    Stahl, M.S. )

    1993-01-01

    The Army Corps of Engineers, Pacific Ocean Division, participated in the interagency case study of sea level rise for Yap State in the Federated States of Micronesia. The study, on behalf of the National Oceanic and Atmospheric Administration, was in support of the Intergovernmental Panel on Climate Change. Engineering and environmental analyses indicate that resources within Yap State at risk from a 1.0 meter rise in sea level by the year 2100 are substantial, including coral reefs, sea grass beds, wetlands, native mangrove forests, groundwater, archaeological and cultural resources, and shoreline infrastructure. Severe constraints associated with land ownership patterns have helped prevent the potential for greater impact. Yet these same constraints will likely hinder future decisions regarding retreat, accommodation, or protection strategies. As a result, there are special institutional and cultural challenges that face Yap in developing and implementing appropriate responses to accelerated sea level rise. These are made more difficult with the many uncertainties associated with current predictions regarding the greenhouse effect.

    1990-12-01

    The State of Yap in the Federated States of Micronesia is now entirely dependent on oil for electric power generation. The present high costs and limited capacity for electric power generation are major disincentives to the economic development of Yap. Preliminary proposals from two U.S. companies regarding waste-to-energy plants might furnish electricity to Yap below present costs. Yap and its sister state of Kosrae have agreed to jointly seek a grant from the U.S. Trade and Development Program (TDP) to cover three areas: An assessment of projected power generating requirements; A review of generating alternatives with emphasis on waste to energy generation; and An environmental analysis of the waste to energy alternatives. The government in Yap has two objectives: reduce the amount of money spent for diesel fuel now and in the future and make sufficient electricity available at a reasonable price to attract development for the economy of Yap. Officials on both Pohnpei and Kosrae echoed these objectives.

    Latin America is about 2.2 times the size of the United States and, in population, it exceeds the U.S. by 165 million people. A relatively high population growth rate, together with its vast underdeveloped natural resources, gives Latin America a tremendous potential for progress. The desire of governments to advance economically, together with the proper stimuli to education and to the managerial resources, should translate this potential in reality. This is evident in a number of regions.

    Hosmer, A.W.; Vitale, E.M.; Guerrero, C.R.; Solorzano-Vincent, L.

    1998-12-31

    Latin America is the most urbanized region in the developing world. In recent years, significant economic growth has resulted in population migration from rural areas to urban centers, as well as in a substantial rise in the standard of living within the Region. These changes have impacted the air quality of Latin American countries as increased numbers of industrial facilities and motor vehicles release pollutants into the air. With the advent of new free trade agreements such as MERCOSUR and NAFTA, economic activity and associated pollutant levels can only be expected to continue to expand in the future. In order to address growing air pollution problems, many Latin America countries including Argentina, Brazil, Chile, Columbia, Costa Rica, and Mexico have passed, or will soon pass, new legislation to develop and strengthen their environmental frameworks with respect to air quality. As a first step toward understanding the impacts that this increased environmental regulation will have, this paper will examine the regulatory systems in six Latin American countries with respect to ambient air quality and for each of these countries: review a short history of the air quality problems within the country; outline the legal and institutional framework including key laws and implementing institutions; summarize in brief the current status of the country in terms of program development and implementation; and identify projected future trends. In addition, the paper will briefly review the international treaties that have bearing on Latin American air quality. Finally, the paper will conclude by identifying and exploring emerging trends in individual countries and the region as a whole.

    Sanchez-Sierra, G. )

    1993-02-01

    In the last two decades, the Latin America/Carribean region has become increasingly dependent on electricity to meet growing demands for energy. Hydropower is the prevailing source for meeting this need. Hydroelectric generation increased at an annual average rate of nearly 9% between 1971 and 1989. HYdro now provides more than two-thirds of total electric power generated in Latin America and the Caribbean. The only other predominant source used for electric generation is fossil fuels. In this region there are several trends developing. They include: developing more small hydro facilities, opportunities for sharing water resources, an interest in changing the approach to water use regulation, and possibilities for more participation by the private sector. Overall, hydro appears to have a favorable competitive position in the power industry in the Latin America/Caribbean region.

    The authors discusses the changes that are taking place in Argentina as well as in all of Latin America today -- privatization, deregulation, and the modernization of the economy, changes which will serve to strengthen the governments and provide a better quality of life for all of them. He gives an insight into the factors which helped bring about these changes, the support they are receiving, the problems which persist, and the measures that still must be taken so that these positive changes remain in place. He offers some useful information that will perhaps contribute to their understanding of the vast area which he refers to as Latin America, and more specifically, gives a thumbnail sketch of what is happening today in the Republic of Argentina. For many years now, Latin American leaders have travelled to other parts of the world and spoken about the plans and expectations for the region`s future. When these well-intentioned projects and plans never materialized, partners and supporters in the United States and other countries were frustrated and disappointed by the failure to make things work. The author`s intention here today is to describe things as they are, not as they might be, to tell about what is already happening in the sphere of business and growth of the economies in Latin America.

    This report compiles preliminary information that supports the premise that a repository is needed in Latin America and analyzes the nuclear situation (mainly in Argentina and Brazil) in terms of nuclear capabilities, inventories, and regional spent-fuel repositories. The report is based on several sources and summarizes (1) the nuclear capabilities in Latin America and establishes the framework for the need of a permanent repository, (2) the International Atomic Energy Agency (IAEA) approach for a regional spent-fuel repository and describes the support that international institutions are lending to this issue, (3) the current situation in Argentina in order to analyze the Argentinean willingness to find a location for a deep geological repository, and (4) the issues involved in selecting a location for the repository and identifies a potential location. This report then draws conclusions based on an analysis of this information. The focus of this report is mainly on spent fuel and does not elaborate on other radiological waste sources.

They claim that this algorithm works for every set of orthogonal Latin squares. We show that the algorithm only works for particular sets of orthogonal Latin squares. Furthermore, the algorithm is a more readable version of work previously published [Phys. Rev. A 70, 062101 (2004)].

    A procedure for extending the size of a Latin hypercube sample (LHS) with rank correlated variables is described and illustrated. The extension procedure starts with an LHS of size m and associated rank correlation matrix C and constructs a new LHS of size 2m that contains the elements of the original LHS and has a rank correlation matrix that is close to the original rank correlation matrix C. The procedure is intended for use in conjunction with uncertainty and sensitivity analysis of computationally demanding models in which it is important to make efficient use of a necessarily limited number of model evaluations.

    Case, C.W.

    1987-05-01

    The purpose of this guidebook is to help transfer information concerning alternative energy projects that have been tried on the Pacific islands affiliated with the US. These islands include those in American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia (Kosrae, Pohnpei, Truk, and Yap), Guam, and the Republics of the Marshall Islands and Palau. Distances are long between islands and populations are sparse, making communication and the transfer of information particularly difficult. A project that works on American Samoa might be appropriate for Yap, but to get this information to the proper people on Yap in a reasonable period of time is extremely difficult. This book describes 100 alternative energy projects that have been tried on the islands since the mid-1970's. This description and record of what has been done to date should be a source of ideas for energy workers, reduce duplication of work, and help encourage successes by describing other successes and failures. Alternative energy projects are projects that use indigenous, renewable resources in order to reduce local dependency on imported petroleum for electricity or liquid fuels. The islands have an apparent abundance of natural resources for this purpose such as the sun, rivers, vegetation, the ocean, and wind; and, ideally, it should be relatively simple to convert these resources to electricity or fuel. However, there are problems unique to the remote, tropical Pacific that often appear insurmountable, and successes to date are the results of unusual persistence, hard work, and ingenuity of those on the islands. Projects are confined to those that actually develop or demonstrate hardware. These projects use the complete spectrum of alternative technologies such as biomass conversion, wind electric, solar water heating, photovoltaics, wind water pumping, hydroelectric, water desalination, and integrated systems. 381 refs., 85 figs.

    The LHS UNIX Library/Standalone software provides the capability to draw random samples from over 30 distribution types. It performs the sampling by a stratified sampling method called Latin Hypercube Sampling (LHS). Multiple distributions can be sampled simultaneously, with user-specified correlations amongst the input distributions, LHS UNIX Library/ Standalone provides a way to generate multi-variate samples. The LHS samples can be generated either as a callable library (e.g., from within the DAKOTA software framework) or asmore » a standalone capability. LHS UNIX Library/Standalone uses the Latin Hypercube Sampling method (LHS) to generate samples. LHS is a constrained Monte Carlo sampling scheme. In LHS, the range of each variable is divided into non-overlapping intervals on the basis of equal probability. A sample is selected at random with respect to the probability density in each interval, If multiple variables are sampled simultaneously, then values obtained for each are paired in a random manner with the n values of the other variables. In some cases, the pairing is restricted to obtain specified correlations amongst the input variables. Many simulation codes have input parameters that are uncertain and can be specified by a distribution, To perform uncertainty analysis and sensitivity analysis, random values are drawn from the input parameter distributions, and the simulation is run with these values to obtain output values. If this is done repeatedly, with many input samples drawn, one can build up a distribution of the output as well as examine correlations between input and output variables.« less

    1999-06-01

    The management of spent sealed sources is considered by the International Atomic Energy Agency (IAEA) one of the greatest challenges faced by nuclear authorities today, especially in developing countries. One of the Agency`s initiatives to tackle this problem is the Spent Radium Sources Conditioning Project, a worldwide project relying on the regional co-operation between countries. A team from the Brazilian nuclear research institute Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) was chosen as the expert team to carry out the operations in Latin America; since December 1996 radium sources have been safely conditioned in Uruguay, Nicaragua, Guatemala, Ecuador and Paraguay. A Quality Assurance Program was established, encompassing the qualification of the capsule welding process, written operational procedures referring to all major steps of the operation, calibration of monitors and information retrievability. A 200L carbon steel drum-based packaging concept was used to condition the sources, its cavity being designed to receive the lead shield device containing stainless steel capsules with the radium sources. As a result of these operations, a total amount of 2,897 mg of needles, tubes, medical applicators, standard sources for calibration, lightning rods, secondary wastes and contaminated objects were stored in proper conditions and are now under control of the nuclear authorities of the visited countries.

    1995-08-01

    In recent years, Latin America`s hydrocarbons sector has been characterized by reorganization, revitalization, regional cooperation, environmental awakening, and steady expansion. The pattern of these changes, which appear to be the megatrends of the region`s hydrocarbons sector development, will continue during the rest of the 1990s. To further study the current situation and future prospects of Latin America`s hydrocarbons sector, we critically summarize in this short article the key issues in the region`s oil and gas development. These megatrends in Latin America`s hydrocarbons sector development will impact not only the future energy demand and supply in the region, but also global oil flows in the North American market and across the Pacific Ocean. Each country is individually discussed; pipelines to be constructed are discussed also.

    1993-02-01

    Over 350 oil discoveries were made in Latin America during the 1980s. About 12% are estimated to contain reserves greater than 100 MMBO. Several of the larger finds (>500 MMBO), such as Cusiana (Colombia), Furrial/Musipan (Venezuela), Cano Lima (Colombia) and Marlim (Brazil) represent an important part of the giant field found worldwide since 1980. Most of the larger discoveries were made by national oil companies in Venezuela, Mexico and Brazil. Undiscovered oil resources of 40-80 BBO are estimated to remain in the highest potential Latin American basins, including those in Mexico, based on historical field size data and current geological knowledge. Over 150 BBO of produced oil and proven reserves has been found in the same group of basins. The probability of finding large undiscovered oil and gas fields (>100 MMBOE) in selected established and mature Latin American basins is high. The Campos (Brazil), Llanos (Colombia), Magadalena (Colombia), Maracaibo (Venezuela), Marahon-Oriente-Putomayo (Peru-Ecuador-Colombia), Maturin (Venezuela), Reforma-Campeche (Mexico) and Ucayali (Peru) basins have the best possibility for such accumulations. Another tier of frontier and emerging basins may also contain significant resources, but limited data makes it difficult to estimate their undiscovered resources. Some of the higher potential basins in this group include the Sierra de Chiapas (Mexico/Guatemala), Huallaga (Peru), Yucatan (Mexico), Sabinas, and Burgos (Mexico) basins.

    2010-04-15

    Nine non-local databases were evaluated with respect to their suitability for the environmental assessment of industrial activities in Latin America. Three assessment methods were considered, namely Life Cycle Assessment (LCA), Environmental Impact Assessment (EIA) and air emission inventories. The analysis focused on data availability in the databases and the applicability of their international data to Latin American industry. The study showed that the European EMEP/EEA Guidebook and the U.S. EPA AP-42 database are the most suitable ones for air emission inventories, whereas the LCI database Ecoinvent is the most suitable one for LCA and EIA. Due to the data coverage in the databases, air emission inventories are easier to develop than LCA or EIA, which require more comprehensive information. One strategy to overcome the limitations of non-local databases for Latin American industry is the combination of validated data from international databases with newly developed local datasets.

    Liberal economic and political reforms in Latin America, a declining oil market in the US, and world events such as last year's Persian Gulf Crisis are making foreign investment in Latin America's energy sector increasingly attractive. The Persian Gulf crisis indicated the US must diversify oil sources; increased competition and deregulation in electric power generation and gas production are providing more opportunities for independent power producers at home and abroad; and Latin America's need for foreign financial and technical assistance are providing an important pull'' factor. Electricity needs in the developing world wig be huge in the years to come. In Latin America and the Caribbean, 66,500 mg of new capacity will be required by 1999. The developing world will require US $100 billion in energy investment a year. But Latin American countries will have trouble obtaining funds. The region will need to rely heavily on private international sources to finance future energy requirements. Multilateral development bank participation win remain critical, however, serving as a catalyst for government reform and private investment in the sector. In particular, World Bank lending will be focused on countries with a clear commitment to pricing reform, regulatory reform, competitive markets, non-market barriers, and technology transfer. Opportunities for foreign participation in the Latin American oil sector are particularly large in Ecuador, Peru, Argentina, and Venezuela. Mexico's plans for reform in the oil sector, a delicate issue in that country, appear to be less defined and likely to occur farther into the future. The conference made clear that a regulatory entity is needed even when the sector is owned by the government. Regulatory processes must be fair and transparent in order to ensure adequate financial and technical performance.

This expertise has been applied on an ongoing basis to the major refiners in the Middle East and the Asia-Pacific region, along with the US West Coast as region in its own right. Refinery modeling in these three areas has been ongoing for nearly 15 years at the Center, and the tools and information sources are now well developed. To date, the EWC has not applied these tools to Latin America. Although research on Latin America has been an ongoing area of concern at the Center in recent years, the information gathered to date is still not of the level of detail nor quality available for other areas. The modeling efforts undertaken in this report are of a ``baseline`` nature, designed to outline the major issues, attempt a first cut at emerging product balances, and, above all, to elicit commentary from those directly involved in the oil industry in the key countries modeled. Our experience in other regions has shown that it takes a few years dialogue with refiners and government planner in individual countries to develop a reliable database, as well as the insights into operational constraints and practices that make accurate modeling possible. This report is no more than a first step down the road.

    Nuclear programs in Argentina and Brazil can be traced to August 1945 when their scientific communities articulated responses to the atomic bombings of Japan. They culminated in attempts to develop independent nuclear programs, sharply opposed by the United States, during the nationalist governments of Juan Peron and Getulio Vargas. This dissertation, based on primary sources from the three nations, analyzes these programs and the American responses. Latin America entered the nuclear age attempting to control natural resources, to improve scientific establishments, and to appraise Latin American-United States relations. Despite some clear warnings about nuclear dangers, the new form of energy was seen as the solution to industrial problems, poverty, and outside political interference. International opposition, which may have included nuclear threats from the United States, blocked Argentina's first attempt in 1947. After 1948, Peron wanted a nuclear program for cheap energy and prestige. The qualifications of the Brazilian scientists gave more substance to their program. The program originated in August, 1945, but assumed national proportion with the government of Vargas in 1951. Lack of American cooperation forced Vargas to establish a secret program with Germany. American troops intervened taking over the German equipment already completed. The final collapse came about with Vargas' suicide in August, 1954.

    The Latin American and Caribbean region - comprising Mexico, Central and South America, and the Caribbean - is relatively well endowed with energy resources, although the distribution of these resources is uneven across countries. The region produces more energy than it consumes, and the surplus energy, which amounts to 3.6 million barrels of oil equivalent per day (boe/d), is mostly oil. While the region`s total oil (crude and products) exports decreased from 4.4 million barrels per day (b/d) in 1981 to 3.8 million b/d in 1992, its net oil exports increased from about 1.6 million b/d in 1981 to 2.8 million b/d in 1992. In 1993, the surplus oil in Latin America and the Caribbean remained at 2.8 million b/d. This report analyzes the key issues of the Latin American and Caribbean energy industry and presents the future outlook for oil, gas, coal, hydroelectricity, and nuclear power developments in the region. In addition, the status of biomass energy, geothermal, and other noncommercial energy in the region will be briefly discussed in the context of overall energy development. The rest of the report is organized as follows: Section II assesses the current situation of Latin American and Caribbean energy production and consumption, covering primary energy supply, primary energy consumption, downstream petroleum sector development, and natural gas utilization. Section III presents the results of our study of future energy growth in Latin America. Important hydrocarbons policy issues in the region are discussed in Section IV, and a summary and concluding remarks are provided in Section V.

    Countries in this report include Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, Trinidad and Tobago, and Venezuela. These ten countries are the most important oil and gas producers in the Latin American and the Caribbean region. In the following sections, the primary energy supply (oil, gas, coal, hydroelectricity, and nuclear power whenever they are applicable), primary energy consumption, downstream oil sector development, gas utilization are discussed for each of the ten countries. The report also presents our latest forecasts of petroleum product consumption in each country toward 2000, which form the basis of the outlook for regional energy production and consumption outlined in Report No 1. Since the bulk of primary energy supply and demand is hydrocarbons for many countries, brief descriptions of the important hydrocarbons policy issues are provided at the end of the each country sections.

  8. RECENT DEVELOPMENTS OF THE IRIS PROJECT OF INTEREST FOR LATIN AMERICA

    The IRIS (International Reactor Innovative and Secure) reactor design is being developed by an international consortium of 21 organizations from ten countries, including three members from Brazil and one from Mexico. This reflects the interest that Latin America has for a project which addresses the energy needs of the region. Presented here are some of the most recent developments in the IRIS project. The project's highest priority is the current pre-application licensing with the US NRC, which has required an investigation of the major accident sequences and a preliminary probabilistic risk assessment (PRA). The results of the accident analyses confirmed the outstanding inherent safety of the IRIS configuration and the PRA analyses indicated a core damage frequency due to internal events of the order of 2E-8. This not only highlights the enhanced safety characteristic of IRIS which should enhance its public acceptance, but it has also prompted IRIS to consider the possibility of being licensed without the need for off-site emergency response planning which would have a very positive economic implication. The modular IRIS, with each module rated at {approx} 335 MWe, is of course an ideal size for developing countries as it allows to easily introduce a moderate amount of power on limited electric grids. IRIS can be deployed in single modules in regions only requiring a few hundred MWs or in multiple modules deployed successively at time intervals in large urban areas requiring a larger amount of power increasing with time. IRIS is designed to operate ''hands-off'' as much as possible, with a small crew, having in mind deployment in areas with limited infrastructure. Thus IRIS has a 48-months maintenance interval, long refueling cycles in excess of three years, and is designed to increase as much as possible operational reliability. For example, the project has recently adopted internal control rod drive mechanisms to eliminate vessel head penetrations and the

    This paper describes the radium sources conditioning operation carried out in Latin American and the Caribbean by a team of the Brazilian federal research institute CDTN, as part of an International Atomic Energy Agency's hands-on assistance project to safely condition disused sources in developing countries. This initiative was spawned by the perceived hazard associated with the use of radium sources, caused mainly by the high likelihood that these sources leak during their use due to the accumulation of the radon gas in their interior. The conditions under which these sources are often stored in the target countries, without proper documentation, mixed with different radiation sources and under precarious conditions, urged the Agency to start this program at the end of 1996. The conditioning process starts with a pre-mission to the candidate country, when a place is selected for the forthcoming operation, suggest improvements in the local available infrastructure is suggest ed and gather the most complete information available about the country's source inventory is collected. The operation consists of transferring the sources from their original shields to sturdy multi-barrier packages, which are put under the control of the local nuclear authority. As part of the quality assurance program applied to this project, the relevant information about the conditioned inventory is recorded and made available to the host country, to the IAEA and to the conditioning team.

    In this study, polymer foam encapsulants provide mechanical, electrical, and thermal isolation in engineered systems. It can be advantageous to surround objects of interest, such as electronics, with foams in a hermetically sealed container in order to protect them from hostile environments or from accidents such as fire. In fire environments, gas pressure from thermal decomposition of foams can cause mechanical failure of sealed systems. In this work, a detailed uncertainty quantification study of polymeric methylene diisocyanate (PMDI)-polyether-polyol based polyurethane foam is presented and compared to experimental results to assess the validity of a 3-D finite element model of themore » heat transfer and degradation processes. In this series of experiments, 320 kg/m3 PMDI foam in a 0.2 L sealed steel container is heated to 1,073 K at a rate of 150 K/min. The experiment ends when the can breaches due to the buildup of pressure. The temperature at key location is monitored as well as the internal pressure of the can. Both experimental uncertainty and computational uncertainty are examined and compared. The mean value method (MV) and Latin hypercube sampling (LHS) approach are used to propagate the uncertainty through the model. The results of the both the MV method and the LHS approach show that while the model generally can predict the temperature at given locations in the system, it is less successful at predicting the pressure response. Also, these two approaches for propagating uncertainty agree with each other, the importance of each input parameter on the simulation results is also investigated, showing that for the temperature response the conductivity of the steel container and the effective conductivity of the foam, are the most important parameters. For the pressure response, the activation energy, effective conductivity, and specific heat are most important. The comparison to experiments and the identification of the drivers of uncertainty allow for

    are thus unknown. These effects are interesting on two accounts. First, even if underdeveloped countries cannot replicate the technical aspects of research, their influence on social practices is not kept within geographical or language barriers. The way they are handled in developed countries may become part of resistances to ethical imperialism. Second, these advances have economic consequences. Their full understanding and the creation of a scientific literacy essential for sound ethical analysis demand the creation of receptive capacity in developing countries. The morality of genomics research and its applications can be analyzed from two main vantage points. Some traditions stress the ethics of convictions (in Max Webers terms, Gesinnungsethik) while others rely on the ethics of responsibility (Verantwortungsethik). In different forms, the latter deals with the consequences of social action, scientific research in this case, and may or may not be related to utilitarian considerations. It may be hypothesized that convictions, mostly of a religious nature, dominate the argumentative preferences in Latin countries and continental European traditions which rely on virtues while responsibility is associated with a discourse based on rights prevalent in countries following the Anglo-Saxon pattern of thought. This finds expression in different legal systems (common law versus codes) and in the language used for deliberation and moral reasoning. Although results of US-based ELSI research may not be transferable to other cultural and economic contexts, they impact other societies and serve as models. Rarely do they apply completely in other settings. In a globalized world, both appropriate understanding of the scientific enterprise and its ethical or economic sustainability demand empirical analysis of the patterns of thought, main beliefs, and reactions toward the new knowledge and its applications. Anecdotal accounts show that expectations may be misleading and

  14. Seismic acquisition and processing methodologies in overthrust areas: Some examples from Latin America

    SciTech Connect (OSTI)

    Tilander, N.G.; Mitchel, R..

    1996-08-01

    Overthrust areas represent some of the last frontiers in petroleum exploration today. Billion barrel discoveries in the Eastern Cordillera of Colombia and the Monagas fold-thrust belt of Venezuela during the past decade have highlighted the potential rewards for overthrust exploration. However the seismic data recorded in many overthrust areas is disappointingly poor. Challenges such as rough topography, complex subsurface structure, presence of high-velocity rocks at the surface, back-scattered energy and severe migration wavefronting continue to lower data quality and reduce interpretability. Lack of well/velocity control also reduces the reliability of depth estimations and migrated images. Failure to obtain satisfactory pre-drill structural images can easily result in costly wildcat failures. Advances in the methodologies used by Chevron for data acquisition, processing and interpretation have produced significant improvements in seismic data quality in Bolivia, Colombia and Trinidad. In this paper, seismic test results showing various swath geometries will be presented. We will also show recent examples of processing methods which have led to improved structural imaging. Rather than focusing on {open_quotes}black box{close_quotes} methodology, we will emphasize the cumulative effect of step-by-step improvements. Finally, the critical significance and interrelation of velocity measurements, modeling and depth migration will be explored. Pre-drill interpretations must ultimately encompass a variety of model solutions, and error bars should be established which realistically reflect the uncertainties in the data.

    Following the successful scientific space missions by the European Space Agency (ESA) and the European Southern Observatory (ESO) in Chile, as well as the high-energy particle activities at CERN in Genve, we have created a Ph.D. program dedicated to the formation of scientists in the field of relativistic astrophysics. The students of such a program will lead the theoretical developments of one of the most active fields of research, based on the above observational and experimental facilities. This program needs expertise in the most advanced topics of mathematical and theoretical physics, and in relativistic field theories. It requires the ability to model the observational data received from the above facilities, as well as all the basic knowledge in astronomy, astrophysics and cosmology. This activity is necessarily international, no single university can cover the broad expertises. From this, the proposed program of the IRAP Ph.D., in one of the youngest and most dynamical French universities, pole of research and teaching in the Euro-Mediterranean region (PRES): the University of Nice. It benefits from the presence of the astrophysics research institute of Observatoire de la Cte d’Azur involved in relativistic and non-photonic astrophysics. The participation of the Freie Universitaet Berlin, Oldenburg and Bremen Universities and of the Einstein Institute in Potsdam offers the possibility of teaching in relativistic field theories at the highest level. The University of Savoy offers the link to the particle physics at CERN. The activities at the University of Rome, at Stockholm University and at ICRANet offer teaching programs in all the fields of relativistic astrophysics, including cosmology, the physics of gravitational collapse, gamma-ray bursts, and black hole physics. Finally, the University of Ferrara will be present with lectures and researches in the topics they have pioneered such as x-ray astrophysics and observational cosmology. Through ICRANet the extra-European connections with Brazil, China and India will be guaranteed: in China, with the Shanghai Observatory of the Chinese Academy of Science, studying the formation and evolution of large-scale structure and galaxies; in India, with the Indian Centre for Space Physics (ICSP), renowned for its research on compact objects as well as on solar physics and astrochemistry; in Brazil with ICRANet Brazil where a successful program of research and teaching in relativistic astrophysics has been established in recent years.

  7. Gaining momentum

    SciTech Connect (OSTI)

    Burr, M.T.

    1995-10-01

    Few regions of the world exemplify the variety of approaches to power sector reform as thoroughly as Latin America. At one end of the spectrum stands Chile, which has successfully restructured its electric power industry, privatizing a large share of its formerly state-owned utility assets. Of all power markets in Latin America, Chile`s is the most open to private developers, with transparent pricing policies and competitive procurement procedures. At the other end of the spectrum, Venezuela`s privatization program has stalled, and the power market has become less accessible to private investment than before the current administration was elected. Many Latin American countries share some important challenges. First, a lack of credit worthiness among electric utilities makes it difficult to finance power projects that rely on long-term power sales agreements. Second, lingering fallout from Mexico`s financial crisis continues to affect commercial lenders` confidence in Latin America in general. Third, efforts at privatization and power market liberalization have proceeded in fits and starts, with some countries seeming to take as many steps backwards as forward. Nevertheless, Latin America remains one of the most attractive regions of the world for independent power development. This paper examines recent developments in key markets.

  8. Oil industry development and trade liberalization in the Western Hemisphere

    SciTech Connect (OSTI)

    Randall, S.J.

    1993-12-31

    This paper provides an overview of oil industry developments in the Western Hemisphere with particular emphasis on Latin America since the inauguration of the Enterprise for the Americas Initiative by George Bush. The author discusses these developments in the context of the Canada-U.S. Free Trade Agreement (concluded in 1989), and the negotiation in 1992 of the North American Free Trade Agreement (NAFTA). This paper is concerned essentially with the oil industry and does not discuss the importance of natural gas for Canadian producers nor the fact that much of Latin American oil production (notably in Mexico) is associated with natural gas. The author examines the shift to trade and investment liberalization and privatization in the 1980s and early 1990s, especially in Latin America--where the most dramatic transformation has occurred. The author suggests that investment patterns in the industry have been only marginally related to trade liberalization, and have derived more from considerations of resource availability, exploration and development costs, market factors, and the general state of the international economy--all of which have contributed in the 1980s to significant restructuring and downsizing among a number of major corporations. The author also notes the important increase in an internal Latin American market, and the role of regional organizations such as ARPEL-the Association of Latin American State Oil Company Producers. 31 refs., 3 tabs.

    This data documentation discusses the procedures and methods used to measure total carbon dioxide concentration (TCO{sub 2}) and partial pressure of CO{sub 2} (pCO{sub 2}) in discrete water samples collected during three expeditions of the Research Vessel (R/V) Knorr in the South Pacific Ocean. Conducted as part of the World Ocean Circulation Experiment (WOCE), the first cruise (WOCE Section P16A/P17A) began in Papeete, Tahiti, French Polynesia, on October 6, 1992, and returned to Papeete on November 25, 1992. The second cruise (WOCE Section P17E/P19S) began in Papeete on December 4, 1992, and finished in Punta Arenas, Chile, on January 22, 1993. The third expedition (WOCE Section P19C) started in Punta Arenas, on February 22 and finished in Panama City, Panama, on April 13, 1993. During the three expeditions, 422 hydrographic stations were occupied. Hydrographic and chemical measurements made along WOCE Sections P16A/P17A, P17E/P19S, and P19C included pressure, temperature, salinity, and oxygen [measured by conductivity, temperature, and depth (CTD) sensor], as well as discrete measurements of salinity, oxygen, phosphate, nitrate, nitrite, silicate, chlorofluorocarbons (CFC-11, CFC-12), TCO{sub 2}, and pCO{sub 2} measured at 4 and 20 C. In addition, potential temperatures were calculated from the measured variables.

    Ciguatera poisoning, the most common type of fish poisoning in the world, has become a major public health problem in some parts of the South Pacific. This area has always been the site of periodic outbreaks, especially after severe storms or natural disasters that damage core reefs. But since World War II it has become evident that military activities and major construction projects that wreak havoc on corals also lead to ciguatera outbreaks. Extraordinarily high rates of ciguatera poisoning have occurred on the small Pacific islands that have been used for nuclear tests and on the islands that host the military infrastructures and activities that accompany the tests. This is true for both the Marshall Islands near Bikini and Eniwetok, where U.S. tests took place, and in French Polynesia, in the area around Moruroa Atoll where the French government continues to test. Ciguatera poisoning has a disastrous effect on people who depend on fishing as a way of life and on fish as the major source of protein. 10 refs.

    This paper reports that environmental concerns have leapt to the forefront of industry's concerns in operating in Latin America. The United Nations Conference on Environment and Development in Rio de Janeiro June 3-14 focused a strong world spotlight on the region's environmental and commercial resources. Protection of the region's rain forests, which accounts for a huge share of the world's total, is emerging as an especially contentious issue. Ecuador's Oriente region may well prove the litmus test of how or whether oil and gas companies are able to operate in Latin American rain forests. Controversy over industry operations in the Oriente have heated to the point that environmentalist and native groups have routinely picketed company offices in Quito and used mass fundraiser mailings in North America.

    ABSTRACT This paper describes a tool that will allow public health analysts to estimate infectious disease risk at the country level as a function of different international transportation modes. The prototype focuses on a cholera epidemic originating within Latin America or the Caribbean, but it can be expanded to consider other pathogens as well. This effort leverages previous work in collaboration with the Centers for Disease Control and Prevention to develop the International Travel to Community Impact (IT-CI) model, which analyzes and assesses potential international disease outbreaks then estimates the associated impacts to U.S. communities and the nation as a whole and orient it for use Outside the Continental United States (OCONUS). For brevity, we refer to this refined model as OIT-CI. First, we developed an operationalized meta-population spatial cholera model for Latin America and the Caribbean at the secondary administrative-level boundary. Secondly, we developed a robust function of human airline critical to approximating mixing patterns in the meta- population model. In the prototype version currently presented here, OIT-CI models a cholera epidemic originating in a Latin American or Caribbean country and spreading via airline transportation routes. Disease spread is modeled at the country level using a patch model with a connectivity function based on demographic, geospatial, and human transportation data. We have also identified data to estimate the water and health-related infrastructure capabilities of each country to include this potential impact on disease transmission.

    1999-01-01

    This project involves an open-ended, continuous process of information gathering with respect to Latin American and Caribbean environmental issues. This entails the development of contacts with individuals and institutions conducting research and work on issues of sustainability and environmental technology in the Americas. As part of this phase, a database containing information on firms, nongovernmental organizations (NGOs), governmental institutions, and other participants in Latin America's environmental sector was developed and is continually being updated. In addition, FIU-HCET's efforts were geared toward determining environmental technological needs in different parts of the region and identifying the most significant and lucrative markets. The project requires that FIU-HCET continually cement those contacts already established, continue updating the database to be made available to external users, and identify U.S. companies with the necessary expertise to participate in the Latin American and Caribbean markets. To aid in this endeavor, comprehensive, country-specific studies of the market for environmental goods and services are drafted and published by FIU-HCET. FIU-HCET, with sponsorship from OST, will make new, innovative, and more cost-effective technologies available for transfer throughout the Western Hemisphere. Environmental/energy technology development projects encompass the range of problems experienced by LACN. This includes mixed waste characterization and treatment, soils and groundwater remediation. In addition, future activities will include the issues of energy, climate change, and fossil fuels.

    This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO{sub 2}), discrete partial pressure of TCO{sub 2} (pCO{sub 2}), and total alkalinity (TALK), during the Research Vessel (R/V) Thomas Washington TUNES Leg 2 Expedition in the central South Pacific Ocean. Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Papeete, Tahiti, French Polynesia, on July 16, 1991, and returned to Papeete on August 25, 1991. WOCE Meridional Sections P17S along 135{degrees} W and P16S along 150{degrees} W were completed during the 40-day expedition. A total of 97 hydrographic stations were occupied. Hydrographic and chemical measurements made along WOCE Sections P17S and P16S included pressure, temperature, salinity, and oxygen measured by conductivity, temperature and depth sensor; bottle salinity; oxygen; phosphate; nitrate; nitrite; silicate; CFC-12; CFC- 11; TCO{sub 2}; TALK; and pCO{sub 2} measured at 20{degrees}C. The TCO{sub 2} concentration in 1000 seawater samples was determined with a coulometric analysis system, the pCO{sub 2} in 940 water samples was determined with an equilibrator/gas chromatograph system, while the TALK concentration in 139 samples was determined on shore at the laboratory of C. Goyet of Woods Hole Oceanographic Institution with an alkalinity titration system. In addition, 156 coulometric measurements for the Certified Reference Material (Batch {number_sign}6) were made and yielded a mean value of 2303.2 {plus_minus} 1.5 {mu}mol/kg. This mean value agrees within a standard deviation of the 2304.6 {plus_minus} 1.6 {mu}mol/kg (N=9) value determined with the manometer of C. D. Keeling at Scripps Institution of Oceanography (SIO). Replicate samples from 11 Niskin bottles at 4 stations were also collected for later shore-based reference analyses of TCO{sub 2} and TALK by vacuum extraction and manometry in the laboratory of C.

    1993-01-18

    A recent combination in South America of economic and geopolitical factors is prompting development of a new integrated gas-pipeline network in the continent's Southern Cone. The crucial factors include privatization, regional integration, economic growth, and environmental concerns. The area, Latin America's largest regional entity, includes Brazil (population 150 million and a 1990 GNP of about $375 billion, 9th largest in the world), Argentina (population 32 million and the third largest Latin American economy after Brazil and Mexico), Bolivia, Chile, Paraguay, and Uruguay. Argentina, Brazil, Paraguay, and Uruguay are members of the MercoSur economic bloc whose objective is to develop free trade in the region. There are very few integrated pipeline networks in the world. Besides the giant North American system, with hundreds of producers and pipelines, there is only one other large integrated network. It connects continental European countries to their outside suppliers such as Norway, the C.I.S., and Algeria. The emergence of a new pipeline system is therefore important for the natural-gas industry worldwide and even more so if it occurs in a region now growing rapidly after a decade of economic difficulties.

  7. Crafting regulations in emerging geothermal countries: The Peru example

    1996-12-31

    Conventional wisdom holds that no prudent investor or lender will ante up a penny of investment money in a geothermal project unless and until there is a geothermal resources law in place. Since every law depends on a regulatory regime to make the law work in actual practice, implemented regulations are equally important conditions precedent for geothermal development. In recognition of the importance of assisting geothermal regulatory development in the emerging geothermal countries of Latin America, during the 1995 to 1996 timeframe, the Geothermal Energy Association has acted in an advisory capacity to the Ministry of Energy and Mines of Peru, in the drafting of geothermal regulations for Peru. These regulations are designed to promote developmental investment in the geothermal resources of Peru, while simultaneously establishing reasonable standards for the protection of the people and the environment of the country. While these regulations are specific to Peru, they may well serve as a model for other countries of Latin America. Thus, the lessons learned in crafting the Peru regulatory regime may have applicability in other countries in which the geothermal industry is now working or may work in the future.

    NRECA conceived of the International Electric Cooperative Initiative on Energy Efficiency (IECIEE) in order to provide an ongoing means of contributing voluntary actions on greenhouse gas emissions mitigation as an integral component of its international programs and projects. This required designing the IECIEE to be integrated directly with the core interests and attributes of participating cooperatives in the U.S. and Latin America, which was the initial focus area selected for the IECIEE. In the case of NRECA International, the core interests related to promoting and strengthening the electric cooperative model, which has proved highly successful in maximizing operational efficiencies in electric power generation, distribution and retailing, as compared to government-owned entities. The approach involved three basic components: (i) establishing the IECIEE mechanism, which involved setting up a functioning organizational vehicle providing for investment, management, and emissions credit accounting; (ii) developing a portfolio of projects in countries where NRECA International could effectively implement the broader mandate of cooperative development as energy efficient suppliers and distributors of electrical energy; and (iii) conducting outreach to obtain the commitment of participants and resources from U.S. and Latin American cooperatives and partnering agencies in the development financing community.

    Central America encompasses seven small countries with strong disagreements, relatively large populations, and much foreign debt. It must meet the challenge of global progress while trying to master alternative sources of energy to substitute for oil, of which there is very little. The region has a total of 22-million inhabitants, four times that of Bolivia, but with only half the territory. The population density of El Salvador is the highest in Latin America and one of the highest in the world: 215 inhabitants per square kilometer. According to the Latin American Organization of Energy (OLADE), the region registers a high and growing participation of hydrocarbons in its energy consumption, based on the consolidated energy balance for the area. From the consumption distribution by sectors, it can be discerned that the transportation sector is the most critical. It has the highest growth rate, and consequently the projections derived therefrom are quite significant. This issue of Energy Detente includes the fuel price/tax series and the industrial fuel prices for September 1983 for countries of the Western Hemisphere.

    The next big frontier for oil and gas development will be the humid tropics, where more than 80% of exploration and production is expected to take place in the next decade. The tropical areas targeted by these operations not only hold large stores of oil and gas, but are also frequently undeveloped and remote, located in or near important and sensitive ecosystems. Within the tropics the most heavily targeted area is the Latin American Neotropics (New World tropics), which include South America, Mesoamerica and the Caribbean. A regionwide move toward privatization of state oil industries, growing liberalization of markets, and contractual incentives for foreign investment make this region a prime target for oil exploration and development. Proper evaluation of available technologies and planning will help determine how and where mitigation efforts should be directed to prevent and control environmental impacts.

    Approximately 1.6 billion people worldwide do not have access to electricity, and roughly 2.4 billion people rely on traditional biomass fuels to meet their heating and cooking needs. Lack of access to and use of energy - or energy poverty - has been recognized as a barrier to reaching the Millennium Development Goals (MDGs) and other targeted efforts to improve health and quality of life. Reducing reliance on traditional biomass can substantially reduce indoor air pollution-related morbidity and mortality; increasing access to lighting and refrigeration can improve educational and economic opportunities. Though targeted electrification efforts have had success within Latin America and East Asia (reaching electrification rates above 85%), sub-Saharan Africa has maintained electrification rates below 25% (IEA 2004).

    Greenhouse gas emissions from the forestry sector are estimated to be 8.4 GtCO2-eq./year or about 17percent of the global emissions. We estimate that the cost forreducing deforestation is low in Africa and several times higher in Latin America and Southeast Asia. These cost estimates are sensitive to the uncertainties of how muchunsustainable high-revenue logging occurs, little understood transaction and program implementation costs, and barriers to implementation including governance issues. Due to lack of capacity in the affected countries, achieving reduction or avoidance of carbon emissions will require extensive REDD-plus programs. Preliminary REDD-plus Readiness cost estimates and program descriptions for Indonesia, Democratic Republic of the Congo, Ghana, Guyana and Mexico show that roughly one-third of potential REDD-plus mitigation benefits might come from avoided deforestation and the rest from avoided forest degradation and other REDD-plus activities.

    Plans for worldwide pipeline construction into the next century increased in the past year, especially for developing regions of Latin America and Asia-Pacific. Many of the projects involve large capacity, international gas pipeline systems. By contrast, pipeline construction in Canada, The US, and Europe will decline. Those trends and others are revealed in the latest Oil and Gas Journal pipeline construction data, derived from a survey of world pipeline operators, industry sources, and published information. More than 61,000 miles of crude oil, product, and natural gas pipeline are to be built in 1995 and beyond. The paper discusses Europe's markets, North Sea pipelines, expansion of German pipeline, pipelines in the UK, European and African gas, the trans-Mediterranean gas pipeline, Caspian Sea pipeline, Middle East pipelines, Asia-Pacific activity, South American gas lines, pipelines in Colombia, TransCanada line, Gulf of Mexico pipelines, other Gulf activities, and other US activity.

    RAVEN is a generic software driver to perform parametric and probabilistic analysis of code simulating complex systems. Initially developed to provide dynamic risk analysis capabilities to the RELAP-7 code [1] is currently being generalized with the addition of Application Programming Interfaces (APIs). These interfaces are used to extend RAVEN capabilities to any software as long as all the parameters that need to be perturbed are accessible by inputs files or directly via python interfaces. RAVEN is capable to investigate the system response probing the input space using Monte Carlo, grid strategies, or Latin Hyper Cube schemes, but its strength is its focus toward system feature discovery like limit surfaces separating regions of the input space leading to system failure using dynamic supervised learning techniques. The paper will present an overview of the software capabilities and their implementation schemes followed by same application examples.

The General Cerri plant, under construction, is located in an area of 40,000 sq m with new installations to extract ethane and higher hydrocarbons. The design optimizes the extraction of hydrocarbons from the natural gas and recovers 76% of the ethane. Selection of the process resulted from an investigation that compared the system with processes that use water cooling and absorption with refrigerated oil.

    Operational reliability and low operational costs are becoming an important issue in Latin-American Industries. Programs promoting structural integrity and life assessment are becoming part of the strategies of industry to cope with increasingly competitive markets. However, structural integrity and life assessment is not all that is required to attain the goal of operational reliability; it is necessary to integrate in the assessment strategy the relationship between process variables, operational variables, maintenance, inspection, materials science and even instrument reliability. It is also important to take into account environmental regulations and personnel safety. A recent experimental program, aimed at developing and implementing a strategy which combines all the above mentioned aspects, has been undertaken. This article briefly describes an internal ``Guide for Operational Reliability`` developed as part of the program and discusses the Fitness-For-Service assessment of a cracked tower carried out during the first phase of the program.

    Polymer foam encapsulants provide mechanical, electrical, and thermal isolation in engineered systems. In fire environments, gas pressure from thermal decomposition of polymers can cause mechanical failure of sealed systems. In this work, a detailed uncertainty quantification study of PMDI-based polyurethane foam is presented to assess the validity of the computational model. Both experimental measurement uncertainty and model prediction uncertainty are examined and compared. Both the mean value method and Latin hypercube sampling approach are used to propagate the uncertainty through the model. In addition to comparing computational and experimental results, the importance of each input parameter on the simulation result is also investigated. These results show that further development in the physics model of the foam and appropriate associated material testing are necessary to improve model accuracy.

    Nuclear cooperation between Argentina and Brazil has been growing since the early 1980`s and as it grew, so did cooperation with the US Department of Energy (DOE). The Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) was formed in December 1991 to operate the Common System of Accounting and Control of Nuclear Materials (SCCC). In April 1994, ABACC and the DOE signed an Agreement of Cooperation in nuclear material safeguards. This cooperation has included training safeguards inspectors, exchanging nuclear material measurement and containment and surveillance technology, characterizing reference materials, and studying enrichment plant safeguards. The goal of the collaboration is to exchange technology, evaluate new technology in Latin American nuclear facilities, and strengthen regional safeguards. This paper describes the history of the cooperation, its recent activities, and future projects. The cooperation is strongly supported by all three governments: the Republics of Argentina and Brazil and the United States.

    There is a growing acceptance that the environmentalbenefits of forests extend beyond traditional ecological benefits andinclude the mitigation of climate change. Interest in forestry mitigationactivities has led to the inclusion of forestry practices at the projectlevel in international agreements. Climate change activities place newdemands on participating institutions to set baselines, establishadditionality, determine leakage, ensure permanence, and monitor andverify a project's greenhouse gas benefits. These issues are common toboth forestry and other types of mitigation projects. They demandempirical evidence to establish conditions under which such projects canprovide sustained long term global benefits.

    Agriculture in the arid and semi-arid regions that comprise much of present-day Peru, Bolivia, and Northern Chile is heavily dependent on irrigation; however, obtaining a dependable water supply in these areas is often difficult. The precolumbian peoples of Andean South America adapted to this situation by devising many strategies for transporting, storing, and retrieving water to insure consistent supply. I propose that the ''elaborated springs'' found at several Inka sites near Cuzco, Peru, are the visible expression of a simple and effective system of groundwater control and storage. I call this system ''geologic water storage'' because the water is stored in the pore spaces of sands, soils, and other near-surface geologic materials. I present two examples of sites in the Cuzco area that use this technology (Tambomachay and Tipon) and discuss the potential for identification of similar systems developed by other ancient Latin American cultures.

    The United Nations implements technical cooperation projects in developing countries through its Department of Technical Cooperation for Development (DTCD). The DTCD is mandated to explore for and develop natural resources (water, minerals, and relevant infrastructure) and energy - both conventional and new and renewable energy sources. To date, the United Nations has been involved in over 30 geothermal exploration projects (completed or underway) in 20 developing countries: 8 in Africa (Djibouti, Ethiopia, Kenya, Madagascar); 8 in Asia (China, India, Jordan, Philippines, Thailand); 9 in Latin America (Bolivia, Chile, El Salvador, Honduras, Mexico, Nicaragua, Panama) and 6 in Europe (Greece, Romania, Turkey, Yugoslavia). Today, the DTCD has seven UNDP geothermal projects in 6 developing countries. Four of these (Bolivia, China, Honduras, and Kenya) are major exploration projects whose formulation and execution has been possible thanks to the generous contributions under cost-sharing arrangements from the government of Italy. These four projects are summarized.

A detailed performance assessment (PA) for the WIPP was carried out in 1996 and supports an application by the DOE to the U.S. Environmental Protection Agency (EPA) for the certification of the WIPP for the disposal of TRU waste. The 1996 WIPP PA uses a computational structure that maintains a separation between stochastic (i.e., aleatory) and subjective (i.e., epistemic) uncertainty, with stochastic uncertainty arising from the many possible disruptions that could occur over the 10,000 yr regulatory period that applies to the WIPP and subjective uncertainty arising from the imprecision with which many of the quantities required in the PA are known. Important parts of this structure are (1) the use of Latin hypercube sampling to incorporate the effects of subjective uncertainty, (2) the use of Monte Carlo (i.e., random) sampling to incorporate the effects of stochastic uncertainty, and (3) the efficient use of the necessarily limited number of mechanistic calculations that can be performed to support the analysis. The use of Latin hypercube sampling generates a mapping from imprecisely known analysis inputs to analysis outcomes of interest that provides both a display of the uncertainty in analysis outcomes (i.e., uncertainty analysis) and a basis for investigating the effects of individual inputs on these outcomes (i.e., sensitivity analysis). The sensitivity analysis procedures used in the PA include examination of scatterplots, stepwise regression analysis, and partial correlation analysis. Uncertainty and sensitivity analysis results obtained as part of the 1996 WIPP PA are presented and discussed. Specific topics considered include two phase flow in the vicinity of the repository, radionuclide release from the repository, fluid flow and radionuclide

    Uncertainty and sensitivity analysis techniques based on Latin hypercube sampling, partial correlation analysis and stepwise regression analysis are used in an investigation with the MACCS model of the early health effects associated with a severe accident at a nuclear power station. The primary purpose of this study is to provide guidance on the variables to be considered in future review work to reduce the uncertainty in the important variables used in the calculation of reactor accident consequences. The effects of 34 imprecisely known input variables on the following reactor accident consequences are studied: number of early fatalities, number of cases of prodromal vomiting, population dose within 10 mi of the reactor, population dose within 1000 mi of the reactor, individual early fatality probability within 1 mi of the reactor, and maximum early fatality distance. When the predicted variables are considered collectively, the following input variables were found to be the dominant contributors to uncertainty: scaling factor for horizontal dispersion, dry deposition velocity, inhalation protection factor for nonevacuees, groundshine shielding factor for nonevacuees, early fatality hazard function alpha value for bone marrow exposure, and scaling factor for vertical dispersion.

    The worldwide LPG industry continues to expand faster than the petroleum industry -- 4%/year for LPG vs. 2%/year for petroleum in 1995 and less than 1%/year in the early 1990s. This rapid expansion of LPG markets is occurring in virtually every region of the world, including such developing countries as China. The Far East is the focus of much of the LPG industry`s attention, but many opportunities exist in other regions such as the Indian subcontinent, Southeast Asia, and Latin America. The investment climate is improving in all phases of downstream LPG marketing, including terminaling, storage, and wholesale and retail distribution. The world LPG supply/demand balance has been relatively tight since the Gulf War and should remain so. Base demand (the portion of demand that is not highly price-sensitive) is expanding more rapidly than supplies. As a result, the proportion of total LPG supplies available for price-sensitive petrochemical feedstock markets is declining, at least in the short term. The paper discusses importers, price patterns, world LPG demand, world LPG supply, US NGL supply, US gas processing, ethane and propane supply, butane, isobutane, and natural gasoline supply, and US NGL demand.

    Recent years have witnessed a growing recognition of the link between emissions of carbon dioxide (CO{sub 2}) and changes in the global climate. Of all anthropogenic activities, energy production and use generate the single largest portion of these greenhouse gases. Although developing countries currently account for a small share of global carbon emissions, their contribution is increasing rapidly. Due to the rapid expansion of energy demand in these nations, the developing world`s share in global modern energy use rose from 16 to 27 percent between 1970 and 1990. If the growth rates observed over the past 20 years persist energy demand in developing will surpass that in the countries of the Organization for Economic Cooperation and Development (OECD) early in the 21st century. The study seeks to examine the forces that galvanize the growth of energy use and carbon emissions, to assess the likely future levels of energy and CO{sub 2} in selected developing nations and to identify opportunities for restraining this growth. The purpose of this report is to provide the quantitative information needed to develop effective policy options, not to identify the options themselves. These individual studies were conducted fro Argentina, Brazil, Mexico and Venezuela in Latin America.

    In this issue, Energy Detente draws from their regular Western and Eastern Hemisphere Fuel Price/Tax Series, each produced monthly, and adds other survey data and analysis for a broad view of 48 countries around the world. They find that seven Latin American nations, including OPEC members Venezuela and Ecuador, are among the ten countries with lowest gasoline prices. In this Fourth Special Price Report, Energy Detente provides a first-time presentation of which prices are government-controlled, and which are free to respond to market forces. South Korea, with fixed prices since 1964, has the highest premium-grade gasoline price in our survey, US $5.38 per gallon. Paraguay, with prices fixed by PETROPAR, the national oil company, has the second highest premium gasoline price, US $4.21 per gallon. Nicaragua, also with government price controls, ranks third highest in the survey, with US $3.38 per gallon for premium gasoline. Kuwait shows the lowest price at US $0.55 per gallon. Several price changes from the previous survey reflect changes in currency exchange as all prices are converted to US dollars. The Energy Detente fuel price/tax series is presented for Western Hemisphere countries.

    Argentina has the most-advanced nuclear technology in Latin America, but budget cuts have slowed down some projects. Potential hydroelectric power is sufficient to fill Argentina's electrical needs, but the Yacireta complex, a joint venture with Paraguay, will be completed almost two years behind schedule. There is plenty of coal in Argentina, but it needs to import coal and coke to produce cast iron and steel. Geothermal and wind energy represent viable alternatives, but more funds and research are needed to exploit their potential. Argentina is on the road to energy independence, but with a new constitutional government possible in 1984, a shift in national energy policy is also possible. Any resultant increase in petroleum consumption to fuel rapid industrial development and stimulate employment could turn Argentina back into an oil-importing Third World nation. The Energy Detente fuel price/tax series and the principal industrial-fuel prices for December 1982 are included for the countries of the Western Hemisphere.

    RAVEN is a generic software framework to perform parametric and probabilistic analysis based on the response of complex system codes. The initial development was aimed to provide dynamic risk analysis capabilities to the Thermo-Hydraulic code RELAP-7 [], currently under development at the Idaho National Laboratory. Although the initial goal has been fully accomplished, RAVEN is now a multi-purpose probabilistic and uncertainty quantification platform, capable to agnostically communicate with any system code. This agnosticism has been employed by providing Application Programming Interfaces (APIs). These interfaces are used to allow RAVEN to interact with any code as long as all the parameters that need to be perturbed are accessible by inputs files or via python interfaces. RAVEN is capable to investigate the system response, investigating the input space using Monte Carlo, Grid, or Latin Hyper Cube sampling schemes, but its strength is focused toward system feature discovery, such as limit surfaces, separating regions of the input space leading to system failure, using dynamic supervised learning techniques. The paper presents an overview of the software capabilities and their implementation schemes followed by some application examples.

    A RELAP5-3D model of the ITER (Latin for the way ) vacuum vessel (VV) primary heat transfer system has been developed to evaluate a proposed design change that relocates the heat exchangers (HXs) from the exterior of the tokamak building to the interior. This alternative design protects the HXs from external hazards such as wind, tornado, and aircraft crash. The proposed design integrates the VV HXs into a VV pressure suppression system (VVPSS) tank that contains water to condense vapour in case of a leak into the plasma chamber. The proposal is to also use this water as the ultimate sink when removing decay heat from the VV system. The RELAP5-3D model has been run under normal operating and abnormal (decay heat) conditions. Results indicate that this alternative design is feasible, with no effects on the VVPSS tank under normal operation and with tank temperature and pressure increasing under decay heat conditions resulting in a requirement to remove steam generated if the VVPSS tank low pressure must be maintained.

    This paper reports that oil and gas companies in the US are curbing costs and redirecting spending to survive the worst decline of petroleum industry activity on record. Persistently weak US natural gas prices and shaky oil prices worldwide have put pressure on domestic companies to become low cost producers. Efforts to cut exploration and development costs have depressed activity in the US, one of the world's most mature oil and gas provinces. International E and D hot spots include the UK North Sea, Yemen, Thailand, Myanmar, Pakistan, and Latin America. Prospects in the Commonwealth of Independent States also continue to generate considerable enthusiasm. Operators struggling to survive or searching for funds to spend on non-US prospects are trying to shuck noncore US assets. Other favored cost cutting strategies include reducing and restructuring debt, operating and administrative staffs, and internal organizations. Major integrated companies are able to add value by refocusing refining, petrochemical, or marketing operations. But independents must adapt operations close to the wellhead to become low cost producers. Whatever tactics are used to mitigate effects of low US activity, no domestic company --- from the largest integrated major to the smallest independent producer --- has proven to be immune from the downturn.

    PECOS is a computational library for creating and manipulating realizations of stochastic quantities, including scalar uncertain variables, random fields, and stochastic processes. It offers a unified interface to univariate and multivariate polynomial approximations using either orthogonal or interpolation polynomials; numerical integration drivers for Latin hypercube sampling, quadrature, cubature, and sparse grids; and fast Fourier transforms using third party libraries. The PECOS core also offers statistical utilities and transformations between various representations of stochastic uncertainty. PECOSmore » provides a C++ API through which users can generate and transform realizations of stochastic quantities. It is currently used by Sandia’s DAKOTA, Stokhos, and Encore software packages for uncertainty quantification and verification. PECOS generates random sample sets and multi-dimensional integration grids, typically used in forward propagation of scalar uncertainty in computational models (uncertainty quantification (UQ)). PECOS also generates samples of random fields (RFs) and stochastic processes (SPs) from a set of user-defined power spectral densities (PSDs). The RF/SP may be either Gaussian or non-Gaussian and either stationary or nonstationary, and the resulting sample is intended for run-time query by parallel finite element simulation codes. Finally, PECOS supports nonlinear transformations of random variables via the Nataf transformation and extensions.« less

    In the last 10 years, the power generation market has seen radical changes. The coming years will see yet more change. Although the pace of change may be uneven across Europe, it is clear that the old reference points for the power generation market are no longer valid. Along with other market players, Shell has re-evaluated the role it wishes to play in the power generation market. Although it has long operated large generation capacity on its own sites, Shell's role has been that of a fuel supplier to monopoly power generation and distribution organizations, which were largely state controlled . Privatization and liberalization have been followed by changing market structures tending to push risk towards the producer. This evolution presents challenges for the normal IPP structure, where market risk is transferred and offers an opportunity for the active participation of the fuel supplier in meeting these challenges. In 1996, Shell decided to embrace the changes in power generation market. Already, significant steps have been taken in markets in Asia, Latin America and in Europe. The differing requirements of each of these markets means there are no standard solutions and requires Shell to devise flexible frameworks which meet the customer's needs. Shell is bringing its significant strengths to the power generation market and looks forward to participating on a world wide scale in the industry at this exciting phase in its development.

    This perspective provides an overview of wood pellet markets in a number of countries of high significance, together with an inventory of market factors and relevant past or existing policies. In 2010, the estimated global wood pellet production and consumption were close to 14.3 Mt (million metric tonnes) and 13.5 Mt, respectively, while the global installed production capacity had reached over 28 Mt. Two types of pellets are mainly traded (i) for residential heating and (ii) for large-scale district heating or co-fi ring installations. The EU was the primary market, responsible for nearly 61% and 85% of global production and consumption, respectively in 2010. EU markets were divided according to end use: (i) residential and district heating, (ii) power plants driven market, (iii) mixed market, and (iv) export-driven countries. North America basically serves as an exporter, but also with signifi cant domestic consumption in USA. East Asia is predicted to become the second-largest consumer after the EU in the near future. The development perspective in Latin America remains unclear. Five factors that determine the market characteristics are: (i) the existence of coal-based power plants, (ii) the development of heating systems, (iii) feedstock availability, (iv) interactions with wood industry, and (v) logistics factor. Furthermore, intervention policies play a pivotal role in market development. The perspective of wood pellets industry was also analyzed from four major aspects: (i) supply potential, (ii) logistics issues, (iii) sustainability considerations, and (iv) technology development.

    Over 80% of rural Navajos and about two-thirds of all Navajos use scarce woodfuel and low-grade coal for home heating half the year, with coal used mainly as a nighttime adjunct. Serious health problems arise because stoves are old and leak smoke and carbon monoxide. The impacts are gender-biased to women and small children. Respiratory disease is a major cause of Navajo mortality and unusually high admissions to Navajo Indian Health Service hospitals. A 1990 study at a Navajo hospital showed that Navajo children under two years of age from homes with woodstoves are nearly five times more likely to contract acute lower respiratory tract infections than children from homes with no stove. Correctives include improved stoves and fuels. Our previous studies on clean-burning starchy/cellulosic {open_quotes}rootfuels{close_quotes} in Latin America, Africa, and Asia are applicable. We discuss our preliminary work on the Navajo reservation, the current status of household stoves and stovefuels, the health impacts of woodsmoke and coalsmoke from old, faulty stoves, the conditions for growing rootfuel on the reservation, and policy and strategy for coping with the problem.

    Monitoring vegetation is an active area of laser-induced fluorescence imaging (LIFI) research. The Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU) is assisting in the transfer of the LIFI technology to the agricultural private sector through a market survey. The market survey will help identify the key eco-agricultural issues of the nations that could benefit from the use of sensor technologies developed by the Office of Science and Technology (OST). The principal region of interest is the Western Hemisphere, particularly, the rapidly growing countries of Latin America and the Caribbean. The analysis of needs will assure that the focus of present and future research will center on economically important issues facing both hemispheres. The application of the technology will be useful to the agriculture industry for airborne crop analysis as well as in the detection and characterization of contaminated sites by monitoring vegetation. LIFI airborne and close-proximity systems will be evaluated as stand-alone technologies and additions to existing sensor technologies that have been used to monitor crops in the field and in storage.

    The crucial oil-market issue for this year`s second half is new supply. Production will increase again outside the Organization of Petroleum Exporting Countries. And Iraq has general approval to resume exports under limits set by the United Nations, although start of the exports has been delayed by at least 60 days. The big question is the market`s ability to absorb the supply gains. As usual, the market`s need for oil in the second half will depend on economies. So far in 1996, economic growth has pushed consumption to levels unexpected a year ago. Demand the rest of the year depends heavily on economic performances of the industrialized nations that make up the organization for Economic Cooperation and Development (OECD) and the rapidly growing nations of the Asia-Pacific region. Growth in countries elsewhere in the developing world, especially Latin America, remains a wild card. The paper discusses the worldwide outlook, crude oil prices, US product prices, natural gas prices, US economy, US energy demand, natural gas in the US, US oil demand, gasoline prices, distillate gains, resid slumps, LPG, ethane, US supply, production patterns, rise in refinery capacity, imports, stocks, and stock coverage.

Led by Saudi Arabia, the Middle East will produce nearly 26 million metric tons of LPG in million metric tons of LPG in 1996, more than 54% of the world`s almost 48 million metric tons of export LPG. In 2000, however, with world exports of LPG expanding to 58.9 million metric tons, Middle East suppliers; share will have remained flat, making up 31.7 million metric tons, or 53.9%. Saudi Arabia`s contribution will exceed 15 million metric tons, reflecting essentially no growth since 1995. These and other patterns, from data compiled by Purvin and Gertz, Dallas, and published earlier this year, show other suppliers of LPG, especially African (Algeria/Nigeria), North Sea, and Latin American (Venezuela/Argentina), picking up larger shares in the last 5 years of this decade. This scenario assumes completion of several major supply projects that are either panned, under construction, or nearing start up in most of these areas. The paper discusses the global picture, the supply situation in the Middle East, Africa, the North Sea, and South America.

    A Level II/III probabilistic risk assessment (PRA) has been performed for N Reactor, a Department of Energy (DOE) production reactor located on the Hanford reservation in Washington. The accident progression analysis documented in this report determines how core damage accidents identified in the Level I PRA progress from fuel damage to confinement response and potential releases the environment. The objectives of the study are to generate accident progression data for the Level II/III PRA source term model and to identify changes that could improve plant response under accident conditions. The scope of the analysis is comprehensive, excluding only sabotage and operator errors of commission. State-of-the-art methodology is employed based largely on the methods developed by Sandia for the US Nuclear Regulatory Commission in support of the NUREG-1150 study. The accident progression model allows complex interactions and dependencies between systems to be explicitly considered. Latin Hypecube sampling was used to assess the phenomenological and systemic uncertainties associated with the primary and confinement system responses to the core damage accident. The results of the analysis show that the N Reactor confinement concept provides significant radiological protection for most of the accident progression pathways studied.

    Highlights: Black-Right-Pointing-Pointer We established Trypanosoma cruzi lacking the gene for carbamoyl phosphate synthetase II. Black-Right-Pointing-Pointer Disruption of the cpsII gene significantly reduced the growth of epimastigotes. Black-Right-Pointing-Pointer In particular, the CPSII-null mutant severely retarded intracellular growth. Black-Right-Pointing-Pointer The de novo pyrimidine pathway is critical for the parasite growth in the host cell. -- Abstract: The intracellular parasitic protist Trypanosoma cruzi is the causative agent of Chagas disease in Latin America. In general, pyrimidine nucleotides are supplied by both de novo biosynthesis and salvage pathways. While epimastigotes-an insect form-possess both activities, amastigotes-an intracellular replicating form of T. cruzi-are unable to mediate the uptake of pyrimidine. However, the requirement of de novo pyrimidine biosynthesis for parasite growth and survival has not yet been elucidated. Carbamoyl-phosphate synthetase II (CPSII) is the first and rate-limiting enzyme of the de novo biosynthetic pathway, and increased CPSII activity is associated with the rapid proliferation of tumor cells. In the present study, we showed that disruption of the T. cruzicpsII gene significantly reduced parasite growth. In particular, the growth of amastigotes lacking the cpsII gene was severely suppressed. Thus, the de novo pyrimidine pathway is important for proliferation of T. cruzi in the host cell cytoplasm and represents a promising target for chemotherapy against Chagas disease.

    Performance assessments for the Area 5 Radioactive Waste Management Site on the Nevada Test Site have used three different mathematical models to estimate Rn-222 flux density. This study describes the performance, uncertainty, and sensitivity of the three models which include the U.S. Nuclear Regulatory Commission Regulatory Guide 3.64 analytical method and two numerical methods. The uncertainty of each model was determined by Monte Carlo simulation using Latin hypercube sampling. The global sensitivity was investigated using Morris one-at-time screening method, sample-based correlation and regression methods, the variance-based extended Fourier amplitude sensitivity test, and Sobol's sensitivity indices. The models were found to produce similar estimates of the mean and median flux density, but to have different uncertainties and sensitivities. When the Rn-222 effective diffusion coefficient was estimated using five different published predictive models, the radon flux density models were found to be most sensitive to the effective diffusion coefficient model selected, the emanation coefficient, and the radionuclide inventory. Using a site-specific measured effective diffusion coefficient significantly reduced the output uncertainty. When a site-specific effective-diffusion coefficient was used, the models were most sensitive to the emanation coefficient and the radionuclide inventory.

  9. ITER Fusion Energy

    ITER (in Latin ?the way?) is designed to demonstrate the scientific and technological feasibility of fusion energy. Fusion is the process by which two light atomic nuclei combine to form a heavier over one and thus release energy. In the fusion process two isotopes of hydrogen ? deuterium and tritium ? fuse together to form a helium atom and a neutron. Thus fusion could provide large scale energy production without greenhouse effects; essentially limitless fuel would be available all over the world. The principal goals of ITER are to generate 500 megawatts of fusion power for periods of 300 to 500 seconds with a fusion power multiplication factor, Q, of at least 10. Q ? 10 (input power 50 MW / output power 500 MW). The ITER Organization was officially established in Cadarache, France, on 24 October 2007. The seven members engaged in the project ? China, the European Union, India, Japan, Korea, Russia and the United States ? represent more than half the world?s population. The costs for ITER are shared by the seven members. The cost for the construction will be approximately 5.5 billion Euros, a similar amount is foreseen for the twenty-year phase of operation and the subsequent decommissioning.

    Over a 12 month period, a fire PRA was developed for a DOE facility using the NUREG/CR-6850 EPRI/NRC fire PRA methodology. The fire PRA modeling included calculation of fire severity factors (SFs) and fire non-suppression probabilities (PNS) for each safe shutdown (SSD) component considered in the fire PRA model. The SFs were developed by performing detailed fire modeling through a combination of CFAST fire zone model calculations and Latin Hypercube Sampling (LHS). Component damage times and automatic fire suppression system actuation times calculated in the CFAST LHS analyses were then input to a time-dependent model of fire non-suppression probability. The fire non-suppression probability model is based on the modeling approach outlined in NUREG/CR-6850 and is supplemented with plant specific data. This paper presents the methodology used in the DOE facility fire PRA for modeling fire-induced SSD component failures and includes discussions of modeling techniques for: • Development of time-dependent fire heat release rate profiles (required as input to CFAST), • Calculation of fire severity factors based on CFAST detailed fire modeling, and • Calculation of fire non-suppression probabilities.

    Foster Wheeler Power Systems Inc., and its partners--Petrox SA Refineria de Petroleo and Empresa Nacional de Petroleo (ENAP), the Chilean national oil company--closed on the financing of Petropower Energia Limitada, a $237 million financed combination delayed coker-cogeneration facility. The facility is now under construction adjacent to Petrox`s 84,000 b/d Talcahuano refinery, near Concepcion. In addition to the low interest rate of 7.36%--only 170 basis points over the 10 year US Treasury yield--the project was rated investment-grade by Standard and Poor`s. The Petropower project also has the distinction of having the longest term--18 years--for any project financing in Latin America. The project is unique in other ways: it is the Republic of Chile`s first public/private partnership and also the first project to combine petroleum coking technology with cogeneration technology in a single project financing. The paper discusses risk assumption, the Petropower project, organization, delayed coker facility, hydrotreater unit, cogeneration facility, environmental assessment, Chile`s changing market, and project benefit.

    The author presents a summary of the structure and program of the US Export Council for Renewable Energy (US/ECRE). This organization was founded in 1982 as a consortium of US renewable energy trade associations, and is the non-profit/industry counterpart of CORECT. It serves to accelerate the diffusion of sustainable renewable energy services worldwide, and to enhance US industry`s position in this expanded marketplace. The projected energy growth in the next 20 years is expected to favor developing countries. Barriers in the way of renewable energy development include technology awareness, financing and risk reception, policy decisions, and institutional barriers. The industrial team hopes to address this problem through several different programs: strategic alliances; end-user outreach; industry market development; policy/project development; financing and facilitation. The program involves several phases: first, market conditioning; second, regional conferences and exhibitions; third, follow-up and implementation. There are currently four major focus areas for US effort: Latin America and the Caribbean; southern Africa; Asia; Russia and the FSU. The status of programs addressed toward these markets is described in more detail.

    Reducing cost is a critical challenge facing environmental remediation today. One of the most effective ways of reducing costs is to improve decision-making. This can range from choosing more cost- effective remediation alternatives (for example, determining whether a groundwater contamination plume should be remediated or not) to improving data collection (for example, determining when data collection should stoop). Uncertainty in site conditions presents a major challenge for effective decision-making. We present a framework for increasing the effectiveness of remedial design decision-making at groundwater contamination sites where there is uncertainty in many parameters that affect remediation design. The objective is to provide an easy-to-use economic framework for making remediation decisions. The presented framework is used to 1) select the best remedial design from a suite of possible ones, 2) estimate if additional data collection is cost-effective, and 3) determine the most important parameters to be sampled. The framework is developed by combining elements from Latin-Hypercube simulation of contaminant transport, economic risk-cost-benefit analysis, and Regional Sensitivity Analysis (RSA).

    Printed circuit heat exchanger (PCHE) is recently considered as a recuperator for the high temperature gas cooled reactor. In this work, the zigzag-channels of a PCHE have been optimized by using three-dimensional Reynolds-Averaged Navier-Stokes (RANS) analysis and response surface approximation (RSA) modeling technique to enhance thermal-hydraulic performance. Shear stress transport turbulence model is used as a turbulence closure. The objective function is defined as a linear combination of the functions related to heat transfer and friction loss of the PCHE, respectively. Three geometric design variables viz., the ratio of the radius of the fillet to hydraulic diameter of the channels, the ratio of wavelength to hydraulic diameter of the channels, and the ratio of wave height to hydraulic diameter of the channels, are used for the optimization. Design points are selected through Latin-hypercube sampling. The optimal design is determined through the RSA model which uses RANS derived calculations at the design points. The results show that the optimum shape enhances considerably the thermal-hydraulic performance than a reference shape. (authors)

    2013-07-01

    We present a physics-based methodology for quantifying the uncertainty in a given quantity of interest (QOI) that is contributed by uncertainties in opacities in radiation transport problems. Typically, opacities are tabulated as a function of density, temperature, and photon energy group. The size of this table makes a study of uncertainties at this level challenging because of the well-known 'curse of dimensionality.' We address this by studying uncertain parameters in the underlying physical model that generates the opacity tables. At this level, there are fewer uncertain parameters but still too many to analyze directly through computationally expensive radiation transport simulations. In order to explore this large uncertain parameter space, we develop two simplified radiation transport problems that are much less computationally demanding than the target problem of interest. An emulator is created for each QOI for each simplified problem using Bayesian Multivariate Adaptive Regression Splines (BMARS). This emulator is used to create a functional relationship between the QOIs and the uncertain parameters. Sensitivity analysis is performed using the emulator to determine which parameters contribute significantly to the uncertainty. This physics-based screening process reduces the dimension of the parameter space that is then studied via the computationally expensive radiation transport calculation to generate distributions of quantities of interest. Results of this research demonstrate that the QOIs for the target problem agree for varying screening criteria determined by the sensitivity analysis, and the QOIs agree well for varying Latin Hypercube Design (LHD) sample sizes for the uncertain space.

    On February 6, 1987 the US Department of Energy (DOE) awarded the final phase of the decontamination and decommissioning of the nuclear and reactor facilities at the Center for Energy and Environmental Research (CEER), in Mayaguez, Puerto Rico. Bechtel National, Inc., was made the decontamination and decommissioning (D and D) contractor. The goal of the project was to enable DOE to proceed with release of the CEER facility for use by the University of Puerto Rico, who was the operator. This presentation describes that project and lesson learned during its progress. The CEER facility was established in 1957 as the Puerto Rico Nuclear Center, a part of the Atoms for Peace Program. It was a nuclear training and research institution with emphasis on the needs of Latin America. It originally consisted of a 1-megawatt Materials Testing Reactor (MTR), support facilities and research laboratories. After eleven years of operation the MTR was shutdown and defueled. A 2-megawatt TRIGA reactor was installed in 1972 and operated until 1976, when it woo was shutdown. Other radioactive facilities at the center included a 10-watt homogeneous L-77 training reactor, a natural uranium graphite-moderated subcritical assembly, a 200KV particle accelerator, and a 15,000 Ci Co-60 irradiation facility. Support facilities included radiochemistry laboratories, counting rooms and two hot cells. As the emphasis shifted to non-nuclear energy technology a name change resulted in the CEER designation, and plans were started for the decontamination and decommissioning effort.

    2014-07-30

    This presentation provides an overview of emulation, calibration and experiment design for computer experiments. Emulation refers to building a statistical surrogate from a carefully selected and limited set of model runs to predict unsampled outputs. The standard kriging approach to emulation of complex computer models is presented. Calibration refers to the process of probabilistically constraining uncertain physics/engineering model inputs to be consistent with observed experimental data. An initial probability distribution for these parameters is updated using the experimental information. Markov chain Monte Carlo (MCMC) algorithms are often used to sample the calibrated parameter distribution. Several MCMC algorithms commonly employed in practice are presented, along with a popular diagnostic for evaluating chain behavior. Space-filling approaches to experiment design for selecting model runs to build effective emulators are discussed, including Latin Hypercube Design and extensions based on orthogonal array skeleton designs and imposed symmetry requirements. Optimization criteria that further enforce space-filling, possibly in projections of the input space, are mentioned. Designs to screen for important input variations are summarized and used for variable selection in a nuclear fuels performance application. This is followed by illustration of sequential experiment design strategies for optimization, global prediction, and rare event inference.

    World pipeline construction planned in 1994 and beyond has fallen in the past year, reflecting uncertainties in energy markets. Still, significant expansions are under way or planned for Latin America, Asia and the Pacific regions, and Europe. Latest Oil and Gas Journal data, derived from its survey of world pipeline operators, industry sources, and published information, show more than 55,000 miles of crude oil, product, and natural gas pipeline planned for 1994 and beyond. The data include projections for pipeline construction in Russia and former republics of the Soviet Union. Western Russia and all countries west of the Ural Mountains are included under totals for Europe, eastern Russia and countries east of the Urals under totals for the Asia-Pacific region. The paper discusses the following: European gas lines; North Sea projects; Gulf of Thailand; Yacheng subsea pipeline; Australian gas lines; other Asian lines; Russian activity; Algeria-Europe gas lines; Southeast US; Gulf gathering systems; Western US; South America; Trans-Ecuadorian expansion; Chilean gas network; and Bolivia-Brazil gas line.

    The Metropolitan Region of Sao Paulo (Brazil) has a population 16.322 million people (1995 estimate) living in an area of 8,051 km2 with most of them concentrated in the city of Sao Paulo with 9.8 million people and 4.6 million cars. Although with an air quality better than some other Latin American megacities such as Mexico and Santiago do Chile, the air quality still exceeds the national air quality standards. In 2/17/1993 Brazilian Petroleum Company (PETROBRAS) and the Bolivian Petroleum Company (Yacimientos Petroliferos Fiscales Bolivianos -- YPFB) signed an agreement to bring natural gas from Bolivia to the south and southeast of Brazil. The end of the construction of the gas pipeline will be in 1999, and it will deliver 4 million Nm3/day of natural gas to COMGAS Sao Paulo State Gas Company. This amount will increase to 8.1 million Nm3/day by the year 2006, that will be sufficient to supply the Sao Paulo Metropolitan Region market need at that time. In this study an estimate of the influence in the air quality was performed supposing the substitution of fuel oil by natural gas in industry and also in diesel buses. The results showed that there will be benefits in relation to sulfur dioxide, PM10, greenhouse gases and trace elements, and negligible effects in relation to NO{sub x}, NMTOC and carbon monoxide.

    We compare two approaches for building a statistical proxy model (metamodel) for CO₂ geologic sequestration from the results of full-physics compositional simulations. The first approach involves a classical Box-Behnken or Augmented Pairs experimental design with a quadratic polynomial response surface. The second approach used a space-filling maxmin Latin Hypercube sampling or maximum entropy design with the choice of five different meta-modeling techniques: quadratic polynomial, kriging with constant and quadratic trend terms, multivariate adaptive regression spline (MARS) and additivity and variance stabilization (AVAS). Simulations results for CO₂ injection into a reservoir-caprock system with 9 design variables (and 97 samples) were used to generate the data for developing the proxy models. The fitted models were validated with using an independent data set and a cross-validation approach for three different performance metrics: total storage efficiency, CO₂ plume radius and average reservoir pressure. The Box-Behnken–quadratic polynomial metamodel performed the best, followed closely by the maximin LHS–kriging metamodel.

    A study was made of some of the main traffic hubs in a Latin American metropolis, in order to determine the presence or absence of noise by means of noise measurements and acoustic mapping. To characterize noise in the evaluated road stretches, 232 measurements were taken at different points. The Predictor software package was used for the noise mapping calculations. Noise sensitive areas, e.g., hospitals, were identified in the evaluated road stretches. Noise maps were calculated for two hospitals, showing the current levels of noise that reach their facades. Hypothetical scenarios were simulated by making changes in the composition of traffic and total number of vehicles, and an assessment was made of the potential influence of these modifications in reducing the noise levels reaching the facades of the buildings in question. The simulations indicated that a 50% reduction in total traffic flow, or a 50% reduction in heavy vehicle traffic flow, would reduce the noise levels by about 3 dB(A). - Highlights: • Evaluation of noise pollution in urban traffic hubs • Street systems • Environmental noise impacts • Noise mapping.

    The Middle East will continue to play the dominant role of a petroleum supplier in the world oil market in the year 2000, according to business-as-usual forecasts published by the US Department of Energy. However, interesting trade patterns will emerge as a result of the democratization in the Soviet Union and Eastern Europe. US petroleum imports will increase from 46% in 1989 to 49% in 2000. A significantly higher level of US petroleum imports (principally products) will be coming from Japan, the Soviet Union, and Eastern Europe. Several regions, the Far East, Japan, Latin American, and Africa will import more petroleum. Much uncertainty remains about of the level future Soviet crude oil production. USSR net petroleum exports will decrease; however, the United States and Canada will receive some of their imports from the Soviet Union due to changes in the world trade patterns. The Soviet Union can avoid becoming a net petroleum importer as long as it (1) maintains enough crude oil production to meet its own consumption and (2) maintains its existing refining capacities. Eastern Europe will import approximately 50% of its crude oil from the Middle East.

    In January of this year, Venezuela captured the attention of the international energy community by welcoming back the foreign oil companies that, 20 years earlier, it had shut out of the country by nationalizing the hydrocarbon sector. The tool used to attract that attention, a new exploration bidding round, is the most publicized event staged to date in the country`s aperture process. However, it is only the latest in a series of steps taken by officials to bring international oil and gas companies back to Caracas. Venezuela`s physical attraction is easily understood. The country possesses roughly one-half of Latin America`s (including Mexico) 125 billion bbl of established, conventional crude oil reserves, plus an estimated 300 billion bbl of additional, nonconventional reserves in the ultra-heavy crude belt of the Orinoco basin. Averaging 2.8 million bpd in 1996, Venezuelan crude production represents over 35% of regional oil output. Natural gas reserves total 138 Tcf, or just over one-half of the region`s total reserves of 274 Tcfg. Annual gas output averages just under 5 Tcf, of which roughly 30% is reinjected as part of tertiary oil recovery schemes. This paper reviews the incentives, deregulation, and government policies to restore the oil and gas industry to the country.

    This report identifies the most important results of a comparative analysis of household commercial energy use in Venezuelan urban cities. The use of modern fuels is widespread among all cities. Cooking consumes the largest share of urban household energy use. The survey documents no use of biomass and a negligible use of kerosene for cooking. LPG, natural gas, and kerosene are the main fuels available. LPG is the fuel choice of low-income households in all cities except Maracaibo, where 40% of all households use natural gas. Electricity consumption in Venezuela`s urban households is remarkably high compared with the levels used in households in comparable Latin American countries and in households of industrialized nations which confront harsher climatic conditions and, therefore, use electricity for water and space heating. The penetration of appliances in Venezuela`s urban households is very high. The appliances available on the market are inefficient, and there are inefficient patterns of energy use among the population. Climate conditions and the urban built form all play important roles in determining the high level of energy consumption in Venezuelan urban households. It is important to acknowledge the opportunities for introducing energy efficiency and conservation in Venezuela`s residential sector, particularly given current economic and financial constraints, which may hamper the future provision of energy services.

They are also mutually beneficial for fostering positive relationships with other governments and private industry, and demonstrate that responsible end-of-life options are given to legacy U.S.-origin sources in other countries. GTRI/OSRP does not take back sources that have a viable path for commercial disposal. Most US origin sources were sold commercially and were not provided by the US government. Below is a synopsis of cooperative efforts with Brazil, Ecuador, and Uruguay. Bilateral and multilateral efforts have been successful in removing hundreds of U.S.origin sealed radioactive sources from Latin American countries to the U.S. As many disused sources remain in the region, and since repatriation is not always an option, GTRI will continue to work with those countries to ensure that these sources are stored securely for the long-term. Successful Latin America operations should serve as a model for other regional cooperation in the repatriation of sealed sources, encouraging other source exporting countries to implement similar programs. Securing and removing sources, both domestically and internationally, is crucial to strengthening the life-cycle management of radioactive sources worldwide. Such efforts not only prevent these materials from being used maliciously, but also address public health and safety concerns, and under-gird the IAEA Code of Conduct on the Safety and Security of Radioactive Sources.

Its main goal is to create a multi-purpose platform for the deploying of all the capabilities needed for Probabilistic Risk Assessment, uncertainty quantification, data mining analysis and optimization studies. RAVEN is currently equipped with three different sampling categories: Forward samplers (Monte Carlo, Latin Hyper Cube, Stratified, Grid Sampler, Factorials, etc.), Adaptive Samplers (Limit Surface search, Adaptive Polynomial Chaos, etc.) and Dynamic Event Tree (DET) samplers (Deterministic and Adaptive Dynamic Event Trees). The main subject of this document is to report the activities that have been done in order to: start the migration of the RAVEN/RELAP-7 control logic system into MOOSE, and develop advanced dynamic sampling capabilities based on the Dynamic Event Tree approach. In order to provide to all MOOSE-based applications a control logic capability, in this Fiscal Year an initial migration activity has been initiated, moving the control logic system, designed for RELAP-7 by the RAVEN team, into the MOOSE framework. In this document, a brief explanation of what has been done is going to be reported. The second and most important subject of this report is about the development of a Dynamic Event Tree (DET) sampler named “Hybrid Dynamic Event Tree” (HDET) and its Adaptive variant “Adaptive Hybrid Dynamic Event Tree” (AHDET). As other authors have already reported, among the different types of uncertainties, it is possible to discern two principle types: aleatory and epistemic uncertainties. The classical Dynamic Event Tree is in charge of treating the first class (aleatory) uncertainties; the dependence of the probabilistic risk assessment and analysis on the epistemic uncertainties are treated by an initial Monte Carlo sampling (MCDET). From each Monte Carlo sample, a DET analysis is run (in total, N trees). The Monte Carlo employs a pre-sampling of the

    A methodology for using the MELCOR code with the Latin Hypercube Sampling method was developed to estimate uncertainty in various predicted quantities such as hydrogen generation or release of fission products under severe accident conditions. In this case, the emphasis was on estimating the range of hydrogen sources in station blackout conditions in the Sequoyah Ice Condenser plant, taking into account uncertainties in the modeled physics known to affect hydrogen generation. The method uses user-specified likelihood distributions for uncertain model parameters, which may include uncertainties of a stochastic nature, to produce a collection of code calculations, or realizations, characterizing the range of possible outcomes. Forty MELCOR code realizations of Sequoyah were conducted that included 10 uncertain parameters, producing a range of in-vessel hydrogen quantities. The range of total hydrogen produced was approximately 583kg 131kg. Sensitivity analyses revealed expected trends with respected to the parameters of greatest importance, however, considerable scatter in results when plotted against any of the uncertain parameters was observed, with no parameter manifesting dominant effects on hydrogen generation. It is concluded that, with respect to the physics parameters investigated, in order to further reduce predicted hydrogen uncertainty, it would be necessary to reduce all physics parameter uncertainties similarly, bearing in mind that some parameters are inherently uncertain within a range. It is suspected that some residual uncertainty associated with modeling complex, coupled and synergistic phenomena, is an inherent aspect of complex systems and cannot be reduced to point value estimates. The probabilistic analyses such as the one demonstrated in this work are important to properly characterize response of complex systems such as severe accident progression in nuclear power plants.

    Highlights: Black-Right-Pointing-Pointer Literature of WEEE generation in developing countries is reviewed. Black-Right-Pointing-Pointer We analyse existing estimates of WEEE generation for Brazil. Black-Right-Pointing-Pointer We present a model for WEEE generation estimate. Black-Right-Pointing-Pointer WEEE generation of 3.77 kg/capita year for 2008 is estimated. Black-Right-Pointing-Pointer Use of constant lifetime should be avoided for non-mature market products. - Abstract: Sales of electrical and electronic equipment are increasing dramatically in developing countries. Usually, there are no reliable data about quantities of the waste generated. A new law for solid waste management was enacted in Brazil in 2010, and the infrastructure to treat this waste must be planned, considering the volumes of the different types of electrical and electronic equipment generated. This paper reviews the literature regarding estimation of waste electrical and electronic equipment (WEEE), focusing on developing countries, particularly in Latin America. It briefly describes the current WEEE system in Brazil and presents an updated estimate of generation of WEEE. Considering the limited available data in Brazil, a model for WEEE generation estimation is proposed in which different methods are used for mature and non-mature market products. The results showed that the most important variable is the equipment lifetime, which requires a thorough understanding of consumer behavior to estimate. Since Brazil is a rapidly expanding market, the 'boom' in waste generation is still to come. In the near future, better data will provide more reliable estimation of waste generation and a clearer interpretation of the lifetime variable throughout the years.

    Uncertainty and sensitivity analysis techniques based on Latin hypercube sampling, partial correlation analysis and stepwise regression analysis are used in an investigation with the MACCS model of the food pathways associated with a severe accident at a nuclear power station. The primary purpose of this study is to provide guidance on the variables to be considered in future review work to reduce the uncertainty in the important variables used in the calculation of reactor accident consequences. The effects of 87 imprecisely-known input variables on the following reactor accident consequences are studied: crop growing season dose, crop long-term dose, milk growing season dose, total food pathways dose, total ingestion pathways dose, total long-term pathways dose, area dependent cost, crop disposal cost, milk disposal cost, condemnation area, crop disposal area and milk disposal area. When the predicted variables are considered collectively, the following input variables were found to be the dominant contributors to uncertainty: fraction of cesium deposition on grain fields that is retained on plant surfaces and transferred directly to grain, maximum allowable ground concentrations of Cs-137 and Sr-90 for production of crops, ground concentrations of Cs-134, Cs-137 and I-131 at which the disposal of milk will be initiated due to accidents that occur during the growing season, ground concentrations of Cs-134, I-131 and Sr-90 at which the disposal of crops will be initiated due to accidents that occur during the growing season, rate of depletion of Cs-137 and Sr-90 from the root zone, transfer of Sr-90 from soil to legumes, transfer of Cs-137 from soil to pasture, transfer of cesium from animal feed to meat, and the transfer of cesium, iodine and strontium from animal feed to milk.

The primary purpose of this study is to provide guidance on the variables to be considered in future review work to reduce the uncertainty in the important variables used in the calculation of reactor accident consequences. The effects of 75 imprecisely known input variables on the following reactor accident consequences are studied: crop growing season dose, crop long-term dose, water ingestion dose, milk growing season dose, long-term groundshine dose, long-term inhalation dose, total food pathways dose, total ingestion pathways dose, total long-term pathways dose, total latent cancer fatalities, area-dependent cost, crop disposal cost, milk disposal cost, population-dependent cost, total economic cost, condemnation area, condemnation population, crop disposal area and milk disposal area. When the predicted variables are considered collectively, the following input variables were found to be the dominant contributors to uncertainty: dry deposition velocity, transfer of cesium from animal feed to milk, transfer of cesium from animal feed to meat, ground concentration of Cs-134 at which the disposal of milk products will be initiated, transfer of Sr-90 from soil to legumes, maximum allowable ground concentration of Sr-90 for production of crops, fraction of cesium entering surface water that is consumed in drinking water, groundshine shielding factor, scale factor defining resuspension, dose reduction associated with decontamination, and ground concentration of 1-131 at which disposal of crops will be initiated due to accidents that occur during the growing season.

    Sensitivity analysis (SA) is a commonly used approach for identifying important parameters that dominate model behaviors. We use a newly developed software package, a Problem Solving environment for Uncertainty Analysis and Design Exploration (PSUADE), to evaluate the effectiveness and efficiency of ten widely used SA methods, including seven qualitative and three quantitative ones. All SA methods are tested using a variety of sampling techniques to screen out the most sensitive (i.e., important) parameters from the insensitive ones. The Sacramento Soil Moisture Accounting (SAC-SMA) model, which has thirteen tunable parameters, is used for illustration. The South Branch Potomac River basin near Springfield, West Virginia in the U.S. is chosen as the study area. The key findings from this study are: (1) For qualitative SA methods, Correlation Analysis (CA), Regression Analysis (RA), and Gaussian Process (GP) screening methods are shown to be not effective in this example. Morris One-At-a-Time (MOAT) screening is the most efficient, needing only 280 samples to identify the most important parameters, but it is the least robust method. Multivariate Adaptive Regression Splines (MARS), Delta Test (DT) and Sum-Of-Trees (SOT) screening methods need about 400–600 samples for the same purpose. Monte Carlo (MC), Orthogonal Array (OA) and Orthogonal Array based Latin Hypercube (OALH) are appropriate sampling techniques for them; (2) For quantitative SA methods, at least 2777 samples are needed for Fourier Amplitude Sensitivity Test (FAST) to identity parameter main effect. McKay method needs about 360 samples to evaluate the main effect, more than 1000 samples to assess the two-way interaction effect. OALH and LPτ (LPTAU) sampling techniques are more appropriate for McKay method. For the Sobol' method, the minimum samples needed are 1050 to compute the first-order and total sensitivity indices correctly. These comparisons show that qualitative SA methods are more efficient

    We present multi-model global datasets of nitrogen and sulfate deposition covering time periods from 1850 to 2100, calculated within the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP). The computed deposition fluxes are compared to surface wet deposition and ice-core measurements. We use a new dataset of wet deposition for 2000-2002 based on critical assessment of the quality of existing regional network data. We show that for present-day (year 2000 ACCMIP time-slice), the ACCMIP results perform similarly to previously published multi-model assessments. The analysis of changes between 1980 and 2000 indicates significant differences between model and measurements over the United States, but less so over Europe. This difference points towards misrepresentation of 1980 NH3 emissions over North America. Based on ice-core records, the 1850 deposition fluxes agree well with Greenland ice cores but the change between 1850 and 2000 seems to be overestimated in the Northern Hemisphere for both nitrogen and sulfur species. Using the Representative Concentration Pathways to define the projected climate and atmospheric chemistry related emissions and concentrations, we find large regional nitrogen deposition increases in 2100 in Latin America, Africa and parts of Asia under some of the scenarios considered. Increases in South Asia are especially large, and are seen in all scenarios, with 2100 values more than double 2000 in some scenarios and reaching >1300 mgN/m2/yr averaged over regional to continental scale regions in RCP 2.6 and 8.5, ~30-50% larger than the values in any region currently (2000). Despite known issues, the new ACCMIP deposition dataset provides novel, consistent and evaluated global gridded deposition fields for use in a wide range of climate and ecological studies.

    This paper describes the convergence of MELCOR Accident Consequence Code System, Version 2 (MACCS2) probabilistic results of offsite consequences for the uncertainty analysis of the State-of-the-Art Reactor Consequence Analyses (SOARCA) unmitigated long-term station blackout scenario at the Peach Bottom Atomic Power Station. The consequence metrics evaluated are individual latent-cancer fatality (LCF) risk and individual early fatality risk. Consequence results are presented as conditional risk (i.e., assuming the accident occurs, risk per event) to individuals of the public as a result of the accident. In order to verify convergence for this uncertainty analysis, as recommended by the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards, a ‘high’ source term from the original population of Monte Carlo runs has been selected to be used for: (1) a study of the distribution of consequence results stemming solely from epistemic uncertainty in the MACCS2 parameters (i.e., separating the effect from the source term uncertainty), and (2) a comparison between Simple Random Sampling (SRS) and Latin Hypercube Sampling (LHS) in order to validate the original results obtained with LHS. Three replicates (each using a different random seed) of size 1,000 each using LHS and another set of three replicates of size 1,000 using SRS are analyzed. The results show that the LCF risk results are well converged with either LHS or SRS sampling. The early fatality risk results are less well converged at radial distances beyond 2 miles, and this is expected due to the sparse data (predominance of “zero” results).

  1. Evaluating climate models: Should we use weather or climate observations?

    Calling the numerical models that we use for simulations of climate change 'climate models' is a bit of a misnomer. These 'general circulation models' (GCMs, AKA global climate models) and their cousins the 'regional climate models' (RCMs) are actually physically-based weather simulators. That is, these models simulate, either globally or locally, daily weather patterns in response to some change in forcing or boundary condition. These simulated weather patterns are then aggregated into climate statistics, very much as we aggregate observations into 'real climate statistics'. Traditionally, the output of GCMs has been evaluated using climate statistics, as opposed to their ability to simulate realistic daily weather observations. At the coarse global scale this may be a reasonable approach, however, as RCM's downscale to increasingly higher resolutions, the conjunction between weather and climate becomes more problematic. We present results from a series of present-day climate simulations using the WRF ARW for domains that cover North America, much of Latin America, and South Asia. The basic domains are at a 12 km resolution, but several inner domains at 4 km have also been simulated. These include regions of complex topography in Mexico, Colombia, Peru, and Sri Lanka, as well as a region of low topography and fairly homogeneous land surface type (the U.S. Great Plains). Model evaluations are performed using standard climate analyses (e.g., reanalyses; NCDC data) but also using time series of daily station observations. Preliminary results suggest little difference in the assessment of long-term mean quantities, but the variability on seasonal and interannual timescales is better described. Furthermore, the value-added by using daily weather observations as an evaluation tool increases with the model resolution.

    In this paper we investigate CO2 emission scenarios for Colombia and the effects of implementing carbon taxes and abatement targets on the energy system. By comparing baseline and policy scenario results from two integrated assessment partial equilibrium models TIAM-ECN and GCAM and two general equilibrium models Phoenix and MEG4C, we provide an indication of future developments and dynamics in the Colombian energy system. Currently, the carbon intensity of the energy system in Colombia is low compared to other countries in Latin America. However, this trend may change given the projected rapid growth of the economy and the potential increase in the use of carbon-based technologies. Climate policy in Colombia is under development and has yet to consider economic instruments such as taxes and abatement targets. This paper shows how taxes or abatement targets can achieve significant CO2 reductions in Colombia. Though abatement may be achieved through different pathways, taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand-side responses. The electric power sector plays an important role in achieving CO2 emission reductions in Colombia, through the increase of hydropower, the introduction of wind technologies, and the deployment of biomass, coal and natural gas with CO2 capture and storage (CCS). Uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low-carbon technologies. This paper also assesses the economy-wide implications of mitigation policies such as potential losses in GDP and consumption. As a result, an assessment of the legal, institutional, social and environmental barriers to economy-wide mitigation policies is critical yet beyond the scope of this paper.

    As co-products, agricultural and forestry residues represent a potential low cost, low carbon, source for bioenergy. A method is developed method for estimating the maximum sustainable amount of energy potentially available from agricultural and forestry residues by converting crop production statistics into associated residue, while allocating some of this resource to remain on the field to mitigate erosion and maintain soil nutrients. Currently, we estimate that the world produces residue biomass that could be sustainably harvested and converted into over 50 EJ yr-1 of energy. The top three countries where this resource is estimated to be most abundant are currently net energy importers: China, the United States (US), and India. The global potential from residue biomass is estimated to increase to approximately 80-95 EJ yr-1 by mid- to late- century, depending on physical assumptions such as of future crop yields and the amount of residue sustainably harvestable. The future market for biomass residues was simulated using the Object-Oriented Energy, Climate, and Technology Systems Mini Climate Assessment Model (ObjECTS MiniCAM). Utilization of residue biomass as an energy source is projected for the next century under different climate policy scenarios. Total global use of residue biomass is estimated to increase to 70-100 EJ yr-1 by mid- to late- century in a central case, depending on the presence of a climate policy and the economics of harvesting, aggregating, and transporting residue. Much of this potential is in developing regions of the world, including China, Latin America, Southeast Asia, and India.

We created a general multi-scale, multi-host stochastic SEIR epidemiological network model, with both short and long-range movement, to simulate the spread of an infectious disease through Nigerian human, poultry, backyard duck, and wild bird populations. We chose parameter ranges specific to avian influenza (but not to a particular strain) and used a Latin hypercube sample experimental design to investigate epidemic predictions in a thousand simulations. We ranked the risk of local regions by the number of times they became infected in the ensemble of simulations. These spatial statistics were then complied into a potential risk map of infection. Finally, we validated the results with a known outbreak, using spatial analysis of all the simulation runs to show the progression matched closely with the observed location of the farms infected in the 2006-2007 epidemic.« less

    Construction of the Republic of Chile`s first public/private industrial partnership project is well under way. Ground was broken for the $232-million Petropower Energia Limitada project early this year, shortly after the final contract between the parties - Foster Wheeler Power Systems, Inc. (FWPS); Petrox S.A. Refineria de Petroleo and Empresa Nacional del Petroleo (ENAP) - was signed. The Petropower project, located adjacent to Petrox`s 84,000-b/d refinery in Talcahuano, represents the first project ever to combine petroleum coking technology with cogeneration technology in a single project financing. Petropower is 85% owned by FWPS, 7.5% by ENAP, the Chilean national oil company and parent of Petrox S.A. When completed in mid-1998, the Petropower project will enable Petrox to refine heavier crudes and enhance the refinery`s flexibility and economics. The project will consist of a delayed coking facility (a 12,000-b/d delayed coking unit and a 7,000-b/d hydrotreating plant) and a 67-MW (59 MW net) cogeneration plant. The coke produced will fuel a Foster Wheeler proprietary-design circulating fluidized-bed (CFB) boiler which will generate all the high-pressure steam and electric power needs of the Petrox refinery. This unit will be the first circulating fluidized-bed boiler to be built in Latin America. The cogeneration facility, using limestone as a reagent and equipped with a baghouse, will control SO{sub x} emissions from combustion of the green coke fuel and easily meet all Chilean environmental standards. Moreover, by constructing the cogeneration facility, Petrox will not have to proceed with capital improvements to existing facilities to ensure a reliable source of steam and electricity, resulting in substantial savings for Petrox. The cogeneration plant provides a permanent {open_quotes}disposal{close_quotes} for all coke produced by the delayed coker, thereby solving any future problems of unwanted or excess coke.

    The increasing scarcity of conventional crude oil resources, as well as the sharply higher prices of crude oil, will generate increased interest in heavy oil, tar sands, and oil shale as potential substitutes. For all of these unconventional oil resources, extraction will be much more difficult, time consuming, and costly than for conventional crude oil. Although the inplace resources are vast and exist in many areas including the United States, the USSR, western Europe, Canada, and Latin America, probably only a small fraction of the inplace resources will prove to be economically extractable. These unconventional oil resources are now being developed in several locations around the world, and depending upon the exact definition probably account for less than 1 percent of current world oil supplies. The major current developments include: Canadian tar sands. Heavy oil production at Yarega in the Komi Autonomous Republic in the Soviet Union. The USSR also burns shale for power generation in Estonia. Venezuelan production of heavy oil in the Orinoco Heavy Oil Belt is currently about 15,000 b/d. Oil shale is likely to prove much less important than heavy oil and tar sands over the next 20 years. Further development of these unconventional resources is planned, and many projects are under way or under study. On the basis of current planning, world output of heavy oils and oil from tar sands and shale will be unlikely to exceed 2 million b/d by 1990, roughly five time today's level. However, both of these resources will require the development of new technologies for any large increases in output above what is now planned. The bulk of Canada's tar sands exists at great depths and will require the development of in situ processes for extraction. In the Orinoco, heavy metals contained in the oil make it difficult to refine with existing technology.

    The Idaho National Engineering and Environmental Laboratory is being used as a temporary storage facility for transuranic waste generated by the U.S. Nuclear Weapons program at the Rocky Flats Plant (RFP) in Golden, Colorado. Currently, there is a large effort in progress to prepare to ship this waste to the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. In order to meet the TRU Waste Characterization Quality Assurance Program Plan nondestructive assay compliance requirements and quality assurance objectives, it is necessary to determine the total uncertainty of the radioassay results produced by the Stored Waste Examination Pilot Plant (SWEPP) Passive Active Neutron (PAN) radioassay system. To this end a modified statistical sampling and verification approach has been developed to determine the total uncertainty of a PAN measurement. In this approach the total performance of the PAN nondestructive assay system is simulated using computer models of the assay system and the resultant output is compared with the known input to assess the total uncertainty. This paper is one of a series of reports quantifying the results of the uncertainty analysis of the PAN system measurements for specific waste types and measurement modes. In particular this report covers passive mode measurements of weapons grade plutonium-contaminated graphite molds contained in 208 liter drums (waste code 300). The validity of the simulation approach is verified by comparing simulated output against results from measurements using known plutonium sources and a surrogate graphite waste form drum. For actual graphite waste form conditions, a set of 50 cases covering a statistical sampling of the conditions exhibited in graphite wastes was compiled using a Latin hypercube statistical sampling approach.

    Highlights: Black-Right-Pointing-Pointer Review of the different e-waste collection systems and recycling processes. Black-Right-Pointing-Pointer We present the e-waste collection systems used in Europe and in the US. Black-Right-Pointing-Pointer We present e-waste collection systems used in Asia and Latin America. Black-Right-Pointing-Pointer E-waste management between developed and developing countries is very different. Black-Right-Pointing-Pointer We made a comparison of the world situation to the current Brazilian reality. - Abstract: Recycling and the related issue of sustainable development are increasing in importance around the world. In Brazil, the new National Policy on Solid Wastes has prompted discussion on the future of electronic waste (e-waste). Over the last 10 years, different e-waste collection systems and recycling processes have been applied globally. This paper presents the systems used in different countries and compares the world situation to the current Brazilian reality. To establish a recycling process, it is necessary to organize efficient collection management. The main difficulty associated with the implementation of e-waste recycling processes in Brazil is the collection system, as its efficiency depends not only on the education and cooperation of the people but also on cooperation among industrial waste generators, distributors and the government. Over half a million waste pickers have been reported in Brazil and they are responsible for the success of metal scrap collection in the country. The country also has close to 2400 companies and cooperatives involved in recycling and scrap trading. On the other hand, the collection and recycling of e-waste is still incipient because e-wastes are not seen as valuable in the informal sector. The Brazilian challenge is therefore to organize a system of e-waste management including the informal sector without neglecting environmentally sound management principles.

    Sensitivity analysis (SA) is a commonly used approach for identifying important parameters that dominate model behaviors. We use a newly developed software package, a Problem Solving environment for Uncertainty Analysis and Design Exploration (PSUADE), to evaluate the effectiveness and efficiency of ten widely used SA methods, including seven qualitative and three quantitative ones. All SA methods are tested using a variety of sampling techniques to screen out the most sensitive (i.e., important) parameters from the insensitive ones. The Sacramento Soil Moisture Accounting (SAC-SMA) model, which has thirteen tunable parameters, is used for illustration. The South Branch Potomac River basin nearmore » Springfield, West Virginia in the U.S. is chosen as the study area. The key findings from this study are: (1) For qualitative SA methods, Correlation Analysis (CA), Regression Analysis (RA), and Gaussian Process (GP) screening methods are shown to be not effective in this example. Morris One-At-a-Time (MOAT) screening is the most efficient, needing only 280 samples to identify the most important parameters, but it is the least robust method. Multivariate Adaptive Regression Splines (MARS), Delta Test (DT) and Sum-Of-Trees (SOT) screening methods need about 400–600 samples for the same purpose. Monte Carlo (MC), Orthogonal Array (OA) and Orthogonal Array based Latin Hypercube (OALH) are appropriate sampling techniques for them; (2) For quantitative SA methods, at least 2777 samples are needed for Fourier Amplitude Sensitivity Test (FAST) to identity parameter main effect. McKay method needs about 360 samples to evaluate the main effect, more than 1000 samples to assess the two-way interaction effect. OALH and LPτ (LPTAU) sampling techniques are more appropriate for McKay method. For the Sobol' method, the minimum samples needed are 1050 to compute the first-order and total sensitivity indices correctly. These comparisons show that qualitative SA methods are more

    The next great issue on the Russian landscape will be management of its foreign debt. In the near future the United States will be called upon to lead an international program of debt restructuring to assist Russia in overcoming the burden of its debt trap. With debt service obligations equal to 50{percent} of 1999 revenues, Russia has virtually no chance of sustaining a program of economic recovery without debt relief (Hardt, 1999). With some form of debt restructuring a foregone conclusion, Russia, the United States, and world community have a vital stake in searching for creative ways to transform the inevitability of debt restructuring into something of value and constructive to Russia and the problems it faces. This was the rationale behind debt-for-nature swaps which emerged in the early 1980s in Latin American and Eastern Europe as a means of relieving developing nations of their crippling foreign debt. Debt-for-nature swaps served both domestic and international needs by converting a portion of foreign debt, often at steep discounts, into local currency that was then used to fund programs to preserve the environment. The debt swap mechanism provides the prospect of getting something of real value where nothing is expected. The Pacific Northwest National Laboratory (PNNL) has proposed to use the same model to synergistically capitalize defense threat reduction activities and environmental remediation within Russia's closed nuclear cities. Preventing the emigration of nuclear technology, expertise, and hardware from these cities to subnational groups and countries of proliferation concern is one of the world's foremost pressing problems. It is in the best national security interest of the United states to assist Russia in overcoming the legacy of the Cold War by helping to address the catastrophic environmental and public health effects of nuclear production that negatively impact economic stabilization.

    The use of parameterized reduced order models(PROMs) within the stochastic reduced order model (SROM) framework is a logical progression for both methods. In this report, five different parameterized reduced order models are selected and critiqued against the other models along with truth model for the example of the Brake-Reuss beam. The models are: a Taylor series using finite difference, a proper orthogonal decomposition of the the output, a Craig-Bampton representation of the model, a method that uses Hyper-Dual numbers to determine the sensitivities, and a Meta-Model method that uses the Hyper-Dual results and constructs a polynomial curve to better represent the output data. The methods are compared against a parameter sweep and a distribution propagation where the first four statistical moments are used as a comparison. Each method produces very accurate results with the Craig-Bampton reduction having the least accurate results. The models are also compared based on time requirements for the evaluation of each model where the Meta- Model requires the least amount of time for computation by a significant amount. Each of the five models provided accurate results in a reasonable time frame. The determination of which model to use is dependent on the availability of the high-fidelity model and how many evaluations can be performed. Analysis of the output distribution is examined by using a large Monte-Carlo simulation along with a reduced simulation using Latin Hypercube and the stochastic reduced order model sampling technique. Both techniques produced accurate results. The stochastic reduced order modeling technique produced less error when compared to an exhaustive sampling for the majority of methods.

    In this paper we investigate CO2 emission scenarios for Colombia and the effects of implementing carbon taxes and abatement targets on the energy system. By comparing baseline and policy scenario results from two integrated assessment partial equilibrium models TIAM-ECN and GCAM and two general equilibrium models Phoenix and MEG4C, we provide an indication of future developments and dynamics in the Colombian energy system. Currently, the carbon intensity of the energy system in Colombia is low compared to other countries in Latin America. However, this trend may change given the projected rapid growth of the economy and the potential increase inmore » the use of carbon-based technologies. Climate policy in Colombia is under development and has yet to consider economic instruments such as taxes and abatement targets. This paper shows how taxes or abatement targets can achieve significant CO2 reductions in Colombia. Though abatement may be achieved through different pathways, taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand-side responses. The electric power sector plays an important role in achieving CO2 emission reductions in Colombia, through the increase of hydropower, the introduction of wind technologies, and the deployment of biomass, coal and natural gas with CO2 capture and storage (CCS). Uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low-carbon technologies. This paper also assesses the economy-wide implications of mitigation policies such as potential losses in GDP and consumption. As a result, an assessment of the legal, institutional, social and environmental barriers to economy-wide mitigation policies is critical yet beyond the scope of this paper.« less

    Since the beginning of the last decade three Latin American countries that operate research reactors - Argentina, Brazil and Chile - have been joining efforts to improve the regional capability in the management of spent fuel elements from the TRIGA and MTR reactors operated in the region. A main drive in this initiative, sponsored by the International Atomic Energy Agency, is the fact that no definite solution regarding the back end of the research reactor fuel cycle has been taken by any of the participating country. However, any long-term solution - either disposition in a repository or storage away from reactor - will involve at some stage the transportation of the spent fuel through public roads. Therefore, a licensed cask that provides adequate shielding, assurance of subcriticality, and conformance to internationally accepted safety, security and safeguards regimes is considered a strategic part of any future solution to be adopted at a regional level. As a step in this direction, a packaging for the transport of irradiated fuel for MTR and TRIGA research reactors was designed by the tri-national team and a half-scale model equipped with the MTR version of the internal basket was constructed in Argentina and Brazil and tested in Brazil. Three test campaigns have been carried out so far, covering both normal conditions of transportation and hypothetical accident conditions. After failing the tests in the first two test series, the specimen successfully underwent the last test sequence. A second specimen, incorporating the structural improvements in view of the previous tests results, will be tested in the near future. Numerical simulations of the free drop and thermal tests are being carried out in parallel, in order to validate the computational modeling that is going to be used as a support for the package certification.

    The National Risk Assessment Partnership (NRAP) consists of 5 U.S DOE national laboratories collaborating to develop a framework for predicting the risks associated with carbon sequestration. The approach taken by NRAP is to divide the system into components, including injection target reservoirs, wellbores, natural pathways including faults and fractures, groundwater and the atmosphere. Next, develop a detailed, physics and chemistry-based model of each component. Using the results of the detailed models, develop efficient, simplified models, termed reduced order models (ROM) for each component. Finally, integrate the component ROMs into a system model that calculates risk profiles for the site. This report details the development of the Groundwater Geochemistry ROM for the Edwards Aquifer at PNNL. The Groundwater Geochemistry ROM for the Edwards Aquifer uses a Wellbore Leakage ROM developed at LANL as input. The detailed model, using the STOMP simulator, covers a 5x8 km area of the Edwards Aquifer near San Antonio, Texas. The model includes heterogeneous hydraulic properties, and equilibrium, kinetic and sorption reactions between groundwater, leaked CO2 gas, brine, and the aquifer carbonate and clay minerals. Latin Hypercube sampling was used to generate 1024 samples of input parameters. For each of these input samples, the STOMP simulator was used to predict the flux of CO2 to the atmosphere, and the volume, length and width of the aquifer where pH was less than the MCL standard, and TDS, arsenic, cadmium and lead exceeded MCL standards. In order to decouple the Wellbore Leakage ROM from the Groundwater Geochemistry ROM, the response surface was transformed to replace Wellbore Leakage ROM input parameters with instantaneous and cumulative CO2 and brine leakage rates. The most sensitive parameters proved to be the CO2 and brine leakage rates from the well, with equilibrium coefficients for calcite and dolomite, as well as the number of illite and kaolinite

    The U.S. Department of Energy Manual DOE M 435.1-1, Radioactive Waste Management Manual, requires that performance assessments demonstrate that releases of radionuclides to the environment are as low as reasonably achievable (ALARA). Quantitative cost benefit analysis of radiation protection options is one component of the ALARA process. This report summarizes a quantitative cost benefit analysis of closure cover thickness for the Area 5 Radioactive Waste Management Site (RWMS) on the Nevada Test Site. The optimum cover thickness that maintains doses ALARA is shown to be the thickness with the minimum total closure cost. Total closure cost is the sum of cover construction cost and the health detriment cost. Cover construction cost is estimated based on detailed cost estimates for closure of the 92-acre Low-Level Waste Management Unit (LLWMU). The health detriment cost is calculated as the product of collective dose and a constant monetary value of health detriment in units of dollars per unit collective dose. Collective dose is the sum of all individual doses in an exposed population and has units of person-sievert (Sv). Five discrete cover thickness options ranging from 2.5 to 4.5 meters (m) (8.2 to 15 feet [ft]) are evaluated. The optimization was subject to the constraints that (1) options must meet all applicable regulatory requirements and that (2) individual doses be a small fraction of background radiation dose. Total closure cost is found to be a monotonically increasing function of cover thickness for the 92-ac LLWMU, the Northern Expansion Area, and the entire Area 5 RWMS. The cover construction cost is orders of magnitude greater than the health detriment cost. Two-thousand Latin hypercube sampling realizations of the relationship between total closure cost and cover thickness are generated. In every realization, the optimum cover thickness is 2.5 m (8.2 ft) for the 92-ac Low-Level Waste Management Unit, the Northern Expansion Area, and the entire Area

    RAVEN is a generic software framework to perform parametric and probabilistic analysis based on the response of complex system codes. The initial development was aimed to provide dynamic risk analysis capabilities to the Thermo-Hydraulic code RELAP-7, currently under development at the Idaho National Laboratory (INL). Although the initial goal has been fully accomplished, RAVEN is now a multi-purpose probabilistic and uncertainty quantification platform, capable to agnostically communicate with any system code. This agnosticism includes providing Application Programming Interfaces (APIs). These APIs are used to allow RAVEN to interact with any code as long as all the parameters that need to be perturbed are accessible by inputs files or via python interfaces. RAVEN is capable of investigating the system response, and investigating the input space using Monte Carlo, Grid, or Latin Hyper Cube sampling schemes, but its strength is focused toward system feature discovery, such as limit surfaces, separating regions of the input space leading to system failure, using dynamic supervised learning techniques. The development of RAVEN has started in 2012, when, within the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program, the need to provide a modern risk evaluation framework became stronger. RAVEN principal assignment is to provide the necessary software and algorithms in order to employ the concept developed by the Risk Informed Safety Margin Characterization (RISMC) program. RISMC is one of the pathways defined within the Light Water Reactor Sustainability (LWRS) program. In the RISMC approach, the goal is not just the individuation of the frequency of an event potentially leading to a system failure, but the closeness (or not) to key safety-related events. Hence, the approach is interested in identifying and increasing the safety margins related to those events. A safety margin is a numerical value quantifying the probability that a safety metric (e.g. for

    RAVEN, under the support of the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program [1], is advancing its capability to perform statistical analyses of stochastic dynamic systems. This is aligned with its mission to provide the tools needed by the Risk Informed Safety Margin Characterization (RISMC) path-lead [2] under the Department Of Energy (DOE) Light Water Reactor Sustainability program [3]. In particular this task is focused on the synergetic development with the RELAP-7 [4] code to advance the state of the art on the safety analysis of nuclear power plants (NPP). The investigation of the probabilistic evolution of accident scenarios for a complex system such as a nuclear power plant is not a trivial challenge. The complexity of the system to be modeled leads to demanding computational requirements even to simulate one of the many possible evolutions of an accident scenario (tens of CPU/hour). At the same time, the probabilistic analysis requires thousands of runs to investigate outcomes characterized by low probability and severe consequence (tail problem). The milestone reported in June of 2013 [5] described the capability of RAVEN to implement complex control logic and provide an adequate support for the exploration of the probabilistic space using a Monte Carlo sampling strategy. Unfortunately the Monte Carlo approach is ineffective with a problem of this complexity. In the following year of development, the RAVEN code has been extended with more sophisticated sampling strategies (grids, Latin Hypercube, and adaptive sampling). This milestone report illustrates the effectiveness of those methodologies in performing the assessment of the probability of core damage following the onset of a Station Black Out (SBO) situation in a boiling water reactor (BWR). The first part of the report provides an overview of the available probabilistic analysis capabilities, ranging from the different types of distributions available, possible sampling

    This slim book (166 pages) shines a spotlight on pre-industrial African metallurgy, its global connections, and anthropological implications. It integrates seemingly disparate disciplines, such as history, geology, ethnography, archeology, and metallurgy, to illustrate the diversity and innovation in metallurgy across Africa and the role of metals in the rise of socio-economic inequalities and political power. The book has 7 chapters and the focus on metals as enablers of human needs and wants is evident in each chapter. The first chapter presents the context of the work and data sources. The second chapter focuses on the origin and development of mining and metallurgy in pre-industrial Africa. Chapter 3 is dedicated to the interaction of nature and culture in the process of mining. Chapter 4 deals with the transformation of the ore into metal by smelting and the sociocultural aspects of this process. Chapter 5 explores the social and cultural roles acquired by metals as a result of fabrication into objects. Chapter 6 examines the social role of metals, trade in metals, cultural contact, proto-globalization, and technology transfer. Finally, Chapter 7 draws lessons for global anthropology from the African experience. The sources of information are adequately cited and the long list of references at the end of each chapter will be a boon to researchers in this field. The author highlights the cultural aspects and social context of the adoption of metallurgy in Africa while drawing parallels between practices in pre-industrial Africa and those in other parts of the world. The book is peppered with delightful vignettes that offer insights into the process of transforming nature into culturally significant objects. For instance, African miners, like their counterparts in Nepal and Latin America, called upon deities, spirits and ancestors to mediate between nature and humans. Women had distinct roles in this process, but there were variations in these roles and in the

    Both the developed and developing nations of the world would like to move toward a position of sustainable development while paying attention to the restoration of natural resources, improving the environment, and improving the quality of life. The impacts of geothermal development projects are generally positive. It is important, however, that the environmental issues associated with development be addressed in a systematic fashion. Drafted early in the project planning stage, a well-prepared Environmental Impact Assessment (EIA) can significantly add to the quality of the overall project. An EIA customarily ends with the decision to proceed with the project. The environmental analysis process could be more effective if regular monitoring, detailed in the EIA, continues during project implementation. Geothermal development EIAs should be analytic rather than encyclopedic, emphasizing the impacts most closely associated with energy sector development. Air quality, water resources and quality, geologic factors, and socioeconomic issues will invariably be the most important factors. The purpose of an EIA should not be to generate paperwork, but to enable superb response. The EIA should be intended to help public officials make decisions that are based on an understanding of environmental consequences and take proper actions. The EIA process has been defined in different ways throughout the world. In fact, it appears that no two countries have defined it in exactly the same way. Going hand in hand with the different approaches to the process is the wide variety of formats available. It is recommended that the world geothermal community work towards the adoption of a standard. The Latin American Energy Organization (OLADE) and the Inter-American Development Bank (IDB)(OLADE, 1993) prepared a guide that presents a comprehensive discussion of the environmental impacts and suggested mitigation alternatives associated with geothermal development projects.

    resource-based industries (e.g., agriculture). Naturaldisasters such as drought often dislocate large groups of people,amplifying their vulnerability to future disasters. Development itselfcan compound these vulnerabilities by promoting population growth,urbanization, intensive coastal development, and concentrations ofclimate-sensitive physical and health-related hazards. With its pool offinancial reserves, the global insurance market provides considerableadaptive capacity for weather-related damage to property, life, andhealth. The global insurance market--perhaps the world's largestindustry--represented $2.9 trillion in premiums in 2003, or approximatelyeight percent of global gross domestic product (GDP). To put this inperspective, the insurance industry s revenues make it equivalent to thethird largest country in the world in terms of GDP. In 2003, totalpremiums in emerging markets represented $314 billion (up from $270billion just a year earlier) or 11 percent of the global total, withgrowth rates often dramatically higher than those in the industrial world(twice as high, on average, between 1980 and 2000) and often exceedingGDP growth rates. Emerging markets are poised to represent half of worldinsurance premiums by the middle of this century.Insurance premiums arerising in part because the economic costs of natural disasters aregrowing, as is the insured share (up from a negligible level in the 1950sto approximately 20 percent of the total today).

The results also brought focus to the potential contributions that DOEs science and technology could make for solving the many difficult, multi-generational problems faced by hundreds of bi-national communities along the 2,000-mile shared border of the United States and Mexico. Efforts to address these U.S.-Mexico border issues were initially sponsored by the DOEs Albuquerque and Carlsbad offices. In subsequent years, the U.S. Congress directed appropriations to DOEs Carlsbad office to address public health, safety and security issues prevalent within U.S.-Mexico border communities. With ASLs assistance, DOEs Albuquerque office developed contacts and formed partnerships with interested U.S and Mexican government, academic, and commercial organizations. Border industries, industrial effluents, and public health conditions were evaluated and documented. Relevant technologies were then matched to environmental problem sets along the border. Several technologies that were identified and subsequently supported by this effort are now operational in a number of U.S.-Mexico border communities, several communities within Mexicos interior states, and in other parts of Latin America. As a result, some serious public health threats within these communities caused by exposure to toxic airborne pollutants have been reduced. During this time, DOEs Carlsbad office hosted a bilateral conference to establish a cross-border consensus on what should be done on the basis of these earlier investigative efforts. Participating border region stakeholders set an agenda for technical collaborations. This agenda was supported by several Members of Congress who provided appropriations and directed DOEs Carlsbad office to initiate technology demonstration projects. During the following two years, more than 12 private-sector and DOE-sponsored technologies were demonstrated in partnership with numerous border community stakeholders. All technologies were well received and their

    Latin Hypercube sampling (LHS) based design with a multidimensional kriging metamodel fit. For roughly the same number of simulations, the LHS-based metamodel yields a more robust predictive model, as verified by a k-fold cross-validation approach (with data split into training and test sets) as well by validation with an independent dataset. In the third category, a reduced-order modeling procedure is utilized that combines proper orthogonal decomposition (POD) for reducing problem dimensionality with trajectory-piecewise linearization (TPWL) in order to represent system response at new control settings from a limited number of training runs. Significant savings in computational time are observed with reasonable accuracy from the PODTPWL reduced-order model for both vertical and horizontal well problems – which could be important in the context of history matching, uncertainty quantification and optimization problems. The simplified physics and statistical learning based models are also validated using an uncertainty analysis framework. Reference cumulative distribution functions of key model outcomes (i.e., plume radius and reservoir pressure buildup) generated using a 97-run full-physics simulation are successfully validated against the CDF from 10,000 sample probabilistic simulations using the simplified models. The main contribution of this research project is the development and validation of a portfolio of simplified modeling approaches that will enable rapid feasibility and risk assessment for CO2 sequestration in deep saline formations.
