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 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.

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

International Nuclear Information System (INIS)

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

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.

Current Status on Reprocessing Technology of Fast Reactor Fuel Cycle Technology Development (FaCT) Project in Japan -Overview of Reprocessing Technology Development  

Energy Technology Data Exchange (ETDEWEB)

Japan Atomic Energy Agency (JAEA) launched the gFast Reactor (FR) Fuel Cycle Technology Development (FaCT)h Project in cooperation with the Japanese electric utilities in 2006. In the FaCT project, the decision of the adoption of innovative technologies would be made until 2010, and the conceptual design of demonstration and/or commercial facilities based on the results of research and development of innovative technologies until 2015, which would be possible to achieve the development target, such as Safety and Reliability, Sustainability (Environment Protection, Waste management, and Efficient Utilization of Nuclear Fuel resources), Economic Competitiveness and Nuclear Non-proliferation. The future program toward the commercialization would be also proposed until 2015. Pertaining to reprocessing technologies, the advanced aqueous reprocessing system (NEXT: New Extraction System for TRU Recovery) has been developed, which was selected as the most promising concept for commercialization. The Next process is composed of several processes and technologies, and six issues; (1)Disassembly and Shearing, (2)Highly effective Dissolution, (3)Effective uranium pre-recovery by crystallization, (4)Uranium-Plutonium-Neptunium co-extraction and co-stripping, (5)Minor Actinide recovery by extraction chromatography, (6)Salt-free process for waste reduction; have been identified as the innovative technologies to be developed corresponding to each process step. Currently, the development of these issues has been conducted, focusing on the identification of the technological prospect toward the decision of the adoption of innovative technologies in 2010. Also, the design study of commercial facility would be conducted based on the results of research and development, considering the plant optimization such as safety design, maintenance and repair of equipment, remote cell/plant concept, etc. In addition, it is very important to consider the transition from LWR cycle to FBR cycle, because the FBRs will be deployed by replacing LWR with FBR from around 2050. Especially, it is necessary to reprocess the both LWR spent fuels including MOX and FBR spent fuels reasonably from the viewpoint of supply-demand balance of plutonium and to supply the plutonium product to FBR fuel. In Japan, the discussion of the next reprocessing plant will be started in the Japan Atomic Energy Commission from around 2010. So, the study and examination for transition from LWR cycle to FBR cycle, such as mass balance of plutonium considering also isotopic composition, reprocessing plant concept especially on to what extent LWR line and FBR line should share with, investigation and evaluation of candidate process performance and technical issues, etc., would be conducted in cooperation with the related parties in Japan.

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)

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

International Nuclear Information System (INIS)

the document related to the Generation IV deliberation. The difference between domestic and foreign prices and the price fluctuation are taken into account using economic indexes, for example, 'Producer Price Index' published by US Bureau of Labor Statics when we convert the value of equipment cost and material cost in US from document published year to wanted estimation year, and so on. The validation and verification of SCALLE code is carried out by evaluating the construction cost of past demonstration FR plant designed in Japan, and comparing evaluated value by SCALLE code with the evaluated value at the time. As a example of the JSFR construction cost estimation, the ratio of NOAK cost is 74% of FOAK cost.This code is used as basic information to evaluate cost of power generation in FaCT economics evaluation.

Technology in Movies: Fact and Fiction  

Science.gov (United States)

An excellent example of science fiction turned science fact is the Star Trek communicator. It is virtually identical in function to today's cellular phones, but it was envisioned nearly 30 years before it became a common accessory. Many other parallels of Star Trek concepts to everyday life are illustrated in a short article from the winter 2002 Albright College newsletter (1). Researchers at the Australian National University have accomplished a feat that also originated with Star Trek. The team demonstrated the transportation of a beam of light. A BBC news report (2) describes the specifics of the research, and also includes a separate section that ponders whether human transportation will ever be possible. Several of James Bond's gadgets are highlighted at this Web site (3). A few opposing viewpoints are provided, which contrast real spy devices to the ones used by 007. At a trade show held in June 2002, an industry representative suggested that companies should use Bond-like tactics to help in the war on terrorism (4). This could take the form of technology development, and the cooperation between government and corporations was encouraged in the speech amusingly titled "James Bond Saves the USA." A discussion about technology from Bond movies would not be complete without a look at the real-life counterparts of the films' spy devices. The International Spy Museum (5) has a large collection of items from the CIA, KGB, and elsewhere. Some of the amazing gadgets described on this site include a lipstick pistol, a poison gas gun, and a coat with a buttonhole camera. An interesting essay about futuristic visions in science fiction movies is given at this site (6). It traces examples all the way back to the 1903 film A Trip to the Moon. A collection of lesson plans for different grade levels is presented by the NASA Explores program (7). The activities encourage students to think about science fiction's effect on their lives, and how devices once limited to the imagination have become reality. Another resource, provided through NASA's Jet Propulsion Laboratory, is a pair of lectures given in November 2002. They address topics of space exploration, intelligent robots, and how recent advances in these areas compare to science fiction. This site (8) contains the news release about the lectures, while giving a link to the archive where the Web casts can be viewed.

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

International Nuclear Information System (INIS)

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

FY2000 Hanford Technology Deployment Accomplishments Fact Sheets  

International Nuclear Information System (INIS)

Cleaning up the Hanford Site is one of the top priorities for the U. S. Department of Energy. The department is continually looking for ways to expedite cleanup and reduce costs. During Fiscal Year (FY) 2000. Hanford Site staff deployed 24 new technologies, which produced an estimated lifecycle cost savings of 479 million dollars. This is a clear indicator of the impacts new technology has had and will have on the cleanup efforts. The Hanford Site cleanup is focused on the following: Restoring the Columbia River Corridor; Building and operating the tank waste treatment complex to complete the cleanup of highly radioactive tank waste at Hanford; and Transitioning the Central Plateau. Applying innovative science and technology from national laboratories, universities, and private industry is critical to our complex cleanup mission. The 24 new technologies deployed in FY 2000 are significantly higher than our goal of 14 technological deployments. Eleven of these technologies supported restoring the Columbia River Corridor, and seven were involved with the remediation of radioactive tank waste. These deployments produced valuable information to determine the effectiveness of the new technologies in the field and the efficiencies gained over existing cleanup methods. In several cases, the technology deployed presented a solution to a problem where a clear path of remediation had not yet been determined. New and innovative technologies will play a significant role in the cleanup of the Hanford Site and enable remediation to be done more efficiently. Technology is being developed at a staggering pace. This requires excellent communication throughout the scientific and industry arenas. To effect this communication, we have implemented a technology needs process in conjunction with the multi-year work planning process. Through the combination of these two processes, technology developments and deployments address the near-term technology needs and enable us to plan for the strategic needs of the future. This report contains descriptions of the benefits and features of the FY 2000 demonstrations and deployed technologies. We hope you find this information useful in understanding the contributions that new technologies are providing to help accomplish the Hanford cleanup mission

Wind turbines - facts from 20 years of technological progress  

Energy Technology Data Exchange (ETDEWEB)

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

Oxide fuel fabrication technology development of the FaCT project (5). Current status on 9Cr-ODS steel cladding development for high burn-up fast reactor fuel  

International Nuclear Information System (INIS)

This paper describes evaluation results of in-reactor integrity of 9Cr and 12Cr-ODS steel cladding tubes and the plan for reliability improvement in homogeneous tube production, both of which are key points for the commercialized use of ODS steels as long-life fuel cladding tubes. A fuel assembly in the BOR-60 irradiation test including 9Cr and 12Cr-ODS fuel pins has achieved the highest burn-up, i.e. peak burn-up of 11.9at% and peak neutron dose of 51dpa, without any fuel pin rupture and microstructure instability. In another fuel assembly containing 9Cr and 12Cr-ODS steel fuel pins whose peak burn-up was 10.5at%, one 9Cr-ODS steel fuel pin failed near the upper end of the fuel column. A peculiar microstructure change occurred in the vicinity of the ruptured area. The primary cause of this fuel pin rupture and microstructure change was shown to be the presence of metallic Cr inclusions in the 9Cr-ODS steel tube, which had passed an ultrasonic inspection test for defects. In the next stage from 2011 to 2013, the fabrication technology of full pre-alloy 9Cr-ODS steel cladding tube will be developed, where the handling of elemental powder is prohibited in the process.

OCRWM SCIENCE & TECHNOLOGY PROGRAM MATERIALS PERFORMANCE TARGETED THRUST FACT SHEET  

Energy Technology Data Exchange (ETDEWEB)

In severe corrosive or abrasive environments, steel is rarely used since the range of properties available, in existing steels, are insufficient, resulting in the prevalent usage of either corrosion resistant materials like nickel based superalloys or abrasion resistant materials like tungsten carbide based hardmetals. Recently, a host of carbide based alloys including WC-Co-Cr, NiCr-Cr{sub 3}C{sub 2}, WC-Cr{sub 3}C{sub 2}-Ni etc. have been developed in an attempt to bridge the gap between providing both wear and corrosion protection. In this presentation, data will be presented showing how a newly developed steel coating, SAM2X5, with an amorphous/nanocomposite structure can bridge the gap between conventional metallic alloys and ceramic hardmetal performance with excellent combinations of properties including corrosion resistance superior to nickel superalloys in a number of environments and wear resistance approaching that of tungsten carbide cobalt. The unique combination of damage tolerance developed should be especially applicable for the replacement of electrolytic hard chromium.

MHTGR technology development plan  

International Nuclear Information System (INIS)

This paper presents the approach used to define the technology program needed to support design and licensing of a Modular High-Temperature Gas-Cooled Reactor (MHTGR). The MHTGR design depends heavily on data and information developed during the past 25 years to support Large HTGR (LHTGR) designs. The technology program focuses on MHTGR-specific operating and accident conditions, and on validation of models and assumptions developed using LHTGR data. The technology program is briefly outlined, and a schedule is presented for completion of technology work which is consistent with completion of a Final Safety Summary Analysis Report (FSSAR) by 1993

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.

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)

Technology development for safeguards  

International Nuclear Information System (INIS)

The objective of this project are to establish the safeguards technology of the nuclear proliferation resistance to the facilities which handle with high radioactivity nuclear materials like the spent fuel, to provide the foundation of the technical independency for the establishment of the effective management of domestic spent fuels, and to construct the base of the early introduction of the key technology relating to the back-end nuclear fuel cycle through the development of the safeguards technology of the DFDF of the nuclear non-proliferation. The essential safeguards technologies of the facility such as the measurement and account of nuclear materials and the C/S technology were carried out in this stage (2002-2004). The principal results of this research are the development of error reduction technology of the NDA equipment and a new NDA system for the holdup measurement of process materials, the development of the intelligent surveillance system based on the COM, the evaluation of the safeguardability of the Pyroprocessing facility which is the core process of the nuclear fuel cycle, the derivation of the research and development items which are necessary to satisfy the safeguards criteria of IAEA, and the presentation of the direction of the technology development relating to the future safeguards of Korea. This project is the representative research project in the field of the Korea's safeguards. The safeguards technology and equipment developed while accomplishing this project can be applied to other nuclear fuel cycle facilities as well as DFDF and will be contributed to increase the international confidence in the development of the nuclear fuel cycle facility of Korea and its nuclear transparency

Wind energy - The facts. Vol. 5: Market development  

International Nuclear Information System (INIS)

Wind energy is becoming increasingly competitive with conventional sources. However, it is likely that some form of incentive will be required for the foreseeable future, at least until environmental costs are fully internalised or increased economies of scale and technological development makes wind power fully competitive with conventional sources, such as coal and gas, without the need to consider externalities. 'There are currently five main systems to support electricity from renewable energy sources in the EU member states: investment subsidies, fixed price systems, fixed premium systems, auctions, and certificates systems. The idea behind the mechanisms is to offset at least some of the competitive disadvantage for renewable as a consequence of electricity markets neglecting the environmental cost of production from conventional technologies. Low electricity prices are of little benefit if they lead to high costs to society as a whole through higher health care costs and environmental costs levied on current and future taxpayers and citizens. If the environmental costs of power production were reflected in European power prices, wind power and many other renewable energy technologies would not need support, as pointed out in the European Commission's Green Paper on Security of Supply.

Consuming technologies - developing routines  

DEFF Research Database (Denmark)

Routines in daily life are crucial for consumption by households of energy and water and therefore knowledge of how routines develop and change is extremely relevant from a sustainable consumption perspective. Routines emerge, develop and change in close relation with different kinds of everyday technologies and in this article these processes will be investigated from three different perspectives: an historical perspective of how new technologies have entered homes, a consumer perspective of how both houses and new technologies are purchased and finally, as the primary part of the article, a user perspective of how routines develop while these technologies are being used. In the conclusion these insights are discussed in relation to possible ways of influencing routines.

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. [1] R. Merges and R. Nelson, "On the Complex Economics of Patent Scope," Columbia Law Review 90, no. 4 (1990), R. Merges and R. Nelson, "On Limiting or Encouraging Rivalry in Technical Progress: The Effect of Patent Scope Decisions," Journal of Economic Behavior and Organisation 25 (1994). [2] Merges and Nelson, "On the Complex Economics of Patent Scope," 843. [3] Of more than 280 citations of this article listed in the ISI citation index, I can find none that critically-reanalyse the historical case evidence. I examined the titles of all of the 280-odd citing works and selected abstracts and papers, when the title or abstract seemed to suggest the possibility of critical revision.

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. This paper reviews test progress of the CTPC including the initial hot engine test results. Modifications incorporated into the CTPC from the earlier space power demonstrator engine are reviewed as well.

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.

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

Science.gov (United States)

The beliefs people hold about the social and physical world are central to self-definition and social interaction. The current research analyzes reasoning about three kinds of beliefs: those that concern matters of fact (e.g., dinosaurs are extinct), preference (e.g., green is the prettiest color), and ideology (e.g., there is only one God). The domain of ideology is of unique interest because it is hypothesized to contain elements of both facts and preferences. If adults' distinct reasoning about ideological beliefs is the result of prolonged experience with the physical and social world, children and adults should reveal distinct patterns of differentiating kinds of beliefs, and this difference should be particularly pronounced with respect to ideological beliefs. On the other hand, if adults' reasoning about beliefs is a basic component of social cognition, children and adults should demonstrate similar belief representations and patterns of belief differentiation. Two experiments demonstrate that 5-10 year old children and adults similarly judged religious beliefs to be intermediate between factual beliefs (where two disagreeing people cannot both be right) and preferences (where they can). From the age of 5 years and continuing into adulthood, individuals distinguished ideological beliefs from other types of mental states and demonstrated limited tolerance for belief-based disagreements.

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.

Current status of development of pyrometallurgical reprocessing technology by CRIEPI was summarized. As for the electrorefining process, three different electrodes were developed for getting higher process efficiency. The prismatic anode basket which rotates during electrorefining was found to accelerate the fuel dissolution. Collection efficiency and morphology of electrodeposited uranium on steel mandrel cathode was found to vary with anode/cathode area ratio. Paddle-shaped stirrer was developed for liquid cadmium cathode which collects TRUs and uranium simultaneously. Optimal operational conditions such as cathode current density and Reynolds number of stirring were determined for collecting uranium without forming dendrite. As one of the promising way to immobilize the water-soluble salt waste, to synthesize natural occurring mineral which contain halide salt in three dimensional cage structure was proposed. Measured leachability from synthesized mineral which contained FP simulating elements was as low as those from vitrified waste form. (authors)

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.

Technology Development Facility (TDF)  

International Nuclear Information System (INIS)

We have been studying small, driven, magnetic-mirror-based fusion reactors for the Technology Development Facility (TDF), that will test fusion reactor materials, components, and subsystems. Magnetic mirror systems are particularly interesting for this application because of their inherent steady-state operation, potentially high neutron wall loading, and relatively small size. Our design is a tandem mirror device first described by Fowler and Logan, based on the physics of the TMX experiments at Lawrence Livermore National Laboratory (LLNL). The device produces 20 MW of fusion power with a first-wall, uncollided 14-MeV neutron flux of 1.4 MW/m2 on an area of approximately 8 m2, while consuming approximately 250 MW of electrical power. The work was done by a combined industrial-laboratory-university group

Technology Development of Safeguards  

Energy Technology Data Exchange (ETDEWEB)

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

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.

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.

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

Energy Technology Data Exchange (ETDEWEB)

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

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)

Development of fuel service technology  

International Nuclear Information System (INIS)

Related PWR nuclear fuel, strategy and scope of work of the nuclear fuel service technology should be established to develope nuclear fuel service technology and related equipments and tools so as to provide sound PWR nuclear fuel and increase nuclear power plants safety and operability. At present situation, our own PWR nuclear fuel service technology should be established through understanding induced foreign technology transferred along with PWR Fuel Technology Transfer. As a basic research project to establish the strategy and scope of work for the PWR Fuel Service Technology Development, technical informations of foreign technology have been reviewed and strategy and scope of work of the fuel performance inspection and measuring technology and repair equipment design and manufacturing have been studied. In order to preserve safe and economical operation of power plants, mechanical integrity of the nuclear fuel should be insured. Therefore, establishment of nuclear fuel service technology and equipment engineering is the most important supplementary technology. In order to delineate the strategy of nuclear fuel service technology development and clarity our technical position in this special field, related technologies of foreign nuclear fuel technology partners and that of in Korea have been analyzed and compared. Design characteristics of various fuel in operation has neen studied to provide the direction of conceptional design of poolside inspection and measurement equipments as well as damaged fuel repair equipments. Fuel failure mechanisms which have occured in several nuclear power plants have been studied to provide valuable information to improve fuel design, fabrication technology and plant operation condition. Status of reactor coolant activity analysis technique on operating reactors was evaluated for the development of inpile fuel integrity analysis technology. Conceptional design of poolside inspection/measurement equipment and damaged fuel repair equipments was performed to establish strategy in equipment localization. (Author)

JWST Mirror Technology Development  

Science.gov (United States)

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

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

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 EM technology development strategy  

International Nuclear Information System (INIS)

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

Technological development in fisheries management  

DEFF Research Database (Denmark)

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

JWST Mirror Technology Development Results  

Science.gov (United States)

Mirror technology is a critical enabling capability for the James Webb Space Telescope (JWST). JWST requires a Primary Mirror Segment Assembly (PMSA) that can survive launch, deploy and align itself to form a 25 square meter collecting area 6.5 meter diameter primary mirror with a 131 nm rms wavefront error at temperatures less than 50K and provide stable optical performance. At the inception of JWST in 1996, such a capability did not exist. A highly successful technology development program was initiated including the Sub-scale Beryllium Mirror Demonstrator (SBMD) and Advanced Mirror System Demonstrator (AMSD) projects. These projects along with flight program activities have matured and demonstrated mirror technology for JWST. Directly traceable prototypes or flight hardware has been built, tested and operated in a relevant environment. This paper summarizes that technology development effort.

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.

Space technology developments in Malaysia:  

Science.gov (United States)

The venture of space is, by nature, a costly one. However, exploring space is not just an activity reserved for international superpowers. Smaller and emerging space nations, some with burgeoning space programs of their own, can play a role in space technology development and interplanetary exploration, sometimes simply by just being there. Over the past four decades, the range of services delivered by space technologies in Malaysia has grown enormously. For many business and public services, space based technologies have become the primary means of delivery of such services. Space technology development in Malaysia started with Malaysia's first microsatellite, TiungSAT-1. TiungSAT-1 has been successfully launched from the Baikonur Cosmodrome, Kazakhstan on the 26th of September 2000 on a Russian-Ukrainian Dnepr rocket. There have been wide imaging applications and information extraction using data from TiungSAT-1. Various techniques have been applied to the data for different applications in environmental assessment and monitoring as well as resource management. As a step forward, Malaysia has also initiated another space technology programme, RAZAKSAT. RAZAKSAT is a 180kg class satellite designed to provide 2.5meter ground sampling distance resolution imagery on a near equatorial orbit. Its mission objective is to demonstrate the capability of a medium high resolution remote sensing camera using a cost effective small satellite platform and a multi-channel linear push-broom electro-optical instrument. Realizing the immense benefits of space technology and its significant role in promoting sustainable development, Malaysia is committed to the continuous development and advancement of space technology within the scope of peaceful use of outer space and boosting its national economic growth through space related activities.

Lost Circulation Technology Development Status  

Energy Technology Data Exchange (ETDEWEB)

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

Science.gov (United States)

A new capability regarding the U.S. space efforts will be related to the servicing of satellites in orbit utilizing first-generation space station as the collection point or base for Shuttle-delivered payloads. Orbital maneuvering vehicles could move payloads or spacecraft assembled at the Shuttle/space station terminus to other earth orbit locations. It is assumed that such a capability will be initially available in the early 1990's. The benefits provided by satellite servicing in orbit are discussed, taking into account extended satellite lifetimes, lower acquisition cost, improved satellite performance, the possibility to change a satellite's mission, optimized science, and higher satellite reliability. The requirements for Satellite Servicing Technology Development Missions (TDMs) are considered. It is found that existing technology is insufficient, in various areas, to perform the servicing operations. A list is provided of critical technologies which must be developed.

Mobilizing technology for developing countries.  

Science.gov (United States)

A new problem in technology policy-a discipline hitherto largely concerned with the modern industrial sector-is posed by the need for technology suited to creating productive jobs and providing minimum public services at a cost and level of sophistication within the reach of poor people in developing countries. Careful consideration must be given to overall and sectoral development objectives, economic and manpower resources, and the local institutional and sociocultural context. This may indicate the need for both hardware innovation, such as low-cost alternatives to waterborne sewerage, and social ("software") innovation, such as training large numbers of supervisors to implement improved technologies for labor-intensive civil works.

Development of radioisotope tracer technology  

International Nuclear Information System (INIS)

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

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.''

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  

International Nuclear Information System (INIS)

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

Development of RI Target Production Technology  

International Nuclear Information System (INIS)

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

International Nuclear Information System (INIS)

Historical review is given to the light water reactor development in Japan. The first stage was devoted to the construction of research reactors, the second stage to the introduction of foreign technology and the import of commercial reactors, and the third stage is now being devoted to the domestic construction of commercial reactors. As for the present status of the technical ability of LWR construction, Japanese own technologies of aseismatic design, reactor safety, waste treatment, system design, and core management were introduced. More than 90% of reactor components are new produced in Japan. The reason of the success of the Shimane Nuclear Power Plant, Chugoku Electric Power Co., is analyzed from the viewpoints of both hardware and software technologies. The present status of Japanese technology is briefly reviewed in the areas of containment and pressure vessels, steam generators, core management, waste disposal, water quality control, large valves, and piping works. Finally, some future problems are discussed. These include the domestic manufacture of recirculation pumps and control valves and associated large-scale test-loops, the improvement of reliability, the reduction of radiation level, and the advancement of standardization.

Developments in staged combustor technology  

Energy Technology Data Exchange (ETDEWEB)

A staged coal combustor is being developed under a licensing agreement with Florida Power Corporation. This new technology offers life extension for aging cyclone-fired units that are threatened with shut-down because of EPA`s new NOx emission regulations. The combustor is called the CAIRE{trademark} Combustor, for Controlled AIR Emissions. The CAIRE combustor is designed for reduction of NOx, and removal of sulfur and slag in the combustor proper, thus controlling on the front end of the combustion process, the quantity of pollutants that enter a boiler furnace. At present status, the CAIRE Combustor technology has been developed through pilot plant (12 million Btu/hr) operation. A 50 million Btu/hr commercial prototype unit is in the design phase with startup and testing being scheduled for late 1996, early 1997. The goal of this combustor development, when applied to electric utility boilers, is to reduce particulate (also PM-10 and certain HAPS) up to 75 to 80%, reduce nitrogen oxide emissions to 0.30 lb per million Btu of coal fired and to reduce sulfur oxide emissions by 70 to 90%. Further, this combustor is designed for low pressure drop to minimize auxiliary power requirements. With the use of this combustion technique, the three major air emissions pollutants associated with coal combustion can be significantly reduced in one device at a low cost. The advanced technology represented by the CAIRE Combustor, holds the key to low cost and environmentally acceptable (low particulate and acid rain precursors) high sulfur coal combustion. It also provides benefits for combustion of low rank Western coals.

The gas turbine: Present technology and future developments  

International Nuclear Information System (INIS)

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

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.

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

International Nuclear Information System (INIS)

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. The Program is being conducted at the Idaho National Engineering Laboratory (INEL) by the Operating Contractor, EGandG 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 will be used to perform dry consolidation of commercial spent fuel from the Virginia Power (VP) Cooperative Agreement Spent Fuel Storage Cask (SPSC) Demonstration Program and assemblies that had previously been stored at the Engine Maintenance and Disassembly (EMAD) facility in Nevada. Consolidation will be accomplished by individual, horizontal rod pulling. A computerized semi-automatic control system with operator involvement will be utilized to conduct consolidation operations. Special features have been incorporated in the design to allow crud collection and measurement of rod pulling forces. During consolidation operations, data will be 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 will complete in September of 1986oftware will complete in September of 1986. Following installation in the hot cell, consolidation operations will begin in January 1987. Resulting consolidated fuel will be utilized in the VP Cooperative Agreement SFSC Program

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 utilized in the VP Cooperative Agreement SFSC Program

Technology in Sustainable Development Context  

Science.gov (United States)

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

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)

Policy issues inherent in advanced technology development  

Energy Technology Data Exchange (ETDEWEB)

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

Development of Coated Particle Fuel Technology  

Energy Technology Data Exchange (ETDEWEB)

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.

NREL Develops New Controls that Proactively Adapt to the Wind (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

Until now, wind turbine controls that reduce the impacts of wind gusts and turbulence were always reactive -- responding to the wind rather than anticipating it. But with today's laser-based sensors that measure wind speed ahead of the turbine, researchers at the National Renewable Energy Laboratory (NREL) and their industry partners are developing more intelligent controls. The world's first field tests of these controls are currently underway at the National Wind Technology Center (NWTC) at NREL, with plans for future commercialization.

Research and development policy on FBR cycle technology in Japan  

International Nuclear Information System (INIS)

features were evaluated in order to select promising FBR cycle systems that could meet the design requirements that embodied the five development targets: 1) safety; 2) economic competitiveness; 3) efficient utilization of nuclear fuel resources; 4) reduction of environmental burden; and 5) enhancement of nuclear non-proliferation. As a result, the combination of sodium-cooled FBR with oxide fuel, advanced aqueous reprocessing and simplified pelletizing fuel fabrication was selected as the most promising concept for the FBR cycle system. Figure 1 shows major features of the Japanese sodium-cooled FBR. The Atomic Energy Commission of Japan (AECJ) issued the 'Framework of Nuclear Energy Policy' in October of 2005, which is the foundation of Japanese policy on research, development,and utilization of nuclear energy. In this framework, the target for development of FBR cycle technology is commercialization by y approximately 2050. In March of 2006, FBR cycle technology was selected as one of the key technologies of national importance in the third-term 'Science and Technology Basic Plan.' Subsequently, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Economy, Trade and Industry (METI) formulated the action plan f f for the development of nuclear technologies to materialize the framework reviewing the report of FS. Following the action plan, the council of five-parties, which consisted of MEXT, METI, the Federation of Electric Power Companies of Japan (FEPC), the Japan Electrical Manufacturer's Association (JEMA) and JAEA, was set up to discuss the smooth transition from the R and D stage to the demonstration and deployment stages, in the process developing a solid mutual understanding of the issues. The 'Basic Energy Plan,' issued in March of 2007, explains that the FBR cycle development should be promoted as one of the most important technologies, with the aim to commercialize the FBR cycle system by 2050. Following the Japanese policy on FBR cycle technology development, MEXT, METI and JAEA, launched the Fast Reactor Cycle Technology Development (FaCT) project in 2006, in cooperation with the Japanese electrical utilities. Figure2 shows an outline of the development plan toward commercialization of the FBR cycle technology in Japan. In the FaCT project, design and experimental study for the main concept will be implemented in order to present the conceptual designs of the commercial and demonstrative FBR cycle facilities by 2015, along with the development plan to realize them. R and D has progressed to the development stage, to establish the realization of innovative technologies that can meet development targets. Consequently, the development of innovative technologies should be completed by 2015. Thereafter, the FBR cycle development project will enter the introduction stage through a first system demonstration. The demonstration FBR will be launched sometime around 2025. By around 2050, the commercial FBR cycle system will be deployed, based on experiences with the demonstration FBR cycle system. In the FaCT project, Joyo and Monju will play important roles, through demonstration as a reliable power plant and the establishment of sodium handling technology, as well as MA burning and irradiation of materials

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

Energy Technology Data Exchange (ETDEWEB)

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

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.

NASA uses a structured process for managing projects that develop advanced space technologies and transition them into the designs of flight systems. The four-part process consists of formulation, approval, implementation, and transition. In the formulation phase, technology needs are derived from mission concept studies, various technical approaches for meeting the technology needs are identified, technical performance goals called Key Performance Parameters (KPPs) are established, and a project plan is developed. Prior to project approval, an Independent Formulation Review is conducted to ensure that the project objectives are aligned with the mission needs, and that the project is well planned to meet the objectives. In the implementation phase, the technology development project matures the technology, and progress towards the KPPs is evaluated in periodic status reviews. Technology Readiness Levels (TRLs) are used throughout the project lifecycle to assess the progress of technology maturation. In the transition phase, technologies that are successful in achieving the required level of maturity are transitioned to a customer for further development, are used in system designs, or are thoroughly documented for resumption of development at a later date. The customer or end-user of the technology is involved in all phases of the technology development process.

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 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 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 and applications at Fernald  

International Nuclear Information System (INIS)

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

Energy Technology Data Exchange (ETDEWEB)

The paper discusses the technological advances that have been made in dealing with cold climate. Cold climate has an impact on every aspect of a wind energy project, including among others, design of the wind turbine, the economics of the project and safety. The details are shown in a flow chart. There are various instruments for wind measurement, heat cup anemometer and needle mount are two. One of the problems with needle mount is the loss of data during icing events. The paper outlines the solution to this and different types of de-icing and anti-icing systems are also listed. These systems are generally used for energy production. Forecasting is explained using a site with a mast of 126m as exemplar. The objectives of the study included evaluation of wind energy losses due to the cold climate, determination of icing events and study of the atmospheric boundary layer. From the results it can be concluded that cold climate presents a number of challenges but technological advances are nevertheless possible.

Technological opportunities and paths of development  

DEFF Research Database (Denmark)

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

Technology and patent impact on developing countries  

Directory of Open Access Journals (Sweden)

Full Text Available Since the beginning of the 20th century, the world has witnessed technological advances on a massive scale. The miraculous transition in technology has revamped the industrialized world by replacing the obsolescent implements of production and changing the inputs combination. The new technology always begets disparate consequences of the distributional dimensions in the world economy. Innovations have led to new generation products along with new processes of production to replace the old. When outsiders in developing countries employ technology developed by a corporate unit, it entails heavy payment of royalties as specified by the trade-related aspects of intellectual property rights (TRIPs agreement under the World Trade Organization (WTO. The invention of new and sophisticated technology takes place with the help of in-house research by large corporate houses from the advanced nations. The patenting system under the WTO magnifies the perennial egemony of the developed countries in the developing economies of the world.

The development strategy of financial and innovative technologies  

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.

Information and Communication Technology for Rural Development  

Directory of Open Access Journals (Sweden)

Full Text Available Due to the lack of knowledge and use of ICT in rural areas, development is at a very low rate. Some improvement and advancement in the technologies provided by the government but there is no more effect in the development of rural areas. Information and communication technologies are developing day by day but are lessapplicable in rural areas. Lack of communication and resources are the cause of undeveloped. Main problem are in rural areas are electricity, communication, transportation and lack of knowledge about new technology. ICT is not being completely implemented by the government and non government organization for rural and urban areas.Electricity is the main hindrance in development. There may be different basic solution to solve the electricity problem by using solar energy, bio fuels, bio gas, wind energy etc. E-governance and non government organization can develop rural areas with the help of technologies.

Technology development and transfer in environmental management  

International Nuclear Information System (INIS)

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

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 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)

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.

Technology developments applied to healthcare/nursing.  

Science.gov (United States)

Future technology developments as applied to healthcare and particularly nursing were discussed. Emerging technologies such as genetics, small unobtrusive monitoring devices, use of information and communication technologies are as tools to not only facilitate but also promote communication among all parties of the healthcare process. These emerging technologies can be used for ubiquitous healthcare (u-health). The role of nursing in the u-health is fundamental and required for success and growth. Nursing's role will evolve as nurses become 'information-mediators' in a broader-sense than current role. All technologies will ultimately focus on the consumer through 'behind-the-scenes' data collection, which in turn will also allow nurses to analyze these data to improve care. We need to acknowledge an increased presence and or pervasiveness of information technologies as key components of quality healthcare. This sort of acknowledgment will help propel nursing, and healthcare, to increase use of these tools. To develop nurses with these types of skills the nursing education process will require a fundamental change to integrate these technology-sorts of tools as necessary elements for success.

Nuclear environment clean-up technology development  

Energy Technology Data Exchange (ETDEWEB)

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.

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

Foreign cooperative technology development and transfer  

International Nuclear Information System (INIS)

It is the policy of the US Department of Energy (DOE) that, in pursuing the development of mined geologic repositories in the United States, the waste isolation program will continue to actively support international cooperation and exchange activities that are judged to be in the best interest of the program and in compliance with the Nuclear Waste Policy Act of 1982, Sec. 223. Because there are common technical issues and because technology development often requires large expenditures of funds and dedication of significant capital resources, it is advantageous to cooperate with foreign organizations carrying out similar activities. The DOE's Office of Civilian Radioactive Waste Management is working on cooperative nuclear waste isolation technology development programs with the Organization for Economic Cooperation and Development/Nuclear Energy Agency (OECD/NEA), Canada's Atomic Energy of Canada, Limited (AECL), Sweden, Switzerland, and the Federal Republic of Germany. This paper describes recent technology results that have been obtained in DOE's foreign cooperative programs. Specific technology development studies are discussed for cooperative efforts with Canada, OECD/NEA, and a natural analog project in Brazil

Final report of reactor dismantling technology development. Dismantling of JPDR and technology development  

International Nuclear Information System (INIS)

Establishment of reactor dismantling technologies for preparation of future decommissioning of commercial nuclear power plants is extremely important for harmonized development of nuclear energy. For this purpose, the Atomic Energy Commission indicated the strategy for decommissioning of nuclear facilities in the Long-term Nuclear Power Development and Utilization Plan published in 1982. It described that development of technologies necessary for decommissioning of nuclear facilities and dismantling demonstration tests will be conducted on the Japan Power Demonstration Reactor (JPDR), which terminated its initial role. Based on the strategy, the Japan Atomic Energy Research Institute (JAERI) initiated 1981 the reactor dismantling technology development program relating to the JPDR under contract with the Science and Technology Agency on special account for electric power resources development. On the technology development phase, reactor dismantling technologies had been studied over eight items science 1981, then the JPDR dismantling demonstration project started in 1986 by using the developed technologies. The JPDR dismantling demonstration project was safely completed by March 1996, achieving its initial objectives, in which demonstrated was that the dismantling of reactor facilities could be possible with safe manner. In addition, data on dismantling of reactor facilities were collected and accumulated through the project. The experience and the data will be expected to be effectively contributed to future dismantling of commercial nuclear power plants. The outline of the reactor dismantling technology development conducted by JAERI is described in this report. (author)

Development of hydrogen production technology using FBR  

International Nuclear Information System (INIS)

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

The Asia Pacific LNG trade: Status and technology development  

International Nuclear Information System (INIS)

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

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.

In situ remediation: Developing containment technologies  

Energy Technology Data Exchange (ETDEWEB)

The In Situ Remediation Integrated Program (ISR IP) was established by the US Department of Energy`s (DOE) Office of Technology Development (OTD) to advance the state-of-the art of innovative in situ remediation technologies to the point of demonstration, and to broaden the applicability of these technologies to the widely varying site remediation requirements throughout the DOE complex. This program complements ongoing demonstration programs being conducted at several DOE sites. The ISR-IP has been conducting baseline assessments of in situ technologies to support program planning. One of the assessments has focused on evaluating subsurface containment barrier technologies to identify the current state-of-the-art and determine R and D requirements to enable the deployment of these technologies. DOE`s needs are mostly driven by issues concerning the large number of sites requiring remediation, the wide variation among the sites themselves, and the broad range of contaminants at these sites. Many of the sites contain a mixture of organic and inorganic hazardous waste and radioactive waste in a variety of media. Current remedial action strategies for hazardous waste sites are considering containment mostly as an interim action to prevent migration of contaminants from the site until a Record of Decision is made. In some cases, containment is also considered as a remedial action alternative where it is determined to be the best compromise between cost and effectiveness over a relatively short period of time (about 30 years).

Development of safety analysis technology for LMR  

International Nuclear Information System (INIS)

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

NDI technique development for new technologies  

Science.gov (United States)

In the aerospace industry, the space industry in particular, there is a persistent emphasis on knowing the quality of the components, assemblies, and systems. The demand for quality in the space industry is driven by the high cost of finding problems late in assembly and the impediments to repairing hardware on orbit. One source of late problems is commonly attributed to the incorporation of new technologies. In this work as part of an effort to identify gaps in a suite of funded technology development efforts, we used the Risk Roadmap amplified from a systems point of view. This methodology resulted in insights into the origins of some of the problems associated with incorporating new technology, and the need for planning for system accommodation. One of the system accommodation efforts identified by this effort was the need for the development of nondestructive evaluation and inspection (NDE/NDI) techniques to begin sooner, at approximately TRL 3, with respect to the technology, in order to avoid causing a program delay. This paper describes the Risk Roadmap and the other views of the data in the development of the associated systems view that led to this insight.

Technology development for Indian heavy water reactors  

International Nuclear Information System (INIS)

India has been pursuing a policy of self reliance in development of its nuclear power programme. The first stage of development of its three stage programme is based on pressurized heavy water reactors. The choice of this reactor system was primarily based on the Indian nuclear resource profile and the possibility of indigenisation of technology. Today there are seven operating reactors of PHWR type with construction of five more such units in various stages. All these reactors are of 220 MWe capacity each. The first two reactors were built in collaboration with AECL, Canada and are based on the design of Douglas Point reactors. Subsequent reactors have seen progressive design changes consistent with the evolving trends. The objective of this presentation is to present an over view of the technology development aspects in the context of our PHWR based nuclear power programme. 5 refs, 11 figs

Decommissioning Technology Development for Nuclear Research Facilities  

International Nuclear Information System (INIS)

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

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.

NASA GRC Stirling Technology Development Overview  

Science.gov (United States)

The Department of Energy, Lockheed Martin (LM), Stirling Technology Company, and NASA Glenn Research Center (GRC) are developing a high-efficiency Stirling Radioisotope Generator (SRG) for potential NASA Space Science missions. The SRG is being developed for multimission use, including providing spacecraft onboard electric power for NASA deep space missions and power for unmanned Mars rovers. NASA GRC is conducting an in-house supporting technology project to assist in developing the Stirling convertor for space qualification and mission implementation. Preparations are underway for a thermal/vacuum system demonstration and unattended operation during endurance testing of the 55-We Technology Demonstration Convertors. Heater head life assessment efforts continue, including verification of the heater head brazing and heat treatment schedules and evaluation of any potential regenerator oxidation. Long-term magnet aging tests are continuing to characterize any possible aging in the strength or demagnetization resistance of the permanent magnets used in the linear alternator. Testing of the magnet/lamination epoxy bond for performance and lifetime characteristics is now underway. These efforts are expected to provide key inputs as the system integrator, LM, begins system development of the SRG. GRC is also developing advanced technology for Stirling convertors. Cleveland State University (CSU) is progressing toward a multi-dimensional Stirling computational fluid dynamics code, capable of modeling complete convertors. Validation efforts at both CSU and the University of Minnesota are complementing the code development. New efforts have been started this year on a lightweight convertor, advanced controllers, high-temperature materials, and an end-to-end system dynamics model. Performance and mass improvement goals have been established for second- and third-generation Stirling radioisotope power systems.

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.

Space solar cell technology development - A perspective  

Science.gov (United States)

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

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.

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

Science.gov (United States)

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

Development of germline manipulation technologies in livestock  

International Nuclear Information System (INIS)

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

Halifax company is developing voice recognition technology  

Energy Technology Data Exchange (ETDEWEB)

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

Development of Advanced Ceramic Manufacturing Technology; FINAL  

International Nuclear Information System (INIS)

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

Development of Core Design Technology for LMR  

International Nuclear Information System (INIS)

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

Aerocapture Technology Development for Planetary Science - Update  

Science.gov (United States)

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

Technology Development for High Efficiency Optical Communications  

Science.gov (United States)

Deep space optical communications is a significantly more challenging operational domain than near Earth space optical communications, primarily due to effects resulting from the vastly increased range between transmitter and receiver. The NASA Game Changing Development Program Deep Space Optical Communications Project is developing four key technologies for the implementation of a high efficiency telecommunications system that will enable greater than 10X the data rate of a state-of-the-art deep space RF system (Ka-band) for similar transceiver mass and power burden on the spacecraft. These technologies are a low mass spacecraft disturbance isolation assembly, a flight qualified photon counting detector array, a high efficiency flight laser amplifier and a high efficiency photon counting detector array for the ground-based receiver.

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.

Prospects and development of radiation technologies in developing countries  

International Nuclear Information System (INIS)

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

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, by performing in-depth studies especially in the field of reactor physics, safety systems and safety evaluation to realize the above requirements. 90 figs, 50 tabs, 38 refs.

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

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.

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

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.

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.

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.

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. .

Stirling Technology Development at NASA GRC. Revised  

Science.gov (United States)

The Department of Energy, Stirling Technology Company (STC), and NASA Glenn Research Center (NASA Glenn) 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 Glenn 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 nonmagnetic 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. NASA Glenn 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 NASA Glenn when a Hall-effect thruster was successfully operated with a free-piston Stirling power source. Cleveland State University is developing a multidimensional 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.

Energy Technology Data Exchange (ETDEWEB)

The purpose of this project is to develop RI production technology utility 'HANARO' and to construct a sound infra-structure for mass production and supply to domestic users. The developed contents and results are as follows: two types of rig for irradiation in reactor core were designed and manufactured. The safety of OR rig during irradiation was identified through various test and it is used for RI production. The prepared IR rig will be used to performance tests for safety. We prepared two welders and welding jigs for production of sealed sources, and equipments for quality control of the welded materials. Production processes and apparatus Cr-51, P-32, I-125 and Sr-89, were developed. Developed results would be used for routine production and supply of radioisotopes. The automatic Tc-99m extraction apparatus was supplied to Libya under IAEA support. For approval on special form radioactive material of the developed Ir-192 source assembly and projector documents were prepared and submitted to MOST. The high dose rate Ir-192 source(diameter 1.1 mm, length 5.2 mm) for RALS and the laser welding system for its fabrication were developed. Production technologies of Ir-192 sources for destructive test and medical therapy were transferred to private company for commercial supply. The chemical immobilization method based on the self-assemble monolayer of {omega}-functionalized thiol and the sensing scheme based on the beta-emitter labeling method were developed for the fabrication radioimmuno-sensors. Results of this study will be applied to mass production of radioisotopes 'HANARO' and are to contribute the advance of domestic medicine and industry related to radioisotopes.

Overview of NASA GRC Stirling Technology Development  

Science.gov (United States)

The Stirling Radioisotope Generator (SRG) is currently being developed by Lockheed Martin Astronautics (LMA) under contract to the Department of Energy (DOE). The generator will be a high efficiency electric power source for NASA Space Science missions with the ability to operate in vacuum or in an atmosphere such as on Mars. High efficiency is obtained through the use of free-piston Stirling power conversion. Power output will be greater than 100 watts at the beginning of life with the decline in power largely due to the decay of the plutonium heat source. In support of the DOE SRG project, the NASA Glenn Research Center (GRC) has established a technology effort to provide data to ensure a successful transition to flight for what will be the first dynamic power system in space. Initially, a limited number of areas were selected for the effort, however this is now being expanded to more thoroughly cover key technical issues. There is also an advanced technology effort that is complementary to the near-term technology effort. Many of the tests use the 55-We Technology Demonstration Convertor (TDC). There have been multiple controller tests to support the LMA flight controller design effort. Preparation is continuing for a thermal/vacuum system demonstration. A pair of flight prototype TDC s have been placed on continuous operation. Heater head life assessment continues, with the material data being refined and the analysis moving toward the system perspective. Magnet aging tests continue to characterize any possible aging in the strength or demagnetization resistance of the magnets in the linear alternator. A reliability effort has been initiated to help guide the development activities with focus on the key components and subsystems. This paper will provide an overview of some of the GRC technical efforts, including the status, and a description of future efforts.

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.

Development of coated particle fuel technology  

Energy Technology Data Exchange (ETDEWEB)

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 UO{sub 2} kernel obtained to 1.1, and the sintered density and O/U ratio of final UO{sub 2} kernel were above 10.60g/cm{sup 3}. 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.

Reliability studies in a developing technology  

International Nuclear Information System (INIS)

The standard methods of reliability analysis can only be applied if valid failure statistics are available. In a developing technology the statistics which have been accumulated, over many years of conventional experience, are often rendered useless by environmental effects. Thus new data, which take account of the new environment, are required. This paper discusses the problem of optimizing the acquisition of these data when time-scales and resources are limited. It is concluded that the most fruitful strategy in assessing the reliability of mechanisms is to study the failures of individual joints whilst developing, where necessary, analytical tools to facilitate the use of these data. The approach is illustrated by examples from the field of tribology. Failures of rolling element bearings in moist, high-pressure carbon dioxide illustrate the important effects of apparently minor changes in the environment. New analytical techniques are developed from a study of friction failures in sliding joints. (author)

Current developments in TREAT hodoscope technology  

International Nuclear Information System (INIS)

The development of fuel motion monitoring is traced from its inception through present operation and into future programs. After noting the role of fuel motion studies in terms of safety assurance for the LMFBR, the history of in-pile fuel monitoring is reviewed. The operational record of the present TREAT fast neutron hodoscope is summarized with attention to various performance features. Development plans for the TREAT hodoscope are described in some detail. Application of the hodoscope has been considered for eight safety facilities other than TREAT. In addition, there is a possible role for fuel monitoring techniques to be extended to real-time ex-vessel core surveillance in operating reactors. Certain intrinsic strengths of the hodoscope technique for material monitoring are identified. The pattern of development may be characterized as an adaptation of several technologies to fit available requirements and resources

Development of spent fuel remote handling technology  

International Nuclear Information System (INIS)

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 UO2 pellets. A voloxidizer was developed to convert the spent fuel UO2 pellets obtained from the slitting process in to U3O8 powder. Experiments were performed to test the capabilities and remote operation of the developed slitting device and voloxidizer by using simulated rod-cuts and fuel in the ACP hot cell. A telescopic servo manipulator was redesigned and manufactured improving the structure of the prototype. This servo manipulator was installed in the ACP hot cell, and the target module for maintenance of the process equipment was selected. The optimal procedures for remote operation were made through the maintenance tests by using the servo manipulator. The ACP digital mockup in a virtual environment was established to secure a reliability and safety of remote operation and maintenance. The simulation for the remote operation and maintenance was implemented and the operability was analyzed. A digital mockup about the preliminary conceptual design of an enginnering-scale ACP was established, and an analysis about a scale of facility and remote handling was accomplished. The real-time diagnostic technique was developed to detect the possible fault accidents of the slitting device. An assessment of radiation effect for various sensors was also conducted in the radiation environment

Chemical sensors technology development planning workshop  

Energy Technology Data Exchange (ETDEWEB)

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

CROSSCUTTING TECHNOLOGY DEVELOPMENT AT THE CENTER FOR ADVANCED SEPARATION TECHNOLOGIES  

Energy Technology Data Exchange (ETDEWEB)

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

Closed fuel cycle is a prerequisite for the success of the fast reactors to reduce the external dependence of the fuel. In the Indian context, spent fuel reprocessing, with as low as possible out of pile fissile inventory, is another important requirement for increasing the share in power generation through nuclear route as early as possible. The development of this complex technology is being carried out in four phases, the first phase being the developmental phase, in which major R and D issues are addressed, while the second phase is the design, construction and operation of a pilot plant, called CORAL (COmpact Reprocessing facility for Advanced fuels in Lead shielded cell. The third phase is the construction and operation of Demonstration of Fast Reactor Fuel Reprocessing Plant (DFRP) which will provide experience in fast reactor fuel reprocessing with high availability factors and plant throughput. The design, construction and operation of the commercial plant (FRP) for reprocessing of PFBR fuel is the fourth phase, which will provide the requisite confidence for the large scale induction of fast reactors

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.

Technology development for DUPIC process safeguards  

International Nuclear Information System (INIS)

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 244Cm. 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 effoillance 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.

Development of a deep submicron printing technology  

Science.gov (United States)

The objective of this research was to explore the materials and engineering issues for developing a deep submicron printing technology applicable to both planar and curved surfaces. This was achieved through the development of single- and multiple-level printheads fabricated by focused ion beam sputtering and deposition, combined with microcontact printing (muCP) methods. New avenues in the field of pattern transfer via muCP were developed by the first use of the focused ion beam (FIB) for fabrication of master printhead patterns. Several advantages hallmark the use of FIB for this purpose, including rapid prototyping, pattern "error-correction," and aspect ratio preservation. The FIB was used to produce pattern features suitable for sub-100 nm to micron-scale pattern transfer. Advances were made in the development of muCP technology. For the first time, FIB-fabricated printheads were used to transfer patterns via muCP with poly(dimethyl)siloxane (PDMS) and new elastomers, such as an "alternative polymer system B" (APS-B), to both planar and curved target substrates. Features as small as 90 nm have been transferred successfully by muCP on planar target substrates; and features of order 500 nm have been transferred successfully to curved target substrates. The fundamental issue that has been identified in this research that limits the ultimate feature size obtained by muCP is the grain size of Ag films on the target substrates. Quality and small grain size in Ag films are essential to achieving small prints with low defect density and high continuity within features. It was discovered that Ag films are now the limiting factor to smaller feature size in muCP (down to sub-30 nm printhead feature size): not the printhead, elastomer or SAMs. The smallest Ag grains used in this research were prepared by electron beam evaporation (EBE) and were measured at approximately 40 nm by both transmission electron microscopy (TEM) and atomic force microscopy (AFM). New advances were made in the area of multiple-level printhead technology. Multi-level printheads containing up to four independently addressable arrays of 100 elements were developed in this research by combining FIB and muCP fabrication techniques. A major goal was achieved in this research by the fabrication of working prototype multiple level printheads. (Abstract shortened by UMI.)

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.

Technology development needs summary, FY 1995  

International Nuclear Information System (INIS)

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

Development of Core Design Technology for LMR  

Energy Technology Data Exchange (ETDEWEB)

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 key design technologies for STAR  

International Nuclear Information System (INIS)

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

Energy Storage Technology Development for Space Exploration  

Science.gov (United States)

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

Development of new technology in helium refrigerator  

International Nuclear Information System (INIS)

For the practical use of nuclear fusion apparatuses, the adoption of superconducting magnets is unavoidable, and as the additional effective heating method of plasma, neutral beam injection is regarded as important. For superconducting magnets and the cryopumps for NB1, helium liquefying refrigerators are required to produce extremely low temperature close to absolute zero. In Hitachi Ltd., the development of the large helium liquefying refrigerator of expansion turbine type has been advanced early, and in 1968, No.1 machine, and in 1979, No.2 machine with improved reliability and operational performance were developed. So far, four machines were delivered for the projects of nuclear fusion, accelerators and others. As the technical development, in addition to the development of expansion turbines, the development of such peripheral equipment as transfer tubes, liquid helium pumps and automatic control has been forwarded in parallel. In this paper, the new technology related to these peripheral equipment is described. The superinsulator, FRP rod type spacers and liquid nitrogen shield for transfer tubes, a centrifugal liquid helium pump with dynamic pressure gas bearings and the automatic control for a helium liquefying refrigerator using a Hitachi DSC-18 digital controller are reported.

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

loped. It consists of access control and management, various alarm (including perimeter alarm, intrusion alarms, fire alarms), video and audio monitors, intercommunication set and central console. The system can meet technical requirement for safeguards of first rank. Nuclear material accounting is an important aspect of safeguards research at CIAE. The computer software related to material accounting has been developed. It is the important task for scientists at CIAE to design and review nuclear accounting systems in various facilities. For domestic inspection, CIAE is developing necessary elements such as inspection criteria and procedures, inspection equipment and inspection information management. CIAE often holds domestic technical training courses to share our experience in the field of safeguards. At the same time, international cooperation played a very important role. Many scientists from other countries were invited to give lecture on safeguards. Laboratory also sent some scientists abroad for academic and technical exchange. Some scientists have received Agency' technical training on their areas of interest such as nuclear material accountancy and physical protection. In addition, CIAE assisted Agency to hold the training courses on physical protection in March 1998 and June 2000 respectively. In July 1998, Chinese and US scientists worked together to implement a MPC and A demonstration. The Laboratory of Technical Research for Nuclear Safeguards of CIAE was chosen as the site. The integrated MPC and A demonstration is a first project that has brought Chinese and US nuclear scientists together to work for a common goal. The suite of technologies in this demonstration are illustrative of many safeguards and monitoring techniques. CIAE has made great achievement on nuclear material accountancy, physical protection and has developed equipment and technology of NDA and DA. CIAE hope to made deeper, more concrete and innovative technical solution to the many remaining challenges on safeguards. (author)

Development of conformal respirator monitoring technology  

International Nuclear Information System (INIS)

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

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.

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).

IDC Infrasound Pipeline initiative for technology development  

Science.gov (United States)

The International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) automatically processes infrasound data that is later reviewed by interactive analysis; the detected and located events are being systematically included in IDC products. The IDC works on enhancing the automatic system for the identification of valid signals and the optimization of the network detection threshold by identifying ways to refine signal characterization methodology and association criteria. The objective of this study is to reduce the number of associated infrasound arrivals that are rejected from the automatic bulletins when generating the reviewed event bulletins. The study is two-fold, the first part consists of improving the detection accuracy at the station processing stage by enhancing the infrasound signal detector DFX-PMCC (Detection and Feature eXtraction - Progressive Multi-Channel Correlation). The second part separates infrasound data from other waveform technologies at the automatic network processing stage. Infrasound rules in Global Association (GA) are tuned to pursue a lower ratio of false alarms. Once modifications are tested and validated, the updated algorithms will be implemented in the development area of the IDC for further assessment of their performances in fusion with other waveform technologies. In parallel, the Neighbourhood Algorithm (Sambridge, 1999) approach solving geophysical inverse problems is also investigated for infrasound association and location. It has the benefit of not requiring the estimation of travel-time derivative information. Tests are performed using the events from the Infrasound Reference Event Data Base (IRED).

International Nuclear Information System (INIS)

Full text: China Institute of Atomic Energy (CIAE) is a multi-disciplinary institute under the leadership of China National Nuclear Corporation (CNNC). The Laboratory of Technical Research for Nuclear Safeguards was established at CIAE in 1991 to develop safeguards technology and to provide technical assistance to competent authorities for nuclear material management and control, which became one of the key laboratories approved by CNNC in 1993. The main research works for safeguards at CIAE include: nuclear material control and accounting, facilities license review and assessment, domestic inspection, NDA and DA analysis, physical protection and technical training. Research and development of equipment and technique for safeguards has been continuing at CIAE. A variety of NDA equipment that has different resolution and analysis capability has been developed. Method of NDA measurement has been investigated for nuclear material with different characteristics. Mathematics method such as Monte Carlo simulation is applied in NDA. Advanced destructive analysis (DA) instrument is installed at laboratory of CIAE, such as TIMS, ICP-MS and electronic chemistry analyzing system. The high accuracy results of element analysis and isotopic analysis for nuclear material can be obtained. It is possible to measure the types and quantities of nuclear material in a given area by means of NDA and DA. Physical protection system has also been developed. It consists of access control and management, various alarm (including perimeter alarm, intrusion alarms, fire alarms), video and audio monitors, intercommunication set and central console. The system can meet technical requirement for safeguards of first rank. Nuclear material accounting is an important aspect of safeguards research at CIAE. The computer software related to material accounting has been developed. It is the important task for scientists at CIAE to design and review nuclear accounting systems in various facilities. For domestic inspection, CIAE is developing necessary elements such as inspection criteria and procedures, inspection equipment and inspection information management. CIAE often holds domestic technical training courses to share our experience in the field of safeguards. At the same time, international cooperation played a very important role. Many scientists from other countries were invited to give lecture on safeguards. Laboratory also sent some scientists abroad for academic and technical exchange. Some scientists have received Agency' technical training on their areas of interest such as nuclear material accountancy and physical protection. In addition, CIAE assisted Agency to hold the training courses on physical protection in March 1998 and June 2000 respectively. In July 1998, Chinese and US scientists worked together to implement a MPC and A demonstration. The Laboratory of Technical Research for Nuclear Safeguards of CIAE was chosen as the site. The integrated MPC and A demonstration is a first project that has brought Chinese and US nuclear scientists together to work for a common goal. The suite of technologies in this demonstration are illustrative of many safeguards and monitoring techniques. CIAE has made great achievement on nuclear material accountancy, physical protection and has developed equipment and technology of NDA and DA. CIAE hope to made deeper, more concrete and innovative technical solution to the many remaining challenges on safeguards. (author)

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

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.

Fabrication issues and technology development for HELEOS  

International Nuclear Information System (INIS)

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

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.

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).

Development of Coated Particle Fuel Technology  

Energy Technology Data Exchange (ETDEWEB)

UO{sub 2} kernel fabrication technology was developed at the lab sacle(20{approx}30g-UO{sub 2}/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 UO{sub 3} and UO{sub 2} 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 UO{sub 2} 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
