The history of the IEA volume II: major policies and actions

International Nuclear Information System (INIS)

Scott, R.

1995-01-01

Volume II of the History of the International Energy Agency (IEA) continues the story which began with the Origins and Structure of the Agency in Volume I. After examining the industrial countries'energy policies leading up to the 1973-1974 crisis, the current Volume focuses on the new policies adopted in the IEA during its first twenty years.The first part of this book deals with a section on 'Energy Policy Origins of the 1973-1974 Oil Supply Vulnerability : The Optimistic-Passive Approach to Oil Policy'. The main events and developments leading up to the crisis are briefly outlined together with a short presentation of the policy views and critical conclusions that were made on that situation by some of the most knowledgeable oil specialists of the period. The second part surveys IEA oil security, beginning with the oil Emergency Sharing System. The IAE's long-term policies for reducing its Members'dependence on imported oil are the subject of the third part. In this part is described the development of some of the leading IEA work in the field of energy and the environment, the Agency's far-reaching reviews of Members'policies in this sector and a discussion of the 'free markets' policy and of the IEA Shared Goals of 1993. The fourth part deals with the still longer-term Energy Research and Development in the IEA and is a review of the internal organization of IEA work in the R and D field. The fifth part follows with a discussion of the Oil Market policies and practices of the Agency, where the main and durable goals are 'transparency and information dissemination'. The last part addresses the Agency's policies and actions with respect to Co-operation with Non-Member Countries. Then, it takes up Members'policies and activities in connection with the oil producer and consumer country dialogue of 1976-1977 and outlines its disappointing outcome. (O.L.). 2 figs., 13 tabs

IEA Energy Training Capacity-building Programme

2009-07-01

The IEA has carried out training activities in energy-related areas from its origins as an agency, with the Emergency Response Exercises (ERE), designed to prepare member countries for oil supply disruption through a set of specially prepared drills simulating crisis conditions. The globalisation of world energy markets in recent years and the wider engagement of the IEA beyond its members have expanded this role, as demand for training instruction has increased. In response, the IEA has created the Energy Training and Capacity-Building Programme, which, through seminars and workshops, secondments and internships, will offer training in the methods and standards that make IEA work in a wide range of energy-related areas, including statistics, the international standard for objective policy recommendations.

How the nuclear safety team conducts emergency exercises at the IEA-R1 reactor

This work introduces the Diagram of Emergency Exercise Coordination designed by the Nuclear Safety Team for better Emergency Exercise coordination. The Nuclear Safety Team was created with the mission of avoiding, preventing and mitigating the causes and effects of accidents at the IEA-R1. The facility where we conduct our work is located in an area of a huge population, what increases the responsibility of our mission: conducting exercises and training are part of our daily activities. During the Emergency Exercise, accidents ranked 0-4 on INES (International Nuclear Events Scale) are simulated and involve: Police Department, Fire Department, workers, people from the community, and others. In the last exercise held in June 2014, the scenario contemplated a terrorist organization action that infiltrated in a group of students who were visiting the IEA-R1, tried to steal fresh fuel element to fabricate a dirty bomb. Emergency procedures and plans, timeline and metrics of the actions were applied to the Emergency Exercise evaluation. The next exercise will be held in November, with the simulation of the piping of the primary cooling circuit rupture, causing the emptying of the pool and the lack of cooling of the fuel elements in the reactor core: this will be the scenario. The skills acquired and the systems improvement have been very important tools for the reactor operation safety and the Nuclear Safety Team is making technical efforts so that these Emergency Exercises may be applied to other nuclear and radiological facilities. Equally important for the process of improving nuclear safety is the emphasis placed on implementing quality improvements to the human factor in the nuclear safety area, a crucial element that is often not considered by those outside the nuclear sector. Surely, the Diagram of Emergency Exercise Coordination application will improve and facilitate the organization, coordination and evaluation tasks. (author)

Renewable energy. Market and policy trends in IEA countries

International Nuclear Information System (INIS)

2004-01-01

Renewable energy has received high levels of attention in recent years as an alternative to traditional hydrocarbons. Governments, industry and consumers have adopted and promoted renewable technologies in response to concerns about energy security and the environment, and as a solution to electricity access problems in developing countries. To what degree has renewable energy gained a share in the energy mix? What lessons can be learned from efforts made thus far? Renewable Energy - Market and Policy Trends in IEA Countries reviews the experience of IEA countries after the oil crisis in the 1970's initiated a surge of investments in renewables research and development. While use of renewables has grown rapidly, they still account for only a small portion of the IEA energy mix. Hydropower, bio-energy and geothermal energy are mature technologies that contribute about 5 - 6% to primary energy supply. Solar, wind, and other new renewables have experienced rapid technology development, but as yet they represent only a small share. This work examines policies and measures that have been introduced in IEA countries to increase the cost effective deployment of renewables, reviews the objectives behind these policies, and evaluates the results. The aim is to identify best practices in order to assist governments in making future policy decisions

This paper presents a preliminary RELAP5 model for the IEA-R1 core. The power distribution is supplied by the neutronic code, CITATION. The main objective is to model the IEA-R1 core and validate the model through the comparison of the results to the ones from COBRA and PARET, which were used in the Final Safety Analysis Report (FSAR) for this plant. Preliminary calculations regarding some simulations are presented. Boundary conditions are simulated through time dependent components. Results obtained are compared to those available for the IEA-R1. This study will be continued considering a model for the whole plant. Important transient and accidents will be analysed in order to verify the Emergency Core Cooling System - ECCS efficiency to hold its function as projected to preserve the integrity of the reactor core and guarantee its cooling.

Shared Governance and Work Engagement in Emergency Nurses.

Science.gov (United States)

Siller, Jennifer; Dolansky, Mary A; Clavelle, Joanne T; Fitzpatrick, Joyce J

2016-07-01

Lack of work engagement in emergency nurses has been linked to increased job turnover, burnout, and lack of job satisfaction. Shared governance is a vehicle that can be used by emergency nursing leaders to increase work engagement among emergency nurses. Research is lacking about the relationship between perceptions of shared governance and work engagement in emergency nurses. In this study we examined the relationship between ED nurses' perceptions of shared governance and work engagement. A descriptive correlation design was used with a convenience sample of 43 emergency nurses recruited through the ENA Web site. Participants completed a demographic questionnaire, the Index of Professional Nursing Governance Tool, and the Utrecht Work Engagement Scale. The mean total work engagement score indicated average engagement (M = 4.4, standard deviation = 1.2). A significant positive relationship was found between shared governance and work engagement, indicating that as perceptions of shared governance increase, work engagement increases (r (41) = 0.62, P emergency nurses. Understanding the relationship between perceptions of shared governance and work engagement in emergency nurses may assist emergency nursing leaders in developing and testing interventions to enhance it.

This publication provides a detailed look at the specific systems in the United Kingdom for responding to an oil supply crisis. In 2007, the IEA published ''Oil Supply Security: Emergency Response of IEA Countries''. Rather than waiting for the completion of the current review cycle to renew this full publication, the IEA will provide updates to the country chapters as these become available following the specific country's review. The aim of series of publications is to provide an overview of the IEA oil emergency response system and a detailed look at the specific systems in each IEA country for responding to an oil supply crisis. The 2007 publication represented the findings of a five year review cycle of the emergency response mechanisms in IEA member countries. Since the 2007 publication, the IEA has started a new cycle of reviews which now includes reviewing gas emergency policies.

Full Text Available It is commonly claimed that assessing the effectiveness of International Environmental Agreements (IEAs from the environmental problem-solving perspective is challenging because environmental data are not available. However, not much research has been done on the characterization of the nature and causes of such data unavailability. This article analyzes the term “data unavailability” and provides three typologies for data unavailability: (a “true unavailability,” where data collection complexities and resource constraints limit data collection and analysis; (b “false unavailability,” which refers to the existence of relevant data, but failure to report due to various causes; and (c “external availability,” which refers to the existence of relevant data in several organizations and research institutions, but with no established networks for data sharing between such institutions and the IEA institutions. This article discusses the causes for the various types of data unavailability and makes recommendations for promoting data availability.

This new edition of 'Findings of recent IEA work' provides a sample of the Agency's activities since its 2005 Ministerial meeting. Each page focuses on a specific subject or project, including references to IEA work that will be of use to governments, academics, journalists and the wider public. This volume is not all-inclusive, but seeks to highlight IEA efforts to respond to the concerns of its member countries and identify ways to overcome the energy challenges we face. Since the last meeting of IEA energy ministers in May 2005, the global energy picture has changed. The challenges of energy security and climate change have moved higher on the agenda. To this end, the IEA ministers and the G8 have asked the IEA to make concrete recommendations to achieve a 'clean, competitive and clever energy future'. Energy efficiency is a vital first step, but strong commitment to research, development and deployment of technology is essential for the longer term. Some specific topics reported included are: Coal: responding to the challenges; CO{sub 2} emissions from fuel combustion; Emissions trading for climate policy; CO{sub 2} capture and storage technologies; Russian energy policy developments; and Coal in China.

This present work describes the development program carried out in the design and construction of the Emergency Core Cooling System for the IEA-R1m Research Reactor, including the system design, the experiments performed to validate the design, manufacturing, installation and commissioning. The experiments were performed in two phases. In the first phase, the spray flow rate and distribution were measured, using a full scale mock-up of the entire core, to establish the spray header geometry and specifications. In the second phase, a test section was fitted with electrically heated plates to simulate the fuel plates. Temperature measurements were carried out to demonstrate the effectiveness of the system to keep the temperatures below the limiting value. The experimental results were shown to the licensing authorities during the certification process. The main difficulties during the system assembly are also described. (author)

1988-01-01

A multinational program of cooperative research, development, demonstrations, and exchanges of information on superconducting magnets for fusion was initiated in 1977 under an IEA agreement. The first major step in the development of TF magnets was called the Large Coil Task. Participants in LCT were the U.S. DOE, EURATOM, JAERI, and the Departement Federal de l'Interieur of Switzerland. The goals of LCT were to obtain experimental data, to demonstrate reliable operation of large superconducting coils, and to prove design principles and fabrication techniques being considered for the toroidal magnets of thermonuclear reactors. These goals were to be accomplished through coordinated but largely independent design, development, and construction of six test coils, followed by collaborative testing in a compact toroidal test array at fields of 8 T and higher. Under the terms of the IEA Agreement, the United States built and operated the test facility at Oak Ridge and provided three test coils. The other participants provided one coil each. Information on design and manufacturing and all test data were shared by all. The LCT team of each participant included a government laboratory and industrial partners or contractors. The last coil was completed in 1985, and the test assembly was completed in October of that year. Over the next 23 months, the six-coil array was cooled down and extensive testing was performed. Results were gratifying, as tests achieved design-point performance and well beyond. (Each coil reached a peak field of 9 T.) Experiments elucidated coil behavior, delineated limits of operability, and demonstrated coil safety. (orig./KP)

Progress Implementing the IEA 25 Energy Efficiency Policy Recommendations

2012-07-01

Significantly improving energy efficiency remains a priority for all countries. Meetings of G8 leaders and IEA ministers reaffirmed the critical role that improved energy efficiency can play in addressing energy security, environmental and economic challenges. Many IEA publications have also documented the essential role of energy efficiency. For example, the World Energy Outlook and the Energy Technology Perspectives reports identify energy efficiency as the most significant contributor to achieving energy security, economic and environmental goals. Energy efficiency is clearly the “first fuel” in the delivery of energy services in the coming low-carbon energy future. To support governments in their implementation of energy efficiency, the IEA recommended the adoption of specific energy efficiency policy measures to the G8 summits in 2006, 2007 and 2008. The consolidated set of recommendations to these summits is known as the ‘IEA 25 energy efficiency policy recommendations’ because it covers 25 fields of action across seven priority areas: cross-sectoral activity, buildings, appliances, lighting, transport, industry and energy utilities. The IEA estimates that if implemented globally without delay, the proposed actions could save as much as 7.6 giga tonnes (Gt) CO2/year by 2030 – almost 1.5 times the current annual carbon dioxide (CO2) emissions of the United States. The IEA 25 energy efficiency policy recommendations were developed to address policy gaps and priorities. This has two implications. First, the recommendations do not cover the full range of energy efficiency policy activity possible. Rather, they focus on priority energy efficiency policies identified by IEA analysis. Second, while IEA analysis, the energy efficiency professional literature and engagement with experts clearly demonstrate the broad benefits of these IEA priority measures, the recommendations are not weighted to reflect the different energy end-use make up of different

In 2010, the International Energy Agency (IEA) and the Nuclear Energy Agency (NEA) released a Nuclear Energy Technology Road-map which outlined the steps needed to accelerate the development of nuclear power and its role in achieve deep greenhouse-gas emissions reduction. Both the global energy sector and the outlook for nuclear have changed significantly since then and an update of this Road-map is currently underway. The IEA and NEA held a stakeholder dialogue meeting focused on nuclear develop in Asia on 25 February 2014 in Hong Kong. The meeting brought together key stakeholders from industry, government, finance and other relevant organisations from Asia and beyond to help define and prioritise key items to be discussed in the IEA/NEA's Nuclear Road-map Update. One of the expected outcomes of this intensive brainstorming and Road-map development session was to discus key targets, milestones, policy measures and other actions needed to support the development and deployment of nuclear power. The workshop was organized in 3 sessions dealing with: Session 1 - Technology development needs for nuclear (Reactor technology, Fuel cycle and decommissioning); Session 2 - Breakout Discussion: - Group I: Financing nuclear. This session focussed on today's reality for financing nuclear and the current economics of nuclear. Mechanisms such as government loan guarantees, vendor financing and role of export credit agencies were discussed. Participants were asked to share lessons learnt and current practices on financing nuclear as well as recommendations (if needed) for additional policy support or changes in technology development (e.g. SMR) which would facilitate greater deployment of nuclear technologies. - Group II: Nuclear regulation and safety. This session focussed on regulatory needs for enhanced security and regulation for new build programmes, institutional development requirements for new nuclear countries.

Shared cross-modal associations and the emergence of the lexicon

OpenAIRE

Cuskley, Christine F.

2013-01-01

This thesis centres around a sensory theory of protolanguage emergence, or STP. The STP proposes that shared biases to make associations between sensory modalities provided the basis for the emergence of a shared protolinguistic lexicon. Crucially, this lexicon would have been grounded in our perceptual systems, and thus fundamentally non-arbitrary. The foundation of such a lexicon lies in shared cross-modal associations: biases shared among language users to map properties in ...

Innovation in the energy sector: Lessons learnt from R and D expenditures and patents in selected IEA countries

International Nuclear Information System (INIS)

Bointner, Raphael

2014-01-01

Long time series of the IEA and international patent offices offer a huge potential for scientific investigations of the energy innovation process. Thus, this paper deals with a broad literature review on innovation drivers and barriers, and an analysis of the knowledge induced by public research and development expenditures (R and D) and patents in the energy sector. The cumulative knowledge stock induced by public R and D expenditures in 14 investigated IEA-countries is 102.3 bn EUR in 2013. Nuclear energy has the largest share of 43.9 bn EUR, followed by energy efficiency accounting for 14.9 bn EUR, fossil fuels with 13.5 bn EUR, and renewable energy with 12.1 bn EUR. A regression analysis indicates a linear relation between the GDP and the cumulative knowledge, with each billion EUR of GDP leading to an additional knowledge of 3.1 mil EUR. However, linearity is not given for single energy technologies. Further, the results show that appropriate public R and D funding for research and development associated with a subsequent promotion of the market diffusion of a niche technology may lead to a breakthrough of the respective technology. - Highlights: • The cumulative energy knowledge stock in 14 IEA-countries is 102.3 bn EUR in 2013. • Each billion EUR of GDP lead to an additional knowledge of 3.1 mil EUR. • Medium IEA-countries may compete with large ones by promoting a niche strategy. • Patent knowledge grew 5.9 times in medium and 5.6 in large IEA-countries since 1990

The IEA Model of Short-term Energy Security

Energy Technology Data Exchange (ETDEWEB)

NONE

2011-07-01

Ensuring energy security has been at the centre of the IEA mission since its inception, following the oil crises of the early 1970s. While the security of oil supplies remains important, contemporary energy security policies must address all energy sources and cover a comprehensive range of natural, economic and political risks that affect energy sources, infrastructures and services. In response to this challenge, the IEA is currently developing a Model Of Short-term Energy Security (MOSES) to evaluate the energy security risks and resilience capacities of its member countries. The current version of MOSES covers short-term security of supply for primary energy sources and secondary fuels among IEA countries. It also lays the foundation for analysis of vulnerabilities of electricity and end-use energy sectors. MOSES contains a novel approach to analysing energy security, which can be used to identify energy security priorities, as a starting point for national energy security assessments and to track the evolution of a country's energy security profile. By grouping together countries with similar 'energy security profiles', MOSES depicts the energy security landscape of IEA countries. By extending the MOSES methodology to electricity security and energy services in the future, the IEA aims to develop a comprehensive policy-relevant perspective on global energy security. This Working Paper is intended for readers who wish to explore the MOSES methodology in depth; there is also a brochure which provides an overview of the analysis and results.

In response to threats posed to the future supply of energy and to the environment, the G8 leaders, in Gleneagles, UK in 2005, agreed to an initiative called the Gleneagles Plan of Action (GPOA) which addresses climate change, clean energy and sustainable development. In the GPOA, G8 leaders pledged to encourage the development of cleaner, more efficient and lower-emitting vehicles, and to promote their deployment by, among other means, asking the IEA to review existing standards and codes for vehicle efficiency and to identify best practices. In order to properly response to the above-mentioned requests from G8 leaders, the IEA has launched, among other activities, study on policies for 'transforming the way we use energy' focusing on end-use efficiency including the one in transport sector and made a comprehensive response to the GPOA at the 2008 G8 Summit Meeting in Japan with 25 recommendations on energy efficiency. Regarding these recommendations, the G8 leaders have proclaimed, in the G8 Hokkaido Toyako Summit Leaders Declaration, that they would maximize implementation of the IEA's 25 recommendations. This paper summarizes the IEA activities in transport sector regarding the GPOA and their findings and recommendations.

A Look at the IEA 2011 Release of Strategic Oil Reserves

International Nuclear Information System (INIS)

Glick, Devin

2011-07-01

On June 23, 2011, the International Energy Agency (IEA) coordinated the release of 60 million barrels of emergency stocks in response to the disruption of oil production in Libya due to civil unrest. This announcement elicited a mixed reaction from the public and from the market. Some politicians in the United States called the move a political decision by the President to satisfy voters, private oil companies did not like the interference, and some OPEC countries were upset and called the release unnecessary. The reason why there was a strong reaction was because the IEA had never coordinated a release in this manner before. It was only the third time there had ever been a release, after the First Gulf War in 1991 and for Hurricane Katrina and Rita in 2005. The circumstance and decision for the June 23 drawdown was more flexible and may signal a change in the way strategic petroleum stocks are used. This paper examines the motivations and the potential consequences of the International Energy Agency's coordinated action to release petroleum stocks on June 23, 2011. (author)

Nuclear facilities must monitoring radiation levels to establish procedures for radiological protection staff involving workers and the public. The Instituto de Pesquisas Energeticas e Nucleares - IPEN has 5 important plants and in case of accident in one of them, the Institute keeps operational an Emergency Response Plan (ERP). This document (ERP) is designed to coordinate all procedures to assure safe and secure conditions for workers, environment and the public. One of this plants is the IEA-R1 reactor, it is the oldest nuclear research reactor (pool type) in Latin America, reached it first criticality in September of 1957. The reactor is used 60 hours/week with continuous operation and with nominal power of 3.5 MW, with technical conditions to operate at 5 MW thermal power. This reactor has a Radiological Emergency Plan that establishes the implementation of rules for workers and people living at the exclusion area in the case of an emergency situation. This paper aims to describe the implementation of a computational system developed for remote radiation monitoring, in a continuous schedule of IEA-R1 nuclear research reactor containment building. Results of this action can be used as a support mean in a radiological emergency. All necessary modules for radiation detection, signals conditioners and processing, data acquisition board, software development and computer specifications are described. The data acquisition system operating in the reactor shows readings concerned to radiation environment such as activity, doses and concentration in real time and displays a periodical data bank (Data Base) of this features allowing through the surveillance of the operation records anytime, leading to studies and analysis of radiation levels. Results of this data acquisition are shown by means of computer graphics screens developed for windows environment using Visual Basic software. (author)

Improving emergency management through shared information processing - considerations in Emergency Operations Center design

International Nuclear Information System (INIS)

DeBusk, R.E.; Walker, J.A.

1987-01-01

An Emergency Operations Center (EOC) is a shared information processing facility. Although seemingly obvious, many EOCs are designed and operated based on other criteria. The results, measured in terms of response effectiveness, are difficult to determine. A review of some recent disasters reveals a pattern of poor performance for the EOCs involved. These conclusions are tentative because so little research has been done on the design, operation, or evaluation of emergency operations centers. The EOC is not an onsite response command post but a facility removed from the response where tactical and strategic decisions are made based on information from the response site and elsewhere. The EOC is therefore the central focus of emergency information processing and higher-level decision making. Examining existing EOCs, several common functions emerge. These functions can be described in terms of shared information processing. However, many factors impact the design and operation of EOCs. Politics, budgets, and personal ambition are only a few such factors. Examining EOC design and operation in terms of shared information processing operationalized in the seven principal functions within the EOC provides a framework for establishing principles of EOC design and operation. In the response to emergencies such as Bhopal or Chernobyl the stakes are high. Applying new techniques and technologies of management systems can improve the probability of success. This research is a beginning step - to understand how EOCs function, to define the system. Predictive or prescriptive analysis must wait until sufficient empirical data is available to complete a descriptive model for EOC operations

Energy policies of IEA countries: Austria - 2007 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-03-15

Since the last review in 2002, Austrian energy policy has seen many positive developments. Today, Austria counts among the IEA member countries with the highest share of renewable energy supply, thus increasing energy security and reducing CO2 emissions. Great progress has also been made in the utilisation of biomass for heat and electricity production. Nevertheless, many challenges remain. The climate strategy revision in 2007 is commendably realistic, but uncertainty remains whether it will be sufficient, and whether renewables and energy efficiency are well-balanced within it. While Austria is strongly promoting an increase of renewables production by adopting challenging targets, it is less ambitious in the area of energy efficiency. To achieve the renewables target, their supply will have to double, leading to significant increases in costs. In energy efficiency, while Austria is leading in developing efficient building solutions, there are concerns about implementation, especially about the lack of ambition and divergence in building codes. Overall, energy intensity has increased in recent years, and the government will have to put a strong focus on reversing this development. Despite the early opening of the energy markets, effective competition has failed to emerge. This is partially due to systemic weaknesses such as dominant incumbents, lack of transparency in price formulation and a weak regulatory system with the potential for conflicts of interest. This review thoroughly analyses Austrian energy policy and identifies the key challenges that need to be addressed. With recommendations for improvements, it is an important guide for Austrian policy makers toward a safer and cleaner energy future.

The 2007 natural gas market review of the International energy agency (IEA) is this year subtitled: 'security in a globalizing market to 2015'. The review thus stresses on the 2006 highlights but reinforces the idea already expressed in the 2006 issue that energy security is now an inevitable topic. It offers also a prospective analysis of the natural gas market up to 2015 and devotes a full chapter to LNG development. As a matter of fact, the IEA considers that, from now to 2015, two thirds of the additional gas supplies will be in the form of LNG. The review supplies also some complements about some national markets. The present article reviews the most important points of this analysis. (J.S.)

The conference was attended by 258 participants. During the conference, the future visions for photovoltaics from both country and industry perspectives were presented and discussed. National issues and needs with respect to grid-connected and stand-alone PV systems were discussed. International issues and future visions were examined. Asian countries presented their current status and experience with the market introduction of photovoltaics. Photovoltaics and its opportunities within the framework of international institutions, namely the IEA, the International Finance Corporation (IFC) and the Clean Development Mechanism (CDM) were addressed, as were the needs of the most important markets - namely for distributed grid-connected applications and rural electrification in developing countries. A round-table discussion was also held on the future role and missions of the PVPS programme.

China will play a positive role in the global development of gas, the International Energy Agency’s (IEA) Executive Director, Maria Van der Hoeven has said in Beijing on 11 September, 2012 when launching a new IEA report: Gas Pricing and Regulation, China’s challenges and IEA experiences. In line with its aim to meet growing energy demand while shifting away from coal, China has set an ambitious goal of doubling its use of natural gas from 2011 levels by 2015. Prospects are good for significant new supplies – both domestic and imported, conventional and unconventional – to come online in the medium-term, but notable challenges remain, particularly concerning gas pricing and the institutional and regulatory landscape. While China’s circumstances are, in many respects unique, some current issues are similar to those a number of IEA countries have faced. This report highlights some key challenges China faces in its transition to greater reliance on natural gas, then explores in detail relevant experiences from IEA countries, particularly in the United Kingdom, the Netherlands, and the United States as well as the European Union (EU). Preliminary suggestions about how lessons learned in other countries could be applied to China’s situation are offered as well. The aim of this report is to provide stakeholders in China with a useful reference as they consider decisions about the evolution of the gas sector in their country.

For the first time, the IEA has reviewed the energy policies of the European Union which shape the energy use of almost 500 million citizens in 27 EU member countries. A unique entity governed under complex and almost constantly evolving structures, the EU constitutes a challenge for energy policy makers. Its energy policy has a global impact, not only because of its 16% share of world energy demand, but also because of the EU leadership in addressing climate change. Strong policy drives are underway in the EU to achieve the completion of the internal energy market, increase renewable energy supply, reduce CO2 emissions and make the EU more energy-efficient. Concerns about security of supply have also led to a greater focus on improved energy relations with supplier countries, and new institutional structures are being put in place. How much progress has been made in the field of security, internal market and external energy policies? And in which of these areas has the EU already implemented a fully integrated policy? IEA Energy Policies Review: The European Union - 2008 addresses these questions and also analyses the impact of the most recent major EU policy measures, in particular the Energy & Climate Package of January 2008 and the 3rd Liberalisation Package of September 2007. This book finds that both of these proposals are highly ambitious. But implementing them and reviewing both volume and allocation of energy R&D will be necessary to achieve a sustainable energy future in a fully competitive integrated EU energy market.

Bower, Ward

1999-01-01

The International Energy Agency (IEA) is an energy forum for 24 industrialized countries and was established in 1974 as an autonomous body within the Organization for Economic Cooperation and Development (OECD). The IEA Photovoltaic Power Systems (PVPS) program implementing agreement was signed in 1993, and renewed for another five years in 1998. Twenty-two countries are collaborating under the auspices of the IEA in the PVPS to address common technical and informational barriers that often limit the rate at which photovoltaic technologies advance into the markets. Task V of the IEA PVPS is entitled ''Grid Interconnection of Building-Integrated and Other Dispersed Photovoltaic Power Systems.'' The task sponsored a workshop in September 1997 on grid-interconnection of photovoltaic systems and is planning a second workshop to address impacts of more penetration of dispersed systems into the utility grid. This paper will summarize the accomplishments of Task V over the last five years and will detail the planned work for the next three years

Energy policies of IEA countries. Canada 1996 review

International Nuclear Information System (INIS)

1996-01-01

This IEA report provides a comprehensive, in-depth assessment of the energy policies of Canada, including recommendations on future policy developments. The report acknowledges the marked shift of federal energy policy in the last decade away from heavy intervention to a more market-based approach. This has increased the strength and competitive position of Canada's energy producers, especially in oil and gas, and has provided more choice for consumers. Electricity, however, is an area that could benefit from a more market-based policy orientation. Federal provincial co-ordination is of fundamental importance. Other key issues highlighted in the review include the opportunities and challenges of international agreements on the environment, which increasingly drive energy policy decision-making; the adequacy and effectiveness of programmes to promote energy efficiency; and the balance and direction of energy research and development efforts. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author)

Emerging Geospatial Sharing Technologies in Earth and Space Science Informatics

Emerging Geospatial Sharing Technologies in Earth and Space Science Informatics The Open Geospatial Consortium (OGC) mission is to serve as a global forum for the collaboration of developers and users of spatial data products and services, and to advance the development of international standards for geospatial interoperability. The OGC coordinates with over 400 institutions in the development of geospatial standards. In the last years two main trends are making disruptions in geospatial applications: mobile and context sharing. People now have more and more mobile devices to support their work and personal life. Mobile devices are intermittently connected to the internet and have smaller computing capacity than a desktop computer. Based on this trend a new OGC file format standard called GeoPackage will enable greater geospatial data sharing on mobile devices. GeoPackage is perhaps best understood as the natural evolution of Shapefiles, which have been the predominant lightweight geodata sharing format for two decades. However the format is extremely limited. Four major shortcomings are that only vector points, lines, and polygons are supported; property names are constrained by the dBASE format; multiple files are required to encode a single data set; and multiple Shapefiles are required to encode multiple data sets. A more modern lingua franca for geospatial data is long overdue. GeoPackage fills this need with support for vector data, image tile matrices, and raster data. And it builds upon a database container - SQLite - that's self-contained, single-file, cross-platform, serverless, transactional, and open source. A GeoPackage, in essence, is a set of SQLite database tables whose content and layout is described in the candidate GeoPackage Implementation Specification available at https://portal.opengeospatial.org/files/?artifact_id=54838&version=1. The second trend is sharing client 'contexts'. When a user is looking into an article or a product on the web

IEA joint action. Aerodynamics of wind turbines

Energy Technology Data Exchange (ETDEWEB)

Maribo Pedersen, B. [ed.

1997-12-31

In the period 1992-1997 the IEA Annex XIV `Field Rotor Aerodynamics` was carried out. Within its framework 5 institutes from 4 different countries participated in performing detailed aerodynamic measurements on full-scale wind turbines. The Annex was successfully completed and resulted in a unique database of aerodynamic measurements. The database is stored on an ECN disc (available through ftp) and on a CD-ROM. It is expected that this base will be used extensively in the development and validation of new aerodynamic models. Nevertheless at the end of IEA Annex XIV, it was recommended to perform a new IEA Annex due to the following reasons: In Annex XIV several data exchange rounds appeared to be necessary before a satisfactory result was achieved. This is due to the huge amount of data which had to be supplied, by which a thorough inspection of all data is very difficult and very time consuming; Most experimental facilities are still operational and new, very useful, measurements are expected in the near future; The definition of angle of attack and dynamic pressure in the rotating environment is less straightforward than in the wind tunnel. The conclusion from Annex XIV was that the uncertainty which results from these different definitions is still too large and more investigation in this field is required. (EG)

The need for combining IEA and IE tools. The potential effects of a global ban on PVC on climate change

2008-01-01

Over the last decades the concepts of Integrated Environmental Assessment (IEA) and Industrial Ecology (IE), both claiming to provide analyses and solutions for sustainability issues, have been developed separately as they emerged in response to questions from different policy-fields. In both fields, specific tools are used to support national and international environmental policy. The focus of IEA and IE tools, however, is different. IEA tools focus on one or a limited number of specific environmental issues. They often model the chain environmental processes with high spatial (and temporal) resolution, but have a low resolution for the material structure of the economy and only partly take into account indirect effects that occur via physical and socio-economic linkages. IE tools take into account all environmental issues related to a specific substance or product. They have a high resolution for the material structure of the economy and take into account indirect effects that occur via physical linkages, however, their environmental modelling is very limited. Both IE and IEA tools have proven to be very useful and neither is superior to the other. However, a combination of both can provide additional information that can be used for more effective policy making. We use the case of a hypothetical world-wide ban on PVC to show that a measure that is not directly related to climate change could still have significant climate effects. This indirect effect is a result of the linkages of material flows in society. We show that IEA tools are not well suited to include these types of effects and that IE tools can fill this gap partially. What is really needed is a broader systems perspective that takes into account the full range of possible side-effects of environmental policy measures. (author)

This presentation will provide an overview of progress to date in the development of a system modeling framework and ontology for wind turbines and plants as part of the larger IEA Wind Task 37 on wind energy systems engineering. The goals of the effort are to create a set of guidelines for a common conceptual architecture for wind turbines and plants so that practitioners can more easily share descriptions of wind turbines and plants across multiple parties and reduce the effort for translating descriptions between models; integrate different models together and collaborate on model development; and translate models among different levels of fidelity in the system.

IEA is concerned by the costs of the energy transition in Germany

2013-01-01

Last May the International Energy Agency (IEA) published an analysis of the energy transition in Germany. This analysis acknowledges the efforts made by Germany for a better energy efficiency and for the important development of renewable energies but also highlights 3 concerns. First, the cost for the energy transition is not fairly dispatched: electrical power is far more expensive for households than for enterprises. Secondly, according to the IEA, measures must be taken to restrain the growing costs of renewable energies and to foster investment to develop smart grids. Thirdly, the IEA misses the lack of coordination of Germany's energy policy with foreign countries' ones as German decisions have an impact beyond its frontiers. (A.C.)

Energy policies of IEA countries. Sweden 1996 review

International Nuclear Information System (INIS)

1996-01-01

This IEA report provides a comprehensive, in-depth assessment of the energy policies of Sweden, including recommendations on future policy developments. Electricity is a focal point of Sweden's energy policy. After a shift in the energy mix to favour electricity in the early 1970's, nuclear and hydro power each make up about half of the electricity supply. Two key events have occurred since then: the 1980 referendum, which calls for the phase-out of all nuclear plants by 2010; the recent restructuring and liberalization of the electricity sector with the creation of a Nordic electricity market. In this context, the report argues the case for making a decision now on the nuclear issue to clarify Sweden's electricity future. Other key issues highlighted in the report include Sweden's use of economic policy instruments such as a carbon tax to achieve energy and environment goals, and the adequacy and effectiveness of government efforts to promote biofuels and energy efficiency. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author). 13 figs., 9 tabs., 4 appends

A partial replacement of the IEA-R1 piping system was conducted in 2014. The aim of this work is to perform the stress analysis of the renewed primary piping system of the IEA-R1, taking into account the as built conditions and the pipe modifications. The nuclear research reactor IEA-R1 is a pool type reactor designed by Babcox-Willcox, which is operated by IPEN since 1957. The primary coolant system is responsible for removing the residual heat of the Reactor core. As a part of the life management, a regular inspection detected some degradation in the primary piping system. In consequence, part of the piping system was replaced. The partial renewing of the primary piping system did not imply in major piping layout modifications. However, the stress condition of the piping systems had to be reanalyzed. The structural stress analysis of the primary piping systems is now presented and the final results are discussed. (author)

Energy policies of IEA countries: Denmark 2006 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2006-12-18

Denmark has had a very pro-active energy policy in both energy efficiency and renewable energy while at the same time opening its gas and power markets to competition. The share of renewable energy has increased dramatically, going from 3% of all electricity generation in 1990 to 25% in 2004. At the same time, the government's renewable support policies up to the early 2000s came with a high cost for consumers and taxpayers. However, the current government is very attentive to cost-effectiveness and inclined to market-based approaches. Greater use of cost-benefit analysis, including for offshore wind plants, is crucial in shaping future policies. The review indicates that energy efficiency programmes have historically been more cost-effective than renewable energy programmes in lowering emissions and enhancing energy security. Denmark's energy intensity is 35% below the IEA average, due in substantial part to the government's efforts to improve efficiency. This policy provides an excellent example for other countries, although the review notes that more should be done for transport efficiency.

Upgrading the electrical system of the IEA-R1 reactor to avoid triggering event of accidents

International Nuclear Information System (INIS)

Mello, Jose Roberto de; Madi Filho, Tufic

2015-01-01

The IEA-R1 research reactor at the Institute of Energy and Nuclear Research (IPEN) is a research reactor open pool type, built and designed by the American firm 'Babcox and Wilcox', having as coolant and moderator demineralized light water and Beryllium and graphite, as reflectors. The power supply system is designed to meet the electricity demand required by the loads of the reactor (Security systems and systems not related to security) in different situations the plant can meet, such as during startup, normal operation at power, shutdown, maintenance, exchange of fuel elements and accident situations. Studies have been done on possible accident initiating events and deterministic techniques were applied to assess the consequences of such incidents. Thus, the methods used to identify and select the accident initiating events, the methods of analysis of accidents, including sequence of events, transient analysis and radiological consequences, have been described. Finally, acceptance criteria of radiological doses are described. Only a brief summary of the item concerning loss of electrical power will be presented. The loss of normal electrical power at the IEA-R1 reactor is very common. In the case of Electric External Power Loss, at the IEA-R1 reactor building, there may be different sequences of events, as described below. When the supply of external energy in the IEA-R1 facility fails, the Electrical Distribution Vital System, consisting of 4 (four) generators type 'UPS', starts operation, immediately and it will continue supplying power to the reactor control table, core cooling system and other security systems. To contribute to security, in the electric power failure, starts to operate the Emergency Cooling System (SRE). SRE has the function of removing residual heat from the core to prevent the melting of fuel elements in the event of loss of refrigerant to the core. Adding to the generators with batteries group system, new auxiliary

The history of the IEA. Volume four. Supplement to volumes 1, 2 et 3

2004-01-01

Published in 1994, The History of the International Energy Agency: The First Twenty Years, the comprehensive story of the IEA's decisions since its founding in 1974, has been an invaluable resource to the Agency's Member country governments, to the IEA Secretariat, and to all those who are interested in international, inter-governmental organisations. The author was Richard Scott, a former IEA Legal Counsel. Now, his successor Craig S. Bamberger, has extended The History through most of the Agency's third decade, up to the end of 2003. In this Supplement to Mr. Scott's History, Mr. Bamberger has remained faithful to the structure of the original work, enabling the reader to move easily between time periods when researching a particular subject. Continuity and change are both in evidence. The IEA's basic institutional arrangements remain essentially as Mr. Scott described them in Volume I of The History, but the Supplement's extensive treatment of budget and programme of work issues reflects significant changes in Agency practice, during a period when governments were engrossed in the management and financing of international organisations generally. In the policy realm, the Supplement recounts numerous new initiatives that the IEA has launched, while remaining true to its focus on the 'three E' policy goals: Energy Security, Environmental Protection and Economic Growth

Pottinger, C. (ed.)

2007-05-15

Ensuring energy security and addressing climate change issues in a cost-effective way are the main challenges of energy policies and in the longer term will be solved only through technology cooperation. To encourage collaborative efforts to meet these energy challenges, the IEA created a legal contract - Implementing Agreement - and a system of standard rules and regulations. This allows interested member and non-member governments or other organisations to pool resources and to foster the research, development and deployment of particular technologies. For more than 30 years, this international technology collaboration has been a fundamental building block in facilitating progress of new or improved energy technologies. There are now 41 Implementing Agreements. This is the third in the series of publications highlighting the recent results and achievements of the IEA Implementing Agreements. This document is arranged in the following sections: Cross-cutting activities (sub-sectioned: Climate technology initiative; Energy Technology Data Eexchange; and Energy technology systems analysis programme); End-use technologies (sub-sectioned: Buildings; Electricity; Industry; and Transport; Fossil fuels (sub-sectioned: Clean Coal Centre; Enhanced oil recovery Fluidized bed conversion; Greenhouse Gas R & D; Multiphase flow sciences); Fusion power; Renewable energies and hydrogen; and For more information (including detail on the IEA energy technology network; IEA Secretariat Implementing Agreement support; and IEA framework. Addresses are given for the Implementing Agreements. The publication is based on core input from the Implementing Agreement Executive Committee.

Under the International Energy Agency Wind Implementing Agreement (IEA Wind) Task 11, researchers started examining novel applications for remote sensing and the issues around them during the 51st topical expert meeting about remote sensing in January 2007. The 59th topical expert meeting organized by Task 11 in October 2009 was also dedicated to remote sensing, and the first draft of the Task's recommended practices on remote sensing was published in January 2013. The results of the Task 11 topical expert meetings provided solid groundwork for a new IEA Wind Task 32 on wind lidar technologies. Members of the wind community identified the need to consolidate the knowledge about wind lidar systems to facilitate their use, and to investigate how to exploit the advantages offered by this technology. This was the motivation that led to the start of IEA Wind Task 32 'Lidar Application for Wind Energy Deployment' in November 2011. The kick-off was meeting was held in May 2012.

Materials related to IEA Greenhouse Gas Rand D Program (IEA/GHG) were analyzed. The Sleipner carbon dioxide underground storage workshop is acting to narrow themes for understanding the technologies, observation methods, and research activities. The IEA/GHG has verified the known facts about ocean storage of carbon dioxide, and discussed the important development targets. Researches were made on improving methane recovery efficiency and the possibility of sealing carbon dioxide by injecting carbon dioxide in order to improve recovery of carbon bed methane. The IEA/GHG has developed a methodology for complete fuel cycles of LNG, and evaluated cost and benefit of reducing greenhouse effect gas emission. A process combining electric power generation, carbon dioxide absorption and hot heat energy utilization can reduce emission of carbon dioxide into atmosphere at relatively low cost and low energy loss. The paper also describes reduction of greenhouse effect gas emitted from cement factories, petroleum refining and petro-chemical industries, and offshore petroleum and gas facilities. It also describes influence of forestry on carbon absorption and timber markets. Case studies have discussed effects of modifying power generation plants. (NEDO)

The IEA published 'Energy Technology Perspectives' (ETP) in June 2008. That document reports on IEA scenarios for baseline and low-CO 2 alternative scenarios to 2050, across the energy economy. The study included creating scenarios for transport, using the IEA Mobility Model (MoMo). This paper reports on the transport-related ETP scenarios and describes the model used in the analysis. According to the ETP Baseline scenario, world transport energy use and CO 2 emissions will more than double by 2050. In the most challenging scenario, called 'BLUE', transport emissions are reduced by 70% in 2050 compared to their baseline level in that year (and about 25% below their 2005 levels). There are several versions of the BLUE scenario, but all involve: a 50% or greater improvement in LDV efficiency, 30-50% improvement in efficiency of other modes (e.g. trucks, ships and aircraft), 25% substitution of liquid fossil fuels by biofuels, and considerable penetration of electric and/or fuel-cell vehicles. In the second half of this paper, an overview of the MoMo model is provided. Details on the complete analysis are contained in the ETP 2008 document, available at (www.iea.org). Details of the LDV fuel economy analysis are contained in a separate paper in this collection.

In order to substantially enhance the share of renewable energy technologies in the energy portfolio, it is imperative to accelerate technological advancement and subsequently reduce costs, in combination with novel applications and deployment. This outcome can be significantly supported by a range of RD and D initiatives, if properly designed and implemented. This publication reviews the current status of the renewable energy technologies portfolio and provides guidance on their mid- and long-term development. The study explores the options for the RD&D to achieve breakthroughs that will lead to large-scale markets and identifies what activities should take priority. It also looks at the benefits of increased RD&D funding in terms of technological advancement and cost improvement. It covers renewable energy technologies in the early research stage through to those that have reached a level of maturity. It also lists national renewable energy RD and D trends in IEA member countries.

Since its creation by the International Energy Agency in the late 1970's, the IEA Hydrogen Implementing Agreement (HIA) has been at the forefront of collaborative international hydrogen research and development (R and D) (http://www.ieahia.org. ) The collective body of HIA hydrogen R and D will contribute to definition of the hydrogen economy. The five-year [2004-2009) mission of the IEA HIA is to advance the adoption of a Hydrogen Economy through strategic implementation of collaborative R and D and outreach programs that address key issues and barriers. The three goals for the Second Generation HIA are: Advancement of science and technology via pre-commercial collaborative RD and D programs; Assessment of market environment, including the non-energy sector; and Implementation of outreach program, aimed at community acceptance and support. The HIA launched its Second Generation of hydrogen R and D in the latter part of 2004. The HIA's anniversary report: In Pursuit of the Future: 25 Years of IEA Research towards the realization of Hydrogen Energy Systems (http://ieahia.org/pdfs/IEA_AnniversaryReport_HIA.pdf) chronicles its contributions to hydrogen R and D. As the hydrogen economy takes shape, the HIA is pleased to share highlights of its R and D history together with progress on planned activities and its six current annexes, listed below: Task 15 Photobiological Production of Hydrogen Task 16 Hydrogen from Carbon-Containing Materials Task 17 Solid and Liquid Storage Task 18 Integrated Systems Evaluation Task 19 Safety Task 20 Hydrogen from Waterphotolysis Planned successor annexes in storage and photobiological hydrogen production will also be discussed, along with a task on high temperature hydrogen production that is now in the definition phase. Over 250 experts from the sixteen member HIA countries and the European Union contribute to this portfolio of cutting edge hydrogen R and D and analysis activities. Several other countries are expected to

Focus on Energy Security. Costs, Benefits and Financing of Holding Emergency Oil Stocks

Energy Technology Data Exchange (ETDEWEB)

Stelter, Jan; Nishida, Yuichiro

2013-07-01

Oil is traded in a market where uncertainty, price volatility, and sudden supply disruptions are common characteristics. Natural disasters, political disagreements and wars can seriously disrupt oil supply and demand with consequent detrimental impacts on economic activity. One particularly powerful policy tool that IEA member countries have to respond to such disruptions is the release of emergency oil stocks. In its 40 year history, the IEA released stocks on three occasions to reduce the supply disruptions and the associated economic damage. This paper provides a general guide to the existing emergency stockholding system for those countries who are considering the introduction of new stockholding systems or changes to their existing emergency stocks. It draws together analysis of the costs and benefits of emergency stocks, in addition to exploring options for financing the establishment of stocks.

IEA countries energy policy. Report 1992

International Nuclear Information System (INIS)

1994-01-01

The International Energy Agency is interested by the energy policy of its 23 members countries. This book sums up the evolution of energy policy in 1991 and 1992, sticking particularly to energy proposal and demand, to energy efficiency, to interaction between energy and environment, to the energy technology and to research and development activities. The 23 countries are examined regularly. The elaborate examinations refer to the energy policy of each member country to dictate the common orientation of their policy. Ministers meetings of IEA take place regularly. The latest took place in PARIS on the fourth of June 1993 where the ministers confirmed that there were essential elements of the energy policy and that they recommended to all countries to take that in account in the formulation of their strategies. Beyond the examinations by country, this book contains a whole report which throws into relief the main new acts which were happened in the IEA members countries and a glimpse on the evolution of the energy situation in the no members countries. It gives specific data and informations on the governmental budgets allocated to research and development energy activities. 6 annexes, 12 graphs., 5 tabs

Emergence of Shared Intentionality Is Coupled to the Advance of Cumulative Culture.

Directory of Open Access Journals (Sweden)

Simon D Angus

2015-10-01

Full Text Available There is evidence that the sharing of intentions was an important factor in the evolution of humans' unique cognitive abilities. Here, for the first time, we formally model the coevolution of jointly intentional behavior and cumulative culture, showing that rapid techno-cultural advance goes hand in hand with the emergence of the ability to participate in jointly intentional behavior. Conversely, in the absence of opportunities for significant techno-cultural improvement, the ability to undertake jointly intentional behavior is selected against. Thus, we provide a unified mechanism for the suppression or emergence of shared intentions and collaborative behavior in humans, as well as a potential cause of inter-species diversity in the prevalence of such behavior.

The radiological capacity in the IEA environment, was calculated according to the recommendations of the International Commission on Radiological Protection, in order to assess the management wastes disposal programming. The value of radiological capacity, take into account the isotopic composition, at the production moment, was 850 Ci/year. The IEA radioactive environment disposal, up to now, employed just a small fraction of its capacity. Iodine I-131 air inhalation, and external radiation, derivated from the sediments around the discharged point of Pinheiros river, were the 'critical pathways'; for the second case the 'critical radionuclides' were: Te-125m, Te-123m, Te-127m, I-131 e Cs-137.

The objective of the project is to develop and improve large procurements of solar heating systems in order to be able to place large orders with manufacturers and suppliers. The project work will be carried out as an international co-operation under IEA Task 24 with the title 'Solar Procurement'. By co-ordinating the effort between the 4-6 participating countries, the objective is to purchase at least 10,000 solar heating systems, of this amount 1,000-2,000 in Denmark. Such large orders make it possible for manufacturers and suppliers to deliver systems considerably cheaper, and it will be possible to develop systems for given specifications on output and efficiency. These co-ordinated large orders are expected to improve the price/efficiency conditions by up to 50%. The so called 'procurement process' (co-ordinated international procurement based on goal-oriented system development in co-operation between customers and suppliers/manufacturers) will in the project be followed up by information/marketing, education, financing schemes, service schemes, quality assurance and technical support. The project is divided into two main areas (IEA subtasks). 1: 'Procurement and Marketing' and 2: 'Creation of Tools'. Denmark has been requested to be the project manager of subtask 2, 'Creation of Tools'. (EHS)

Borated stainless steel storage project to the spent fuel of the IEA-R1 reactor

Rodrigues, Antonio Carlos Iglesias; Madi Filho, Tufic; Ricci Filho, Walter

2013-01-01

The IEA-R1 research reactor operates in a regimen of 64h weekly, at the power of 4.5 MW. In these conditions, the racks to the spent fuel elements have less than half of its initial capacity. Thus, maintaining these operating circumstances, the storage will have capacity for approximately six years. Whereas the estimated useful life of the IEA-R1 is around twenty years, it will be necessary to increase the storage capacity for the spent fuel. Dr. Henrik Grahn, expert of the International Atomic Energy Agency on wet storage, visiting the IEA-R1 Reactor (September/2012) made some recommendations: among them, the design and installation of racks made with borated stainless steel and internally coated with an aluminum film, so that corrosion of the fuel elements would not occur. This work objective is the project of high capacity storage for spent fuel elements, using borated stainless steel, to answer the Reactor IEA-R1 demand and the security requirements of the International Atomic Energy Agency.

The Research Reactor IEA-R1 placed at IPEN/CNEN-SP is of the swimming pool type, light water moderated and with graphite reflectors, and was build and designed by Babcock and Wilcox Co. Start up operation was in September the 16{sup th}, 1957, being the first criticality for South Hemisphere. Although designed to operate at 5 MW, the IEA-R1 was operated until 2001 with 2 MW and was suitable for use in basic and applied research as well as the production of medical radioisotopes, industry and natural sciences applications. Due to a recent demand increase on radioisotopes in Brazil for medical diagnoses and therapies applications, IPEN /CNEN updated the IEA-R1 power to 5 MW and to work at continuous operation regime. Studies on the Ageing Management for the Research Reactor IEA-R1 were conducted according to IAEA procedures. As result of these studies critical components within the Ageing Management Program were identified. Also were made recommendations on the implementation of test scheduling and standardization procedures to organize data and documents. One of the main results was the need of monitoring the two heat exchangers, the two primary circuit pumps and the data acquisition system. During monitoring procedures, issues were observed on the IEA-R1 operation at 5 MW mainly due to the ageing of the Babcox and Wilcox TCA heat exchanger, and excessive vibrations at high flow rates on CBC's TCB heat exchanger. So, from 2005 on, it was decided to work with 3,5 MW and provide a new IESA heat exchanger with 5 MW capacity, to substitute the TCA heat exchanger. This work presents results on the commissioning of the new heat exchanger and compares against the values calculated in the IESA project. The results show that the IEA-R1 Reactor can be operated more safety and continuously at 5 MW with the new IESA heat exchanger. (author)

The ratio β/Λ for the IEA-R1 reactor is obtained experimentally through the noise analysis technique. This technique is based on the determination of the power spectral density of the reactor neutron population, with the reactor in a subcritical state driven by a 'white' neutron source. A ratio β/Λ of 43,5 s -1 is estimated from the break frequency of the measured transfer function of the IEA-R1 reactor. (Author) [pt

Energy policies of IEA countries: the Republic of Korea 2006 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-07-01

Through analysis of its existing policies and comparisons with good examples in other IEA countries, this book provides critiques and recommendations for policy improvements. Covering not only traditional energy sectors, but also energy efficiency, renewables and the environment, the IEA report serves as a guide to understanding - and addressing - the energy challenges that face the modern Republic of Korea. The great strides that the Republic of Korea has made over the last three decades are not confined to its economy. Its energy industry has similarly leapt forward in terms of infrastructure and security. Though it has no links to nearby countries that would allow it to rely on electricity imports or piped natural gas, the country has rapidly electrified, built a diverse portfolio of electricity supply, developed a robust nuclear energy industry and become one of the pioneers in the liquefied natural gas trade. As the most recent member of the International Energy Agency (IEA), this progress is remarkable and its enhancement of its policy goals - adding economic efficiency and environmental sustainability to energy security - is commendable. Building on the liberalisation of its economy, the Republic of Korea set out an ambitious plan for reform of its state-controlled natural gas and electricity industries. However, the plans have been stalled and there is currently little vision for effective reform going forward. As the economy makes the transition to one with less phenomenal, more sustainable and less predictable growth, the IEA encourages the Republic of Korea to press forward with liberalisation in order to underpin a more flexible and efficient energy sector. 22 figs., 33 tabs., 3 apps.

Ground source heat is a collective name for tapping, recharging and storing thermal energy at moderate temperature in the bedrock, ground water and soil (renewable energy). By means of heat pumps, ground source heating systems can be used as highly energy efficient and environmentally-friendly heating and cooling in all kinds of buildings. IEA's heat pump programme (IEA HPP) has in the period March 2004 to June 2006 carried out an Annex on heating pump systems based on ground source heat: 'Annex 29 - Ground-source heat pumps overcoming market and technical barriers'. The project has i.a. covered the development of more cost- and energy efficient solutions, identification and analysis of market obstacles, technology transfer and the task of making visible the energy economising potential and environmental gains that this type of systems represent. The six participating countries have been Canada, Japan, Norway, Sweden, USA and Austria (operating agent). Norway's participation in IEA Annex 29 has been financed by ENOVA SF, while SINTEF Energy research AS has been in charge of planning and executing the Norwegian project activities. This report provides a general presentation of ground source heat pump systems, and gives a summary of the most important Norwegian activities in IEA Annex 29, which includes: The development of a Norwegian internet home page (http://www.energy.sintef.no/prosjekt/annex29), preparation of Norwegian status report, initiation, coordination and carrying out of Norwegian research projects and reports, communication of results (technology transfer) in Norway, networking activities towards important market actors in Norway, participation and delivering discourse at international seminars (workshops), and participation at international working sessions (ml)

2010-04-12

Canada, with its diverse and balanced portfolio of energy resources, is one of the largest producers and exporters of energy among IEA member countries. The energy sector plays an increasingly important role for the Canadian economy and for global energy security, as its abundant resource base has the potential to deliver even greater volumes of energy. The federal, provincial and territorial governments of Canada are all strongly committed to the sustainable development of the country's natural resources and have a long-standing and informed awareness of the need for each to contribute to the development of the energy sector. Furthermore, the government of Canada seeks to achieve a balance between the environmentally responsible production and use of energy, the growth and competitiveness of the economy, and secure and competitively priced energy and infrastructure. Nonetheless, the long-term sustainability of the sector remains a challenge. Due to climatic, geographic and other factors, Canada is one of the highest per-capita CO2 emitters in the OECD and has higher energy intensity than any IEA member country. A comprehensive national energy efficiency strategy, coupled with a coordinated climate change policy targeted at the key emitting sectors, is needed. Carbon capture and storage (CCS) is a priority for the federal government and presents Canada with an opportunity to develop a new technology that can reduce greenhouse gas emissions on a large scale. The IEA recommends that Canada provide international leadership in the development of CCS technology. This review analyses the energy challenges facing Canada and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Canada towards a more sustainable energy future.

2011-01-01

The World Energy Outlook 2010 is a comprehensive energy report issued by the IEA. It is rewritten annually to reflect the world's changing energy and economy realities; it also introduces new issues relevant to the energy sector. This year it dealt with Caspian Energy, Energy Poverty and Energy Subsidies. WEO is controversial in few aspects; it still promotes a 450 Scenario which has become out of reach. This year however it introduced a more realistic New Policies Scenario which will need a lot of good will and investments to accomplish. Governmental policies are going to chart future energy sector performance; increasingly this is becoming decided by non-OECD countries. A more pragmatic future energy outlook is needed to reflect developing countries priorities for growth and utilization of local resources and how to accommodate this with abatement priorities through energy efficiency measures and technologies. - Research highlights: → We critically review the findings of the IEA - World Energy Outlook 2010. → The main '450 Scenario' is no longer realistic. → Some of the other indicators like the Energy Development Index are also critically reviewed and improvements proposed.

Non destructive burn up determination of IEA-R1 reactor fuel elements by gamma-ray spectrometry using a Ge(Li) detector

International Nuclear Information System (INIS)

Madi Filho, T.

1982-01-01

A non destructive determination of burn up of low (IEA-14) and high (IEA-80) activity fuel elements used in the IEA-R1 pool reactor was made from the measured distribution of the Cs-137 gamma-ray activity in these elements. For both series of measurements a 73,7 c.c. Ge(Li) detector was used in 'well collimated' geometry. Where as IEA-14, removed from the reactor some 20 years, showed a gamma-ray spectrum essentially due to Cs-137, IEA-80, with a cooling time of 5 years, showed a more complex spectrum due to the greater number of fission products remaining. The S.I out-of-pool assembly was calibrated using Cs-137 and Co-60 point and Ag-110m plane sources. These measurements provided the necessary constants used to calculate fuel burn-up from measured relative activity distributions of fuel elements. Detailed fuel plate transmission measurements made with the Cs-137 source showed the plates to be highly homogeneous. High activity fuel elements were measured in the S.II in-pool assembly in which the detector was locate on the moveable pool bridge and the test element was positioned immediately below the detector 2.17m below the pool surface. Measurements made in the S.II assembly were normalised with respect to the measured activity of the IEA-14 element. The measured burn up of the IEA-14 and IEA-80 elements obtained in this work is 3.22.10 - 3 gms and 24.44gms. These values may be compared with respective values of 2.63.10 - 3 gms and 61.11gms given by 'total reactor energy/flux distribution' calculations. Calculated errors for the U-235 burn up are 7.4% (IEA-14) and 10.1% (IEA-80). A detailed evaluation of the errors associated with both sets of measurements is given. (Author) [pt

Energy use in the new millenium. Trends in IEA countries

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-09-10

At their Gleneagles Summit in July 2005, G8 leaders identified climate change and securing clean energy and sustainable development as key global challenges. They agreed that we must transform the way we use energy and that we must start now. Improved energy efficiency is essential to meeting this goal. Therefore, the G8 asked the IEA to provide analysis of energy use and efficiency developments in buildings, appliances, transport and industry. This publication is a response to the G8 request. Looking back, it shows how changes in energy efficiency, economic structure, income, prices and fuel mix have affected recent trends in energy use and CO2 emissions in IEA countries. The results are a 'wake-up call' for us all. Since 1990, the rate of energy efficiency improvement in IEA countries has been less than 1% per year - much lower than in previous decades and not nearly enough to stem the growth of CO2 emissions. If we are to tackle climate change and move towards a sustainable energy future then this rate will need to double. We must - and we can - do better. By means of in-depth energy indicators, this publication provides important insights to policy-makers about current energy use and CO2 emission patterns that will help shape priorities for future action.

Oil and Gas Emergency Policy: Sweden 2012 update

Energy Technology Data Exchange (ETDEWEB)

NONE

2012-07-01

Oil and natural gas represented respectively 27% and 3% of Sweden’s total primary energy supply (TPES) in 2010. With coal representing 5% of TPES, Sweden has the lowest share of fossil fuels in the energy supply mix among IEA member countries. This is a significant difference from the mid-1970s, when fossil fuels made up three-quarters of Sweden’s energy supply, and is the result of a concerted effort to move away from the use of oil through the development of nuclear and renewable energy sources. Sweden’s energy policy seeks to further increase the share of renewable energy sources, including having them provide half of all energy, and 10% of all transport needs, by 2020. The share of fossil fuel is also to be further reduced, through plans to fully eliminate their use for heating purposes by 2020 and having a vehicle stock in Sweden that is ''independent'' of fossil fuels by 2030. Under this policy, demand for both oil and natural gas is anticipated to decline from current levels. Oil demand in Sweden was nearly 330 thousand barrels per day (kb/d) in 2011. While fully dependent on imports to meet domestic oil demand, Sweden is a net exporter of refined oil products. Overall oil demand will likely decline in the coming decade, however demand for oil in the transport sector is expected to grow. At the same time, oil demand will be ever more concentrated on transport diesel, with demand for the fuel reaching over 110 kb/d by 2020 compared to just under 80 kb/d in 2011. Concerning natural gas, consumption in Sweden totalled 1.3 billion cubic metres (bcm) in 2011, all of which was supplied via a single interconnector with Denmark. While natural gas plays only a minor role in Sweden’s TPES, its role in the energy supply of southern and western Sweden is much more substantial, accounting for around 20% of the area’s total energy use. Around 30 large consumers, including CHP plants, account for roughly 80% of total gas demand in the country

This report aims to provide a document that gives guidance on the issue of biomass energy policies in OECD countries. The main conclusions and messages from this project were published in a joint IEA RETD and IEA Bioenergy Position Paper and presented at the COP15 in December 2009. As the main contributor to renewable energy around the world (about 10% of total energy consumption), the term 'biomass for energy' covers a broad range of products, including traditional use of wood for cooking and heating, industrial process heat, co-firing of biomass in coal-based power plants, biogas and biofuels. In many OECD countries, bioenergy is deployed to reduce fossil fuel use and improve security of supply, reduce greenhouse gas emissions and/or create new employment. Modern biomass can be more expensive than its fossil competitors, however, and there is evidence that biomass, unless produced sustainable, could have significant negative environmental and socio-economic impacts. This report elaborates on how to improve the use of biomass for energy.

2006-01-01

Emerging technologies are now initiating new industries and transforming old ones with tremendous power. They are different games compared with established technologies with distinctive characteristics of knowledge management in knowledge-based and technological-innovation-based competition. How to obtain knowledge advantage and enhance competences by knowledge sharing for emerging-technology-based strategic alliances (ETBSA) is what we concern in this paper. On the basis of our previous work on emerging technologies'distinctive attributes, we counter the wide spread presumption that the primary purpose of strategic alliances is knowledge acquiring by means of learning. We offers new insight into the knowledge sharing approaches of ETBSAs - the knowledge integrating approach by which each member firm integrates its partner's complementary knowledge base into the products and services and maintains its own knowledge specialization at the same time. So that ETBSAs should plan and practice their knowledge sharing strategies from the angle of knowledge integrating rather than knowledge acquiring. A four-dimensional framework is developed to analyze the advantages and disadvantages of these two knowledge sharing approaches. Some cases in electronic industry are introduced to illustrate our point of view.

The objective of the project is to develop and improve large procurements of solar heating systems in order to be able to place large orders with manufacturers and suppliers. The project work will be carried out as an international co-operation under IEA Task 24 with the title 'Solar Procurement'. By co-ordinating the effort between the 4-6 participating countries, the objective is to purchase at least 10,000 solar heating systems, of this amount 1,000-2,000 in Denmark. Such large orders make it possible for manufacturers and suppliers to deliver systems considerably cheaper, and it will be possible to develop systems for given specifications on output and efficiency. These co-ordinated large orders are expected to improve the price/efficiency conditions by up to 50%. The so called 'procurement process' (co-ordinated international procurement based on goal-oriented system development in co-operation between customers and suppliers/manufacturers) will in the project be followed up by information/marketing, education, financing schemes, service schemes, quality assurance and technical support. The project is divided into two main areas (IEA subtasks). 1: 'Procurement and Marketing' and 2: 'Creation of Tools'. Denmark has been requested to be the project manager of subtask 2, 'Creation of Tools'. (EHS)

Energy policies of IEA countries: Sweden - 2008 review

Sweden is one of the leading IEA countries in the use of renewable energy and has a long tradition of ambitious and successful policies to improve energy efficiency. Compared to the other IEA countries, Sweden's CO2 emissions per capita and per unit of GDP are low, partly owing to efficient and low-carbon space heating, and virtually carbon-free electricity generation. The country also remains a forerunner in electricity market liberalisation. Still, even if Sweden has continued to make progress in most areas of its energy policy since the IEA last conducted an in-depth review in 2004, there is room for improvement. As Sweden plans to further increase the use of renewable energy, it is crucial that these supplies are produced and used in the most sustainable manner for the environment and the economy as a whole. With regard to CO2 emissions, more can be done in all sectors, but as transport is the largest polluter and its emissions are increasing, it is the logical focus for Sweden's efforts to reduce emissions further. This is a significant challenge. Nuclear provides almost half of the electricity in Sweden, at a low cost and without CO2 emissions. But the future of nuclear power in the national power mix is still uncertain. To provide clear guidance to the electricity sector, Sweden will need to resolve the ambiguity about the future of nuclear power in the country. This review analyses the energy challenges facing Sweden and provides critiques and recommendations for further policy improvements. It is intended to provide input to Swedish energy policy makers to help them identify a path towards a more sustainable energy future.

The IEA report takes an in-depth look at the energy challenges facing Germany, and through comparisons with good examples in other IEA countries, provides critiques and recommendations for policy improvements. The review guides the country towards a sustainable energy future. Few countries can have as great an impact on energy policy in Europe as Germany. Its large size and strategic location make it a critical component of the region's energy markets - as a result, sound energy policies and strong energy market design are a necessity. In these respects, Germany continues to make notable progress. The country has continued to reform its electricity and natural gas markets, set a timetable to phase out coal subsidies, is meeting key climate and environmental targets and is bringing energy, efficiency and environment to the top of the world agenda with its presidencies of both the G8 and European Union. The International Energy Agency (IEA) praises these efforts. Nevertheless, work remains to be done to further improve German energy policies and markets. The planned phase-out of nuclear power over the coming years would have major impacts on the country's energy mix, raising concerns about energy security, economic efficiency and environmental sustainability for the country and for Europe as a whole. Furthermore, though progress has been made, more needs to be done to set a truly level playing field for competition to develop in gas and electricity markets, which means effective unbundling of transport activities and a strongly empowered regulatory authority. Finally, the country's environmental policies, though helping meet ambitious goals, are expensive - and sometimes various policies work at cross-purposes. 22 figs., 27 tabs., 4 apps.

Implementing Agreements (IAs) are used widely in international collaborative work within the International Energy Agency (IEA). These agreements are meant to be very flexible depending on the nature of the work and the interests of the participating countries. Many IAs are directed at the development of specific technologies, while a number of IAs are primarily used to facilitate information collection and dissemination. There are also a number of agreements that do not deal directly with technology development, but deal with environmental, economic and safety aspects of the technologies under development. The IEA Bioenergy Agreement is a prime example of how Implementing Agreements can be utilised to establish and expand cooperative research for the effective leveraging of technical knowledge and financial resources in finding solutions to the future needs of a growing energy dependent world. As will be illustrated, these activities are important to the commercialisation and deployment of bioenergy technologies, which increasingly are being visualized as one of the few options that can maintain and promote economic and environmental stability

The knowledge of the neutron flux distribution in research reactors is important because it gives the power distribution over the core, and it provides better conditions to perform experiments and sample irradiations. The measured neutron flux distribution can also be of interest as a means of comparison for the calculational methods of reactor analysis currently in use at this institute. The thermal neutron flux distribution of the IEA-R1 reactor has been measured with the miniature chamber WL-23292. For carrying out the measurements, it was buit a guide system that permit the insertion of the mini-chamber i between the fuel of the fuel elements. It can be introduced in two diferent positions a fuel element and in each it spans 26 axial positions. With this guide system the thermal neutron flux distribution of the IEA-R1 nuclear reactor can be obtained in a fast and efficient manner. The element measured flux distribution shows clearly the effects of control rods and reflectors in the IEA-R1 reactor. The difficulties encountered during the measurements are mentioned with detail as well as the procedures adopteed to overcome them. (Author) [pt

2006-09-23

New Zealand faces some serious energy sector challenges, requiring special attention to security of supply issues, both in oil and gas domains. Natural gas production from the major Maui field is rapidly declining. New Zealand's greenhouse gas emissions are rising: the most recent estimates put them at 21% above their Kyoto target over the first commitment period. These challenges are not insurmountable. New Zealand's energy policy is characterised by a commitment to free and open markets complimented by light-handed regulation. The IEA commends this approach and encourages continued policy improvements and enhancements. The energy policy review of New Zealand offers a comprehensive analysis of the country's energy sector, evaluating its strengths and weaknesses across the fuel mix, as well as looking at broader issues such as energy efficiency, environmental performance and technology research and development. It also includes policy critiques and recommendations, drawing on experience across IEA member countries. 33 figs., 21 tabs., 3 annexes.

The IEA-R1 research reactor operates in a regimen of 64h weekly, at the power of 4.5 MW. In these conditions, the racks of the spent fuel elements have less than half of its initial capacity. Thus, maintaining these operating conditions, the storage will have capacity for about six years. Since the estimated useful life of the IEA-R1 is about another 20 years, it will be necessary to increase the storage capacity of spent fuel. Dr. Henrik Grahn, expert of the International Atomic Energy Agency on wet storage, visiting the IEA-R1 Reactor (September/2012) made some recommendations: among them, the design and installation of racks made with borated stainless steel and internally coated with an aluminum film, so that corrosion of the fuel elements would not occur. After an extensive literature review of material options given for this type of application we got to Boral® manufactured by 3M due to numerous advantages. This paper presents studies on the analysis of criticality using the computer code MCNP 5, demonstrating the possibility of doubling the storage capacity of current racks to attend the demand of the IEA-R1 reactor while attending the safety requirements the International Atomic Energy Agency.

Since its inauguration in 1957, the IEA-R1 research reactor has been used mainly for research, development and teaching by scientific community. In the last years, with the increase of the commercial radiopharmaceutical production by Radiopharmacy Center of IPEN, the IEA-R1 reactor was recognized as a service supplier for that center and has received a treatment more commercial from IPEN Management. In 1999 the radiopharmaceutical production obtained the NBR ISO 9002 Certification, since that the IPEN Management considered convenient to invest in the certification of its internal suppliers. In this context, in 2001 the Research Reactor Center (CRPq) began the implantation of a Quality Management System (QMS) based on NBR 9001: 2000 standard, for activities related to the operation and maintenance of the IEA-R1 research reactor and irradiation services. This QMS was structured to incorporate tools already implemented in order to complain the requirements related to nuclear and radiological safe for a nuclear installation established by the regulatory organism. The QMS is supported by a documentation system composed of approximately 150 documents including quality manual, business and action plans, operational procedures and work instruction. Carlos Alberto Vanzolini Foundation (FCAV), an INMETRO certified organism, certified the 'Operation and Maintenance of the IEA-R1 Research Reactor and Irradiation Services' in December 2002. In 2003 and 2004, the QMS was audited by FCAV that determined the maintenance of the certification. This work presents the main steps of the QMS implementation, including the difficulties found and results obtained in the process. (author)

Shared Decision-making in the Emergency Department: Respecting Patient Autonomy When Seconds Count.

Shared decision-making (SDM), a collaborative process in which patients and providers make health care decisions together, taking into account the best scientific evidence available, as well as the patient's values and preferences, is being increasingly advocated as the optimal approach to decision-making for many health care decisions. The rapidly paced and often chaotic environment of the emergency department (ED), however, is a unique clinical setting that offers many practical and contextual challenges. Despite these challenges, in a recent survey emergency physicians reported there to be more than one reasonable management option for over 50% of their patients and that they take an SDM approach in 58% of such patients. SDM has also been selected as the topic on which to develop a future research agenda at the 2016 Academic Emergency Medicine consensus conference, "Shared Decision-making in the Emergency Department: Development of a Policy-relevant Patient-centered Research Agenda" (http://www.saem.org/annual-meeting/education/2016-aem-consensus-conference). In this paper the authors describe the conceptual model of SDM as originally conceived by Charles and Gafni and highlight aspects of the model relevant to the practice of emergency medicine. In addition, through the use of vignettes from the authors' clinical practices, the applicability of SDM to contemporary EM practice is illustrated and the ethical and pragmatic implications of taking an SDM approach are explored. It is hoped that this document will be read in advance of the 2016 Academic Emergency Medicine consensus conference, to facilitate group discussions at the conference. © 2015 by the Society for Academic Emergency Medicine.

The arena of information exchange and discussions was prepared through use of the Internet homepage for the IEA/DSM implementation agreement. Necessary official policies were also made available. Points of precautions when the mechanisms of other countries are used in Japan: the key to the success depends on social or cultural situations that work as the base; therefore, comparisons and analyses are necessary on such elements as customers as the object, energy projects and governments; compatibility of the situation and pattern of the demand side with the DSM technologies governs the reasonability thereof; the types of the mechanisms are narrowed down by size of the customer division, consumption pattern, electric power quality and safety, and needs on the flexibility; proliferation levels of the DSM technologies determine the appropriate mechanisms; and how the DSM is conceived against the final consumption is governed by the conception by both of the customers and the government.

2003-01-01

This volume contains an analysis of developments in energy policies in the Member countries of the International Energy Agency. It features an overview of major trends in the energy markets, notably the renewed interest in energy security on the part of policy-makers. The study describes how, during the period before and during the war in Iraq, the IEA successfully worked to secure oil supply. 2003 was also a year when growing gas demand and rising import dependency in most IEA Member countries obliged energy policy makers to look at the longer term issue of security of gas supply. In addition to these external developments, an internal dimension of energy security arose in the context of electricity and gas market reform. The book also describes the efforts by countries having ratified the Kyoto Protocol to implement the agreements and the trend of energy R and D policies, as well as developments in energy security and energy market reform in major non-OECD countries. It includes: summaries of the in-depth reviews of Austria, Hungary, Italy, Ireland, Japan and Switzerland conducted from October 2002 to June 2003. The full reviews are published separately

A critical review of IEA's oil demand forecast for China

International Nuclear Information System (INIS)

Nel, Willem P.; Cooper, Christopher J.

2008-01-01

China has a rapidly growing economy with a rapidly increasing demand for oil. The International Energy Agency (IEA) investigated possible future oil demand scenarios for China in the 2006 World Energy Outlook. The debate on whether oil supplies will be constrained in the near future, because of limited new discoveries, raises the concern that the oil industry may not be able to produce sufficient oil to meet this demand. This paper examines the historical relationship between economic growth and oil consumption in a number of countries. Logistic curve characteristics are observed in the relationship between per capita economic activity and oil consumption. This research has determined that the minimum statistical (lower-bound) annual oil consumption for developed countries is 11 barrels per capita. Despite the increase reported in total energy efficiency, no developed country has been able to reduce oil consumption below this lower limit. Indeed, the IEA projections to 2030 for the OECD countries show no reduction in oil demand on a per capita basis. If this lower limit is applied to China, it is clear that the IEA projections for China are under-estimating the growth in demand for oil. This research has determined that this under-estimation could be as high as 10 million barrels per day by 2025. If proponents of Peak Oil such as Laherrere, Campbell and Deffeyes are correct about the predicted peak in oil production before 2020 then the implications of this reassessment of China's oil demand will have profound implications for mankind

Mello, Jose Roberto de; Madi Filho, Tufic

The IEA-R1 reactor of the Nuclear and Energy Research Institute (IPEN-CNEN/SP), is a research reactor open pool type, designed and built by the U.S. firm Babcock and Wilcox, having, as coolant and moderator, deionized light water and beryllium and graphite, as reflectors. Until about 1988, the reactor safety systems received power from only one source of energy. As an example, it may be cited the control desk that was powered only by the vital electrical system 220V, which, in case the electricity fails, is powered by the generator group: no-break 220V. In the years 1989 and 1990, a reform of the electrical system upgrading to increase the reactor power and, also, to meet the technical standards of the ABNT (Associacao Brasileira de Normas Tecnicas) was carried out. This work has the objective of showing the relationship between the electric power system and the IEA-R1 reactor security. Also, it demonstrates that, should some electrical power interruption occur, during the reactor operation, this occurrence would not start an accident event. (author)

Seebregts, A.J. [Energy research Centre of the Netherlands (Netherlands)], E-mail: seebregts@ecn.nl

2010-04-15

This technology brief on gas-fired power is part of a series produced by the IEA called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of combined-cycle gas turbines (CCGT). CCGT's have become the technology of choice for new gas-fired power plants since the 1990's.

The main neutron parameters of the research reactor IEA-R1 were calculated using computer programs to generate cross sections and criticality calculations. A calculation procedure based on the programs available in the Processing Center Data of IEA was established and centered in the HAMMER and CITATION system. A study was done in order to verify the validity and accuracy of the calculation method comparing the results with experimental data. Some operating parameters of the reactor, namely the distribution of neutron flux, the critical mass, the variation of the reactivity with the burning of fuel, and the dead time of the reactor were determined

We keep on truckin': Trends in freight energy use and carbon emissions in 11 IEA countries

2012-01-01

Based on detailed national and international data on freight transportation, we analyze trends in freight CO 2 emissions in 11 IEA countries from the earliest year of data availability to 2007–2010. The cross-country comparison of the freight transportation sector indicates that per capita CO 2 emissions span a wide range and are mostly determined by local needs without full knowledge or coordination with policies and practices in other countries. Over the last several decades, while many developed countries have experienced decreased coupling between total freight activity (measured in tonne-km) and income, no major indication of decreased coupling between trucking and income was found. Rather, the coupling has been strengthened in many countries due to a continued increase in the share of trucking in total freight activity. The energy intensity of trucking has exhibited very large variation among the countries, and its recent international trends are mixed, providing greater challenges to reduce freight CO 2 emissions. Modal shift toward rail away from truck presents a sizeable opportunity to reduce freight CO 2 emissions, although the potential gain varies widely among the countries. - Highlights: ► We analyze trends in freight CO 2 emissions in 11 IEA countries. ► Many of them experienced decreased coupling between freight and income. ► No major indication of decoupling was found between trucking and income. ► The energy intensity of trucking exhibited very large variation. ► The trends of trucking energy intensity are mixed. ► There is a huge opportunity of reducing emissions by shifting toward rail.

2008-09-04

For the first time, the IEA has reviewed the energy policies of the European Union which shape the energy use of almost 500 million citizens in 27 EU member countries. A unique entity governed under complex and almost constantly evolving structures, the EU constitutes a challenge for energy policy makers. Its energy policy has a global impact, not only because of its 16% share of world energy demand, but also because of the EU leadership in addressing climate change. Strong policy drives are underway in the EU to achieve the completion of the internal energy market, increase renewable energy supply, reduce CO2 emissions and make the EU more energy-efficient. Concerns about security of supply have also led to a greater focus on improved energy relations with supplier countries, and new institutional structures are being put in place. How much progress has been made in the field of security, internal market and external energy policies? And in which of these areas has the EU already implemented a fully integrated policy? This publication addresses these questions and also analyses the impact of the most recent major EU policy measures, in particular the Energy and Climate Package of January 2008 and the 3rd Liberalisation Package of September 2007. This book finds that both of these proposals are highly ambitious. But implementing them and reviewing both volume and allocation of energy R and D will be necessary to achieve a sustainable energy future in a fully competitive integrated EU energy market.

2017-08-01

In 2012 the International Energy Agency (IEA) Heat Pump Programme (now the Heat Pump Technologies (HPT) program) established Annex 41 to investigate technology solutions to improve performance of heat pumps for cold climates. Four IEA HPT member countries are participating in the Annex – Austria, Canada, Japan, and the United States (U.S.). The principal focus of Annex 41 is on electrically driven air-source heat pumps (ASHP) since that system type has the lowest installation cost of all heat pump alternatives. They also have the most significant performance challenges given their inherent efficiency and capacity issues at cold outdoor temperatures. Availability of ASHPs with improved low ambient performance would help bring about a much stronger heat pump market presence in cold areas, which today rely predominantly on fossil fuel furnace heating systems.

Storm in the electricity sector: the emergence of a sharing economy in the case of Netherlands

International Nuclear Information System (INIS)

Vernay, Anne-Lorene; Gauthier, Caroline

2017-01-01

Dominated by a few actors, the electricity sector has long been very stable. Today, it is facing significant disruption as a result of two political decisions: the liberalization of the sector and the signing of the Kyoto protocol. Surprisingly, the sector is also experiencing the emergence of a new paradigm: that of the sharing economy. The sharing economy is historically unknown in the sector where its appearance seemed rather unlikely. This article traces the emergence and ascension of this paradigm in the Netherlands from the 1980's to nowadays. A business model perspective is adopted. The business model describes how firms create, deliver and capture value. This article shows that the transformation is not a technical one but rather a managerial one with the development of new ways of organizing the production of electricity. It also shows that the sector went from a situation where a small number of isolated initiatives were present to one where an ecosystem was created around sharing activities with many actors present. These actors sometimes compete with each other but, more often, they are complementary to one another. The article goes on to discuss the various forms that the sharing economy takes in the electricity sector and the ways that firms, through their business models, facilitated the emergence and development of this paradigm. Finally, this article criticizes the use of the business model as an instrument to analyse the evolution of a sector

Estonia 2013: Energy Policies Beyond IEA Countries

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-08-01

One of the fastest-growing economies in the OECD, Estonia is actively seeking to reduce the intensity of its energy system. Many of these efforts are focused on oil shale, which the country has been using for almost a century and which meets 70% of its energy demand. While it provides a large degree of energy security, oil shale is highly carbon-intensive. The government is seeking to lessen the negative environmental impact by phasing out old power plants and developing new technologies to reduce significantly CO2 emissions. The efforts on oil shale complement Estonia’s solid track record of modernising its overall energy system. Since restoring its independence in 1991, Estonia has fully liberalised its electricity and gas markets and attained most national energy policy targets and commitments for 2020. It has also started preparing its energy strategy to 2030, with an outlook to 2050. Estonia is also promoting energy market integration with neighbouring EU member states. The strengthening of the Baltic electricity market and its timely integration with the Nordic market, as well as the establishment of a regional gas market, are therefore key priorities for Estonia. Following its accession to the Organisation for Economic Co-operation and Development (OECD) in 2010, Estonia applied for International Energy Agency (IEA) membership in 2011. This review of Estonia’s energy policies is part of the IEA accession process. It analyses the energy policy challenges and opportunities facing Estonia, and provides critiques and recommendations for future policy improvements. It is intended to guide the country towards a more secure and sustainable energy future.

This study aims to present a broad view of energy RTD expenditures of Belgium, Luxembourg, and the Netherlands, in the public domain and by private enterprises. Data is provided as much as possible by disaggregating into a format of the IEA (IEA code). IEA data serve as the starting point for data collection. The main task is to fill in the gaps in the database, viz.: Completing the IEA database for Belgium with regard to public energy RTD; Starting with a database of public energy RTD for Luxembourg; Collecting, retrieving, and analysing private energy RTD data for the Netherlands. The latter data, based on a 'bottom-up' approach, are compared to recent data of SenterNovem based on an R and D subsidy scheme in the Netherlands. The private energy RTD expenditures from both sources (the bottom-up approach in this study and the data of SenterNovem) are combined to one database of private energy RTD that may be used for, e.g., the IEA

The IEA workshop on Daylight in Buildings was held in Copenhagen on March 14-16, 1994. At the workshop, presentations were given on key topics as a basis for discussions by the experts participating in the meeting. The presentations and discussions covered a range of technical, architectural and amenity aspects of daylighting in buildings. A great interest in research collaboration on daylight was expressed, and it was agreed that plenty of work still needs to be done, and that the appropriate form of work would be an IEA Task. It was agreed that daylighting systems and control strategies should be evaluated and tested in test rooms, as well as in existing buildings as case studies. Furthermore, the workshop expressed that one of the best ways to realize and present the Task results to practice would be through a few demonstration buildings, build in different countries and under different climatic conditions.

IEA HPP Annex 29 - ground-source heat pumps overcoming technical and market barriers. Status report Norway

International Nuclear Information System (INIS)

Stene, Joern

2004-12-01

Norway is a member of Annex 29, 'Ground-Source Heat Pump Systems Overcoming Technical and Market Barriers' (2004-2006), organized under the umbrella of the International Energy Agency (IEA) and the IEA Heat Pump Programme (HPP). The 7 participating countries are Austria (Operating Agent), Canada, Japan, Norway, Spain, Sweden and the USA. The Norwegian participation is financed by ENOVA SF, and SINTEF Energy Research is responsible for planning and carrying out the Norwegian activities. This report provides a status for ground-source heat pump (GSHP) systems in Norway with regard to state-of-the-art technology, installation examples, geological data, costs and market opportunities. A Norwegian Internet home page for ground-source heat pump systems (www.energy.sintef.no/prosjekt/Annex29) is also presented. GSHP systems in Norway are classified as direct systems (groundwater and soil/ground) and indirect closed-loop systems (vertical-rock and horizontal-soil/ground). The vast majority of the installations are indirect closed-loop systems utilizing vertical boreholes in rock as a heat source, heat sink and thermal energy storage. GSHP systems are relatively capital intensive installations, but they achieve high energy efficiency due to the relatively high and stable heat source temperature and the fact that a considerable share of the cooling demand in non-residential buildings can be covered by means of free cooling. In order to obtain energy efficient and reliable GSHP installations, it is important to implement a total quality concept where focus is on quality and system integration during all stages of the project. A life cycle analysis (LCA) will be an important tool in such a concept, since both the investment costs as well as the lifetime operational and maintenance costs are included (author) (ml) Litt usikker pae tag 620- ikke en vanlig sintef rapportkode

Conventional Oil and Gas Technologies. IEA ETSAP technology brief P01

Energy Technology Data Exchange (ETDEWEB)

Seljom, Pernille [IFE (Norway)], E-mail: pernille.seljom@ife.no

2010-05-15

This technology brief on conventional oil and gas technologies is part of a series produced by the IEA ETSAP agreement called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of oil and gas exploration, development, and production/recovery technologies.

Shared Living and Sustainability: Emerging Trends in the Tourism Industry

Directory of Open Access Journals (Sweden)

Paul Valva

2014-12-01

Full Text Available An emerging concept in accommodations in the travel industry called Shared Living is blurring the lines between hospitality and residential living and is moving the industry towards greater ecological and social sustainability. Changing trends brought about by the sustainability challenge, climate change, technological advancements and increasing affluence and cultural awareness are disrupting the tourism industry. Meeting clients’ needs for Leisure and Relaxation is not enough. Increasingly sustainability-conscious travelers expect their fundamental needs of Participation, Creation and Identity to be fulfilled as well. Today’s travelers want to do more than eat, sleep and sightsee – they want to interact with the local communities they are visiting. But traditional accommodations offer little opportunity for travelers to engage with fellow travelers or local communities. Emerging trends in accommodations are increasingly connecting travelers to the people, organizations and projects that are changing lives and transforming communities. By understanding and adapting to the trends, the tourism industry can both contribute towards ecological social sustainability and reap the business benefits presented by the sustainability challenge of our time.

IEA-R1 primary and secondary coolant piping systems coupled stress analysis

International Nuclear Information System (INIS)

Fainer, Gerson; Faloppa, Altair A.; Oliveira, Carlos A.; Mattar Neto, Miguel

2013-01-01

The aim of this work is to perform the stress analysis of a coupled primary and secondary piping system of the IEA-R1 based on tridimensional model, taking into account the as built conditions. The nuclear research reactor IEA-R1 is a pool type reactor projected by Babcox-Willcox, which is operated by IPEN since 1957. The operation to 5 MW power limit was only possible after the conduction of life management and modernization programs in the last two decades. In these programs the components of the coolant systems, which are responsible for the water circulation into the reactor core to remove the heat generated inside it, were almost totally refurbished. The changes in the primary and secondary systems, mainly the replacement of pump and heat-exchanger, implied in piping layout modifications, and, therefore, the stress condition of the piping systems had to be reanalyzed. In this paper the structural stress assessment of the coupled primary and secondary piping systems is presented and the final results are discussed. (author)

IEA Annex 26: Advanced Supermarket Refrigeration/Heat Recovery Systems

Energy Technology Data Exchange (ETDEWEB)

Baxter, VAN

2003-05-19

With increased concern about the impact of refrigerant leakage on global warming, a number of new supermarket refrigeration system configurations requiring significantly less refrigerant charge are being considered. In order to help promote the development of advanced systems and expand the knowledge base for energy-efficient supermarket technology, the International Energy Agency (IEA) established IEA Annex 26 (Advanced Supermarket Refrigeration/Heat Recovery Systems) under the ''IEA Implementing Agreement on Heat Pumping Technologies''. Annex 26 focuses on demonstrating and documenting the energy saving and environmental benefits of advanced systems design for food refrigeration and space heating and cooling for supermarkets. Advanced in this context means systems that use less energy, require less refrigerant and produce lower refrigerant emissions. Stated another way, the goal is to identify supermarket refrigeration and HVAC technology options that reduce the total equivalent warming impact (TEWI) of supermarkets by reducing both system energy use (increasing efficiency) and reducing total refrigerant charge. The Annex has five participating countries: Canada, Denmark, Sweden, the United Kingdom, and the United States. The working program of the Annex has involved analytical and experimental investigation of several candidate system design approaches to determine their potential to reduce refrigerant usage and energy consumption. Advanced refrigeration system types investigated include the following: distributed compressor systems--small parallel compressor racks are located in close proximity to the food display cases they serve thus significantly shortening the connecting refrigerant line lengths; secondary loop systems--one or more central chillers are used to refrigerate a secondary coolant (e.g. brine, ice slurry, or CO2) that is pumped to the food display cases on the sales floor; self-contained display cases--each food display case

Characterization of the water filters cartridges from the iea-r1 reactor using the Monte Carlo method

International Nuclear Information System (INIS)

Costa, Priscila; Potiens Junior, Ademar J.

2015-01-01

Filter cartridges are part of the primary water treatment system of the IEA-R1 Research Reactor and, when saturated, they are replaced and become radioactive waste. The IEA-R1 is located at the Nuclear and Energy Research Institute (IPEN), in Sao Paulo, Brazil. The primary characterization is the main step of the radioactive waste management in which the physical, chemical and radiological properties are determined. It is a very important step because the information obtained in this moment enables the choice of the appropriate management process and the definition of final disposal options. In this paper, it is presented a non-destructive method for primary characterization, using the Monte Carlo method associated with the gamma spectrometry. Gamma spectrometry allows the identification of radionuclides and their activity values. The detection efficiency is an important parameter, which is related to the photon energy, detector geometry and the matrix of the sample to be analyzed. Due to the difficult to obtain a standard source with the same geometry of the filter cartridge, another technique is necessary to calibrate the detector. The technique described in this paper uses the Monte Carlo method for primary characterization of the IEA-R1 filter cartridges. (author)

Conditions for the Emergence of Shared Norms in Populations with Incompatible Preferences

Science.gov (United States)

Helbing, Dirk; Yu, Wenjian; Opp, Karl-Dieter; Rauhut, Heiko

2014-01-01

Understanding norms is a key challenge in sociology. Nevertheless, there is a lack of dynamical models explaining how one of several possible behaviors is established as a norm and under what conditions. Analysing an agent-based model, we identify interesting parameter dependencies that imply when two behaviors will coexist or when a shared norm will emerge in a heterogeneous society, where different populations have incompatible preferences. Our model highlights the importance of randomness, spatial interactions, non-linear dynamics, and self-organization. It can also explain the emergence of unpopular norms that do not maximize the collective benefit. Furthermore, we compare behavior-based with preference-based punishment and find interesting results concerning hypocritical punishment. Strikingly, pressuring others to perform the same public behavior as oneself is more effective in promoting norms than pressuring others to meet one’s own private preference. Finally, we show that adaptive group pressure exerted by randomly occuring, local majorities may create norms under conditions where different behaviors would normally coexist. PMID:25166137

Olga Novikova

2017-08-01

Full Text Available The sharing economy is an emerging phenomenon that shapes the cultural, economic, and social landscape of our modern world. With variations of the concept of the sharing economy emerging in so many fields, the area of shared mobility – the shared use of a motor vehicle, bicycle, or other mode that enables travellers to gain short-term access to transportation modes on an on-demand basis – has developed as the forerunner of the transformation to be expected in other areas. This article examines how the sphere of personal mobility has been affected by the growth of sharing economy. It contributes to the growing body of shared mobility literature by uncovering innovative mobility-based models that represent solutions on the intersection of shared mobility, physical infrastructure, and integrated-mobility schemes.

Under the International Energy Agency Solar Heating and Cooling Programme, Task 24 Solar Procurement 5 countries co-operate (the Netherlands, Sweden, Canada, Switzerland and Denmark) on increased sale of solar heating plants i.a. by identifying buyer groups, joint calls for tenders and specification of requirements. The work is divided into 2 subtasks. Subtask A concerns the work connected with identifying buyer groups and starting sales and subtask B concerns the delivery of the necessary background material. Subtask B is managed by Denmark, which has been responsible for collecting and organising background material. This work started in 1998. From the beginning, the idea was to organise the background material in a book called 'The Book of Tools', but during the course of preparation it became obvious that it would be an advantage to place the material on the Internet. An initial version of the material has been finished in the winter 1999/2000 and has been incorporated in IEA's Task 24 homepage on the Internet address: www.ieatask24.org. The Internet home page is up-dated by the Canadian participants in IEA task 24. The target group is partly new potential buyer groups and current buyer groups and their advisors.

This report summarizes recent findings on wind integration from the 16 countries participating in the International Energy Agency (IEA) Wind collaboration research Task 25 in 2012-2014. Both real experience and studies are reported. The national case studies address several impacts of wind power on electric power systems. In this report, they are grouped under long-term planning issues and short-term operational impacts. Long-term planning issues include grid planning and capacity adequacy. Short-term operational impacts include reliability, stability, reserves, and maximizing the value in operational timescales (balancing related issues). The first section presents variability and uncertainty of power system-wide wind power, and the last section presents recent wind integration studies for higher shares of wind power. Appendix 1 provides a summary of ongoing research in the national projects contributing to Task 25 in 2015-2017.

Development of a training simulator to operators of the IEA-R1 research reactor

International Nuclear Information System (INIS)

Carvalho, Ricardo Pinto de

2006-01-01

This work reports the development of a Simulator for the IEA-R1 Research Reactor. The Simulator was developed with Visual C++ in two stages: construction of the mathematics models and development and configuration of graphics interfaces in a Windows XP executable. A simplified modeling was used for main physics phenomena, using a point kinetics model for the nuclear process and the energy and mass conservation laws in the average channel of the reactor for the thermal hydraulic process. The dynamics differential equations were solved by using finite differences through the 4th order Runge- Kutta method. The reactivity control, reactor cooling, and reactor protection systems were also modeled. The process variables are stored in ASCII files. The Simulator allows navigating by screens of the systems and monitoring tendencies of the operational transients, being an interactive tool for teaching and training of IEA-R1 operators. It also can be used by students, professors, and researchers in teaching activities in reactor and thermal hydraulics theory. The Simulator allows simulations of operations of start up, power maneuver, and shut down. (author)

IEA-R1 research reactor: operational life extension and considerations regarding future decommissioning

International Nuclear Information System (INIS)

Frajndlich, Roberto

2009-01-01

The IEA-R1 reactor is a pool type research reactor moderated and cooled by light water and uses graphite and beryllium reflectors. The reactor is located at the Instituto de Pesquisas Energeticas e Nucleares (IPEN-CNEN/SP), in the city of Sao Paulo, Brazil. It is the oldest research reactor in the southern hemisphere and one of the oldest of this kind in the world. The first criticality of the reactor was obtained on September 16, 1957. Given the fact that Brazil does not have yet a definitive radioactive waste repository and a national policy establishing rules for the spent fuel storage, the institutions which operate the research reactors for more than 50 years in the country have searched internal solutions for continued operation. This paper describes the spent fuel assemblies and radioactive waste management process for the IEA-R1 reactor and the refurbishment and modernization program adopted to extend its lifetime. Some considerations about the future decommissioning of the reactor are also discussed which, in my opinion, might help the operating organization to make decisions about financial, legal and technical aspects of the decommissioning procedures in a time frame of 10-15 years(author)

1978-01-01

A theoretical model for the calculation of the radioactivity level in the pool surface of the research reactor IEA-RI (INSTITUTO DE ENERGIA ATOMICA, BRAZIL) is developed. The radioactivity is caused by radionuclides (Mainly 24 Na and 27 Mg) produced by nuclear reactions of neutrons with: a) oxygen of the water b); gaseous elements dissolved in water (Ar,N); c) structural materials of the fuel can. Considerations about expected radiation level after eventual increase of reactor power from 2 MW to 10 MW are also presented [pt

For the Danish solar heating industries it is interesting to discuss the domestic market possibilities and the export possibilities for solar heating cooling systems. The Danish solar heating sector also wants to participate in the international collaboration within IEA Solar Heating and Cooling Task 25 'Solar Assisted Air Conditioning of Buildings'. The Danish Energy Agency therefore has granted means for this project to discuss: The price of cooling for 3 different solar cooling methods (absorption cooling, desiccant cooling and ejector cooling); Market possibilities in Denmark and abroad; The advantages by Danish participation in IEA Task 25. The task has been solved through literature studies to establish status for the 3 technologies. It turned out that ejector cooling by low temperatures (85 deg. C from the solar collector) exists as pilot plants in relation to district heating, but is still not commercial accessible. Desiccant cooling, where the supplied heat has temperatures down to 55 deg. C is a well-developed technology. However only a handful of pilot plants with solar heating exists, and thus optimization relating to operation strategy and economy is on the experimental stage. Absorption cooling plants driven by solar heating are found in a large number in Japan and are also demonstrated in several other countries. The combination of absorption heating pump and solar heating is considered to be commercial accessible. Solar heating is interesting as heat source of to the exent that it can replace other sources of heat without the economy being depreciated. This can be the case in South Europe if: 1) oil or natural gas is used for heating; 2) a solar heating system already exists, e.g. for domestic water supply, and is installed so that the marginal costs by solar heating supply of the ventilation plant is reduced. All in all the above conditions mean that the market for solar heating for cooling is very limited in Europe, where almost

The IEA-R1 reactor of IPEN/CNEN-SP in Brazil is a pool type research reactor cooled and moderated by demineralized water and having Beryllium and Graphite as reflectors. In 1997 the reactor received the operating licensing for 5 MW. A new research reactor is being planned in Brazil to replace the IEA-R1 reactor. This new reactor, the Brazilian Multipurpose Reactor (RMB), planned for 30 MW, is now in the conception design phase. Low enriched uranium (LEU) (<20% {sup 235}U) UAl{sub x} dispersed in Al targets are being considered for production of Molybdenum-99 ({sup 99}Mo) by fission. Neutronic and thermal-hydraulics calculations were performed, respectively, to compare the production of {sup 99}Mo for these targets in IEA-R1 reactor and RMB and to determine the temperatures achieved in the UAl{sub x}-Al targets during irradiation. For the neutronic calculations were utilized the computer codes HAMMER-TECHNION, CITATION and SCALE and for the thermal-hydraulics calculations was utilized the computer code MTRCR-IEAR1. (author)

The place of digital technology on the IEA's energy road-maps

The International Energy Agency (IEA) has drafted road-maps for the next four decades in collaboration with public and private producers and consumers of energy. For each type of energy, these road-maps indicate the key elements for compliance with the objectives of the Paris Climate Agreement. They emphasize the role of digital technology, in particular smart grids, in the transition toward a more digital and more intelligent energy system. The conditions necessary for successfully transforming this sector are mapped out, while attention is called to the risks inherent in this transition

Nuclear energy in a low carbon future: updating the IEA/NEA nuclear technology road-map

International Nuclear Information System (INIS)

Paillere, H.; Cameron, R.; ); Tam, C.; )

2014-01-01

The Nuclear Technology road-map is one of 20 technology road-maps which the International Energy Agency (IEA) has published. The 2010 road-map, produced jointly by the IEA and the OECD Nuclear Energy Agency (NEA), came out in a year which saw 16 new construction starts, a number that had not been reached since 1985. The IEA's Energy Technology Perspectives (ETP) 'Blue Map' scenario, also published in 2010, projected at that time that the installed world nuclear capacity would need to reach 1200 GW (gross) by 2050 as part of a global effort to de-carbonise the electricity sector assuming least cost optimisation. The 'nuclear renaissance' then stalled for a number of reasons which include the consequences of the accident at the Fukushima Daiichi nuclear power plant in March 2011 on public acceptance and energy policies. The economic crisis that was already looming in 2010, as well as delays and cost overruns in the first Generation III new build projects in Europe also played a role in the significant drop in new projects. Finally, the US shale gas revolution and the potential role that unconventional oil and gas could play have also changed the prospects for nuclear development in many countries. Four years after the publication of the first road-map, the IEA and the NEA are updating the nuclear energy road-map, taking into account the recent challenges facing the development of this technology. The presentation of this paper will explain the process followed to update the road-map, through stakeholder engagement workshops that took place between January and April 2014. It will most importantly provide some insight into its contents and preliminary milestones and recommendations. The draft of the road-map will be peer-reviewed over the summer and will be published at the end of 2014. The vision developed in the road-map still relates to the contribution that nuclear energy can make to the de-carbonisation of the power system, described in

IPEN/CNEN-SP manufactures fuels to be used in its research reactor - the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil still does not have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP has conducted a fuel qualification program based on the use of uranium compounds (U 3 O 8 and U 3 Si 2 dispersed in Al matrix) internationally tested and qualified to be used in research reactors, and has attained experience in the technological development stages for the manufacturing of fuel plates, irradiation and non-destructive post-irradiation testing. Fuel elements containing low volume fractions of fuel in the dispersion were manufactured and irradiated successfully directly in the core of the IEA-R1. However, there are plans at IPEN/CNEN-SP to increase the uranium density of the fuels. Ten fuel miniplates (five containing U 3 O 8 -Al and five containing U 3 Si 2 -Al), with densities of 3.2 gU/cm 3 and 4.8 gU/cm 3 respectively, are being irradiated inside an irradiation device placed in a peripheral position of the IEA-R1 core. Non-destructive methods will be used to evaluate irradiation performance of the fuel miniplates after successive cycles of irradiation, by means: monitoring the reactor parameters during operation; periodic underwater visual inspection of fuel miniplates, eventual sipping test for fuel miniplates suspected of leakage and underwater measuring of the miniplate thickness for assessment of the fuel miniplate swelling.

IEA-R1 research reactor at the Instituto de Pesquisas Energeticas e Nucleares (Nuclear and Energy Research Institute) IPEN, Sao Paulo, Brazil is the largest power research reactor in Brazil, with a maximum power rating of 5 MWth. It is being used for basic and applied research in the nuclear and neutron related sciences, for the production of radioisotopes for medical and industrial applications, and for providing services of neutron activation analysis, real time neutron radiography, and neutron transmutation doping of silicon. IEA-R1 is a swimming pool reactor, with light water as the coolant and moderator, and graphite and beryllium as reflectors. The reactor was commissioned on September 16, 1957 and achieved its first criticality. It is currently operating at 4.5 MWth with a 60-hour cycle per week. In the early sixties, IPEN produced {sup 131}I, {sup 32}P, {sup 198}Au, {sup 24}Na, {sup 35}S, {sup 51}Cr and labeled compounds for medical use. During the past several years, a concerted effort has been made in order to upgrade the reactor power to 5 MWth through refurbishment and modernization programs. One of the reasons for this decision was to produce {sup 99}Mo at IPEN. The reactor cycle will be gradually increased to 120 hours per week continuous operation. It is anticipated that these programs will assure the safe and sustainable operation of the IEA-R1 reactor for several more years, to produce important primary radioisotopes {sup 99}Mo, {sup 125}I, {sup 131}I, {sup 153}Sm and {sup 192}Ir. Currently, all aspects of dealing with fuel element fabrication, fuel transportation, isotope processing, and spent fuel storage are handled by IPEN at the site. The reactor modernization program is slated for completion by 2015. This paper describes 58 years of operating experience and utilization of the IEA-R1 research reactor for research, teaching and radioisotopes production. (authors)

From shared data to sharing workflow: Merging PACS and teleradiology

International Nuclear Information System (INIS)

Benjamin, Menashe; Aradi, Yinon; Shreiber, Reuven

2010-01-01

Due to a host of technological, interface, operational and workflow limitations, teleradiology and PACS/RIS were historically developed as separate systems serving different purposes. PACS/RIS handled local radiology storage and workflow management while teleradiology addressed remote access to images. Today advanced PACS/RIS support complete site radiology workflow for attending physicians, whether on-site or remote. In parallel, teleradiology has emerged into a service of providing remote, off-hours, coverage for emergency radiology and to a lesser extent subspecialty reading to subscribing sites and radiology groups. When attending radiologists use teleradiology for remote access to a site, they may share all relevant patient data and participate in the site's workflow like their on-site peers. The operation gets cumbersome and time consuming when these radiologists serve multi-sites, each requiring a different remote access, or when the sites do not employ the same PACS/RIS/Reporting Systems and do not share the same ownership. The least efficient operation is of teleradiology companies engaged in reading for multiple facilities. As these services typically employ non-local radiologists, they are allowed to share some of the available patient data necessary to provide an emergency report but, by enlarge, they do not share the workflow of the sites they serve. Radiology stakeholders usually prefer to have their own radiologists perform all radiology tasks including interpretation of off-hour examinations. It is possible with current technology to create a system that combines the benefits of local radiology services to multiple sites with the advantages offered by adding subspecialty and off-hours emergency services through teleradiology. Such a system increases efficiency for the radiology groups by enabling all users, regardless of location, to work 'local' and fully participate in the workflow of every site. We refer to such a system as SuperPACS.

Measurements and calculation of reactivity in the IEA-R1 nuclear reactor

International Nuclear Information System (INIS)

Ferreira, P.S.B.

1988-01-01

Techniques and experimentals procedures utilized in the measurement of some nuclear parameters related to reactivity are presented. Measurements of reactivity coefficients, such as void, temperature and power, and control rod worth were made in the IEA-R1 Research Reactor. The techniques used to perform the measurements were: i) stable period (control rod calibration), ii) inverse kinetics (digital reactivity meter), iii) aluminium slab insertion in the fuel element coolant channels (void reactivity), iv) nuclear reactor core temperature changes by means of the changes in the coolant systems of reactor core (isothermal reactivity coefficient) and v) by making perturbation in the core through the control rod motions (power reactivity coefficient and control rod calibration). By using the computer codes HAMMER, HAMMER-TECHNION and CITATION, the experiments realized in the IEA-R1 reactor were simulated. From this simulation, the theoretical reactivity parameters were estimated and compared with the respective experimental results. Furthermore, in the second fuel load of Angra-1 Nuclear Power Station, the IPEN-CNEN/SP digital reactivity - meter were used in the lower power test with the aim to assess the equipment performance. Among several tests, the reacticity-meter were used in parallel with a Westinghouse analogic reativimeter-meter) to measure the heat additiona point, critical boron concentration, control rod calibration, isothermal and moderator reactivity coefficient. These tests, and the results obtained by the digital reactivity-meter are described. The results were compared with those obtained by Westinghouse analogic reactivity meter, showing excellent agreement. (author) [pt

With the purpose to check the performance of IEA Triple Axis Spectrometer of which construction was recently finished, dispersion relation curves for copper at room temperature have been messured. The frequencies of phonons propagating along the three major simmetry directions [xi00] [xixi0] and [xixixi] have been determined. The measurements were carried out operating the Triple Axis Spectrometer in the 'Q constant' mode at neutron energy loss. An excellent agreement could be observed between the results obtained in the present experiment and the accurate data for copper presented in the litterature. In such way, we can conclude that the IEA Triple Axis Spectrometer is in good operational conditions and able to perform original experiments. In this report an outline of the theory of the spectrometer operation and details on the experimental procedures for the case of a Triple Axis Spectrometer operating in the 'Q constant' mode are also presented [pt

The International Energy Agency Demand Side Management (IEA DSM) program is an international collaboration with 17 IEA member countries and the European Commission. The program aims to clarify and promote opportunities for DSM through load management, energy efficiency and strategic conservation. Task 13 of the program is charged with reviewing demand response resource (DRR) practices in various markets around the world and developing recommendations and tools for integrating DRR into regular market activities. The Ontario Power Authority (OPA), National Research Council (NRC) and CEA Technologies Inc. (CEATI) are leading participation in Task 13 in Canada. The team is currently collecting market information as well as creating tools to provide references to activities in other markets. This presentation reviewed the team's subtasks, which include: the development of DR market benchmarks and translation methods; the collection of DR consumer surveys and utilization methods; the creation of a DR market potential calculator to provide estimates for generating target marketing strategies; the creation of a valuation guide for technical users, administrators and regulators; a catalogue describing the technologies and systems that are available for use in DR programs; identifying market barriers; and the creation of a web portal that will be a virtual centre of excellence concerning DR methods, technologies and applications. DR programs in Norway, Finland, the Netherlands were also reviewed. refs., tabs., figs

BNFL does not agree with the IEA business prediction showing a decline in the share of electricity generated by nuclear power over the next 20 years. On the contrary BNFL believes that lifetime extension and continued new build will help maintain or even increase the share of electricity generated by nuclear power. One reason why new nuclear build programmes have been reduced is because existing reactors are operating for longer and at higher performance than ever before. As reactor lifetimes are extended new business opportunities will emerge concerning the upgrading of different systems from nuclear control systems to steam turbines. (A.C.)

Non-urgent accident and emergency department use as a socially shared custom: a qualitative study.

Science.gov (United States)

Keizer Beache, Simone; Guell, Cornelia

2016-01-01

We explored attitudes of non-urgent accident and emergency department (AED) patients in the middle-income healthcare setting Saint Vincent and the Grenadines (SVG) in the Caribbean to understand how and why they decide to seek emergency care and resist using primary care facilities. In 2013, we conducted 12 semistructured interviews with a purposive sample of non-urgent AED users from a variety of social backgrounds. Verbatim transcripts were analysed with a grounded theory approach. In this study, we found, first, that participants automatically chose to visit the AED and described this as a locally shared custom. Second, the healthcare system in SVG reinforced this habitual use of the AED, for example, by health professionals routinely referring non-urgent cases to the AED. Third, there was also some deliberate use; patients took convenience and the systemic encouragement into account to determine that the AED was the most appropriate choice for healthcare. We conclude that the attitudes and habits of the Vincentian non-urgent patient are major determinants of their AED use and are intricately linked to local, socially shared practices of AED use. Findings show that health services research should reconsider rational choice behaviour models and further explore customs of health-seeking. Published by the BMJ Publishing Group Limited.

This report describes the work performed within the first phase of IEA Task 29 Mexnext. In this IEA Task 29 a total of 20 organisations from 11 different countries collaborated in analysing the measurements which have been performed in the EU project 'Mexico'. Within this Mexico project 9 European institutes carried out a wind tunnel experiment in the Large Low Speed Facility (LLF) of the German Dutch Wind Facilities DNW on a rotor with a diameter of 4.5 m. Pressure distributions were measured at five locations along the blade along with detailed flow field measurements around the rotor plane using stereo PIV. As a result of the international collaboration within this task a very thorough analysis of the data could be carried out and a large number of codes were validated not only in terms of loads but also in terms of underlying flow field. The detailed pressure measurements along the blade in combination with the detailed flow field measurements gave a unique opportunity to better understand the response of a wind turbine to the incoming flow field. Deficiencies in modelling have been established and directions for model improvement can be given.

Sharing the dance -

In his recent works on daily face-to-face encounters, Zahavi claims that the phenomenon of sharing involves reciprocity. Following Zahavi’s line of thought, we wonder what exactly reciprocity amounts to and how the shared experience emerges from the dynamic process of interaction. By turning...... to the highly specialized field of elite sports dance, we aim at exploring the way in which reciprocity unfolds in intensive deliberate practices of movement. In our analysis, we specifically argue that the ongoing dynamics of two separate flows of movement constitute a shared experience of dancing together...

Estimative of core damage frequency in IPEN'S IEA-R1 research reactor due to the initiating event of loss of coolant caused by large rupture in the pipe of the primary circuit

International Nuclear Information System (INIS)

Hirata, Daniel Massami; Sabundjian, Gaiane; Cabral, Eduardo Lobo Lustosa

The National Commission of Nuclear Energy (CNEN), which is the Brazilian nuclear regulatory commission, imposes safety and licensing standards in order to ensure that the nuclear power plants operate in a safe way. For licensing a nuclear reactor one of the demands of CNEN is the simulation of some accidents and thermalhydraulic transients considered as design base to verify the integrity of the plant when submitted to adverse conditions. The accidents that must be simulated are those that present large probability to occur or those that can cause more serious consequences. According to the FSAR (Final Safety Analysis Report) the initiating event that can cause the largest damage in the core, of the IEA-R1 research reactor at IPEN-CNEN/SP, is the LOCA (Loss of Coolant Accident). The objective of this paper is estimate the frequency of the IEA-R1 core damage, caused by this initiating event. In this paper we analyze the accident evolution and performance of the systems which should mitigate this event: the Emergency Coolant Core System (ECCS) and the isolated pool system. They will be analyzed by means of the event tree. In this work the reliability of these systems are also quantified using the fault tree. (author)

From Oil Crisis to Climate Change. Understanding CO2 Emission Trends in IEA Countries

International Nuclear Information System (INIS)

Unander, F.

2003-11-01

OECD CO2 emissions from fuel combustion increased 13% between 1990 and 2001. This signals an important shift since, over the 1973 to 1990 period, emissions only increased by 3.4%. As a result, CO2 emissions from energy use (fuel combustion) contributed 81.1% of total OECD greenhouse gas emissions in 2001 compared to 77.7% in 1990. As these figures make clear, reducing CO2 emissions from fuel combustion constitutes a key challenge to combat climate change. Developing and successfully implementing the most efficient policies for reducing CO2 emissions requires a good understanding of how factors such as income, prices, demography, economic structure, lifestyle, climate, energy efficiency and fuel mix affect energy use and resulting CO2 emissions. This paper presents selected results from the analysis of CO2 developments included in the IEA publication 'From Oil Crisis to Climate Challenge: 30 Years of Energy Use in IEA Countries'. The paper gives a brief overview of aggregate CO2 emission trends and of how recent developments in selected IEA countries compare to emissions levels implied by the Kyoto targets. A deeper understanding of the aggregate trends is provided by showing results from a decomposition analysis and by discussing developments in key end-use sectors. The full publication presents a more detailed analysis of how various factors have shaped energy use patterns and CO2 emissions since 1973. The analysis draws on a newly developed database with detailed information on energy use in the manufacturing, household, service and transport sectors. The database represents the most disaggregated information available on a consistent basis across countries and sectors. The study uses quantitative measures to illustrate the forces that drive or restrain energy use. These measures - or indicators - include: activities such as manufacturing output or heated-floor-area of homes; structural developments such as changes in manufacturing output mix or changes in the

Epistemic companions: shared reality development in close relationships.

Science.gov (United States)

Rossignac-Milon, Maya; Higgins, E Tory

2018-01-11

We propose a framework outlining the development of shared reality in close relationships. In this framework, we attempt to integrate disparate close relationship phenomena under the conceptual umbrella of shared reality. We argue that jointly satisfying epistemic needs-making sense of the world together-plays an important but under-appreciated role in establishing and maintaining close relationships. Specifically, we propose that dyads progress through four cumulative phases in which new forms of shared reality emerge. Relationships are often initiated when people discover Shared Feelings, which then facilitate the co-construction of dyad-specific Shared Practices. Partners then form an interdependent web of Shared Coordination and ultimately develop a Shared Identity. Each emergent form of shared reality continues to evolve throughout subsequent phases, and, if neglected, can engender relationship dissolution. Copyright © 2018 Elsevier Ltd. All rights reserved.

Short-term objectives of the IEA Bioenergy Task 40 'Sustainable International Bio-energy Trade: Securing Supply and Demand' are amongst other objectives to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands and is an extended update of previous reports (2005 and 2006)

A review of the IEA/NEA Projected Costs of Electricity – 2015 edition

International Nuclear Information System (INIS)

Khatib, Hisham

2016-01-01

The IEA/NEA recently issued their eighth edition of the Study on the “Projected Costs of Generating Electricity” – 2015 edition. The Study is mainly concerned with calculating the levelised cost of electricity (LCOE). The LCOE calculations are based on a levelised average life time cost approach using the discounted cash flow (DCF) method. The analysis was this year, and for the first time, performed using three discount rates (3%, 7%, and 10%). The LCOE can serve as a tool for calculating the cost of different generation technologies. However the Study's usefulness is affected by its narrow base of a limited set of countries that are not necessarily representative. It ignored the negative role of subsidies and did not provide a methodology for selective application of the discount rates and costing of carbon. The global power generation scene is changing. Generation growth in OECD countries has become very limited; simultaneously there is rapid growth of varying renewables (VRE) generation which needs special criteria for assessing its system cost. All this demands a rethinking of the application and usefulness of the LCOE in future generation planning. - Highlights: • LCOE is a useful tool for economics of generation technologies. • The IEA/NEA study did not cover fully the required criteria for assessment. • It ignored interpretation of: the discount rate, carbon costing and subsidies. • The world energy scene is changing, this requires reassessment of LCOE.

Energy Policies of IEA Countries: Italy [Italian Version, Executive Summary

Energy Technology Data Exchange (ETDEWEB)

NONE

2010-07-01

This review analyses the energy challenges facing Italy and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Italy towards a more sustainable energy future. The Italian government has made substantial progress in a number of sectors since the last IEA in-depth energy policy review in 2003. The success of the green certificate and white certificate schemes and continued reform of the electricity and natural gas supply markets are just a few examples and build on the recommendations contained in the previous review. Nonetheless, many challenges remain. Italy recognises the need to diversify its energy supply portfolio to reduce its heavy dependence on fossil fuels and electricity imports, and to decrease its growing greenhouse gas emissions. In 2008, the government announced its intention to recommence the countrys nuclear power program and start building a new nuclear power plant by 2013. To do so, Italy must first develop an efficient process for identifying critical energy infrastructure, including nuclear power, and subjecting it to an effective, streamlined siting and permitting process. Italy will face another major challenge in complying with Europe’s new climate and energy package, particularly in relation to renewable energy and emissions targets. Italy must step up efforts to comply with its new responsibilities, specifically by developing and putting in place a comprehensive climate change strategy for the years until 2020. In mid-2009, the legislature enacted a comprehensive new law that will facilitate the emergence of a robust long-term energy policy. The government must respond to this opportunity and elaborate, with industry, a comprehensive long-term strategy for the development of the energy sector. This review analyses the energy challenges facing Italy and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Italy towards a more

CSP electricity cost evolution and grid parities based on the IEA roadmaps

International Nuclear Information System (INIS)

Hernández-Moro, J.; Martínez-Duart, J.M.

2012-01-01

The main object of this paper consists in the development of a mathematical closed-form expression for the evaluation, in the period 2010–2050, of the levelized costs of energy (LCOE) of concentrating solar power (CSP) electricity. For this purpose, the LCOE is calculated using a life-cycle cost method, based on the net present value, the discounted cash flow technique and the technology learning curve approach. By this procedure, the LCOE corresponding to CSP electricity is calculated as a function of ten independent variables. Among these parameters, special attention has been put on the evaluation of the available solar resource, the analysis of the IEA predicted values for the cumulative installed capacity, the initial (2010) cost of the system, the discount and learning rates, etc. One significant contribution of our work is that the predicted evolution of the LCOEs strongly depend, not only on the particular values of the cumulative installed capacity function in the targeted years, but mainly on the specific curved time-paths which are followed by this function. The results obtained in this work are shown both graphically and numerically. Finally, the implications that the results could have in energy planning policies and grid parity calculations are discussed. - Highlights: ► A mathematical closed expression has been developed for calculating the evolution of CSP electricity costs. ► Our technique for the prediction of CSP electricity costs and grid parities is based on IEA Roadmaps. ► The time-table (2010–2050) of cumulative installed CSP capacity is key to electricity cost predictions. ► CSP grid parities can occur within next decade for sites with proper solar resources.

Study and project of the new rack with boron for storage of fuel elements burned in the IEA-R1 research reactor

International Nuclear Information System (INIS)

Rodrigues, Antonio Carlos Iglesias; Madi Filho, Tufic; Silva, Davilson Gomes da

The IEA-R1 research reactor works 40h weekly with 4.5 Mw power. The storage rack for spent fuel elements has less than half of its initial capacity. Under these conditions (current conditions of reactor operation 32h weekly will have 3 spend fuel by year, then, approximately 3 utilization rate Positions/year). Thus, we will have only about six years of capacity for storage. Whereas the desired service life of the IEA-R1 is at least another 20 years, it will be necessary to increase the storage capacity of spent fuel. Hence, it is necessary to double the wet storage capacity (storage in the IEA-R1 reactor's pool). After reviewing the literature about materials available for use in the construction of the new storage rack with absorber of neutrons, the BoralcanTM (manufactured by 3TMhis) was chosen due to its properties. This work presents studies: (a) for the construction of new storages racks with double of the current capacity using the same place of current storages racks and (b) criticality analysis using the MCNP-5 code. Two American Nuclear Data Library were used: ENDF / B-VI and ENDF / B-VII, and the results obtained for each data bases were compared. These analyzes confirm the possibility of doubling the storage capacity of fuel elements burned in the same place occupied by the current storage rack attending to the IEA-R1 reactor needs and attending the safety requirements according to the National Nuclear Energy Commission - CNEN and the International Atomic Energy Agency (IAEA). To calculate the k eff were considered new fuel elements (maximum possible reactivity) used in full charge of the storage rack. With the results obtained in the simulation we can conclude that doubling the amount of racks for spent fuel elements are complied with safety limits established in the IAEA standards and CNEN of criticality (keff < 0.95).

In 1999, the management of the IEA-R1 Research Reactor (pool type - 5 MWth), located at IPEN/CNEN-SP, started the evaluation of the Reactor Pool Water Retreatment System to identify operational aspects, which could compromise the operators safety. The purpose was to identify and propose enhancements to the system which would be installed to substitute for the existing one. This process was conducted through a qualitative study of the system in operation. This study was carried out by a team composed of specialists in reactor operation, systems maintenance and radiological protection, and one safety analyst. The study consisted, basically, in local inspections to verify the physical and operational conditions of each equipment / component as well as aspects related to maintenance activities of the system. The process control and the operator procedures associated with the retreatment of the reactor pool water were also reviewed. The methodology adopted to develop the study was based in process hazard analysis technique named Safety Checklist. This paper presents a summary of this study and the main results obtained. Some operational and safety problems identified, the prevention and/or correction means to avoid them, and the recommendations and suggestions that have been implemented to the new design of the IEA-R1 Reactor Water Retreatment System, whose installation was concluded in 2003, are also presented.

2013-05-01

Full Text Available BACKGROUND The laboratory overuse is widely prevalent in hospital practice, mostly in the emergency care. Reasons for excessive and inappropriate test-ordering include defensive behaviour and fear or uncertainty, lack of experience, the misuse of protocols and guidelines, “routine” and local attitudes, inadequate educational feedback and clinician’s unawareness about the cost of examinations and their related implications. AIM OF THE STUDY AND METHODS The primary target of our working group was to reduce inappropriate ordering on a urgent basis test, implementing further examinations not yet previewed in the hospital panel of the available urgencies, according to the evidence based diagnosis concept. The secondary goal was to indicate strategies of re-engineering of the processes, improving turnaround time in the laboratory management of emergencies. After evaluating, as first intervention, the more reliable sources for practice guidelines, systematic reviews and RCTs, the committee further discussed main topics with in-hospital stakeholders, selected from Emergency, Internal Medicine and Surgery Depts. The working group, in many subsequent audits, tried to obtain a systematic feed back with all involved professionals. RESULTS After reviewing literature’s evidence, the board constrained testing options by defining the basic emergency laboratory panel tests (blood type, hemogram, blood urea nitrogen, plasma creatinine, glucose, sodium, potassium, chloride, osmolarity, CRP, bicarbonate, CPK, creatine phosphokinase-MB, myoglobin, troponin, BNP and NT-proBNP, PT-INR, PTT, D-dimer, beta- HCG, biochemical urinalysis etc.. As final result, the proposed tests reduced the overall number of inappropriate investigations and increased, with newer and updated tests, the available panel for critical patients. DISCUSSION A collegiate review of data reporting, in-hospital deepening of problems and the inter- professional discussion of the evidences

Solar heating cooling. Preparation of possible participation in IEA, Solar Heating Cooling Task 25

International Nuclear Information System (INIS)

2001-03-01

For the Danish solar heating industries it is interesting to discuss the domestic market possibilities and the export possibilities for solar heating cooling systems. The Danish solar heating sector also wants to participate in the international collaboration within IEA Solar Heating and Cooling Task 25 'Solar Assisted Air Conditioning of Buildings'. The Danish Energy Agency therefore has granted means for this project to discuss: The price of cooling for 3 different solar cooling methods (absorption cooling, desiccant cooling and ejector cooling); Market possibilities in Denmark and abroad; The advantages by Danish participation in IEA Task 25. The task has been solved through literature studies to establish status for the 3 technologies. It turned out that ejector cooling by low temperatures (85 deg. C from the solar collector) exists as pilot plants in relation to district heating, but is still not commercial accessible. Desiccant cooling, where the supplied heat has temperatures down to 55 deg. C is a well-developed technology. However only a handful of pilot plants with solar heating exists, and thus optimization relating to operation strategy and economy is on the experimental stage. Absorption cooling plants driven by solar heating are found in a large number in Japan and are also demonstrated in several other countries. The combination of absorption heating pump and solar heating is considered to be commercial accessible. Solar heating is interesting as heat source of to the extent that it can replace other sources of heat without the economy being depreciated. This can be the case in South Europe if: 1) oil or natural gas is used for heating; 2) a solar heating system already exists, e.g. for domestic water supply, and is installed so that the marginal costs by solar heating supply of the ventilation plant is reduced. All in all the above conditions mean that the market for solar heating for cooling is very limited in Europe, where almost everybody are

Neutronradiography of several materials have been obtained at the IEA-R1 Nuclear Research Reactor (IPEN-CNEN/SP), by means of two conversion techniques: a) (n, α) at the beam-hole n 0 3 where a collimated thermal neutron beam, exposure area 4 cm x 8cm and flux at the sample 10 5 n/s cm 2 is obtained. The film used was the CN-85 cellulose nitrate coated with lithium tetraborate (conversor). The time irradiation of the film was 15 minutes and in following was eteched during 30 minutes in a NaOH(10%) aqueous solution at a constant temperature of 60 0 C.; b) (n,γ) by using an experimental arrangement installed in the botton of the pool of the reactor. The flux of the collimated neutron beam is 10 5 n/s/cm 2 at the sample and the conversion is made by means of a dysprozium sheet. The film used was Kodak T-5. The irradiation and the transfering time was 2 hours and 20 hours respectively. (author) [pt

Energy policies of IEA countries: Turkey 1997 review

NONE

1997-12-31

This IEA report provides a comprehensive in-depth assessment of the energy policies of Turkey, including recommendations on future policy developments. The report highlights the rapid increase in Turkey`s energy consumption and the large investments needed to meet the demand growth. Turkey has sought to attract private inward investment in the energy sector, in particular in electricity, through build-own-operate and build-operate-transfer schemes and transfers of operating rights. Turkey needs to set up a stable legal framework to continue this policy. It needs to push forward with market reforms, as well as to create a level playing field for competition, with energy prices reflecting the true costs of various fuels. Natural gas consumption is also expected to continue to increase. The new regulatory framework should be designed to encourage more rapid increase in the use of gas and more corresponding investments. Turkey is situated near the Caspian Sea, where natural gas and oil production are expected to increase substantially. The report describes projects for oil and natural gas pipelines. 33 figs., 31 tabs., 4 apps.

What to Share and Why to Share? A Case Study of CrossBoundary Information Sharing in Taiwan e-Government

Directory of Open Access Journals (Sweden)

Tung-Mou Yang

2013-06-01

Full Text Available In the public sector, cross-boundary information sharing has been an important theme among governmental collaboration and is critical to organizational efficiency and performance. This research explores the types and characteristics of shared information and the intended purposes of information sharing. In the case study, the cross-boundary shared information can be abstracted into five fundamental types: the collected raw data, the value-added information, the administration oriented information, the administration-oriented knowledge, and the domain-oriented knowledge. Another framework is proposed to conceptualize the purposes of interagency information sharing. The identified seven purposes are administrative work, information search and verification, information aggregation, business process chain, innovative service, experience-based knowledge sharing, and crisis and emergency. The seven purposes do not mean to be an exhaustive list but to provide an initial conceptualization to perceive the functionalities and roles that cross-boundary information sharing plays among government agencies. The two proposed frameworks can help both researchers and practitioners perceive and clarify the fundamental part of cross-boundary information sharing in the public sector. The finding of this research is also expected to enrich the current information-sharing theories and to contribute to the current e-Government literature from an international perspective.

Oil and Gas Emergency Policy: Japan 2013 update

2013-06-01

Oil remains the most significant energy source in Japan, accounting for some 45% of the country’s total primary energy supply (TPES) in 2011. Japan’s oil demand steadily decreased from 5.71 mb/d in 1997 to 4.47 mb/d in 2010. However, its oil demand increased to 4.48 mb/d in 2011 and 4.73 mb/d in 2012 due to the Great East Japan Earthquake in March 2011 and its subsequent impacts. The transport sector represented around 38% of total consumption in 2010, while the industry sector accounted for 30%. A significant proportion of the industry sector’s oil demand comes from the chemical industry. Of the 4.8 mb/d of oil imported by Japan in 2012, 3.5 mb/d consisted of crude oil, 209 kb/d of NGLs and feedstocks, and some 1.2 mb/d of refined products. About 83% of Japan’s crude oil imports in 2012 came from the Middle East. The country has 27 operational refineries with a total crude distillation capacity of around 4.5 mb/d. Japan meets its 90-day stockholding obligation to the IEA by holding government emergency stocks and by placing a minimum stockholding obligation on industry. JOGMEC’s primary role is to manage public stocks under the Oil Stockpiling Act, while industry (refineries, specified distributors and importers) is obliged to hold the equivalent of 70 days of their daily imports, sales or refinery production, based on the average of the previous 12 months. The public stocks mostly consist of crude oil, but the Administration has expanded its emergency inventory to include four categories of refined products - gasoline, kerosene, fuel oil and diesel oil. Japan held some 591 million barrels (mb) of oil stocks at the end of January 2013, equating to 166 days of 2011 net-imports (92 days of government stocks and 74 days of industry stocks). Around 72% of total stocks were held in the form of crude oil. Japan has consistently met its minimum IEA stockholding obligation. The share of natural gas in the country’s TPES increased significantly from 17% in 2010

Application of non-destructive methods for qualification of the U3O8-Al and U3Si2-Al dispersion fuels in the IEA-R1 Reactor

Silva, Jose Eduardo Rosa da

2011-01-01

IPEN/CNEN-SP manufactures fuels to be used in its nuclear research reactor - the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil doesn't have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP has conducted a fuel qualification program based on the use of uranium compounds, internationally tested and qualified to be used in research reactors, and has gotten experience in the technological development stages for the manufacturing of fuel plates, irradiation and non-destructive post-irradiation testing. Fuel elements containing low volume fractions of fuel in the dispersion were manufactured and irradiated successfully directly in the core of the IEA-R1. However, there are plans to increase the uranium density of these fuels. The objective of this thesis work was to study and to propose a set of non-destructive methods to qualify the dispersions fuels U 3 O 8 -Al e U 3 Si 2 -Al with high uranium density produced at IPEN/CNEN-SP. For that, the irradiation resources in the IEA-R1, and the application of non-destructive methods in the reactor pool available in the Institution were considered. The proposal is to specify, manufacture and irradiate fuel mini plates in IEA-R1 at the maximum densities, qualified internationally, and to monitor their general conditions during the period of irradiation, using non-destructive methods in the reactor pool. In addition to the non-destructive visual inspection and sipping methods, already used at the Institution, the infrastructure for dimensional sub-aquatic testing to evaluate the swelling of irradiated fuel mini plates was completed. The analyses of the results will provide means to assess and decide whether or not to continue with the irradiation of mini plates, until the desired burnup for the irradiation tests at IEA-R1 are reached.

Norwegian contribution to the IEA Annex 24 - Absorption Machines for Heating and Cooling; IEA annex 24. Absorpsjonsmaskin for oppvarming og kjoeling

Energy Technology Data Exchange (ETDEWEB)

Grandum, Svein

2000-01-01

This report summarizes the Norwegian contribution to the IEA Annex 24 - Absorption Machines for Heating and Cooling in Future Energy Systems. Thermally operated heat pumps and coolers have not been widely used in Norway. They are not economically competitive compared to compression heat pumps because of Norway's cheap hydroelectric power. If the present trend in Norway's use of electricity persists, Norway will soon be dependent on imported electric power. This calls for measures to reduce the consumption of electricity, and the role of absorption heat pumps will be of increasing importance, especially for cooling purposes. For larger commercial buildings that require climate cooling, absorption coolers based on waste heat may have a good total economy. Industrial processes that have an excess of heat at a high temperature and which need cooling, may profit from the use of this type of cooler. Information dissemination is important for efficient use of this technology. The research work done at Institute of energy technology, Kjeller, Norway, is an important contribution to this end.

After a Conceptual Design Activity (CDA) study on an International Fusion Material Irradiation Facility (IFMIF) has been launched under the auspices of the IEA, working groups and relevant tasks have been defined and agreed in an IEA-workshop that was held September 26-29 1994 at Karlsruhe. For the Test Cell System 11 tasks were identified which can be grouped into the three major fields neutronics, test matrix/users and test cell engineering. In order to discuss recently achieved results and to coordinate necessary activities for an effective design integration, a technical workshop on the Test Cell System was initiated. This workshop was organized on July 3-6 1995 by the Institute for Materials Research I at the Forschungszentrum Karlsruhe and attended by 20 specialists working in the fields neutronics, fusion materials R and D and test cell engineering in the European Union, Japan, and the United States of America. The presentations and discussions during this workshop have shown together with the elaborated lists of action items, that has been achieved in all three fields, and that from the future IFMIF experimental program for a number of materials a database covering widerspread loading conditions up to DEMO-reactor relevant end-of-life damage levels can be expected.

Energy policies of IEA Countries. The Netherlands 1996 review

International Nuclear Information System (INIS)

1996-01-01

As part of the IEA's on-going analysis of Member countries' energy policies, this review assess the Netherlands and offers recommendations taking account of major reforms announced by the Dutch Government in December 1995. The prominence of environmental objectives in Dutch energy policy and the widespread use of voluntary long-term agreements with industry provide constructive lessons for other countries. Targets for energy efficiency and renewability are especially ambitious. Moreover, the Dutch Government has made an important contribution to environmental policy by striving for a combination of market liberalization and a sustainable energy economy. The review recommends that market reforms be further developed, if necessary in the context of developments in European energy market policy. Gas pricing and a tendency for over-capacity to develop in the electricity sector are particular areas of discussion in the report. The review also draws attention to potentially high economic costs which may arise form energy-environment policies and affect the competitiveness of Dutch industry. (author). 18 figs., 13 tabs

Results are presented from the Data Curation Profiles project research, on who is willing to share what data with whom and when. Emerging from scientists' discussions on sharing are several dimensions suggestive of the variation in both what it means 'to share' and how these processes are carried out. This research indicates that data curation services will need to accommodate a wide range of subdisciplinary data characteristics and sharing practices. As part of a larger set of strategies emerging across academic institutions, institutional repositories (IRs) will contribute to the stewardship and mobilization of scientific research data for e-Research and learning. There will be particular types of data that can be managed well in an IR context when characteristics and practices are well understood. Findings from this study elucidate scientists' views on 'sharable' forms of data-the particular representation that they view as most valued for reuse by others within their own research areas-and the anticipated duration for such reuse. Reported sharing incidents that provide insights into barriers to sharing and related concerns on data misuse are included.

IPEN’s research reactor, IEA-R1, an open pool type research reactor moderated and cooled by light water. High quality water is a key factor in preventing the corrosion of the spent fuel stored in the pool. Leaching of radionuclides from the corroded fuel cladding may be prevented by an efficient water treatment and purification system. However, as a safety management policy, IPEN has adopted a water chemistry control which periodically monitors the levels of uranium (U) and silicon (Si) in the pool’s reactor, since IEA-R1 employs U3Si2-Al dispersion fuel. An analytical method was developed and validated for the determination of uranium and silicon by ICP OES. This work describes the validation process, in a context of quality assurance, including the parameters selectivity, linearity, quantification limit, precision and recovery.

Characterization of cartridge filters from the IEA-R1 Nuclear Reactor

International Nuclear Information System (INIS)

2015-01-01

The management of radioactive waste ensures safety to human health and the environment nowadays and for the future, without overwhelming the upcoming generations. The primary characterization of radioactive waste is one of the main steps in the management of radioactive waste. This step permits to choose the best treatment for the radioactive waste before forwarding it to its final disposal. The aim of the present work is the primary characterization of cartridge filters from the IEA-R1 nuclear reactor utilizing gamma-ray spectrometry, and the method of Monte Carlo for calibration. The IEA-R1 is located in the Nuclear and Energy Research Institute (IPEN - CNEN) in the city of Sao Paulo, Brazil. Cartridge filters are used for purification of the cooling water that is pumped through the core of the pool type nuclear research reactors. Once worn out, these filters are replaced and then become radioactive waste. Determination of the radioactive inventory is of paramount importance in the management of such radioactive waste, and one of the main methods for doing so is the gamma-ray spectrometry, which can identify and quantify high energy photon emitters. The technique chosen for the characterization of radioactive waste in the present work is the gamma-ray spectrometry with High purity Germanium (HPGe) detectors. From the energy identified in the experimental spectrum, three radioisotopes were identified in the cartridge filter: 108m Ag, 110m Ag, 60 Co. For the estimated activity of the filter, the calibration in efficiency was made utilizing the MCNP4C code of the Monte Carlo method. Such method was chosen because there is no standard source available in the same geometry of the cartridge filter, therefore a simulation had to be developed in order to reach a calibration equation, necessary to estimate the activity of the radioactive waste. The results presented an activity value in the order of MBq for all radioisotopes. (authors)

2009-12-15

Despite creating a plethora of national and international regulations and voluntary programmes to improve energy efficiency, countries are far from achieving full energy efficiency potential across all sectors of the economy. One major challenge, among numerous barriers, is policy implementation. One strategy that many national governments and international organisations have used to address the implementation issue is to engage regional and local authorities. To that end, many programmes have been created that foster energy efficiency action and collaboration across levels of government. The aim of this report is to identify trends and detail recent developments in multi-level governance in energy efficiency (MLGEE). By sharing lessons learned from daily practitioners in the field, the IEA hopes energy efficiency policy makers at all levels of government will be able to identify useful multilevel governance (MLG) practices across geographical and political contexts and use these to design robust programmes; modify existing programmes, and connect and share experiences with other policy makers in this field.

The institute is recognized as a national leader in nuclear research and development (R and D), including the areas of reactor operation, radiopharmaceuticals, industrial and laboratory applications, materials science and laser technologies and applications. IPEN's main facility is the IEA-R1, nuclear research reactor (NRR), today, the only one in Brazil with a power level suitable for applications in physics, chemistry, biology and engineering. Some radioisotopes are also produced in IEA-R1, for medical and other applications. A common problem faced in the IEA-R1 maintenance is instrumentation obsolescence; spare parts are no more available, because of discontinued production, and an updating program is mandatory, aiming at modernization of old-aged I and C systems. In the presented context, an electronic system is here proposed, as a replacement for the reactor safety (shim) rods assembly position indicator, based on an open-source physical computing platform called Arduino, which includes a simple microcontroller board and a software-code development environment. A mathematical algorithm for the synchro-motor signal processing was developed, and the obtained resolution was better than 1.5%. (author)

2005-01-01

In 1999, the management of the IEA-R1 Research Reactor (pool type - 5 MWth), located at IPEN/CNEN-SP, started the evaluation of the Reactor Pool Water Retreatment System to identify operational aspects, which could compromise the operators safety. The purpose was to identify and propose enhancements to the system which would be installed to substitute for the existing one. This process was conducted through a qualitative study of the system in operation. This study was carried out by a team composed of specialists in reactor operation, systems maintenance and radiological protection, and one safety analyst. The study consisted, basically, in local inspections to verify the physical and operational conditions of each equipment / component as well as aspects related to maintenance activities of the system. The process control and the operator procedures associated with the retreatment of the reactor pool water were also reviewed. The methodology adopted to develop the study was based in process hazard analysis technique named Safety Checklist. This paper presents a summary of this study and the main results obtained. Some operational and safety problems identified, the prevention and/or correction means to avoid them, and the recommendations and suggestions that have been implemented to the new design of the IEA-R1 Reactor Water Retreatment System, whose installation was concluded in 2003, are also presented.

Sharing killed the AVMSD star: the impossibility of European audiovisual media regulation in the era of the sharing economy

2016-06-01

Full Text Available The paper focuses on the challenges that the ‘sharing economy’ presents to the updating of the European Union’s (EU Audiovisual Media Service Directive (AVMSD, part of the broader Digital Single Market (DSM strategy of the EU. It suggests that the convergence of media markets and the emergence of video-sharing platforms may make the existing regulative tradition obsolete. It demonstrates an emergent need for regulatory convergence – AVMSD to create equal terms for all technical forms of content distribution. It then shows how the operational logic of video-sharing platforms undermines the AVMSD logic aimed at creating demand for professionally produced European content – leading potentially to the liberalisation of the EU audiovisual services market. Lastly, it argues that the DSM strategy combined with sharing-related network effects may facilitate the evolution of the oligopolistic structure in the EU audiovisual market, potentially harmful for cultural diversity.

Highlights: • A set of advanced system thermal hydraulic codes are benchmarked against IFA of IEA-R1. • Comparative safety analysis of IEA-R1 reactor during LOFA by 7 working teams. • This work covers both experimental and calculation effort and presents new out findings on TH of RR that have not been reported before. • LOFA results discrepancies from 7% to 20% for coolant and peak clad temperatures are predicted conservatively. - Abstract: In the framework of the IAEA Coordination Research Project on “Innovative methods in research reactor analysis: Benchmark against experimental data on neutronics and thermal hydraulic computational methods and tools for operation and safety analysis of research reactors” the Brazilian research reactor IEA-R1 has been selected as reference facility to perform benchmark calculations for a set of thermal hydraulic codes being widely used by international teams in the field of research reactor (RR) deterministic safety analysis. The goal of the conducted benchmark is to demonstrate the application of innovative reactor analysis tools in the research reactor community, validation of the applied codes and application of the validated codes to perform comprehensive safety analysis of RR. The IEA-R1 is equipped with an Instrumented Fuel Assembly (IFA) which provided measurements for normal operation and loss of flow transient. The measurements comprised coolant and cladding temperatures, reactor power and flow rate. Temperatures are measured at three different radial and axial positions of IFA summing up to 12 measuring points in addition to the coolant inlet and outlet temperatures. The considered benchmark deals with the loss of reactor flow and the subsequent flow reversal from downward forced to upward natural circulation and presents therefore relevant phenomena for the RR safety analysis. The benchmark calculations were performed independently by the participating teams using different thermal hydraulic and safety

Slovakia has implemented impressive energy reforms over the recent past, a unique performance in Central and Eastern Europe. The 2000 energy policy prioritised market reforms and sectoral policies, notably on energy security and environment, in order to comply with EU requirements, which were largely met at the time of the country’s EU accession in 2004. Also, Slovakia established new regulations, notably cost reflective pricing enforced by an independent energy regulator, thereby attracting significant foreign direct investment. Notably, this rapid transition has occurred without disruption in this key energy transit country. New challenges ahead include strengthening energy security by diversification, opening energy markets and integrating them into the EU, strongly increasing energy efficiency to offset the high economic burden of energy prices and to help better controlling pollution and CO2 emissions in line with EU and international obligations. This review analyses the Slovak energy sector and policies, and provides recommendations for the government. It is a comprehensive assessment of what constitutes a remarkable case study of effective energy reforms in an economy in transition, which has applied for IEA membership.

This master thesis presents a study to verify the impact of the uranium concentration reduction in the side plates of the reactor IEA-R1 fuel elements on the neutronic and thermal-hydraulic analyses. To develop such study, a previous IPEN-CNEN/SP research was reproduced by simulating the fuel elements burn-up, with side plate uranium density reduced to 50, 60 and 70% of the standard fuel element plates. This research begins with the neutronic analysis using the computer code HAMMER and the first step consists in the calculation of the cross section of all materials presented at the reactor core, with their initial concentration; the second step consists in the calculation of the fast and thermal neutron group fluxes and power densities for fuel elements using the computer code CITATION. HAMMER output data is used as input data. Once the neutronic analysis is finished and the most critical fuel elements with highest power density have been defined, the thermal-hydraulics analysis begins. This analysis uses MCTR-IEA-R1 thermal-hydraulics model, which equations are solved by commercial code EES. Thermalhydraulics analysis input is the power density data calculated by CITATION: it is considered the highest power density on each fuel element, where there is a higher energy release and, consequently, higher temperatures. This data is used on energy balance equations to calculate temperatures on critical fuel element regions. Reactor operation comparison for three different uranium densities on fuel side plates is presented. Uranium density reduction contributes to the cladding surface temperature to remain below the established limit, as reactor operation safety requirement and it does not affect significantly fuel element final burn-up nor reactor reactivity. The reduction of uranium in the side plates of the fuel elements of the IEA-R1 showed to be a viable option to avoid corrosion problems due to high temperatures. (author)

Application of TEMPPC code to the IEA-R1 nuclear reactor core hydrothermal calculations operating at 2 MW for determining the minimal coolant flow

A thermohydraulic study of the IEA-R1 nuclear reactor core on steady-state operating condition and forced convection, is presented. The objective of this calculation is to obtain the minimal flow rate of coolant necessary at the reactor core, limited by the temperature associated to the beginning of nucleate boiling over the fuel plates at a normal operating power (2MW) for a certain inlet coolant temperature. The coolant system safety level is also calculated in this paper, which is divided in three steps: thermohydraulic calculation, without using the uncertainty factors and, after that, considering these factor by two methods: the statistical and the conventional ones. Whichever the method accepted, the results obtained by the program TEMPPC show a great safety margin with respect to the termohydraulic parameters from the IEA-R1 nuclear reactor. (Author) [pt

Participation was implemented to the IEA/DSM task VI as the demonstrative investigation of a new load leveling method. The DSM strategy is a means to achieve the public objectives of wide range, wherein the DSM mechanism is important, that can obtain accurate and useful information in competitive markets. Consumer protecting activities have close relation with general information needs. A financial incentive mechanism is also necessary to support nurturing of business organizations and new ESCO industries. A market forming mechanism using the DSM can solve the problem of disagreement in the incentives (for example, private profit of electric power companies and the public nature of the government). These include system plans considering the DSM, setting of upper limit in the profit, demand side bidding, and green charge institution. It is important to utilize affluent findings and means used in the past and utilize each mechanism to meet the needs for public benefit at the present and in the future, while structuring an electric power business structure incorporating the DSM. The DSM promoting mechanisms in each country were classified and put into order of regulations, supports, funds, and markets. (NEDO)

2000-01-01

An analysis of technological catastrophic events that took place in this century shows that human failure and vulnerability of risk management programs are the main causes for the occurrence of accidents. As an example, plants and complex systems where the interface man-machine is close, the frequency of failures tends to be higher. Thus, a comprehensive knowledge of how a specific process can be potentially hazardous is a sine qua non condition to the operators training, as well as to define and implement more efficient plans for loss prevention and risk management. A study of the IEA-R1 research reactor start-up procedures was carried out, based upon the methodology Hazard and Operability Study (HazOp). The analytical and qualitative multidisciplinary HazOp approach provided means to a comprehensive review of the reactor start-up procedures, contributing to improve the understanding of the potential hazards associated to deviations on performing this routine. The present work includes a historical summary and a detailed description of the HazOp technique, as well as case studies in the process industries and the use of expert systems in the application of the method. An analysis of 53 activities of the IEA-R1 reactor start-up procedures was made, resulting in 25 recommendations of changes covering aspects of the project, operation and safety of the reactor. Eleven recommendations have been implemented. (author)

1988-01-01

This work presents spatial and energetic flux distribution measured in the IEA-R1 reactor core. The thermal neutron flux was measured by gold activation foils (bare and covered with cadmium) in the fuel element number 108 (reaction: 197 Au(n,γ) 198 Au) at 451W overall reactor power. The fast neutron flux was measured by indium activation foils (reaction: 115 In(n,n') 115m In) in the fuel elements number 94 at 4510W overall reactor power. The neutron energy spectrum was adjusted by SAND II code with the data produced by the irradiation of seven activation detectors in the fuel element number 94 at 4510 W overall reactor power. The following reactions were used: 58 Fe(n,γ) 59 Fe, 232 Th(n,γ) 233 Th, 197 Au(n,γ) 198 Au, 59 Co(n,γ) 60 Co, 54 Fe(n,p) 54 Mn, 24 Mg(n,p) 24 Na, 47 Ti(n,p) 47 Sc, 48 Ti(n,p) 48 Sc and 115 In(n,n') 115m In. The experimental results compared to those obtained by CITATION (spatial distribution flux) and HAMMER (energetic distribution flux) code, showed good agreement. The results presented in this work are a good contribution for a better knowledge of spatial and energetic neutron flux distribution in the IEA-R1 reactor core, besides that the experimental procedure is easily applicable to another situations.

A survey of self-powered neutron detectors, SPND, which are used as part of the in-core instrumentation of nuclear reactors is presented. Measurements with Co and Er SPND's were made in the IEA-R1 reactor for determining the neutron flux distribution and the integral reactor power. Due to the size of the available detectors, the neutron flux distribution could not be obtained with accuracy. The results obtained in the reactor power measurements demonstrate that the SPND have the linearity and the quick response necessary for a reactor power channel. This work also presents a proposed design of a SPND using Pt as wire emissor. This proposed design is based in the experience gained in building two prototypes. The greatest difficulties encountered include materials and technology to perform the delicate weldings. (author)

Ensuring energy security and addressing climate change cost-effectively are key global challenges. Tackling these issues will require efforts from stakeholders worldwide. To find solutions, the public and private sectors must work together, sharing burdens and resources, while at the same time multiplying results and outcomes. Through its broad range of multilateral technology initiatives (Implementing Agreements), the IEA enables member and non-member countries, businesses, industries, international organisations and non-governmental organisations to share research on breakthrough technologies, to fill existing research gaps, to build pilot plants and to carry out deployment or demonstration programmes across the energy sector. This publication highlights the most significant recent achievements of the IEA Implementing Agreements. At the core of the IEA energy technology network, these initiatives are a fundamental building block for facilitating the entry of new and improved energy technologies into the marketplace.

2009-07-01

Neutronic, thermal-hydraulics and accident analysis calculations were developed to estimate the safety of an irradiation device placed in the IEA-R1 reactor core. The irradiation device will be used to receive miniplates of U{sub 3}O{sub 8}-Al e U{sub 3}Si{sub 2}-Al dispersion fuels, LEU type (19.9% of {sup 235}U), with uranium densities of, respectively, 3.0 gU/cm{sup 3} and 4.8gU/cm{sup 3}. The fuel miniplates will be irradiated to nominal {sup 235}U burnup levels of 50% and 80%, in order to qualify the above high-density dispersion fuels to be used in the Brazilian Multipurpose Reactor, now in the conception phase. For the neutronic calculation, the computer code CITATION was utilized. The computer code FLOW was used to calculate the coolant flow rate in the irradiation device, allowing the determination of the fuel miniplate temperatures with the computer model MTRCR-IEA-R1. A postulated Loss of Coolant Accident (LOCA) was analyzed with the computer codes LOSS and TEMPLOCA, allowing the calculation of the fuel miniplate temperatures after the reactor pool draining. The calculations showed that the irradiation of the fuel miniplates will happen without any adverse consequence in the IEA-R1 reactor. (author)

Technology Roadmaps: How2Guide for Wind Energy Roadmap

Energy Technology Data Exchange (ETDEWEB)

2014-03-01

Whether in OECD, emerging or developing country economies, governments are increasingly looking to diversify their energy mix beyond simply fossil fuels. While wind energy is developing towards a mainstream, competitive and reliable technology, a range of barriers can delay progress, such as financing, grid integration, social acceptance and aspects of planning processes. National and regional technology roadmaps can play a key role in supporting wind energy development and implementation, helping countries to identify priorities and pathways tailored to local resources and markets. Recognising this, the IEA has started the How2Guides - a new series co-ordinated by the International Low-Carbon Energy Technology Platform to address the need for more focused guidance in the development of national roadmaps, or strategies, for specific low-carbon technologies. This builds on the success of the IEA global technology roadmap series and responds to a growing number of requests for IEA guidance to adapt the findings of the IEA global technology roadmaps to national circumstances. A successful roadmap contains a clear statement of the desired outcome, followed by a specific pathway for reaching it. The How2Guide for Wind Energy builds on the IEA well established methodology for roadmap development and shares wind specific recommendations on how to address the four phases to developing and implementing a wind energy roadmap: Planning; Visioning; Development; and Implementation. The manual also offers menus of recommendations on policy and technical options for deployment of utility-scale wind energy installations. A matrix of barriers-versus-realistic solutions options is cross-listed with considerations such as planning, development, electricity market and system, infrastructure, and finance and economics. Drawing on several case studies from around the globe, as well as on the IEA Technology Roadmap for Wind Energy, the How2Guide for Wind Energy it is intended as a

Radiation Emergency alert will be announced when the radiological impact is limited within the NPP or radiological impact to go out of the NPP. Radiation Protection Training is scheduled and proceeded to prevent for the radiation accidents, possibility of the radiation accidents, or radiation accident expansion, the training is to reduce the damage to property and health for the nuclear power plant worker and the people near the nuclear power plant. This paper shows the improvement of the nuclear radiation protection training for the simulator and on sharing method of the safety parameter with the emergency organization. Accident shall be correctly and quickly prevented when the NPP accident is inevitable. Therefore the radiation protection training for the operator and the emergency organization will be effective when the accident happens if the simulator has the same environment as the NPP.

This document has been produced to provide the definition and rationale for the Baseline Offshore Wind Farm established within IEA Wind Task 26--Cost of Wind Energy. The Baseline has been developed to provide a common starting point for country comparisons and sensitivity analysis on key offshore wind cost and value drivers. The baseline project reflects an approximate average of the characteristics of projects installed between 2012 and 2014, with the project life assumed to be 20 years. The baseline wind farm is located 40 kilometres (km) from construction and operations and maintenance (O&M) ports and from export cable landfall. The wind farm consists of 100 4-megawatt (MW) wind turbines mounted on monopile foundations in an average water depth of 25 metres (m), connected by 33-kilovolt (kV) inter-array cables. The arrays are connected to a single offshore substation (33kV/220kV) mounted on a jacket foundation, with the substation connected via a single 220kV export cable to an onshore substation, 10km from landfall. The wind farm employs a port-based O&M strategy using crew-transfer vessels.

Collaborate, compete and share

Pugliese, Emanuele; Castellano, Claudio; Marsili, Matteo; Pietronero, Luciano

2009-02-01

We introduce and study a model of an interacting population of agents who collaborate in groups which compete for limited resources. Groups are formed by random matching agents and their worth is determined by the sum of the efforts deployed by agents in group formation. Agents, on their side, have to share their effort between contributing to their group’s chances to outcompete other groups and resource sharing among partners, when the group is successful. A simple implementation of this strategic interaction gives rise to static and evolutionary properties with a very rich phenomenology. A robust emerging feature is the separation of the population between agents who invest mainly in the success of their group and agents who concentrate in getting the largest share of their group’s profits.

2009-01-01

As a computational fluid mechanics training task, a preliminary model was developed. ANSYS-CFX R code was used in order to study the flow at the inlet nozzle of the heat exchanger of the primary circuit of the nuclear research reactor IEA-R1. The geometry of the inlet nozzle is basically compounded by a cylinder and two radial rings which are welded on the shell. When doing so there is an offset between the holes through the shell and the inlet nozzle. Since it is not standardized by TEMA, the inlet nozzle was chosen for a preliminary study of the flow. Results for the proposed model are presented and discussed. (author)

Emerging Problems in Knowledge Sharing and the Three New Ethics of Knowledge Transfer

Directory of Open Access Journals (Sweden)

Mikhail Koulikov

2011-06-01

Full Text Available Topics related to knowledge management and knowledge sharing have received extensive attention in the recent literature of management and information science. Much of the discussion has focused on how these processes take place - and frequently fail to take place - in formal business, corporate and organizational settings. Knowledge sharing, however, occurs along the entire spectrum of human activity. Often, information and knowledge are shared in ways that appear unregulated and even outright subversive. This paper surveys many of the recent critiques of formal mechanisms of knowledge sharing. It identifies a set of methods, structures and ethics of "informal" and unauthorized transfer of information, and suggests that these can offer valuable lessons for the further development of the study of knowledge sharing methods, practices and behaviors in all types of settings.

International Environmental Agreements (IEAs) are a form of cooperation ratified by countries which can improve the management of shared environmental resources. The authors analyze the stability of International Environmental Agreements in leadership model. In 2006, Diamantoudi & Sartzetakis found that a stable coalition consists of either 2, 3, or 4 members if the number of countries is greater than 4. Their model is reconsidered. It is shown that the size of stable IEAs decreases from 3 to 2 when the total number of countries involved increases. However, a situation that can guarantee 4 to be the size of stable IEAs could not be found.

The concept of the annual load duration curve of the national interconnected system is presented, which by means of a quadrature procedure becomes a 3-block diagram: one for the base load that occurs at 8,760 hours of the year; another for intermediate load, above the minimum that occurs in a variable number of hours of the year, and another for the peak demand that only happens a few hours of the year. The data of the table of capacity and generation of electric power in 2014, according to Annex A of the Mexico Energy Outlook document of the International Energy Agency (Iea), are converted into a block diagram adjusted to the annual curve of load duration of that year. The procedure is repeated with the capacity and electric power generation data projected by the Iea at 2030 and 2040, according to the 450ppm scenario, which is considered necessary to stabilize the concentration of CO{sub 2} in the atmosphere at 450 parts per million and ensure that the increase in the global temperature of the planet does not exceed 2 degrees Celsius, compared to pre-industrial levels. Then, the same capacity and generation data projected by the Iea by 2040 are tabulated by technology type, grouped now within the base, intermediate and peak blocks of the annual load duration curve for that year, and ordered from according to its plant factor, indicative of its availability to be dispatched. The above, in order to estimate the aggregate result of the annual dispatch that could be made by CENACE, if the projections of electric power generation to the year 2040 foreseen in the ambitious 450ppm scenario were given. Finally, an exercise is carried out to estimate, at 2015 prices, the unit costs of technologies generation in the year 2040, expressed in US D (2015)/ MWh and broken down into fixed and variable reference costs.

Impact of uranium concentration reduction in side plates of the fuel elements of IEA-R1 reactor on neutronic and thermal hydraulic analyses

International Nuclear Information System (INIS)

Rios, Ilka Antonia

2013-01-01

This master thesis presents a study to verify the impact of the uranium concentration reduction in the side plates of the reactor IEA-R1 fuel elements on the neutronic and thermal-hydraulic analyses. To develop such study, a previous IPEN-CNEN/SP research was reproduced by simulating the fuel elements burn-up, with side plate uranium density reduced to 50, 60 and 70% of the standard fuel element plates. This research begins with the neutronic analysis using the computer code HAMMER and the first step consists in the calculation of the cross section of all materials presented at the reactor core, with their initial concentration; the second step consists in the calculation of the fast and thermal neutron group fluxes and power densities for fuel elements using the computer code CITATION. HAMMER output data is used as input data. Once the neutronic analysis is finished and the most critical fuel elements with highest power density have been defined, the thermal-hydraulics analysis begins. This analysis uses MCTR-IEA-R1 thermal-hydraulics model, which equations are solved by commercial code EES. Thermalhydraulics analysis input is the power density data calculated by CITATION: it is considered the highest power density on each fuel element, where there is a higher energy release and, consequently, higher temperatures. This data is used on energy balance equations to calculate temperatures on critical fuel element regions. Reactor operation comparison for three different uranium densities on fuel side plates is presented. Uranium density reduction contributes to the cladding surface temperature to remain below the established limit, as reactor operation safety requirement and it does not affect significantly fuel element final burn-up nor reactor reactivity. The reduction of uranium in the side plates of the fuel elements of the IEA-R1 showed to be a viable option to avoid corrosion problems due to high temperatures. (author)

Chile has experienced several serious energy supply incidents over the last decade, including major droughts, a sustained gas supply cut from Argentina (since 2004), and a major earthquake in early 2010 which affected electricity networks and refineries, and caused several black-outs. Due to Chile's unique and sinuous geography - it runs 4 300 kilometres from North to South and only 175 kms from East to West- the country's energy markets are regionally disjointed, particularly as the regional gas and electricity grids are not connected. In the arid North, energy demand is dominated by the mining industry, and operates based on a separate thermal-based Sistema Interconectado Norte Grande (SING) electricity grid. The more densely-populated central region (including Santiago) operates on the more hydro-dependent Sistema Interconectado Central (SIC) electricity grid. The southernmost, hydro-rich regions of the country are not connected to the rest of Chile in terms of electricity and gas. The following report is based on an IEA Emergency Response Assessment carried out in 2010 and 2011 which looked specifically at Chile's capacity to respond to short-term emergencies in oil, gas and electricity.

Tackling investment challenges in power generation - in IEA countries

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-07-01

In most IEA countries a new investment cycle in power generation is looming. A window of opportunity now exists to push for a cleaner and more efficient generation portfolio that could transform the power sector and help to build a more sustainable infrastructure lasting over the next 40-50 years. What are the recent trends and prospects for investment in power generation? What are the main drivers and barriers? This book assesses these issues and gives special emphasis to the question of how uncertainties may affect investment decisions. Uncertainties on CO{sub 2} constraints, on power plant licensing, on acceptability of nuclear power, on local opposition to any new energy infrastructure, on government support for specific generation technologies and on government policies on energy efficiency are particularly disturbing. Market liberalisation can also be a key uncertainty, but this may be greatly reduced and deliver considerable benefits if liberalisation is implemented whole-heartedly and backed by on-going government commitment. Government action is urgently needed: to reduce regulatory uncertainty for investors, to establish effective competitive markets and to give firm policy directions in those areas where markets fall short, such as in taking environmental costs and security of supply into account.

Larsen, H.; Soenderberg Petersen, L.

2002-10-01

All over the world, increasing energy consumption, liberalisation of energy markets and the need to take action on climate change are producing new challenges for the energy sector. At the same time there is increasing pressure for research, new technology and industrial products to be socially acceptable and to generate prosperity. The result is a complex and dynamic set of conditions affecting decisions on investment in research and new energy technology. To meet these challenges in the decades ahead, industrialists and policymakers need appropriate analyse energy systems, plus knowledge of trends for existing technologies and prospects for emerging technologies. This is the background for this first Risoe Energy Report, which sets out the global, European and Danish energy scene together with trends in development and emerging technologies. The report is the first in a new series from Risoe National Laboratory. The global energy developments are presented based on the latest available information from authoritative sources like IEA, WEC, World Energy Assessment etc. Some of the major challenges are presented in terms of the changing energy markets in all regions, the focus on environmental concerns in the industrialised countries, and energy for development and access to energy for the poor in developing countries. The report presents the status of R and D in progress for supply technologies. The various technologies are assessed with respect to status, trends and perspectives for the technology, and international R and D plans. For the technologies where Risoe is undertaking R and D this is highlighted in a separate section. Recent studies of emerging energy technologies from international organisations and leading research organisations are reviewed. There are reviews of national research activities on new energy technologies in a number of countries as well as in Risoe National Laboratory.

Sharing R&D investments in international environmental agreements with asymmetric countries

Science.gov (United States)

Biancardi, Marta; Villani, Giovanni

2018-05-01

This paper studies the coalition formation and the stability of the International Environmental Agreements (IEAs) in a pollution abatement dynamic model. We point out two meaningful aspects of this topic. Firstly, we consider asymmetry among countries, dividing them into two types: developed countries with a considerable environmental awareness and developing ones that pay less attention to environmental preservation. In addition, the former have a high-technology industry that allows for a unit abatement cost lower than the latter, and that are characterized by a labour-intensive industrial structure. Secondly, we introduce a positive externality in the cooperation by considering the R&D investment as two costs, namely the research investment and the developing cost. We assume that countries can coordinate their R&D activities by sharing their fixed research investments in order to avoid duplication of green activities. Moreover, by collaborating developing efforts, cooperators benefit from a reduction of a unit abatement cost higher than defectors. On the other hand, although non-cooperators completely support R&D investments for clean technologies, they realize lower abatements and benefits of a spillover effect due to development investments realized by cooperators. These two aspects could encourage the formation of stable coalitions.

Full Text Available This paper studies the impact of emergencies on the supplier’s decision-making behaviors including production and information sharing in consideration of consumer risk perception, consumer loss aversion phenomenon, and government price control. The intensity of emergencies is sequential and emergencies can be divided into two types (positive or negative according to their effect on demand. When emergencies have negative effect on demand, the supplier’s sales will reduce and he would share information to the market. When emergencies have positive effect on demand, we find that when the price is under price cap the supplier will not share information to the market; when the price reaches price cap, the supplier will share a certain amount of information to the market. We were surprised to find that increasing demand is not always good for the supplier when there exist government price control and lost sales penalty, and information helps the supplier to effectively manipulate demand.

2006-01-01

Created in 1977 and now in its Second Generation of Hydrogen R, D and D, the International Energy Agency (IEA) Hydrogen Implementing Agreement (HIA) is the oldest, largest international collaboration on hydrogen Research, Development and Demonstration (RD and D). As a global resource for technical expertise in hydrogen R, D and D, the HIA has expanded worldwide opportunities for hydrogen by undertaking 21 annexes (or tasks) on hydrogen production, storage, analysis of integrated systems and related topics with its 19 member countries. Related topics include hydrogen safety, conversion, economics and markets. The majority of the HIA's R and D portfolio has focused on longer term, pre-competitive R, D and D issues. Of the 21 annexes undertaken by the HIA, 15 are now complete. The HIA is also committed to outreach in support of both its core R and D activities and related issues such as regulation and infrastructure. As ever, the HIA welcomes collaboration and liaison with interested groups in the public and private sectors. (authors)

2012-07-01

This report is the Norwegian team contribution to Task A within the IEA Heat Pumps Programme Annex 34 on #Left Double Quotation Mark#Thermally driven heat pumps#Right Double Quotation Mark#. It aims to give an overview of the thermally driven heat pump (TDHP) and chiller (TDC) market, recent developments in the area of TDHP and TDC, as well as to give an outlook of the progress of this technology. There are no Norwegian manufacturers on the TDHP market. There are only seven existing thermally driven absorption system installations in Norway. Three are district heat driven water/LiBr chillers, one is a steam driven water/LiBr chiller, one water/LiBr heat pump for flue gas condensation in a wood chip heating unit, and two gas driven ammonia-water chillers. The future market for thermally driven heat pumps and chillers in Norway is expected to be in combination of biomass, district heat or waste heat. (Author)

Energy policies of IEA countries: Luxembourg -- 2008 Review

Energy Technology Data Exchange (ETDEWEB)

NONE

2009-03-20

Luxembourg has reformed its energy policies across all sectors since the last IEA in-depth review in 2004. The country has fully liberalised its electricity and natural gas markets, and is actively participating in the development of the evolving Central West European regional electricity system. Luxembourg has also prepared a broad action plan on energy efficiency, improved the support system for renewable energy sources and revised taxes to mitigate climate change. The country's energy policy in the coming decade will be shaped by the EU 2020 targets that call for substantial reductions in greenhouse gas emissions, and strong increases in renewable energy and energy efficiency. These targets will be hard to meet, given that roughly half of energy-related CO2 emissions come from transport fuel use by foreign truckers and motorists, and that Luxembourg's potential for producing much more renewable energy is limited. Luxembourg is heavily dependent on oil. Although oil sources are well diversified by country of origin, more than 85% of oil stocks are held in neighbouring countries and often based on short-term leasing contracts. This leaves the country vulnerable to potential oil supply disruptions. Luxembourg should swiftly implement a plan to improve the security of oil supply. This review analyses the energy challenges facing Luxembourg and provides critiques and recommendations for further policy improvements. It is intended to help guide the country towards achieving its sustainability targets.

Barriers to knowledge sharing in Chinese healthcare referral services: an emergent theoretical model

Science.gov (United States)

Nunes, Miguel Baptista

2016-01-01

Background This paper reports on a research study that aims to identify and explain barriers to knowledge sharing (KS) in the provision of healthcare referral services in Chinese healthcare organisations. Design An inductive case study approach was employed, in which 24 healthcare professionals and workers from four healthcare organisations in the province of Hubei, Central China, were interviewed using semi-structured scripts. Results Through data analysis, 14 KS barriers emerged in four main themes: interpersonal trust barriers, communication barriers, management and leadership barriers, and inter-institutional barriers. A cause–consequence analysis of the identified barriers revealed that three of them are at the core of the majority of problems, namely, the absence of national and local policies for inter-hospital KS, lack of a specific hospital KS requirement, and lack of mutual acquaintance. Conclusions To resolve KS problems, it is of great importance that healthcare governance agencies, both at the national and regional levels, take leadership in the process of KS implementation by establishing specific and strong policies for inter-institutional KS in the referral process. This paper raises important issues that exceed academic interests and are important to healthcare professionals, hospital managers, and Information communication technology (ICT) managers in hospitals, as well as healthcare politicians and policy makers.

Boyle, Adrian A; Snelling, Katrina; White, Laura; Ariel, Barak; Ashelford, Lawrence

2013-12-01

Community violence is a substantial problem for the NHS. Information sharing of emergency department data with community safety partnerships (CSP) has been associated with substantial reductions in assault attendances in emergency departments supported by academic institutions. We sought to validate these findings in a setting not supported by a public health or academic structure. We instituted anonymous data sharing with the police to reduce community violence, and increased involvement with the local CSP. We measured the effectiveness of this approach with routinely collected data at the emergency department and the police. We used police data from 2009, and emergency department data from 2000. Initially, the number of assault patients requiring emergency department treatment rose after we initiated data sharing. After improving the data flows, the number of assault patients fell back to the predata-sharing level. There was no change in the number of hospital admissions during the study period. There were decreases in the numbers of violent crimes against the person, with and without injury, recorded by the police. We have successfully implemented data sharing in our institution without the support of an academic institution. This has been associated with reductions in violent crime, but it is not clear whether this association is causal.

Shared Mind: Communication, Decision Making, and Autonomy in Serious Illness

Science.gov (United States)

Epstein, Ronald M.; Street, Richard L.

2011-01-01

In the context of serious illness, individuals usually rely on others to help them think and feel their way through difficult decisions. To help us to understand why, when, and how individuals involve trusted others in sharing information, deliberation, and decision making, we offer the concept of shared mind—ways in which new ideas and perspectives can emerge through the sharing of thoughts, feelings, perceptions, meanings, and intentions among 2 or more people. We consider how shared mind manifests in relationships and organizations in general, building on studies of collaborative cognition, attunement, and sensemaking. Then, we explore how shared mind might be promoted through communication, when appropriate, and the implications of shared mind for decision making and patient autonomy. Next, we consider a continuum of patient-centered approaches to patient-clinician interactions. At one end of the continuum, an interactional approach promotes knowing the patient as a person, tailoring information, constructing preferences, achieving consensus, and promoting relational autonomy. At the other end, a transactional approach focuses on knowledge about the patient, information-as-commodity, negotiation, consent, and individual autonomy. Finally, we propose that autonomy and decision making should consider not only the individual perspectives of patients, their families, and members of the health care team, but also the perspectives that emerge from the interactions among them. By drawing attention to shared mind, clinicians can observe in what ways they can promote it through bidirectional sharing of information and engaging in shared deliberation. PMID:21911765

Policy Pathways: Modernising Building Energy Codes

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-08-01

Buildings are the largest consumers of energy worldwide and will continue to be a source of increasing energy demand in the future. Globally, the sector’s final energy consumption doubled between 1971 and 2010 to reach 2 794 million tonnes of oil equivalent (Mtoe), driven primarily by population increase and economic growth. Under current policies, the global energy demand of buildings is projected by the IEA experts to grow by an additional 838 Mtoe by 2035 compared to 2010. The challenges of the projected increase of energy consumption due to the built environment vary by country. In IEA member countries, much of the future buildings stock is already in place, and so the main challenge is to renovate existing buildings stock. In non-IEA countries, more than half of the buildings stock needed by 2050 has yet to be built. The IEA and the UNDP partnered to analyse current practices in the design and implementation of building energy codes. The aim is to consolidate existing efforts and to encourage more attention to the role of the built environment in a low-carbon and climate-resilient world. This joint IEA-UNDP Policy Pathway aims to share lessons learned between IEA member countries and non-IEA countries. The objective is to spread best practices, limit pressures on global energy supply, improve energy security, and contribute to environmental sustainability. Part of the IEA Policy Pathway series, Modernising building energy codes to secure our global energy future sets out key steps in planning, implementation, monitoring and evaluation. The Policy Pathway series aims to help policy makers implement the IEA 25 Energy Efficiency Policy Recommendations endorsed by IEA Ministers (2011).

Technology status of hydrogen road vehicles. IEA technical report from the IEA Agreement of the production and utilization of hydrogen

Energy Technology Data Exchange (ETDEWEB)

Doyle, T.A.

1998-01-31

The report was commissioned under the Hydrogen Implementing Agreement of the International Energy Agency (IEA) and examines the state of the art in the evolving field of hydrogen-fueled vehicles for road transport. The first phase surveys and analyzes developments since 1989, when a comprehensive review was last published. The report emphasizes the following: problems, especially backfiring, with internal combustion engines (ICEs); operational safety; hydrogen handling and on-board storage; and ongoing demonstration projects. Hydrogen vehicles are receiving much attention, especially at the research and development level. However, there has been a steady move during the past 5 years toward integral demonstrations of operable vehicles intended for public roads. Because they emit few, or no greenhouse gases, hydrogen vehicles are beginning to be taken seriously as a promising solution to the problems of urban air quality. Since the time the first draft of the report was prepared (mid-19 96), the 11th World Hydrogen Energy Conference took place in Stuttgart, Germany. This biennial conference can be regarded as a valid updating of the state of the art; therefore, the 1996 results are included in the current version. Sections of the report include: hydrogen production and distribution to urban users; on-board storage and refilling; vehicle power units and drives, and four appendices titled: 'Safety questions of hydrogen storage and use in vehicles', 'Performance of hydrogen fuel in internal production engines for road vehicles, 'Fuel cells for hydrogen vehicles', and 'Summaries of papers on hydrogen vehicles'.

Characterization of filters cartridges from the water polishing system of IEA-R1 reactor: radiometric methods

International Nuclear Information System (INIS)

Tessaro, Ana Paula G.; Vicente, Roberto

2015-01-01

The acceptance of radioactive waste in a repository depends primarily on knowledge of the radioisotopic inventory of the material, according to regulations established by regulatory agencies. The primary characterization is also a fundamental action to determine further steps in the management of the radioactive wastes. The aim of this work is to report the development of non-destructive methods for primary characterization of filters cartridges discarded as radioactive waste. The filters cartridges are used in the water polishing system of the IEA-R1 reactor retaining the particles in suspension in the reactor cooling water. The IEA-R1 is a pool type reactor with a thermal power of 5 MW, moderated and cooled with light water. It is located in the Energy and Nuclear Research Institute (IPEN-CNEN), in São Paulo, Brazil. The cartridge filters become radioactive waste when they are saturated and do not meet the required flow for the proper operation of the water polishing system. The activities of gamma emitters present in the filters are determined using gamma spectrometry, dose rate measurements and the Point Kernel Method to correlate results from both measurements. For the primary characterization, one alternative method is the radiochemical analysis of slices taken from each filter, what presents the disadvantage of higher exposures personnel and contamination risks. Another alternative method is the calibration of the measurement geometry of a gamma spectrometer, which requires the production of a standard filter. Both methods are necessary but can not be used in operational routine of radioactive waste management owing to cost and complexity. The method described can be used to determine routinely the radioactive inventory of these filters and other radioactive wastes, avoiding the necessity of destructive radiochemical analysis, or the necessity of calibrating the geometry of measurement.

Heat storage is essential for the reconciliation of heat supply and demand. The earth has already proved to be an excellent medium for storing large amounts of heat over longer periods of time, for instance during the cold and hot season. The efficiency of the storage is the better the lower storage losses are at high temperature levels. Unfortunately this can not be easily achieved. While thermal underground stores, which are widely used for cold storage, have proved to perform quite well at temperatures between 10 C - 40 C, it has been rather difficult to achieve similar results at higher temperatures up to 150 C as test and demonstration plants of the 1980s proved. This issue has again attracted so much interest that the IEA launched a project on high temperature underground storage in December 1998. (orig.) [Deutsch] Waermespeicherung ist von entscheidender Bedeutung, wenn es darum geht, ein Waermeangebot mit einer Waermenachfrage zeitlich zur Deckung zu bringen. Der Untergrund hat sich schon seit vielen Jahren als ein geeignetes Medium erwiesen, groessere Waermepumpen ueber laengere Zeitraeume wie etwa die kalten und warmen Jahreszeiten zu speichern. Die Effizienz eines solchen Speichers steigt mit der Hoehe des erreichten Temperaturniveaus und mit sinkenden Speicherverlusten, was leider eher gegenlaeufige Erscheinungen sind. Waehrend thermische Untergrundspeicher im Temperaturbereich von 10-40 C inzwischen erfolgreich demonstriert wurden und vor allem zur Kaeltespeicherung auch bereits vielfach eingesetzt werden, haben hoehere Temperaturen bis etwa 150 C in den Versuchs- und Demonstrationsanlagen der 80er Jahre vielfaeltige Probleme bereitet. Im Gefolge eines erneuten Interesses an unterirdischer thermischer Energiespeicherung wurde im Dezember 1997 ein Vorhaben des IEA Energiespeicherprogramms zu Untergrund-Waermespeichern hoeherer Temperatur eingerichtet.

Development of methodology for characterization of cartridge filters from the IEA-R1 using the Monte Carlo method; Desenvolvimento de uma metodologia para caracterizacao do filtro cuno do reator IEA-R1 utilizando o Metodo Monte Carlo

The Cuno filter is part of the water processing circuit of the IEA-R1 reactor and, when saturated, it is replaced and becomes a radioactive waste, which must be managed. In this work, the primary characterization of the Cuno filter of the IEA-R1 nuclear reactor at IPEN was carried out using gamma spectrometry associated with the Monte Carlo method. The gamma spectrometry was performed using a hyperpure germanium detector (HPGe). The germanium crystal represents the detection active volume of the HPGe detector, which has a region called dead layer or inactive layer. It has been reported in the literature a difference between the theoretical and experimental values when obtaining the efficiency curve of these detectors. In this study we used the MCNP-4C code to obtain the detector calibration efficiency for the geometry of the Cuno filter, and the influence of the dead layer and the effect of sum in cascade at the HPGe detector were studied. The correction of the dead layer values were made by varying the thickness and the radius of the germanium crystal. The detector has 75.83 cm{sup 3} of active volume of detection, according to information provided by the manufacturer. Nevertheless, the results showed that the actual value of active volume is less than the one specified, where the dead layer represents 16% of the total volume of the crystal. A Cuno filter analysis by gamma spectrometry has enabled identifying energy peaks. Using these peaks, three radionuclides were identified in the filter: {sup 108m}Ag, {sup 110m}Ag and {sup 60}Co. From the calibration efficiency obtained by the Monte Carlo method, the value of activity estimated for these radionuclides is in the order of MBq. (author)

IEA Bioenergy task 40. Country report for the Netherlands

International Nuclear Information System (INIS)

Junginger, M.; Faaij, A.

2005-07-01

Two of the short-term objectives of the IEA Bioenergy Task 40 are to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands, and also sets the first step to make an inventory of barriers as perceived by various Dutch stakeholders. The report organizes as follows. Section 2 and 3 presents a brief overview of the policy setting on renewable energy and bio-energy in the Netherlands and the policy instruments deployed to stimulate renewable energy market penetration. In section 4, the achievements, the current status and the short-term expectations for the use of biomass energy in the Netherlands are described. Next, in section 5, the biomass market and biomass trade in the Netherlands are discussed, including the major biomass streams involved, conversion technologies, import and export volumes, biomass prices, barriers for further import and biomass certification efforts. Section 6 concludes with a general discussion and conclusions.

Whole mind and shared mind in clinical decision-making.

Science.gov (United States)

Epstein, Ronald Mark

2013-02-01

To review the theory, research evidence and ethical implications regarding "whole mind" and "shared mind" in clinical practice in the context of chronic and serious illnesses. Selective critical review of the intersection of classical and naturalistic decision-making theories, cognitive neuroscience, communication research and ethics as they apply to decision-making and autonomy. Decision-making involves analytic thinking as well as affect and intuition ("whole mind") and sharing cognitive and affective schemas of two or more individuals ("shared mind"). Social relationships can help processing of complex information that otherwise would overwhelm individuals' cognitive capacities. Medical decision-making research, teaching and practice should consider both analytic and non-analytic cognitive processes. Further, research should consider that decisions emerge not only from the individual perspectives of patients, their families and clinicians, but also the perspectives that emerge from the interactions among them. Social interactions have the potential to enhance individual autonomy, as well as to promote relational autonomy based on shared frames of reference. Shared mind has the potential to result in wiser decisions, greater autonomy and self-determination; yet, clinicians and patients should be vigilant for the potential of hierarchical relationships to foster coercion or silencing of the patient's voice.

A three-dimensional distribution of the neutron flux in IEA-R1 reactor, obtained by activating gold foils, is presented. The foils of diameter 8mm and thickness 0,013mm were mounted on lucite plates and located between the fuel element plates. Foil activities were measured using a 3x3 inches Nal(Tl) scintilation detector calibrated against a 4πβγ coincidence detector. Foil positions were chosen to minimize the errors of measurement; the overall estimated error on the measured flux is 5%. (Author) [pt

The dispatch and load duration curve of the interconnected electrical system, in the hypothetical context of the 450ppm scenario of the Iea

International Nuclear Information System (INIS)

Villanueva M, C.

2017-09-01

The concept of the annual load duration curve of the national interconnected system is presented, which by means of a quadrature procedure becomes a 3-block diagram: one for the base load that occurs at 8,760 hours of the year; another for intermediate load, above the minimum that occurs in a variable number of hours of the year, and another for the peak demand that only happens a few hours of the year. The data of the table of capacity and generation of electric power in 2014, according to Annex A of the Mexico Energy Outlook document of the International Energy Agency (Iea), are converted into a block diagram adjusted to the annual curve of load duration of that year. The procedure is repeated with the capacity and electric power generation data projected by the Iea at 2030 and 2040, according to the 450ppm scenario, which is considered necessary to stabilize the concentration of CO 2 in the atmosphere at 450 parts per million and ensure that the increase in the global temperature of the planet does not exceed 2 degrees Celsius, compared to pre-industrial levels. Then, the same capacity and generation data projected by the Iea by 2040 are tabulated by technology type, grouped now within the base, intermediate and peak blocks of the annual load duration curve for that year, and ordered from according to its plant factor, indicative of its availability to be dispatched. The above, in order to estimate the aggregate result of the annual dispatch that could be made by CENACE, if the projections of electric power generation to the year 2040 foreseen in the ambitious 450ppm scenario were given. Finally, an exercise is carried out to estimate, at 2015 prices, the unit costs of technologies generation in the year 2040, expressed in US D (2015)/ MWh and broken down into fixed and variable reference costs.

Highly localized neuronal spikes in primate temporal cortex can encode associative memory; however, whether memory formation involves area-wide reorganization of ensemble activity, which often accompanies rhythmicity, or just local microcircuit-level plasticity, remains elusive. Using high-density electrocorticography, we capture local-field potentials spanning the monkey temporal lobes, and show that the visual pair-association (PA) memory is encoded in spatial patterns of theta activity in areas TE, 36, and, partially, in the parahippocampal cortex, but not in the entorhinal cortex. The theta patterns elicited by learned paired associates are distinct between pairs, but similar within pairs. This pattern similarity, emerging through novel PA learning, allows a machine-learning decoder trained on theta patterns elicited by a particular visual item to correctly predict the identity of those elicited by its paired associate. Our results suggest that the formation and sharing of widespread cortical theta patterns via learning-induced reorganization are involved in the mechanisms of associative memory representation.

Doping of monocrystalline silicon with phosphorus by means of neutron irradiation at the IEA-R1 research reactor

Carbonari, A.W.; Puget, M.A.C.

1990-11-01

The first neutron irradiation experiments with monocrystal silicon in the IEA-R1 research reactor of IPEN are related. The silicon is irradiated with phosphorus producing a N type semiconductor with a very small resistivity variation throughout the crystal volume. The neutrons induce nuclear reactions in Si-30 isotope and these atoms are then transformed in to phosphorous atoms. This process is known as Neutron Transmutation Doping. In order to irradiate the silicon crystals in the reactor, a specific device has been constructed, and it permits the irradiation of up to 2.5'' diameter monocrystals. (author)

Greenhouse gas emissions need to decrease substantially to limit global average temperature to a maximum of 2 C warming above the preindustrial level in 2100. Emerging economies are of increasing importance in this global effort. In this report we assess how ambitious emission reduction pledges of emerging economies are compared to business as usual emissions, the countries' mitigation potential and respective efforts based on different equity principles. We also compare the pledges and the identified mitigation potential of emerging economies to a global emissions pathway needed to limit global temperature increase to 2 C. Our assessment includes Brazil, China, India, Mexico, South Africa and South Korea. We find that emerging economies have a substantial impact on future global emission levels. This is due to high current levels and high projected growth rates. Also, in most of the countries a large emission reduction potential is available. Action needs to be taken soon to enable the full use of the potential until 2020 and most emerging economies will need significant support from developed countries to implement those.

Use of error-detection and diagnosis methods in existing buildings - Final report; Einsatz von Fehlerdetektions- und Diagnosemethoden in realen Gebaeuden (IEA Annex 34) - Schlussbericht

Energy Technology Data Exchange (ETDEWEB)

Gruber, P.

2000-10-15

This report for the Swiss Federal Office of Energy (SFOE) discusses the results of tests made with two expert systems used for error-detection and diagnosis in existing buildings. These expert systems were developed within the framework of the International Energy Agency's (IEA) Annex 25 Project entitled 'Real Time Simulation of Heating, Ventilation and Air-conditioning (HVAC) Systems for Building Optimisation, Fault Detection and Diagnosis'. The aim of using these tools was to help detect planning, installation and commissioning errors. These cannot only affect system performance but also can cause increased energy consumption and a reduction of the working life of the system's components. The tests of the tools took place within the framework of the IEA's Annex 34 'Computer-aided Evaluation of HVAC System Performance: the Practical Application of Fault Detection and Diagnosis Techniques in Real Buildings'. Experience gained with the two tools is presented and discussed. The quality of the results and the use of the systems in practice are discussed and commented on. They strongly differ from one tool to the other.

Menezes, M.O. de; Pugliesi, R.; Pereira, M.A.S.; Andrade, M.L.G.

2003-01-01

A LIXI (Light Intensifier X-ray Image) device has been employed in a real-time neutron radiography system. The LIXI is coupled to a video camera and the real-time images can be observed in a TV monitor, and processed in a computer. In order to get the real-time system operational, the neutron radiography facility installed at the IEA-R1 m nuclear research reactor of the IPEN-CNEN/S P has been optimized. The most important improvements were the neutron/gamma ratio, the effective energy of the neutron beam, decrease of the scattered radiation at the irradiation position, and the additional shielding of the video camera. Several one-frame as well as computer processed images are presented. The overall Modulation Transfer Function for the real-time system was obtained from the resolution parameter p = 0:44 +- 0:04 mm; the system sensitivity, evaluated for a Perspex step wedge, was determined and the average value is 0:70 +- 0:09 mm.

Created in 1977 and now in its Second Generation of Hydrogen R, D and D, the International Energy Agency (IEA) Hydrogen Implementing Agreement (HIA) is the oldest, largest international collaboration on hydrogen Research, Development and Demonstration (RD and D). As a global resource for technical expertise in hydrogen R, D and D, the HIA has expanded worldwide opportunities for hydrogen by undertaking 21 annexes (or tasks) on hydrogen production, storage, analysis of integrated systems and related topics with its 19 member countries. Related topics include hydrogen safety, conversion, economics and markets. The majority of the HIA's R and D portfolio has focused on longer term, pre-competitive R, D and D issues. Of the 21 annexes undertaken by the HIA, 15 are now complete. The HIA is also committed to outreach in support of both its core R and D activities and related issues such as regulation and infrastructure. As ever, the HIA welcomes collaboration and liaison with interested groups in the public and private sectors. (authors)

Within the framework of IEA SHC Task 42 / ECES Annex 29, a simple tool for the economic evaluation of thermal energy storages has been developed and tested on various existing storages. On that account, the storage capacity costs (costs per installed storage capacity) of thermal energy storages...... have been evaluated via a Top-down and a Bottom-up approach. The Top-down approach follows the assumption that the costs of energy supplied by the storage should not exceed the costs of energy from the market. The maximum acceptable storage capacity costs depend on the interest rate assigned...

Radical uncertainty, non-predictability, antifragility and risk-sharing Islamic finance

Directory of Open Access Journals (Sweden)

Full Text Available Under conditions of radical uncertainty, risk sharing renders financial systems anti-fragile. Our goal in this paper is to show that risk-sharing Islamic finance (RSIF shares the characteristics defined by Taleb for an anti-fragile system, by mapping some characteristics of anti-fragility onto those of risk-sharing Islamic finance. A key insight around which such a connection can be established is by relating the principle of “no risk-no gain”from Islamic finance to the concept of skin-in-the-game from anti-fragility theory. The relationship is then extended to other characteristics of the two frameworks, to show that RSIF overlaps with anti-fragility over many dimensions. The broader case for an antifragile system includes another important characteristic, namely “soul in the game” and concern for social justice. It is the authors’ hope that emerging research on anti-fragility, combined with the emerging research on RSIF, can have a lasting impact on the field of finance by laying the foundations for a compelling case that it is time for humanity to replace the dominant debt-based risk transfer/risk shifting financial system with a system in which everyone shares the risks faced by society.

Justify of implementation of a hot water layer system in swimming pool research reactor IEA-R1m

International Nuclear Information System (INIS)

Toyoda, Eduardo Yoshio; Gordon, Ana Maria Pinho Leite; Sordi, Gian-Maria A.A.

2001-01-01

The IPEN/CNEN-SP has a swimming pool research reactor (IEA-R1m) in operation since 1957 at 2 MW. In 1998, after some modifications, its nominal power increased to 5 MW. Among these modifications some adaptations had to be accomplished in the radiological protection and operational procedure. The present work aim to study the need of implementation of a hot water layer in order to reduce the dose in the workers in the vicinity of the reactor swimming pool. Applying the principles of radioprotection optimization, it was concluded that the decision of the construction of one hot water layer system in the reactor swimming pool, is not necessary. (author)

Online file sharing innovations in media consumption

It is apparent that file sharing on the Internet has become an emerging norm of media consumption-especially among young people. This book provides a critical perspective on this phenomenon, exploring issues related to file sharing, downloading, peer-to-peer networks, ""piracy,"" and (not least) policy issues regarding these practices. Andersson Schwartz critically engages with the justificatory discourses of the actual file-sharers, taking Sweden as a geographic focus. By focusing on the example of Sweden-home to both The Pirate Bay and Spotify-he provides a unique insight into a mentality th

Modernization of Safety and Control Instrumentation of the IEA-R1 Research Reactor

The research reactor IEA-R1 located in the Institute of Energy and Nuclear Research (IPEN), São Paulo, Brazil, obtained its first criticality on 16 September 1957 and since then has served the scientific and medical community in the performance of experiments in applied nuclear physics, as well as the provision of radioisotopes for production of radiopharmaceuticals. The reactor produces radioisotopes {sup 82}Br and {sup 41}Ar for special processes in industrial inspection and {sup 192}Ir and {sup 198}Au as sources of radiation used in brachytherapy, {sup 153}Sm for pain relief in patients with bone metastasis, and calibrated sources of {sup 133}Ba, {sup 137}Cs, {sup 57}Co, {sup 60}Co, {sup 241}Am and {sup 152}Eu used in medical clinics and hospitals practicing nuclear medicine and research laboratories. Services are offered in regular non-destructive testing by neutron radiography, neutron irradiation of silicon for phosphorous doping and other various irradiations with neutrons. The reactor is responsible for producing approximately 70% of radiopharmaceutical {sup 131}I used in Brazil, which saves about US$ 800 000 annually for the country. After more than 50 years of use, most of its equipment and systems have been modernized, and recently the reactor power was increased to 5 MW in order to enhance radioisotope production capability. However, the control room and nuclear instrumentation system used for reactor safety have operated more than 30 years and require constant maintenance. Many equipment and electronic components are obsolete, and replacements are not available in the market. The modernization of the nuclear safety and control instrumentation systems of IEA-R1 is being carried out with consideration for the internationally recognized criteria for safety and reliable reactor operations and the latest developments in nuclear electronic technology. The project for the new reactor instrumentation system specifies three wide range neutron monitoring

Knowledge Sharing Strategies for Large Complex Building Projects.

Directory of Open Access Journals (Sweden)

Esra Bektas

knowledge sharing. In the literature, two main approaches on knowledge sharing can be distinguished, an object or content -oriented perspective and a community-oriented perspective. In the object perspective, technology is seen as a medium to store and share knowledge. The limitations of this perspective are that social processes and tacit knowledge are not adequately supported and there has generally been a slow adoption of such technology in design practices. The community perspective prevents these problems by allowing for the natural and informal formation of communities, however, communities can become largely independent and unconnected, which makes it more difficult to entice them towards a certain strategic direction. Since both approaches have their limitations, this thesis proposes a holistic framework for knowledge sharing in LCBPs drawing on concepts by Mintzberg (1973 and Activity Theory. Mintzberg’s concepts are used to discuss the type of implementation (top-down, bottom-up, and the origin of the strategies (deliberate/emergent/(unrealized. For analysing the content and effect of each strategy, concepts from Activity Theory (tools, subject, object, rules, community, and division of labour are used. The proposed model, the Knowledge Diamond, consists of four dimensions for analysing and designing knowledge sharing strategies for LCBPs. Three of these were inspired by Activity Theory, namely tools, procedures, and social practices, while a fourth emerged as a crucial dimension in this thesis: physical settings. This framework was used to examine knowledge sharing strategies in a comparative analysis of two large complex building projects. Based on rich data from observations, documents and interview, the origins, the development and the effect of both forms of knowledge sharing environments are investigated. The first part of the analysis sheds new light on the possibilities of knowledge sharing in large complex building project. The unique, temporary, and

Abstract: Recent peace negotiations practice has given rise to the emergence of two paradigms. In line with normative developments in global human rights protection, internationally brokered peace processes often address the options for accountability for abuses committed in the past and generally cannot include blanket amnesties. At the same time, many agreements end armed conflicts by offering power-sharing incentives for warring parties. In most cases, power-sharing arrangements are likely...

Energy policies of IEA countries: Finland - 2007 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-03-15

Faced with considerable challenges related to its geography and size, Finland's sound energy policies do much to overcome its situation. The country leverages its small market where it can - such as by adopting or harmonising with EU directives and policies. To counter its relative isolation, Finland strengthened its position by becoming part of the larger Nordic electricity market and enhancing energy linkages. At the core, however, the country ensures energy security by relying on transparency and sound market signals to investors and customers, as well as by making good use of domestic sources of biomass and nuclear. As Finland continues to refine and enhance its energy policy, there are some areas that warrant special attention. As nearly all fossil fuels are imported and all natural gas comes through a single interconnection, the government should continue to explore ways to diversify import sources and routes. The new nuclear power plant currently being built - the first in a liberalised market - will help safeguard energy security, though the construction delays necessitate continued monitoring. Subsidies for peat, a fuel in abundance in Finland, should be reconsidered, as they do not enhance energy security. On the other hand, the government should continue to explore ways to expand new renewables, building on the current stock of biomass and hydro. This book takes an in-depth look at Finland's energy policy today and, through comparisons with good examples in other IEA countries, provides critiques and recommendations for improvements to guide the country towards a sustainable energy future. While the review provides comprehensive coverage of all topics, this thematic report highlights energy efficiency and energy R and D.

Using the IEA ETSAP modelling tools for Denmark

Energy Technology Data Exchange (ETDEWEB)

Grohnheit, Poul Erik

2008-12-15

An important part of the cooperation within the IEA (International Energy Agency) is organised through national contributions to 'Implementation Agreements' on energy technology and energy analyses. One of them is ETSAP (Energy Technology Systems Analysis Programme), started in 1976. Denmark has signed the agreement and contributed to some early annexes. This project is motivated by an invitation to participate in ETSAP Annex X, 'Global Energy Systems and Common Analyses: Climate friendly, Secure and Productive Energy Systems' for the period 2005 to 2007. The main activity is semi-annual workshops focusing on presentations of model analyses and use of the ETSAP tools (the MARKAL/TIMES family of models). The project was also planned to benefit from the EU project 'NEEDS - New Energy Externalities Developments for Sustainability'. ETSAP is contributing to a part of NEEDS that develops the TIMES model for 29 European countries with assessment of future technologies. An additional project 'Monitoring and Evaluation of the RES directives: implementation in EU27 and policy recommendations for 2020' (RES2020) under Intelligent Energy Europe was added, as well as the Danish 'Centre for Energy, Environment and Health (CEEH), starting from January 2007. This report summarises the activities under ETSAP Annex X and related project, emphasising the development of modelling tools that will be useful for modelling the Danish energy system. It is also a status report for the development of a model for Denmark, focusing on the tools and features that allow comparison with other countries and, particularly, to evaluate assumptions and results in international models covering Denmark.

2005-07-01

This report provides a comprehensive in-depth assessment of the energy policies of Turkey including recommendations by the IEA on future policy developments. Recently, Turkey has taken steps to implement energy market reforms which have resulted in clear and significant benefits. Now, continued action is needed to see the process through to a successful conclusion. It is necessary to restructure the state-owned enterprises to operate in a competitive market, to create independent electricity and gas operators and to remove cross-subsidies from electricity and gas prices. Turkey has been very active in international co-operation in the energy sector. Some important oil and gas pipeline projects are underway or almost completed. This will improve the security of supply in Turkey and maintain its role as an important 'energy corridor' between East and West, while avoiding overuse of the Turkish Straits. Synchronisation of Turkey's electricity networks with the European UCTE grid is planned for 2006. Furthermore, the country already has transposed most EU energy laws and standards into national legislation. Turkey's general approach to energy policy has been highly supply-oriented. However, recent efforts have begun to focus more on energy efficiency and conservation. Nevertheless, stronger energy efficiency policies are needed, particularly in the transport sector. Turkey ratified the Framework Convention on Climate Change in February 2004 and is developing its climate change strategy. The government should strive to monitor the cost-effectiveness of its policies, consider defining an emissions target and ensure coordination among the various government bodies. Despite past progress, work remains to be done to achieve further reductions in air pollution. 28 figs., 23 tabs., 3 annexes

World energy outlook: how to share the efforts to be achieved by 2030?

International Nuclear Information System (INIS)

2008-01-01

This conference was organized a month after the publication by the International Energy Agency (IEA) of the 2007 World Energy Outlook (WEO) study. The energy situation at that time was marked by the repercussions on the environment and on the security of supplies in relation with the accelerated development of China and India. This document gathers the transparencies of the two presentations given at this conference. The first presentation by Fatih Birol, Chief Economist at the IEA, is entitled 'World Energy Outlook 2007: China and India Insights'. It presents the Cooperation with China's National Development and Reform Commission (NDRC) and Energy Research Institute (ERI), and with India's Energy and Resources Institute (TERI) for the establishment of energy scenarios. Then the different scenarios are reviewed: Reference Scenario, Alternative Policy Scenario and 450 Stabilisation Case, High Growth Scenario (China/India). Finally, a full global update of projections (all scenarios) is presented and the impact of China and India on global economy, energy markets and environment is analyzed. The conclusions are as follows: - Global energy system is on an increasingly unsustainable path; - China and India are transforming the global energy system by their sheer size; - Challenge for all countries is to achieve transition to a more secure, lower carbon energy system; - New policies now under consideration would make a major contribution; - Next 10 years are critical (The pace of capacity additions will be most rapid, Technology will be 'locked-in' for decades, Growing tightness in oil and gas markets); - Challenge is global so solutions must be global. The second presentation by Jean-Charles Hourcade (CIRED) is entitled 'The WEO 2007 A few comments about the Emerging Giants... and us'. The presentation focusses on 4 points: - What implications of higher growth in the Asian Giants on the world economy through higher pressure on energy resources; - Economic questions

A meta-analysis of shared leadership and team effectiveness.

Wang, Danni; Waldman, David A; Zhang, Zhen

2014-03-01

A growing number of studies have examined the "sharedness" of leadership processes in teams (i.e., shared leadership, collective leadership, and distributed leadership). We meta-analytically cumulated 42 independent samples of shared leadership and examined its relationship to team effectiveness. Our findings reveal an overall positive relationship (ρ = .34). But perhaps more important, what is actually shared among members appears to matter with regard to team effectiveness. That is, shared traditional forms of leadership (e.g., initiating structure and consideration) show a lower relationship (ρ = .18) than either shared new-genre leadership (e.g., charismatic and transformational leadership; ρ = .34) or cumulative, overall shared leadership (ρ = .35). In addition, shared leadership tends to be more strongly related to team attitudinal outcomes and behavioral processes and emergent team states, compared with team performance. Moreover, the effects of shared leadership are stronger when the work of team members is more complex. Our findings further suggest that the referent used in measuring shared leadership does not influence its relationship with team effectiveness and that compared with vertical leadership, shared leadership shows unique effects in relation to team performance. In total, our study not only cumulates extant research on shared leadership but also provides directions for future research to move forward in the study of plural forms of leadership.

Development of methodology for characterization of cartridge filters from the IEA-R1 using the Monte Carlo method

International Nuclear Information System (INIS)

Costa, Priscila

2014-01-01

The Cuno filter is part of the water processing circuit of the IEA-R1 reactor and, when saturated, it is replaced and becomes a radioactive waste, which must be managed. In this work, the primary characterization of the Cuno filter of the IEA-R1 nuclear reactor at IPEN was carried out using gamma spectrometry associated with the Monte Carlo method. The gamma spectrometry was performed using a hyperpure germanium detector (HPGe). The germanium crystal represents the detection active volume of the HPGe detector, which has a region called dead layer or inactive layer. It has been reported in the literature a difference between the theoretical and experimental values when obtaining the efficiency curve of these detectors. In this study we used the MCNP-4C code to obtain the detector calibration efficiency for the geometry of the Cuno filter, and the influence of the dead layer and the effect of sum in cascade at the HPGe detector were studied. The correction of the dead layer values were made by varying the thickness and the radius of the germanium crystal. The detector has 75.83 cm 3 of active volume of detection, according to information provided by the manufacturer. Nevertheless, the results showed that the actual value of active volume is less than the one specified, where the dead layer represents 16% of the total volume of the crystal. A Cuno filter analysis by gamma spectrometry has enabled identifying energy peaks. Using these peaks, three radionuclides were identified in the filter: 108m Ag, 110m Ag and 60 Co. From the calibration efficiency obtained by the Monte Carlo method, the value of activity estimated for these radionuclides is in the order of MBq. (author)

Twenty one scientists attended an IEA workshop in Cincinnati, Ohio on May 8-9, 1997, which was mainly devoted to reviewing the current knowledge base on the phenonenon of radiation induced electrical degradation in ceramic insulators. Whereas convincing evidence for bulk RIED behavior has been observed by two research groups in sapphire after electron irradiation, definitive levels of bulk RIED have not been observed in high purity Al 2 O 3 by several research groups during energetic ion or fission neutron irradiation. Possible reasons for the conflicting RIED results obtained by different research groups were discussed. It was conducted that RIED does not appear to be of immediate concern for near-term fusion devices such as ITER. However, continued research on the RIED phenomenon with particular emphasis on electron irradiations of single crystal alumina was recommended in order to determine the underlying physical mechanisms. This will allow a better determination of whether RIED might occur under any of the widely varying experimental conditions in a fusion energy device. Several critical issues which are recommended for future study were outlined by the workshop attendees

Experimental and theoretical details of the foil activation method applied to neutrons flux measurements at the IEA-R1 reactor are presented. The thermal - and epithermal - neutron flux were determined form activation measurements of gold, cobalt and manganese foils; and for the fast neutron flux determination, aluminum, iron and nickel foils were used. The measurements of the activity induced in the metal foils were performed using a Ge-Li gamma spectrometry system. In each energy range of the reactor neutron spectrum, the agreement among the experimental flux values obtained using the three kind of materials, indicates the consistency of the theoretical approach and of the nuclear parameters selected.

The role of network sharing in transforming the operator business: Impact on profitability and competition

OpenAIRE

Mölleryd, Bengt G.; Markendahl, Jan

2013-01-01

This paper focuses on network sharing on mobile networks and examines the impact on profitability and competition. Network sharing refers to that operators collaborates with its competitors on part of the production of mobile services, and it could vary from passive sharing, like sharing of sites or basic facilities, to active sharing, like radio access networks or even entire networks. The paper takes a global scope on examining the extent of network sharing. The emergence of a sector with d...

Development of an artificial neural network for monitoring and diagnosis of sensor fault and detection in the IEA-R1 research reactor at IPEN; Utilizacao de redes neurais artificiais na monitoracao e deteccao de falhas em sensores do reator IEA-R1

The increasing demand on quality in production processes has encouraged the development of several studies on Monitoring and Diagnosis Systems in industrial plant, where the interruption of the production due to some unexpected change can bring risk to the operator's security besides provoking economic losses, increasing the costs to repair some damaged equipment. Because of these two points, the economic losses and the operator's security, it becomes necessary to implement Monitoring and Diagnosis Systems. In this work, a Monitoring and Diagnosis Systems was developed based on the Artificial Neural Networks methodology. This methodology was applied to the IEA-R1 research reactor at IPEN. The development of this system was divided in three stages: the first was dedicated to monitoring, the second to the detection and the third to diagnosis of failures. In the first stage, several Artificial Neural Networks were trained to monitor the temperature variables, nuclear power and dose rate. Two databases were used: one with data generated by a theoretical model and another one with data to a typical week of operation of the IEA-R1 reactor. In the second stage, the neural networks used to monitor the variables was tested with a fault database. The faults were inserted artificially in the sensors signals. As the value of the maximum calibration error for special thermocouples is {+-}0,5 deg C, it had been inserted faults of {+-} 10 C in the sensors for the reading of the variables T3 and T4. In the third stage a Fuzzy System was developed to carry out the faults diagnosis, where were considered three conditions: a normal condition, a fault of {sub 1}0 C , and a fault of + 10 C . This system will indicate which thermocouple is faulty. (author)

Electric Bike Sharing--System Requirements and Operational Concepts

Energy Technology Data Exchange (ETDEWEB)

Cherry, Christopher; Worley, Stacy; Jordan, David

2010-08-01

Bike sharing is an exciting new model of public-private transportation provision that has quickly emerged in the past five years. Technological advances have overcome hurdles of early systems and cities throughout the globe are adopting this model of transportation service. Electric bikes have simultaneously gained popularity in many regions of the world and some have suggested that shared electric bikes could provide an even higher level of service compared to existing systems. There are several challenges that are unique to shared electric bikes: electric-assisted range, recharging protocol, and bike and battery checkout procedures. This paper outlines system requirements to successfully develop and deploy an electric bike sharing system, focusing on system architecture, operational concepts, and battery management. Although there is little empirical evidence, electric bike sharing could be feasible, depending on demand and battery management, and can potentially improve the utility of existing bike sharing systems. Under most documented bike sharing use scenarios, electric bike battery capacity is insufficient for a full day of operation, depending on recharging protocol. Off-board battery management is a promising solution to address this problem. Off-board battery management can also support solar recharging. Future pilot tests will be important and allow empirical evaluation of electric bikesharing system performance. (auth)

A new IEA document for the measurement of noise immission from wind turbines at receptor locations

International Nuclear Information System (INIS)

Ljunggren, Sten

1999-01-01

A new IEA guide on acoustic noise was recently completed by an international expert group. In this guide, several practical and reliable methods for determining wind turbine noise immission at receptor locations are presented: three methods for equivalent continuous A-weighted sound pressure levels and one method for A-weighted percentiles. In the most ambitious method for equivalent sound levels, the noise is measured together with the wind speed at two locations: one at the microphone and the other at the turbine site. With this approach, the turbine levels can be corrected for background sound and the immission level can be determined at a certain target speed. Special importance is attached to the problem of correcting for background noise and to techniques for improving the signal-to-noise ratio. Thus, six methods are described which can be used in difficult situations

Exploring mHealth Participation for Emergency Response Communities

Full Text Available We explore the challenges of participation by members of emergency response communities who share a similar condition and treatment, and are called upon to participate in emergency events experienced by fellow members. Smartphones and location-based social networking technologies present an opportunity to re-engineer certain aspects of emergency medical response. Life-saving prescription medication extended in an emergency by one individual to another occurs on a micro level, anecdotally documented. We illustrate the issues and our approach through the example of an app to support patients prone to anaphylaxis and prescribed to carry epinephrine auto-injectors. We address unique participation challenges in an mHealth environment in which interventions are primarily short-term interactions which require clear and precise decision-making and constant tracking of potential participants in responding to an emergency medical event. The conflicting effects of diffused responsibility and shared identity are identified as key factors in modeling participation.

2015-01-01

Transforming health care systems to improve quality is the responsibility of nurse executives and frontline nurses alike, yet frontline nurses are often ill-prepared to share leadership and accountability needed for transformation. The aim of this qualitative study was to describe the process used to build leadership capacity of frontline nurses engaged in resolving operational failures interrupting nursing care. The leadership development process served to bridge staff transition to shared governance. This institutional review board-approved qualitative research was designed to identify the effects of mentoring by the chief nursing officer and faculty partners on leadership development of frontline nurses working to find solutions to operational failures. Twelve nurses from 4 medical surgical units participated in a Frontline Innovations' nurse-led interdisciplinary group, which met over 18 months. Transcriptions of audiotaped meetings were analyzed for emerging process and outcome themes. The transcripts revealed a robust leadership development journey of frontline nurses engaged in process improvement. Themes that emerged from the mentoring process included engagement, collaboration, empowerment, confidence, and lifelong learning. The mentoring process provided frontline nurses the leadership foundation necessary to initiate shared governance.

Truglio-Londrigan, Marie; Slyer, Jason T

2018-01-01

Shared decision-making has received national and international interest by providers, educators, researchers, and policy makers. The literature on shared decision-making is extensive, dealing with the individual components of shared decision-making rather than a comprehensive process. This view of shared decision-making leaves healthcare providers to wonder how to integrate shared decision-making into practice. To understand shared decision-making as a comprehensive process from the perspective of the patient and provider in all healthcare settings. An integrative review was conducted applying a systematic approach involving a literature search, data evaluation, and data analysis. The search included articles from PubMed, CINAHL, the Cochrane Central Register of Controlled Trials, and PsycINFO from 1970 through 2016. Articles included quantitative experimental and non-experimental designs, qualitative, and theoretical articles about shared decision-making between all healthcare providers and patients in all healthcare settings. Fifty-two papers were included in this integrative review. Three categories emerged from the synthesis: (a) communication/ relationship building; (b) working towards a shared decision; and (c) action for shared decision-making. Each major theme contained sub-themes represented in the proposed visual representation for shared decision-making. A comprehensive understanding of shared decision-making between the nurse and the patient was identified. A visual representation offers a guide that depicts shared decision-making as a process taking place during a healthcare encounter with implications for the continuation of shared decisions over time offering patients an opportunity to return to the nurse for reconsiderations of past shared decisions.

Theoretical studies aiming at the IEA-R1 reactor core conversion from high U-235 enrichment to low U-235 enrichment

The research reactors, of which the fuel elements are of MTR type, functions presently, almost in their majority with high U-235 enrichment. The fear that those fuel elements might generate a considerabLe proliferation of nuclear weapons rendered almost mandatory the conversion of highly enriched fuel elements to a low U-235 enrichment. As the IEA-R1 reactor of IPEN is operating with highly enriched fuel elements a study aiming at this conversion was done. The problems related to the conversion and the results obtained, demonstrated the technical viabilty for its realization. (E.G.) [pt

Criticality analysis of the storage tubes for irradiated fuel elements from the IEA-R1 with the MCNP code

1992-01-01

A criticality safety analysis has been carried out for the storage tubes for irradiated fuel elements from the IEA-R1 research reactor. The analysis utilized the MCNP computer code which allows exact simulations of complex geometries. Aiming reducing the amount of input data, the fuel element cross-sections have been spatially smeared out. The earth material interstice between fuel elements has been approximated conservatively as concrete because its composition was unknown. The storage tubes have been found subcritical for the most adverse conditions (water flooding and un-irradiated fuel elements). A similar analysis with the KENO-IV computer code overestimated the KEF result but still confirmed the criticality safety of the storage tubes. (author)

Energy policies of IEA countries: United States - 2007 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-02-15

The United States is the largest economy and energy user in the world. Significant developments have taken place in its energy policy since the last IEA review in 2002. Most important is the Energy Policy Act 2005 - a comprehensive energy legislation which has set new directions, including opening the way for a nuclear renaissance. Two closely connected challenges shape all debates on the nation's energy policy path: how to increase security by reducing the dependence on imported supplies; and how to address growing emissions of greenhouse gases. The United States national strategy is to find solutions largely through technology. It is a world leader in R&D and is driving development of carbon capture and storage and second-generation biofuels. But thus far, no federal government policy is in place to establish as a target an absolute reduction of CO2 emissions. The resulting uncertainty risks holding back investments into new technologies and may delay projects that are urgently required. The transport sector will be a key to a sustainable success. In the short to medium term, reduced fuel demand through higher vehicle efficiency will increase security and reduce CO2 emissions. Yet the policy for the revision of CAFE (the corporate average fuel economy) standards will leave consumers with vehicles that fall short of the technological possibilities. This review takes an in-depth look at these issues and provides recommendations on how the United States can do more to answer the challenges of both improving its security of energy supply and lowering its emissions intensity, demonstrating the significant improvements that can already be realised through existing technologies.

  Since its origination in the mid-twentieth century, the area of Artificial Intelligence (AI) has undergone a number of developments. While the early interest in AI was mainly triggered by the desire to develop artifacts that show the same intelligent behavior as humans, nowadays scientists have realized that research in AI involves a multitude of separate challenges, besides the traditional goal to replicate human intelligence. In particular, recent history has pointed out that a variety of ‘intelligent’ computational techniques, part of which are inspired by human intelligence, may be successfully applied to solve all kinds of practical problems. This sub-area of AI, which has its main emphasis on applications of intelligent systems to solve real-life problems, is currently known under the term Applied Intelligence.   The objective of the International Conference on Industrial, Engineering & Other Applications of Applied Intelligent Systems (IEA/AIE) is to promote and disseminate recent research ...

HydroShare is an online, collaborative system for open sharing of hydrologic data, analytical tools, and models. It supports the sharing of and collaboration around "resources" which are defined primarily by standardized metadata, content data models for each resource type, and an overarching resource data model based on the Open Archives Initiative's Object Reuse and Exchange (OAI-ORE) standard and a hierarchical file packaging system called "BagIt". HydroShare expands the data sharing capability of the CUAHSI Hydrologic Information System by broadening the classes of data accommodated to include geospatial and multidimensional space-time datasets commonly used in hydrology. HydroShare also includes new capability for sharing models, model components, and analytical tools and will take advantage of emerging social media functionality to enhance information about and collaboration around hydrologic data and models. It also supports web services and server/cloud based computation operating on resources for the execution of hydrologic models and analysis and visualization of hydrologic data. HydroShare uses iRODS as a network file system for underlying storage of datasets and models. Collaboration is enabled by casting datasets and models as "social objects". Social functions include both private and public sharing, formation of collaborative groups of users, and value-added annotation of shared datasets and models. The HydroShare web interface and social media functions were developed using the Django web application framework coupled to iRODS. Data visualization and analysis is supported through the Tethys Platform web GIS software stack. Links to external systems are supported by RESTful web service interfaces to HydroShare's content. This presentation will introduce the HydroShare functionality developed to date and describe ongoing development of functionality to support collaboration and integration of data and models.

Information Sharing Modalities for Mobile Ad-Hoc Networks

Science.gov (United States)

de Spindler, Alexandre; Grossniklaus, Michael; Lins, Christoph; Norrie, Moira C.

Current mobile phone technologies have fostered the emergence of a new generation of mobile applications. Such applications allow users to interact and share information opportunistically when their mobile devices are in physical proximity or close to fixed installations. It has been shown how mobile applications such as collaborative filtering and location-based services can take advantage of ad-hoc connectivity to use physical proximity as a filter mechanism inherent to the application logic. We discuss the different modes of information sharing that arise in such settings based on the models of persistence and synchronisation. We present a platform that supports the development of applications that can exploit these modes of ad-hoc information sharing and, by means of an example, show how such an application can be realised based on the supported event model.

Technology penetration and capital stock turnover. Lessons from IEA scenario analysis

Energy Technology Data Exchange (ETDEWEB)

Philibert, C. [International Energy Agency IEA, Organisation for Economic Co-operation and Development OECD, Paris (France)

2007-05-15

The aim of this paper is to reflect on the significant differences between the emissions reductions projections in mid-term and long-term scenarios, and to explore their policy implications. It draws mainly on two recent IEA publications: the 2006 World Energy Outlook (WEO), which contains energy and energy-related CO2 projections up to 2030, and the 2006-published Energy Technology Perspectives (ETP), which considers scenarios and strategies up to 2050. The analysis focuses on a comparison of the Alternative Policy Scenario of the 2006 WEO, and the various Accelerated Technology (ACT) Scenarios in the ETP. The next section provides the necessary background on these two publications and their energy-related CO2 emissions by 2030 and 2050, respectively. The third section investigates in some more depth the reasons for the large differences in the amount of emission reductions at these dates. Capital stock turnover and technology maturation lead times, in particular, are identified as primary reasons for the differences. The fourth section suggests several possible policy conclusions that can be drawn from this analysis. They include thought pieces with respect to the action required in the short-term; to the necessity of long-term signals; to the advantages and limitations of short-term targets; and to the opportunities and challenges the international community faces with respect to emission reductions in developing countries.

Shah, Gulzar H; Badana, Adrian N S; Robb, Claire; Livingood, William C

2016-01-01

Local health departments (LHDs) are striving to meet public health needs within their jurisdictions, amidst fiscal restraints and complex dynamic environment. Resource sharing across jurisdictions is a critical opportunity for LHDs to continue to enhance effectiveness and increase efficiency. This research examines the extent of cross-jurisdictional resource sharing among LHDs, the programmatic areas and organizational functions for which LHDs share resources, and LHD characteristics associated with resource sharing. Data from the National Association of County & City Health Officials' 2013 National Profile of LHDs were used. Descriptive statistics and multinomial logistic regression were performed for the 5 implementation-oriented outcome variables of interest, with 3 levels of implementation. More than 54% of LHDs shared resources such as funding, staff, or equipment with 1 or more other LHDs on a continuous, recurring basis. Results from the multinomial regression analysis indicate that economies of scale (population size and metropolitan status) had significant positive influences (at P ≤ .05) on resource sharing. Engagement in accreditation, community health assessment, community health improvement planning, quality improvement, and use of the Community Guide were associated with lower levels of engagement in resource sharing. Doctoral degree of the top executive and having 1 or more local boards of health carried a positive influence on resource sharing. Cross-jurisdictional resource sharing is a viable and commonly used process to overcome the challenges of new and emerging public health problems within the constraints of restricted budgets. LHDs, particularly smaller LHDs with limited resources, should consider increased resource sharing to address emerging challenges.

During an unexpected incident, companies should demonstrate appropriate behaviour based on predetermined and rehearsed emergency strategies. This paper describes how to select the proper strategies for emergency situations via means of the AHP-SWOT tool, where the initial SWOT analysis is conducted for the emergency management system, and the final strategies are selected via the analytic hierarchy process (AHP). Alternative response strategies comprise internal, shared and external responses. Most of the scenarios investigated for this study demanded a shared response. These findings highlight the importance of mutual aid agreements, cooperative exercises and the improvement of communication systems. Organisations can take advantage of integrated approaches to select the best strategies and tactics for normal situations in general and emergency situations in particular.

Bueno, Elaine Inacio; Ting, Daniel Kao Sun; Goncalves, Iraci M.P.

2005-01-01

The purpose of this paper is to develop a system to monitor the nuclear power of a reactor using Artificial Neural Networks. The database used in this work was developed using a theoretical model of IEA-R1 Research Reactor. The IEA-R1 is a pool type reactor of 5 MW, cooled and moderated by light water, and uses graphite and beryllium as reflector. To monitor the nuclear power the following variables were chosen: T3 . temperature above the reactor core, T4 . outlet core temperature, FE01 . primary loop flow rate and the nuclear power. The inputs are T3, T4 and FE01 and the output is the nuclear power. It was used several networks using the backpropagation algorithm. The conclusion is that the multiplayer perceptrons networks (MLPs), training by the backpropagation algorithm, can be used to solve this problem. The results obtained with the MLPs networks are satisfactory and the mean square error was in the order of 10 -4 during the network training and in the order of 10 -2 during the network testing. We intend to monitor the other variables of this model using the same methodology, and after this we will use the real database from the system to compare the results obtained with the model. The monitoring of the reactor variables is part of the development of a fault detection and isolation system which is underway and which is, by its turn, part of a comprehensive ageing management program.

The survey on the reduction measures against greenhouse effect gases was carried out which was proposed by the IEA-GHG phase 3 program. In Japan, various low emission vehicles (LEV) such as electric, methanol and natural gas vehicles are under rapid development. Like France, cost reduction and preparation of fuel filling stations are urgently necessary for the diffusion of LEVs. In New Zealand, air pollution by automobiles is not essential. The Switzerland government is promoting the diffusion of compact electric vehicles, and inhibits the use of conventional automobiles in some tourist resorts. The California state is leading the world by prescribing the bold regulation for preventing the air from pollution. In particular, the state government put automobile manufacturers under an obligation to produce zero emission vehicles (ZEV, electric vehicle) by 2% of passenger cars and trucks from 1998 and to increase ZEVs up to 10% until 2010. This report also includes two papers concerned, `Forestry management for sustainable development` and `Tropical forestry action plan after five years.` 142 refs., 19 figs., 23 tabs.

A proposal for a typology of sharing economy

Directory of Open Access Journals (Sweden)

Maira Petrini

2017-10-01

Full Text Available Purpose: to propose a typology for sharing economy that allows the characterization and classification of its main forms of manifestation. Originality/value: the theme that involves collaborative consumption and sharing economy has wide definitions with no clear establishment of boundaries between them. Part of that definition gap may occur because of the recent emergency of literature on sharing economy. Additionally, the fact that sharing economy and collaborative consumption are the newest buzzwords, several businesses started calling themselves as such. Design/methodology/approach: from the review of the literature, 11 characteristics that describe the theme were identified. In the light of those characteristics, 72 collaborative consumption websites were analyzed, representatives of the 24 collaborative consumption categories proposed by Botsman and Rogers (2010. Findings: three archetypes were identified: 1. new business models represent the new players based on technological platforms, which are the core business of the company, and generate income by charging service fees; 2. redesigned businesses are traditional market models redesigned to present time and price advantages to the consumer; 3. sharing by ideal is the archetype that best represents sustainable consumption alternative models.

The backstage work of data sharing

Conventional wisdom makes the suggestion that there are benefits to the creation of shared repositories of scientific data. Funding agencies require that the data from sponsored projects be shared publicly, but individual researchers often see little personal benefit to offset the work of creating easily sharable data. These conflicting forces have led to the emergence of a new role to support researchers: data managers. This paper identifies key differences between the socio-technical context of data managers and other "human infrastructure" roles articulated previously in Computer Supported Cooperative Work (CSCW) literature and summarizes the challenges that data managers face when accepting data for archival and reuse. Finally, while data managers' work is critical for advancing science and science policy, their work is often invisible and under-appreciated since it takes place behind the scenes.

Energy policies of IEA countries: the United Kingdom 2006 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-07-01

The United Kingdom is facing a critical moment in its energy policy: North Sea oil and gas production is declining, dependence on imported energy is increasing, while rising energy prices and climate change considerations pose further challenges. The second thematic review of the UK addresses these challenges, focusing on energy investment, energy efficiency, and the return of nuclear power to the political agenda. Almost all coal-fired and nuclear power capacity in the United Kingdom will be retired within the next 15 years. The review encourages the government to maintain its trust in the market mechanism for the delivery of required investment and security of supply. However, it also identifies the need for the government to play a more active role in setting the framework. On the demand side, the IEA considers the government's 'Energy Efficiency Commitment' (EEC) an impressive success. The EEC was introduced in 2002 and is an energy-saving programme under which suppliers must achieve efficiency targets in households. Challenges, such as the requirement that 50 per cent of savings come from low-income households, remain, and the review invites the government to investigate ways in which fuel poverty could be reduced without distorting the EEC. The review also assesses the government's shifting direction on nuclear energy and backs this new path. It argues that the development of a positive investment framework in planning and licensing - without direct intervention in investment decisions favouring nuclear - will allow investors to judge the viability of new plants. 3 apps.

In recent years, innate lymphoid cells (ILCs) have emerged as innate correlates to T cells. The similarities between ILCs and T cells indicate that lymphocytes of fundamentally distinct lineages can share core "immune modules" that encompass transcriptional circuitry and effector functions while using nonredundant complementary mechanisms of pattern recognition to enact these functions. We review modules currently recognized to be shared between ILCs and T cells. Copyright © 2016 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.

2015-12-01

This paper aims to study the influence of social media on knowledge sharing among academia. Previously, many researches have been done to explore the importance emergence of social media for public use, but there are still limited studies on how this technological advancement affects the academia. For this study, Facebook is chosen as one of the online social networking tools as the medium of knowledge sharing. To begin with, this study is started with the identification of factors that encourage the academia to share their knowledge through social media. These factors are then categorized based on Theory of Planned Behavior (TPB). After this knowledge has successfully shared, the level of successful knowledge sharing through Facebook is modeled using Fuzzy Logic. Fuzzy inputs for this study are the number of like, comment and share. Findings from this study indeed showed that there are many reasons encouraging academia to utilize social media for their work. Besides, this paper contributes new knowledge to fuzzy logic application as it is the first known research in measuring Facebook engagement for knowledge sharing purposes. In conclusion although there exist some barriers and limitations with the use of social media, academia are showing a positive shift in the application of these tools for work.

Network Analysis of an Emergent Massively Collaborative Creation on Video Sharing Website

Science.gov (United States)

Hamasaki, Masahiro; Takeda, Hideaki; Nishimura, Takuichi

The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web. As an example of massively collaborative creation, we particularly examine video development on Nico Nico Douga, which is a video sharing website that is popular in Japan. We specifically examine videos on Hatsune Miku, a version of a singing synthesizer application software that has inspired not only song creation but also songwriting, illustration, and video editing. As described herein, creators of interact to create new contents through their social network. In this paper, we analyzed the process of developing thousands of videos based on creators' social networks and investigate relationships among creation activity and social networks. The social network reveals interesting features. Creators generate large and sparse social networks including some centralized communities, and such centralized community's members shared special tags. Different categories of creators have different roles in evolving the network, e.g., songwriters gather more links than other categories, implying that they are triggers to network evolution.

Motives for participation in the sharing economy – evidence from Lithuania

Directory of Open Access Journals (Sweden)

Grybaitė Virginija

2016-12-01

Full Text Available Information and communication technologies enable the emergence of a new phenomenon called the “sharing economy”. An increasing number of articles in the media as well as debates about the positive and negative aspects of the sharing economy show a growing interest in the subject. The paper aims to review the different approaches to the definition of the sharing economy and to present the authors’ views on the concept. The reviewed literature reveals the main drivers for participating in the sharing economy. A survey was conducted to learn more about the motives of Lithuanian people participating in this concept. The survey reveals the following leading factors of using the sharing economy platforms: an easy way to make extra money; supporting individuals and/or small/independent companies; meeting new people and having an interesting experience/doing something most people haven’t tried yet. The survey also reveals that most of the respondents prefer to own things rather than share them. Despite the widespread popularity of the sharing economy platforms in the world, this phenomenon is in its infancy in Lithuania.

IEA Bioenergy task 40. Country report for the Netherlands. Update 2006

Junginger, M.; De Wit, M.; Faaij, A.

2006-09-01

Short-term objectives of the IEA Bioenergy Task 40 'Sustainable International Bio-energy Trade: Securing Supply and Demand' are amongst other objectives to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands, and also sets the first step to make an inventory of barriers as perceived by various Dutch stakeholders. The information gathered in this report is to a large extent based on existing statistics and reports from Dutch institutions. The literature data is complemented by additional information obtained from stakeholders, such as utilities, biomass traders, the port of Rotterdam, policy makers and custom institutions. In some cases, the data source was left anonymous because of the confidential nature of the data concerned. This report was first published in 2005. In this updated 2006 version, additional data has been collected for the year 2005, mainly concerning the import of biomass and renewable electricity. Also the policy section has been updated (situation September 2006), and some information on the use of biofuels has been added.

Development of a computational program to planning and control of the IEA-R1 reactor maintenance

International Nuclear Information System (INIS)

Martins, Mauro Onofre; Madi Filho, Tufic

2013-01-01

Maintenance is an essential activity in nuclear reactors. The components of safety systems of an industrial plant should have a low probability of failure, especially if there is a high risk of accidents that may cause environmental damage. In nuclear facilities, the presence of security systems is a technical specification and a requirement for their license and operation. In order to manage the entire information flow from the maintenance of the IEA-R1, a computational program (software) was developed, which not only plans and control all the maintenance, but also updates the documents and records to safeguard the quality, ensuring the safe operation of the reactor. The software has access levels and provides detailed reports of all maintenance planned and implemented, together with an individual history of the equipment during its lifetime in the facility. This work presents all the stages of the software development, description, compatibility, application, advantages and results obtained experimentally. (author)

Shared leadership and group identification in healthcare: The leadership beliefs of clinicians working in interprofessional teams.

Science.gov (United States)

Forsyth, Craig; Mason, Barbara

2017-05-01

Despite the proposed benefits of applying shared and distributed leadership models in healthcare, few studies have explored the leadership beliefs of clinicians and ascertained whether differences exist between professions. The current article aims to address these gaps and, additionally, examine whether clinicians' leadership beliefs are associated with the strength of their professional and team identifications. An online survey was responded to by 229 healthcare workers from community interprofessional teams in mental health settings across the East of England. No differences emerged between professional groups in their leadership beliefs; all professions reported a high level of agreement with shared leadership. A positive association emerged between professional identification and shared leadership in that participants who expressed the strongest level of profession identification also reported the greatest agreement with shared leadership. The same association was demonstrated for team identification and shared leadership. The findings highlight the important link between group identification and leadership beliefs, suggesting that strategies that promote strong professional and team identifications in interprofessional teams are likely to be conducive to clinicians supporting principles of shared leadership. Future research is needed to strengthen this link and examine the leadership practices of healthcare workers.

Full Text Available This study explores the emergence of triadic interactions through the example of book sharing. As part of a naturalistic study, 10 infants were visited in their homes from 3-12 months. We report that (1 book sharing as a form of infant-caregiver-object interaction occurred from as early as 3 months. Using qualitative video analysis at a micro-level adapting methodologies from conversation and interaction analysis, we demonstrate that caregivers and infants practiced book sharing in a highly co-ordinated way, with caregivers carving out interaction units and shaping actions into action arcs and infants actively participating and co-ordinating their attention between mother and object from the beginning. We also (2 sketch a developmental trajectory of book sharing over the first year and show that the quality and dynamics of book sharing interactions underwent considerable change as the ecological situation was transformed in parallel with the infants' development of attention and motor skills. Social book sharing interactions reached an early peak at 6 months with the infants becoming more active in the coordination of attention between caregiver and book. From 7-9 months, the infants shifted their interest largely to solitary object exploration, in parallel with newly emerging postural and object manipulation skills, disrupting the social coordination and the cultural frame of book sharing. In the period from 9-12 months, social book interactions resurfaced, as infants began to effectively integrate object actions within the socially shared activity. In conclusion, to fully understand the development and qualities of triadic cultural activities such as book sharing, we need to look especially at the hitherto overlooked early period from 4-6 months, and investigate how shared spaces of meaning and action are structured together in and through interaction, creating the substrate for continuing cooperation and cultural learning.

Estimating the impacts of wind power on power systems—summary of IEA Wind collaboration

Science.gov (United States)

Holttinen, Hannele

2008-04-01

Adding wind power to power systems will have beneficial impacts by reducing the emissions of electricity production and reducing the operational costs of the power system as less fuel is consumed in conventional power plants. Wind power will also have a capacity value to a power system. However, possible negative impacts will have to be assessed to make sure that they will only offset a small part of the benefits and also to ensure the security of the power system operation. An international forum for the exchange of knowledge of power system impacts of wind power has been formed under the IEA Implementing Agreement on Wind Energy. The Task 'Design and Operation of Power Systems with Large Amounts of Wind Power' is analyzing existing case studies from different power systems. There are a multitude of studies completed and ongoing related to the cost of wind integration. However, the results are not easy to compare. This paper describes the general issues of wind power impacts on power systems and presents a comparison of results from ten case studies on increased balancing needs due to wind power.

Ageing Management Programme for the IEA-R1 Reactor in São Paulo, Brazil

Ramanathan, L. V. [Institute of Energy and Nuclear Research (IPEN), National Nuclear Energy Commission (CNEN), São Paulo (Brazil)

2014-08-15

IEA-R1 is a swimming pool type reactor. It is moderated and cooled by light water and uses graphite and beryllium as reflector elements. First criticality was achieved on 16 September 1957, and the reactor is currently operating at 4.0 MW on a 64 h per week cycle. In 1996, a reactor ageing study was established to determine general deterioration of systems and components such as cooling towers, secondary cooling system, piping, pumps, specimen irradiation devices, radiation monitoring system, fuel elements, rod drive mechanisms, nuclear and process instrumentation, and safety system. The basic structure of the reactor from the original design has been maintained, but several improvements and modifications have been made over the years to various components, systems and structures. During the period 1996–2005 the reactor power was increased from 2 MW to 5 MW and the operational cycle from 8 h per day for 5 days a week to 120 h continuous per week, mainly to increase production of {sup 99}Mo. Prior to increasing reactor power, several modifications were made to the reactor system and its components. Simultaneously, a vigorous ageing management, inspection and modernization programme was put in place.

Risk sharing, public policy and the contribution of Islamic finance

Directory of Open Access Journals (Sweden)

Hossein Askari

2014-12-01

Full Text Available A major reason for the recurrent episodes of financial instability is the predominance of interest-based debt and leveraging. Financial stability is achievable through risk sharing finance instead of risk shifting that characterizes contemporary finance. A risk sharing system serves the true function of finance as facilitator of real sector activities and avoids the emergence of a “paper economy” where there is gradual decoupling of finance from the real sector. Islamic finance was initially proposed as a profit-loss sharing system, but its core principle is risk sharing. In prohibiting interest-based debt instruments, Islam grounds finance on a strong risk sharing footing. Although still a young industry that has come a long way, it has not managed to develop truly risk-sharing instruments that would allow individuals, households, and firms as well as whole economies to mitigate systematic and un-systematic risks. It is suggested that governments should intervene and issue macro-market instruments to provide their treasuries with a significant source of non-interest rate based financing while promoting risk sharing. Moreover, given that evidence across the world suggests that monetary policy’s transmission mechanism may be impaired, it is suggested that these government issued securities could also impart added potency to monetary policy.

The Sustainability of Shared Mobility in London: The Dilemma for Governance

Directory of Open Access Journals (Sweden)

Nihan Akyelken

2018-02-01

Full Text Available The role of governments in the regulation of potentially beneficial low carbon practices, such as car sharing, has proved difficult, as there are many different actors involved and as existing practices can be undermined. The mobility sector provides clear evidence of these dilemmas, as a wide range of users need to be engaged in the discourse over the innovations, and as existing governance structures may be unsuitable for addressing both the opportunities and limitations of innovation. This paper focuses on the sustainability implications of shared mobility and the need for new approaches to governance. A qualitative study of car sharing in London is used to examine the ideas, incentives, and institutions of the key actors involved in this sharing sector. The elements of change and continuity in the emerging sharing economy indicate the different possibilities for enhancing sustainable mobility. Any search for an alternative governance regime should take account of the ideational factors that would require an understanding of the different incentives needed to accommodate the full range of actors involved with the sharing economy.

Reciprocity on Demand : Sharing and Exchanging Food in Northwestern Namibia.

Science.gov (United States)

Schnegg, Michael

2015-09-01

Two competing models concerning food transfers prominent in the anthropological literature conceptualize such transfers either as sharing or as exchange. Sharing is understood as situational transactions formed through demands and unconditional giving, whereas reciprocal exchange is understood in terms of networking and keeping score. I propose that the picture is more complicated than these classifications suggests. Drawing on data collected in Northwestern Namibia, I show that sharing and reciprocal exchange are dynamically interrelated in actual food transfers. As a local norm, people can demand food from anyone, and they are typically given food in response to a demand. However, in practice, food transfer networks emerge (N = 62) that are highly reciprocal and fit the exchange model much better. Although the sharing norm makes no restrictions on whom to ask, in practice people often turn to their neighbors. Interpersonal dynamics account for why some of those ties become strongly reciprocal and others do not. Under these circumstances, unconditional sharing, a norm that has been viewed as an alternative to exchange, can lead to reciprocity via reciprocity on demand.
