    2009-01-01

    The accumulated knowledge and the prospects for commercial energy production from fission breeder and fusion reactors are analyzed in this report. The publicly available data from past experimental breeder reactors indicate that a large number of unsolved technological problems exist and that the amount of "created" fissile material, either from the U238 --> Pu239 or from the Th232 --> U233 cycle, is still far below the breeder requirements and optimistic theoretical expectations. Thus huge e...

    2008-05-01

    Nuclear power technology has evolved through roughly three generations of system designs: a first generation of prototypes and first-of-a-kind units implemented during the period 1950 to 1970; a second generation of industrial power plants built from 1970 to the turn of the century, most of which are still in operation today; and a third generation of evolutionary advanced reactors which began being built by the turn of the 20^th century, usually called Generation III or III+, which incorporate technical lessons learned through more than 12,000 reactor-years of operation. The Generation IV International Forum (GIF) is a cooperative international endeavor to develop advanced nuclear energy systems in response to the social, environmental and economic requirements of the 21^st century. Six Generation IV systems under development by GIF promise to enhance the future contribution and benefits of nuclear energy. All Generation IV systems aim at performance improvement, new applications of nuclear energy, and/or more sustainable approaches to the management of nuclear materials. High-temperature systems offer the possibility of efficient process heat applications and eventually hydrogen production. Enhanced sustainability is achieved primarily through adoption of a closed fuel cycle with reprocessing and recycling of plutonium, uranium and minor actinides using fast reactors. This approach provides significant reduction in waste generation and uranium resource requirements.

  14. The generation IV nuclear reactor systems - Energy of future

    International Nuclear Information System (INIS)

    Ten nations joined within the Generation IV International Forum (GIF), agreeing on a framework for international cooperation in research. Their goal is to develop future-generation nuclear energy systems that can be licensed, constructed, and operated in an economically competitive way while addressing the issues of safety, proliferation, and other public perception concerns. The objective is for the Gen IV systems to be available for deployment by 2030. Using more than 100 nuclear experts from its 10 member nations, the GIF has developed a Gen IV Technology Roadmap to guide the research and development of the world's most advanced, efficient and safe nuclear power systems. The Gen IV Technology Roadmap calls for extensive research and development of six different potential future reactor systems. These include water-cooled, gas-cooled, liquid metal-cooled and nonclassical systems. One or more of these reactor systems will provide the best combination of safety, reliability, efficiency and proliferation resistance at a competitive cost. The main goals for the Gen IV Nuclear Energy Systems are: - Provide sustainable energy generation that meets clean air objectives and promotes long-term availability of systems and effective fuel use for worldwide energy production; - Minimize and manage their nuclear waste and noticeably reduce the long-term stewardship burden in the future, improving the protection of public health and the environment; - Increase the assurance that these reactors are very unattractive and the least desirable route for diversion or theft of weapons-usable materials, and provide increased protection against acts of terrorism; - Have a clear life-cycle cost advantage over other energy sources; - Have a level of financial risk comparable to other energy projects; - Excel in safety and reliability; - Have a low likelihood and degree of reactor core damage.

  15. Cardiac energy metabolism probed with nuclear magnetic resonance. Chapter 12

    International Nuclear Information System (INIS)

    Nuclear magnetic resonance (NMR) spectroscopy possesses great potential for studying myocardial energy metabolism. To ensure that the observed NMR signal predominantly originates from the heart, localization is required, which can be achieved by excision or exposure of the heart, or by means of sophisticated NMR localization techniques. A number of different atomic nuclei have been employed. H-1 NMR has been mainly used to follow lactate accumulation is ischemic or anoxic hearts. C-13 NMR has been applied to study the fate of different substrates in the citric acid cycle and amino acid pools, and the role of glycogen metabolism in ischemia or anoxia. F-19, Na-23 and K-39 have been employed to investigate the consequences of altered energy metabolism for myocardial intracellular concentrations of Ca2+, Na+ and K+. The most abundantly used nucleus for studying myocardial energy metabolism is P-31. Numerous contributions have been made to the investigation of ischemia and reperfusion, protection of the heart against the consequences of ischemia and reperfusion, contractile failure, variation of high-energy phosphate levels over the cardiac cycle, regulation of oxidative phosphorylation and intracellular enzyme kinetics of both isolated perfused hearts and hearts in situ. Even human myocardial metabolism can be assessed by P-31 NMR, which is on the verge of becoming a clinical tool for investigating heart disease. 106 refs.; 3 figs.; 1 table

  18. External energy policy: Old fears and new dilemmas in a larger Union. Chapter 9

    International Nuclear Information System (INIS)

    This chapter attempts both to analyse the development of energy policy making in the EU and to discuss the energy security dilemmas that confront the member states in the short and medium term. The central issue here is how security of supply and a sustainable energy system can be achieved in a market environment, which is the main thrust of the Commissions proposals, while at the same time government intervention in international energy markets is on the rise. It is suggested that the mismatch between the level of government involvement and the market model in the international energy sector has become more pronounced lately and impacts upon the security of supply and demand policy toolset of consumer and producer countries. Arguably, the switch from an international oil and gas buyers' market to a sellers market has not only rekindled resource nationalism in producer countries but also stimulated a certain preference for bilateral energy relations over multilateral ones in some consumer countries in an attempt to secure supplies. Chinese energy diplomacy in Africa and elsewhere is a good example of bilateralism, while some member states also deem the Nordstream pipeline project to be an example of energy bilateralism on the part of Germany. The latter project was clearly a trigger for the current EU proposal on external energy relations, encouraging member states to 'speak with one voice'. However, it will be argued in this chapter that the asymmetry in import dependency among the member states, the preference of member states for a certain energy mix, the member state' competitive position in world markets and different foreign and security approaches, will make 'speaking with one voice' a lot harder to achieve than in climate change matters. This chapter first gives some facts and figures about European energy. It then discusses both past and current energy policy in the EU. The issue is raised whether the strategic energy interests of the member states are

  20. Energy prospects for the sector Transportation. Scenario IV

    International Nuclear Information System (INIS)

    In this study for the Swiss Federal Office of Energy, mathematical models are used to predict the energy consumption by the year 2030 of the whole transportation sector including air traffic for Switzerland. In the so-called Scenario IV considered here, stringent but still realistic assumptions are made regarding technologies, taxes and legislation while economic growth is retained as an essential background feature as in previous scenarios with less stringent measures. Fossil fuels still are the main energy source for road and air transportation, but drastic efficiency improvements reduce the specific fuel consumption: (i) with an average reduction of 3% a year, the specific consumption of cars falls from 9 litre/100 km in 1990 down to less than 3 litre/100 km in 2030; (ii) for lorries, it falls from 30 down to 22 litre/100 km in the same time period; (iii) the energy efficiency improvement up to 2030 is 45% for the air traffic, under the assumption of an internationally harmonised kerosene tax. In parallel, fuel market price increase, so that the energy expenses remain constant for most vehicles. For goods transportation by rail an efficiency improvement of 33% is assumed, so that a partial shift from the road to the rail takes place. For passengers transportation by rail, better comfort, more frequent trains and extended regional tariff agreements stimulate an increased usage of public transportation systems. Measures are also considered in the fields of urbanism (where to live and where to work) and traffic management (avoidance of empty courses for lorries). Altogether, the measures described lead to an annual final-energy consumption of 148 PJ in 2030 for Switzerland, compared to 251 PJ in 1990

  1. Regulation and policy initiatives for sustainable energy in sub-Saharan Africa. Chapter 1

    International Nuclear Information System (INIS)

    Environmental change and sustainable development present a challenge for all nations. Developed countries have to dismantle and change historic practice before progressing, whereas developing countries can move directly to new technology and new institutional frameworks. This chapter seeks to identify trends in energy supply and use that both improve sustainability and provide opportunities for commerce and industry. Worldwide experience is studied for application in sub-Saharan Africa (abbreviated as 'Africa' henceforward). Such application is central to UNIDO's programmes in energy and environment. These programmes consider both the supply and the demand sides, by the provision of energy for industry, use of renewable energy resources and improved industrial energy end-use efficiency. Key factors are de-linking intensity of energy use from economic growth and reducing environmental damage from energy supply and use The background for this chapter is 'Sustainable Energy Regulation and Policy-making for Africa', a set of 20 training-modules produced for UNIDO and REEEP (the Renewable Energy and Energy Efficiency Partnership). The modules will be used by governments, regulatory offices and industry in Africa for stimulating policy and commercial development in renewable energy and energy efficiency. Of particular relevance is the general trend to more liberalized electricity supplies, as regulated within new legislation. Within each country, institutional frameworks can be changed and improved for the benefit of both citizens and commerce alike. There is a common trend worldwide to include institutional mechanisms for the increase of renewable energy generation and the efficient use of energy within regulatory legislation, e.g. (Harrington et al., 2007). Government involvement and ministerial regulation is most common for electricity. In all countries, the introductory stages of electricity supply have been strongly influenced by national and local government action

    Nuclear fission energy is considered to be somewhere between the holy grail, required to solve all energy worries of the human industrialized civilization, and a fast path directly to hell. Discussions about future energy sources and the possible contribution from nuclear energy are often dominated by variations of fundamentalists and often irrational approaches. As a result, very little is known by the general public and even by decision makers about the contribution of nuclear energy today,...

    The Hawaii Energy Strategy (HES) Program is a seven-project effort led by the State of Hawaii Department of Business, Economic Development & Tourism (DBEDT) to investigate a wide spectrum of Hawaii energy issues. The East-West Center`s Program on Resources: Energy and Minerals, has been assigned HES Project 2, Fossil Energy Review, which focuses on fossil energy use in Hawaii and the greater regional and global markets. HES Project 2 has four parts: Task I (World and Regional Fossil Energy Dynamics) covers petroleum, natural gas, and coal in global and regional contexts, along with a discussion of energy and the environment. Task II (Fossil Energy in Hawaii) focuses more closely on fossil energy use in Hawaii: current utilization and trends, the structure of imports, possible future sources of supply, fuel substitutability, and energy security. Task III`s emphasis is Greenfield Options; that is, fossil energy sources not yet used in Hawaii. This task is divided into two sections: first, an in-depth {open_quotes}Assessment of Coal Technology Options and Implications for the State of Hawaii,{close_quotes} along with a spreadsheet analysis model, which was subcontracted to the Environmental Assessment and Information Sciences Division of Argonne National Laboratory; and second, a chapter on liquefied natural gas (LNG) in the Asia-Pacific market and the issues surrounding possible introduction of LNG into the Hawaii market.

  8. Fast breeder reactors in relation to energy requirements. Chapter 2.2

    International Nuclear Information System (INIS)

    It is shown that the world is going to need substantial quantities of energy from new sources early in the next century. Although it may be possible to get a significant amount from solar and geothermal sources, it is far too early to predict how large a contribution they will be able to make. Nuclear power can make a large contribution and it would be wrong to do anything to close this option at this stage. Although there is considerable uncertainty about the precise quantity of commercially exploitable uranium in the world, it is almost certain that breeder reactors will be required. The time-scale is such that utilities throughout the world will need to be able to order breeders in quantity with complete confidence for operation from the mid 1990s onwards. The engineering, safety and logistic problems that are considered in the other chapters of this book are such that, if we are to meet this time-scale, we must press ahead with the utmost urgency.

    1980-10-01

    Solar energy has become a major alternative for supplying a substantial fraction of the nation's future energy needs. The Department of Energy (DOE) supports activities ranging from the demonstration of existing technology to research on future possibilities; and at LBL projects are in progress which span that range of activities. To assess various solar applications it is important to quantify the solar resource. In one project, LBL is cooperating with the Pacific Gas and Electric Company in the implementation and operation of a solar radiation data collection network in northern California. Special instruments have been developed and are now in use to measure the solar and circumsolar (around the sun) radiation. These measurements serve to predict the performance of solar designs which use focusing collectors (mirrors or lenses) to concentrate the sunlight. Efforts are being made to assist DOE in demonstrating existing solar technology. DOE's San Francisco Operations Office (SAN) has been given technical support for its management of commercial-building solar demonstration projects. The installation of a solar hot water and space heating system on an LBL building established model techniques and procedures as part of the DOE Facilities Solar Demonstration Program. Technical support is also provided for SAN in a DOE small scale technology pilot program in which grants are awarded to individuals and organizations to develop and demonstrate solar technologies appropriate to small scale use. In the near future it is expected that research will exert a substantial impact in the areas of solar heating and cooling. An absorption air conditioner is being developed that is air cooled yet suitable for use with temperatures available from flat plate collectors. With inexpensive but sophisticated micro-electronics to control their operation, the performance of many-component solar heating and cooling systems may be improved, and work is under way to develop such a

    Solar energy has become a major alternative for supplying a substantial fraction of the nation's future energy needs. The U.S. Department of Energy (DOE) supports activities ranging from the demonstration of existing technology to research on future possibilities. At Lawrence Berkeley Laboratory (LBL), projects are in progress that span a wide range of activities, with the emphasis on research to extend the scientific basis for solar energy applications, and on preliminary development of new approaches to solar energy conversion. To assess various solar applications, it is important to quantify the solar resource. Special instruments have been developed and are now in use to measure both direct solar radiation and circum-solar radiation, i.e., the radiation from near the sun resulting from the scattering of sunlight by small particles in the atmosphere. These measurements serve to predict the performance of solar designs that use focusing collectors employing mirrors or lenses to concentrate the sunlight. Efforts have continued at a low level to assist DOE in demonstrating existing solar technology by providing the San Francisco Operations Office (SAN) with technical support for its management of commercial-building solar demonstration projects. Also, a hot water and space-heating system has been installed on an LBL building as part of the DOE facilities Solar Demonstration Program. LBL continues to provide support for the DOE Appropriate Energy Technology grants program. Evaluations are made of the program's effectiveness by, for example, estimating the resulting potential energy savings. LBL also documents innovative features and improvements in economic feasibility as compared to existing conventional systems or applications. In the near future, we expect that LBL research will have a substantial impact in the areas of solar heating and cooling. Conventional and new types of high-performance absorption air conditioners are being developed that are air

    The U.S. nuclear safety assistance activities have had a direct and substantial impact on improving safe operations of 67 Soviet-designed commercial nuclear power plants in Armenia, Bulgaria, Czech Republic, Hungary, Kazakhstan, Lithuania, Russia, Slovakia, and Ukraine. The U.S. Department of Energy worked with these host countries both to improve safe nuclear operations and in some cases assist in plant shutdown. Independent international safety reviews have identified significant progress in the Eastern European countries to improve the safety of their nuclear power plants since the early 1990s. In addition, all of the probabilistic risk assessments conducted at these plants show a major reduction in the frequency of core damage accidents since U.S. assistance to improve safety at these reactors began. Improved operational safety follows from the combined efforts to improve operator performance. These efforts include providing simulators for operators to practice handling emergency scenarios, developing emergency operating instructions that guide operators calmly through emergencies, providing safety parameter display systems that give operators immediate graphical information on the status of plant systems and training the operators on the safety basis for the plants they operate

    As reflected in the U.S. ''National Energy Policy'', nuclear energy has a strong role to play in satisfying our nation's future energy security and environmental quality needs. The desirable environmental, economic, and sustainability attributes of nuclear energy give it a cornerstone position, not only in the U.S. energy portfolio, but also in the world's future energy portfolio. Accordingly, on September 20, 2002, U.S. Energy Secretary Spencer Abraham announced that, ''The United States and nine other countries have agreed to develop six Generation IV nuclear energy concepts''. The Secretary also noted that the systems are expected to ''represent significant advances in economics, safety, reliability, proliferation resistance, and waste minimization''. The six systems and their broad, worldwide research and development (R&D) needs are described in ''A Technology Roadmap for Generation IV Nuclear Energy Systems'' (hereafter referred to as the Generation IV Roadmap). The first 10 years of required U.S. R&D contributions to achieve the goals described in the Generation IV Roadmap are outlined in this Program Plan.

    International Nuclear Information System (INIS)

    This comprehensive report published by the Swiss Federal Office of Energy (SFOE) takes a look at the four scenarios concerning future developments in Swiss energy supply policy. The four complex scenarios include variants entitled 'business as usual', 'increased co-operation', 'new priorities' and 'on the way to a 2000-Watt society'. These scenarios deal with the development of energy demand and electricity offerings in Switzerland for the period 1990 to 2035. They are reviewed in the light of various sensitivity factors. These sensitivity factors include a high GDP, oil prices of 50 US-dollars per barrel and a warmer climate. The report presents the results of the model calculations made. First of all, the report takes a look at the motivation and aims behind the work and discusses the modelling methods, system limits and conventions used and the possibilities offered by the perspectives as well as the limits encountered. The four scenarios are then presented and discussed in detail. Implementation variants in the private, services, industrial and traffic sectors are discussed and various electricity supply variants are presented, as are the associated environmental issues involved. The scenarios are compared with each other and pricing and security of supply issues are discussed. Finally, a short synopsis of the scenarios is presented and decision criteria are discussed as are implementation instruments. Ethical dilemmas and the risks involved are noted

  20. Energy spectra of delayed neutrons from separated fission products. IV

    International Nuclear Information System (INIS)

    Energy spectra of delayed neutrons from the mass-separated fission products 8890Br, 138140I, 142(Xe,Cs) and 144Cs have been measured. Average level spacings, neutron envelopes and Psub(n) values were calculated and compared with the experimental data. The neutron envelopes are well reproduced for all precursors except 90Br and 140I. For the latter the neutron window predicted by various mass formulae is too wide and a considerable reduction was found necessary to bring calculated envelopes in agreement with the experimental distributions.

  1. Energy levels, oscillator strengths and lifetimes in Cl IV

    International Nuclear Information System (INIS)

    Full text: Emission lines due to allowed and intercombination transitions in multiply charged Si-like ions are observed in solar corona and laser produced plasma. The lines arisen from intercombination transitions have been shown to be very useful, for instance, in understanding density fluctuations and elementary processes which occur in both interstellar and laboratory plasma and the determination of transition energies, oscillator strengths and transition probabilities of these lines as needed for a qualitative analysis of the spectra are not well known. This is mainly because these weak lines are usually sensitive to the theoretical modeling and have been a challenge for the atomic structure theory. We have calculated the excitation energies, oscillator strengths and transition probabilities for electric-dipole-allowed and intercombination transitions among the fine-structure levels of the terms belonging to the configurations (1s22s22p6)3s23p2, 3s3p3, 3s23p3d, 3p4, 3s23p4s, 3s23p4p, 3s3p2(2S)4s, 3s3p2(2P)4s, 3s3p2(4P)4s, 3s3p2(2D)4s, 3s23p4d and 3s23p4f of Si-like chlorine, using extensive configuration-interaction (CI) wavefunctions. The relativistic effects in intermediate coupling are incorporated by means of the Breit-Pauli Hamiltonian. Small adjustments to the diagonal elements of the Hamiltonian matrices have been made so that the energy splittings are as close as possible to the experiment. From our radiative rates, we have also calculated the radiative lifetimes of the levels. In this calculation we have investigated the effects of electron correlations on our calculated data, particularly on the intercombination transitions, by including orbitals with up to n=5 quantum number. We considered up to two electron excitations from the valence electrons of the basic configurations and included a large number of configurations. These configurations represent all major internal, semi-internal and all-external electron correlation effects. The mixing among

    Annex IV is an international collaborative project to examine the environmental effects of marine energy devices among countries through the International Energy Agency’s Ocean Energy Systems Initiative (OES). The U.S. Department of Energy (DOE) serves as the Operating Agent for the Annex, in partnership with the Bureau of Ocean Energy Management (BOEM; formerly the Minerals Management Service), the Federal Energy Regulatory Commission (FERC), and National Oceanographic and Atmospheric Administration (NOAA). Numerous ocean energy technologies and devices are being developed around the world, and the few data that exist about the environmental effects of these technologies are dispersed among countries and developers. The purpose of Annex IV is to facilitate efficient government oversight of the development of ocean energy systems by compiling and disseminating information about the potential environmental effects of marine energy technologies and to identify methods of monitoring for these effects. Beginning in 2010, this three-year effort produced a publicly available searchable online database of environmental effects information (Tethys). It houses scientific literature pertaining to the environmental effects of marine energy systems, as well as metadata on international ocean energy projects and research studies. Two experts’ workshops were held in Dublin, Ireland (September 2010 and October 2012) to engage with international researchers, developers, and regulators on the scope and outcomes of the Annex IV project. Metadata and information stored in the Tethys database and feedback obtained from the two experts’ workshops were used as resources in the development of this report. This Annex IV final report contains three case studies of specific interactions of marine energy devices with the marine environment that survey, compile, and analyze the best available information in one coherent location. These case studies address 1) the physical interactions

    need for substantial research. As we consider I and C systems in Generation IV reactors, we have the opportunity to take a much less 'timid' design philosophy than was taken in the design of I and C systems in the ALWRs. We need to make use of advanced technology to design an I and C system for the Generation IV multi-unit plant designs currently being considered. Such a design should accomplish the following: 1. provides for multi-unit control; 2. contributes to a plant design objective of a very low core damage frequency; 3. maximizes plant thermal efficiency (>50%); 4. maximizes plant capacity factor (>90%); 5. optimizes operability; 6. maximizes maintainability; 7. provides for on-line monitoring, calibration, and diagnostics; 8. provides optimum response to disturbances; 9. provides excellent load-following capability. When we consider the current situation in operating Generation I and II nuclear power plants and even Generation III ALWR design, we conclude that Generation IV reactors should employ at least Generation II measurement systems. Let us first consider data transmission, which is a form of communication, and ask the question: Do new communication-transferring methods by electrons flow in copper wires? The obvious answer is no. Virtually all new communication systems are using some electromagnetic method, such as light, microwaves, HF or VHF radio signals, and virtually no copper wires. When we envision Generation IV nuclear power plants, we should minimize the use of copper wires for data transmission. We should transmit data primarily by fiber optics and various wireless methods, some of which can penetrate thick barriers. Now let us consider sensors. If we use light for data transmission, then we should also use optical-based sensors. We should also take advantage of microprocessors, which provide opportunities to embed 'intelligence' in the sensor that can be used to increase accuracy, stability, and tolerance to external stressors (i.e., radiation

    Construction of ISS will require more than 1000 hours of EVA. Outside of ISS during EVA, astronauts and cosmonauts are likely to be exposed to a large fluence of electrons and protons. Development of radiation protection guidelines requires the determination of the minimum energy of electrons and protons that penetrate the suits at various locations. Measurements of the water-equivalent thickness of both US. and Russian EVA suits were obtained by performing CT scans. Specific regions of interest of the suits were further evaluated using a differential range shift technique. This technique involved measuring thickness ionization curves for 6-MeV electron and 155-MeV proton beams with ionization chambers using a constant source-to-detector distance. The thicknesses were obtained by stacking polystyrene slabs immediately upstream of the detector. The thicknesses of the 50% ionizations relative to the maximum ionizations were determined. The detectors were then placed within the suit and the stack thickness adjusted until the 50% ionization was reestablished. The difference in thickness between the 50% thicknesses was then used with standard range-energy tables to determine the threshold energy for penetration. This report provides a detailed description of the experimental arrangement and results.

    Over the last 5 years the growth rate in wind energy has been as high as 30% an on average nearly 25% in all continents, and a considerable number of countries have very ambitious goals concerning their wind energy development, therefore it could be likely to cover as much as 20% of the world's electricity consumption by wind in 2030 and 35% in 2050, although on the shorter term growth is expected to take place mainly in Europe, USA and China. The market is maturing, therefore achieving more stable economies in the wind energy sector. As a result, better electrical grids suited for wind power are being developed and better planning tools as well as other frameworks, which benefit the market for installation of wind turbines, are being implemented across all wind energy countries. The cost of wind-generated electricity has fallen steadily for the last two decades, driven largely by technological advances, increased production levels and the use of larger turbines. Between 1985 and 2005, production costs energy from of wind turbines decreased by nearly 100% in 2006 prices. The price rises seen in last three years due to capacity problems in the industry are expected to stop, once supply system constraints are overcome. Onshore wind is considered commercial at sites with good wind resources and grid access. Cost reductions in both turbines and infrastructure are expected to bring investment costs to 0.88 mill. Euro/MW in 2030 and 0.8 mill. Euro/MW in 2050. On the other hand, offshore wind is in pre-commercial development phase. Considerable costs improvements are expected in all areas making costs go down to 1. 4 mill. Euro/MW in 2030 and 1.3 mill. Euro/MW in 2050. Priority RD and D areas to foster continued growth in wind power are to increase the value and reduce uncertainties. This will mean further cost reductions on longer terms, enabling large-scale use by improved grid integration and storage facilities and minimizing environmental impact. (au)

    In order to control pollutants resulting from energy production and utilization, adequate methods are required for monitoring the level of various substances often present at low concentrations. The Energy and Environment Division Applied Research in Laser Spectroscopy & Analytical Techniques Program is directed toward meeting these needs, Emphasis is on the development of physical methods, as opposed to conventional chemical analysis techniques. The advantages, now widely recognized, include ultra-high sensitivity coupled with minimal sample preparation. In some instances physical methods provide multi-parameter measurements which often provide the only means of achiev·ing the sensitivity necessary for the detection of trace contaminants.

    International Nuclear Information System (INIS)

    A general discussion is given of the use of neutron reaction data in the nuclear energy programme and of the importance of accurate fission cross-section data. A brief summary of the neutron physics of nuclear reactors is followed by a survey of the types of fuel cycle and the fission cross-sections which are of principal interest. The use of nuclear data in reactor calculations is examined and typical target accuracy requirements for the prediction of reactor properties are summarised. Simple arguments are given to show how the accuracy of prediction of some important reactor properties depends on the accuracy of the nuclear data. The use of integral measurements to supplement energy dependent cross-section data is reviewed and a procedure outlined which has been developed for defining a combined programme of integral data and differential cross-section measurements which could meet the chosen target accuracies for a set of reactor parameters. Finally typical fission cross-section accuracy requirements are presented. (U.K.)

    Global trends toward developing new energy resources from lower grade, larger tonnage deposits that are not generally accessible using “conventional” extraction methods involve variations of subsurface in situ extraction techniques including in situ oil-shale retorting, hydraulic fracturing of petroleum reservoirs, and in situ recovery (ISR) of uranium. Although these methods are economically feasible and perhaps result in a smaller above-ground land-use footprint, there remain uncertainties regarding potential subsurface impacts to groundwater. This chapter provides an overview of the role of water in these technologies and the opportunities and challenges for water reuse and recycling.

    We report calculations of energy levels and radiative rates ($A$-values) for transitions in Cr-like Co IV and Ni V. The quasi-relativistic Hartree-Fock (QRHF) code is adopted for calculating the data although GRASP (general-purpose relativistic atomic structure package) and flexible atomic code (FAC) have also been employed for comparison purposes. No radiative rates are available in the literature to compare with our results, but our calculated energies are in close agreement with those compiled by NIST for a majority of the levels. However, there are discrepancies for a few levels of up to 3\\%. The $A$-values are listed for all significantly contributing E1, E2 and M1 transitions, and the corresponding lifetimes reported, although unfortunately no previous theoretical or experimental results exist to compare with our data.

    In the past, energy system planning was largely restricted to national boundaries. Energy trade with neighbouring countries was often regarded as a last resort. Focusing planning exclusively within national boundaries, however, ignores many synergies that can be exploited if countries were to adopt a regional approach to energy planning. Constraining factors, such as sub-critical grid and market capacities, large unit plant sizes, large distances between demand and supply centers, limited institutional infrastructure and technical know-how, and workforce requirements, could be alleviated by joint infrastructure and resource development and sharing. Furthermore, many issues of sustainable energy development such as energy security and reliability, environmental protection and economic viability may be better advanced in a regional context. A good example of a regional approach is the West African Gas Pipeline Project, which in its first stage will make Nigerian gas resources accessible to Benin, Togo and Ghana. Another example is the Southern African Power Pool - an association of 14 national utilities in the southern African region. Information and best practice sharing in the field of biofuel production or utilizing economies of scale or create better negotiating possibilities with suppliers are further benefits of regionalization that may help bring down costs and thus improve the accessibility and affordability of energy services. In short, infrastructure sharing by two or more countries could reduce economic and financial constraints and associated financial risks, improve load factors for capital intensive infrastructures, and make it easier to meet national or international environmental targets. Regional energy planning does not obviate national energy planning - the latter is an inevitable first step - it just takes it one step further. For example, in the three Baltic countries of Estonia, Latvia and Lithuania, the IAEA analysis tools were first applied to

    Gas-cooled fast reactor (GFR) designs are being developed to meet Gen IV goals of sustainability, economics, safety and reliability, and proliferation resistance and physical protection as part of an International Generation IV Nuclear Energy System Research Initiative effort. Different organizations are involved in the development of a variety of GFR design concepts. The current analysis has focused on the evaluation of low-pressure drop, pin-core designs with favorable passive cooling properties. Initial evaluation of the passive cooling safety case for the GFR during depressurized decay heat removal accidents with concurrent loss of electric power have resulted in requirements for a reduction of core power density to the 100 w/cc level and a low core pressure drop of 0.5 bars. Additional design constraints and the implementation of their constraints are evaluated in this study to enhance and passive cooling properties of the reactor. Passive cooling is made easier by a flat radial distribution of the decay heat. One goal of this study was to evaluate the radial power distribution and determine to what extent it can be flattened, since the decay heat is nearly proportional to the fission power at shutdown. In line with this investigation of the radial power profile, an assessment was also made of the control rod configuration. The layout provided a large number of control rod locations with a fixed area provided for control rods. The number of control rods was consistent with other fast reactor designs. The adequacy of the available control rod locations was evaluated. Future studies will be needed to optimize the control rod designs and evaluate the shutdown system. The case for low pressure drop core can be improved by the minimization of pressure drop sources such as the number of required fuel spacers in the subassembly design and by the details of the fuel pin design. The fuel pin design is determined by a number of neutronic, thermal-hydraulic (gas dynamics

    The electric utility companies worldwide suffer, in greater or lesser degree, electrical energy losses. A great percentage of these losses is mostly due to illegal appropriations of energy. The consumers, by means of illicit practices such as clandestine connections and alteration of the operation of electricity meters, carry out the energy robbery. In order to try to alleviate the problematic of electric energy losses, in their majority by illicit, the electric utility companies have implemented one or more actions. Among the most important are: Visual inspection of the metering facilities. Its purpose is to verify the condition of the traditional protections of the metering installations, such as the seals and safety rings. Detection Equipment: These are recorders of energy consumption and of faults in conductors and are used to detect illicit connections and deviations in the consumption patterns and to the electrical energy connection or to the secondary distribution network. Statistical analysis of consumption: Many electric facility companies have adapted their processing consumption reading systems to detect deviations in the of consumption patterns of their clients. This could correspond to abnormal situations. Since this country is not extraneous to the problematic of energy losses, in the Instituto de Investigaciones Electricas it was developed a System of Measurement and Detection of Losses of Electrical Energy (SIM-IV) as a result of the knowledge of the problematic obtained from the projects in the metering area and of the interaction through work meetings with personnel of the Comision Federal de Electricidad and of Luz y Fuerza del Centro (LyFC), in which concepts of advanced technology were applied for the measurement of electrical variables. The SIM-IV is a system oriented to the metering of consumption and the detection of robberies of electrical energy caused by clandestine connections and non-allowed interventions to the energy meters.

    The BigBOSS experiment is a proposed DOE-NSF Stage IV ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and the growth of structure with an all-sky galaxy redshift survey. The project is designed to unlock the mystery of dark energy using existing ground-based facilities operated by NOAO. A new 4000-fiber R=5000 spectrograph covering a 3-degree diameter field will measure BAO and redshift space distortions in the distribution of galaxies and hydrogen gas spanning redshifts from 0.2Energy Task Force figure of merit (DETF FoM) for this experiment is expected to be equal to that of a JDEM mission for BAO with the lower risk and cost typical of a ground-based experiment. This project will enable an unprecedented multi-object spectroscopic capability for the U.S. community through an existing NOAO facility. The U.S. community would have access directly to this instrument/telescope combination, as well as access to the legacy archives that will be created by the ...

  9. Overview of the CEA R and D support to generation IV nuclear energy systems

    International Nuclear Information System (INIS)

    As a result of an early technology road-map performed at the end of 2000, the CEA selected a sequenced development of advanced gas cooled high temperature nuclear systems as main focus for its R and D programme on future nuclear energy systems. The selection of this research objectives originates both from the significance of fast neutrons and high temperature for nuclear energy to meet the needs anticipated beyond 2020/2030, and from the significant common R and D pathway that supports both medium term industrial projects and more advanced versions of gas cooled reactors. The first step of the 'Gas Technology Path' aims to support the development of a modular HTR likely to meet international market needs around 2020. The second step is a Very High Temperature Reactor (> 950 deg. C) to efficiently produce, among others, hydrogen though thermo-chemical water splitting or to generate electricity with an efficiency above 50%. The third step of the Path is a Gas Fast Reactor that features a fast-spectrum helium-cooled reactor and closed fuel cycle, with a direct-cycle helium turbine for electricity production and full recycle of actinides. The paper succinctly presents the R and D program launched in 2001 by the CEA with industrial partners on the 'Gas Technology Path', which is destined to become the contribution of France to the development of the VHTR and the GFR within the next phase of the Generation IV Forum

    Energy Technology Data Exchange (ETDEWEB)

    1978-03-01

    Many Indian tribes own rich deposits of very valuable energy resources. Existing and proposed uses of these tribal resources range from limited development of small oil and gas fields to large-scale extraction and conversion of coal, uranium, and oil shale. The adverse environmental impacts of such projects may create a conflict between a tribe's environmental policies and its economic, employment, and other long-term goals. The purpose of this volume is to provide tribal decision makers with reference documents on the mechanisms that are available to resolve such conflicts. This report focuses on the role of existing environmental laws in enabling tribes to achieve the needed balance among its objectives. Over a dozen major Federal statutes have been enacted to achieve this purpose. One law, the National Environmental Policy Act (NEPA), provides procedures to ensure that environmental factors are included in the Federal decision-making process. Numerous other laws, such as the Clean Air Act, have been enacted to prevent or control any negative environmental impacts of actual projects. This volume documents the key provisions of the laws and regulations, and discusses their effectiveness in meeting total needs. Also, tribal options to strengthen these mechanisms are highlighted. Sections II and III report on the role of NEPA in tribal development decisions. Section IV reviews those laws and regulations that control project operations.

    This Technology Road-map Update provides an assessment of progress made by the Generation IV International Forum (GIF) in the development of the six systems selected when the original Technology Road-map was published in 2002. More importantly, it provides an overview of the major R and D objectives and milestones for the coming decade, aiming to achieve the Generation IV goals of sustainability, safety and reliability, economic competitiveness, proliferation resistance and physical protection. Lessons learnt from the Fukushima Daiichi nuclear power plant accident are taken into account to ensure that Generation IV systems attain the highest levels of safety, with the development of specific safety design criteria that are applicable across the six systems. Accomplishing the ten-year R and D objectives set out in this new Road-map should allow the more advanced Generation IV systems to move towards the demonstration phase. (authors)

  13. Chapter 10: CPV Multijunction Solar Cell Characterization

    Energy Technology Data Exchange (ETDEWEB)

    Osterwald, Carl R.; Siefer, Gerald

    2016-04-15

    Characterization of solar cells can be divided into two types: the first is measurement of electrooptical semiconductor device parameters, and the second is determination of electrical conversion efficiency. This chapter reviews the multijunction concepts that are necessary for understanding Concentrator photovoltaic (CPV) cell characterization techniques, and describes how CPV efficiency is defined and used. For any I-V measurement of a multijunction cell, the sun simulator spectrum has to be adjusted in a way that all junctions generate the same photocurrent ratios with respect to each other as under reference conditions. The chapter discusses several procedures for spectral irradiance adjustments of solar simulators, essential for multijunction measurements. It overviews the light sources and optics commonly used in simulators for CPV cells under concentration. Finally, the chapter talks about the cell area, quantum efficiency (QE), and current-voltage (I-V) curve measurements that are needed to characterize cells as a function of irradiance.

    Energy levels, lifetimes, and transition probabilities for transitions between computed levels of 3d^5 of Fe IV are reported. The E2 and M1 transition probabilities are compared with earlier theoretical results, often only the values published by Garstang in 1958. From the available astronomical observations of optical emission lines arising from the same level, a few direct tests are now possible and they show consistency with the theoretical calculations.

  17. ENDF/B-IV representation of the 238U total neutron cross section in the resolved resonance energy region

    International Nuclear Information System (INIS)

    The ENDF/B-IV prescription fails to represent correctly the 238U total (and scattering) cross section between the levels of the resolved range. It is shown how this representation can be improved by properly accounting for the contribution of levels outside the resolved region to the cross section at energies inside the resolved region, and by substituting the more precise multilevel Breit-Wigner formula for the presently used single-level formula. The importance of computing accurately the minima in the total cross section is illustrated by comparing values of the self-shielded capture resonance integral computed with ENDF/B-IV and with a more accurate cross section model

    2014-09-01

    This chapter focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification (EM&V) studies for energy efficiency (EE) programs. The chapter provides a definition of net savings, which remains an unsettled topic both within the EE evaluation community and across the broader public policy evaluation community, particularly in the context of attribution of savings to particular program. The chapter differs from the measure-specific Uniform Methods Project (UMP) chapters in both its approach and work product. Unlike other UMP resources that provide recommended protocols for determining gross energy savings, this chapter describes and compares the current industry practices for determining net energy savings, but does not prescribe particular methods.

  19. Introduction to the Revision 5 of evaluation methodology for proliferation resistance and physical protection of Generation IV nuclear energy systems

    International Nuclear Information System (INIS)

    The Generation IV (GEN IV) International Forum (GIF) Proliferation Resistance and Physical Protection Working Group (PRPP WG) was established in December, 2002, as one of the crosscut groups under GIF, in order to develop a methodology for evaluating Proliferation Resistance and Physical Protection of potential GEN IV options. The group currently consists of the experts from the U.S. national laboratories and universities, from Canada, France, Republic of Korea (ROK), Japan, the International Atomic Energy Agency (IAEA), and European Union(EU). Revision 5 of the 'Evaluation Methodology for Proliferation Resistance and Physical Protection of Generation IV Nuclear Energy Systems' is also known as the Rev. 5 report. The Rev. 5 report provides an important evaluation framework that was developed with consensus-based discussions, and published by the OECD-NEA in November, 2006. The activities of PRPP WG has contributed to establish PR and PP culture, in addition, they have affected the discussion on the proliferation resistance of the future nuclear fuel cycle. Japan has to develop the future nuclear cycle system with sufficient proliferation resistance and physical protection features and demonstrate and explain about its effective NESs to the domestic and international society. For these reasons, and recognizing the usefulness of the Revision-5 Report, it was translated and published here as a Japanese-language edition with the concurrence of the OECD-NEA. The original report in English language can be downloaded at the OECD-NEA website. The translation sticks as closely as possible to the original, and that of technical terms were carefully done. If a term cannot be translated appropriately into Japanese, the original English wording is also Put down. Safeguards terms were translated with reference to 'IAEA Safeguards Glossary 2001 Edition' (Japanese), Published by the Nuclear Material Control Center Japan (NMCC).

    The Generation IV International Forum (GIF) is carrying out research and development for several Generation IV systems with the aim of meeting goals in the areas of sustainability, safety and reliability (S and R), proliferation resistance and physical protection (PR and PP), and economics. It has formed three working groups to help define design guidelines and to develop methodologies to assess progress in meeting the S and R, PR and PP and economics goals: the Risk and Safety Working Group, the PR and PP Working Group, and the Economics Modeling Working Group. Their methodologies [1,2] are at different stages of development, testing, and application for system development and assessment. The optimization of a nuclear energy system's performance requires an integrated consideration of all the goal areas and careful evaluation of tradeoffs for different system design and operating parameters. Design approaches motivated by each of the goal areas (in isolation of the other goal areas) may be mutually compatible or in conflict. However no systematic methodology approach has yet been developed to identify and maximize synergies and optimally balance conflicts across the possible design configurations and operating modes of a nuclear energy system. Because most Generation IV systems are at an early stage of development, design, and assessment, GIF is only beginning to identify synergies and conflicts between PR and PP, S and R, and economics goals. The coupling between PR and PP and R and S goals is perhaps most apparent. For example, passive systems and structures tend to be synergistic for both safety and security, if designed for both functions. Likewise, it is important to know where nuclear materials are and how their protection against hazards and threats is organized from both PR and PP and S and R standpoints. Human performance programs can also be designed to be synergistic for both areas. In emergency response there are clear areas of potential conflict

  2. Creep Behavior of High Temperature Alloys for Generation IV Nuclear Energy Systems

    Science.gov (United States)

    Wen, Xingshuo

    The Very High Temperature Reactor (VHTR) is one of the leading concepts of the Generation IV nuclear reactor development, which is the core component of Next Generation Nuclear Plant (NGNP). The major challenge in the research and development of NGNP is the performance and reliability of structure materials at high temperature. Alloy 617, with an exceptional combination of high temperature strength and oxidation resistance, has been selected as a primary candidate material for structural use, particularly in Intermediate Heat Exchanger (IHX) which has an outlet temperature in the range of 850 to 950°C and an inner pressure from 5 to 20MPa. In order to qualify the material to be used at the operation condition for a designed service life of 60 years, a comprehensive scientific understanding of creep behavior at high temperature and low stress regime is necessary. In addition, the creep mechanism and the impact factors such as precipitates, grain size, and grain boundary characters need to be evaluated for the purpose of alloy design and development. In this study, thermomechanically processed specimens of alloy 617 with different grain sizes were fabricated, and creep tests with a systematic test matrix covering the temperatures of 850 to 1050°C and stress levels from 5 to 100MPa were conducted. Creep data was analyzed, and the creep curves were found to be unconventional without a well-defined steady-state creep. Very good linear relationships were determined for minimum creep rate versus stress levels with the stress exponents determined around 3-5 depending on the grain size and test condition. Activation energies were also calculated for different stress levels, and the values are close to 400kJ/mol, which is higher than that for self-diffusion in nickel. Power law dislocation climb-glide mechanism was proposed as the dominant creep mechanism in the test condition regime. Dynamic recrystallization happening at high strain range enhanced dislocation climb and

  4. Environment, energy and cities: Issues, problems and strategic options for urban settlements of the developing world. Chapter 2

    International Nuclear Information System (INIS)

    As the world has moved into the 21st century, energy-related challenges have already grown quite severe in cities throughout the world and in countries at all levels of development. From all corners of the globe, city residents are exposed to unhealthy levels of energy-generated pollution. Urban emissions are also having negative regional development impacts, reducing crop yields and forest integrity in wide areas across North America, Europe and Eastern Asia. Furthermore, the greenhouse gas emissions generated in the course of providing power to the world's cities are contributing significantly to the problem of global climate change. At the same time that the negative environmental impacts of urban energy consumption are manifesting themselves on local, regional and global levels, the demand for energy continues to grow. This relentless growth in demand for modern energy resources is understandable in cities throughout the developing world, where per capita consumption rates still remain comparatively low. Unfortunately, the environmental externalities generated by conventional energy systems are eroding the health and productivity of citizens in many developing country cities, and so new paths towards more efficient and sustainable patterns of energy consumption must be pursued in these areas. It has been estimated that about three-quarters of the world's commercial energy is consumed in cities. More specifically, over 75 per cent of carbon emissions from fossil fuel burning and cement manufacturing, and 76 per cent of industrial wood consumption, occur in urban areas. A primary function of the world energy system is to provide urban settlements with massive quantities of electricity, petrol and heat for use in commercial, transport and residential sectors (World Energy Assessment, UNDP, 2000). Urban societies in developing countries are dual in nature: in some segments of the society, incomes are quite high, and their energy-consumption patterns are similar to

  9. Chapter 11 Unexpected Turns and Twists in Structure/Function of PR-Proteins that Connect Energy Metabolism and Immunity

    KAUST Repository

    Narasimhan, Meena L.

    2009-01-01

    Innate immunity in plants is manifested by a complex array of antimicrobial processes that includes induction of sets of pathogenesis-related (PR) proteins. The availability of genomic data has made clear that each PR-protein family in a species is represented by several genes. Microarray data in public databases show that in most families, including the PR-5 family surveyed here, the expression of only few family members is defense associated. Genetic studies show that depending on their nutrient acquisition strategy, pathogens induce distinct but overlapping sets of PR genes, suggesting a connection to energy or resource allocation. PR-5 proteins have a clearly recognizable structure that is referred to as the thaumatin (THN) domain, which can be overlapped with mammalian Complement 1q-tumor necrosis factor (C1q-TNF) domains such as that of the mammalian hormone adiponectin. The occurrence of THN domain proteins is widespread. Similarities between THN domain proteins and mammalian C1q-TNF family proteins include their ligands and their subcellular locations. Osmotin (tobacco PR-5c) regulates energy balance signaling in mammalian cells by interaction with adiponectin receptors by a pathway that shares components with plant energy and stress signaling pathways. These data suggest additional roles for PR-5 proteins, as scaffolds and/or in signaling, particularly in regulating energy balance. © 2009 Elsevier Ltd. All rights reserved.

    Science.gov (United States)

    Michel, Patrick; DeMeo, Francesca E.; Bottke, William F.

    . Asteroids, like planets, are driven by a great variety of both dynamical and physical mechanisms. In fact, images sent back by space missions show a collection of small worlds whose characteristics seem designed to overthrow our preconceived notions. Given their wide range of sizes and surface compositions, it is clear that many formed in very different places and at different times within the solar nebula. These characteristics make them an exciting challenge for researchers who crave complex problems. The return of samples from these bodies may ultimately be needed to provide us with solutions. In the book Asteroids IV, the editors and authors have taken major strides in the long journey toward a much deeper understanding of our fascinating planetary ancestors. This book reviews major advances in 43 chapters that have been written and reviewed by a team of more than 200 international authorities in asteroids. It is aimed to be as comprehensive as possible while also remaining accessible to students and researchers who are interested in learning about these small but nonetheless important worlds. We hope this volume will serve as a leading reference on the topic of asteroids for the decade to come. We are deeply indebted to the many authors and referees for their tremendous efforts in helping us create Asteroids IV. We also thank the members of the Asteroids IV scientific organizing committee for helping us shape the structure and content of the book. The conference associated with the book, "Asteroids Comets Meteors 2014" held June 30-July 4, 2014, in Helsinki, Finland, did an outstanding job of demonstrating how much progress we have made in the field over the last decade. We are extremely grateful to our host Karri Muinonnen and his team. The editors are also grateful to the Asteroids IV production staff, namely Renée Dotson and her colleagues at the Lunar and Planetary Institute, for their efforts, their invaluable assistance, and their enthusiasm; they made life as

    The optimization of a nuclear energy system's performance requires an integrated consideration of multiple design goals - sustainability, safety and reliability (S&R), proliferation resistance and physical protection (PR&PP), and economics - as well as careful evaluation of trade-offs for different system design and operating parameters. Design approaches motivated by each of the goal areas (in isolation from the other goal areas) may be mutually compatible or in conflict. However, no systematic methodology approach has yet been developed to identify and maximize synergies and optimally balance conflicts across the possible design configurations and operating modes of a nuclear energy system. Because most Generation IV systems are at an early stage of development, design, and assessment, designers and analysts are only beginning to identify synergies and conflicts between PR&PP, S&R, and economics goals. The close coupling between PR&PP and S&R goals has motivated early attention within the Generation IV International Forum to their integrated consideration to facilitate the optimization of their effects and the minimization of potential conflicts. This paper discusses the status of this work.

  16. Instrumentation for Dosimetry. Chapter 21

    International Nuclear Information System (INIS)

    Measurements of absorbed dose (or air kerma) are required in varying situations in diagnostic radiology. The radiation fields vary from plain, slit and even point projection geometry, and may be stationary or moving, including rotational. Owing to the use of low photon energies for these fields, it is important that dosimeters have a satisfactory energy response. In general, the requirements for dosimeter accuracy are less stringent than those in radiation therapy; however, the dose and dose rate measurements cover a large range. Patient dosimetry (see Chapter 22) is a primary responsibility of the medical physicist specializing in diagnostic radiology and is required by legislation in many countries. Dose data are also required in the optimization of examinations for image quality and dose. Radiation measurement is also critical for occupational and public exposure control (see Chapter 24). Dose measurements are essential in acceptance testing and quality control (see Chapter 19). Several types of dosimeter can be used, provided that they have a suitable energy response, but typically, ionization chambers of a few cubic centimetres in volume, or solid state detectors specifically designed for such measurements, are used. If dosimeters are used to make measurements during an examination, they must not interfere with the examination. These devices are also used for determination of the half value layer (HVL). Special types of ionization chamber are employed for computed tomography (CT), mammography and interventional radiology dosimetry

  1. Energy consumption in industry, 1990 - 2035 - Scenarios I to IV for various sensitivities

    International Nuclear Information System (INIS)

    This comprehensive, illustrated report for the Swiss Federal Office of Energy (SFOE) takes a look at the results of a study with respect to industrial energy consumption which provided scenarios for future Swiss energy consumption. Four scenarios were elaborated: Continuation of present policy, increased co-operation between state and industry, more ambitious energy policy priorities and a scenario with even more ambitious goals - the so-called '2000 Watt Society'. For each of these scenarios several variants and a selection of sub-variants were defined, including increased prices, higher gross domestic product GDP, warmer climate and various carbon levies. The specific energy consumption of 16 different industrial sectors is examined and the effects of the various scenarios on several factors are considered. Data and results are presented in tabular and graphical form. Various measures that could influence energy consumption are listed and discussed, as are the modelling methods employed and the plausibility of the results obtained

  4. Validation of Nuclear Criticality Safety Software and 27 energy group ENDF/B-IV cross sections

    International Nuclear Information System (INIS)

    The validation documented in this report is based on calculations that were executed during June through August 1992, and was completed in June 1993. The statistical analyses in Appendix C and Appendix D were completed in October 1993. This validation gives Portsmouth NCS personnel a basis for performing computerized KENO V.a calculations using the Martin Marietta Nuclear Criticality Safety Software. The first portion of the document outlines basic information in regard to validation of NCSS using ENDF/B-IV 27-group cross sections on the IBM 3090 at ORNL. A basic discussion of the NCSS system is provided, some discussion on the validation database and validation in general. Then follows a detailed description of the statistical analysis which was applied. The results of this validation indicate that the NCSS software may be used with confidence for criticality calculations at the Portsmouth Gaseous Diffusion Plant. When the validation results are treated as a single group, there is 95% confidence that 99.9% of future calculations of similar critical systems will have a calculated Keff > 0.9616. Based on this result the Portsmouth Nuclear Criticality Safety Department has adopted the calculational acceptance criteria that a keff + 2σ ≤ 0.95 is safety subcritical. The validation of NCSS on the IBM 3090 at ORNL was extended to include NCSS on the IBM 3090 at K-25

  7. CO2 emissions reduction using energy conservation measures: EPA Region IV's experience

    International Nuclear Information System (INIS)

    EPA Region 4 concluded in a recent comparative environmental risk evaluation that global climate change could substantially impact the Southeast. To address this risk, Region 4 developed an action plan to promote cost-effective pollution prevention and reduce greenhouse gas emissions, The regional plan contains programs that aye specific to Region 4 as well as geographic components of the national Climate Change Action Plan. Sources of carbon dioxide emissions were targeted for pollution prevention based on an energy model that allows the user to create energy efficiency scenarios in four sectors: residential, commercial, industrial, and transportation. Activities were selected using the modeled information on sector reduction potentials and resource and cost-effectiveness criteria. Given the high level of uncertainty associated with climate change projections, the programs developed are all cost effective, prevent pollution and/or result in sound adaptation policies. Currently, policy makers at national, regional, and local levels are deciding on what types of energy efficiency programs to implement. The region's action plan is composed of several programs and approaches. The authors have developed implemented, and/or participated in the following: energy scenario model. EARTHWALK (residential energy conservation); energy conservation in affordable homes (new residences); Cool Communities Program (strategic tree planting and light colored surfaces); EPA's Green Lights Program; WAVE (water conservation), the Plant Protection Center; QUEST TO SAVE THE EARTH (outreach tools); energy and water use planning for the 1996 Olympic Games, and planning for sea-level rise. Reviewing the practices of the above programs will be the focus of this paper

    The year 2001 was marked by the extensive audit of energy research at PSI. The audit took place on 21/22 June, and nuclear energy research was evaluated by five international experts. It was possible to present the quality and relevance of our research in a convincing way. This, together with optimal use of the available resources in our department Nuclear Energy and Safety (NES), prompted the highly welcome result that the auditors attested a high degree of scientific quality to the NES projects in general, with some of them judged to be of world-class standard. They recommended all audited projects be maintained, adequate resources to be allocated accordingly and, if necessary, an increase of public funding in nuclear energy research to be granted to achieve this. Finally, it was recommended that energy research should be explicitly mentioned in the statement of the ultimate mission of PSI. At the level of 'daily work', efforts in several directions related to the future of the Hotlab were one of the main focuses during the past year. On the one hand, the safety-related backfitting of the facility (particularly in regard to fire protection) has been continued, and was coupled with intensive planning studies, and with a thorough radiological cleaning of the labs; this invariably led to some impediment to the current research activities. Despite external burdens, which have led to some delays and additional costs, three of the four refurbishment phases have been completed, and the corresponding laboratories were brought back into operation after inspection and approval by the regulatory authority HSK. Given the size and complexity of the project, progress must be considered very satisfactory. A list of scientific publications in 2000 is also provided

  14. Conclusion. Chapter 4

    International Nuclear Information System (INIS)

    Beginning 1992, January 1 Semipalatinsk test site was transforming into large research scientific center. The National Nuclear Center (NNC) was formed on the base of site's research enterprises. The principal problems of NNC are as follows: liquidation of nuclear tests consequences; liquidation of technological infrastructure for preparation and conducting of nuclear tests, creation of technology for radioactive wastes store; implementation of atomic energy development conception in Kazakhstan, etc. Program of site conversion constantly is expanding. In this chapter measures by rehabilitation of injured population are revealed. Taking into account radioecological situation, dose loadings, demographic indexes, sick rate and mortality of population on territories exposed to site's influence Government of Kazakhstan adopted Decree on declaration of these lands of zone of ecological catastrophe. Measures on improvement of radioecological situation are reduce to following ones: determination of irradiation doses received by population during testing period; study of existing radiation contamination; study of all possible sources for dose increasing and taking into account other ones; information of population about radioecological situation and about all consequences of nuclear tests. In 1992 Supreme Soviet of Republic of Kazakhstan worked out and adopted law On social defence of citizens suffered from consequences of nuclear tests on Semipalatinsk test site. It was distinguished four zones of radiation risk. The first zone is zone of extreme risk. It is part of territory subjected to radiation contamination with dose of influence on population above 100 rem during of total period of tests conducting. To this zone belong following inhabited settlements: Budene, Dolon', Cheremushki, Mostik, Sarzhal, Isa, Sarpan, Karakoryk, Zagotskot-2. Second zone is zone of maximal radiation risk. To this zone belong inhabited settlements of following districts: Abaj, Abraly, Beskargaj

    The department 'Nuclear Energy and Safety Research' (F4) at PSI carries the responsibility of performing the essential nuclear energy research in Switzerland. This research is part of the remit of PSI and follows government directive; about one-fifth of the Institute's Federal budget is allocated to this task. Currently about 190 persons are working in this field. Approximately 45% of the salary and investment costs (5.5 million CHF in the budget period 1996/97) are externally funded. This funding is provided primarily by the Swiss Utilities, the NAGRA and the safety authority HSK. The activities in nuclear research concentrate on three main domains: safety and safety related problems of operating plants, safety features of future reactor and fuel cycle concepts and waste management; another 4% of staff are addressing broader aspects of energy. At the end of 1996, a policy evaluation with the laboratory heads took place in order to redefine the direction of F4 activities. (author) figs., tabs., refs

    The XANES spectra of oxo- thio- and seleno-vanadium (IV) porphyrins together with ESR measurements on these compounds have been used to study the energy diagram of the 3d-like molecular orbitals. Possibilities for extracting an approximate value of the spin-orbit coupling constant are discussed on the basis of experimental data and theoretical results.

  17. Radiation Protection. Chapter 24

    International Nuclear Information System (INIS)

    Chapter 21, in describing basic radiation biology and radiation effects, demonstrates the need to have a system of radiation protection that allows the many beneficial uses of radiation to be realized while ensuring detrimental radiation effects are either prevented or minimized. This can be achieved with the twin objectives of preventing the occurrence of deterministic effects and of limiting the probability of stochastic effects to a level that is considered acceptable. In a radiology facility, consideration needs to be given to the patient, the staff involved in performing the radiological procedures, members of the public and other staff that may be in the radiology facility, carers and comforters of patients undergoing procedures, and persons who may be undergoing a radiological procedure as part of a biomedical research project. This chapter discusses how the objectives given above are fulfilled through a system of radiation protection and how such a system should be applied practically in a radiology facility

    Greenhouse heating is one of the most common uses of geothermal resources. Because of the significant heating requirements of greenhouses and their ability to use very low- temperature fluids, they are a natural application. The evaluation of a particular greenhouse project involves consideration of the structure heating requirements, and the system to meet those requirements. This chapter is intended to provide information on each of these areas.

    1978-09-01

    The guidelines laid out for the five subjects investigated in this series are to take a holistic view of energy conservation policies by describing the overall system in which they are implemented; provide analytical tools and sufficiently disaggregated data bases that can be adapted to answer a variety of questions by the users; identify and discuss some of the important issues behind successful energy conservation policy; and develop an energy conservation policy in depth. This report contains the design of a specific policy that addresses energy conservation in recreational travel. The policy is denoted as an ''Information System for the National Park Service.'' This work is based on prior examination of the characteristics of the recreational trip and decision making for the recreational experience. The examination revealed which aspects of the recreational travel system needed to be addressed to encourage energy-efficient modal decisions for recreational travel. This policy is briefly described in Section 1, the ''Summary of Initiative.'' A more detailed discussion of the policy follows. The material which led to the policy's formation is developed in Section 2: Importance and Impact of the Recreational Trip; Weekend Travel; The Flowchart: Decision Making for the Recreational Experience; Policy Development for Phase 1 ''Planning the Trip;'' and Objectives and Strategies for ''Planning the Trip.''

  12. The nature of the sunspot phenomenon. III - Energy consumption and energy transport. IV - The intrinsic instability of the magnetic configuration

    Parker, E. N.

    1975-01-01

    The basic relation is described between conversion of thermal energy into convective fluid motion and convective transport of thermal energy, and the equilibrium configuration of a sunspot's magnetic field is shown to be unstable to the hydromagnetic exchange instability. It is determined that heat transport necessarily accompanies convective driving of fluid motion and that the formation of cool sunspots requires convection extending coherently over several scale heights, a distance of at least 500 km. Several theoretical possibilities for sunspot stabilization are reviewed, and it is suggested that a suitable redistribution of cooling in the umbra may be the stabilization mechanism. It is believed that if cooling extends to a great depth in an elongated portion of a sunspot, the magnetic pressure on the boundary will be reduced, tending to reduce the elongation.

  13. Quality Management. Chapter 19

    International Nuclear Information System (INIS)

    This chapter introduces the principles and definitions of quality management systems (QMSs) for radiology facilities, to give a framework to assist in the setting up of such systems and to emphasize the role of the medical physicist in this context. While there is a diversity of terms currently in use to describe quality processes both generally and specifically within radiology, there is broad agreement that the effective management of radiation medicine services demands a quality culture that includes a systematic approach to the elements that govern the delivery of that service. Therefore, the concept of quality assurance (QA) within the radiological facility covers, in its widest sense, all those factors that affect the intended outcome, that is, a clinical diagnosis. The medical physicist has an important role in the overall QMS, especially, but not exclusively, with respect to the equipment performance. A worked example of a quality control (QC) programme is included at the end of the chapter, to demonstrate the depth of detail and involvement of the medical physicist

  15. Palaeoclimate. Chapter 6

    International Nuclear Information System (INIS)

    This chapter assesses palaeoclimatic data and knowledge of how the climate system changes over interannual to millennial time scales, and how well these variations can be simulated with climate models. Additional palaeoclimatic perspectives are included in other chapters. Palaeoclimate science has made significant advances since the 1970s, when a primary focus was on the origin of the ice ages, the possibility of an imminent future ice age, and the first explorations of the so-called Little Ice Age and Medieval Warm Period. Even in the first IPCC assessment, many climatic variations prior to the instrumental record were not that well known or understood. Fifteen years later, understanding is much improved, more quantitative and better integrated with respect to observations and modelling. After a brief overview of palaeoclimatic methods, including their strengths and weaknesses, this chapter examines the palaeoclimatic record in chronological order, from oldest to youngest. This approach was selected because the climate system varies and changes over all time scales, and it is instructive to understand the contributions that lower-frequency patterns of climate change might make in influencing higher-frequency patterns of variability and change. In addition, an examination of how the climate system has responded to large changes in climate forcing in the past is useful in assessing how the same climate system might respond to the large anticipated forcing changes in the future. Cutting across this chronologically based presentation are assessments of climate forcing and response, and of the ability of state-of-the-art climate models to simulate the responses. Perspectives from palaeoclimatic observations, theory and modelling are integrated wherever possible to reduce uncertainty in the assessment. Several sections also assess the latest developments in the rapidly advancing area of abrupt climate change, that is, forced or unforced climatic change that involves

    This chapter of the 2016 Billion-Ton Report provides an estimate of biomass potential at given minimum selling prices. This is not a projection of actual measured biomass or a simulation of commercial projects. Biomass potential is estimated based on 30 years of hourly local climate and strain-specific biophysical characteristics using the Biomass Assessment Tool (BAT), assuming sufficient available nutrients (including CO2). As is the case for terrestrial feedstocks, important resource analysis questions for algae include not only how much of the crop may be available but also what price might be needed to procure that supply. Identifying resource co-location opportunities for algal biofuel facilities has the potential to reduce costs, utilize waste resources, and focus attention on appropriate technologies and locations for commercialization.

  20. Converting the bis-FeIV state of the diheme enzyme MauG to Compound I decreases the reorganization energy for electron transfer.

    Science.gov (United States)

    Dow, Brian A; Davidson, Victor L

    2016-01-01

    The electron transfer (ET) properties of two types of high-valent hemes were studied within the same protein matrix; the bis-Fe(IV) state of MauG and the Compound I state of Y294H MauG. The latter is formed as a consequence of mutation of the tyrosine which forms the distal axial ligand of the six-coordinate heme that allows it to stabilize Fe(IV) in the absence of an external ligand. The rates of the ET reaction of each high-valent species with the type I copper protein, amicyanin, were determined at different temperatures and analysed by ET theory. The reaction with bis-Fe(IV) wild-type (WT) MauG exhibited a reorganization energy (λ) that was 0.39 eV greater than that for the reaction of Compound I Y295H MauG. It is concluded that the delocalization of charge over the two hemes in the bis-Fe(IV) state is responsible for the larger λ, relative to the Compound I state in which the Fe(V) equivalent is isolated on one heme. Although the increase in λ decreases the rate of ET, the delocalization of charge decreases the ET distance to its natural substrate protein, thus increasing the ET rate. This describes how proteins can balance different ET properties of complex redox cofactors to optimize each system for its particular ET or catalytic reaction. PMID:26494530

  1. Generic Performance Measures. Chapter 8

    International Nuclear Information System (INIS)

    The generic nuclear medicine imager, whether a gamma camera, single photon emission computed tomography (SPECT) system or positron emission tomography (PET) scanner, comprises several main components: a detection system, a form of collimation to select γ rays at specific angles, electronics and a computing system to create the map of the radiotracer distribution. This section discusses these components in more detail. The first stage of a generic nuclear medicine imager is the detection of the γ rays emitted by the radionuclide. In the case of PET, the radiation of interest are the 511 keV annihilation photons that result from the interaction of the positron emitted by the radionuclide with an electron in the tissue. For general nuclear medicine and SPECT, there is one or sometimes more than one γ ray of interest, with energies in the range of 400 keV. The γ rays are detected when they interact and deposit energy in the crystal(s) of the imaging system. There are two main types of detector: crystals that give off light that can be converted to an electrical signal when the γ ray interacts (‘scintillators’) and semiconductors, crystals that generate an electrical signal directly when the γ ray deposits energy in the crystal. Scintillation detectors include NaI(Tl), bismuth germanate (BGO) and lutetium oxyorthosilicate (LSO); semiconductor detectors used in nuclear medicine imagers include cadmium zinc telluride (CZT). Radiation detectors are described in more detail in Chapter 6

  2. New perspectives on nuclear power—Generation IV nuclear energy systems to strengthen nuclear non-proliferation and support nuclear disarmament

    International Nuclear Information System (INIS)

    Recently, nuclear power has received support from environmental and climate researchers emphasizing the need to address factors of global importance such as climate change, peace and welfare. Here, we add to previous discussions on meeting future climate goals while securing safe supplies of energy by discussing future nuclear energy systems in the perspective of strengthening nuclear non-proliferation and aiding in the process of reducing stockpiles of nuclear weapons materials. New nuclear energy systems, currently under development within the Generation IV (Gen IV) framework, are being designed to offer passive safety and inherent means to mitigate consequences of nuclear accidents. Here, we describe how these systems may also be used to reduce or even eliminate stockpiles of civil and military plutonium—the former present in waste from today's reactors and the latter produced for weapons purposes. It is argued that large-scale implementation of Gen IV systems would impose needs for strong nuclear safeguards. The deployment of Safeguards-by-Design principles in the design and construction phases can avoid draining of IAEA resources by enabling more effective and cost-efficient nuclear safeguards, as compared to the current safeguards implementation, which was enforced decades after the first nuclear power plants started operation. - Highlights: • Generation IV systems are developed for long-term sustainable electricity production. • New perspectives are capabilities to manage nuclear waste from nuclear power and aid disarmament. • Simulations show how a country can launch fast reactors to control and reduce plutonium stocks. • Safeguards-by-Design principles should be deployed, facilitating effective nuclear safeguards

    In the late 1970s, while the CERN community was busy preparing the SPS to operate as a collider and planning for LEP, people also had their eyes on the next chapter in the unfolding story of CERN.   That the LEP tunnel should be built with a future hadron collider in mind was a given by the end of the decade. But there had also been proposals to build large proton storage rings, or re-equip the ISR with superconducting magnets. Some people had suggested building an electron-proton collider at CERN, and there were ambitious plans looking far into the future at a possible Very Big Accelerator to be built somewhere in the world, which went by its acronym VBA. For the field of particle physics, with its very long lead times, this is part of the normal cycle, and while most of those options never came to fruition, this process did pave the way for the LHC. Today, with the LHC programme underway, the time has come for CERN to start seriously considering the options for its post-LHC future. Perhaps ...

  4. Image Reconstruction. Chapter 13

    International Nuclear Information System (INIS)

    This chapter discusses how 2‑D or 3‑D images of tracer distribution can be reconstructed from a series of so-called projection images acquired with a gamma camera or a positron emission tomography (PET) system [13.1]. This is often called an ‘inverse problem’. The reconstruction is the inverse of the acquisition. The reconstruction is called an inverse problem because making software to compute the true tracer distribution from the acquired data turns out to be more difficult than the ‘forward’ direction, i.e. making software to simulate the acquisition. There are basically two approaches to image reconstruction: analytical reconstruction and iterative reconstruction. The analytical approach is based on mathematical inversion, yielding efficient, non-iterative reconstruction algorithms. In the iterative approach, the reconstruction problem is reduced to computing a finite number of image values from a finite number of measurements. That simplification enables the use of iterative instead of mathematical inversion. Iterative inversion tends to require more computer power, but it can cope with more complex (and hopefully more accurate) models of the acquisition process

    Most geothermal fluids, because of their elevated temperature, contain a variety of dissolved chemicals. These chemicals are frequently corrosive toward standard materials of construction. As a result, it is advisable in most cases to isolate the geothermal fluid from the process to which heat is being transferred. The task of heat transfer from the geothermal fluid to a closed process loop is most often handled by a plate heat exchanger. The two most common types used in geothermal applications are: bolted and brazed. For smaller systems, in geothermal resource areas of a specific character, downhole heat exchangers (DHEs) provide a unique means of heat extraction. These devices eliminate the requirement for physical removal of fluid from the well. For this reason, DHE-based systems avoid entirely the environmental and practical problems associated with fluid disposal. Shell and tube heat exchangers play only a minor role in low-temperature, direct-use systems. These units have been in common use in industrial applications for many years and, as a result, are well understood. For these reasons, shell and tube heat exchangers will not be covered in this chapter.

  7. A new family of donor-acceptor systems comprising tin(IV) porphyrin and anthracene subunits: Synthesis, spectroscopy and energy transfer studies

    Indian Academy of Sciences (India)

    A Ashok Kumar; L Giribabu; Bhaskar G Maiya

    2002-12-01

    A new family of covalently linked `Sn(IV) porphyrin-anthracene’ diad (1), triad (2) and tetrad (3) donor-acceptor (D-A) systems have been designed and synthesized in good-to-moderate yields. While diad 1 possesses one anthracene subunit at the peripheral (meso) position of the tin(IV) porphyrin scaffold, triad 2 possesses two trans axial anthracene subunits at the tin(IV) centre. On the other hand, tetrad 3 is endowed with both the peripheral and axial anthracene subunits in its architecture. These D-A systems have been fully characterised by elemental analysis, FAB-MS, UV-Vis, 1H and 13C NMR and electrochemical methods. UV-Vis, NMR and redox data suggest the absence of intramolecular - interaction between the porphyrin and the anthracene/s in 1-3. Fluorescence from the anthracene subunit in 1 and 3 is found to be quenched in comparison with the fluorescence of free anthracene in four different solvents. This is not the case with compound 2. Excitation spectral data provides evidence for an intramolecular excitation energy transfer (EET) from the singlet anthracene to the porphyrin in 1 and 3. The energy transfer efficiency is in the order: 2 (almost negligible) < 3 (∼ 30%) < 1 (nearly quantitative), with the peripheral anthracene → porphyrin pathway being largely favoured. This orientation dependence of EET could be analysed using Forster’s dipole dipole mechanism.

    Before there is a funded space mission, there must be a present need for the mission. Space science and exploration are expensive, and without a well-defined and justifiable need, no one is going to commit significant funding for any space endeavor. However, as discussed in Chapter 1, applications of space technology and many and broad, hence there are many ways to determine and establish a mission need. Robotic science missions are justified by their science return. To be selected for flight, questions like these must be addressed: What is the science question that needs answering, and will the proposed mission be the most cost-effective way to answer it? Why does answering the question require an expensive space flight, instead of some ground-based alternative? If the question can only be answered by flying in space, then why is this approach better than other potential approaches? How much will it cost? And is the technology required to answer the question in hand and ready to use? If not, then how much will it cost and how long will it take to mature the technology to a usable level? There are also many ways to justify human exploration missions, including science return, technology advancement, as well as intangible reasons, such as national pride. Nonetheless, many of the questions that need answering, are similar to those for robotic science missions: Where are the people going, why, and will the proposed mission be the most cost-effective way to get there? What is the safest method to achieve the goal? How much will it cost? And is the technology required to get there and keep the crew alive in hand and ready to use? If not, then how much will it cost and how long will it take to mature the technology to a usable level? Another reason for some groups sending spacecraft into space is for profit. Telecommunications, geospatial imaging, and tourism are examples of proven, market-driven space missions and applications. For this specific set of users, the

    Exploration and extraction activities related to energy and mineral resources in the Borderlands—such as coal-fired power plants, offshore drilling, and mining—can create issues that have potentially major economic and environmental implications. Resource assessments and development projects, environmental studies, and other related evaluations help to understand some of these issues, such as power plant emissions and the erosion/denudation of abandoned mine lands. Information from predictive modeling, monitoring, and environmental assessments are necessary to understand the full effects of energy and mineral exploration, development, and utilization. The exploitation of these resources can negatively affect human health and the environment, its natural resources, and its ecological services (air, water, soil, recreation, wildlife, etc.). This chapter describes the major energy and mineral issues of the Borderlands and how geologic frameworks, integrated interdisciplinary (geobiologic) investigations, and other related studies can address the anticipated increases in demands on natural resources in the region.

The Johannesburg consensus: access to energy underpins development and poverty reduction The Johannesburg Plan of Implementation (JPOI) includes an emerging international consensus on the role of energy in sustainable development: 1) Energy services are an essential input to economic development and social progress, notably to achieving the Millennium Development Goals. Energy services are necessary for successful implementation of almost all sectoral development programmes, notably revenue generating activities, health, education, water, food security, agricultural development, etc. Increased access to energy fuels economic growth and poverty reduction. 'The lack of modern fuels and electricity in most developing countries entrenches poverty, constrains the delivery of social services, limits opportunities for women, and erodes environmental sustainability' (UN-Energy, 2005). 2) Under current economic conditions, provision of energy services to poor populations in many developing countries is not attractive to market actors. Experience in the decades before and after Johannesburg had amply demonstrated the positive and negative aspects of a purely market based approach to the provision of energy services. On the positive side, in the power sector for instance, privatization and deregulation had in many cases reduced expenditure of public funds in support of money losing public utilities. However, on the negative side, these attempts only rarely achieved improvement in the quality or reliability of service in urban areas (see Chapter 3). In almost no cases had they achieved improvement in the rates of access to electricity in rural

  11. Interactions of Radiation with Matter. Chapter 2

    International Nuclear Information System (INIS)

    This chapter deals with the physics of events that occur when photons and electrons interact with matter. These are the radiations that are important for diagnostic radiology, and only those interactions that result in their attenuation, absorption and scattering are dealt with. Other interactions, such as those with nuclei, are not considered here because they only occur for radiation that is higher in energy than that used for diagnostic radiology

    This Annual Site Environmental Report (ASER) for 2014 describes the environmental conditions related to work performed for the DOE at Area IV of the Santa Susana Field Laboratory (SSFL). The ETEC, a government-owned, company-operated test facility, was located in Area IV. The operations in Area IV included development, fabrication, operation and disassembly of nuclear reactors, reactor fuel, and other radioactive materials. Other activities in the area involved the operation of large-scale liquid metal facilities that were used for testing non-nuclear liquid metal fast breeder reactor components. All nuclear work was terminated in 1988, and all subsequent radiological work has been directed toward environmental restoration and decontamination and decommissioning (D&D) of the former nuclear facilities and their associated sites. Liquid metal research and development ended in 2002. Since May 2007, the D&D operations in Area IV have been suspended by the DOE, but the environmental monitoring and characterization programs have continued. Results of the radiological monitoring program continue to indicate that there are no significant releases of radioactive material from Area IV of SSFL. All potential exposure pathways are sampled and/or monitored, including air, soil, surface water, groundwater, direct radiation, transfer of property (land, structures, waste), and recycling.

  16. Chapter 8. Tensiometers

    International Nuclear Information System (INIS)

    The tensiometer is one of the oldest and most widely used instruments for irrigation scheduling around the world. Its use for measuring soil water potential has been documented since early last century (Livingston, 1908; Gardner et al., 1922; Richards, 1928; Or, 2001), and for irrigation scheduling of crops since the late 1950s (Richards and Marsh, 1961; Smajstrla et al., 1998). Many variations in diameter, length, pressure sensing and automation have since been developed. In recent years, gauges with solenoids and transducers have been used to control irrigation systems. Tensiometers do not measure soil water content. Tensiometers are sealed glass or polyvinyl chloride (PVC) tubes filled with degassed water, connected at one end to a porous ceramic cup and attached to a pressure gauge or sensor at the other. They are normally buried permanently in the soil at a specific depth. They measure the combined expression of matric and gravitational potentials in the field. Matric potential is the amount of energy with which water is held in the soil; it has zero or negative values. Tensiometers are not capable of measuring the osmotic potential due to salts in the soil water. When the water potential of the soil is low (more negative) compared with that inside the tensiometer, water moves from the tensiometer to the soil, creating a vacuum within the tensiometer which is equivalent to the suction from the soil. The water flow continues until equilibrium is reached. The tensiometer registers the vacuum as a pressure reading: the drier the soil the higher the absolute value of the pressure reading. Thus, tensiometer readings are typically positive values that can be seen as suction or tension values (A soil suction of 10 kPa is equivalent to a matric potential of -10 kPa). When irrigation or rainfall occurs, water is drawn back into the tube, decreasing the vacuum. Cassel and Klute (1986) described in detail the technique for measuring the in situ energy status of the water

  19. Radionuclide Production. Chapter 4

    International Nuclear Information System (INIS)

    All matter in the universe has its origin in an event called the ‘big bang’, a cosmic explosion releasing an enormous amount of energy about 14 billion years ago. Scientists believe that particles such as protons and neutrons, which form the building blocks of nuclei, were condensed as free particles during the first seconds. With the decreasing temperature of the expanding universe, the formation of particle combinations such as deuterium (heavy hydrogen) and helium occurred. For several hundred million years, the universe was plasma composed of hydrogen, deuterium, helium ions and free electrons. As the temperature continued to decrease, the electrons were able to attach to ions, forming neutral atoms and converting the plasma into a large cloud of hydrogen and helium gas. Locally, this neutral gas slowly condensed under the force of gravity to form the first stars. As the temperature and the density in the stars increased, the probability of nuclear fusion resulting in the production of heavier elements increased, culminating in all of the elements in the periodic table that we know today. As the stars aged, consuming their hydrogen fuel, they eventually exploded, spreading their contents of heavy materials around the universe. Owing to gravity, other stars formed with planets around them, composed of these heavy elements. Four and a half billion years have passed since the planet Earth was formed. In that time, most of the atomic nuclei consisting of unstable proton–neutron combinations have undergone transformation (radioactive decay) to more stable (non-radioactive) combinations. However, some with very long half-lives remain: 40K, 204Pb, 232Th and the naturally occurring isotopes of uranium

  20. Chapter 12. Public information

    International Nuclear Information System (INIS)

    The Nuclear Regulatory Authority of the Slovak Republic (UJD) is around to serve the public. This is a regulatory institution that furnishes truthful and independent information on nuclear safety of nuclear installations, including information on management of radioactive wastes, spent fuel, nuclear materials, control and record-keeping thereof, as well as information on other fuel cycle phases. UJD seeks to provide information in an orderly, accurate and comprehensible manner in such a way that it cannot be disclaimed, as the public has the right to know the truth. In formulating information, regularity, consistency and openness are of high importance, because information presented cannot serve a controversy. UJD furnishes information independently and separately from that issued by nuclear power plant operators. As a central administration authority, UJD provides on request, within the field of its responsibility, in particular the information on safety of nuclear energy installations independently from nuclear programme implementers, allowing the public and the media to check up the data and information thereon. A significant element of the information is the demonstration that the area of nuclear energy uses in the Slovak Republic has its binding rules and the compliance therewith is controlled by the state through an independent institution - UJD. As early as in 1995 the foundations laid were at UJD for the concept for broad public information on UJD activity and on safety of nuclear installations by opening UJD Information Centre. This Centre provides communication with the public and the media, thereby contributing to fashioning among the public a favourable image of the independent state supervision over nuclear safety. The Information Centre was extended in 2000. In 2000, 76 contributions on domestic and foreign UJD activities were sent in to Slovak press agencies, dailies and electronic media. UJD is together with the SUJB the publisher of the journal

  1. Dual Readout Calorimetry for High-Quality Energy Measurements - Chapter 3 R and D for Future Particle Physics Experiments (Task B)

    International Nuclear Information System (INIS)

    We report of the design, construction, commissioning, and beam tests of a prototype calorimeter. This calorimeter is of a novel design so as to equalize its response to electromagnetic and hadronic energy deposits of equal primary energy. Thus its response to jets is independent of the jet's electromagnetic versus hadronic composition. The beam tests show that the prototype satisfies the design requirements. The design, construction and the results of beam tests have been published in several papers in a refereed journal

  2. Solid waste as an energy source for the Northeast

    Energy Technology Data Exchange (ETDEWEB)

    Meier, P.M.; McCoy, T.H.

    1976-06-01

    This report, one of a series prepared for the BNL study of the Energy Future of the Northeastern United States, presents an assessment of the potential contribution of energy recovery from municipal refuse to energy supply in the region. A brief review of the present and likely future quantity and composition of municipal refuse and the technologies available for energy recovery (Chapters II and III) is followed by a comparison of the potential contributions to energy supply of the various recovery options including direct firing in utility boilers, pyrolysis to oil or gas, and steam generation for industrial process heat or district space heating (Chapter IV). The relationship of refuse energy recovery to market conditions for alternative energy sources is considered in Chapter V, which also includes an analysis of the impact of haul costs, interest rates, and delivered prices of the major fuels. Institutional barriers to implementation of energy recovery are reviewed in Chapter VI, and the environmental implications of the concept are addressed in Chapter VII. In the concluding chapters, scenarios of energy recovery are developed for 1985 and 2000, and the sensitivity of overall energy yield to projections and assumptions is examined. Although even under the most optimistic assumptions, refuse energy recovery is found to contribute only some 5 percent of total regional consumption, the economic and environmental benefits, coupled with the increasing difficulty of finding other refuse disposal alternatives, make energy recovery a very attractive policy choice for helping to relieve future energy supply difficulties in the Northeast.

  3. Chapter 1: Direct Normal Radiation

    Energy Technology Data Exchange (ETDEWEB)

    Myer, Daryl R.

    2016-04-15

    This chapter addresses the quantitative and qualitative aspects of the solar resource, the direct solar radiation. It discusses the total or integrated broadband direct beam extraterrestrial radiation (ETR). This total integrated irradiance is comprised of photons of electromagnetic radiation. The chapter also discusses the impact of the atmosphere and its effect upon the direct normal irradiance (DNI) beam radiation. The gases and particulates present in the atmosphere traversed by the direct beam reflect, absorb, and scatter differing spectral regions and proportions of the direct beam, and act as a variable filter. Knowledge of the available broadband DNI beam radiation resource data is essential in designing a concentrating photovoltaic (CPV) system. Spectral variations in the DNI beam radiation affect the performance of a CPV system depending on the solar cell technology used. The chapter describes propagation and scattering processes of circumsolar radiation (CSR), which includes the Mie scattering from large particles.

  9. Investigation of a Novel NDE Method for Monitoring Thermomechanical Damage and Microstructure Evolution in Ferritic-Martensitic Steels for Generation IV Nuclear Energy Systems

    Energy Technology Data Exchange (ETDEWEB)

    Nagy, Peter

    2013-09-30

    The main goal of the proposed project is the development of validated nondestructive evaluation (NDE) techniques for in situ monitoring of ferritic-martensitic steels like Grade 91 9Cr-1Mo, which are candidate materials for Generation IV nuclear energy structural components operating at temperatures up to ~650{degree}C and for steam-generator tubing for sodium-cooled fast reactors. Full assessment of thermomechanical damage requires a clear separation between thermally activated microstructural evolution and creep damage caused by simultaneous mechanical stress. Creep damage can be classified as "negligible" creep without significant plastic strain and "ordinary" creep of the primary, secondary, and tertiary kind that is accompanied by significant plastic deformation and/or cavity nucleation and growth. Under negligible creep conditions of interest in this project, minimal or no plastic strain occurs, and the accumulation of creep damage does not significantly reduce the fatigue life of a structural component so that low-temperature design rules, such as the ASME Section III, Subsection NB, can be applied with confidence. The proposed research project will utilize a multifaceted approach in which the feasibility of electrical conductivity and thermo-electric monitoring methods is researched and coupled with detailed post-thermal/creep exposure characterization of microstructural changes and damage processes using state-of-the-art electron microscopy techniques, with the aim of establishing the most effective nondestructive materials evaluation technique for particular degradation modes in high-temperature alloys that are candidates for use in the Next Generation Nuclear Plant (NGNP) as well as providing the necessary mechanism-based underpinnings for relating the two. Only techniques suitable for practical application in situ will be considered. As the project evolves and results accumulate, we will also study the use of this technique for monitoring other GEN IV

  13. Function of site. Chapter 2

    International Nuclear Information System (INIS)

    In Semipalatinsk test site's history there are two stages for nuclear tests. In first stage (1949-1962) when the nuclear tests have being conducted in atmosphere, and second one (1963-1989) when underground nuclear explosions have being carried out. There were 456 nuclear tests, from which 117 were both the surface and the atmospheric explosions and other underground ones. In the chapter general characteristics of atmospheric nuclear tests, conducted on Semipalatinsk test site in 1949-1962 (chronology of conducting, release energy and kinds of nuclear explosions) are presented in tabular form. Most powerful of explosion was test of hydro- nuclear (hydrogen) bomb - prototype of thermonuclear charge in 1955 with capacity 1.6 Mt. In 1990-1992 the target-oriented radioecological investigation of territory around Semipalatinsk test site was carried out. Specialists dividing all atmospheric explosions by rate local traces, forming out of test site into 4 groups: with very strong contamination, with strong contamination, with weak contamination, and with very weak contamination. To nuclear explosions with very strong contamination were attributed the four explosions carrying out in 29.08.1949, 24.09.1951, 12.08.1953, 24.08.1956. Estimations of radiological situation including external doses of radiation and environment contamination and content of radioactive substances in human body was given by 10 European experts in collaboration with Kazakstan scientists. Results of investigation show that during past period surface contamination, called by nuclear weapons' fissile products was subjected to considerable decay. External doses completely coincidence with natural background. Remains of long living radionuclides are insignificant as well, and in 1995 its approximately were equal to annual exposition doses. One of most damaged settlements is Chagan. On it territory 530 radioactive sources with doses capacity from 100 up to 400 μR/h. Scientists of Semipalatinsk defined

    In this short chapter, we discuss first the role of reliable and affordable electricity in underpinning economic development and in enabling the achievement of the MDGs in health and education. We then review some estimates of investment requirements for energy needs in sub Saharan Africa. In the next section we discuss briefly how financing sources for investment in the sector in sub-Saharan Africa are constrained. In the main and final section we list priority policies, which, if implemented, can help overcome these constraints so that increased amounts of investment begin to flow into the sector, resulting in the desired improvement in electricity services

    Merritt, David

    2015-01-01

    Direct numerical integrations of the two-dimensional Fokker-Planck equation are carried out for compact objects orbiting a supermassive black hole (SBH) at the center of a galaxy. As in Papers I-III, the diffusion coefficients incorporate the effects of the lowest-order post-Newtonian corrections to the equations of motion. In addition, terms describing the loss of orbital energy and angular momentum due to the 5/2-order post-Newtonian terms are included. In the steady state, captures are found to occur in two regimes that are clearly differentiated in terms of energy, or semimajor axis; these two regimes are naturally characterized as "plunges" (low binding energy) and "EMRIs," or extreme-mass-ratio inspirals (high binding energy). The capture rate, and the distribution of orbital elements of the captured objects, are presented for two steady-state models based on the Milky Way: one with a relatively high density of remnants and one with a lower density. In both models, but particularly in the second, the st...

    2012-10-01

    Full Text Available ABSTRACT: BACKGROUND : Proximal tibial fractures with high energy trauma are extremely complex injuries with significant associated soft-ti ssue damage. This Retrospective study was used to evaluate advantage of two stage reconstruct ions as a protocol in management of high- energy proximal tibia fractures regards of soft-tiss ue management, development of complications, and functional outcomes. MATERIALS AND METHODS : This retrospective study includes 40 patients who had sustained high energy P roximal tibial fractures were managed at our institute. In all patients, we placed immediate t emporary distraction external fixation with management of soft-tissue injuries with delayed def initive fixation. The mean clinical and radiographic follow-up was 1year (range 12-18 months , and functional outcome was assessed by knee society score. RESULTS : The mean follow-up is minimum 1 year (range 12-18 months with KSS was good in 26 cases (65%, fair in 10 cas es (25.0% and poor in 4(10.0% at latest follow-up. The complications includes 6 patients (15% suffered superficial infection, deep infection was observed in 4 patients (10%, 2 patient s had developed compartment syndrome. 2 patients had deep venous thrombosis. Malalignment i ncluded 4 (10% cases of residual varus and 3 (7.5% cases of residual valgus deformity. CONCLUSION : The use of this protocol, with the initial application of a temporary distraction ext ernal fixator followed by delayed internal fixation, is suggested for treatment of high energy tibial plateau fractures. The benefit of this protocol includes access to soft tissues, and prevent ion of further articular damage and relatively low rates of complications in patients who sustain high-energy proximal tibia fractures. In addition, this protocol allows use of MIPO technique which is based on combination of the principles of stability, restoration of anatom y and early motion, while eliminating the need for excessive soft tissue

    Up to this point, this handbook has described the use of X rays to form 2-D medical images of the 3-D patient. This process of reducing patient information by one dimension results in an image of superimposed tissues where important information might be obscured. Chapter 11 begins a section of the book involving the creation of cross-sectional medical images through computed tomography (CT), ultrasound and magnetic resonance imaging (MRI). This Chapter describes a number of special X ray imaging modalities and their associated techniques, and forms a transition between projection and cross-sectional imaging. The first of these special topics is dental radiography, which is characterized by a diversity of technology and innovation. The common intraoral radiograph of a single tooth has seen little fundamental change since the time of Roentgen and is, today, along with the simple chest radiograph, the most commonly performed radiographic examination. By contrast, the challenge to create an image of all the teeth simultaneously has placed dentistry at the cutting edge of technology, through the development of panographic techniques and, most recently, with the application of cone beam CT (CBCT). Moreover, the small size of the tooth and the consequent reduced need for X ray generation power promotes equipment mobility. The effect of the need for equipment mobility also forms a special topic that is examined in this chapter. Quantification of the composition of the body is another special X ray imaging technique. Dual energy X ray absorptiometry (DXA) is primarily used to derive the mass of one material in the presence of another, through knowledge of their unique X ray attenuation at different energies. DXA’s primary commercial application has been to measure body mineral density as an assessment of fracture risk and to diagnose osteoporosis; thus, the X ray energies used are optimized for bone density assessment. Currently, there are estimated to be over 50 000

  18. Chapter 1. Traditional marketing revisited

    OpenAIRE

    Lambin, Jean-Jacques

    2013-01-01

    The objective of this chapter is to review the traditional marketing concept and to analyse its main ambiguities as presented in popular textbooks. The traditional marketing management model placing heavy emphasis of the marketing mix is in fact a supply-driven approach of the market, using the understanding of consumers’ needs to mould demand to the requirements of supply, instead of adapting supply to the expectations of demand. To clarify the true role of marketing, a distinction is made b...

    This chapter assesses the literature on the economics of climate change adaptation, building on the Fourth Assessment Report (AR4) and the increasing role that economic considerations are playing in adaptation decisionmaking and policy. AR4 provided a limited assessment of the costs and benefits of adaptation, based on narrow and fragmented sectoral and regional literature (Adger et al, 2007). Substantial advances have been made in the economics of climate change adaptation after AR4.

    Groves, B; Sutherland, R; Kewley, L; Fischera, J; Leitherer, C; Brandl, B; van Breugal, W

    2007-01-01

    We combine the the stellar spectral synthesis code Starburst99, the nebular modelling code MAPPINGSIII, and a 1-D dynamical evolution model of HII regions around massive clusters of young stars to generate improved models of the spectral energy distribution (SED) of starburst galaxies. We introduce a compactness parameter, C, which characterizes the specific intensity of the radiation field at ionization fronts in HII regions, and which controls the shape of the far-IR dust re-emission, often referred to loosely as the dust ``temperature''. We also investigate the effect of metallicity on the overall SED and in particular, on the strength of the PAH features. We provide templates for the mean emission produced by the young compact HII regions, the older (10 - 100 Myr) stars and for the wavelength-dependent attenuation produced by a foreground screen of the dust used in our model. We demonstrate that these components may be combined to produce a excellent fit to the observed SEDs of star formation dominated ga...

    2008-01-15

    The combined pyrolysis and steam-gasification of petroleum vacuum residue was performed using a 5-kW aerosol-flow solar chemical reactor tested in a high-flux solar furnace in the temperature range 1420-1567 K. The feedstock was continuously injected as a liquid spray at 423 K into the reactor's cavity along with a coaxial steam flow at a H{sub 2}O/C molar ratio in the 1.1-7.2 range, and directly exposed to concentrated solar radiation at concentration ratios exceeding 1800 suns. The degree of chemical conversion after a single pass of 1-s residence time attained 50% at 1472 K, producing high quality syngas of composition 68% H{sub 2}, 15% CO, 14% CO{sub 2}, and 2% CH{sub 4}. The process performance indicators, namely, carbon conversion and energy efficiency were generally inferior to those obtained for the solar steam-gasification of petcoke under comparable operating conditions.

  13. The policy structure of the Dutch nuclear energy sector

    International Nuclear Information System (INIS)

    The main objective of this study has been to indicate the principle structures through which much of governmental nuclear policy is formed and to develop a model for the analysis of policy communication networks. The first chapter begins with a general outline of the international development of nuclear energy and gives an impression of the Dutch nuclear energy sector with special emphasis on the institutional aspects. In chapter II the author elaborates on the place of structural analysis in public policy analysis and argues that it is one of the indispensable elements of public policy analysis. Relations are treated in chapter III. Personal interlocks are given special attention because these are interrelated with financial, informational and other dependency relations and have a special communicative function in public policy-making. The different functions of the interlocks are 'translated' in graph theoretical concepts. Chapter IV introduces a method derived from graph analysis to analyse public policy networks. Several structural configurations are distinguished. In the same chapter an outline of the empirical research on the nuclear energy network will be given. In chapters V and VI the nuclear energy network is analysed, and in chapter VII the decision-making concerning some nuclear items is described in a general way. (Auth.)

  14. Chapter 12. Space Heating Equipment

    Energy Technology Data Exchange (ETDEWEB)

    Rafferty, Kevin D.

    1998-01-01

    The performance evaluation of space heating equipment for a geothermal application is generally considered from either of two perspectives: (a) selecting equipment for installation in new construction, or (b) evaluating the performance and retrofit requirements of an existing system. With regard to new construction, the procedure is relatively straightforward. Once the heating requirements are determined, the process need only involve the selection of appropriately sized hot water heating equipment based on the available water temperature. It is important to remember that space heating equipment for geothermal applications is the same equipment used in non-geothermal applications. What makes geothermal applications unique is that the equipment is generally applied at temperatures and flow rates that depart significantly from traditional heating system design. This chapter presents general considerations for the performance of heating equipment at non-standard temperature and flow conditions, retrofit of existing systems, and aspects of domestic hot water heating.

    Energy Technology Data Exchange (ETDEWEB)

    Stewart, J.; Todd, A.

    2015-01-01

    Residential behavior-based (BB) programs use strategies grounded in the behavioral social sciences to influence household energy use. Strategies may include providing households with real-time or delayed feedback about their energy use; supplying energy-efficiency education and tips; rewarding households for reducing their energy use; comparing households to their peers; and establishing games, tournaments, and competitions. BB programs often target multiple energy end uses and encourage energy savings, demand savings, or both. Savings from BB programs are usually a small percentage of energy use, typically less than 5%.

  17. Changes in Atmospheric Constituents and in Radiative Forcing. Chapter 2

    International Nuclear Information System (INIS)

    This chapter updates information taken from Chapters 3 to 6 of the IPCC Working Group I Third Assessment Report. It concerns itself with trends in forcing agents and their precursors since 1750, and estimates their contribution to the radiative forcing (RF) of the climate system. Discussion of the understanding of atmospheric composition changes is limited to explaining the trends in forcing agents and their precursors. Areas where significant developments have occurred since the TAR are highlighted. The chapter draws on various assessments since the TAR, in particular the 2002 World Meteorological Organization (WMO), United Nations Environment Programme (UNEP) Scientific Assessment of Ozone Depletion (2003) and the IPCC Technology and Economic Assessment Panel (TEAP) special report on Safeguarding the Ozone Layer and the Global Climate System (2005). The chapter assesses anthropogenic greenhouse gas changes, aerosol changes and their impact on clouds, aviation-induced contrails and cirrus changes, surface albedo changes and natural solar and volcanic mechanisms. The chapter reassesses the 'radiative forcing' concept (Sections 2.2 and 2.8), presents spatial and temporal patterns of RF, and examines the radiative energy budget changes at the surface. For the long-lived greenhouse gases (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluoro-carbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6), hereinafter collectively referred to as the LLGHGs; Section 2.3), the chapter makes use of new global measurement capabilities and combines long-term measurements from various networks to update trends through 2005. Compared to other RF agents, these trends are considerably better quantified; because of this, the chapter does not devote as much space to them as previous assessments (although the processes involved and the related budgets are further discussed in Sections 7.3 and 7

  18. Chapter 4: Geological Carbon Sequestration

    Energy Technology Data Exchange (ETDEWEB)

    Friedmann, J; Herzog, H

    2006-06-14

    Carbon sequestration is the long term isolation of carbon dioxide from the atmosphere through physical, chemical, biological, or engineered processes. The largest potential reservoirs for storing carbon are the deep oceans and geological reservoirs in the earth's upper crust. This chapter focuses on geological sequestration because it appears to be the most promising large-scale approach for the 2050 timeframe. It does not discuss ocean or terrestrial sequestration. In order to achieve substantial GHG reductions, geological storage needs to be deployed at a large scale. For example, 1 Gt C/yr (3.6 Gt CO{sub 2}/yr) abatement, requires carbon capture and storage (CCS) from 600 large pulverized coal plants ({approx}1000 MW each) or 3600 injection projects at the scale of Statoil's Sleipner project. At present, global carbon emissions from coal approximate 2.5 Gt C. However, given reasonable economic and demand growth projections in a business-as-usual context, global coal emissions could account for 9 Gt C. These volumes highlight the need to develop rapidly an understanding of typical crustal response to such large projects, and the magnitude of the effort prompts certain concerns regarding implementation, efficiency, and risk of the enterprise. The key questions of subsurface engineering and surface safety associated with carbon sequestration are: (1) Subsurface issues: (a) Is there enough capacity to store CO{sub 2} where needed? (b) Do we understand storage mechanisms well enough? (c) Could we establish a process to certify injection sites with our current level of understanding? (d) Once injected, can we monitor and verify the movement of subsurface CO{sub 2}? (2) Near surface issues: (a) How might the siting of new coal plants be influenced by the distribution of storage sites? (b) What is the probability of CO{sub 2} escaping from injection sites? What are the attendant risks? Can we detect leakage if it occurs? (3) Will surface leakage negate or

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents four scenarios concerning the development of energy consumption in the traffic sector for the period 1990 - 2035. The four scenarios - status quo, increased co-operation between the state and the economy with various energy levies, global reduction of energy consumption and, finally, scenario IV 'on the way to a 2000-Watt Society' - are briefly described. The areas examined include road, rail and air traffic as well as 'off-road' traffic. Infrastructure developments are commented on. The four scenarios are examined for various sensitivities including high gross domestic product GDP, high prices and warmer climate. Alternative fuels are looked at, as are further factors such as fuel tourism, pollutant emissions and costs. The results of the sensitivity analyses are compared and discussed and the necessary instruments are examined. This comprehensive report is completed with a comprehensive appendix

  20. Neptunium (IV) oxalate solubility

    International Nuclear Information System (INIS)

    The equilibrium solubility of neptunium (IV) oxalate in nitric/oxalic acid solutions was determined at 220C, 450C, and 600C. The concentrations of nitric/oxalic acid solutions represented a wide range of free oxalate ion concentration. A mathematical solubility model was developed which is based on the formation of the known complexes of neptunium (IV) oxalate. the solubility model uses a simplified concentration parameter which is proportional to the free oxalate ion concentration. The solubility model can be used to estimate the equilibrium solubility of neptunium (IV) oxalate over a wide range of oxalic and nitric acid concentrations at each temperature

  1. Chapter 12: Human microbiome analysis.

    Directory of Open Access Journals (Sweden)

    Xochitl C Morgan

    Full Text Available Humans are essentially sterile during gestation, but during and after birth, every body surface, including the skin, mouth, and gut, becomes host to an enormous variety of microbes, bacterial, archaeal, fungal, and viral. Under normal circumstances, these microbes help us to digest our food and to maintain our immune systems, but dysfunction of the human microbiota has been linked to conditions ranging from inflammatory bowel disease to antibiotic-resistant infections. Modern high-throughput sequencing and bioinformatic tools provide a powerful means of understanding the contribution of the human microbiome to health and its potential as a target for therapeutic interventions. This chapter will first discuss the historical origins of microbiome studies and methods for determining the ecological diversity of a microbial community. Next, it will introduce shotgun sequencing technologies such as metagenomics and metatranscriptomics, the computational challenges and methods associated with these data, and how they enable microbiome analysis. Finally, it will conclude with examples of the functional genomics of the human microbiome and its influences upon health and disease.

  2. Wien Automatic System Planning (WASP) Package. A computer code for power generating system expansion planning. Version WASP-IV. User's manual

    International Nuclear Information System (INIS)

    As a continuation of its efforts to provide methodologies and tools to Member States to carry out comparative assessment and analyse priority environmental issues related to the development of the electric power sector, the IAEA has completed a new version of the Wien Automatic System Planning (WASP) Package WASP-IV for carrying out power generation expansion planning taking into consideration fuel availability and environmental constraints. This manual constitutes a part of this work and aims to provide users with a guide to use effectively the new version of the model WASP-IV. WASP was originally developed in 1972 by the Tennessee Valley Authority and the Oak Ridge National Laboratory in the USA to meet the IAEA needs to analyse the economic competitiveness of nuclear power in comparison to other generation expansion alternatives for supplying the future electricity requirements of a country or region. Previous versions of the model were used by Member States in many national and regional studies to analyse the electric power system expansion planning and the role of nuclear energy in particular. Experience gained from its application allowed development of WASP into a very comprehensive planning tool for electric power system expansion analysis. New, improved versions were developed, which took into consideration the needs expressed by the users of the programme in order to address important emerging issues being faced by the electric system planners. In 1979, WASP-IV was released and soon after became an indispensable tool in many Member States for generation expansion planning. The WASP-IV version was continually upgraded and the development of version WASP-III Plus commenced in 1992. By 1995, WASP-III Plus was completed, which followed closely the methodology of the WASP-III but incorporated new features. In order to meet the needs of electricity planners and following the recommendations of the Helsinki symposium, development of a new version of WASP was

    2016-01-01

    In this work we study the characteristics of moving type IV radio bursts which extend to the hectometric wavelengths (interplanetary type IV or type IV IP bursts) and their relationship with energetic phenomena on the Sun. Our dataset comprised 48 Interplanetary type IV bursts observed by the Wind/WAVES in the 13.825 MHz?20 KHz frequency range. The dynamic spec tra of the RSTN, DAM, ARTEMIS-IV, CULGOORA, Hiraiso and IZMIRAN Radio-spectrographs were used to track the evolution of the events in the low corona; these were supplemented with SXR ?ux recordings from GOES and CME data from LASCO. Positional information for the coronal bursts were obtained by the Nan\\c{c}ay radioheliograph (NRH). We examined the relationship of the type IV events with coronal radio bursts, CMEs and SXR ?ares. The majority of the events (45) were characterized as compact; their duration was on average 106 min. This type of events were, mostly, associated with M and X class ?ares (40 out of 45) and fast CMEs; 32 of these events had CME...

  9. Energy-constrained open-system magmatic processes IV: Geochemical, thermal and mass consequences of energy-constrained recharge, assimilation and fractional crystallization (EC-RAFC)

    International Nuclear Information System (INIS)

    A wealth of geochemical and petrological data provide evidence that the processes of fractional crystallization, assimilation, and magma recharge (replenishment) dominate the chemical signatures of many terrestrial igneous rocks. Previous work [Spera and Bohrson, 2001 ; Bohrson and Spera, 2001] has established the importance of integrating energy, species and mass conservation into simulations of complex magma chamber processes. An extended version of the energy-constrained formulation, Energy-Constrained Recharge, Assimilation, Fractional Crystallization (EC-RAFC), tracks mass and compositional variations of melt, cumulates, and enclaves in a magma body undergoing simultaneous recharge, assimilation, and fractional crystallization [Spera and Bohrson, 2002]. Because many EC-RAFC results are distinct from those predicted by extant RAFC formulations, the primary goal of this paper is to present a range of geochemical and mass relationships for selected cases that highlight issues relevant to modern petrology. Among the plethora of petrologic problems that have important, well-documented analogues in nature are the geochemical distinctions that arise when a magma body undergoes continuous versus episodic recharge, the connection between erupted magmas and associated cumulate bodies, the behavior of recharge-fractionation dominated systems (RFC), thermodynamic conditions that promote the formation of enclaves versus cumulates, and the conditions under which magma bodies may be described as chemically homogeneous. Investigation of the effects of continuous versus episodic recharge for mafic magma undergoing RAFC in the lower crust indicates that the resulting geochemical trends for melt and solids are sensitive to the intensity and composition of recharge, suggesting that EC-RAFC may be used as a tool to distinguish the nature of the recharge events. Compared to the record preserved in melts, the geochemical and mass characteristics of solids associated with particular

    Tiessen, A.

    2014-09-01

    Retrocommissioning (RCx) is a systematic process for optimizing energy performance in existing buildings. It specifically focuses on improving the control of energy-using equipment (e.g., heating, ventilation, and air conditioning equipment and lighting) and typically does not involve equipment replacement. Field results have shown proper RCx can achieve energy savings ranging from 5% to 20%, with a typical payback of 2 years or less. A study conducted on behalf of Lawrence Berkeley National Laboratory analyzed data from 11 utilities operating RCx programs across the United States. The dataset included 122 RCx projects and more than 950 RCx measures.

  12. Generation IV nuclear energy systems: road map and concepts. 1. A Long-Term Energy Source Based on an HTGR Concept

    International Nuclear Information System (INIS)

    Today, the major component of the world's power consumption is based on natural gas and petroleum products. The major challenge for research and development of new energy sources is to find environmentally and economically acceptable ways to make a transition away from these increasingly scarce primary fuels. Technologies based on nuclear fission offer a promising solution. Reactor designs that capitalize on inherent safety characteristics are attractive choices for the further development of nuclear power. Such a system is the high temperature gas-cooled reactor (HTGR). Current research on the HTGR concept concentrates on a reactor with a pebble bed core. Analysis focuses on several areas. These include the following conceptual studies: 1. potential combinations of advanced fuel compositions and structural materials that improve performance characteristics of the pebble bed HTGR; 2. an advanced pebble bed HTGR design with a helium temperature elevated to >1300 K that provides the possibility of obtaining higher efficiency of the thermodynamic cycle; 3. prolonged operation of the pebble bed HTGR on a single fuel loading reaching high burnups. The results obtained from the listed foregoing studies are presented and discussed in this paper. As in all conventional reactors, during operation of the pebble bed, HTGR fissile material is being burned. This loss of fissile material in the fuel needs to be compensated for. Compensation of the fuel depletion can be performed by external actions, such as replacement or addition of new fuel, control rod motion, or internal conversion of fertile material into fissile material in the pebble bed HTGR core. The possibility of sustaining criticality during a long-term operation based on the mechanism of internal conversion has been demonstrated. The main idea of the present analysis consists of minimizing the external action required for the pebble bed HTGR toward prolonged operation on a single fuel loading. Flexibility of the

    Using the tellurium(IV) complex compounds as an example, we study the interrelation between the geometric structure and spectral luminescence properties. We find that, in the series of compounds of Te(IV), which are characterized by the island octahedral coordination of Te(IV) ions, the luminescence intensity depends on the degree of distortion of the Te(IV) coordination polyhedron, the Stokes shift, and the energy of the luminescence transition. We revealed that the considered series of Te(IV) compounds possess reversible thermochromic properties.

  14. Chapter IX: Stress phenomena in landscape

    International Nuclear Information System (INIS)

    This chapter consist of next sub-chapters: (1) Sources of stress phenomena and their reflection in landscape; (2) Impact of stress phenomena on natural resources and human hea; (3) Impact of stress phenomena on landscape. The different types of human activities and natural phenomena affect the environment. They are referred to by the general term of stress phenomena. There are the stress phenomena of natural character (the radon risk, landslides, avalanches, etc.) and anthropogenic phenomena determined or directly provoked by man (air and water pollution, emissions, etc.). They cause different environmental problems: they threaten the ecological and cultural priorities, but above all they threaten human health. National legislation and international conventions concerning the air protection lay down the regular inventory of emission of pollutants to atmosphere. Slovak Hydrometeorological Institute (SHMU) is responsible for such inventory. It is carried out in co-operation with several specialised institutions under the methodological guidance of the SHMU. The Register of Emissions and Pollution Sources (REZZO) was in operation at SHMU since 1985. It contains the data on emissions of the basic pollutants from stationary sources. This system was replaced by the National Emission Inventory System (NEIS) harmonised with the internationally accepted methodology (CORINAIR, EMEP, IPCC/FCCC). Sources of pollutants emitted to atmosphere are above all energetic and industrial productions, transport, fuel mining and transport, waste disposal and agriculture. Emissions in Slovakia reached their highest level by the end of the 1980's. Their consistent decrease is recorded since the 1990's. The cause of such developments is the overall recession connected with the decline of industrial production and consequently lower demand of the amount of produced energy. Simultaneously, the effects of legal instruments (Act No. 309/1991 of Coll. on protection of air against pollutants (The

    categories of such alterations are known: changes in chemical composition, radioactive decay and fission, migration of elements, deformation, depolymerization, ionization, leaching and hydrolysis. Thus, in principle, the modern materials used in recent times to imitate past or ancient objects are not naturally 'aged'. Among the laboratory processes used for art authenticity detection, the science based techniques of absolute dating play a predominant role, as they are considered highly reputable. Indeed, they are efficient in many, but not all, instances, for reasons explained below. This chapter briefly deals with luminescence and radiocarbon techniques, which exploit the above mentioned natural procedures of ionization and decay, respectively, as comprising the most frequently employed approaches in authenticity detection. Both techniques are regarded here as a means of investigating counterfeits.

  16. Chapter 5. Origin of Mineralization

    International Nuclear Information System (INIS)

    In this chapter author deals with the origin of uranium mineralization in Slovakia. There are discussed (1) Stratiform mineralization, particularly: (A) Uranium in Ti-rare earth elements (REE)-Zr placers in sandstone, (B) uranium mineralization in sandstone with abundant organic matter, (C) Uranium mineralization in phosphatic sandstone,(D) Cu±U mineralization (copper sandstone), (E) U-Mo mineralized horizons in volcanoclastic and volcanic rocks; (2) Vein mineralization, particularly: (F) Uranium mineralization in pegmatite, (G) Mo-W-(U-Ti-REE) mineralization in granite, (H) U-REE±Au mineralization in proximity of granite, (I) U±Mo and Cu mineralization cutting the permian sequences, (J) Uranium mineralization in the Neogene volcanics; and (3) Evolution of uranium mineralization. Uraninite occurrence in pegmatite of Dubrava deposit in Nizke Tatry Mts is the oldest manifestation of the uranium mineralization in the Western Carpathians. Its origin is related to the Hercynian magmatic activity. The most important uranium mineralization occurs in the Permian sequences. The stratiform mineralization is related to sandstones with abundant organic matter of Hronicum in the Kozie Chrbty Mts. or to volcanic and volcanoclastic rocks of Gemericum and Tatricum. The low-grade Permian ores display age ranging from (270 to 240±30) Ma. The Permian low-grade mineralization wa re-mobilized during the Alpine orogeny forming ore bodies of high-grade uranium mineralization especially on northern Gemericum and Tatricum of the Povazsky Inovec Mts. Big tectonic structures in ore deposits were favourable for remobilization. The younger re-mobilized mineralization overlaps the older low grade mineralization. U-Pb isotopic dating gave 130±20 Ma in high-grade ores of Gemericum in Novoveska Huta and 100±20 in high-grade ores of Tatricum in Kalnica. The Alpine granite with dissemination U-Ti-REE mineralization displays age 101±5 Ma according to Rb-Sr dating. As reliable U-Pb dating of U

    2016-08-01

    We study the characteristics of moving type IV radio bursts that extend to hectometric wavelengths (interplanetary type IV or type {IV}_{{IP}} bursts) and their relationship with energetic phenomena on the Sun. Our dataset comprises 48 interplanetary type IV bursts observed with the Radio and Plasma Wave Investigation (WAVES) instrument onboard Wind in the 13.825 MHz - 20 kHz frequency range. The dynamic spectra of the Radio Solar Telescope Network (RSTN), the Nançay Decametric Array (DAM), the Appareil de Routine pour le Traitement et l' Enregistrement Magnetique de l' Information Spectral (ARTEMIS-IV), the Culgoora, Hiraso, and the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN) Radio Spectrographs were used to track the evolution of the events in the low corona. These were supplemented with soft X-ray (SXR) flux-measurements from the Geostationary Operational Environmental Satellite (GOES) and coronal mass ejections (CME) data from the Large Angle and Spectroscopic Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO). Positional information of the coronal bursts was obtained by the Nançay Radioheliograph (NRH). We examined the relationship of the type IV events with coronal radio bursts, CMEs, and SXR flares. The majority of the events (45) were characterized as compact, their duration was on average 106 minutes. This type of events was, mostly, associated with M- and X-class flares (40 out of 45) and fast CMEs, 32 of these events had CMEs faster than 1000 km s^{-1}. Furthermore, in 43 compact events the CME was possibly subjected to reduced aerodynamic drag as it was propagating in the wake of a previous CME. A minority (three) of long-lived type {IV}_{{IP}} bursts was detected, with durations from 960 minutes to 115 hours. These events are referred to as extended or long duration and appear to replenish their energetic electron content, possibly from electrons escaping from the corresponding coronal

    International Nuclear Information System (INIS)

    In this chapter the international co-operation of the Nuclear Regulatory Authority of the Slovak Republic (UJD) in 1999 is reviewed. The Director General of the IAEA, Mr. Mohamed ElBaradei by his deputy for nuclear safety, Mr. Zikmund Domaratsky, upon the invitation of Minister of Foreign Affairs of the Slovak Republic Mr. Eduard Kukan, on 29 and 30 April 1999. Since 1999 Slovakia is represented in the Board of Governors of the IAEA. The Chairman of UJD was delegated by the Government of Slovakia to take the function of the governor. Co-operation between Slovakia and the IAEA in the field of technical projects is very successful. In the past year Slovakia was involved in 6 national and 23 regional projects. Significant part of regional projects related to the nuclear safety. Overall UJD organized 6 seminars and training courses with a broad international participation. These focused on radiation protection, fuel cycle, emergency regulations and utilization of radiation methods in oncology. There were 15 active research contracts in the field of agriculture, nuclear energy, safety of nuclear installations, physics, chemistry and RAW in 1999. A medium-term goal of UJD in the field of technical co-operation is a gradual transition to active international assistance in providing assistance to less developed countries. Within the technical projects of the IAEA assistance has been provided mainly to the countries of former of former Soviet Union. Other international activities and co-operation of UJD in 1999 are presented

    ECN has developed modules with Metal Wrap Through (MWT) cells glued on a electrical conductive Back Contact (BC) foil. The properties of the MWT-BC modules and a standard H-pattern module were investigated by outdoor IV tracing measurements. For both modules, the short circuit current is linear with the irradiance. The power output of the MWT-BC module is also linear with the irradiance, while the H-pattern module deviates from linearity at increasing irradiance. The deviation from linearity is explained by the higher series resistance of the H-pattern module due to the ohmic resistance of the busbars. The gain in yield due to the lower resistance of the MWT-BC module is calculated from the power output of the out-door IV tracing measurements at ECN (Amsterdam area, The Netherlands). The gain in yield will be even higher for southern countries and future modules having higher efficiency and improved light incoupling.

  4. Chapter 5-Radioactive Waste Management

    International Nuclear Information System (INIS)

    The ore pitchblende was discovered in the 1750's near Joachimstal in what is now the Czech Republic. Used as a colorant in glazes, uranium was identified in 1789 as the active ingredient by chemist Martin Klaproth. In 1896, French physicist Henri Becquerel studied uranium minerals as part of his investigations into the phenomenon of fluorescence. He discovered a strange energy emanating from the material which he dubbed 'rayons uranique.' Unable to explain the origins of this energy, he set the problem aside. About two years later, a young Polish graduate student was looking for a project for her dissertation. Marie Sklodowska Curie, working with her husband Pierre, picked up on Becquerel's work and, in the course of seeking out more information on uranium, discovered two new elements (polonium and radium) which exhibited the same phenomenon, but were even more powerful. The Curies recognized the energy, which they now called 'radioactivity,' as something very new, requiring a new interpretation, new science. This discovery led to what some view as the 'golden age of nuclear science' (1895-1945) when countries throughout Europe devoted large resources to understand the properties and potential of this material. By World War II, the potential to harness this energy for a destructive device had been recognized and by 1939, Otto Hahn and Fritz Strassman showed that fission not only released a lot of energy but that it also released additional neutrons which could cause fission in other uranium nuclei leading to a self-sustaining chain reaction and an enormous release of energy. This suggestion was soon confirmed experimentally by other scientists and the race to develop an atomic bomb was on. The rest of the development history which lead to the bombing of Hiroshima and Nagasaki in 1945 is well chronicled. After World War II, development of more powerful weapons systems by the United States and the Soviet Union continued to advance nuclear science. It was this defense

  20. Chapter 8: The credibility crisis

    International Nuclear Information System (INIS)

    In the credibility crisis, a generalized state of conflicting cognitions is probably prevalent, along with possible individual and social pathologies. These cognitive conflicts and emotional traumas are linked to both the characteristics of Chernobyl as a human-made disaster and the specific nature of Chernobyl as a nuclear disaster. Three major elements as constituents of this nature are identified: The rupture of a social contract, the loss of a socially valued object, and the sudden removal of established distances. Further research and basic information are needed in this area where little specific observation is reported. A better grasp of the impact of nuclear energy on our societies can lead to better adapted policy, increased local and social solidarity, more decentralized initiative and risk management, and better organized primary prevention in nuclear disaster.

A chiller plant encompasses a chiller--or multiple chillers--and associated auxiliary equipment. This protocol primarily covers electric-driven chillers and chiller plants. It does not include thermal energy storage and absorption chillers fired by natural gas or steam, although a similar methodology may be applicable to these chilled water system components. Chillers provide mechanical cooling for commercial, institutional, multiunit residential, and industrial facilities. Cooling may be required for facility heating, ventilation, and air conditioning systems or for process cooling loads (e.g., data centers, manufacturing process cooling). The vapor compression cycle, or refrigeration cycle, cools water in the chilled water loop by absorbing heat and rejecting it to either a condensing water loop (water cooled chillers) or to the ambient air (air-cooled chillers).

    Solutions and solid complexes of Tb(IV) tellurate and periodate were prepared on the basis of synthesis methods developed. Data provided by X-ray diffraction of powder and electron spectroscopy suggest individuality of Tb(IV) derivatives. Data on transition energies with charge transfer in absorption spectra of the complexes and literature data permit defining the following stability series of Tb(IV) complexes: heteropolytungstates feature the highest stability, then stability decreases to periodate and subsequently to tellurite and carbonate complexes

  5. Handbook on superconductivity: the large-scale applications. Chapter IV. Stability

    International Nuclear Information System (INIS)

    One way to cool a magnet is to immerse it in a bath of liquid helium. Boiling helium is a favorite because of helium's large latent heat of vaporization, but as in all boiling heat transfer, blanketing of the surface by vapor (film boiling) limits the attainable heat transfer. A second way to cool is with single-phase supercritical helium. To make the heat transfer high, helium in turbulent flow is forced through hollow conductors. A third way to cool is with He-II at atmospheric pressure. The He-II phase of helium, which remains liquid right down to absolute zero, has some remarkable properties that distinguish it from all other liquids, including the normal liquid phase of helium, He-I. These properties have excited great interest in He-II as a coolant for superconducting magnets. Each of these ways of cooling leads to a class of specialized problems that are discussed in detail. A somewhat different way to forestall quenches is to pot the conductor in a material that tightly confines it and to cool it indirectly by conduction to helium not directly in contact with it. The special problems of this approach are discussed as well

    International Nuclear Information System (INIS)

    Nuclear Regulatory Authority of the Slovak Republic (UJD) being the central state body of the Slovak Republic provides in the framework of its competence the information on safety of nuclear facilities independently of their operators. UJD enables the public and mass media to review data and information on nuclear facilities. The important point of being informed is to prove, that the area of nuclear energy use has its obligatory rules in the Slovak Republic and their observing is controlled by state through the independent institution - UJD. An establishment of UJD Information Centre as early as in 1995, the basis of conception of informing the public on UJD activities and on nuclear facilities safety was created. The Centre secures the communication with the public and mass media that helps create a positive picture on the independent regulatory authority supervising nuclear safety. Over the last year, the important attention was given to implementation of Act No 211/2000 of Coll. on Free Access to Information that entered into force on 1 January 2001. The Act established the right of the public to access to information at the disposal of state bodies, i.e. inter al ia UJD, territorial self-governing bodies and other bodies managing the public resources. The Act obliges the state bodies to make basic and standard information on their activities automatically public, in order to make the information generally available and to make public administration easier and more transparent. On 4 January 2001 UJD has issued the Regulation on Implementation of Act No 211/2000 of Coll. on Free Access to Information as amended regulating the implementation of the Act in the conditions of UJD. The information boards with the basic data on making information available pursuant to the Act were established in UJD premises in Bratislava and in Trnava.

  11. Technical data summary: Uranium(IV) production using a large scale electrochemical cell

    International Nuclear Information System (INIS)

    This Technical Data Summary outlines an electrochemical process to produce U(IV), in the form of uranous nitrate, from U(VI), as uranyl nitrate. U(IV) with hydrazine could then be used as an alternative plutonium reductant to substantially reduce the waste volume from the Purex solvent extraction process. This TDS is divided into three parts. The first part (Chapters I to IV) generally describes the electrochemical production of U(IV). The second part (Chapters V to VII) describes a pilot scale U(IV) production facility that was constructed and operated at an engineering semiworks area of SRP, referred to as TNX. The lst part (Chapter VIII) describes a preliminary design for a full-scale facility that would meet the projected need for U(IV) as a reductant in SRP's separations processes. The preliminary design was described in a Basic Data Summary for the U(IV) production facility, and a Venture Guidance Appraisal (VGA) was prepared from the Basic Data Summary. The VGA for the U(IV) process showed that because of the large capital investment required, this approach to waste reduction was not economically competitive with another alternative that required only modifying the ongoing Purex process at no additional capital cost. However, implementing he U(IV) process as part of an overall canyon renovation, presently scheduled for the 1990's, may be economically attractive. The purpose of this TDS is therefore to bring together the information and experience obtained thus far in the U(IV) program so that a useful body of information will be available to support any future development of this process

    The Sputnik IV launch occurred on May 15, 1960. On May 19, an attempt to deorbit a 'space cabin' failed and the cabin went into a higher orbit. The orbit of the cabin was monitored and Moonwatch volunteer satellite tracking teams were alerted to watch for the vehicle demise. On September 5, 1962, several team members from Milwaukee, Wisconsin made observations starting at 4:49 a.m. of a fireball following the predicted orbit of Sputnik IV. Requests went out to report any objects found under the fireball path. An early morning police patrol in Manitowoc had noticed a metal object on a street and had moved it to the curb. Later the officers recovered the object and had it dropped off at the Milwaukee Journal. The Moonwarch team got the object and reported the situation to Moonwatch Headquarters at the Smithsonian Astrophysical Observatory. A team member flew to Cambridge with the object. It was a solid, 9.49 kg piece of steel with a slag-like layer attached to it. Subsequent analyses showed that it contained radioactive nuclei produced by cosmic ray exposure in space. The scientists at the Observatory quickly recognized that measurements of its induced radioactivity could serve as a calibration for similar measurements of recently fallen nickel-iron meteorites. Concurrently, the Observatory directorate informed government agencies that a fragment from Sputnik IV had been recovered. Coincidently, a debate in the UN Committee on Peaceful Uses of Outer Space involved the issue of liability for damage caused by falling satellite fragments. On September 12, the Observatory delivered the bulk of the fragment to the US Delegation to the UN. Two days later, the fragment was used by US Ambassador Francis Plimpton as an exhibit that the time had come to agree on liability for damage from satellite debris. He offered the Sputnik IV fragment to USSR Ambassador P.D. Morozov, who refused the offer. On October 23, Drs. Alla Massevitch and E.K. Federov of the USSR visited the

    The objectives of this research project are to significantly extend the theoretical foundation and the modeling of radiation-induced microstructural changes in structural materials used in Generation IV nuclear reactors, and to derive from these microstructure models the constitutive laws for void swelling, irradiation creep and stress-induced swelling, as well as changes in mechanical properties. The need for the proposed research is based on three major developments and advances over the past two decades. First, new experimental discoveries have been made on void swelling and irradiation creep which invalidate previous theoretical models and empirical constitutive laws for swelling and irradiation creep. Second, recent advances in computational methods and power make it now possible to model the complex processes of microstructure evolution over long-term neutron exposures. Third, it is now required that radiation-induced changes in structural materials over extended lifetimes be predicted and incorporated in the design of Generation IV reactors. Our approach to modeling and data analysis is a dual one in accord with both the objectives to simulate the evolution of the microstructure and to develop design equations for macroscopic properties. Validation of the models through data analysis is therefore carried out at both the microscopic and the macroscopic levels. For the microstructure models, we utilize the transmission electron microscopy results from steels irradiated in reactors and from model materials irradiated by neutrons as well as ion bombardments. The macroscopic constitutive laws will be tested and validated by analyzing density data, irradiation creep data, diameter changes of fuel elements, and post-irradiation tensile data. Validation of both microstructure models and macroscopic constitutive laws is a more stringent test of the internal consistency of the underlying science for radiation effects in structural materials for nuclear reactors.

  19. SOLAR TRANSITION REGION LINES OBSERVED BY THE INTERFACE REGION IMAGING SPECTROGRAPH: DIAGNOSTICS FOR THE O IV AND Si IV LINES

    International Nuclear Information System (INIS)

    The formation of the transition region O IV and Si IV lines observable by the Interface Region Imaging Spectrograph (IRIS) is investigated for both Maxwellian and non-Maxwellian conditions characterized by a κ-distribution exhibiting a high-energy tail. The Si IV lines are formed at lower temperatures than the O IV lines for all κ. In non-Maxwellian situations with lower κ, the contribution functions are shifted to lower temperatures. Combined with the slope of the differential emission measure, it is possible for the Si IV lines to be formed at very different regions of the solar transition region than the O IV lines; possibly close to the solar chromosphere. Such situations might be discernible by IRIS. It is found that photoexcitation can be important for the Si IV lines, but is negligible for the O IV lines. The usefulness of the O IV ratios for density diagnostics independently of κ is investigated and it is found that the O IV 1404.78 Å/1399.77 Å ratio provides a good density diagnostics except for very low T combined with extreme non-Maxwellian situations

  6. Type IV collagen

    International Nuclear Information System (INIS)

    Type IV collagen is a highly specialized form of collagen found only in basement membranes. It is one of the major components of all basement membranes together with the glycoproteins laminin, nidogen, entactin, and heparan sulfate proteoglycan. Basement membranes are ubiquitous, thin, sheetlike structures found frequently under epithelial and endothelial cell linings but also surrounding many cell types such as muscle, nerve, and fat. They function as a selective filtration barrier for macromolecules, for example, in the kidney, blood--brain barrier, and placenta, but also separate extracellular matrix from epithelial or endothelial cell layers as in gut, skin, cornea, lung, and blood vessels. Indications that basement membranes contained a collagen came from X-ray studies of intact basement membranes as early as 1951. Later, hydroxyproline and then hydroxylysine were detected in amino acid compositions of whole basement membranes. Because of the insolubility of basement membrane components, attempts were made to solubilize the collagen using Pronase, a method that had proved useful for type I collagen. The material that was isolated and characterized was clearly different from the other interstitial collagens known at that time, i.e., α1(I), α1(II), and α1(III). Basement membrane collagen was therefore designated type IV collagen

    Our civilization is in an inflection moment. Our current decisions will lead us to drastic changes in the planet climate or to cleaner and more sustainable energy generation models. In a certain moment in the evolution of our society, we have privileged the productivity instead of the reasonable use of the planet's resources. This option has been leading us to a situation in which these resources are seriously jeopardized. New models of energy generation and use should be discussed and adopted in order to reverse this process. The electric-power consumption is not constant through time and it must be generated at the moment it is going to be used. There are moments of great idleness in the electric-power generation system, counterbalanced by high demand moments. This characteristic has induced us to the construction of a model of great generation capacity that remains without use most of the time, producing huge financial and environmental impacts. In this article, we discuss the environmental, financial and energy viability of using the idle capacity of the electric-power system to, through water steam electrolysis, produce hydrogen, which would be reconverted into electric power in peak moments by a fuel cell. In this study, we aim at investigating the viability of associating a SOFC (Solid Oxide Fuel Cell), acting as an electrolysis bow, to a generation IV reactor, in order to produce hydrogen from superheated water steam in the cooling of the reactor, which will be converted into electric power via SOFC (Solid Oxide Fuel Cell) in peak moments. The method used in this investigation was to study the electric charge variation consumed in a day, randomly selected in relation to the hour of the day, to launch a curve into a diagram 'Demand x hour of the day', to establish the peak moments, the minimum moments, and the average consumption, and, based on these data and geometrically, predict the viability of using the energetic potential of the moments

  15. Basic Physics for Nuclear Medicine. Chapter 1

    International Nuclear Information System (INIS)

    The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters

    Science.gov (United States)

    Elliott, Diane G.; Wiens, Gregory D.; Hammell, K. Larry; Rhodes, Linda D.

    2014-01-01

    Bacterial kidney disease (BKD) of salmonid fishes, caused by Renibacterium salmoninarum, has been recognized as a serious disease in salmonid fishes since the 1930s. This chapter discusses the occurrence and significance, etiology, and pathogenesis of BKD. It then describes the different vaccination procedures and the effects and side-effects of vaccination. Despite years of research, however, only a single vaccine has been licensed for prevention of BKD, and has demonstrated variable efficacy. Therefore, in addition to a presentation of the current status of BKD vaccination, a discussion of potential future directions for BKD vaccine development is included in the chapter. This discussion is focused on the unique characteristics of R. salmoninarum and its biology, as well as aspects of the salmonid immune system that might be explored specifically to develop more effective vaccines for BKD prevention.

    2013-01-01

    It is generally accepted that exposure to fine particulate matter may increase risk for human morbidity and mortality. Until recently, population health related studies examining the effects of particulate matter on human health generally examined anthropogenic (industry and combustion by-products) sources with few studies considering contributions from natural sources. This chapter provides an overview of naturally occurring inorganic mineral dust research and associated human health ailments and some of the challenges in elucidating the etiological mechanisms responsible.

    OpenAIRE

    Lambin, Jean-Jacques

    2013-01-01

    The objective of this chapter is to raise the issue of marketing accountability. A central problem in business today is that marketing lacks the kind of accountability and metrics common to the rest of the corporation. For a very long time, this imprecision has been tolerated and has been excused because marketing was supposed to be inherently “creative”. Yet, as marketing consumes a larger and larger portion of the firm budget, the imperative grows to quantify marketing’s direct contribution...

    demonstrates that positive but not negative memories show a reminiscence bump and that memories cluster at the beginning of extended time periods. The current study tested the hypotheses that (1) ages marking the beginning of positive but not negative chapters produce a bump, and that (2) specific memories are...... over-represented at the beginning of chapters. Potential connections between chapters and the cultural life script are also examined. Adult participants first divided their life story into chapters and identified their most positive and most negative chapter. They then recalled a specific memory from...... both their most positive and most negative chapter. As predicted, the beginning age of positive but not negative chapters produced a bump and specific memories tended to cluster at chapter beginnings. The results support the idea that chapters guide the search for specific memories and that the...

  2. Management of Therapy Patients. Chapter 20

    International Nuclear Information System (INIS)

    The basic principles of radiation protection and their implementation as they apply to nuclear medicine are covered in general in Chapter 3. This chapter will look at the specific case of nuclear medicine used for therapy. In addition to the standards discussed in Chapter 3, specific guidance on the release of patients after radionuclide therapy can be found in the IAEA’s Safety Reports Series No. 63 [20.1]. When the patient is kept in hospital following radionuclide therapy, the people at risk of exposure include hospital staff whose duties may or may not directly involve the use of radiation. This can be a significant problem. However, it is generally felt that it can be effectively managed with well trained staff and appropriate facilities. On the other hand, once the patient has been released, the groups at risk include members of the patient’s family, including children, and carers; they may also include neighbours, visitors to the household, co-workers, those encountered in public places, on public transport or at public events, and finally, the general public. It is generally felt that these risks can be effectively mitigated by the radiation protection officer (RPO) with patient-specific radiation safety precaution instructions

  3. A Survey of Geologic Resources. Chapter 11

    Science.gov (United States)

    Edmonson, Jennifer; Rickman, Doug

    2012-01-01

    This chapter focuses on the resources available from the Moon itself: regolith, geologically concentrated materials, and lunar physical features that will enable habitation and generation of power on the surface. This chapter briefly covers the formation of the Moon and thus the formation of the crust of the Moon, as well as the evolution of the regolith. The characteristics of the regolith are provided in some detail, including its mineralogy and lithology. The location of high concentrations of specific minerals or rocks is noted. Other ideal locations for in situ resource utilization technology and lunar habitation are presented. This chapter is intended to be a brief review of current knowledge, and to serve as a foundational source for further study. Each concept presented here has a wealth of literature associated with it; the reader is therefore directed to that literature with each discussion. With great interest in possible manned lunar landings and continued study of the Moon by multiple satellites, the available information changes regularly.

  5. Introduction to meteorological measurements and data handling for solar energy applications. Task IV-Development of an insolation handbook and instrument package

    Energy Technology Data Exchange (ETDEWEB)

    None

    1980-10-01

    Recognizing a need for a coordinated approach to resolve energy problems, certain members of the Organization for Economic Cooperation and Development (OECD) met in September 1974 and agreed to develop an International Energy Program. The International Energy Agency (IEA) was established within the OECD to administer, monitor and execute this International Energy Program. In July 1975, Solar Heating and Cooling was selected as one of the sixteen technology fields for multilateral cooperation. Five project areas, called tasks, were identified for cooperative activities within the IEA Program to Develop and Test Solar Heating and Cooling Systems. The objective of one task was to obtain improved basic resource information for the design and operation of solar heating and cooling systems through a better understanding of the required insolation (solar radiation) and related weather data, and through improved techniques for measurement and evaluation of such data. At the February 1976 initial experts meeting in Norrkoeping, Sweden, the participants developed the objective statement into two subtasks. (1) an insolation handbook; and (2) a portable meteorological instrument package. This handbook is the product of the first subtask. The objective of this handbook is to provide a basis for a dialogue between solar scientists and meteorologists. Introducing the solar scientist to solar radiation and related meteorological data enables him to better express his scientific and engineering needs to the meteorologist; and introducing the meteorologist to the special solar radiation and meteorological data applications of the solar scientist enables him to better meet the needs of the solar energy community.

    Dewitt, H. E.; Hubbard, W. B.

    1976-01-01

    A large quantity of data on the thermodynamic properties of hydrogen-helium metallic liquids have been obtained in extended computer calculations in which a Monte Carlo code essentially identical to that described by Hubbard (1972) was used. A model free energy for metallic hydrogen with a relatively small mass fraction of helium is discussed, taking into account the definition of variables, a procedure for choosing the free energy, values for the fitting parameters, and the evaluation of the entropy constants. Possibilities concerning a use of the obtained data in studies of the interiors of the outer planets are briefly considered.

  8. An Integrated Safety Assessment Methodology for Generation IV Nuclear Systems

    Energy Technology Data Exchange (ETDEWEB)

    Timothy J. Leahy

    2010-06-01

    The Generation IV International Forum (GIF) Risk and Safety Working Group (RSWG) was created to develop an effective approach for the safety of Generation IV advanced nuclear energy systems. Early work of the RSWG focused on defining a safety philosophy founded on lessons learned from current and prior generations of nuclear technologies, and on identifying technology characteristics that may help achieve Generation IV safety goals. More recent RSWG work has focused on the definition of an integrated safety assessment methodology for evaluating the safety of Generation IV systems. The methodology, tentatively called ISAM, is an integrated “toolkit” consisting of analytical techniques that are available and matched to appropriate stages of Generation IV system concept development. The integrated methodology is intended to yield safety-related insights that help actively drive the evolving design throughout the technology development cycle, potentially resulting in enhanced safety, reduced costs, and shortened development time.

    Stewart, Lawrence G.

    1979-09-01

    The report is designed to make a beginning in broadening the scope of the comprehensive manpower information system for energy research, development, and demonstration, so that it could cover all manpower related to energy. It develops a plan for this extension, including determining which taxonomies require change, specifying the subsequent stages involved in expanding CEMIS to all energy manpower, and providing the basis for cost estimates for this work. The report is organized as follows: The analytical rationale is described in Chapter II. Chapter III reviews the status of manpower data in a number of energy sectors, notes limitations and gaps in the data, and discusses improvements and additions that should be made. The scope and structure of CEMIS are laid out in Chapter IV, with particular reference to the development of analytical processes, and of analytical linking functions between bodies of data, and a description of their application in anticipating the employment impact of energy changes. The appropriate steps recommended for the further development of CEMIS are described in Chapter V.

  12. A new entropy model for RNA: part IV, The Minimum Free Energy (mFE and the thermodynamically most-probable folding pathway (TMPFP

    Directory of Open Access Journals (Sweden)

    Wayne Dawson

    2015-07-01

    Full Text Available Here we discuss four important questions (1 how can we be sure that the thermodynamically most-probable folding-pathway yields the minimum free energy for secondary structure using the dynamic programming algorithm (DPA approach, (2 what are its limitations, (3 how can we extend the DPA to find the minimum free energy with pseudoknots, and finally (4 what limitations can we expect to find in a DPA approach for pseudoknots. It is our supposition that some structures cannot be fit uniquely by the DPA, but may exist in real biology situations when disordered regions in the biomolecule are necessary. These regions would be identifiable by using suboptimal structure analysis. This grants us some qualitative tools to identify truly random RNA sequences, because such are likely to have greater degeneracy in their thermodynamically most-probable folding-pathway.

  5. Giant piezoelectricity of monolayer group IV monochalcogenides

    Science.gov (United States)

    Fei, Ruixiang; Li, Wenbin; Li, Ju; Yang, Li

    We predict enormous, anisotropic piezoelectric effects in intrinsic monolayer group IV monochalcogenides (MX, M =Sn or Ge, X =Se or S), including SnSe, SnS, GeSe, and GeS. Using first-principle simulations based on the modern theory of polarization, we find that their piezoelectric coefficients are about one to two orders of magnitude larger than those of other 2D materials, such as MoS2 and GaSe, and bulk quartz and AlN which are widely used in industry. This enhancement is a result of the unique ``puckered'' C2v symmetry and electronic structure of monolayer group IV monochalcogenides. Given the achieved experimental advances in the fabrication of monolayers, their flexible character, and ability to withstand enormous strain, these 2D structures with giant piezoelectric effects may be promising for a broad range of applications such as nano-sized sensors, piezotronics, and energy harvesting in portable electronic devices.

  6. System analysis using multitracer approaches. Chapter 9

    International Nuclear Information System (INIS)

    The present chapter offers a qualitative or semi-quantitative step towards a synthesis of the information that the different tracers provide. It also offers some criteria that can be used to help assess the reliability of selected tracer data in evaluating tracer model ages from measurements of concentrations of multiple environmental tracers in the system. In most of the literature on isotope hydrology, the term ‘apparent age’ is used instead of ‘tracer model age’, and within this chapter the two terms are considered synonymous. This approach testing reliability of tracer data is only a first step and performs a black and white selection of the tracer data. Some consistency tests are performed, and for data passing these tests there is at least no obvious reason known that the tracer model age is not a valid description. For data that fail these tests, it is obvious that a straightforward calculation of tracer model ages will not give the intended result.

  7. Measures of Image Quality. Chapter 4

    International Nuclear Information System (INIS)

    A medical image is a pictorial representation of a measurement of an object or function of the body. This information can be acquired in one to three spatial dimensions. It can be static or dynamic, meaning that it can also be measured as a function of time. Certain fundamental properties can be associated with all of these data. Firstly, no image can exactly represent the object or function; at best, one has a measurement with an associated error equal to the difference between the true object and the measured image. Secondly, no two images will be identical, even if acquired with the same imaging system of the same anatomic region; this variability is generally referred to as noise. There are many different ways to acquire medical image data; the various mechanisms of acquisition are described in detail in the subsequent chapters. However, regardless of the method of image formation, one must be able to judge the fidelity of the image in an attempt to answer the question “How accurately does the image portray the body or the bodily function?” This judgement falls under the rubric of ‘image quality’. In this chapter, methods of quantifying image quality are described

  8. Image Perception and Assessment. Chapter 18

    International Nuclear Information System (INIS)

    The main purpose of a medical image is to provide information to a human reader, such as a radiologist, so that a diagnosis can be reached — rather than to display the beauty of the human internal workings. It is important to understand how the human visual system affects the perception of contrast and spatial resolution of structures that are present in the image. If the image is not properly displayed, or the environment is not appropriate, subtle clinical signs may go unnoticed, which can potentially lead to a misdiagnosis. This chapter provides an introduction to human visual perception and task based objective assessment of an imaging system. A model for the contrast sensitivity of the human visual system is presented. This model is used to derive the greyscale standard display function for medical displays. Task based assessment measures the quality of an imaging system as the ability of an observer to perform a well defined task, based on a set of images. Metrics for observer performance are introduced, as well as experimental methodologies for the measurement of human performance. The last section of the chapter describes the estimation of task performance based on mathematical observer models

  10. Universal Sensor and Actuator Requirements. Chapter 5

    Rosenfeld, Taylor; Webster, John; Garg, Sanjay

    2009-01-01

    The previous chapters have focused on the requirements for sensors and actuators for "More Intelligent Gas Turbine Engines" from the perspective of performance and operating environment. Even if a technology is available, which meets these performance requirements, there are still various hurdles to be overcome for the technology to transition into a real engine. Such requirements relate to TRL (Technology Readiness Level), durability, reliability, volume, weight, cost, etc. This chapter provides an overview of such universal requirements which any sensor or actuator technology will have to meet before it can be implemented on a product. The objective here is to help educate the researchers or technology developers on the extensive process that the technology has to go through beyond just meeting performance requirements. The hope is that such knowledge will help the technology developers as well as decision makers to prevent wasteful investment in developing solutions to performance requirements, which have no potential to meet the "universal" requirements. These "universal" requirements can be divided into 2 broad areas: 1) Technology value proposition; and 2) Technology maturation. These requirements are briefly discussed in the following.

  14. Chapter 2: Stand-alone Applications - TOPCAT

    Science.gov (United States)

    Miller, C. J.

    Tool for OPerations on Catalogues And Tables or TOPCAT is a graphical viewer for table data. It offers a variety of ways to work with data tables, including a browser for the cell data, viewers for information about table and column metadata, dataset visualization, and even analysis. We discuss a small subset of TOPCAT's functionalities in this chapter. TOPCAT was originally developed as part of the Starlink program in the United Kingdom. It is now maintained by AstroGrid. The program is written in pure Java and available under the GNU General Public License. It is available for download and a version is included in the software distribution accompanying this book. TOPCAT is a GUI interface on top of the STIL library. A command line interface to this library, STILTS, described in Chapter 21 provides scriptable access to many of the capabilities described here. The purpose of this tutorial is to provide an overview of TOPCAT to the novice user. The best place to look for and learn about TOPCAT is the web page maintained by Mark B. Taylor. There, TOPCAT documentation is provided in HTML, PDF, via screen shots, etc. In this chapter we take the user through a few examples that give the general idea of how TOPCAT works. The majority of the functionality of TOPCAT is not included in this short tutorial. Our goal in this tutorial is to lead the reader through an exercise that would result in a publication quality figure (e.g. for a journal article). Specifically, we will use TOPCAT to show how the color-magnitude relation of a galaxy cluster compares to that of all galaxies in the Sloan Digital Sky Survey (York et al. 2000). This diagnostic is used not only in cluster finding, but its linear fit can provide insight into the age and/or metallicity of the oldest galaxies in galaxy clusters (which are some of the oldest galaxies in the Universe). The data we need for this exercise are: 1) the entire spectroscopic galaxy catalog from the SDSS, with galaxy positions, galaxy

  19. Semiconductor surface reactions studied with mass spectrometry and low energy ion scattering

    International Nuclear Information System (INIS)

    Ion bombardment initiated semiconductor surface reactions play a vital role in present device manufacturing technology. This thesis reports on etching studies of various materials using mass spectrometry and low energy ion scattering in an effort to learn more regarding the physical and chemical aspects of these systems. Chapter I reviews the current theories on ion/surface chemistry. An ultrahigh vacuum system was built to carry out the surface studies. Chapter II reports on the system design and characterization of the ion source and chamber, and reports a modulated beam technique developed to extract energy distributions of species leaving the surface. Chapter III presents mass spectrometric studies on the Si/Cl2/Ar+ system. SiCl and SiCl2 are the major chlorinated products generated from the ion induced reaction. These species are ejected from the surface with collision cascade energy distributions, in contrast to earlier proposals that a thermal mechanism dominated the reaction. Etching in the GaAs/Cl2/Ne+ system was found to proceed in a similar manner. These results are reported in Chapter IV. Etching of TaSi2 and TiSi2 in a chlorine environment suggests that anisotropic etch profiles of these materials can be obtained, as shown in Chapter V

  20. Chapter 40: history of neurology in France.

    Science.gov (United States)

    Clarac, François; Boller, François

    2010-01-01

    The history of neurology in France is characterized by the very high degree of centralization in that country where "everything seems to happen in Paris," and yet the considerable degree of autonomous diversity in the evolution of some other medical schools such as Montpellier and Strasbourg. It could be argued that France saw the birth of clinical neurology as a separate discipline since Jean Martin Charcot at the Salpêtrière Hospital obtained a chair of diseases of the nervous system in 1892, a first in the history of the academic world. The chapter shows, however, that the work of Charcot was preceded by a long evolution in medical thinking, which culminated with the introduction of experimental medicine developed by Claude Bernard and François Magendie, and by the study of aphasia by Paul Broca and its localization of language in a specific area of the brain. Many of the great neurologists of France like Duchenne de Boulogne, Gilles de la Tourette, Joseph Babinski and Pierre Marie gravitated around Charcot while others like Charles-Edward Brown-Sequard and Jules Dejerine developed their talents independently. The history of Sainte-Anne Hospital further illustrates this independence. It also shows the relation between neurology and psychiatry with Henri Ey, Jean Delay and Pierre Deniker, who collaborated with Henri Laborit in the clinical development of chlorpromazine. Sainte Anne also saw the birth of modern neuropsychology with Henry Hécaen. Jean Talairach and his group developed human stereotaxic neurosurgery and a 3-dimensional brain atlas that is used around the world. The chapter also mentions institutions (the CNRS and INSERM) that have contributed to developments partially independently from medical schools. It concludes with a presentation of schools located outside of Paris that have played a significant role in the development of neurology. Six of the most important ones are described: Montpellier, Toulouse, Bordeaux, Strasbourg, Lyon, and

  1. Mercury and halogens in coal: Chapter 2

    Science.gov (United States)

    Kolker, Allan; Quick, Jeffrey C.

    2014-01-01

    Apart from mercury itself, coal rank and halogen content are among the most important factors inherent in coal that determine the proportion of mercury captured by conventional controls during coal combustion. This chapter reviews how mercury in coal occurs, gives available concentration data for mercury in U.S. and international commercial coals, and provides an overview of the natural variation in halogens that influence mercury capture. Three databases, the U.S. Geological Survey coal quality (USGS COALQUAL) database for in-ground coals, and the 1999 and 2010 U.S. Environmental Protection Agency (EPA) Information Collection Request (ICR) databases for coals delivered to power stations, provide extensive results for mercury and other parameters that are compared in this chapter. In addition to the United States, detailed characterization of mercury is available on a nationwide basis for China, whose mean values in recent compilations are very similar to the United States in-ground mean of 0.17 ppm mercury. Available data for the next five largest producers (India, Australia, South Africa, the Russian Federation, and Indonesia) are more limited and with the possible exceptions of Australia and the Russian Federation, do not allow nationwide means for mercury in coal to be calculated. Chlorine in coal varies as a function of rank and correspondingly, depth of burial. As discussed elsewhere in this volume, on a proportional basis, bromine is more effective than chlorine in promoting mercury oxidation in flue gas and capture by conventional controls. The ratio of bromine to chlorine in coal is indicative of the proportion of halogens present in formation waters within a coal basin. This ratio is relatively constant except in coals that have interacted with deep-basin brines that have reached halite saturation, enriching residual fluids in bromine. Results presented here help optimize mercury capture by conventional controls and provide a starting point for

    The marine and hydrokinetic (MHK) environmental Impacts Knowledge Management System, dubbed “Tethys” after the mythical Greek titaness of the seas, is being developed by the Pacific Northwest National Laboratory (PNNL) to support the U.S. Department of Energy’s Wind and Water Power Program (WWPP). Functioning as a smart database, Tethys enables its users to identify key words or terms to help gather, organize and make available information and data pertaining to the environmental effects of MHK and offshore wind (OSW) energy development. By providing and categorizing relevant publications within a simple and searchable database, Tethys acts as a dissemination channel for information and data which can be utilized by regulators, project developers and researchers to minimize the environmental risks associated with offshore renewable energy developments and attempt to streamline the permitting process. Tethys also houses a separate content-related Annex IV data base with identical functionality to the Tethys knowledge base. Annex IV is a collaborative project among member nations of the International Energy Agency (IEA) Ocean Energy Systems – Implementing Agreement (OES-IA) that examines the environmental effects of ocean energy devices and projects. The U.S. Department of Energy leads the Annex IV working with federal partners such as the Federal Energy Regulatory Commission (FERC), the Bureau of Ocean Energy Management (BOEM), and the National Oceanic Atmospheric Administration (NOAA). While the Annex IV database contains technical reports and journal articles, it is primarily focused on the collection of project site and research study metadata forms (completed by MHK researchers and developers around the world, and collected by PNNL) which provide information on environmental studies and the current progress of the various international MHK developments in the Annex IV member nations. The purpose of this report is to provide a summary of the content

    Licht, B H; Shaw, K; Smith, C; Mendoza, M; Orr, J; Myers, D V

    1992-05-01

    A large number of commercial Caramel Colour IV samples were characterized in order to assess the uniformity of the class and to provide data to be used in specifications development. Owing to the chemical and physical complexity of caramel colour it was not feasible to perform detailed analysis of all constituents for assessment of uniformity. Instead, selected parameters were evaluated and judgements were made with respect to compositional uniformity based on the similarities of these parameters among the various samples. As Caramel Colour IV is required by the food industry in a range of colour intensities, there must be a range of properties that differ from sample to sample, but that are sufficiently similar for the material to still be considered as part of the Caramel Colour IV class. Fractions as well as whole caramel were analysed using selected spectrophotometric, chromatographic and chemical techniques. Samples were fractionated based on molecular weight and polarity. The data presented here provide evidence for the uniformity in composition of Caramel Colour IV with respect to molecular weight distribution, to nitrogen and sulphur content and their distribution throughout the fractions, to absorbance properties and to specific low molecular weight compounds. Thus, it can be concluded that Caramel Colour IV exhibits compositional uniformity within the range of colour intensity required by the food industry worldwide. PMID:1644377

  11. Chapter 24: Programmatic Interfaces - IDL VOlib

    Science.gov (United States)

    Miller, C. J.

    In this chapter, we describe a library for working with the VO using IDL (the Interactive Data Language). IDL is a software environment for data analysis, visualization, and cross-platform application development. It has wide-usage in astronomy, including NASA (e.g. http://seadas.gsfc.nasa.gov/), the Sloan Digital Sky Survey (http://www.sdss.org), and the Spitzer Infrared Spectrograph Instrument (http://ssc.spitzer.caltech.edu/archanaly/contributed/smart/). David Stern, the founder of Research Systems, Inc. (RSI), began the development of IDL while working with NASA's Mars Mariner 7 and 9 data at the Laboratory for Atmospheric and Space Physics at the University of Colorado. In 1981, IDL was rewritten in assembly language and FORTRAN for VAX/VMS. IDL's usage has expanded over the last decade into the fields of medical imaging and engineering, among many others. IDL's programming style carries over much of this FORTRAN-legacy, and has a familiar feel to many astronomers who learned their trade using FORTRAN. The spread of IDL-usage amongst astronomers can in part be attributed to the wealth of publicly astronomical libraries. The Goddard Space Flight Center (GSFC) maintains a list of astronomy-related IDL libraries, including the well known Astronomy User's Library (hereafter ASTROLIB2). We will use some of these GSFC IDL libraries. We note that while IDL is a licensed-software product, the source code of user-written procedures are typically freely available to the community. To make the most out of this section as a reader, it is important that many of the data discovery, access, and analysis protocols are understood before reading this chapter. In the next section, we provide an overview of some of the NVO terminology with which the reader should be familiar. The IDL library discussed here is specifically for use with the Virtual Observatory and is named VOlib. IDL's VOlib is available at http://nvo.noao.edu and is included with the software distrubution for this

  12. Chapter 19: HVAC Controls (DDC/EMS/BAS) Evaluation Protocol

    Energy Technology Data Exchange (ETDEWEB)

    Romberger, J.

    2014-11-01

    The HVAC Controls Evaluation Protocol is designed to address evaluation issues for direct digital controls/energy management systems/building automation systems (DDC/EMS/BAS) that are installed to control heating, ventilation, and air-conditioning (HVAC) equipment in commercial and institutional buildings. (This chapter refers to the DDC/EMS/BAS measure as HVAC controls.) This protocol may also be applicable to industrial facilities such as clean rooms and labs, which have either significant HVAC equipment or spaces requiring special environmental conditions. This protocol addresses only HVAC-related equipment and the energy savings estimation methods associated with installing such control systems as an energy efficiency measure. The affected equipment includes: Air-side equipment (air handlers, direct expansion systems, furnaces, other heating- and cooling-related devices, terminal air distribution equipment, and fans); Central plant equipment (chillers, cooling towers, boilers, and pumps). These controls may also operate or affect other end uses, such as lighting, domestic hot water, irrigation systems, and life safety systems such as fire alarms and other security systems. Considerable nonenergy benefits, such as maintenance scheduling, system component troubleshooting, equipment failure alarms, and increased equipment lifetime, may also be associated with these systems. When connected to building utility meters, these systems can also be valuable demand-limiting control tools. However, this protocol does not evaluate any of these additional capabilities and benefits.

  13. Generation IV and the ELSY Project

    International Nuclear Information System (INIS)

    This is a PowerPoint presentation addressing the subject of Generation IV reactors and the ELSY Project. A short sketch of the evolution of nuclear power is presented beginning from 1950 with early reactors, through current commercial reactors and continuing with projection of advanced reactors and future systems till 2090. Arguments for Generation IV are based on energy resource availability, climate change, air quality, and energy security, which all suggest an important role for nuclear power in future energy supplies. While the current Generation II and III nuclear power plant designs provide a secure and low-cost electricity supply in many markets, further advances in nuclear energy system design can broaden the opportunities for the use of nuclear energy. To explore these opportunities, the U.S. Department of Energy's Office of Nuclear Energy, Science and Technology has engaged governments, industry, and the research community worldwide in a wide ranging discussion on the development of next generation nuclear energy systems known as Generation IV. As basic criteria of selection, focussed are: Sustainability, Economics, Safety and Reliability, Proliferation Resistance and Physical Protection. In January 2000 the Generation IV International Forum (GIF) was established to investigate innovative nuclear energy system concepts for meeting future energy challenges. Purpose of GIF is to coordinate international research and development on promising new nuclear energy systems for meeting future energy challenges. With international collaboration, approximately 100 system concepts were analyzed and evaluated for their potential to meet the goals of the Generation IV program. The selection of systems for cooperative development by GIF was based on the evaluations of each system's ability to fulfill targeted applications, deployment readiness, and development cost. Generation IV Road Map published by GIF in December 2002, selected the following six systems and

There is now more evidence and more agreement among climate scientists about the physical climate and related impacts in the Southwest compared with that represented in the 2009 National Climate Assessment (Karl, Melillo, and Peterson 2009). However, there remain uncertainties about the climate system, the complexities within climate models, the related impacts to the biophysical environment, and the use of climate information on decision making. Uncertainty is introduced in each step of the climate planning-an-response process--in the scenarios used to drive the climate models, the information used to construct the models, and the interpretation and use of the model' data for planning and decision making (Figure 19.1). There are server key challenge, drawn from recommendations of the authors of this report, that contribute to these uncertainties in the Southwest: - There is a dearth of climate observations at high elevations and on the lands of Native nations.

  18. Generation IV reactors: economics

    International Nuclear Information System (INIS)

    The operating nuclear reactors were built over a short period: no more than 10 years and today their average age rounds 18 years. EDF (French electricity company) plans to renew its reactor park over a far longer period : 30 years from 2020 to 2050. According to EDF this objective implies 3 constraints: 1) a service life of 50 to 60 years for a significant part of the present operating reactors, 2) to be ready to built a generation 3+ unit in 2020 which infers the third constraint: 3) to launch the construction of an EPR (European pressurized reactor) prototype as soon as possible in order to have it operating in 2010. In this scheme, generation 4 reactor will benefit the feedback experience of generation 3 and will take over in 2030. Economic analysis is an important tool that has been used by the generation 4 international forum to select the likely future reactor systems. This analysis is based on 4 independent criteria: the basic construction cost, the construction time, the operation and maintenance costs and the fuel cycle cost. This analysis leads to the evaluation of the global cost of electricity generation and of the total investment required for each of the reactor system. The former defines the economic competitiveness in a de-regulated energy market while the latter is linked to the financial risk taken by the investor. It appears, within the limits of the assumptions and models used, that generation 4 reactors will be characterized by a better competitiveness and an equivalent financial risk when compared with the previous generation.

    Full Text Available The present article describes a chemical and physical study of the colour, chemical composition and mineral phases of the decorative materials in the Seville City Hall Chapter House ceiling. The findings showed that the inner most layer of material, calcite, was covered with white lead, in turn concealed under a layer of gilded bole. The ceiling underwent re-gilding, also over bole, due in all likelihood to wear on the original gold leaf. In the nineteenth century, the entire ceiling with the exception of the inscriptions was whitewashed with calcite and white lead. Silver was employed on King John I’s sword (coffer 27. Gold leaf was used to adorn the royal attributes: crowns, belts, sceptres, swords and rosary beads. The high reliefs were likewise gilded. The pigments identified on the ceiling adornments included azurite, malachite, vermilion and gas black. A lime and ground dolomite mortar was used throughout.

    El objetivo de este trabajo es el estudio de diferentes aspectos, como el color, la composición química y las fases mineralógicas presentes en los diferentes materiales que forman la ornamentación del techo de la Sala Capitular del Ayuntamiento de Sevilla, mediante métodos físicos y químicos. Nuestros resultados muestran que el dorado fue realizado sobre una capa de bol previamente depositada sobre una lámina de blanco de plomo que cubría un estrato de calcita. Posteriormente, y probablemente debido a alteraciones en el dorado original, el techo fue de nuevo dorado usando una técnica similar. En el siglo XIX, casi todo el techo, excepto las zonas con inscripciones, fue blanqueado usando una mezcla de calcita y blanco de plomo. Se empleó plata para cubrir la espada del rey Juan I (casetón 27. Finísimas láminas de oro se usaron para decorar los atributos reales: coronas, cinturones, cetros, espadas y rosarios. En diferentes partes de la decoración fueron detectados pigmentos como azurita, malaquita, bermellón y

  6. Chapter 15 Juvenile amyotrophic lateral sclerosis.

    Science.gov (United States)

    Orban, Paul; Devon, Rebecca S; Hayden, Michael R; Leavitt, Blair R

    2007-01-01

    Several forms of genetically defined juvenile amy-otrophic lateral sclerosis (ALS) have now been charac-terized and discussion of these conditions will form the basis for this chapter. ALS2 is an autosomal recessive form of ALS with a juvenile onset and very slow progression that mapped to chromosome 2q33. Nine different mutations have been identified in the ALS2 gene that result in premature stop codons, suggesting a loss of function in the gene product, alsin. The alsin protein is thought to function as a guanine-nucleotide exchange factor for GTPases and may play a role in vesicle transport or membrane trafficking processes. ALS4 is an autosomal dominant form of juvenile onset ALS associated with slow progression, severe muscle weakness and pyramidal signs, in the absence of bulbar and sensory abnormalities. Mutations in the SETX gene cause ALS4, and the SETX gene product senataxin may have DNA and RNA helicase activity and play a role in the regulation of RNA and/or DNA in the cell. A third form of juvenile-onset ALS (ALS5) is associated with slowly progressing lower motor neuron signs (weak-ness and atrophy) initially of the hands and feet, with eventual bulbar involvement. Progressive upper motor neuron disease becomes more obvious with time. ALS5 has been linked to a 6 cM region of chromosome 15q15.1-q21.1, but the causative gene mutation for ALS5 has yet to be identified. The high degree of clin-ical and genetic heterogeneity in the various forms of juvenile ALS can make differential diagnosis difficult, other genetic disorders that must be considered include: spinal muscular atrophy, hereditary spastic paraplegia, SBMA, GM2 gangliosidosis and the hereditary motor neuronopathies/motor forms of Charcot-Marie-Tooth disease. Acquired disorders that must also be consid-ered include heavy metal intoxications (especially lead), multifocal motor neuropathy, paraneoplastic syndromes, vitamin deficiencies (B12) and infections (HTLV-II, HIV and poliomyelitis).

    The main role of carbohydrates in the human body is to provide energy. Carbohydrates should always be infused with PN (parenteral nutrition) in combination with amino acids and lipid emulsions to improve nitrogen balance. Glucose should be provided as a standard carbohydrate for PN, whereas the use of xylite is not generally recommended. Fructose solutions should not be used for PN. Approximately 60% of non-protein energy should be supplied as glucose with an intake of 3.0-3.5 g/kg body weigh...

  13. The MAX IV storage ring project

    International Nuclear Information System (INIS)

    The design of the MAX IV 3 GeV ultralow-emittance storage ring is presented and the implementation of solutions to the technological challenges imposed by the compact multi-bend achromat lattice are described. The MAX IV facility, currently under construction in Lund, Sweden, features two electron storage rings operated at 3 GeV and 1.5 GeV and optimized for the hard X-ray and soft X-ray/VUV spectral ranges, respectively. A 3 GeV linear accelerator serves as a full-energy injector into both rings as well as a driver for a short-pulse facility, in which undulators produce X-ray pulses as short as 100 fs. The 3 GeV ring employs a multibend achromat (MBA) lattice to achieve, in a relatively short circumference of 528 m, a bare lattice emittance of 0.33 nm rad, which reduces to 0.2 nm rad as insertion devices are added. The engineering implementation of the MBA lattice raises several technological problems. The large number of strong magnets per achromat calls for a compact design featuring small-gap combined-function magnets grouped into cells and sharing a common iron yoke. The small apertures lead to a low-conductance vacuum chamber design that relies on the chamber itself as a distributed copper absorber for the heat deposited by synchrotron radiation, while non-evaporable getter (NEG) coating provides for reduced photodesorption yields and distributed pumping. Finally, a low main frequency (100 MHz) is chosen for the RF system yielding long bunches, which are further elongated by passively operated third-harmonic Landau cavities, thus alleviating collective effects, both coherent (e.g. resistive wall instabilities) and incoherent (intrabeam scattering). In this paper, we focus on the MAX IV 3 GeV ring and present the lattice design as well as the engineering solutions to the challenges inherent to such a design. As the first realisation of a light source based on the MBA concept, the MAX IV 3 GeV ring offers an opportunity for validation of concepts that are

    Keates, S.

    2014-09-01

    This protocol is intended to describe the recommended method when evaluating the whole-building performance of new construction projects in the commercial sector. The protocol focuses on energy conservation measures (ECMs) measures (or packages of measures) where evaluators can best analyze impacts using building simulation. These ECMs typically require the use of calibrated building simulations under Option D of the International Performance Measurement and Verification Protocol. Examples of such measures include Leadership in Energy and Environmental Design building certification, novel and/or efficient heating, ventilation, and air conditioning system designs, and extensive building controls systems. In general, it is best to evaluate any ECM (or set of measures) expected to significantly interact with other systems within the building and with savings sensitive to seasonal variations in weather.

  8. Chapter 20: Data Center IT Efficiency Measures

    Energy Technology Data Exchange (ETDEWEB)

    Huang, R.; Masanet, E.

    2015-01-01

    Data centers use about 2% of the electricity in the United States; a typical data center has 100 to 200 times the energy use intensity of a commercial building. Data centers present tremendous opportunities--energy use can be reduced as much as 80% between inefficient and efficient data centers. Data center efficiency measures generally fall into the following categories: power infrastructure (e.g., more efficient uninterruptible power supplies, power distribution units); cooling (e.g., free cooling, variable-speed drives, temperature and humidity set points); airflow management (e.g., hot aisle/cold aisle, containment, grommets); and information technology efficiency (e.g., server virtualization, efficient servers, efficient data storage).

  9. Chapter 22: Compressed Air Evaluation Protocol

    Benton, N.

    2014-11-01

    Compressed-air systems are used widely throughout industry for many operations, including pneumatic tools, packaging and automation equipment, conveyors, and other industrial process operations. Compressed-air systems are defined as a group of subsystems composed of air compressors, air treatment equipment, controls, piping, pneumatic tools, pneumatically powered machinery, and process applications using compressed air. A compressed-air system has three primary functional subsystems: supply, distribution, and demand. Air compressors are the primary energy consumers in a compressed-air system and are the primary focus of this protocol. The two compressed-air energy efficiency measures specifically addressed in this protocol are: high-efficiency/variable speed drive (VSD) compressor replacing modulating compressor; compressed-air leak survey and repairs. This protocol provides direction on how to reliably verify savings from these two measures using a consistent approach for each.

    Upgraded electronics, improved water system dynamics, better calibration and analysis techniques allowed Super-Kamiokande-IV to clearly observe very low-energy 8B solar neutrino interactions, with recoil electron kinetic energies as low as 3.49 MeV. Super-Kamiokande-IV data-taking began in September of 2008; this paper includes data until February 2014, a total livetime of 1664 days. The measured solar neutrino flux is (2.308+-0.020(stat.) + 0.039-0.040(syst.)) x 106/(cm2sec) assuming no oscillations. The observed recoil electron energy spectrum is consistent with no distortions due to neutrino oscillations. An extended maximum likelihood fit to the amplitude of the expected solar zenith angle variation of the neutrino-electron elastic scattering rate in SK-IV results in a day/night asymmetry of (-3.6+-1.6(stat.)+-0.6(syst.))%. The SK-IV solar neutrino data determine the solar mixing angle as sin2 theta_12 = 0.327+0.026-0.031, all SK solar data (SK-I, SK-II, SK III and SKIV) measures this angle to be sin2 the...

  12. Structure and luminescent properties of complex compounds of tellurium(IV) with ammonium bases

    Science.gov (United States)

    Sedakova, T. V.; Mirochnik, A. G.

    2015-07-01

    Using tellurium(IV) complex compounds with outer-sphere ammonium cations as an example, we have studied the interrelation between their geometric structure and spectral-luminescent properties. In the series of compounds of tellurium(IV), which are characterized by the island octahedral coordination of Te(IV) ions, the luminescence intensity has been found to depend on the degree of distortion of the coordination polyhedron of the Te(IV) ion, the position of the A band in diffuse reflection spectra, and the energy of the luminescence transition 3 P 1 → 1 S 0 of the tellurium(IV) ion. We have revealed that the considered Te(IV) complexes possess reversible thermochromic properties.

  3. Statistics for Radiation Measurement. Chapter 5

    International Nuclear Information System (INIS)

    Measurement errors are of three general types: (i) blunders, (ii) systematic errors or accuracy of measurements, and (iii) random errors or precision of measurements. Blunders produce grossly inaccurate results and experienced observers easily detect their occurrence. Examples in radiation counting or measurements include the incorrect setting of the energy window, counting heavily contaminated samples, using contaminated detectors for imaging or counting, obtaining measurements of high activities, resulting in count rates that lead to excessive dead time effects, and selecting the wrong patient orientation during imaging. Although some blunders can be detected as outliers or by duplicate samples and measurements, blunders should be avoided by careful, meticulous and dedicated work. This is especially important where results will determine the diagnosis or treatment of patients

  4. Bioenergetics modeling of percid fishes: Chapter 14

    Science.gov (United States)

    Madenjian, Charles P.

    2015-01-01

    A bioenergetics model for a percid fish represents a quantitative description of the fish’s energy budget. Bioenergetics modeling can be used to identify the important factors determining growth of percids in lakes, rivers, or seas. For example, bioenergetics modeling applied to yellow perch (Perca flavescens) in the western and central basins of Lake Erie revealed that the slower growth in the western basin was attributable to limitations in suitably sized prey in western Lake Erie, rather than differences in water temperature between the two basins. Bioenergetics modeling can also be applied to a percid population to estimate the amount of food being annually consumed by the percid population. For example, bioenergetics modeling applied to the walleye (Sander vitreus) population in Lake Erie has provided fishery managers valuable insights into changes in the population’s predatory demand over time. In addition, bioenergetics modeling has been used to quantify the effect of the difference in growth between the sexes on contaminant accumulation in walleye. Field and laboratory evaluations of percid bioenergetics model performance have documented a systematic bias, such that the models overestimate consumption at low feeding rates but underestimate consumption at high feeding rates. However, more recent studies have shown that this systematic bias was due, at least in part, to an error in the energy budget balancing algorithm used in the computer software. Future research work is needed to more thoroughly assess the field and laboratory performance of percid bioenergetics models and to quantify differences in activity and standard metabolic rate between the sexes of mature percids.

  5. World oil prices: prospects and implications for energy policy-makers in Latin America's oil-deficit countries

    Energy Technology Data Exchange (ETDEWEB)

    Mullen, J.W.

    1978-01-01

    This study considers two broad topics: future prices for world crude oil and energy policy in Latin American oil-deficit countries. Chapter I identifies and explains the pattern of world crude oil prices in the post-war era. Chapter II provides an analysis of the structure of today's world crude oil market from the point of view of price formation. Chapter III discusses the current pattern of energy policies in the industrialized, oil-importing countries. Again, the emphasis is on price formation. Chapter IV focuses on the price forecast. It opens with an estimate of the maximum level of the long-run incremental cost of supplying world oil over the next two decades. Chapter V deals with the range of options open to policy-makers in Latin America's oil-deficit countries as they confront the expected price of world crude oil. It closes with a discussion of the security of oil imports in Latin America's oil-deficit countries.

  8. The Physiology of Bed Rest. Chapter 39

    Science.gov (United States)

    Fortney, Suzanne M.; Schneider, Victor S.; Greenleaf, John E.

    1996-01-01

    Prolonged rest in bed has been utilized by physicians and other health-care workers to immobilize and confine patients for rehabilitation and restoration of health since time immemorial. The sitting or horizontal position is sought by the body to relieve the strain of the upright or vertical postures, for example during syncopal situations, bone fractures, muscle injuries, fatigue, and probably also to reduce energy expenditure. Most health-care personnel are aware that adaptive responses occurring during bed rest proceed concomitantly with the healing process; signs and symptoms associated with the former should be differentiated from those of the latter. Not all illnesses and infirmities benefit from prolonged bed rest. Considerations in prescribing bed rest for patients-including duration, body position, mode and duration of exercise, light-dark cycles, temperature, and humidity-have not been investigated adequately. More recently, adaptive physiological responses have been measured in normal, healthy subjects in the horizontal or slightly head-down postures during prolonged bed rest as analogs for the adaptive responses of astronauts exposed to the microgravity environment of outer and bed-rest research.

  9. Chapter 18: Variable Frequency Drive Evaluation Protocol

    Energy Technology Data Exchange (ETDEWEB)

    Romberger, J.

    2014-11-01

    An adjustable-speed drive (ASD) includes all devices that vary the speed of a rotating load, including those that vary the motor speed and linkage devices that allow constant motor speed while varying the load speed. The Variable Frequency Drive Evaluation Protocol presented here addresses evaluation issues for variable-frequency drives (VFDs) installed on commercial and industrial motor-driven centrifugal fans and pumps for which torque varies with speed. Constant torque load applications, such as those for positive displacement pumps, are not covered by this protocol. Other ASD devices, such as magnetic drive, eddy current drives, variable belt sheave drives, or direct current motor variable voltage drives, are also not addressed. The VFD is by far the most common type of ASD hardware. With VFD speed control on a centrifugal fan or pump motor, energy use follows the affinity laws, which state that the motor electricity demand is a cubic relationship to speed under ideal conditions. Therefore, if the motor runs at 75% speed, the motor demand will ideally be reduced to 42% of full load power; however, with other losses it is about 49% of full load power.

    2012-11-01

    The Indian Vacuum Society (IVS) was established in 1970 to promote vacuum science and technology in academic, industrial and R&D institutions in India. IVS is a member society of the International Union for Vacuum Science, Technique and Applications (IUVSTA). It has organized International and national symposia, short term courses and workshops on different aspects of Vacuum Science and Technology at regular intervals. So far 27 National symposia, 4 International Symposia and 47 courses have been organized at various locations in India. There has been an active participation from R&D establishments, universities and Indian industries during all these events. In view of the current global situation and emerging trends in vacuum technology, the executive committee of the IVS suggested to us that we organize an International Symposium at the Variable Energy Cyclotron Centre, Kolkata from 15-17 February 2012. At the Variable Energy Cyclotron Centre we have a large number of high vacuum systems used in the K130 Cyclotron and K500 Superconducting Cyclotron. Also a large cryogenic system using LHe plant is in operation for cryopanels and a superconducting magnet for K-500 Cyclotron. The main areas covered at the symposium were the production and measurement of vacuums, leak detection, design and development of large vacuum systems, vacuum metallurgy, vacuum materials and the application of high vacuums in cyclotrons, LINACS and other accelerators. This symposium provided an opportunity for interaction between active researchers and technologists and allowed them to review the current situation, report recent experimental results, share the available expertise and consider the future R&D efforts needed in this area. Keeping the industrial significance of vacuum technology in mind, an exhibition of the vacuum related equipment, accessories, products etc by various suppliers and manufactures was organized alongside the symposium. Participation by a large number of exhibitors

    2016-07-01

    Every few years the International Terrestrial Reference System (ITRS) Center of the International Earth Rotation and Reference Systems Service (IERS) decides to generate a new version of the International Terrestrial Reference Frame (ITRF). For the upcoming ITRF2014 the official contribution of the International VLBI Service for Geodesy and Astrometry (IVS) comprises 5796 combined sessions in SINEX file format from 1979.6 to 2015.0 containing 158 stations, overall. Nine AC contributions were included in the combination process, using five different software packages. Station coordinate time series of the combined solution show an overall repeatability of 3.3 mm for the north, 4.3 mm for the east and 7.5 mm for the height component over all stations. The minimum repeatabilities are 1.5 mm for north, 2.1 mm for east and 2.9 mm for height. One of the important differences between the IVS contribution to the ITRF2014 and the routine IVS combination is the omission of the correction for non-tidal atmospheric pressure loading (NTAL). Comparisons between the amplitudes of the annual signals derived by the VLBI observations and the annual signals from an NTAL model show that for some stations, NTAL has a high impact on station height variation. For other stations, the effect of NTAL is low. Occasionally other loading effects have a higher influence (e.g. continental water storage loading). External comparisons of the scale parameter between the VTRF2014 (a TRF based on combined VLBI solutions), DTRF2008 (DGFI-TUM realization of ITRS) and ITRF2008 revealed a significant difference in the scale. A scale difference of 0.11 ppb (i.e. 0.7 mm on the Earth's surface) has been detected between the VTRF2014 and the DTRF2008, and a scale difference of 0.44 ppb (i.e. 2.8 mm on the Earth's surface) between the VTRF2014 and ITRF2008. Internal comparisons between the EOP of the combined solution and the individual solutions from the AC contributions show a WRMS in X- and Y-Pole between

  18. Physics of Magnetic Resonance. Chapter 14

    The discovery of nuclear magnetic resonance (NMR), a property of nuclei in a magnetic field where they are able to absorb applied radiofrequency (RF) energy and subsequently release it at a specific frequency, goes back many decades to the early 1900s. Physicist Isidor I. Rabi, fascinated by the work of Otto Stern and Walther Gerlach which demonstrated that particles have intrinsic quantum properties, delved into the magnetic properties of nuclei, and in 1938 Rabi discovered the phenomenon of NMR. Several years later, in 1946, Felix Bloch and Edward Purcell refined the methods and successfully measured the NMR signal from liquids and solids. For their discoveries, Rabi received the Nobel Prize for physics in 1944 and Bloch and Purcell in 1952. While Rabi, Bloch, Purcell and other physicists working in this field had laid the foundations, a major discovery that transformed the NMR phenomenon for imaging was not made until 1973, when Paul Lauterbur developed a method for spatially encoding the NMR signal by utilizing linear magnetic field gradients. About the same time, Peter Mansfield had also discovered a means of determining the spatial structure of solids by introducing a linear gradient across the object. The idea of applying magnetic field gradients to induce spatially varying resonance frequencies to resolve the spatial distribution of magnetization was a major milestone and the beginning of magnetic resonance imaging (MRI). For their work, Lauterbur and Mansfield were awarded the Nobel Prize for medicine in 2003. Since its discovery, MRI has quickly become one of the most important medical imaging devices available to physicians today. Unlike other imaging modalities, such as X ray and computed tomography, MRI does not involve ionizing radiation. MRI also offers superior soft tissue contrast that is not possible with other imaging modalities. Furthermore, in MRI, the desired level of image contrast among different tissues can often be precisely controlled

    This paper presents the electro-regeneration of Ce(IV) in real (hazardous) spent thin-film transistor liquid-crystal display (TFT-LCD) Cr-etching solutions. In addition to Ce(III)>Ce(IV) in diffusivity, a quasi-reversible behavior of Ce(III)/Ce(IV) was observed at both boron-doped diamond (BDD) and Pt disk electrodes. The Ce(IV) yield on Pt increased with increasing current density, and the best current efficiency (CE) was obtained at 2A/2.25 cm(2). The performance in terms of Ce(IV) yield and CE of tested anodes was in order BDD>Pt>dimensional stable anode (DSA). At 2A/2.25 cm(2) on Pt and 40 °C for 90 min, the Ce(IV) yield, CE and apparent rate constant (k) for Ce(III) oxidation were 81.4%, 21.8% and 3.17 × 10(-4) s(-1), respectively. With the increase of temperature, the Ce(IV) yield, CE, and k increased (activation energy = 10.7 kJ/mol), but the specific electricity consumption decreased. The Neosepta CMX membrane was more suitable than Nafion-117 and Nafion-212 to be used as the separator of the Ce(IV) regeneration process. The obtained parameters are useful to design divided batch reactors for the Ce(IV) electro-regeneration in real spent Cr-etching solutions. PMID:24140527

  18. Policy-induced market introduction of Generation IV reactor systems

    International Nuclear Information System (INIS)

    Almost 10 years ago the U.S. Department of Energy (DOE) started the Generation IV Initiative (GenIV) with 9 other national governments with a positive ground attitude towards nuclear energy. Some of these Generation IV systems, like the fast reactors, are nearing the demonstration stage. The question on how their market introduction will be implemented becomes increasingly urgent. One main topic for future reactor technologies is the treatment of radioactive waste products. Technological solutions to this issue are being developed. One possible process is the transformation of long-living radioactive nuclides into short living ones; a process known as transmutation, which can be done in a nuclear reactor only. Various Generation IV reactor concepts are suitable for this process, and of these systems most experience has been gained with the sodium-cooled fast reactor (SFR). However, both these first generation SFR plants and their Generation IV successors are designed as electricity generating plants, and therefore supposed to be commercially viable in the electricity markets. Various studies indicate that the generation costs of a combined LWR-(S)FR nuclear generating park (LWR: light water reactor) will be higher than that of an LWR-only park. To investigate the effects of the deployment of the different reactors and fuel cycles on the waste produced, resources used and costs incurred as a function of time, a dynamic fuel cycle assessment is performed. This study will focus on the waste impact of the introduction of a fraction of fast reactors in the European nuclear reactor park with a cost increase as described in the previous paragraph. The nuclear fuel cycle scenario code DANESS is used for this, as well as the nuclear park model of the EU-27 used for the previous study. (orig.)

  19. Resolution of type IV singularities in quantum cosmology

    International Nuclear Information System (INIS)

    We discuss the fate of classical type IV singularities in quantum cosmology. As a framework we use Wheeler-DeWitt quantization applied to a homogeneous and isotropic universe with a perfect fluid described by a generalized Chaplygin gas. Such a fluid can be dynamically realized by a scalar field. We treat the cases of a standard scalar field with positive kinetic energy and of a scalar field with negative energy (phantom field). We are able to solve the Wheeler-DeWitt equation for these models analytically for a special case and to draw conclusions for the general case. Adopting the criterion that singularities are avoided if the wave function vanishes in the region of the classical singularity, we find that type IV singularities are avoided only for particular solutions of the Wheeler-DeWitt equation. We compare this result with earlier results found for other types of singularities.

    2009-04-20

    The most common method of analysis for beryllium is inductively coupled plasma atomic emission spectrometry (ICP-AES). This method, along with inductively coupled plasma mass spectrometry (ICP-MS), is discussed in Chapter 6. However, other methods exist and have been used for different applications. These methods include spectroscopic, chromatographic, colorimetric, and electrochemical. This chapter provides an overview of beryllium analysis methods other than plasma spectrometry (inductively coupled plasma atomic emission spectrometry or mass spectrometry). The basic methods, detection limits and interferences are described. Specific applications from the literature are also presented.

  5. The petrochemical industry and its energy use. Prospects for the Dutch energy intensive industry

    International Nuclear Information System (INIS)

    The current state and the future of the Dutch petrochemical industry are discussed. First, its current energy use, technology and its markets are analysed. Competitiveness of Dutch and Western European producers compared to foreign producers is shown. Main technological developments and other key issues (e.g. environmental issues) are discussed. Based on this analysis, a future scenario is derived for petrochemical industrial energy use for the period 2000-2015. This case study can be divided into an analysis of the current situation (Chapter 2-6) and alternatives for production and energy consumption of the Dutch petrochemical industry within its Western European context (Chapter 7-11). Chapter 2 analyses the current production structure and the historical developments. Chapter 3 discusses current technologies. Chapter 4 analyses markets for Dutch petrochemical products. Chapter 5 analyses the industry economics in the Netherlands in terms of costs and revenues. Chapter 6 provides information on institutional factors that influence industrial activities. Chapter 7 discusses global competition with special emphasis on competition for the European market. Chapter 8 analyses potential technology shifts. In Chapter 9, data from the preceding chapters on markets, competition, structure and technology are combined to compare competing production options. This is followed by a sensitivity analysis in Chapter 10. Based on a production volume forecast and the development of energy intensity of production, energy consumption of the Dutch petrochemical industry is forecast in Chapter 11. Finally, Chapter 12 provides conclusions and policy recommendations. 24 figs., 48 tabs., 103 refs., 2 appendices

    Full Text Available Protein catabolism should be reduced and protein synthesis promoted with parenteral nutrion (PN. Amino acid (AA solutions should always be infused with PN. Standard AA solutions are generally used, whereas specially adapted AA solutions may be required in certain conditions such as severe disorders of AA utilisation or in inborn errors of AA metabolism. An AA intake of 0.8 g/kg/day is generally recommended for adult patients with a normal metabolism, which may be increased to 1.2–1.5 g/kg/day, or to 2.0 or 2.5 g/kg/day in exceptional cases. Sufficient non-nitrogen energy sources should be added in order to assure adequate utilisation of AA. A nitrogen calorie ratio of 1:130 to 1:170 (g N/kcal or 1:21 to 1:27 (g AA/kcal is recommended under normal metabolic conditions. In critically ill patients glutamine should be administered parenterally if indicated in the form of peptides, for example 0.3–0.4 g glutamine dipeptide/kg body weight/day (=0.2–0.26 g glutamine/kg body weight/day. No recommendation can be made for glutamine supplementation in PN for patients with acute pancreatitis or after bone marrow transplantation (BMT, and in newborns. The application of arginine is currently not warranted as a supplement in PN in adults. N-acetyl AA are only of limited use as alternative AA sources. There is currently no indication for use of AA solutions with an increased content of glycine, branched-chain AAs (BCAA and ornithine-α-ketoglutarate (OKG in all patients receiving PN. AA solutions with an increased proportion of BCAA are recommended in the treatment of hepatic encephalopathy (III–IV.

  10. KENO IV: an improved Monte Carlo criticality program

    International Nuclear Information System (INIS)

    KENO IV is a multigroup Monte Carlo criticality program written for the IBM 360 computers. It executes rapidly and is flexibly dimensioned so the allowed size of a problem (i.e., the number of energy groups, number of geometry cards, etc., are arbitrary) is limited only by the total data storage required. The input data, with the exception of cross sections, fission spectra and albedos, may be entered in free form. The geometry input is quite simple to prepare and complicated three-dimensional systems can often be described with a minimum of effort. The results calculated by KENO IV include k-effective, lifetime and generation time, energy-dependent leakages and absorptions, energy- and region-dependent fluxes and region-dependent fission densities. Criticality searches can be made on unit dimensions or on the number of units in an array. A summary of the theory utilized by KENO IV, a section describing the logical program flow, a compilation of the error messages printed by the code and a comprehensive data guide for preparing input to the code are presented. 14 references

  11. The generation IV international research programme. The UK contribution

    International Nuclear Information System (INIS)

    The UK has been a member of the International Generation-IV Initiative since its inception in 2000. Principal amongst the UK's interest are the retention and development of the skills and capabilities necessary to support the selection, licensing, operation, and waste management associated with the possible future deployment of new nuclear energy systems, in order to retain nuclear power as a future energy option for the UK. There is a long and distinguished history of nuclear energy development in the UK, and organizations such as Nexia Solutions, AMEC-NNC, and Serco Assurance retain many capabilities and facilities which can be deployed in support of the development of Generation-IV technologies. The UK has particularly strong capabilities in the fields of gas-cooled systems and fast reactor technology, and this has influenced the selection of Generation-IV systems of greatest interest to the UK: namely, the Very High Temperature Reactor (VHTR), the Gas-cooled Fast Reactor (GFR), and the Sodium Fast Reactor (SFR). Similarly, the county's strengths in fuel and fuel cycle technology and in materials science have shaped the contribution planned for the Feasibility Phase of the GIF programme. Examples are provided of several technology areas in which UK contributions are planned, including: coated particle fuel characterisation, the behaviour of irradiated graphite, an examination of ceramic cladding materials, and the development of molten salt recycle technology.

  17. Studies of binary cerium(IV)-praseodymium(IV) and cerium(IV)-terbium(IV) oxides as pigments for ceramic applications

    International Nuclear Information System (INIS)

    It was investigated a series of pigments of general composition Ce1-x Prx O2, and Cex Tby O2, exhibiting radish and brown colors, respectively, and high temperature stability. The pigments were obtained by dissolving appropriate amounts of the pure lanthanide oxides in acids and precipitating the rare earths as mixed oxalates, which were isolated and calcined under air, at 10000 C. X-Ray powder diffractograms were consistent with a cubic structure for the pigments. Magnetic susceptibility measurements, using Gouy method, indicated the presence of Pr(IV) ions in the Ce1-x Prx O2 pigments and of Terbium predominantly as Tb(III) ions in the Ce-tb mixed oxides. A new method, based on suspension of solid samples in PVA-STB gels (STB = sodium tetradecaborate), was employed for the measurements of the electronic spectra of the pigments. The thermal behaviour the pigments was investigated by the calcination of the oxalates in the temperature range of 500 to 1200O C, from 10 to 60 minutes. (author)

  18. Materials for generation-IV nuclear reactors

    International Nuclear Information System (INIS)

    Materials science and materials development are key issues for the implementation of innovative reactor systems such as those defined in the framework of the Generation IV. Six systems have been selected for Generation IV consideration: gas-cooled fast reactor, lead-cooled fast reactor, molten salt-cooled reactor, sodium-cooled fast reactor, supercritical water-cooled reactor, and very high temperature reactor. The structural materials need to resist much higher temperatures, higher neutron doses and extremely corrosive environment, which are beyond the experience of the current nuclear power plants. For this reason, the first consideration in the development of Generation-IV concepts is selection and deployment of materials that operate successfully in the aggressive operating environments expected in the Gen-IV concepts. This paper summarizes the Gen-IV operating environments and describes the various candidate materials under consideration for use in different structural applications. (author)

    In this chapter, we illustrate benefits of thinking in terms of thread management techniques when using a centralized scheduler model along with interoperability of MPI and PThread. This is facilitated through an exploration of thread placement strategies for an algorithm modeling radiative heat transfer with special attention to the 61st core. This algorithm plays a key role within the Uintah Computational Framework (UCF) and current efforts taking place at the University of Utah to model next-generation, large-scale clean coal boilers. In such simulations, this algorithm models the dominant form of heat transfer and consumes a large portion of compute time. Exemplified by a real-world example, this chapter presents our early efforts in porting a key portion of a scalability-centric codebase to the Intel Xeon Phi coprocessor. Specifically, this chapter presents results from our experiments profiling the native execution of a reverse Monte-Carlo ray tracing-based radiation model on a single coprocessor. These results demonstrate that our fastest run configurations utilized the 61st core and that performance was not profoundly impacted when explicitly oversubscribing the coprocessor operating system thread. Additionally, this chapter presents a portion of radiation model source code, a MIC-centric UCF cross-compilation example, and less conventional thread management technique for developers utilizing the PThreads threading model.

    The complexation of Np(IV) with gluconic acid (GLU) under alkaline conditions was investigated in the absence of Ca by carrying out a series of sorption experiments. The decrease of Np(IV) sorption on the sorbing material at increasing concentrations of GLU was interpreted as the formation of Np(IV)-GLU aqueous complexes. The modelling of experimental data according to the Schubert method [1] confirmed the formation of a complex with a Np:GLU ratio 1: 1. The stoichiometry of the complex Np(OH){sub 4}GLU{sup -} was proposed based on the experimental observation that no proton exchange occurred during the course of the complexation reaction and that Np(OH){sub 4}(aq) was the predominant hydrolysis product in the absence of GLU. A log *{beta}{sup 0}{sub 1,4,1} = -2.92 {+-} 0.30 for the formation reaction Np{sup 4+} + 4H{sub 2}O + GLU{sup -} <=> Np(OH){sub 4}GLU{sup -} + 4H{sup +} was calculated based on the conditional stability constants determined from sorption experiments and using the Np(IV) thermodynamic data selected in the NEA reviews [2]. Linear free energy relationships (LFER) confirmed that the stoichiometry and stability of the Np(IV)-GLU complex characterized in this work are consistent with data available for Th(IV)-, U(IV)- and Pu(IV)-GLU complexes.

    As part of a study to characterize the detailed coordination behavior of Pu(IV), single crystal X-ray diffraction structures have been determined for Pu(IV) and Ce(IV) complexes with the naturally-occurring ligand maltol (3-hydroxy-2-methyl-pyran-4-one) and its derivative bromomaltol (5-bromo-3-hydroxy-2-methyl-pyran-4-one). Although Ce(IV) is generally accepted as a structural analog for Pu(IV), and the maltol complexes of these two metals are isostructural, the corresponding bromomaltol complexes are strikingly different with respect to ligand orientation about the metal ion: All complexes exhibit trigonal dodecahedral coordination geometry but the Ce(IV)-bromomaltol complex displays an uncommon ligand arrangement not mirrored in the Pu(IV) complex, although the two metal species are generally accepted to be structural analogs.

    2015-01-01

    In this paper, we studied the behavior of relativistic objects with anisotropic matter distribution considering Tolman IV form for the gravitational potential Z. The equation of state presents a quadratic relation between the energy density and the radial pressure. New exact solutions of the Einstein-Maxwell system are generated. A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. We show as the presence of an electrical field modifies the energy density, the radial pressure and the mass of the stellar object and generates a singular charge density.

    Cultured fibroblasts from mucolipidosis IV patients accumulated phospholipids when compared to normal controls or cells from other genotypes. The major stored compounds were identified as phosphatidylcholine, phosphatidylethanolamine and to a larger extent lysophosphatidylcholine and lysobisphosphatidic acid. Pulse chase experiments of 32P-labelled phospholipids showed increased retention of these compounds in the mucolipidosis IV lines throughout the pulse and chase periods. Phospholipase A1, A2, C, D and lysophospholipase showed normal activity in the mucolipidosis IV lines and thus the metabolic cause for this storage remains to be identified. PMID:3139925

    the First Half of 21st Century' approved by the Russian Federation Government (fast reactors, closed fuel cycle and advanced reprocessing technologies, high temperature gas cooled reactors, etc.); second, Russian nuclear enterprises may get orders for works on many other trends. With its tremendous background and high potential for the experimental verification of nearly all trends selected within the Generation-IV, Russia is still a preferable partner for many Western entities. Namely this lies behind the Resolution of Generation-IV International Forum welcoming Russian participation at as early as possible stage. At the same time, Russia joining the Generation-IV would not make a whole deal. The reason is that Generation-IV international program was initiated by the U.S.A. and pursues mostly the U.S. interests. Its scope matches the demands of only a few leading countries, the issues of sustainable global development and energy demands of the developing countries are left out. In this context, Russia shall unconditionally go on with the advancement and promotion of the INPRO. Different from Generation-IV, the initiated by Russia INPRO international project was initially targeted at the interests of global community. Hence, the provided more profound level of consideration for global and regional aspects of nuclear power, including the spectrum of possible solutions such as fuel and NPP leasing, multi-national ownership of nuclear fuel cycle centers, etc. It is anticipated that INPRO would involve a more broad spectrum of the technology proposals for innovative reactors and nuclear fuel cycles, the spectrum that would meet the demands of nearly all countries in the world, including not only those that are nuclear stakeholders, but also those that intend only to be users. Proposals for INPRO may include different options for the advanced light water reactors, a variety of nuclear batteries for autonomous energy supply, the ones to be leased included, reactors for heat

  2. Planning and setting objectives in field studies: Chapter 2

    Science.gov (United States)

    Fisher, Robert N.

    2016-01-01

    This chapter enumerates the steps required in designing and planning field studies on the ecology and conservation of reptiles, as these involve a high level of uncertainty and risk. To this end, the chapter differentiates between goals (descriptions of what one intends to accomplish) and objectives (the measurable steps required to achieve the established goals). Thus, meeting a specific goal may require many objectives. It may not be possible to define some of them until certain experiments have been conducted; often evaluations of sampling protocols are needed to increase certainty in the biological results. And if sampling locations are fixed and sampling events are repeated over time, then both study-specific covariates and sampling-specific covariates should exist. Additionally, other critical design considerations for field study include obtaining permits, as well as researching ethics and biosecurity issues.

  3. Non-Imaging Detectors and Counters. Chapter 10

    International Nuclear Information System (INIS)

    Historically, nuclear medicine has been largely an imaging based specialty, employing such diverse and increasingly sophisticated modalities as rectilinear scanning, (planar) gamma camera imaging, single photon emission computed tomography (SPECT) and positron emission tomography (PET). Non-imaging radiation detection, however, remains an essential component of nuclear medicine. This chapter reviews the operating principles, performance, applications and quality control (QC) of the various non-imaging radiation detection and measurement devices used in nuclear medicine, including survey meters, dose calibrators, well counters, intra-operative probes and organ uptake probes. Related topics, including the basics of radiation detection, statistics of nuclear counting, electronics, generic instrumentation performance parameters and nuclear medicine imaging devices, are reviewed in depth in other chapters of this book

    Full Text Available Diabetes mellitus-2 [NIDDM/T2D] is a metabolic disorder that is characterized by Insulin resistance and hyperglycemia. DPP IV inhibitors have been investigated as new target for T2D treatment. DPP IV inhibition improves the impaired insulin secretion and decrease postprandial concentrations of glucagon by enhancing the incretin hormone levels of Glucagon like peptide-1(GLP-1 and Glucose dependent insulinotropic polypeptide (GIP. Many research activities in this area resulted in the introduction of Sitagliptin and Vildagliptin (Only in Europe and few active molecules entered into clinical trials, for example Alogliptin. Treatment of this metabolic disorder especially in the early stages of the disease by DPP IV inhibition has been recognized as a validated and large numbers of inhibitors are currently in various stages of preclinical or clinical development. This review summarizes the development of DPP IV inhibitors, molecular mechanism, and etc.

    Tri-n-butyl phosphate (TBP), used as the extractant in nuclear fuel reprocessing, shows superior extraction abilities for Pu(IV) over a large number of fission products including Zr(IV). We have applied density functional theory (DFT) calculations to explain this selectivity by investigating differences in electronic structures of Pu(NO3)4·2TBP and Zr(NO3)4·2TBP complexes. On the basis of our quantum chemical calculations, we have established the lowest energy electronic states for both complexes; the quintet is the ground state for the former, whereas the latter exists in the singlet spin state. The calculated structural parameters for the optimized geometry of the plutonium complex are in agreement with the experimental results. Atoms in Molecules analysis revealed a considerable amount of ionic character to M-O{TBP} and M-O{NO3} bonds. Additionally, we have also investigated the extraction behavior of TBP for metal nitrates and have estimated the extraction energies to be -73.1 and -57.6 kcal/mol for Pu(IV) and Zr(IV), respectively. The large extraction energy of Pu(IV) system is in agreement with the observed selectivity in the extraction of Pu. PMID:27248966

  19. IUPAC critical evaluation of the rotational–vibrational spectra of water vapor. Part IV. Energy levels and transition wavenumbers for D216O, D217O, and D218O

    International Nuclear Information System (INIS)

    This paper is the fourth of a series of papers reporting critically evaluated rotational–vibrational line positions, transition intensities, pressure dependences, and energy levels, with associated critically reviewed assignments and uncertainties, for all the main isotopologues of water. This paper presents energy level and transition data for the following doubly and triply substituted isotopologues of water: D216O, D217O, and D218O. The MARVEL (Measured Active Rotational–Vibrational Energy Levels) procedure is used to determine the levels, the lines, and their self-consistent uncertainties for the spectral regions 0–14 016, 0–7969, and 0–9108 cm−1 for D216O, D217O, and D218O, respectively. For D216O, D217O, and D218O, 53 534, 600, and 12 167 lines are considered, respectively, from spectra recorded in absorption at room temperature and in emission at elevated temperatures. The number of validated energy levels is 12 269, 338, and 3351 for D216O, D217O, and D218O, respectively. The energy levels have been checked against the ones determined, with an average accuracy of about 0.03 cm−1, from variational rovibrational computations employing exact kinetic energy operators and an accurate potential energy surface. Furthermore, the rovibrational labels of the energy levels have been validated by an analysis of the computed wavefunctions using the rigid-rotor decomposition (RRD) scheme. The extensive list of MARVEL lines and levels obtained is deposited in the Supplementary Material of this paper, in a distributed information system applied to water, W@DIS, and on the official MARVEL website, where they can easily be retrieved. - Highlights: • All published transitions are collected and analyzed. • A set of validated rovibrational transitions are presented. • Experimental energy levels for all three D2O isotopologues are determined. • Synthetic spectra are presented using these validated energy levels

  20. Synthesis, characterization and thermal behaviour of cadmium (II) complexes of photosubstituted octacyano-molybdate(IV) and -tungstate(IV) with ethylenediamine

    International Nuclear Information System (INIS)

    Photosubstituted ethylenediamine complexes of M(CN)84- [where M =Mo(IV) or W(IV)] with cadmium (II) chloride have been synthesized and characterized by infrared (IR), thermogravimetric (TG) and differential scanning calorimetry (DSC). Both Mo(IV) and W(IV) show similar stoichiometric as well as thermal decomposition behaviour. The assigned general formula is Cd[M(CN)3(OH)(C2H8N2)2](C2H8N2) Cl2XH2O [where M = Mo(IV) for which X = 1(I) and M = W(IV) for which X = 2 (II)]. The presence of CN-, OH- and C2H8N2 has been shown by observed characteristic IR peaks. The extra absorption bands appearing in complex (II) are due to librational modes of water which show the formation of hydrogen bonding, which is also supported by TG analysis. The loss of these absorption bands rules out this type of bonding in (I). Both the complexes decompose in three steps up to 650 degC after which there is no change. DSC of the complexes also shows three transitions, two exothermic and one endothermic. On the basis of TG and DSC thermograms, mechanism for the decomposition of each step has been shown. Kinetic parameters like activation energy (Ea), frequency factor (A) and entropy of activation (ΔS) have been calculated using different integral methods. (author)

  4. Group IV direct band gap photonics: Methods, Challenges and Opportunities

    Directory of Open Access Journals (Sweden)

    Richard eGeiger

    2015-07-01

    Full Text Available The concept of direct band gap group IV materials offers a paradigm change for Si-photonics concerning the monolithic implementation of light emitters: The idea is to integrate fully compatible group IV materials with equally favorable optical properties as the chemically incompatible group III-V-based systems. The concept involves either mechanically applied strain on Ge or alloying of Ge with Sn and permits to drastically improve the insufficient radiative efficiency of Ge. The favorable optical properties result from a modified band structure transformed from an indirect to a direct one. The first demonstration of such a direct band gap laser, accomplished in GeSn, exemplifies the capability of this new concept. These systems may permit a qualitative as well as a quantitative expansion of Si-photonics into traditional but also new areas of applications, provided they can be operated energy efficiently, under ambient conditions and integrated with current Si technologies. This review aims to discuss the challenges along this path in terms of fabrication, characterization and fundamental understanding, and will elaborate on evoking opportunities of this new class of group IV-based laser materials.

    de Andrés-García, I.; Alonso-Medina, A.; Colón, C.

    2016-01-01

    In this paper, we present theoretical Stark widths and shifts calculated corresponding to 66 spectral lines of Sn IV. We use the Griem semi-empirical approach and the COWAN computer code. For the intermediate coupling calculations, the standard method of least-squares fitting from experimental energy levels was used. Data are presented for an electron density of 1017 cm-3 and temperatures T = 1.1-5.0 (104 K). The matrix elements used in these calculations have been determined from 34 configurations of Sn IV: 4d10ns(n = 5-10), 4d10nd(n = 5-8), 4d95s2, 4d95p2, 4d95s5d, 4d85s5p2 and 4d105g for even parity and 4d10np(n = 5-8), 4d10nf (n = 4-6), 4d95snp(n = 5-8), 4d85s25p and 4d95snf (n = 4-10) for odd parity. Also, in order to test the matrix elements used in our calculations, we present calculated values of radiative lifetimes of 14 levels of Sn IV. There is good agreement between our calculations and the experimental radiative lifetimes obtained from the bibliography. The spectral lines of Sn IV are observed in UV spectra of HD 149499 B obtained with the Far Ultraviolet Spectroscopic Explorer, the Goddard High Resolution Spectrograph and the International Ultraviolet Explorer. Theoretical trends of the Stark broadening parameter versus the temperature for relevant lines are presented. Also our values of Stark broadening parameters have been compared with the data available in the bibliography.

    2016-02-01

    The spectral-luminescent and thermochromic properties of complex compounds of the composition Cs2TeHal6 (Hal = Cl, Br, I) are studied. The interrelation between the geometric structure and spectral-luminescent properties is studied using the example on complex compounds of tellurium(IV) halides with cesium. The Stokes shift and the luminescence intensity of Te(IV) ions with island octahedral coordination are found to depend on the position of the A band in the luminescence excitation spectra, the diffuse reflection, and the energy of the luminescent 3 P 1 → 1 S 0 transition of the tellurium(IV) ion. The maximum luminescence intensity and the minimum Stokes shift at 77 and 300 K are observed for Cs2TeCl6. The geometrical and electronic factors responsible for luminescence intensification in Te(IV) complexes under study are analyzed.

    Full Text Available In the present study, a theoretical study of 1,1-diaminohexaazidocyclo-tetraphophazene (DAHA and its isomers has been performed, using quantum computational density functional theory (B3LYP and B3PW91 methods with 6-31G* and 6-31G** basis sets implemented in Gaussian 03 program suite. Molecular structure and bonding, vibrational frequencies, Milliken population analysis, and natural bond orbit (NBO have been studied. The heats of formation from atomization energies have also been calculated based on the optimized geometry. The obtained heats of formation data are compared with their homologous cyclophosphazene in order to demonstrate the accuracy of the methods, which indicate that the studied compounds might be potentially used as high energetic materials. In addition, the relative stability of five isomers have been deduced based on the total energy and the gap of frontier orbital energies.

We introduce a plasmonic platform based on epitaxial n-type Ge grown on standard Si wafers by means of low-energy plasma-enhanced chemical vapor deposition. Due to the large carrier concentration achieved with P dopants and to the compatibility with the existing CMOS technology, SiGe plasmonics hold promises for mid-IR applications in optoelectronics, IR detection, sensing, and light harvesting. As a representative example, we show simulations of mid-IR plasmonic waveguides based on the experimentally retrieved dielectric constants of the grown materials.

  16. Chapter 6. Models of groundwater ages and residence times

    International Nuclear Information System (INIS)

    CFC ages are generally based on absolute concentrations. As a result, when waters of different ages mix, the CFC concentration changes and so does the apparent age. Because CFC concentrations in the atmosphere are not a linear function of time, the apparent age is not necessarily proportional to the fraction of each component of water in the mixture. In this chapter, more general models of groundwater age distributions in simple aquifer types are reviewed, as well as how the age distribution relates to aquifer properties

  17. Chapter 2. Use of tracer technology in mineral fertilizer management

    International Nuclear Information System (INIS)

    This chapter provides background information on fertilizer nitrogen (N) consumption and production (2.1) and estimates of future requirements, followed by methods for the measurement of fertilizer N use efficiency (2.2). Aspects relevant to the use of fertilizer N in agricultural production systems, such as factors affecting its efficiency and loss (2.3), and interactions with other N sources and soil testing for providing fertilizer recommendations, are discussed, as are approaches/strategies to improve fertilizer N efficiency (2.4), with particular emphasis on the use of isotopic tracers.

    All four cases examined in detail thus far in the two previous chapters (three related to the Shihābs, in addition to a regular Beirut case similar in its structure to that of Bashīr III) reveal an eagerness to go beyond the limitations imposed by both Maronite canon law and Ḥanafī practice. But a great deal of conservatism also reveals itself in that the court procedures, which by and large consisted of legal subterfuges, did not touch upon the substance of the law. However, even with the ex...

    Zirconium (IV) soaps of butyric, valeric and stearic acid were prepared and characterised by infrared spectroscopy. Thermal decomposition was studied by dynamic thermogravimetry and differential thermometry in the temperature range of 200-800 C. The order of decomposition was found to be zero for all soaps. The activation energies {Delta}E were found to be: 8.233, 8.620 and 7.181 kJ mol{sup -1} for butyrate, valerate and stearate respectively. The frequency factor, Z, entropy change {Delta}S and free energy change {Delta}G were calculated and a probable decomposition mechanism proposed. (orig.) [Deutsch] Aus Butter-, Valerian- und Stearinsaeure wurden die entsprechenden Zirconium(IV)seifen hergestellt und durch ihre Infrarotspektren charakterisiert. Ihre thermische Zersetzung wurde mittels dynamischer Thermogravimetrie und Differentialthermometrie im Bereich von 200-800 C untersucht. Die Zersetzungsreaktion war fuer alle untersuchten Seifen von nullter Ordnung. Fuer die Aktivierungsenergien, {Delta}E, wurden Werte von 8,233, 8,620 und 7,181 kJ mol{sup -1} fuer Butyrat, Valerat bzw. Stearat gefunden. Der Frequenzfaktor Z, die Entropieaenderung {Delta}S und die Aenderung der freien Energie {Delta}G werden berechnet, und es wird ein moeglicher Mechanismus fuer die Zersetzung angegeben. (orig.)
