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.

Tissue tightening technologies: fact or fiction.  

UK PubMed Central (United Kingdom)

Skin laxity is associated with chronological aging and exposure to solar radiation. The authors summarize the advantages and limitations of current laser, light-, and radiofrequency (RF)-based technologies purported to treat skin laxity by effecting heat-induced collagen contraction and subsequent remodeling during the months after treatment. Although penetration of laser or broadband light to the deep dermal layers is limited because of scattering of the light by epidermal melanin, a new device in which broadband infrared light is minimally scattered may overcome these limitations. RF energy offers a treatment alternative that has not only been proven to promote collagen contraction and remodeling but also is not scattered by epidermal constituents. Recently launched devices that use combinations of optical and RF energy achieve clinical benefits at lower and therefore safer levels of energy, with only mild pain and few adverse effects. A combined infrared-RF device takes maximum advantage of both optical and RF technologies to achieve the desired clinical effect. The electrooptical synergy systems have proven to be safe, effective, reliable, and user-friendly. Other more advanced powerful technologies may also be effective in this setting.

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 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)

Wind turbines - facts from 20 years of technological progress  

Energy Technology Data Exchange (ETDEWEB)

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)

Wind park technology with FACTS and STATCOM performance  

Energy Technology Data Exchange (ETDEWEB)

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)

NREL Collaborates to Improve Wind Turbine Technology (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

NREL's Gearbox Reliability Collaborative leads to wind turbine gearbox reliability, lowering the cost of energy. Unintended gearbox failures have a significant impact on the cost of wind farm operations. In 2007, the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC), which follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers, and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. NREL and other GRC partners have been able to identify shortcomings in the design, testing, and operation of wind turbines that contribute to reduced gearbox reliability. In contrast to private investigations of these problems, GRC findings are quickly shared among GRC participants, including many wind turbine manufacturers and equipment suppliers. Ultimately, the findings are made public for use throughout the wind industry. This knowledge will result in increased gearbox reliability and an overall reduction in the cost of wind energy. Project essentials include the development of two redesigned and heavily instrumented representative gearbox designs. Field and dynamometer tests are conducted on the gearboxes to build an understanding of how selected loads and events translate into bearing and gear response. The GRC evaluates and validates current wind turbine, gearbox, gear and bearing analytical tools/models, develops new tools/models, and recommends improvements to design and certification standards, as required. In addition, the GRC is investigating condition monitoring methods to improve turbine reliability.

WEO-2006 Fact Sheet: Energy for Cooking in Developing Countries  

Energy Technology Data Exchange (ETDEWEB)

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.

Field Assembled Cable Termination (FACT): development and qualification  

Energy Technology Data Exchange (ETDEWEB)

As offshore developments are pushed into deeper waters, new enabling technologies are required to terminate electrical, optical and hybrid cables. Past experience has shown that, depending upon the combination of cable construction and termination design, two failure modes are possible. Firstly, in many cable terminations, the individual cores of the cables pass from an atmospheric cable breakout chamber into a dielectric fluid-filled pressure-balanced splice chamber. The resulting loads placed upon the core cross-sections, due to the pressure gradient between the two modules, initiates the buckling of the cores into the atmospheric breakout chamber. Secondly, many cable terminations have a single-sealing or cable element separating the dielectric fluid-filled volume from the cable and conductor interstices which are, in many cases, atmospheric. If either of the sealing or cable elements is compromised, the dielectric fluid may vent from the termination. A new cable termination technology has been developed to extend the operational depth and significantly increase the reliability of cable terminations. This modularized system completely isolates the cable elements from the pressure-balanced splice chamber and ambient environment. This paper will review the two failure modes and provide a summary of the qualification tests performed to verify the suitability of this new technology. (author)

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

DEFF Research Database (Denmark)

Merges and Nelson have proposed that pioneer patents have enabled their owners to 'block' or 'hold-up' downstream innovation in cases as important as the car, radio, aircraft and electric lighting (Merges and Nelson 1990, ; Merges and Nelson 1994). Merges and Nelson use their work to question the value of Kitch's prospect theory of patents, a theory that the social value of patents is that they enable the efficient coordination of technological development.    I re-examine history and legal sources bearing on Merges and Nelson's illustrative cases and find no case to illustrate downstream innovation suppression as claimed.  I argue instead that these cases illustrate problems in the coordination of development caused by various faults in the administration of patents by US Congress, the US Patent Office or the courts.

Energy, technology, development  

Energy Technology Data Exchange (ETDEWEB)

Energy and technology are essential ingredients of development, it is only through their use that it became possible to sustain a population of almost 5 billion on Earth. The challenges to eradicate poverty and underdevelopment in developing countries in the face of strong population increases can only be successfully met with the use of advanced technology, leapfrogging the path followed in the past by today's industrialized countries. It is shown in the paper that energy consumption can be decoupled from economic development. Such possibility will contribute significantly in achieving sustainable development. 10 refs., 4 figs., 3 tabs.

Stirling technology development status  

Energy Technology Data Exchange (ETDEWEB)

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.

Transmutation Technology Development  

International Nuclear Information System (INIS)

[en] 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

The Development of Reasoning about Beliefs: Fact, Preference, and Ideology.  

UK PubMed Central (United Kingdom)

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 reasoning about ideological beliefs is the result of prolonged experience with the physical and social world, children and adults should reveal distinct patterns of differentiating kinds of beliefs, and this difference should be particularly pronounced with respect to ideological beliefs. On the other hand, if adults' reasoning about beliefs is a basic component of social cognition, children and adults should demonstrate similar belief representations and patterns of belief differentiation. Two experiments demonstrate that 5-10 year old children and adults similarly judged religious beliefs to be intermediate between factual beliefs (where two disagreeing people cannot both be right) and preferences (where they can). From the age of 5 years and continuing into adulthood, individuals distinguished ideological beliefs from other types of mental states and demonstrated limited tolerance for belief-based disagreements.

Development of sodium technology  

Energy Technology Data Exchange (ETDEWEB)

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.

Asian and African Development Trajectories Revisiting Facts and Figures  

Directory of Open Access Journals (Sweden)

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.

Current Status on Mechanical Disassembly and Shearing System Development in FaCT Project  

International Nuclear Information System (INIS)

Japan Atomic Energy Agency (JAEA) has been carried out the Fast Reactor Cycle Technology Development (FaCT) project in cooperation with the Japanese electric utilities. As for the development of the advanced aqueous reprocessing in the FaCT project, JAEA and Japan Atomic Power Company (JAPC) have been developing a reliable disassembly and shearing system for FBR fuel reprocessing. As configuration of FBR fuel assembly, fuel pins are covered with a hexagonal shaped wrapper tube, which must be separated from the fuel pins prior to the shear process. We proposed new disassembly procedures combined two mechanical cutting operations and one pulling operation. The cutting operation has two modes, such as the slit-cutting mode for the wrapper tube cutting and the crop-cutting mode for the pin bundle cutting to separate the entrance nozzle. After the slit-cut operations, the wrapper tube will be pulled and removed from the fuel pins bundle. Some fundamental experiments were carried out to select the cutting tool by using FMS and ODS steals nominated as the material of the commercial FBR fuel, and CBN wheel shown the highest durability and selected as the promising tool. With reflecting of these technologies, an engineering-scale system testing device was designed and fabricated. And to confirm the system performance, some demonstration tests by using a simulated fuel assembly of prototype reactor 'Monju' has been stared. In the fuel shearing process, we proposed the short-length shearing to obtain highly fragmented fuel to provide efficient fuel dissolution, which required adapting to the uranium crystallization process. The fragment rate is affected by the shear-length and the layout of fuel pins in the shear magazine. In order to optimize the shear conditions, parametric tests by using shear machine and simulated fuel pins was carried out. As the results, optimum shear length is selected to be 10 mm. In this paper, we will report the latest experimental results for these systems. This work was supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT).

Developing human technology curriculum  

Directory of Open Access Journals (Sweden)

Full Text Available During the past ten years expertise in human-computer interaction has shifted from humans interacting with desktop computers to individual human beings or groups of human beings interacting with embedded or mobile technology. Thus, humans are not only interacting with computers but with technology. Obviously, this shift should be reflected in how we educate human-technology interaction (HTI) experts today and in the future. We tackle this educational challenge first by analysing current Master’s-level education in collaboration with two universities and second, discussing postgraduate education in the international context. As a result, we identified core studies that should be included in the HTI curriculum. Furthermore, we discuss some practical challenges and new directions for international HTI education.

Robotics Technology Development Program. Technology summary  

Energy Technology Data Exchange (ETDEWEB)

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 & Dismantlement (D&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&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&D and CC&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.

Information technology in developing countries  

Energy Technology Data Exchange (ETDEWEB)

Broadly defined, any technology has three aspects: hardware, software and orgware - the last, orgware, standing for the organization of man and machines to take advantage of the hardward and software in the provision of certain valuable functions of the technology. This concept is particularly important for information technologies. The national strategy for a developing country vis-a-vis information technologies may be considered from two perspectives: acquisition from foreign countries and development by indigenous institutions. Given the many demands on its resources and the shortage of technical specialists, a developing country would probably be better off not to enter into hardware development in the foreseeable future in the field of information technologies. On the other hand, some of the most advanced hardware may be acquired from foreign countries even if this hardware is not being utilized by the industrialized countries themselves. From the perspective of indigenous development of information technologies, using domestic capabilities and institutions, it appears that a developing country should focus on software and orgware development. To be successful, these developments must take into account the domestic, social, cultural and institutional heritages - something which cannot really be accomplished by foreign scientists and engineers. 8 references, 1 table.

Lost circulation technology development projects  

Energy Technology Data Exchange (ETDEWEB)

Lost circulation is the phenomenon where circulating drilling fluid is lost to fractures or pores in the rock formation rather than returning to the surface through the wellbore annulus. In geothermal drilling, lost circulation can be a serious problem that contributes greatly to the cost of the average geothermal well. A DOE-sponsored program is underway at Sandia National Laboratories to develop new technology for solving lost circulation problems. The Lost Circulation Technology Development Program currently consists of twelve projects in three areas: technology to plug porous and minor-fracture loss zones; technology to plug major-fracture loss zones; and technology to characterize loss zones. This paper describes the program and highlights recent progress. 12 refs., 10 figs.

Multichip module technology development  

International Nuclear Information System (INIS)

[en] 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

Building State-of-the-Art Wind Technology Testing Facilities (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

The new Wind Technology Test Center is the only facility in the nation capable of testing wind turbine blades up to 90 meters in length. A critical factor to wind turbine design and development is the ability to test new designs, components, and materials. In addition, wind turbine blade manufacturers are required to test their blades as part of the turbine certification process. The National Renewable Energy Laboratory (NREL) partnered with the U.S. Department of Energy (DOE) Wind Program and the Massachusetts Clean Energy Center (MassCEC) to design, construct, and operate the Wind Technology Center (WTTC) in Boston, Massachusetts. The WTTC offers a full suite of certification tests for turbine blades up to 90 meters in length. NREL worked closely with MTS Systems Corporation to develop the novel large-scale test systems needed to conduct the static and fatigue tests required for certification. Static tests pull wind turbine blades horizontally and vertically to measure blade deflection and strains. Fatigue tests cycle the blades millions of times to simulate what a blade goes through in its lifetime on a wind turbine. For static testing, the WTTC is equipped with servo-hydraulic winches and cylinders that are connected to the blade through cables to apply up to an 84-mega Newton meter maximum static bending moment. For fatigue testing, MTS developed a commercial version of NREL's patented resonant excitation system with hydraulic cylinders that actuate linear moving masses on the blade at one or more locations. This system applies up to a 21-meter tip-to-tip fatigue test tip displacement to generate 20-plus years of cyclic field loads in a matter of months. NREL also developed and supplied the WTTC with an advanced data acquisition system capable of measuring and recording hundreds of data channels at very fast sampling rates while communicating with test control systems.

Lost circulation technology development status  

Energy Technology Data Exchange (ETDEWEB)

Lost circulation is the loss of drilling fluid from the wellbore to fractures or pores in the rock formation. In geothermal drilling, lost circulation is often a serious problem that contributes greatly to the cost of the average geothermal well. The Lost Circulation Technology Development Program is sponsored at Sandia National Laboratories by the US Department of Energy. The goal of the program is to reduce lost circulation costs by 30--50% through the development of mitigation and characterization technology. This paper describes the technical progress made in this program during the period April 1991--March 1992. 8 refs.

The development of a Functional Assessment of Cancer Therapy (FACT) questionnaire to assess dermatologic symptoms associated with epidermal growth factor receptor inhibitors (FACT-EGFRI-18).  

UK PubMed Central (United Kingdom)

PURPOSE: Dermatologic toxicities from epidermal growth factor receptor inhibitors (EGFRIs) are common, disrupt health-related quality of life (HRQL), and lead to dose reduction or discontinuation of potentially life-saving cancer therapy. The Functional Assessment of Cancer Therapy (FACT)-EGFRI was developed to measure HRQL among patients receiving EGFRIs. METHODS: The FACT-EGFRI was developed through the triangulation approach using the established functional assessment of chronic illness therapy method of patient questionnaire construction. This included literature review, qualitative data collection and analysis, and quantitative survey data collection on candidate items to identify the most important items related to EGFRI-induced dermatologic toxicities according to patients receiving EGFRIs and expert clinicians. RESULTS: Twelve expert clinicians and 20 patients were interviewed for the initial questionnaire development. Dermatologic symptoms associated with epidermal growth factor receptor inhibitors endorsed as high priority by both patients and oncologist experts were selected. The final version includes 18 items which assess the physical, emotional, social, and functional impact that skin, nail, and hair toxicities have on patients' HRQL. CONCLUSIONS: The FACT-EGFRI-18 measures the severity of patient-reported EGFRI-induced dermatologic toxicities and effects on HRQL and was developed using qualitative data from patients and expert clinicians. Further validation is underway. The FACT-EGFRI-18 may be useful for clinicians and researchers to quantify dermatologic toxicities from the patient perspective in standard clinical care, evaluate the effectiveness of interventions to prevent or reduce dermatologic toxicities, and to guide treatment decision making.

Night vision device technology development  

Energy Technology Data Exchange (ETDEWEB)

This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). This project sought to develop microchannel plate (MCP) technologies for enhancement of night vision device (NVD) capabilities. First, segmented microchannel plates with independent gain control to minimize loss of low level light images in the presence of a bright light source (e.g., battlefield lasers, flares, and headlights) need to be developed. This enables, for example, enhanced vision capabilities during night operations in, for example, a city environment and continuous capability of aviators to see the horizon, nearground obstructions, and ground targets. Furthermore, curved microchannel plate technology to increase the field of view of NVDs while minimizing optical aberrations needs to be developed and applied. This development would significantly enhance peripheral vision capabilities of aviators and result in easier adaptation of the human eye to NVDs.

The development of nutritional-supplement fact sheets for Irish athletes: a case study.  

UK PubMed Central (United Kingdom)

The use of sport supplements presents a dilemma for many of those involved in supporting athletes, including coaches, families, support staff, and the athletes themselves. Often the information that they source can be incorrect and promote a biased view regarding the use of nutritional supplements. The aim of this case study was to describe the process that occurred around the development of a series of targeted educational fact sheets on a range of nutritional supplements for Irish athletes. It describes the initiation and support of the process by the Irish Sports Council; one of its subgroups, the Food and Food Supplements Committee; and the Irish Institute of Sport. A needs assessment through questionnaires was carried out to establish the most commonly used sport nutrition supplements by athletes age 16 or over in Ireland. Respondents completed 105 questionnaires over a 4-mo period in 2008-09 that led to the production of 20 supplement fact sheets. These supplement fact sheets will enable Irish athletes to access high-quality, up-to-date, scientific information about the supplements they have reported consuming. Since personal reading had a strong influence over athletes' decision-making process for taking nutritional supplements, as did scientific research, fact sheets available on the Internet from a reliable source are an ideal way to educate Irish athletes.

Performance specifications for technology development  

International Nuclear Information System (INIS)

The objective of any instrument, technique, or method development project is to deliver needed and usable technologies to customers. To help the US Department of Energy's Office of Environmental Management and its investigators meet that goal, technology performance specifications are being developed for implementation in research and development and in documentation, testing, and evaluation projects. Technology performance specifications will be used to establish milestones, evaluate the status of ongoing projects, and determine the success of completed projects. Preliminary performance specifications will be required in proposals and will be highly weighted in the technical evaluation. The general performance specification approach is to document what currently exists or is nearing completion and compare that baseline to the customers' needs to identify the unmet requirements. These unmet requirements then form the basis for the technology development needs that OTD investigators must address. The process needs to be quantitative, where appropriate, to focus project goals away from vague generalities like ''better'' toward specifics ''reduce detection limit from 50 ?g/L to 100 ng/L'', or from ''cheaper'' to ''reduction of labor costs for step A from 4 hours to 0.5 hour.''

Technology Transfer and the Product Development Process  

Energy Technology Data Exchange (ETDEWEB)

It is my pleasure this morning to address a topic that is much talked about in passing but rarely examined from a first person point of view. That topic is Technology Transfer. Over the next 30 minutes I'd like to approach Technology Transfer within the context of the Product Development Process looking at it from the perspectives of the federal government researcher and the industry manufacturer/user. Fist let us recognize that we are living in an ''Information Age'', where global economic and military competition is determined as much by technology as it is by natural resource assets. It is estimated that technical/scientific information is presently growing at a rate of l3 percent per year; this is expected to increase to 30 percent per year by the turn of the century. In fact, something like 90 percent of all scientific knowledge has been generated in the last 30 years; this pool will double again in the next 10-15 years (Exhibit 1). Of all the scientists and engineers throughout history, 90% live and work in the present time. Successfully managing this technical information/knowledge--i.e., transforming the results of R&D to practical applications--will be an important measure of national strength. A little over a dozen years ago, the United States with only 5 percent of the world's population was generating approximately 75 percent of the world's technology. The US. share is now 50 percent and may decline to 30 percent by the turn of the century. This decline won't be because of downturn in U.S. technological advances but because the other 95 percent of the world's population will be increasing its contribution. Economic and military strength then, will be determined by how quickly and successfully companies, industries, and nations can apply new technological information to practical applications--i.e., how they manage technology transfer within the context of the product development process. Much discussion and pronouncements are ongoing in public forums today over the apparent decline in global competitiveness of U.S. industry. The question is why does U.S. industry not succeed in the development and marketing of competitive products when they lead in the generation of new technology.

Genetic technology and agricultural development.  

UK PubMed Central (United Kingdom)

The genetic technologies being adopted in South Asia are significant factors in the agricultural development of the area. But, labeling them " miracle seeds," solely responsible for recent agricultural growth, is misleading. Certainly the introduction of new genetic technology has catalyzed South Asian agriculture and has instilled a new dynamism essential to economic development. Somewhat similar phenomena have, however, been observed in other parts of the world in other periods of history. The nature of these genetic technologies, how they are being applied, and their limits and potential have been explored above. Also, the effects of these varieties on the generation of employment, and the distribution of benefits accruing from them have been examined in preliminary fashion. Stemming from the preceding discussion, two areas of priority appear obvious. First, the close association of genetic technologies with irrigation suggests that irrigation should receive more attention than it has in the past. Large-scale public irrigation schemes are expensive and have tended to yield low rates of return. However, there appears to be room for marginal increases in, or improvements of, existing irrigation facilities. Second, even with a rapid spread of the practices associated with highyeild varieties, it may be too much to expect the farm sector to absorb the expected increases in the rural labor force. The generation of employment is a major problem in India as well as in most other developing countries. Hence, possibilities for expanding rural, nonfarm employment and controlling population growth should be sought vigorously.

Night vision device technology development  

Energy Technology Data Exchange (ETDEWEB)

This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). This project sought to develop microchannel plate (MCP) technologies for enhancement of night vision device (NVD) capabilities. First, the authors addressed the need for segmented microchannel plates with independent gain control to minimize loss of low level light images in the presence of a bright light source (e.g., battlefield lasers, flares, and headlights). This would enable, for example, enhanced vision capabilities during night operations in a city environment and continuous capability of aviators to see the horizon, near-ground obstructions, and ground targets. Second, the authors addressed the need for curved microchannel plate technology to increase the field of view of NVDs while minimizing optical aberrations. This development would significantly enhance peripheral vision capabilities of aviators and result in easier adaptation of the human eye to NVDs. The authors have developed two technologies to overcome these problems, and they have initiated a collaborative effort with an industrial partner to develop a proof-of-principle prototype.

competitive technologies for sustainable development  

International Nuclear Information System (INIS)

[en] 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 trans

Development of safety analysis technology  

Energy Technology Data Exchange (ETDEWEB)

The present research aims at development of the necessary technology for safety analysis adequate for Korean nuclear power plants. The safety analysis technology enables to reduce the expenditure both by eliminating excessive conservatism incorporated in nuclear reactor design and by increasing safety margins in the operation. It also contributes to improving plant safety through realistic analysis of the emergency operating procedures (EOP). During this year the current status of LOCA analysis codes which are widely used in the world, is reviewed in order to propose an adequate methodology in the area of LOCA analysis. An assessment of the codes, RELAP5/MOD3 and CATHARE2, on `BETHSY 6 cold leg break` also has been performed, including comparison of codes per se. The result of the status review shows that the current status of technology on LOCA analysis in Korea, does not stand the same level as that of advanced countries; however, its settlement seems to be promising when continued efforts be devoted to analyzing integral experiments like BETHSY with the codes used this year. Overall physical phenomena observed in the BETHSY experiment, are predicted preferably by two codes; however, the interfacial model adapted in RELAP5/MOD3 is considered to need further investigation. The developed technology would be applied to the improvements of plant economy, safety systems and EOP for accident management in both the existing plants and next-generation plants. In this regard, safety analysis technology plays an important role for the reactor safety, and so the methodology should be continuously developed throughout a long range program.

Ceramic gas turbine technology development  

Energy Technology Data Exchange (ETDEWEB)

AlliedSignal Engines is addressing critical concerns slowing the commercialization of structural ceramics in gas turbine engines. These issues include ceramic component reliability, commitment of ceramic suppliers to support production needs, and refinement of ceramic design technologies. The stated goals of the current program are to develop and demonstrate structural ceramic technology that has the potential for extended operation in a gas turbine environment by incorporation in an auxiliary power unit (APU) to support automotive gas turbine development. AlliedSignal Engines changed the ATTAP ceramic engine test bed from the AGT101 automotive engine to the 331-200[CT] APU. The 331-200[CT] first-stage turbine nozzle segments and blades were redesigned using ceramic materials, employing design methods developed during the earlier DOE/NASA-funded Advanced Gas Turbine (AGT) and the ATTAP programs. The ceramic design technologies under development in the present program include design methods for improved resistance to impact and contact damage, assessment of the effects of oxidation and corrosion on ceramic component life, and assessment of the effectiveness of nondestructive evaluation (NDE) and proof testing methods to reliably identify ceramic parts having critical flaws. AlliedSignal made progress in these activities during 1993 ATTAP efforts. Ceramic parts for the 331-200[CT] engine have been fabricated and evaluated in component tests, to verify the design characteristics and assure structural integrity prior to full-up engine testing. Engine testing is current under way.

Advanced Modular Inverter Technology Development  

Energy Technology Data Exchange (ETDEWEB)

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

The Development of Nutritional Supplement Fact Sheets for Irish Athletes: A Case Study.  

UK PubMed Central (United Kingdom)

The use of sports supplements presents a dilemma for many of those involved in supporting athletes, including coaches, families, support staff and the athletes themselves. Often the information that they source can be incorrect and promote a bias view regarding the use of nutritional supplements. The aim of this case study was to describe the process that occurred around the development of a series of targeted educational factsheets on a range of nutritional supplements for Irish athletes. It describes the initiation and support of the process by the Irish Sports Council, one of its subgroups, The Food and Food Supplements Committee, and the Irish Institute of Sport. A needs assessment through questionnaires was carried out to establish the most commonly used sports nutrition supplements by athletes, aged sixteen or over in Ireland. One hundred and five questionnaires were completed over a 4-month period in 2008-2009 that lead to the production of 20 supplement fact sheets. These supplement fact sheets will enable Irish athletes to access high quality, up to date, scientific information regarding the supplements they have reported consuming. Since personal reading had a strong influence over the athlete's decision-making process for taking nutritional supplements, as did scientific research, fact sheets available on the internet from a reliable source is an ideal way to educate Irish athletes.

FaCT phase-I evaluation on the advanced aqueous reprocessing process (2). Development of mechanical disassembly and short stroke shearing systems for FBR fuel reprocessing  

International Nuclear Information System (INIS)

JAEA promotes a development of an advanced head-end process in FaCT project. We selected mechanical cutting method for disassembly process and short stroke method for shearing process. In the FaCT phase-I, the criteria was set for decision about the innovative technology and some fundamental performances of the innovative technology such as precision, speed, durability, operation performance and system concept were discussed by the engineering test and design work. We designed and fabricated an engineering-scale test device for mechanical disassembly and short stroke shearing and have carried out the engineering tests using simulated fuel assemblies. As a part of the engineering test results, the effects of cutting conditions on the durability of cutting tool and cutting stability were discussed. Also, the reduction of magazine width is effective to improve the precision of sheared pin length, and the bundle of simulated fuel pins were successfully sheared to 10 ± 5mm, which is a target for the sheared pin length. The criteria for the mechanical disassembly technology and the short stroke shearing technology were satisfied, so we judged that the development of innovative technologies has worth going on for the next phase in the FaCT project.

Development of RI Target Production Technology  

International Nuclear Information System (INIS)

This project was accomplished with an aim of productive technical development on the 'enriched target' which is used essentially in radioisotope production. The research was advanced systematically with target production pilot system configuration and core technical development. We composed Yb-176 productive pilot system which equip the chemical purification technique of medical treatment level and proved its capability. Possibilities to separate Zn-67 by the method of using the polarizing light in principle and to separate Zn-70 by the method of using the double optical pumping in theory were also proved. RI target production technologies are recognized excessively with monopolistic techniques of part atomic energy advanced nations such as Russia and US and they are come, but we prepared the opportunity will be able to complete a full cycle of like (RI material production -> RI target production -> RI application) with this project accomplishment. When considering only the direct demand of stable isotope which is used in various industrial, we forecast with the fact that RI target markets will become larger with the approximately 5 billion dollars in 2020 and this technology will contribute in the domestic rising industry creation with high value added

Troll development - the technological challenge  

Energy Technology Data Exchange (ETDEWEB)

Due to the unique combination of difficult circumstances, such as the 340 m water depth, shallow reservoir and great area extent, the development of the Troll hydrocarbon reserves will demand use of new technology on an unprecedented scale. The risks associated with such a bold step are nevertheless clearly recognized, and this paper discusses how the development approach proposed for the Troll field represents a matching of available or minimum- extrapolation technology to the reservoir drainage requirements. A conscious effort has been made to use new technology only in those areas where current techniques, or their extensions, can be shown to be inadequate, and where innovation can be recognized as offering significant cost, safety, technical or operability advantages. A very wide range of solutions has been identified for each of the main technical challenge areas, and a logical and consistent approach has been taken to their evaluation and shortlisting, with particular reference to the inter-relationships and interactions between the individual elements of the total production system. 7 references.

Technology transfer and development: a preliminary look at Chinese technology in Guyana  

Energy Technology Data Exchange (ETDEWEB)

Technology is regarded as a vital ingredient for development. Since developing countries can hardly fill their technological requirements indigenously, such countries tend to acquire the bulk of technology applied to their production systems from abroad. However, the transfer of technology tends to be associated with a series of problems: foreign exchange, inappropriateness, the generation of limited inter-sectorial linkages, limited use of raw materials, and other inputs associated with technology dependency. The study points to the fact that technology transfer need not necessarily be associated with the disadvantages identified in the literature. The study which essentially looks at the use of Chinese technology in clay-brick manufacturing in Guyana, shows that the country was able to reap several development benefits from the technology-transfer arrangement. At the same time, certain problems arising from the technology-transfer package such as the transfer of critical skills in key areas of production, and maintenance and servicing, are discussed. But these, the author argues, are not a function of restrictive conditions found in technology-transfer clauses, but rather of improper technology-transfer management. 2 tables.

Development of nuclear analytical technology  

Energy Technology Data Exchange (ETDEWEB)

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 {approx} 20 {mu}m) and standardization, the examination of variation in fission track characteristic according to nuclear particle size and enrichment({sup 235}U: 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, {alpha}) 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 {sup 252}Cf 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.

JEDI: Jobs and Economic Development Impacts Model, National Renewable Energy Laboratory (NREL) (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

The Jobs and Economic Development Impact (JEDI) models are user-friendly tools that estimate the economic impacts of constructing and operating power generation and biofuel plants at the local (usually state) level. First developed by NREL's Wind Powering America program to model wind energy jobs and impacts, JEDI has been expanded to biofuels, concentrating solar power, coal, and natural gas power plants. Based on project-specific and default inputs (derived from industry norms), JEDI estimates the number of jobs and economic impacts to a local area (usually a state) that could reasonably be supported by a power generation project. For example, JEDI estimates the number of in-state construction jobs from a new wind farm. This fact sheet provides an overview of the JEDI model as it pertains to wind energy projects.

Development of DUPIC safeguards technology  

International Nuclear Information System (INIS)

DUPIC safeguards R and D in the second phase has focused on the development of nuclear material measurement system and its operation and verification, the development of nuclear material control and accounting system, and the development of remote and unmanned containment/surveillance system. Of them, the nuclear material measurement system was authenticated from IAEA and officially used for IAEA and domestic safeguards activities in DFDF. It was also verified that the system could be used for quality control of DUPIC process. It is recognised that the diagnostic software using neural network and remote and unmanned containment/surveillance system developed here could be key technologies to go into remote and near-real time monitoring system. The result of this project will eventually contribute to similar nuclear fuel cycles like MOX and pyroprocessing facility as well as the effective implementation of DUPIC safeguards. In addition, it will be helpful to enhance international confidence build-up in the peaceful use of spent fuel material.

Steam generator decontamination technology development  

International Nuclear Information System (INIS)

The present project is aimed at developing decontamination technology for the steam generator channel head which is urgently required in Kori unit 1 nuclear power plant. The effects of reagent concentration on the dissolution of oxides were investigated in a mini glass loop. An inhibitor and a catalyst were added to the solution. To examine the effects of chemical decontamination on material integrity, general corrosion, crevice corrosion, IGA, SCC tests were carried out. Reductive dissolution rate of oxide increase with the hydronium ion, but is independent of EDTA concentration. Oxidative dissolution rate of Cr-rich oxide in alkaline solution is proportional to KMnO4 concentration and the square root of time in this experimental range, which suggests that oxidative dissolution behavior is in good agreement with unreacted shrinking core model with ash diffusion controlling. Material deterioration due to general corrosion, crevice corrosion, IGC and SCC during decontamination was well within the allowable limits. The S/G channel head, on one fourtieth scale of the Kori unit 1 and the decontamination equipment were designed and fabricated to demonstrate the decontamination process effectiveness and safety. The results of the present project indicate strong possibility that decontamination in the S/G channel head can be carried out in the near future with domestic technology. (Author)

The FY1980 technical accomplishments from the Lawrence Livermore National laboratory (LLNL) for the Fiber Composite Materials Technology Development Task fo the MEST project are summarized. The task is divided into three areas: Engineering data base for flywheel design (Washington University will report this part separately), new materials evaluation, and time-dependent behavior of Kevlar composite strands. An epoxy matrix was formulated which can be used in composites for 120/sup 0/C service with good processing and mechanical properties. Preliminary results on the time-dependent properties of the Kevlar 49/epoxy strands indicate: Fatigue loading, as compared to sustained loading, drastically reduces the lifetime of a Kevlar composie; the more the number of on-off load cycles, the less the lifetime; and dynamic fatigue of the Kevlar composite can not be predicted by current damage theories such as Miner's Rule.

Lost circulation is a problem common in both the geothermal and the solution mining industries. In both cases, drilling is on a relatively large scale (geothermal holes can be as large as 26 inches). Lost circulation technology development for geothermal drilling has been in progress at Sandia National Laboratories for more than 15 years. The initial work centered on lost circulation materials, but testing and modeling indicated that if the aperture of a loss zone is very large (larger than the drill bit nozzles) it cannot be plugged by simply adding materials to the drilling fluid. Thus, the lost circulation work evolved to include: (1) Development of metering techniques that accurately measure and characterize drilling fluid inflow and outflow for rapid diagnosis of los circulation and/or fluid balance while drilling. (2) Construction of a laboratory facility for testing drillable straddle packers (to improve the plugging efficiency of cementing operations) and the actual testing of components of the straddle packer. (3) Construction of a laboratory facility for the testing of candidate porous fabrics as a part of a program to develop a porous packer that places polyurethane foam into a loss zone. (4) Implementing (with Halliburton and CalEnergy Company), a program to test cementitious lost circulation material as an alternative to Portland cement.

Arctic Energy Technology Development Laboratory  

Energy Technology Data Exchange (ETDEWEB)

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.

Policy issues inherent in advanced technology development  

International Nuclear Information System (INIS)

[en] 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

Facts are the enemy of truth-reflections on serendipitous discovery and unforeseen developments in asymmetric catalysis.  

UK PubMed Central (United Kingdom)

As Louis Pasteur said, "Chance favors only a prepared mind." Serendipitous events reorienting the pathway of science often occur through the actions of dedicated individuals with unique cultural and educational backgrounds, an original sense of values, and firm principles. Science is the fountainhead of human knowledge and possesses an indispensable cultural value. Science-based technologies and the innovations derived from them are the foundation of the civilized society in which we live today. All scientific endeavors begin with observations, or facts. However, the real goal of research activity is to convert accumulated knowledge to something with new technological, economic, or social value. Innovation is an essential aspect to assure the continued survival of humanity. And often, as my half-century of research reflects, the act of turning facts into values is facilitated by dialogue. Thus, to acquire the necessary combined wisdom, scientists must have ongoing conversations with the societies they serve, as well as with their counterparts in other nations.

Current Status on Research and Development of Uranium Crystallization System in Advanced Aqueous Reprocessing of FaCT Project  

Energy Technology Data Exchange (ETDEWEB)

As a part of Fast Reactor Cycle Technology Development (FaCT) project, Japan Atomic Energy Agency (JAEA) has been developing a uranium (U) crystallization process for FBR fuel reprocessing in collaboration with Mitsubishi Materials Corporation. This process is based on the difference between solubilities of U and other elements under controlled temperature and acidity. The most part of U in dissolver solution is to be recovered as uranyl nitrate hexahydrate (UNH) crystal by lowering the temperature of the solution. Fundamental process experiment results show that U crystallization is applicable to FBR fuel reprocessing as a U pre-recovery process. Although Cs was precipitated and accompanied with U crystals in some cases, methods to avoid the formation of Cs precipitation or to remove the precipitation are not investigated yet. An annular type continuous crystallizer was selected as the most promising equipment, and continuous operation tests were carried out by an engineering scale crystallizer. During the tests, UNH crystals and mother solution were smoothly discharged from their respective outlet. In this report, the current status on research and development of uranium crystallization process and equipments will be described. Beaker-scale experiments with dissolver solution of irradiated FR fuel were successfully carried out at the Chemical Processing Facility (CPF) of JAEA. The behavior of FPs in U crystallization process will be discussed. On crystallizer development, solid accumulation, blockade of mother solution outlet and blockade of crystal outlet are serious phenomena of non-steady state. For investigation of the operational condition, mal-operation tests were carried out by the engineering scale crystallizer. As a result, non-steady state phenomena can be detected by torque of the screw and other instruments. The instrumentation and control system are also important issues to maintain the stable condition. (authors)

Technology development for radiation shielding analysis  

International Nuclear Information System (INIS)

[en] 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.

Directory of Open Access Journals (Sweden)

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; 2)the 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.

Incentives for Technological Development. BAT Is BAD  

Energy Technology Data Exchange (ETDEWEB)

This paper examines the effect of environmental regulation on a firms incentives to invest in developing cheaper (clean-up) technologies in a model where consumers are willing to pay for environmentally clean technologies. It focuses on two types of policies: a BAT based policy and a commitment policy. In the former policy, the standard is based on the best available technology (BAT) where the regulator re-optimizes environmental regulation in response to new technologies. However, under a commitment policy, the regulator announces a regulation and sticks to it irrespective of the firms adopted technology. The paper finds that cleaner technologies are not adopted if the regulator announces a BAT based policy. A commitment policy not only leads to positive investment in research and development but is also welfare improving.

Technology developments at the burner tip  

Energy Technology Data Exchange (ETDEWEB)

Opportunities that exist for improving energy efficiency and to reduce greenhouse gases in the energy sector were discussed. For end-use natural gas applications, research is being conducted to develop and implement technologies that will reduce CO{sub 2} and other pollutant emissions. These technologies include high efficiency gas substitution of electric technologies, low NO{sub x} burners, and improved combustion control. The Canadian Gas Research Institute (CGRI) has shown that process efficiency can be improved through the use of new burner technology and the substitution of gas for electricity in a gas-fired scrap metal preheater in an electric induction furnace melting scrap steel. Another way to modify the combustion process is to convert a burner from the conventional blue-flame to gas infra-red or catalytic infra-red burner technology. Emissions reductions, improved throughput and improved product quality are additional benefits seen from the implementation of infra-red burner technology.

Survey of Technologies for Web Application Development  

CERN Multimedia

Web-based application developers face a dizzying array of platforms, languages, frameworks and technical artifacts to choose from. We survey, classify, and compare technologies supporting Web application development. The classification is based on (1) foundational technologies; (2)integration with other information sources; and (3) dynamic content generation. We further survey and classify software engineering techniques and tools that have been adopted from traditional programming into Web programming. We conclude that, although the infrastructure problems of the Web have largely been solved, the cacophony of technologies for Web-based applications reflects the lack of a solid model tailored for this domain.

Facts are the enemy of truth-reflections on serendipitous discovery and unforeseen developments in asymmetric catalysis.  

Science.gov (United States)

As Louis Pasteur said, "Chance favors only a prepared mind." Serendipitous events reorienting the pathway of science often occur through the actions of dedicated individuals with unique cultural and educational backgrounds, an original sense of values, and firm principles. Science is the fountainhead of human knowledge and possesses an indispensable cultural value. Science-based technologies and the innovations derived from them are the foundation of the civilized society in which we live today. All scientific endeavors begin with observations, or facts. However, the real goal of research activity is to convert accumulated knowledge to something with new technological, economic, or social value. Innovation is an essential aspect to assure the continued survival of humanity. And often, as my half-century of research reflects, the act of turning facts into values is facilitated by dialogue. Thus, to acquire the necessary combined wisdom, scientists must have ongoing conversations with the societies they serve, as well as with their counterparts in other nations. PMID:23203605

Directory of Open Access Journals (Sweden)

Full Text Available This study demonstrates that the learning channel intervention, utilizing a continuous assessment system, enabled 3 students with special needs to build and generalize fluency in multiplication facts. This study contrasts generalization of 2 learning channels- “see-say” and “hear-say”- to see if either of the 2 channels has an advantage over the other. The data from this study suggests that the particular learning channel was influential in generalization to application. The findings of this study indicate the “hear-say”learning channel has an advantage in the generalization of learning over the “see-say” learning channel. However, this preliminary finding suggests further studies employing a design in which two intervention modes can be alternated in 2 groups of participants.

Developing countries' motivation to use nuclear technology  

International Nuclear Information System (INIS)

Governments of various developing countries see nuclear energy as an important tool for at least three political goals: Firstly, the expected rise in future energy demand, so they argue, can only be met if nuclear electricity production in the Third World is expanded. Fossil sources are supposed to become increasingly scarce and expensive, and they are also seen to be ecologically damaging. Technologies to harness renewable energy sources are not yet mature and still too costly. Secondly, nuclear technology is seen as one of the most advanced technologies. Mastering of it might help to diminish the technological gap between the First and the Third World. Thirdly, scientific progress in developing countries is hoped to be accelerated by operating research reactors in these countries. All of these arguments ought to be taken as serious motivations.

Transfer of radiation technology to developing countries  

International Nuclear Information System (INIS)

The International Atomic Energy Agency, as a United Nations (UN) body, has a mandate to promote nuclear applications and assist Member States in the transfer of technology for peaceful applications. This mandate has been pursued by many different mechanisms developed in the past years: technical assistance, coordinated research programs, scientific and technical meetings, publications, etc. In all these activities the Agency is the organizer and initiator, but main contributions come from expert services from developed countries and, increasingly, from developing countries themselves. The technical cooperation among developing countries contributes more to different programmes. In particular, regional cooperation has been demonstrated as an effective instrument for transfer of technology from developed and among developing countries. (Author).

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.

Crosscutting Technology Development at the Center for Advanced Separation Technologies  

Energy Technology Data Exchange (ETDEWEB)

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.

Commercial development of new electric power technologies  

Energy Technology Data Exchange (ETDEWEB)

This paper examines the commercial prospects of a range of new electric power generating and load management technologies. Drawing on recently completed work at the Office of Technology Assessment, it addresses the current and expected cost and performance of these technologies, their potential contribution to US generating capacity through the 1990's, problems of integration with the electric utility grid and the relative effectiveness of alternative public policy mechanisms for accelerating their rate of development. In addition, the study reviews the investment decision methods of utilities and non-utility power producers and investigates the circumstances under which these technologies could play a significant role in US electric power generation through the 1990's. It focuses on the situation where, due to financial and load growth uncertainty, utilities continue to avoid traditional large scale additions to generating capacity, commitments to which would be necessary very soon to have the capability of meeting increased load growth in the 1990's. With continued deferral of new capacity and if increased load growth does appear in the 1990's, generating technologies with flexible planning features such as short lead times, smaller scale, and modular design would be essential. While many new technologies have these features, at the current rate of development very few of them are likely to be available to contribute substantially in the 1990's. 1 reference, 1 table.

Technology dependent oil development, Troll oil  

Energy Technology Data Exchange (ETDEWEB)

Currently the oil recovery factor in Troll West is 31%, a moderate recovery factor for the North Sea, but still a considerable achievement considering the thin oil column spread out over a large area. Initial oil production from the Oil Province was based on significant improvements in drilling and subsea technology. Further improvements of this technology enabled a full development of the Gas Province and greatly improved the initial oil recovery volume. Technology is still the limiting factor for producing even more of the large volumes of oil to remain in the reservoir according to current plans. This presentation describes key technologies which have enabled large volumes of oil to be recovered from the reservoir.

AECL remediation technology development and demonstration  

International Nuclear Information System (INIS)

Several innovative remediation technologies for the treatment of contaminated soils, groundwater, waste water and organic liquids are being actively pursued at the Chalk River Laboratories of Atomic Energy of Canada Limited. The contamination is usually a mixture of radioactive and hazardous species. The treatment objective is to maximize the recovery of clean material and to minimize the volume of secondary waste arising from the remediation steps. The projects, developed in a laboratory, are tested with actual contaminated materials. The technology is then applied to contaminated sites at Chalk River, to determine its feasibility and to gather information on its efficiency and cost effectiveness. Technology has been developed to remove Sr-90 from groundwater to less than 2 Bq/L. The technology demonstration, initially cost-shared with the United States Department of Energy (USDOE), has now treated in excess of 2 million liters of groundwater. Technology is also available to strip Sr-90 from soil both in situ and ex situ. A treatability study was conducted for the removal of uranium, radium and arsenic from groundwater obtained from a land area contaminated by uranium refining operations. Mixed-waste processing has been developed for the removal of uranium from organics to permit alternative treatment of the separated fractions. A horizontal pulsed column and a more conventional mixer/separator system extract uranium from the organic, to allow recycle of the uranium as yellowcake and to allow destruction of the hazardous organic fraction

This fact sheet describes the purpose, lab specifications, applications scenarios, and information on how to partner with NREL's Manufacturing Laboratory at the Energy Systems Integration Facility. The Manufacturing Laboratory at NREL's Energy Systems Integration Facility (ESIF) focuses on developing methods and technologies that will assist manufacturers of hydrogen and fuel cell technologies, as well as other renewable energy technologies, to scale up their manufacturing capabilities to volumes that meet DOE and industry targets. Specifically, the manufacturing activity is currently focused on developing and validating quality control techniques to assist manufacturers of low temperature and high temperature fuel cells in the transition from low to high volume production methods for cells and stacks. Capabilities include initial proof-of-concept studies through prototype system development and in-line validation. Existing diagnostic capabilities address a wide range of materials, including polymer films, carbon and catalyst coatings, carbon fiber papers and wovens, and multi-layer assemblies of these materials, as well as ceramic-based materials in pre- or post-fired forms. Work leading to the development of non-contact, non-destructive techniques to measure critical dimensional and functional properties of fuel cell and other materials, and validation of those techniques on the continuous processing line. This work will be supported by materials provided by our partners. Looking forward, the equipment in the laboratory is set up to be modified and extended to provide processing capabilities such as coating, casting, and deposition of functional layers, as well as associated processes such as drying or curing. In addition, continuous processes are used for components of organic and thin film photovoltaics (PV) as well as battery technologies, so synergies with these important areas will be explored.

Technology development strategy and the relationship between technology import and domestic research and development (R D)  

Energy Technology Data Exchange (ETDEWEB)

In industrializing as well as industrialized countries, a controversial and complex policy issue concerns the nature and proper balance of the interaction between foreign and indigenous technologies. It is not possible to formulate an effective and timely technological policy without knowing the nature of interaction between foreign and indigenous technologies. The major purpose of this study is to develop a means of understanding the relationship between technology import and domestic research and development. The relationship was expected to be influenced by stage of development and by technology development strategy. A strong complementary relationship was expected for lower stages of development and imitative strategy. A weaker complementary or substitutive relationship was expected for the more advanced countries and aggressive strategy. Although much of the discussion is focused on Japanese and Korean experience in technology development after the Second World War, the statistical analysis of the relationship between technology import and domestic R D encompasses other countries for which relevant data were available. Complementary relationships were found between technology import and domestic R D for Japan, Korea, and France. On the other hand, the relationship between industrial R D and technology import was substitutive for the United States. (The findings were controlled for GNP per capita and number of scientists and engineers). The relationship between technology import and both domestic and industrial R D was independent for West Germany. The statistical findings suggest that the relationship between a country's technology import and its domestic and industrial R D is strongly correlated with its technology development strategy.

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.

In-core thermionic technology development program  

Energy Technology Data Exchange (ETDEWEB)

The purpose of the Defense Special Weapons Agency (DSWA) In-core Thermionic Technology Program is to extend the state of the art of in-core thermionic power conversion in the US. GA is developing three technologies which will lead to a less expensive, high performance, testable multi-cell Thermionic Fuel Element (TFE). A key piece of technology, the emitter trilayer, allows the design of a testable conductively-coupled multi-cell (CC/MC) TFE. This design permits the complete checkout and operation of the TFE and TFE reactor prior to fuel loading. This allows the development of the fuel/clad and of the TFE to occur independently of each other and significantly reduces the cost of TFE fabrication and development testing. It eliminates the costs related to security of fueled TFEs. Another enhancing technology being developed is the fabrication of single crystal tungsten alloys. In previous TFEs, the fuel clad was fabricated from Chemically Vapor Deposited (CVD'd) tungsten. Since emitter deformation is dependent upon the creep strength of the fuel clad, a stronger emitter fuel clad will result in longer fueled emitter lifetime. Single crystal tungsten alloys have the highest creep strength known of any material. The development and manufacture of this alloy will greatly increase the fueled emitter deformation lifetime over existing CVD-Tungsten forms. The third technology being developed is that of oxygenated performance. The introduction of minute amounts of oxygen has been shown to significantly increase the performance of thermionic converters. Most examples of oxygenated performance have been short-lived and transient in nature. Several oxygen-delivery schemes will be investigated and tested which will deliver sustained, reproducible levels of increased performance.

Environmental control technology development for geothermal energy  

Energy Technology Data Exchange (ETDEWEB)

Geothermal energy utilization is a reality in this and many other countries. There is potential for environmental impacts especially from the higher temperature uses. While most environmental impact analysis and controls development has been concentrated at the Geysers, Calif., vapor-dominated resource, the development of liquid-dominated geothermal resources is beginning and environmental issues have begun to arise. Based on information to date, the environmental impacts from geothermal energy utilization can be controlled to acceptable levels using technology presently available for being developed at this time. More operating experience is required, however, before all the environmental impacts and controls are fully defined. Careful monitoring of effluents and an ongoing effort to anticipate and develop control technologies is needed in critical areas where impacts could occur. This approach should be specific to site and application.

Arm development review of existing technologies  

Energy Technology Data Exchange (ETDEWEB)

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)

Next stages in HDR technology development. [Hot Dry Rock (HDR)  

Energy Technology Data Exchange (ETDEWEB)

Twenty years of research and development have brought HDR heat mining technology from the purely conceptual stage to the establishment of an engineering-scale heat mine at Fenton Hill, NM. In April 1992, a long-term flow test (LTFT) of the HDR reservoir at Fenton Hill was begun. The test was carried out under steady-state conditions on a continuous basis for four months, but a major equipment failure in late July forced a temporary suspension of operations. Even this short test provided valuable information and extremely encouraging results as summarized below: There was no indication of thermal drawdown of the reservoir. There was evidence of increasing access to hot rock with time. Water consumption was in the rangki of 10--12%. Measured pumping costs were $0.003 per kilowatt of energy produced. Temperature logs conducted in the reservoir production zone during and after the flow test confirmed the fact that there was no decline in the average temperature of the fluid being produced from the reservoir. In fact, tracer testing showed that the fluid was taking more indirect pathways and thus contacting a greater amount of hot rock as the test progressed. Water usage quickly dropped to a level of 10--15 gallons per minute, an amount equivalent to about 10--12% of the injected fluid volume. At a conversion rate of 10--15%, these would translate to effective fuel costs'' of 2--3[cents] per kilowatt hour of electricity production potential. The completion of the LTFT will set the stage for commercialization of HDR but will not bring HDR technology to maturity. Relatively samples extensions of the current technology may bring significant improvements in efficiency, and these should be rapidly investigated. In the longer run, advanced operational concepts could further improve the efficiency of HDR energy extraction and may even offer the possibility of cogeneration schemes which solve both energy and water problems throughout the world.

Technology development risk assessment and mixed interests  

International Nuclear Information System (INIS)

The main purpose of this work is to demonstrate by means of a critical analysis of the state-of-the-art in technological and environmental risk analysis and decision making, that risk and environmental management decisions involve heterogeneous groups of social actors, each representing conflicting interests. It is argued that risk analyses should therefore be based on social interaction and communication paradigma, as well as, on a new rational way of thinking concerning the optimum choice of suitable technological development strategies leading towards a publicly acceptable balance between national energy-economic strategic necessities and social and individual perception of risk

Development of coal water slurry combustion technologies  

Energy Technology Data Exchange (ETDEWEB)

Currently in the United States, coal accounts for only about 10 percent of the total energy utilized in the industrial market sector, and very little coal is used in the residential and commercial sectors (<10 MMBtu/hr). The development of CWS technology capable of providing a beneficial, easy to handle, low cost coal fuel and the availability of this low cost, maintenance free, environmentally compatible combustion equipment capable of utilizing these fuels, will help stimulate the utilization of domestic coal, reducing the need for foreign oil imports and conserving domestic gas supplies. Based on the results of the system demonstration, the technology is ready for additional demonstrations and commercialization.

Toward An Information And Communication Technology Development In Developing Countries  

Directory of Open Access Journals (Sweden)

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.

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.

Development of Tooling to Support Fact-Oriented Modeling at ESA  

Science.gov (United States)

Developing space systems implies complex activities involving many parties who are widely distributed in location and time. Such development therefore requires efficient and effective information exchange during the complete lifecycle of the space system. This can only be achieved by realizing semantic interoperability between all involved parties. Semantic interoperability can be achieved if the applications involved share a set of conceptual definitions. To achieve this goal, the concept of a global conceptual model that has the potential to embrace the complete lifecycle of a space system is analyzed. Realizing the full potential of this approach requires methods and tools not only to support the formal specification of such a conceptual model and their tailoring for producing application specific conceptual models, but also to support the development or adaptation of applications resulting in needs to support the 3-level data model hierarchy and the ability to specify domain-specific conceptual models based on the global conceptual model. This paper describes the tools that are under development to support the above described objectives.

Economic Development Impacts of Wind Power--Case Studies Fact Sheet  

Energy Technology Data Exchange (ETDEWEB)

OAK-B135 Interest in wind power development is growing as a means of expanding local economies. Such development holds promise as a provider of short-term employment during facility construction and long-term employment from ongoing facility operation and maintenance (O&M). It may also add to the supply of electric power in the area and support some expansion of the local economy through ripple effects resulting from initial increases in jobs and income. These ripple effects stem from subsequent expenditures for goods and services made possible by first-round income from the development, and are expressed in terms of a multiplier. If the local economy offers a wide range of goods and services the resulting multiplier can be substantial--as much as three or four. If not, then much of the initial income will leave the local economy to buy goods and services from elsewhere. Loss of initial income to other locales is referred to as a leakage. While there is a growing body of information about the local impacts of wind power, the economic impacts from existing wind power developments have not been thoroughly and consistently analyzed. Northwest Economic Associates, under contract to the National Wind Coordinating Committee (NWCC), conducted a study and produced a report entitled ''Assessing the Economic Development Impacts of Wind Power.'' The primary objective of the study was to provide examples of appropriate analyses and documentation of economic impacts from wind power development, using case studies of three existing projects in the United States. The findings from the case studies are summarized here; more detail is available in the report, available at NWCC's website http://www.nationalwind.org/. It should be noted that specific results presented apply only to the respective locales studied and are not meant to be representative of wind power in general. However, qualitative findings, discussed below, are likely to be replicated in most areas where wind development occurs.

Halifax company is developing voice recognition technology  

Energy Technology Data Exchange (ETDEWEB)

A newly created Halifax company, called OKAMLogic, was awarded a research contract a few months ago, for the development of voice recognition technology. This contract was jointly awarded by the Canadian Centre for Marine Communications (CCMC) and Aliant Telecom. It is expected that this research will lead to wireless speech recognition and voice authentication applications in the oil and gas industry, as well as the transportation and logistics industries. The technology being developed will allow field workers operating in a remote location to perform functions without the need to use a computer or access the Internet. The access to critical business information would be granted by using a simple voice command from anywhere, anytime. OKAMLogic is working with international wireless companies to develop the product. The consultation work involves the designers from OKAMLogic spending some time in the field to better understand the needs of the workers, such as the time they spent understanding pipeline construction from the viewpoint of Sempra Atlantic Gas. They have gained the recognition of a number or oil and gas players in Atlantic Canada, who are now partnering with the company. Strong partnerships must be established between small companies and the academic and business communities, especially in Atlantic Canada to take advantage of product development, and move to the commercialization of applied research. Company officials are of the opinion that advanced speech and voice systems will revolutionize wireless technology throughout the world. 1 fig.

Development of MOX manufacturing technology in BNFL  

International Nuclear Information System (INIS)

BNFL is successfully operating a small scale MOX fuel fabrication facility at its Sellafield Site and is currently constructing an advanced, commercial scale MOX facility to complement its existing LWR UO2 fabrication capability. BNFL's MOX fuel capability is fully supported by a comprehensive technology development programme aimed at providing a high quality product which is successfully competing in the market. Building on the experience gained over the last 30 years, is from the production of both thermal and fast reactor MOX fuels, BNFL's development team set a standard for its MOX product which is targeted at exceeding the performance of UO2 fuel in reactor. In order to meet the stringent design requirements the product development team has introduced the Short Binderless Route (SBR) process that is now used routinely in BNFL's MOX Demonstration Facility (MDF) and which forms the basis for BNFL's large scale Sellafield MOX Plant. This plant not only uses the SBR process for MOX production but also incorporates the most advanced technology available anywhere in the world for nuclear fuel production. A detailed account of the technology developed by BNFL to support its MOX fuels business will be provided, together with an explanation of the processes and plants used for MOX fuel production by BNFL. The paper also looks at the future needs of the MOX business and how improvements in pellet design can assist the MOX fabrication production process to meet the user demand requirements of utilities around the world.

Development of germline manipulation technologies in livestock  

International Nuclear Information System (INIS)

Genetic improvement by conventional breeding is restricted to those genetic loci present in the parental breeding individuals. Gene addition through transgenic technology offers a route to overcome this restriction. The transgene can be introduced into the germ cells or the fertilized zygote, using viral vectors, by simple co-culture or direct micro-injection. Alternatively, the transgene can be incorporated into a somatic cell, which is then incorporated into a developing embryo. This latter approach allows gene-targeting strategies to be employed. Using pronuclear injection methods, transgenic livestock have been generated with the aim of enhancing breeding traits of agricultural importance, or for biomedical applications. Neither has been taken beyond the development phase. Before they are, in addition to issues of commercial development, basic technological issues addressing inefficiency and complexity of the methodology need to be overcome, and appropriate gene targets identified. At the moment, perhaps the most encouraging development involves the use of viral vectors that offer increased simplicity and efficiency. By combining this new technology with transgenes that evoke the powerful intracellular machinery involved in RNA interference, pioneering applications to generate animals that are less susceptible to infectious disease may be possible.

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 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.

Development of Core Design Technology for LMR  

Energy Technology Data Exchange (ETDEWEB)

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.

Developments in ITM oxygen technology for IGCC  

Energy Technology Data Exchange (ETDEWEB)

In partnership with the U.S. Department of Energy (DOE), an Air Products-led team (with Ceramatec, Eltron Research, McDermott Technology, NREC, Texaco, the Pennsylvania State University, and the University of Pennsylvania) is developing a new technology for air separation - Ion Transport Membrane Oxygen - based on the use of mixed-conducting ceramic membranes that have both electronic and oxygen ionic conductivity when operated at high temperature, typically 800 to 900 C. Under the influence of an oxygen partial-pressure driving force, the ITM Oxygen process achieves a high-purity, high-flux separation of oxygen from a compressed-air stream. By integrating the energy-rich, oxygen-depleted, non-permeate stream with a gas turbine system, the ITM Oxygen process becomes a co-producer of high-purity oxygen, power, and steam. Under a recent CRADA entitled ``Ion Transport Membranes (ITM) for Oxygen-Blown IGCC Systems and Indirect Coal Liquefaction,'' Air Products and DOE completed an initial quantification of the benefits of an ITM Oxygen-integrated IGCC facility. Compared to the cryogenic oxygen base case, the ITM Oxygen technology can potentially: reduce total installed costs by 7%; improve thermal efficiency for the integrated IGCC system by about 3%, leading to further decreases in carbon dioxide and sulfur emissions; and reduce the cost of generated electric power by more than 6%. The ITM Oxygen development project will proceed in three phases. Phase 1, which commenced under a DOE Cooperative Agreement in October 1998, is a 3-year effort focusing on construction of a technology development unit (TDU) for process concept validation tests at a capacity of 0.1 ton-per-day (TPD) oxygen. To accomplish this objective, the Air Products team will address relevant technical challenges in ITM Oxygen materials, engineering, membrane module development, and performance testing. During Phase 1 the team will also verify the economic prospects for integrating ITM Oxygen technology with IGCC and other advanced power generation systems. After at least one intermediate scaleup, Phase 2 and 3 activities will culminate with scaleup to a 25- to 50-TPD pre-commercial demonstration unit, fully integrated with a gas turbine. Meeting these challenges of developing cost-effective fabrication techniques for ITM Oxygen devices, and successfully integrating them with commercially available gas turbine engines, is key to bringing ITM Oxygen technology to the marketplace.

Westinghouse combustion development: 1997 technology update  

Energy Technology Data Exchange (ETDEWEB)

Westinghouse has aggressively incorporated advanced technologies into the combustion system of turbine engines. Focus is on reducing emission levels at increasing firing temperatures. Proactive combustion development programs have resulted in multiple options for achieving substantial reductions in emissions with Dry Low Nox and Ultra Low NO{sub x} combustion systems. This paper presents a description of the program organization, advanced technologies, and results of development efforts to date. The Dry Low NO{sub x} (DLN) combustion system has been demonstrated extensively in the field, including firing with non-standard fuels, such as a refinery waste gases. Improvements have been made to the DLN combustor to reduce the required fuel delivery to the diffusion pilot, thus further reducing NO{sub x} emissions. The Ultra Low NO{sub x} (ULN) system does not require a diffusion pilot at base load and, therefore, can achieve a further reduction in NO{sub x} compared with the DLN combustion system. The ULN combustor is being developed for various combustion turbines, including the new ATS engine. Both combustors were tested in full-scale at atmospheric pressure, mid-pressure and full pressure test facilities. The ULN combustor has been optimized at atmospheric pressure and is being optimized at full pressure. In partnerships with university and government laboratories, advanced combustion technology is being developed to further improve combustor performance. Active and passive noise control are being developed to extend the operating range of the combustors to low NO{sub x} operating conditions that previously would have resulted in unacceptable vibrations. Also, catalytic combustion is being tested to further reduce NO{sub x} and CO emissions. In addition, advanced flame diagnostics are being developed to improve the understanding of combustion processes. Finally, a sequential ignition system is being developed to eliminate the need for cross-flame tubes.

This case study summarizes the economic development benefits to Colorado from four Vestas manufacturing facilities: one in Windsor, two in Brighton, and one in Pueblo (which is planned to be the world's largest tower-manufacturing facility). In the midst of an economic slowdown during which numerous U.S. manufacturers have closed their doors, wind energy component manufacturing is one U.S. industry that has experienced unprecedented growth during the past few years. As demand for wind power in the United States has increased and transportation costs have increased around the world, states have seen a significant increase in the number of manufacturers that produce wind turbine components in the United States. Vestas' Colorado operations will bring approximately $700 million in capital investment and nearly 2,500 jobs to the state.

Development of the advanced CANDU technology -Development of basic technology for HWR design-  

Energy Technology Data Exchange (ETDEWEB)

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.

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

NREL Determines Better Testing Methods for Photovoltaic Module Durability (Fact Sheet), NREL Highlights, Research & Development  

Energy Technology Data Exchange (ETDEWEB)

NREL discoveries will enable manufacturers to produce more robust photovoltaic modules. Over the past decade, some photovoltaic (PV) modules have experienced power losses because of the system voltage stress that modules experience in fielded arrays. This is partly because qualification tests and standards do not adequately evaluate the durability of modules that undergo the long-term effects of high voltage. Scientists at the National Renewable Energy Laboratory (NREL) tried various testing methods and stress levels to demonstrate module durability to system voltage potential-induced degradation (PID) mechanisms. The results of these accelerated tests, along with outdoor testing, were used to estimate the acceleration factors needed to more accurately evaluate the durability of modules to system voltage stress. NREL was able to determine stress factors, levels, and methods for testing based on the stresses experienced by modules in the field. These results, in combination with those in the literature, suggest that constant stress with humidity and system voltage is more damaging than stress applied intermittently or with periods of recovery comprising hot and dry conditions or alternating bias in between. NREL has determined some module constructions to be extremely durable to PID. These findings will help the manufacturers of PV materials and components produce more durable products that better satisfy their customers. NREL determined that there is rapid degradation of some PV modules under system voltage stress and evaluated degradation rates in the field to develop more accurate accelerated testing methods. PV module manufacturers will be better able to choose robust materials and durable designs and guarantee sturdier, longer-lasting products. As PV modules become more durable, and thus more efficient over the long term, the risks and the cost of PV power will be reduced.

Strategies of the future technological development  

International Nuclear Information System (INIS)

Attempt to formulate strategies of the future development are formulated based on raw materials for energy needs, which will be in our disposal for the interval up to the start of nuclear fast breeder reactors. Main tendencies should be broader nuclear energy use and nonelectric application. As an externally given boundary condition it is supposed that world society model will be kept as a continuity of mankind history. There are recommendation of the demands for the development of new technologies to substitute decreasing external fossil energy resources and generally growing demand for living standard. Most of the considerations are growing from the INPRO studies published in IAEA Vienna. (Author)

Medically relevant ElectroNeedle technology development.  

Energy Technology Data Exchange (ETDEWEB)

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.

Facts First  

Energy Technology Data Exchange (ETDEWEB)

I enjoy reading online news and opinions not only because of convenience, but also because of the responses from the readers. I know that these responses tend to be biased towards the extremes of opinions, but it is always interesting to see the diverse reactions from even seemingly non-controversial subjects. A recent example was the response to an editorial by Richard Gallaghar (October, 2008) that proffered the seemingly obvious opinion that science students need a strong understanding of scientific history and philosophy to help them face future challenges. This provoked a response from a reader, a college professor, that a major reason for the lack of good university science education was the laziness of his colleagues. They were taking the “easy way out” by concentrating on teaching facts rather than scientific concepts. In the respondent’s viewpoint, it was far better to teach students how to think. Facts could always be looked up in textbooks. If you did not understand how to think critically and create knowledge, you could not be considered educated. Although I am very sympathetic to this point of view, I don’t believe that laziness is the reason why students are flooded with facts rather than concepts in biology class.

Development of spent fuel remote handling technology  

International Nuclear Information System (INIS)

[en] 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

Development of Solid State Laser Technology  

International Nuclear Information System (INIS)

Recently, diode-pumped solid state lasers(DPSSL) have been developed to have a diffraction limited beam quality and high average output powers beyond kW. The lifetime extends to have several thousand hours. Due to such merits, the DPSSLs are now replacing previous application fields of CO2 laser, lamp-pumped solid-state lasers, Excimer laser, etc. The DPSSLs have broad application fields, such as laser spectroscopy and analysis, laser micromachining, precision measurement, laser range findings, laser pump sources, medical lasers, etc. In this project, various DPSSLs are developed for use in laser isotope production. Many new laser modules are designed and used to develop high power pulsed IR lasers and green lasers.

Environmental technology development through industry partnership  

Energy Technology Data Exchange (ETDEWEB)

The Coherent Laser Vision System (CLVS) is being developed to provide precision real-time 3D world views to support site characterization and robotic operations and during facilities Decontamination and Decommissioning. Autonomous or semiautonomous robotic operations requires an accurate, up-to-date 3D world view. Existing technologies for real-time 3D imaging, such as AM laser radar, have limited accuracy at significant ranges and have variability in range estimates caused by lighting or surface shading. Recent advances in fiber optic component technology and digital processing components have enabled the development of a new 3D vision system based upon a fiber optic FMCW coherent laser radar. The approach includes a compact scanner with no-moving parts capable of randomly addressing all pixels. The system maintains the immunity to lighting and surface shading conditions which is characteristic to coherent laser radar. The random pixel addressability allows concentration of scanning and processing on the active areas of a scene, as is done by the human eye-brain system. The precision measurement capability of the coherent laser radar (CLR) technology has already been demonstrated in the form of the CLR 3D Mapper, of which several copies have been delivered or are under order. The CLVS system, in contrast to the CLR 3D Mapper, will have substantially greater imaging speed with a compact no-moving parts scanner, more suitable for real-time robotic operations.

Hydraulic hammer drilling technology: Developments and capabilities  

Energy Technology Data Exchange (ETDEWEB)

Percussion drilling technology was considered many years ago as one of the best approaches for hard rock drilling. Unfortunately the efficiency of most hydraulic hammer (HH) designs was very low (8% maximum), so they were successfully used in shallow boreholes only. Thirty years of research and field drilling experience with HH application in Former Soviet Union (FSU) countries led to the development of a new generation of HH designs with a proven efficiency of 40%. That advance achieved good operational results in hard rock at depths up to 2,000 m and more. The most recent research has shown that there are opportunities to increase HH efficiency up to 70%. This paper presents HH basic design principles and operational features. The advantages of HH technology for coiled-tubing drilling is shown on the basis of test results recently conducted in the US.

Engineering research, development and technology FY99  

Energy Technology Data Exchange (ETDEWEB)

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.

Developments in precision optical grinding technology  

Science.gov (United States)

Optical systems that utilize complex optical geometries such as aspheres and freeform optics require precise control through the manufacturing process. As the preparatory stage for polishing, this is especially true for grinding. The quality of the grinding process can greatly influence the polishing process and the resultant finished product. OptiPro has performed extensive development work in evaluating components of a precision grinding machine to determine how they influence the overall manufacturing process. For example, spindle technology has a strong effect on how a grinding machine will perform. Through metrology techniques that measure the vibration characteristics of a machine and measurements of grinding forces with a dynamometer, OptiPro has also developed a detailed knowledge of how the machine can influence the grinding process. One of the outcomes of this work has led OptiPro to develop an ultrasonic head for their grinding platform to aid in reducing grinding forces. Initial results show a reduction in force by ~50%.

The analysis highlights the following six key considerations for the development of policy aimed at facilitating low carbon technology transfer to developing countries: (1) technology transfer needs to be seen as part of a broader process of sustained, low carbon technological capacity development in recipient countries; (2) the fact that low carbon technologies are at different stages of development means that low carbon technology transfer involves both vertical transfer (the transfer of technologies from the R and D stage through to commercialisation) and horizontal transfer (the transfer from one geographical location to another). Barriers to transfer and appropriate policy responses often vary according to the stage of technology development as well as the specific source and recipient country contexts; (3) less integrated technology transfer arrangements, involving, for example, acquisition of different items of plant from a range of host country equipment manufacturers, are more likely to involve knowledge exchange and diffusion through recipient country economies; (4) recipient firms that, as part of the transfer process, strategically aim to obtain technological know-how and knowledge necessary for innovation during the transfer process are more likely to be able to develop their capacity as a result; (5) whilst access to Intellectual Property Rights (IPRs) may sometimes be a necessary part of facilitating technology transfer, it is not likely to be sufficient in itself. Other factors such as absorptive capacity and risks associated with new technologies must also be addressed; (6) there is a central role for both national and international policy interventions in achieving low carbon technology transfer. The lack of available empirical analysis on low carbon technology transfer, coupled with the prominence of the issue within international climate negotiations, suggests an urgent need for further research effort in this area.

Development of spent fuel remote handling technology  

Energy Technology Data Exchange (ETDEWEB)

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.

Chemical sensors technology development planning workshop  

Energy Technology Data Exchange (ETDEWEB)

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&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&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.

CROSSCUTTING TECHNOLOGY DEVELOPMENT AT THE CENTER FOR ADVANCED SEPARATION TECHNOLOGIES  

Energy Technology Data Exchange (ETDEWEB)

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.

Technology development for nuclear material accountability  

International Nuclear Information System (INIS)

A positive on-site verification technique of spent PWR fuel rods in pool at PIEF and a program for MUF evaluation in bulk material handling facility were developed in support of facility operation and IAEA verification activity. When spent fuel was measured by gamma-ray spectrometry the measured intensity of Cs-137 662 KeV gamma-ray from the sample was clearly identified against comparing background. By the MCNP code simulations, the flux of 662 KeV gamma-ray in the collimated rod was also different from that from the adjacent one. Base on this fact it is possible to identify spent fuel without having a rod pulled out of assembly in spent pond. This method may be useful as a spent fuel verification tool for both IAEA and facility operator. It may also contribute to the reduction of manpower and operational time. A system for facility MUF evaluation was established to apply it to the bulk material handling facility. With required input data the evaluation program was run to produce final results for evaluation of the soundness of MUF. This program was tested with real input data from CANDU fuel fabrication facility in KAERI. The outcome showed that sigma MUF was not significant to sigma international but MUF was found to be statistically significant as compared to critical value at 95% confidence interval. (Author)

International Nuclear Information System (INIS)

We have been studying small, driven fusion reactors as candidates for a Technology Development Facility (TDF) to be used for testing reactor subsystems, components, and materials. Magnetic mirror systems are particularly interesting for this application because of their inherent steady-state operation, potentially high wall loading, and relatively small size. The systems so far studied have 14-MeV neutron wall loads ranging from 1 to 3 MW m-2 on testing surface areas of 2 to 5 m2 with annual fluences as high as 1021 neutrons cm-2. These devices are based on physics and engineering that has been demonstrated or is scheduled for demonstration in the next year

Energy technology progress for sustainable development  

Energy Technology Data Exchange (ETDEWEB)

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.

THz spectroscopy: An emerging technology for pharmaceutical development and pharmaceutical Process Analytical Technology (PAT) applications  

Science.gov (United States)

As an emerging technology, THz spectroscopy has gained increasing attention in the pharmaceutical area during the last decade. This attention is due to the fact that (1) it provides a promising alternative approach for in-depth understanding of both intermolecular interaction among pharmaceutical molecules and pharmaceutical product quality attributes; (2) it provides a promising alternative approach for enhanced process understanding of certain pharmaceutical manufacturing processes; and (3) the FDA pharmaceutical quality initiatives, most noticeably, the Process Analytical Technology (PAT) initiative. In this work, the current status and progress made so far on using THz spectroscopy for pharmaceutical development and pharmaceutical PAT applications are reviewed. In the spirit of demonstrating the utility of first principles modeling approach for addressing model validation challenge and reducing unnecessary model validation "burden" for facilitating THz pharmaceutical PAT applications, two scientific case studies based on published THz spectroscopy measurement results are created and discussed. Furthermore, other technical challenges and opportunities associated with adapting THz spectroscopy as a pharmaceutical PAT tool are highlighted.

Reprocessing technology development for irradiated beryllium  

Energy Technology Data Exchange (ETDEWEB)

At present, beryllium is under consideration as a main candidate material for neutron multiplier and plasma facing material in a fusion reactor. Therefore, it is necessary to develop the beryllium reprocessing technology for effective resource use. And, we have proposed reprocessing technology development on irradiated beryllium used in a fusion reactor. The preliminary reprocessing tests were performed using un-irradiated and irradiated beryllium. At first, we performed beryllium separation tests using un-irradiated beryllium specimens. Un-irradiated beryllium with beryllium oxide which is a main impurity and some other impurities were heat-treated under chlorine gas flow diluted with Ar gas. As the results high purity beryllium chloride was obtained in high yield. And it appeared that beryllium oxide and some other impurities were removed as the unreactive matter, and the other chloride impurities were separated by the difference of sublimation temperature on beryllium chloride. Next, we performed some kinds of beryllium purification tests from beryllium chloride. And, metallic beryllium could be recovered from beryllium chloride by the reduction with dry process. In addition, as the results of separation and purification tests using irradiated beryllium specimens, it appeared that separation efficiency of Co-60 from beryllium was above 96%. It is considered that about 4% Co-60 was carried from irradiated beryllium specimen in the form of cobalt chloride. And removal efficiency of tritium from irradiated beryllium was above 95%.

Technology development needs summary, FY 1995  

Energy Technology Data Exchange (ETDEWEB)

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.

Current Status of VHTR Technology Development  

Energy Technology Data Exchange (ETDEWEB)

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.

The following issues are presented: Nuclear technology, safety and security (including non-proliferation and protection against terrorism); Environmental aspects (including greenhouse gas emissions of the nuclear energy lifecycle); Nuclear power and the power market (including impact of nuclear power on electricity market prices); Economic aspects (including costs of nuclear power and external costs and benefits); Policy issues (including sustainable development); Social acceptance of nuclear energy; Knowledge infrastructure for nuclear energy in the Netherlands; and Nuclear power in long term energy scenarios for the Netherlands and Europe. Using two long-term energy scenarios the report also presents a social impact analysis of an increasing share of nuclear power in the Dutch electricity supply. [Dutch] In dit onderzoek zijn feiten en gegevens over kernenergie verzameld op basis van bestaande inzichten en een veelheid aan literatuur (fact finding). Voor technologische expertise heeft ECN zich laten bijstaan door de Nucleair Research and consultancy Group (NRG). Op basis van de fact-finding studie bereidt de SER een advies voor over de rol van kernenergie in de toekomstige nationale elektriciteitsproductie. In de eerste acht hoofdstukken worden feiten en gegevens gepresenteerd over verschillende onderwerpen die bij kernenergie van belang zijn. In Hoofdstuk 2 wordt de kernenergietechnologie beschreven, inclusiefde veiligheid van kernenergie besproken, omdat die nauw met de technologie samenhangt. Hierbij gaat het om de technische veiligheid van de installaties, maar ook om beveiliging tegen misbruik van technologie en nucleair materiaal, waaronder beveiliging tegen terrorisme. De milieuaspecten door radioactiviteit en door emissies van kooldioxide die met het gebruik van kernenergie samenhangen worden in Hoofdstuk 3 besproken. In hoofdstuk 4 wordt eerst uitgelegd hoe de elektriciteitsprijs in een geliberaliseerde elektriciteitsmarkt tot stand komt en wordt nagegaan of uitbreiding van het productievermogen met kernenergie daar invloed op zou kunnen hebben. Ook wordt de concurrentie met andere elektriciteitsproductietechnologieen besproken. Verder komen mededingingsaspecten aan de orde en inpassing in het Nederlandse elektriciteitssysteem. In Hoofdstuk 5 wordt een overzicht gegeven van kosteninformatie over kernenergie. Daarnaast wordt de economische rentabiliteit van kernenergie besproken, evenals externe kosten en baten. In Hoofdstuk 6 wordt eerst ingegaan op de vraag aan welke voorwaarden kernenergie moet voldoen om een rol te kunnen spelen in (een overgangsfase naar) een duurzame energievoorziening. Hierna wordt de rol van de overheid besproken bij het maken van keuzes over voorwaarden van kernenergie en het vertalen daarvan in wet- en regelgeving. Ook wordt een overzicht gegeven van het kernenergiebeleid in een aantal andere Europese landen. Hoofdstuk 7 gaat over maatschappelijke acceptatie en bespreekt hoe risicoperceptie van kernenergie wordt onderzocht. Daarnaast worden resultaten gepresenteerd van onderzoek naar opvattingen en meningen van de bevolking over kernenergie. In Hoofdstuk 8 wordt de Nederlandse kennisinfrastructuur op het gebied van kernenergie beschreven, alsmede de nucleaire kennis bij de overheid en de toekomstige kennisinfrastructuur. Hoofdstuk 9 geeft een overzicht van verschillende Nederlandse en Europese lange termijn toekomstscenario's voor de elektriciteitsvoorziening en de rol die kernenergie daarin kan spelen. Om een beeld te kunnen geven van mogelijke maatschappelijke gevolgen van uitbreiding van kernenergie in Nederland, is een maatschappelijke impact analyse uitgevoerd. Een dergelijke analyse beschrijft op systematische wijze de mogelijke economische en sociale effecten van een nieuwe kerncentrale en de effecten op het milieu. De resultaten van deze analyse worden beschreven in Hoofdstuk 10. Bij de analyse is gebru

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

Development of advanced LWR fuel pellet technology  

Energy Technology Data Exchange (ETDEWEB)

A UO{sub 2} pellet was designed to have a grain size of larger than 12 {mu}m, and a new duplex design that UO{sub 2}-Gd{sub 2}O{sub 3} is in the core and UO{sub 2}-Er{sub 2}O{sub 3} in the periphery was proposed. A master mixing method was developed to make a uniform mixture of UO{sub 2} and additives. The open porosity of UO{sub 2} pellet was reduced by only mixing AUC-UO{sub 2} powder with ADU-UO{sub 2} 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 UO{sub 2} sintering, the relations between sintering variables (additive, sintering gas, sintering temperature) and pellet properties (density, grain size, pore size) were experimentally found. The UO{sub 2}-U{sub 3}O{sub 8} powder which is inherently not sinterable to high density could be sintered well with the aid of additives. U{sub 3}O{sub 8} single crystals were added to UO{sub 2} powder, and homogeneous powder mixture was pressed and sintered in a reducing atmosphere. This technology leads to a large-grained pellet of 12-20 {mu}m. In UO{sub 2}-Gd{sub 2}O{sub 3} 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 UO{sub 2} 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)

Integrated diesel engine NOx reduction technology development  

Energy Technology Data Exchange (ETDEWEB)

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.

Recent developments in optical neuromodulation technologies.  

UK PubMed Central (United Kingdom)

The emergence of optogenetics technology facilitated widespread applications for interrogation of complex neural networks, such as activation of specific axonal pathways, previously found impossible with electrical stimulation. Consequently, within the short period of its application in neuroscience research, optogenetics has led to findings of significant importance both during normal brain function as well as in disease. Moreover, the optimization of optogenetics for in vivo studies has allowed the control of certain behavioral responses such as motility, reflex, and sensory responses, as well as more complex emotional and cognitive behaviors such as decision-making, reward seeking, and social behavior in freely moving animals. These studies have produced a wide variety of animal models that have resulted in fundamental findings and enhanced our understanding of the neural networks associated with behavior. The increasing number of opsins available for this technique enabled even broader regulation of neuronal activity. These advancements highlight the potential of this technique for future treatment of human diseases. Here, we provide an overview of the recent developments in the field of optogenetics technology that are relevant for a better understanding of several neuropsychiatric and neurodegenerative disorders and may pave the way for future therapeutic interventions.

Development of solid oxide fuel cell technology  

International Nuclear Information System (INIS)

Solid Oxide Fuel Cell (SOFC) technologies that use zirconium oxide as the electrolyte material were studied in this present report. SOFC exhibits a very high power generation efficiency of over 50 %, and does not discharge pollution materials such as dusts, sulfur dioxide, and nitrogen oxide. Zirconia, Ni/YSZ (yttria stabilized zirconia), and La-Sr-Mn-Oxide materials were developed for the electrolyte material, for the anode, and for the cathode, respectively. After making thin zirconia plate using tape casting process, anode and cathode powders were screen printed on the zirconia plate for fabricating unit cells. A test system composed of a vertical tube furnace, digital multimeter, DC current supplier, and measuring circuit was constructed for testing the unit cell performance. This system was controlled by a home-made computer program. Founded on this unit cell technology and system, a multi-stack SOFC system was studied. This system was composed of 10 unit cells each of them had an electrode area of 40 x 40 mm. Based on this system design, large and thin zirconia plates of 70 x 70 mm in area was fabricated for the electrolyte. Different from in the unit cell system, interconnectors are needed in the multi-stack system for connecting unit cells electrically. For this interconnectors, Inconel 750 alloy was selected, sliced into wafers, machined, surface finished, and then Pt-plated. 55 figs, 8 tabs, 51 refs. (Author).

We have been studying small, driven fusion reactors as candidates for a Technology Development Facility (TDF) to be used for testing reactor subsystems, components, and materials. Magnetic mirror systems are particularly interesting for this application because of their inherent steady-state operation, potentially high wall loading, and relatively small size. The systems so far studied have 14-MeV neutron wall loads ranging from 1 to 3 MW m/sup -2/ on testing surface areas of 2 to 5 m/sup 2/ with annual fluences as high as 10/sup 21/ neutrons cm/sup -2/. These devices are based on physics and engineering that has been demonstrated or is scheduled for demonstration in the next year.

Energy Technology Data Exchange (ETDEWEB)

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).

Technology development for DUPIC process safeguards  

Energy Technology Data Exchange (ETDEWEB)

As the strategy for DUPIC(Direct Use of spent PWR fuel In CANDU reactor) process safeguards, the neutron detection method was introduced to account for nuclear materials in the whole DUPIC process by selectively measuring spontaneous fission neutron signals from {sup 244}Cm. DSNC was designed and manufactured to measure the account of curium in the fuel bundle and associated process samples in the DUPIC fuel cycle. The MCNP code had response profile along the length of the CANDU type fuel bundle. It was found experimentally that the output signal variation due to the overall azimuthal asymmetry was less than 0.2%. The longitudinal detection efficiency distribution at every position including both ends was kept less than 2% from the average value. Spent fuel standards almost similar to DUPIC process material were fabricated from a single spent PWR fuel rod and the performance verification of the DSNC is in progress under very high radiation environment. The results of this test will be eventually benchmarked with other sources such as code simulation, chemical analysis and gamma analysis. COREMAS-DUPIC has been developed for the accountability management of nuclear materials treated by DUPIC facility. This system is able to track the controlled nuclear materials maintaining the material inventory in near-real time and to generate the required material accountability records and reports. Concerning the containment and surveillance technology, a focused R and D effort is given to the development of unattended continuous monitoring system. Currently, the component technologies of radiation monitoring and surveillance have been established, and continued R and D efforts are given to the integration of the components into automatic safeguards diagnostics.

Molten nitrate salt technology development status report  

Energy Technology Data Exchange (ETDEWEB)

Recognizing thermal energy storage as potentially critical to the successful commercialization of solar thermal power systems, the Department of Energy (DOE) has established a comprehensive and aggressive thermal energy storage technology development program. Of the fluids proposed for heat transfer and energy storage molten nitrate salts offer significant economic advantages. The nitrate salt of most interest is a binary mixture of NaNO/sub 3/ and KNO/sub 3/. Although nitrate/nitrite mixtures have been used for decades as heat transfer and heat treatment fluids the use has been at temperatures of about 450/sup 0/C and lower. In solar thermal power systems the salts will experience a temperature range of 350 to 600/sup 0/C. Because central receiver applications place more rigorous demands and higher temperatures on nitrate salts a comprehensive experimental program has been developed to examine what effects, if any, the new demands and temperatures have on the salts. The experiments include corrosion testing, environmental cracking of containment materials, and determinations of physical properties and decomposition mechanisms. This report details the work done at Sandia National Laboratories in each area listed. In addition, summaries of the experimental programs at Oak Ridge National Laboratory, the University of New York, EIC Laboratories, Inc., and the Norwegian Institute of Technology on molten nitrate salts are given. Also discussed is how the experimental programs will influence the near-term central receiver programs such as utility repowering/industrial retrofit and cogeneration. The report is designed to provide easy access to the latest information and data on molten NaNO/sub 3//KNO/sub 3/ for the designers and engineers of future central receiver projects.

Development of Advanced LWR Fuel Pellet Technology  

International Nuclear Information System (INIS)

[en] 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

The main purpose of this study is to develop the technology associated to detect the skin contamination by hot particles, to improve skin dose assessment methodology, and to propose the procedures for hot particle control in order to assure the safety of the radiation workers. The study included the review of the skin structure, the possible stochastic and deterministic effects when exposed to the radiation, and the threshold dose below which such effects do not occur. The study also recommended the appropriate regulatory guider lines that help the control of the skin contamination by reviewing the recommendations stated in ICRP and the relevant regulation employed in korea currently. The physical and radiological characteristics of the hot particle were also reviewed. Finally, the hot particle detection and control procedures and the skin dose evaluation methodology were developed in this study. Therefore, by applying the methodologies or procedures developed in this study, it is believed that we can greatly improve the hot particle control, can minimize the hot particle contamination of the radiation workers and can estimate the skin dose more accurately.

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

Simulator Developed to Drastically Reduce Time of Multijunction PV Device Efficiency Measurements (Fact Sheet), NREL Highlights, Research & Development  

Energy Technology Data Exchange (ETDEWEB)

NREL's new simulator helps speed up research in the race to improve photovoltaic efficiency. Scientists at the National Renewable Energy Laboratory (NREL) needed a quick and accurate method to predict energy generated from multijunction photovoltaic (PV) test devices. This method had to take into account the nonlinear behavior of multijunction PV. NREL achieved this by developing the One-Sun Multi-Source Simulator (OSMSS), which reduces the time for this type of reference spectrum efficiency measurement from hours or days to minutes. The OSMSS is an automated, spectrally adjustable light source that builds a unique simulator spectrum that causes a multijunction PV device to behave as it would under a reference spectrum. This new simulator consists of four light sources separated into nine wavelength bands between 350 and 2,000 nm. The irradiance in each band is adjustable from zero to about 1.5 suns. All bands are recombined via optical fibers and integrating optics to produce a nearly 10 cm x 10 cm uniform spot. The operator simply links the OSMSS to the quantum efficiency data for the test device, and the OSMSS does the rest. The OSMSS can also determine the power as a function of the spectral irradiance (beyond the reference spectra), total irradiance, and temperature. Major components of the system were built to NREL specification by LabSphere, Inc. NREL developed a new, fully automated tool that rapidly builds a spectrum under which all junctions of a multijunction PV device behave as they would under a reference spectrum. Such a spectrum is essential to properly characterize multijunction devices. The OSMSS reduces the time for building spectra for current vs. voltage measurements from hours or days to minutes. This makes it possible to quickly characterize a multijunction device under many different conditions. The OSMSS will be an important tool to help predict the yearly energy output of a multijunction PV device in a particular environment when provided with a range of spectra and temperatures for that location.

Energy Choices. Choices for future technology development  

International Nuclear Information System (INIS)

[en] 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

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 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 required for targeting somatic cells (the

Cellulosic ethanol. Potential, technology and development status  

Energy Technology Data Exchange (ETDEWEB)

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.

Development of high spectral resolution lidar (HSRL) technology. Final report  

Energy Technology Data Exchange (ETDEWEB)

This report describes progress achieved during two years of DOE funding provided by grant DE-FG02-90ER61058. This grant was titled {open_quotes}Development of High Spectral Resolution Lidar Technology for use in the DOE ARM Program{close_quotes}. Nearly all grant objectives were achieved despite the fact that DOE abruptly canceled funding after only two years of a planned three year effort. The principal investigator learned of the cancellation only after attempting to determine why third year funding had not arrived. This occurred two weeks into the planned third year. The unexpected loss of funds created destructive dislocations in our research program. This report describes only progress during the two funded years. Subsequent research. funded by other sources, has resulted in High Spectral Lidar System performance well in excess of that proposed in the DOE program. This system has proven its performance in routine observations at the University of Wisconsin and during an extended field deployment as part of a winter storms project in Arizona.

Development of CANFLEX fuel fabrication technology  

Energy Technology Data Exchange (ETDEWEB)

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.

Development of computational spacer patterning technology  

Science.gov (United States)

Computational spacer patterning technology (SPT) has been developed for the first time to address the challenges concerning hotspots and mask specifications in SPT. A simulation combined with a lithography, etching and deposition model shows the strong correlation of 0.999, 0.993, 0.980 with the experimental critical dimension (CD), mask error-enhancement factor (MEEF) and defect printability through a series of spacer processes, respectively. Furthermore, a design for manufacturability (DfM) flow using computational SPT can find hotspots caused by spacer patterning processes as well as those caused by lithography process and help designers make the circuit layout more robust. Besides, a newly defined MEEF and defect printability, which are primary metrics for mask specification, can be predicted so accurately by using computational SPT that the new scheme to determine appropriate mask specifications is shown to be feasible under the spacer patterning process condition. Thus, computational SPT is found to be promising for addressing the challenges concerning hotspot removal and mask specification in the upcoming 20-30nm node and beyond.

International Nuclear Information System (INIS)

High power proton accelerator is considered as one of national fundamental research facilities and a key to advanced nuclear technology development, having been widely used in an un detachable relationship with nuclear research in advanced countries. The high power proton accelerator will be installed in several phases as an up front facility of the nuclear waste transmutation system. It is expected that a common understanding and a general agreement over proper utilization of the accelerator should be deduced and that a user program for beam utilization and application should be firmly established in time for the completion of each phase of the accelerator. This high power proton accelerator will consist of several component accelerators and, from up front, accelerators such as injector, RFQ, CCDTL, etc. will be installed in sequence and deliver respectively at each stage beams of 3MeV, 20MeV, 100Mev, etc. to be variously utilized for industries, defence industry, medical treatment, environmental protection and basic science research. In order for the accelerator to be fully utilized as a national fundamental research facility beyond nuclear field, it is necessary to formulate a proceeding plan of the user program for the accelerator and to cultivate industrial utilization/application studies of proton beams accelerated by injector or RFQ of the accelerator.

[en] 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.

Thermoelectric Development at Hi-Z Technology  

Energy Technology Data Exchange (ETDEWEB)

An improved Thermoelectric Generator (TEG) for the Heavy Duty Class Eight Diesel Trucks is under development at Hi-Z Technology. The current TEG is equipped with the improved HZ-14 Thermoelectric module, which features better mechanical properties as well as higher electric power output. Also, the modules are held in place more securely. The TEG is comprised of 72 TE modules, which are capable of producing 1kW of electrical power at 30 V DC during nominal engine operation. Currently the upgraded generator has completed testing in a test cell and starting from August 2001 will be tested on a Diesel truck under typical road and environmental conditions. It is expected that the TEG will be able to supplement the existing shaft driven alternator, resulting in significant fuel saving, generating additional power required by the truck?s accessories. The electronic and thermal properties of bulk materials are altered when they are incorporated into quantum wells. Two-dimensional quantum wells have been synthesized by alternating layers of B4C and B9C in one system and alternating layers of Si and Si0.8Ge0.2 in another system. Such nanostructures are being investigated as candidate thermoelectric materials with high figures of merit (Z). The predicted enhancement is attributed to the confined motion of charge carriers and phonons in the two dimensions and separating them from the ion scattering centers. Multilayer quantum well materials development continues with the fabrication of thicker films, evaluation of various substrates to minimize bypass heat loss, and bonding techniques to minimize high contact resistance. Quantum well thermoelectric devices with N-type Si/Si0.8Ge0.2 and P-type B4C/B9C have been fabricated from these films. The test results generated continue to indicate that much higher thermoelectric efficiencies can be achieved in the quantum wells compared to the bulk materials.

Qin Shan 300 MWe PWR and Da Ya Bay 2x900 MWe PWR are under construction. They mark the beginning of the nuclear power programme of China. However, there are not enough uranium resources in China according to recent exploration. As we know the uranium resources in China that could be used for civil applications would be sufficient to provide fuel only for about 15 GWe for 30 years in the case of thermal reactors operating on the one-through cycle (based on U-235), that is the reason why China is interested in the development of fast breeder reactors. Since the late 1960s, a small group of people has begun the basic research work on FBR in China with only a small amount of funds and material resources. The emphasis of research work was put on the core neutronic physics, thermo-hydraulics, sodium purification and impurity analysis, compatibility of materials with sodium and some sodium facilities on a small scale. So far more than ten miniature sodium loops and facilities have been set up. As the first step of FBR technology development in China, we plan to construct an experimental fast reactor of 25-50 MWe around 2000 to get experience in FBR design construction and operation. The main technical options and some initial design boundary conditions have been preliminarily decided for this reactor. (author). 1 ref., 2 figs, 4 tabs

Development of Sodium Technology for LMR  

International Nuclear Information System (INIS)

In the experiments to investigate the characteristics of the free surface fluctuation in a vessel, the experimental correlation was modeled to describe the free surface fluctuation in the upper plenum of a liquid metal reactor within 95% reliability and 2.4% error. The correlation was used to verify the computational model. The new conceptual flowmeters were suggested to measure the sodium flow for the reliability enhancement. The electromagnetic flowmeter with permanent magnet showed a good linearity and repeatability. For reuse of the sodium contaminated component, CO2 bubbling method was developed. Sodium in 0.3mm crevice specimen was removed completely. The optimum condition for the used sodium treatment was deduced to estimate which reaction is more safe and adequate for operation condition by analyzing the reactivity alleviation condition and the reaction rate with the control of sodium hydroxide concentration A series of tests were carried out to investigate the enlargement rate of the nozzle hole itself and the sodium-water reaction temperature associated with needle-like jets of a high-pressure water/steam into the sodium side of a steam generator. The size of the nozzle hole became larger with an increased duration of the steam injection both for the 2.25Cr-1Mo and M9Cr-1Mo steels by a self-wastage phenomenon. For developing the SWR acoustic leak detection technology, the tool prepared by the LabVIEW was installed with the system, and confirmed the performance of the on-line acoustic leak detection tool using the SWR leak signal acquired in the KAERI facility.

Systems engineering identification and control of mixed waste technology development  

Energy Technology Data Exchange (ETDEWEB)

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.

Casting Technology Development for SFR Metallic Fuel  

International Nuclear Information System (INIS)

[en] 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 vacuum-assisted gravity casting technique for an irradiation test in the HANARO research reactor from 2010. (authors)

The transfer of technological know-how to developing countries: Technology licensing, tacit knowledge, and the acquisition of technological capability  

Energy Technology Data Exchange (ETDEWEB)

Indian technology policy appears to have been based on the promise that though technology imports are important for growth, it could hinder technological effort in the recipient country. A model with two technology importing firms and a technical input supplying domestic sector competing with technology suppliers in the developed world is analyzed. Domestic purchases convey a beneficial externality on other users so that the resulting market outcome is inefficient. However, absent synergies between technological efforts of users and the learning activities in the domestic technical input sector, restricting technology imports will not encourage domestic technological efforts. The empirical literature suggests that technological efforts and technology imports are complements. Many of these econometric studies on the subject are found to suffer from methodological problems. A unifying framework and a simple way of testing for complementarities between decision variables using reduced form regressions is provided.

Mixed waste integrated program problem-oriented technology development  

Energy Technology Data Exchange (ETDEWEB)

Is responsible for the management and treatment of its mixed low-level wastes (MLLW). Over the next 5 years, DOE will manage over 1.2 m{sup 3} of MLLW and mixed transuranic (MTRU) wastes. Although technology to treat MLLW is not currently available without modification, DOE is committed to developing such treatment technologies and demonstrating them at the field scale by FY 1997. MWIP advocates and sponsors expedited technology development and demonstrations for the treatment of MLLW. MWIP encourages appropriate public participation in the development and demonstration of its technologies. Therefore, the structure of MWIP reflects the two-pronged approach that is required for mixed waste technology development: (1) demonstration/commercialization-user, stakeholder, and regulator interfaces facilitate technology demonstration and support implementation in a systems context; and (2) technology development. Technology development is ongoing in technical areas required to process mixed waste: materials handling, chemical/physical treatment, waste destruction, off-gas treatment, final forms, and process monitoring/control. MWIP is expediting the development of a suite of technologies to process heterogeneous waste. One robust process is the fixed-hearth plasma-arc process that is being developed to treat a wide variety of contaminated materials with minimal characterization. Additional processes include steam reforming and a catalytic extraction process that uses molten metal technology. Both processes are being demonstrated by the commercial developer of the technology. Advanced off-gas systems are also being developed. Vitrification technologies are being demonstrated for the treatment of homogeneous wastes such as incinerator ash and sludge. An alternative to conventional evaporation for liquid removal-freeze crystallization-is being investigated. Since mercury is present in numerous waste streams, mercury-removal technologies are being developed.

Engineering research, development and technology report  

Energy Technology Data Exchange (ETDEWEB)

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.
