extraction, Mössbauer spectroscopy, and X-ray diffraction. Ribeira da Água Forte is a stream that drains the area of the old mine dumps of the Aljustrel mine, which have for decades been a source of acid waters. This stream flows to the north for a little over than 10 km, but mixes with a reduced, organic-rich, high pH waste water from the municipal waste water pools of the village. This water input produces two different results in the chemistry of the stream depending upon the season: (i) in the winter season, effective water mixing takes place, and the flux of acid water from the mine dumps is continuous, resulting in the immediate precipitation of the Fe from the acid waters; (ii) during the summer season, acid drainage is interrupted and only the waste water feeds the stream, resulting in the reductive dissolution of Fe hydroxides and hydroxysulfates in the stream sediments, releasing significant quantities of metals into solution. Throughout the year, water pH stays invariably within 4.0–4.5 for several meters downstream of this mixing zone even when the source waters come from the waste water pools, which have a pH around 8.4. The coupled interplay of dissolution and precipitation of the secondary minerals (hydroxides and sulfates), keeps the system pH between 3.9 and 4.5 all along the stream. In particular, evidence suggests that schwertmannite may be precipitating and later decomposing into Fe hydroxides to sustain the stream water pH at those levels. While Fe content decreases by 50% from solution, the most important trace metals are only slightly attenuated before the solution mixes with the Ribeira do Rôxo stream waters. Concentrations of As are the only ones

  10. Results from Mobile Lab Measurements Obtained in the Barnett Shale with Emphasis on Methane and Gaseous Mercury Emissions (Fort Worth, TX)

    Our work is part of a comprehensive analysis conducted through a collaboration of ground based measurements and airborne measurements with several research groups in order to gain a better understanding of methane and mercury emissions in the Barnett Shale. It's a vast rock formation that sits in the 5,000 square miles surrounding the Fort Worth area. To get the gas to market requires an underground highway of pipelines and compression stations. Texas state records show that since 2000 the number of gas compressors in the Barnett Shale has tripled (from a few hundred to 1,300), and they're ever infringing on populated areas. Recent preliminary data reported by Pétron et al. and Tollefson et al. (from the natural-gas operations in Denver-Julesburg Basin) point to CH4 loss from the process of 4-8%, not including additional losses in the pipeline and distribution system. Additionally, Howarth et al. have conducted a comprehensive analysis of greenhouse gases (methane, in particular) emitted from shale gas as a result of hydraulic fracturing and they estimate up to 8% of all natural gas mined from shale formations leaks to the atmosphere. Not only is this cause for alarm due to the global warming potential of methane, but we would expect similar losses of additional (potentially harmful) gases, i.e., atmospheric Hg, from the extraction systems. These preliminary findings are higher than the current U.S. Environment Protection Agency (EPA) leakage estimate of 2.3 percent. Our strategy employs the use of our mobile laboratory, a four door Chevrolet Silverado pickup truck with a camper shell, outfitted with trace gas instrumentation including a Picarro G2132i and a Tekran 2537 mercury analyzer. The Picarro cavity ring down instrument has high precision and accuracy H2O, CO2, CH4, and 13δC in CH4 and CO2 with very little drift due to precise temperature and pressure controls. The Tekran mercury analyzer allows for accurate total gaseous mercury measurements via

    Uncertainties in the composition and fabrication of fuel compacts for the Fort St. Vrain (FSV) high temperature gas reactor have been studied by performing eigenvalue sensitivity studies that represent the key uncertainties for the FSV neutronic analysis. The uncertainties for the TRISO fuel kernels were addressed by developing a suite of models for an 'average' FSV fuel compact that models the fuel as (1) a mixture of two different TRISO fuel particles representing fissile and fertile kernels, (2) a mixture of four different TRISO fuel particles representing small and large fissile kernels and small and large fertile kernels and (3) a stochastic mixture of the four types of fuel particles where every kernel has its diameter sampled from a continuous probability density function. All of the discrete diameter and continuous diameter fuel models were constrained to have the same fuel loadings and packing fractions. For the non-stochastic discrete diameter cases, the MCNP compact model arranged the TRISO fuel particles on a hexagonal honeycomb lattice. This lattice-based fuel compact was compared to a stochastic compact where the locations (and kernel diameters for the continuous diameter cases) of the fuel particles were randomly sampled. Partial core configurations were modeled by stacking compacts into fuel columns containing graphite. The differences in eigenvalues between the lattice-based and stochastic models were small but the runtime of the lattice-based fuel model was roughly 20 times shorter than with the stochastic-based fuel model.

    The aim was to systematically review the maxillary incisor exposure and upper lip position changes with Le Fort I type osteotomies for advancement ± impaction with rigid internal fixation, taking into account the use of cinch sutures and VY closures. Electronic databases (Cochrane Library, Medline, Embase, and Web of Science) were searched using medical subject headings (MeSH), key words, truncations, and Boolean operators. Hand searching was also undertaken. Of 979 articles identified, 15 were included (11 retrospective, two prospective, and two unspecified). Relevant study details and outcomes were recorded on a spreadsheet, along with an assessment of their quality. In total, these studies assessed 419 patients (266 female, 118 male) with a mean age of 26.4 years (range 14-57 years). Soft tissue changes were assessed on lateral cephalometric radiographs. The mean maxillary hard tissue advancement and impaction ranged between 0.94 and 8.77 mm and -0.56 and 4.2 mm, respectively. The ranges of ratios demonstrated that from pronasale (0.24-0.35) to labrale superius (0.36-1.43), the soft tissues followed the underlying horizontal hard tissue movement increasingly more closely. Alar base cinch sutures and VY closures tended to increase these ratios. The soft tissue response was more variable vertically. None of the studies reported on maxillary incisor exposure change. More good quality prospective studies are needed. PMID:24103543

    The high content of inorganic species in water used to extract bitumen from the Alberta oil sands and in the groundwater below the oil sands is an increasing environmental concern. These water matrices require treatment before they can be reused or safely discharged. Desalination of the oil sands process-affected water (OSPW) and groundwater, or basal depressurization water (BDW), can be accomplished with deionization techniques such as electrodialysis (ED). In order to achieve the effective ED treatment, OSPW and BDW were pretreated with coagulation-flocculation-sedimentation to remove solid species and turbidity. We demonstrated that a conductivity range for industrial reuse of OSPW and BDW can be achieved with the ED treatment and showed the possibility of applying ED in the oil sands industry. A continuous ED system that reuses the diluate stream as a source for the concentrate stream was designed. The cost of a hypothetical ED water treatment plant in Fort McMurray, Alberta, was estimated to be C$10.71 per cubic meter of treated water. PMID:24355856

    Few reports have so far evaluated the maxillary stability after LeFort I osteotomy (L-1) for pitch correction. In the current study, the authors assessed the SN-PP (palatal plane) to evaluate the skeletal stability after osteotomy with clockwise or counter-clockwise rotation and investigated the effects of anterior nasal spine (ANS) and posterior nasal spine (PNS) movement on the stability of the SN-PP.The SN-PP and the positions of ANS, PNS, and point A were measured on lateral cephalograms before surgery (T1), immediately after surgery (T2), and more than 1 year after surgery (T3).All measured angle and points were stable in 4 cases of counter-clockwise rotation. In the 16 cases of clockwise rotation, T3-T2 of SN-PP, ANS, and point A was -2.05°, -2.56 mm, and -1.64 mm, when the SN-PP increased more than 4° after osteotomy. When the ANS moved downward more than 3 mm, the ANS and point A relapsed significantly by 2.75 and 2.31 mm, while the SN-PP relapsed 1.61° more than 1 year after surgery.When the SN-PP increased by more than 4° or the ANS moved downward by more than 3 mm, the authors suggest shifting the PNS upward instead of moving the ANS downward.

Ninon de Lenclos, célèbre courtisane du xviie siècle est l’un des rares exemples disponibles. Identifiée comme esprit fort dès le début xxe siècle, elle hérite de la construction historiographique du xviiie siècle qui en a fait une courtisane raisonnable qui a su s’entourer de grands esprits pour diffuser la sagesse de la Renaissance incrédule.

Pourtant la figure d’Aspasie, « la » maître d’éloquence et de philosophie de Périclès hante l’historiographie de Ninon de Lenclos, comme une fiction à la fois disponible et repoussée. Ninon de Lenclos a su pourtant tisser une sociabilité mixte où l’amitié, les plaisirs du corps et de l’esprit déniaisé étaient cultivés, mais c’est la difficulté à le penser qui a fait de Ninon un homme autre.After Nicolas-André Monsiau’s painting (1810 showing Ninon de Lenclos, amongst a group of male spectators, who listens to Molière as he reads his Tartuffe, we want to follow the historiographical construction of a woman as a « freethinker ».

  19. BP Canada energy company ethane cavern well fires Fort Saskatchewan, Alberta August/September 2001 : EUB Post-incident report April 2002

    International Nuclear Information System (INIS)

    A natural gas liquids (NGL) plant, located approximately 6 kilometres northeast of Fort Saskatchewan, Alberta, is operated by BP Canada Energy Company (BP). A pipeline is used to deliver the products to several locations in Alberta, eastern Canada, and the United States, and the products are stored on site. A two-inch line connecting two wellheads that service one of the storage caverns experienced the failure of an elbow on August 26, 2001. Subsequent investigations indicated that unusual transverse forging defects were the source of the elbow failure. Conventional testing methods would not have detected such defects. The consequence of this failure was the release of ethane product into the atmosphere. An ethane vapour plume was created, and it ignited upon contact with overhead power lines at the plant site. All access roads to and from the plant were immediately secured and there were no injuries to plant personnel. The emergency response plan developed by BP was activated and the facility was shut down. The public was not threatened in any way nor was their property even though the black smoke from the fire could be seen from far away. Well control operations were expedited through the cooperation of officials from the Alberta Energy and Utilities Board (EUB), Alberta Environment, local authorities and BP. Emissions of soot were the primary environmental impact and the provincial air quality guidelines were not exceeded. A review of the events indicate that local emergency response personnel reacted quickly to the situation in the appropriate manner although the expectations from the public were not met concerning early public notification. Equipment design changes have been effected to prevent reoccurrence. 4 figs

    In December 2004, the Colorado State University sodium lidar system at Fort Collins, Colorado (41 deg N, 105 deg W), conducted an approximately 80-hour continuous campaign for the simultaneous observations of mesopause region sodium density, temperature, and zonal and meridional winds. This data set reveals the significant inertia-gravity wave activities with a period of approximately 18 hours, which are strong in both wind components since UT day 338 (second day of the campaign), and weak in temperature and sodium density. The considerable variability of wave activities was observed with both wind amplitudes growing up to approximately 40 m/s at 95-100 km in day 339 and then decreasing dramatically in day 340. We also found that the sodium density wave perturbation is correlated in phase with temperature perturbation below 90 km, and approximately 180 deg out of phase above. Applying the linear wave theory, we estimated the wave horizontal propagation direction, horizontal wavelength, and apparent horizontal phase speed to be approximately 25 deg south of west, approximately 1800 +/- 150 km, and approximately 28 +/- 2 m/s, respectively of wave intrinsic period, intrinsic phase speed, and vertical wavelength were also estimated. While the onset of enhanced inertia-gravity wave amplitude in the night of 338 was observed to be in coincidence with short-period gravity wave breaking via convective instability, the decrease of inertia-gravity wave amplitude after noon of day 339 was also observed to coincide with the development of atmospheric dynamical instability layers with downward phase progression clearly correlated with the 18-hour inertia-gravity wave, suggesting likely breaking of this inertia-gravity wave via dynamical (shear) instability.

    Full Text Available The giant organs and enhanced concentrations of secondary metabolites realized by autopolyploidy are attractive for breeding the respective medicinal and agricultural plants and studying the genetic mechanisms. The traditional medicinal plant Chinese woad (Isatis indigotica Fort., 2n = 2x = 14 is now still largely used for the diseases caused by bacteria and viruses in China. In this study, its autopolyploids (3x, 4x were produced and characterized together with the 2x donor for their phenotype and transcriptomic alterations by using high-throughput RNA sequencing. With the increase of genome dosage, the giantism in cells and organs was obvious and the photosynthetic rate was higher. The 4x plants showed predominantly the normal meiotic chromosome pairing (bivalents and quadrivalents and equal segregation and then produced the majority of 4x progeny. The total 70136 All-unigenes were de novo assembled, and 56,482 (80.53% unigenes were annotated based on BLASTx searches of the public databases. From pair-wise comparisons between transcriptomic data of 2x, 3x, 4x plants, 1856 (2.65%(2x vs 4x, 693(0.98%(2x vs 3x, 1045(1.48%(3x vs 4x unigenes were detected to differentially expressed genes (DEGs, including both up- and down-regulated ones. These DEGs were mainly involved in cell growth (synthesis of expansin and pectin, cell wall organization, secondary metabolite biosynthesis, response to stress and photosynthetic pathways. The up-regulation of some DEGs for metabolic pathways of functional compounds in the induced autotetraploids substantiates the promising new type of this medicinal plant with the increased biomass and targeted metabolites.

    A study of the effects of storm runoff from urban areas on water quality at Fort Leavenworth, Kansas, was conducted from May 1994 through September 1996. The purpose of this report is to present information to assess the current (1994-96) conditions and possible methods for anticipating future water-quality effects from storm runoff and changes in land use. Three sampling sites were established to monitor streamflow and water quality from three watersheds draining the study area. Streamflow was monitored continuously, and water-quality samples were collected during low-flow (12 samples) and storm-runoff (21 samples) conditions to determine mean annual constituent loads. Constituent concentrations for the most part were smallest during low flow with the exception of major ions, dissolved solids, and some nutrients. Concentrations of suspended solids and total recoverable metals at all three sites were much larger in storm-runoff samples than in low-flow samples--typically an order of magnitude larger than low-flow concentrations. Mean low-flow nutrient concentrations were either larger than or smaller than storm-runoff concentrations depending on the watershed. Total chloroform and total tetrachloroethylene were the only two volatile organic compounds detected, and acid-base/neutral organic compounds were not detected in any of the samples collected. Eight pesticides were detected in low-flow samples, and 15 pesticides were detected in storm-runoff samples. The only mean concentrations of the selected constituents in this study that exceeded either the U.S. Environmental Protection Agency's Maximum Contaminant Level or the Secondary Maximum Contaminant Level were dissolved solids and total recoverable iron and manganese.

  3. Subsurface evaluation of the west parking lot and landfill 3 areas of Air Force Plant 4, Fort Worth, Texas, using two-dimensional direct-current resistivity profiling

    2002-01-01

    During September 1999, the U.S. Geological Survey made 10 two-dimensional direct-current resistivity profile surveys in the west parking lot and landfill 3 areas of Air Force Plant 4, Fort Worth, Texas, to identify subsurface areas of anomalously high or low resistivity that could indicate potential contamination, contaminant pathways, or anthropogenic structures. Six of the 10 surveys (transects) were in the west parking lot. Each of the inverted sections of these transects had anomalously high resistivities in the terrace alluvium/fill (the surficial subsurface layer) that probably were caused by highly resistive fill material. In addition, each of these transects had anomalously low resistivities in the Walnut Formation (a bedrock layer immediately beneath the alluvium/fill) that could have been caused by saturation of fractures within the Walnut Formation. A high-resistivity anomaly in the central part of the study area probably is associated with pea gravel fill used in construction of a French drain. Another high resistivity anomaly in the west parking lot, slightly southeast of the French drain, could be caused by dense nonaqueous-phase liquid in the Walnut Formation. The inverted sections of the four transects in the landfill 3 area tended to have slightly higher resistivities in both the alluvium/fill and the Walnut Formation than the transects in the west parking lot. The higher resistivities in the alluvium/fill could have been caused by drier conditions in grassy areas relative to conditions in the west parking lot. Higher resistivities in parts of the Walnut Formation also could be a function of drier conditions or variations in the lithology of the Walnut Formation. In addition to the 10 vertical sections, four horizontal sections at 2-meteraltitude intervals show generally increasing resistivity with decreasing altitude that most likely results from the increased influence of the Walnut Formation, which has a higher resistivity than the terrace

    The depositional architectures of deep-water turbiditic deposits are strongly influenced by seafloor topography. Slope gradient variations of less than one degree might be sufficient to change the distribution of sands significantly along the basin profile. Stratigraphic units of deep-water sandstones from the Fort Brown Fm. in the Laingsburg depocentre (Karoo Basin, South Africa) are an example of that. Regional mapping and stratigraphic correlation of Units C to F (Van der Merwe et al., 2014) show a change from sand-attached systems in Units C and D to sand-detached systems in Units E and F. The sand-attached systems show a continuity of sands from entrenched slope valleys to basin-floor lobe complexes, while in the sand-detached systems there are widespread sand bypass zones of approximately 10 to 30 km where almost no sand is deposited and erosive features are observed. This is interpreted to reflect the development of a stepped slope profile. Lobe deposits occur before and after the bypass region, but significant differences in depositional architecture are noticed between these lobe deposits. The intraslope lobes are characterized by an aggradational to compensational stacking pattern and a common occurrence of erosive features, while the basin floor lobes show a lateral compensating stacking pattern with less erosive features. In this study, process-based numerical modelling of turbidity currents are performed to test if a stepped slope to basin profile with subtle gradient changes similar to that interpreted for the Laingsburg depocentre during the deposition of Unit E are suitable to generate the sediment distribution pattern observed in the field. Through an iterative modelling workflow we aim to constrain the paleoslope gradient changes using the parameters constrained from outcrop. The study also investigates how flow parameters such as sediment concentration, flow velocity, flow thickness and Froude number behave as a function of different slope

  8. Modelisation de l'erosion hydrique en milieu semi-aride de forte energie de relief a partir de donnees de teledetection: Application a la Bolivie

    Science.gov (United States)

    Ouattara, Tidiane

    In this study, we propose a model of water erosion risks for such environments using remote sensing and morphometric data: MEH-SAFER (Modele d'Erosion Hydrique en milieu Semi-Aride de Forte Energie de Relief). MEH-SAFER is based on the Lamachere and Guillet model (MLG) (Burkina Faso) to the Lake Laka-Laka drainage basin (Bolivia). While preserving the same principle calculations of runoff potential, we have improved the acquisition method of the biophysical data in order to avoid errors related to topography and to the ground data. We have conceived a method based on multisource satellite images (RADARSAT-1, Landsat-7 and SPOT-4). We replaced the geomorphological graphic models used by Lamachere and Guillet with a topographic vulnerability map originating from the MVT (topographic vulnerability model). This, in turn, was derived from a DEM. Several combinations of multisource image and texture bands give classification accuracies greater than 80% for the land use classes. These include, among others, the combinations of entropy-ETM+2-ETM+4, correlation-ETM+2-ETM+4, homogeneity-ETM +2-ETM+4, mean-ETM+2-ETM +4, standard deviation-ETM+2-ETM+4, original radar image-ETM+2-ETM+4, dissimilarity-ETM +2-ETM+4, angular second moment-ETM+2-ETM +4, XS1-ETM+3-ETM+4 and XS2-ETM +3-ETM+4. In 83% of the basin, the potential runoff is superior to 0,50 on a maximum of 1. In the remaining 17% of the basin, the potential varies of 0 to 0,42, which is explained by the resistant hydrodynamical characteristics of the geoecological units. The results reported here reveal that in general the study area is not particularly vulnerable to erosion and that as a consequence the perceived rate of sedimentation is a natural consequence of the morphoclimatic conditions of the drainage basin. The main contribution of this study is the development of the MEH-SAFER. It includes several original ingredients including the numerical processing of multisource satellite data and morphometric topographical

    Within the North Dakota Little Missouri Badlands, a continuous succession of Cretaceous through lowermost Eocene age sediments exposes a nearly complete terrestrial Paleocene record. Using the K-T boundary as the basal datum, a ca.180 meter composite section of the lowermost Fort Union Formation has been constructed. Paleomagnetic samples that have been analyzed from this section demonstrate a series of geomagnetic reversals that can be correlated from C29r through C28n of the Geomagnetic Polarity Time Scale. Based on these paleomagnetic data, the mean sedimentation rates during the interval from the K-T boundary to the top of 28r are estimated to be ca. 100 m/Myr. These data have allowed us to calibrate the two tongues of the marine Cannonball Member to within C29n and C28r respectively, and identify a major change in the composition and dominant taxa in the megafloral record near the end of C28r. One potential implication of this result, pending further data analysis and correlations to fossil-bearing sections, is the temporal restriction of the Puercan-Torrejonian 1 North American Land Mammal "Ages" (NALMAs) by nearly a factor of two relative to previous estimates (i.e. from ca. 2 Myr to ca. 1 Myr). This would in turn suggest that post-extinction mammal speciation occurred twice as fast as previously supposed. The ultimate aim of this research is to develop a high-precision chronostratigraphic reference section for the Paleocene of the Rocky Mountain Region of North America using lithostratigraphy, magnetostratigraphy, pollen and megafloral biostratigraphy, chemostratigraphy, and chronostratigraphy, that can be used to determine the temporal extent of floral and faunal radiation after the Cretaceous-Paleogene extinctions, and to assess patterns of floral and faunal diversity and composition in response to numerous climatic changes. Furthermore, we hope to use this chronostratigraphic section for comparisons with contemporaneous sections worldwide, which will

    The NAHB Research Center partnered with production builder Winchester/Camberley Homes to build a DOE Building America New Construction Test House (NCTH). This single family, detached house, located in the mixed-humid climate zone of Silver Spring, MD, was completed in June 2011. The primary goal for this house was to improve energy efficiency by 30% over the Building America B10 benchmark by developing and implementing an optimized energy solutions package design that could be cost effectively and reliably constructed on a production basis using quality management practices. The intent of this report is to outline the features of this house, discuss the implementation of the energy efficient design, and report on short-term testing results. During the interactive design process of this project, numerous iterations of the framing, air sealing, insulation, and space conditioning systems were evaluated for energy performance, cost, and practical implementation. The final design featured numerous advanced framing techniques, high levels of insulation, and the HVAC system entirely within conditioned space. Short-term testing confirmed a very tight thermal envelope and efficient and effective heating and cooling. In addition, relevant heating, cooling, humidity, energy, and wall cavity moisture data will be collected and presented in a future long-term report.

    Full Text Available A botanical inventory of the Mandena littoral forest, completed in 1991 as part of an environmental impact assessment study for a titanium oxide mining project being developed by QMM / Rio Tinto in the Tolagnaro (Fort Dauphin region of southeastern Madagascar, identified 29 plant taxa as priorities for conservation, including 16 known only from the proposed mining path (Priority 1 and 13 restricted to the exploration zone (Priority 2. A re - evaluation in 2001 added 11 taxa from Mandena (the first of three sites targeted for mining, to be followed later by Petriky and then Sainte Luce and removed 13 others, leaving a total of 27 taxa, five classified as Priority 1 and 22 as Priority 2. Using currently available data, we have removed four additional taxa from the list (three because populations were found outside the Tolagnaro area and one because it’s earlier inclusion on the list had been in error and transferred four others from Priority 1 to Priority 2 as populations had been located within one or more of the newly - established conservation zones at Sainte Luce (747 ha, Mandena (230 ha and Petriky (125 ha.

    This report is one of many supporting documents used by the Nuclear Regulatory commission in the preparation of the Nuclear Energy Center Site Survey (NECSS) mandated by Congress. While the overall study focuses on the feasibility and practicability of nuclear energy centers (NECs), this report is directed towards choosing a suitable surrogate site in the upper St. Lawrence region of New York State, assessing the probable impacts associated with construction and operation of the NEC, and comparing these impacts with those associated with small dispersed nuclear power stations. The upper St. Lawrence region is surveyed to identify a specific site that might be suitable for a surrogate NEC. Several assumptions about the basic design of an NEC are delineated, and a general overview of the characteristics of the region is given. The Fort Drum Military Reservation is chosen as a suitable surrogate site. Fort Drum and the surrounding area are described in terms of land use and population patterns, terrestrial and aquatic ecology, water use and quality, meteorology, institutional framework, and socioeconomic structure. The impacts associated with NEC development are assessed. Then the impacts associated with smaller dispersed nuclear power stations located throughout New York State are assessed and compared with the impacts associated with the NEC. Finally, the impacts due to development of the transmission line networks associated with the NEC and with the dispersed power stations are assessed and compared.

    The overall objective of this project is the continued development, installation, and testing of continuous water sampling and analysis technologies for application to on-site monitoring of groundwater treatment systems and remediation sites. In a previous project, an on-line analytical system (OLAS) for multistream water sampling was installed at the Fort Ord Operable Unit 2 Groundwater Treatment System, with the objective of developing a simplified analytical method for detection of Compounds of Concern at that plant, and continuous sampling of up to twelve locations in the treatment system, from raw influent waters to treated effluent. Earlier implementations of the water sampling and processing system (Analytical Sampling and Analysis Platform, A A+RT, Milpitas, CA) depended on off-line integrators that produced paper plots of chromatograms, and sent summary tables to a host computer for archiving. We developed a basic LabVIEW (National Instruments, Inc., Austin, TX) based gas chromatography control and data acquisition system that was the foundation for further development and integration with the ASAP system. Advantages of this integration include electronic archiving of all raw chromatographic data, and a flexible programming environment to support development of improved ASAP operation and automated reporting. The initial goals of integrating the preexisting LabVIEW chromatography control system with the ASAP, and demonstration of a simplified, site-specific analytical method were successfully achieved. However, although the principal objective of this system was assembly of an analytical system that would allow plant operators an up-to-the-minute view of the plant's performance, several obstacles remained. Data reduction with the base LabVIEW system was limited to peak detection and simple tabular output, patterned after commercial chromatography integrators, with compound retention times and peak areas.

    Information and measured data from the intial Fort St. Vrain (FSV) high temperature gas reactor core is used to develop a benchmark configuration to validate computational methods for analysis of a full-core, commercial HTR configuration. Large uncertainties in the geometry and composition data for the FSV fuel and core are identified, including: (1) the relative numbers of fuel particles for the four particle types, (2) the distribution of fuel kernel diameters for the four particle types, (3) the Th:U ratio in the initial FSV core, (4) and the buffer thickness for the fissile and fertile particles. Sensitivity studies were performed to assess each of these uncertainties. A number of methods were developed to assist in these studies, including: (1) the automation of MCNP5 input files for FSV using Python scripts, (2) a simple method to verify isotopic loadings in MCNP5 input files, (3) an automated procedure to conduct a coupled MCNP5-RELAP5 analysis for a full-core FSV configuration with thermal-hydraulic feedback, and (4) a methodology for sampling kernel diameters from arbitrary power law and Gaussian PDFs that preserved fuel loading and packing factor constraints. A reference FSV fuel configuration was developed based on having a single diameter kernel for each of the four particle types, preserving known uranium and thorium loadings and packing factor (58%). Three fuel models were developed, based on representing the fuel as a mixture of kernels with two diameters, four diameters, or a continuous range of diameters. The fuel particles were put into a fuel compact using either a lattice-bsed approach or a stochastic packing methodology from RPI, and simulated with MCNP5. The results of the sensitivity studies indicated that the uncertainties in the relative numbers and sizes of fissile and fertile kernels were not important nor were the distributions of kernel diameters within their diameter ranges. The uncertainty in the Th:U ratio in the intial FSV core was

    Ground-water and sediment contamination by petroleum hydrocarbons resulting from leaks and overfills was detected during tank removal activities at three former underground storage tank locations at Fort Jackson, near Columbia, South Carolina. Investigations were initiated to assess the effect of contamination to the surficial aquifer at Sites 1062, 2438, and 2444. These investigations involved the installation of permanent monitoring wells and the collection and analysis of sediment and ground-water samples at the three sites. Water-level data were collected at all sites to determine hydraulic gradients and the direction of ground-water flow. In addition, aquifer tests were made at Site 1062 to determine the hydraulic conductivity of the surficial aquifer at that site. Sediment borings were made at the three sites to collect subsurface-sediment samples for lithologic description and laboratory analyses, and for the installation of ground-water monitoring wells. Laboratory analyses of sediment samples collected from boreholes at Site 1062 indicated elevated concentrations of petroleum hydrocarbons at three locations. Total Petroleum Hydrocarbons - Diesel Range Organics were detected at one borehole at a concentration of 388,000 micrograms per kilogram. Total benzene, toluene, ethylbenzene, and xylene concentrations in sediment from the site ranged from less than 350 to over 100,000 micrograms per kilogram. Total lead was detected at concentrations ranging from 2,900 to 5,900 micrograms per kilogram. Petroleum hydrocarbons were detected at Site 2438 in one borehole at a trace concentration of 112 micrograms per kilogram of para- and meta-xylenes. No concentrations exceeding the detection limits were reported for petroleum hydrocarbons in sediment samples collected from Site 2444; however, total lead was detected in sediment samples from two boreholes, each at concentrations of 600 micrograms per kilogram. Ground-water samples were collected from each site for

    Uncertainties in emissions estimates are known to be one of the primary sources of uncertainty in calculating concentrations and subsequent exposure estimates. Despite continued improvement in the accuracy of emissions downscaling, the quantification of uncertainties is necessary in order to generate a representative emissions product. Bayesian data assimilation is a promising approach to uncertainty estimation when used to calibrate model results with measurement data. This study discusses an emissions inventory and concentration estimates for carbon monoxide (CO), fine particle (PM2.5) black carbon, and nitrogen oxides (NOx) for the city of Fort Collins, Colorado. The development of a Bayesian framework for updating estimates of emissions and concentrations in multiple stages, using measurement data, is also presented. The emissions inventory was constructed using the 2008 National Emissions Inventory (NEI). The spatial and temporal allocation methods from the Emission Modeling Clearinghouse data set are used to downscale the NEI data from annual and county-level resolution for point, nonpoint, and nonroad sources. Onroad mobile source emissions were estimated by combining a bottom-up emissions calculation approach (using emission factors and activities) for large roadway links within Fort Collins with a top-down spatial allocation approach for other roadways. Vehicle activity data for road links were obtained from local 2009 travel demand model results and automatic traffic recorder (ATR) data. The CALPUFF Gaussian puff dispersion model was used to estimate air pollutant concentrations. Hourly, 1.33 km x 1.33 km MM5 meteorological data was used to capture temporal variability in transport. Distributions of concentrations are obtained for spatial locations and time spans using a Monte Carlo sampling approach. Data for ensemble members are sampled from distributions defined from the emissions inventory and meteorological data. Modeled concentrations of CO, PM2

  20. Experimental sediment exchanges between natural and constructed wetlands on oil sands leases, near Fort McMurray, Alberta : a look at the relationship between sediment treatments and benthic macroinvertebrates colonizers

    International Nuclear Information System (INIS)

    Oil sand mining activity has been ongoing in the Fort McMurray area since the 1960s, affecting more than 1400 sq. km. of land that has required, and will continue to require, land reclamation. This study examined the feasibility of sequestering mining by-products, a method that has received much attention in recent years. In particular, it examined the suitability of using the mining by-product consolidated tailings as sediment for constructed wetlands. The study isolates the effect of tailings associated water from the effect of consolidated tailings sediment on benthic macroinvertebrate population health. Sediments from reference and opportunistic wetlands were transplanted with sediment from a constructed wetland layered with 4 metres of consolidated tailings. The effects of macrophyte presence in these plots will be examined and contrasted with macroinvertebrates to determine a possible relationship
