  20. Outage project productivity improvement of TVA fossil

    SciTech Connect (OSTI)

    Picard, H.E.; Seay, C.R. Jr.

    1996-10-01

    Competition in the utility industry forces management to look closely at the cost effectiveness of power plant outage projects. At TVA Fossil and Hydro Power, innovative work measurement is proving effective as a project management tool to do more with less. Labor-hours to complete outage work scopes are reduced by some 20 to 30%, not by working harder or sacrificing safety, or quality, but by working and managing smarter. Fossil power plant outages and shutdowns are costly. They are labor-intensive construction projects, often with expanding work scope, and executed on a fast track. Outage work is inherently complex and dynamic, and often unpredictable. Many activities and tasks must be integrated, coordinated and completed safely and efficiently by multiple crafts and work groups. As a result, numerous productivity factors can influence the cost and schedule of outage completion. This provides owners, contractors and labor with unique opportunities for competitive advantage--by making radical changes in how they manage labor-hours and time.

  2. Concrete growth problems and remedial measures at TVA projects

    SciTech Connect (OSTI)

    Hammer, J.J.

    1984-01-01

    Most concrete structures are designed and detailed to provide for a volume decrease without excessive cracking. Occasionally, however, a concrete structure exhibits a long-term increase in volume termed concrete growth. Concrete growth may result from a variety of reactions, such as the hydration of unstable oxides included in the concrete mix, or the oxidation of minerals or from an outside attack of sulfates. The most important reaction creating concrete growth is that between minor alkali hydroxides from cement and the concrete aggregates. Two distinctly different harmful reactions have been recognized: the alkali-silicate and alkali-carbonate reactions. Concrete deteriorating from an alkali-aggregate reaction, regardless of the type, develops an obvious network of cracks called pattern or map cracking. These alkali-aggregate reactions and their accompanying concrete growth have presented numerous problems at TVA's Fontana Dam, Chickamauga Dam and lock, and Hiwassee Dam. Much has been learned about alkali-aggregate reaction since 1940. Most harmful reactions can now be prevented in proposed structures by interpreting the results of standard test methods. It is not possible, however, in existing structures to determine how far the growth phenomenon has progressed, how long the effects will have to be dealt with, or what the future effects will be. A program of close surveillance and monitoring is maintained at these projects, and problems are dealt with as they arise.

  3. Preliminary Feasibility Assessment of Geologic Carbon Sequestration Potential for TVA's John Sevier and Kingston Power Plants

    SciTech Connect (OSTI)

    Smith, Ellen D; Saulsbury, Bo

    2008-03-01

    This is a preliminary assessment of the potential for geologic carbon sequestration for the Tennessee Valley Authority's (TVA) John Sevier and Kingston power plants. The purpose of this assessment is to make a 'first cut' determination of whether there is sufficient potential for geologic carbon sequestration within 200 miles of the plants for TVA and Oak Ridge National Laboratory (ORNL) to proceed with a joint proposal for a larger project with a strong carbon management element. This assessment does not consider alternative technologies for carbon capture, but assumes the existence of a segregated CO{sub 2} stream suitable for sequestration.

  4. Finite element analysis of three TVA dams with alkali-aggregate reaction

    SciTech Connect (OSTI)

    Grenoble, B.A.; Meisenheimer, J.K.; Wagner, C.D.; Newell, V.A.

    1995-12-31

    Three large Tennessee Valley Authority (TVA) dams are currently experiencing problems caused by alkali-aggregate reaction (AAR). Since the fall of 1990, engineers in Stone & Webster`s Denver, Colorado office have been working with TVA to evaluate how AAR is affecting the dams and to identify measures for controlling the adverse effects of the concrete growth. This paper provides an overview of how finite element analysis is being used to understand the affects of AAR on these structures and to evaluate alternatives for minimizing the adverse effects of the concrete growth. Work on Hiwassee Dam is essentially complete, while that on the Chickamauga and Fontana Projects is still in progress. Consequently, this paper will focus primarily on Hiwassee Dam. The ongoing work on the other two projects will only be discussed briefly.

Technical description of the design is given in this volume.

  6. Automatic UT inspection of economizer at TVA`s Paradise plant

    SciTech Connect (OSTI)

    Brophy, J.W.; Chang, P.

    1995-12-31

    In March 1995, Tennessee Valley Authority (TVA) and Southwest Research Institute (SwRi) conducted testing of a multi-element ultrasonic probe designed to inspect economizer tubing in the Paradise power plant during the spring outage. This evaluation was to determine general loss of wall thickness due to erosion/corrosion and preferential inside diameter (ID) corrosion at butt welds in straight sections of the tube. The erosion/corrosion wall loss occurs during service while the butt weld corrosion occurs out-of-service when water collects in the weld groove during outages and results in localized pitting in the weld groove. The ultrasonic (UT) probe was designed to acquire thickness measurements from the ID of the economizer tubes and to be accurate, very rapid UT inspection. To attain a high rate of speed inside the tubes, an eight-element circular array of transducers were designed into the probe head. Thickness data and location data are collected automatically by a portable computer.

  8. Feasibility studies to rehabilitate TVA`s Chickamauga Navigation Facility due to the effects of concrete growth

    SciTech Connect (OSTI)

    Niznik, J.A.; Conner, G.G.

    1995-12-31

    Chickamauga Dam is a multi-purpose project constructed by the Tennessee Valley Authority (TVA) in the early 1940s. Shortly after construction it was evident there was an alkali-aggregate reaction taking place in the concrete structures. This reaction resulted in a phenomenon of concrete growth; i.e., unchecked expansion of the concrete which causes high stresses, cracking and movement of concrete structures, and undesirable side effects. This problem has increased in severity resulting in increased concerns about structural integrity of the dam structures and long term outages to navigation.

  9. Metal wastage analysis of carbon steel tubes from TVA 20 MW AFBC (atmospheric fluidized-bed combustion)

    SciTech Connect (OSTI)

    Natesan, K.

    1987-11-01

    Evaporator tubes of carbon steel material, obtained from the TVA 20 MW AFBC test facility, were examined for deposit formation and metal wastage. Three different regions of the tube sections were analyzed using electron diffraction and several electron-optical techniques. The results showed that excessive metal wastage in one of the locations can be attributed to erosive wear of chlorine impregnated iron oxide scales. The results also showed that corrosion accelerating elements such as Cl, S, and K act independent of each other on the carbon steel evaporator tubes and it is imperative to characterize the local environment in the vicinity of the tube banks for understanding the complex deposition/corrosion phenomena that occur in FBC systems. 2 refs., 11 figs., 1 tab.

  12. Analysis of organizational options for the uranium enrichment enterprise in relation to asset divesture. [BPA; TVA; SYNFUELS; CONRAIL; British TELECOM; COMSTAT

    SciTech Connect (OSTI)

    Harrer, B.J.; Hattrup, M.P.; Dase, J.E.; Nicholls, A.K.

    1986-08-01

    This report presents a comparison of the characteristics of some prominent examples of independent government corporations and agencies with respect to the Department of Energy's (DOE) uranium enrichment enterprise. The six examples studied were: the Bonneville Power Administration (BPA); the Tennessee Valley Authority (TVA); the Synthetic Fuels Corporation (SYNFUELS); the Consolidated Rail Corporation (CONRAIL); the British Telecommunications Corporation (British TELECOM); and the Communications Satellite Organization (COMSAT), in order of decreasing levels of government ownership and control. They range from BPA, which is organized as an agency within DOE, to COMSAT, which is privately owned and free from almost all regulations common to government agencies. Differences in the degree of government involvement in these corporations and in many other characteristics serve to illustrate that there are no accepted standards for defining the characteristics of government corporations. Thus, historical precedent indicates considerable flexibility would be available in the development of enabling legislation to reorganize the enrichment enterprise as a government corporation or independent government agency.

    1984-01-01

    It was found that lead-acid batteries, because of low specific energy density and life, are marginal for eV use. However, with the established lead-acid industry, they may be more economical for limited future eV applications. The NiFe battery provides sufficient energy density and range for many eV applications and can withstand abusive treatment. With its longer life, this system is attractive for commercial eV applications. It is also anticipated that NiZn, NiCd, and ZnCl systems may also show promise for the future.

  15. Lessons learned from reheater replacements TVA Gallatin Fossil Plant units 1 and 2

    SciTech Connect (OSTI)

    Chang, P.S.; Stangarone, R.J.

    1996-07-01

    Gallatin Units 1 and 2 have experienced a long history of problems in the reheat front inlet platens and front outlet pendants. Cracks were discovered at lug welds on the reheat inlet platen assemblies after six years of operation. During the next ten years cracking at lugs continued to be a problem in both the inlet platen and front outlet assemblies. Solutions included changing tube material and spacing, and redesigning lugs. None of the solutions were successful. In 1980, a fuel switch to washed coal was made to reduce boiler slagging. Within two years of the fuel change, liquid phase corrosion began to attack the tubes. The corrosion became severe and elements were replaced at seven year intervals. During this time, EPRI sought utilities with boilers experiencing liquid phase corrosion to test new corrosion resistant materials. Gallatin Unit 2 was selected as one of the test units. Probes containing a number of different alloys were inserted into the furnace and subjected to the corrosion attacks. After a five year study, HR3C was selected as the alloy from which to build a complete set of elements for further testing. Reheat assemblies were manufactured from HR3C and installed in Unit 2 and Unit 1 Shortly after Unit 1 returned to service, swages between the front pendant and inlet platen elements failed by brittle fracture due to the cold swaging operation used in fabrication. Cracks were discovered after two years of operation at the tube to lug welds and the new elements were experiencing the same liquid phase corrosion as in the past. The attempt to resolve the liquid phase corrosion problem in Gallatin Units 1 and 2 pendant reheater revealed that past replacements did not address the root cause of the problems. HR3C is a relatively brittle material and manufacturers used traditional methods to design and fabricate the elements. Inadequate fabrication and erection procedures have led to several in-service problems not associated with liquid phase corrosion.

    SciTech Connect (OSTI)

    Badger, P C; Pile, R S

    1980-01-01

    This contract has provided for the documentation of the feasibility of fuel alcohol production with small onfarm facilities, and for the design and construction of an efficient and easily constructed production facility. A feasibility study and a preliminary design report have been prepared. A prototype facility has been designed and constructed with a design production rate of 10 gallons per hour of 190-proof ethanol. The components of the facility are readily available through normal equipment supply channels or can be primarily owner-constructed. Energy efficiency was also of prime consideration in the design, and heat recovery equipment is included where practical. A renewable fuel boiler is used for process heat. Applicable safety standards and environmental requirements were also incorporated into the design. Other project activities included modification of a pickup truck to use the hydrous alcohol produced, evaluation of vacuum distillation for onfarm units, and development of a computer program to allow detailed economic analyses of fuel alcohol production. Efforts were also initiated to evaluate nongrain feedstocks, develop a preliminary design for a low-cost wood-fired boiler, and evaluate packed distillation columns constructed of plastic pipe.

    2013-07-01

    In April 2001 the Department of Energy (DOE) and the Tennessee Valley Authority (TVA) signed an Interagency Agreement to transfer approximately 33 MT of off-specification (off-spec) highly enriched uranium (HEU) from DOE to TVA for conversion to commercial reactor fuel. Since that time additional surplus off-spec HEU material has been added to the program, making the total approximately 46 MT off-spec HEU. The disposition path for approximately half (23 MT) of this 46 MT of surplus HEU material, was down blending through the H-canyon facility at the Savannah River Site (SRS). The HEU is purified through the H-canyon processes, and then blended with natural uranium (NU) to form low enriched uranium (LEU) solution with a 4.95% U-235 isotopic content. This material was then transported to a TVA subcontractor who converted the solution to uranium oxide and then fabricated into commercial light water reactor (LWR) fuel. This fuel is now powering TVA reactors and supplying electricity to approximately 1 million households in the TVA region. There is still in excess of approximately 10 to 14 MT of off-spec HEU throughout the DOE complex or future foreign and domestic research reactor returns that could be recovered and down blended for use in either currently designed light water reactors, ?5% enriched LEU, or be made available for use in subsequent advanced 'fast' reactor fuel designs, ?19% LEU.

    Fehring, J.P.

    1990-10-01

    Dissolved oxygen (DO) concentrations are often used to define the water quality of a stream or reservoir. In the Tennessee Valley, there is a commonly held belief that water quality in general, and DO in particular, is declining in TVA reservoirs. In 1980, TVA conducted a study of DO trends in the tailraces of Tennessee River Dams and found a downward trend in most reservoirs, with the greatest decrease in the downstream reservoirs. This report examines a change in sampling procedures which may have contributed to the perception of declining DO. 6 refs., 3 figs., 10 tabs.

    1992-09-29

    The Rhinehart Tire Fire Dump site is located in a 22-acre drainage area of a sparsely populated rural area in western Frederick County, Virginia. Surface water runoff flows into a north-south tributary that discharges to Hogue Creek, which is 4,000 feet downstream. Bedrock is noted to be highly fractured, and the ground water flow in the overburden aquifer is toward Massey Run. From 1972 to 1983, the site owner conducted a tire disposal operation, which consisted of transporting discarded tires from various locations and storing them on a 5-acre wooded slope behind his home. An estimated 5 to 7 million tires that had been accumulated caught on fire in October 1983 and burned until July 1984. As a result of the fire, a free-flowing oily-tar, which contained anthracene, benzene, cadmium, chromium, ethylbenzene, napthalene, nickel, pyrene, toluene, and zinc, began to seep out of the tire pile into Massey Run and on to Hogue Creek.

    Protection and enhancement of water quality is essential for attaining the full complement of beneficial uses of TVA reservoirs. The responsibility for improving and protecting TVA reservoir water quality is shared by various federal, state, and local agencies, as well as the thousands of corporations and property owners whose individual decisions affect water quality. TVA's role in this shared responsibility includes collecting and evaluating water resources data, disseminating water resources information, and acting as a catalyst to bring together agencies and individuals that have a responsibility or vested interest in correcting problems that have been identified. This report is one in a series of status reports that will be prepared for each of TVA's reservoirs. The purpose of this status report is to provide an up-to-date overview of the characteristics and conditions of Wheeler Reservoir, including: reservoir purposes and operation; physical characteristics of the reservoir and the watershed; water quality conditions: aquatic biological conditions: designated, actual, and potential uses of the reservoir and impairments of those uses; ongoing or planned reservoir management activities. Information and data presented here are form the most recent reports, publications, and original data available. 21 refs., 8 figs., 29 tabs.

    The Department of Energy (DOE) and Tennessee Valley Authority (TVA) entered into an Interagency Agreement to transfer approximately 40 metric tons of highly enriched uranium (HEU) to TVA for conversion to fuel for the Browns Ferry Nuclear Power Plant. Savannah River Site (SRS) inventories included a significant amount of this material, which resulted from processing spent fuel and surplus materials. The HEU is blended with natural uranium (NU) to low enriched uranium (LEU) with a 4.95% 235U isotopic content and shipped as solution to the TVA vendor. The HEU Blend Down Project provided the upgrades needed to achieve the product throughput and purity required and provided loading facilities. The first blending to low enriched uranium (LEU) took place in March 2003 with the initial shipment to the TVA vendor in July 2003. The SRS Shipments have continued on a regular schedule without any major issues for the past 5 years and are due to complete in September 2008. The HEU Blend program is now looking to continue its success by dispositioning an additional approximately 21 MTU of HEU material as part of the SRS Enriched Uranium Disposition Project.

    The Rhinehart (aka Winchester) Tire Fire Site is located near the town of Winchester in Frederick County, Virginia. In October 1983, a fire was started in the tires disposed of on the site. Hot oil was released from the melting and pyrolysis of the tires. This oil made its way to Massey Run, a nearby surface water body. The fire was brought under control within a few days, but continued to smolder for six months. The migration of the oil and the residue from the fire have contaminated the site. The site is of potential public health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse human health effects. Human exposure to heavy metals, polynuclear aromatic hydrocarbons and volatile organic compounds may occur via ingestion, inhalation and dermal absorption of contaminated groundwater, surface water, sediments and soils.

    The objective of the TVA Aquatic Plant Management Program is to support in an environmentally and economically responsible manner, the balanced multiple uses of the water resource of the Tennessee Valley. This is accomplished by following an integrated approach to prevent introduction and spread of noxious species, documenting occurrence and spread of existing species, and suppressing or eliminating problems in designated high use areas. It is not the TVA objective, nor is it biologically feasible and prudent to eliminate all aquatic vegetation. Aerial photography, helicopter reconnaissance, and field surveys are used to assess distributions and abundance of various aquatic macrophytes. Water level fluctuations are supplemented by herbicide applications to control undesirable vegetation. Investigations are conducted to evaluate water level fluctuation schemes, as well as biological, mechanical, and alternative chemical control techniques which offer potential for more environmentally compatible and cost-effective management operations.

    Top address a growing national problem with generation of wastes and by-products, TVA has been involved for several years with developing and commercializing environmentally responsible practices for eliminating, minimizing, or utilizing various wastes/by-products. In many cases, reducing waste generation is impractical, but the wastes/by-products can be converted into other environmentally sound products. In some instances, conversion of safe, value-added agricultural products in the best or only practical alternative. TVA is currently involved with a diversity of projects converting wastes/by-products into safe, economical, and agriculturally beneficial products. Environmental improvement projects have involved poultry litter, cellulosic wastes, used battery acid, ammonium sulfate fines, lead smelting effluents, deep-welled sulfuric acid/ammonium bisulfate solutions, wood ash, waste magnesium ammonium sulfate slurry from recording tape production, and ammunition plant waste sodium nitrate/ammonium nitrate streams.

    Three of The Tennessee Valley Authority (TVA) major hydroelectric projects are experiencing alkali-aggregate reaction (AAR), These projects include Fontana Dam and Powerhouse, Hiwassee Dam and Powerhouse, and Chickamauga Lock, Dam and Powerhouse, All of these dams are considered {open_quotes}high hazard,{close_quotes} causing significant economic losses from loss of power, replacement of the dam and generation facilities, and loss of life should they fail. This paper presents an overview of the descriptions of each of these projects, including construction and original instrumentation installed in the structure during construction, All of these projects are now 50 to 60 years old and are experiencing problems in one or more locations due to AAR with no indication of any slowing of the concrete growth process, Concrete problems at these projects came as no surprise. Cracks were noted within 5 years of construction, and by 1980 some of these cracks were 1/2 inch in width. continuous monitoring of these projects has always been a priority. This paper will discuss how the growth from AAR has affected each structure, which structures have been affected most, and why. It will discuss how TVA has managed AAR at these projects in the past and how TVA is changing from a reactive to a pro-active approach in its response to AAR.

    Suspected water quality contamination in Watts Bar Reservoir as a result of activities in past decades at the Department of Energy`s (DOE) Oak Ridge facility is of public concern. DOE, the Tennessee Valley Authority (TVA), the State of Tennessee, and other agencies and officials have received many inquiries from the public in recent years concerning this suspected pollution, especially how this potential contamination may affect the health and safety of those persons who use beaches in the area for swimming or other water-body-contact sports. As a result of these concerns, TVA conducted a study in May and June 1991 to obtain data on potential contaminants of concern in the water and sediment of Watts Bar Reservoir. TVA collected water and sediment samples at a total of 29 sites, including 18 recreation areas and 11 water intake locations, located throughout Norris, Melton Hill, and Watts Bar Reservoirs. The samples were analyzed for radionuclides, metals, and organic compounds which could pose a threat to human health.

    In January of 1992 a team was put together to begin the process of assessing the industrial waste needs of the Tennessee Valley. The team consisted of representatives from the various TVA Resource Group organizations. This initial team recommended as a starting point in the process a two-phase market research effort. A second team was then commissioned to conduct the first phase of this market research effort. The first phase of that marketing effort is now complete. This report contains an analysis of the data obtained through interviews of more than 168 individuals representing a similar number of organizations. A total of 37 TVA Resource Group employees were involved in the contact process from various organizations. In addition, the appendices provide summaries of the data used in designing the process and the reports of the Contact Coordinators (who were responsible for a series of visits). As a result of the data analysis, the Review Team makes the following recommendations: 1. Publish this report and distribute to the new management within TVA Resource Group as well as to all those participating as contacts, visitors, and contact coordinators. 2. The Resource Group management team, or management teams within each of the respective organizations within Resource Group, appoint Phase 2 assessement teams for as many of the problem areas listed in Table III as seem appropriate. We further recommend that, where possible, cross-organizational teams be used to examine individual problem areas. 3. Make this report available within Generating and Customer Groups, especially to the Customer Service Centers. 4. Establish a process to continue follow up with each of the contacts made in this assessment.

    For this research, extensive site-specific biological and environmental data were collected to support an evaluation of risks to the fish community in Watts Bar Reservoir from residual ash from the December 2008 Tennessee Valley Authority (TVA) Kingston ash release. This paper describes the approach used and results of the risk assessment for the fish community, which consists of multiple measurement endpoints (measures of exposure and effects) for fish. The lines of evidence included 1) comparing postspill annual fish community assessments with nearby prespill data and data from other TVA reservoirs, 2) evaluating possible effects of exposures of fish eggs andmore » larval fish to ash in controlled laboratory toxicity tests, 3) evaluating reproductive competence of field-exposed fish, 4) assessing individual fish health through physical examination, histopathology, and blood chemistry, 5) comparing fish tissue concentrations with literature-based critical body residues, and 6) comparing concentrations of ash-related contaminants in surface waters with US Environmental Protection Agency's (USEPA) Ambient Water Quality Standards for Fish and Aquatic Life. These measurement endpoints were treated as independent lines of evidence that were integrated into an overall weight-of-evidence estimate of risk to the fish community. Collectively, the data and analysis presented here indicate that ash and ash-related constituents pose negligible risks to the fish communities in Watts Bar Reservoir. This conclusion contradicts the predictions by some researchers immediately following the ash release of devastating effects on the aquatic ecology of Watts Bar Reservoir. The information presented in this article reaffirms the wisdom of carefully evaluating the evidence before predicting probable ecological effects of a major event such as the TVA Kingston ash release.

    Unlike siting new retail stores, utility companies face unique barriers to expanding their markets. Other than by merger and acquisition, utility companies can only expand into new markets by adding new transmission and/or pipelines to existing facilities. This situation lends itself to the use of corridor target marketing along the leading edge of existing markets to determine the best potential for expansion. This paper will detail how the Tennessee Valley Authority (TVA) utilized TARGETMASTER, a customized geographic information system (GIS), to locate and assess the potential to directly serve electrical power to commercial and industrial customers along a corridor.

    The overall population stands at 48 mines operating 53 longwalls. CONSOL Energy remains the leading US longwall operator with 12 installations. With the acquisition of the Andalex properties in Utah, Robert E Murray now owns eight longwall mines followed by Arch Coal (5) and Massey Energy (4). West Virginia remains the leading longwall mining state with 14 faces in 2005, followed by Pennsylvania (8), Alabama (6), Utah (6) and Colorado (5). A detailed table gives for each longwall installation, the ownership, seam height, cutting height, panel width and length, overburden, number of gate entries, depth of cut, model of equipment used (shearer, haulage system, roof support, face conveyor, stage loader, crusher, electrical controls and voltage to face). The most striking difference between the 2007 US Longwall Census and past reports carried out by Coal Age is the increased number of longwall operators that believe they have the most productive operation. Several operators have purchased or intend to purchase new equipment or upgrade the technology of the faces. Longwall mining in the US has reached a balanced state. 1 photo., 1 tab.

    Energy curves for the ground state and the first seven excited states of ArH have been calculated using the multiconfiguration valence bond (MCVB) method. Important features of the excited curves include two distinct avoided crossings between the lowest Ar*H and the highest ArH* potential energy curves. Using these curves we have made a theoretical analysis of quenching of metastable Ar by collision with H at room temperature. Application of the Massey criterion indicates that the separation of the potential curves in the region of the crossing and the acceleration produced by the fall of the reactant channel potential curve from its asymptotic level combine to produce a relatively high probability for curve switching. A more quantitative estimate of the curve switching probability is given with the Landau--Zener formula and leads to a theoretical value of the quenching rate approximately ten times the experimental. In light of the many approximations involved this qualitative agreement is satisfactory and provides a rationale to explain the anomalously high rate constant for the quenching reaction. Structural features of the interacting potential curves are discussed in terms of the diabatic states involved.

    The TVA 20-MW AFBC Pilot Plant located near Paducah, Kentucky began operations in March 1982, and it operated with the same in-bed evaporator tubes (tube bundle B1) for {approximately}13,625 h through the end of 1985. During January-February 1986, the evaporator tubes were removed to test a new tube bundle configuration (tube bundle C1). After only a short period of operation, tube diameter measurements show that tube wastage rates for bundle C1 were almost an order of magnitude larger than those recorded for B1. Although several other changes could have been responsible for this increase, the consensus at the TVA was that the increase probably occurred because the pilot plant switched coals from a low chlorine (0.02%) to a high chlorine ({approximately}0.30%) KY No. 9 coal. In order to determine the validity of the role of chlorine in increasing the tube wastage, several tube sections were cut out from the plant and analyzed. The results of the chemical and metallographic examination are reported.

    Reported here is the synthesis of a series of Polyurethane/POSS nanohybrid elastomers, the characterization of their thermal stability and degradation behavior at elevated temperatures using a combination of Thermal Gravimetric Analysis (TGA) and Thermal Volatilization Analysis (TVA). A series of PU elastomers systems have been formulated incorporating varying levels of 1,2-propanediol-heptaisobutyl-POSS (PHIPOSS) as a chain extender unit, replacing butane diol. The bulk thermal stability of the nanohybrid systems has been characterized using TGA. Results indicate that covalent incorporation of POSS into the PU elastomer network increase the non-oxidative thermal stability of the systems. TVA analysis of the thermal degradation of the POSS/PU hybrid elastomers have demonstrated that the hybrid systems are indeed more thermally stable when compared to the unmodified PU matrix; evolving significantly reduced levels of volatile degradation products and exhibiting a {approx}30 C increase in onset degradation temperature. Furthermore, characterization of the distribution of degradation products from both unmodified and hybrid systems indicate that the inclusion of POSS in the PU network is directly influencing the degradation pathways of both the soft and hard block components of the elastomers: The POSS/PU hybrid systems show reduced levels of CO, CO2, water and increased levels of THF as products of thermal degradation.

    The Tennessee Valley Authority (TVA) Technology Innovation, Energy Efficiency, Power Delivery and Utilization Office funded and managed a showcase demonstration located in the suburbs of west Knox county, Tennessee. Work started March 2008 with the goal of documenting best practices for retrofitting existing homes and for building new high-efficiency homes. The Oak Ridge National Laboratory and the Electric Power Research Institute (EPRI) provided technical support. An analytical base was developed for helping homeowners, homebuyers, builders, practitioners and the TVA make informed economic decisions for the materials and incentives necessary to build a new high-efficiency home or retrofit an existing home. New approaches to more efficiently control active energy subsystems and information for selecting or upgrading to Energy Star appliances, changing all lights to 100% CFL s and upgrading windows to low-E gas filled glazing yields a 40% energy savings with neutral cash flow for the homeowner. Passive designs were reviewed and recommendations made for envelope construction that is durable and energy efficient. The Campbell Creek project complements the DOE Building Technologies Program strategic goal. Results of the project created technologies and design approaches that will yield affordable energy efficient homes. The 2010 DOE retrofit goals are to find retrofit packages that attain 30% whole house energy savings as documented by pre and post Home Energy rating scores (HERS). Campbell Creek met these goals.

    Pacific Northwest National Laboratory is developing a technique to analyze Phasor Measurement Unit data to identify typical patterns, atypical events and precursors to a blackout or other undesirable event. The approach combines a data-driven multivariate analysis with an engineering-model approach. The method identifies atypical events, provides a plane English description of the event, and the capability to use drill-down graphics for detailed investigations. The tool can be applied to the entire grid, individual organizations (e.g. TVA, BPA), or specific substations (e.g., TVA_CUMB). The tool is envisioned for (1) event investigations, (2) overnight processing to generate a Morning Report that characterizes the previous days activity with respect to previous activity over the previous 10-30 days, and (3) potentially near-real-time operation to support the grid operators. This paper presents the current status of the tool and illustrations of its application to real world PMU data collected in three 10-day periods in 2007.

  7. Impact of incremental changes in meteorology on thermal compliance and power system operations

    1992-02-01

    The sensitivity of the TVA reservoir and power supply systems to extreme meteorology was evaluated using a series of mathematical models to simulate the relationship between incremental changes in meteorology, associated changes in water temperature, and power plant generation. Single variable analysis techniques were applied at selected TVA facilities for representative average and extreme weather conditions. In the analysis, base case simulations were first conducted for each representative year using observed meteorology (i.e., the no change condition). The impacts of changes in meteorology were subsequently analyzed by uniformly constant at their respective base case values. Project results are generally presented in terms of deviations from base case conditions for each representative year. Based on an analysis of natural flow and air temperature patterns at Chickamauga Dam, 1974 was selected to represent extreme cold-wet conditions; 1965 as reflecting average conditions; and 1986 as an example of an extremely hot-dry year. The extreme years (i.e., 1974 and 1986) were used to illustrate sensitivities beyond historical conditions; while the average year provided a basis for comparison. Observed reservoir conditions, such as inflows, dam releases, and reservoir elevations for each representative year, were used in the analysis and were assumed to remain constant in all simulations. Therefore, the Lake Improvement Plan (which was implemented in 1991) and its consequent effects on reservoir operations were not incorporated in the assessment. In the model simulations, computed water temperatures were based on vertically well-mixed conditions in the reservoirs.

    This report summarized the work accomplished during the fifth season of testing at TVA's EUTF. Previously, tests were conducted at the EUTF during the 1985/1986 summer and winter and the 1986/1987 summer and winter. This previous work at TVA, and work at the University of Mississippi, the FSEC, Texas A and M, and ORNL, have shown that in the summer: all RB installation locations provide large reductions in ceiling heat flux when used with R11 and R19 fiberglass, cellulose, or rock wool; reductions in ceiling heat flux from RBs when used with R30 are not nearly as large as from RBs when used with R19; the RBR and RBT provide sizable reductions in whole-house cooling loads; and the RBT provides the largest reduction in ceiling heat flux in most cases. Previous work has shown that in the winter: the RBT provides moderate ceiling heat flux reductions and whole-house heating load saving with R11 and R19 fiberglass, cellulose, or rock wool; the RBR shows very little reduction in ceiling heat flux in most cases; and reductions in ceiling heat flux with R30 are usually much less than with R11 or R19 insulation. 12 refs., 14 figs., 11 tabs.

    On December 22, 2008, over 4 million cubic meters of fly ash slurry was released into the Emory River when a dike surrounding a solid waste containment area at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant ruptured. One component of TVA's response to the spill is a biological monitoring program to assess short- and long-term ecological responses to the ash and associated chemicals, including studies on fish health and contaminant bioaccumulation. These studies were initiated in early Spring 2009 for the purposes of: (1) documenting the levels of fly ash-associated metals in various tissues of representative sentinel fish species in the area of the fly ash spill, (2) determining if exposure to fly ash-associated metals causes short, intermediate, or long-term health effects on these sentinel fish species, (3) assessing if there are causal relationships between exposure to metals and health effects on fish, (4) evaluating, along with information from other ecological and physicochemical studies, the nature and route of contaminant transfer though food chains into higher level consumers, (5) providing important information for the Ecological Risk Assessment (ERA) for the Kingston fly ash project, and (6) serving as an important technology information transfer or model study focused on how to best evaluate the environmental effects of fly ash (and related environmental stressors), not only at the Kingston site, but also at sites on other aquatic systems where coal-fired generating stations are located. This report presents the results of the first two years of the fish health study. To date, fish health and bioaccumulation studies have been conducted from Spring 2009 though Fall 2011 and includes 6 seasonal studies: Spring 2009, Fall 2009, Spring 2010, Fall 2010, Spring 2011, and Fall 2011. Both the Spring and Fall studies have focused on 3-4 sentinel fish species that represent different feeding habits, behaviors, and home ranges. In addition to fish

    This report describes the environmental radiological monitoring program conducted by TVA in the vicinity of Browns Ferry Nuclear Plant (BFN) in 1992. The program includes the collection of samples from the environment and the determination of the concentrations of radioactive materials in the samples. Samples are taken from stations in the general area of the plant and from areas not influenced by plant operations. Station locations are selected after careful consideration of the weather patterns and projected radiation doses to the various areas around the plant. Material sampled includes air, water, milk, foods, vegetation, soil, fish, sediment, and direct radiation levels. Results from stations near the plant are compared with concentrations from control stations and with preoperational measurements to determine potential impacts of plant operations. Small amounts of Co-60 and Cs-134 were found in sediment samples downstream from the plant. This activity in stream sediment would result in no measurable increase over background in the dose to the general public.

    Concern about the reliability of the 1,300 mw Cumberland steam turbine units after an unexpected blade tip failure in the fall of 1995 caused TVA to conduct an investigation into the current reliability of the L-O blades. A probabilistic model based on the measured frequencies, damping and material fatigue data was generated. The influence of significant erosion damage on the blade natural frequencies and on the local stresses was estimated. A probabilistic model of the local fatigue limit was generated based on test data. Monte Carlo simulation was employed to estimate the probability of blade failure by comparing the dynamic stress with the fatigue limit. Risk assessment of the blade failure is presented.

    The conceptual design of an 160 MW/sub e/ OTEC plantship has been documented; it is designed to produce 1000 tonne/day of fuel-grade methanol from coal slurry shipped to the plantship, using oxygen and hydrogen from the on-board electrolysis of water. Data and components are used that were derived by Brown and Root Development, Inc. (BARDI) in designing a barge-mounted plant to make methanol from natural gas for Litton Industries and in the design and construction of a coal-to-ammonia demonstration plant in operation at Muscle Shoals, Alabama, for the Tennessee Valley Authority (TVA). The OTEC-methanol plant design is based on the use of the Texaco gasifier and Lurgi synthesis units. The sale price of OTEC methanol delivered to port from this first-of-a-kind plant is estimated to be marginally competitive with methanol from other sources at current market prices.

    The Tennessee Valley Authority (TVA) reservoirs that are the subject of this report have been under investigation for several years due to contamination with polychlorinated biphenyls (PCBs). The study has two primary objectives: (1) define the geographical boundaries where contamination in fish ceases to be a problem and (2) determine the trend in PCB loading in fish from reservoirs where the contamination has been well defined. The purpose of this document is to briefly describe results of PCB analysis of fish collected from these reservoirs in autumn 1988 and compare them to results for previous years. These results were shared with all members on the study team as soon as they were received from the analytical laboratory rather than waiting for this formal report. Therefore, decisions on updating existing advisories and selection of study design for autumn 1989 were made months before this document was prepared. 6 refs., 21 tabs.

    TVA investigated water quality of Town Creek embayment using a branched two-dimensional model of Guntersville Reservoir. Simulation results were compared in terms of algal biomass, nutrient concentrations, and volume of embayment with depleted dissolved oxygen. Stratification and flushing play a significant role in the embayment water quality. Storms introduce large loadings of organics, nutrients, and suspended solids. Dissolved oxygen depletion is most severe after storms followed by low flow that fails to flush the embayment. Embayment water quality responses to potential animal waste and erosion controls were explored. Modeling indicated animal waste controls were much more cost-effective than erosion controls. Erosion controls will decrease embayment suspended solids and thereby increase algal biomass due to greater light penetration. 29 refs., 16 figs., 4 tabs.

    Analyses of postulated Anticipated Transients Without Scram (ATWS) were performed at the Idaho National Engineering Laboratory (INEL). The Browns Ferry Nuclear Plant Unit 1 (BFNP1) was selected as the subject of this work because of the cooperation of the Tennessee Valley Authority (TVA). The work is part of the Severe Accident Sequence Analysis (SASA) Program of the US Nuclear Regulatory Commission (NRC). A Main Steamline Isolation Valve (MSIV) closure served as the transient initiator for these analyses, which proceeded a complete failure to scram. Results from the analyses indicate that operator mitigative actions are required to prevent overpressurization of the primary containment. Uncertainties remain concerning the effectiveness of key mitigative actions. The effectiveness of level control as a power reduction procedure is limited. Power level resulting from level control only reduce the Pressure Suppression Pool (PSP) heatup rate from 6 to 4F/min.

    Critical Infrastructure control systems continue to foster predictable communication paths, static configurations, and unpatched systems that allow easy access to our nation's most critical assets. This makes them attractive targets for cyber intrusion. We seek to address these attack vectors by automatically randomizing network settings, randomizing applications on the end devices themselves, and dynamically defending these systems against active attacks. Applying these protective measures will convert control systems into moving targets that proactively defend themselves against attack. Sandia National Laboratories has led this effort by gathering operational and technical requirements from Tennessee Valley Authority (TVA) and performing research and development to create a proof-of-concept solution. Our proof-of-concept has been tested in a laboratory environment with over 300 nodes. The vision of this project is to enhance control system security by converting existing control systems into moving targets and building these security measures into future systems while meeting the unique constraints that control systems face.

    The largest environmental release of coal ash in U.S. history occurred in December 2008 with the failure of a retention structure at the Tennessee Valley Authority (TVA) Kingston Fossil Plant in East Tennessee. A byproduct of coal-burning power plants, coal ash is enriched in metals and metalloids such as selenium and arsenic with known toxicity to fish including embryonic and larval stages. The effects of contact exposure to sediments containing up to 78 % coal ash from the Kingston spill on the early development of fish embryos and larvae were examined in 7-day laboratory tests with the fathead minnow (Pimephales promelas). No significant effects were observed on hatching success, incidences of gross developmental abnormalities, or embryo-larval survival. Results suggest that direct exposures to sediment containing residual coal ash from the Kingston ash release may not present significant risks to fish eggs and larvae in waterways affected by the spill.

    In December 2009, the Southern Alliance for Clean Energy (SACE), through a partnership with the Appalachian Regional Commission, EKPC, Kentucky's Department for Energy Development and Independence, SACE, Tennessee's Department of Environment and Conservation, and TVA, and through a contract with the Department of Energy, established the Tennessee Valley and Eastern Kentucky Wind Working Group (TVEKWWG). TVEKWWG consists of a strong network of people and organizations. Working together, they provide information to various organizations and stakeholders regarding the responsible development of wind power in the state. Members include representatives from utility interests, state and federal agencies, economic development organizations, non-government organizations, local decision makers, educational institutions, and wind industry representatives. The working group is facilitated by the Southern Alliance for Clean Energy. TVEKWWG supports the Department of Energy by helping educate and inform key stakeholders about wind energy in the state of Tennessee.

    Under a consent agreement among the Environmental Protection Agency (EPA) and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity because many standard test species are more sensitive than resident species, thus could provide information useful to the rule-making. However, few laboratory studies of coal ash toxicity are available; most studies reported in the literature are based solely on field investigations. In this paper, we describe a broad range of toxicity studies conducted for the Tennessee Valley Authority (TVA) Kingston ash spill, results of which help provide additional perspective on the toxicity of coal ash.

    The TVA 20-MW AFBC Pilot Plant located near Paducah, Kentucky began operations in March 1982, and it operated with the same in-bed evaporator tubes (tube bundle B1) for {approximately}13,625 h through the end of 1985. During January--February 1986, the evaporator tubes were removed to test a new tube bundle configuration (tube bundle C1). After only a short period of operation, tube diameter measurements showed that tube wastage rates for bundle C1 were almost an order of magnitude larger than those recorded for B1. Although several other changes could have been responsible for this increase, the consensus at the TVA was that the increase probably occurred because the pilot plant switched coals from a low chlorine (0.02%) to a high chlorine ({approximately}0.30%) KY 9 coal. In order to determine the validity of the role of chlorine in increasing the tube wastage, several tube sections were cut out from the plant and analyzed at the Kentucky Energy Cabinet Laboratory (KECL) and at Argonne National Laboratory (ANL). The results of the chemical and metallographic examination showed that wastage could be attributed to erosive wear of chlorine-impregnated iron oxide scales. Corrosion component (oxidation) could have been altered by the presence of elements such as chlorine, sulfur, and potassium in the combustion gases. The results also showed that, in order to understand the complex deposition/corrosion phenomena that occur in FBC systems, it is imperative to characterize the local environment in the vicinity of the tube bundles. 5 refs., 16 figs.

    The 10 MW Demonstration of the Gas Suspension Absorption (GSA) program is a government and industry co-funded technology development. The objective of the project is to demonstrate the performance of the GSA system in treating a 10 MW slipstream of flue gas resulting from the combustion of a high sulfur coal. This project involves design, fabrication, construction and testing of the GSA system. The Project Performance and Economics Report provides the nonproprietary information for the ``10 MW Demonstration of the Gas Suspension Absorption (GSA) Project`` installed at Tennessee Valley Authority`s (TVA) Shawnee Power Station, Center for Emissions Research (CER) at Paducah, Kentucky. The program demonstrated that the GSA flue-gas-desulfurization (FGD) technology is capable of achieving high SO{sub 2} removal efficiencies (greater than 90%), while maintaining particulate emissions below the New Source Performance Standards (NSPS), without any negative environmental impact (section 6). A 28-day test demonstrated the reliability and operability of the GSA system during continuous operation. The test results and detailed discussions of the test data can be obtained from TVA`s Final Report (Appendix A). The Air Toxics Report (Appendix B), prepared by Energy and Environmental Research Corporation (EERC) characterizes air toxic emissions of selected hazardous air pollutants (HAP) from the GSA process. The results of this testing show that the GSA system can substantially reduce the emission of these HAP. With its lower capital costs and maintenance costs (section 7), as compared to conventional semi-dry scrubbers, the GSA technology commands a high potential for further commercialization in the United States. For detailed information refer to The Economic Evaluation Report (Appendix C) prepared by Raytheon Engineers and Constructors.

    Ztek`s Planar Solid Oxide Fuel Cell (SOFC) system has exceptional potential for utility electric power generation because of: simplicity of components construction, capability for low cost manufacturing, efficient recovery of very high quality by-product heat (up to 1000{degrees}C), and system integration simplicity. Utility applications of the Solid Oxide Fuel Cell are varied and include distributed generation units (sub-MW to 30MW capacity), repowering existing power plants (i.e. 30MW to 100MW), and multi-megawatt central power plants. A TVA/EPRI collaboration program involved functional testing of the advanced solid oxide fuel cell stacks and design scale-up for distributed power generation applications. The emphasis is on the engineering design of the utility modules which will be the building blocks for up to megawatt scale power plants. The program has two distinctive subprograms: Verification test on a 1 kW stack and 25kW module for utility demonstration. A 1 kW Planar SOFC stack was successfully operated for 15,000 hours as of December, 1995. Ztek began work on a 25kW SOFC Power System for TVA, which plans to install the 25kW SOFC at a host site for demonstration in 1997. The 25kW module is Ztek`s intended building block for the commercial use of the Planar SOFC. Systems of up to megawatt capacity can be obtained by packaging the modules in 2-dimensional or 3-dimensional arrays.

    2012-05-01

    On December 22, 2008, a dike containing fly ash and bottom ash in an 84-acre complex of the Tennessee Valley Authority's (TVA) Kingston Steam Plant in East Tennessee failed and released a large quantity of ash into the adjacent Emory River. Ash deposits extended as far as 4 miles upstream (Emory River mile 6) of the Plant, and some ash was carried as far downstream as Tennessee River mile 564 ({approx}4 miles downstream of the Tennessee River confluence with the Clinch River). A byproduct of coal burning power plants, fly ash contains a variety of metals and other elements which, at sufficient concentrations and in specific forms, can be toxic to biological systems. The effects of fly ash contamination on exposed fish populations depend on the magnitude and duration of exposure, with the most significant risk considered to be the effects of specific ash constituents, especially selenium, on fish early life stages. Uptake by adult female fish of fly ash constituents through the food chain and subsequent maternal transfer of contaminants to the developing eggs is thought to be the primary route of selenium exposure to larval fish (Woock and others 1987, Coyle and others 1993, Lemly 1999, Moscatello and others 2006), but direct contact of the fertilized eggs and developing embryos to ash constituents in river water and sediments is also a potential risk factor (Woock and others 1987, Coyle and others 1993, Jezierska and others 2009). To address the risk of fly ash from the Kingston spill to the reproductive health of downstream fish populations, ORNL has undertaken a series of studies in collaboration with TVA including: (1) a field study of the bioaccumulation of fly ash constituents in fish ovaries and the reproductive condition of sentinel fish species in reaches of the Emory and Clinch Rivers affected by the fly ash spill; (2) laboratory tests of the potential toxicity of fly ash from the spill area on fish embryonic and larval development (reported in the current

    This document describes lessons learned from designing, building, and monitoring five affordable, energy-efficient test houses in a single development in the Tennessee Valley Authority (TVA) service area. This work was done through a collaboration of Habitat for Humanity Loudon County, the US Department of Energy (DOE), TVA, and Oak Ridge National Laboratory (ORNL).The houses were designed by a team led by ORNL and were constructed by Habitat's volunteers in Lenoir City, Tennessee. ZEH5, a two-story house and the last of the five test houses to be built, provided an excellent model for conducting research on affordable high-performance houses. The impressively low energy bills for this house have generated considerable interest from builders and homeowners around the country who wanted a similar home design that could be adapted to different climates. Because a design developed without the project constraints of ZEH5 would have more appeal for the mass market, plans for two houses were developed from ZEH5: a one-story design (ZEH6) and a two-story design (ZEH7). This report focuses on ZEH6, identical to ZEH5 except that the geothermal heat pump is replaced with a SEER 16 air source unit (like that used in ZEH4). The report also contains plans for the ZEH6 house. ZEH5 and ZEH6 both use 50% less energy than the DOE Building America protocol for energyefficient buildings. ZEH5 is a 4 bedroom, 2.5 bath, 2632 ft2 house with a home energy rating system (HERS) index of 43, which qualifies it for federal energy-efficiency incentives (a HERS rating of 0 is a zero-energy house, and a conventional new house would have a HERS rating of 100). This report is intended to help builders and homeowners build similar high-performance houses. Detailed specifications for the envelope and the equipment used in ZEH5 are compared with the Building America Benchmark building, and detailed drawings, specifications, and lessons learned in the construction and analysis of data gleaned from 94

    TVA is collaborating with EPRI and DOE to demonstrate a passive treatment system for removing SCR-derived ammonia and trace elements from a coal-fired power plant wastewater stream. The components of the integrated system consist of trickling filters for ammonia oxidation, reaction cells containing zero-valent iron (ZVI) for trace contaminant removal, a settling basin for storage of iron hydroxide floc, and anaerobic vertical-flow wetlands for biological denitrification. The passive integrated treatment system will treat up to 0.25 million gallons per day (gpd) of flue gas desulfurization (FGD) pond effluent, with a configuration requiring only gravity flow to obviate the need for pumps. The design of the system will enable a comparative evaluation of two parallel treatment trains, with and without the ZVI extraction trench and settling/oxidation basin components. One of the main objectives is to gain a better understanding of the chemical transformations that species of trace elements such as arsenic, selenium, and mercury undergo as they are treated in passive treatment system components with differing environmental conditions. This progress report details the design criteria for the passive integrated system for treating fossil power plant wastewater as well as performance results from the first several months of operation. Engineering work on the project has been completed, and construction took place during the summer of 2005. Monitoring of the passive treatment system was initiated in October 2005 and continued until May 18 2006. The results to date indicate that the treatment system is effective in reducing levels of nitrogen compounds and trace metals. Concentrations of both ammonia and trace metals were lower than expected in the influent FGD water, and additions to increase these concentrations will be done in the future to further test the removal efficiency of the treatment system. In May 2006, the wetland cells were drained of FGD water, refilled with

    The Tennessee Valley Authority (TVA) Allen power plant is located on the Mississippi River in the southwest corner of Memphis, Tennessee. Allen has three coal-fired cyclone boilers with a rated capacity of 272 MW each. It is a Phase 2 plant under Title IV of the Clean Air Act and is the largest single source of NO{sub x} in the Memphis area. TVA plans to reduce Allen NOx emissions through a combination of burning low-sulfur coal (which has the benefit of reducing NO{sub x} emissions while also reducing SO{sub 2} emissions) and installing gas re-burn technology. A modeling study using the SAI, Inc., UAM-V photochemical model was conducted to examine the potential impacts of NO{sub x} reductions on ozone levels in the Memphis area. A series of four model simulations were made in which different Allen emissions scenarios were examined. The focus period of the photochemical modeling was 11--14 July 1995 when measurements in and near Memphis indicated peak hourly ozone levels of 135--140 ppb. This analysis primarily examined computed impacts within 50 km of Memphis. Allen was computed to contribute as much as 20--30 ppb to ground ozone levels 20-50 km downwind using its NO{sub x} emission rate before Title IV compliance. After compliance it was computed to contribute only about 10--20 ppb. At the same time, maximum daily ozone reductions due to Allen NO{sub x} titration of ozone were between 30 and 60 ppb. These benefits will be reduced by 30--50% after Title IV compliance, and are expected to occur within 30 km of the plant. More model grid cells indicated dis-benefits (net ground-level ozone increases) than benefits on three of the four episode days using the Title IV compliance emission rate. Significant ozone dis-benefits were expected because of the well-documented NO titration of ozone within plumes having a high ratio of NO to volatile organic compounds.

    Radiation has existed everywhere in the environment since the Earth's formation - in rocks, soil, water, and plants. The mining and processing of naturally occurring radioactive materials for use in medicine, power generation, consumer products, and industry inevitably generate emissions and waste. Radiological measuring devices have been used by industry for years to measure for radiation in undesired locations or simply identify radioactive materials. Since the terrorist attacks on the United States on 9-11-01 these radiation measuring devices have proliferated in many places in our nation's commerce system. DOE, TVA, the Army Corps and ORNL collaborated to test the usefulness of these devices in our nation's waterway system on this project. The purpose of the Watts Bar Dam ORNL Trusted Corridors project was to investigate the security, safety and enforcement needs of local, state and federal government entities for state-of-the-art sensor monitoring in regards to illegal cargo including utilization of the existing infrastructure. TVA's inland waterways lock system is a recognized and accepted infrastructure by the commercial carrier industry. Safety Monitoring activities included tow boat operators, commercial barges and vessels, recreational watercraft and their cargo, identification of unsafe vessels and carriers, and, monitoring of domestic and foreign commercial vessels and cargo identification. Safety Enforcement activities included cargo safety, tracking, identification of hazardous materials, waterway safety regulations, and hazardous materials regulations. Homeland Security and Law Enforcement Applications included Radiological Dispersive Devices (RDD) identification, identification of unsafe or illicit transport of hazardous materials including chemicals and radiological materials, and screening for shipments of illicit drugs. In the Fall of 2005 the SensorNet funding for the project expired. After several unsuccessful attempts to find a Federal sponsor

    Oak Ridge National Laboratory (ORNL) has been awarded $6.8 million in the Department of Energy (DOE) American Recovery and Reinvestment Act (ARRA) funds as part of an overall $114.8 million ECOtality grant with matching funds from regional partners to install 125 solar-assisted Electric Vehicle (EV) charging stations across Knoxville, Nashville, Chattanooga, and Memphis. Significant progress has been made toward completing the scope with the installation of 25 solar-assisted charging stations at ORNL; six stations at Electric Power Research Institute (EPRI); and 27 stations at Nissan's Smyrna and Franklin sites, with three more stations under construction at Nissan's new lithium-ion battery plant. Additionally, the procurement process for contracting the installation of 34 stations at Knoxville, the University of Tennessee Knoxville (UTK), and Nashville sites is underway with completion of installation scheduled for early 2012. Progress is also being made on finalizing sites and beginning installations of 30 stations in Nashville, Chattanooga, and Memphis by EPRI and Tennessee Valley Authority (TVA). The solar-assisted EV charging station project has made great strides in fiscal year 2011. A total of 58 solar-assisted EV parking spaces have been commissioned in East and Middle Tennessee, and progress on installing the remaining 67 spaces is well underway. The contract for the 34 stations planned for Knoxville, UTK, and Nashville should be underway in October with completion scheduled for the end of March 2012; the remaining three Nissan stations are under construction and scheduled to be complete in November; and the EPRI/TVA stations for Chattanooga, Vanderbilt, and Memphis are underway and should be complete by the end of March 2012. As additional Nissan LEAFs are being delivered, usage of the charging stations has increased substantially.

    Thanks to drastic cost cutting in the past 2 years, US enrichment plants now have the lowest cost production in the world, but US prices are still higher than those of overseas competitors because the business is paying for past mistakes. The most serious difficulty is that the Department of Energy (DOE), which owns and operates the US enrichment enterprise, is paying more than $500 million a year to the Tennessee Valley Authority (TVA) for electricity it once thought it would need but no longer requires. Another is that billions of dollars were spent in the 1970s and early 1980s to build new capacity that is now not needed. As a result, the enrichment enterprise has accumulated a debt to the US Treasury that the General Accounting Office (GAO) estimates at $8.8 billion. This paper presents the background and current debate in Congress about the difficulties facing the enrichment industry. In the midst of this debate over the future of the enterprise, the development of the next generation of enrichment technology is being placed in jeopardy. Known as atomic vapor laser isotope separation, or AVLIS, the process was viewed as the key to the long-term competitiveness of US enrichment. As the federal deficit mounted, however, funding for the AVLIS program was cut back and the timetable was stretched out. The US enrichment program has reached the point at which Congress will be forced to make some politically difficult decisions.

    This report describes the preoperational environmental radiological monitoring program conducted by TVA in the vicinity of the Watts Bar Nuclear Plant (WBN) in 1992. The program includes the collection of samples from the environment and the determination of the concentrations of radioactive materials in the samples. Samples are taken from stations in the general area of the plant and from areas that will not be influenced by plant operations. Material sampled includes air, water, milk, foods, vegetation, soil, fish, sediment, and direct radiation levels. During plant operations, results from stations near the plant will be compared with concentrations from control stations and with preoperational measurements to determine potential impacts to the public. Exposures calculated from environmental samples were contributed by naturally occurring radioactive materials, from materials commonly found in the environment as a result of atmospheric fallout, or from the operation of other nuclear facilities in the area. Since WBN has not operated, there has been no contribution of radioactivity from the plant to the environment.

    The major objectives of the SIEGate project were to improve the security posture and minimize the cyber-attack surface of electric utility control centers and to reduce the cost of maintaining control-room-to-control-room information exchange. Major project goals included the design, development, testing, and commercialization of a single security-hardened appliance that could meet industry needs for resisting cyber-attacks while protecting the confidentiality and integrity of a growing volume of real-time information needed to ensure the reliability of the bulk electric system and interoperating with existing data formats and networking technologies. The SIEGate project has achieved its goals and objectives. The SIEGate Design Document, issued in March 2012, presented SIEGate use cases, provided SIEGate requirements, established SIEGate design principles, and prescribed design functionality of SIEGate as well as the components that make up SIEGate. SIEGate Release Version 1.0 was posted in January 2014. Release Version 1.0.83, which was posted on March 28, 2014, fixed many issues discovered by early adopters and added several new features. Release Candidate 1.1, which added additional improvements and bug fixes, was posted in June 2014. SIEGate executables have been downloaded more than 300 times. SIEGate has been tested at PJM, Entergy, TVA, and Southern. Security testing and analysis of SIEGate has been conducted at PNNL and PJM. Alstom has provided a summary of recommended steps for commercialization of the SIEGate Appliance and identified two deployment models with immediate commercial application.

    In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4-9 g/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 g/g. In the present study we examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. While Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the five year period since the spill. Our results are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, our results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

Validate and refine parameters, which affect ethanol yield such as detoxification conditions mentioned above, and to fermenter conditions such as temperature, pH adjustment, aeration, nutrients, and charging sequence. Materials of construction will be evaluated also. Evaluate stillage to determine clarification process and suitability for recycle; evaluate lignocellulosic cake for thermal energy recovery to produce heat and electricity for the process; and Support Studies at UF - Toxin Amelioration and Fermentation; TVA work will provide pre-hydroylsates for the evaluation of BCI proprietary methods of toxin amelioration. Pre-hydrolysates from batch studies will allow the determination of the range of allowable hydrolyze conditions that can be used to produce a fermentable sugar stream. This information is essential to guide selection of process parameters for refinement and validation in the continuous pretreatment reactor, and for overall process design. Additional work will be conducted at UFRFI to develop improved strains that are resistant to inhibitors. The authors are quite optimistic about the long-term prospects for this advancement having recently developed strains with a 25%--50% increase in ethanol production. The biocatalyst platform selected originally, genetically engineered Escherichia coli B, has proven to be quite robust and adaptable.

    Multi-well pumping tests have been concluded at wells MW79, MW108, and PW1 at the Paducah Gaseous Diffusion Plant (PGDP) to determine the hydraulic properties of the Regional Gravel Aquifer (RGA). Soil cores suggest that the RGA consists of a thin sandy facies (2 to 6 feet) at the top of a thicker (> 10 feet) gravelly facies. Previous analyses have not considered any permeability contrast between the two facies. To assess the accuracy of this assumption, TVA personnel conducted borehole flowmeter tests at wells MW108 and PW1. Well MW79 could not be tested. The high K sand unit is probably 10 times more permeable than comparable zone in the gravelly portion of the RGA. Previous analyses of the three multi-well aquifer tests do not use the same conceptual aquifer model. Data analysis for one pumping test assumed that leakance was significant. Data analysis for another pumping test assumed that a geologic boundary was significant. By collectively analyzing all three tests with the borehole flowmeter results, the inconsistency among the three pumping tests can be explained. Disparity exists because each pumping test had a different placement of observation wells relative to the high K zone delineating by flowmeter testing.

    This report summarizes an indoor nitrogen dioxide (NO{sub 2}) sampling study conducted during January through March of 1987 in five Chattanooga public housing developments. The origins of this study date to the summer of 1983 when the Piney Woods Community Organization (a citizens action group) expressed concern about toxic industrial air pollution and the effects it might have on their community. In response to these concerns, the Chattanooga-Hamilton County Air Pollution Control Bureau (Bureau) requested assistance from the Tennessee Department of Health and Environment (TDHE) in conducting a community health survey and assistance from the Tennessee Valley Authority (TVA) in conducting a community air quality measurement program. The TDHE community health study did not find any significant differences between the mortality statistics for the Piney Woods community and a demographically similar control group. However, a health survey revealed that Piney Woods residents did not have a statistically significant higher self-reported prevalence of cough, wheezing, phlegm, breathlessness, colds, and respiratory illness.

    Changing to a dry ash disposal systems at Kingston Fossil Plant (KFP) raises several water quality issues. The first is that removing the fly ash from the ash pond could alter the characteristics of the ash pond discharge to the river. The second concerns proper disposal of the runoff and possibly leachate from the dry ash stack. The third is that dry ash stacking might change the potential for groundwater contamination at the KFP. This report addresses each of these issues. The effects on the ash pond and its discharge are described first. The report is intended to provide reference material to TVA staff in preparation of environmental review documents for new ash disposal areas at Kingston. Although the investigation was directed toward analysis of dry stacking, considerations for other disposal options are also discussed. This report was reviewed in draft form under the title Assessment of Kingston Fossil Plant Dry Ash Stacking on the Ash Pond and Groundwater Quality.'' 11 refs., 3 figs., 18 tabs.

    This report provides a summary of results from studies on invertebrate bioaccumulation of potential contaminants associated with a major fly ash spill into the Emory River following the failure of a dike at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant (KIF) in Kingston, Tennessee, in late December 2008. Data included in this report cover samples collected in calendar years 2009 and 2010. Samples collected from most sites in 2009 were processed by two different laboratories using different approved U.S. Environmental Protection Agency (EPA) analytical methods: ALS Laboratory Group in Ft. Collins, CO, processed sampling using EPA method 6010 (but method 6020 for uranium and SW7470 for mercury), and PACE Analytical in Minneapolis, MN, used EPA method 6020. A preliminary evaluation of results from both laboratories indicated that some differences exited in measured concentrations of several elements, either because of specific differences of the two methods or inter-laboratory differences. While concentration differences between the laboratories were noted for many elements, spatial trends depicted from the results of both methods appeared to be similar. However, because samples collected in the future will be analyzed by Method 6020, only the results from PACE were included in this report to reduce data variation potentially associated with inter-laboratory and analytical method differences.

    The Tennessee Valley Authority (TVA) has routinely monitored dissolved oxygen (DO) and temperature from the tailwater releases of its dams since the 1950s. The original objective of this monitoring was to collect baseline information to support reaeration research and determine the relative impact of impoundments on the assimilative capacity of the river system. This monitoring has continued even though the original objective was satisfied. New purposes for this monitoring data have arisen in support of several programs, without new consideration of the monitoring strategy and sampling design. The primary purpose of this report is to compare the historical release data for 30 dams in the Tennessee Valley based on four different objectives: (1) comparison of seasonal patterns, (2) comparison of baseline conditions using descriptive statistics, (3) evaluation of monotonic trends, and (4) discussion of monitoring strategies that might be required to determine compliance with existing and proposed criteria. A secondary purpose of the report is to compile the existing database into tables and figures that would be useful for other investigators. 51 refs., 210 figs., 1 tab.

    For over fifty years, the H Canyon facility at the Savannah River Site (SRS) has performed remotely operated radiochemical separations of irradiated targets to produce materials for national defense. Although the materials production mission has ended, the facility continues to play an important role in the stabilization and safe disposition of proliferable nuclear materials. As part of the US HEU Disposition Program, SRS has been down blending off-specification (off-spec) HEU to produce LEU since 2003. Off-spec HEU contains fission products not amenable to meeting the American Society for Testing and Material (ASTM) commercial fuel standards prior to purification. This down blended HEU material produced 301 MT of ~5% enriched LEU which has been fabricated into light water reactor fuel being utilized in Tennessee Valley Authority (TVA) reactors in Tennessee and Alabama producing economic power. There is still in excess of ~10 MT of off-spec HEU throughout the DOE complex or future foreign and domestic research reactor returns that could be recovered and down blended for beneficial use as either ~5% enriched LEU, or for use in subsequent LEU reactors requiring ~19.75% enriched LEU fuel.

    Building on the two previous trips to Central America last year, International Power Institute (IPI) and its partner Tennessee Valley Infrastructure Group (TVIG) have focused their attention this quarter on project sites in Honduras. TVIG's unit--an Integrated Infrastructure Platform or IIP--combines water and electricity production in a single integrated unit, thereby providing both products at a lower cost than could be attained for each one separately. Because of the unmet demand for clean drinking water and electricity in remote towns throughout the developing world, the need for such units is widespread. Previous visits to Honduras have resulted in strong in-country commercial interest, support in the form of memorandums of understanding by key government agencies, and identification of four prospective project sites for IIP installations. From March 5 to March 15 and with IPI support and participation, representatives from the TVIG, Tennessee Valley Authority (TVA), IPI, and market research firm International Business Initiatives (IBI) conducted an intensive survey of project opportunities in the four communities, to establish how IIPs might help these four communities enhance their economic development, A key aspect of the projects examined is the need to make them economically self-supporting so that they will be viable in the private sector. Summary of specific project site studies follow here, and feasibility studies for the four sites are included as attachments.

    Due to higher than expected permeation rates in the production of tritium in the TVA, a development and testing program was implemented to develop the understanding of why the higher rates were occurring. In addition, improved data are needed for both the design as well as the predictive models. One part of the program was to determine the equilibrium pressure of hydrogen and tritium over NPZ (1). During the course of this testing, some curious results were discovered (2) compared to the published literature data (3). Due to these apparently results, a follow-on task was undertaken to determine the equilibrium pressure of protium and deuterium over pure zirconium. A series of experiments were conducted to determine equilibrium pressures and isotherm data for the zirconium - protium and zirconium - deuterium systems. The data match the published literature data reasonably well with the plateau extending to loadings of about 1.4. There is a significant pressure rise for loadings greater than 1.7.

    On December 22, 2008, a dike containing fly ash and bottom ash at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant in East Tennessee failed and released a large quantity of ash into the adjacent Emory River. Ash deposits from the spill extended 4 miles upstream of the facility to Emory River mile 6 and downstream to Tennessee River mile 564 ({approx}8.5 miles downstream of the confluence of the Emory River with the Clinch River, and {approx}4 miles downstream of the confluence of the Clinch River with the Tennessee River). A byproduct of coal combustion, fly ash contains a variety of metals and other elements which, at sufficient concentrations and in specific forms, can be harmful to biological systems. The ecological effects of fly ash contamination on exposed fish populations depend on the magnitude and duration of exposure, with the most significant risk considered to come from elevated levels of certain metals in the ash, particularly selenium, on fish reproduction and fish early life stages (Lemly 1993; Besser and others 1996). The ovaries of adult female fish in a lake contaminated by coal ash were reported to have an increased frequency of atretic oocytes (dead or damaged immature eggs) and reductions in the overall numbers of developing oocytes (Sorensen 1988) associated with elevated body burdens of selenium. Larval fish exposed to selenium through maternal transfer of contaminants to developing eggs in either contaminated bodies of water (Lemly 1999) or in experimental laboratory exposures (Woock and others 1987, Jezierska and others 2009) have significantly increased incidences of developmental abnormalities. Contact of fertilized eggs and developing embryos to ash in water and sediments may also pose an additional risk to the early life stages of exposed fish populations through direct uptake of metals and other ash constituents (Jezierska and others 2009). The establishment and maintenance of fish populations is intimately associated with

The Tennessee Valley Authority's (TVA) Watts Bar-l received a low-power operating license from the U.S. Nuclear Regulatory Commission (NRC). The construction permit was granted in 1972. Also, TVA canceled plans to complete construction of three other nuclear plants. In 1995, federal and state governments took steps to deregulate and restructure the electric power industry. The Federal Energy Regulatory Commission (FERC) unanimously approved a proposal to require utilities to open their electric transmission system to competition from wholesale electricity suppliers. California has been at the forefront in the restructuring of the electric utility industry. Plans authorized by the California Public Utility Commission prepare for a free market in electricity to be established by 1998. In 1990, the U.S. Department of Energy (DOE) began reporting statistics on renewable energy consumption. The types and amounts of renewable energy consumed vary by end-use sector, electric utilities and the industrial sector being the primary consumers since 1990. Renewable energy provided 6.83 quads (7.6I) of the total energy consumed in the United States in 1995, compared to 7.1% in 1994. Increasing concern over the emission of greenhouse gases has resulted in exhaustive analysis of U.S. carbon emissions from energy use. Emissions in the early 1990s have already exceeded those projected by the Clinton Administration's Climate Change Action Plan (CCAP) released in 1994 that was developed to stabilize U.S. greenhouse gas emissions by the year 2000.

    Wind power development in the United States is outpacing previous estimates for many regions, particularly those with good wind resources. The pace of wind power deployment may soon outstrip regional capabilities to provide transmission and integration services to achieve the most economic power system operation. Conversely, regions such as the Southeastern United States do not have good wind resources and will have difficulty meeting proposed federal Renewable Portfolio Standards with local supply. There is a growing need to explore innovative solutions for collaborating between regions to achieve the least cost solution for meeting such a renewable energy mandate. The Department of Energy funded the project 'Integrating Midwest Wind Energy into Southeast Electricity Markets' to be led by EPRI in coordination with the main authorities for the regions: SPP, Entergy, TVA, Southern Company and OPC. EPRI utilized several subcontractors for the project including LCG, the developers of the model UPLAN. The study aims to evaluate the operating cost benefits of coordination of scheduling and balancing for Southwest Power Pool (SPP) wind transfers to Southeastern Electric Reliability Council (SERC) Balancing Authorities (BAs). The primary objective of this project is to analyze the benefits of regional cooperation for integrating mid-western wind energy into southeast electricity markets. Scenarios were defined, modeled and investigated to address production variability and uncertainty and the associated balancing of large quantities of wind power in SPP and delivery to energy markets in the southern regions of the SERC. DOE funded Oak Ridge National Laboratory to provide additional support to the project, including a review of results and any side analysis that may provide additional insight. This report is a unit-by-unit analysis of changes in operations due to the different scenarios used in the overall study. It focuses on the change in capacity factors and the number

    The BHEL/NTPC/PFC/TVA teams assembled at the DVC`s Chadrapura station on July 19, 1994, to assess the remaining life of Unit 2. The workscope was expanded to include major plant systems that impact the unit`s ability to sustain generation at 140 MW (Units 1-3 have operated at average rating of about 90 MW). Assessment was completed Aug. 19, 1994. Boiler pressure parts are in excellent condition except for damage to primary superheater header/stub tubes and economizer inlet header stub tubes. The turbine steam path is in good condition except for damage to LP blading; the spar rotor steam path is in better condition and is recommended for Unit 2. Nozzle box struts are severely cracked from the flame outs; the cracks should not be repaired. HP/IP rotor has surface cracks at several places along the steam seal areas; these cracks are shallow and should be machined out. Detailed component damage assessments for above damaged components have been done. The turbine auxiliary systems have been evaluated; cooling tower fouling/blockage is the root cause for the high turbine back pressure. The fuel processing system is one of the primary root causes for limiting unit capacity. The main steam and hot reheat piping systems were conservatively designed and have at least 30 years left;deficiencies needing resolution include restoration of insulation, replacement of 6 deformed hanger clamp/bolts, and adjustment of a few hanger settings. The cold reheat piping system is generally in good condition; some areas should be re-insulated and the rigid support clamps/bolts should be examined. The turbine extraction piping system supports all appeared to be functioning normally.

    In an attempt to determine if correlation exists between coal quality, as measured by its ash and sulfur contents, and the maintenance cost at utility plants, an examination was made of the actual maintenance cost experience of selected portions of five TVA coal-fired power plants as a function of the fuel quality consumed during an extended period of time. The results indicate that, according to our decision rules developed in compliance with accepted statistical practices, correlation does exist in many portions of the coal-fired plants for which sufficient maintenance cost records were available. The degree of correlation varies significantly among the individual portions of a particular plant as well as among the various plants. However, the indicators are sufficient to confirm that a change (within the design constraints of the unit) in the ash and/or sulfur content of the coal being consumed by a utility boiler will have a proportionate effect on the maintenance cost at the plant. In the cases examined, each percent variation in ash content could have a monetary effect of from $0.05 to $0.10 per ton of coal consumed. Similarly, each percent variation in sulfur content could influence maintenance costs from $0.30 to $0.50 per ton of coal. Since these values are based on preliminary analysis of limited data, they must be approached with caution and not removed from the context in which they are presented. However, if borne out by further study, the potential magnitude of such savings may be sufficient to justify the acquisition of superior coal supplies, either by changing the source and/or using preparation to obtain a lower ash and sulfur fuel.

    Near-surface soils, boreholes, and sediments near the Paducah Gaseous Diffusion Plant (PGDP) were sampled in 1989-91 as were monitoring wells, TVA wells, and privately-owned wells. Most wells were sampled two or three times. The resulting chemical analyses have been published in previous reports and have been previously described (CH2M HILL 1991, 1992; Clausen et al. 1992). The two reports by CH2M HILL are controversial, however, because, the concentrations of some constituents were reported to exceed background levels or drinking water standards and because both on-site (within the perimeter fence at PGDP) and off-site pollution was reported to have occurred. The groundwater samples upon which these interpretations were based may not be representative, however. The CH2M HILL findings are discussed in the report. The purpose of this report is to characterize the inorganic chemistry of groundwater and soils near PGDP, using data from the CH2M HILL reports (1991, 1992), and to determine whether or not any contamination has occurred. The scope is limited to analysis and interpretation of data in the CH2M HILL reports because previous interpretations of these data may not be valid, because samples were collected in a relatively short period of time at several hundred locations, and because the chemical analyses are nearly complete. Recent water samples from the same wells were not considered because the characterization of inorganic chemistry for groundwater and soil requirements only one representative sample and an accurate analysis from each location.

    The solar air heater testing demonstrated an attractive application for residential space heating, especially appealing to the do-it-yourself market. Simple improvements in construction, such as caulking of the glazing, could increase collector performance at little cost. The operating cost of the fan was insignificant, being less than $0.05/week. Tested in its as-shipped configuration at 96.1 cfm (3 cfm/ft/sup 2/), the useful energy delivered averaged 20,000 Btu/day for six days in December. The electrical consumption of the fan was approximately 1 kWh. Doubling the flowrate did not increase collector performance appreciably. A TRNSYS computer simulation model for this solar air heater design was validated by comparing the measured test data on January 4, 1981 with calculated values. TRNSYS predicted the measured collector outlet temperatures within +- 1.2/sup 0/F and the energy delivered within +- 3%. The excellent agreement was obtained by adjusting the collector loss coefficient to an unrealistically low value; therefore, a parametric study is recommended to determine the model sensitivity to varying different parameters. A first-order collector efficiency curve was derived from the TRNSYS simulations which compared well with the curve defined by the clear-day measured data. In addition, a linear equation for the monthly efficiency that allows a calculation of energy savings for any location was derived from simulated data. The annual energy delivered by the air heater is calculated for three cities using hourly TRNSYS simulations and Typical Meteorological Year (TMY) data. The approximate cost of materials for the heater is $144 maximum. Discounting 40% for the federal tax credit, the cost is $86. Based on 1981 electrical rates of $0.04/kWh, 2-1/2 to 3 heating seasons are required to pay back the initial cost of one collector in the TVA region.

    A collaborative research between the Oak Ridge National Laboratory (ORNL), the American Electric Power (AEP), the Tennessee Valley Authority (TVA), and the State of Ohio Energy Office (OEO) has been formed to conduct a feasibility study to detect and locate partial discharges (PDs) inside large transformers. The success of early detection of the PDs is necessary to avoid costly catastrophic failures that can occur if the process of PD is ignored. The detection method under this research is based on an innovative technology developed by ORNL researchers using optical methods to sense the acoustical energy produced by the PDs. ORNL researchers conducted experimental studies to detect PD using an optical fiber as an acoustic sensor capable of detecting acoustical disturbances at any point along its length. This technical approach also has the potential to locate the point at which the PD was sensed within the transformer. Several optical approaches were experimentally investigated, including interferometric detection of acoustical disturbances along the sensing fiber, light detection and ranging (LIDAR) techniques using frequency modulation continuous wave (FMCW), frequency modulated (FM) laser with a multimode fiber, FM laser with a single mode fiber, and amplitude modulated (AM) laser with a multimode fiber. The implementation of the optical fiber-based acoustic measurement technique would include installing a fiber inside a transformer allowing real-time detection of PDs and determining their locations. The fibers are nonconductive and very small (core plus cladding are diameters of 125 μm for single-mode fibers and 230 μm for multimode fibers). The research identified the capabilities and limitations of using optical technology to detect and locate sources of acoustical disturbances such as in PDs in large transformers. Amplitude modulation techniques showed the most promising results and deserve further research to better quantify the technique’s sensitivity

    Two 1,000-hour burns were conducted with the 12-inch (0.3m) laboratory AFBC system at Western Kentucky University. Operating conditions similar to those used at the 160 MW AFBC system at the TVA Shawnee Steam Plant located near Paducah, KY were used. A 1,000-hour burn was done with a low-chlorine (0.012% Cl and 3.0% S) Western Kentucky No.9 coal. A second 1,000-hour burn was conducted with high-chlorine (0.28% Cl and 2.4% S) Illinois No.6 coal. Four different metal alloys [carbon steel C1020 (0.18% C and 0.05% Cr), 304 SS (18.39% Cr and 8.11% Ni), 309 SS (23.28% Cr and 13.41% Ni), and 347 SS (18.03% Cr and 9.79% Ni)] were exposed uncooled in the freeboard at the entrance to the convection pass, where the metal temperature was approximately 900K. The carbon steel samples were essentially destroyed. However, it was expected that C1020 carbon steel samples would not withstand the high temperatures selected for the testing. A small amount of scale failure was observed on the other three samples in both test runs. Based on the SEM-EDS mapping results, there is no localized chloride distribution observed on the surface of the coupons, neither in the scale failure area nor on the rest of the metal part. Some trace amounts of chloride was found, but it was evenly distributed on the surface of the coupons. There is no concentration of chloride on the spot of scale failure. The scale failure might be due to sulfur attack and/or the effect of erosion. Further study with higher chlorine content coals for more conclusive information is needed.

    The Tennessee Valley Authority recently issued for public review a Draft Environmental Impact Statement for the conversion of the unfinished Bellefonte Nuclear Plant to fossil fuel. The DEIS was structured to support three tiers of decision making. Tier 1 is to decide between the No-Action Alternative, which is to leave Bellefonte as a partially completed nuclear plant into the indefinite future, and the Proposed Action Alternative, which is to proceed with converting Bellefonte to fossil fuel. Tier 2 is to select one of five conversion options. In the DEIS, TVA indicated no preference among the five competing fossil conversion options. The five conversion pathways would fully repower the plant consistent with fossil fuel availability, would use commercially ready systems and technologies and be designed to fully utilize the capacity of transmission lines serving Bellefonte. Conversion options addressed were pulverized coal (PC), natural gas combined cycle (NGCC), integrated gasification combined cycle (IGCC), IGCC with joint production of electricity and chemicals, and an option, which combines elements of NGCC and IGCC with coproduction. Tier 3 involves decisions about eight sub-option choices, basically types of processes, equipment, and modes of operation, which is part of two or more conversion options. An example of a sub-option choice would be the type of gasifier that would be used in conversion options involving coal or petroleum coke gasification. Other sub-option choices addressed in the DEIS were natural gas pipeline corridors; fuels, feedstocks, and by-products transportation modes; types of combustion turbines; solid fuels; types of boilers for conventional coal-fired options; chemical production mixes; and modes of onsite solid fuel conveyance. The impact of constructing and operating each proposed fossil conversion option at Bellefonte were evaluated for 18 environmental resource and economic categories.

    The main objective of this project was to investigate the potential environmental impact of the storage or disposal of coal gasification residues. In this regard, this investigation examined the quality of leachate produced during the long-term outdoor storage slag generated at the TVA 200-t/d Texaco gasifier in Muscle Shoals, Alabama. Evaluative laboratory extraction tests were also conducted on both the coarse and fine slag. Leachate quality was tracked in both the surface water and the water at depth after it percolated through the slag pile (leachate well water) by measuring pH and conductivity on a weekly basis and toxic trace elements and other chemical species quarterly or at longer intervals. The major species observed in the leachate well water were Ca and Mg cations as well as sulfate anions. The average electrical conductivity measured in the leachate well water was 2503 {mu}mhos/cm. The measured pH decreased from an initial value of 8.2 and stabilized at about 7.1 with occasional excursions to values as low as 6.3 during dry periods. Concurrently, sulfate concentrations averaged 1083 mg/l with occasional peaks as high as 2600 mg/l. Fe and Mn concentrations measured in the leachate well waters averaged 2.0 and 1.68 mg/l, respectively. Concentrations of species for which Primary Maximum Contaminant Limits (MCLs) for public drinking water supplies have been established were generally below the primary limits with the exception of Se and F which exceeded the limits occasionally. Concentrations of Fe, Mn, sulfate, and total dissolved solids were markedly above the Secondary MCLs set for these species. 35 refs., 2 figs., 21 tabs.

The CCWESTRS is growing commercial grade trees and cover crops and is expected to sequester 1.5-2.0 MT/ha carbon per year over a 20-year period. The concept could be used to meet a portion of the timber industry's needs while simultaneously sequestering carbon in lands which would otherwise remain non-productive. The CCWESTRS includes a constructed wetland to enhance the ability to sequester carbon and to remove any nutrients and metals present in the coal fly ash process water runoff. The CCWESTRS project is a cooperative effort between TVA, EPRI, and DOE-NETL, with a total budget of $1,574,000. The proposed demonstration project began in October 2000 and has continued through December 2005. Additional funding is being sought in order to extend the project. The primary goal of the project is to determine if integrating power plant processes with carbon sequestration techniques will enhance carbon sequestration cost-effectively. This goal is consistent with DOE objectives to provide economically competitive and environmentally safe options to offset projected growth in U.S. baseline emissions of greenhouse gases after 2010, achieve the long-term goal of $10/ton of avoided net costs for carbon sequestration, and provide half of the required reductions in global greenhouse gases by 2025

    This document summarizes progress on Cooperative Agreement DE-FC26-99FT40718, Furnace Injection of Alkaline Sorbents for Sulfuric Acid Control, during the time period April 1, 2001 through September 30, 2001. The objective of this project is to demonstrate the use of alkaline reagents injected into the furnace of coal-fired boilers as a means of controlling sulfuric acid emissions. The coincident removal of hydrochloric acid and hydrofluoric acid is also being determined, as is the removal of arsenic, a known poison for NO{sub x} selective catalytic reduction (SCR) catalysts. EPRI, the Tennessee Valley Authority (TVA), FirstEnergy Corporation, and the Dravo Lime Company are project co-funders. URS Corporation is the prime contractor. During the current period, American Electric Power (AEP) joined the project as an additional co-funder and as a provider of a host site for testing. This is the fourth reporting period for the subject Cooperative Agreement. During this period, two long-term sorbent injection tests were conducted, one on Unit 3 at FirstEnergy's Bruce Mansfield Plant (BMP) and one on Unit 1 at AEP's Gavin Station. These tests determined the effectiveness of injecting alkaline slurries into the upper furnace of the boiler as a means of controlling sulfuric acid emissions from these units. The alkaline slurries tested included commercially available magnesium hydroxide slurry (Gavin Station), and a byproduct magnesium hydroxide slurry (both Gavin Station and BMP). The tests showed that injecting either the commercial or the byproduct magnesium hydroxide slurry could achieve up to 70 to 75% sulfuric acid removal. At BMP, the overall removal was limited by the need to maintain acceptable electrostatic precipitator (ESP) particulate control performance. At Gavin Station, the overall sulfuric acid removal was limited because the furnace injected sorbent was less effective at removing SO{sub 3} formed across the SCR system installed on the unit for NO{sub x

    The Campbell Creek project is funded and managed by the Tennessee Valley Authority (TVA) Technology Innovation, Energy Efficiency, Power Delivery & and Utilization Office. Technical support is provided under contract by the Oak Ridge National Laboratory (ORNL) and the Electric Power Research Institute.The project was designed to determine the relative energy efficiency of typical new home construction, energy efficiency retrofitting of existing homes, and high -performance new homes built from the ground up for energy efficiency. This project will compare three houses that represented the current construction practice as a base case (Builder House CC1); a modified house that could represent a major energy- efficient retrofit (Retrofit House CC2); and a house constructed from the ground up to be a high- performance home (High Performance House CC3). In order tTo enablehave a valid comparison, it was necessary to simulate occupancy in all three houses and heavily monitor the structural components and the energy usage by component. All three houses are two story, slab on grade, framed construction. CC1 and CC2 are approximately 2,400 square feet2. CC3 has a pantry option, that is primarily used as a mechanical equipment room, that adds approximately 100 square feet2. All three houses are all-electric (with the exception of a gas log fireplace that is not used during the testing), and use air-source heat pumps for heating and cooling. The three homes are located in Knoxville in the Campbell Creek Subdivision. CC1 and CC2 are next door to each other and CC3 is across the street and a couple of houses down. The energy data collected will be used to determine the benefits of retrofit packages and high -performance new home packages. There are over 300 channels of continuous energy performance and thermal comfort data collection in the houses (100 for each house). The data will also be used to evaluate the impact of energy -efficient upgrades ton the envelope, mechanical

For instance, the study includes an evaluation of the effectiveness of the fuel cell's synthesized relay protection scheme relative to the recently issued IEEE 1547 interconnection standard. Together, these activities should serve to reduce the number of unknowns pertaining to unconventional protective circuits, to the benefit of DG manufacturers, vendors, prospective and current users of DG, and electricity suppliers/distributors. Although more grid-connect fuel cell interruptions were encountered in this study than originally anticipated, and the investigation and findings became quite complex, every effort was made to clearly summarize the interconnection causes and issues throughout the report and especially in the summary found in Sect. 4.

    H Canyon is considering a flowsheet change for Plutonium (Pu) Contaminated Scrap (PuCS) material. The proposed change is to route dissolved PuCS material directly to a uranium (U) storage tank. As a result, the PuCS solution will bypass Head End and First U Cycle, and will be purified by solvent extraction in Second U Cycle. The PuCS solution contains appreciable amounts of boron (B) and fluoride (F{sup -}), which are currently at trace levels in the U storage tank. Though unlikely, if the B concentration in the U storage tank were to reach 1.8 g B/g U, the entire contents of the U storage tank would likely require a second pass through Second U Cycle to provide sufficient decontamination to meet the Tennessee Valley Authority (TVA) Blend Grade Highly Enriched Uranium (HEU) specification for B, which is 30 {micro}g/g U. In addition, Second U Cycle is expected to provide sufficient decontamination of F{sup -} and Pu regardless of the amount of PuCS solution sent to the storage tank. Though aluminum (Al) is not present in the PuCS solution, B can be credited as a complexant of F{sup -}. Both stability constants from the literature and Savannah River National Laboratory (SRNL) corrosion studies were documented to demonstrate that B complexation of F{sup -} in nitric acid solutions is sufficient to prevent excessive corrosion. Though B and Al complex F{sup -} to a similar degree, neither completely eliminates the presence of free F{sup -} in solution. Therefore, a limited amount of corrosion is expected even with complexed F{sup -} solutions. Tanks maintained at ambient temperature are not expected to experience significant corrosion. However, the Low Activity Waste (LAW) evaporators may be subjected to a corrosion rate of about 25 mils per year (mpy) as they reach their highest F{sup -} concentrations. The feed adjustment evaporator would only be subjected to the corrosion rate of about 25 mpy in the latter stages of the PuCS campaign. An issue that must be addressed

    In December 2008, an earthen retaining wall at the Tennessee Valley Authority (TVA) Kingston Fossil Fuel Plant failed and released 4.1 million m3 of coal ash to rivers flowing into Watts Bar Reservoir in east Tennessee, United States (U.S.). As part of a comprehensive effort to evaluate the risks to aquatic resources from this spill – the largest in U.S. history – we compared bioaccumulation and maternal transfer of selenium (Se), arsenic (As), and mercury (Hg) in adult redear sunfish (Lepomis macrolophus), collected two years after the spill from both coal-ash exposed and non-exposed areas of the Emory and Clinchmore » Rivers, with the success of embryo-larval development in their offspring. Whole body and ovary concentrations of Se in female sunfish at three study sites downstream of the spill were significantly elevated (site means = 4.9–5.3 and 6.7–9.0 mg/kg d.w. whole body and ovary concentrations, respectively) compared with concentrations in fish from reference sites upstream of the spill site (2.2–3.2 mg/kg d.w. for whole bodies and 3.6–4.8 mg/kg d.w. for ovaries). However, Se concentrations in coal ash-exposed areas remain below proposed U.S. Environmental Protection Agency (USEPA) criteria for the protection of aquatic life. Site-to-site variation in fish concentrations of As and Hg were not well-correlated with ash-exposure, reflecting the multiple sources of these metal(loid)s in the affected watersheds. In 7-day laboratory tests of embryos and larvae derived from in vitro crosses of eggs and sperm from these field-collected sunfish, fertilization success, hatching success, embryo-larval survival, and incidences of developmental abnormalities did not differ significantly between ash-exposed and non-exposed fish. Furthermore, these developmental endpoints were not correlated with whole body or ovary concentrations of Se, As, or Hg in the maternal fish, or with fish size, ovary weight, or gonadal-somatic indices. Furthermore, results from

    In December 2008, an ash dike at the Tennessee Valley Authority (TVA) Kingston Fossil Plant ruptured, releasing over one billion gallons of coal fly ash into the Emory and Clinch Rivers. Coal fly ash may contain several contaminants of concern, but of these selenium (Se) and arsenic (As) have been highlighted because of their toxicity and tendency to bioaccumulate in aquatic food chains. To assess the potential impact of the spilled fly ash on humans and the environment, a comprehensive biological and environmental monitoring program was established, for which resident aquatic organisms (among other sample media) are collected to determine contaminant exposure and evaluate the risk to humans and wildlife. Studies on bioaccumulation and fish health are major components of the TVA Biological Monitoring Program for the Kingston fly ash project. These studies were initiated in early Spring 2009 for the purposes of: (1) documenting the levels of fly ash-associated metals in various tissues of representative sentinel fish species in the area of the fly ash spill, (2) determining if exposure to fly ash-associated metals causes short, intermediate, or long-term health effects on these sentinel fish species, (3) assessing if there are causal relationships between exposure (to metals) and effects on fish, (4) evaluating, along with information regarding other ecological and physicochemical studies, the nature and route of contaminant transfer though food chains into higher level consumers, (5) providing important information for the Ecological Risk Assessment (ERA) for the Kingston fly ash project, and (6) serving as an important technology transfer or model study focused on how to best evaluate the environmental effects of fly ash, not only at the Kingston site, but also at sites on other aquatic systems where coal-fired generating stations are located. This report summarizes the bioaccumulation results from the first two years of study after the fly ash spill, including

    Wind power development in the United States is outpacing previous estimates for many regions, particularly those with good wind resources. The pace of wind power deployment may soon outstrip regional capabilities to provide transmission and integration services to achieve the most economic power system operation. Conversely, regions such as the Southeastern United States do not have good wind resources and will have difficulty meeting proposed federal Renewable Portfolio Standards with local supply. There is a growing need to explore innovative solutions for collaborating between regions to achieve the least cost solution for meeting such a renewable energy mandate. The DOE-funded project 'Integrating Southwest Power Pool Wind Energy into Southeast Electricity Markets' aims to evaluate the benefits of coordination of scheduling and balancing for Southwest Power Pool (SPP) wind transfers to Southeastern Electric Reliability Council (SERC) Balancing Authorities (BAs). The primary objective of this project is to analyze the benefits of different balancing approaches with increasing levels of inter-regional cooperation. Scenarios were defined, modeled and investigated to address production variability and uncertainty and the associated balancing of large quantities of wind power in SPP and delivery to energy markets in the southern regions of the SERC. The primary analysis of the project is based on unit commitment (UC) and economic dispatch (ED) simulations of the SPP-SERC regions as modeled for the year 2022. The UC/ED models utilized for the project were developed through extensive consultation with the project utility partners, to ensure the various regions and operational practices are represented as accurately as possible realizing that all such future scenario models are quite uncertain. SPP, Entergy, Oglethorpe Power Company (OPC), Southern Company, and the Tennessee Valley Authority (TVA) actively participated in the project providing input data for the models

    This document presents and discusses results from Cooperative Agreement DE-FC26-06NT42778, 'Full-scale Testing of a Mercury Oxidation Catalyst Upstream of a Wet FGD System,' which was conducted over the time-period July 24, 2006 through June 30, 2010. The objective of the project was to demonstrate at full scale the use of solid honeycomb catalysts to promote the oxidation of elemental mercury in pulverized-coal-fired flue gas. Oxidized mercury is removed downstream in wet flue gas desulfurization (FGD) absorbers and collected with the byproducts from the FGD system. The project was co-funded by EPRI, the Lower Colorado River Authority (LCRA), who also provided the host site, Great River Energy, Johnson Matthey, Southern Company, Salt River Project (SRP), the Tennessee Valley Authority (TVA), NRG Energy, Ontario Power and Westar. URS Group was the prime contractor and also provided cofunding. The scope of this project included installing and testing a gold-based catalyst upstream of one full-scale wet FGD absorber module (about 200-MW scale) at LCRA's Fayette Power Project (FPP) Unit 3, which fires Powder River Basin coal. Installation of the catalyst involved modifying the ductwork upstream of one of three wet FGD absorbers on Unit 3, Absorber C. The FGD system uses limestone reagent, operates with forced sulfite oxidation, and normally runs with two FGD modules in service and one spare. The full-scale catalyst test was planned for 24 months to provide catalyst life data. Over the test period, data were collected on catalyst pressure drop, elemental mercury oxidation across the catalyst module, and mercury capture by the downstream wet FGD absorber. The demonstration period began on May 6, 2008 with plans for the catalyst to remain in service until May 5, 2010. However, because of continual increases in pressure drop across the catalyst and concerns that further increases would adversely affect Unit 3 operations, LCRA decided to end the demonstration early, during

The project was designed to determine the relative energy efficiency of typical new home construction, of retrofitting of existing homes, and of high-performance new homes built from the ground up for energy efficiency. This project was designed to compare three houses that represent current construction practices: a base case (Builder House CC1); a modified house that could represent a major energy-efficient retrofit (Retrofit House CC2); and a house constructed from the ground up to be a high-performance home (High Performance House CC3). To enable a valid comparison, it was necessary to simulate occupancy in all three houses and extensively monitor the structural components and the energy usage by component. In October 2013, the base case was also modified by replacing the builder-grade heating, ventilation, and air-conditioning (HVAC) system with a high-efficiency variable-speed unit. All three houses are two-story, slab-on-grade, framed construction. CC1 and CC2 are approximately 2,400 ft2. CC3 has a pantry option, used primarily as a mechanical equipment room, that adds approximately 100 ft2. All three houses are all-electric (with the exception of a gas log fireplace that is not used during the testing) and use air-source heat pumps for heating and cooling. The three homes are located in Knoxville in the Campbell Creek Subdivision. CC1 and CC2 are next door to each other with a south-facing orientation; CC3 has a north-facing orientation and is located across the street and a couple of houses down.

    sediments by more than 2000-fold) in the 1980s, mercury concentrations in EFPC fish exceeded those in fish from regional reference sites by only a little more than 10-fold. This apparent low bioavailability of mercury in EFPC, coupled with a downstream pattern of mercury in fish in which mercury decreased in proportion to dilution of the upstream source, lead to the assumption that mercury in fish would respond to decreased inputs of dissolved mercury to the stream's headwaters. However, during the past two decades when mercury inputs were decreasing, mercury concentrations in fish in Lower EFPC (LEFPC) downstream of Y-12 increased while those in Upper EFPC (UEFPC) decreased. The key assumption of the ongoing cleanup efforts, and concentration goal for waterborne mercury were both called into question by the long-term monitoring data. The large inventory of mercury within the watershed downstream presents a concern that the successful treatment of sources in the headwaters may not be sufficient to reduce mercury bioaccumulation within the system to desired levels. The relative importance of headwater versus floodplain mercury sources in contributing to mercury bioaccumulation in EFPC is unknown. A mercury transport study conducted by the Tennessee Valley Authority (TVA) in 1984 estimated that floodplain sources contributed about 80% of the total annual mercury export from the EFPC system (ORTF 1985). Most of the floodplain inputs were associated with wet weather, high flow events, while much of the headwater flux occurred under baseflow conditions. Thus, day-to-day exposure of biota to waterborne mercury was assumed to be primarily determined by the Y-12 source. The objective of this study was to evaluate the results of recent studies and monitoring within the EFPC drainage with a focus on discerning the magnitude of floodplain mercury sources and how long these sources might continue to contaminate the system after headwater sources are eliminated or greatly reduced.

    In response to the Department of Energy (DOE) funded initiative to develop and deploy lead fuel assemblies (LFAs) of Enhanced Accident Tolerant Fuel (EATF) into a US reactor within 10 years, AREVA put together a team to develop promising technologies for improved fuel performance during off normal operations. This team consisted of the University of Florida (UF) and the University of Wisconsin (UW), Savannah River National Laboratory (SRNL), Duke Energy and Tennessee Valley Authority (TVA). This team brought broad experience and expertise to bear on EATF development. AREVA has been designing; manufacturing and testing nuclear fuel for over 50 years and is one of the 3 large international companies supplying fuel to the nuclear industry. The university and National Laboratory team members brought expertise in nuclear fuel concepts and materials development. Duke and TVA brought practical utility operating experience. This report documents the results from the initial “discovery phase” where the team explored options for EATF concepts that provide enhanced accident tolerance for both Design Basis (DB) and Beyond Design Basis Events (BDB). The main driver for the concepts under development were that they could be implemented in a 10 year time frame and be economically viable and acceptable to the nuclear fuel marketplace. The economics of fuel design make this DOE funded project very important to the nuclear industry. Even incremental changes to an existing fuel design can cost in the range of $100M to implement through to LFAs. If this money is invested evenly over 10 years then it can take the fuel vendor several decades after the start of the project to recover their initial investment and reach a breakeven point on the initial investment. Step or radical changes to a fuel assembly design can cost upwards of $500M and will take even longer for the fuel vendor to recover their investment. With the projected lifetimes of the current generation of nuclear power
