Future nuclear fuel cycles: prospects and challenges  

Science Conference Proceedings (OSTI)

Solvent extraction has played, from the early steps, a major role in the development of nuclear fuel cycle technologies, both in the front end and back end. Today's stakes in the field of energy enhance further than before the need for a sustainable management of nuclear materials. Recycling actinides appears as a main guideline, as much for saving resources as for minimizing the final waste impact, and many options can be considered. Strengthened by the important and outstanding performance of recent PUREX processing plants, solvent-extraction processes seem a privileged route to meet the new and challenging requirements of sustainable future nuclear systems.

Issue and challenges facing rechargeable thin film lithium batteries  

Science Conference Proceedings (OSTI)

New materials hold the key to fundamental advances in energy conversion and storage, both of which are vital in order to meet the challenge of global warming and the finite nature of fossil fuels. Nanomaterials in particular offer unique properties or combinations of properties as electrodes and electrolytes in a range of energy devices. Technological improvements in rechargeable solid-state batteries are being driven by an ever-increasing demand for portable electronic devices. Lithium batteries are the systems of choice, offering high energy density, flexible, lightweight design and longer lifespan than comparable battery technologies. We present a brief historical review of the development of lithium-based thin film rechargeable batteries highlight ongoing research strategies and discuss the challenges that remain regarding the discovery of nanomaterials as electrolytes and electrodes for lithium batteries also this article describes the possible evolution of lithium technology and evaluates the expected improvements, arising from new materials to cell technology. New active materials under investigation and electrode process improvements may allow an ultimate final energy density of more than 500 Wh/L and 200 Wh/kg, in the next 5-6 years, while maintaining sufficient power densities. A new rechargeable battery technology cannot be foreseen today that surpasses this. This report will provide key performance results for thin film batteries and highlight recent advances in their development.

Technical challenges for the future of high energy lasers  

SciTech Connect

The Solid-State, Heat-Capacity Laser (SSHCL) program at Lawrence Livermore National Laboratory is a multi-generation laser development effort scalable to the megawatt power levels with current performance approaching 100 kilowatts. This program is one of many designed to harness the power of lasers for use as directed energy weapons. There are many hurdles common to all of these programs that must be overcome to make the technology viable. There will be a in-depth discussion of the general issues facing state-of-the-art high energy lasers and paths to their resolution. Despite the relative simplicity of the SSHCL design, many challenges have been uncovered in the implementation of this particular system. An overview of these and their resolution are discussed. The overall system design of the SSHCL, technological strengths and weaknesses, and most recent experimental results will be presented.

The future of IAEA safeguards: challenges and responses  

SciTech Connect

For nearly two decades, the International Atomic Energy Agency (lAEA) has been transforming its safeguards system to address the challenges posed by undeclared nuclear programs, the associated revelation of an extensive non-State nuclear procurement network and other issues, including past limits to its verification mandate and the burden of noncompliance issues. Implementing the new measures, including those in the Additional Protocol, and integrating new and old safeguards measures, remains a work in progress. Implementation is complicated by factors including the limited teclmological tools that are available to address such issues as safeguarding bulk handling facilities, detection of undeclared facilities/activities, especially related to enrichment, etc. As this process continues, new challenges are arising, including the demands of expanding nuclear power production worldwide, so-called safeguards by design for a new generation of facilities, the possible IAEA role in a fissile material cutoff treaty and other elements of the arms control and disarmament agenda, the possible role in 'rollback' cases, etc. There is no doubt safeguards will need to evolve in the future, as they have over the last decades. In order for the evolutionary path to proceed, there will inter alia be a need to identify technological gaps, especially with respect to undeclared facilities, and ensure they are filled by adapting old safeguards technologies, by developing and introducing new and novel safeguards teclmologies and/or by developing new procedures and protocols. Safeguards will also need to respond to anticipated emerging threats and to future, unanticipated threats. This will require strategic planning and cooperation among Member States and with the Agency. This paper will address challenges to IAEA safeguards and the technological possibilities and R&D strategies needed to meet those challenges in the context of the forty-year evolution of safeguards, including the ongoing transformation of safeguards by the Agency.

Large-Scale Data Challenges in Future Power Grids  

Science Conference Proceedings (OSTI)

This paper describes technical challenges in supporting large-scale real-time data analysis for future power grid systems and discusses various design options to address these challenges. Even though the existing U.S. power grid has served the nation remarkably well over the last 120 years, big changes are in the horizon. The widespread deployment of renewable generation, smart grid controls, energy storage, plug-in hybrids, and new conducting materials will require fundamental changes in the operational concepts and principal components. The whole system becomes highly dynamic and needs constant adjustments based on real time data. Even though millions of sensors such as phase measurement units (PMUs) and smart meters are being widely deployed, a data layer that can support this amount of data in real time is needed. Unlike the data fabric in cloud services, the data layer for smart grids must address some unique challenges. This layer must be scalable to support millions of sensors and a large number of diverse applications and still provide real time guarantees. Moreover, the system needs to be highly reliable and highly secure because the power grid is a critical piece of infrastructure. No existing systems can satisfy all the requirements at the same time. We examine various design options. In particular, we explore the special characteristics of power grid data to meet both scalability and quality of service requirements. Our initial prototype can improve performance by orders of magnitude over existing general-purpose systems. The prototype was demonstrated with several use cases from PNNL’s FPGI and was shown to be able to integrate huge amount of data from a large number of sensors and a diverse set of applications.

Steel industry of the future: Meeting the material challenges of the 21. century  

SciTech Connect

For over a century, the US steel industry has led the global market with advances in technology, product development, and marketing. Industry leaders recognize both the opportunities and challenges they face as they head into the 21st century, and that cooperative R and D is key to their success. In a unique partnership, steel industry leaders have teamed with the US Department of Energy`s Office of Industrial Technologies (OIT) to focus on innovative technologies that will help to strengthen the competitive position of the US steel industry and, at the same time, further important national goals. This industry-led partnership, the Steel Industry of the Future, promotes technologies that optimize the use of energy and materials in operation and reduce wastes and energy-related emissions. Led by the American Iron and Steel Institute (AISI) and the Steel Manufacturers Association (SMA), industry leaders began by developing a unified vision for the next 20 years: to provide high-quality, value-added products to a wide array of customers in an environmentally friendly, cost-effective manner, while leading the world in innovation and technology. Continued global leadership in materials markets will require the combined resources of industry, universities, and government laboratories. The steel industry vision provided a framework for the next step in the Industries of the Future process, the development of a technology roadmap designed to facilitate collaborative R and D on advanced processes and technologies for the steel industry.

The Office of Site Closure: Progress in the Face of Challenges  

SciTech Connect

The Office of Site Closure (OSC) was formed in November 1999 when the Department of Energy's (DOE's) Office of Environmental Management (EM) reorganized to focus specifically on site cleanup and closure. OSC's objective is to achieve safe and cost-effective cleanups and closures that are protective of our workers, the public, and the environment, now and in the future. Since its inception, OSC has focused on implementing a culture of safe closure, with emphasis in three primary areas: complete our responsibility for the Closure Sites Rocky Flats, Mound, Fernald, Ashtabula, and Weldon Spring; complete our responsibility for cleanup at sites where the DOE mission has been completed (examples include Battelle King Avenue and Battelle West Jefferson in Columbus, and General Atomics) or where other Departmental organizations have an ongoing mission (examples include the Brookhaven, Livermore, or Los Alamos National Laboratories, and the Nevada Test Site); and create a framework a nd develop specific business closure tools that will help sites close, such as guidance for and decisions on post-contract benefit liabilities, records retention, and Federal employee incentives for site closure. This paper discusses OSC's 2001 progress in achieving site cleanups, moving towards site closure, and developing specific business closure tools to support site closure. It describes the tools used to achieve progress towards cleanup and closure, such as the application of new technologies, changes in contracting approaches, and the development of agreements between sites and with host states. The paper also identifies upcoming challenges and explores options for how Headquarters and the sites can work together to address these challenges. Finally, it articulates OSC's new focus on oversight of Field Offices to ensure they have the systems in place to oversee contractor activities resulting in site cleanups and closures.

Future Automotive Aftertreatment Solutions: The 150°C Challenge Workshop Report  

SciTech Connect

With future fuel economy standards enacted, the U.S. automotive manufacturers (OEMs) are committed to pursuing a variety of high risk/highly efficient stoichiometric and lean combustion strategies to achieve superior performance. In recognition of this need, the U.S. Department of Energy (DOE) has partnered with domestic automotive manufacturers through U.S. DRIVE to develop these advanced technologies. However, before these advancements can be introduced into the U.S. market, they must also be able to meet increasingly stringent emissions requirements. A significant roadblock to this implementation is the inability of current catalyst and aftertreatment technologies to provide the required activity at the much lower exhaust temperatures that will accompany highly efficient combustion processes and powertrain strategies. Therefore, the goal of this workshop and report is to create a U.S. DRIVE emission control roadmap that will identify new materials and aftertreatment approaches that offer the potential for 90% conversion of emissions at low temperature (150°C) and are consistent with highly efficient combustion technologies currently under investigation within U.S. DRIVE Advanced Combustion and Emission Control (ACEC) programs.

Bioenergy crop models: Descriptions, data requirements and future challenges  

SciTech Connect

Field studies that address the production of lignocellulosic biomass as a potential source of renewable energy are making available critical information for the development, validation, and use of bioenergy crop models. A literature survey revealed that 14 models have been developed and validated for herbaceous and woody bioenergy crops, and for Crassulacean acid metabolism (CAM) crops adapted to arid lands. These models simulate field-scale production of biomass for switchgrass (ALMANAC, EPIC, and Agro-BGC), miscanthus (MISCANFOR, MISCANMOD, and WIMOVAC), sugarcane (APSIM, AUSCANE, and CANEGRO), and poplar and willow (SECRETS and 3PG). Two models are adaptations of dynamic global vegetation models and simulate biomass yields of miscanthus and sugarcane as plant function types at regional scales (Agro-IBIS and LPJmL). A model of biomass production in CAM plants has been developed (EPI), but lacks the sophistication of the other models. Except for CAM plants, all the models include representations of leaf area dynamics, radiation interception and utilization, biomass production, and partitioning of biomass to roots and shoots. A few of the models are capable of simulating soil water, nutrient, and carbon cycle processes, making them especially useful for assessing environmental consequences (e.g., erosion and nutrient losses) associated with the field-scale deployment of bioenergy crops. Similar to other process-based models, simulations are challenged by computing and data management issues and an integrated framework for model testing and inter-comparison is needed. Considerable work remains concerning the development of models for unconventional bioenergy crops like CAM plants, generation and distribution of high-quality field data for model development and validation, and development of an integrated framework for efficient execution of large-scale simulations for use in planning regional to global sustainable bioenergy production systems.

Future challenges and DOE/NNSA-JAEA cooperation for the development of advanced safeguards  

Science Conference Proceedings (OSTI)

The United States Department of Energy/National Nuclear Security Administration (DOE/NNSA) has been cooperating with Japan on nuclear safeguards for over thirty years. DOE/NNSA has collaborated with the Japan Atomic Energy Agency (JAEA) and its predecessors in addressing the need for innovative solutions to nuclear transparency and verification issues in one of the world's most advanced nuclear fuel cycle states. This collaboration includes over ninety activities that have involved nearly every facility in the JAEA complex and many national laboratories in the U.S. complex. The partnership has yielded new technologies and approaches that have benefited international safeguards not only in Japan, but around the world. The International Atomic Energy Agency uses a number of safeguards solutions developed under this collaboration to improve its inspection efforts in Japan and elsewhere. Japanese facilities serve as test beds for emerging safeguards technologies and are setting the trend for new nuclear energy and fuel cycle development worldwide. The collaboration continues to be an essential component of U.S. safeguards outreach and is integral to the DOE/NNSA's Next Generation Safeguards Initiative. In addition to fostering international safeguards development, the cooperation is an opportunity for U.S. scientists to work in facilities that have no analog in the United States, thus providing crucial real-life experience for and aiding development of the next generation of U.S. safeguards specialists. It is also an important element of promoting regional transparency thereby building confidence in the peaceful nature of nuclear programs in the region. The successes engendered by this partnership provide a strong basis for addressing future safeguards challenges, in Japan and elsewhere. This paper summarizes these challenges and the associated cooperative efforts that are either underway or anticipated.

Future Public Policy and Ethical Issues Facing the Agricultural and Microbial Genomics Sectors of the Biotechnology Industry: A Roundtable Discussion  

SciTech Connect

On September 12, 2003, the University of Maryland School of Law's Intellectual Property and Law & Health Care Programs jointly sponsored and convened a roundtable discussion on the future public policy and ethical issues that will likely face the agricultural and microbial genomics sectors of the biotechnology industry. As this industry has developed over the last two decades, societal concerns have moved from what were often local issues, e.g., the safety of laboratories where scientists conducted recombinant DNA research on transgenic microbes, animals and crops, to more global issues. These newer issues include intellectual property, international trade, risks of genetically engineered foods and microbes, bioterrorism, and marketing and labeling of new products sold worldwide. The fast paced nature of the biotechnology industry and its new developments often mean that legislators, regulators and society, in general, must play ''catch up'' in their efforts to understand the issues, the risks, and even the benefits, that may result from the industry's new ways of conducting research, new products, and novel methods of product marketing and distribution. The goal of the roundtable was to develop a short list of the most significant public policy and ethical issues that will emerge as a result of advances in these sectors of the biotechnology industry over the next five to six years. More concretely, by ''most significant'' the conveners meant the types of issues that would come to the attention of members of Congress or state legislators during this time frame and for which they would be better prepared if they had well researched and timely background information. A concomitant goal was to provide a set of focused issues for academic debate and scholarship so that policy makers, industry leaders and regulators would have the intellectual resources they need to better understand the issues and concerns at stake. The goal was not to provide answers to any of the issues or problems, simply to identify those topics that deserve our attention as a society. Some of the issues may benefit from legislation at the federal or state levels, others may be more appropriately addressed by the private sector. Participants at the roundtable included over a dozen experts in the areas of microbiology, intellectual property, agricultural biotechnology, microbial genomics, bioterrorism, economic development, biotechnology research, and bioethics. These experts came from federal and state government, industry and academia. The participants were asked to come to the roundtable with a written statement of the top three to five public policy/ ethical issues they viewed as most likely to be significant to the industry and to policy makers over the next several years.

Environmental and economic challenges to coal`s future in China  

SciTech Connect

Coal accounts for approximately 75% of China`s total primary energy consumption, and is by far the largest contributor to air pollution. The highest growth sector for coal consumption is the power sector, accounting for about 36 percent of total coal consumption in 1993. Over the 1994--2010 period most new, large power plants are expected to be coal-fired. Therefore, the availability and price of coal, as well as environmental constraints will be critical to foreign investors evaluating coal and power projects in China. The purpose of this paper is to provide useful technical, economic and environmental information and analysis on coal and the power sectors of China. The target audiences are potential investors and government energy and environmental policy people. This paper suggests a number of important energy and environmental policy issues that need to be addressed in a timely fashion in order to promote adequate levels of investment in coal and power developments in China. Although this paper highlights problems faced by foreign investors in coal and power, it is important to balance these problems against the large investment opportunities developing in these sectors.

Gas turbines face new challenges  

SciTech Connect

Gas turbines continue to increase the electric power generation market in both the peaking and the intermediate load categories. With the increase in unit size and operating efficiencies. capital costs per kilowatt are reduced. Clean fuels---gas, light oil, or alcohol-type fuel--are needed for the gas turbines. The most efficient method of power generation is now attained from gas turbines, but the shortage of clean fuels looms. Manufacturers are anticipating the availability of clean fuels and continue working on the development of high- pressure, high-temperature turbines. In the near-term, increased efficiency is sought by making use of the turbine exhaust heat. involving combined or regenerative cycles. (MCW)

Science Conference Proceedings (OSTI)

In this paper HPC architectural characteristics and their impact on application performance and scaling are investigated. Performance data gathered over several generations of very large HPC systems like: ASC Red Storm, ASC Purple, and a large InfiniBand cluster - Red Sky, are analyzed. As the number of cache coherent cores and number of NUMA domains at a compute node keeps increasing, we analyze their impact with a few simple benchmarks and several applications. We present bottlenecks and remedies examining production applications. We conclude with preliminary early-hardware performance data from the ASC Cielo, a petaFLOPS class future capability system.

Accelerators in our past, present, and future: A challenge to radiological protection in the twenty-first century  

SciTech Connect

The foundations of many of the subdisciplines of radiological protection laid in accelerator laboratories began with the invention of accelerators. This paper suggests that the discipline of accelerator radiological protection has played and will continue play a more significant part in our lives than is generally recognized. A brief review of some existing uses of accelerators by society is given, and a few probable future uses are described. These future applications will result in the exposure of accelerator (or {open_quotes}mixed{close_quotes}) radiation fields to an increased population. Consequently, what are perceived to be the rather specialized concerns of today`s accelerator health physicists will -- by necessity -- become of general interest to all health physicists.

Meeting future exhaust emissions standards using natural gas as a vehicle fuel: Lessons learned from the natural gas vehicle challenge '92  

DOE Green Energy (OSTI)

The Natural Gas Vehicle Challenge '92, organized by Argonne National Laboratory and sponsored by the US Department of Energy, the Energy, Mines, and Resources - Canada, the Society of Automotive Engineers, and many others, resulted in 20 varied approaches to the conversion of a gasoline-fueled, spark-ignited, internal combustion engine to dedicated natural gas use. Starting with a GMC Sierra 2500 pickup truck, donated by General Motors, teams of college and university student engineers strived to optimize Chevrolet V-8 engines operating on natural gas for improved emissions, fuel economy, performance, and advanced design features. This paper focuses on the results of the emission event, and compares engine mechanical configurations, engine management systems, catalyst configurations and locations, and approaches to fuel control and the relationship of these parameters to engine-out and tailpipe emissions of regulated exhaust constituents. Nine of the student-modified trucks passed the current levels of exhaust emission standards, and some exceeded the strictest future emissions standards envisioned by the US Environmental Protection Agency. Factors in achieving good emissions control using natural gas are summarized, and observations concerning necessary components of a successful emissions control strategy are presented.

Economics of Current and Future Biofuels  

Science Conference Proceedings (OSTI)

This work presents detailed comparative analysis on the production economics of both current and future biofuels, including ethanol, biodiesel, and butanol. Our objectives include demonstrating the impact of key parameters on the overall process economics (e.g., plant capacity, raw material pricing, and yield) and comparing how next-generation technologies and fuels will differ from today's technologies. The commercialized processes and corresponding economics presented here include corn-based ethanol, sugarcane-based ethanol, and soy-based biodiesel. While actual full-scale economic data are available for these processes, they have also been modeled using detailed process simulation. For future biofuel technologies, detailed techno-economic data exist for cellulosic ethanol from both biochemical and thermochemical conversion. In addition, similar techno-economic models have been created for n-butanol production based on publicly available literature data. Key technical and economic challenges facing all of these biofuels are discussed.

E-Print Network (OSTI)

Wireless Sensor networks (WSN) is an emerging technology and have great potential to be employed in critical situations like battlefields and commercial applications such as building, traffic surveillance, habitat monitoring and smart homes and many more scenarios. One of the major challenges wireless sensor networks face today is security. While the deployment of sensor nodes in an unattended environment makes the networks vulnerable to a variety of potential attacks, the inherent power and memory limitations of sensor nodes makes conventional security solutions unfeasible. The sensing technology combined with processing power and wireless communication makes it profitable for being exploited in great quantity in future. The wireless communication technology also acquires various types of security threats. This paper discusses a wide variety of attacks in WSN and their classification mechanisms and different securities available to handle them including the challenges faced.

Brookhaven will provide support for facility design and equipment specification. Once operational, we can provide monitoring of system performance and offer management and operations guidance. We also provide and maintain the control software for the FACE system, monitor performance and maintenance issues at affiliated FACE sites, and distribute solutions, work-arounds and lessons learned as appropriate. History The use of open-air gas releases to treat large scale plots has been undertaken since the 1970's. Hartwell Allen coined the name Free Air Carbon Dioxide Enrichment and the acronym FACE to describe a range of experiments that used open air releases to study the ecological effects of increasing atmospheric concentrations of carbon dioxide (Allen, 1992). Early designs used line source releases, and depended on consistent wind speed and direction or long term averaging to obtain a uniform treatment. In the 1980's circular systems with computer aided feedback control were designed to allow open-air exposures to sulfur dioxide, nitrogen oxides, and ozone (Mooi and van der Zalm 1985; McLeod et al 1985; Hendrey & Miglietta, 2006).

Science and Technology of Future Light Sources  

Science Conference Proceedings (OSTI)

Many of the important challenges facing humanity, including developing alternative sources of energy and improving health, are being addressed by advances that demand the improved understanding and control of matter. While the visualization, exploration, and manipulation of macroscopic matter have long been technological goals, scientific developments in the twentieth century have focused attention on understanding matter on the atomic scale through the underlying framework of quantum mechanics. Of special interest is matter that consists of natural or artificial nanoscale building blocks defined either by atomic structural arrangements or by electron or spin formations created by collective correlation effects. The essence of the challenge to the scientific community has been expressed in five grand challenges for directing matter and energy recently formulated by the Basic Energy Sciences Advisory Committee [1]. These challenges focus on increasing our understanding of, and ultimately control of, matter at the level of atoms, electrons. and spins, as illustrated in Figure 1.1, and serve the entire range of science from advanced materials to life sciences. Meeting these challenges will require new tools that extend our reach into regions of higher spatial, temporal, and energy resolution. X-rays with energies above 10 keV offer capabilities extending beyond the nanoworld shown in Figure 1.1 due to their ability to penetrate into optically opaque or thick objects. This opens the door to combining atomic level information from scattering studies with 3D information on longer length scales from real space imaging with a resolution approaching 1 nm. The investigation of multiple length scales is important in hierarchical structures, providing knowledge about function of living organisms, the atomistic origin of materials failure, the optimization of industrial synthesis, or the working of devices. Since the fundamental interaction that holds matter together is of electromagnetic origin, it is intuitively clear that electromagnetic radiation is the critical tool in the study of material properties. On the level of atoms, electrons, and spins, x-rays have proved especially valuable. Future advanced x-ray sources and instrumentation will extend the power of x-ray methods to reach greater spatial resolution, increased sensitivity, and unexplored temporal domains. The purpose of this document is threefold: (1) summarize scientific opportunities that are beyond the reach of today's x-ray sources and instrumentation; (2) summarize the requirements for advanced x-ray sources and instrumentation needed to realize these scientific opportunities, as well as potential methods of achieving them; and (3) outline the R&D required to establish the technical feasibility of these advanced x-ray sources and instrumentation.

Challenges in Data Intensive Analysis at Scientific Experimental User Facilities  

Science Conference Proceedings (OSTI)

Today's scientific challenges such as routes to a sustainable energy future, materials by design or biological and chemical environmental remediation methods, are complex problems that require the integration of a wide range of complementary expertise to be addressed successfully. Experimental and computational science research methods can hereby offer fundamental insights for their solution. Experimental facilities in particular can contribute through a large variety of investigative methods, which can span length scales from millions of kilometers (radar) to the sub-nucleus (LHC). These methods are used to probe structure, properties, and function of objects from single elements to whole communities. Hereby direct imaging techniques are a powerful means to develop an atomistic understanding of scientific issues. For example, the identification ofmechanisms associated with chemical, material, and biological transformations requires the direct observation of the reactions to build up an understanding of the atom-by-atom structural and chemical changes. Computational science can aid the planning of such experiments, correlate results, explain or predict the phenomena as they would be observed and thus aid their interpretation. Furthermore computational science can be essential for the investigation of phenomena that are difficult to observe due to their scale, reaction time or extreme conditions. Combining experimental and computational techniques provides scientists with the ability to research structures and processes at various levels of theory, e.g. providing molecular 'movies' of complex reactions that show bond breaking and reforming in natural time scales, along with the intermediate states to understand the mechanisms that govern the chemical transformations. This chapter will discuss the critical data intensive analysis challenges faced by the experimental science community at large scale and laboratory based facilities. The chapter will highlight current solutions and lay out perspectives for the future, such as methods to achieve real time analysis capabilities and the challenges and opportunities of data integration across experimental scales, levels of theory, and varying techniques.

Choices for A Brighter Future: Perspectives on Renewable Energy  

DOE Green Energy (OSTI)

The report discusses the perspectives on the evolving U.S. electricity future, the renewable electric technology portfolio, the regional outlook, and the opportunities to move forward. Renewables are at a critical juncture as the domestic electricity marketplace moves toward an era of increased choice and greater diversity. The cost and performance of these technologies have improved dramatically over the past decade, yet their market penetration has stalled as the power industry grapples with the implications of the emerging competitive marketplace. Renewable energy technologies already contribute to the global energy mix and are ready to make an even greater contribution in the future. However, the renewables industry faces critical market uncertainties, both domestically and internationally, as policy commitments to renewables at both the federal and state levels are being reshaped to match the emerging competitive marketplace. The energy decisions that we make, or fail to make, today will have long-lasting implications. We can act now to ensure that renewable energy will play a major role in meeting the challenges of the evolving energy future. We have the power to choose.

World energy: Building a sustainable future  

SciTech Connect

As the 20th century draws to a close, both individual countries and the world community face challenging problems related to the supply and use energy. These include local and regional environmental impacts, the prospect of global climate and sea level change associated with the greenhouse effect, and threats to international relations in connection with oil supply or nuclear proliferation. For developing countries, the financial cost of providing energy to provide basic needs and fuel economic development pose an additional burden. To assess the magnitude of future problems and the potential effectiveness of response strategies, it is important to understand how and why energy use has changed in the post and where it is heading. This requires study of the activities for which energy is used, and of how people and technology interact to provide the energy services that are desired. The authors and their colleagues have analyzed trends in energy use by sector for most of the world`s major energy-consuming countries. The approach we use considers three key elements in each sector: the level of activity, structural change, and energy intensity, which expresses the amount of energy used for various activities. At a disaggregated level, energy intensity is indicative of energy efficiency. But other factors besides technical efficiency also shape intensity.

Die Face Engineering based Springback Compensation Strategy and Implementation  

SciTech Connect

Springback or shape change has been one of the major challenges in sheet metal fabrication, particularly with increase application of high strength steel (HSS) and aluminum alloys in automotive stamping. Springback, an elastic material recovery after the unloading of stamping tools, causes variations and inconsistencies of final part dimensions. Minor or mild springback usually can be corrected in the re-strike process. Excessive springback must be corrected so the part will be produced within the given design tolerance and dimension. The commonly used Spring Forward approaches and shape compensations such as over-crown and over-bending are proven effective to alleviate excessive springback. To enhance these approaches, a new strategy of Die Face Engineering (DFE) based processing is proposed to quickly and easily to achieve the maximum allowable compensation using the under cut (or die lock) as the primary criteria. The implementation of the die face compensation through iterative FEA calculation, automatic surface mapping, projection and manual morphing are crucial to meet production environment requirements in terms of generating NC quality CAD surfaces of the compensated or morphed die face. In this paper, the strategy of the die face compensation with the consideration of the under cut criteria is presented. The implementation of various processes to enable user to perform the die face compensation task in a production environment is also discussed. Finally, two examples are shown to demonstrate the implementation of the proposed springback compensation scheme based on the combined CAE/CAD methodology.

Energy Efficiency Challenges in Heating Supply System of Turkmenistan and Potential Solutions  

E-Print Network (OSTI)

The poor condition and inefficient operation of the existing heat and hot water supply system in Turkmenistan is causing serious economic, social and environmental problems. Yet, the situation may very well change to the worse as increase of energy consumption is projected for near future. The country's commitment to reduce greenhouse gases emissions faces the challenge of ensuring that both the short- and long-term environmental impacts can be minimized while service levels of heat and hot water supply to the population are simultaneously improved. Despite the energy, economic, and environmental benefits of energy efficiency in Turkmenistan, little has been done to eliminate energy waste. Due historic legacy, there is a limited institutional capacity to increase energy efficiency. Achieving energy and environmental goals will require a basic institutional transformation. Gaps in polices and legislation in the area of energy efficiency and the lack capacity and institutional expertise in managing local, regional and national energy efficiency programs have to be addressed.

Bioenergy crop models: Descriptions, data requirements and future challenges  

SciTech Connect

Field studies that address the production of lignocellulosic biomass as a source of renewable energy provide critical data for the development of bioenergy crop models. A literature survey revealed that 14 models have been used for simulating bioenergy crops including herbaceous and woody bioenergy crops, and for crassulacean acid metabolism (CAM) crops. These models simulate field-scale production of biomass for switchgrass (ALMANAC, EPIC, and Agro-BGC), miscanthus (MISCANFOR, MISCANMOD, and WIMOVAC), sugarcane (APSIM, AUSCANE, and CANEGRO), and poplar and willow (SECRETS and 3PG). Two models are adaptations of dynamic global vegetation models and simulate biomass yields of miscanthus and sugarcane at regional scales (Agro-IBIS and LPJmL). Although it lacks the complexity of other bioenergy crop models, the environmental productivity index (EPI) is the only model used to estimate biomass production of CAM (Agave and Opuntia) plants. Except for the EPI model, all models include representations of leaf area dynamics, phenology, radiation interception and utilization, biomass production, and partitioning of biomass to roots and shoots. A few models simulate soil water, nutrient, and carbon cycle dynamics, making them especially useful for assessing the environmental consequences (e.g., erosion and nutrient losses) associated with the large-scale deployment of bioenergy crops. The rapid increase in use of models for energy crop simulation is encouraging; however, detailed information on the influence of climate, soils, and crop management practices on biomass production is scarce. Thus considerable work remains regarding the parameterization and validation of process-based models for bioenergy crops; generation and distribution of high-quality field data for model development and validation; and implementation of an integrated framework for efficient, high-resolution simulations of biomass production for use in planning sustainable bioenergy systems.

The r-process nucleosynthesis: Nuclear physics challenges  

SciTech Connect

About half of the nuclei heavier than iron observed in nature are produced by the socalled rapid neutron capture process, or r-process, of nucleosynthesis. The identification of the astrophysics site and the specific conditions in which the r-process takes place remains, however, one of the still-unsolved mysteries of modern astrophysics. Another underlying difficulty associated with our understanding of the r-process concerns the uncertainties in the predictions of nuclear properties for the few thousands exotic neutron-rich nuclei involved and for which essentially no experimental data exist. The present contribution emphasizes some important future challenges faced by nuclear physics in this problem, particularly in the determination of the nuclear structure properties of exotic neutron-rich nuclei as well as their radiative neutron capture rates and their fission probabilities. These quantities are particularly relevant to determine the composition of the matter resulting from the r-process. Their impact on the r-abundance distribution resulting from the decompression of neutron star matter is discussed.

Science and Technology of Future Light Sources: A White Paper  

Science Conference Proceedings (OSTI)

Many of the important challenges facing humanity, including developing alternative sources of energy and improving health, are being addressed by advances that demand the improved understanding and control of matter. While the visualization, exploration, and manipulation of macroscopic matter have long been technological goals, scientific developments in the twentieth century have focused attention on understanding matter on the atomic scale through the underlying framework of quantum mechanics. Of special interest is matter that consists of natural or artificial nanoscale building blocks defined either by atomic structural arrangements or by electron or spin formations created by collective correlation effects (Figure 1.1). The essence of the challenge to the scientific community has been expressed in five grand challenges for directing matter and energy recently formulated by the Basic Energy Sciences Advisory Committee [1]. These challenges focus on increasing our understanding of, and ultimately control of, matter at the level of atoms, electrons. and spins, as illustrated in Figure 1.1, and serve the entire range of science from advanced materials to life sciences. Meeting these challenges will require new tools that extend our reach into regions of higher spatial, temporal, and energy resolution. X-rays with energies above 10 keV offer capabilities extending beyond the nanoworld shown in Figure 1.1 due to their ability to penetrate into optically opaque or thick objects. This opens the door to combining atomic level information from scattering studies with 3D information on longer length scales from real space imaging with a resolution approaching 1 nm. The investigation of multiple length scales is important in hierarchical structures, providing knowledge about function of living organisms, the atomistic origin of materials failure, the optimization of industrial synthesis, or the working of devices. Since the fundamental interaction that holds matter together is of electromagnetic origin, it is intuitively clear that electromagnetic radiation is the critical tool in the study of material properties. On the level of atoms, electrons, and spins, x-rays have proved especially valuable. Future advanced x-ray sources and instrumentation will extend the power of x-ray methods to reach greater spatial resolution, increased sensitivity, and unexplored temporal domains. The purpose of this document is threefold: (1) summarize scientific opportunities that are beyond the reach of today's x-ray sources and instrumentation; (2) summarize the requirements for advanced x-ray sources and instrumentation needed to realize these scientific opportunities, as well as potential methods of achieving them; and (3) outline the R&D required to establish the technical feasibility of these advanced x-ray sources and instrumentation.

Renewable Electricity Futures Study. Executive Summary  

Science Conference Proceedings (OSTI)

The Renewable Electricity Futures (RE Futures) Study investigated the challenges and impacts of achieving very high renewable electricity generation levels in the contiguous United States by 2050. The analysis focused on the sufficiency of the geographically diverse U.S. renewable resources to meet electricity demand over future decades, the hourly operational characteristics of the U.S. grid with high levels of variable wind and solar generation, and the potential implications of deploying high levels of renewables in the future. RE Futures focused on technical aspects of high penetration of renewable electricity; it did not focus on how to achieve such a future through policy or other measures. Given the inherent uncertainties involved with analyzing alternative long-term energy futures as well as the multiple pathways that might be taken to achieve higher levels of renewable electricity supply, RE Futures explored a range of scenarios to investigate and compare the impacts of renewable electricity penetration levels (30%-90%), future technology performance improvements, potential constraints to renewable electricity development, and future electricity demand growth assumptions. RE Futures was led by the National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT).

Materials Challenges in Nuclear Energy  

SciTech Connect

Nuclear power currently provides about 13% of the worldwide electrical power, and has emerged as a reliable baseload source of electricity. A number of materials challenges must be successfully resolved for nuclear energy to continue to make further improvements in reliability, safety and economics. The operating environment for materials in current and proposed future nuclear energy systems is summarized, along with a description of materials used for the main operating components. Materials challenges associated with power uprates and extensions of the operating lifetimes of reactors are described. The three major materials challenges for the current and next generation of water-cooled fission reactors are centered on two structural materials aging degradation issues (corrosion and stress corrosion cracking of structural materials and neutron-induced embrittlement of reactor pressure vessels), along with improved fuel system reliability and accident tolerance issues. The major corrosion and stress corrosion cracking degradation mechanisms for light water reactors are reviewed. The materials degradation issues for the Zr alloy clad UO2 fuel system currently utilized in the majority of commercial nuclear power plants is discussed for normal and off-normal operating conditions. Looking to proposed future (Generation IV) fission and fusion energy systems, there are 5 key bulk radiation degradation effects (low temperature radiation hardening and embrittlement, radiation-induced and modified solute segregation and phase stability, irradiation creep, void swelling, and high temperature helium embrittlement) and a multitude of corrosion and stress corrosion cracking effects (including irradiation-assisted phenomena) that can have a major impact on the performance of structural materials.

Grand Challenges for Biological and Environmental Research: A Long-Term Vision  

SciTech Connect

The interactions and feedbacks among plants, animals, microbes, humans, and the environment ultimately form the world in which we live. This world is now facing challenges from a growing and increasingly affluent human population whose numbers and lifestyles are driving ever greater energy demand and impacting climate. These and other contributing factors will make energy and climate sustainability extremely difficult to achieve over the 20-year time horizon that is the focus of this report. Despite these severe challenges, there is optimism that deeper understanding of our environment will enable us to mitigate detrimental effects, while also harnessing biological and climate systems to ensure a sustainable energy future. This effort is advanced by scientific inquiries in the fields of atmospheric chemistry and physics, biology, ecology, and subsurface science - all made possible by computing. The Office of Biological and Environmental Research (BER) within the Department of Energy's (DOE) Office of Science has a long history of bringing together researchers from different disciplines to address critical national needs in determining the biological and environmental impacts of energy production and use, characterizing the interplay of climate and energy, and collaborating with other agencies and DOE programs to improve the world's most powerful climate models. BER science focuses on three distinct areas: (1) What are the roles of Earth system components (atmosphere, land, oceans, sea ice, and the biosphere) in determining climate? (2) How is the information stored in a genome translated into microbial, plant, and ecosystem processes that influence biofuel production, climate feedbacks, and the natural cycling of carbon? (3) What are the biological, geochemical, and physical forces that govern the behavior of Earth's subsurface environment? Ultimately, the goal of BER science is to support experimentation and modeling that can reliably predict the outcomes and behaviors of complex biological and environmental systems, leading to robust solutions for DOE missions and strategic goals. In March 2010, the Biological and Environmental Research Advisory Committee held the Grand Challenges for Biological and Environmental Research: A Long-Term Vision workshop to identify scientific opportunities and grand challenges for BER science in the coming decades and to develop an overall strategy for drafting a long-term vision for BER. Key workshop goals included: (1) Identifying the greatest scientific challenges in biology, climate, and the environment that DOE will face over a 20-year time horizon. (2) Describing how BER should be positioned to address those challenges. (3) Determining the new and innovative tools needed to advance BER science. (4) Suggesting how the workforce of the future should be trained in integrative system science. This report lays out grand research challenges for BER - in biological systems, climate, energy sustainability, computing, and education and workforce training - that can put society on a path to achieve the scientific evidence and predictive understanding needed to inform decision making and planning to address future energy needs, climate change, water availability, and land use.

Options for Kentucky's Energy Future  

Science Conference Proceedings (OSTI)

Three important imperatives are being pursued by the Commonwealth of Kentucky: ? Developing a viable economic future for the highly trained and experienced workforce and for the Paducah area that today supports, and is supported by, the operations of the US Department of Energy’s (DOE’s) Paducah Gaseous Diffusion Plant (PGDP). Currently, the PGDP is scheduled to be taken out of service in May, 2013. ? Restructuring the economic future for Kentucky’s most abundant indigenous resource and an important industry – the extraction and utilization of coal. The future of coal is being challenged by evolving and increasing requirements for its extraction and use, primarily from the perspective of environmental restrictions. Further, it is important that the economic value derived from this important resource for the Commonwealth, its people and its economy is commensurate with the risks involved. Over 70% of the extracted coal is exported from the Commonwealth and hence not used to directly expand the Commonwealth’s economy beyond the severance taxes on coal production. ? Ensuring a viable energy future for Kentucky to guarantee a continued reliable and affordable source of energy for its industries and people. Today, over 90% of Kentucky’s electricity is generated by burning coal with a delivered electric power price that is among the lowest in the United States. Anticipated increased environmental requirements necessitate looking at alternative forms of energy production, and in particular electricity generation.

Status and Future Developments in Large Accelerator Control Systems  

Science Conference Proceedings (OSTI)

Over the years, accelerator control systems have evolved from small hardwired systems to complex computer controlled systems with many types of graphical user interfaces and electronic data processing. Today's control systems often include multiple software layers, hundreds of distributed processors, and hundreds of thousands of lines of code. While it is clear that the next generation of accelerators will require much bigger control systems, they will also need better systems. Advances in technology will be needed to ensure the network bandwidth and CPU power can provide reasonable update rates and support the requisite timing systems. Beyond the scaling problem, next generation systems face additional challenges due to growing cyber security threats and the likelihood that some degree of remote development and operation will be required. With a large number of components, the need for high reliability increases and commercial solutions can play a key role towards this goal. Future control systems will operate more complex machines and need to present a well integrated, interoperable set of tools with a high degree of automation. Consistency of data presentation and exception handling will contribute to efficient operations. From the development perspective, engineers will need to provide integrated data management in the beginning of the project and build adaptive software components around a central data repository. This will make the system maintainable and ensure consistency throughout the inevitable changes during the machine lifetime. Additionally, such a large project will require professional project management and disciplined use of well-defined engineering processes. Distributed project teams will make the use of standards, formal requirements and design and configuration control vital. Success in building the control system of the future may hinge on how well we integrate commercial components and learn from best practices used in other industries.

Toward an energy surety future.  

SciTech Connect

Because of the inevitable depletion of fossil fuels and the corresponding release of carbon to the environment, the global energy future is complex. Some of the consequences may be politically and economically disruptive, and expensive to remedy. For the next several centuries, fuel requirements will increase with population, land use, and ecosystem degradation. Current or projected levels of aggregated energy resource use will not sustain civilization as we know it beyond a few more generations. At the same time, issues of energy security, reliability, sustainability, recoverability, and safety need attention. We supply a top-down, qualitative model--the surety model--to balance expenditures of limited resources to assure success while at the same time avoiding catastrophic failure. Looking at U.S. energy challenges from a surety perspective offers new insights on possible strategies for developing solutions to challenges. The energy surety model with its focus on the attributes of security and sustainability could be extrapolated into a global energy system using a more comprehensive energy surety model than that used here. In fact, the success of the energy surety strategy ultimately requires a more global perspective. We use a 200 year time frame for sustainability because extending farther into the future would almost certainly miss the advent and perfection of new technologies or changing needs of society.

The geothermal partnership: Industry, utilities, and government meeting the challenges of the 90's  

DOE Green Energy (OSTI)

Each year the Geothermal Division of the US Department of Energy conducts an in-depth review of its entire geothermal R D program. The conference serves several purposes: a status report on current R D activities, an assessment of progress and problems, a review of management issues, and a technology transfer opportunity between DOE and the US geothermal community. This year's conference, Program Review IX, was held in San Francisco on March 19--21, 1991. The theme of this review was The Geothermal Partnership -- Industry, Utilities, and Government Meeting the Challenges of the 90's.'' The importance of this partnership has increased markedly as demands for improved technology must be balanced with available research resources. By working cooperatively, the geothermal community, including industry, utilities, DOE, and other state and federal agencies, can more effectively address common research needs. The challenge currently facing the geothermal partnership is to strengthen the bonds that ultimately will enhance opportunities for future development of geothermal resources. Program Review IX consisted of eight sessions including an opening session. The seven technical sessions included presentations by the relevant field researchers covering DOE-sponsored R D in hydrothermal, hot dry rock, and geopressured energy and the progress associated with the Long Valley Exploratory Well. Individual papers have been cataloged separately.

Multiphysics Simulations: Challenges and Opportunities  

Science Conference Proceedings (OSTI)

We consider multiphysics applications from algorithmic and architectural perspectives, where "algorithmic" includes both mathematical analysis and computational complexity, and "architectural" includes both software and hardware environments. Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities.

A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities.

Nuclear Energy - Hydrogen Production - Fuel Cell: A Road Towards Future China's Sustainable Energy Strategy  

Science Conference Proceedings (OSTI)

Sustainable development of Chinese economy in 21. century will mainly rely on self-supply of clean energy with indigenous natural resources. The burden of current coal-dominant energy mix and the environmental stress due to energy consumptions has led nuclear power to be an indispensable choice for further expanding electricity generation capacity in China and for reducing greenhouse effect gases emission. The application of nuclear energy in producing substitutive fuels for road transportation vehicles will also be of importance in future China's sustainable energy strategy. This paper illustrates the current status of China's energy supply and the energy demand required for establishing a harmonic and prosperous society in China. In fact China's energy market faces following three major challenges, namely (1) gaps between energy supply and demand; (2) low efficiency in energy utilization, and (3) severe environmental pollution. This study emphasizes that China should implement sustainable energy development policy and pay great attention to the construction of energy saving recycle economy. Based on current forecast, the nuclear energy development in China will encounter a high-speed track. The demand for crude oil will reach 400-450 million tons in 2020 in which Chinese indigenous production will remain 180 million tons. The increase of the expected crude oil will be about 150 million tons on the basis of 117 million tons of imported oil in 2004 with the time span of 15 years. This demand increase of crude oil certainly will influence China's energy supply security and to find the substitution will be a big challenge to Chinese energy industry. This study illustrates an analysis of the market demands to future hydrogen economy of China. Based on current status of technology development of HTGR in China, this study describes a road of hydrogen production with nuclear energy. The possible technology choices in relation to a number of types of nuclear reactors are compared and assessed. The analysis shows that only high temperature gas cooled reactor (HTGR) and sodium fast breed reactor might be available in China in 2020 for hydrogen production. Further development of very high temperature gas cooled reactor (VHTR) and gas-cooled fast reactor (GCFR) is necessary to ensure China's future capability of hydrogen production with nuclear energy as the primary energy. It is obvious that hydrogen production with high efficient nuclear energy will be a suitable strategic technology road, through which future clean vehicles burning hydrogen fuel cells will become dominant in future Chinese transportation industry and will play sound role in ensuring future energy security of China and the sustainable prosperity of Chinese people.

The United States after the great recession: the challenge of sustainable growth  

SciTech Connect

The paper outlines the strengths and weaknesses of the U.S. economic growth model, assesses its’ ability to respond to the key economic, environmental and social challenges currently facing the U.S. and proposes policies that if adopted would move the U.S. onto a more sustainable growth path. The paper provides scenarios of projected future growth trajectories, as well as recommendations for specific policies in key areas: employment, infrastructure, energy and fiscal rebalancing. To reach this goal this paper focuses on four areas for action: Increasing employment, which is the most urgent priority to accelerate recovery from the Great Recession, while addressing underlying structural issues that have led to a decade of poor economic outcomes for most citizens; Investing in the future, as the key marker of whether the United States is prepared to make farsighted decisions to improve education, build new infrastructure and increase innovation; Maximizing an increased energy endowment in a way that grows the economy, while reinforcing the trend towards reducing resource demand and reducing greenhouse gas emissions; and, Fiscal rebalancing, where the United States must insulate economic recovery from the process of fiscal reform while reducing and stabilizing debt over the long term. Finally, we argue that President Obama can re-energize America’s global leadership if he builds on a platform of domestic actions that enhance the sustainability of America’s society and economy.

Primer on electricity futures and other derivatives  

SciTech Connect

Increased competition in bulk power and retail electricity markets is likely to lower electricity prices, but will also result in greater price volatility as the industry moves away from administratively determined, cost-based rates and encourages market-driven prices. Price volatility introduces new risks for generators, consumers, and marketers. Electricity futures and other derivatives can help each of these market participants manage, or hedge, price risks in a competitive electricity market. Futures contracts are legally binding and negotiable contracts that call for the future delivery of a commodity. In most cases, physical delivery does not take place, and the futures contract is closed by buying or selling a futures contract on or near the delivery date. Other electric rate derivatives include options, price swaps, basis swaps, and forward contracts. This report is intended as a primer for public utility commissioners and their staff on futures and other financial instruments used to manage price risks. The report also explores some of the difficult choices facing regulators as they attempt to develop policies in this area.

Hard truths: facing the hard truths about energy. A comprehensive view to 2030 of global oil and natural gas  

Science Conference Proceedings (OSTI)

In response to the questions posed by the US Secretary of Energy in October 2005, the National Petroleum Council conducted a comprehensive study considering the future of oil and natural gas to 2030 in the context of the global energy system. The Council proposed five core strategies to assist markets in meeting the energy challenges to 2030 and beyond. All five strategies are essential; there is no single, easy solution to the multiple challenges we face. However, we are confident that the prompt adoption of these strategies, along with a sustained commitment to implementation, will promote U.S. competitiveness by balancing economic, security, and environmental goals. The United States must: Moderate the growing demand for energy by increasing efficiency of transportation, residential, commercial, and industrial uses; Expand and diversify production from clean coal, nuclear, biomass, other renewables, and unconventional oil and gas; moderate the decline of conventional domestic oil and gas production; and increase access for development of new resources; Integrate energy policy into trade, economic, environmental, security, and foreign policies; strengthen global energy trade and investment; and broaden dialogue with both producing and consuming nations to improve global energy security; Enhance science and engineering capabilities and create long-term opportunities for research and development in all phases of the energy supply and demand system; and Develop the legal and regulatory framework to enable carbon capture and sequestration. In addition, as policymakers consider options to reduce carbon dioxide emissions, provide an effective global framework for carbon management, including establishment of a transparent, predictable, economy-wide cost for carbon dioxide emissions. The report, details findings and recommendations based on comprehensive analyses developed by the study teams. 5 apps.

Nuclear nonproliferation and safety: Challenges facing the International Atomic Energy Agency  

SciTech Connect

The Chairman of the Senate Committee on Govermental Affairs asked the United States General Accounting Office (GAO) to review the safeguards and nuclear power plant safety programs of the International Atomic Energy Agency (IAEA). This report examines (1) the effectiveness of IAEA`s safeguards program and the adequacy of program funding, (2) the management of U.S. technical assistance to the IAEA`s safeguards program, and (3) the effectiveness of IAEA`s program for advising United Nations (UN) member states about nuclear power plant safety and the adequacy of program funding. Under its statute and the Treaty on the Non-Proliferation of Nuclear Weapons, IAEA is mandated to administer safeguards to detect diversions of significant quantities of nuclear material from peaceful uses. Because of limits on budget growth and unpaid contributions, IAEA has had difficulty funding the safeguards program. IAEA also conducts inspections of facilities or locations containing declared nuclear material, and manages a program for reviewing the operational safety of designated nuclear power plants. The U.S. technical assistance program for IAEA safeguards, overseen by an interagency coordinating committee, has enhanced the agency`s inspection capabilities, however, some weaknesses still exist. Despite financial limitations, IAEA is meeting its basic safety advisory responsibilities for advising UN member states on nuclear safety and providing requested safety services. However, IAEA`s program for reviewing the operational safety of nuclear power plants has not been fully effective because the program is voluntary and UN member states have not requested IAEA`s review of all nuclear reactors with serious problems. GAO believes that IAEA should have more discretion in selecting reactors for review.

International ESCO business opportunities and challenges: a Japanese case study  

SciTech Connect

Recently, US energy service companies (ESCOs) have begun to actively explore markets outside the US. Despite the needs of many countries for ESCO involvement, ESCOs face many challenges (i.e., marketing, financial, institutional, political and cultural barriers). Consequently, most of these firms pursue international project opportunities very selectively due to the costs and risks associated with project development. Despite these barriers, some ESCOs view international work as a strategic expansion of their business, assuming that there will be adequate business in the future to repay them for their initial investment. In this paper, the authors present the findings from a recently completed study on the proposed development of an ESCO industry in Japan. The study was based on four sources of information: (1) a review of the published and unpublished literature on ESCOs; (2) interviews with 26 ESCOs in the US, the US Department of Energy, and the National Association of Energy Service Companies (NAESCO); (3) ESCO presentations at the October 1996 NAESCO meeting; and (4) informal discussions with ESCO experts in the US. They believe that the lessons learned in this study can be transferred or applied to other countries interested in developing an ESCO industry. While energy prices have remained relatively stable over the last several years in Japan and energy capacity is not perceived as a near-term problem, other ``market drivers`` necessary for the emergence of a successful and vibrant ESCO industry exist in Japan. Despite the presence of these market drivers, significant barriers to the successful development of an ESCO industry exist in Japan.

Osadciw, “Fusion for Component based Face Recognition  

E-Print Network (OSTI)

Abstract — This paper proposes a practical way to realize the diversity in face recognition system for performance improvement by fusing the classification results from the components (characteristic regions such as eyes, nose and mouth) and from the whole face image, instead of concatenating the face feature and the modular features for a single classifier. The extracted sub-images are not totally independent from the face image, but the experiments show that the fused result is improved from the recognition result based on the face or components alone. The fusion is implemented and compared at both score level and decision level. Communication resources are preserved between the sensor and fusion point in decision level fusion at the expense of performance, and the selection of which fusion scheme to use depends on the system resources and performance requirement. In the same way that the face images are used to construct the Eigenface [1] or DFLDA [2] feature space for recognition, the componentsare used to construct the feature spaces for each part on their own. Four components are considered in the simulation: eyes, nose, moth and forehead to derive similarity scores for four classifiers. Score level fusion sums the scores from each classifier to make the final decision as shown in Figure 1. The summation could be weighted according to the relative accuracy and importance of each individual classifier [3], [4]. Score level fusion needs to transmit the real number scores from the classifiers to the fusion center. This takes more transmission recourses than the categorical ranking decisions from the classifiers, but the score provides more information. Decision level fusion utilizes majority voting to fuse the results from each classifier as shown in Figure 2. Decision level fusion greatly reduces bandwidth needs on transmission. However, once the decision is made at each classifier based on the scores, the information on their relative degrees of similarity is lost preventing its use in the final decision. As shown in Table I, the classifiers based on the components are weaker than the classifier based on the face. Variations based on different weighting of the five classifiers are tried.

Banff Challenge 2  

SciTech Connect

Experimental particle physics collaborations constantly seek newer and better ideas for improving the sensitivity of their searches for new particles and phenomena. Statistical techniques are the last step in interpreting the results of an experiment; they are used to make discoveries (hypothesis testing), and to measure parameters (point estimation). They are also used in the first step - experiment and analysis design. Banff Challenge 2 asks participants to test their methods of discovering hidden signals in simulated datasets and of measuring the properties of these signals. The Challenge problems are described, and the performances of the submitted entries is summarized, for datasets with and without simulated signals present.

Scientific and Computational Challenges of the Fusion Simulation Program (FSP)  

SciTech Connect

This paper highlights the scientific and computational challenges facing the Fusion Simulation Program (FSP) a major national initiative in the United States with the primary objective being to enable scientific discovery of important new plasma phenomena with associated understanding that emerges only upon integration. This requires developing a predictive integrated simulation capability for magnetically-confined fusion plasmas that are properly validated against experiments in regimes relevant for producing practical fusion energy. It is expected to provide a suite of advanced modeling tools for reliably predicting fusion device behavior with comprehensive and targeted science-based simulations of nonlinearly-coupled phenomena in the core plasma, edge plasma, and wall region on time and space scales required for fusion energy production. As such, it will strive to embody the most current theoretical and experimental understanding of magnetic fusion plasmas and to provide a living framework for the simulation of such plasmas as the associated physics understanding continues to advance over the next several decades. Substantive progress on answering the outstanding scientific questions in the field will drive the FSP toward its ultimate goal of developing the ability to predict the behavior of plasma discharges in toroidal magnetic fusion devices with high physics fidelity on all relevant time and space scales. From a computational perspective, this will demand computing resources in the petascale range and beyond together with the associated multi-core algorithmic formulation needed to address burning plasma issues relevant to ITER - a multibillion dollar collaborative experiment involving seven international partners representing over half the world's population. Even more powerful exascale platforms will be needed to meet the future challenges of designing a demonstration fusion reactor (DEMO). Analogous to other major applied physics modeling projects (e.g., Climate Modeling), the FSP will need to develop software in close collaboration with computers scientists and applied mathematicians and validated against experimental data from tokamaks around the world. Specific examples of expected advances needed to enable such a comprehensive integrated modeling capability and possible "co-design" approaches will be discussed. __________________________________________________

Experimental challenges of the N* program  

SciTech Connect

The first challenge faced in investigating the strong interaction from partially explored, where meson-cloud degrees of freedom dominate, to still unexplored distance scales, where the dressed-quark contributions are the dominating degrees of freedom, is to find an experiment that allows to measure observables that are probing this evolving nonperturbative QCD regime over the full range. Baryon spectroscopy can establish more sensitively, and in an almost model-independent way, nucleon excitation and non-resonant reaction amplitudes by complete measurements of pseudo-scalar meson photoproduction off nucleons. Elastic and transition form factors can then trace this evolution by measurements of elastic electron scattering and exclusive single-meson and double-pion electroproduction cross sections off the nucleon that will be extended to higher momentum transfers with the energy-upgraded CEBAF beam at JLab to study the dressed quark degrees of freedom, where their strong interaction is responsible for the ground and excited nucleon state formations. After establishing unprecedented high-precision data, the immanent next challenge is a high-quality analysis to extract these relevant electrocoupling parameters for various resonances that then can be compared to state of the art models and QCD-based calculations. Recent results demonstrate the status of the analysis and pinpoint further challenges, including those to establish QCD-based results directly from the experimental data.

Regularized Robust Coding for Face Recognition  

E-Print Network (OSTI)

Recently the sparse representation based classification (SRC) has been proposed for robust face recognition (FR). In SRC, the testing image is coded as a sparse linear combination of the training samples, and the representation fidelity is measured by the l2-norm or l1-norm of the coding residual. Such a sparse coding model assumes that the coding residual follows Gaussian or Laplacian distribution, which may not be effective enough to describe the coding residual in practical FR systems. Meanwhile, the sparsity constraint on the coding coefficients makes SRC's computational cost very high. In this paper, we propose a new face coding model, namely regularized robust coding (RRC), which could robustly regress a given signal with regularized regression coefficients. By assuming that the coding residual and the coding coefficient are respectively independent and identically distributed, the RRC seeks for a maximum a posterior solution of the coding problem. An iteratively reweighted regularized robust coding (IR...

Future fuels from Montana  

SciTech Connect

To make America less dependent on foreign oil, Montana Governor Brain Schweitzer pushes for investment in synfuel technology. He advocates coal as the 'new fuel' for cars and believes synfuels from coal can bridge the gap between the petroleum economy of the past and the hydrogen economy of the future. He is pushing for a 'Future Fuels' project to form a public-private partnership to build 20 coal conversion, synfuel manufacturing plants. This could contribute to making the USA energy self-sufficient, more quickly than the FutureGen project, he believes.

Electric Powertrains: Opportunities and Challenges  

E-Print Network (OSTI)

Managing impending environmental and energy challenges in the transport sector requires a dramatic reduction in both the petroleum consumption and greenhouse gas (GHG) emissions of in-use vehicles. This study quantifies the potential of electric and hybrid-electric powertrains, such as gasoline hybrid-electric vehicles (HEVs), plug-in hybrid vehicles (PHEVs), fuel-cell vehicles (FCVs), and battery-electric vehicles (BEVs), to offer such reductions. The evolution of key enabling technologies was evaluated over a 30 year time horizon. These results were integrated with software simulations to model vehicle performance and tank-towheel energy consumption; the technology evaluation was also used to estimate costs. Well-towheel energy and GHG emissions of future vehicle technologies were estimated by integrating the vehicle technology evaluation with assessments of different fuel pathways. While electric powertrains can reduce or eliminate the transport sector’s reliance on petroleum, their GHG and energy reduction potential are constrained by continued reliance on fossil-fuels for producing electricity and hydrogen. In addition, constraints on growth of new vehicle technologies and slow rates of fleet turnover imply that these technologies take decades to effect meaningful change. As such, they do not offer a silver bullet: new technologies must be

Challenges in Implementing Methodologies for Nonproliferation Assessments  

Science Conference Proceedings (OSTI)

A handful of models for explaining and predicting States’ development of nuclear weapons programs have been proposed since the 1970s. Despite the array of techno-social variables and computational concepts employed in these models, no model has yet been established as an agreed-upon standard. Likewise, the International Atomic Energy Agency (IAEA)—one of the main institutions evaluating social, political, and technological information for assessments of States’ current nuclear capabilities—uses only a qualitative framework by which to evaluate such information to assess the correctness and completeness of a State’s declaration. In this paper, analysts familiar with both the development of techno-social modelling and the IAEA’s implementation of a safeguards system that is information driven discuss the challenges faced in the development, implementation, and evaluation of models and methodologies for nonproliferation assessments, based on experiences at Pacific Northwest National Laboratory (PNNL) and the IAEA.

Introduction to the HPC Challenge Benchmark Suite  

Science Conference Proceedings (OSTI)

The HPC Challenge benchmark suite has been released by the DARPA HPCS program to help define the performance boundaries of future Petascale computing systems. HPC Challenge is a suite of tests that examine the performance of HPC architectures using kernels with memory access patterns more challenging than those of the High Performance Linpack (HPL) benchmark used in the Top500 list. Thus, the suite is designed to augment the Top500 list, providing benchmarks that bound the performance of many real applications as a function of memory access characteristics e.g., spatial and temporal locality, and providing a framework for including additional tests. In particular, the suite is composed of several well known computational kernels (STREAM, HPL, matrix multiply--DGEMM, parallel matrix transpose--PTRANS, FFT, RandomAccess, and bandwidth/latency tests--b{sub eff}) that attempt to span high and low spatial and temporal locality space. By design, the HPC Challenge tests are scalable with the size of data sets being a function of the largest HPL matrix for the tested system.

Future land use plan  

Science Conference Proceedings (OSTI)

The US Department of Energy`s (DOE) changing mission, coupled with the need to apply appropriate cleanup standards for current and future environmental restoration, prompted the need for a process to determine preferred Future Land Uses for DOE-owned sites. DOE began the ``Future Land Use`` initiative in 1994 to ensure that its cleanup efforts reflect the surrounding communities` interests in future land use. This plan presents the results of a study of stakeholder-preferred future land uses for the Brookhaven National Laboratory (BNL), located in central Long Island, New York. The plan gives the Laboratory`s view of its future development over the next 20 years, as well as land uses preferred by the community were BNL ever to cease operations as a national laboratory (the post-BNL scenario). The plan provides an overview of the physical features of the site including its history, topography, geology/hydrogeology, biological inventory, floodplains, wetlands, climate, and atmosphere. Utility systems and current environmental operations are described including waste management, waste water treatment, hazardous waste management, refuse disposal and ground water management. To complement the physical descriptions of the site, demographics are discussed, including overviews of the surrounding areas, laboratory population, and economic and non-economic impacts.

A massive modernization and restructuring program is under way in the refining sector of Russia and other former Soviet republics. Economic reforms and resulting economic dislocation following the collapse of the Soviet Union has left refineries in the region grappling with a steep decline and changes in product demand. At the same time, rising oil prices and an aging, dilapidated infrastructure promise a massive shakeout. Even as many refineries in the former Soviet Union (FSU) face possible closure because they are running at a fraction of capacity, a host of revamps, expansions, and grass roots refineries are planned or under way. The paper discusses plans.

Abstract. The architecture of Blue Martini Software’s e-commerce suite has supported data collection, transformation, and data mining since its inception. With clickstreams being collected at the application-server layer, high-level events being logged, and data automatically transformed into a data warehouse using meta-data, common problems plaguing data mining using weblogs (e.g. sessionization and conflating multi-sourced data) were obviated, thus allowing us to concentrate on actual data mining goals. We briefly review the architecture and discuss many lessons learned over the last four years and the challenges still facing us. The lessons and challenges are presented across two dimensions: business-level vs. technical, and throughout the data mining lifecycle stages of data collection, data warehouse construction, business intelligence, and deployment. The lessons and challenges are more widely applicable to data mining domains outside retail e-commerce. Keywords: Data mining, data analysis, business intelligence, web analytics, web mining, OLAP,

Solar PV Project Financing: Regulatory and Legislative Challenges for Third-Party PPA System Owners  

DOE Green Energy (OSTI)

Residential and commercial end users of electricity who want to generate electricity using on-site solar photovoltaic (PV) systems face challenging initial and O&M costs. The third-party ownership power purchase agreement (PPA) finance model addresses these and other challenges. It allows developers to build and own PV systems on customers? properties and sell power back to customers. However, third-party electricity sales commonly face five regulatory challenges. The first three challenges involve legislative or regulatory definitions of electric utilities, power generation equipment, and providers of electric services. These definitions may compel third-party owners of solar PV systems to comply with regulations that may be cost prohibitive. Third-party owners face an additional challenge if they may not net meter, a practice that provides significant financial incentive to owning solar PV systems. Finally, municipalities and cooperatives worry about the regulatory implications of allowing an entity to sell electricity within their service territories. This paper summarizes these challenges, when they occur, and how they have been addressed in five states. This paper also presents alternative to the third-party ownership PPA finance model, including solar leases, contractual intermediaries, standardized contract language, federal investment tax credits, clean renewable energy bonds, and waived monopoly powers.

CHALLENGE MEASUREMENTS FOR AUTHENTICATION  

Science Conference Proceedings (OSTI)

Authentication of systems with an information barrier that protects sensitive information is difficult; in particular, the information barrier can allow a hidden switch to be implemented by the system fabricator and operator. The hidden switch is the operator’s ability to subvert the measurement system and force it to produce a desired and false result. It is usually discussed in the context of an attribute measurement in which a faked item is presented in place of a real item regulated by an agreement, with the driving motivation being the ability to preserve a stock of valuable items. In simple terms, the hidden switch enables a shell game with assets, and the information barrier protects the switch. This presentation outlines challenge measurements that could be used to detect the implementation of a hidden switch and assist the authentication process.

Solving the problems facing the electric utilities  

SciTech Connect

The dimensions of the current problems of attracting capital for utilities investment, of achieving more efficient utilization of capacity, of siting and construction of new power plants, and of utilities receiving a return on their investment large enough to enable them to continue their service to American consumers are examined. Federal actions that are being taken to help get the utilities out of their current state of malaise are described. The author concludes that positive electric power load management, through a system of cost-based pricing incentives and load controls, can achieve a balanced future both for total electricity usage and for peak demand. This would minimize the consumption of scarce fossil fuels in electricity generation, moderate the future need for construction of new capacity, improve utility revenues, and eventually reduce the need for rate increases to maintain utility viability. The FEA feels that is a reasonable, attainable objective for substantial electrification of the economy beyond 1985. (MCW)

E-Print Network (OSTI)

In this paper, I briefly sketch how the New Economy forces of globalization and technology have affected Wisconsin’s manufacturing in the recent past, and I note the challenges these forces will pose in the future. The first step in recognizing these challenges is to understand if there really is such a thing as a New Economy, and if so, whether it has openings into which a set of Old Economy industries can be plugged in order to become a part of it. Specifically, can a state like Wisconsin use its traditional industries as stepping stones to join the New Economy and enjoy its benefits? My view is that it can because in many instances it is the Old Economy that provides the market for New Economy products. While Wisconsin will face difficulties in overcoming the challenges posed to it by the New Economy, Wisconsin is better positioned than many states to use its Old Economy industries to meet those challenges. I give most of my attention to the large and volatile machinery industry, which provides over half of Wisconsin’s exports and which is the sector most sensitive to export fluctuations and import competition. I describe what Southeast Wisconsin might be like if it remained the hub of some Old Economy machinery industries, but operated in the New Economy mode of entrepreneurial venture capitalism while developing new technologies for its traditional industries.

Field Research Challenge Site  

DOE Green Energy (OSTI)

Previous experiments at the Rifle, Colorado Integrated Field Research Challenge (IFRC) site demonstrated that field-scale addition of acetate to groundwater reduced the ambient soluble uranium concentration. In this report, sediment samples collected before and after acetate field addition were used to assess the active microbes via {sup 13}C acetate stable isotope probing on 3 phases [coarse sand, fines (8-approximately 150 {micro}m), groundwater (0.2-8 {micro}m)] over a 24-day time frame. TRFLP results generally indicated a stronger signal in {sup 13}C-DNA in the 'fines' fraction compared to the sand and groundwater. Before the field-scale acetate addition, a Geobacter-like group primarily synthesized {sup 13}C-DNA in the groundwater phase, an alpha Proteobacterium primarily grew on the fines/sands, and an Acinetobacter sp. and Decholoromonas-like OTU utilized much of the {sup 13}C acetate in both groundwater and particle-associated phases. At the termination of the field-scale acetate addition, the Geobacter-like species was active on the solid phases rather than the groundwater, while the other bacterial groups had very reduced newly synthesized DNA signal. These findings will help to delineate the acetate utilization patterns of bacteria in the field and can lead to improved methods for stimulating distinct microbial populations in situ.

Challenging the challenge: handling data in the Gigabit/s range, to be published  

E-Print Network (OSTI)

The ALICE experiment at CERN will propose unprecedented requirements for event building and data recording. New technologies will be adopted as well as ad-hoc frameworks, from the acquisition of experimental data up to the transfer onto permanent media and its later access. These issues justify a careful, in-depth planning and preparation. The ALICE Data Challenge is a very important step of this development process where simulated detector data is moved from dummy data sources up to the recording media using processing elements and data-paths as realistic as possible. We will review herein the current status of past, present and future ALICE Data Challenges, with particular reference to the sessions held in 2002 when – for the first time – streams worth one week of ALICE data were recorded onto tape media at sustained rates exceeding 300 MB/s. 1.

Mountain Home Air Force Base, Idaho Geothermal Resource Assessment and Future Recommendations  

SciTech Connect

The U.S. Air Force is facing a number of challenges as it moves into the future, one of the biggest being how to provide safe and secure energy to support base operations. A team of scientists and engineers met at Mountain Home Air Force Base in early 2011 near Boise, Idaho, to discuss the possibility of exploring for geothermal resources under the base. The team identified that there was a reasonable potential for geothermal resources based on data from an existing well. In addition, a regional gravity map helped identify several possible locations for drilling a new well. The team identified several possible sources of funding for this well—the most logical being to use U.S. Department of Energy funds to drill the upper half of the well and U.S. Air Force funds to drill the bottom half of the well. The well was designed as a slimhole well in accordance with State of Idaho Department of Water Resources rules and regulations. Drilling operations commenced at the Mountain Home site in July of 2011 and were completed in January of 2012. Temperatures increased gradually, especially below a depth of 2000 ft. Temperatures increased more rapidly below a depth of 5500 ft. The bottom of the well is at 5976 ft, where a temperature of about 140°C was recorded. The well flowed artesian from a depth below 5600 ft, until it was plugged off with drilling mud. Core samples were collected from the well and are being analyzed to help understand permeability at depth. Additional tests using a televiewer system will be run to evaluate orientation and directions at fractures, especially in the production zone. A final report on the well exploitation will be forthcoming later this year. The Air Force will use it to evaluate the geothermal resource potential for future private development options at Mountain Home Air Force Base. In conclusion, Recommendation for follow-up efforts include the following:

Microchannel cooling of face down bounded chips  

DOE Patents (OSTI)

The present invention relates to cooling high power integrated circuits; and particularly to microchannel cooling of integrated circuits bonded face down on circuit boards, such as by flip-chip bonding. Microchannel cooling is applied to flip-chip bonded integrated circuits, in a manner which maintains the advantages of flip-chip bonds, while overcoming the difficulties encountered in cooling the chips. The technique is suited to either multichip integrated circuit boards in a plane, or to stacks of circuit boards in a three dimensional interconnect structure. Integrated circuit chips are mounted on a circuit board using flip-chip or control collapse bonds. A microchannel structure is essentially permanently coupled with the back of the chip. A coolant delivery manifold delivers coolant to the microchannel structure, and a seal consisting of a compressible elastomer is provided between the coolant delivery manifold and the microchannel structure. The integrated circuit chip and microchannel structure are connected together to form a replaceable integrated circuit module which can be easily decoupled from the coolant delivery manifold and the circuit board. The coolant supply manifolds may be disposed between the circuit boards in a stack and coupled to supplies of coolant through a side of the stack.

The Surface of Acceptability in Virtual Faces  

E-Print Network (OSTI)

This paper explores the surface properties of skin and eyes and their importance in the acceptance and success of a digital human face, specifically in relation to the uncanny valley. The uncanny valley hypothesis states that as a human representation approaches photo-realism, subtle differences from reality become unsettling. Recent studies suggest that the uncanny valley could exist over a far greater range, affecting abstract human representations as well. These competing findings are explored by analyzing how changes to the surface of a digital character affect its level of acceptance. A female facial model is used as a base to compare a spectrum of different simulated real-world materials. The variations range from materials that are nearly identical to human skin, to those that are completely divergent from it, thus unnatural. After studying this catalogue of materials, it is concluded that given the right conditions, the uncanny valley can occur when facial representations are very near realism, as well as when human-likeness is quite distant from reality.

Recent Advances on Hydrogenic Retention in ITER's Plasma-Facing Materials: BE, C, W.  

SciTech Connect

Management of tritium inventory remains one of the grand challenges in the development of fusion energy and the choice of plasma-facing materials is a key factor for in-vessel tritium retention. The Atomic and Molecular Data Unit of the International Atomic Energy Agency organized a Coordinated Research Project (CRP) on the overall topic of tritium inventory in fusion reactors during the period 2001-2006. This dealt with hydrogenic retention in ITER's plasma-facing materials, Be, C, W, and in compounds (mixed materials) of these elements as well as tritium removal techniques. The results of the CRP are summarized in this article together with recommendations for ITER. Basic parameters of diffusivity, solubility and trapping in Be, C and W are reviewed. For Be, the development of open porosity can account for transient hydrogenic pumping but long term retention will be dominated by codeposition. Codeposition is also the dominant retention mechanism for carbon and remains a serious concern for both Be and C containing layers. Hydrogenic trapping in unirradiated tungsten is low but will increase with ion and neutron damage. Mixed materials will be formed in a tokamak and these can also retain significant amounts of hydrogen isotopes. Oxidative and photon-based techniques for detritiation of plasma-facing components are described.

Challenges in petroleum policy for the next president of Mexico  

Science Conference Proceedings (OSTI)

The next president of Mexico, who will take office on Dec. 1, 1994, faces the challenge of construction a new legal, commercial, and philosophical paradigm for the oil and gas industry in Mexico. As this review of petroleum policies and measures of the past 5 years will show, the existing paradigm has worked only imperfectly, and there are a number of items of unfinished business that the new administration must address. The paper discusses upstream developments and trends, trade issues, environmental gasoline, environmental and industrial safety, natural gas distribution, Pemex morale problems, Nafta and the presidency, project financing, regulatory risk, paradox of financial strategy and Nafta's promise.

Atoms for Peace After 50 Years: The New Challenges and Opportunities  

SciTech Connect

This report draws on a series of international workshops held to mark the fiftieth anniversary of President Dwight D. Eisenhower's Atoms for Peace address before the United Nations General Assembly. A half-century after President Eisenhower's landmark speech, the world is vastly different, but mankind still faces the challenge he identified--gaining the benefits of nuclear technology in a way that limits the risks to security. Fifty years after Eisenhower declared that the people of the world should be ''armed with the significant facts of today's existence,'' the consequences of his bold vision should be evaluated to provide a foundation upon which to shape the next fifty years. Policy and technology communities cannot escape the legacy of a half-century of nuclear technology expansion. At the same time, citizens need to consider the future role of military and civilian nuclear technology in a global strategy to meet the challenges of the twenty-first century. The new century brought with it a set of contradictions regarding nuclear technology. Nuclear knowledge, technology, materials, and facilities have spread around the world, but control and management of the nuclear genie have not kept pace. The Cold War is over, but not the threat from weapons of mass destruction, including the prospect that nuclear, chemical, or biological weapons may get into the hands of terrorists. Nevertheless, mankind continues to explore the frontiers of technology, including nuclear technology. Public concern about nuclear safety and security--exacerbated by accidents, nuclear weapon proliferation, and terrorism--confronts major growth in applications of nuclear technology in nuclear power, medicine, agriculture, and industry. While some developed countries have essentially stopped civilian nuclear-power expansion, mainly for economic reasons, several developing states--notably China and India--plan increases in the nuclear generation of electricity. Ironically, while governments still seek answers to long-term, nuclear waste disposal, other concerns about the environmental health of the planet such as climate change, regional air pollution, and possible rising natural gas prices have also renewed interest in nuclear power, even in countries that once sought to terminate their own nuclear programs. Many of these contradictions can and will be resolved--for better or worse. A wide range of forces--economic, political, and technical--will determine the impact of nuclear technology in the future, and no consensus exists on the outcome. The significance of nuclear technology for civilian or military purposes may expand, contract, or remain the same. This suggests a matrix of basic possibilities from which we focus on five alternative futures: (1) More civilian/Less military significance, (2) Less civilian/Less military significance, (3) Less civilian/More military significance, and (4) More civilian/More military significance. Of course, changed circumstances could also result in (5) the significance of both civilian and military nuclear technologies remaining about the same as today. Experts offer compelling logic why each of these alternatives is more likely or desirable. For each of these futures or their modifications, a more comprehensive vision can be presented and specific measures recommended. Some call for a new nuclear ''compact'' or ''bargain'' to share benefits and reduce risks. No matter which alternative future emerges, however, dealing with the legacy of existing civilian and military nuclear materials and infrastructure will keep important nuclear issues active for the next half-century.

Unusual HVAC challenges require innovative solutions  

SciTech Connect

There were many reasons behind Motorola`s decision to build the first 225,000 sq ft of a planned one million sq ft manufacturing facility in Chihuahua, Mexico. Among these were the availability of skilled labor in the area, lower construction costs, some export tax advantages, and the close proximity to the US border. The new facility is made up of a variety of functional areas that together create an impressively efficient plant. Phase 1 construction included a large manufacturing floor, shipping and receiving areas, a bulk storage facility, and a large office area with a view of the factory floor. The structure also houses a retail store where Motorola consumer products are sold, a conference and banquet center, a commercial kitchen, and dining facilities for 750. The design cooling load is 750 tons; the heating load is 4.5 million Btuh. The paper discusses the challenging location, the HVAC system, and the future expansion planned.

Challenges in the Development of Advanced Reactors  

SciTech Connect

Past generations of nuclear reactors have been successively developed and the next generation is currently being developed, demonstrating the constant progress and technical and industrial vitality of nuclear energy. In 2000 US Department of Energy launched Generation IV International Forum (GIF) which is one of the main international frameworks for the development of future nuclear systems. The six systems that were selected were: sodium cooled fast reactor, lead cooled fast reactor, supercritical water cooled reactor, very high temperature gas cooled reactor (VHTR), gas cooled fast reactor and molten salt reactor. This paper discusses some of the proposed advanced reactor concepts that are currently being researched to varying degrees in the United States, and highlights some of the major challenges these concepts must overcome to establish their feasibility and to satisfy licensing requirements.

The production of biofuels from lignocellulosic feedstocks requires the depolymerization of cell wall carbohydrates into simple sugars that can be utilized during fermentation. However, the desired cellulose microfibrils are surrounded by a matrix of lignin and hemicellulose, which greatly inhibits their accessibility to hydrolytic enzymes [1,2].

According to the model, the C 1 component first disrupted and swelled the crystalline cellulose, possibly releasing soluble oligo saccharides into solution. The C x compo- nent, which was shown to have endoglucanase activity, was then able to effectively hydrolyze the previously inaccessible substrate along with the soluble oligo- saccharides. Furthermore, the activity of the mixture was found to be higher than the activity of each com- ponent acting alone, indicating that the components were acting synergistically.

Future power supply  

Science Conference Proceedings (OSTI)

This article is a review of the U.S. needs for new generating capacity during the next decade. Considering regulatory and technical issues and assuming a modest annual load growth of 1.9%, it is anticipated that there will be a 90 GWe deficit by the year 2000. Likely sources to provide this additional capacity are reviewed, and it is concluded that most new plants will be gas-fired simple-cycle combustion turbines. This will occur mainly because the country has excess baseload capacity and needs to add a considerable amount of peaking capacity to bring the generation mix into balance. It is also concluded that fossil-fueled plants will provide the country`s baseload for the foreseeable future.

RHIC low-energy challenges and plans  

SciTech Connect

Future Relativistic Heavy Ion Collider (RHIC) runs, including a portion of FY10 heavy ion operations, will explore collisions at center of mass energies of 5-50 GeV/n (GeV/nucleon). Operations at these energies is motivated by the search for a possible QCD phase transition critical point. The lowest end of this energy range is nearly a factor of four below the nominal RHIC injection center of mass energy {radical}s = 19.6 GeV/n. There are several operational challenges in the RHIC low-energy regime, including harmonic number changes, small longitudinal acceptance, lowered magnet field quality, nonlinear orbit control, and luminosity monitoring. We report on the experience with these challenges during beam tests with gold beams in March 2008. This includes first operations at {radical}s = 9.18 GeV/n, first beam experience at {radical}s = 5 GeV/n, and luminosity projections for near-term operations.

Top Ten Interaction Challenges in Extreme-Scale Visual Analytics  

Science Conference Proceedings (OSTI)

The chapter presents ten selected user interfaces and interaction challenges in extreme-scale visual analytics. The study of visual analytics is often referred to as 'the science of analytical reasoning facilitated by interactive visual interfaces' in the literature. The discussion focuses on the issues of applying visual analytics technologies to extreme-scale scientific and non-scientific data ranging from petabyte to exabyte in sizes. The ten challenges are: in situ interactive analysis, user-driven data reduction, scalability and multi-level hierarchy, representation of evidence and uncertainty, heterogeneous data fusion, data summarization and triage for interactive query, analytics of temporally evolving features, the human bottleneck, design and engineering development, and the Renaissance of conventional wisdom. The discussion addresses concerns that arise from different areas of hardware, software, computation, algorithms, and human factors. The chapter also evaluates the likelihood of success in meeting these challenges in the near future.

A typical input to the program often has hundreds, sometimes thousands of parameters which are typically tweaked by a buildings expert to get it right . This process can sometimes take months. Autotune is an ongoing research effort employing machine learning techniques to automate the tuning of the input parameters for an EnergyPlus input description of a building. Even with automation, the computational challenge faced to run the tuning simulation ensemble is daunting and requires the use of supercomputers to make it tractable in time. In this proposal, we describe the scope of the problem, the technical challenges faced and overcome, the machine learning techniques developed and employed, and the software infrastructure developed/in development when taking the EnergyPlus engine, which was primarily designed to run on desktops, and scaling it to run on shared memory supercomputers (Nautilus) and distributed memory supercomputers (Frost and Titan). The parametric simulations produce data in the order of tens to a couple of hundred terabytes.We describe the approaches employed to streamline and reduce bottlenecks in the workflow for this data, which is subsequently being made available for the tuning effort as well as made available publicly for open-science.

Alternative Energy Development and China's Energy Future  

SciTech Connect

In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis used to evaluate the energy and emission impact of two pathways of alternative energy development. The results show that China can only meets its 2015 and 2020 targets for non-fossil penetration if it successfully achieves all of its capacity targets for 2020 with continued expansion through 2030. To achieve this level of alternative generation, significant amounts of raw materials including 235 Mt of concrete, 54 Mt of steel, 5 Mt of copper along with 3 billion tons of water and 64 thousand square kilometers of land are needed. China’s alternative energy supply will likely have relatively high average energy output to fossil fuel input ratio of 42 declining to 26 over time, but this ratio is largely skewed by nuclear and hydropower capacity. With successful alternative energy development, 32% of China’s electricity and 21% of its total primary energy will be supplied by alternative energy by 2030. Compared to the counterfactual baseline in which alternative energy development stumbles and China does not meet its capacity targets until 2030, alternative energy development can displace 175 Mtce of coal inputs per year and 2080 Mtce cumulatively from power generation by 2030. In carbon terms, this translates into 5520 Mt of displaced CO{sub 2} emissions over the twenty year period, with more than half coming from expanded nuclear and wind power generation. These results illustrate the critical role that alternative energy development can play alongside energy efficiency in reducing China’s energy-related carbon emissions.

Lithium As Plasma Facing Component for Magnetic Fusion Research  

SciTech Connect

The use of lithium in magnetic fusion confinement experiments started in the 1990's in order to improve tokamak plasma performance as a low-recycling plasma-facing component (PFC). Lithium is the lightest alkali metal and it is highly chemically reactive with relevant ion species in fusion plasmas including hydrogen, deuterium, tritium, carbon, and oxygen. Because of the reactive properties, lithium can provide strong pumping for those ions. It was indeed a spectacular success in TFTR where a very small amount (~ 0.02 gram) of lithium coating of the PFCs resulted in the fusion power output to improve by nearly a factor of two. The plasma confinement also improved by a factor of two. This success was attributed to the reduced recycling of cold gas surrounding the fusion plasma due to highly reactive lithium on the wall. The plasma confinement and performance improvements have since been confirmed in a large number of fusion devices with various magnetic configurations including CDX-U/LTX (US), CPD (Japan), HT-7 (China), EAST (China), FTU (Italy), NSTX (US), T-10, T-11M (Russia), TJ-II (Spain), and RFX (Italy). Additionally, lithium was shown to broaden the plasma pressure profile in NSTX, which is advantageous in achieving high performance H-mode operation for tokamak reactors. It is also noted that even with significant applications (up to 1,000 grams in NSTX) of lithium on PFCs, very little contamination (< 0.1%) of lithium fraction in main fusion plasma core was observed even during high confinement modes. The lithium therefore appears to be a highly desirable material to be used as a plasma PFC material from the magnetic fusion plasma performance and operational point of view. An exciting development in recent years is the growing realization of lithium as a potential solution to solve the exceptionally challenging need to handle the fusion reactor divertor heat flux, which could reach 60 MW/m2 . By placing the liquid lithium (LL) surface in the path of the main divertor heat flux (divertor strike point), the lithium is evaporated from the surface. The evaporated lithium is quickly ionized by the plasma and the ionized lithium ions can provide a strongly radiative layer of plasma ("radiative mantle"), thus could significantly reduce the heat flux to the divertor strike point surfaces, thus protecting the divertor surface. The protective effects of LL have been observed in many experiments and test stands. As a possible reactor divertor candidate, a closed LL divertor system is described. Finally, it is noted that the lithium applications as a PFC can be quite flexible and broad. The lithium application should be quite compatible with various divertor configurations, and it can be also applied to protecting the presently envisioned tungsten based solid PFC surfaces such as the ones for ITER. Lithium based PFCs therefore have the exciting prospect of providing a cost effective flexible means to improve the fusion reactor performance, while providing a practical solution to the highly challenging divertor heat handling issue confronting the steadystate magnetic fusion reactors.

Toward An Integrated History to Guide the Future  

Science Conference Proceedings (OSTI)

Abstract Many contemporary societal challenges manifest themselves in the domain of humanenvironment interactions. There is a growing recognition that responses to these challenges formulated within current disciplinary boundaries, in isolation from their wider contexts, cannot adequately address them. Here, we outline the need for an integrated, trans-disciplinary synthesis that allows for a holistic approach, and, above all, a much longer time perspective. We outline both the need for, and the fundamental characteristics of, what we call “integrated history.” This approach promises to yield new understandings of the relationship between the past, present and possible futures of our integrated human-environment system. We recommend a unique new focus of our historical efforts on the future, rather than the past, concentrated on learning about future possibilities from history. A growing worldwide community of trans-disciplinary scholars is forming around building this Integrated History and future of People on Earth (IHOPE). Building integrated models of past human societies and their interactions with their environments yields new insights into those interactions and can help to create a more sustainable and desirable future. The activity has become a major focus within the global change community.

Hydrogen: Fueling the Future  

DOE Green Energy (OSTI)

As our dependence on foreign oil increases and concerns about global climate change rise, the need to develop sustainable energy technologies is becoming increasingly significant. Worldwide energy consumption is expected to double by the year 2050, as will carbon emissions along with it. This increase in emissions is a product of an ever-increasing demand for energy, and a corresponding rise in the combustion of carbon containing fossil fuels such as coal, petroleum, and natural gas. Undisputable scientific evidence indicates significant changes in the global climate have occurred in recent years. Impacts of climate change and the resulting atmospheric warming are extensive, and know no political or geographic boundaries. These far-reaching effects will be manifested as environmental, economic, socioeconomic, and geopolitical issues. Offsetting the projected increase in fossil energy use with renewable energy production will require large increases in renewable energy systems, as well as the ability to store and transport clean domestic fuels. Storage and transport of electricity generated from intermittent resources such as wind and solar is central to the widespread use of renewable energy technologies. Hydrogen created from water electrolysis is an option for energy storage and transport, and represents a pollution-free source of fuel when generated using renewable electricity. The conversion of chemical to electrical energy using fuel cells provides a high efficiency, carbon-free power source. Hydrogen serves to blur the line between stationary and mobile power applications, as it can be used as both a transportation fuel and for stationary electricity generation, with the possibility of a distributed generation energy infrastructure. Hydrogen and fuel cell technologies will be presented as possible pollution-free solutions to present and future energy concerns. Recent hydrogen-related research at SLAC in hydrogen production, fuel cell catalysis, and hydrogen storage will be highlighted in this seminar.

The interplay between telecommunications and face-to-face interactions - an initial study using mobile phone data  

E-Print Network (OSTI)

In this study we analyze one year of anonymized telecommunications data for over one million customers from a large European cellphone operator, in order to investigate the relationship between people's calls and their physical location. We discover that more than 90% of users who have called each other have also shared the same space (cell tower), even if they live far apart. Moreover, we find that 69% of users who call each other frequently (at least once per month on average) have shared the same space at the same time - an instance that we call co-location. Co-locations appear highly indicative of coordination calls, which occur just before face-to-face meetings. Their number is highly predictable based on the amount of calls between two users and the distance between their home locations - suggesting a new way to quantify the interplay between telecommunications and face-to-face interactions.

Seismological challenges for stellar structure  

E-Print Network (OSTI)

Helioseismology has provided very detailed information about the solar interior, and extensive data on a large number of stars, although at less detail, are promised by the ongoing and upcoming asteroseismic projects. In the solar case there remain serious challenges in understanding the inferred solar structure, particularly in the light of the revised determinations of the solar surface composition. Also, a secure understanding of the origins of solar rotation as inferred from helioseismology, both in the radiative interior and in the convection zone, is still missing. In the stellar case challenges are certain to appear as the data allow more detailed inferences of the properties of stellar cores. Large remaining uncertainties in modelling concerns the properties of convective cores and other processes that may cause mixing. As a result of developing asteroseismic signatures addressing these and other issues, we can look forward to a highly challenging, and hence exciting, era of stellar astrophysics.

Status and Challenges in Electrochemical Energy Storage Technologies for Stationary Applications  

DOE Green Energy (OSTI)

There are a number of EES technologies that exist and are potential candidates for the stationary applications. Among the most promising ones are batteries that store electrical energy via electrochemical conversion and release it according to demands. But all the exiting battery technologies are facing challenges in cost and performance for the particular applications. To advance the technology and accelerate market penetration requires substantial progress in advanced materials and chemistries, along with design and engineering. Given this is a relative new field to the materials community, this issue JOM includes a topic on the stationary electrical energy storage, with focus on the needs, requirements and status and challenges in technologies.

Agent 2003 Conference on Challenges in Social Simulation  

Science Conference Proceedings (OSTI)

Welcome to the Proceedings of the fourth in a series of agent simulation conferences cosponsored by Argonne National Laboratory and The University of Chicago. Agent 2003 is the second conference in which three Special Interest Groups from the North American Association for Computational Social and Organizational Science (NAACSOS) have been involved in planning the program--Computational Social Theory; Simulation Applications; and Methods, Toolkits and Techniques. The theme of Agent 2003, Challenges in Social Simulation, is especially relevant, as there seems to be no shortage of such challenges. Agent simulation has been applied with increasing frequency to social domains for several decades, and its promise is clear and increasingly visible. Like any nascent scientific methodology, however, it faces a number of problems or issues that must be addressed in order to progress. These challenges include: (1) Validating models relative to the social settings they are designed to represent; (2) Developing agents and interactions simple enough to understand but sufficiently complex to do justice to the social processes of interest; (3) Bridging the gap between empirically spare artificial societies and naturally occurring social phenomena; (4) Building multi-level models that span processes across domains; (5) Promoting a dialog among theoretical, qualitative, and empirical social scientists and area experts, on the one hand, and mathematical and computational modelers and engineers, on the other; (6) Using that dialog to facilitate substantive progress in the social sciences; and (7) Fulfilling the aspirations of users in business, government, and other application areas, while recognizing and addressing the preceding challenges. Although this list hardly exhausts the challenges the field faces, it does identify topics addressed throughout the presentations of Agent 2003. Agent 2003 is part of a much larger process in which new methods and techniques are applied to difficult social issues. Among the resources that give us the prospect of success is the innovative and transdisciplinary research community being built. We believe that Agent 2003 contributes to further progress in computational modeling of social processes, and we hope that you find these Proceedings to be stimulating and rewarding. As the horizons of this transdiscipline continue to emerge and converge, we hope to provide similar forums that will promote development of agent simulation modeling in the years to come.

Conformal formulation of cosmological futures  

E-Print Network (OSTI)

We summarise the new conformal framework of an Anisotropic Future Endless Universe and an Anisotropic Future Singularity. Both new definitions are motivated by, but not restricted to quiescent cosmology and the Weyl curvature hypothesis, which previously only possessed a framework for a classical initial state of the universe, namely the Isotropic Singularity. Some of the features of the framework are briefly discussed.

Program Pu Futures 2006  

SciTech Connect

The coordination chemistry of plutonium remains relatively unexplored. Thus, the fundamental coordination chemistry of plutonium is being studied using simple multi-dentate ligands with the intention that the information gleaned from these studies may be used in the future to develop plutonium-specific sequestering agents. Towards this goal, hard Lewis-base donors are used as model ligands. Maltol, an inexpensive natural product used in the commercial food industry, is an ideal ligand because it is an all-oxygen bidentate donor, has a rigid structure, and is of small enough size to impose little steric strain, allowing the coordination preferences of plutonium to be the deciding geometric factor. Additionally, maltol is the synthetic precursor of 3,4-HOPO, a siderophore-inspired bidentate moiety tested by us previously as a possible sequestering agent for plutonium under acidic conditions. As comparisons to the plutonium structure, Ce(IV) complexes of the same and related ligands were examined as well. Cerium(IV) complexes serve as good models for plutonium(IV) structures because Ce(IV) has the same ionic radius as Pu(IV) (0.94 {angstrom}). Plutonium(IV) maltol crystals were grown out of a methanol/water solution by slow evaporation to afford red crystals that were evaluated at the Advanced Light Source at Lawrence Berkeley National Laboratory using single crystal X-ray diffraction. Cerium(IV) complexes with maltol and bromomaltol were crystallized via slow evaporation of the mother liquor to afford tetragonal, black crystals. All three complexes crystallize in space group I4{sub 1}/a. The Ce(IV) complex is isostructural with the Pu(IV) complex, in which donating oxygens adopt a trigonal dodecahedral geometry around the metal with the maltol rings parallel to the crystallographic S{sub 4} axis and lying in a non-crystallographic mirror plane of D{sub 2d} molecular symmetry (Fig 1). The metal-oxygen bonds in both maltol complexes are equal to within 0.04 {angstrom} for each oxygen type. In contrast to the maltol structures, the cerium(IV) bromomaltol complex arranges the maltol rings in a drastically different manner while maintaining the S{sub 4} crystallographic symmetry (Fig 2). The coordination geometry around the cerium remains a trigonal dodecahedron, but the chelating ligands span a different set of edges as in the maltol structures; the two-fold related bromomaltol ligands twist away from planarity, breaking the D{sub 2d} molecular symmetry. It is unlikely that steric interaction with a bromine on the same molecule would have caused the observed rearrangement, as there would be sufficient separation between them to accommodate their bulk in the geometry of the plutonium and cerium maltol complexes. The extended packing in the unit cell of both the plutonium and cerium maltol crystals indicates that pi stacking occurs throughout the lattice via the maltol rings with close contacts between rings of approximately 3.6 {angstrom}. Introduction of the bromine to this structure would disrupt the packing that would allow these interactions, causing the molecule to adopt the geometry present in the bromomaltol structure. In this unexpected arrangement the complex is still able to maintain some pi stacking with the maltol rings of adjacent molecules with a close contact of approximately 3.3 {angstrom}. Additionally, the bromine on each ligand is arranged such that its next closest contact is with a bromine 3.64 {angstrom} away on another molecule. Despite the different ligand geometry, the bromomaltol structure exhibits metal-oxygen bond distances that are within 0.06 {angstrom} of those in the maltol complexes.

Coal and nuclear power: Illinois' energy future  

SciTech Connect

This conference was sponsored by the Energy Resources Center, University of Illinois at Chicago; the US Department of Energy; the Illinois Energy Resources Commission; and the Illinois Department of Energy and Natural Resources. The theme for the conference, Coal and Nuclear Power: Illinois' Energy Future, was based on two major observations: (1) Illinois has the largest reserves of bituminous coal of any state and is surpassed in total reserves only by North Dakota, and Montana; and (2) Illinois has made a heavy commitment to the use of nuclear power as a source of electrical power generation. Currently, nuclear power represents 30% of the electrical energy produced in the State. The primary objective of the 1982 conference was to review these two energy sources in view of the current energy policy of the Reagan Administration, and to examine the impact these policies have on the Midwest energy scene. The conference dealt with issues unique to Illinois as well as those facing the entire nation. A separate abstract was prepared for each of the 30 individual presentations.

Applied Mathematics at the U.S. Department of Energy: Past, Present and a View to the Future  

Science Conference Proceedings (OSTI)

Over the past half-century, the Applied Mathematics program in the U.S. Department of Energy's Office of Advanced Scientific Computing Research has made significant, enduring advances in applied mathematics that have been essential enablers of modern computational science. Motivated by the scientific needs of the Department of Energy and its predecessors, advances have been made in mathematical modeling, numerical analysis of differential equations, optimization theory, mesh generation for complex geometries, adaptive algorithms and other important mathematical areas. High-performance mathematical software libraries developed through this program have contributed as much or more to the performance of modern scientific computer codes as the high-performance computers on which these codes run. The combination of these mathematical advances and the resulting software has enabled high-performance computers to be used for scientific discovery in ways that could only be imagined at the program's inception. Our nation, and indeed our world, face great challenges that must be addressed in coming years, and many of these will be addressed through the development of scientific understanding and engineering advances yet to be discovered. The U.S. Department of Energy (DOE) will play an essential role in providing science-based solutions to many of these problems, particularly those that involve the energy, environmental and national security needs of the country. As the capability of high-performance computers continues to increase, the types of questions that can be answered by applying this huge computational power become more varied and more complex. It will be essential that we find new ways to develop and apply the mathematics necessary to enable the new scientific and engineering discoveries that are needed. In August 2007, a panel of experts in applied, computational and statistical mathematics met for a day and a half in Berkeley, California to understand the mathematical developments required to meet the future science and engineering needs of the DOE. It is important to emphasize that the panelists were not asked to speculate only on advances that might be made in their own research specialties. Instead, the guidance this panel was given was to consider the broad science and engineering challenges that the DOE faces and identify the corresponding advances that must occur across the field of mathematics for these challenges to be successfully addressed. As preparation for the meeting, each panelist was asked to review strategic planning and other informational documents available for one or more of the DOE Program Offices, including the Offices of Science, Nuclear Energy, Fossil Energy, Environmental Management, Legacy Management, Energy Efficiency & Renewable Energy, Electricity Delivery & Energy Reliability and Civilian Radioactive Waste Management as well as the National Nuclear Security Administration. The panelists reported on science and engineering needs for each of these offices, and then discussed and identified mathematical advances that will be required if these challenges are to be met. A review of DOE challenges in energy, the environment and national security brings to light a broad and varied array of questions that the DOE must answer in the coming years. A representative subset of such questions includes: (1) Can we predict the operating characteristics of a clean coal power plant? (2) How stable is the plasma containment in a tokamak? (3) How quickly is climate change occurring and what are the uncertainties in the predicted time scales? (4) How quickly can an introduced bio-weapon contaminate the agricultural environment in the US? (5) How do we modify models of the atmosphere and clouds to incorporate newly collected data of possibly of new types? (6) How quickly can the United States recover if part of the power grid became inoperable? (7) What are optimal locations and communication protocols for sensing devices in a remote-sensing network? (8) How can new materials be designed with a specified desira

Prediction of power requirements for a longwall armored face conveyor  

SciTech Connect

Longwall armored face conveyors (AFC`s) have traditionally been designed using a combination of heuristics and simple models. However, as longwalls increase in length, these design procedures are proving to be inadequate. The result has either been a costly loss of production due to AFC stalling or component failure, or larger than necessary capital investment due to overdesign. In order to allow accurate estimation of the power requirements for an AFC, this paper develops a comprehensive model of all the friction forces associated with the AFC. Power requirement predictions obtained from these models are then compared with measurements from two mine faces.

Eastern Europe Research Reactor Initiative nuclear education and training courses - Current activities and future challenges  

Science Conference Proceedings (OSTI)

The Eastern Europe Research Reactor Initiative was established in January 2008 to enhance cooperation between the Research Reactors in Eastern Europe. It covers three areas of research reactor utilisation: irradiation of materials and fuel, radioisotope production, neutron beam experiments, education and training. In the field of education and training an EERRI training course was developed. The training programme has been elaborated with the purpose to assist IAEA Member States, which consider building a research reactor (RR) as a first step to develop nuclear competence and infrastructure in the Country. The major strength of the reactor is utilisation of three different research reactors and a lot of practical exercises. Due to high level of adaptability, the course can be tailored to specific needs of institutions with limited or no access to research reactors. (authors)

European oil companies struggle to meet the challenge of an uncertain future  

Science Conference Proceedings (OSTI)

Oil companies have traditionally favored vertical integration, controlling the flow of oil from the drilling rig through refineries to the gasoline pump. The development of the downstream infrastructure has largely been driven by the retail market, with other fuels often treated as {open_quotes}marginal{close_quotes} businesses that leverage the retail distribution infrastructure. High-margin niche business such as lubricants and bitumen exist, but their volumes are typically small compared to the retail market. Other high-volume businesses such as aviation and heating fuels are closely tied to traded markets and generally have small market margins. Price levels at the retail site are crucial to the profitability of the downstream business. Price levels at European retail stations have historically been high when compared with North American prices, owing to government taxation. Despite the efforts of the oil companies to educate the consumer on what is the real cause of high prices, the oil majors are blamed when fuel prices fall, the consumer often feels as though lower prices had to be forced on the oil companies. Therefore, European consumers are more price sensitive than consumers elsewhere, and in markets which are deregulated on price, oil companies are losing market share to hypermarkets and supermarkets. In the U.S., increases in fuel tax levels are likely to result in a heightened price awareness for the average American, increasing the probability that hypermarkets will also enter the U.S fuels market.

The challenge of unconventional superconductivity.  

SciTech Connect

During the past few decades, several new classes of superconductors have been discovered that do not appear to be related to traditional superconductors. The source of the superconductivity of these materials is likely different from the electron-ion interactions that are at the heart of conventional superconductivity. Developing a rigorous theory for any of these classes of materials has proven to be a difficult challenge and will remain one of the major problems in physics in the decades to come.
