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.

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

International Nuclear Information System (INIS)

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

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 (3). Analysis of sintering behavior for MOX pellet production  

International Nuclear Information System (INIS)

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

Development of oxygen-to-metal ratio of MOX pellet adjustment technology for the simplified MOX pellet fabrication method in the FaCT project  

International Nuclear Information System (INIS)

Oxygen-to-metal (O/M) ratio adjustment technology has been developed for the simplified MOX pellet fabrication method in the FaCT project. Previously, O/M ratio adjustment tests were carried out to prepare low O/M ratio MOX pellets on a laboratory-scale (a few hundred grams MOX scale). In the present study, a small-scale (a few kilograms MOX scale) furnace to adjust O/M ratio of MOX pellets to the targeted value has been developed as the next step. Thermo-fluid dynamics simulations were carried out to confirm flow behavior of gas inside the small-scale furnace, and it was seen that gas was supplied to all MOX pellets without stagnation. O/M ratio adjustment tests using the small-scale furnace and the laboratory-scale furnace were carried out to confirm influence from scale-up, and it was confirmed that the test O/M ratios were nearly equal to the calculation values which were equilibrated to the oxygen potential of gas. The O/M ratios of MOX pellets could be adjusted to the targeted values using the small-scale furnace, similar to when using the laboratory-scale furnace. (author)

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

NREL Collaborates to Improve Wind Turbine Technology (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

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

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.

Robotics Technology Development Program  

International Nuclear Information System (INIS)

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

Transmutation Technology Development  

Energy Technology Data Exchange (ETDEWEB)

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

MMIC packaging technology development  

Science.gov (United States)

Packaging technology for microwave and millimeter-wave monolithic integrated circuits (MMIC's) was developed. Two packaging approaches were investigated for RF performance and mechanical integrity. One is a packaging approach using quartz (fused silica) material and a glass sealing process. The other is a packaging approach using ceramic (92 percent Alumina) material and a co-firing process. Test results indicate both packaging approaches provide wide frequency band and low insertion loss. The quartz package-breadboard components exhibited operating frequency up to 35 GHz, with insertion loss less than 1.30 dB at 35 GHz. Quartz packages were designed and fabricated to investigate reproducibility. Findings from sample fabrication indicate that metallization and glass sealing process for quartz packages requires substantial improvement before reproducibility can be established. Ceramic packages were designed and fabricated for proof-of-concept in support of MMIC packaging technology development. The ceramic packages exhibited operating frequency up to 36 GHz, with insertion loss less than 1.7 dB at 36 GHz. These proof-of-concept MMIC packages not only show low insertion loss and wide frequency band but also demonstrated the hermetic-seal capability and the mechanical strength for many MMIC applications. Current co-fired ceramic process permits cost effectiveness and timely insertion of MMIC's technology.

Pyrometallurgical processing technology development  

International Nuclear Information System (INIS)

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. The experimental and simulated results on the frequencies of acoustic signal according to the leak level were compared

Total inspections over the most components of KAERIT are made with respect to every details including vacuum, mechanical, and electrical ones during the period of reassembling of main body to reinforce the mechanical strength of toroidal field coils. The manufacturing of power supplies for the magnetic field coils is completed as their control system constructions and electrical connections to the main body of the tokamak have been finished this year. Power supply systems for the toroidal field coils, the ohmic heating transformer, and equilibrium field coils are connected to each coil assembly, and the basic circuit characteristics are tested individually. A study on the vacuum technology has been conducted to develop a vacuum regulating system and to establish the KAERIT vacuum cycles. The vacuum vessel is cleaned and examined thoroughly during the period of tokamak disassembling. Also the remote control systems for vacuum regulation and gas injection have been composed and experiments on their system characteristics are conducted. To initiate the developments of data acquisition system and plasma diagnostics, active integrators are developed and a receiver system for electron cyclotron emission is designed as a first step.

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.

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

International Nuclear Information System (INIS)

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

Asian and African Development Trajectories Revisiting Facts and Figures  

Directory of Open Access Journals (Sweden)

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

International Nuclear Information System (INIS)

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

Oil tanker technology developments  

Energy Technology Data Exchange (ETDEWEB)

Probably the four major causes of pollution of the sea from ships are: the failure of the hardware or the ships themselves; the people who operate the ships; the legislation, systems, processes and procedures in use; and fate or the chain of events leading to a pollution incident. The paper firstly examines the scales and types of incidents, their sources, and their causes. It then examines the technological developments in relation to the reliability of hardware, effective systems, and the competence of people. Tanker operations make up 19 per cent of the sources of pollution of the sea by oil, and of this 5 per cent can be attributed to accidents. Yet accidents attract a great deal of attention since they are highly concentrated and highly visible, particularly when they occur near centres of human and wildlife populations. Legislation has a strong influence over 84 percent of oil pollution and the regimes are gradually tightening to reduce the volume of oil from these sources finding its way into the sea. Recent changes to MARPOL legislation are discussed. Developments in design, monitoring systems and human systems that enhance tanker safety and reliablility are discussed. Significant improvements can be made to oil tanker design and operation at a relatively small marginal capital and operating cost increase by ensuring that technical integrity is continuously improved.

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

International Nuclear Information System (INIS)

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

Robotics Technology Development Program. Technology summary  

Energy Technology Data Exchange (ETDEWEB)

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

Key technological challenges for JSFR development  

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

The Clean Coal Technology Demonstration Program (CCT Program), a model of government and industry cooperation, responds to the Department of Energy's (DOE) mission to foster a secure and reliable energy system that is environmentally and economically sustainable. The CCT Program represents an investment of over$5.2 billion in advanced coal-based technology, with industry and state governments providing an unprecedented 66 percent of the funding. With 26 of the 38 active projects having completed operations, the CCT Program has yielded clean coal technologies (CCTs) that are capable of meeting existing and emerging environmental regulations and competing in a deregulated electric power marketplace. The CCT Program is providing a portfolio of technologies that will assure that U.S. recoverable coal reserves of 274 billion tons can continue to supply the nation's energy needs economically and in an environmentally sound manner. As the nation embarks on a new millennium, many of the clean coal technologies have realized commercial application. Industry stands ready to respond to the energy and environmental demands of the 21st century, both domestically and internationally, For existing power plants, there are cost-effective environmental control devices to control sulfur dioxide (S02), nitrogen oxides (NO,), and particulate matter (PM). Also ready is a new generation of technologies that can produce electricity and other commodities, such as steam and synthetic gas, and 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

Fact sheet  

Energy Technology Data Exchange (ETDEWEB)

The annual publication Fact sheet describes the exploitation of oil and gas reserves on the Norwegian Continental Shelf. The Fact sheet provides information on political, economic, industrial and technological aspects of the petroleum sector. Editing was completed 1 April 1990. During 1989, 28 exploration wells were initiated on the Norwegian Continental Shelf. Eight of these wells were delineation wells. Of the 20 exploration wells drilled in 1989, 17 were drilled in new structures where no drilling had taken place before. Hydrocarbones were proven in three of these wells, while 11 wells turned out to be dry. The three finds were all done in the North Sea. As at 31 December 1989, a total of 626 exploration wells have been initiated on the Norwegian Continental shelf since the start. 177 of these were appraisal wells. In the course of 1989 the Storting (Parliament) received no new Plans for Development and Operations. However, the Revised Plan for Development of the field Sleipner East was approved by the Storting 17 November 1989.

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.

Multichip module technology development  

International Nuclear Information System (INIS)

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

Value of technology for development  

International Nuclear Information System (INIS)

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

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 vesselsâ??a mechanism referred to as â??technological creep.â? 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.

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

Energy Technology Data Exchange (ETDEWEB)

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

Pyroprocessing technology has advantages over the aqueous process: less proliferation risk, treatment of spent fuel with relatively high heat and radioactivity, compact equipment, etc. The addition of an oxide reduction process to the pyroprocessing metal fuel treatment enables handling of oxide spent fuel, which draws a potential option for the management of spent fuel from the PWR. In this context, KAERI has been developing pyroprocessing technology to handle the oxide spent fuel since the 1990s. This paper describes the current status of pyroprocessing technology development at KAERI from the head-end process to the waste treatment. A unit process with various scales has been tested to produce the design data associated with the scale up. A performance test of unit processes integration will be conducted at the PRIDE facility, which will be constructed by early 2012. The PRIDE facility incorporates the unit processes all together in a cell with an Ar environment. The purpose of PRIDE is to test the processes for unit process performance, operability by remote equipment, the integrity of the unit processes, process monitoring, Ar environment system operation, and safeguards related activities. The test of PRIDE will be promising for further pyroprocessing technology development

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.

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.

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.''

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

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

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

Energy Technology Data Exchange (ETDEWEB)

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

Wireless Power Transmission Technology Development and Demonstrations  

Science.gov (United States)

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

Developments in fuel cell technology  

International Nuclear Information System (INIS)

Fuel cells convert chemical energy directly into electrical energy with high efficiency and low emission of pollutants. A fuel cell consists of two electrodes around an electrolyte. There are five types of fuel cells under active development i.e.; The alkaline fuel cell (AFC), Polymeric- electrolyte- membrane fuel cell (PEMFC), Phosphoric acid fuel cell (PAFC), Molten carbonate fuel cell (MCFC) and Solid oxide fuel cell (SOFC). The role of material science and engineering in the development of fuel cell technology is critical. Fabrication of triple-phase-boundary structures involving electrolytes, electronic conductors and gaseous reactants is important. Development of electrocatalysts (Pt or Pt alloys) by depositing small nano-crystallites on carbon was one of the major achievements for commercial preparation of fuel cells. A fuel cell system also incorporates relevant balance of plant items such as pumps, valves, heat exchangers and piping. Recent progress in the search and development of innovative materials is summarized. Applications of electrochemistry in fuel cell development are discussed. Our experiences with the development of a small indigenous fuel cell are described. Electrodes were prepared from graphite and were heat-treated. Platinum catalyst was deposited on these electrodes by chemical deposition. AFC was assembled from these electrodes and voltage output of this cell was near the optimum levels. Some basic studies were done and results are reported. (author)

Research and Development Policy on FBR Cycle Technology in Japan  

International Nuclear Information System (INIS)

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

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("2"3"5U: 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 "2"5"2Cf 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 (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

Development of uranium enrichment technology  

International Nuclear Information System (INIS)

No. 1 centrifugal separator for uranium enrichment was made in 1959 by the Institute of Physical and Chemical Research. The progress of the development of uranium enrichment technology since then is described. The evaluation of centrifugal separators is made on their separating performance, power consumption, reliability, life time, manufacturing cost and others. The centrifugal separators developed in Japan have not very large separating performance, but their manufacturing cost is low, and the periodic repair is unnecessary. The separating performance depends on the rotating speed and length of the drum. The material enduring high speed rotation had to be developed, and the high accuracy to assemble the rotating drum, the development of balancing technique for the rotating drum and damper mechanism were necessary to surpass the critical vibration. At present, the development of several types has been finished, which can be adopted in the actual enrichment plants with international competitiveness. The full cascade test has been experienced since 1973, using the cascades comprising several hundreds of centrifugal separators. Also the power source system, the raw material supply system, the system for recovering uranium hexafluoride, and the instrumentation and control system were installed in the cascade test plant. The pilot plant with 1000 machines is expected to start the operation in the summer of 1979. (Kako, I.)

Issues in World Commission on Dams report development: inconsistencies between the facts found and the guidelines  

Science.gov (United States)

The World Commission on Dams (WCD) is an international and independent body consisting of 12 dam experts. It published its only and final report Dams and Development in November 2000 after 2.5 years of preparation. The report is composed of two parts: part I contains the facts found and part II contains recommendations. The aim of part I was to present solid facts about both the benefits and the costs of building dams. The aim of part II is not as clear to the authors. Many members of the media in developed nations believed that part II proposed a concrete set of guidelines, a blueprint for the future. This perception was shared with many environmentally concerned non-governmental organizations, who regarded the guidelines in part II as a blueprint to be observed. However, in February 2001, the Chair of the WCD stated that the guidelines were intended only to offer guidance, and are not a rigid regulatory framework. The question to be asked and answered is whether the guidelines in part II may be regarded as a rigid framework to be implemented as it stands. The authors do not regard the guidelines in part II as ready for implementation, as this part of the report has many shortcomings, which stem from a missing link between part I and part II, in that the latter does not reflect the findings in the former. Moreover, part II of the report includes some suggestions that are not based on findings in part I. This paper tries to answer the following questions about the WCD's report: (1) Why was the set of guidelines in part II regarded as the blueprint by so many people and institutions? (2) What incompatibilities exist between the two parts of the report? (3) Why were such incompatibilities mostly disregarded in developing the report? (4) How may the set of suggested guidelines in part II become an operational instrument.

Development of DUPIC safeguards technology  

International Nuclear Information System (INIS)

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

Steam generator decontamination technology development  

International Nuclear Information System (INIS)

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

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.

(Radioactive waste incineration technology development)  

Energy Technology Data Exchange (ETDEWEB)

At the request of the International Atomic Energy Agency (IAEA), technical assistance was provided to the Korea Atomic Energy Research Institute (KAERI) in the field of radwaste incineration and related off-gas treatment operations. The traveler provided the requested technical consolations and, in the process, obtained an understanding of the Republic of Korea's plans for the management of the the wastes from the country's nuclear power plants and research facilities. The government of the Republic of Korea has tasked KAERI to develop the facilities for treating and disposing of the wastes from the country's nuclear facilities in an environmentally responsible manner. As a step in that direction, the Radwaste Treatment Department at KAERI is developing the technology and the plans for the incineration of burnable low-level radwaste, which comprises about 35% of the wastes generated by the nuclear facilities. The incineration program at KAERI appears to be well planned. They have operated a 5-kg/h process design unit incinerator to gather the process data for scaling up the operation to a 30-kg/h demonstration plant. This demonstration plant is presently being built, with startup operations scheduled for January 1991. Data from the demonstration plant are proposed to be used for building a 120-kg/h commercial radwaste incineration facility.

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 borehole sealing technology  

International Nuclear Information System (INIS)

As a part of the geoscientific research in JNC Tono Geoscience Center, we are conducting the borehole investigation as a method of surveying techniques to gain an understanding of geological environment characterization (geology/geological structure, rock hydraulic characteristics, ground water geochemical characteristics and rock mechanics) from surface to deep underground. The borehole for the borehole investigation is used for monitoring hole after the borehole investigation. Since the borehole may act as a passage of groundwater flow and disturb the geological environment artificially, it has to be sealed in finally. Moreover, the hydraulic testing and the geochemical analysis of groundwater that be conducted in the zones injected some kind of lost circulation materials might be impacted on the accuracy of test result. The actual technologies regarding to these themes was researched and evaluated. In the second step, clarification of problems and procedure of R and D for solution of these problems was examined. In order to estimate the effect of lost circulation materials on hydraulic testing, a laboratory test of borehole behavior was performed using a scale model that consisted of a borehole and a water-loss zone. In this test, we found out that the lost circulation material was desorbed from the water-loss zone by back-flow action. It was proved by the test that there is little influence from lost circulation materials on hydraulic testing. Investigation regarding borehole sealing technology was conducted in literature search and interview to overseas researchers. In consequent, three kinds of materials - bentonite clay, bentonite pellet, and ethanol bentonite, were selected as effective sealing material. Moreover, five kinds of methods were selected as effective sealing methods. In water permeability test of sealing material, three kinds of sealing materials indicated lower permeability - order of 10-11 m/sec, and it was evaluated that it could be worked as effective seal. The sealing methods were considered that it was necessary to choose according to borehole condition and sealing material. In addition, the verification method after sealing could not be found in existing technique, and it is necessary to study and develop it in future. (author)

Development of Coated Particle Fuel Technology  

International Nuclear Information System (INIS)

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

Mobile Sensor Technologies Being Developed  

Science.gov (United States)

The NASA Glenn Research Center is developing small mobile platforms for sensor placement, as well as methods for communicating between roving platforms and a central command location. The first part of this project is to use commercially available equipment to miniaturize an existing sensor platform. We developed a five-circuit-board suite, with an average board size of 1.5 by 3 cm. Shown in the preceding photograph, this suite provides all motor control, direction finding, and communications capabilities for a 27- by 21- by 40-mm prototype mobile platform. The second part of the project is to provide communications between mobile platforms, and also between multiple platforms and a central command location. This is accomplished with a low-power network labeled "SPAN," Sensor Platform Area Network, a local area network made up of proximity elements. In practice, these proximity elements are composed of fixed- and mobile-sensor-laden science packages that communicate to each other via radiofrequency links. Data in the network will be shared by a central command location that will pass information into and out of the network through its access to a backbone element. The result will be a protocol portable to general purpose microcontrollers satisfying a host of sensor networking tasks. This network will enter the gap somewhere between television remotes and Bluetooth but, unlike 802.15.4, will not specify a physical layer, thus allowing for many data rates over optical, acoustical, radiofrequency, hardwire, or other media. Since the protocol will exist as portable C-code, developers may be able to embed it in a host of microcontrollers from commercial to space grade and, of course, to design it into ASICs. Unlike in 802.15.4, the nodes will relate to each other as peers. A demonstration of this protocol using the two test bed platforms was recently held. Two NASA modified, commercially available, mobile platforms communicated and shared data with each other and a central command location. Web-based control and interrogation of similar mobile sensor platforms have also been demonstrated. Expected applications of this technology include robotic planetary exploration, astronaut-to-equipment communication, and remote aerospace engine inspections.

Research and development policy on FBR cycle technology in Japan  

International Nuclear Information System (INIS)

The Fast Breeder Reactor (FBR) and its fuel cycle (hereinafter 'FBR cycle') technology will provide harmonic solutions for global energy resource and environment issues.In Japan, the significance of FBR cycle technology development has been recognized for decades. The Japan Atomic Energy Agency (JAEA) has been the principal agency for the FBR cycle development in Japan. The experimental fast reactor, Joyo, had been successfully operated for about 30 years, beginning in 1977. The prototype FBR, Monju, achieved initial criticality in 1994. Monju is designed on the basis of research results gleaned from Joyo. Monju has the role of confirming the technological data base for design and safety evaluation tools, and of accumulating operation experiences for sodium-cooled reactors, with an eye toward commercialization. Both reactors' operations have been suspended since 2007 and 1995, respectively, due to troubles; presently, JAEA is preparing for the re-launch of operations. Furthermore, the development of FBR spent fuel reprocessing technologies was initiated in 1975, and JAEA has successfully achieved MOX fuel fabrication at the Plutonium Fuel Center, as far back as 1972. In 1999, the 'Feasibility Study on Commercialized FBR Cycle Systems (FS)' was initiated to present an appropriate picture of FBR cycle technology commercialization by 2015, as well as its research and development (R and D) program. In this study, conceptual design features were evaluated in order to 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 o

The Developing Science and Technology List  

Science.gov (United States)

The Militarily Critical Technologies Program (MCTP), a DoD responsibility directed by Congress, provides a systematic, ongoing assessment and analysis of goods and technologies to determine those technologies that would permit significant advances in the development, production and use of military capabilities of potential adversaries and those that are being developed worldwide that have the potential to significantly enhance or degrade US military capabilities in the future. The program's objective is to characterize the technologies, including quantitative values and parameters, and assess worldwide technology capabilities. The MCTP is composed of two documents, the well known Militarily Critical Technology List (MCTL), and one called the Developing Science and Technologies List (DSTL). Both are products of the MCTP process. However, the DSTL is a compendium of scientific & technological capabilities being developed worldwide which have the potential to significantly enhance or degrade U.S. military capabilities starting five years into the future. The DSTL is sponsored by DDR&E and is used by other government organizations and agencies as well to aid in the prioritization and understanding of new technologies being developed worldwide. Working within an informal structure, TWG members are composed of government, industry and academia subject matter experts, who strive to produce objective analyses across each technology areas. This process and details of the current MCTP/DSTL are outlined in this poster paper. This poster paper focuses on Space Optics technology to provide a sample of the DSTL content.

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.

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.

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 capital costs, the investment value was mostly in the more capital-intensive wind energy and hydropower projects

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

Science, technology and cooperation among developing countries  

International Nuclear Information System (INIS)

The role science and technology play in the economic development of a country needs no special emphasis. Studies about the impact of technology on productivity have been carried out in several developed countries, and in the U.S. alone, it was determined that technological progress has contributed more than one-third to the growth rate of labor productivity. Various inputs, as listed below, are essential for science and technology to play an effective role in the developing countries, and cooperation on a regional, continental, and worldwide scale is a necessity. In this respect, the following points are worth mentioning: a) Natural resurces, trained manpower, and funds are limited to varying degrees in developing countries. b) Solutions to vast major problem issues, such as population, food, unemployment, etc., are urgent. c) There are large numbers of scientific and technological problems that are peculiar and common to developing countries. d) In the nuclear field, research and development are costly and time consuming and require highly trained technical manpower. It is particularly important for developing countries to mutually develop the necessary technology for medium- and smallsize reactors as the technology available from the developed countries is based primarily on the larger sized units

Technology development and applications at Fernald  

Energy Technology Data Exchange (ETDEWEB)

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.

Technological development in cold climate  

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.

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.

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

New developments in ultracapacitor technology  

Science.gov (United States)

The objective of this in-house research project is to develop new high surface area (HSA) electrodes suitable for use as primary internal components of ultracapacitors. Ultracapacitors are low voltage charge storage devices that do not involve chemical reactions to store or release energy; instead, planar HSA electrodes are employed to hold charge across a thin layer of electrolyte. In the past, ultracapacitor development has relied heavily upon use of exotic electrode materials (i.e., platinum group metal oxides) which are stable in aqueous sulfuric acid electrolyte. Ultracapacitor availability has been hindered by the lack of more common substitute electrode materials, such as HSA molybdenum nitride, which possess adequate electronic conductivity and also offer equivalent long term compatibility with the electrolyte.

Development of Nuclear Analytical Technology  

International Nuclear Information System (INIS)

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 252Cf 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

Clean coal technology development in China  

International Nuclear Information System (INIS)

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

Technological Levels, Technological Transfer, and Cooperation for Development  

Directory of Open Access Journals (Sweden)

Full Text Available Transfer of Technology (TT, the article first presents a series of reflections concerning the connection between technology and people both within the individual as well as the collective sphere. The paper then outlines points for debate regarding the inherentcharacteristics of the technologies themselves that should be kept in consideration in any TT design, whose ultimate aim is utility and sustainability. Next, the author describes the agents and mechanisms that are active in TT from the North. Based on examples of TT programs as implemented by the EU and Spain, its is shown that the processes of TT are in a state of rapid innovation, and that technology is prioritized, subsidized and favored in the rich world by these agents and mechanisms. Due cause arises, though, to question the content and models of TT from the point of view of the South. This paper underscores the role that Cooperation for Developmentcan play in the TT process by way of describing the actors involved in the South, analyzing the impacts of determined technologies and their constrained accessibility, and sketching the major guidelines that ought to be stressed to favor balanced, sustainable development.

HUMID AIR TURBINE CYCLE TECHNOLOGY DEVELOPMENT PROGRAM  

Energy Technology Data Exchange (ETDEWEB)

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

Fission Surface Power Technology Development Status  

Science.gov (United States)

Power is a critical consideration in planning exploration of the surfaces of the Moon, Mars, and beyond. Nuclear power is an important option, especially for locations in the solar system where sunlight is limited in availability or intensity. NASA is maintaining the option for fission surface power for the Moon and Mars by developing and demonstrating technology for an affordable fission surface power system. Because affordability drove the determination of the system concept that this technology will make possible, low development and recurring costs result, while required safety standards are maintained. However, an affordable approach to fission surface power also provides the benefits of simplicity, robustness, and conservatism in design. This paper will illuminate the multiplicity of benefits to an affordable approach to fission surface power, and will describe how the foundation for these benefits is being developed and demonstrated in the Exploration Technology Development Program s Fission Surface Power Project.

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.

Fusion reactor related technologies development in ASIPP  

International Nuclear Information System (INIS)

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

AFCI Safeguards Enhancement Study: Technology Development Roadmap  

Energy Technology Data Exchange (ETDEWEB)

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

CROSSCUTTING TECHNOLOGY DEVELOPMENT AT THE CENTER FOR ADVANCED SEPARATION TECHNOLOGIES  

Energy Technology Data Exchange (ETDEWEB)

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

Development of sodium technology in fast reactors  

International Nuclear Information System (INIS)

As for the development of liquid sodium technology in Japan, though it had been started in the latter half of 1950s, the sodium test facility of large scale was constructed in Oarai Engineering Center for the development of technology to construct Joyo after the start of Power Reactor and Nuclear Fuel Development Corp. in 1967. After the Joyo attained the criticality in 1977, the effort of development has been concentrated on the realization of Monju. The test facilities for the development of sodium technology are more than 30 including a large 50 MW steam generator testing facility and a sodium equipment structural testing facility. The fields of technology spread over wide range, that is, the development of large equipment, the flow and heat transfer of sodium, the compatibility of materials with sodium, instrumentation, purity control, radioactive sodium, chemical analysis, sodium cleaning, fire fighting techniques and so on. In this report, the fields of development related to sodium itself are described, that is, purity control, the deposition of sodium vapor, sodium cleaning and fire fighting. On the purity control, the purifying of sodium, on-line measurement, chemical analysis and the behavior of radioactive nuclides are mentioned, paying attention to the impurity in sodium. (Kako, I.)

Science and technology for wealth and health in developing countries.  

Science.gov (United States)

It is now widely accepted that the developing world needs to invest in science and technology or risk falling behind as the technology gap between the North and South widens. However, these investments must be balanced by continued investment in basic population-wide services, such as healthcare and water supply and sanitation. Achieving this balance is a matter of ongoing debate in policy circles, and leaders and policy-makers in developing countries often have to make difficult decisions that pit investment in new technologies and capacity-building in science and technology against basic population-wide services such as healthcare and water supply and sanitation. The tension is underscored by evidence which suggests that rapidly industrializing economies, like in China, India and Brazil, are actually experiencing a rise in economic and health disparities among their populations. The fact that poor people in an industrializing country must fall behind while the rest of the country marches ahead does not have to be an inevitable outcome of industrialization. This article shows that science and technology can make an important and vital contribution to development, using public health as an example. It suggests the need to focus investments in science and technology in such a way that they can have a positive impact on public health. For instance, the use of simple, hand-held molecular diagnostic tools can help unskilled health workers rapidly and accurately diagnose diseases, thus helping to reduce healthcare costs due to delayed or incorrect diagnoses. Recombinant vaccines can mitigate the risk of infection associated with live or attenuated vaccines, while needle-less delivery methods can help contain the spread of blood-borne infections. Critical to making technology investments work for population health are government policies and strategies that align public health goals and technology priorities. Such policies can include cross-sectoral training programs to improve dialogue between the technology and health sectors, setting up technology transfer cells to increase commercialization of health research relevant to local needs, and leveraging the phenomenon of low-margin high-volume marketing for health products.

Development of national safeguards inspection technology  

International Nuclear Information System (INIS)

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

International Nuclear Information System (INIS)

This report identifies the main technical issues facing the in situ vitrification (ISV) application to buried waste, and presents a plan showing the top-level schedule and projected resources needed to develop and demonstrate the technology for meeting Environmental Restoration Department (ERD) needs. The plan also proposes a model strategy for the technology transfer from the Department of Energy's Office of Technology Development (DOE-OTD) to the Office of Environmental Restoration (DOE-ER) as the technology proceeds from issues resolution (development) to demonstration and remedial readiness. Implementation of the plan would require $34,91 1K in total funding to be spread in the years FY-93 through FY-98. Of this amount, $10,183K is planned to be funded by DOE-OTD through the ISV Integrated Program. The remaining amount, $24,728K, is recommended to be split between the Department of Energy (DOE) Office of Technology Development ($6,670K) and DOE Office of Environmental Restoration ($18,058K)

Nuclear environment clean-up technology development  

International Nuclear Information System (INIS)

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

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.

ISO: international standards development for nuclear technology  

International Nuclear Information System (INIS)

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

In-core thermionic technology development program  

International Nuclear Information System (INIS)

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

Strategic alliances in engineering, technology and development  

International Nuclear Information System (INIS)

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

Development of zirconium alloy tube manufacturing technology  

Energy Technology Data Exchange (ETDEWEB)

In late 2004, Korea Nuclear Fuel Company (KNF) launched a government funded joint development program with Westinghouse Electric Co. (WEC) to establish zirconium alloy tube manufacturing technology in Korea. Through this program, KNF and WEC have developed a state of the art facility to manufacture high quality nuclear tubes. KNF performed equipment qualification tests for each manufacturing machine with the support of WEC, and independently carried out product qualification tests for each tube product to be commercially produced. Apart from those tests, characterization test program consisting of specification test and characterization test was developed by KNF and WEC to demonstrate to customers of KNF the quality equivalency of products manufactured by KNF and WEC plants respectively. As part of establishment of performance evaluation technology for zirconium alloy tube in Korea, KNF carried out analyses of materials produced for the characterization test program using the most advanced techniques. Thanks to the accomplishment of the development of zirconium alloy tube manufacturing technology, KNF is expected to acquire positive spin off benefits in terms of technology and economy in the near future.

Arm development review of existing technologies  

International Nuclear Information System (INIS)

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

Toward An Information And Communication Technology Development In Developing Countries  

Directory of Open Access Journals (Sweden)

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

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

Decommissioning Technology Development for Nuclear Research Facilities  

Energy Technology Data Exchange (ETDEWEB)

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

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

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.

Development of safety analysis technology for LMR  

International Nuclear Information System (INIS)

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

Development of Advanced Ceramic Manufacturing Technology; FINAL  

International Nuclear Information System (INIS)

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

56th and Walnut: A Philly Gut Rehab Development; Philadelphia, Pennsylvania (Fact Sheet)  

Energy Technology Data Exchange (ETDEWEB)

Load-bearing brick-masonry multifamily buildings are prevalent in urban areas across much of the Northeast and mid-Atlantic. In most instances, these buildings are un-insulated unless they have been renovated within the past two decades. Affordable housing capital budgets typically limit what can be spent and energy improvements often take a back seat to basic capital improvements such as interior finish upgrades and basic repairs. The Consortium for Advanced Residential Buildings (CARB) is researching cost effective solution packages for significant energy efficiency and indoor air-quality improvements in these urban buildings. To explore how these low-cost retrofits can effectively integrate energy efficiency upgrades, CARB partnered with Columbus Property Management and Development, Inc. on a community-scale gut rehabilitation project located at 56th Street and Walnut Street in Philadelphia, consisting of 32 units in eleven 3-story buildings. These buildings were built in the early 1900s using stone foundations and solid brick-masonry walls. They were renovated in the 1990s to have interior light gauge metal framing with R-13 batt in the above-grade walls, induced-draft furnaces, and central air conditioning.

Development of FBR Fuel Cycle Technology in Japan  

International Nuclear Information System (INIS)

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

Development of the centribaric dewatering technology  

Energy Technology Data Exchange (ETDEWEB)

The solid-solid separation processes employed by modern coal preparation plants require large amounts of process water. After cleaning, the unwanted water must be removed from the surfaces of the particles using mechanical dewatering equipment such as filters or centrifuges. Unfortunately, the existing processes that are used to dewater fine particles are inefficient in terms of moisture reduction and/or solids recovery. In light of these problems, a new ultrafine dewatering process called the Centribaric technology has been developed. This novel device combines centrifugation and pressure filtration within one process to substantially reduce moisture over what can be achieved using conventional dewatering systems. This article discusses the evolution of the Centribaric technology from early research through commercial development and presents data from recent laboratory, pilot-plant, and in-plant test programs.

Facts First  

Energy Technology Data Exchange (ETDEWEB)

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

EXCEDE Technology Development III: First Vacuum Tests  

CERN Document Server

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

Development of LWR MOX Fuel Technology  

Energy Technology Data Exchange (ETDEWEB)

The manufacturing and performance analysis technology for LWR MOX fuel was developed in KAERI and two test MOX fuel rods were manufactured in cooperation with PSI of Switzerland. The two test fuel rods were successfully irradiated in the Halden reactor up to 50,000 MWd/tHM. The irradiation test produced various in-pile data confirming their integrity and good performance. Manufacturing and performance analysis technology for nuclear fuel can only be confirmed by the irradiation test and subsequent post-irradiation examination(PIE). In this project, COSMOS code developed for MOX fuel was validated by the in-pile data obtained from the irradiation tests for many MOX fuel rods. To assess objectively the in-pile performance of the two test MOX rods, a reference MOX fuel was irradiated under the same conditions in the Halden reactor. Manufacturing and performance analysis technology for LWR MOX fuel developed in this project was analyzed and imporved using the data produced in the Halden irradiation test and subsequent PIE on the two test MOX rods

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-  

Energy Technology Data Exchange (ETDEWEB)

It is believed that it is easier for Korea to become self-reliant in PHWR technology than in PWR technology, mainly because of the lower design pressure and temperature and because of the simplicity, economy, flexibility of the fuel cycle in comparison with PWR systems. Even though one has no doubt about the safety and the economics of the PHWR`s that are now being operated or constructed in Korea, it is necessary to develop the advanced design technology for even safer and more economical PHWR systems to overcome the ever growing international resistance to sharing of nuclear technology and to meet the even more stringent requirements for the future public acceptance of nuclear power. 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 Fundamental Technologies for Micro Bioreactors  

Science.gov (United States)

This chapter reviews the development of fundamental technologies required for microchip-based bioreactors utilizing living mammalian cells and pressure driven flow. The most important factor in the bioreactor is the cell culture. For proper cell culturing, continuous medium supply from a microfluidic channel and appropriate modification of the channel surface to accommodate cell attachment is required. Moreover, the medium flow rate should be chosen carefully, because shear stress affects cell activity. The techniques presented here could be applied to the development of micro bioreactors such as microlivers, pigment production by plant cells, and artificial insemination.

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

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.

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

Fission Surface Power Technology Development Update  

Science.gov (United States)

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

Tracing Impacts of Science and Technology Development  

Science.gov (United States)

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

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.

Optical glass fiber is a better choice than copper media for supporting both today/tomorrow`s communication network requirements. The optical fiber cable as its final product will play an important role in the high bandwidth superhighway traffic that networks will soon carry. The basic manufacturing technology of fiber optic cables, including its processes and materials, entails the same as that of the conventional copper wire cable, but the performance of the final products is strongly dependent on the details of the cabling designs, materials and processes because the optical fiber is extremely sensitive to environmental conditions. This paper will discuss the technological development of optical fiber cables used in various communication applications.

Hydraulic hammer drilling technology: Developments and capabilities  

Energy Technology Data Exchange (ETDEWEB)

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

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. .

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 of radioisotope preparation and application technology  

International Nuclear Information System (INIS)

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.

Multipurpose prevention technologies: products in development.  

Science.gov (United States)

Multipurpose prevention technologies (MPTs) are broadly defined as products capable of simultaneously addressing multiple sexual and reproductive health needs including unintended pregnancy, STIs including HIV-1, and other reproductive tract infections. MPTs have been discussed for a few decades but little product development has occurred. With the recent proof-of-concept that a topically applied antiretroviral (ARV) can effectively reduce sexual transmission of HIV-1 (tenofovir 1% gel) the impetus to develop MPTs is gaining momentum. Products currently in development are broadly categorized as either long-acting or on-demand. Long-acting MPTs include intravaginal rings (IVRs) and long-acting injectable products. Several IVR MPTs are under development including one designed to release tenofovir to prevent transmission of HIV-1 and levonorgestrel (LNG) to prevent unintended pregnancy over a 90-day period. Another MPT IVR under development is designed to release the ARV dapivirine and LNG for 2 months. Long-acting injectable pre-exposure prophylaxis (PrEP) formulations of rilpivirine (TMC278) and GSK1265744 have entered clinical evaluation and could form the basis of long-acting injectable products for HIV-1 prevention and prevention of unintended pregnancy. On-demand products include TFV 1% gel (HIV-1/HSV-2 prevention), a zinc/carrageenan zinc gel (HIV-1/HSV-2 prevention), and the SILCS diaphragm administered with TFV 1% gel. Significant technical, funding, and regulatory hurdles must be overcome to develop most MPTs; however, the significant reproductive health benefits to many women around the world should provide motivation to overcome these hurdles. This article is based on a presentation at the "Product Development Workshop 2013: HIV and Multipurpose Prevention Technologies", held in Arlington, Virginia on February 21-22, 2013. It forms part of a special supplement to Antiviral Research. PMID:24188708

Development of coated particle fuel technology  

International Nuclear Information System (INIS)

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

Technology development for future thorp reprocessing  

International Nuclear Information System (INIS)

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

Technology development for nuclear material accountability  

International Nuclear Information System (INIS)

A positive on-site verification technique of spent PWR fuel rods in pool and material balance evaluation in bulk material handling facility were developed in support of facility operation and IAEA verification activity. The measured signal from each individual rod in assembly was noticeable different from empty hole and general BKG and also the target rod was not interfered by the surrounding rods in activity counting. Base on this fact it was possible to distinguish the dummy fuel rod from real rod from real one. As a result this technique may be used by IAEA for the on-site routine inspection. A system for facility MUF evaluation was established for the apply it the bulk material handling facility, the evaluated results of MUF occured in CFFF showed that the efficiency of fabrication process and the international confidence level for MUF are considered to have brought forth a positive conclusion. The uncertainty of measurement system in CFFF fell within IAEA's recomended values. But the measurement error limits of DIQ presented to IAEA of CFFF were lower than actual error limits, so that measurement error limits of DIQ might be updated. (Author)

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

Directory of Open Access Journals (Sweden)

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

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.

Key policy considerations for facilitating low carbon technology transfer to developing countries  

International Nuclear Information System (INIS)

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

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

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.

Developments in haul road design technology  

Energy Technology Data Exchange (ETDEWEB)

In surface mining operations, ultra-heavy haul trucks generate axle loads in excess of 200t which are applied to haul roads that have been, at best, empirically designed on the premise of `satisfactory` or `failed`. The use of inappropriate empirical pavement design techniques results in excessive road maintenance and vehicle operating and maintenance costs. There is thus a need for improved technologies to optimise construction and management techniques for unpaved mine haul roads. The aim of this paper is to present developments in haul road design and management which overcome the limitations associated with the previously empirical design techniques. A new mechanistic structural design technique is introduced, following which optimum wearing course material specifications are summarised and a formal approach to road-maintenance management demonstrated. Finally, it is shown how these developments are combined to minimise haulage and road maintenance costs. 6 refs., 5 figs., 2 tabs.

Emerging fermentation technologies: development of novel sourdoughs.  

Science.gov (United States)

The increasing knowledge of sourdough fermentation generates new opportunities for its use in the bakery field. New fermentation technologies emerged through in depth sourdough research. Dextrans are extracellular bacterial polysaccharides produced mainly by lactic acid bacteria (LAB). These bacteria convert sucrose thanks to an inducible enzyme called dextransucrase into dextran and fructose. The structure of dextran depends on the producing micro-organism and on culture conditions. Depending on its structure, dextran has specific properties which lead to several industrial applications in different domains. The use of dextran is not widely spread in the bakery field even if its impact on bread volume and texture was shown. A new process has been developed to obtain a sourdough rich in dextran using a specific LAB strain able to produce a sufficient amount of HMW dextran assuring a significant impact on bread volume. The sourdough obtained permits to improve freshness, crumb structure, mouthfeel and softness of all kinds of baked good from wheat rich dough products to rye sourdough breads. From fundamental research on dextran technology, a new fermentation process has been developed to produce an innovative functional ingredient for bakery industry. PMID:17008159

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 FBR fuel cycle technology in Japan  

International Nuclear Information System (INIS)

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

Risk Management for Human Support Technology Development  

Science.gov (United States)

NASA requires continuous risk management for all programs and projects. The risk management process identifies risks, analyzes their impact, prioritizes them, develops and carries out plans to mitigate or accept them, tracks risks and mitigation plans, and communicates and documents risk information. Project risk management is driven by the project goal and is performed by the entire team. Risk management begins early in the formulation phase with initial risk identification and development of a risk management plan and continues throughout the project life cycle. This paper describes the risk management approach that is suggested for use in NASA's Human Support Technology Development. The first step in risk management is to identify the detailed technical and programmatic risks specific to a project. Each individual risk should be described in detail. The identified risks are summarized in a complete risk list. Risk analysis provides estimates of the likelihood and the qualitative impact of a risk. The likelihood and impact of the risk are used to define its priority location in the risk matrix. The approaches for responding to risk are either to mitigate it by eliminating or reducing the effect or likelihood of a risk, to accept it with a documented rationale and contingency plan, or to research or monitor the risk, The Human Support Technology Development program includes many projects with independently achievable goals. Each project must do independent risk management, considering all its risks together and trading them against performance, budget, and schedule. Since the program can succeed even if some projects fail, the program risk has a complex dependence on the individual project risks.

International Nuclear Information System (INIS)

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

In detail, a fuel rod slitting device is developed for the decladding of the spent fuel. A series of experiments has been performed to find out the optimal condition of the spent fuel voloxidation which converts the UO_2 pellet into U_3O_8 powder. The design requirements of the ACP equipment for hot test is established by analysing the modular requirement, radiation hardening and thermal protection of the process equipment, etc. The prototype of the servo manipulator is developed. The manipulator has an excellent performance in terms of the payload to weight ratio that is 30 % higher than that of existing manipulators. To provide reliability and safety of the ACP, the 3 dimensional graphic simulator is developed. Using the simulator the remote handling operation is simulated and as a result, the optimal layout of ACP is obtained. The supervisory control system is designed to control and monitor the several different unit processes. Also the failure monitoring system is developed to detect the possible accidents of the reduction reactor

Development of a mixed integer programming model for technology development strategy and its application to IGCC technologies  

Energy Technology Data Exchange (ETDEWEB)

The cost effective R and D strategy is required especially for large-scale technologies because their development demands a large amount of investment in general. A mixed integer programming model was developed for the optimum technology development strategy in the field of energy systems. The module of the technology development process in the model is based on GERT (Graphical Evaluation and Review Technique). In the module, a target technology is broken down into many elemental technologies. Usually several target technologies are involved for the evaluation of technology development strategy of one field and some of the elemental technologies are used common to a number of target technologies. Since elemental technologies are explicitly modeled, their spillover effects are necessarily evaluated in this model analysis. The proposed method was applied to the evaluation of the development strategy of four types of IGCC (Integrated coal Gasification Combined Cycle) technologies which have different levels of thermal efficiencies. The total investment on both their R and D and practical use is optimized under the constraint of meeting a certain exogenous scenario of electricity demand. The evaluation results include the optimum additional investment allocation among the development of various elemental technologies; developments of integration technology for IGCC-43%, IGCC-55% and IGCC-48%, coal gasification technology, oxide dispersion strengthened superalloy technology for the gas turbine blade and vane, ceramic matrix composite technology for the gas turbine blade, dry sulfur-removal technology. etc. are cost-effective.

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

Development of advanced LWR fuel pellet technology  

International Nuclear Information System (INIS)

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

Development of the gel pond technology  

Energy Technology Data Exchange (ETDEWEB)

A review of the development of the gel pond technology is presented. First, the emergence and growth of solar pond technology since the 1950's is described. The inherent problems encountered with the conventional salt gradient ponds are discussed, leading to the concept of the solar gel pond in which the salt gradient layer in the former is replaced by a transparent polymer gel. The first phase dealt with the experimental development of a polymer gel which met selection criteria including transmissivity, stability of physical and chemical properties, high viscosity and other physical and optical properties. The gradual development of the polymer gel through an alternating process of testing and elimination and evaluation of relevant properties of the gel has been described. Modeling and optimization studies of the solar gel pond have been presented. Bansal and Kaushik's model for a salt gradient pond has been modified for a solar gel pond, and the results of the simulation are presented in a graphical form to serve as a quick reference for estimation of pond surface area, depth and flow rate for heat extraction depending on the extreme temperature required in the storage zone and the required heat load. Then, a cost-benefit economic analysis compares the economics of a solar gel pond with a conventional salt gradient pond. The construction of an experimental gel pond (18 m/sup 2/) at The University of New Mexico is described, and the results of the study are summarized. Information on commercial scale ponds at Chamberino, New Mexico (110 m/sup 2/), and in Albuquerque, New Mexico (400 m/sup 2/), is provided.

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

Nuclear technology and the developing world  

International Nuclear Information System (INIS)

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

Liquid metal reactor development. Development of LMR design technology  

Energy Technology Data Exchange (ETDEWEB)

This project was performed in five parts, the scope and contents of which are as follows: The nuclear data processing system was established and the KFS group constant library was improved and verified. Basic computation system was constructed by either developing or adding its function. Input/output (I/O) interface processing was developed to establish an integrated calculation system for LMR core nuclear rand thermal-hydraulic design and analysis. An experimental data analysis was performed to validate the constructed core neutronic calculation system. Using the established core calculation system and design technology, preliminary core design and performance analysis on the domestic LMR core design concept were carried out. To develop the basic technology of the LMR system analysis, LMR system behavior characteristics evaluation, thermal -fluid system analysis in the reactor pool, preliminary overall plant analysis and computer codes development have been performed.

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

Large rotorcraft transmission technology development program  

Science.gov (United States)

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

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).

Development of solid oxide fuel cell technology  

International Nuclear Information System (INIS)

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

Developments in resid cracking technology at Gulf  

Energy Technology Data Exchange (ETDEWEB)

As conservation measures and standards for new car efficiencies take hold, the demand for gasoline is expected to decline, forcing refiners to meet product demands efficiently with minimum crude. With a reduced market and relatively low price for residual streams, it is very likely that fluid catalytic cracking (FCC) will continue to play a key role in upgrading resids. The economics are overwhelmingly in favor of this strategy. With current price differentials between asphalt and FCC products, the incremental profit for resid cracking at one Gulf Refinery was estimated to be $8/bbl of vacuum tower bottoms cracked. Processing resids poses a number of problems, however. They often contain high levels of sulfur, metals, and coke precursors which may require high catalysts costs, unit modifications and process innovations. Development of promising approaches to handling resids has focused on three key area: 1)catalyst and passivator technology improvemnts; 2)innovations in FCC processing technology; and 3)coupling FCC with other processes. The report presented reviews Gulf's research efforts in these areas. In addition, Gulf's commercial and pilot plant resid cracking data are discussed. (JMT)

Safeguards technology research and development at CIAE  

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)

Development of decommissioning system engineering technology  

International Nuclear Information System (INIS)

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

Development of Coated Particle Fuel Technology  

International Nuclear Information System (INIS)

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

Technology Development Risk Assessment for Space Transportation Systems  

Science.gov (United States)

A new approach for assessing development risk associated with technology development projects is presented. The method represents technology evolution in terms of sector-specific discrete development stages. A Monte Carlo simulation is used to generate development probability distributions based on statistical models of the discrete transitions. Development risk is derived from the resulting probability distributions and specific program requirements. Two sample cases are discussed to illustrate the approach, a single rocket engine development and a three-technology space transportation portfolio.

Development of a Remote Monitoring System Using Meteor Burst Technology  

International Nuclear Information System (INIS)

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

A status report:. FACT - a fact!  

Science.gov (United States)

In the past years, the second generation of imaging air-Cherenkov telescopes has proven its power detecting weak sources with high sensitivity and low energy threshold. The goal to further improve the sensitivity and lower the energy threshold requires a robust and hlghly efficient sensor technology. A promising detector technology are silicon based photon detectors, namely Geiger-mode avalanche photo-diodes (G-APDs). They promise robustness and easy manage-ability compared photo-multiplier tubes so far in use. To prove the applicability of this technology for Cherenkov telescopes, one of the former HEGRA telescopes was revived and equipped with a camera using G-APDs all photo sensors. Since G-APDs are comparably small, solid light guides are used to significantly increase the light collection area of each sensor. With this technologies, the First G-APD Cherenkov Telescopes (FACT) promises an increase in sensitivity and decrease in energy threshold, compared with a classical photo-multiplier based camera.

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

Westinghouse gasification technology development and projects status  

Energy Technology Data Exchange (ETDEWEB)

A joint program between Westinghouse, the Department of Energy, and the Gas Research Institute has shown, through the use of a 35 ton-per-day coal feed process development unit (PDU), that the fluidized bed gasifier is technically feasible and economically attractive. The process has been shown to be simple, controllable, and safe in converting many types of coals, including reactive western coals, caking eastern coals, high ash coals, and run-of-mine coals. The process is efficient because it utilizes many coals at high conversion efficiency with relatively low use of oxidant and steam. Because of its simplicity, its use of available hardware technology, and the absence of tars in the product gas, the system has low capital and operating costs. It can be employed with little adverse environmental impact because of its efficiency, low
