  1. Oxide fuel fabrication technology development of the FaCT project (1). Overall review of fuel technology development of the FaCT project

    International Nuclear Information System (INIS)

    The FaCT project is in progress in Japan for the commercialization of fast reactor cycle system. The development goal of the fuel in the FaCT project is a low-decontaminated TRU homo-recycling in a closed cycle and extension in average discharge burn-up to 150 GWd/t. Research and development on innovative technologies concerning the short process, remote maintenance and cooling system of automatic fuel production equipments, long life cladding material and control of oxygen potential have been conducted in phase I of the FaCT project. As the result of various test including 600 g batch MOX tests, it is concluded that the short process is available to fuel pellet fabrication of the FaCT project. Although cold mock-up tests on test model of some typical process equipments suggest possibilities of remote maintenance of automatic fuel fabrication equipment, it is concluded that it still needs further efforts to judge the operability of the completely remote fabrication for low-decontaminated TRU fuel. A cold mock-up test on fuel pin assembling equipment show that influence of decay heat of MA can be managed by cooling system. Irradiation tests in BOR-60 indicate that 9Cr-ODS possess the satisfactory in-reactor performance as the long life cladding material if homogeneity of alloy element is adequately controlled. Modification of cladding tube fabrication process to ensure homogeneity and further development of measures to control oxygen potential inside the fuel pin are noxygen potential inside the fuel pin are necessary to reach the burn-up target of the FaCT project.

  3. Fast reactor cycle technology development project (FaCT project). Phase I report

    International Nuclear Information System (INIS)

    JAEA and JAPC launched Fast Reactor Cycle Technology Development Project (FaCT) in 2006. 'The Japan sodium-cooled fast reactor (JSFR) with MOX fuel, the advanced aqueous reprocessing, and the simplified pelletizing fuel fabrication systems' have been studied as a main concept in the FaCT project. In 2010, a judgment on whether the innovative technologies should be adopted was made. In 2015, the design concept of the demonstration and commercial facilities for fast breeder reactor cycles that may fulfill the development targets as well as the R and D programs aimed at their commercialization are to be proposed. The adoption judgment of the innovative technologies was conducted focusing on the abovementioned main concept. To evaluate the sodium-cooled fast reactor (with MOX fuel) in terms of its design adequacy as a reactor system, 13 tasks of the innovative technologies were reduced to 10 tasks to fit more precisely with the targeting evaluation technology. As the result, 8 tasks were rated as adoptable. However, for a steam generator with double-walled straight tube, it was judged that heat exchanger tube with a protective tube should be selected as an alternative technology. Further, the assessments for the high-burnup reactor core and fuels are to be conducted in the two stages. Then finally cladding tubes materials will be selected on top of the judgment of necessity for alternative materials. For advanced aqueous reprocessing, 3 tasks of the innovative technologies were rated as adoptable. And, it was judged that the evaluation of other 3 tasks (i.e., effective uranium recovery system by crystallization technology, MA recovery technology by extraction chromatography method, waste reduction technology or waste polarizing technology) should be continued. For simplified pelletizing fuel fabrication, 3 tasks of the innovative technologies were rated as adoptable. And, it was judged that the evaluation of other 2 tasks (i.e., sintering and O/M ratio adjustment technique, in-cell remote handling technology) should be continued. The achievement of the performance targets presented by Japan Atomic Energy Commission was evaluated for the concept of the commercial facilities for FBR cycles, established based on the result of the adoption judgment for the innovative technologies. The purpose of this evaluation is to evaluate the degree of achievement at this time in the midterm stage till 2015, to affirm the validity of the direction of R and Ds and to draw out challenges toward future R and Ds. As a result of the evaluation, it has been revealed that the performance goals have been almost achieved, and some challenges which may indicate the direction of future R and Ds have been drawn out.

  4. Overview of fast reactor cycle system technology development project (FaCT) phase 1 and future direction

    International Nuclear Information System (INIS)

    The fast reactor (FR) and its related fuel cycle are being developed in order to mainly achieve sustainable energy supply system and reduce environment burden in Japan. Japan Atomic Energy Agency (JAEA) and electric utilities initiated the Fast Reactor Cycle System Technology Development Project (FaCT), which is commonly known as 'FaCT project', in cooperation with manufacturer, universities and research institutes in JFY2006. In the FaCT project, design studies on a main FR cycle concept, i.e. 'Sodium-cooled FR with MOX fuel, advanced aqueous reprocessing process, and simplified MOX pellet fabrication process' selected in the feasibility study in which various FR cycle candidate concepts were researched widely before JFY2005, are being performed. Further, innovative key technologies adopted in our FR cycle concept, ten technologies for reactor, six for reprocessing plant, five for fuel fabrication plant, are being developed experimentally and analytically. In JFY2010, the results of R and D and several project decisions in the first 5-years of the FaCT project, namely the FaCT phase 1 (JFY2006-2010), were summarized. We will mainly introduce the concrete results of the FaCT phase 1 and future direction in our full paper. It was preliminary decided whether each innovative key technology can be actually adopted in the commercial FR cycle plants on the basis of the R and D results by JAEA, manufactures and utilities. Eight of ten technologies for reactor were adopted. On technologies for reactor were adopted. One of the others, 'Double walled straight tube steam generator' has been determined to be replaced alternative option 'Protective walled straight tube steam generator'. As for the last one, high burn-up fuel technology, research for selection of cladding tube material will be continued. Three of six technologies for reprocessing plant were adopted. As for the others, 'Uranium crystallization process', 'MA recovery by extraction chromatography process', and 'Waste reduction', research for decision will be continued. Regarding fabrication plant, three of five technologies were adopted. Research for decision will be continued for two other technologies, 'In-cell remote facility' and 'Sintering and O/M adjusting technology'. After the decision about the adoption of the key technologies, JAEA estimated the achievement of the performance of the commercial plant concepts in this stage compared with the targets set by Atomic Energy Commission of Japan. As a result, accomplishment for the targets was basically confirmed and the issues were clarified toward next R and D activities. Though the development plan of the FR and its fuel cycle will be reconsidered in Japan due to the accident of Fukushima Dai-ichi nuclear power station by the massive earthquake occurred in March 11, 2011, we will progress steadily to realize the commercialization of FR and its fuel cycle in around 2050 while enhancing the safety and reliability of the FR cycle concept.

  5. Development of FR construction cost estimation method in FaCT (Fast reactor Cycle Technology development) project

    International Nuclear Information System (INIS)

    Full text: The economic competitiveness is the crucial issue for FR plant. Within the flow of FaCT, the commodity shall be reduced by introducing a compact design with the innovative technologies, although the ISI capability shall be required to ensure the plant reliability as the commercial reactor. In order to evaluate the economy for the Japan Sodium-cooled Fast Reactor (JSFR), the account code named SCALLE (Sum of Cost Account Leading to future Logistics Economy) has been developed, in which the basic methodology is bottom up of component costs based on the amount of material data and the corresponding unit cost. The amount of material is evaluated based on the JSFR conceptual design study. The unit costs for materials and structures are derived from the value of public documents about FR and LWR design etc. mainly on the EEDB (Energy Economic Data Base) of U.S. DOE. Cost evaluation accounts are classified considering JSFR system configuration. The code enables to take into account economical effect of learning and common use of balance of plant to evaluate a JSFR twin plant concept and NOAK (Nth of a Kind) as well as FOAK (First of a Kind). FOAK cost is assumed 30% of the overnight cost based on the document published the Chicago Univ. The learning effect factor defined as 'ratio of cost reduction when the quantity of production double', and set 6% as equipment cost, 10% as site labor cost and 3% as indirect cost based on the document related to the Generation IV the document related to the Generation IV deliberation. The difference between domestic and foreign prices and the price fluctuation are taken into account using economic indexes, for example, 'Producer Price Index' published by US Bureau of Labor Statics when we convert the value of equipment cost and material cost in US from document published year to wanted estimation year, and so on. The validation and verification of SCALLE code is carried out by evaluating the construction cost of past demonstration FR plant designed in Japan, and comparing evaluated value by SCALLE code with the evaluated value at the time. As a example of the JSFR construction cost estimation, the ratio of NOAK cost is 74% of FOAK cost.This code is used as basic information to evaluate cost of power generation in FaCT economics evaluation.

    McNeil, Ronald D.

    2001-10-01

    Information technology advances are spawning visions of radically altered modus operandi for commerce, education, business, information storage and receival. Proponents of virtual technology domination offer a world of instant communications, information sharing, and binary commerce. Some express alarm to the electronic visionaries and see an expected world vacated of human interactions, which is populated by e-hermits. The reality is that access to the Internet is becoming pervasive worldwide and affords a virtual community and markets. Governments, education, markets, businesses and consumers are rushing to exploit and adjust to an electronic, virtual world. The exploitation and adjustment to this an 'ether-world' transcends boundaries is a challenge to stakeholders. Public policy, international agreements, education, businesses and consumers face monumental change in the way they live and conduct their lives. As with most paradigms shifts, pioneers rush forward and launch a myriad of new startups with many failing and some standing the test of time and utility. An example is the early pioneers in North America who headed westward to in search of a new vision of riches. They established towns, developed farms, dug mines and began new businesses. However, many of the pioneers moved from one venture to another. Some of their endeavors ended with ghost towns, abandoned farms and mines, and bankrupt businesses. In the end, however, a great nation was born. This author expects the ether-world to go through similar starts, fits, and adjustments before it emerges as a more stable part of the fabric of society.

  16. Oxide fuel fabrication technology development of the fact project. (2) Small-scale hot tests on agitating granulation method using water for MOX pellet production

    International Nuclear Information System (INIS)

    In the fabrication process of oxide fuels for light water reactors (LWRs) and for fast breeder reactors (FBRs), uranium-plutonium mixed oxide (MOX) raw powder is granulated in prior to pellet pressing. Organic powder such as zinc stearate is usually mixed as a binder for granulation. This organic powder is removed during preliminary heating at around 800degC before sintering, however the residue and its decomposed material tend to contaminate inside the sintering furnace, which might drop the heat transfer performance or cause a blockage inside the exhaust ventilation. Therefore, it is necessary to perform frequent cleanup which results in higher operational cost. If water is used instead of the organic powder, most of water in the powder can be removed by drying before pressing, thus the process for preliminary heating can be skipped and the new process can also be free from the residue. This is one of the key benefits of the 'simplified pelletizing method' we are advancing. The test was performed in a small-scale hot apparatus as a part of the study on simplified pelletizing fuel fabrication system adopted by the 'FaCT' project. Purpose of the experiments we have done was to establish the conditions of agitating-granulation method and the apparatus to add uniformly the adequate amount of water as a binder to obtain sufficient flow-ability of the granules. In this study, MOX raw powder was prepared by the microwave heating (MH) method in which 20% Pu - 80% U mixed niH) method in which 20% Pu - 80% U mixed nitrate solution were de-nitrated. Then, the product was calcined at 750degC in the air and subsequently reduced at the same temperature under 5% H2 - 95% N2 gas. The granulation tests were carried out using a stirring blade which compresses moderately the powder and mixes the powder and water uniformly. The capacity of the vessel of the apparatus was 5 L. The sample weight was 600 g for a batch. The proportion of water to powder was changed from 13 to 17 weight%. Before granulation, the distribution of particle sizes of raw powder was measured by a Laser type analyzer. After granulation, the distribution was measured by sieving the granules through 9 meshes of successive sizes from 45 to 1,000 ?m. The flow-ability of the granules was measured by a powder tester based on ASTM. From these results, the performances and the best apparatus operating conditions of granulating the MOX raw powder were evaluated. In conclusion, the granules of 120-140 ?m in major diameter and 75-77 in flow-ability were obtained with water addition ratio of 113 wt.%, despite the narrow range of operating conditions. (author)

  17. String Theory: Basic Facts and Recent Developments

    International Nuclear Information System (INIS)

    String theory is formulated consistent with the principles of Quantum mechanics and a Special theory of relativity. This puts strong constraints on the theory: a Dimension of space = 9, time=1 (instead of 3+1), and in (9+1) dimensions there are only five fully consistent string theories. The problem of having six extra dimensions can be resolved using the idea of Compactification: Taking 6 of the 9 dimensions to describe a small compact space instead of infinite flat space. When the size of the compact space is smaller that the resolution of the most powerful microscope, the space will appear to be 3 dimensional. There are many possible ways to compact string theory. These different compactifications correspond to different phases/vacua of string theory. The apparent laws of nature e.g. spectrum and interactions of the elementary 'particles' depends on which phase of string theory we are in. String theory is like a big room with five windows, with different objects in the room representing different phases and the five windows representing the five string theories. Some phases of string theory look very similar to the theory that describes our world. The main obstacle to connecting string theory to experiment is the existence of huge number of phases of string theory. It is even conceivable that different parts of the universe are in different phases of string theory, and we happen to see one particular phase because we live in some particular region of the universe. n some particular region of the universe. Unless we can identify precisely which phase describes the environment in which we live, we cannot make precise predictions which can be tested in experiment. Given this situation it would seem that until we can find the right phase of string theory which describes our world, there cannot be any further progress. Despite this there has been significant progress in various directions, often by cleverly turning the landscape to our advantage. The recent Developments concern: the Conceptual issues, the Developments within string theory, the Exploration of the landscape, the Applied string theory, and the String motivated/induced developments in quantum field theory. This presentation shows few examples of each type

    The first Danish commercial wind turbines were installed in the late 1970s. Over the last 20 years the Danish wind turbine market has been relatively stable concerning annual installations, and the wind turbine technology has been able to develop continuously. This gives a unique time track for technology analysts. The aim of this paper is to extract reliable information on this time track from existing archives and statistics. Seven generations of wind turbine technology have been identified mainly based on `characteristic` rotor diameters. The technological development of each generation is described using indicators such as: market share in Denmark, generator size, rotor diameter, hub height, electricity production and productivity. Economical indicators comprise: costs of turbine and standard foundation. (au)

    The increasing penetration of wind power in electrical networks requires solutions for more sophisticated electrical performance of wind parks. Therefore ENERCON has developed a number of technical solutions to cover these advanced grid requirements: ENERCON's turbines of the latest generation are equipped with FACTS (Flexible AC Transmission System) capabilities. These enhanced power electronic devices are the basis to operate the wind turbines e.g. as a STATCOM (static compensator) to deliver reactive power independently from wind speed. This new performance gives excellent possibilities for operating a wind park with a voltage control system (VCS) and supporting power system stability even during severe faults. The wind farm can deliver ancillary services like reactive power supply and contribute significantly to an improved power system stability. (au)

    This chapter describes the present mainstream development of the wind turbine technology at present. The turbine technology development trend is characterized by up-scaling to turbines with larger capacity for both onshore and offshore applications, larger rotors and new drivetrain solution, including the direct-drive solution without gearbox. The technology solutions are strongly influenced by the development of the international industry with a global market for components and a trend towards a “shared” development effort in collaboration between the OEM’s and component sub-suppliers. Wind turbine blades and towers are very large series-produced components, which costs and quality are strongly dependent on the manufacturing methods. The industrial wind energy sector is well developed in Denmark, and the competitive advantage of the Danish sector and the potential for job creation will be discussed. Finally, the ongoing development of standards and certification of technology and wind turbine plants will be described.

Routines emerge, develop and change in close relation with different kinds of everyday technologies and in this article these processes will be investigated from three different perspectives: an historical perspective of how new technologies have entered homes, a consumer perspective of how both houses and new technologies are purchased and finally, as the primary part of the article, a user perspective of how routines develop while these technologies are being used. In the conclusion these insights are discussed in relation to possible ways of influencing routines.

    Bringing modern energy to the world's poor is an urgent necessity. Although steady progress is made in expanding the use of modern household energy services in developing countries, in both scenarios many people still depend on traditional biomass in 2030. Action to encourage more efficient and sustainable use of traditional biomass and help people switch to modern cooking fuels and technologies is therefore urgent.

    Free-piston Stirling power converters have the potential to meet the many future space power requirements for a wide variety of applications with less mass, better efficiency, and less total area (collector and radiator) than other power converter options. These benefits result in significant dollar savings over the projected mission lifetime. The National Aeronautics and Space Administration (NASA)—Lewis Research Center (LeRC), which has the responsibility to evaluate and develop power technologies that can satisfy anticipated future space mission power requirements, has been developing free-piston Stirling power converters and is bringing the Stirling technology to readiness. As the principal contractor to NASA-LeRC, Mechanical Technology Incorporated (MTI) is under contract to develop the necessary space Stirling technology but also demonstrate the readiness of the technology in two generations of full-scale power converters. The first generation Stirling power converter, the component test power converter (CTPC), initiated cold end testing at the end of 1991, with hot testing scheduled during 1992. This paper reviews test progress of the CTPC including the initial hot engine test results. Modifications incorporated into the CTPC from the earlier space power demonstrator engine are reviewed as well.

    The Wind and Water Power Program supports the development of marine and hydrokinetic devices, which capture energy from waves, tides, ocean currents, the natural flow of water in rivers, and marine thermal gradients, without building new dams or diversions. The program works closely with industry and the Department of Energy's national laboratories to advance the development and testing of marine and hydrokinetic devices. In 2008, the program funded projects to develop and test point absorber, oscillating wave column, and tidal turbine technologies. The program also funds component design, such as techniques for manufacturing and installing coldwater pipes critical for ocean thermal energy conversion (OTEC) systems. Rigorous device testing is necessary to validate and optimize prototypes before beginning full-scale demonstration and deployment. The program supports device testing by providing technology developers with information on testing facilities. Technology developers require access to facilities capable of simulating open-water conditions in order to refine and validate device operability. The program has identified more than 20 tank testing operators in the United States with capabilities suited to the marine and hydrokinetic technology industry. This information is available to the public in the program's Hydrodynamic Testing Facilities Database. The program also supports the development of open-water, grid-connected testing facilities, as well as resource assessments that will improve simulations done in dry-dock and closed-water testing facilities. The program has established two university-led National Marine Renewable Energy Centers to be used for device testing. These centers are located on coasts and will have open-water testing berths, allowing researchers to investigate marine and estuary conditions. Optimal array design, development, modeling and testing are needed to maximize efficiency and electricity generation at marine and hydrokinetic power plants while mitigating nearby and distant impacts. Activities may include laboratory and computational modeling of mooring design or research on device spacing. The geographies, resources, technologies, and even nomenclature of the U.S. marine and hydrokinetic technology industry have yet to be fully understood or defined. The program characterizes and assesses marine and hydrokinetic devices, and then organizes the collected information into a comprehensive and searchable Web-based database, the Marine and Hydrokinetic Technology Database. The database, which reflects intergovernmental and international collaboration, provides industry with one of the most comprehensive and up-to-date public resources on marine and hydrokinetic devices.

  20. Robotics Technology Development Program

    International Nuclear Information System (INIS)

    The Robotics Technology Development Program (RTDP) is a ''needs-driven'' effort. A lengthy series of presentations and discussions at DOE sites considered critical to DOE's Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination ampersand Dismantlement (D ampersand D). The RTDP Group realized that much of the technology development was common (Cross Cutting-CC) to each of these robotics application areas, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT ampersand E) process urged an additional organizational break-out between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). The RDTP is thus organized around these application areas -- TWR, CAA, MWO, D ampersand D and CC ampersand AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas

    This technology development plan is designed to provide a clear understanding of the research and development direction necessary for the qualification of nuclear grade graphite for use within the Next Generation Nuclear Plant (NGNP) reactor. The NGNP will be a helium gas cooled Very High Temperature Reactor (VHTR) with a large graphite core. Graphite physically contains the fuel and comprises the majority of the core volume. Considerable effort will be required to ensure that the graphite performance is not compromised during operation. Based upon the perceived requirements the major data needs are outlined and justified from the perspective of reactor design, reatcor performance, or the reactor safety case. The path forward for technology development can then be easily determined for each data need. How the data will be obtained and the inter-relationships between the experimental and modeling activities will define the technology development for graphite R&D. Finally, the variables affecting this R&D program are discussed from a general perspective. Factors that can significantly affect the R&D program such as funding, schedules, available resources, multiple reactor designs, and graphite acquisition are analyzed.

    Electron Cyclotron Heating (ECH) is needed for plasma heating, current drive, plasma stability control, and other applications in fusion energy sciences research. The program of fusion energy sciences supported by U. S. DOE, Office of Science, Fusion Energy Sciences relies on the development of ECH technology to meet the needs of several plasma devices working at the frontier of fusion energy sciences research. The largest operating ECH system in the world is at DIII-D, consisting of six 1 MW, 110 GHz gyrotrons capable of ten second pulsed operation, plus two newer gyrotrons. The ECH Technology Development research program investigated the options for upgrading the DIII-D 110 GHz ECH system. Options included extending present-day 1 MW technology to 1.3 – 1.5 MW power levels or developing an entirely new approach to achieve up to 2 MW of power per gyrotron. The research consisted of theoretical research and designs conducted by Communication and Power Industries of Palo Alto, CA working with MIT. Results of the study would be validated in a later phase by research on short pulse length gyrotrons at MIT and long pulse / cw gyrotrons in industry. This research follows a highly successful program of development that has led to the highly reliable, six megawatt ECH system at the DIII-D tokamak. Eventually, gyrotrons at the 1.5 megawatt to multi-megawatt power level will be needed for heating and current drive in large scale plasmas including ITER and DEMO.

    The spent fuel coming from the PWR is one of the most difficult problems to be solved for the continuous use of nuclear power. It takes a few million years to be safe under the ground. Therefore, it is not easy to take care of the spent fuel for such a long time. Transmutation technology is the key technology which can solve the spent fuel problem basically. Transmutation is to transmute long-lived radioactive nuclides in the spent fuel into short-lived or stable nuclide through nuclear reactions. The long-lived radioactive nuclides can be TRU and fission products such as Tc-99 and I-129. Although the transmutation technology does not make the underground disposal totally unnecessary, the period to take care of the spent fuel can be reduced to the order of a few hundred years. In addition to the environmental benefit, transmutation can be considered to recycle the energy in the spent fuel since the transmutation is performed through nuclear fission reaction of the TRU in the spent fuel. Therefore, transmutation technology is worth being developed in economical aspect. The results of this work can be a basis for the next stage research. The objective of the third stage research was to complete the core conceptual design and verification of the key technologies. The final results will contribute to the establishment of Korean back end fuel cycle policy by providing technical guidelines.

  6. Patents and Downstream Innovation Suppresion - Facts or Fiction? : A Critique of the Use of Historical Sources Used in Support of the Thesis that Broad Patent Scope Enables the Suppresion or Hindrance of Downstream Useful Technology Development

    Merges and Nelson have proposed that pioneer patents of "broad" scope (where the claimed scope is typically broader than that strictly justified by the invention) enable their owners to "block" or "hold-up" downstream innovation. [1] They claim to have illustrated this thesis in such important cases of development as aircraft, the car, radio and electric lighting. Merges and Nelson quite logically use their work to question the value of Kitch's prospect theory of patents, [2] a theory that emphasises that the social value of patents is that they enable the coordination of technological development. This article re-examines Merges and Nelson's illustrative historical-empirical evidence and finds their thesis of downstream innovation suppression to be unwarranted by their empirical evidence. [3] Instead, Merges and Nelson have selected a number of important historical cases in which the administration of patents caused problems for the coordination of development. I argue that the pattern in the cases is that for idiosyncratic reasons the prospect function of patents has been "compromised" by the way the patents have been administered, variously by Congress, the Patent Office or the courts.

[2] Merges and Nelson, "On the Complex Economics of Patent Scope," 843. [3] Of more than 280 citations of this article listed in the ISI citation index, I can find none that critically-reanalyse the historical case evidence. I examined the titles of all of the 280-odd citing works and selected abstracts and papers, when the title or abstract seemed to suggest the possibility of critical revision.

    The beliefs people hold about the social and physical world are central to self-definition and social interaction. The current research analyzes reasoning about three kinds of beliefs: those that concern matters of fact (e.g., dinosaurs are extinct), preference (e.g., green is the prettiest color), and ideology (e.g., there is only one God). The domain of ideology is of unique interest because it is hypothesized to contain elements of both facts and preferences. If adults’ distinct reasonin...

The Research object: An alternative hybrid approach for synthesizing VSC-FACTS and -HVDC hybrid model is proposed. The results: the VSC- FACTS and -HVDC hybrid model is designed in accordance with the presented concepts of hybrid simulation. The developed model allows us to carry out adequate simulation in real time of all the processes in HVDC, FACTS devices and EPS as a whole without any decomposition and limitation on their duration, and also use the developed tool for effective solution of a design, operational and research tasks of EPS containing such devices.

In order to investigate the later phase of a SWR event, an experimental apparatus was designed and manufactured. The 620 data set have been obtained in the experiment of free surface fluctuation and an experimental correlation for the critical gas entertainment condition is additionally developed. For development of water into sodium leak detection technology, the properties from leak noises were extracted, and the tools for analyzing acoustic noises were constructed. The state-of-the-art on the flow and differential pressure measuring techniques in the piping system is investigated to develop new techniques which are applicable to high temperature sodium flow environment. The plan for the minimization of errors in temperature measurement was drawn up by analysing the error factors in temperature measurement.

    2010-10-01

    The Next Generation Nuclear Plant (NGNP) will be a helium-cooled High Temperature Gas Reactor (HTGR) with a large graphite core. Graphite physically contains the fuel and comprises the majority of the core volume. Graphite has been used effectively as a structural and moderator material in both research and commercial high-temperature gas-cooled reactors. This development has resulted in graphite being established as a viable structural material for HTGRs. While the general characteristics necessary for producing nuclear grade graphite are understood, historical “nuclear” grades no longer exist. New grades must be fabricated, characterized, and irradiated to demonstrate that current grades of graphite exhibit acceptable non-irradiated and irradiated properties upon which the thermomechanical design of the structural graphite in NGNP is based. This Technology Development Plan outlines the research and development (R&D) activities and associated rationale necessary to qualify nuclear grade graphite for use within the NGNP reactor.

    The objective of present study is to produce the experimental data for development and verification of computer codes for development of LMR and to develop the preliminary technologies for the future large scale verification experiments. A MHD experimental test loop has been constructed for the quantitative analysis of the effect of magnetic field on the sodium flow and experiments are carried out for three EM pumps. The previous pressure drop correlations are evaluated using the experimental data obtained from the pressure drop experiment in a 19-pin fuel assembly with wire spacer. An dimensionless variable is proposed to describe the amplitude and frequency of the fluctuation of free surface using the experimental data obtained from free surface experimental apparatus and an empirical correlation is developed using this dimensionless variable. An experimental test loop is constructed to measure the flow characteristics in IHX shell side and the local pressure drop in fuel assembly, and to test the vibration behaviour of fuel pins due to flow induced vibration. The sodium two-phase flow measuring technique using the electromagnetic flowmeter is developed and the sodium differential pressure drop measuring technique using the method of direct contact of sodium and oil is established. The work on the analysis of sodium fire characteristics and produce data for vlidation of computer code is performed. Perfect reopen time of self plugged leak path was observed to be about 130 minutes after water leak initiation. Reopen shape of a specimen appeared to be double layer of circular type, and reopen size of this specimen surface was about 2mm diameter on sodium side. In small water leakage experiments, the following correlation equation about the reopen time between sodium temperature and initial leak rate was obtained, {tau}{sub c} = {delta}{center_dot}g{sup -0.83}{center_dot}10{sup (3570/T{sub Na}-3.34)}, in 400-500 deg C of liquid sodium atmosphere. The characteristics of pressure propagation and gas flow, and pressure transient transferred to the IHX will be analyzed. The experimental data will be used for the primary verification of SPIKE code. The verified SPIKE code will be applied to the design of KALIMER secondary ststem an used to analyze the safety of equipment in sodium-water reaction. The hydrogen detector showed the characteristics of hydrogen leak detection delay. In the development of acoustic leak detection technology, considering the design conditions of the KALIMER steam generator, we predicted the limitation of water leak detection, the selection of acoustic sensor, and the construction of the DSP instrument. The experimental and simulated results on the frequencies of acoustic signal according to the leak level were compared.

    The first atmospheric event built only from infrasound arrivals was reported in the Reviewed Event Bulletin (REB) of the International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) in 2003. In the last decade, 48 infrasound stations from the International Monitoring System (IMS) have been installed and are transmitting data to the IDC. The infrasound component of the IMS daily registers infragenic signals originating from various sources such as volcanic eruptions, earthquakes, microbaroms, meteorites entering the atmosphere and accidental explosions. The IDC routinely and automatically processes infrasound data reviewed by interactive analysis; the detected and located events are then included in the IDC products. The IDC advances its methods and continuously improves its automatic system for the infrasound technology. The IDC focuses on enhancing the automatic system for the identification of valid signals and the optimization of the network detection threshold by identifying ways to refine signal characterization methodology and association criteria. An objective of this study is to reduce the number of associated infrasound arrivals that are rejected from the automatic bulletins when generating the reviewed event bulletins. A number of ongoing projects at the IDC will be presented, such as: - improving the detection accuracy at the station processing stage by enhancing the infrasound signal detector DFX-PMCC (Detection and Feature eXtraction - Progressive Multi-Channel Correlation) and by evaluating the performances of detection software. - separating infrasound data from other waveform technologies at the automatic network processing stage for technology development and for preparing the implementation of next generation of waveform association algorithm. Infrasound rules in Global Association (GA) are revisited to pursue a lower ratio of false alarms. - determining station noise for IMS infrasound, seismic and hydroacoustic stations sending data to the IDC. The data is used for assessing the network capability performances and for assisting station maintenance. It allows for the investigation of a method whereby an acoustic event source size could be indicated as a magnitude estimate.

    The objective of this project is to perform R and D on the essential technologies in nuclear material measurement and surveillance and verification system, and to improve the state of being transparent on the nuclear material management of DUPIC Fuel Development Facility (DFDF) through the evaluation of safeguard ability on non-proliferation fuel cycle and nuclear proliferation resistance. Nuclear material position scan system for the reduction of measurement error was developed for the spatial distribution search of spent fuel in DUPIC facility. Web-based realtime remote monitoring system was designed and constructed for satisfying the IAEA's performance criteria of continuous monitoring, and also developed a software for the function of remote control and message. And diversion paths in a proliferation resistant pyroprocess for SFR were analyzed and its protecting system against the diversion paths were suggested for enhancing proliferation resistance of advanced nuclear fuel cycle. These results could be used for planning the further R and D items in the area of safeguards. Those R and D results mentioned above would be helpful for increasing Korean nuclear transparency in the future.

  20. Patents and Downstream Innovation Suppresion - Facts or Fiction? : A Critique of the Use of Historical Sources Used in Support of the Thesis that Broad Patent Scope Enables the Suppresion or Hindrance of Downstream Useful Technology Development

    OpenAIRE

    Howells, John

    2009-01-01

    Merges and Nelson have proposed that pioneer patents of "broad" scope (where the claimed scope is typically broader than that strictly justified by the invention) enable their owners to "block" or "hold-up" downstream innovation. [1] They claim to have illustrated this thesis in such important cases of development as aircraft, the car, radio and electric lighting. Merges and Nelson quite logically use their work to question the value of Kitch's prospect theory of patents, [2] a theory that ...

  5. Asian and African Development Trajectories Revisiting Facts and Figures

    Directory of Open Access Journals (Sweden)

    Gilles Carbonnier

    2013-05-01

    Full Text Available In today’s dominant discourse, the development trajectory of many East Asian countries is pictured as a success, whereas that of many sub-Saharan African countries is considered a failure. The Asian success stories often refer to the developmental state model, which highlights the pivotal role played by Asian political elites in catalyzing economic growth and broad-based development. The model includes economic liberalization and outward-oriented policies, with targeted support to – and protection of – strategic sectors and infant industries.How far is this underlying assumption supported by empirical evidence? This working paper examines a wide range of economic, social, institutional and governance indicators for a sample of six sub-Saharan and five South East Asian countries. Contrary to our research hypothesis, we did not find any significant difference in the level of government involvement in the domestic economy between the countries of the two regions, nor in the quality of institutions and governance indicators, nor in the share of imports and exports in GDP.Even if there are important gaps between the two regions, for instance with regard to the demographic transition, the agricultural sector or tertiary education, the picture is much more nuanced than portrayed by the dominant discourse. Our review of economic and socio-political indicators tells a rather different story, but not the whole story. Nevertheless, the indicators fail to take into account all the historical, institutional and structural factors that matter a great deal for development. Hence our analysis should be complemented by detailed country case studies to uncover the specific dynamics underlying different development trajectories and outcomes.

  6. Development and foreign debt: The stylized facts 1970-2006

    DEFF Research Database (Denmark)

    Paldam, Martin

    2008-01-01

    The paper uses the data from the incomplete debt cycle for the LDC world from 1970 onwards to tell the typical story of debt. Two debt stories are contrasted: A good debt story: Here countries borrow and invest wisely, so that they grow more. A bad debt story: Here countries borrow when they are in crisis, and the debt grows and generates low growth in the next couple of decades. The analysis concentrates on two relations: (R1) the relation between borrowing and growth, and (R2) the relation between initial debt and growth. Both relations are negative, so essentially the stylized story of debt is a story of bad debt. The paper looks in vain for non-linearities in the two relations, suggesting that the good debt story applies in some part of the range. The result thus confirms that international transfers to governments are an inefficient way to promote development.

  10. JWST Mirror Technology Development

    Science.gov (United States)

    Stahl, Philip H.

    2010-01-01

    Since the initial Design Studies leading to JWST, Mirror Technology was identified as a (if not the) critical capability necessary to enable the next generation of large aperture space telescopes required to achieve the science goals of imaging the earliest galaxies and proto-galaxies after the big bang. Specific telescope architectures were explored via three independent design concept studies conducted during the summer of 1996. Achieving the desired science objectives required a never before demonstrated space telescope capability, one with an 8 meter class primary mirror that is diffraction limited at 2 micrometers and operating in deep space at temperatures well below 70K. Beryllium was identified in the NASA "Yardstick" design as the preferred material because of its ability to provide stable optical performance in the anticipated thermal environment as well as its excellent specific stiffness. Because of launch vehicle constraints, two very significant architectural constraints were placed upon the telescope: segmentation and areal density. Each of these directly resulted in specific technology capability requirements. First, because the maximum launch vehicle payload fairing diameter is approximately 4.5 meters, the only way to launch an 8 meter class mirror is to segment it, fold it and deploy it on orbit - resulting in actuation and control requirements. Second, because of launch vehicle mass limits, the primary mirror allocation was only 1000 kg - resulting in a maximum areal density specification of 20 kilograms per square meter.

  11. Development of FR construction cost estimation method in FaCT project

    International Nuclear Information System (INIS)

    An economic competitiveness is crucial issue for FR. Within the FaCT project, commodities shall be reduced by introducing innovative technologies. In order to evaluate the economy for the Japan Sodium-cooled Fast Reactor (JSFR), we have been developing the account code named the SCALLE (Sum of Cost Account Leading to future Logistics Economy), in which the basic methodology is bottom up of component costs based on amounts of material and corresponding unit costs. Amount of material is evaluated based on the JSFR design. Unit costs are derived from the value of public documents about FR and LWR design mainly based on the Energy Economic Data Base of U.S. DOE. Cost evaluation accounts are classified considering JSFR system configuration. Estimated results by the SCALLE code for the past demonstration plant designed in Japan and the JSFR compared with results by our prior code and have a few % difference. As an example of construction cost estimation by the SCALLE code at current state, the ratio of NOAK cost is 74% of FOAK cost. The SCALLE code is still under developing for practical use from the view point of code validation and verification. (author)

    International Nuclear Information System (INIS)

    The Office of Technology Development (TD) supports research and development of technologies that will lower cost, reduce risk, improve safety, and accelerate cleanup of the Nuclear Weapons Complex and provide solutions to currently untractable environmental problems. The TD strategic plan outlines Applied Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) that will provide needed technology products to be used by Environmental Restoration and Waste Management operations (i.e., our customers). The TD strategic plan is derived from EM Goals, Objectives, and Strategy and is incorporated into DOE'S Five-Year Plan for Environmental Restoration and Waste Management. The TD strategic plan is developed based on integrating customer requirements, and is complemented by a top-down, bottom-up analysis of Site Specific Technology Needs and environmental problems. The execution of TD's strategic plan is implemented largely through Integrated Programs (IP) and Integrated Demonstrations (ID). IDs have proven to be a cost-effective method of managing technology development, testing and evaluation, and implementation of successful technology systems into the DOE Environmental Restoration and Waste Management Programs. The Savannah River ID for Volatile Organic Compounds (VOCs) in Saturated Soils resulted in a 51 percent cost savings over stand-alone demonstrations, saving over $8 million. The IPs and IDs are selected based on customer needs, technical complexitsed on customer needs, technical complexity, and complex-wide regulatory and compliance agreements. New technology systems are selected for incorporation into an IP or ID from offerings of the DOE laboratories, industry, and the universities. A major TD initiative was announced in August 1991, with the release of a Program Research and Development Announcement (PRDA) requesting industry and universities to propose innovative new technologies to clean up the Weapons Complex.

    2014-01-01

    Many marine fish stocks are overexploited and considerable overcapacity exists in fishing fleets worldwide. One of the reasons for the imbalance between resource availability and fishing capacity is technological development, which continuously increases the efficiency of the vessels—a mechanism referred to as “technological creep.” We review how the introduction of new and more efficient electronic equipment, gear design, engines, deck equipment, and catch-handling procedures influences the capture efficiency (catchability) of commercial fishing vessels. On average, we estimate that catchability increases by 3.2% per year due to technological developments, an increase often ignored in fisheries management. The documentation and quantification of technological creep improves the basis for successfully integrating the effects of technological development (and catchability changes) in fisheries management regulations and policies. Ways of counteracting the undesired effects of technological creep are discussed as are the potential management benefits from improved fishing technology. Specific suggestions are given on the selection, application, and tuning of fisheries management tools that can be used to improve the balance between harvesting capacity and resource availability

  18. Multichip module technology development

    International Nuclear Information System (INIS)

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). A Multichip Module (MCM) was designed and submitted for fabrication to the Lockheed Martin foundry using a licensed process called High Density Interconnect (HDI). The HDI process uses thin film techniques to create circuit interconnect patterns on multiple layers of dielectric film which are deposited directly on top of unpackaged electronic die. This results in an optimally small package that approaches the area of the bare die themselves. This project tested the capability of the Lockheed Martin foundry to produce, in an HDI process, a complex mixed-mode (analog and digital) circuit on a single MCM substrate

    2015-05-01

    The current longitudinal study tried to capture profiles of individual differences in children's arithmetic fact development. We used a model-based clustering approach to delineate profiles of arithmetic fact development based on empirically derived differences in parameters of arithmetic fact mastery repeatedly assessed at the start of three subsequent school years: third, fourth, and fifth grades. This cluster analysis revealed three profiles in a random sample-slow and variable (n = 8), average (n = 24), and efficient (n = 20)-that were marked by differences in children's development in arithmetic fact mastery from third grade to fifth grade. These profiles did not differ in terms of age, sex, socioeconomic status, or intellectual ability. In addition, we explored whether these profiles varied in cognitive skills that have been associated with individual differences in single-digit arithmetic. The three profiles differed in nonsymbolic and symbolic numerical magnitude processing as well as phonological processing, but not in digit naming or working memory. After also controlling for cluster differences in general mathematics achievement and reading ability, only differences in symbolic numerical magnitude processing remained significant. Taken together, our longitudinal data reveal that symbolic numerical magnitude processing represents an important variable that contributes to individual variability in children's acquisition of arithmetic facts.

  8. Development of radioisotope tracer technology

    International Nuclear Information System (INIS)

    The purpose of this study is to develop the radioisotope tracer technology, which can be used in solving industrial and environmental problems and to build a strong tracer group to support the local industries. In relation to the tracer technology in 1999, experiments to estimate the efficiencies of a sludge digester of a waste water treatment plant and a submerged biological reactor of a dye industry were conducted. As a result, the tracer technology for optimization of facilities related to wastewater treatment has been developed and is believed to contribute to improve their operation efficiency. The quantification of the experimental result was attempted to improve the confidence of tracer technology by ECRIN program which basically uses the MCNP simulation principle. Using thin layer activation technique, wear of tappet shim was estimated. Thin layer surface of a tappet shim was irradiated by proton beam and the correlation between the measured activity loss and the amount of wear was established. The equipment was developed to adjust the energy of proton which collides with the surface of tappet. The tracer project team has participated into the tracer test for estimating the efficiency of RFCC system in SK cooperation. From the experiment the tracer team has obtained the primary elements to be considered for judging the efficiency of RFCC unit. By developing the tracer techniques to test huge industrial units like RFCC, the tracer team will be able to support the local industries that require technical services to solve any urgent trouble.

    The Clean Coal Technology Demonstration Program (CCT Program), a model of government and industry cooperation, responds to the Department of Energy's (DOE) mission to foster a secure and reliable energy system that is environmentally and economically sustainable. The CCT Program represents an investment of over $5.2 billion in advanced coal-based technology, with industry and state governments providing an unprecedented 66 percent of the funding. With 26 of the 38 active projects having completed operations, the CCT Program has yielded clean coal technologies (CCTs) that are capable of meeting existing and emerging environmental regulations and competing in a deregulated electric power marketplace. The CCT Program is providing a portfolio of technologies that will assure that U.S. recoverable coal reserves of 274 billion tons can continue to supply the nation's energy needs economically and in an environmentally sound manner. As the nation embarks on a new millennium, many of the clean coal technologies have realized commercial application. Industry stands ready to respond to the energy and environmental demands of the 21st century, both domestically and internationally, For existing power plants, there are cost-effective environmental control devices to control sulfur dioxide (S02), nitrogen oxides (NO,), and particulate matter (PM). Also ready is a new generation of technologies that can produce electricity and other commodities, such as steam and synthetic gas, and provide efficiencies and environmental performance responsive to global climate change concerns. The CCT Program took a pollution prevention approach as well, demonstrating technologies that remove pollutants or their precursors from coal-based fuels before combustion. Finally, new technologies were introduced into the major coal-based industries, such as steel production, to enhance environmental performance. Thanks in part to the CCT Program, coal--abundant, secure, and economical--can continue in its role as a key component in the U.S. and world energy markets. The CCT Program also has global importance in providing clean, efficient coal-based technology to a burgeoning energy market in developing countries largely dependent on coal. Based on 1997 data, world energy consumption is expected to increase 60 percent by 2020, with almost half of the energy increment occurring in developing Asia (including China and India). By 2020, energy consumption in developing Asia is projected to surpass consumption in North America. The energy form contributing most to the growth is electricity, as developing Asia establishes its energy infrastructure. Coal, the predominant indigenous fuel, in that region will be the fuel of choice in electricity production. The CCTs offer a means to mitigate potential environmental problems associated with unprecedented energy growth, and to enhance the U.S. economy through foreign equipment sales and engineering services.

  13. Clean Coal Technology Demonstration Program: Project fact sheets 2000, status as of June 30, 2000

    International Nuclear Information System (INIS)

    The Clean Coal Technology Demonstration Program (CCT Program), a model of government and industry cooperation, responds to the Department of Energy's (DOE) mission to foster a secure and reliable energy system that is environmentally and economically sustainable. The CCT Program represents an investment of over$5.2 billion in advanced coal-based technology, with industry and state governments providing an unprecedented 66 percent of the funding. With 26 of the 38 active projects having completed operations, the CCT Program has yielded clean coal technologies (CCTs) that are capable of meeting existing and emerging environmental regulations and competing in a deregulated electric power marketplace. The CCT Program is providing a portfolio of technologies that will assure that U.S. recoverable coal reserves of 274 billion tons can continue to supply the nation's energy needs economically and in an environmentally sound manner. As the nation embarks on a new millennium, many of the clean coal technologies have realized commercial application. Industry stands ready to respond to the energy and environmental demands of the 21st century, both domestically and internationally, For existing power plants, there are cost-effective environmental control devices to control sulfur dioxide (S02), nitrogen oxides (NO,), and particulate matter (PM). Also ready is a new generation of technologies that can produce electricity and other commodities, such as steam and synthetic gas, and ies, such as steam and synthetic gas, and provide efficiencies and environmental performance responsive to global climate change concerns. The CCT Program took a pollution prevention approach as well, demonstrating technologies that remove pollutants or their precursors from coal-based fuels before combustion. Finally, new technologies were introduced into the major coal-based industries, such as steel production, to enhance environmental performance. Thanks in part to the CCT Program, coal-abundant, secure, and economical-can continue in its role as a key component in the U.S. and world energy markets.

  14. competitive technologies for sustainable development

    International Nuclear Information System (INIS)

    By letter dated 27 April 2011, the Director General of the Centre for Strategic Analysis, Vincent Chriqui, confided to Jean Bergougnoux, honorary president of the SNCF, Honorary General Director of EDF, the task of animating a reflection Prospective Technological Studies of the sectors of energy, transport and construction. This synthesis report, prepared with the assistance of rapporteurs Centre for Strategic Analysis, attempts to summarize and put into perspective all the work which show these specific reports. Admittedly some very complex issues still need supplements. It may therefore be useful to extend this work in a number of areas. Beyond its role in the competitiveness of a country, technological innovation is essential to provide appropriate responses to the challenges of our commitment to sustainable development in terms of economic growth, preservation of the environmental and social progress. Mission for Prospective Technological conducted by the Centre for Strategic Analysis has sought to clarify this dual problem by proposing a long-term vision for the energy, transport and construction. For each technology studied, it has attempted to assess both the possible contribution to sustainable development and the competitive potential of our country on the international scene. His work, chaired by Jean Bergougnoux have reviewed the technological advances that may occur in the coming decades in the sectors concerned. They examined the conditions for integration of these advances in systems and subsystems existing (or create) and the conditions of a mature technical, economic but also social. Wherever possible, two time horizons were identified: a medium-term horizon, 2030, for which we have a fairly clear vision of future developments and long-term horizon, 2050, which allows to consider jumps Scientists are still uncertain. Finally, the mission is interested in four transverse technologies involved consistently in the three study areas, which are likely to produce decisive progress (metrology, nano-technology, regulation and control command, the home network ). One of the lessons of the exercise is that technology foresight in France remains very crumbled, making it difficult both a systemic approach and yet essential, regarding the proper use of this scarce resource are public funds, prioritization on solid foundations. In each discipline in each sector, researchers, manufacturers have their own vision of the future, may be too optimistic for the first, but these visions fit poorly in a coherent framework to assess the real value of innovations possible. Set around a table specialists in different areas as we have done is both complex and constructive, but this exercise requires a prior rigorous methodological work to deepen and renew periodically knowledge. A practical difficulty in conducting a prospective overall is the lack of validated databases and shared the cost and performance of technologies. This applies both to the current state of various technologies for information - at least the orders of magnitude - about innovations in development or testing. These data exist or may exist, if the request was unclear, but they are scattered in many organizations and assume a coherence sufficient to serve as a basis for a prospective approach. The four proposals in the report: - Proposal No. 1: take into account the definition of mechanisms to support the development of technology, technical and economic maturity, their ability to integrate into existing systems and global positioning research and Industry French. - Proposal No. 2: In the area of electricity generation, encourage the deployment of renewable energy and competitive focus for those whose cost of electricity production would be above a threshold to be determined, and demonstration operations research. - Proposal No. 3: Given the price differences between the ground and photovoltaic roof, extend the concept of positive energy building a broader, island or district, to benefit local energy lower cost. - Proposal No. 4: Investing in the transverse tech

  15. Advanced Modular Inverter Technology Development

    2006-02-04

    Electric and hybrid-electric vehicle systems require an inverter to convert the direct current (DC) output of the energy generation/storage system (engine, fuel cells, or batteries) to the alternating current (AC) that vehicle propulsion motors use. Vehicle support systems, such as lights and air conditioning, also use the inverter AC output. Distributed energy systems require an inverter to provide the high quality AC output that energy system customers demand. Today's inverters are expensive due to the cost of the power electronics components, and system designers must also tailor the inverter for individual applications. Thus, the benefits of mass production are not available, resulting in high initial procurement costs as well as high inverter maintenance and repair costs. Electricore, Inc. (www.electricore.org) a public good 501 (c) (3) not-for-profit advanced technology development consortium assembled a highly qualified team consisting of AeroVironment Inc. (www.aerovironment.com) and Delphi Automotive Systems LLC (Delphi), (www.delphi.com), as equal tiered technical leads, to develop an advanced, modular construction, inverter packaging technology that will offer a 30% cost reduction over conventional designs adding to the development of energy conversion technologies for crosscutting applications in the building, industry, transportation, and utility sectors. The proposed inverter allows for a reduction of weight and size of power electronics in the above-mentioned sectors and is scalable over the range of 15 to 500kW. The main objective of this program was to optimize existing AeroVironment inverter technology to improve power density, reliability and producibility as well as develop new topology to reduce line filter size. The newly developed inverter design will be used in automotive and distribution generation applications. In the first part of this program the high-density power stages were redesigned, optimized and fabricated. One of the main tasks was to design and validate new gate drive circuits to provide the capability of high temp operation. The new power stages and controls were later validated through extensive performance, durability and environmental tests. To further validate the design, two power stages and controls were integrated into a grid-tied load bank test fixture, a real application for field-testing. This fixture was designed to test motor drives with PWM output up to 50kW. In the second part of this program the new control topology based on sub-phases control and interphase transformer technology was successfully developed and validated. The main advantage of this technology is to reduce magnetic mass, loss and current ripple. This report summarizes the results of the advanced modular inverter technology development and details: (1) Power stage development and fabrication (2) Power stage validation testing (3) Grid-tied test fixture fabrication and initial testing (4) Interphase transformer technology development

    Recent evidence on the respective contributions of institutions and trade to income levels across countries has demonstrated that - once endogeneity is considered - institutional quality clearly dominates the effect of trade. We argue that overall trade is not the most appropriate measure for technology diffusion as a source of productivity growth and propose to focus on imports of research and development (R&D) intensive goods instead. Overall, we confirm previous findings that institutions ...

  20. The gas turbine: Present technology and future developments

    International Nuclear Information System (INIS)

    The gas turbine is the most widely used prime mover all over the world for either power generation or mechanical drive applications. The above fact is due to the recent great improvements that have been done especially in terms of efficiency, availability and reliability. The future for gas turbine technological development looks very promising. In fact, although tremendous growth has already taken place, there is still the potential for dramatic improvements in performance. Compared with the competitive prime movers (conventional steam power plants and reciprocating piston engines) the gas turbine technology is younger and still following a strong growth curve. The coming decades will witness the continued increasing in turbine inlet temperature, the development of new materials and refrigeration systems and the commercialization of inter cooled system and steam cooled turbines. With the very soon introduction of the G and H technology, expected single and combined cycle efficiencies for heavy duty machines are respectively 40% and 60%, while maintaining 'single digit' levels in pollutant emissions. In this report are given wide information on gas turbine present technology (Thermodynamics, features, design, performances, emission control, applications) and are discussed the main lines for the future developments. Finally are presented the research and technological development activities on gas turbine of Italian National Agency for new Technology Energy and the Environment Energy Department

    The Wireless Power Transmission (WPT) technology has been treated to a wide extent in the recent years. A broad variety of applications has been investigated, from earth to orbit, orbit to earth, in-orbit and planetary ones, as for moon and Mars missions. In this course the question to use laser or microwave technology has widely been discussed. Beaming energy to spacecrafts could provide an important space mission-economic potential. It promises significant reduction in the cost of access to space, for scientific and commercial missions, and increases the mission capabilities for in-space systems. For the future enhancement of ISS capabilities and operational efficiency, the use of WPT technology became part of the technology research planning for the ISS. The WPT may have the potential of providing operational benefits, increase of spacecraft systems efficiency for elements like co-orbiting platforms, transfer vehicles or other ISS related in-orbit spacecrafts, and planetary exploration vehicles. The laser technology provides specific technical, operational and economic benefits compared to microwave applications and provides the actual basis for the envisioned wireless power transmission concepts. An outlook in terms of future wireless power perspectives, both for terrestrial as for space-to-space scenarios is given; these applications are part of a technology demonstration roadmap for wireless power transmission key- and supporting technologies, which is characterized by dedicated technology demonstration milestones on ground and in space. The actual technology development philosophy as conceived at EADS-Space Transportation is described and includes main system demonstration missions, as a laboratory test bed employing a small rover system, a scaled airship model demonstration as planned in 2004 and an experiment onboard the International Space Station ISS. These demonstrations represent milestones in terms of technical capability verification on the way to solar power platforms in space, as an actual Solar Power Platform Design Concept in the 400 kW range for GEO including the receiver side on ground. Special attention is given to the fact, that technological spin-offs out of the Solar Power Platforms development are an essential aspect of the activities. The application of the suitable type of laser systems for future solar power concepts in space will be discussed, based on recent investigations in the frame of the EADS technology development work. The experimental application of a laser system for power transmission to a moveable and steerable target, a small rover, is addressed also and the demonstration philosophy and experimental set-up are detailed. The ground test objectives, the definition, design and performance of a "Wireless Power Transmission" system and the demonstration of the basic principles of power transmission and target acquisition, pointing and tracking are covered. The lessons learned and consequences for a continuation of this type of demonstration are outlined.

    International Nuclear Information System (INIS)

    The objectives of this study are to develop the technology for the determination of isotopic ratios of nuclear particles detected from swipe samples and to develop the NIPS system. The R and D contents and results of this study are firstly the production of nuclear micro particle(1 ? 20 ?m) and standardization, the examination of variation in fission track characteristic according to nuclear particle size and enrichment(235U: 1-50%), the construction of database and the application of this technique to swipe samples. If this technique is verified its superiority by various field tests and inter-laboratory comparison program with other institutes in developed countries, it can be possible to join NWAL supervised under IAEA and to export our technology abroad. Secondly, characteristics of alpha track by boron (n, ?) nuclear reaction were studied to measure both total boron concentration and 10B enrichment. The correlation of number of alpha tracks and various 10B concentration was studied to evaluate the reliability of this method. Especially, cadmium shielding technique was introduced to reduce the background of alpha tracks by covering the solid track detector and the multi-dot detector plate was developed to increase the reproducibility of measurement by making boron solution dried evenly in the plate. The results of the alpha track method were found to be well agreed with those of mass spectroscopy within less than 10 % deviation. Finally, the NIPS system using 252Cf neutron source was developed and prompt gamma spectrum and its background were obtained. Monte Carlo method using MCNP-4B code was utilized for the interpretation of neutron and gamma-ray shielding condition as well as the moderation of a fast neutron. Gamma-gamma coincidence was introduced to reduce the prompt gamma background. The counting efficiency of the HPGe detector was calibrated in the energy range from 50 keV to 10 MeV using radio isotope standards and prompt gamma rays of Cl for the quantitative elemental analysis of aqueous sample. Several solid material was also examined with the NIPS system to apply this technology to diverse industry fields such as the identification of explosives or chemical warfares

    Uno, Kimio

    The economic and demographic growth in Asia has put increased importance to this part of the world whose contribution to the global community is vital in meeting global challenges. International cooperation in engineering education assumes a pivotal role in providing access to the frontiers of scientific and technological knowledge to the growing youths in the region. The thrust for advancement has been provided by the logic coming from the academic world itself, whereas expectations are high that the engineering education responds to challenges that are coming from outside the universities, such as environmental management, disaster management, and provision of common knowledge platform across disciplinary lines. Some cases are introduced in curriculum development that incorporates fieldwork and laboratory work intended to enhance the ability to cooperate. The new mode is discussed with focus on production, screening, storing/delivery, and leaning phases of knowledge. The strength of shared information will be enhanced through international cooperation.

    After consideration of a likely timetable for the development of a synthetic fuels industry and its necessary supporting technology, the large variety of such fuels and their potential roles is assessed along with their commercialization outlook. Among the fuel production methods considered are: (1) above-ground retorting of oil shale; (2) in-situ shale retorting; (3) open pit mining of tar sands; (4) in-situ steam stimulation of tar sands; (5) coal gasification; (6) methanol synthesis from carbon monoxide and hydrogen; and (7) direct coal liquefaction by the hydrogenation of coal. It is shown that while the U.S. has very limited resource bases for tar sands and heavy crudes, the abundance of shale in the western states and the abundance and greater geographical dispersion of coal will make these the two most important resources of a future synthetic fuels industry.

    The Arctic Energy Technology Development Laboratory was created by the University of Alaska Fairbanks in response to a congressionally mandated funding opportunity through the U.S. Department of Energy (DOE), specifically to encourage research partnerships between the university, the Alaskan energy industry, and the DOE. The enabling legislation permitted research in a broad variety of topics particularly of interest to Alaska, including providing more efficient and economical electrical power generation in rural villages, as well as research in coal, oil, and gas. The contract was managed as a cooperative research agreement, with active project monitoring and management from the DOE. In the eight years of this partnership, approximately 30 projects were funded and completed. These projects, which were selected using an industry panel of Alaskan energy industry engineers and managers, cover a wide range of topics, such as diesel engine efficiency, fuel cells, coal combustion, methane gas hydrates, heavy oil recovery, and water issues associated with ice road construction in the oil fields of the North Slope. Each project was managed as a separate DOE contract, and the final technical report for each completed project is included with this final report. The intent of this process was to address the energy research needs of Alaska and to develop research capability at the university. As such, the intent from the beginning of this process was to encourage development of partnerships and skills that would permit a transition to direct competitive funding opportunities managed from funding sources. This project has succeeded at both the individual project level and at the institutional development level, as many of the researchers at the university are currently submitting proposals to funding agencies, with some success.

  1. Nuclear technology in developing countries

    International Nuclear Information System (INIS)

    Three decades ago India started the nuclear power programme. A decision was taken to pursue a programme of indigenous development of nuclear power technology. The first nuclear power station was set up in 1969 at Tarapur. A proven reactor system was imported for this plant in order to gain time as well as experience in operation and maintenance of nuclear power stations. The pressurised heavy water reactor system was chosen for the subsequent nuclear power stations for efficient utilization of natural uranium resources in the country. This choice has helped in the pursuit of the ultimate indigenous capability. At present the installed nuclear power capacity is 1230 MWe and it is planned to reach an installed nuclear power capacity of 10,000 MWe by the end of this century. It will be about 10% of the total power generated in the country. In the past three decades India has developed capability for the design, manufacture, construction, commissioning and operation of the nuclear power reactors. (orig.)

  2. Cooperative technology development: An approach to advancing energy technology

    International Nuclear Information System (INIS)

    Technology development requires an enormous financial investment over a long period of time. Scarce national and corporate resources, the result of highly competitive markets, decreased profit margins, wide currency fluctuations, and growing debt, often preclude continuous development of energy technology by single entities, i.e., corporations, institutions, or nations. Although the energy needs of the developed world are generally being met by existing institutions, it is becoming increasingly clear that existing capital formation and technology transfer structures have failed to aid developing nations in meeting their growing electricity needs. This paper will describe a method for meeting the electricity needs of the developing world through technology transfer and international cooperative technology development. The role of nuclear power and the advanced passive plant design will be discussed. (author)

This paper provides a theoretical and conceptual framework analysis for managing innovation and technology in developing countries like India and China. We present the issues and challenges in innovation and technology management and come up with pro...

  5. Policy issues inherent in advanced technology development

    International Nuclear Information System (INIS)

    In the development of advanced technologies, there are several forces which are involved in the success of the development of those technologies. In the overall development of new technologies, a sufficient number of these forces must be present and working in order to have a successful opportunity at developing, introducing and integrating into the marketplace a new technology. This paper discusses some of these forces and how they enter into the equation for success in advanced technology research, development, demonstration, commercialization and deployment. This paper limits itself to programs which are generally governmental funded, which in essence represent most of the technology development efforts that provide defense, energy and environmental technological products. Along with the identification of these forces are some suggestions as to how changes may be brought about to better ensure success in a long term to attempt to minimize time and financial losses

    1977-05-11

    This report is a compendium of facts related to chemical materials present in industrial waste process streams which have already been declared or are being evaluated as hazardous under the Toxic Substances Control Act. Since some 400 chemicals are presently covered by consensus standards, the substances reviewed are only those considered to be a major threat to public health and welfare by Federal and State regulatory agencies. For each hazardous material cited, the facts relate, where possible, to an identification of the stationary industrial sources, the kind of waste stream impacted, proposed regulations and established effluent standards, the volume of emissions produced each year, the volume of emissions per unit of industrial product produced, present clean-up capabilities, limitations, and costs. These data should be helpful in providing information for the assessment of potential problems, should be of use to the manufacturers of pollution control equipment or of chemicals for pollution control, should be of use to the operators or potential operators of processes which produce pollutants, and should help to define industry-wide emission practices and magnitudes.

  15. Electronic Submersible Pump (ESP) Technology and Limitations with Respect to Geothermal Systems (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2014-09-01

    The current state of geothermal technology has limitations that hinder the expansion of utility scale power. One limitation that has been discussed by the current industry is the limitation of Electric Submersible Pump (ESP) technology. With the exception of a few geothermal fields artificial lift technology is dominated by line shaft pump (LSP) technology. LSP's utilize a pump near or below reservoir depth, which is attached to a power shaft that is attached to a motor above ground. The primary difference between an LSP and an ESP is that an ESP motor is attached directly to the pump which eliminates the power shaft. This configuration requires that the motor is submersed in the geothermal resource. ESP technology is widely used in oil production. However, the operating conditions in an oil field vary significantly from a geothermal system. One of the most notable differences when discussing artificial lift is that geothermal systems operate at significantly higher flow rates and with the potential addition of Enhanced Geothermal Systems (EGS) even greater depths. The depths and flow rates associated with geothermal systems require extreme horsepower ratings. Geothermal systems also operate in a variety of conditions including but not limited to; high temperature, high salinity, high concentrations of total dissolved solids (TDS), and non-condensable gases.

    Nuclear technology development in Japan has been carried out based on the Atomic Energy Basic Act brought into effect in 1955. The nuclear technology development is limited to peaceful purposes and made in a principle to assure their safety. Now, the technologies for research reactors radiation application and nuclear power plants are delivered to developing countries. First of all, safety measures of nuclear power plants (NPPs) will be enhanced based on lesson learned from TEPCO Fukushima Daiichi NPS accident.

  2. Research and development policy on FBR cycle technology in Japan

    International Nuclear Information System (INIS)

    The Fast Breeder Reactor (FBR) and its fuel cycle (hereinafter 'FBR cycle') technology will provide harmonic solutions for global energy resource and environment issues.In Japan, the significance of FBR cycle technology development has been recognized for decades. The Japan Atomic Energy Agency (JAEA) has been the principal agency for the FBR cycle development in Japan. The experimental fast reactor, Joyo, had been successfully operated for about 30 years, beginning in 1977. The prototype FBR, Monju, achieved initial criticality in 1994. Monju is designed on the basis of research results gleaned from Joyo. Monju has the role of confirming the technological data base for design and safety evaluation tools, and of accumulating operation experiences for sodium-cooled reactors, with an eye toward commercialization. Both reactors' operations have been suspended since 2007 and 1995, respectively, due to troubles; presently, JAEA is preparing for the re-launch of operations. Furthermore, the development of FBR spent fuel reprocessing technologies was initiated in 1975, and JAEA has successfully achieved MOX fuel fabrication at the Plutonium Fuel Center, as far back as 1972. In 1999, the 'Feasibility Study on Commercialized FBR Cycle Systems (FS)' was initiated to present an appropriate picture of FBR cycle technology commercialization by 2015, as well as its research and development (R and D) program. In this study, conceptual design features were evaluated in order to selec features were evaluated in order to select promising FBR cycle systems that could meet the design requirements that embodied the five development targets: 1) safety; 2) economic competitiveness; 3) efficient utilization of nuclear fuel resources; 4) reduction of environmental burden; and 5) enhancement of nuclear non-proliferation. As a result, the combination of sodium-cooled FBR with oxide fuel, advanced aqueous reprocessing and simplified pelletizing fuel fabrication was selected as the most promising concept for the FBR cycle system. Figure 1 shows major features of the Japanese sodium-cooled FBR. The Atomic Energy Commission of Japan (AECJ) issued the 'Framework of Nuclear Energy Policy' in October of 2005, which is the foundation of Japanese policy on research, development,and utilization of nuclear energy. In this framework, the target for development of FBR cycle technology is commercialization by y approximately 2050. In March of 2006, FBR cycle technology was selected as one of the key technologies of national importance in the third-term 'Science and Technology Basic Plan.' Subsequently, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Economy, Trade and Industry (METI) formulated the action plan f f for the development of nuclear technologies to materialize the framework reviewing the report of FS. Following the action plan, the council of five-parties, which consisted of MEXT, METI, the Federation of Electric Power Companies of Japan (FEPC), the Japan Electrical Manufacturer's Association (JEMA) and JAEA, was set up to discuss the smooth transition from the R and D stage to the demonstration and deployment stages, in the process developing a solid mutual understanding of the issues. The 'Basic Energy Plan,' issued in March of 2007, explains that the FBR cycle development should be promoted as one of the most important technologies, with the aim to commercialize the FBR cycle system by 2050. Following the Japanese policy on FBR cycle technology development, MEXT, METI and JAEA, launched the Fast Reactor Cycle Technology Development (FaCT) project in 2006, in cooperation with the Japanese electrical utilities. Figure2 shows an outline of the development plan toward commercialization of the FBR cycle technology in Japan. In the FaCT project, design and experimental study for the main concept will be implemented in order to present the conceptual designs of the commercial and demonstrative FBR cycle facilities by 2015, along with the development plan to realize them. R and D has progressed to the develop

    Polle, Juergen [Brooklyn College; Sanchez-Delgado, Roberto [Brooklyn College

    2013-12-30

    This project investigated technologies that may reduce environmental pollution. This was a basic research/educational project addressing two major areas: A. In the algae research project, newly isolated strains of microalgae were investigated for feedstock production to address the production of renewable fuels. An existing collection of microalgae was screened for lipid composition to determine strains with superior composition of biofuel molecules. As many microalgae store triacylglycerides in so-called oil bodies, selected candidate strains identified from the first screen that accumulate oil bodies were selected for further biochemical analysis, because almost nothing was known about the biochemistry of these oil bodies. Understanding sequestration of triacylglycerides in intracellular storage compartments is essential to developing better strains for achieving high oil productivities by microalgae. At the onset of the project there was almost no information available on how to obtain detailed profiles of lipids from strains of microalgae. Our research developed analytical methods to determine the lipid profiles of novel microalgal strains. The project was embedded into other ongoing microalgal projects in the Polle laboratory. The project benefited the public, because students were trained in cell cultivation and in the operation of state-of-the-art analytical equipment. In addition, students at Brooklyn College were introduced into the concept of a systems biology approach to study algal biofuels production. B. A series of new nanostructured catalysts were synthesized, and characterized by a variety of physical and chemical methods. Our catalyst design leads to active nanostructures comprising small metal particles in intimate contact with strongly basic sites provided by the supports, which include poly(4-vinylpyridine), magnesium oxide, functionalized multi-walled carbon nanotubes, and graphene oxide. The new materials display a good potential as catalysts for reactions of relevance to the manufacture of cleaner fossil fuels and biodiesel, and to hydrogen storage in organic liquids. Specifically the catalysts are highly active in the hydrogenation of aromatic and heteroaromatic components of fossil fuels, the reduction of unsaturated C=C bonds in biodiesel, and the dehydrogenation of nitrogen heterocycles. In the course of our studies we identified a novel dual-site substrate-dependent hydrogenation mechanism that explains the activity and selectivity data obtained and the resistance of the new catalysts to poisoning. These results represent an important advance in basic catalytic science, regarding design and synthesis and reaction mechanisms. Additionally, this project allowed the enhancement of the laboratory facilities in the Chemistry Department of Brooklyn College for catalysis and energy research, and served as an excellent vehicle for the training of several young researchers at the undergraduate, graduate and postdoctoral level, to join the national scientific workforce.

    The Lunar Surface Systems Supportability Technology Development Roadmap is a guide for developing the technologies needed to enable the supportable, sustainable, and affordable exploration of the Moon and other destinations beyond Earth. Supportability is defined in terms of space maintenance, repair, and related logistics. This report considers the supportability lessons learned from NASA and the Department of Defense. Lunar Outpost supportability needs are summarized, and a supportability technology strategy is established to make the transition from high logistics dependence to logistics independence. This strategy will enable flight crews to act effectively to respond to problems and exploit opportunities in an environment of extreme resource scarcity and isolation. The supportability roadmap defines the general technology selection criteria. Technologies are organized into three categories: diagnostics, test, and verification; maintenance and repair; and scavenge and recycle. Furthermore, "embedded technologies" and "process technologies" are used to designate distinct technology types with different development cycles. The roadmap examines the current technology readiness level and lays out a four-phase incremental development schedule with selection decision gates. The supportability technology roadmap is intended to develop technologies with the widest possible capability and utility while minimizing the impact on crew time and training and remaining within the time and cost constraints of the program.

  20. FaCT phase I evaluation on the advanced aqueous reprocessing process (5). Research and development of uranium crystallization system

    International Nuclear Information System (INIS)

    As a part of FaCT project, JAEA has been developing a U crystallization process for FBR fuel reprocessing in collaboration with MMC. The development targets were U recovery rate of over 70%, DFs of 102, confirmation of mechanical performance of crystallizer, and so on. Fundamental data were obtained by beaker-scale experiments with actual dissolver solution. U crystallization rate could be controlled by composition of feed solution and cooling temperature. DFs for most of the FPs are improved by washing. However the formation of Pu-Cs double salt causes low DF of Cs. To confirm the mechanical performance of an annular type crystallizer and a crystal separator, some experiments were carried out. The crystallizer and the separator have good performance. However washing of UNH crystals by the separator did not have the intended effect for solid impurities. We discussed the application of crystal purification technology to improve the purity and selected Kureha Crystal Purifier (KCP). To investigate the behavior of solid impurities in KCP, UNH crystal purification tests were carried out using bench-scale KCP apparatus with simulated solid impurities. The purifier has good performance on the decontamination of not only liquid impurities but also solid impurities. (author)

  1. Learning in renewable energy technology development

    International Nuclear Information System (INIS)

    The main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment costs and electricity production costs. Possible additional costs of intermittent renewable electricity sources (such as storage, backup-capacity or grid fortification) with advanced penetration are not investigated, although these issues may be important on the longer term (after 2020)

    Educational technology is facilitating new approaches to teaching and learning science, technology, engineering, and mathematics (STEM) education. Cognitive research is beginning to inform educators about how students learn providing a basis for design of more effective learning environments incorporating technology. At the same time, access to computers, the Internet and other technology tools are becoming common features in K-20 classrooms. Encouraged by these developments, STEM educators are transforming traditional STEM education into active learning environments that hold the promise of enhancing learning. This document illustrates the use of technology in STEM education today, identifies possible areas of development, links this development to the NASA Strategic Plan, and makes recommendations for the Kennedy Space Center (KSC) Education Office for consideration in the research, development, and design of new educational technologies and applications.

  4. Technology development for radiation shielding analysis

    International Nuclear Information System (INIS)

    Radiation shielding analysis in nuclear engineering fields is an important technology which is needed for the calculation of reactor shielding as well as radiation related safety problems in nuclear facilities. Moreover, the design technology required in high level radioactive waste management and disposal facilities is faced on serious problems with rapidly glowing nuclear industry development, and more advanced technology has to be developed for tomorrow. The main purpose of this study is therefore to build up the self supporting ability of technology development for the radiation shielding analysis in order to achieve successive development of nuclear industry. It is concluded that basic shielding calculations are possible to handle and analyze by using our current technology, but more advanced technology is still needed and has to be learned for the degree of accuracy in two-dimensional shielding calculation.

  5. Technology transfer in the Clean Development Mechanism

    International Nuclear Information System (INIS)

    Technology transfer is often mentioned as an ancillary benefit of the Kyoto Protocol's Clean Development Mechanism (CDM), but this claim has never been researched or substantiated. The question of technology transfer is important from two perspectives: for host countries, whether the CDM provides a corridor for foreign, climate-friendly technologies and investment, and for industrialised countries as it provides export potential for climate-friendly technologies developed as a consequence of stringent greenhouse gas targets. In order to better understand whether technology transfer from the EU and elsewhere is occurring through the CDM, and what is the value of the associated foreign investment, this paper examines technology transfer in the 63 CDM projects that were registered on January 1st, 2006. Technology originates from outside the host country in almost 50% of the evaluated projects. In the projects in which the technology originates from outside the host country, 80% use technology from the European Union. Technologies used in non-CO2 greenhouse gas and wind energy projects, and a substantial share of the hydropower projects, use technology from outside the host country, but biogas, agricultural and biomass projects mainly use local technology. The associated investment value with the CDM projects that transferred technology is estimated to be around 470 million Euros, with about 390 coming from the EU. As the non-CO2 greenhouse gas projects had very low capitgreenhouse gas projects had very low capital costs, the investment value was mostly in the more capital-intensive wind energy and hydropower projects

  13. Technology Development: From Idea to Implementation - 12131

    International Nuclear Information System (INIS)

    There are good ideas and new technologies proposed every day to solve problems within the DOE complex. A process to transition a new technology from inception to the decision to launch a project with baselines is described. Examples from active technology development projects within Savannah River Remediation (SRR) will be used to illustrate the points. The process includes decision points at key junctures leading to preliminary design. At that point, normal project management tools can be employed. The technology development steps include proof-of-principle testing, scaled testing and analysis, and conceptual design. Tools are used that define the scope necessary for each step of technology development. The tools include use of the DOE technology readiness guide, Consolidated Hazards Analysis (CHA) and internal checklists developed by Savannah River Remediation. Integration with operating or planned facilities is also included. The result is a roadmap and spreadsheet that identifies each open question and how it may be answered. Performance criteria are developed that enable simple decisions to be made after the completion of each step. Conceptual design tasks should begin as the technology development continues. The most important conceptual design tasks at this point in the process include process flow diagrams (PFDs), high level Process and Instrumentation Drawings (P and IDs), and general layout drawings. These should influence the design of the scaled simulant testing. Mechanical and electrical drawings that support cost and schedule development should also be developed. An early safety control strategy developed from the CHA will also influence the cost. The combination of test results, calculations and early design output with rough order of magnitude cost and schedule information provide input into the decisions to proceed with a project and data to establish the baseline. This process can be used to mature any new technology, especially those that must be integrated into complicated flow sheets. Then fully informed decisions can be made to usher technology development ideas through project implementation. Examples from active technology development projects, Tank 48 Treatment and Enhanced Chemical Cleaning, are presented. This model for technology development integrates several tools and activities to provide a logical method for maturing new ideas and technologies. It provides a framework to develop a good idea into a full up design/build project. This model defines a set of integrated tasks to mature the technology and define scope, cost and schedule necessary to make business decisions for implementing technology development. (authors)

  14. Technology Development Roadmaps - a Systematic Approach to Maturing Needed Technologies

    International Nuclear Information System (INIS)

    Planning and decision making represent important challenges for all projects. This paper presents the steps needed to assess technical readiness and determine the path forward to mature the technologies required for the Next Generation Nuclear Plant. A Technology Readiness Assessment is used to evaluate the required systems, subsystems, and components (SSC) comprising the desired plant architecture and assess the SSCs against established Technology Readiness Levels (TRLs). A validated TRL baseline is then established for the proposed physical design. Technology Development Roadmaps are generated to define the path forward and focus project research and development and engineering tasks on advancing the technologies to increasing levels of maturity. Tasks include modeling, testing, bench-scale demonstrations, pilot-scale demonstrations, and fully integrated prototype demonstrations. The roadmaps identify precise project objectives and requirements; create a consensus vision of project needs; provide a structured, defensible, decision-based project plan; and, minimize project costs and schedules.

  19. Technology development and applications at Fernald

    International Nuclear Information System (INIS)

    At the Fernald Environmental Management Project (FEMP) northwest of Cincinnati, Ohio, the U.S. Department of Energy and contractor Fernald Environmental Restoration Management Corporation (FERMCO) are aggressively pursuing both the development and the application of improved, innovative technology to the environmental restoration task. Application of emerging technologies is particularly challenging in a regulatory environment that places pressure on operational managers to develop and meet tight schedules. The regulatory and operational needs make close communication essential between technology developers and technology users (CERCLA/RCRA Unit managers). At Fernald this cooperation and communication has led, not only to the development and demonstration of new technologies with applications at other sites, but also to application of new technologies directly to the Fernald clean up. New technologies have been applied to improve environmental safety and health, improve the effectiveness of restoration efforts, and to cut restoration costs. The paper will describe successful efforts to develop and apply new technologies at the FEMP and will emphasize those technologies that have been applied and are planned for use in the clean up of this former uranium production facility

    Full Text Available The aim of the article. The aim of the article is to define and to estimate the forming of expediency of the development strategy of financial and innovative technologies in the context of modern economic space realities.The results of the analysis. The growing importance of the financial sector in the contemporary economic space, as well as rapid changes in it, generates a need for financial innovative technologies. Development strategy of financial and innovative technologies is always associated with the current state of the financial system, its existent technical, technological and financial base. Therefore, the strategy of financial and innovative technologies will be considered the system of long-term goals and means of achieving them, implemented in the financial activity. Financial innovative technologies strategy includes two aspects: 1 management of the introduction of technical and technological innovations; 2the process of constant changes in the financial sector according to the environment change. Thus, theessence of the development strategy of financial innovative technologies is to target business entities (including banks to application new and more efficient technologies, services and organizational structures. In other words, to put the problem of profitability, flexibility and adaptability increasing in the financial market.The development expediency of the financial and innovative technologies is determined by such criteria: concordance with the amount of capital that can be directed to the financial activity; efficiency or concordance of the results and the real costs of achieving them; distinctness in terms of achieving the aim; the optimal combination of expected achievement the necessary profitability and possible risks and uncertainty in the future period; concordance of planned financial technologies with general economic conditions of the environment. Choosing the basic strategy of financial innovative technologies should be conducted on a competition model of M. Porter, which intends to provide price leading strategy, differentiation strategy and concentration strategy. At the same time, the general strategy can be represented as a set of strategic and tactical development plans of financial innovative technologies.To implement the development strategy of financial innovative technologies into practice it is necessary to create special group of innovation introduction. Its main aim is to provide the plan of innovations and its main functions consist of the following:development and formation mechanism of implementation the financial innovative technologies, taking into account general aspects of financial planning;organization of operational implementation groups of separate financial innovative solutions and coordination of their work;encouragement liaison with independent experts and consultants to assess the implementation of innovative financial solutions;collecting and providing of objective information on the implementation of financial and innovative technologies to specialists and management.Conclusions and directions of further researches. An innovative type of financial development is formed in Ukraine today. The financial system is under constant change and evolution. Financial innovative technologies significantly effect on fluctuations of these processes. Application development strategy of financial innovative technologies will promote the improvement of general financial management for all economic subjects and broaden financial space of the country as a whole, as well as accelerate the introduction of new financial, informational and telecommunication technologies. However, based on the fact that economic subjects have not identical conditions of development, it is advisable to clarify the introduction sequence of new financial technologies, in other words identification of separate functional strategies of their promotion.

  3. Technological opportunities and paths of development

    DEFF Research Database (Denmark)

    Plichta, Kirsten

    1993-01-01

    Executive summary: 1) The technological development of firms in an industry is influenced by the opportunities for improving product and process, their ability to identify such opportunities and their ability to appropriate the benefit of the development effort. 2) Firms' historically developed technological knowledge, their production, development and other routines as well prior investments in products and production equipment play an important role with regard to the technological opportunities that firms' identify and select for development. 3) Because history matters and because firms are bounded rational they tend to choose opportunities for incremental improvements in their products and production techniques rather than developing radical new products and techniques. 4) Persistent differences between firms in an industry with regard to their products and process technologies are an outcome of the interplay between opportunities for improvement and differences in firms technological competencies and appropriation ability. 5) However, differences between firms in their technological development tend to narrow down to different ways of improving what has become a dominant product or production design in the industry. 6) It is argued that such paths of incremental improvement at the industry level may be an outcome of a) the dynamics that produce the technological opportunities; b) the institutions that govern decisions and expectations and c) the criteria by which the chooses between different firms technological development efforts. 7) The dynamic that produces opportunities for technological development will in part depend on characteristics of the product (e.g., its complexity), the interdependence between the product and production techniques, the diffusion of the product and in part on the accumulation of technological knowledge that makes possible the identification of new technological problems and solutions. These dynamics produce a limited and coh stream of opportunities once a dominant design has emerged in an industry. 8) The dominant design, reducing uncertainty in both the market and technology dimension, represented a more attractive line of development than developing alternative solutions. The dominant designs' position in an industry may also be strengthened by institutions such as technological communities and techno-economic paradigms. 9) Finally, the market selection between the outcome of different firms development effort may also help shape a path at the industry level. This may be because the criteria by which the market selects between the different product may to some extent be anticipated by the developing firms or because the criteria by which the market select betwee different solution may be such that only those solutions that represent incremental improvement in a dominant design will be chosen.

The principle behind Smart Living Technology is that technology should be used to advance the needs of human beings and to increase the quality of life by the power of human creativity while at the same time sustaining the environment for future generations. As such, intelligent networks should be adopted to provide humans with full information to control an individual’s personal environment. Wireless technology can play a key role in enabling smart energy monitoring by allowing consumers to make more informed choices and to connect products and devices to a coordinated management system. The development of Smart Living Technology is based on the concept of user driven innovations. Various Living Labs have been established around the world as development centers for extension of this Smart Living Technology. In this paper, the background and current developments of Smart Living Technology are reviewed, followed by real examples taking place in Taiwan. Finally, the focus and future plan for Taiwan are discussed including a strategy for further development of Smart Living Technology in Taiwan.

  12. Technology development and transfer in environmental management

    International Nuclear Information System (INIS)

    Federal efforts to develop and employ the innovative technologies needed to clean up contaminated facilities would greatly benefit from a greater degree of interaction and integration with the energies and resources of the private sector. Yet there are numerous institutional, economic, and regulatory obstacles to the transfer and commercialization of environmental restoration and waste management technologies. These obstacles discourage private sector involvement and investment in Federal efforts to develop and use innovative technologies. A further effect is to impede market development even where private sector interest is high. Lowering these market barriers will facilitate the commercialization of innovative environmental cleanup technologies and expedite the cleanup of contaminated Federal and private facilities. This paper identifies the major barriers to transfer and commercialization of innovative technologies and suggests possible strategies to overcome them. Emphasis is placed on issues particularly relevant to the Department of Energy's Environmental Restoration and Waste Management (EM) program, but which are applicable to other Federal agencies confronting complex environmental cleanup problems

  14. Normative discourse and technological development

    International Nuclear Information System (INIS)

    The intention of this book is to give - in connection with the nuclear energy controversy-reasons for the necessity to re-define the relationship of state and law to nuclear technology and to the decisive problems, and thus to search for possibilities of a legal control of nuclear technology. Ueberhorst appreciates these endeavours in this epilogue from the point of view of a parliamentarian and planner. Taking as a criterion an ideal-typical normative control - and regulation process he ascertains deficits of alternatives, value considerations, assessments of consequences, discourses, and control in the nuclear energy controversy which are not even recognized by legal practice and legal science. For, the performance of these neglected tasks in the 'not-yet-contributions' of the jurists and the law is hindered by the 'juridical fiction' that the Nuclear Energy Act is a sufficient answer of these questions. The jurists' task in the nuclear energy controversy should not be to dig trenches and to arm but they should feel obliged to the democratic-normative control of conflicts in the interest of the public.

  3. Clean coal technology development in China

    International Nuclear Information System (INIS)

    Coal is found in huge amounts throughout the world and is expected to play a crucial role as an abundant energy source. However, one critical issue in promoting coal utilization is controlling environmental pollution. Clean coal technologies are needed to utilize coal in an environmentally acceptable way and to improve coal utilization efficiency. This paper describes coal's role in China's energy system and the environmental issues related to coal use. Coal is responsible for 90% of the SO2 emissions, 70% of the dust emissions, 67% of the NOx emissions, and 70% of the CO2 emissions. But as the most abundant energy resource, it will continue to be the dominant energy supply for a long time. Therefore, the development and deployment of clean coal technologies are crucial to promote sustainable development in China. Clean coal technologies currently being developed in China are described including high efficiency combustion and advanced power generation technologies, coal transformation technologies, IGCC (integrated gasification combined cycle) and carbon capture and storage (CCS). Although China only recently began developing clean coal technologies, there have been many successes. Most recent orders of coal-fired power plants are units larger than 600 MW and new orders for supercritical and ultra supercritical systems are increasing rapidly. Many national research programs, industrial research programs and international collaboration programs and international collaboration projects have been launched to develop on IGCC and CCS systems in China. Finally, suggestions are given on how to further promote clean coal technologies in China.

    The pre-treatment and handling techniques for the micro-particles in swipe samples were developed for the safeguards purpose. The development of screening technique for the swipe samples has been established using the nuclear fission track method as well as the alpha track method. The laser ablation system to take a nuclear particle present in swipe was designed and constructed for the determination of the enrichment factors for uranium or plutonium, and its performance was tested in atmosphere as well as in vacuum. The optimum conditions for the synthesis of silica based micro-particles were obtained for mass production. The optimum ion exchange resin was selected and the optimum conditions for the uranium adsorption in resin bead technique were established for the development of the enrichment factor for nuclear particles in swipe. The established technique was applied to the swipe taken directly from the nuclear facility and also to the archive samples of IAEA's environmental swipes. The evaluation of dose rate of neutron and secondary gamma-ray for the radiation shields were carried out to design the NIPS system, as well as the evaluation of the thermal neutron concentration effect by the various reflectors. D-D neutron generator was introduced as a neutron source for the NIPS system to have more advantages such as easier control and moderation capability than the {sup 252}Cf source. Simulated samples for explosive and chemical warfare were prepared to construct a prompt gamma-ray database. Based on the constructed database, a computer program for the detection of illicit chemical and nuclear materials was developed using the MATLAB software.

In 1999, U.S. mining operations produced $66.7 billion worth of raw materials that contributed a total of $533 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Originally set up by Virginia Tech and West Virginia University, this endeavor has been expanded into a seven-university consortium--Virginia Tech, West Virginia University, University of Kentucky, University of Utah, Montana Tech, New Mexico Tech and University of Nevada, Reno--that is supported through U.S. DOE Cooperative Agreement No. DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation (2) Solid-liquid separation (3) Chemical/Biological Extraction (4) Modeling and Control, and (5) Environmental Control.

    The design, fabrication, testing, and analysis of stiffened wing cover panels to assess damage tolerance criteria are discussed. The damage tolerance improvements were demonstrated in a test program using full-sized cover panel subcomponents. The panels utilized a hard skin concept with identical laminates of 44-percent 0-degree, 44-percent plus or minus 45-degree, and 12-percent 90-degree plies in the skins and stiffeners. The panel skins were impacted at midbay between the stiffeners, directly over the stiffener, and over the stiffener flange edge. The stiffener blades were impacted laterally. Impact energy levels of 100 ft-lb and 200 ft-lb were used. NASTRAN finite-element analyses were performed to simulate the nonvisible damage that was detected in the panels by nondestructive inspection. A closed-form solution for generalized loading was developed to evaluate the peel stresses in the bonded structure. Two-dimensional delamination growth analysis was developed using the principle of minimum potential energy in terms of closed-form solution for critical strain. An analysis was conducted to determine the residual compressive stress in the panels after impact damage, and the analytical predictions were verified by compression testing of the damaged panels.

  4. Science and technology in a developing country: The Brazilian case

    International Nuclear Information System (INIS)

    Full text: This paper treats the development of science and technology in Brazil in a historical perspective within the Brazilian socio-economic context. The development of natural and human resources and the buildup of the Brazilian economy that have taken place over the last few decades are best described against the background of the well known economic cycles involving sugar production, gold mining and coffee cultivation, all largely based on slave labor until late in the 19th century. Brazilian industrialization has often been described as resulting from the adoption of an import substitution model. This paper claims that, alternatively, it may be described as a technology importation model. The implementation of this scheme demanded the rapid development of human capital which, in Brazil, has followed an original approach. In fact, traditional university education only started in the 1930s, higher education having taken root only in previously isolated high quality technical schools, such as mining, electrical engineering, agricultural engineering and, of course, the traditional institutions for teaching medicine and law. By the 1950s, largely under the influence of some outstanding scientists - mostly trained in the frontiers of nuclear sciences - the National Council of Research and the National Post-Graduate Training Programme were created. This has led, until now, to reasonable scientific, and to a lesser extent, technological development. The recent globalization process - the new economy - has broken down barriers to international commerce and required in recent years greater efforts to disseminate basic general education and the fostering of advanced science and technology. To this end, science and technology, along with research and development activities, have reached 1.35% and 0.9% of Brazil's GNP, respectively. Innovation as measured by patent applications has been modest. However, the technology balance has grown since the 1990s at a rate greater than 25% per year, reaching in 1999 US$ 3 billion for imports and US$ 1.35 billion for exports. In this context it is interesting to note that a recent UNDP study revealed an apparent paradox: while Brazil ranks 43rd in science and technology performance among the world's nations, it nevertheless ranks 27th among exporters of high-technology products. Examples will be presented on the current progress in science and technology development in fields such as nuclear, computers, information, agricultural and health sciences, as well as on the implementation of novel legal approaches to induce innovation. The latter is seen as a precondition to strengthen the competitiveness of key industries, especially their entry into the rapidly evolving international market. (author)

    2002-07-18

    The Humid Air Turbine (HAT) Cycle Technology Development Program focused on obtaining HAT cycle combustor technology that will be the foundation of future products. The work carried out under the auspices of the HAT Program built on the extensive low emissions stationary gas turbine work performed in the past by Pratt & Whitney (P&W). This Program is an integral part of technology base development within the Advanced Turbine Systems Program at the Department of Energy (DOE) and its experiments stretched over 5 years. The goal of the project was to fill in technological data gaps in the development of the HAT cycle and identify a combustor configuration that would efficiently burn high moisture, high-pressure gaseous fuels with low emissions. The major emphasis will be on the development of kinetic data, computer modeling, and evaluations of combustor configurations. The Program commenced during the 4th Quarter of 1996 and closed in the 4th Quarter of 2001. It teamed the National Energy Technology Laboratory (NETL) with P&W, the United Technologies Research Center (UTRC), and a subcontractor on-site at UTRC, kraftWork Systems Inc. The execution of the program started with bench-top experiments that were conducted at UTRC for extending kinetic mechanisms to HAT cycle temperature, pressure, and moisture conditions. The fundamental data generated in the bench-top experiments was incorporated into the analytical tools available at P&W to design the fuel injectors and combustors. The NETL then used the hardware to conduct combustion rig experiments to evaluate the performance of the combustion systems at elevated pressure and temperature conditions representative of the HAT cycle. The results were integrated into systems analysis done by kraftWork to verify that sufficient understanding of the technology had been achieved and that large-scale technological application and demonstration could be undertaken as follow-on activity. An optional program extended the experimental combustion evaluations to several specific technologies that can be used with HAT technology. After 5 years of extensive research and development, P&W is pleased to report that the HAT Technology Development Program goals have been achieved. With 0 to 10 percent steam addition, emissions achieved during this program featured less than 8 ppm NO{sub x}, less than 16 ppm CO, and unburned hydrocarbons corrected to 15 percent O{sub 2} for an FT8 engine operating between 0 and 120 F with 65 to 100 percent power at any day.

    1995-09-01

    In verifying the effectiveness of the deep geothermal resource exploration technology, development is being carried out on a fracture-type reservoir exploration method. The seismic exploration method investigates detailed structures of underground fracture systems by using seismic waves generated on the ground surface. Verification experiments for fiscal 1994 were carried out by selecting the Kakkonda area in which small fracture networks form reservoir beds. Geothermal resources in deep sections (deeper than 2000 m with temperatures higher than 350{degree}C) are promising in terms of amount of the resources, but anticipated with difficulty in exploration and impediments in drilling. To avoid these risks, studies are being progressed on the availability of resources in deep sections, their utilization possibility, and technologies of effective exploration and drilling. This paper summarizes the results of deep resource investigations during fiscal 1994. It also describes such technological development as hot water utilizing power generation. Development is performed on a binary cycle power generation plant which pumps and utilizes hot water of 150 to 200{degree}C by using a downhole pump. The paper also reports development on element technologies for hot rock power generation systems. It also dwells on development of safe and effective drilling and production technologies for deep geothermal resources.

  12. ISO: international standards development for nuclear technology

    International Nuclear Information System (INIS)

    The importance of internationally recognized standards for nuclear technology and safety is rapidly increasing for technical as well as economical and political reasons such as public acceptance and nuclear technology transfer to developing countries. The need for such standards is also evident because of the large number of nuclear installations sited close to international borders, and the export of nuclear installations from relatively few supplier countries to a large number of user countries. It is the purpose of this report to describe briefly the history, organizational structures and procedures, goals, accomplishments, problems, and future needs of the relevant activities of the International Organization for Standardization (ISO). ISO is composed of the partly governmental, partly non-governmental national standards bodies of 86 countries including China. The work of its Technical Committee (TC) 85 'Nuclear Energy' is mostly concerned with industrial applications, contractual aspects and international communication, for the benefit of both developed and developing countries. It works in close liaison with IAEA, which develops Codes and Guides addressed mainly to the regulatory aspects of nuclear power plants in developing countries. ISO/TC 85 has four sub-committees dealing with: (a) Terminology, Definitions, Units and Symbols (Secretariat USA, four working groups (WGs)); (b) Radiation Protection (Secretariat France, ten WGs); (c) Power Reactor Technology (Seten WGs); (c) Power Reactor Technology (Secretariat Sweden, nine WGs); (d) Nuclear Fuel Technology (Secretariat F.R.

  18. Technology certification and technology acceptance: Promoting interstate cooperation and market development for innovative technologies

    International Nuclear Information System (INIS)

    In the past two years, public and private efforts to promote development and deployment of innovative environmental technologies have shifted from the analysis of barriers to the implementation of a variety of initiatives aimed at surmounting those barriers. Particular attention has been directed at (1) streamlining fragmented technology acceptance processes within and among the states, and (2) alleviating disincentives, created by inadequate or unverified technology cost and performance data, for users and regulators to choose innovative technologies. Market fragmentation currently imposes significant cost burdens on technology developers and inhibits the investment of private capital in environmental technology companies. Among the responses to these problems are state and federal technology certification/validation programs, efforts to standardize cost/performance data reporting, and initiatives aimed at promoting interstate cooperation in technology testing and evaluation. This paper reviews the current status of these initiatives, identifies critical challenges to their success, and recommends strategies for addressing those challenges

  1. Development of industrial ion implantation technology

    International Nuclear Information System (INIS)

    On a cooperation between KAERI, Kurchatov Institute (Russia), and Mirae Co., development of a metal ion implanter and ion implantation technology is performed on a basic idea of popularization and refinement of ion implantation technology applied to the industrial components. The developed implanter is a two beam type: the mass separation line produces several mA of metal ion beams and the non-separation line produces several tens of mA gas ion beams, thus making the synergistic effect possible by the irradiation of beams from both lines. The target is made of a rotating plate of 60cm in radius and can treat various types of industrial components or parts. About 60 kinds of specimens were treated for the development of implantation technology. Two or five times lengthening of longevities were achieved on the PCB drills, razor blades, cutters, and precision dies. (Author)

  2. Development of national safeguards inspection technology

    International Nuclear Information System (INIS)

    It is considered that the safeguards trend in the IAEA and international nonproliferation regime is being accelerated toward strengthened safeguards system. In order to effectively respond to the stream as a whole, government has to have a firm policy-intention on nuclear non-proliferation, and supporting stance as to the stream should be taken consistently. Also, technological development satisfying the non-proliferation requirement would be pursued for the establishment of transparency and the enhancement of international confidence. At present, Korea stands at take-off stage in terms of safeguards. Therefore, necessary measures such as arrangement of legal framework, staffing and training of inspection man-power, and purchase of inspection equipment should be taken at the same time for earlier settlement of national safeguards system. In this connection, international cooperation with the share of the inspection results and equipment between the IAEA and TCNC is demanded. In the long term, the development of inspection technology as well as the research of sophisticated technology will have to be pursued. Emphasis should be placed on the regional safeguards system as well. In addition, it is necessary to ensure internationally that nuclear technological development to be planned is development of safeguards technology. (author). 20 tabs., 24 figs., 45 refs

    A laser ablation decontamination technology which is reportedly effective for a removal of fixed contaminants has been developed for three years as the first stage of the development. Lab scale experimental equipment was fabricated and the process variables have been assessed for determination of appropriate decontamination conditions at the laser wave lengths of 1,064 nm and 532 nm, respectively. The decontamination tests using radioactive specimens showed that the decontamination efficiency was about 100 which is quite a high value. An electrokinetic-flushing, an agglomeration leaching and a supercritical CO2 soil decontamination technology were development for a decontamination of radioactive soil wastes from the decommissioned sites of the TRIGA research reactor and the uranium conversion facilities. The remediation monitoring key technologies such as a representative sample taking and a measurement concept for the vertical distribution of radionuclides were developed for an assessment of the site remediation. Also an One-Dimensional Water Flow and Contaminant Transport in Unsaturated Zone (FTUNS) code was developed to interpretate the radionuclide migration in the unsaturated zone. The chemical gel decontamination process with more effective drying, rheological and decontaminating properties than the existing commercial gel decontamination technology has been developed for a decontamination of the fixed contamination of extremely high radiation facilities. Its performance were verified for the in-situ large scale application through the demonstration test using the radioactive facilities in KNFC contaminated with uranium.

    The U.S. is the largest producer of mining products in the world. In 2003, U.S. mining operations produced $57 billion worth of raw materials that contributed a total of $564 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation; (2) Solid-liquid separation; (3) Chemical/Biological Extraction; (4) Modeling and Control; and (5) Environmental Control.

    There is concern that the carbon prices generated through climate policies are too low to create the incentives necessary to stimulate technological development. This paper empirically analyzes how the Swedish carbon dioxide (CO2) tax and the European Union emission trading system (EU ETS) have affected productivity development in the Swedish pulp and paper industry 1998-2008. A Luenberger total factor productivity (TFP) indicator is computed using data envelopment analysis. The results show that climate policy had a modest impact on technological development in the pulp and paper industry, and if significant it was negative. The price of fossil fuels, on the contrary, seems to have created important incentives for technological development. Hence, the results suggest that the carbon prices faced by the industry through EU ETS and the CO2 tax have been too low. Even though the data for this study is specific for Sweden, the models and results are applicable internationally. When designing policy to mitigate CO2 emissions, it is vital that the policy creates a carbon price that is high enough - otherwise the pressure on technological development will not be sufficiently strong.

    The scope of this project is to establish the basic analysis technologies for the advanced designed with the passive and inherent safety concepts. The scope is extended to the application of these technologies to the performance and safety analysis of the passive reactor. Since the different design concepts are applied depending on the reactor power, the study is conducted for the small and medium sized integral reactor as well as the large scale passive reactors by focusing on the analysis technology development for the passive components. The design concepts which can be applied for the safety enhancement of the domestic advanced reactor are developed through evaluating the technical information of the overseas advanced reactor concepts.

  14. Developing innovative environmental technologies for DOE needs

    International Nuclear Information System (INIS)

    Environmental restoration and waste management activities at US Department of Energy (DOE) facilities are diverse and complex. Contamination at DOE sites and facilities includes radionuclides, chlorinated hydrocarbons, volatile organic compounds, non-aqueous phase liquids, and heavy metals, among others. Soil and groundwater contamination are major areas of concern and DOE has focused very significant efforts in these areas. Relevant technology development activities are being conducted at DOE's own national laboratories, as well as through collaborative efforts with other federal agencies and the private sector. These activities span research and development (R ampersand D) of new concepts and techniques to demonstration and commercialization of mature technologies. Since 1990, DOE has also supported R ampersand D of innovative technologies through interagency agreements with US Environmental Protection Agency (EPA), US Department of Defense, the National Science Foundation, and others

    The U.S. is the largest producer of mining products in the world. In 2003, U.S. mining operations produced $57 billion worth of raw materials that contributed a total of $564 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Originally set up by Virginia Tech and West Virginia University, this endeavor has been expanded into a seven-university consortium -- Virginia Tech, West Virginia University, University of Kentucky, University of Utah, Montana Tech, New Mexico Tech and University of Nevada, Reno - that is supported through U.S. DOE Cooperative Agreement No. DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation; (2) Solid-liquid separation; (3) Chemical/biological extraction; (4) Modeling and control; and (5) Environmental control. Distribution of funds is handled via competitive solicitation of research proposals through Site Coordinators at the seven member universities. These were first reviewed and ranked by a group of technical reviewers (selected primarily from industry). Based on these reviews, and an assessment of overall program requirements, the CAST Technical Committee made an initial selection/ranking of proposals and forwarded these to the DOE/NETL Project Officer for final review and approval. The successful projects are listed by category, along with brief abstracts of their aims and objectives.

  16. Strategic alliances in engineering, technology and development

    International Nuclear Information System (INIS)

    The role of strategic alliances in the development of heavy oil resources, both mineable and in-situ, is discussed. A strategic alliance is defined as a custom designed, long term collaborative working arrangement between two parties to pool, exchange, and integrate their resources to maximize mutual gain. A combination of one or more of the following success factors is seen as contributing to the unlocking of static heavy oil resources: sufficiently high and sustained crude oil prices; strategic intent to pursue heavy oil development regardless of short-term setbacks or economic downturns; technology breakthroughs that can reduce bitumen supply and upgrading costs; and strategic alliances. An idealized model for strategic alliances designed to help develop heavy oil resources is illustrated. The advantages and pitfalls involved in strategic alliances are listed along with the characteristics of viable contract agreements for such alliances. Some examples of strategic alliances in engineering and technology development are presented from Alberta experience. 2 figs., 1 tab

    Full Text Available The rapidly development and exceptional growing of Information and Communication Technology (ICT have continuously affected all aspects of life and activities in the world. ICT becomes a major factor that drives social, economic and human or individual development in one country. Individual who can't accept or use the technology innovation will suffer difficulties to go together with the world especially after a period of time when the innovation becomes an available commodity in the world. In spite of great development of ICT and high acceptance of the technology by organizations and individuals in developed nations, adoption and acceptance of ICT innovations, due to some determinants, are still low in developing countries including the Arab countries. Therefore a study, based on some relevant adoption model, needs to be conducted to understand and further discover about the adoption of ICT in developing countries especially in Arab world. The study includes comparing several adoption and innovation model in a way to identify a viable model for the adoption of technology in Jordan and other similar developing countries. The findings of the study will enhance our knowledge of the adoption and diffusion of ICT by concentration on an area hitherto neglected.

  18. The Asia Pacific LNG trade: Status and technology development

    International Nuclear Information System (INIS)

    The Asia Pacific Region is experiencing a period of sustained economic expansion. Economic growth has led to an increasing demand for energy that has spurred a rapid expansion of baseload liquefied natural gas (LNG) facilities in this region. This is illustrated by the fact that seven of the ten baseload facilities in existence provide LNG for markets in the Asia Pacific region. With the three exceptions having been initially commissioned in 1972 and earlier, it is fair to observed that most advances in LNG technology have been developed and applied for this market. The paper presents the current status and identified future trends for the Asia Pacific LNG trade. Technology development in terms of application to onstream production, processing and transportation facilities, including LNG tankers, is presented. The potential of future advances to applied technology and operational practices to improve the cost-effectiveness of new and existing facilities is discussed. Current design data and methods as actually used are examined in terms of identifying where fundamental research and basic physical data are insufficient for optimization purposes. These findings are then summarized and presented in terms of the likely evolution of future and existing LNG projects in the Asia Pacific region

  19. Development of hydrogen production technology using FBR

    International Nuclear Information System (INIS)

    This report describes the features of technology, the schedule and the organization for the research and development regarding the hydrogen production technology using FBR thermal energy. Now, the hydrogen production system is proposed as one of new business models for FBR deployment. This system is the production of hydrogen either thermal energy at approximately from 500degC to 550degC or electricity produced by a sodium cooled FBR. Hydrogen is expected to be one of the future clean secondary energies without carbon-dioxide emission. Meanwhile the global energy demand will increase, especially in Asian countries, and the energy supply by fossil fuels is not the best choice considering the green house effect and the stability of energy supply. The development of the hydrogen technology using FBR that satisfies 'sustainable energy development' and 'utilization of energies free from environmental pollution' will be one of the promising options. Based on the above mentioned recognition, we propose the direction of the development, the issues to be solved, the time schedule, the budget, and the organization for R and D of three hydrogen production technologies, the thermochemical hybrid process, the low temperature steam reforming process, and the high temperature steam electrolysis process in JNC.

  7. Development of key Technologies for Nuclear Hydrogen

    International Nuclear Information System (INIS)

    The researches performed in this project can be classified into five categories; high temperature materials for reactor and high temperature components, the nuclear graphite used for the core material of a VHTR, the essential technologies related to the structural integrity of high temperature components, ion-beam mixing technology as a part of the technologies to develop a process heat exchanger(PHE) and a small gas loop for the verification tests of a PHE. Researches on materials for reactor and high temperature components include creep properties of super alloy at an elevated temperature, phase stability of a modified 9Cr-1Mo alloy, and corrosion properties of the decomposer. Researches on thermal and physical properties such as oxidation, thermal conductivity, fracture toughness and strength were performed in an effort to establish technologies required for graphite selection of VHTR. Ion-beam coating and mixing technology has been developed for possible application to the process heat exchanger. Chamber for an ion beam deposition and mixing on a test PHE was fabricated and the process procedures were established. The design and construction of a small experimental gas loop is ongoing to perform verification tests on a 10kW PHE. This year, the primary system was designed in detail and completely constructed, and partly tested in a working condition

  8. Arm development review of existing technologies

    International Nuclear Information System (INIS)

    In the nuclear industry there is a requirement for remotely operated inspection devices with a horizontal reach of 5 m that fit inside access tubes with diameter of 0.2 m, that are able to support a tip mass of 2 kg plus a distributed mass of 0.5 kg/m. This report presents a review of deployable boom technologies which aims to identify technologies that --if suitably developed-- would have the potential to meet the above requirements. Fifteen different technologies are reviewed, of which six are found to be potentially of interest. After a further down selection, it is concluded that two technologies --push chains and thin-walled booms-- are the most promising. It is unclear if a single system can meet all of the requirements, but the selected technologies are seen to be complementary; the former being better suited to short-reach systems with heavier payloads and the latter to long-reach systems with lighter payloads. It is recommended that both technologies be further investigated. (author)

This process improves the transparency and relevance of technology investments, provides the community a voice in the process, and leverages the technology investments of external organizations by defining a need and a customer. Goals for the COR Program envisioned by the National Research Council’s (NRC) “New Worlds, New Horizons in Astronomy and Astrophysics” (NWNH) Decadal Survey report includes a 4m-class UV/optical telescope that would conduct imaging and spectroscopy as a post-Hubble observatory with significantly improved sensitivity and capability, a near-term investigation of NASA participation in the Japanese Aerospace Exploration Agency/Institute of Space and Astronautical Science (JAXA/ISAS) Space Infrared Telescope for Cosmology and Astrophysics (SPICA) mission, and future Explorers.

  10. Technologies in support of CANDU development

    International Nuclear Information System (INIS)

    Atomic Energy of Canada, Ltd. (AECL) has significant research and development (R and D) programs designed to meet the needs of both existing CANDU reactors and new and evolving CANDU plant designs. These R and D programs cover a wide range of technology, from chemistry and materials support through to inspection and life management tools. Emphasis is placed on effective technology development programs for fuel channels, feeders and steam generators to ensure their operation through design life, and beyond. This paper specifically addresses how the R and D has been applied in the production of longer-lived pressure tubes for the most recent CANDU 6 reactors, and how this technology forms the basis for the pressure tubes of the Advanced CANDU Reactor (ACR). Similarly, AECL has developed solutions for other critical components such as calandria tubes, feeder pipe and steam generators. The paper also discusses how the R and D knowledge has been integrated into aging management databases and health monitoring tools. Since 1997, AECL has been working with CANDU utilities on comprehensive and integrated CANDU Plant Life Management (PLiM) programs for successful and reliable plant operation through design life and beyond. AECL has developed and implemented an advanced chemistry monitoring and diagnostic system, called ChemAND which allows on-line access by the operators to current and past chemistry conditions enabling appropriate responses and facilitating planning of shutdoponses and facilitating planning of shutdown maintenance actions. An equivalent tool for monitoring, trending and diagnosing thermal and mechanical data has also been developed; this tool is called ThermAND. AECL is developing the Maintenance Information, Monitoring, and Control (MIMC) system, which provide information to the user for condition-based decision-making in maintenance. To enable more effective inspections, surveillance and data collection, AECL has developed unique one-off tooling to carry out unanticipated inspection and repair work. The X-probe transmit-receive array technology has been applied successfully for steam generator tube and feeder inspections. This technology reduces time and dose for those carrying out these inspections. Finally the paper discusses AECL's development of high quality specialty components that outperform industry standards Examples discussed here are nuclear pump seals, generic fluid sealing technology and Finned Strainers.

    International Nuclear Information System (INIS)

    In the present study, the KALIMER safety analysis has been made for the transients considered in the design concept, hypothetical core disruptive accident (HCDA), and containment performance with the establishment of the design basis. Such analyses have not been possible without the computer code improvement, and the experience attained during this research period must have greatly contributed to the achievement of the self reliance in the domestic technology establishment on the safety analysis areas of the conceptual design. The safety analysis codes have been improved to extend their applicable ranges for detailed conceptual design, and a basic computer code system has been established for HCDA analysis. A code-to-code comparison analysis has been performed as a part of code verification attempt, and the leading edge technology of JNC also has been brought for the technology upgrade. In addition, the research and development on the area of the database establishment has been made for the efficient and systematic project implementation of the conceptual design, through performances on the development of a project scheduling management, integration of the individually developed technology, establishment of the product database, and so on, taking into account coupling of the activities conducted in each specific area

  15. Decommissioning Technology Development for Nuclear Research Facilities

    International Nuclear Information System (INIS)

    It is predicted that the decommissioning of a nuclear power plant would happen in Korea since 2020 but the need of partial decommissioning and decontamination for periodic inspection and life extension still has been on an increasing trend and its domestic market has gradually been extended. Therefore, in this project we developed following several essential technologies as a decommissioning R and D. The measurement technology for in-pipe radioactive contamination was developed for measuring alpha/beta/gamma emitting nuclides simultaneously inside a in-pipe and it was tested into the liquid waste transfer pipe in KRR-2. And the digital mock-up system for KRR-1 and 2 was developed for choosing the best scenarios among several scenarios on the basis of various decommissioning information(schedule, waste volume, cost, etc.) that are from the DMU and the methodology of decommissioning cost estimation was also developed for estimating a research reactor's decommissioning cost and the DMU and the decommissioning cost estimation system were incorporated into the decommissioning information integrated management system. Finally the treatment and management technology of the irradiated graphites that happened after decommissioning KRR-2 was developed in order to treat and manage the irradiated graphites safely

    Rasmussen, Flemming; Madsen, Peter Hauge

    2011-01-01

    Text Over the past 25 years global wind energy capacity has doubled every three years, corresponding to a tenfold expansion every decade. By the end of 2010 global installed wind capacity was approximately 200 GW and in 2011 is expected to produce about 2% of global electricity consumption. The huge potential of wind, the rapid development of the technology and the impressive growth of the industry justify the perception that wind energy is changing its role to become the future backbone of a secure global energy supply. Between the mid-1980s, when the wind industry took off, and 2005 wind turbine technology has seen rapid development, leading to impressive increases in the size of turbines, with corresponding cost reductions. From 2005 to 2009 the industry’s focus seems to have been on increasing manufacturing capacity, meeting market demand and making wind turbines more reliable. The development of new and larger turbines to some extent stagnated, and costs even rose due to high demand and rising materials costs. We believe, however – and this is supported by recent trends – that the next decade will be a new period of technology development and further scale-up, leading to more cost-effective, reliable and controllable wind turbines and new applications. This is partly due to increased international competition, but also because the industry is increasingly dominated by high-technology international companies. The move to install more capacity offshore also favours larger wind turbines and encourages new ways of thinking. In this paper we discuss the current status of wind power and its prospects up to 2050, including both existing and emerging technologies.

    The goal of NASA s current EVA technology effort is to further develop technologies that will be used to demonstrate a robust EVA system that has application for a variety of future missions including microgravity and surface EVA. Overall the objectives will be to reduce system mass, reduce consumables and maintenance, increase EVA hardware robustness and life, increase crew member efficiency and autonomy, and enable rapid vehicle egress and ingress. Over the past several years, NASA realized a tremendous increase in EVA system development as part of the Exploration Technology Development Program and the Constellation Program. The evident demand for efficient and reliable EVA technologies, particularly regenerable technologies was apparent under these former programs and will continue to be needed as future mission opportunities arise. The technological need for EVA in space has been realized over the last several decades by the Gemini, Apollo, Skylab, Space Shuttle, and the International Space Station (ISS) programs. EVAs were critical to the success of these programs. Now with the ISS extension to 2028 in conjunction with a current forecasted need of at least eight EVAs per year, the EVA hardware life and limited availability of the Extravehicular Mobility Units (EMUs) will eventually become a critical issue. The current EMU has successfully served EVA demands by performing critical operations to assemble the ISS and provide repairs of satellites such as the Hubble Space Telescope. However, as the life of ISS and the vision for future mission opportunities are realized, a new EVA systems capability will be needed and the current architectures and technologies under development offer significant improvements over the current flight systems. In addition to ISS, potential mission applications include EVAs for missions to Near Earth Objects (NEO), Phobos, or future surface missions. Surface missions could include either exploration of the Moon or Mars. Providing an EVA capability for these types of missions enables in-space construction of complex vehicles or satellites, hands on exploration of new parts of our solar system, and engages the public through the inspiration of knowing that humans are exploring places that they have never been before. This paper offers insight into what is currently being developed and what the potential opportunities are in the forecast.

    1982-01-01

    The developmental history of photovoltaics is examined as a basis for predicting further advances to the year 2000. Transistor technology was the precursor of solar cell development. Terrestrial cells were modified for space through changes in geometry and size, as well as the use of Ag-Ti contacts and manufacture of a p-type base. The violet cell was produced for Comsat, and involved shallow junctions, new contacts, and an enhanced antireflection coating for better radiation tolerance. The driving force was the desire by private companies to reduce cost and weight for commercial satellite power supplies. Liquid phase epitaxial (LPE) GaAs cells are the latest advancement, having a 4 sq cm area and increased efficiency. GaAs cells are expected to be flight ready in the 1980s. Testing is still necessary to verify production techniques and the resistance to electron and photon damage. Research will continue in CVD cell technology, new panel technology, and ultrathin Si cells.

    Legislation will soon require significant carbon capture and sequestration (CCS) capabilities. The purpose of this paper is to show how advances in technology can further improve the high efficiencies of Integrated Gasification Combined Cycle (IGCC) power plants and to determine whether the efficiency penalty for pre-combustion removal of CO{sub 2} can be minimized. An in-house study was carried out and the methodology is explained. Technological developments are explained for IGCC in general, e.g., improved gas turbines, and for IGCC with CCS, e.g., in the field of more efficient water gas shift and CO{sub 2} removal processes. The results show that the 48 % coal-to-power efficiency can be surpassed and the efficiency penalty for CCS minimized to 7 %. This is possible using near-commercial technologies.

    International Nuclear Information System (INIS)

    The MATRA-LMR-FB has been developed internally for the damage prevention as well as the safety assessment during a channel blockage accident and, as a the result, the quality of the code becomes comparable to that developed in the leading countries. For a code-to-code comparison, KAERI could have access to the SASSYS-1 through a bilateral collaboration between KAERI and ANL. The study could bring into the reliability improvements both on the reactivity models in the SSC-K and on the SSC-K prediction capability. It finally leads to the completion of the SSC-K version 1.3 resulting from the qualitative and quantitative code-to-code comparison. The preliminary analysis for a metal fueled LMR could also become possible with the MELT-III and the VENUS-II, which had originally been developed for the HCDA analysis with an oxidized fuel, by developing the relevant models For the development of the safety evaluation technology, the safety limits have been set up, and the analyses of the internal and external channel blockages in an assembly have also been performed. Besides, the more reliable analysis results on the key design concepts could be obtained by way of the methodology improvement resulting from the qualitative and quantitative comparison study. For an efficient and systematic control of the main project, the integration of the developed technologies and the establishment of their data base have been pursued.

    International Nuclear Information System (INIS)

    The basis of the national liquid metal design technology development has been prepared by developing the KALIMER-600 core design concept with elimination of blanket elements and with single enrichment fuel in order to improve proliferation resistance. The safety of this core was enhanced by several design techniques to reduce the sodium coolant void reactivity. It led to be selected as a GEN-IV reference core with Japanese JSFR. Additionally, the direction refabrication core concept where the spent fuel is simply treated without change of its composition was developed to achieve economy and proliferation resistance by keeping high power density. Development of a combined method based on subchannel analysis and porous media approach will be the more detailed analysis code for the thermo-mechanical integrity of the duct wall and the combined code will be join the rank of advanced technology of LMR core thermal hydraulics. The design requirements of the metallic fuel including MA were analyzed. The constituent migration model was developed for the ternary metallic fuel slug, and the constituent migration which is one of the issues of the metallic fuel development was analyzed by the developed model. The performance of the fuel rod and the thermo-mechanical behavior of the assemblies were analyzed. The design specifications of the fuel rod/assembly for KALIMER-600 were derived by the analyzed results

  8. Fast breeder reactor technology development in China

    International Nuclear Information System (INIS)

    Based on envisaged long term needs and development of energy resources and electricity generation in China, it was proved that fast breeder reactor should be developed and commercially deployed when the thermal reactor could not be continuously built due to lack of nuclear fuels. In my estimation the time left to us for the FBR technology development is only 20-25 years from now. The general description of the role played by FBRs in Chinese energy resources and its urgency are analysed in the paper. According to the strategy study the Chinese FBR technology would be divided into three steps. The first step is an experimental fast reactor (CEFR) with a thermal power of 65 MWt matched with 25 MWe turbine generator followed by modulized fast breeder reactor and large fast breeder reactor. The paper briefs main characteristics of the CEFR based on its conceptual design. In the paper, the emphasis are put on the safety aspects: safety demands, design results and accidents envisaged to be analysed. The status of the research and development for FBR technology in China is summarized. Finally the engineering preparation status of the CEFR is presented in the paper. (author)

  10. Development of Advanced Ceramic Manufacturing Technology; FINAL

    International Nuclear Information System (INIS)

    Advanced structural ceramics are enabling materials for new transportation engine systems that have the potential for significantly reducing energy consumption and pollution in automobiles and heavy vehicles. Ceramic component reliability and performance have been demonstrated in previous U.S. DOE initiatives, but high manufacturing cost was recognized as a major barrier to commercialization. Norton Advanced Ceramics (NAC), a division of Saint-Gobain Industrial Ceramics, Inc. (SGIC), was selected to perform a major Advanced Ceramics Manufacturing Technology (ACMT) Program. The overall objectives of NAC's program were to design, develop, and demonstrate advanced manufacturing technology for the production of ceramic exhaust valves for diesel engines. The specific objectives were (1) to reduce the manufacturing cost by an order of magnitude, (2) to develop and demonstrate process capability and reproducibility, and (3) to validate ceramic valve performance, durability, and reliability. I n order to achieve these objectives, NAC, a leading U.S. advanced ceramics component manufacturer, assembled a multidisciplinary, vertically integrated team. This team included: a major diesel engine builder, Detroit Diesel Corporation (DDC); a corporate ceramics research division, SGIC's Northboro R and D Center; intelligent processing system developers, BDM Federal/MATSYS; a furnace equipment company, Centorr/Vacuum Industries; a sintering expert, Wittmer Consultants; a production OEMert, Wittmer Consultants; a production OEM, Deco-Grand; a wheel manufacturer and grinding operation developer, Norton Company's Higgins Grinding Technology Center (HGTC); a ceramic machine shop, Chand Kare Technical Ceramics; and a manufacturing cost consultant, IBIS Associates. The program was divided into four major tasks: Component Design and Specification, Component Manufacturing Technology Development, Inspection and Testing, and Process Demonstration

  11. Prospects and development of radiation technologies in developing countries

    International Nuclear Information System (INIS)

    Radiation processing has established itself as a commercially viable technology that can be beneficially used to enhance the characteristics of many materials. More than 200 gamma irradiators and over 1000 industrial electron beam accelerators are operating world wide in the established applications like medical product sterilization, polymer modifications and a few in number for food irradiation applications. Studies on economic feasibility have been carried out on industrial and semi-industrial scale, for emerging applications like flue gas treatment, industrial, domestic water and sewage sludge treatment. Many developing countries have realized the immense potential and benefits, with some of them installing gamma irradiators/ electron accelerators mainly for medical products sterilization and polymer modifications meeting specific needs. Efforts are also being continued by governmental / national bodies through setting up technological/pilot scale demonstration plants to encourage the private entrepreneurs to use /set up such facilities. However, two factors - the cost and non-availability of the associated equipment are hindering the effective utilization of the technology to make a big way in developing countries. This paper presents the details on the developments, prospects and the ongoing efforts to enhance the utilization of radiation technology for various applications in developing countries, with a specific mention about India.

  12. Aerocapture Technology Development for Planetary Science - Update

    Science.gov (United States)

    Munk, Michelle M.

    2006-01-01

    Within NASA's Science Mission Directorate is a technological program dedicated to improving the cost, mass, and trip time of future scientific missions throughout the Solar System. The In-Space Propulsion Technology (ISPT) Program, established in 2001, is charged with advancing propulsion systems used in space from Technology Readiness Level (TRL) 3 to TRL6, and with planning activities leading to flight readiness. The program's content has changed considerably since inception, as the program has refocused its priorities. One of the technologies that has remained in the ISPT portfolio through these changes is Aerocapture. Aerocapture is the use of a planetary body's atmosphere to slow a vehicle from hyperbolic velocity to a low-energy orbit suitable for science. Prospective use of this technology has repeatedly shown huge mass savings for missions of interest in planetary exploration, at Titan, Neptune, Venus, and Mars. With launch vehicle costs rising, these savings could be the key to mission viability. This paper provides an update on the current state of the Aerocapture technology development effort, summarizes some recent key findings, and highlights hardware developments that are ready for application to Aerocapture vehicles and entry probes alike. Description of Investments: The Aerocapture technology area within the ISPT program has utilized the expertise around NASA to perform Phase A-level studies of future missions, to identify technology gaps that need to be filled to achieve flight readiness. A 2002 study of the Titan Explorer mission concept showed that the combination of Aerocapture and a Solar Electric Propulsion system could deliver a lander and orbiter to Titan in half the time and on a smaller, less expensive launch vehicle, compared to a mission using chemical propulsion for the interplanetary injection and orbit insertion. The study also identified no component technology breakthroughs necessary to implement Aerocapture on such a mission. Similar studies of Aerocapture applications at Neptune, Venus, and Mars were studied in 2003 through 2005. All showed significant performance improvements for the missions studied. Findings from these studies were used to guide the technology development tasks originally solicited in a 2002 NASA ROSS Research Announcement. The tasks are now in their final year and have provided numerous improvements in modeling and hardware, for use in proposals or new mission starts. Major Accomplishments: Since validation of the Aerocapture maneuver requires a space flight, ground developments have focused on modeling and environment prediction, materials, and sensors. Lockheed Martin has designed and built a 2-meter Carbon-Carbon aeroshell "hot structure." The article utilizes co-cured stiffening ribs and advanced insulation to achieve large scale, and up to a 40% reduction in areal density over the Genesis probe construction. This concept would be an efficient solution for probes that experience heat rates near 800-1000 W/cm(exp 2), such as at Venus and Earth. Applied Research Associates has extensively tested a family of efficient ablative TPS materials that provide solutions for a range of heating conditions. These materials are being applied to high-temperature structures built by ATK Space Systems, led by Langley Research Center. One-meter aeroshells will be thermally tested to validate construction and demonstrate higher bondline temperatures, which can lead to mass savings of up to 30% over traditional heatshields. Ames Research Center has developed aeroshell instrumentation that could measure environmental conditions and material performance during atmospheric entry. Instruments to measure TPS recession, heat flux, and catalycity could be combined with traditional sensors to provide a "plug-and-play" system for minimal mass and power, that would acquire flight data for model improvement and risk reduction on future missions. Improved atmospheric and aerothermodynamic models ha also been a major focus of the program. Next Steps: Aerocapture is one of fi

  13. Development of risk-informed application technology

    International Nuclear Information System (INIS)

    This project aims at developing a risk-informed application technology to enhance the safety and economy of nuclear power plant altogether. For this, the PSA standard model is developed which meets the ASME PSA Standard Capability Category I +. In addition, to reduce the uncertainty of PSA, several new PSA technologies are developed. A methodology is developed to quantify the fault trees of initiating events and mitigation systems simultaneously, and a new measure is developed to judge the convergency of PSA results. A new frame is proposed to combine the Level 1 and 2 PSA models into a unified PSA model. The fire risk is re-assessed using a fire analysis computer code. To develop a risk-informed decision making framework, a new method to derive the importance of systems with common cause events is proposed. And it is proposed that a framework for eliciting and combining the experts' opinions consistently. The research results can be used in the regulatory body and the industry projects for risk-informed applications

    Lewellen, Tom K

    2008-09-01

    Positron emission tomography (PET) is a tool for metabolic imaging that has been utilized since the earliest days of nuclear medicine. A key component of such imaging systems is the detector modules--an area of research and development with a long, rich history. Development of detectors for PET has often seen the migration of technologies, originally developed for high energy physics experiments, into prototype PET detectors. Of the many areas explored, some detector designs go on to be incorporated into prototype scanner systems and a few of these may go on to be seen in commercial scanners. There has been a steady, often very diverse development of prototype detectors, and the pace has accelerated with the increased use of PET in clinical studies (currently driven by PET/CT scanners) and the rapid proliferation of pre-clinical PET scanners for academic and commercial research applications. Most of these efforts are focused on scintillator-based detectors, although various alternatives continue to be considered. For example, wire chambers have been investigated many times over the years and more recently various solid-state devices have appeared in PET detector designs for very high spatial resolution applications. But even with scintillators, there have been a wide variety of designs and solutions investigated as developers search for solutions that offer very high spatial resolution, fast timing, high sensitivity and are yet cost effective. In this review, we will explore some of the recent developments in the quest for better PET detector technology. PMID:18695301

    International Nuclear Information System (INIS)

    The US DOE Office of Technology Development (OTD) is currently evaluating the Plasma Hearth Process (PHP) for potential treatment of several DOE waste types. The PHP is a high-temperature vitrification process that has potential application for a wide range of mixed waste types in both the low-level and transuranic mixed waste categories. The PHP is being tested under both the OTD Mixed Waste Integrated Program and the Buried Waste Integrated Demonstration. Initial testing has been completed on several different surrogate waste forms that are representative of some of the DOE mixed waste streams. Destruction of organic material exceeds that of conventional incineration technologies. The vitrified residual has leaching characteristics comparable to glass formulations produced in the high-level waste program. The first phase of the PHP demonstration project has been successfully completed, and the project is currently beginning a comprehensive second phase of development and testing

  16. Health and research organization to meet complex needs of developing energy technologies

    International Nuclear Information System (INIS)

    At the Lawrence Livermore Laboratory, a unique safety technology organization has been established that is especially geared to respond to interdisciplinary health and safety questions in response to rapidly growing energy technology problems. This concept can be adopted by smaller organizations at a more modest cost, and still maintains the efficiency, flexibility, and technical rigor that are needed more and more in support of any industry health and safety problem. The separation of the technology development role from the operation safety organization allows the operational safety specialists to spend more time upgrading the occupational health and safety program but yet provides the opportunity for interchange with health and safety technology development specialists. In fact, a personnel assignment flow between an operational health and safety organization and a special technology development organization provides a mechanism for upgrading the overall safety capability and program provided by a given industrial or major laboratory

  4. Development of FBR Fuel Cycle Technology in Japan

    International Nuclear Information System (INIS)

    In the FaCT project, the integration of the sodium-cooled fast reactor with oxide fuel, the advanced aqueous reprocessing and the simplified pelletizing fuel fabrication were selected as the main concept for commercialization. The reprocessing concept is constructed based on the well established aqueous reprocessing. Some innovative technologies are adopted for the aqueous reprocessing in order to realize MA recycle as well as economical competitiveness. U/Pu separation technology of the NEXT system has some options according to the specification of reprocessing fuels and products. The fuel fabrication concept is constructed based on the simplified palletizing method process in which innovative technologies are adopted to rationalize pellet fabrication process such as the plutonium content adjusting performed by solution mixing, binder-less granulation process and die wall lubrication pressing. Additional innovative technologies are settled because of high heat generation caused by decay heat of MA and high radio-activity of the fuel. Various investigation, laboratory scale hot tests, semi-engineering scale tests (cold and/or uranium), conceptual design study etc. are still going on. In 2008, JAEA has summarized current status of these development and rechecked the R and D deployment achieving goal targets at a check and review in 2010. These innovative technologies are decided to be adopted or not in 2010, on schedule. Furthermore, middle to long term R and D deploymrmore, middle to long term R and D deployment has been under discussion considering urgent matters such as how to cope with the transition from LWR cycle to FBR cycle, fuel supply for the demonstration reactor etc. (author)

  5. The technological development of neutron radiography

    International Nuclear Information System (INIS)

    Neutron radiography is a relatively recent technological development in the annals of non-destructive evaluation. It promises to play a role of increasing importance as the technology is further developed. The technique is placed in prospective with regard to other non-destructive evaluation methods in this paper. The history of the development of neutron radiography is traced to the early work of Becker, Bothe and the Joliot-Curies in Europe, and to the work of Chadwick in Great Britain. Details of the experiments which led to the discovery of the neutron by Chadwick in 1932, nuclear properties and energy classifications of neutrons, and the various interactions of neutrons with matter are discussed in detail. A history of neutron radiography is presented which outlines the early experiments by Kallmann and Kuhn; these experiments led to the production of the first neutron radiograph in Germany in 1938. The paper continues with a description of the general techniques that are characteristic of the neutron radiographic process. The breadth and extent of present neutron radiographic technology is discussed as a conclusion of the paper. (author)

    It is believed that it is easier for Korea to become self-reliant in PHWR technology than in PWR technology, mainly because of the lower design pressure and temperature and because of the simplicity, economy, flexibility of the fuel cycle in comparison with PWR systems. Even though one has no doubt about the safety and the economics of the PHWR`s that are now being operated or constructed in Korea, it is necessary to develop the advanced design technology for even safer and more economical PHWR systems to overcome the ever growing international resistance to sharing of nuclear technology and to meet the even more stringent requirements for the future public acceptance of nuclear power. This study is to develop the more advance design technology compared to the existing one, by performing in-depth studies especially in the field of reactor physics, safety systems and safety evaluation to realize the above requirements. 90 figs, 50 tabs, 38 refs.

    International Nuclear Information System (INIS)

    Since the amount of the spent fuel rapidly increases, the current R and D activities are focused on the technology development related with the storage and utilization of the spent fuel. In this research, to provide such a technology, the mechanical head-end process has been developed. In detail, the swing and shock-free crane and the RCGLUD(Remote Cask Grappling and Lid Unbolting Device) were developed for the safe transportation of the spent fuel assembly, the LLW drum and the transportation cask. Also, the disassembly devices required for the head-end process were developed. This process consists of an assembly downender, a rod extractor, a rod cutter, a fuel decladding device, a skeleton compactor, a force-rectifiable manipulator for the abnormal spent fuel disassembly, and the gantry type telescopic transporter, etc. To provide reliability and safety of these devices, the 3 dimensional graphic design system is developed. In this system, the mechanical devices are modelled and their operation is simulated in the virtual environment using the graphic simulation tools. So that the performance and the operational mal-function can be investigated prior to the fabrication of the devices. All the devices are tested and verified by using the fuel prototype at the mockup facility

    2007-01-01

    NASA's In-Space Propulsion Technology Program has developed the first generation of solar sail propulsion systems sufficient to accomplish inner solar system science and exploration missions. These first generation solar sails, when operational, will range in size from 40 meters to well over 100 meters in diameter and have an areal density of less than 13 grams per square meter. A rigorous, multi-year technology development effort culminated in 2005 with the testing of two different 20-m solar sail systems under thermal vacuum conditions. The first system, developed by ATK Space Systems of Goleta, California, uses rigid booms to deploy and stabilize the sail. In the second approach, L'Garde, Inc. of Tustin, California uses inflatable booms that rigidize in the coldness of space to accomplish sail deployment. This effort provided a number of significant insights into the optimal design and expected performance of solar sails as well as an understanding of the methods and costs of building and using them. In a separate effort, solar sail orbital analysis tools for mission design were developed and tested. Laboratory simulations of the effects of long-term space radiation exposure were also conducted on two candidate solar sail materials. Detailed radiation and charging environments were defined for mission trajectories outside the protection of the earth's magnetosphere, in the solar wind environment. These were used in other analytical tools to prove the adequacy of sail design features for accommodating the harsh space environment. Preceding and in conjunction with these technology efforts, NASA sponsored several mission application studies for solar sails. Potential missions include those that would be flown in the near term to study the sun and be used in space weather prediction to one that would use an evolved sail capability to support humanity's first mission into nearby interstellar space. This paper will describe the status of solar sail propulsion within NASA, nearterm solar sail mission applications, and near-term plans for further development.

  17. Development of Reconstitution Technology for Surveillance Specimens

    International Nuclear Information System (INIS)

    The Japan Power Engineering and Inspection Corporation (JAPEIC) has been carrying out the project titled 'Nuclear Power Plant Integrated Management Technology (PLIM)' consigned by Japanese Ministry of Economy, Trade and Industry (METI) since 1996FY as a 10-years project. As one of the project themes, development of reconstitution technology for reactor pressure vessel (RPV/RV) surveillance specimens, which are installed in RPVs to monitor the neutron irradiation embrittlement on RPV/RV materials, is now on being carried out to deal with the long-term operation of nuclear power plants. The target of this theme is to establish the technical standard for applicability of reconstituted surveillance specimens including the reconstitution of the Charpy specimens and Compact Tension (CT) specimens. With the Charpy specimen reconstitution, application of 10 mm length inserts is used, which enables the conversion of tests from the LT-direction to the TL-direction. This paper presents the basic data from Charpy and CT specimens of RPV materials using the surveillance specimens obtained for un-irradiated materials including the following. 1) Reconstitution Technology of Charpy Specimens. a) The interaction between plastic zone and Heat Affected Zone (HAZ). b) The effects of the possible deviations from the standard specimens for the reconstituted specimens. 2) Reconstitution Technology of CT specimens. a) The correlation between fracture toughness and plastic zone width. Because toughness and plastic zone width. Because the project is now in progress, this paper describes the outline of the results obtained as of the end of 2000 FY. (authors)

    ElectroNeedles technology was developed as part of an earlier Grand Challenge effort on Bio-Micro Fuel Cell project. During this earlier work, the fabrication of the ElectroNeedles was accomplished along with proof-of-concept work on several electrochemically active analytes such as glucose, quinone and ferricyanide. Additionally, earlier work demonstrated technology potential in the field of immunosensors by specifically detecting Troponin, a cardiac biomarker. The current work focused upon fabrication process reproducibility of the ElectroNeedles and then using the devices to sensitively detect p-cresol, a biomarker for kidney failure or nephrotoxicity. Valuable lessons were learned regarding fabrication assurance and quality. The detection of p-cresol was accomplished by electrochemistry as well as using fluorescence to benchmark ElectroNeedles performance. Results from these studies will serve as a guide for the future fabrication processes involving ElectroNeedles as well as provide the groundwork necessary to expand technology applications. One paper has been accepted for publication acknowledging LDRD funding (K. E. Achyuthan et al, Comb. Chem. & HTS, 2008). We are exploring the scope for a second paper describing the applications potential of this technology.

    ATP's Mission and Operations. The ATP partners with industry to accelerate the development of innovative technologies for broad national economic benefit. The program's focus is on co-funding collaborative, multi-disciplinary technologies and enabling technology platforms that appear likely to be commercialized, with private sector funding, once the high technical risks are reduced. Industry-led projects are selected for funding in rigorous competitions on the basis of technical and economic merit. Since 1990, ATP has co-funded 642 projects, with 1,329 participants and another 1,300 subcontractors. Measuring to Mission: Overview of ATP's Evaluation Program. ATP's multi-component evaluation strategy provides measures of progress and performance matched to the stage of project evolution; i.e., for the short-term, from the time of project selection and over the course of the R for the mid-term, as commercial applications are pursued, early products reach the market, and dissemination of knowledge created in the R projects occurs; and for the longer-term, as more fully-developed technologies diffuse across multiple products and industries. The approach is applicable to all public S programs and adaptable to private or university projects ranging from basic research to applied industrial R. Examples of Results. ATP's composite performance rating system assesses ATP's completed projects against multi-faceted performance criteria of Knowledge Creation and Dissemination and Commercialization Progress 2-3 years after the end of ATP-funded R. It generates scores ranging from zero to four stars. Results for ATP's first 50 completed projects show that 16are in the bottom group of zero or one stars. 60the middle group. It is understood that not all ATP projects will be successful given the program's emphasis on funding high-risk technology development that the private sector is unwilling and unable to fund alone. Different technologies have different timelines for commercialization and diffusion. ATP has contracted a number of in-depth case studies of individual projects and groups of related projects. Given that the full timeline for economic impact extends many years after ATP funding ends, some studies are prospective, and others are retrospective. Some are a mix of the two. Quantitative economic impacts from just a few or the projects funded to date provide strong evidence that the ATP is addressing its ultimate goal of broad economic benefits to the nation and generating value that vastly exceeds the cost of the program to date.

    Full Text Available Information and Communication Technology (ICT, is fast becoming the principal agent and infrastructure for globalization and thus, has become a veritable tool for national development in many of the advanced nations. In these nations, human knowledge and skill have witnessed tremendous growth through the use of ICT. Unlike the Developing Countries (DCs where literacy, poverty, diseases and in fact low quality of life are the order of the day, the advanced nations have been able to overcome these problems through the adoption and deployment of technologies. The great difference between the DCs and advanced nations lies in manpower development. Knowledge has always been prime mover of prosperity. A knowledge society is the one with sure foundation for development, thus, we propose this framework as a simple way through which the DCs can quickly adopt and deploy ICT as instrument of manpower development and also as an infrastructure for national development. Our proposal includes government contributions and the benefits for both government and the citizens.

    The growth of computer power and connectivity, together with advances in wireless sensing and communication technologies, is transforming the field of complex distributed systems. The ability to deploy large numbers of sensors with a rapid, broadband communication system will enable high-fidelity, near real-time monitoring of complex systems. These technological developments will provide unprecedented insight into the actual performance of engineered and natural environment systems, enable the evolution of many new types of engineered systems for monitoring and detection, and enhance our ability to perform improved and validated large-scale simulations of complex systems. One of the challenges facing engineering is to develop methodologies to exploit the emerging information technologies. Particularly important will be the ability to assimilate measured data into the simulation process in a way which is much more sophisticated than current, primarily ad hoc procedures. The reports contained in this section on the Center for Complex Distributed Systems describe activities related to the integrated engineering of large complex systems. The first three papers describe recent developments for each link of the integrated engineering process for large structural systems. These include (1) the development of model-based signal processing algorithms which will formalize the process of coupling measurements and simulation and provide a rigorous methodology for validation and update of computational models; (2) collaborative efforts with faculty at the University of California at Berkeley on the development of massive simulation models for the earth and large bridge structures; and (3) the development of wireless data acquisition systems which provide a practical means of monitoring large systems like the National Ignition Facility (NIF) optical support structures. These successful developments are coming to a confluence in the next year with applications to NIF structural characterizations and analysis of large bridge structures for the State of California. Initial feasibility investigations into the development of monitoring and detection systems are described in the papers on imaging of underground structures with ground-penetrating radar, and the use of live insects as sensor platforms. These efforts are establishing the basic performance characteristics essential to the decision process for future development of sensor arrays for information gathering related to national security.

  2. Prices, technology development and the rebound effect

    International Nuclear Information System (INIS)

    Energy efficiency is the critical parameter for policies that aim at reducing energy consumption while maintaining or even boosting economic growth. The two main options to influence energy efficiency are changes in relative prices, i.e., raising the price of energy through economic instruments, or to introduce new technologies which increase the productivity of each unit of energy. This paper is based on the notion that in an equilibrium economy the marginal economic productivity is identical for all factors, i.e., energy, labour, knowledge and capital. From this premise two main conclusions can be drawn. First, any change in price or technology will have an impact on the whole economy by creating feedbacks through the substitution of factors of production and goods, as well as increased wealth. Second, the two policy approaches, changing relative prices and technology development, are not opposite to each other. They are the two faces of the same reality and should be developed and promoted simultaneous and consistently. (Author)

    The distributed optical fiber detection technology plays an important role in many fields, such as key regional security monitoring, pipeline maintenance and communication cable protection. It is superior to the traditional detector, and has a good prospect. This paper presents an overview of various distributed optical fiber sensors. At first, some related technologies of the optical fiber detection schemes are introduced in respect of sensing distance, real-time ability, signal strength, and system complexity; and the advantages and limitations of fiber gratings sensors, reflection-based optical fiber sensors, and interference- based optical fiber sensors are discussed. Then some advanced distributed optical fiber detection systems are mentioned. And the double-loop Sagnac distributed system is improved by adding photoelectric modulators and depolarizers. In order to denoise and enhance the original signal, a spectral subtraction-likelihood ratio method is improved. The experiment results show the spatial resolution is +/-15m per kilometer. Finally, based on the development trends of optical fiber detection technology at home and abroad, development tendency and application fields are predicted.

    2013-12-06

    The objective of this work was to investigate, develop, and validate the next generation of small hydroturbine generator designs that maximize the energy transfer from flowing water to electrical power generation. What resulted from this effort was the design of a new technology hydroturbine that Near Space Systems (NSS) has named the Star*Stream© Hydroturbine. Using a design that eliminates nearly all of the shortfalls of conventional hydroturbines, the Star*Stream© Hydroturbine employs a new mechanical-to-electrical energy transfer hydro design that operates without lubrication of any kind, and does not introduce foreign chemicals or particulate matter from oil or drive shaft seal degradation into the hydro ecology. In its unique configuration, the Star*Stream© Hydroturbine is nearly environmentally inert, without the negative aspects caused by interrupting the ecological continuity, i.e., disruptions to sedimentation, water quality, habitat changes, human displacement, fish migration, etc., - while it ensures dramatically reduced timeframes to project completion. While a remarkable reduction in LCOE resulting from application of the Star*Stream© Hydroturbine technology has been the core achievement of the this effort, there have been numerous technological breakthroughs from the development effort.

    Thieme, Lanny G.; Schreiber, Jeffrey G.; Mason, Lee S.

    2002-01-01

    The Department of Energy, Stirling Technology Company (STC), and NASA Glenn Research Center (GRC) are developing a free-piston Stirling convertor for a high-efficiency Stirling Radioisotope Generator (SRG) for NASA Space Science missions. The SRG is being developed for multimission use, including providing electric power for unmanned Mars rovers and deep space missions. NASA GRC is conducting an in-house technology project to assist in developing the convertor for space qualification and mission implementation. Recent testing of 55-We Technology Demonstration Convertors (TDC's) built by STC includes mapping of a second pair of TDC's, single TDC testing, and TDC electromagnetic interference and electromagnetic compatibility characterization on a non-magnetic test stand. Launch environment tests of a single TDC without its pressure vessel to better understand the convertor internal structural dynamics and of dual-opposed TDC's with several engineering mounting structures with different natural frequencies have recently been completed. A preliminary life assessment has been completed for the TDC heater head, and creep testing of the IN718 material to be used for the flight convertors is underway. Long-term magnet aging tests are continuing to characterize any potential aging in the strength or demagnetization resistance of the magnets used in the linear alternator (LA). Evaluations are now beginning on key organic materials used in the LA and piston/rod surface coatings. GRC is also conducting finite element analyses for the LA, in part to look at the demagnetization margin on the permanent magnets. The world's first known integrated test of a dynamic power system with electric propulsion was achieved at GRC when a Hall-effect thruster was successfully operated with a free-piston Stirling power source. Cleveland State University is developing a multi-dimensional Stirling computational fluid dynamics code to significantly improve Stirling loss predictions and assist in identifying convertor areas for further improvements. This paper will update the status and results for these efforts. .

    International Nuclear Information System (INIS)

    This document summarizes work being conducted under the U.S. Department of Energy's Office of Technology Development (EM-50) in support of the Tank Waste Remediation System (TWRS) Program. The specific work activities are organized by the following categories: safety, characterization, retrieval, barriers, pretreatment, low-level waste, and high-level waste. In most cases, the activities presented here were identified as supporting tank remediation by EM-50 integrated program or integrated demonstration lead staff and the selections were further refined by contractor staff. Data sheets were prepared from DOE-HQ guidance to the field issued in September 1993. Activities were included if a significant portion of the work described provides technology potentially needed by TWRS; consequently, not all parts of each description necessarily support tank remediation

  15. Solar Home System (SHS) in rural Bangladesh: Ornamentation or fact of development?

    International Nuclear Information System (INIS)

    Energy requirement has been growing every day due to higher population growth, and consequently higher consumption. About one third of rural households of Bangladesh are connected to the grid. To meet the gap, solar energy has been treated as a feasible option for people in rural areas where grid connections are not available. A good number of organizations have been working together to provide Solar Home System (SHS) in rural Bangladesh. There is little evidence that supply of small scale energy supports significant rural development. This paper aims at understanding how increased energy access through SHS in rural Bangladesh contributes towards rural development. Recent published literatures on SHS in Bangladesh have been studied to get insight into the technical, financial, and operational as well as economic and social issues. Later the findings have been critically analyzed with respect to selected indicators of rural development. The study identified that increased access to energy through SHS in rural Bangladesh provides mostly recreational and leisure benefits with the so called ‘social status’; income generation is negligible while support for education is average. - Highlights: • No specific proof is there to conclude that SHS has contributed to development. • SHS's contribution to income generation and employment is not significant. • SHS is mostly used for entertainment and to uplift the so called ‘social status’

  18. Technology development for future thorp reprocessing

    International Nuclear Information System (INIS)

    The Thorp reprocessing plant in the United Kingdom received its full Operating Licence in 1997. As commissioning demands diminished the opportunity was taken to consolidate reprocessing and related programmes of work in order ensure they remain focused on business priorities which will improve plant performance and meet customers current and future needs. The scope of work, technical objectives and organisational effectiveness have been systematically reviewed. Necessary changes have been implemented to improve the effectiveness of resource management and maintain clarity of business focus of the Technology Development Portfolio. Improvements to development techniques resulting from the years of process development and project commissioning support at Sellafield, culminating in Thorp's operation, are now being applied to the enhancement of Thorp's capabilities and performance and to other projects. These techniques have demonstrated significant reduction in research project capital investment and increased flexibility to meet operational demands. (author)

    International Nuclear Information System (INIS)

    Ammonia contacting method for prehardenning the surfaces of ADU liquid droplets and the ageing/washing/drying method and equipment for spherical dried-ADU particles were improved and tested with laboratory sacle. After the improvement of fabrication process, the sphericity of UO2 kernel obtained to 1.1, and the sintered density and O/U ratio of final UO2 kernel were above 10.60g/cm3. 2.01 respectively. Defects of SiC coating layer could be minimized by optimization of gas flow rate. The fracture strength of SiC layer increased from 450 MPa to 530 MPa by controlling the coating defects. An effort was made to develop the fundamental technology for the fuel element compact for use in High Temperature Gas-cooled Reactor(HTGR) through an establishment of fabrication process, required materials and process equipment as well as performing experiments to identify the basic process conditions and optimize them. Thermal load simulation and verification experiments were carried out for an assesment of the design feasibility of the irradiation rod. Out-of-pile testing of irradiation device such as measurement of pressure drop and vibration, endurance test was performed and the validity of its design was confirmed. A fuel performance analysis code, COPA has been developed to calculate the fuel temperature, the failure fractions of coated fuel particles, the release of fission products. The COPA code can be used to evaluate the performance of the high temperature reactor fuel under the reactor operation, irradiation, heating conditions. KAERI participated in the round robin test of IAEA CRP-6 program to characterize the diameter, sphericity, coating thickness, density and anisotropy of coated particles provided by Korea, USA and South Africa. QC technology was established for TRISO-coated fuel particle. A method for accurate measurement of the optical anisotropy factor for PyC layers of coated particles was developed. Technology and inspection procedures for density measurement of the coated particles was developed. The burn-leach technology for SiC defect inspection was developed.

    2007-02-15

    In this research, the remote handling technology was developed for the ACP application. The ACP gives a possible solution to reduce the rapidly cumulative amount of spent fuels generated from the nuclear power plants in Korea. The remote technologies developed in this work are a slitting device, a voloxidizer, a modified telescopic servo manipulator and a digital mock-up. A slitting device was developed to declad the spent fuel rod-cuts and collect the spent fuel UO{sub 2} pellets. A voloxidizer was developed to convert the spent fuel UO{sub 2} pellets obtained from the slitting process in to U{sub 3}O{sub 8} powder. Experiments were performed to test the capabilities and remote operation of the developed slitting device and voloxidizer by using simulated rod-cuts and fuel in the ACP hot cell. A telescopic servo manipulator was redesigned and manufactured improving the structure of the prototype. This servo manipulator was installed in the ACP hot cell, and the target module for maintenance of the process equipment was selected. The optimal procedures for remote operation were made through the maintenance tests by using the servo manipulator. The ACP digital mockup in a virtual environment was established to secure a reliability and safety of remote operation and maintenance. The simulation for the remote operation and maintenance was implemented and the operability was analyzed. A digital mockup about the preliminary conceptual design of an enginnering-scale ACP was established, and an analysis about a scale of facility and remote handling was accomplished. The real-time diagnostic technique was developed to detect the possible fault accidents of the slitting device. An assessment of radiation effect for various sensors was also conducted in the radiation environment.

  4. Recent developments in PET detector technology

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) is a tool for metabolic imaging that has been utilized since the earliest days of nuclear medicine. A key component of such imaging systems is the detector modules-an area of research and development with a long, rich history. Development of detectors for PET has often seen the migration of technologies, originally developed for high energy physics experiments, into prototype PET detectors. Of the many areas explored, some detector designs go on to be incorporated into prototype scanner systems and a few of these may go on to be seen in commercial scanners. There has been a steady, often very diverse development of prototype detectors, and the pace has accelerated with the increased use of PET in clinical studies (currently driven by PET/CT scanners) and the rapid proliferation of pre-clinical PET scanners for academic and commercial research applications. Most of these efforts are focused on scintillator-based detectors, although various alternatives continue to be considered. For example, wire chambers have been investigated many times over the years and more recently various solid-state devices have appeared in PET detector designs for very high spatial resolution applications. But even with scintillators, there have been a wide variety of designs and solutions investigated as developers search for solutions that offer very high spatial resolution, fast timing, high sensitivity and are yet cost effective. In this review, we will e cost effective. In this review, we will explore some of the recent developments in the quest for better PET detector technology. (topical review)

    1981-01-01

    This book is intended for those people who have a knowledge or understanding of rubber materials and processes but who wish to update their knowledge. It should be read in conjunction with Developments in Rubber Technology-l as that volume discussed developments in natural rubber and selected special purpose synthetic rubbers as well as additives. The authors have been selected for their expertise in each particular field and we, as editors, would like to express our appreciation to the individual authors and also to their companies. Such a book would be impossible to produce without such active cooperation as we have received. Volumes 1 and 2 of Developments in Rubber Technology cover rubbers which are processed and vulcanised in the traditional manner. It is appreciated that the omission of non-vulcanised rubber materials (the so­ called thermoplastic elastomers) will be unwelcome to many readers but it is intended, because of the size of the subject, to cover these materials in a subsequent volume.

  15. Chemical sensors technology development planning workshop

    International Nuclear Information System (INIS)

    The workshop participants were asked to: (1) Assess the current capabilities of chemical sensor technologies for addressing US Department of Energy (DOE) Environmental Restoration and Waste Management (EM) needs; (2) Estimate potential near term (one to two years) and intermediate term (three to five years) capabilities for addressing those needs; and (3) Generate a ranked list of specific recommendations on what research and development (R ampersand D) should be funded to provide the necessary capabilities. The needs were described in terms of two pervasive EM problems, the in situ determination of chlorinated volatile organic compounds (VOCs), and selected metals in various matrices at DOE sites. The R ampersand D recommendations were to be ranked according to the estimated likelihood that the product technology will be ready for application within the time frame it is needed and the estimated return on investment. The principal conclusions and recommendations of the workshop are as follows: Chemical sensors capable of in situ determinations can significantly reduce analytical costs; Chemical sensors have been developed for certain VOCs in gases and water but none are currently capable of in situ determination of VOCs in soils; The DOE need for in situ determination of metals in soils cannot be addressed with existing chemical sensors and the prospects for their availability in three to five years are uncertain; Adaptation, if necessary, and field application of laboratory analytical instruments and those few chemical sensors that are already in field testing is the best approach for the near term; The chemical sensor technology development plan should include balanced support for near- and intermediate-term efforts

  16. ["Directed perception", "mood", "social reinforcement". Sketches towards the historical semantics of Ludwik Fleck's Genesis and Development of a Scientific Fact].

    Science.gov (United States)

    Bauer, Julian

    2014-01-01

    This article analyses three basic concepts of Ludwik Fleck's Genesis and Development of a Scientific Fact. It shows first that Fleck's notion of "directed perception" is closely linked to Jakob von Uexküll's writings on the "Umwelt" of animals and humans. The article then proposes to regard the epistemological debates surrounding parapsychology as an important testing ground for the Fleckian concept of „mood“ and his concomitant hypotheses about „the tenacity of systems of opinion and the harmony of illusions". It finally argues that Fleck's modification of Wilhelm Jerusalem's idea of the "social consolidation" of knowledge helps us to understand the indebtedness of Fleck towards early functionalist sociology as well as his strong belief in "specific historical laws governing the development of ideas"The historical semantics of Fleck's works hence proves that his insights are neither marginal nor revolutionary but rather deeply rooted within scientific traditions from the late 19th and early 20th centuries.

    Full Text Available O presente estudo revisa o tema da representação dos fatos numéricos aditivos na memória de longo prazo em estudantes com transtornos de aprendizagem. A discussão de tais conceitos visa oferecer aos profissionais da área a possibilidade de revisão de práticas pedagógicas ligadas ao ensino. Trata-se [...] de um exame abrangente da literatura que indica que as crianças com transtornos de aprendizagem na matemática distinguem-se de seus pares em duas habilidades acadêmicas: utilizam procedimentos de contagem já abandonados por seus iguaisda mesma idade, e apresentam desenvolvimento tardio ou atípico na recuperação e/ou armazenamento dos fatos numéricos na memória. Como conclusão, sugere-sea estimulação dessas habilidades, a fim de evitar o aumento de dificuldades. Abstract in english This paper reviews the theme of representation of numerical additive facts in the long-term memory of students with learning disorders. These concepts have been addressed in the literature recently, and the discussion aims to offer education professionals the opportunity to review practices related [...] to teaching the basic facts. This is a comprehensive review of the literature on the subject. This review indicates that children with learning problems in mathematics are distinguished from their peers who have no difficulties in two well-defined academic skills: counting procedures tend to be evolutionarily more immature than those of their peers, and immature or atypical development of access or storage of numerical facts in memory seems to underlie this immature use. We conclude by suggesting stimulation of such skills to avoid increasing such difficulties.

    2003-01-01

    The Aerospace Corporation, NASA Glenn Research Center, Lockheed-Martin, and ILC Dover over the past two years have been engaged in developing a Multifunctional Inflatable Structure for the Powersphere Concept under contract with NASA (NAS3-01115). The Powersphere concept consists of a relatively large spherical solar array, which would be deployed from a microsatellite. The Powersphere structure and the deployment method was patented by the Aerospace Corporation (U.S. Patent Numbers 6,284,966 B 1 and 6,3 18,675). The work on this project has resulted in a number of technological innovations in the state of the art for integrating flexible thin-film solar cells with flex circuit harness technology and inflatable ultraviolet-light-rigidizable structures. The specific power, specific volume, for the Powersphere are presented in Figures 1 and 2 as a function of solar cell technology and efficiency. The Powersphere will enable microsatellite missions across NASA enterprises and DoD missions by providing ample electric power at an affordable cost. The Powersphere design provides attitude-independent electric power and thermal control for an enclosed microsatellite payload. The design is scalable, robust in high radiation environments and provides sufficient electric power to allow the use of electric propulsion. Electric propulsion enables precise positioning of microsatellites which is required for inspectors that would be deployed to inspect the International Space Station, Space Shuttle or large unmanned spacecraft. The Powersphere allows for efficient launch packaging versus deployed volume as shown in Figure 3.

  7. Development of Core Design Technology for LMR

    International Nuclear Information System (INIS)

    This report describes the contents of core design technology and computer code system development performed during 2005 and 2006 on the objects of nuclear proliferation resistant core and nuclear fuel basic key technology development security. Also, it is including the future application plans for the results and the developed methodology, important information and the materials acquired in this period. Two core designs with single enrichment were considered for the KALIMER-600 during the first year : 1) the first core uses the non-fuel rods such as B4C, ZrH1.8, and dummy rods, 2) the core using different cladding thickness for each core region (inner, middle, and outer cores) without non-fuel rods to flatten the power distribution. In particular, the latter design was intended to simplify the fuel assembly design by eliminating the heterogeneity. It was found that the proposed design satisfy all of the Gen IV SFR design goals on the cycle length longer than 18 EFPM, fuel discharge burnup larger than 80GWd/t, sodium void worth, conversion ratio, reactivity burnup swing and so on. For this object reactor, the structure integrity outside of reactor is confirmed for the radiation exposure during the plant life according to the result of shielding design and evaluation. The transmutation capability and the core characteristics of sodium cooled fast reactor was also evaluated according to the change of MA amount. The reactivity coefficients for the BN-600 reactor with MA fueled are calculated and the results are compared and evaluated with other participants results. Even though the discrepancies between the results of participants are somewhat large but the K-CORE results are close to the average within a standard deviation. To have the capability of 3-dimensional core dynamic analysis such as analyzing power distribution and reactivity variations according to the asymmetric insertion/withdrawal of control rods, the calculation module for core dynamic parameters was developed and programmed. The 1st order and exact perturbation theory calculation module to use in the TRI-Z geometry model was developed. The SFR inter-assembly core thermal flow analysis code MATCOM has been developed using the sub-channel code MATRA-LMR and the porous media code COMMIX-1AR/P. The analysis model for thermal creep, irradiation creep and the creep rupture strength characteristics for the Mod. HT9 were developed based on the available experiment data. To analyze the pin power distributions considering the influence of non-fuel pin inside fuel assembly, the form function concept was introduced and the program for the pin power calculation was develop

  8. Development of spent fuel remote handling technology

    International Nuclear Information System (INIS)

    In this research, the remote handling technology is developed for the advanced spent fuel conditioning process which gives a possible solution to deal with the rapidly increasing spent fuels. In detail, a fuel rod slitting device is developed for the decladding of the spent fuel. A series of experiments has been performed to find out the optimal condition of the spent fuel voloxidation which converts the UO2 pellet into U3O8 powder. The design requirements of the ACP equipment for hot test is established by analysing the modular requirement, radiation hardening and thermal protection of the process equipment, etc. The prototype of the servo manipulator is developed. The manipulator has an excellent performance in terms of the payload to weight ratio that is 30 % higher than that of existing manipulators. To provide reliability and safety of the ACP, the 3 dimensional graphic simulator is developed. Using the simulator the remote handling operation is simulated and as a result, the optimal layout of ACP is obtained. The supervisory control system is designed to control and monitor the several different unit processes. Also the failure monitoring system is developed to detect the possible accidents of the reduction reactor

    Energy security is a fundamental part of a country`s national security. Access to affordable, environmentally sustainable energy is a stabilizing force and is in the world community`s best interest. The current global energy situation however is not sustainable and has many complicating factors. The primary goal for government energy policy should be to provide stability and predictability to the market. This paper differentiates between short-term and long-term issues and argues that although the options for addressing the short-term issues are limited, there is an opportunity to alter the course of long-term energy stability and predictability through research and technology development. While reliance on foreign oil in the short term can be consistent with short-term energy security goals, there are sufficient long-term issues associated with fossil fuel use, in particular, as to require a long-term role for the federal government in funding research. The longer term issues fall into three categories. First, oil resources are finite and there is increasing world dependence on a limited number of suppliers. Second, the world demographics are changing dramatically and the emerging industrialized nations will have greater supply needs. Third, increasing attention to the environmental impacts of energy production and use will limit supply options. In addition to this global view, some of the changes occurring in the US domestic energy picture have implications that will encourage energy efficiency and new technology development. The paper concludes that technological innovation has provided a great benefit in the past and can continue to do so in the future if it is both channels toward a sustainable energy future and if it is committed to, and invested in, as a deliberate long-term policy option.

    The U.S. is the largest producer of mining products in the world. In 1999, U.S. mining operations produced $66.7 billion worth of raw materials that contributed a total of $533 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (a) Solid-solid separation (b) Solid-liquid separation (c) Chemical/Biological Extraction (d) Modeling and Control, and (e) Environmental Control. Distribution of funds is being handled via competitive solicitation of research proposals through Site Coordinators at the seven member universities. The first of these solicitations, referred to as the CAST II-Round 1 RFP, was issued on October 28, 2002. Thirty-eight proposals were received by the December 10, 2002 deadline for this RFP-eleven (11) Solid-Solid Separation, seven (7) Solid-Liquid Separation, ten (10) Chemical/Biological Extraction, six (6) Modeling & Control and four (4) Environmental Control. These were first reviewed and ranked by a group of technical reviewers (selected primarily from industry). Based on these reviews, and an assessment of overall program requirements, the CAST Technical Committee made an initial selection/ranking of proposals and forwarded these to the DOE/NETL Project Officer for final review and approval. This process took some 7 months to complete but 17 projects (one joint) were in place at the constituent universities (three at Virginia Tech, two at West Virginia University, three at University of Kentucky, three at University of Utah, three at Montana Tech, three at New Mexico Tech, and one at the University of Nevada, Reno) by May 17, 2003. These projects are listed by category, along with brief abstracts of their aims and objectives.

  12. Technology development needs summary, FY 1995

    International Nuclear Information System (INIS)

    Historic activities of DOE during the period of nuclear weapons development, and disposal practices of that time, resulted in the discharge of chemical and radioactive materials to the environment at many DOE facilities and sites. DOE has now focused a major technical effort on mitigating the effects of those discharges through an environmental restoration program. Since this could lead to prohibitive costs if conventional technology is applied for remedial action, a national program will be initiated to develop and demonstrate faster, better, cheaper, and safer means of restoring the DOE sites to conditions that will meet state and federal environment regulations. Key elements of the initiative are the Integrated Programs and Integrated Demonstrations, which work together to identify possible solutions to major environmental problems. Needed statements are given for the following programs: mixed waste landfill, uranium in soils, VOC-arid, decontamination and decommissioning of facilities, buried waste, characterization/monitoring/sensor technology, mixed waste, in situ remediation, efficient separations/processing, minimum additive waste stabilization, supercritical water oxidation. A section on how to get involved is included

    Abstract – High Temperature Gas-cooled Reactors (HTGRs) featuring particle fuel reached the stage of commercial deployment in the mid-1980s with the Fort St.Vrain and Thorium HochTemperatur Reaktor feeding electricity to the grids in the United States and West Germany, respectively. The technology was then adopted by Japan and China with the operation of the High Temperature Test Reactor in Oarai, Japan and the High Temperature Reactor (HTR-10) in China. Increasing the outlet temperature of the HTGR to even higher temperatures above 900°C will improve the thermodynamic efficiency of the system and enable application of a new class of gas reactor, the very high temperature reactor, to provide process heat, electricity, and hydrogen to chemical industries with the attendant benefits of improved energy security and reduced CO2 emissions. However, the increase in coolant outlet temperature presents a number of technical challenges associated with fuel, materials, power conversion, and analysis methods for the reactor and hydrogen production. The U.S. Department of Energy is sponsoring a broad program of research and development with a goal of addressing the technical challenges over a broad range of outlet temperatures as part of the Next Generation Nuclear Plant Project. This paper describes the research and development activities that are currently underway to realize the technologies needed for an HTGR that features outlet temperatures of 750 to 950°C.

  14. Development of key design technologies for STAR

    International Nuclear Information System (INIS)

    In first stage, the analysis of the ENSH core benchmark problem through the establishment of the computational codes and nuclear data libraries was performed and an independent design study of the ENHS cores by using ENDF/B-VI and JEF2.2 was performed. In second stage, the detailed core physics design of the reference ENHS cores through the various core calculations were performed to show that the core satisfies its design limits. For the fuel materials, the following four candidates has been considered : 1) Pu-U-10Zr fuel where the plutonium contents are typical for fast breeder reactor, 2) TRU-U-10Zr fuel 3) Pu (from TRU)-U-10Zr fuel, 4) TRU-TR-10Zr fuel. To resolve the thermal-hydraulic problems and develop the optimized system-dimensional design, the unique thermal-hydraulic model with 100% natural circulation capability was established. In addition, the experimental data and correlations on heat transfer characteristics of Pb or Pb-Bi eutectic were surveyed and rearranged to be applied into the thermal-hydraulic model of the STAR reactor. Using these data and thermal-hydraulic model the reactor dimension was optimized and the intermediate heat exchange system was developed and designed for the 100% natural circulation of the primary coolant. Experiments and analyses on material corrosion in liquid metal have been conducted. Also the oxygen control technology in liquid Pb-Bi for inhibition of the metal corrosion known as Russian technology, have been investigated through the literature review of material corrosion studies on liquid metal. In order to verify oxygen controllability with oxygen pemping and oxygen sensing with one-ended YSZ tube, a small-sized static cell has been developed. We also have developed a life prediction model based on corrosion rate data optained from literatures and experiment to evaluate the life time of structural material in Pb-Bi

    The National Aeronautics and Space Administration is developing battery and fuel cell technology to meet the expected energy storage needs of human exploration systems. Improving battery performance and safety for human missions enhances a number of exploration systems, including un-tethered extravehicular activity suits and transportation systems including landers and rovers. Similarly, improved fuel cell and electrolyzer systems can reduce mass and increase the reliability of electrical power, oxygen, and water generation for crewed vehicles, depots and outposts. To achieve this, NASA is developing non-flow-through proton-exchange-membrane fuel cell stacks, and electrolyzers coupled with low permeability membranes for high pressure operation. The primary advantage of this technology set is the reduction of ancillary parts in the balance-of-plant fewer pumps, separators and related components should result in fewer failure modes and hence a higher probability of achieving very reliable operation, and reduced parasitic power losses enable smaller reactant tanks and therefore systems with lower mass and volume. Key accomplishments over the past year include the fabrication and testing of several robust, small-scale non-flow-through fuel cell stacks that have demonstrated proof-of-concept. NASA is also developing advanced lithium-ion battery cells, targeting cell-level safety and very high specific energy and energy density. Key accomplishments include the development of silicon composite anodes, lithiatedmixed- metal-oxide cathodes, low-flammability electrolytes, and cell-incorporated safety devices that promise to substantially improve battery performance while providing a high level of safety.

  19. Development of Safety Analysis Technology for LMR

    International Nuclear Information System (INIS)

    In the safety analysis code system development area, the development of an analysis code for a flow blockage could be brought to completion throughout an integrated validation of MATRA-LMR-FB. The safety analysis code of SSC-K has been evolved by building detailed reactivity models and a core 3 dimensional T/H model into it, and developing its window version. A basic analysis module for SFR features also have been developed incorporating a numerical method, best estimated correlations, and a code structure module. For the analysis of the HCDA initiating phase, a sodium boiling model to be linked to SSC-K and a fuel transient performance/cladding failure model have been developed with a state-of-the-art study on the molten fuel movement models. Besides, scoping analysis models for the post-accident heat removal phase have been developed as well. In safety analysis area, the safety criteria for the KALIMER-600 have been set up, and an internal flow channel blockage and local faults have been analyzed for the assembly safety evaluation, while key safety concepts of the KALIMER-600 has been investigated getting through the analyses of ATWS as well as design basis accidents like TOP and LOF, from which the inherent safety due to a core reactivity feedback has been assessed. The HCDA analysis for the initiating phase and an estimation of the core energy release, subsequently, have been followed with setup of the safety criteria as well as T/H analysis for the core catcher. The thermal-hydraulic behaviors, and released radioactivity sources and dose rates in the containment have been analyzed for its performance evaluation in this area. The display of a data base for research products on the KALIMER Website and the detailed process planning with its status analysis, have become feasible from achievements in the area of the integrated technology development and establishment

    Formal specification development and modification are an essential component of the knowledge-based software life cycle. User interface technology is needed to empower end-users to create their own formal specifications. This paper describes the advanced user interface for AMPHION1 a knowledge-based software engineering system that targets scientific subroutine libraries. AMPHION is a generic, domain-independent architecture that is specialized to an application domain through a declarative domain theory. Formal specification development and reuse is made accessible to end-users through an intuitive graphical interface that provides semantic guidance in creating diagrams denoting formal specifications in an application domain. The diagrams also serve to document the specifications. Automatic deductive program synthesis ensures that end-user specifications are correctly implemented. The tables that drive AMPHION's user interface are automatically compiled from a domain theory; portions of the interface can be customized by the end-user. The user interface facilitates formal specification development by hiding syntactic details, such as logical notation. It also turns some of the barriers for end-user specification development associated with strongly typed formal languages into active sources of guidance, without restricting advanced users. The interface is especially suited for specification modification. AMPHION has been applied to the domain of solar system kinematics through the development of a declarative domain theory. Testing over six months with planetary scientists indicates that AMPHION's interactive specification acquisition paradigm enables users to develop, modify, and reuse specifications at least an order of magnitude more rapidly than manual program development.

    The effectiveness of catalyst performance is a function of the inlet exhaust gas temperature, gas flow rate, concentration of NO{sub x} and oxygen, and reductant quantity and species. Given this interrelationship, it becomes immediately clear that an integrated development approach is necessary. Such an approach is taken in this project. As such, the system development path is directed by an engine-catalyst engineering team. Of the tools at the engine engineer`s disposal the real-time aspects of computer assisted subsystem modeling is valuable. It will continue to be the case as ever more subtle improvements are needed to meet competitive performance, durability, and emission challenges. A review of recent prototype engines has shown that considerable improvements to base diesel engine technology are being made. For example, HSDI NO{sub x} has been reduced by a factor of two within the past ten years. However, additional substantial NO{sub x}/PM reduction is still required for the future. A viable lean NO{sub x} catalyst would be an attractive solution to this end. The results of recent high and low temperature catalyst developments were presented. High temperature base metal catalysts have been formulated to produce very good conversion efficiency and good thermal stability, albeit at temperatures near the upper range of diesel engine operation. Low temperature noble metal catalysts have been developed to provide performance of promising 4-way control but need increased NO{sub x} reduction efficiency.

  3. Development of advanced LWR fuel pellet technology

    International Nuclear Information System (INIS)

    A UO2 pellet was designed to have a grain size of larger than 12 ?m, and a new duplex design that UO2-Gd2O3 is in the core and UO2-Er2O3 in the periphery was proposed. A master mixing method was developed to make a uniform mixture of UO2 and additives. The open porosity of UO2 pellet was reduced by only mixing AUC-UO2 powder with ADU-UO2 or milled powder. Duplex compaction tools (die and punch) were designed and fabricated, and duplex compacting procedures were developed to fabricate the duplex BA pellet. In UO2 sintering, the relations between sintering variables (additive, sintering gas, sintering temperature) and pellet properties (density, grain size, pore size) were experimentally found. The UO2-U3O8 powder which is inherently not sinterable to high density could be sintered well with the aid of additives. U3O8 single crystals were added to UO2 powder, and homogeneous powder mixture was pressed and sintered in a reducing atmosphere. This technology leads to a large-grained pellet of 12-20 ?m. In UO2-Gd2O3 sintering, the relations between sintering variables (additives, sintering gas) and pellet properties (density, grain size) were experimentally found. The developed technology of fabricating a large-grained UO2 pellet has been optimized in a lab scale. Pellet properties were investigated in the fields of (1) creep properties, (2) thermal properties, (3) O/M ratios and (4) unit cell lattice. (author)

  9. Nuclear technology and the developing world

    International Nuclear Information System (INIS)

    The early 21st century has magnified the dangers posed by proliferation of weapons of mass destruction (WMD). Nonetheless, cooperative efforts to thwart this trade have grown considerably more difficult and the challenges more complicated. The ubiquitous nature of dual-use technology, the application of terrorist tactics for mass destruction on 9/11, the emergence of a more unilateralist US foreign policy, and the world's ever-expanding economic relations have all made more arduous the task of stemming proliferation of WMD, their precursors, and delivery systems. All of these challenges have been highlighted in recent years, but it is the last of these - the changing nature of the global economy- that is perhaps least analyzed but also most essential to improving international cooperation on nonproliferation. Many of today's proliferation concerns are familiar problems exacerbated by accelerating levels of international trade and investment. For example, controlling sensitive exports has become more complicated as officials, industry leaders, and nonproliferation experts must struggle simultaneously to find ways to ensure the flow of exports to legitimate buyers and supply chain partners who increasingly span the globe. Similarly, competitive enterprises today place a premium on rapid delivery and the speed of transactions. This in turn has increased pressures placed on officials around the world to reduce the time they spend evaluating each licensing decision, even aevaluating each licensing decision, even as these assessments become more difficult as global investors move deeper into the developing world. Furthermore, the emergence of developing economies as second-tier suppliers with the potential to transship critically sensitive technologies to third parties is another complicating factor and a consequence of the globalizing economy. Science, technology, and industry research and development activities with dual-use applications are also becoming increasingly international endeavors, facilitated through air travel, industry out sourcing, and intangible channels of communication such as the Internet. Simply put, as international borders become more porous as a result of free-trade arrangements, opportunities for proliferators multiply as well. Although the collection of information and intelligence to aid nonproliferation has become easier in a more open and transparent trade environment, efforts to stem proliferation have become more difficult as the means of acquiring and transporting nuclear and other WMD-related technologies have also multiplied. As these examples suggest, existing nonproliferation tools and export control mechanisms are not up to the task of dealing with new global economic realities. IAEA Director noted recently: 'The relative ease with which a multinational illicit network could be set up and operated demonstrates clearly the inadequacy of the present export control system.' Nor is it likely -absent substantial support from authorities in developing countries around the globe - that all of today's new proliferation channels can be effectively plugged. What is needed, therefore (and has long been recognized as essential by nonproliferation advocates) is a universal norm supporting nonproliferation. But how can this goal be achieved? As with much of today's discussion about globalization, the answer may lie in China. A credible proliferation control system is viewed in Beijing as a prerequisite to China becoming a high-tech economy. China also could play a more critical role in promoting international cooperative nonproliferation activities. It is incumbent even more so, however, on the international community to recognize, promote, and engage efforts by China and other developing States to institute improved trade controls, even though these are made in the countries' own national self interest. In this endeavor, the interests of the international community and the state intersect. Support for such activities should be given high priority in the IAEA's Technical Cooperation Programme and Nuclea

  10. Interactions of energy technology development and new energy exploitation with water technology development in China

    International Nuclear Information System (INIS)

    Interactions of energy policies with water technology development in China are investigated using a hybrid input-output model and scenario analysis. The implementation of energy policies and water technology development can produce co-benefits for each other. Water saving potential of energy technology development is much larger than that of new energy exploitation. From the viewpoint of proportions of water saving co-benefits of energy policies, energy sectors benefit the most. From the viewpoint of proportions of energy saving and CO2 mitigation co-benefits of water technology development, water sector benefits the most. Moreover, economic sectors are classified into four categories concerning co-benefits on water saving, energy saving and CO2 mitigation. Sectors in categories 1 and 2 have big direct co-benefits. Thus, they can take additional responsibility for water and energy saving and CO2 mitigation. If China implements life cycle materials management, sectors in category 3 can also take additional responsibility for water and energy saving and CO2 mitigation. Sectors in category 4 have few co-benefits from both direct and accumulative perspectives. Thus, putting additional responsibility on sectors in category 4 might produce pressure for their economic development. -- Highlights: ? Energy policies and water technology development can produce co-benefits for each other. ? For proportions of water saving co-benefits of energy policies, energy sectors benefit the most. ? For proportions of energy saving and CO2 mitigation co-benefits of water policy, water sector benefits the most. ? China’s economic sectors are classified into four categories for policy implementation at sector scale.

    Several new technologies for expansion of wavelength tunability and stabilization of laser system are developed. A self-seeded Ti:Sapphire laser system is developed in a dual cavity configuration to get a broad tunability in Near-IR region. For the continuous tunability in the visible region, mixing of dye solutions is demonstrated and this mixing provided the frequencies which is impossible in most of visible dye solutions. In addition an optical parametric oscillator (OPO) system, which adopted a BBO nonlinear crystal for the frequency tuning, is developed. This OPO system showed a bright future in solid state tunable laser technology. For the extension of tunability in UV region, a Raman shifter is developed. The frequency stability is achieved by using optogalvanic cell in a reference cavity, and 3% of stabilization is accomplished. 58 figs, 2 pix, 16 refs. (Author)

  12. Development of Long-lived radionuclide partitioning technology -Development of Long-lived radionuclide transmutation technology-

    International Nuclear Information System (INIS)

    This study has been focused on the development of an indigenous partitioning process by modifying and complementing the reported processes. First of all, we tried to approach several unit separation processes in order to identify their adoptability to the partitioning of long-lived radionuclides. There are several unit separation methods - adsorption, precipitation, ion exchange, and solvent extraction etc. which are often used in ore processing or metal purification processes. With the unit processes chosen in this study, the following experiments have been carried out to provide technical facts necessary to develop a partitioning process. (1) Removal of a small amount of uranium by extraction with TBP from simulated waste solution (2) Destruction of nitric acid by use of formic acid (3) Co-precipitation of minor actinides and lanthanides. (4) Partitioning of minor actinides and lanthanides by extraction with HDEHP (5) Partitioning of minor actinides and lanthanides by ion exchange

    Mack, J. C.

    1983-01-01

    Testing of a U.S. Army XCH-62 HLH aft rotor transmission under NASA Contract NAS 3-22143 was successfully completed. This test establishes the feasibility of large, high power rotorcraft transmissions as well as demonstrating the resolution of deficiencies identified during the HLH advanced technology programs and reported by USAAMRDLTR-77-38. Over 100 hours of testing was conducted. At the 100% design power rating of 10,620 horsepower, the power transferred through a single spiral bevel gear mesh is more than twice that of current helicopter bevel gearing. In the original design of these gears, industry-wide design methods were employed and failures were experienced which identified problem areas unique to gear size. To remedy this technology shortfall, a program was developed to predict gear stresses using finite element analysis for complete and accurate representation of the gear tooth and supporting structure. To validate the finite element methodology gear strain data from the existing U.S. Army HLH aft transmission was acquired, and existing data from smaller gears were made available.

  19. Development of salt waste treatment technology

    International Nuclear Information System (INIS)

    To develop a proper waste conditioning technology for salt wastes, alpha- contaminated organic wastes, and long-lived fission products, which are presumed to generate from the pyrochemical dry processing of spent fuel, researches on LiCl salt waste treatment (including salt fixation, ion exchange of radionuclides and salt pre-treatment technique), molten salt oxidation of organic alpha wastes and recovery of radioiodine have been performed. In a research on the waste LiCl salt treatment, the characterization on a salt-loaded zeolite sample, prepared by an immobilization of the molten LiCl salt waste with zeolite A, suggested that an optimum mixing ratio, r (=LiCl/zeolite) was 1.0. Pre-treatment of salt waste was performed via gelation reaction with additives of phosphate and sodium silicate. Characteristics of the gel product after drying and thermal treatment were tested and evaluated to establish the proper reaction conditions on the conversion of salt waste into durable waste forms. Molten salt oxidation (MSO) is selected as the most promising technology for the treatment of alpha-contaminated waste, and its lab-scale test and theoretical model study revealed its good effectiveness in the treatment of the problematic waste, such as halogenated organics including toxic and radioactive metals. The optimal conditions to effectively recover iodine from silver ion- exchanged adsorbent(AgX) was established and confirmed through experiment using radioiodine tracer. Fundamental data for conversion the recovered iodine to target material powder of NaI were obtained

  1. Fabrication issues and technology development for HELEOS

    International Nuclear Information System (INIS)

    Starfire is a joint railgun of Lawrence Livermore National Laboratory and Sandia National Laboratory-Albuquerque. The goal of Starfire is to develop a Hypervelocity Electromagnetic Launcher for Equation of State (HELEOS) experiments. A two-stage light-gas gun is used as a pre-injector. Each round-bore HELEOS railgun module is 12.7 mm in diameter and 2.4 m long. The muzzle end of the railgun is connected to a vacuum tank. Common materials and fabrication technology are used in the manufacture of all components, and modular design allows for extending the length of the railgun as progress dictates. The launcher uses a ''vee block'' geometry, which is designed to: (1) provide compressive preload, (2) operate with a 300-MPa (3-kbar) internal bore pressure, and (3) easily accommodate interchangeable materials in the bore support structure and rail. The authors have performed full-scale material testing of the railgun and have developed a precision round-bore fabrication process. Air-gage inspection is used to determine bore diameter and straightness. They have also developed a surface mapping system to document the surface topography of the bore before and after an experiment. This paper presents fabrication details, results of tests conducted, and areas for potential improvement

  2. Development of Advanced LWR Fuel Pellet Technology

    International Nuclear Information System (INIS)

    Nuclear fuel (UO2) pellets play important roles in not only generating heat through fission but also trapping fission products. The fuel burnup tends to increases in order to improve fuel economy. As the burn-up increases, the trapping capacity of pellets decreases and thus the rod internal pressure becomes higher. Accordingly, the performance of fuel rod will be degraded. In order to resolve this problem, it is essential to develop or to ameliorate pellet materials. More specifically, it is important to develop large-grained UO2 pellets. A longer fuel cycle which is needed to enhance the load factor of a nuclear power plant requires new burnable absorber with adequate nuclear performance. Burnable absorber used in our country is having been imported, so the technology related to burnable absorber is behind in our country. It is necessary to develop new burnable absorber for the purpose of reducing the power peaking and residual penalty of the reactor core in longer fuel cycles

  3. Development of decommissioning system engineering technology

    International Nuclear Information System (INIS)

    In the decommissioning planning stage, it is important to select the optimized decommissioning process considering the cost and safety. Especially the selection of the optimized decommissioning process is necessary because it affects to improve worker's safety and decommissioning work efficiency. The decommissioning process evaluation technology can provide the optimized decommissioning process as constructing various decommissioning scenarios and it can help to prevent the potential accidents as delivering the exact work procedures to workers and to help workers to perform decommissioning work skillfully. It's necessary to measure the radioactive contamination in the highly contaminated facilities such as hot-cells or glove-boxes to be decommissioned for decommissioning planning. These facilities are very high radiation level, so it is difficult to approach. In this case the detector system is preferable to separate the sensor and electronics, which have to locate in the facility outside to avoid the electric noise and worker's radiation exposure. In this project, we developed the remote detection system for radiation measurement and signal transmission in the high radiation area. In order to minimize worker's exposure when decommissioning highly activated nuclear facilities, it is necessary to develop the remote handling tool to perform the dismantling work remotely. Especially, since cutting, measuring, and decontamination works should be performed remotely in the highly activated area, the remote handling tool for conducting these works should be developed. Therefore, the multi-purpose dismantling machine that can measuring dose, facility cutting, and remote handling for maintenance and decommissioning of highly activated facility should be needed

  8. Development of Coated Particle Fuel Technology

    International Nuclear Information System (INIS)

    UO2 kernel fabrication technology was developed at the lab sacle(20?30g-UO2/batch). The GSP technique, modified method of sol-gel process, was used in the preparation of spherical ADU gel particle and these particles were converted to UO3 and UO2 phases in calcination furnace and sintering furnace respectively. Based on the process variables optimized using simulant kernels in 1-2 inch beds, SiC TRISO-coated particles were fabricated using UO2 kernel. Power densities of TRISO coated particle fuels and gamma heat of the tubes are calculated as functions of vertical location of the fuel specimen in the irradiation holes by using core physics codes, MCNP and Helios. A finite model was developed for the calculations of temperatures and stresses of the specimen and the irradiation tubes. Dimensions of the test tubes are determined based on the temperatures and stresses as well as the gamma heat generated at the given condition. 9 modules of the COPA code (MECH, FAIL, TEMTR, TEMBL, TEMPEB, FPREL, MPRO, BURN, ABAQ), the MECH, FAIL, TEMTR, TEMBL, TEMPEB, and FPREL were developed. The COPA-FPREL was verified through IAEA CRP-6 accident benchmarking problems. KAERI participated in the round robin test of IAEA CRP-6 program to characterize the diameter, sphericity, coating thickness, density and anisotropy of coated particles provided by Korea, USA and South Africa. The inspection and test plan describing specifications and inspection method of coated particles was developed to confirm the quality standard of coated particles. The quality inspection instructions were developed for the inspection of coated particles by particle size analyzer, density inspection of coating layers by density gradient column, coating thickness inspection by X-ray, and inspection of optical anistropy factor of PyC layer. The quality control system for the TRISO-coated particle fuel was derived based on the status of quality control systems of other countries

  13. New Technologies and Sustainable Development of Industry

    International Nuclear Information System (INIS)

    The present technology assessment study examines the effects of three technology scenarios on future energy consumption and the energy-related emissions by industrial manufacturing in Switzerland. The three paths of development (Trend, High-Tech, Alternative) can be represented as follows: After a reduction until 2015, the Trend development entails a slight increase in consumption of energy. Until then consumption is some 10 percent lower in both the High-Tech and the Alternative Scenarios. Consumption of electricity increases in all scenarios, the proportion is highest in 20 year's time under the High-Tech scenario. SO2 and CO2 emissions decrease in all scenarios until 2000 and then level out at a low level. The emissions are lowest in the High-Tech scenario. In contrast the NOx and the VOC emissions diminish until 2000 and then rise again continuously. At this juncture important bases are still not yet available for a definitive evaluation with respect to the sustainable development. Sustainability objectives are currently being compiled for Switzerland in the wake of the Berlin Climate Conference and the Rio Conference. In the political lobbies the Green factions are making demands, such as those currently under discussion internationally (e.g. CO2 reductions on a scale of some 80 percent by 2050), whereas conservative and industrial circle representatives support the objective of sustainable development but reject a quantification of objectives. The official objectives of the Swiss Energy 2000 programme can be achieved with all scenarios. With the High-Tech and Alternative scenarios, concepts of a reduction in CO2 by 20 percent by 2015 (as currently under discussion in Switzerland), are realistic. However, further energy-relevant efficiency potentials in industrial production can be activated by energy-policy motivated measures. More extensive objectives, such as e.g. a CO2 reduction of 50 percent, are hardly attainable, even in the long-term, without sufficiency considerations in industrial production. The degree of acceptance of measures diminishes on the conservative and business sides with increasing interventionism whereas the Green lobby would put up with direct guidance measures and, above all, negative effects on the Swiss labour market.

  15. Decision Gate Process for Assessment of a Technology Development Portfolio

    Science.gov (United States)

    Kohli, Rajiv; Fishman, Julianna; Hyatt, Mark

    2012-01-01

    The NASA Dust Management Project (DMP) was established to provide technologies (to TRL 6 development level) required to address adverse effects of lunar dust to humans and to exploration systems and equipment, which will reduce life cycle cost and risk, and will increase the probability of sustainable and successful lunar missions. The technology portfolio of DMP consisted of different categories of technologies whose final product is either a technology solution in itself, or one that contributes toward a dust mitigation strategy for a particular application. A Decision Gate Process (DGP) was developed to assess and validate the achievement and priority of the dust mitigation technologies as the technologies progress through the development cycle. The DGP was part of continuous technology assessment and was a critical element of DMP risk management. At the core of the process were technology-specific criteria developed to measure the success of each DMP technology in attaining the technology readiness levels assigned to each decision gate. The DGP accounts for both categories of technologies and qualifies the technology progression from technology development tasks to application areas. The process provided opportunities to validate performance, as well as to identify non-performance in time to adjust resources and direction. This paper describes the overall philosophy of the DGP and the methodology for implementation for DMP, and describes the method for defining the technology evaluation criteria. The process is illustrated by example of an application to a specific DMP technology.

  16. Energy Choices. Choices for future technology development

    International Nuclear Information System (INIS)

    In the next few years political decisions lie ahead in Sweden and the EU regarding the detailed formulation of the EU's so-called 20-20-20 targets and accompanying EU directives. Talks on a new international post-2012 climate agreement are imminent. The EU targets involve reducing emissions of greenhouse gases by 20 per cent, increasing the proportion of renewable energy by 20 per cent and improving energy efficiency by 20 per cent - all by the year 2020. According to the analysis of the consequences of the targets that the Technology Development Group has commissioned, the reduction in carbon dioxide in the stationary energy system in the Nordic region will be 40 per cent, not 20 per cent, if all the EU targets are to be achieved. The biggest socio-economic cost is associated with achieving the efficiency target, followed by the costs associated with achieving the renewable energy target and the CO2 target. On the basis of this analysis and compilations about technology development, we want to highlight the following important key issues: Does Sweden want to have the option of nuclear power in the future or not? How to choose good policy instruments for new electricity production and networks? How best to reduce the carbon dioxide emissions of the transport sector and how to develop control and incentive measures that promote such a development? We are proposing the following: Carry out a more in-depth analysis of the consequences of the EU targets, so that the policy instruments produce the best combination as regards climate, economy and security of supply. To achieve the EU targets would require large investments in electricity production, particularly renewable energy, and in electricity networks. Internationally harmonized policy instruments and other incentive measures are required in order for the necessary investments to take place. The policy instruments have to provide a level playing field for all players in the energy sector. The large investments will present Swedish industry with a good opportunity to develop new technology and new system solutions. Speed up the permitting processes for plants and energy production and electricity networks. Prepare a long-term plan regarding decisions on strengthening the electricity networks, as well as a time schedule for associated decisions and processes. Furthermore, a joint plan regarding foreign connections should be developed for the Nordic region. Lobby for an EU-wide certificate system for renewable energy. The EU target on renewable energy will result in improved opportunities for Sweden to export electricity, but the certificate system currently in force in Sweden will result in the future surplus in electricity production being paid for by Swedish electricity customers. Carry out an immediate change in legislation to facilitate planning for new nuclear power. This is necessary if Sweden wants to replace electricity production from the two oldest nuclear power plants, which may have to close around 2020- 2025 for financial reasons. Power companies need to plan their investments and the safety authorities need to make their preparations. Since other existing nuclear power plants will be decommissioned on a relatively frequent basis in the period 2035-2045, there are even more reasons to keep open the option of new nuclear power. Invest heavily in Sweden in research, development, demonstration and implementation of new technology and systems in several areas. Swedish companies and universities should continue their investments in the area of CCS (capture and storage of carbon dioxide). This is necessary in order for it to be possible to evaluate the consequences of the technology for Sweden and its usefulness and safety in the longer term. A breakthrough is envisaged after 2020 and will in the first instance concern CCS at power stations, but CCS may also be applied to large point sources of carbon dioxide emissions from energy intensive industry. Formulate a national vision for plug-in hybrids and electric cars in Sweden. According to the proposal from the Energ

  17. Development of a Remote Monitoring System Using Meteor Burst Technology

    International Nuclear Information System (INIS)

    Monitoring the cleanup and closure of contaminated sites requires extensive data acquisition, processing, and storage. At remote sites, the task of monitoring often becomes problematical due to the lack of site infrastructure (i.e., electrical power lines, telephone lines, etc.). MSE Technology Applications, Inc. (MSE) has designed an economical and efficient remote monitoring system that will handle large amounts of data; process the data, if necessary; and transmit this data over long distances. Design criteria MSE considered during the development of the remote monitoring system included: the ability to handle multiple, remote sampling points with independent sampling frequencies; robust (i.e., less susceptible to moisture, heat, and cold extremes); independent of infrastructure; user friendly; economical; and easy to expand system capabilities. MSE installed and tested a prototype system at the Mike Mansfield Advanced Technology Center (MMATC), Butte, Montana, in June 2005. The system MSE designed and installed consisted of a 'master' control station and two remote 'slave' stations. Data acquired at the two slave stations were transmitted to the master control station, which then transmits a complete data package to a ground station using meteor burst technology. The meteor burst technology has no need for hardwired land-lines or man-made satellites. Instead, it uses ionized particles in the Earth's atmosphere to propagate a radio signal. One major advantage of th a radio signal. One major advantage of the system is that it can be configured to accept data from virtually any type of device, so long as the signal from the device can be read and recorded by a standard data-logger. In fact, MSE has designed and built an electrical resistivity monitoring system that will be powered and controlled by the meteor burst system components. As sites move through the process of remediation and eventual closure, monitoring provides data vital to the successful long term management of the site. The remote monitoring system developed by MSE is cost effective, robust, and can easily be integrated into a site monitoring plan yet remains independent of other site activities/infrastructure and is expandable to meet future site monitoring requirements.

    Technology stimulates output and creates new demand. The introduction of new technologies usually causes an increase in investments, which creates more jobs in companies that produce capital goods. Competition occurs as a function of output quality. On the other hand, technology reduces costs by increasing efficiency in regard to output. This leads to one of three effects: the prices of the denoted products or services decrease, the wages in industries that apply new technologies increase, an...

    Fuel cells have the prospect for exploiting fossil fuels more benignly and more efficiently than alterantives. The various types represent quite different technologies, with no clear winner, yet. Nevertheless, the high temperature MCFC and solid oxide fuel cell (SOFC) types seem better suited to power generation in a hydrocarbon fuel economy. Presently, the costs of MCFCs and SOFCs are too high to compete directly with contemporary power generation plant. Seeking to overcome the drawbacks of first generation fuel cells, over the past 7 years an innovative second generation SOFC concept has been evolved in the Rolls-Royce Strategic Research Centre, with encouraging results. It is distinguished from other types by the name: Integrated Planar Solid Oxide Fuel Cell (IP-SOFC). It is a family of integrated system concepts supporting product flexibility with evolutionary stretch potential from a common SOFC module. Fabrication of the key component of the IP-SOFC, the 'multi-cell membrane electrode assembly (multi-cell MEA) module' carrying many series connected cells with supported electrolyte membranes only 10 to 20 {mu}m thick, has been proved. Development of the internal reforming subsystem, the next big hurdle, is now in hand.

    For an efficient production of nuclear hydrogen, the VHTR (Very High Temperature Gas-cooled Reactor) of 950 .deg. C outlet temperature and the interfacing system for the hydrogen production are required. We have developed various evaluation technologies for the performance and safety of VHTR through the accomplishment of this project. First, to evaluate the performance of VHTR, a series of analyses has been performed such as core characteristics at 950 .deg. C, applicability of cooled-vessel, intermediate loop system and high temperature structural integrity. Through the analyses of major accidents such as HPCC and LPCC and the analysis of the risk/performance-informed method, VHTR safety evaluation has been also performed. In addition, various design analysis codes have been developed for a nuclear design, system loop design, system performance analysis, air-ingress accident analysis, fission product/tritium transport analysis, graphite structure seismic analysis and hydrogen explosion analysis, and they are being verified and validated through a lot of international collaborations

    NASA Glenn Research Center is sponsoring efforts to develop technology for high-performance, high-density, low-freezing point, low-hazards monopropellant systems. The program is focused on a family of monopropellant formulations composed of an aqueous solution of hydroxylammonium nitrate (HAN) and a fuel component. HAN-based monopropellants offer significant mass and volume savings to small (less than 100 kg) satellite for orbit raising and on-orbit propulsion applications. The low-hazards characteristics of HAN-based monopropellants make them attractive for applications where ground processing costs are a significant concern. A 1-lbf thruster has been demonstrated to a 20-kg satellite orbit insertion duty cycle, using a formulation compatible with currently available catalysts. To achieve specific impulse levels above those of hydrazine, catalyst materials that can withstand the high-temperature, corrosive combustion environment of HAN-based monopropellants have to be developed. There also needs to be work done to characterize propellant properties, burning behavior, and material compatibility. NASA is coordinating their monopropellant efforts with those of the United States Air Force.

  8. Definition of Technology Readiness Levels for Transmutation Fuel Development

    International Nuclear Information System (INIS)

    To quantitatively assess the maturity of a given technology, the Technology Readiness Level (TRL) process is used. The TRL process has been developed and successfully used by the Department of Defense (DOD) for development and deployment of new technology and systems for defense applications. In addition, NASA has also successfully used the TRL process to develop and deploy new systems for space applications. Transmutation fuel development is a critical technology needed for closing the nuclear fuel cycle. Because the deployment of a new nuclear fuel forms requires a lengthy and expensive research, development, and demonstration program, applying the TRL concept to the transmutation fuel development program is very useful as a management and tracking tool.

    Wolsong Unit 1 as the first heavy water reactor in Korea has been in service for 17 years since 1983. It would be about the time to prepare a plan for the solution of problems due to aging of the reactor. The aging of CANDU reactor could lead especially to the steam generator cruding and pressure tube sagging and creep and then decreases the operation margin to make some problems on reactor operations and safety. The counterplan could be made in two ways. One is to repair or modify reactor itself. The other is to develop new advanced fuel to increase of CANDU operation margin effectively, so as to compensate the reduced operation margin. Therefore, the first objectives in the present R and D is to develop the CANFLEX-NU(CANDU Flexible fuelling-Natural Uranium) fuel as a CANDU advanced fuel. One of the improvements in CANDU fuel fabrication technology, and advanced method of Zr-Be brazing was developed. For the formation of Zr-Be alloy, preheating and main heating temperature in the furnace is 700 deg C, 1200 deg C respectively. In order to find an appropriate material for the brazing joints in the CANDU fuel, the composition of Zr based amorphous metals were designed. And, the effect of hydrogen on the mechanical properties of cladding sheath and feasibility of the eddy current test to evaluate quality of end cap weld were also studied for the fundamental research purpose. As a preliminary study to suggest optimal way for the mass production of CANFLEX-NU fuel at KNFC the existing CANDU fuel facilities and fabrication/inspection processes were reviewed. The best way is that the current CANDU facility shall be modified to produce small diametrial CANFLEX elements and a new facility shall be constructed to produce large diametrial CANFLEX fuel elements. 46 refs., 99 figs., 10 tabs.

  14. Cellulosic ethanol. Potential, technology and development status

    Energy Technology Data Exchange (ETDEWEB)

    Rarbach, M. [Sued-Chemie AG, Muenchen (Germany)

    2012-07-01

    In times of rising oil prices and a growing energy demand, sustainable alternative energy sources are needed. Cellulosic ethanol is a sustainable biofuel, made from lignocellulosic feedstock such as agricultural residues (corn stover, cereal straw, bagasse) or dedicated energy crops. Its production is almost carbon neutral, doesn't compete with food or feed production and induces no land use changes. It constitutes a new energy source using an already existing renewable feedstock without needing any further production capacity and can thus play a major role on the way to more sustainability in transport and the chemical industry and reducing the dependence on the import of fossil resources. The potential for cellulosic ethanol is huge: In the US, the annual production of agricultural residues (cereal straw and corn stover) reached almost 384 million tons in 2009 and Brazil alone produced more than 670 million tons of sugar cane in 2009 yielding more than 100 million tons of bagasse (dry basis). And alone in the European Union, almost 300 million tons of crop straw are produced annually. The last years have seen success in the development and deployment in the field of cellulosic ethanol production. The main challenge thereby remains to demonstrate that the technology is economically feasible for the up-scaling to industrial scale. Clariant has developed the sunliquid {sup registered} process, a proprietary cellulosic ethanol technology that reaches highest greenhouse gas (GHG) emission savings while cutting production costs to a minimum. The sunliquid {sup registered} process for cellulosic ethanol matches the ambitious targets for economically and ecologically sustainable production and greenhouse gas reduction. It was developed using an integrated design concept. Highly optimized, feedstock and process specific biocatalysts and microorganisms ensure a highly efficient process with improved yields and feedstock-driven production costs. Integrated, on-site enzyme production further reduces production costs substantially and assures independence from external suppliers. Aproprietary and innovative ethanol separation method cuts energy demand by up to 50% compared to standard distillation. Thus, the energy derived from the byproducts like lignin and fermentation meet the entire electricity and heat demand of the production process, leading to close to 100% GHG reductions of the resulting ethanol. In July 2011 construction started on a demonstration plant with an annual ethanol output of 1,000 tons. The plant started into operation in July 2012. It will demonstrate the economic competitiveness to first generation processes and constitutes the last step from laboratory to commercial production. Additionally, the technology opens up a pathway to a second generation sugar platform to ultimately produce green chemicals for a wide range of applications, e.g. organic acids (lactic acid, succinic acid..), green solvents, C4 alcohols, furfural or furfuryl alcohol and their derivates or other specialty and bulk chemicals which can be further converted into biobased plastics and polymers.

  15. Development of germline manipulation technologies in livestock

    International Nuclear Information System (INIS)

    Breeding, based on conventional selection, has been the mainstay for livestock genetic improvement for more than 70 years, and is still so today. Sophisticated statistical and computing tools now enhance conventional genetic selection, nevertheless traits such as fertility and disease resistance have still proved difficult to improve. Gene transfer technology (transgenesis) offers the potential, as yet unproven, to modify these types of traits. A transgenic animal carries integrated DNA sequences in its genome. The introduced DNA can be derived from species other than the host and can be modified in vitro prior to being introduced into the germline. Therefore, transgenic livestock overcome some of the limitations of classical animal breeding regimes, where importation of genes by crossbreeding is limited to those traits already present within a given species. The most used method for introducing genes into the germline of animals involves the direct microinjection of DNA into the pronuclei of fertilised eggs. Pronuclear microinjection, although conceptually simple - a fine needle is used to pierce the pronucleus and the DNA is injected - requires special equipment and considerable dexterity on behalf of the person involved. By adapting the techniques employed for gene transfer in mice, pronuclear microinjection has been used to generate transgenic farm animals. The first attempts to genetically modify livestock owe much to pioneering experiments in mice, where the intneering experiments in mice, where the introduction of growth hormone gene dramatically increased the growth rate and final size of the animals. By contrast, the same approaches in livestock did not prove successful. Indeed, in terms of modifying livestock for agricultural purposes, most of the early expectations were not realised. Rather, it has been the development of novel uses of livestock, particularly for human medicine, that has led the way and advanced this technology. The majority of transgenic livestock have been produced using this method but it only allows gene addition. For gene removal the integration of the introduced transgene has to be targeted to the gene of interest. This requires a relatively high frequency of homologous recombination that occurs in embryonic stem (ES) cells. Thus the desired genetic modification can be identified and selected for while the cells are grown in culture. This enables vastly more sophisticated genetic changes to be engineered, including gene knock-out. Unfortunately, ES cells have only been isolated for mice and even in this species there are only a few permissive strains. The lack of methods for gene knock-out in livestock was the driving force leading to the development of nuclear transfer technology. This technique was made famous through the generation of 'Dolly'. It is fair to say that although catching both the scientific and media in a frenzy of cloning issues, perhaps the greatest legacy of nuclear transfer will be the development of cell based therapeutic strategies based on stem and somatic cells to treat human genetic diseases. Although 'Dolly' is not herself transgenic, this technique does offer the potential to make transgenic animals more efficiently than by using the pronuclear microinjection method. This is primarily because all founder animals are transgenic and a flock/herd of clonal animals can be produced within one generation. More importantly, nuclear transfer uses cells grown in culture therefore, for the first time, allows precise changes to the germline of ruminants to be attempted. This has now been shown to be possible, a sheep carrying a disruption of the PrP gene, a targeted insertion into the collagen gene and pigs that have a deletion of the galactosyltransferase gene having been produced. However, the generation of knockout transgenic livestock is a hugely demanding technical and financial undertaking. First, the techniques utilised efficiently in mice, do work in livestock cells but are considerably less effective. Second, the stringent selection and extended in vitro culture

    The objective of the development of severe accident analysis technology is to understand the severe accident phenomena such as core melt progression and to provide a reliable analytical tool to assess severe accidents in a nuclear power plant. Furthermore, establishment of the accident management strategies for the prevention/mitigation of severe accidents is also the purpose of this research. The study may be categorized into three areas. For the first area, two specific issues were reviewed to identify the further research direction, that is the natural circulation in the reactor coolant system and the fuel-coolant interaction as an in-vessel and an ex-vessel phenomenological study. For the second area, the MELCOR and the CONTAIN codes have been upgraded, and a validation calculation of the MELCOR has been performed for the PHEBUS-B9+ experiment. Finally, the experimental program has been established for the in-vessel and the ex-vessel severe accident phenomena with the in-pile test loop in KMRR and the integral containment test facilities, respectively.

  5. Decontamination Technology Development for Nuclear Research Facilities

    International Nuclear Information System (INIS)

    The originative CO2 pellet blasting equipment was developed by improving additional components such as feed screw, idle roller and air-lock feeder to clear up the problems of freezing and discontinuity of blasting and by adopting pneumatically operated vacuum suction head and vacuum cup to prevent recontamination by collecting contaminant particulates simultaneously with the decontamination. The optimum decontamination process was established according to the kind of materials such as metal, concrete and plastic and the type of contaminants such as particulate, fixed chemical compound and oil. An excellent decontamination performances were verified by means of the lab-scale hot test with radioactive specimen and the technology demonstration in IMEF hot cell. The PFC dry decontamination equipment applicable to the surface contaminated with high radioactive particulate was developed. This equipment consists of the unit processes such as spray, collection, filtration and dry distillation designed originatively applicable to inside of dry hot cell. Through the demonstration of PFC spray decontamination process in IMEF hot cell, we secured on-site applicability and the decontamination efficiency more than 90 %. We investigated the characteristics of dismantled metal waste melting and the radionuclide(Co, Cs, U) distribution into ingot and slag by melting decontamination experiments using electric arc melter. We obtained the decontamination factors greater than 100 for Cs and of 10?100 for uranium. The pilot scale(200 kg/batch) demonstration for melting decontamination was carried out successfully using high temperature melting facility at KAERI. The volume reduction factor of 1/7 and the economical feasibility of the melting decontamination were verified.

    1997-08-01

    The Department of Energy (DOE) established the Mixed Waste Characterization, Treatment, and Disposal Focus Area (MWFA) to develop technologies required to meet the Department`s commitments for treatment of mixed low-level and transuranic wastes. Waste treatment includes all necessary steps from generation through disposal. Systems engineering was employed to reduce programmatic risk, that is, risk of failure to meet technical commitments within cost and schedule. Customer needs (technology deficiencies) are identified from Site Treatment Plans, Consent Orders, ten year plans, Site Technical Coordinating Groups, Stakeholders, and Site Visits. The Technical Baseline, a prioritized list of technology deficiencies, forms the basis for determining which technology development activities will be supported by the MWFA. Technology Development Requirements Documents are prepared for each technology selected for development. After technologies have been successfully developed and demonstrated, they are documented in a Technology Performance Report. The Technology Performance Reports are available to any of the customers or potential users of the technology, thus closing the loop between problem identification and product development. This systematic approach to technology development and its effectiveness after 3 years is discussed in this paper.

  15. DOE International Technology Exchange Program (ITEP): Technical integration of sensor technology development

    International Nuclear Information System (INIS)

    To achieve the goal of remediating waste sites throughout its complex and of bringing its facilities into full compliance by the year 2019, the DOE has established the Office of Environmental Restoration and Waste Management (E). Within E, the Office of Technology Development (OTD) has been created to develop technologies that will support DOE's cleanup goal. The OTD is accelerating remediation technology application by leveraging the expenditure of available funds through international technology development and demonstration projects. These projects will address EM's environmental restoration and waste management needs. For this reason, the OTD has created the International Technology Exchange Program (ITEP) whose primary objective is to effect collaboration among governments, industries, and educational institutions to identify worldwide technologies suitable for this purpose. These technologies should also meet US commercial needs. The ITEP will also serve as a mechanism for transferring technologies developed under DOE sponsorship to US industry for ultimate application in the international arena

  16. Hanford Technology Development (Tank Farms) - 12509

    International Nuclear Information System (INIS)

    The mission of the Department of Energy's Office of River Protection (ORP) is to safely retrieve and treat the 56 million gallons of Hanford's tank waste and close the Tank Farms to protect the Columbia River. The millions of gallons of tank waste are a byproduct of decades of plutonium production. After irradiated fuel rods were taken from the nuclear reactors to the processing facilities at Hanford they were exposed to a series of chemicals designed to dissolve away the rod, which enabled workers to retrieve the plutonium. Once those chemicals were exposed to the fuel rods they became radioactive and extremely hot. They also couldn't be used in this process more than once. Because the chemicals are caustic and extremely hazardous to humans and the environment, underground storage tanks were built to hold these chemicals until a more permanent solution could be found. One key part of the ongoing work at Hanford is retrieving waste from the single-shell tanks, some of which have leaked in the past, and transferring that waste to the double-shell tanks - none of which have ever leaked. The 56 million gallons of radioactive tank waste is stored in 177 underground tanks, 149 of which are single-shell tanks built between 1943 and 1964. The tanks sit approximately 250 feet above the water table. Hanford's single-shell tanks are decades past their 20-year design life. In the past, up to 67 of the single-shell tanks are known or suspected to have leaked as much as one million gallons of waste to the surrounding soil. Starting in the late 1950's, waste leaks from dozens of the single-shell tanks were detected or suspected. Most of the waste is in the soil around the tanks, but some of this waste is thought to have reached groundwater. The Vadose Zone Project was established to understand the radioactive and chemical contamination in the soil beneath the tanks as the result of leaks and discharges from past plutonium-production operations. The vadose zone is the area of soil between the ground surface and the water table 200-to-300 feet below. The project tracks and monitors contamination in the soil. Technologies are being developed and deployed to detect and monitor contaminants. Interim surface barriers, which are barriers put over the single-shell tanks, prevent rain and snow from soaking into the ground and spreading contamination. The impermeable barrier placed over T Farm, which was the site of the largest tank waste leak in Hanford's history, is 60,000 square feet and sloped to drain moisture outside the tank farm. The barrier over TY Farm is constructed of asphalt and drains moisture to a nearby evaporation basin. Our discussion of technology will address the incredible challenge of removing waste from Hanford's single-shell tanks. Under the terms of the Tri-Party Agreement, ORP is required to remove 99 percent of the tank waste, or until the limits of technology have been reached. All pumpable liquids have been removed from the single-shell tanks, and work now focuses on removing the non-pumpable liquids. Waste retrieval was completed from the first single-shell tank in late 2003. Since then, another six single-shell tanks have been retrieved to regulatory standards. (authors)

  1. Casting Technology Development for SFR Metallic Fuel

    International Nuclear Information System (INIS)

    Fabrication technology of metallic fuel for sodium fast reactor (SFR) is being developed in Korea as a national mid- and long-term nuclear R and D program from 2007. The metallic fuel for SFR should be remotely fabricated under a radiation shielded environment such as a glove box or hot cell, because it contains long-lived minor actinides such as Np, Am and Cm. In order to design a reliable remote fabrication system, various casting techniques have been studied by using U-Zr and U-Zr-RE alloys as surrogate fuel material. Rare earth elements such as Ce or Nd were used as a surrogate for minor actinide elements or solid solution fission products. Macro-scale soundness, microstructures and compositional homogeneity of metallic fuel samples fabricated by vacuum-assisted injection casting, vacuum-assisted gravity casting, centrifugal atomization and continuous casting were compared. Although sound slugs of U-Zr metallic fuel of 4?6 mm in diameter could be fabricated by vacuum-assisted injection casting or vacuum-assisted gravity casting, it was necessary to consider that vaporization of Am and volume of radioactive wastes such as crucibles and molds should be minimized. Effects of casting parameters on the volatile loss, and effects of coatings on the chemical reaction between metallic fuel and molds are discussed. Some methods to reduce the volatile Am loss and waste molds and crucibles will be proposed. Short rods of U-Zr or U-Zr-Ce fuel will be fabricated by the vacuu-Ce fuel will be fabricated by the vacuum-assisted gravity casting technique for an irradiation test in the HANARO research reactor from 2010.

  2. The development of radiotherapy: physics, technology methods.

    Science.gov (United States)

    1996-01-01

    Radiotherapy was introduced in Sweden already before the turn of the century, ie, a few years after the discovery of x-rays and radioactivity. Pioneering contributions were made by Forssell, Berven, Heyman, Sievert, and Strandqvist in general radiotherapy, gynecologic radiotherapy, dosimetry, teleradium methods, and radiation biology. Technological advancements, along with nearly 100% followup of treatment effects, created a foundation for compiling early empirical experience in a methodologically sound specialty. Therapeutic radiology in Sweden was distinguished from diagnostic radiology already in 1917, at which time the specialties of general and gynecologic radiotherapy were founded. These specialties later developed into general and gynecologic oncology. Progress during recent decades has been characterized by access to better equipment such as telegamma devices and accelerators for external radiotherapy, and new radionuclides, eg, for remote controlled local application. With CT (computed tomography) and MRI (magnetic resonance imaging), SPECT and PET (tomography using gamma radiation and positron-irradiated nuclides), and ultrasound diagnostics, the anatomic basis for individual dose planning has radically improved. Dosage can now be planned with high precision and visualized in three dimensions using advanced computer programs. Technical safety has increased with improved methods for in vivo dosimetry and computer-controlled verification of all parameters for every treatment. It is now possible to deliver the intended radiation dose to a benign tumor without causing serious side effects. Important research fields include the impact of different fractionation schedules on the effects of radiation and how radiotherapy can best be combined with other forms of therapy such as surgery and chemotherapy.

    1999-02-01

    Nineteen ninety-eight has been a transition year for Engineering, as we have moved from our traditional focus on thrust areas to a more focused approach with research centers. These five new centers of excellence collectively comprise Engineering's Science and Technology program. This publication summarizes our formative year under this new structure. Let me start by talking about the differences between a thrust area and a research center. The thrust area is more informal, combining an important technology with programmatic priorities. In contrast, a research center is directly linked to an Engineering core technology. It is the purer model, for it is more enduring yet has the scope to be able to adapt quickly to evolving programmatic priorities. To put it another way, the mission of a thrust area was often to grow the programs in conjunction with a technology, whereas the task of a research center is to vigorously grow our core technologies. By cultivating each core technology, we in turn enable long-term growth of new programs.

    The invention of x-ray at the end of the 19th century (November, 1895) indicated that nuclear technology is not a new thing associated with health, as well as the development of nuclear medicine in Indonesia. The first Nuclear Medicine Unit in Indonesia was established soon after the first atomic reactor operated in 1965, and in fact, the use of nuclear technology has given significant contribution in this health sector. The nuclear science and technology activities in health tend to be directed for processing technologies, analysis, instrumentation engineering, and producing of medical support such as radioisotopes and radiopharmaceuticals. In this context, the development of nuclear science and technology in this field is mostly often associated with the demand driven, especially for efficiency, quality and its production and application of diagnosis and therapy. Past and recent development of nuclear technology and its application in health will be described in this paper. Existing facilities and infrastructure and scientific competencies of human resources could still be improved to gain the optimal condition. To strengthen national capacity building, the technologists, stake holders/industries and policy makers should be synchronized in providing the same vision and perception. (author)

    2012-12-01

    Full Text Available Purpose—Social technologies continue to grow in popularity in society. Even though the term “social technology” is most commonly used to refer to new social media such as Twitter and Facebook, a redefinition of this concept based on the original definition is needed. Nowadays the concept of “social technology” has several aspects, which destabilize the dominant image of technology. It emphasizes the social sciences and the humanities as shapers of society, reconsiders the strength of “soft technologies.” The aim of this paper is to provide rich insight into the concept of social technologies’ and to develop the meaning of social technologies in information and knowledge society by analysing new needs and application forms of social technologies.Findings—the research contributed to the understanding of the concept of social technologies. Based on the analysis and synthesis of the scientific literature, a theoretical framework for defining social technologies was developed.Research limitations/implications—the research is limited in a few aspects. For a deeper understanding of social technologies and for developing technological perspectives in social sciences a broader theoretical, as well as empirical, research is necessary. In order to generalise the research findings, further research should include different dimensions from the perspective of other sciences.

  15. Adaptation in the context of technology development and transfer

    2015-01-01

    Starting from a summary of key developments under the United Nations Framework Convention on Climate Change (UNFCCC) related to adaptation and technologies, the commentary provides an initial review of the available literature relevant to adaptation in the context of technology development and transfer. It summarizes what technologies for adaptation are, how they relate to development, and what their role is in adaptation. It subsequently highlights a number of policy and research issues that could be important to inform future policy. The commentary has two key messages. First, it argues that informed policy decisions on technology development and transfer to enhance adaptation require systematic assessments of the findings in the theoretical and empirical literature. Second, in light of the potential for overlap between processes for adaptation and processes for technologies for adaptation, there is a need for coordination and exchange of information between the work under the Cancun Adaptation Framework and under the Technology Mechanism of the UNFCCC.

    Oeftering, Richard C.; Struk, Peter M.; Taleghani, barmac K.

    2011-01-01

    This paper discusses the establishment of a Supportability Technology Development Roadmap as a guide for developing capabilities intended to allow NASA s Constellation program to enable a supportable, sustainable and affordable exploration of the Moon and Mars. Presented is a discussion of supportability, in terms of space facility maintenance, repair and related logistics and a comparison of how lunar outpost supportability differs from the International Space Station. Supportability lessons learned from NASA and Department of Defense experience and their impact on a future lunar outpost is discussed. A supportability concept for future missions to the Moon and Mars that involves a transition from a highly logistics dependent to a logistically independent operation is discussed. Lunar outpost supportability capability needs are summarized and a supportability technology development strategy is established. The resulting Lunar Surface Systems Supportability Strategy defines general criteria that will be used to select technologies that will enable future flight crews to act effectively to respond to problems and exploit opportunities in an environment of extreme resource scarcity and isolation. This strategy also introduces the concept of exploiting flight hardware as a supportability resource. The technology roadmap involves development of three mutually supporting technology categories, Diagnostics Test and Verification, Maintenance and Repair, and Scavenging and Recycling. The technology roadmap establishes two distinct technology types, "Embedded" and "Process" technologies, with different implementation and thus different criteria and development approaches. The supportability technology roadmap addresses the technology readiness level, and estimated development schedule for technology groups that includes down-selection decision gates that correlate with the lunar program milestones. The resulting supportability technology roadmap is intended to develop a set of technologies with widest possible capability and utility with a minimum impact on crew time and training and remain within the time and cost constraints of the Constellation program.

    International Nuclear Information System (INIS)

    With the evolutionary change in the production activities of human societies, the concept of development has also been changing. In the recent years the emphasis has been on the environmentally sound and sustainable development. The environmentally sound and sustainable development can be obtained through judicious use of technology. Technology as a resource transformer has emerged as the most important factor which can constitute to economic growth. But technology is not an independent and autonomous force, it is only an instrument which needs to be used carefully, properly and appropriately which necessitates technology management. (author)

  20. Information and Communication Technology: Gender Issues in Developing Nations

    Directory of Open Access Journals (Sweden)

    Kimberly Betz Leahy

    2003-01-01

    Full Text Available As Developing Nations seek to leverage scarce resources toward the goal of achieving a developed status they must reevaluate past practices and explore available and affordable technologies. Where in-formation and communication infrastructures are weak, use of low-cost, easily distributed technologies have proven effective. Still, many developing nations have failed to incorporate a resource in great abundance, their women, to use these new technologies to greatest advantage. This paper will address the implications of women's lack of economic and educational parity, and offer examples of how the education of women through the use of information and communication technology can enhance a nation's gross domestic product (GDP.

    2014-07-01

    Full Text Available The tipping point, the decisive point in time in the competition between old and new, is an interesting phenomenon in physics of today. This aspect in technology acceptance is connected to many business decisions such as technology investments, product releases, resource allocation, sales forecasts and, ultimately, affects the profitability and even survival of a company. The tipping point itself is based on many stochastic and dynamic variables, and the process may at least partly be described as path-dependent. This paper analyses the tipping point from three aspects: (1 product performance, (2 features of the market and infrastructure (including related technologies and human network externalities, and (3 actions of the incumbents (including customer lock-in, systems lock-in, and sustaining innovation. The paper is based on the Bass s-curve idea and the technology trajectory concept proposed by Dosi. Three illustrative cases are presented to make the point of the multiple factors affecting technology acceptance and, thus, the tipping point. The paper also suggests outlines for further research in field of computer simulation.

  3. Overcoming regulatory barriers: DOE environmental technology development program

    International Nuclear Information System (INIS)

    The potential to improve environmental conditions via compliance or restoration is directly related to the ability to produce and apply innovative technological solutions. However, numerous organizations, including the US General Accounting Office (GAO), the EPA National Advisory Council for Environmental Policy and Technology (NACEPT), the DOE Environmental Management Advisory Board (EMAB), and the National Science and Technology Council (NSTC) have determined that significant regulatory barriers exist that inhibit the development and application of these technologies. They have noted the need for improved efforts in identifying and rectifying these barriers for the purpose of improving the technology development process, providing innovative alternatives, and enhancing the likelihood of technology acceptance by all. These barriers include, among others, regulator and user bias against ''unknown/unproven'' technologies; multi-level/multi-media permit disincentives; potential liability of developers and users for failed implementation; wrongly defined or inadequate data quality objectives: and lack of customer understanding and input. The ultimate goal of technology development is the utilization of technologies. This paper will present information on a number of regulatory barriers hindering DOE's environmental technology development program and describe DOE efforts to address these barriers

    2009-01-01

    Videogame developers have utilized many types of display technology, from oscilloscopes to Teletypes to high-definition LCD displays. Two significant early display technologies, raster scan and random scan CRTs, played a significant part in the history and evolution of videogames. A study of these technologies shows how the choice of one or the other, and the need to port games between the two, influenced game design and prompted developers to innovate.

  6. Accumulation of operational history through emulation test to meet proven technology requirement for newly developed I and C technology

    International Nuclear Information System (INIS)

    As new advanced digital I and C technology with potential benefits of higher functionality and better cost effectiveness is available in the market, NPP (Nuclear Power Plant) operators are inclined to use the new technology for the construction of new plant and the upgrade of existing plants. However, this new technology poses risks to the NPP operators at the same time. These risks are mainly due to the poor reliability of newly developed technology. KHNP's past experiences with the new equipment shows many cases of reliability problems. And their consequences include unintended plant trips, lowered acceptance of the new digital technology by the plant I and C maintenance crew, and increased licensing burden in answering for questions from the nuclear regulatory body. Considering the fact that the risk of these failures in the nuclear plant operation is far greater than those in other industry, nuclear power plant operators want proven technology for I and C systems. This paper presents an approach for the emulation of operational history through which a newly developed technology becomes a proven technology. One of the essential elements of this approach is the feedback scheme of running the new equipment in emulated environment, gathering equipment failure, and correcting the design(and test bed). The emulation of environment includes normal and abnormal events of the new equipment such as reconfiguration of control system due to power failure, plant operation incldue to power failure, plant operation including full spectrum of credible scenarios in an NPP. Emulation of I and C equipment execution mode includes normal operation, initialization and termination, abnormal operation, hardware maintenance and maintenance of algorithm/software. Plant specific simulator is used to create complete profile of plant operational conditions that I and C equipment is to experience in the real plant. Virtual operating crew technology is developed to run the simulator scenarios without involvement of actual operators at the emulated environment. Verification and validation are performed for detecting problems of the new technology. Verification of the equipment is done in two ways, one is to evaluate the features of the equipment according to the criteria derived from good practices of well proven I and C products and the second is to evaluate the features of the equipment by I and C experts. Validations are done in two ways, one is to validate the functions and performance of the equipment and the other is to validate the robustness of the equipment by accumulation operational experience.

  10. The Clean Development Mechanism and neglected environmental technologies

    International Nuclear Information System (INIS)

    The Clean Development Mechanism (CDM) provides an institutional framework for developed countries to support projects that reduce greenhouse gas emissions in developing countries. Are the technologies promoted those most needed by the recipient countries? We address this question by first reviewing Technology Needs Assessments prepared by developing countries, and then comparing the stated needs to the technologies most frequently promoted via CDM. While there appears to be a good match between requested technologies and those used in CDM, desired technologies such as solar energy for remote locations, biofuels, improved cooking stoves, and efficient lighting appear “neglected” by CDM. Nonetheless, a review of costs for these technologies suggests that many could be cost effective for developing countries. For projects requiring wide dispersal of household items, such as cooking stoves or lighting, the administrative burdens of CDM provide a hurdle. In other cases, difficulties quantifying the ancillary benefits of these projects hinder the promotion of these technologies. We conclude with possible explanations for why these technologies are neglected and suggestions for future research. - Highlights: ? We identify technologies desired by developing countries but not provided via CDM. ? Solar PV is neglected due to high costs. ? The CDM process provides a hurdle for improved cooking stoves and efficient lighting. ? Implications for CDM and climate policy are discussed
