International Nuclear Information System (INIS)

Japan Atomic Energy Agency (JAEA) has been implementing the 'Fast Reactor Cycle Technology Development (FaCT)' project in cooperation with electric utilities toward the commercialization of fast reactor cycle system in Japan before 2050. In the FaCT project, a combination system of 'the Japan Sodium-cooled Fast Reactor (JSFR) with oxide fuel, the advanced aqueous reprocessing, and the simplified pelletizing fuel fabrication' has been adopted pursuing full-actinides recycling in a closed cycle. In the advanced aqueous reprocessing concept, JAEA has proposed NEXT (New extraction system for TRU recovery) system consists of six innovative technologies (disassembling and shearing, fuel dissolution, uranium (U) crystallization, highly effective extraction system with group separation of U- plutonium (Pu) - neptunium (Np), MA recovery by extraction chromatography and Salt-free process for waste reduction ). Toward the present milestone in the FaCT project, the evaluation work to decide whether the innovative technologies can be adopted for the advanced aqueous reprocessing is in progress. So far, on the basis of the progress in design study and research works on the relevant innovative technologies, three technologies as disassembling/shearing, highly effective dissolution and effective uranium pre-recovery by crystallization are judged to be adoptable in the preliminary assessment by JAEA and electric utilities. The final decision will be made by the end of 2010. The selectill be made by the end of 2010. The selected technologies will be adopted for the conceptual design, and related research and development works will be carried out from 2011, and the future development program toward the commercialization until 2015 would be applied.

Predominant achievements of fuel cycle technology development in the FaCT project  

International Nuclear Information System (INIS)

JAEA has been conducting the FaCT project. In the FaCT project, the integration of the sodium-cooled fast reactor with oxide fuel, the NEXT process for reprocessing and the simplified pelletizing method for fuel fabrication was selected as the candidate of main concept, because it was thought to be the most promising concept for commercialization. For the NEXT process and the simplified pelletizing fuel fabrication, 12 tasks of innovative technologies have been identified to be developed target in the FaCT project. Through the R and D program so far, several tasks which were broken down as innovative technologies for each NEXT process and simplified fuel fabrication process were prospective for new type of fuel cycle concept. Design study of a commercial plant of FBR, fuel reprocessing, and fuel fabrication with the capacity of 200tHM/y has been made to provide a concept of future plant assuming to apply these innovative technologies. An evaluation for the construction cost shows that the equipment cost of innovative technologies is small and the construction cost of reprocessing plant depends on the any other equipment (foundation, maintenance, utilities, waste treatment etc.). As for the fuel fabrication plant, the amount for maintenance facility is large because of the necessity to place the maintenance cell, being equipped indispensable handling instruments in it.

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.

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

International Nuclear Information System (INIS)

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

Current status on fuel cycle system of fast reactor cycle technology development (FaCT) project in Japan  

International Nuclear Information System (INIS)

The integration of the advanced aqueous reprocessing system and the simplified pelletizing fuel fabrication (MOX fuel) was selected as the most promising fuel cycle system and have been developed as the FaCT project in Japan. Six R and D issues for reprocessing are identified. Crystallization is the one of the major technologies to recover a large amount of uranium from the solution. The residual solution is loaded to the extraction process for U, Pu and Np co-recovery. Raffinate solution from the extraction process contains FP and MA, where MA is extracted by chromatography. These processes are expected to be more efficient in costs, wastes management, and the nuclear non-proliferation. As for fuel fabrication technology, six R and D issues are identified. The source powder preparation technology of the conversion and granulation process is the most essential development issues for the simplified pelletizing method. Remote operation and remote maintenance technology is essential to handle the low decontaminated TRU fuel in a hot cell. Influence upon the quality assurance and countermeasure of heat generation by MA bearing is evaluated. Various investigation, laboratory scale hot tests, semi-engineering scale tests (cold and/or uranium), conceptual design study etc. are still going on as the FaCT project. Current R and D status and plan of this integrated system until around 2015 is reported. (author)

Oxide fuel fabrication technology development of the FaCT project (3). Analysis of sintering behavior for MOX pellet production  

International Nuclear Information System (INIS)

Sintering experiments of MOX pellets were carried out in various heat treatments, and the shrinkage behavior and O/M changes were investigated with a dilatometer and thermo-gravimeter. The specimen of the MOX pellets were obtained from MOX powder of 20% and 30% Pu contents which were prepared from the microwave heating method. A master sintering curve was derived from the shrinkage curve of the MOX, from which the activation energy of the MOX pellet was obtained to be 420 kJ/mol. The O/M changes of MOX pellets were measured as a function of partial pressures, PH2/PH2O. The O/M decreased with increasing PH2/PH2O. Then the O/M changes were evaluated as functions of heat treatment conditions and PH2/PH2O ratio in the atmosphere. The experimental results of the shrinkage rate and the O/M change will be used to accurately control shrinkage behavior and contribute to the development of the advanced pellet production process.

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

International Nuclear Information System (INIS)

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

Wind turbines - facts from 20 years of technological progress  

International Nuclear Information System (INIS)

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)

String Theory: Basic Facts and Recent Developments  

International Nuclear Information System (INIS)

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

Wind energy technology developments  

DEFF Research Database (Denmark)

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

Stirling technology development status  

Science.gov (United States)

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.

Marine & hydrokinetic technology development.  

Energy Technology Data Exchange (ETDEWEB)

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

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.

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

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.

Graphite Technology Development Plan  

Energy Technology Data Exchange (ETDEWEB)

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

ECH Technology Development  

Energy Technology Data Exchange (ETDEWEB)

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

Transmutation Technology Development  

Energy Technology Data Exchange (ETDEWEB)

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.

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)

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

Graphite Technology Development Plan  

Energy Technology Data Exchange (ETDEWEB)

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

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

DEFF Research Database (Denmark)

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

Development of sodium technology  

International Nuclear Information System (INIS)

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, ?c = ?·g-0.83·10(3570/TNa-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

Key technological challenges for JSFR development  

International Nuclear Information System (INIS)

JSFR is a sodium cooled loop type fast reactor on which a conceptual design study is now underway in the framework of 'Fast Reactor Cycle Technology Development Project (FaCT project)' of Japan. Achieving economic competitiveness with future light water reactors, along with assuring high level of safety and reliability, is among the most crucial development targets. A number of innovative technologies are pursued for these purposes. A two loop primary heat transfer system (PHTS) design, integration of a main circulation pump and an intermediate heat exchanger (IHX) into one single component, and adoption of high chrome ferritic steel as a structural material are typical technologies mainly for economic purposes. A passive shutdown system, decay heat removal by natural convection, and re-criticality free core configuration are those for mainly safety enhancement purposes. Technically challenging issues inevitably accompany these innovative technologies, and a systematic research and development program is undertaken for resolving these issues and realization of the plant design. An overall picture will be given in this paper on the design concept of JSFR that will be followed by descriptions on the major innovative technologies and their relevant research and development activities.

Progress on reactor system technology in the FaCT project toward the commercialization of fast reactor cycle system  

International Nuclear Information System (INIS)

Japan Atomic Energy Agency (JAEA) is now carrying out the 'Fast Reactor Cycle Technology Development (FaCT)' project toward the commercialization of fast reactor (FR) cycle system. The design targets including 'Safety and Reliability', 'Sustainability', 'Economic Competitiveness' and 'Nuclear Non-proliferation' have been established as the principle of specifications for FR cycle technology at the deployment stage around 2050, to contribute to the global needs which the 21st century has encountered more than ever before, such as the environmental protection and the remarkable increase of energy demand foreseen especially in developing countries. In accordance with those design targets, the design study and the related research and development (R and D) on innovative technologies for Japan Sodium-cooled Fast Reactor (JSFR) have been in progress aiming at the completion of the conceptual design stage by 2015. The demonstration reactor is planned to operate around 2025. An interim report is ready for issue in June 2009. The report will show the design specifications considered to be feasible at present to meet the requirements for the commercialization and the R and D results to support the feasibility, as well as the investigation on optional measures to take for some of the innovative technologies which may have several high technical hurdles to be realized.

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.

Innovative developments in sand reclamation technologies  

Directory of Open Access Journals (Sweden)

Full Text Available Proper sand management and efficient sand reclamation system are two main factors influencing economical and ecological side of modern foundry plant. It is well known fact that the production of 1 metric ton of casting from ferrous alloys generates circa 1 metric ton of waste [1], which due to containing certain amounts of harmful and dangerous compounds should undergo a reclamation – at least of the main component, which means a silica sand grains. The paper present problems of scientific and development research concerning the innovative reclamation technologies of used foundry sands such as: mechanical-cryogenic reclamation and innovative thermal reclamation.

Progress on reactor system technology in the FaCT project toward the commercialization of fast reactor cycle system  

International Nuclear Information System (INIS)

Japan Atomic Energy Agency (JAEA) is now carrying out 'Fast Reactor Cycle Technology Development (FaCT)' project along with the approach to the commercialization of fast reactor (FR) cycle system. The design targets including 'Safety and Reliability', 'Sustainability', 'Economic Competitiveness' and 'Nuclear Non-proliferation' have been established as the principle of specifications for fast reactor cycle technology at the deployment stage around 2050, to contribute to meeting the global needs which the 21st century has encountered more than ever before, such as the environmental protection and the remarkable increase of energy demand foreseen especially in developing countries. In accordance with those design targets, design study and the related research and development (R and D) on innovative technologies for Japan Sodium-cooled Fast Reactor (JSFR) have been in progress aiming at completion of the conceptual design stage by 2015. The demonstration reactor is planned to operate around 2025. An interim report is ready for issue in June, 2009 which will show the design specifications considered to be feasible at present to meet the requirements for the commercialization and the R and D results to support the feasibility, as well as the investigation on optional measures to take for some of the innovative technologies which may have a high technical hurdle to be realized. A council was coordinated by five parties; Ministry of Education, Culture, Sports, Science and Tecducation, Culture, Sports, Science and Technology (MEXT), Ministry of Economy, Trade and Industries (METI), electric utilities, vendors and JAEA to discuss and conduct the R and D schedule and path forward for demonstration of the FR cycle technologies. New advanced R and D bodies have been also structured in JAEA, i.e., Fast Breeder Reactor Plant Engineering Research Center in Tsuruga as a center of excellence for key FR technologies such as inspection and repair on the basis of operation experience of Monju, and a sodium component test facility in Oarai to develop and demonstrate the function of the components and cooling systems. An international collaboration is emphasized as an effective accelerating force for FaCT, as the development of FR cycle technology actually needs a long-term effort and large resources. Generation-IV International Forum (GIF) is a representative multilateral collaboration framework where Japan has participated since the initial stage of GIF and actively cooperated on especially sodium-cooled FR system as a leading role in its development. Actually, the design targets for FaCT and those for GIF were provided so as to be consistent with each other. International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) is also a multilateral collaboration framework where the assessment study on the JSFR concept has been implemented through the INPRO assessment method. Continuous challenge toward the commercialization of FR cycle system will be made by utilizing the design and R and D results as resources for the key milestone in JFY2010 to determine which innovative technologies should be adopted, together with preliminary conceptual design study results for the demonstration reactor

Development and foreign debt: The stylized facts 1970-2006  

DEFF Research Database (Denmark)

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

Multichip module technology development  

International Nuclear Information System (INIS)

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

Value of technology for development  

International Nuclear Information System (INIS)

We are gathered here for the purpose of sharing our experiences, working together and helping each other in order to chart a course of direction to more effectively utilize nuclear energy for sustainable development, while ensuring that it is used by authorized institutions worldwide. We believe that increased, but proper, use of this energy resource is bound to lead to a more prosperous, peaceful and secure world. At first glance it would seem out of place to dwell upon a rather broad theme, Value of Technology for Development, during a conference dedicated to the issues of security against abuse of nuclear technology. However, it makes good sense to recount the enormous benefits which demand continued use of this technology in spite of a myriad of concerns. Many of the concerns mentioned earlier are important. As such these concerns need to be addressed effectively - the earlier the better. However, we need to chalk out strategies for averting the risks associated with the widespread use of nuclear technology as well as encourage the utilization of this bounty of nature for accelerated development of the poor countries. I will limit my submissions to nuclear technology only. However, there are other technologies, such as biotechnology and information technology, which are expected to transform the patterns of development in a fundamental way in the coming decades. While limiting the scope of my presentation in this sense, I would like to make an essential addition twould like to make an essential addition to the requirement of development by emphasizing its sustainability. It is all too important that present needs are met without compromising the ability of future generations to meet their needs. In my view, the development of nuclear technology becomes necessary when viewed in terms of its impact on a longer time scale

Pyroprocessing technology development at KAERI  

International Nuclear Information System (INIS)

Pyroprocessing technology was developed in the beginning for metal fuel treatment in the US in the 1960s. The conventional aqueous process, such as PUREX, is not appropriate for treating metal fuel. Pyroprocessing technology has advantages over the aqueous process: less proliferation risk, treatment of spent fuel with relatively high heat and radioactivity, compact equipment, etc. The addition of an oxide reduction process to the pyroprocessing metal fuel treatment enables handling of oxide spent fuel, which draws a potential option for the management of spent fuel from the PWR. In this context, KAERI has been developing pyroprocessing technology to handle the oxide spent fuel since the 1990s. This paper describes the current status of pyroprocessing technology development at KAERI from the head-end process to the waste treatment. A unit process with various scales has been tested to produce the design data associated with the scale up. A performance test of unit processes integration will be conducted at the PRIDE facility, which will be constructed by early 2012. The PRIDE facility incorporates the unit processes all together in a cell with an Ar environment. The purpose of PRIDE is to test the processes for unit process performance, operability by remote equipment, the integrity of the unit processes, process monitoring, Ar environment system operation, and safeguards related activities. The test of PRIDE will be promising for further pyroprocessing technology devefor further pyroprocessing technology development

Development of FR construction cost estimation method in FaCT project  

International Nuclear Information System (INIS)

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

Advanced Mirror & Modelling Technology Development  

Science.gov (United States)

The 2020 Decadal technology survey is starting in 2018. Technology on the shelf at that time will help guide selection to future low risk and low cost missions. The Advanced Mirror Technology Development (AMTD) team has identified development priorities based on science goals and engineering requirements for Ultraviolet Optical near-Infrared (UVOIR) missions in order to contribute to the selection process. One key development identified was lightweight mirror fabrication and testing. A monolithic, stacked, deep core mirror was fused and replicated twice to achieve the desired radius of curvature. It was subsequently successfully polished and tested. A recently awarded second phase to the AMTD project will develop larger mirrors to demonstrate the lateral scaling of the deep core mirror technology. Another key development was rapid modeling for the mirror. One model focused on generating optical and structural model results in minutes instead of months. Many variables could be accounted for regarding the core, face plate and back structure details. A portion of a spacecraft model was also developed. The spacecraft model incorporated direct integration to transform optical path difference to Point Spread Function (PSF) and between PSF to modulation transfer function. The second phase to the project will take the results of the rapid mirror modeler and integrate them into the rapid spacecraft modeler.

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.''

Next stages in HDR technology development  

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.

competitive technologies for sustainable development  

International Nuclear Information System (INIS)

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

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.

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

Technology trade in economic development  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

The detrimental effect of interference in multiplication facts storing: Typical development and individual differences.  

Science.gov (United States)

The difficulty in memorizing arithmetic facts is a general and persistent hallmark of math learning disabilities. It has recently been suggested that hypersensitivity to interference could prevent a person from storing arithmetic facts. The similarity between arithmetic facts would provoke interference, and learners who are hypersensitive to interference would therefore encounter difficulties in storing arithmetic facts in long-term memory. In this study, we created a measure of the interference weight for each multiplication by measuring the overlap of digits between multiplications. First, we tested whether the interference parameter could predict performance across multiplications by analyzing the data from undergraduates published by Campbell (1997). The interference parameter substantially predicted performance across multiplications. Similarly, the performance across multiplications was substantially determined by the interference parameter in 3rd-grade children, 5th-grade children, and undergraduates we tested. Second, we tested whether people with poor arithmetic facts abilities were particularly sensitive to the interference parameter. We tested this hypothesis in typical development by analyzing the data from the 3rd-grade children, 5th-grade children, and undergraduates. We analyzed data with regard to atypical development from a published case study of dyscalculia as well as from 4th-grade children, with either poor or good multiplication skills, tested twice 1 year apart. Results showed that the individual sensitivity to the interference parameter determined part of the individual differences in multiplication performance in all data sets. These findings show that the learning of multiplications is particularly interference prone because of feature overlap and that people who are sensitive to this parameter therefore encounter difficulties in memorizing arithmetic facts.

Technology development in market networks  

International Nuclear Information System (INIS)

Technology procurement is used as an environmental control means in Sweden to promote the manufacturing and sale of energy-efficient technologies. The public authority in charge makes use of the market mechanism in alternating co-operative and competitive elements. The fragmented market, with its standardised products for many small customers, is brought together to specify desired product developments. These demands also include other qualities besides energy efficiency. A contest is announced in which a possible future market is indicated to manufacturers. Efforts are made to enlarge the market to motivate their investment and to keep down the unit cost. Each side in the deal is thus given an incentive to act in the desired direction. (author)

Protection of civil rights and technological development  

International Nuclear Information System (INIS)

The question of how the consequences of technological development are to be mastered on the legal level is not primarily a problem of the administrative procedure. The essential point in the discussion on protection of basic rights is not to be seen in the citizen's right to participate in administrative procedures, but rather in the substantive civil rights of individual persons as against the government, together with the system of values established in the Basic Law and derived from the basic rights, as well as in the proper functioning of the principle of separation of powers (legislature, administration, and judicature). The law on procedure and thus the idea of (protection of civil rights by rules of procedure) in this context only have an enhancing effect. Practical protection of civil rights is also ascertained in the Federal Republic of Germany by the particularly well-established guarantee of access to the courts. Another idea to be mentioned in this context is an approach that can be termed as 'protection of civil rights by government-funded research'. Other facts contributing to building a protective shield against infringement of civil rights by technology, activities or installations, include e.g. the federal structure of the state and the administration, type and scope of organisation of the public service, the established system of environmental protection and the safety provided by the current system of expert opinions.

Development of nuclear analytical technology  

International Nuclear Information System (INIS)

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

The Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) is funding a program to consolidate commercial spent fuel for testing in dry storage casks and to develop technology that will be fed into other OCRWM programs, e.g., Prototypical Consolidation Demonstration Program (PCDP). The program is being conducted at the Idaho National Engineering Laboratory (INEL) by the INEL Operating Contractor EG and G Idaho, Inc. Hardware and software have been designed and fabricated for installation in a hot cell adjacent to the Test Area North (TAN) Hot Shop Facility. This equipment is used to perform dry consolidation of commercial spent fuel from the Virginia Power (VP) Cooperative Agreement Spent Fuel Storage Cask (SFSC) Demonstration Program and assemblies that had previously been stored at the Engine Maintenance and Disassembly (EMAD) facility in Nevada. Consolidation is accomplished by individual, horizontal rod pulling. A computerized semiautomatic control system with operator involvement is utilized to conduct consolidation operations. During consolidation operations, data is taken to characterize this technology. Still photo, video tape, and other documentation will be generated to make developed information available to interested parties. Cold checkout of the hardware and software was completed in September of 1986. Following installation in the hot cell, consolidation operations begins in May 1987. Resulting consolidated fuel will be uti7. Resulting consolidated fuel will be utilized in the VP Cooperative Agreement SFSC Program

Research and Development Policy on FBR Cycle Technology in Japan  

International Nuclear Information System (INIS)

The fast breeder reactor (FBR) is a quite effective and realistic measure for establishing a long term, stable energy supply and for preventing global warming. In Japan, the FBR research and development project, named FBR Cycle Technology Development (FaCT), has been operational since April 2006. In this project, the combination of a sodium cooled fast reactor using oxide fuel and advanced aqueous reprocessing, as well as the simplified pelletizing fuel fabrication, is being developed principally as the most promising concept of FBR cycle technology to be commercialized, aiming at introducing the demonstration FBR by around 2025, and the commercial FBR before approximately 2050. Research and development for the establishment of the innovative technologies, which can meet design requirements for the demonstration FBR, has been steadily progressing. The adoption of the innovative technologies will be decided by judging their applicability and the conceptual designs of demonstration and commercial FBR cycle facilities by 2015. Consequently, the development of innovative technologies should be completed by 2015. Thereafter, the FaCT project will enter the introduction stage through a system demonstration. (author)

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)

Decontamination and restoration technology development  

International Nuclear Information System (INIS)

This study is to develop a chemical decontamination technology applicable in a high radiation field such as spent fuel decontamination. A new decontamination formulation was developed in this study by adding ascorbic acid into the existing KAERI chemicals mainly consisting of EDTA and citric acid showed remarkable improvement in dissolution rate of nickel ferrite particles which were hard to be removed by conventional chemical decontamination reagents. The decontamination process development using the reagent was also carried out in this study. The hot loop decontamination tests using the specimens of Inconel-600 and SUS-304 contacted with the pressure boundary of primary coolant in Kori Unit 1 showed high decontamination factors which is as good as or even better than those of foreign processes such as LOMI and CAN-DECON. The decontamination test using spent fuel rod in Kori Unit 1 resulted in almost complete removal of crud from the rod surface. The material damages measured by corrosion surveilance specimen were very small and no localized corrosion were detected. The catalytic wet oxidation behaviors were also studied to decompose decontamination wastes. The Fe(II) catalyst was found to be effective. (Author)

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.

Cooperative technology development: An approach to advancing energy technology  

International Nuclear Information System (INIS)

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

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.

Managing Innovation and Technology in Developing Countries  

CERN Document Server

Innovation and technology management is an inevitable issue in the high end technological and innovative organizations. Today, most of the innovations are limited with developed countries like USA, Japan and Europe while developing countries are still behind in the field of innovation and management of technology. But it is also becoming a subject for rapid progress and development in developing countries. Innovation and technology environment in developing countries are by nature, problematic, characterized by poor business models, political instability and governance conditions, low education level and lack of world-class research universities, an underdeveloped and mediocre physical infrastructure, and lack of solid technology based on trained human resources. This paper provides a theoretical and conceptual framework analysis for managing innovation and technology in developing countries like India and China. We present the issues and challenges in innovation and technology management and come up with pro...

Development of Coated Particle Fuel Technology  

International Nuclear Information System (INIS)

Uranium kernel fabrication technology using a wet chemical so-gel method, a key technology in the coated particle fuel area, is established up to the calcination step and the first sintering of UO2 kernel was attempted. Experiments on the parametric study of the coating process using the surrogate ZrO2 kernel give the optimum conditions for the PyC and SiC coating layer and ZrC coating conditions were obtained for the vaporization of the ZrCl4 precursor and coating condition from ZrC coating experiments using plate-type graphite substrate. In addition, by development of fuel performance analysis code a part of the code system is completed which enables the participation to the benchmark calculation and comparison in the IAEA collaborated research program. The technologies for irradiation and post irradiation examination, which are important in developing the HTGR fuel technology of its first kind in Korea was started to develop and, through a feasibility study and preliminary analysis, the technologies required to be developed are identified for further development as well as the QC-related basic technologies are reviewed, analyzed and identified for the own technology development. Development of kernel fabrication technology can be enhanced for the remaining sintering technology and completed based on the technologies developed in this phase. In the coating technology, the optimum conditions obtained using a surrogate ZrO2 kernel material can be applied for the uranium kernel coating process development. Also, after completion of the code development in the next phase, more extended participation to the international collaboration for benchmark calculation can be anticipated which will enable an improvement of the whole code system. Technology development started in this phase will be more extended and further focused on the detailed technology development to be required for the related technology establishment

Environmental technology applications: fact file on toxic contaminants in industrial waste process streams  

Energy Technology Data Exchange (ETDEWEB)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

Lunar Surface Systems Supportability Technology Development Roadmap  

Science.gov (United States)

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

Learning in renewable energy technology development  

International Nuclear Information System (INIS)

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

Technology development for radiation shielding analysis  

International Nuclear Information System (INIS)

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

Technology transfer in the Clean Development Mechanism  

International Nuclear Information System (INIS)

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

Technology Development Roadmaps - a Systematic Approach to Maturing Needed Technologies  

Energy Technology Data Exchange (ETDEWEB)

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

Microhole Drilling Tractor Technology Development  

Energy Technology Data Exchange (ETDEWEB)

In an effort to increase the U.S. energy reserves and lower costs for finding and retrieving oil, the USDOE created a solicitation to encourage industry to focus on means to operate in small diameter well-Microhole. Partially in response to this solicitation and because Western Well Tool's (WWT) corporate objective to develop small diameter coiled tubing drilling tractor, WWT responded to and was awarded a contract to design, prototype, shop test, and field demonstrate a Microhole Drilling Tractor (MDT). The benefit to the oil industry and the US consumer from the project is that with the MDT's ability to facilitate Coiled Tubing drilled wells to be 1000-3000 feet longer horizontally, US brown fields can be more efficiently exploited resulting in fewer wells, less environmental impact, greater and faster oil recovery, and lower drilling costs. Shortly after award of the contract, WWT was approached by a major oil company that strongly indicated that the specified size of a tractor of 3.0 inches diameter was inappropriate and that immediate applications for a 3.38-inch diameter tractor would substantially increase the usefulness of the tool to the oil industry. Based on this along with an understanding with the oil company to use the tractor in multiple field applications, WWT applied for and was granted a no-cost change-of-scope contract amendment to design, manufacture, assemble, shop test and field demonstrate a prototype a 3.38 inch diameter MDT. Utilizing existing WWT tractor technology and conforming to an industry developed specification for the tool, the Microhole Drilling Tractor was designed. Specific features of the MDT that increase it usefulness are: (1) Operation on differential pressure of the drilling fluid, (2) On-Off Capability, (3) Patented unique gripping elements (4) High strength and flexibility, (5) Compatibility to existing Coiled Tubing drilling equipment and operations. The ability to power the MDT with drilling fluid results in a highly efficient tool that both delivers high level of force for the pressure available and inherently increases downhole reliability because parts are less subject to contamination. The On-Off feature is essential to drilling to allow the Driller to turn off the tractor and pull back while circulating in cleanout runs that keep the hole clean of drilling debris. The gripping elements have wide contact surfaces to the formation to allow high loads without damage to the formation. As part of the development materials evaluations were conducted to verify compatibility with anticipated drilling and well bore fluids. Experiments demonstrated that the materials of the tractor are essentially undamaged by exposure to typical drilling fluids used for horizontal coiled tubing drilling. The design for the MDT was completed, qualified vendors identified, parts procured, received, inspected, and a prototype was assembled. As part of the assembly process, WWT prepared Manufacturing instructions (MI) that detail the assembly process and identify quality assurance inspection points. Subsequent to assembly, functional tests were performed. Functional tests consisted of placing the MDT on jack stands, connecting a high pressure source to the tractor, and verifying On-Off functions, walking motion, and operation over a range of pressures. Next, the Shop Demonstration Test was performed. An existing WWT test fixture was modified to accommodate operation of the 3.38 inch diameter MDT. The fixture simulated the tension applied to a tractor while walking (pulling) inside 4.0 inch diameter pipe. The MDT demonstrated: (1) On-off function, (2) Pulling forces proportional to available differential pressure up to 4000 lbs, (3) Walking speeds to 1100 ft/hour. A field Demonstration of the MDT was arranged with a major oil company operating in Alaska. A demonstration well with a Measured Depth of approximately 15,000 ft was selected; however because of problems with the well drilling was stopped before the planned MDT usage. Alternatively, functional and operational tests were run with th

Technology Development: From Idea to Implementation - 12131  

International Nuclear Information System (INIS)

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

Technological competences: a conceptual basis for technological development in Colombia  

Directory of Open Access Journals (Sweden)

Full Text Available There are high levels of things unforeseen in the dynamics of supply and demand within the context of a changing economy, the- reby demanding that technological development requires high levels of efficiency offering pertinent solutions to social contexts and real market expectations. Technology is interpreted today from a broad perspective, involving hard and soft components. During the recent decade the specialised literature has emphasised that production apparatus development generally depends upon the latter. Aspects related to soft technology are not usually dealt with by academics and are practically ignored by the goods and services industry in countries having emergent economies. The present article proposes that technological competen- ce’s pertinence in production apparatus should be analysed, being involved as a key aspect of soft technology; a conceptual ba- se is thus initially reviewed and the topic’s development compared in different settings. The foregoing led to establishing the gaps between developed and emergent countries, in turn offering a basis for defining challenges in local contexts. Analysing the deve- lopment and impact of technological competence in the case of Colombia revealed the backward state of things, this being why recommendations are then made for promoting the topic.

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

International Nuclear Information System (INIS)

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

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

Development of High Temperature Gas Sensor Technology  

Science.gov (United States)

The measurement of engine emissions is important for their monitoring and control. However, the ability to measure these emissions in-situ is limited. We are developing a family of high temperature gas sensors which are intended to operate in harsh environments such as those in an engine. The development of these sensors is based on progress in two types of technology: (1) The development of SiC-based semiconductor technology; and (2) Improvements in micromachining and microfabrication technology. These technologies are being used to develop point-contact sensors to measure gases which are important in emission control especially hydrogen, hydrocarbons, nitrogen oxides, and oxygen. The purpose of this paper is to discuss the development of this point-contact sensor technology. The detection of each type of gas involves its own challenges in the fields of materials science and fabrication technology. Of particular importance is sensor sensitivity, selectivity, and stability in long-term, high temperature operation. An overview is presented of each sensor type with an evaluation of its stage of development. It is concluded that this technology has significant potential for use in engine applications but further development is necessary.

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

International Nuclear Information System (INIS)

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 develo 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)

Clean coal technology development in China  

International Nuclear Information System (INIS)

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

Development of Nuclear Analytical Technology  

Energy Technology Data Exchange (ETDEWEB)

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

CROSSCUTTING TECHNOLOGY DEVELOPMENT AT THE CENTER FOR ADVANCED SEPARATION TECHNOLOGIES  

Energy Technology Data Exchange (ETDEWEB)

This Technical Progress Report describes progress made on the seventeen subprojects awarded in the first year of Cooperative Agreement DE-FC26-02NT41607: Crosscutting Technology Development at the Center for Advanced Separation Technologies. This work is summarized in the body of the main report: the individual sub-project Technical Progress Reports are attached as Appendices. Due to the time taken up by the solicitation/selection process, these cover the initial 6-month period of project activity only. 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. 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.

Development of the AP Technology Through Time  

Science.gov (United States)

This article presents the historical development of the AP Technology (Aluval, Voreppe, France) pot series starting with the AP13 in the 1960s, followed by the AP18 and the AP30 in the 1980s and 1990s. For most of the modern-era technology, from the late 1970s on, development has been based on a three-stage pattern, the first one being the pot modeling, followed by the pot prototype stage, and then the industrial stage, which fully validated the technology. This development pattern has proven to be successful since it has led to the very robust AP Technology pot design generation and a large number of greenfield smelters built in the 1990-2010 selected the AP Technology design. AP60 is the latest of this series: The development at the prototype level was initiated in the 1990s and is presented in the article. It is now followed by the first industrial realization at Jonquière with the startup in late 2013 and the full validation of the technology in mid-2014. The development of APXe, which aims at very low energy consumption, uses many common elements pertaining to the AP60 design and is presented in the article. AP Technology has also addressed the need for continuous and fast improvement of pot performances adapted to each existing client or site specifics; for this purpose, a new development methodology has recently emerged thanks to the very high modeling capabilities. This methodology, based on the validation of "technology bricks" and their integration in the final design following a strict process, is presented in the last section of this article.

Development of sludge dissolution technology  

International Nuclear Information System (INIS)

In the dissolution step of the PUREX process, sludge of zirconium molybdate can be generated from zirconium and molybdenum dissolved in the solution. In order to avoid accumulation of sludge, a cleaning method using a mixture of nitric acid and hydrogen peroxide has been developed. The cleaning method has been verified using an irradiated fuel. Cubic crystals of the zirconium molybdate ZrMo2O7(OH)2 were formed upon dissolution of an irradiated PWR fuel, and a small amount of fissile material was incorporated into the sludge. In order to recover the fissile material, the washing solution must be introduced into extraction process using TBP. Since there is no information on interaction between hydrogen peroxide and extraction reagents/equipments, it is necessary to decompose excess hydrogen peroxide before extraction. In this study, decomposition of hydrogen peroxide by catalytic reaction was tested. Sludge was then formed from an irradiated fuel, and was dissolved with a mixture of nitric acid and hydrogen peroxide. The excess hydrogen peroxide was well decomposed using platinum catalyst. From the solution, fissile material could be extracted by TBP with high distribution coefficient. (author)

Science and technology in a developing country: The Brazilian case  

International Nuclear Information System (INIS)

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

Development of FBR fuel cycle technology in Japan  

International Nuclear Information System (INIS)

Japan Atomic Energy Agency (JAEA) has been conducting the Fast Reactor Cycle Technology Development (FaCT) project. In the FaCT project, the integration of the sodium-cooled fast reactor with oxide fuel, the advanced aqueous reprocessing and the simplified pelletizing fuel fabrication was selected as the main concept, because it was the most promising concept for commercialization. Status of RandD for FBR fuel cycle technology. The reprocessing concept is constructed based on the well established aqueous reprocessing. Some innovative technologies are adopted for the aqueous reprocessing in order to realize MA recycle as well as economical competitiveness. U/Pu separation technology of the NEXT system has some options according to the specification of reprocessing fuels and products as shown in Fig. 1. These processes are expected to be more efficient in costs, wastes management, and the nuclear nonproliferation. Main task of the NEXT process is to develop the equipments in engineering-scale with high reliability, criticality safety, high durability and remote maintainability. On the other hand, for newly applied processes such as U crystallization and extraction chromatography for MAs, there is a wide range of RandD tasks from the basic chemistry to the development of the engineering-scale equipment. In the FaCT project, six items have been identified as the main issues to be developed corresponding to each process step. In the simplified palletizing method process, ie simplified palletizing method process, innovative technologies are adopted to rationalize pellet fabrication process. The plutonium content adjusting is performed by solution mixing of Pu and U nitrate. Therefore, lots of powder treatment process can be eliminated. 'Binder-less granulation process' and 'die wall lubrication pressing' bring elimination of processes of binder powder mixing, de-waxing and de-gassing. However, adoption of simplified extraction process and MA recovery process allows the reprocessing products, the source material for fuel fabrication, to contain some amount of FP and MA. Additional development issues were settled because high heat generation caused by decay heat of MA and high radio-activity of the fuel. Six main development issues are identified both for essential issues of the simplified pelletizing method process and for additional issues from MA and FP bearing. Main development issues for reprocessing and fuel fabrication technologies development are shown. Various investigation, laboratory scale hot tests, semi-engineering scale tests (cold and/or uranium), conceptual design study etc. are still going on. In 2008, JAEA has summarized current status of these development and rechecked the R and D deployment achieving goal targets at a check and review in 2010. These innovative technologies are decided to be adopted or not in 2010, on schedule. Furthermore, middle to long term R and D deployment has been under discussion considering urgent matters such as how to cope with the transition from LWR cycle to FBR cycle, fuel supply for the demonstration reactor etc. Investigation on Transition from LWR cycle to FBR cycle In Japan, the discussion of the next reprocessing plant, which will be operated from around 2050, will be started in the Japan Atomic Energy Commission from around 2010 as mentioned in 'Framework for Nuclear Energy Policy' (Oct. 2005). Considering the transition from LWR cycle to FBR cycle,the LWR UO2 SF and also LWR MOX SF, FBR SF would have to be reprocessed in the next reprocessing plant reasonably from the viewpoint of supply-demand balance of Pu and supply of the enough Pu products to FBR. The preliminary study and examination for transition from LWR cycle to FBR cycle has been conducted in cooperation with the related parties in Japan. The current results are the followings. 1) The necessity of the further examination for future nuclear power and fuel cycle deployment was identified, including investigation on transition of isotopic composition of nuclear materials. 2) The necessity to conduct the next reproc

International Nuclear Information System (INIS)

Fusion research in the world has nowadays been focused on the R and D of future fusion reactor technologies, such as technologies of large scale superconducting magnets, RF/NBI heating and current drive, blanket and divertor, plasma control and diagnostics, tritium recycling and radiation resistant materials. Some key technologies have been developed by the projects of HT-7 in operation and EAST being built in the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The technologies, such as long pulse discharges for plasma initiation with low loop voltage, wall conditioning, plasma facing material (PFM), non-inductive current drive and heating, plasma control and data acquisition and processing etc., have been developed very well on the HT-7 superconducting tokamak in the past five years. The R and D programs of EAST have been quite successful, which have been especially focusing on the superconducting technologies development, such as design, fabrication and test technologies of large scale magnets and cable-in-conduit conductor. A multi-element doped graphite and thick gradient SiC coatings on carbon based materials (CBM) have been developed as plasma facing materials of the EAST device. Detailed investigation of the composition has been done. High-Z materials, e.g. Mo and W, and functionally graded materials for PFM have also been studied in China. As a primary candidate of structural materials of blanket, the Chinese version of the RAFM (Reduced Acti Chinese version of the RAFM (Reduced Activation Ferritic/Marntensitic) steels, e.g. CLAM (China Low Activation Ferritic-Martensitic) steel, are being developed in ASIPP.

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.

Development of technologies for utilizing geothermal energy  

Energy Technology Data Exchange (ETDEWEB)

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

AFCI Safeguards Enhancement Study: Technology Development Roadmap  

Energy Technology Data Exchange (ETDEWEB)

The Advanced Fuel Cycle Initiative (AFCI) Safeguards Campaign aims to develop safeguards technologies and processes that will significantly reduce the risk of proliferation in the U.S. nuclear fuel cycle of tomorrow. The Safeguards Enhancement Study was chartered with identifying promising research and development (R&D) directions over timescales both near-term and long-term, and under safeguards oversight both domestic and international. This technology development roadmap documents recognized gaps and needs in the safeguarding of nuclear fuel cycles, and outlines corresponding performance targets for each of those needs. Drawing on the collective expertise of technologists and user-representatives, a list of over 30 technologies that have the potential to meet those needs was developed, along with brief summaries of each candidate technology. Each summary describes the potential impact of that technology, key research questions to be addressed, and prospective development milestones that could lead to a definitive viability or performance assessment. Important programmatic linkages between U.S. agencies and offices are also described, reflecting the emergence of several safeguards R&D programs in the U.S. and the reinvigoration of nuclear fuel cycles across the globe.

ISO: international standards development for nuclear technology  

International Nuclear Information System (INIS)

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

Legal reactions to new technological developments  

International Nuclear Information System (INIS)

The further development of engineering and technology in general but especially the development of new techniques results in reactions in society. The legal order, which constitutes an important sector of society, reacts to the progress of development with an increase of the intensity of regulation, with organisation and institutionalisation of objective knowledge, with developments in liability for damages, and with the development of collective compensation systems for damages. The reactions of the legal order will probably run on the same four lines in the case of future developments. Nevertheless, prevention will increase in importance at the expense of merely repressive reaction - and rightly so. (orig.)

Furthermore, microholes offer an environment for improved substance measurement. The combination of deep microholes having diameters of 1-3/8 in. at their terminal depth and 7/8-in. diameter logging tools will comprise a very low cost alternative to currently available technology for deep subsurface characterization and monitoring.

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

International Nuclear Information System (INIS)

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

Development of industrial ion implantation technology  

International Nuclear Information System (INIS)

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

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. 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.

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

International Nuclear Information System (INIS)

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

Incorporating Geospatial Technology into Teacher Professional Development  

Science.gov (United States)

The need for students to think spatially and use geospatial technologies is becoming more critical as these tools and concepts are increasingly incorporated into a broad range of occupations and academic disciplines. Geospatial Teaching Across the Curriculum (Geo-STAC) is a collaborative program that provides high school teachers with mentored professional development workshops in geospatial thought and technology. The seminars, led by community college faculty, give high school teachers the ability to incorporate geospatial technology into coursework across the curriculum — in Science, Technology, Engineering, and Math (STEM) and non-STEM disciplines. Students participating in the hands-on lessons gain experience in web-based and desktop Geographic Information Systems (GIS). The goals of the workshop are for teachers to: (1) understand the importance of geospatial thinking; (2) learn how to employ geospatial thinking in each discipline; (3) learn about geospatial technologies; (4) develop a Web-based GIS lesson; and, (5) implement a Web-based GIS lesson. Additionally, Geo-STAC works with high school students so that they: (1) understand the importance of geospatial technologies and careers in future job markets; (2) learn how to use Web-based GIS to solve problems; and, (3) visit the community college GIS lab and experience using desktop GIS. Geo-STAC actively disseminates this collaborative model to colleges to community colleges and high schools across the country.

Carbon prices and incentives for technological development.  

Science.gov (United States)

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

In-core thermionic technology development program  

International Nuclear Information System (INIS)

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 boduction 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

Strategic alliances in engineering, technology and development  

International Nuclear Information System (INIS)

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

A Proposal to Develop Interactive Classification Technology  

Science.gov (United States)

Research for the first year was oriented towards: 1) the design of an interactive classification tool (ICT); and 2) the development of an appropriate theory of inference for use in ICT technology. The general objective was to develop a theory of classification that could accommodate a diverse array of objects, including events and their constituent objects. Throughout this report, the term "object" is to be interpreted in a broad sense to cover any kind of object, including living beings, non-living physical things, events, even ideas and concepts. The idea was to produce a theory that could serve as the uniting fabric of a base technology capable of being implemented in a variety of automated systems. The decision was made to employ two technologies under development by the principal investigator, namely, SMS (Symbolic Manipulation System) and SL (Symbolic Language) [see debessonet, 1991, for detailed descriptions of SMS and SL]. The plan was to enhance and modify these technologies for use in an ICT environment. As a means of giving focus and direction to the proposed research, the investigators decided to design an interactive, classificatory tool for use in building accessible knowledge bases for selected domains. Accordingly, the proposed research was divisible into tasks that included: 1) the design of technology for classifying domain objects and for building knowledge bases from the results automatically; 2) the development of a scheme of inference capable of drawing upon previously processed classificatory schemes and knowledge bases; and 3) the design of a query/ search module for accessing the knowledge bases built by the inclusive system. The interactive tool for classifying domain objects was to be designed initially for textual corpora with a view to having the technology eventually be used in robots to build sentential knowledge bases that would be supported by inference engines specially designed for the natural or man-made environments in which the robots would be called upon to operate.

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.

Technological Development in Carbon Sequestration at Petrobras  

Energy Technology Data Exchange (ETDEWEB)

Petrobras defined, in its mission, the intention to act in a safe and profitable way, with social and environmental responsibility. In its vision, the company decided to be an oil and energy company, taking into account climate change mitigation. These changes were partially caused, without the company's knowledge, for many years, by the burning of fossil fuels. Among many technologies available for this mitigation, carbon sequestration is the one that, in a short space of time, can avoid the collapse of earth's climate. In order to meet this carbon sequestration challenge, there has been established, at CENPES, three strategies for its technological development: (i) establishment of a Systemic Project for Carbon Sequestration within the scope of the Environmental Technology Program - PROAMB; (ii) creation of a Group of Carbon Sequestration Technologies for Climate Change Mitigation - formation of team and qualification program, which includes the realization of the International Seminar on Carbon Sequestration and Climate Change at Petrobras in October 2006; and (iii) Implementation of the Technological Network of Technologies for Climate Change Mitigation.

Accelerator technology for radiation processing: Recent development  

International Nuclear Information System (INIS)

The progress in accelerator technology development means not only the growing number of unit but also lower cost, compact size suitable to the production line, beam shaped equally to the process, reliability and other parameters which are important in radiation processing application. The computers for automatic control and parts like power switches, thyristors, thyratrons and new generation of microwave sources are the best examples of the technology transfer which allows to perfect accelerators constructions. Demands coming from growing fields of radiation processing technology implementation stimulate R and D process of accelerator technology. Direct, transformer type accelerators, single resonant cavity accelerators and powered by microwave sources linear accelerators have been found the most suitable for radiation processing. Although the present level of accelerator development can satisfy most of commercial requirements the reliability is the most important parameter which should be improved to meet industrial standards. It should be noticed that the progress in accelerator technology is not a quick process but can be easily noticed in longer time scale. New accelerators constructions can frequently offer better economic and technical characteristics but only long time operation can revile weak points of certain accelerator in specific industrial conditions.

Development of key Technologies for Nuclear Hydrogen  

International Nuclear Information System (INIS)

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

Technologies in support of CANDU development  

International Nuclear Information System (INIS)

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

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

Decommissioning Technology Development for Nuclear Research Facilities  

Energy Technology Data Exchange (ETDEWEB)

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 SOI pixel process technology  

Energy Technology Data Exchange (ETDEWEB)

A silicon-on-insulator (SOI) process for pixelated radiation detectors is developed. It is based on a 0.2 {mu}m CMOS fully depleted (FD-)SOI technology. The SOI wafer is composed of a thick, high-resistivity substrate for the sensing part and a thin Si layer for CMOS circuits. Two types of pixel detectors, one integration-type and the other counting-type, are developed and tested. We confirmed good sensitivity for light, charged particles and X-rays for these detectors. For further improvement on the performance of the pixel detector, we have introduced a new process technique called buried p-well (BPW) to suppress back gate effect. We are also developing vertical (3D) integration technology to achieve much higher density.

TECHNOLOGY DEVELOPMENT ON THE DUPIC SAFEGUARDS SYSTEM  

International Nuclear Information System (INIS)

A safeguards system has been developed since 1993 in the course of supporting a fuel cycle process to fabricate CANDU fuel with spent PWR fuel (known as Direct Use of PWR spent fuel In CANDU, DUPIC). The major safeguards technology involved here was to design and fabricate a neutron coincidence counting system for process accountability, and also an unattended continuous monitoring system in association with independent verification by the IAEA. This combined technology was to produce information of nuclear material content and to maintain knowledge of the continuity of nuclear material flow. In addition to hardware development, diagnosis software is being developed to assist data acquisition, data review, and data evaluation based on a neural network system on the IAEA C/S system

Trends in Wind Energy Technology Development  

DEFF Research Database (Denmark)

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

Technological developments in IGCC for carbon capture  

Energy Technology Data Exchange (ETDEWEB)

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

Modular, Reconfigurable, High-Energy Technology Development  

Science.gov (United States)

The Modular, Reconfigurable High-Energy (MRHE) Technology Demonstrator project was to have been a series of ground-based demonstrations to mature critical technologies needed for in-space assembly of a highpower high-voltage modular spacecraft in low Earth orbit, enabling the development of future modular solar-powered exploration cargo-transport vehicles and infrastructure. MRHE was a project in the High Energy Space Systems (HESS) Program, within NASA's Exploration Systems Research and Technology (ESR&T) Program. NASA participants included Marshall Space Flight Center (MSFC), the Jet Propulsion Laboratory (JPL), and Glenn Research Center (GRC). Contractor participants were the Boeing Phantom Works in Huntsville, AL, Lockheed Martin Advanced Technology Center in Palo Alto, CA, ENTECH, Inc. in Keller, TX, and the University of AL Huntsville (UAH). MRHE's technical objectives were to mature: (a) lightweight, efficient, high-voltage, radiation-resistant solar power generation (SPG) technologies; (b) innovative, lightweight, efficient thermal management systems; (c) efficient, 100kW-class, high-voltage power delivery systems from an SPG to an electric thruster system; (d) autonomous rendezvous and docking technology for in-space assembly of modular, reconfigurable spacecraft; (e) robotic assembly of modular space systems; and (f) modular, reconfigurable distributed avionics technologies. Maturation of these technologies was to be implemented through a series of increasingly-inclusive laboratory demonstrations that would have integrated and demonstrated two systems-of-systems: (a) the autonomous rendezvous and docking of modular spacecraft with deployable structures, robotic assembly, reconfiguration both during assembly and (b) the development and integration of an advanced thermal heat pipe and a high-voltage power delivery system with a representative lightweight high-voltage SPG array. In addition, an integrated simulation testbed would have been developed containing software models representing the technologies being matured in the laboratory demos. The testbed would have also included models for non-MRHE developed subsystems such as electric propulsion, so that end-to-end performance could have been assessed. This paper presents an overview of the MRHE Phase I activities at MSFC and its contractor partners. One of the major Phase I accomplishments is the assembly demonstration in the Lockheed Martin Advanced Technology Center (LMATC) Robot-Satellite facility, in which three robot-satellites successfully demonstrated rendezvous & docking, self-assembly, reconfiguration, adaptable GN&C, deployment, and interfaces between modules. Phase I technology maturation results from ENTECH include material recommendations for radiation hardened Stretched Lens Array (SLA) concentrator lenses, and a design concept and test results for a hi-voltage PV receiver. UAH's accomplishments include Supertube heatpipe test results, which support estimates of thermal conductivities at 30,000 times that of an equivalent silver rod. MSFC performed systems trades and developed a preliminary concept design for a 100kW-class modular reconfigurable solar electric propulsion transport vehicle, and Boeing Phantom Works in Huntsville performed assembly and rendezvous and docking trades. A concept animation video was produced by SAIC, wllich showed rendezvous and docking and SLA-square-rigger deployment in LEO.

Coal preparation technology to developing countries  

Energy Technology Data Exchange (ETDEWEB)

Japan is the world's biggest importer of coal. Coal imports reached 163 million tons in 2002. This is equivalent to roughly one fifth of the coal volume traded worldwide. While coal has a major environmental impact, coal is also an energy sources which offers the greatest stability of price and supply in all fossil fuels. It is therefore of paramount importance for the coal using member economies to use coal in a cleaner manner in the future. In this context, CCT especially pre-combustion CCT such as coal preparation technology has the greatest investment effect and is therefore of great importance as CCT. A clear strategy is needed that will promote the widest possible diffusion of this technology to a coal producing developing country for sustainable clean coal technology. The Japan Coal Energy Center has carried out projects implementing Japanese coal preparation technologies in several coal-producing developing countries in Asia. The article presents three case studies carried out on: deashing and desulfurizing high-sulfur coal at Jinjia coal mine in China; R & D of a waste water treatment system of slurries from the open-cut tailing pond at the Ombilin Colliery in West Sumatra; and improvement of clean coal yield by upgrading jigs and heavy media cyclone process of coal preparation plants of the Cua Ong Coal Preparation company in Viet Nam, and improvement of the fine coal recovery process, the settling pond, and the quality control systems. 4 refs., 5 figs., 4 photos.

EXCEDE technology development III: first vacuum tests  

Science.gov (United States)

This paper is the third in the series on the technology development for the EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) mission concept, which in 2011 was selected by NASA's Explorer program for technology development (Category III). EXCEDE is a 0.7m space telescope concept designed to achieve raw contrasts of 1e6 at an inner working angle of 1.2 l/D and 1e7 at 2 l/D and beyond. This will allow it to directly detect and spatially resolve low surface brightness circumstellar debris disks as well as image giant planets as close as in the habitable zones of their host stars. In addition to doing fundamental science on debris disks, EXCEDE will also serve as a technological and scientific precursor for any future exo-Earth imaging mission. EXCEDE uses a Starlight Suppression System (SSS) based on the PIAA coronagraph, enabling aggressive performance. Previously, we reported on the achievement of our first milestone (demonstration of EXCEDE IWA and contrast in monochromatic light) in air. In this presentation, we report on our continuing progress of developing the SSS for EXCEDE, and in particular (a) the reconfiguration of our system into a more flight-like layout, with an upstream deformable mirror and an inverse PIAA system, and (b) testing this system in a vacuum chamber, including IWA, contrast, and stability performance. Even though this technology development is primarily targeted towards EXCEDE, it is also germane to any exoplanet direct imaging space-based telescopes because of the many challenges common to different coronagraph architectures and mission requirements. This work was supported in part by the NASA Explorer program and Ames Research Center, University of Arizona, and Lockheed Martin SSC.

Research and development contributions to fusion technology  

International Nuclear Information System (INIS)

Nuclear fusion is a possibility ensuring, on a long-term basis, the continuity of energy supply, for nuclear fusion makes use of almost unlimited fuel resources. In nuclear fusion, roughly one order of magnitude of energy more is released per unit mass of fuel than in nuclear fission. Work on fusion technology is performed with the long-term objective in mind of a fusion power plant. The next steps to be taken in the development concept are the construction of a large experimental facility of the tokamak type (Iter) and a large plasma physics experiment of the stellarator line (W7-X). The technologies required for these two plants have been developed by and large. The components are currently being manufactured and tested as prototype models. Developing a suitable material for the nuclear components of a fusion power reactor will become the key issue, after the technological problems will have been solved step by step, on which the economic viability and the environmental compatibility of fusion reactors depend.

EXCEDE Technology Development III: First Vacuum Tests  

CERN Document Server

This paper is the third in the series on the technology development for the EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) mission concept, which in 2011 was selected by NASA's Explorer program for technology development (Category III). EXCEDE is a 0.7m space telescope concept designed to achieve raw contrasts of 1e6 at an inner working angle of 1.2 l/D and 1e7 at 2 l/D and beyond. This will allow it to directly detect and spatially resolve low surface brightness circumstellar debris disks as well as image giant planets as close as in the habitable zones of their host stars. In addition to doing fundamental science on debris disks, EXCEDE will also serve as a technological and scientific precursor for any future exo-Earth imaging mission. EXCEDE uses a Starlight Suppression System (SSS) based on the PIAA coronagraph, enabling aggressive performance. We report on our continuing progress of developing the SSS for EXCEDE, and in particular (a) the reconfiguration of our system into a more fli...

WRAP-RIB antenna technology development  

Science.gov (United States)

The wrap-rib deployable antenna concept development is based on a combination of hardware development and testing along with extensive supporting analysis. The proof-of-concept hardware models are large in size so they will address the same basic problems associated with the design fabrication, assembly and test as the full-scale systems which were selected to be 100 meters at the beginning of the program. The hardware evaluation program consists of functional performance tests, design verification tests and analytical model verification tests. Functional testing consists of kinematic deployment, mesh management and verification of mechanical packaging efficiencies. Design verification consists of rib contour precision measurement, rib cross-section variation evaluation, rib materials characterizations and manufacturing imperfections assessment. Analytical model verification and refinement include mesh stiffness measurement, rib static and dynamic testing, mass measurement, and rib cross-section characterization. This concept was considered for a number of potential applications that include mobile communications, VLBI, and aircraft surveillance. In fact, baseline system configurations were developed by JPL, using the appropriate wrap-rib antenna, for all three classes of applications.

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

International Nuclear Information System (INIS)

It is believed that it is easier for Korea to become self-reliant in PHWR technology than in PWR technology, mainly because of the lower design pressure and temperature and because of the simplicity, economy, flexibility of the fuel cycle in comparison with PWR systems. Even though one has no doubt about the safety and the economics of the PHWR's that are now being operated or constructed in Korea. It is necessary to develop the advanced design technology for even safer and more economical PHWR systems to overcome the ever growing international resistance to sharing of nuclear technology and to meet the even more stringent requirements for the future public acceptance of nuclear power. This study is to develop the more advance design technology compared to the existing one, especially in the field of reactor physics, safety systems and safety evaluation to realize the above requirements. 71 tabs., 147 figs., 143 refs.

Decommissioning technology development for research reactors  

International Nuclear Information System (INIS)

Although it is expected that the decommissioning of a nuclear power plant will happen since 2020, the need of partial decommissioning and decontamination for periodic inspection and life extension has been on an increasing trend and domestic market has gradually been extended. Therefore, in this project the decommissioning DB system on the KRR-1 and 2 was developed as establishing the information classification system of the research reactor dismantling and the structural design and optimization of the decommissioning DB system. Also in order to secure the reliability and safety about the dismantling process, the main dismantling simulation technology that can verify the dismantling process before their real dismantling work was developed. And also the underwater cutting equipment was developed to remove these stainless steel parts highly activated from the RSR. First, the its key technologies were developed and then the design, making, and capability analysis were performed. Finally the actual proof was achieved for applying the dismantling site. an automatic surface contamination measuring equipment was developed in order to get the sample automatically and measure the radiation/radioactivity

Development of spent fuel remote handling technology  

International Nuclear Information System (INIS)

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

Development of Reconstitution Technology for Surveillance Specimens  

International Nuclear Information System (INIS)

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

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.

Fission Surface Power Technology Development Update  

Science.gov (United States)

Power is a critical consideration in planning exploration of the surfaces of the Moon, Mars, and places beyond. Nuclear power is an important option, especially for locations in the solar system where sunlight is limited or environmental conditions are challenging (e.g., extreme cold, dust storms). NASA and the Department of Energy are maintaining the option for fission surface power for the Moon and Mars by developing and demonstrating technology for a fission surface power system. The Fission Surface Power Systems project has focused on subscale component and subsystem demonstrations to address the feasibility of a low-risk, low-cost approach to space nuclear power for surface missions. Laboratory demonstrations of the liquid metal pump, reactor control drum drive, power conversion, heat rejection, and power management and distribution technologies have validated that the fundamental characteristics and performance of these components and subsystems are consistent with a Fission Surface Power preliminary reference concept. In addition, subscale versions of a non-nuclear reactor simulator, using electric resistance heating in place of the reactor fuel, have been built and operated with liquid metal sodium-potassium and helium/xenon gas heat transfer loops, demonstrating the viability of establishing system-level performance and characteristics of fission surface power technologies without requiring a nuclear reactor. While some component and subsystem testing will continue through 2011 and beyond, the results to date provide sufficient confidence to proceed with system level technology readiness demonstration. To demonstrate the system level readiness of fission surface power in an operationally relevant environment (the primary goal of the Fission Surface Power Systems project), a full scale, 1/4 power Technology Demonstration Unit (TDU) is under development. The TDU will consist of a non-nuclear reactor simulator, a sodium-potassium heat transfer loop, a power conversion unit with electrical controls, and a heat rejection system with a multi-panel radiator assembly. Testing is planned at the Glenn Research Center Vacuum Facility 6 starting in 2012, with vacuum and liquid-nitrogen cold walls to provide simulation of operationally relevant environments. A nominal two-year test campaign is planned including a Phase 1 reactor simulator and power conversion test followed by a Phase 2 integrated system test with radiator panel heat rejection. The testing is expected to demonstrate the readiness and availability of fission surface power as a viable power system option for NASA's exploration needs. In addition to surface power, technology development work within this project is also directly applicable to in-space fission power and propulsion systems.

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

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.

Developments in distributed optical fiber detection technology  

Science.gov (United States)

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

Small Hydropower Research and Development Technology Project  

Energy Technology Data Exchange (ETDEWEB)

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

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.

Development and technology transfer of Haemophilus influenzae type b conjugate vaccines for developing countries.  

Science.gov (United States)

This paper describes the development of a Haemophilus influenzae type b (Hib) conjugate vaccine at the National Institute for Public Health and the Environment/Netherlands Vaccine Institute (RIVM/NVI, Bilthoven, The Netherlands), and the subsequent transfer of its production process to manufacturers in developing countries. In 1998, at the outset of the project, the majority of the world's children were not immunized against Hib because of the high price and limited supply of the conjugate vaccines, due partly to the fact that local manufacturers in developing countries did not master the Hib conjugate production technology. To address this problem, the RIVM/NVI has developed a robust Hib conjugate vaccine production process based on a proven model, and transferred this technology to several partners in India, Indonesia, Korea and China. As a result, emerging manufacturers in developing countries acquired modern technologies previously unavailable to them. This has in turn facilitated their approach to producing other conjugate vaccines. As an additional spin-off from the project, a World Health Organization (WHO) Hib quality control (QC) course was designed and conducted at the RIVM/NVI, resulting in an increased regulatory capacity for conjugate vaccines in developing countries at the National Regulatory Authority (NRA) level. For the local populations, this has translated into an increased and sustainable supply of affordable Hib conjugate-containing combination vaccines. During the course of this project, developing countries have demonstrated their ability to produce large quantities of high-quality modern vaccines after a successful transfer of the technology.

Stirling technology development at NASA GRC  

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

A Framework for Penetration of Information Communications Technology into Developing Countries for Manpower and Economic Development  

Directory of Open Access Journals (Sweden)

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

Recent developments in PET detector technology  

International Nuclear Information System (INIS)

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

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.

Petawatt Laser Data Analysis and Technology Development  

Energy Technology Data Exchange (ETDEWEB)

The Petawatt (PW) laser beam line at the LLNL Nova laser facility was unique in the world in supplying an order of magnitude higher power (1PW in pulses of 500 fs duration) than lasers elsewhere. Focused to intensities reaching 3 x l0{sup 20} Wcm{sup -2}, it opened up a new regime of experimental science where free electron energies in the light wave are strongly relativistic. After full operational capability of the PW beam-line was reached, close to 25% of the operation of the Nova facility was dedicated to PW shots for two years, prior to the shut down of Nova in May 1999. A wealth of novel scientific data was obtained and it motivated the primary objective of this June 1 to Oct. 1, 1999 LDRD, which was to complete systematic analysis of the PW laser data. This was done by the team, which had conducted the experiments working with associated experts in theoretical modeling of the complex physical phenomena. A second objective was to develop a key new technology of large area transmission gratings needed for the next step to higher energy PW laser development. This work was done by the team, which developed the reflective grating technology.

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.

Thin Film Technology Development for the Powersphere  

Science.gov (United States)

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

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)

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 special nuclear components  

International Nuclear Information System (INIS)

One of the attractive features of Candu Pressurised Heavy Water Reactor design which influenced the decision to make it the foundation of our nuclear power programme, is that its main components (calandria, end shields, coolant channel components) are relatively simple - in comparison with reactor pressure vessel and associated components of Boiling Water Reactors or Pressurised Water Reactors - and considered to be within the scope of manufacture of developing countries. Over the last two decades, India has been very successful in technology development in many important and critical areas. We are now about to launch the construction of the first 500 MWe PHWR project at Tarapur. In this context, this paper focuses attention on some of the aspects relating to self-reliance in design, engineering and manufacture of these special components as currently perceived.

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.

Development of Core Design Technology for LMR  

International Nuclear Information System (INIS)

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

Development of spent fuel remote handling technology  

Energy Technology Data Exchange (ETDEWEB)

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 UO{sub 2} pellet into U{sub 3}O{sub 8} 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.

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.

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%.

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.

Review: DNA Microarray Technology and Drug Development  

Directory of Open Access Journals (Sweden)

Full Text Available

On the contrary to slow and non specific traditional drug discovery methods, DNA microarray technology could
accelerate the identification of potential drugs for treating diseases like cancer, AIDS and provide fruitful results in
the drug discovery. The technique provides efficient automation and maximum flexibility to the researchers and
can test thousand compounds at a time. Scientists find DNA microarray useful in disease diagnosis, monitoring
desired and adverse outcomes of therapeutic interventions, as well as, in the selection, assessment and quality control
of the potential drugs. In the current scenario, where new pathogens are expected every year, DNA microarray
promises as an efficient technology to detect new organisms in a short time. Classification of carcinomas at the
molecular level and prediction of how various types of tumor respond to different therapeutic agents can be made
possible with the use of microarray analysis. Also, microarray technique can prove instrumental in personalized
medicines development by providing microarray data of a patient which could be used for identifying diseases,
treatment specific to individual and trailing disease prognosis. Microarray analysis could be beneficial in the area
of molecular medicines for analysis of genetic variations and functions of genes in normal individuals and diseased
conditions. The technique can give satisfactory results in single nucleotide polymorphism (SNP analysis and
pharmacogenomics studies. The challenges that arise with the technology are high degree of variability with data
obtained, frequent up gradation of methods and machines and lack of trained manpower. Despite this, DNA microarray
promises to be the next generation sequencer which could explain how organisms evolve and adapt looking
at the whole genome. In a nutshell, Microarray technology makes it possible for molecular biologists to analyze
simultaneously thousands of DNA samples and monitor their behavior patterns, which brings about a tremendous
improvement over the tedious "one gene per experiment” technology that prevailed previously.

Development of Safety Analysis Technology for LMR  

International Nuclear Information System (INIS)

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

User Interface Technology for Formal Specification Development  

Science.gov (United States)

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

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.

This report summarizes the results of a Small Business Innovative Research Phase II project to develop a modular, surface conforming respirator monitor to improve upon the manual survey techniques presently used by the nuclear industry. Research was performed with plastic scintillator and gas proportional modules in an effort to find the most conducive geometry for a surface conformal, position sensitive monitor. The respirator monitor prototype developed is a computer controlled, position-sensitive detection system employing 56 modular proportional counters mounted in molds conforming to the inner and outer surfaces of a commonly used respirator (Scott Model 801450-40). The molds are housed in separate enclosures and hinged to create a open-quotes waffle-ironclose quotes effect so that the closed monitor will simultaneously survey both surfaces of the respirator. The proportional counter prototype was also designed to incorporate Shonka Research Associates previously developed charge-division electronics. This research provided valuable experience into pixellated position sensitive detection systems. The technology developed can be adapted to other monitoring applications where there is a need for deployment of many traditional radiation detectors

Development of advanced LWR fuel pellet technology  

International Nuclear Information System (INIS)

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

Energy Technology Data Exchange (ETDEWEB)

As a subcontractor to General Motors (GM), Ames Laboratory provided the technical expertise and supplied experimental materials needed to assess the technology of high energy bonded permanent magnets that are injection or compression molded for use in the Advanced Electric Traction System motor. This support was a sustained (Phase 1: 6/07 to 3/08) engineering effort that builds on the research achievements of the primary FreedomCAR project at Ames Laboratory on development of high temperature magnet alloy particulate in both flake and spherical powder forms. Ames Lab also provide guidance and direction in selection of magnet materials and supported the fabrication of experimental magnet materials for development of injection molding and magnetization processes by Arnold Magnetics, another project partner. The work with Arnold Magnetics involved a close collaboration on particulate material design and processing to achieve enhanced particulate properties and magnetic performance in the resulting bonded magnets. The overall project direction was provided by GM Program Management and two design reviews were held at GM-ATC in Torrance, CA. Ames Lab utilized current expertise in magnet powder alloy design and processing, along with on-going research advances being achieved under the existing FreedomCAR Program project to help guide and direct work during Phase 1 for the Advanced Electric Traction System Technology Development Program. The technical tasks included review of previous GM and Arnold Magnets work and identification of improvements to the benchmark magnet material, Magnequench MQP-14-12. Other benchmark characteristics of the desired magnet material include 64% volumetric loading with PPS polymer and a recommended maximum use temperature of 200C. A collaborative relationship was maintained with Arnold Magnets on the specification and processing of the bonded magnet material required by GM-ATC.

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.

Development of hydrocephalus and classical hypothesis of cerebrospinal fluid hydrodynamics: facts and illusions.  

Science.gov (United States)

According to the classical hypothesis of the cerebrospinal fluid (CSF) hydrodynamics, CSF is produced inside the brain ventricles, than it circulates like a slow river toward the cortical subarachnoid space, and finally it is absorbed into the venous sinuses. Some pathological conditions, primarily hydrocephalus, have also been interpreted based on this hypothesis. The development of hydrocephalus is explained as an imbalance between CSF formation and absorption, where more CSF is formed than is absorbed, which results in an abnormal increase in the CSF volume inside the cranial CSF spaces. It is believed that the reason for the imbalance is the obstruction of the CSF pathways between the site of CSF formation and the site of its absorption, which diminishes or prevents CSF outflow from the cranium. In spite of the general acceptance of the classical hypothesis, there are a considerable number of experimental results that do not support such a hypothesis and the generally accepted pathophysiology of hydrocephalus. A recently proposed new working hypothesis suggests that osmotic and hydrostatic forces at the central nervous system microvessels are crucial for the regulation of interstial fluid and CSF volume which constitute a functional unit. Based on that hypothesis, the generally accepted mechanisms of hydrocephalus development are not plausible. Therefore, the recent understanding of the correlation between CSF physiology and the development of hydrocephalus has been thoroughly presented, analyzed and evaluated, and new insights into hydrocephalus etiopathology have been proposed, which are in accordance with the experimental data and the new working hypothesis.

Nuclear technology and the developing world  

International Nuclear Information System (INIS)

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

International Nuclear Information System (INIS)

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

Development of solid oxide fuel cell technology  

Energy Technology Data Exchange (ETDEWEB)

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).

New technological developments for ocean LIDAR biomonitoring  

Science.gov (United States)

A pump-and-probe (P&P) airborne LIDAR has been recently developed at NASA Goddard Space Flight Center. It provides remote measurement of phytoplankton photosynthetic variables along with pigment and organic matter fluorescence, down-welling and upwelling hyperspectral measurements and sea surface temperature. The utilization of an airborne platform provides for rapid remote characterization of phytoplankton photosynthetic activity, biomass and diversity over large aquatic areas. The P&P LIDAR technique is one of the first practical implementations of 'superactive' remote sensing. This presentation summarizes results of six airborne measurement campaigns conducted in 1999-2002 in the Chesapeake Bay, Delaware Bay, Middle Atlantic Bight, and Gulf of Mexico. The P&P technology has been complemented by a Laser Phytoplankton Analyzer (LPA), a shipboard laser fluorometer dedicated to technological advancement in pigment analysis that will be implemented in future LIDAR systems. It combines high-resolution spectral measurements of phytoplankton pigment fluorescence excited at several selected wavelengths with active assessment of the physiological status of the phytoplankton photosynthetic apparatus. Emission/excitation measurements provide a potential for assessing concentrations of photosynthetic accessory pigments (Chlorophyll a, b, c, photosynthetic carotenoids and phycobilins) and identifying major phytoplankton functional groups. The LPA was extensively tested in laboratory experiments with phytoplankton cultures and their mixtures. In November 2002, the LPA was utilized for pigment fluorescence analysis of natural phytoplankton over a range if environmental conditions on a research cruise in the Middle Atlantic Bight and Delaware Bay.

Scientific and Technological Development of Hadrontherapy  

Science.gov (United States)

Hadrontherapy is a novel technique of cancer radiation therapy which employs beams of charged hadrons, protons and carbon ions in particular. Due to their physical and radiobiological properties, they allow one to obtain a more conformal treatment with respect to photons used in conventional radiation therapy, sparing better the healthy tissues located in proximity of the tumour and allowing a higher control of the disease. Hadrontherapy is the direct application of research in high energy physics, making use of specifically conceived particle accelerators and detectors. Protons can be considered today a very important tool in clinical practice due to the several hospital-based centres in operation and to the continuously increasing number of facilities proposed worldwide. Very promising results have been obtained with carbon ion beams, especially in the treatment of specific radio resistant tumours. To optimize the use of charged hadron beams in cancer therapy, a continuous technological challenge is leading to the conception and to the development of innovative methods and instruments. The present status of hadrontherapy is reviewed together with the future scientific and technological perspectives of this discipline.

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

International Nuclear Information System (INIS)

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

Development of laser technology - Development of the wavelength tuning and the output stabilization technology-  

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).

In January 2011 Helmholtz-Zentrum Berlin officially started the realization of the Berlin Energy Recovery Linac Project BERLinPro, whose goal is to develop the accelerator physics and technology required to accelerate a high-current (100 mA) and low emittance beam, as desired by future large scale facilities based on ERLs. In this work the advantages of ERL-based machines are discussed. Overviews of BERLinPro and of a future 6 GeV multiturn light source are given.

Development of decommissioning system engineering technology  

International Nuclear Information System (INIS)

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

Technology innovation for infectious diseases in the developing world.  

Science.gov (United States)

Enabling innovation and access to health technologies remains a key strategy in combating infectious diseases in low- and middle-income countries (LMICs). However, a gulf between paying markets and the endemicity of such diseases has contributed to the dearth of R&D in meeting these public health needs. While the pharmaceutical industry views emerging economies as potential new markets, most of the world's poorest bottom billion now reside in middle-income countries--a fact that has complicated tiered access arrangements. However, product development partnerships--particularly those involving academic institutions and small firms--find commercial opportunities in pursuing even neglected diseases; and a growing pharmaceutical sector in BRICS countries offers hope for an indigenous base of innovation. Such innovation will be shaped by 1) access to building blocks of knowledge; 2) strategic use of intellectual property and innovative financing to meet public health goals; 3) collaborative norms of open innovation; and 4) alternative business models, some with a double bottom line. Facing such resource constraints, LMICs are poised to develop a new, more resource-effective model of innovation that holds exciting promise in meeting the needs of global health. PMID:23849080

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

Latest technological developments in ophthalmic OCT  

International Nuclear Information System (INIS)

Recent developments of ultrabroad bandwidth light sources and detection technology have enabled significant improvement of ophthalmic axial OCT imaging resolution, demonstrating the potential of ultrahigh resolution OCT (UHR OCT) to perform three-dimensional non-invasive optical biopsy, i. e. the in vivo visualization of microstructural morphology in situ, which had previously only been possible with histopathology. Therefore UHR OCT allows detection of intraretinal changes that can be used for diagnosis of retinal disease in its early stages, when treatment is most effective and irreversible damage can be prevented or delayed. Furthermore it may provide a better understanding of the pathogenesis of several macular pathologies as well as the development of new therapy approaches. Other recent developments of ophthalmic OCT include nearly cellular level resolution, depth resolved functional imaging of the living human retina as well as OCT imaging with enhanced penetration into the choroid by employing novel wavelength regions. Using adaptive optics to correct higher order aberrations of the human eye in combination with high speed, three-dimensional UHR OCT enables unprecedented in vivo volumetric visualization of intraretinal morphology. Preliminary results demonstrate visualization of retinal features that might correspond to the terminal bars of photoreceptors at the external limiting membrane. In addition, extensions of UHR OCT are developed that should provide noR OCT are developed that should provide non-invasive depth resolved functional imaging of the retina, including spectroscopic, blood flow or physiologic tissue information. These extensions of OCT should not only improve image contrast, but should also enable the differentiation of retinal pathologies via localized spectroscopic properties or functional state. (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.

Economic Development Impacts in Colorado from Four Vestas Manufacturing Facilities, Wind Powering America Fact Sheet Series  

Energy Technology Data Exchange (ETDEWEB)

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.

Pyro-processing Technology Development in Japan  

International Nuclear Information System (INIS)

Metal fuel cycle with pyro-processing technology has another potential different from oxide fuel cycle with aqueous process. In addition to the advantage of metal fuel fast reactor, such as achieving a high breeding ratio over 1.3, the pyro-processing with metal electrorefining expects that no additional process is required to separate minor actinides and no organic solvent that degrades by radiation and acid is utilized. 'Feasibility Study on Commercialized Fast Reactor (FR) Cycle Systems' in Japan selected the metal fuel fast reactor fuel cycle with metal-electrorefining as the sub-system for future development. CRIEPI has been involving on R and D of pyro-processing technology with metal-electrorefining since 1980's and followed JAERI, that orients to apply on the treatment of spent target with nitride fuel for ADS, and JNC, currently merged to JAEA, and, then, wider collaboration started among CRIEPI/JAERI/JNC. The series verification of process starting with MOX pellets have produced U-Pu alloy after distillation through reduction and electrorefining at the facility installed in Tokai, JAEA. The metal fuel fabrication has started from the stage of U-Pu alloy fabrication from UO2 and PuO2 mixture by electrochemical reduction, and currently succeeds to produce a fuel slag of U-Pu-Zr of 30 cm by injection casting in Oarai, JAEA. The alloys are scheduled to irradiate in JOYO fast reactor core. The development of engineering model of electro-refipment of engineering model of electro-refiner and electrochemical reduction device has successfully conducted by use of UO2 with kg scale. In addition to domestic R and Ds, pyro-processing verification with genuine material is proceeding in the joint study of CRIEPI/ITU. TRU is extracted into cadmium from chloride prepared from HLLW through denitration by reductive extraction in a caisson installed in a hot cell, and, then, electrorefining by use of PHENIX-irradiated metal fuel with minor actinides is scheduled. Thus, the R and D on pyro-processing technology with metal electrorefining is steadily progressed in Japan from the points of flow-sheet verification and engineering scale application. (authors)
