    The OECD Nuclear Energy Agency (NEA) was established on 1 February 1958. Current NEA membership consists of 31 countries: Australia, Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Korea, Luxembourg, Mexico, the Netherlands, Norway, Poland, Portugal, Russia, the Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States. The European Commission also takes part in the work of the Agency. The mission of the NEA is: - to assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes; - to provide authoritative assessments and to forge common understandings on key issues, as input to government decisions on nuclear energy policy and to broader OECD policy analyses in areas such as energy and sustainable development. Specific areas of competence of the NEA include the safety and regulation of nuclear activities, radioactive waste management, radiological protection, nuclear science, economic and technical analyses of the nuclear fuel cycle, nuclear law and liability, and public information. The NEA Data Bank provides nuclear data and computer program services for participating countries. In these and related tasks, the NEA works in close collaboration with the International Atomic Energy Agency in Vienna, with which it has a Co-operation Agreement, as well as with other international organisations in the nuclear field. This document summarizes the 2014 activities of NEA. Content: 1. Message from the Director-General; 2. Nuclear Power in 2014; 3. The Fukushima Daiichi Accident and NEA Follow-up; 4.

    2016-01-01

    The year 2015 continued to be one of significant change, both in relation to the Agency and the global context within which it operates. As countries around the world plan aggressive nuclear power plant construction programmes, prepare to phase out and decommission plants, or to both build and retire plants simultaneously, issues of economics, waste management, public communication and nuclear safety continue to dominate the global discussion regarding nuclear power. As many countries work to absorb the outcome of the COP21 negotiations at the end of 2015, it is becoming increasingly likely that the future of nuclear power will be determined in great respect by non-traditional suppliers and new entrant countries. As reflected in this year's Annual Report, the NEA completed a significant revision of its management structure, which, it is hoped, will enable it to be more flexible, more efficient and more focused on the issues of greatest concern to its member countries. Our members provided input via the process of developing the new Strategic Plan of the Nuclear Energy Agency: 2017-2022, reaffirming their desire to maintain a sharp focus on nuclear safety as our most important mission area, while also reaffirming the vital importance of the NEA as a leading forum for technology cooperation, economic analysis and scientific investigation. In that respect, the NEA's new role as the institutional home of the International Framework for Nuclear Energy Cooperation (IFNEC) continues the Agency's coverage of complex issues associated with the deployment of new nuclear power plants. The NEA also launched the Nuclear Innovation 2050 initiative in 2015, through which NEA hopes to develop a coordinated international agenda for priority nuclear technology research and development on issues ranging from advanced fuel cycles to improved technology and methods for decommissioning retired plants. In all, 2015 was a year of both continued success for the NEA and a

  9. NEA Annual Report 2011

    International Nuclear Information System (INIS)

    2012-01-01

    The Nuclear Energy Agency (NEA) is a semi-autonomous body within the Organisation for Economic Co-operation and Development (OECD), located in the Paris area in France. The objective of the Agency is to assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes. 2011 was a pivotal year for the NEA and its member countries. The 11 March Tohoku earthquake and tsunami were at the origin of the Fukushima Daiichi nuclear power plant accident, with the earthquake having resulted in the loss of offsite power and the tsunami in the loss of onsite emergency power necessary to keep the cooling systems functioning. While the accident itself was not responsible for any casualties, it has affected the lives of thousands of displaced Japanese citizens and caused considerable environmental damage in the surrounding area. At the NEA, monitoring of the accident began immediately as well as working with all members to fully ascertain the technical and regulatory lessons that could be learnt. In that context, on 7-8 June 2011, the NEA hosted in co-operation with the French Presidency of the G8, a ministerial seminar on nuclear safety and a regulatory forum to discuss insights and approaches. The insights gained during the forum have strongly influenced the work of the NEA and also provided valuable input to the IAEA ministerial conference and subsequent action plan. At present, the three NEA standing technical committees most involved in Fukushima follow-up work are the Committee on Nuclear Regulatory Activities, the Committee on Radiation Protection and Public Health, and the Committee on the Safety of Nuclear Installations. A number of activities are underway in the areas of nuclear regulation, nuclear safety and research, crisis communication, radiological protection, decontamination and

    International Nuclear Information System (INIS)

    1983-01-01

    This paper is an introduction to the NEA data bank. The essential programs and data for nuclear energy calculations are available from the Data Bank. The Data Bank's role, in co-operation with other centers, is to protect the technological capital represented by the programs and data in its collection, which is unique in covering nearly the whole field of reactor physics at a single center (Saclay). The compilation and exchange of experimental and evaluated neutron and other nuclear data is carried out through a world-wide information network. The tasks now assigned to the Data Bank are in the areas of computer program packaging, neutron data compilation, assembly and benchmark testing of the Joint Evaluated File (JEF) of neutron cross-section data, and servicing the NEA scientific committees, as well as providing a computer service to the main NEA secretariat. In all areas the emphasis is on developing a ''value added'' element to the incoming data or computer codes, by validation documentation and presentation of information in a convenient standard form. The services offered by the Data Bank and the computers used by the Data Bank are presented

    International Nuclear Information System (INIS)

    2014-01-01

    The Nuclear Energy Agency (NEA) is a semi-autonomous body within the Organisation for Economic Co-operation and Development (OECD), located in the Paris area in France. The objective of the Agency is to assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes. 2013 was a year of continuing progress by the OECD Nuclear Energy Agency in a number of important areas, marked in particular by an increased scope and reach. Following the accession of the Russian Federation on 1 January 2013, the 31 members of the Agency now account for 90% of installed nuclear power generating capacity in the world, further expanding the significant international role that the NEA can play in the scientific, technological, legal and safety-related aspects of nuclear energy. The NEA is a central part of concerted international efforts to enhance co-operation in the nuclear energy field. As part of these efforts, in 2013 the NEA and the China Atomic Energy Authority (CAEA) signed a Joint Declaration on Co-operation in the Field of Peaceful Uses of Nuclear Energy. The purpose of this co-operation is to enhance the exchange of experience and information at the international level so as to make nuclear power safer, and to ensure robust scientific, technological and legal bases for its development and use in an environmentally friendly and economical manner. The NEA remains fully committed to these objectives, and in view of ongoing work following the 2011 accident at the Fukushima Daiichi nuclear power plant, the Agency published in September 2013 a summary of key actions and member country responses entitled The Fukushima Daiichi Nuclear Power Plant Accident: OECD/NEA Nuclear Safety Response and Lessons Learnt. NEA actions in response to the accident have primarily been led by the three committees

  3. Human exploration of NEA: why and how?

    Science.gov (United States)

    Viscio, M. A.; Casacci, C.; Ferro, C.

    The human exploration of multiple deep space destinations, and among them Near Earth Asteroids (NEA), in view of the final challenge of sending astronauts to Mars, represents a current and consistent study domain. NEAs represent interesting targets, not only for the high level scientific return of such missions, but also for advanced technologies demonstration. Accordingly, the NEA mission described in this paper is conceived as an intermediate step before a human mission to the Red Planet and, in this regard, several technologies required for Mars are implemented, in order to test and validate them in significant environment, but at a closer and easier destination. Another crucial aspect to be considered, when dealing with asteroids, is related to planetary defense: even if the probability of an impact with the Earth is very low, this possibility does actually exist. A human mission as the one described in this paper would represent a chance for the development and test of technologies and techniques to be used for asteroid collision avoidance. The paper starts discussing the main objectives of a NEA mission, highlighting the benefits of the human presence. A reference human mission is then described, in terms of strategy, architecture and concept of operations, with particular attention to NEA collision avoidance issue. In the last part, the idea of exploiting virtual reality in support of the mission definition and execution is discussed.

  4. NEA, Nuclear law and information processing

    International Nuclear Information System (INIS)

    Reyners, P.

    1977-01-01

    NEA has for many years now been collating information on, and analysing, laws and regulations on the peaceful uses of nuclear energy, and this work has resulted in a series of publications. However, as seen by the multiplication of computer-based legal information centres, both at national and international level, conventional information systems are no longer adequate to deal with the increasing volume of information and with users' needs. In view of the particular aspects of nuclear law and of its own availabilities, NEA has endeavoured to make the best possible use of existing structures by opting for participation in the IAEA International Nuclear Information System rather than by creating a specialised centre. Before becoming operational, the arrangements concluded between NEA and IAEA required that the INIS rules be altered somewhat to take account of the specific problems raised by treatment of legal literature and also to improve the quality of information provided to users.

    2017-01-01

    The NEA launched its Nuclear Innovation 2050 (NI2050) Initiative with the aim of identifying research and development (R and D) strategies and associated priorities to achieve commercial readiness of innovative, sustainable nuclear fission technologies in a fast and cost-effective way. As defined at the beginning of the process, these R and D strategies would be elaborated with NEA stakeholders at large, in particular involving nearly all NEA committees, nuclear research organisations, industry, regulators and technical safety organisations. The NI2050 Initiative has evolved over the last year to become an NEA incubator for the selection and development of a number of large nuclear fission R and D programs (and infrastructures) that can support the role of nuclear energy in a low carbon future, mainly by accelerating innovation and the market deployment of technologies. This article provides a brief overview and the next steps of the initiative, which has reached the stage where more concrete outcomes might now be expected, in particular in terms of programs of action to be proposed for co-operative implementation

    2006-01-01

    The OECD Nuclear Energy Agency (NEA) Data Bank is part of an international network of data centres in charge of the compilation and dissemination of basic nuclear data. The NEA offers easy access to the main nuclear databases with bibliographical information, evaluated libraries, e.g. the Joint Evaluated Fission and Fusion (JEFF) library, and experimental data in the EXFOR database, comprising published neutron induced as well as charged particle induced nuclear reaction data. The NEA Working Party on international nuclear data Evaluation Co-operation (WPEC) is established to promote the exchange of information on nuclear data evaluations, measurements, nuclear model calculations and validation. WPEC provides a framework for co-operative activities between six major evaluation projects (BROND, CENDL, Endf, FENDL, JEFF and JENDL). The NEA Data Bank administrates the collection and validation as well as the distribution of the JEFF library. The latest version, JEFF-3.1, was released in May 2005 and it contains a neutron data library, a proton data library and thermal scattering law data. The special purpose library on activation data contains 774 nuclei with over 12600 neutron induced reactions. Included is also radioactive decay data, with 3852 isotopes, and spontaneous and neutron induced fission yield data. The full documentation of the library is being prepared for publication in 2006. Processed JEFF-3.1 data files in ACE format, mainly for reactor physics applications, have been prepared and were distributed in spring 2006 with documentation. The processed files have been validated for criticality calculations, as well as for radiation physics application. The detailed analysis of the validation results will be very useful for improving the accuracy of evaluated data libraries. The display program JANIS has been developed at the NEA, and the latest version (JANIS-2.21) was released in October 2005. JANIS is designed to facilitate the visualisation and

  9. Joint IAEA/NEA IRS guidelines

    International Nuclear Information System (INIS)

    1997-01-01

    The Incident Reporting System (IRS) is an international system jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organization for Economic Cooperation and Development (OECD/NEA). The fundamental objective of the IRS is to contribute to improving the safety of commercial nuclear power plants (NPPs) which are operated worldwide. This objective can be achieved by providing timely and detailed information on both technical and human factors related to events of safety significance which occur at these plants. The purpose of these guidelines, which supersede the previous IAEA Safety Series No. 93 (Part II) and the NEA IRS guidelines, is to describe the system and to give users the necessary background and guidance to enable them to produce IRS reports meeting a high standard of quality while retaining the high efficiency of the system expected by all Member States operating nuclear power plants

  14. New Early Cycladic Figurine At Nea Styra

    Science.gov (United States)

    Kosma, M.

    The existence of an Early Bronze Age coastal site in the district of Nea Styra has been known since the end of the 19th century when three marble figurines of early Cycladic type had been found in the area. During the 20th century survey investigations conducted by Greek and foreign archaeologists offered new evidence which demonstrated the significance of the site during the Early and Middle Helladic periods. A new figurine of early Cycladic type, which recently came to light at Nea Styra due to the control of building permits by the 11th Ephorate of Prehistoric and Classical Antiquities, reaffirms the identification of the area as one of the three most important sites on Euboea during the Early Helladic II period. This paper focuses on a newly discovered figurine and its typological character. The new find is compared to the figurines that had been found in the 19th century at Nea Styra. We hope that the scheduled excavations on the private land plot where the new figurine was found will offer new data leading to a better understanding of the character of the Early Helladic settlement in this part of southern Euboea.

It encompasses four main areas - nuclear safety technology; nuclear licensing; radiation protection; and waste management - with three principal objectives: to promote exchanges of technical information in order to enlarge the data base for national decision making; to improve co-ordination of national R and D activities with emphasis on international standard problem exercises, and to promote international projects; to develop common technical, administrative and legal approaches to improve compatibility of safety and regulatory practices

  16. Peritonite bacteriana espontânea

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available A peritonite bacteriana espontânea ocorre em 30% dos cirróticos com ascite e, neste grupo, apresenta altas taxas de morbidade e mortalidade. Os fatores predisponentes incluem a diminuição da defesa imunológica encontrada no homem nas fases avançadas da cirrose, o supercrescimento da flora intestinal e a translocação bacteriana da luz dos intestinos aos linfonodos mesentéricos. As manifestações clínicas variam de graves a leves ou ausentes, sendo sempre necessária a análise do líquido ascítico. O diagnóstico de peritonite bacteriana espontânea se faz pela contagem de neutrófilos > 250/mm³ no líquido ascítico associado ou não ao crescimento de bactéria na cultura. As enterobactérias predominam como causa da infecção, sendo a Echerichia coli a bactéria mais freqüentemente isolada. O diagnóstico precoce e o tratamento adequado provocaram a queda das taxas de mortalidade nas duas últimas décadas. O uso endovenoso de cefalosporinas de terceira geração mostra-se eficaz em 70% a 95% dos casos. A recorrência de peritonite bacteriana espontânea é comum e pode ser prevenida com norfloxacina oral, de uso contínuo. O surgimento de resistência bacteriana tem estimulado a procura de novas opções para a profilaxia da peritonite bacteriana espontânea; os probióticos constituem nova abordagem promissora, mas que necessita melhor avaliação. Recomenda-se a profilaxia primária de curta duração aos cirróticos com ascite que apresentem episódio de hemorragia digestiva alta.

  17. NEA incident reporting system: Three years' experience

    1984-01-01

    The paper presents an overview of the NEA Incident Reporting System (IRS) which was set up to collect, assess and disseminate on safety-related incidents in nuclear power plants. The IRS information exchange is significant in two senses. First, it enables regulatory authorities and utilities in participating countries to take appropriate action to prevent the reported mishaps occurring again elsewhere. Secondly, the continuous collection and systematic analysis of such information allows identification of areas of concern where safety research should be strengthened. There are two stages in the IRS information exchange. First, the national IRS Co-ordinator selects information on significant incidents, in accordance with a common reporting threshold, from the abnormal occurrences reported to the regulatory body, to be distributed through the NEA Secretariat. This screening is intended to exclude minor events, so that only significant information is sent to participating countries. Secondly, a group of experts periodically reviews the incidents reported during the preceding twelve months to identify major areas of concern. To assist this process, a computer-based data retrieval system is being developed for IRS incident reports. The paper gives some details of the IRS mechanism and discusses reporting criteria and the information included in a report. Areas of concern derived from reported incidents, an outline of the data retrieval system, and examples of feedback of lessons learned and possibilities for international co-operation are also discussed.

  1. The NEA sorption data base (SDB)

    International Nuclear Information System (INIS)

    Ruegger, B.; Ticknor, K.

    1992-01-01

    The current NEA Sorption Data Base is developed to replace the former International Sorption Information Retrieval System (ISIRS) initiated at Pacific Northwest Laboratory and contains about 11,000 distribution coefficients with corresponding experimental condition parameters describing sorption of key nuclides for a large variety of solid and liquid phases. The SDB is designed to run on a micro-computer using the commercially available database software dBASE III Plus. For each recorded sorption experiment, the SDB provides a bibliographical reference, the most complete characterization of the solid and liquid phases available, a description of the experimental conditions and the distribution coefficient or retardation factor for each element studied. When available, parameters such as temperature, initial radionuclide concentration, pH, Eh, contact time, solid to solution ratio, sample origin, oxidation state and type of solution are included. The SDB provides information for a wide variety of rocks or geological materials, buffer backfill candidates, concretes/cements, elements (Am, Cs, Co, I, Np, Pu, Ra, Sr, Se, Tc, U and, to a lesser extent, Ag, Ba, C, Ce, Eu, Fe, Mn, Mo, Na, Nb, Ni, Pd, Pm, Ru, Sb, Sn, Y, Zn, and Zr), or radioisotopes. A compilation of sorption data like SDB provide a readily available source of data for radioactive waste repository performance assessments when site specific data are not available or essential, for example, during a site selection phase. 2 appendices

  2. NEA activities on medical isotope supply issues

    Medical radioisotopes play a vital role in modern medical practices. One of their principal uses is for nuclear diagnostic imaging techniques. These techniques are powerful and non-invasive, allowing the identification of common diseases such as heart conditions and cancer at an early stage, tracking disease progression and providing predictive information about likely success of a therapy. Such techniques enable precise and accurate management of the disease and may significantly assist in the medical decision-making process, for example removing the need for surgical intervention to obtain diagnostic information. Every year, 46 million people are estimated to benefit globally from such nuclear medicine testing. However, over the last few years there have been a number of supply shortages of Molybdenum-99 (Mo-99) and its decay product, Technetium-99m (Tc-99m), the most widely used medical radioisotope. These isotopes decay within a matter of days; therefore they must be produced continually in order to meet demand. Most recently, the unexpected extended shutdown of Canada's NRU research reactor - which produces approximately 35 percent of world Mo-99 supply - has compounded existing concerns regarding the supply reliability of these medical radioisotopes. Currently, five reactors between 42 and 52 years old produce over 95 percent of the world's supply of Mo-99 and face challenges in maintaining a continuous supply to the health community. As outlined above, disruptions in this supply chain have affected the availability of vital medical testing for millions of patients around the world. On 29-30 January 2009, the NEA hosted a workshop on Security of Supply of Medical Radioisotopes at the request of the Government of Canada. The workshop assembled an international group of experts to identify challenges faced in providing a reliable supply of Mo-99 and Tc-99m and measures that should be taken to ensure such reliability. Workshop participants discussed a wide

    The OECD Nuclear Energy Agency (NEA) Data Bank is an international centre of reference for its member countries with respect to basic nuclear tools, such as computer codes and nuclear data. The Data Bank is part of an international network of data centres in charge of the compilation and dissemination of basic nuclear data. The NEA nuclear data services include the collection of data, validation and distribution of the Nuclear Data libraries via the NEA web-site, offering easy access to databases containing bibliographical and experimental information, as well as evaluated libraries, e.g., the Joint Evaluated Fission and Fusion (JEFF) library. The selection and distribution of chemical thermodynamic data for radioactive waste management applications is the subject of the Thermochemical Database Project (TDB), supported by 17 organisations in 12 member countries and co-ordinated by the NEA Data Bank. In support of data evaluation, and generation of project oriented data libraries, relevant computer codes in the field of nuclear models, experimental data processing and evaluated data processing are made available to experts with the support of the member countries. Large collections of benchmark experiments for data and code validation are also available from the NEA in areas such as criticality safety (ICSBEP), radiation shielding (SINBAD), fuel performance (IFPE) and reactor physics (IRPhE). The NEA Working Party on international nuclear data Evaluation Co-operation (WPEC) provides a framework for co-operative activities between the six major evaluation projects (BROND, CENDL, Endf, FENDL, JEFF and JENDL).

    Since 2006, the European Near Earth Asteroids Research (EURONEAR) project has been contributing to the research of near-Earth asteroids (NEAs) within a European network. One of the main aims is the amelioration of the orbits of NEAs, and starting in 2014 February we focus on the recovery of one-opposition NEAs using the Isaac Newton Telescope (INT) in La Palma in override mode. Part of this NEA recovery project, since 2014 June EURONEAR serendipitously started to discover and secure the first NEAs from La Palma and using the INT, thanks to the teamwork including amateurs and students who promptly reduce the data, report discoveries and secure new objects recovered with the INT and few other telescopes from the EURONEAR network. Five NEAs were discovered with the INT, including 2014 LU14, 2014 NL52 (one very fast rotator), 2014 OL339 (the fourth known Earth quasi-satellite), 2014 SG143 (a quite large NEA), and 2014 VP. Another very fast moving NEA was discovered but was unfortunately lost due to lack of follow-up time. Additionally, another 14 NEA candidates were identified based on two models, all being rapidly followed-up using the INT and another 11 telescopes within the EURONEAR network. They include one object discovered by Pan-STARRS, two Mars crossers, two Hungarias, one Jupiter trojan, and other few inner main belt asteroids (MBAs). Using the INT and Sierra Nevada 1.5 m for photometry, then the Gran Telescopio de Canarias for spectroscopy, we derived the very rapid rotation of 2014 NL52, then its albedo, magnitude, size, and its spectral class. Based on the total sky coverage in dark conditions, we evaluate the actual survey discovery rate using 2-m class telescopes. One NEA is possible to be discovered randomly within minimum 2.8 deg2 and maximum 5.5 deg2. These findings update our past statistics, being based on double sky coverage and taking into account the recent increase in discovery.

    The Information System on Occupational Exposure (ISOE) was launched by the Organization for Economic Cooperation and Development (OECD), Nuclear Energy Agency (NEA) on 1 January, 1992, to facilitate the communication of dosimetric and ALARA implementation data among nuclear utilities around the world. After two years of operation the System has become a mature interactive network for transfer of data and experience. Currently, 37 utilities from 12 countries, representing 289 power plants, and 12 national regulatory authorities participate in ISOE. Agreements for cooperation also exist between the NEA and the Commission of the European Communities (CEC), and the Paris Center of the WOrld Association of Nuclear Operators (WANO-PC). In addition, the International Atomic Energy Agency (IAEA) is acting as a co-sponsor of ISOE for the participation of non-NEA member countries. Three Regional Technical Centres, Europe, Asia, and Non-NEA member countries, serve to administer the system. The ISOE Network is comprised of three data bases and a communications network at several levels. The three ISOE data bases include the following types of information: NEA1 - annual plant dosimetric information; NEA2 - plant operational characteristics for dose and dose rate reduction; and NEA3 - job specific ALARA practices and experiences. The ISOE communications network has matured greatly during 1992 and 1993. In addition to having access to the above mentioned data bases, participants may now solicit information on new subjects, through the Technical Centres, from all other participants on a real-time basis. Information Sheets on these studies are produced for distribution to all participants. In addition, Topical Reports on areas of interest are produced, and Topical Meetings are held annually.

    RF guns have proven useful in multiple accelerator applications, and are an attractive electron source for the ILC. Using a NEA GaAs photocathode in such a gun allows for the production of polarized electron beams. However the lifetime of a NEA cathode in this environment is reduced by ion and electron bombardment and residual gas oxidation. We report progress made with studies to produce a RF gun using a NEA GaAs photocathode to produce polarized electron beams. Attempts to reduce the residual gas pressure in the gun are discussed. Initial measurements of ion flux through the cathode port are compared with simulations of ion bombardment. Future directions are also discussed.

    La criptococosis cutánea es una micosis propia de pacientes inmunodeprimidos, sobre todo aquellos con infección por el virusde la inmunodeficiencia humana (VIH). Sin embargo, existen casos infrecuentes de criptococosis cutánea en pacientes inmunocompetentes, que suelen simular otras dermatosis, lo que retrasa su diagnóstico y tratamiento. Presentamos el caso de un varón pluripatológico de 79 años, con úlceras dolorosas en dorso de mano derecha que no respondían a tratamientos tópicos. A través del estudio histopatológico y micológico se alcanzó el diagnóstico de criptococosis cutánea primaria, lográndose la remisión de las lesiones tras 6 meses de tratamiento con fluconazol.

    The Nuclear Energy Agency, a member of the OECD family, has as mission, in line with the overall aim of the OECD, to assist Agency's member countries in maintaining and further developing through international cooperation, the scientific, technological and legal bases for a safe, environmentally friendly and economic use of nuclear energy for peaceful purposes. Our members include very advanced nuclear countries and represent a big part of the world's nuclear capacity. In addition, we have a well established and formal relationship with the Russian Federation and the IAEA. Two years ago, the NEA celebrated its 50th anniversary of providing assistance to its member countries in supporting the safe use of nuclear power. Nuclear power will remain a key part of the energy mix for many decades to come and, as such, the NEA looks forward to continuing its value-adding work in the field of nuclear power. Korea joined the NEA in 24 May, 1993. While the NEA is satisfied that we have in place an effective process of work, we are always looking for ways to improve. This is the reason why we have since 1999 a series of strategic plans in order to better focus on the objectives that member countries assign to the Agency for meeting the economical, environmental and societal challenges of the coming years. The important changes that have occurred in the energy and nuclear landscapes, as well as in the OECD framework, are the basis for these revisions insofar as they influence the NEA's role and activities. We are now completing the process for the new Strategic Plan which will apply from 2011 to 2017. Nuclear safety and regulation is and will continue to be the first priority of the Agency. The NEA will assist member countries to continue sharing information, best practices and lessons learned to enhance nuclear safety worldwide

  14. NEA international peer reviews of post-accident protection policy

    Lazo, T.

    2011-01-01

    For many years, the NEA has offered international peer reviews of national, high-level radioactive waste management policies and approaches. Until recently, this service had not been requested in the area of radiological protection. However, the 3. International Nuclear Emergency Exercise (INEX-3, 2005-2006) addressed post-accident consequence management for the first time in a broad, international sense, and helped generate significant national reflections in this area. In particular, in 2005 the French government began an extensive programme of post-emergency consequence management planning, resulting in a draft national policy to address such situations. The Finnish government used the INEX-3 exercise as a vehicle to discuss post-emergency consequence management with a broad group of governmental and private stakeholders, and also began to develop national policy in this area. In order to further refine national efforts, the French Nuclear Safety Authority (ASN) invited the NEA to perform in April 2011 its first international peer review in the radiological protection area focusing on its post-emergency consequence management policy under development. Finnish experts participated in this peer review team, and as a result, subsequently invited the NEA to perform an international peer review of its developing policy in this area in September 2011. These draft national policies and their international peer reviews are briefly presented in this paper. Feedback from both the French ASN and the Finnish STUK suggests that the detailed, external input provided by the international peer review teams have been extremely valuable in refining the content of the guides so that they are more clear, concise, understandable and implementable. It should be recalled that both national policy documents reviewed are far more detailed and extensive than described here. The intent of this article was not to provide a review of the national policies themselves, but rather to give an

Verificou-se por testes de imunidade cruzada que as três amostras eram idênticas. Prossegiu-se então nas passagens com apenas uma das amostras. 3 — O poder infetante aumenta com o número de passagens: o período médio de incubação diminui e aumenta a letalidade. 4 — A infecção espontânea e experimental é descrita. A doença parece ser mais comum em animais jovens. O período de incubação varia de 5 a 30 dias. Às vêzes observa-se uma fase prodromica: fraqueza, menor atividade, dificuldade em andar; geralmente surge a paralisia flácida sem sintomas prévios, na grande maioria das vêzes, nos membros posteriores. Três formas clínicas foram observadas: super-aguda, aguda e crônica. 5 — Em camundongos normais o vírus pode ser demonstrado nas fezes e nos intestinos. Ele é comum no tubo digestivo e só ocasionalmente invade o sistema nervoso central, ou melhor, a encefalomielite e primàriamente uma doença do trato digestivo no qual a invasão do SNC é um acidente. 6 — O vírus passa através de velas de CHAMBERLAND L3 e L5, em BER KEFED V, N e W e em filtro Seitz EK, a suspensão sendo tão ativa como antes da filtração.

    The OECD Nuclear Energy Agency (NEA) Data Bank participates in the production of data and their distribution to users including the collection and validation as well as the distribution of the Joint Evaluated Fission and Fusion (JEFF) library. The JEFF project has evolved from two separate projects, namely the European Fusion File (EFF) and the Joint Evaluated File (JEF), with the release of JEFF-3.1, in May 2005. The NEA also provides tools for the EFF project, such as computer codes for nuclear energy and radiation physics applications. Of special interest for fusion applications are the integral experiments collected in the SINBAD database, with radiation shielding and dosimetry experiments including many fusion neutronics shielding experiments. In this paper an overview will be given of the NEA, and some examples of nuclear data services offered, such as the SINBAD database. JANIS, a display program evaluated and experimental data developed at the NEA will be mentioned briefly. The main emphasis will be given to the EFF project including the contents of the new JEFF-3.1 library, released in May 2005. Examples of recent work are given as well as a discussion on the forth-coming evaluation efforts among the EFF collaborators.

    The OECD Nuclear Energy Agency (NEA) Data Bank is part of an international network of data centres in charge of the compilation and dissemination of basic nuclear data. Through its activities in the reaction data field, the NEA participates in the production of data and their distribution to its users. The NEA Data Bank administrates the collection and validation as well as the distribution of the Joint Evaluated Fusion and Fission (JEFF) library. The JEFF project has evolved from two separate projects, namely the European Fusion File (EFF) and the Joint Evaluated File (JEF), to JEFF with the latest release of the library, JEFF-3.1, in May 2005. The EFF Project is a collaborative project with work funded by the European Fusion Development Agreement (EFDA). The tasks within the project comprise new data evaluation and verification of activation and transport data, calculation methods and validation via integral experiments. The EFF project brings together all available expertise in Europe, relating to the nuclear data requirements of existing and future fusion devices. EFF contributed greatly to the successful release of the internationally recognised nuclear data library JEFF-3.1. The NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) is established to promote the exchange of information on nuclear data evaluations, measurements, nuclear model calculations and validation. WPEC provides a framework for co-operative activities between the participating projects, such as the high priority request list that is a collection of experimental data requests of special interest in a certain project, such as JEFF or ITER. The NEA provides also computer program services for nuclear energy and radiation physics applications. Of special interest for fusion applications are the integral experiments, such as SINBAD, with radiation shielding and dosimetry experiments including many fusion neutronics shielding experiments.

    The objectives of the Nuclear Energy Agency of the OECD in the area of radioactive waste management are to promote studies and improve the data available to support national programmes, to co-ordinate national activities, to promote international projects, and to improve the general level of understanding of waste management issues. The NEA programme concentrates on the disposal of waste and responds to objectives at three levels: sharing of information and organization of joint analytical studies through expert meetings, preparation of technical reports and analysis and dissemination of data; establishment of joint research and development projects designed to support national programmes; and discussion of current issues and strategies, particularly through the Radioactive Waste Management Committee acting as a specialized internatonal forum. The paper discusses, through various specific examples, how the objectives are met. In addition, the paper describes current NEA activities which have not been reported in other papers during the Conference. (author)

    Several OECD Member Countries have agreed to establish the OECD/NEA 'Component Operational Experience, Degradation and Ageing Programme' (CODAP) to encourage multilateral co-operation in the collection and analysis of data relating to degradation and failure of metallic piping and non-piping metallic passive components in commercial nuclear power plants. The scope of the data collection includes service-induced wall thinning, part through-wall cracks, through-wall cracks with and without active leakage, and instances of significant degradation of metallic passive components, including piping pressure boundary integrity. CODAP is the continuation of the 2002-2011 'OECD/NEA Pipe Failure Data Exchange Project' (OPDE) and the Stress Corrosion Cracking Working Group of the 2006-2010 - OECD/NEA SCC and Cable Ageing project - (SCAP). OPDE was formally launched in May 2002. Upon completion of the 3. Term (May 2011), the OPDE project was officially closed to be succeeded by CODAP. In May 2011, 13 countries signed the CODAP first Term agreement. The first Term (2011-2014) work plan includes the development of a web-based relational event database on passive, metallic components in commercial nuclear power plants, a web-based knowledge base on material degradation, codes and standards relating to structural integrity and national practices for managing material degradation. The work plan also addresses the preparation of Topical Reports to foster technical cooperation and to deepen the understanding of national differences in ageing management. These Topical Reports are in the public domain and available for download on the NEA web site. Published in 2014, a first Topical Report addressed flow accelerated corrosion (FAC) of carbon steel and low alloy steel piping. A second Topical Report addresses operating experience with electro-hydraulic control (EHC) and instrument air (IA) system piping

    Humans are considered as a system in the design of any deep space exploration mission. The addition of many potential near asteroid (NEA) destinations to the existing multiple mission architecture for Lunar and Mars missions increases the complexity of human health and performance issues that are anticipated for exploration of space. We suggest that risks to human health and performance be analyzed in terms of the 4 major parameters related to multiple mission architecture: destination, duration, distance and vehicle design. Geological properties of the NEA will influence design of exploration tasks related to sample handling and containment, and extravehicular activity (EVA) capabilities including suit ports and tools. A robotic precursor mission that collects basic information on NEA surface properties would reduce uncertainty about these aspects of the mission as well as aid in mission architecture and exploration task design. Key mission parameters are strongly impacted by duration and distance. The most critical of these is deep-space radiation exposure without even the temporary shielding of a nearby large planetary body. The current space radiation permissible exposure limits (PEL) limits mission duration to 3-10 months depending on age, gender and stage of the solar cycle. Duration also impacts mission architectures including countermeasures for bone, muscle, and cardiovascular atrophy during continuous weightlessness; and behavioral and psychological issues resulting from isolation and confinement. Distance affects communications and limits abort and return options for a NEA mission. These factors are anticipated to have important effects on crew function and autonomous operations, as well as influence medical capability, supplies and training requirements of the crew. The design of a habitat volume that can maintain the physical and psychological health of the crew and support mission operations with limited intervention from earth will require an

    2010-11-01

    The OECD Nuclear Energy Agency (NEA) seeks to assist its member countries in developing safe, sustainable and societally acceptable strategies for the management of all types of radioactive materials, with particular emphasis on the management of long-lived waste and spent fuel and on decommissioning of disused nuclear facilities. The programme of work in these areas is carried out for the most part by the Radioactive Waste Management Committee (RWMC) assisted by three working parties: - The Forum on Stakeholder Confidence (FSC). - The Integration Group for the Safety Case (IGSC). - The Working Party on Decommissioning and Dismantling (WPDD). Other NEA Committees also have interests in this field: the Committee on Radiation Protection and Public Health (CRPPH) and the Nuclear Development Committee (NDC). The OECD/NEA is at the forefront in addressing both the technical and societal requirements for durable and sustainable waste management and decommissioning solutions. Through the RWMC it provides a neutral forum where policy makers, regulators and implementing organisations can discuss issues of common interest and develop solutions that meet the diverse needs of its member countries

    Since the use of nuclear technology for a wide range of purposes is increasing, with many NEA member countries constructing or planning to construct new generation nuclear power plants, the NEA is developing the NEA Nuclear Education, Skills and Technology (NEST) Framework in partnership with its member countries. This initiative will help address important gaps in nuclear skills capacity building, knowledge transfer and technical innovation in an international context. It will also assist countries examining long-term options to manage high-level radioactive waste and spent nuclear fuel, as well as better ways to decommission old facilities. The majority of these countries are likewise facing challenging issues in other fields related to nuclear energy, ranging from medicine to the environment. The need to develop and apply innovative technologies in order to meet these challenges is apparent in all these areas. At the same time, advances in fields such as materials science and instrumentation, linked with the availability of high-performance computing, have opened up new avenues ripe for exploitation, which makes for a combination of exciting new areas of innovation alongside longstanding challenges in the nuclear field. The goal of NEST is to energise advanced students, post-doctoral appointees and young professionals to pursue careers in the nuclear field

    2017-09-01

    JANIS (JAva-based Nuclear Data Information System) software is developed by the OECD Nuclear Energy Agency (NEA) Data Bank to facilitate the visualization and manipulation of nuclear data, giving access to evaluated nuclear data libraries, such as ENDF, JEFF, JENDL, TENDL etc., and also to experimental nuclear data (EXFOR) and bibliographical references (CINDA). It is available as a standalone Java program, downloadable and distributed on DVD and also a web application available on the NEA website. One of the main new features in JANIS is the scripting capability via command line, which notably automatizes plots generation and permits automatically extracting data from the JANIS database. Recent NEA software developments rely on these JANIS features to access nuclear data, for example the Nuclear Data Sensitivity Tool (NDaST) makes use of covariance data in BOXER and COVERX formats, which are retrieved from the JANIS database. New features added in this version of the JANIS software are described along this paper with some examples.

Que elementos caracterizam o tráfico como escravidão contemporânea? Por outro lado, se o Tráfico é uma forma contemporânea de escravidão, temos de reconhecer a existência de uma prática que foi objeto de “proibição”, “abolição”, há mais de 150 anos: a escravidão. Uma prática condenada por diversas normas internacionais, tanto a nível universal quanto regional e nacional. Diante da inegável existência de formas contemporâneas de escravidão no cenário internacional, nos preguntamos se este fato não seria um exemplo da desordem internacional, produzida pela ausência de ação (ou baixa eficácia do ator principal para sua erradicação: o Estado. A estes efeitos, para a presente investigação, partimos da hipótese de que o Tráfico de seres humanos é um exemplo manifesto da desordem internacional. Para fundamentar nossa hipótese, a presente tese se encontra estruturada em quatro partes que guardam devida relação entre si. Na primeira, realizamos una análise teórica das Relaciones internacionais, no marco de nosso estudo: o Tráfico de mulheres como forma contemporânea de escravidão, um exemplo da desordem internacional. Esta análise está fundamentada, tanto desde a perspectiva construtivista das relações internacionais, com uma aproximação à teoria dos regímenes internacionais, quanto desde a humanização do Direito internacional contemporâneo. Na segunda, desenvolvemos o conceito de escravidão, suas formas análogas e do trabalho forçado. Na terceira, aprofundamos a análise no Tráfico de seres humanos, particularmente no tráfico de mulheres para fins de exploração sexual, no qual examinamos a evolução conceitual e as sinergias com outras formas contemporâneas de escravidão; sua manifestação como uma forma de violência contra a mulher e uma violação sistemática de

  16. NEA impactors: what direction to they come from?

    Harris, Alan

    2018-04-01

    One might expect, if Earth-crossing NEAs are "thermalized" by prior close scattering encounters with the Earth, that final impact trajectories would be isotropic in direction. But orbital perturbations and other sources of entry and exit to the Earth-crossing zone are faster acting that thermalization, so the actual distribution of impacting orbits is quite anisotropic. I have studied impactor directions by adjusting the orbits of known Earth-crossing PHAs slightly to put them on intersecting orbits and then computed the direction of approach to the Earth. This arguably suffers from "looking under the lamp post", since NEAs are mostly discovered close to the opposition direction, so I also took the distribution of NEA orbits recently derived by Granvik and others and extracted, from a set of 100,000 synthetic orbits they provided, a subset of Earth-crossing PHAs and similarly adjusted them to be intersecting orbits. This should represent an unbiased set of orbits. I then weighted the impact directions by the individual Opik impact probability to obtain a distribution of impact directions weighted by actual impact probabilities. The result was that more than 40% of incoming trajectories clustered within 60 degrees of the opposition direction, and a similar fraction come from within 60 degrees of the solar direction. Thus ~80% of impactors come from only about 1/3 of the sky area, with almost none coming from 60-120 degrees solar elongation. The message is that existing ground-based surveys can hardly be improved upon by greater sky coverage with respect to detecting "death plunge" objects, and even space-based instruments offer very little improvement due to the very low solar elongation of most objects approaching from the solar direction.

    The Nuclear Energy Agency (NEA) within the Organization for Economic Cooperation and Development (OECD) ia an intergovernmental organization consisting of industrialized countries with shared democratic principles and free market economics. The objectives of the agency are to identify key issues related to nuclear energy and to address these issues as well as to implement joint R and D projects, contributing to the development of nuclear energy as a safe, environmentally-acceptable and economical energy source through cooperation among its participating countries. Appropriate measures to effectively implement international nuclear cooperation and strategies to upgrade Korea's status in the international arena as well as ways to utilize the agency for our benefits through analysis of its policy and current status of the agency as a multilateral nuclear cooperative body are also presented in this report. Analysis of information about the agency's activities and acquisition of capabilities to collect relevant information, coupled with efforts to enhance Korea's status in the international nuclear arena by actively being involved in the international organizations such as OECD/NEA are required to positively deal with rapid changes in the international nuclear arena and establish effective national nuclear policies. This report can be utilized as valuable material not only in establishing national nuclear policy by giving an overview of the report prepared by the high level advisory group on the future of the OECD Nuclear Energy Agency, who recently wrapped up their activities, but also in promoting the understanding of the agency's activities and the agency's long-term perspective mapped out in 1995.

    During the last three years a significant number of international activities have been undertaken on Primary Radiation Damage (PRD): the Expert Group on Primary Radiation Damage belonging to the Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems (WPMM- OECD/NEA/NSC), Coordinated Research Project (CRP) on “Primary Radiation Damage Cross Sections” (IAEA/NDS) and the activities of the European Consortium on Nuclear Data Development and Analysis for Fusion within the Fusion for Energy (F4E) Program. NEA activities related to fuels and structural materials are coordinated by the Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems, WPMM. In May 2015, the Expert Group on “Primary Radiation Damage” reviewed the limitation of the NRT-dpa standard, and recommended a new improved standard of primary damage characteristics, the arc-dpa. Recently, the new Expert Group on Structural Materials Modelling (SMM) has been created to enhance efforts on the multiscale modelling approach applied to structural materials, in order to investigate phenomena that can not be studied experimentally, predicting how the nanostructure and the microchemistry changes under irradiation

    2016-01-01

    The 6U (approx.10 cm x 20 cm x 30 cm) cubesat Near Earth Asteroid (NEA) Scout1, projected for launch in September 2018 aboard the maiden voyage of the Space Launch System, will utilize a solar sail as its main method of propulsion throughout its approx.3-year mission to a Near Earth Asteroid. Due to the extreme volume constraints levied onto the mission, an acutely compact solar sail deployment mechanism has been designed to meet the volume and mass constraints, as well as provide enough propulsive solar sail area and quality in order to achieve mission success. The design of such a compact system required the development of approximately half a dozen prototypes in order to identify unforeseen problems, advance solutions, and build confidence in the final design product. This paper focuses on the obstacles of developing a solar sail deployment mechanism for such an application and the lessons learned from a thorough development process. The lessons presented will have significant applications beyond the NEA Scout mission, such as the development of other deployable boom mechanisms and uses for gossamer-thin films in space.

    Six years after the Fukushima Daiichi nuclear power plant accident, the Japanese government and Tokyo Electric Power Holdings, Inc. (TEPCO) are shifting their focus to strategy planning for long-term challenges related to the decommissioning of the damaged reactors. The international community has been helping to address the unprecedented challenges of managing the accident facilities. The NEA is playing a key supporting and coordinating role in the international community, in particular in the area of radioactive waste management and the evaluation of the conditions and location of fuel debris. In the first half of 2017, a series of visual investigations using remotely controlled equipment and robots were performed to identify the condition of vessels inside, as well as the distribution of fuel debris in all three units. In the summer of 2017, as stated in the government road-map, policies for fuel debris retrieval from each unit would be presented, and would result in a discussion on which unit should be the first to undergo fuel debris retrieval in 2018. In addition, the basic policy for the processing and disposal of radioactive material arising from the accident would be conceptualised in the year 2017. This article highlights ongoing international joint activities within the NEA framework, corresponding to the challenges that have been identified in the Fukushima Daiichi decommissioning strategy planning

    The Thermochemical Database (TDB) Project was created three decades ago as a joint undertaking of the NEA Radioactive Waste Management Committee and the NEA Data Bank. The project involves the collection of high-quality and traceable thermochemical data for a set of elements (mainly minor actinides and fission products) relevant to geophysical modelling of deep geological repositories. Funding comes from 15 participating organisations, primarily national nuclear waste authorities and research institutions. The quantities that are stored in the TDB database are: the standard molar Gibbs energy and enthalpy of formation, the standard molar entropy and, when available, the heat capacity at constant pressure, together with their uncertainty intervals. Reaction data are also provided: equilibrium constant of reaction, molar Gibbs energy of reaction, molar enthalpy of reaction and molar entropy of reaction. Data assessment is carried out by teams of expert reviewers through an in-depth analysis of the available scientific literature, following strict guidelines defined by the NEA to ensure the accuracy and self-consistency of the adopted datasets. Thermochemical data that has been evaluated and selected over the years have been published in the 13 volumes of the Chemical Thermodynamics series. They are also stored in a database that is updated each time the study of a new element is completed. The TDB selected data are made available to external third parties through the NEA web site where data extracted from the database can be displayed and downloaded as plain text files. Following recent recommendations of the Task Force on the Future Programme of the NEA Data Bank to enhance scientific expertise and user services, a renewal of the software managing the TDB database is being undertaken. The software currently used was designed 20 years ago and is becoming obsolete. Redesigning the application will provide an opportunity to correct current shortcomings and to develop

    The Forum on Stakeholder Confidence (FSC) was established by the NEA Radioactive Waste Management Committee (RWMC) in the year 2000. It fosters learning about stakeholder dialogue and ways to develop shared confidence, informed consent and acceptance of radioactive waste (RW) management solutions. A 'stakeholder' is defined as anyone with a role to play or an interest in the process of deciding about RW management. The FSC provides a setting for direct stakeholder exchange in an atmosphere of mutual respect and learning. Participating in this forum are government policy and regulatory officials, R and D specialists, implementers, and industry representatives from NEA member countries. Together they analyse, document and provide recommendations on today's and tomorrow's processes for embedding waste management programs into a socio-political decision-making context. The FSC convenes annually for a regular meeting and is often complemented by an FSC national workshop. The regular meetings include lectures and topical case study sessions to share experiences. FSC national workshops are organised in volunteer NEA member countries to bring together all the national stakeholders to provide a neutral ground for discussion, dialogue and advancement of knowledge on long-term radioactive waste management. FSC members and other international actors involved in RW management are invited to learn about the host country's waste management program and provide support by giving an external reflection built up on their own experience. They are often supplemented by a half a day devoted to a community visit (potential or selected site for a repository) or open event (public meeting or debate). 2016 marked the 10. national workshop of the FSC which took place in Switzerland. It focused on 'Bridging Gaps - Developing Sustainable Inter-generational Decision-making in Radioactive Waste Management'. The workshop provided a forum for the participants from around the world to learn from

    Massara, Simone

    2014-01-01

    After the events at the Fukushima Daiichi nuclear power plant in March 2011, enhancing the accident tolerance of light water reactors (LWRs) became a topic of serious discussion. One outcome of those discussions has been to promote research into the development of advanced fuels and more robust reactor system technologies with improved performance, reliability and safety characteristics during normal operations and under accident conditions. The Fukushima Daiichi accident has highlighted in particular the importance of reducing hydrogen production rates and increasing fission product retention during extended loss of cooling accidents. In this context, the NEA organised two international workshops to share information and discuss technical and safety issues associated with the development of accident-tolerant fuels (ATFs) for LWRs. Presentations were given by experts from various organisations, industry and regulatory bodies of NEA member countries, as well as from representatives of international bodies. The presentations focused on lessons learnt from the Fukushima Daiichi accident, the desired characteristics of ATFs, potential design options and candidate materials, as well as the current state of the art in related modelling and simulation methods. During discussions following these workshop presentations, delegates agreed to establish a collaborative framework on ATFs within the NEA. Reporting to the Nuclear Science Committee, the Expert Group on Accident-tolerant Fuels for Light Water Reactors (EGATFL) will define and carry out a programme of work to help advance the scientific knowledge needed to provide the technical underpinning for the development of advanced LWR fuels with more enhanced accident tolerance compared to currently used zircaloy/UO 2 fuels. The group will foster information exchange on material properties and relevant phenomenological experiments, carry out state-of-the-art reviews, organise benchmark studies and foster international

  15. Improving nuclear regulation. Compilation of Nea regulatory guidance booklets

    International Nuclear Information System (INIS)

    2009-01-01

    A common theme throughout the series of NEA regulatory guidance reports, or 'green booklets', is the premise that the fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear facilities are operated at all times and later decommissioned in an acceptably safe manner. In meeting this objective the regulator must keep in mind that it is the operator that has responsibility for safely operating a nuclear facility; the role of the regulator is to oversee the operator's activities as related to assuming that responsibility. For the first time, the full series of these reports have been brought together in one edition. As such, it is intended to serve as a knowledge management tool both for current regulators and the younger generation of nuclear experts entering the regulatory field. While the audience for this publication is primarily nuclear regulators, the information and ideas may also be of interest to nuclear operators, other nuclear industry organisations and the general public.

  2. Review of fast reactor activities at OECD (NEA), March 1979

    1979-07-01

    In February 1978, OECD(NEA) published an expert group report on 'Nuclear Fuel Cycle Requirements and Supply Considerations, Through the Long Term'. In publishing this report, the Agency sought to fulfil three objectives. First, as a source of data on uranium and fuel cycle services, the report identified future imbalances between supply and demand, and possible areas for international cooperation in the resolution of such problems. Secondly, in examining several alternative nuclear power scenarios through the long term (defined as the year 2025), it showed the comparative needs of advanced reactors for uranium and for supporting services, thereby establishing the basis for further development of uranium resources and specific reactor systems. Finally, as a comprehensive data source, it should provide assistance to those having responsibilities in planning, forecasting, and programme management in areas relating to the fuel cycle. An analysis of alternative reactor strategies in the longer term makes it clear that continued reliance on thermal converters in this period will result in rapid depletion of known uranium resources. Even with dramatic increases in known resources, nuclear power would be able to play only a temporary role in satisfying world energy needs. The use of advanced near-breeders (including those which utilise thorium) can do much to reduce the total rate of depletion of uranium resources, but their requirements will still result in eventual depletion of known resources. On the other hand, breeder reactors would provide a virtually inexhaustible source of energy supply within foreseeable extensions of known uranium resources. In fact, the introduction of breeders in the longer term could, by the year 2025, reduce annual requirements for uranium at or below levels for the year 2000. By the year 2025, the cumulative uranium requirements of the breeder can have reached a plateau, while the cumulative requirements of other reactor strategies would

    The OECD Nuclear Energy Agency has a long tradition of expertise in the area of nuclear emergency policy, planning, preparedness and management. Through its activities in this field, the Agency offers its member countries unbiased assistance on nuclear preparedness matters, with a view to facilitating improvements in nuclear emergency preparedness strategies and response at the international level. The 1986 Chernobyl accident demonstrated that nuclear accidents can have international consequences, highlighting the need for international co-operation, and leading to improvements in the areas of international communication, information exchange and harmonization of response actions between countries. From its inception, the NEA Working Party on Nuclear Emergency Matters has focused on improving the effectiveness of international nuclear emergency preparedness and management. Part of its work programme is set on exploring and developing new concepts and future procedures to enhance national and international preparedness and response management. A central approach to this has been the preparation and conduct of the International Nuclear Emergency Exercise (INEX) series. The role and strategies of exercises and future directions are discussed in this presentation. (A.L.B.)

    The increasing use of nuclear power and public interest in the safety controls led to the proposal by the sub-Committe on Licensing of the NEA Committee on the Safety of Nuclear Installations for a specialist meeting on regulatory inspection practices. This report which was prepared at the request of the sub-Committee to assist in the exchange of views and experience at the meeting reviews the response to a questionnaire on the systems employed, the scope and objectives and the effort involved in regulatory inspection throughout all stages of the life of a nuclear power plant. Other aspects of regulatory inspection activities are discussed including documentation, procedures for changes in technical specification and modifications to plant, powers and duties of regulatory inspection personnel and actions to be taken in the event of an accident or emergency. The report concludes with some comments on those aspects of regulatory inspection practices where further information and an exchange of experience might prove to be beneficial to Member countries.

    1978-01-01

    Based on the replies to a questionnaire, this report gives a description and comparative evaluation of the regulatory inspection activities in several NEA Member countries. The questionnaire which was circulated to all Member countries requested details on the organisation, system, scope and objectives of nuclear regulatory inspection and the effort required throughout all stages of the life of a nuclear plant including the use of independent bodies or consultants. Additional information was requested on the documentation concerned with regulatory inspections, incident and accident reporting procedures, and the duties, powers and bases for recruitment of regulatory personnel with the object of covering all related aspects. However, because of the differences in national practices and perhaps in the interpretation of the questionnaire, it proved to be extremely difficult to make an evaluation and comparison of inspection activities and effort involved in these Member countries. This report, which includes a section on the nuclear power programme in Member countries, should therefore only be regarded as an initial review but it provides a useful contribution to the exchange of experience and views on regulatory inspection practices

    Under the guidance of the OECD-NEA Nuclear Science Committee, the expert group acts as a forum for scientific and technical information exchange on advanced light water reactor (LWR) fuels with enhanced accident tolerance. The expert group focusses on the fundamental properties and behaviour under normal operations and accident conditions for advanced core materials and components (fuels, cladding, control rods, etc.). The materials considered are applicable to Gen II and Gen III Light Water Reactors, as well as Gen III+ reactors under construction. The objective of the expert group is to define and coordinate a programme of work to help advance the scientific knowledge needed to provide the technical underpinning for the development of advanced LWR fuels with enhanced accident tolerance compared to currently used zircaloy/UO 2 fuel systems, as well as other non-fuel core components with important roles in LWR performance under accident conditions.

    Highlights: • A benchmark exercise on stratification erosion in containment was conducted using a test in the PANDA facility. • Blind calculations were provided by nineteen participants. • Results were compared with experimental data. • A ranking was made. • A large spread of results was observed, with very few simulations providing accurate results for the most important variables, though not for velocities. - Abstract: The third International Benchmark Exercise (IBE-3) conducted under the auspices of OECD/NEA is based on the comparison of blind CFD simulations with experimental data addressing the erosion of a stratified layer by an off-axis buoyant jet in a large vessel. The numerical benchmark exercise is based on a dedicated experiment in the PANDA facility conducted at the Paul Scherrer Institut (PSI) in Switzerland, using only one vessel. The use of non-prototypical fluids (i.e. helium as simulant for hydrogen, and air as simulant for steam), and the consequent absence of the complex physical effects produced by steam condensation enhanced the suitability of the data for CFD validation purposes. The test started with a helium–air layer at the top of the vessel and air in the lower part. The helium-rich layer was gradually eroded by a low-momentum air/helium jet emerging at a lower elevation. Blind calculation results were submitted by nineteen participants, and the calculation results have been compared with the PANDA data. This report, adopting the format of the reports for the two previous exercises, includes a ranking of the contributions, where the largest weight is given to the time progression of the erosion of the helium-rich layer. In accordance with the limited scope of the benchmark exercise, this report is more a collection of comparisons between calculated results and data than a synthesis. Therefore, the few conclusions are based on the mere observation of the agreement of the various submissions with the test result, and do not

    and benchmark data. The numerical scheme has a very small scheme diffusion and is the second and the first order accurate in space and time, correspondingly. We compare and contrast simulation results for three computational fluid dynamics codes CABARET, Conv3D, and Nek5000 for the T-junction thermal striping problem that was the focus of a recent OECD/NEA blind benchmark. The corresponding codes utilize finite-difference implicit large eddy simulation (ILES), finite-volume LES on fully staggered grids, and an LES spectral element method (SEM), respectively. The simulations results are in a good agreement with experimenatl data. We present results from a study of sensitivity to computational mesh and time integration interval, and discuss the next steps in the simulation of this problem.

  2. Near Earth Asteroid Scout: NASA's Solar Sail Mission to a NEA

    2017-01-01

    NASA is developing a solar sail propulsion system for use on the Near Earth Asteroid (NEA) Scout reconnaissance mission and laying the groundwork for their use in future deep space science and exploration missions. Solar sails use sunlight to propel vehicles through space by reflecting solar photons from a large, mirror-like sail made of a lightweight, highly reflective material. This continuous photon pressure provides propellantless thrust, allowing for very high Delta V maneuvers on long-duration, deep space exploration. Since reflected light produces thrust, solar sails require no onboard propellant. The Near Earth Asteroid (NEA) Scout mission, funded by NASA's Advanced Exploration Systems Program and managed by NASA MSFC, will use the sail as primary propulsion allowing it to survey and image Asteroid 1991VG and, potentially, other NEA's of interest for possible future human exploration. NEA Scout uses a 6U cubesat (to be provided by NASA's Jet Propulsion Laboratory), an 86 m(exp. 2) solar sail and will weigh less than 12 kilograms. NEA Scout will be launched on the first flight of the Space Launch System in 2018. The solar sail for NEA Scout will be based on the technology developed and flown by the NASA NanoSail-D and The Planetary Society's Lightsail-A. Four approximately 7 m stainless steel booms wrapped on two spools (two overlapping booms per spool) will be motor deployed and pull the sail from its stowed volume. The sail material is an aluminized polyimide approximately 2.5 microns thick. As the technology matures, solar sails will increasingly be used to enable science and exploration missions that are currently impossible or prohibitively expensive using traditional chemical and electric propulsion systems. This paper will summarize the status of the NEA Scout mission and solar sail technology in general.

    The Working Group on Fuel Safety (WGFS) is part of the Committee on the Safety of Nuclear Installations (CSNI) of the Nuclear Energy Agency and has the main mission of advancing the current understanding and addressing fuel safety issues. Recent and current activities of the working group have addressed mainly the loss of coolant accident (LOCA), the reactivity initiated accident (RIA), the fuel safety criteria and leaking fuel issues, as well as Fukushima-related fuel topics. In the area of LOCA, the group issued different documents, the most notable being a very comprehensive state of the art report [NEA/CSNI/R (2009)15]. Regarding RIA, some documents were finalised and issued in the recent years, as well as a state of the art report [NEA/CSNI/R (2010)1]. The question of leaking fuel and how it is handled in the reactors is an activity that is just starting. Of particular interest to people developing new fuel concepts is the Nuclear Fuel Safety Criteria Technical Review - Second Edition [NEA/CSNI/R (2012)3]. This document provides a broad overview of the numerous criteria used in the NEA member countries to demonstrate to safe use of fuel in light water reactors. The WGFS has started discussions about fuel related issues raised by the Fukushima accident, in particular, hydrogen production. New concepts have been proposed to solve these issues but it appears that these concepts will need to go through a long qualification process to assess their adequacy for the different situations considered in the evaluation of fuel safety, from normal operation to accident conditions

  4. The role of the NEA incident reporting system in trend and pattern studies

    1990-01-01

    When the Incident Reporting System of the OECD Nuclear Energy Agency (NEA-IRS) was first instituted in 1980, Members recognized the fact that since the data thus collected only pertains to significant safety-related incidents, the system cannot be used for in-depth statistical analyses. Rather, the NEA-IRS is best suited, in addition to single event assessments, to studies that provide indications related to system, component or human performance; these indications could also initiate trend analyses on more complete data bases. Examples are the generic studies on the Loss of Containment Functions (completed last year) and the Loss of Residual Heat Removal (due for completion this year), and the studies related to the human factor. Another type of use of the IRS data was started last year by the NEA Principal Working Group 1 on Operating Experience and Human Factors (PWG 1) in response to the encouragement of the OECD/NEA Committee on the Safety of Nuclear Installations (CSNI), to make the best use of Operating Experience, notably of information disseminated through the NEA-IRS. These applications consisted of scanning the IRS data base for events that could be of interest to specialized domains such as radiation protection, fracture mechanics and fire protection. In the paragraphs which follow, some highlights of the results of these scans are presented (reference is made at the end of this paper to the reports detailing the results of these applications)

    The NEA TDB Project aims at making available a comprehensive, internally consistent and quality-assured chemical thermodynamic database of selected chemical elements in order to meet the specialized modelling requirements for safety assessments of radioactive waste disposal systems. The project was initiated by the NEA in 1984 and reorganized in 1998. During the period 1984-1998 (TDB Project Phase I, TDB-I), reviews on the chemical thermodynamics for the following elements were completed: U, Am and Tc. A further review originating from TDB-I and dealing with data for Np and Pu appeared in print in May 2001. Although not strictly a part of TDB-I, a further collective publication of OECD/NEA [5] is a much-cited reference in the field of aquatic chemistry. The second phase of the TDB Project (TDB Project Phase II, TDB-II) was started in 1998 following an agreement between the following Participating Organisations. (author)

    The nuclear atomic association NEA of the OECD, to which 23 western industrial countries belong to, was established 25 years ago (1959) as ''Nuclear Energy Agency'', almost simultaneously with other large international nuclear energy organisations. The NEA undertook special tasks during the international cooperation, which have shifted over time. A special feature today is the cooperation by means of international committees, which are supported by a small own staff of the organisation. The focus points lie within the area of safety and regimentation and on chosen scientific and technical studies.

    To assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes, the NEA serves as a forum for sharing and analysing information and experience among its member countries in order to pool and maintain their technical expertise and human infrastructure and to support nuclear activities by providing them with nuclear policy analyses. Comprehensive and effective legal regimes are necessary to help achieve confidence in the peaceful use of nuclear energy. These regimes, whose goals are to protect the public and the natural environment from the risks inherent in such activities, include regulation at a national level, co-operation at bilateral and multilateral levels and international harmonisation of national policies and legislation through adherence to international conventions. Regimes need to be strong enough to set and enforce limits, and flexible enough to keep pace with technological advances and changing public concerns. The NEA collects, analyses and disseminates information on nuclear law in general and on topical nuclear legal issues in particular. Nuclear law is the body of special legal norms created to regulate the conduct of legal or natural persons engaged in activities related to fissionable materials, ionising radiation and exposure to natural sources of radiation. In 1995, the NEA began publishing country profiles entitled Nuclear Legislation in OECD and NEA Countries - Regulatory and Institutional Frameworks for Nuclear Activities or the 'Grand Orange', a name which was adopted and became widely used because of the colour of the initial cover. Since 2006, these country profiles can be downloaded free online both in English and French from the NEA web site. The NEA endeavours to complement country profiles by publishing online an English, non

    Full Text Available La citarabina es un antimetabolito utilizado en el tratamiento de las leucemias agudas mieloides (LAM. Esta droga presenta numerosos efectos adversos (mielosupresión, toxicidad en sistema nervioso central, hepática, gastrointestinal, ocular y cutánea. La toxicidad dermatológica es habitualmente descrita como rara, sin embargo existen diferencias en la incidencia comunicada. Se realizó un estudio retrospectivo donde se incluyeron todas las LAM tratadas con quimioterapia que incluía citarabina, entre el 1º de julio 2006 y el 1° de julio 2012. Se incluyeron 46 pacientes con una mediana de edad de 55 años. La incidencia global de reacciones cutáneas fue de 39% (n = 18. La presencia de lesiones cutáneas no se asoció con sexo, edad, antecedentes de atopía, de reacciones medicamentosas, tipo de LAM ni dosis de citarabina utilizada. Las lesiones se observaron entre 2 a 8 días de iniciado el tratamiento. En cuanto al grado lesional, 27.8% presentaron grado 1, 38.9% grado 2 y 33.3% grado 3. No existieron lesiones grado 4 ni muerte vinculada a toxicidad cutánea. En cuanto al tipo de lesiones, 55.6% se presentaban con máculas, 22.2% con pápulas y 22.2% con eritema. Con respecto a la distribución de las lesiones, 52% de los pacientes presentaron una distribución difusa, 39.3% acral y 8.7% a nivel flexural. Las reacciones adversas cutáneas con la administración de citarabina son frecuentes en nuestro medio, en algunos casos con afectación grave. Si bien suelen resolverse espontáneamente, pueden determinar mayor riesgo de infección, así como comprometer la calidad de vida.

    Full Text Available Como el trazo esencial que da figura y origen a lo existente, desde sus orígenes míticos hasta los razonamientos científicos y desde el diario transcurrir hasta las formas estéticas que de ella se derivan, la línea es el elemento constitutivo que proporciona sentido, horizonte y razón al conocimiento y al sentir humano. Los múltiples problemas que se originan en el contexto que rodea un hecho cotidiano, un experimento o una reflexión filosófica, un acto de fe o un asunto pedagógico, suscitan un planteamiento de propuestas y proyectos. La construcción y la reconstrucción de éstos, el esbozo metodológico, los procesos y los productos investigativos, su socialización y difusión tienen una raíz esencial: la línea que los origina. A partir del mito y la narrativa se consigue vislumbrar la génesis de la línea y su armazón determinante en el progreso del conocimiento, la docencia y la investigación. Se puede decir, merced a lo investigado, que se mantiene un descuido epistemológico en la explicación de la línea de conocimiento o de investigación que debe ser subsanado yendo a sus orígenes y visualizando su prospectiva, pues la línea constituye un referente imprescindible y estructural de cualquier proceso investigativo.

  3. NEA's analysis of the needs in innovation and research in the domain of dismantling

    International Nuclear Information System (INIS)

    Laurent, G.

    2014-01-01

    Today's approach of the dismantling of nuclear facilities is labour intensive and consequently very expensive. NEA's study suggests that research works should be done to find more efficient technologies for decontamination and dismantling. 5 lines of research have been identified by NEA. First, new technologies must be found to get a more accurate spatial distribution of contaminants. Secondly, the different cutting methods must be assessed in terms of efficiency, dosimetry and secondary waste generation. Thirdly, a better understanding of the chemical and physical processes that may be used for the decontamination of metals, concretes, underground water and soil. Fourthly, the management of radioactive waste implies to know the interaction between wastes and packages over a very long period. Fifthly, an accurate characterization of a complex site housing various contaminating sources and different hydro-geological conditions implies the development of 3-dimensional radiation transport codes and the use of innovative means like satellite monitoring.

    Several OECD Member Countries have agreed to establish the OECD/NEA 'Component Operational Experience, Degradation & Ageing Programme' (CODAP) to encourage multilateral co-operation in the collection and analysis of data relating to degradation and failure of metallic piping and non-piping metallic passive components in commercial nuclear power plants. The scope of the data collection includes service-induced wall thinning, part through-wall cracks, through-wall cracks with and without active leakage, and instances of significant degradation of metallic passive components, including piping pressure boundary integrity. The OECD/NEA Committee on the Safety of Nuclear Installations (CSNI) acts as an umbrella committee of the Project. CODAP is the continuation of the 2002-2011 'OECD/NEA Pipe Failure Data Exchange Project' (OPDE) and the Stress Corrosion Cracking Working Group of the 2006-2010 'OECD/NEA SCC and Cable Ageing project' (SCAP). OPDE was formally launched in May 2002. Upon completion of the 3rd Term (May 2011), the OPDE project was officially closed to be succeeded by CODAP. SCAP was enabled by a voluntary contribution from Japan. It was formally launched in June 2006 and officially closed with an international workshop held in Tokyo in May 2010. Majority of the Member Organizations of the two projects were the same, often being represented by the same person. In May 2011, thirteen countries signed the CODAP 1st Term agreement (Canada, Chinese Taipei, Czech Republic, Finland, France, Germany, Korea (Republic of), Japan, Slovak Republic, Spain, Sweden, Switzerland and United States of America). The 1st Term (2011-2014) work plan includes the preparation of Topical Reports to foster technical cooperation and to deepen the understanding of national differences in ageing management.

    2015-01-01

    The goal of the OECD Nuclear Energy Agency (NEA) in the area of nuclear science is to help member countries identify, collate, develop and disseminate the basic scientific and technical knowledge required to ensure safe and reliable operation of current nuclear systems and to develop next generation technologies. Within these general goals, the current nuclear science programme has three key objectives: (i) to help advance the existing scientific knowledge needed to enhance the performance and safety of current nuclear systems, (ii) to contribute to building a solid scientific and technical basis for the development of future generation nuclear systems and (iii) to support the preservation of essential knowledge in the field of nuclear science. As part of the second and third of these objectives, an extensive programme of work to preserve and evaluate data from integral experiments has been established, including reactor physics, shielding and criticality safety experiments on fast reactor systems. Data from experimental facilities are reviewed and, if necessary, archives of information are made safe. This may typically involve the indexing and scanning of key documents and archiving of logbooks, for example. Selected experiments go through a detailed evaluation process and where deemed appropriate, a benchmark description is created in a standardized format for inclusion in one of the NEA Data Bank international databases. This information is used extensively by the international nuclear science community to validate their modelling and simulation tools. The process can be viewed as part of a broader knowledge management function, where information is gathered, evaluated, linked and made accessible to a wide range of users. The presentation gives details of the main databases maintained and developed by the NEA, focusing on those related to fast reactor applications. The status of recent preservation activities for fast reactor archives in the United Kingdom is

    The present report summarises the NEA workshop proceedings. Chapter 1 recalls the setting in which the 2017 workshop was organised, the development of the workshop and the audience it gathered. Subsequent chapters are based on rapporteurs' accounts of the plenary and keynote talks (Chapter 2) and topical presentations (Chapter 3), as well as the dialogues among attendees which were then reported in plenary (Chapter 4). Quotes highlighted throughout the report were drawn from speakers' material or from the dialogues. In this way the publication reports the kaleidoscope of views and practices brought by NEA member countries and their experts from almost all nuclear areas as well as from some other energy technology sectors. It documents best practice and lessons learnt. Furthermore, Chapter 5 singles out the commonalities and differences found across the countries and sectors, as well as tangible take-away from the workshop. The reader will find that certain major messages are repeated in different parts of the report, as a sign of the convergence between different contexts, experts, sessions and discussions. Chapter 6 reports the attendees' evaluation of the workshop and the actions requested to progress. The annexes provide further resources: other NEA publications of interest; instructions for facilitating dialogue; and the list of participants

    Full Text Available A comunidade é um dos conceitos de maior importância, desde o nascimento da Sociologia. Sua relevância permanece tal que o debate em torno de sua definição é contínuo, adentrando a teoria social contemporânea. Recorrente nesse debate é a dicotomia entre comunidade e sociedade e entre a forma de vida tradicional e a moderna. Neste artigo, debatem-se algumas das principais teorizações clássicas e contemporâneas sobre a ideia de comunidade, enfocando principalmente as teorias que contrapõem as relações sociais comunitárias e a individualização característica da vida moderna. Entre os “clássicos” da Sociologia, optou-se por debater as teorias de Émile Durkheim e Ferdinand Tönnies, e, entre as teorias contemporâneas, optou-se pelas de Michel Maffesoli e Zygmunt Bauman. O objetivo aqui é demarcar divergências e similitudes entre suas diferentes abordagens.

  19. Manual for IRS Coding. Joint IAEA/NEA International Reporting System for Operating Experience

    International Nuclear Information System (INIS)

    2011-01-01

    The International Reporting System for Operating Experience (IRS) is jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA). In early 2010, the IAEA and OECD/NEA jointly issued the IRS Guidelines, which described the reporting system and process and gave users the necessary elements to enable them to produce IRS reports to a high standard of quality while retaining the effectiveness of the system expected by all Member States operating nuclear power plants. The purpose of the present Manual for IRS Coding is to provide supplementary guidance specifically on the coding element of IRS reports to ensure uniform coding of events that are reported through IRS. This Coding Manual does not supersede the IRS Guidelines, but rather, supports users and preparers in achieving a consistent and high level of quality in their IRS reports. Consistency and high quality in the IRS reports allow stakeholders to search and retrieve specific event information with ease. In addition, well-structured reports also enhance the efficient management of the IRS database. This Coding Manual will give specific guidance on the application of each section of the IRS codes, with examples where necessary, of when and how these codes are to be applied. As this reporting system is owned by the Member States, this manual has been developed and approved by the IRS National Coordinators with the assistance of the IAEA and NEA secretariats

Sua clínica é de dor na parte anterior do quadril que piora à extensão, abdução e rotação interna do mesmo. O diagnóstico é confirmado pelo ultrassom ou ressonância nuclear magnética do quadril. A bursite iliopectínea responde bem ao tratamento conservador com anti-inflamatório não hormonal e repouso. Devido a esta boa evolução, não raro, pode-se tratar uma bursite iliopectínea com sucesso sem se saber o que está tratando.Although there are not many reports in literature, iliopectineal bursitis presents clinically with signs and symptoms frequently found in outpatient services and practice. Its clinical presentation is anterior hip pain that worsens with the extension, abduction and internal rotation of the hip. The diagnosis is confirmed by ultrasound or magnetic nuclear resonance imaging of the hip. The iliopectineal bursitis responds well to conservative treatment with non-hormonal anti-inflammatory drugs and rest. Due to its good evolution, it is not rare to treat iliopectineal bursitis successfully without even knowing what is being treated.

    2001-01-01

    This article summarizes activities of the OECD/NEA Burnup Credit Expert Panel, a subordinate group to the Working Party on Nuclear Criticality Safety (WPNCS). The WPNCS of the OECD/NEA coordinates and carries out work in the domain of criticality safety at the international level. Particular attention is devoted to establishing sound databases required in this area and to addressing issues of high relevance such as burnup credit. The activities of the expert panel are aimed toward improving safety and identifying economic solutions to issues concerning the back-end of the fuel cycle. The main objective of the activities of the OECD/NEA Burnup Credit Expert Panel is to demonstrate that the available criticality safety calculational tools are appropriate for application to burned fuel systems and that a reasonable safety margin can be established. The method established by the expert panel for investigating the physics and predictability of burnup credit is based on the specification and comparison of calculational benchmark problems. A wide range of fuel types, including PWR, BWR, MOX, and VVER fuels, has been or are being addressed by the expert panel. The objective and status of each of these benchmark problems is reviewed in this article. It is important to note that the focus of the expert panel is the comparison of the results submitted by each participant to assess the capability of commonly used code systems, not to quantify the physical phenomena investigated in the comparisons or to make recommendations for licensing action.

  6. The Fukushima Daiichi Nuclear Power Plant Accident: OECD/NEA Nuclear Safety Response and Lessons Learnt

    International Nuclear Information System (INIS)

    2013-01-01

    Following the March 2011 accident at the Fukushima Daiichi nuclear power plant, all NEA member countries took early action to ensure and confirm the continued safety of their nuclear power plants and the protection of the public. After these preliminary safety reviews, all countries with nuclear facilities carried out comprehensive safety reviews, often referred to as 'stress tests', which reassessed safety margins of nuclear facilities with a primary focus on challenges related to conditions experienced at the Fukushima Daiichi nuclear power plant, for example extreme external events and the loss of safety functions, or capabilities to cope with severe accidents. As appropriate, improvements are being made to safety and emergency response systems to ensure that nuclear power plants are capable of withstanding events that lead to loss of electrical power and/or cooling capability. In the weeks following the accident, the NEA immediately began establishing expert groups in the nuclear safety and radiological protection areas, as well as contributing to information exchange with the Japanese authorities and other international organisations. It promptly provided a forum for high-level decision makers and regulators within the G8-G20 frameworks. The NEA actions taken at the international level in response to the accident have been carried out primarily by the three NEA standing technical committees concerned with nuclear and radiation safety issues - the Committee on Nuclear Regulatory Activities (CNRA), the Committee on the Safety of Nuclear Installations (CSNI) and the Committee on Radiation Protection and Public Health (CRPPH) - under the leadership of the CNRA. More than two years following the accident, the NEA continues to assist the Japanese authorities in dealing with their nuclear safety and recovery efforts as well as to facilitate international co-operation on nuclear safety and radiological protection matters. It is strongly supporting the establishment of

  8. NEAs: Phase Angle Dependence of Asteroid Class and Diameter from Observational Studies

    We will discuss the results of a planned observation campaign of Near Earth Asteroids (NEAs), 1999 CU3, 2002 GM2, 2002 FG7, and 3691 Bede with instruments on the United Kingdom Infrared Telescope (UKIRT) from 15-Mar-2015 to 28-April 2015 UT. We will study the phase-angle dependence of the reflectance and thermal emission spectra. Recent publications reveal that the assignment of the asteroid class from visible and near-IR spectroscopy can change with phase angle for NEAs with silicate-bearing minerals on their surfaces (S-class asteroids) (Thomas et al. 2014, Icarus 228, 217; Sanchez et al. 2012 Icarus 220, 36). Only three of the larger NEAs have been measured at a dozen phase angles and the trends are not all the same, so there is not yet enough information to create a phase-angle correction. Also, the phase angle effect is not characterized well for the thermal emission including determination of the albedo and the thermal emission. The few NEAs were selected for our study amongst many possible targets based on being able to observe them through a wide range of phase angles, ranging from less than about 10 degrees to greater than 45 degrees over the constrained date range. The orbits of NEAs often generate short observing windows at phase angles higher than 45 deg (i.e., whizzing by Earth and/or close to dawn or dusk). Ultimately, lowering the uncertainty of the translation of asteroid class to meteorite analog and of albedo and size determinations are amongst our science goals. On a few specific nights, we plan to observe the 0.75-2.5 micron spectra with IRTF+SpeX for comparison with UKIRT data including 5-20 micron with UKIRT+UIST/Michelle to determine as best as possible the albedos. To ensure correct phasing of spectroscopic data, we augment with TRAPPIST-telescope light curves and R-band guider image data. Our observations will contribute to understanding single epoch mid-IR and near-IR measurements to obtain albedo, size and IR beaming parameters (the

  9. Lessons for Interstellar Travel from the G&C Design of the NEA Scout Solar Sail Mission

    Science.gov (United States)

    Heaton, Andrew; Diedrich, Benjamin

    2017-01-01

    NASA is developing the Near Earth Asteroid (NEA) Scout mission that will use a solar sail to travel to an asteroid where it will perform a slow flyby to acquire science imagery. A guidance and control system was developed to meet the science and trajectory requirements. The NEA Scout design process can be applied to an interstellar or precursor mission that uses a beam-propelled sail. The scientific objectives are met by accurately targeting the destination trajectory position and velocity. The destination is targeted by understanding the force on the sail from the beam (or sunlight in the case of NEA Scout) over the duration of the thrust maneuver. The propulsive maneuver is maintained by accurate understanding of the torque on the sail, which is a function of sail shape, optical properties, and mass properties, all of which apply to NEA Scout and beam propelled sails. NEA Scout uses active control of the sail attitude while trimming the solar torque, which could be used on a beamed propulsion sail if necessary. The biggest difference is that NEA Scout can correct for uncertainties in sail thrust modeling, spacecraft orbit, and target orbit throughout the flight to the target, while beamed propulsion needs accurate operation for the short duration of the beamed propulsion maneuver, making accurate understanding of the sail thrust and orbits much more critical.

    2008-01-01

    The NEA Committee on the Safety of Nuclear Installations (CSNI) has recently completed a study on the availability and utilisation of facilities supporting safety studies for current and advanced nuclear power reactors. The study showed that significant steps had been undertaken in the past several years in support of safety test facilities, mainly by conducting multinational joint projects centered on the capability of unique test facilities worldwide. Given the positive experience of the safety research projects, it has been recommended that efforts be made to prioritize technical issues associated with advanced (Generation IV) reactor designs and to develop options on how to efficiently obtain the necessary data through internationally co-ordinated research, preparing a gradual extension of safety research beyond the needs set by currently operating reactors. This statement constitutes a reference for future CSNI activities and for safety authorities, R and D centres and industry for internationally co-ordinated research initiatives in the nuclear safety research area.

    The OECD Nuclear Energy Agency (NEA) started dealing with criticality-safety related subjects back in the seventies. In the mid-nineties, several activities related to criticality-safety were grouped together into the Working Party on Nuclear Criticality Safety. This working party has since been operating and reporting to the Nuclear Science Committee. Six expert groups co-ordinate various activities ranging from experimental evaluations to code and data inter-comparisons for the study of static and transient criticality behaviours. The paper describes current activities performed in this framework and the achievements of the various expert groups. (author)

    1998-01-01

    The OECD/NEA Data Bank collects, tests and distributes computer programs and numerical data in the field of nuclear energy applications. This activity is coordinated with several similar centres in the United States (ESTSC, NNDC, RSIC) and outside the OECD area through an arrangement with the IAEA. This information is shared worldwide for the benefit of scientists and engineers working on the safe and economic use of nuclear energy. The OECD/NEA Nuclear Science Committee the supervising body of the Data Bank has conducted a series of international computer code benchmark exercises with the aim of verifying the correctness of codes, of building confidence in models used for predicting macroscopic behaviour of nuclear systems and to drive towards refinement of models where necessary. Exercises involving nuclear cross section predictions, in-core reactor physics issues, such as pin cells for different type of reactors, plutonium recycling, reconstruction of pin power within assemblies, core transients, reactor shielding and dosimetry, away from reactor issues such as criticality safety for transport and storage of spent fuel, shielding of radioactive material packages and other problems connected with the back end of the fuel cycle, are listed and the relevant references provided.

    Conclusions: Progress to date: • Extensive programme of work to preserve and evaluate data from integral experiments has been established since the mid 1990s. • NEA Data Bank maintains and distributes several databases of these integral experiments, notably through the ICSBEP and IRPhE projects. • More recently programmes of work have been established to help preserve data from the UK Fast Reactor Programme and from various experiments related to minor actinide management. • Data obtained from these programmes are made available to the nuclear science community to provide high quality benchmarks against which modelling methods can be validated. • Involvement of younger scientists and engineers to work alongside well-established experts in the process of evaluating the information is a highly efficient means of transmitting tacit knowledge to the new generation of nuclear specialists. Conclusions: Looking ahead - • Further development of Databases and Database tools, e.g. – improved coverage of fast reactor experiments, MAs; – improved treatment of correlations in uncertainties between experiments; – production of sensitivities to facilitate identification of similar experiments. • Continuation securing UK archives and creating framework for information: – Start identifying suitable integral experiments for inclusion in NEA databases

  3. Theoretical study for heterojunction surface of NEA GaN photocathode dispensed with Cs activation

    2016-09-01

    For the disadvantages of conventional negative electron affinity (NEA) GaN photocathodes activated by Cs or Cs/O, new-type NEA GaN photocathodes with heterojunction surface dispensed with Cs activation are investigated based on first-principle study with density functional theory. Through the growth of an ultrathin n-type GaN cap layer on p-type GaN emission layer, a p-n heterojunction is formed on the surface. According to the calculation results, it is found that Si atoms tend to replace Ga atoms to result in an n-type doped cap layer which contributes to the decreasing of work function. After the growth of n-type GaN cap layer, the atom structure near the p-type emission layer is changed while that away from the surface has no obvious variations. By analyzing the E-Mulliken charge distribution of emission surface with and without cap layer, it is found that the positive charge of Ga and Mg atoms in the emission layer decrease caused by the cap layer, while the negative charge of N atom increases. The conduction band moves downwards after the growth of cap layer. Si atom produces donor levels around the valence band maximum. The absorption coefficient of GaN emission layer decreases and the reflectivity increases caused by n-type GaN cap layer.

    Highlights: • A time-dependent homogenization-free neutron transport benchmark was created. • The first phase, known as the kinetics phase, was described in this work. • Preliminary results for selected 2-D transient exercises were presented. - Abstract: A Nuclear Energy Agency (NEA), Organization for Economic Co-operation and Development (OECD) benchmark for the time-dependent neutron transport calculations without spatial homogenization has been established in order to facilitate the development and assessment of numerical methods for solving the space-time neutron kinetics equations. The benchmark has been named the OECD/NEA C5G7-TD benchmark, and later extended with three consecutive phases each corresponding to one modelling stage of the multi-physics transient analysis of the nuclear reactor core. This paper provides a detailed introduction of the benchmark specification of Phase I, known as the “kinetics phase”, including the geometry description, supporting neutron transport data, transient scenarios in both two-dimensional (2-D) and three-dimensional (3-D) configurations, as well as the expected output parameters from the participants. Also presented are the preliminary results for the initial state 2-D core and selected transient exercises that have been obtained using the Monte Carlo method and the Surface Harmonic Method (SHM), respectively.

  5. A strategic view on nuclear data needs. Report by the NEA Secretariat

    International Nuclear Information System (INIS)

    1993-09-01

    At its third meeting in October 1992, the NEA Nuclear Science Committee (NSC) discussed an interim report from a Working Party on scientific data requirements for the 1990s. Discussions covered: - the need for more accurate or new scientific nuclear data, - the continuing availability of data measurement facilities, - the risk of losing expertise with the retirement of experienced scientists, the role of national and international data centres. It was agreed to initiate a strategic review of these questions and to produce a synthesis document where the recommendations could be presented to Member countries as a proposal for action. A small group of NSC members was formed to draft a first version of such a report. The group met at the end of January 1993 to discuss the layout and content of the document and started to write the different chapters. A draft version of the report was then discussed at a NEA Think Tank meeting at the end of May 1993, followed by an in-depth discussion at the Nuclear Science Committee meeting in early June 1993. The comments and suggestions from these meetings have been incorporated in the present report. 6 annexes

    The International Reporting System for Operating Experience (IRS) is an international system jointly operated by the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (OECD/NEA). The fundamental objective of the IRS is to contribute to improving the safety of commercial nuclear power plants which are operated worldwide. This objective can be achieved by providing timely and detailed information on lessons learned from operating and construction experience at the international level. This information could be related to issues and events that are related to safety. The purpose of these guidelines is to describe the system and to give users the necessary background and guidance to enable them to produce IRS reports meeting a high standard of quality while retaining the effectiveness of the system expected by all Member States operating nuclear power plants. As this system is owned by the Member States, the IRS Guidelines have been developed and approved by the IRS National Co-ordinators with the assistance of both Secretariats (IAEA/NEA).

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

    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.

Se muestra que en todos los casos, estas son manifestaciones de una «literatura» de guerra, no de la posguerra. This study analyzes the panorama of contemporary Central American narrative, written by authors born between 1950 and 1964. It is a generation that has opted for innovative narrative esthetics, which is clearly distinguishable from that used by previous groups. Two characteristics stand out in their literary perspectives: 1. contemporary urban themes with a complex network of material conditions and social interactions; 2. the particular treatment of the historical period with its allusions to events of social and poetic history. In all cases, it is clear that they are manifestations of war, rather than postwar, literature.

    In the area of criticality safety, management of spent nuclear fuel is a key issue for many NEA member countries. The importance of measured isotopic assay data from Post-Irradiation Examination (PIE) experiments to validate computer code predictions of spent fuel composition used in safety-related studies has long been recognized by members of the OECD/NEA/NSC/WPNCS (Working Party on Nuclear Criticality Safety). These data are particularly important in criticality analyses related to any application of burnup credit as well as to evaluation of criticality and safety in geologic repositories and fuel cycle applications such as reprocessing. Under the auspices of the WPNCS, an Expert Group on assay data has been formed to share best-practice radiochemical analysis methods, computational analysis procedures and data needs, and isotopic validation data. Through member country collaboration, the database of publicly available spent fuel measurements is being revised and expanded to include more recent measurements, with findings to be documented in a state-of-the-art report.

    2006-01-01

    A key challenge in the development of safety cases for geological repositories is associated with the long periods of time over which radioactive wastes that are disposed of in repositories remain hazardous. The OECD Nuclear Energy Agency (NEA) has recently examined issues related to timescales in the context of two projects under the auspices of the Radioactive Waste Management Committee (RWMC): the Timescales Initiative and the Long-Term Safety Criteria (LTSC) Initiative. These projects examine, respectively, the treatment of timescales in actual safety cases and in the development of radiological protection criteria for geological disposal. They treat different aspects of timescales but have some overlap and have shown some convergence of the results achieved to date. Based on these projects, this paper examines general considerations in the handling of timescales, including ethical principles, evolution of the hazards of radioactive waste over time, and uncertainty in the evolution of repository systems (including geological features). The implications of these considerations are examined in terms of repository siting; levels of protection in regulations; planning for pre-closure and post-closure actions; and development and presentation of safety cases. A comparison is made with previous NEA work related to timescales, in order to show evolutions in current understanding. (authors)

    2007-01-01

    Two subjects - stress corrosion cracking (SCC) and degradation of cable insulation - were selected as the focus of the SCC and Cable Ageing Project (SCAP) due to their relevance for plant ageing assessments and their implication on inspection practices. Fourteen NEA member countries agreed to contribute to the project. The main SCAP objectives are to: establish a complete database with regard to major ageing phenomena for SCC and degradation of cable insulation through collective efforts by OECD/NEA members; establish a knowledge base in these areas by compiling and evaluating the collected data and information systematically; perform an assessment of the data and identify the basis for commendable practices which would help regulators and operators to enhance ageing management. The aim of the knowledge base is to provide a state-of-the-art description of the degradation mechanisms, the main influencing factors, the most susceptible materials and locations, and common strategies available for mitigation and repair. The SCAP project is currently in the development phase, defining and refining the database performance requirements, data format and coding guidelines. The project is scheduled to last four years. It is anticipated that the database definition and the collection of data from member countries will take approximately two years. The subsequent assessment and the commendable practices report are expected to take one year each

    2018-07-22

    Nuclear reactor codes require validation with appropriate data representing the plant for specific scenarios. The thermal-hydraulic data is scattered in different locations and in different formats. Some of the data is in danger of being lost. A relational database is being developed to organize the international thermal hydraulic test data for various reactor concepts and different scenarios. At the reactor system level, that data is organized to include separate effect tests and integral effect tests for specific scenarios and corresponding phenomena. The database relies on the phenomena identification sections of expert developed PIRTs. The database will provide a summary of appropriate data, review of facility information, test description, instrumentation, references for the experimental data and some examples of application of the data for validation. The current database platform includes scenarios for PWR, BWR, VVER, and specific benchmarks for CFD modelling data and is to be expanded to include references for molten salt reactors. There are place holders for high temperature gas cooled reactors, CANDU and liquid metal reactors.

    Full Text Available Este trabajo reporta resultados de un proyecto de investigación que analiza el uso de las tecnologías de la Información y de la Comunicación (TIC en los cursos en línea universitarios en Francia y en México. El marco teórico del estudio se deriva de la perspectiva francófona sobre los usos sociales de las TIC. Desde este enfoque, la apropiación del usuario de las tecnologías y servicios en línea es crucial para entender su desempeño académico porque las TIC se consideran construcciones sociales con diferentes significados, dependiendo de sus usuarios y contextos de uso. Este documento presenta los resultados de 25 entrevistas semiestructuradas con estudiantes de dos universidades mexicanas: la UdG Virtual y la UABC. Los resultados sugieren que el aprendizaje en línea atiende una variedad de necesidades de los estudiantes, incluyendo ayudarles a comprender la lógica de uso de la computadora y software básico, como fue el caso de algunos estudiantes de nuevo ingreso en la UABC, hasta el reconocimiento y validación de habilidades profesionales en el caso de los estudiantes adultos de la UdG Virtual. En general, los discursos de los alumnos mostraron diferentes niveles de apropiación y diferentes formas de utilización de los programas en línea disponibles, pero para la mayoría de los estudiantes, el aprendizaje en línea significó una oportunidad para avanzar académicamente, lo que no hubiera sido posible de otra manera. This paper reports results from a research project that analyzes the use of Information and Communication Technologies (ICTs in online higher education courses in France and Mexico. The francophone perspective on the development of the social uses of ICTs informs the theoretical approach.

    The NEA Data Bank is an international centre of reference for basic nuclear tools used in the analysis and prediction of phenomena in different nuclear applications. The Data Bank collects and compiles computer codes and scientific data and contributes to their improvement for the benefit of scientists in its member countries. In line with this mission, the Data Bank is a core centre of the International Network of Nuclear Reaction Data Centres (NRDC), which co-ordinates the worldwide collection, compilation and dissemination of nuclear reaction data. The NRDC network was established in 1976 from the earlier Four-Centres' Network created in 1966 by the United States, the NEA, the International Atomic Energy Agency (IAEA) and the former Soviet Union. Today, the NRDC is a worldwide co-operation network under the auspices of the IAEA, with 14 nuclear data centres from 8 countries and 2 international organisations belonging to the network. The main objective of the NRDC is to preserve, update and disseminate experimental nuclear reaction data that have been compiled for more than 40 years in a shared database (EXFOR). The EXFOR database contains basic nuclear data on low- to medium-energy experiments for incident neutron, photon and various charged-particle-induced reactions on a wide range of isotopes, natural elements and compounds. Today, with more than 140 000 data sets from approximately 20 000 experiments, EXFOR is by far the most important and complete experimental nuclear reaction database in the world and is widely used in the field of nuclear science and technology. The Data Bank is responsible for the collection and compilation of nuclear reaction data measured in its geographical area. Since 1966, the Data Bank has contributed around 5 000 experiments to the EXFOR database, and it continues to compile new data while maintaining the highest level of quality throughout the database. NRDC co-ordination meetings are held on a biennial basis. Recent meetings

    1998-01-01

    The Incident Reporting System (IRS) is an international system jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organisation for Economic Cooperation and Development (OECD/NEA). The fundamental objective of the IRS is to contribute to improving the safety of commercial nuclear power plants (NPPs) which are operated worldwide. This objective can be achieved by providing timely and detailed information on both technical and human factors related to events of safety significance which occur at these plants. The purpose of these guidelines, which supersede the previous IAEA Safety Series No. 93 (Part II) and the NEA IRS guidelines, is to describe the system and to give users the necessary background and guidance to enable them to produce IRS reports meeting a high standard of quality while retaining the high efficiency of the system expected by all Member States operating nuclear power plants. These guidelines have been jointly developed and approved by the NEA/IAEA

A doença ocorreu no verão e as lesões foram observadas nas regiões do corpo que ficavam grande tempo em contato com a água em canais de irrigação. Histologicamente observaram-se múltiplos granulomas e piogranulomas contendo escassas imagens negativas de hifas na área central, as quais foram melhor evidenciadas através da técnica de metenamina nitrato de prata de Grocott. O diagnóstico etiológico definitivo foi baseado na técnica de imuno-histoquímica com anticorpo policlonal anti-Pythium insidiosum. Adicionalmente, foi realizado o teste de ELISA indireto. Surtos de pitiose cutânea bovina são incomuns e, particularmente neste relato, todos os animais afetados tiveram cura espontânea das lesões dentro de duas a três semanas.Seventy-six young mixed breed cattle of both sexes, presented multifocal ulcerated nodular cutaneous lesions localized in the medial and lateral aspects of fore and hindlimbs, ventral neck, sternum, and tail. The disease occurred during summer and lesions were observed on areas of the body which were in contact with water of irrigation channels for long periods. Histologically, there were multiple granulomas and pyogranulomas with few negative profiles of hyphae, which were better visualized throughout Grocott methenamine silver stain. Definitive etiologic diagnosis was based on immuno-histochemistry with anti-Pythium insidiosum polyclonal antibody. Additionally, an indirect ELISA test was performed. Bovine cutaneous pythiosis outbreaks are uncommon and, particularly as occurred in the cattle of this report, all affected animals had spontaneous healing within two to three weeks.

    1999-01-01

    A working group of the Nuclear Energy Agency has developed a database of features, events and processes (FEPs) relevant to the assessment of the long-term safety of radioactive waste disposal facilities. The Environment Agency participated in this work as described in a previous report, R and D Technical Report P97. This report describes work done in order to (i) provide an electronic version of the NEA International FEP Database in a convenient form suited to the Agency's needs; (ii) determine procedures for use of the Database in support of the Agency's review of an applicant's safety case for solid radioactive disposal, and in other appropriate Agency activities. Section 1 of the report outlines the objectives and work done. Section 2 gives an overview of the current status, development and international use of the NEA FEP Database. Alternative uses of the Database by the Agency, and procedures for use, are discussed in Section 3. Two alternative procedures for use of the Database in scientific and technical review of an applicant's safety case are outlined and compared; these provide a framework for orderly identification and discussion of technical issues within the review. It is concluded that the way in which the Database is used will depend on the circumstances and also the aims and preferences of the Agency. Detailed procedures for the use of the Database are best defined for the specific circumstances, taking account of the level of information available from the applicant, and the time and resources which the Agency may wish to devote to a given phase of review. The NEA FEP Database has been developed as a tool to assist in performing or reviewing safety assessments of radioactive waste disposal facilities. The principle of the Database, and also the software framework, may be equally applicable to other technical or scientific assessments, e.g. of landfill facilities or river catchment pollution studies. Since the Database is now available to the Agency

    2012-01-01

    The current number of known potential NEA targets for HSF is limited to those objects whose orbital characteristics are similar to that of the Earth. This is due to the projected capabilities of the exploration systems currently under consideration and development at NASA. However, NEAs with such orbital characteristics often have viewing geometries that place them at low solar elongations and thus are difficult to detect from the vicinity of Earth. While ongoing ground-based surveys and data archives maintained by the NEO Program Observation Program Office and the Minor Planet Center (MPC) have provided a solid basis upon which to build, a more complete catalog of the NEO population is required to inform a robust and sustainable HSF exploration program. Since all the present NEO observing assets are currently confined to the vicinity of the Earth, additional effort must be made to provide capabilities for detection of additional HSF targets via assets beyond Earth orbit. A space-based NEO survey telescope located beyond the vicinity of the Earth, has considerable implications for planetary science and astrobiology. Such a telescope will provide foundational knowledge of our Solar System small body population and detect targets of interest for both the HSF and scientific communities. Data from this asset will yield basic characterization data on the NEOs observed (i.e., albedo, size determination, potential for volatiles and organics, etc.) and help down select targets for future HSF missions. Ideally, the most attractive targets from both HSF and astrobiology perspectives are those NEAs that may contain organic and volatile materials, and which could be effectively sampled at a variety of locations and depths. Presented here is an overview of four space-based survey concepts; any one of which after just a few years of operation will discover many highly accessible NEO targets suitable for robotic and human exploration. Such a space-based survey mission will reveal

  17. Fuel safety criteria in NEA member countries - Compilation of responses received from member countries

    International Nuclear Information System (INIS)

    2003-03-01

    In 2001 the Committee on the Safety of Nuclear Installations (CSNI) issued a report on Fuel Safety Criteria Technical Review. The objective was to review the present fuel safety criteria and judge to which extent they are affected by the 'new' design elements, such as different cladding materials, higher burnup, the use of MOX fuels, etc. The report stated that the current framework of fuel safety criteria remains generally applicable, being largely unaffected by the 'new' or modern design elements. The levels (numbers) in the individual safety criteria may, however, change in accordance with the particular fuel and core design features. Some of these levels have already been - or are continuously being - adjusted. The level adjustments of several other criteria (RIA, LOCA) also appears to be needed, on the basis of experimental data and the analysis thereof. As a follow-up, among its first tasks, the CSNI Special Expert Group on Fuel Safety Margins (SEG FSM) initiated the collection of information on the present fuel safety criteria used in NEA member states with the objective to solicit national practices in the use of fuel safety criteria, in particular to get information on their specific national levels/values, including their recent adjustments, and to identify the differences and commonalties between the different countries. Two sources of information were used to produce this report: a compilation of responses to a questionnaire prepared for the June 2000 CNRA meeting, and individual responses from the SEGFSM members to the new revised questionnaire issued by the task Force preparing this report. In accordance with the latter, the fuel safety criteria discussed in this report were divided into three categories: (A) safety criteria - criteria imposed by the regulator; (B) operational criteria - specific to the fuel design and provided by the fuel vendor as part of the licensing basis; (C) design criteria - limits employed by vendors and/or utilities for fuel

    Full Text Available La abdominoplastia es una de las intervenciones quirúrgicas de mayor solicitud por parte de los pacientes dentro de la Cirugía Plástica. Uno de los inconvenientes que pueden presentarse después de su realización es la disminución o pérdida de sensibilidad cutánea de la pared abdominal como consecuencia de la disección de los nervios tóraco-abdominales al elevar el colgajo cutáneo, que se presenta hasta en un 57-72 % de los pacientes. Nuestro objetivo es determinar los trastornos de la sensibilidad cutánea superficial que se producen en el abdomen tras una abdominoplastia y el tiempo necesario para recuperar esa sensibilidad. Realizamos un estudio observacional, prospectivo, de cohorte, en el cual se incluyen 50 pacientes de sexo femenino, en dos grupos: un grupo control, al cual no se le realizó abdominoplastia, constituido por 20 mujeres con edades entre 24-40 años (promedio de 29.6 años y sin cirugías abdominales previas, comorbilidades cutáneas ni sistémicas, y un grupo de estudio compuesto por 30 pacientes de edades comprendidas entre los 22-57 años (promedio de 36.2 años, con características similares a las del grupo control, a las cuales se les realizó abdominoplastia.

    An OECD/NEA expert group has compiled international data on existing minimum critical values for UO 2 -, PuO 2 -, UNH- and PuNH-systems to identify any significant discrepancies in the data and to propose explanations. The paper examines the spread of the compiled data and the influence of the time of generation of the data on the spread. It turns out, that the remarkable spread reduces by omitting values older than five years. Considering only data generated in the last three years, the spread further reduces. The number of cases with a large spread in the reported minimum critical values falls from 28 to four cases, and the smallest and largest data values converge. (author)

    Versteeg, M.F.; Andrews, R.M.

    1994-01-01

    Almost every member country of the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD) uses probabilistic safety criteria (PSC), in one way or another, for the safety assessment of nuclear power plants. The choice of the PSC, their applicability, and whether or not these PSC are used in a formal and/or legal way, is dependent on the political and regulatory situation. The spectrum of utilization includes the use as design requirements and the use as a regulatory and licensing tool be the authorities. The paper summarises the various PSC applied to the assessment of nuclear power plant in the OECD member countries and presents in more detail the use of PSC on the public health level in the Netherlands, United Kingdom and USA. 10 refs, 1 fig., 6 tabs

    2009-01-01

    Since the International Commission on Radiological Protection (ICRP) initiated a dialogue in 1999 on the evolution of the system of radiological protection, the NEA Committee on Radiation Protection and Public Health (CRPPH) has actively engaged in providing the ICRP with input and views. The Committee's work on this subject has included eight expert group reports, seven international conferences, and four detailed review and comment assessments of draft ICRP recommendations. This report presents a chronological summary of the issues, views and concerns raised by the CRPPH as the ICRP issued various draft versions of its new recommendations (ICRP Publication 103, published in December 2007), and of the response by the ICRP as seen in its subsequent draft recommendations. The interest of this summary report is that it will not only assist readers in understanding the main themes and concepts of the new ICRP recommendations, but also why and how the changes from the previous ICRP Publication 60 recommendations came about.

    This paper describes analyses of the OECD/NEA HTR benchmark organized by the 'Working Party on the Scientific Issues of Reactor Systems (WPRS)', formerly the 'Working Party on the Physics of Plutonium Fuels and Innovative Fuel Cycles'. The benchmark was specifically designed to provide inter-comparisons for plutonium and thorium fuels when used in HTR systems. Calculations considering uranium fuel have also been included in the benchmark, in order to identify any increased uncertainties when using plutonium or thorium fuels. The benchmark consists of five phases, which include cell and whole-core calculations. Analysis of the benchmark has been performed by a number of international participants, who have used a range of deterministic and Monte Carlo code schemes. For each of the benchmark phases, neutronics parameters have been evaluated. Comparisons are made between the results of the benchmark participants, as well as comparisons between the predictions of the deterministic calculations and those from detailed Monte Carlo calculations.

    International Nuclear Information System (INIS)

    1996-01-01

    This workshop was hosted jointly by the Swedish Nuclear Power Inspectorate (SKi) and the Swedish Royal Institute of Technology (KTH). It was sponsored by the Principal Working Group 3 (PWG-3) of the NEA CSNI. PWG-3 deals with the integrity of structures and components, and has three sub-groups, dealing with the integrity of metal components and structures, ageing of concrete structures, and the seismic behaviour of structures. The sub-group dealing with metal components has three mains areas of activity: non-destructive examination; fracture mechanics; and material degradation. The topic of this workshop is primarily probabilistic fracture mechanics, but probabilistic integrity analysis includes NDE and materials degradation also. Session 1 (5 papers) was devoted to the development of probabilistic models; Session 2 (5 papers) to the random modelling of defects and material properties; Session 3 (8 papers) to the applications of probabilistic modelling to nuclear components; Sessions 4 is a concluding panel discussion

    2009-01-01

    In this paper we present the Univ. of Pisa preliminary results for the first exercise of the Phase I of the OECD/NEA Benchmark on the Uncertainty in Analysis and Modeling. The scope of exercise one is to address the uncertainties due to the basic nuclear data as well as the impact of processing the nuclear and covariance data, selection of multi-group structure and self-shielding treatment. DRAGON code and TSUNAMI code were employed, using the available covariance data matrix. The execution of DRAGON calculations required the use of ANGELO and LAMBDA codes for the extension of the covariance matrix from the original SCALE 44 group structure to DRAGON 69 group structure. The uncertainties for the main cross sections were evaluated and are presented here. (authors)

    1984-01-01

    A geochemical and biological study of the sea floor at the NEA dumpsite for low-level radioactive waste is reported. The sea bottom has rather steep hillsides. Slumps are usual phenomena and could be triggered by the dumping operations. The sediment is described in terms of its mineralogical and elemental composition. The variation in CaCO 3 content accounts for most of the variation in the elemental composition and cation exchange capacity. The present depth of the lysocline is shown to be about 4700 m. A description is given of the early diagenetic processes: (1) Mineralization of organic material, (2) Cation exchange, (3) Change in redox conditions and (4) Carbonate dissolution and recrystallization; and discussed in terms of their effects on the redistribution and transport of trace elements and radionuclides within the sediment and between sediment and overlying water.

    2010-04-01

    Full Text Available O estudo da barreira cutânea e de suas propriedades ganhou impulso a partir da década de 60, com estudos que apontaram sua resistência de forma isolada e suas propriedades com relação à permeação cutânea. Paralelamente, a descrição dos corpos de Odland auxiliou a compreensão da manutenção da estabilidade da camada córnea. O modelo brick & mortar, em que os corneócitos são os tijolos e o cimento são os lipídeos intercelulares, é o mais aceito, até o momento. Atualmente, há evidências consistentes de que o estrato córneo é uma estrutura metabolicamente ativa e exerce funções adaptativas. A barreira cutânea também tem um papel na resposta inflamatória, com ativação de melanócitos, angiogênese e fibroplasia, cuja intensidade depende, basicamente, da intensidade da agressão. As anormalidades da barreira cutânea da dermatite atópica são clinicamente observáveis pela presença de pele seca, achado muito frequente e significativo, que constitui parâmetro iagnóstico e de acompanhamento. O grau de hidratação da camada córnea, assim como a perda de água transepidérmica (transepidermal water loss - TEWL, estão relacionados com o grau de dano à barreira, constituindo parâmetros biofísicos que permitem acompanhar os pacientes de maneira não invasiva e com maior grau de sensibilidade.Research about the skin barrier and its properties has increased significantly since the 60s, with studies that indicated its resistance when isolated, as well as its particularities in relation to skin permeability. At the same time, description of Odland bodies helped to understand how stratum corneum stability is maintained. The “brick and mortarâ€� model is the most accepted so far. In this analogy, the corneocytes are the bricks and the intercellular lipids are the mortar. Currently, there is concrete evidence that the stratum corneum is an active metabolic structure that holds adaptive functions, interacting

    1998-01-01

    New issues in criticality safety continue to emerge as spent fuel storage facilities reach the saturation point, fuel enrichments and burn-ups increase and new types of plutonium-carrying fuels are being developed. The new challenges related to the manipulation, transportation and storage of fuel demand further work to improve models predicting behavior through new experiments, especially where there is a lack of data in the present databases. This article summarizes the activities of the OECD/NEA working groups that coordinate and carry out work in the domain of criticality safety. Particular attention is devoted to establishing sound databases required in this area and to addressing issues of high relevance such as burn-up credit. This is aimed toward improving safety and identifying economic solutions to issues concerning the back end of the fuel cycle

    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.

    1996-01-01

    The Nuclear Energy (NEA) Co-operative Programme on Decommissioning established the Task Group on Recycling and Reuse in 1992. The Task Group was charged with examining means for maximizing the recovery of valuable materials that partially comprise waste resulting from decommissioning activities. The Task Group also was to examine means for minimising the quantity of waste from such operations. Much of the Task Group's work has been concentrated on metal recycling and reuse. The Task Group's examination and report are the product of experts from seven countries and constitute a synthesis of surveys, analyses, and case studies. The report is intended to provide information and insights, as of the end of 1994, into the practicality and usefulness of release criteria from the perspective of organisations currently engaged in actual decommissioning activities

    A Working Group established by the organization for Economic Co-operation and Development's Nuclear Energy Agency (OECD-NEA), Paris, has examined the validity of computational methods used for calculations that evaluate the nuclear criticality safety issues involved in the storage, handling and transportation of fissile materials. The basic goal of this Working Group is to attempt to define and implement a procedure that can be shown to demonstrate the validity of the various computational methods used to make criticality safety calculations. The current activities of the Working Group involve an effort to establish the validity of computational methods used to evaluate the criticality safety of the storage, handling, and transportation of spent light-water-reactor fuel elements in which one seeks to take credit for the fissile material burnup and/or buildup of fission products.

    1994-01-01

    The paper presents an overview of the recent study carried out by OECD's Nuclear Energy Agency on the economics of the nuclear fuel cycle. The investment appraisal method of deriving the lifetime levelised fuel cost required the examination of the entire fuel cycle cash outflow based on component prices. The cash outflows were discounted to a base date using the selected discount rate which was set, for the reference case, at 5 per cent per annum (real). The levelised fuel cycle cost was derived in mills/kWh terms by equating the net present value of the entire fuel cycle cost and the net present value of the total electrical output over the station lifetime, where both have been discounted to the same date. The study's reference fuel cycle options and costs are discussed and a comparison with earlier NEA work is provided. 6 refs., 2 tabs., 3 figs

Ao invés de a teoria organizacional compor um conjunto unificado de conceitos e interpretações, mostra-se fortemente diversificada e conflituosa entre os vários agentes e suas respectivas formas de "enxergar" a organização. O objetivo deste artigo é apresentar algumas perspectivas teóricas contemporâneas em análise organizacional: dependência de recursos, ecologia das populações, contingência estrutural, nova economia institucional e novo institucionalismo. Essas perspectivas representam sinais importantes para o avanço e sistematização das análises organizacionais contemporâneas, uma vez que há uma crescente tentativa em construir pontes entre as perspectivas econômicas e sociológicas, estruturais e racionais, e entre teorias institucionais e ecológicas. Busca-se, com esse referencial teórico, apresentar conceitos, níveis de análise, principais variáveis, críticas e principais autores através de um quadro de referência das respectivas perspectivas apontadas para que novas abordagens sejam reconhecidas e analisadas.The evolution of organizational studies comprises different and contrasting approaches.

A história da joalheria e a da estética são relacionadas, ressaltando as mudanças sociológicas das principais rupturas escolásticas nas artes e na filosofia das formas. A atividade do designer de joias está atrelada aos estudos do mercado, da trajetória do belo, na sociedade, com o objetivo de encarnar na forma e sua essência no objeto estético. O conhecimento em profundidade sobre o belo e suas categorias estéticas seguem o seu tempo e mercado, permitindo ao designer liberar o caminho para o juízo crítico, a faculdade de pensar a forma, na fronteira entre teoria e prática, emoção e cálculo. A joia contemporânea reluz o belo, a técnica, a ideia, o imaginário. A estética contemporânea pondera a escassez de matéria-prima e os vários pensamentos que refletem na criação da forma. O conteúdo deste texto pincela brevemente a importância do conhecimento do designer no desenvolvimento de novas formas para atender às exigências do mercado.

    2013-03-01

    Full Text Available O arranjo e a descrição dos documentos de arquivo podem ser considerados os dois processos nucleares da teoria e da prática arquivística que compartilham o mesmo objetivo: representar o conhecimento arquivístico. Esta representação está baseada fundamentalmente na aplicação do princípio da proveniência e no conceito de fundo documental. O presente artigo busca discutir especificamente a descrição arquivística, em face das mudanças e propostas de uma abordagem pós-moderna da disciplina que propõe o conceito de fundo e o princípio da proveniência como norteadores conceituais e não como entidades físicas – como até o momento se supunha – no processo de representação. Para tanto, são apresentadas as perspectivas teóricas dos estudos canadenses e australianos que se apresentam na vanguarda do movimento pós-moderno, discutindo as bases teóricas da Arquivística Moderna, face à realidade dinâmica da produção documental contemporânea. Ao final, concluí-se que a abordagem pós-moderna parece ser a mais capacitada para lidar com as questões contemporâneas, uma vez que vai mais fundo nas questões sobre a representação arquivística e sua relação entre o arquivista, o contexto de criação dos documentos e o usuário.

    International Nuclear Information System (INIS)

    2013-01-01

    A wide spectrum of argillaceous media are being considered in Nuclear Energy Agency (NEA) member countries as potential host rocks for the final, safe disposal of radioactive waste, and/or as major constituent of repository systems in which wastes will be emplaced. In this context, the NEA established the Working Group on the 'Characterisation, the Understanding and the Performance of Argillaceous Rocks as Repository Host Formations' in 1990, informally known as the 'Clay Club'. The Clay Club examines various argillaceous rocks that are being considered for the underground disposal of radioactive waste, ranging from soft clays to indurated shales. Very generally speaking, these clay rocks are composed of fine-grained minerals showing pore sizes from < 2 nm (micropores) up to > 50 nm (macro-pores). The water flow, solute transport and mechanical properties are largely determined by this microstructure, the spatial arrangement of the minerals and the chemical pore water composition. Examples include anion accessible ('geochemical') porosity and macroscopic membrane effects (chemical osmosis, hyper-filtration), geomechanical properties and the characteristics of two-phase flow properties (relevant for gas transport). At the current level of knowledge, there is a strong need to improve the nanoscale description of the phenomena observed at a more macroscopic scale. However, based on the scale of individual clay-minerals and pore sizes, for most of the imaging techniques this resolution is a clear challenge. The workshop, hosted by the Institute for Nuclear Waste Disposal (INE), Karlsruhe Institute of Technology (KIT) in the Akademiehotel Karlsruhe (Germany) from 6 to 8 September 2011, was intended to give, inter alia, a discussion platform on: - The current state-of-the-art of different spectro-microscopic methods - New developments addressing the above mentioned knowledge gaps in clays. - The perception of the interplay between geometry

    Full Text Available La idea central del artículo es que la hipótesis de las líneas de fuga sencillamente orienta el problema general de las resistencias difusas. Se sostiene que abordar la cuestión de cómo cambian y se transforman las sociedades depende de acotar el terreno de la investigación más allá de los fenómenos de rechazo, inconformidad y divergencia colectiva. Desde ese punto de vista, se intenta diferenciar entre: i las campañas cuyo esfuerzo colectivo se traslada a la reivindicación política; ii las coaliciones en las reuniones públicas, los mítines, las manifestaciones, peticiones o declaraciones, procesiones solemnes y vigilias; y iii los fenómenos de innovación social. Se trata de mostrar que se puede considerar a los movimientos sociales en el contexto de situaciones decisivas de la transformación radical de la experiencia social ganando en una definición que excede la cuestión del activismo popular y la lucha por la transformación política del Estado. La naturaleza de la investigación es teórica, luego su metodología tiene que ver con el planteamiento general de la hipótesis filosófica de las líneas de fuga, en su compresión como orientación sociológica general.

    The study presented in this report is a continuation of work conducted for SKI in 1998 on the identification of Common Cause Initiators (CCIs) based on operational events documented in the NEA Incident Reporting System (IRS). Based on the new operational experience accumulated in IRS in the period 1995-2006, the project focused on the identification of new CCI events. An attempt was also made to compare the observations made in the earlier study with the results of the current work. The earlier study and the current project cover the events reported in the IRS database with the incident date in the period from 01.01.1980 to 15.11.2006. The review of the NEA IRS database conducted within this project generated a sample of events that provides insights regarding the Common Cause Initiators (CCIs). This list includes certain number of 'real' CCIs but also potential CCIs and other events that provide insights on potential dependency mechanisms. Relevant characteristics of the events were analysed in the context of CCIs. This evaluation was intended to investigate the importance of the CCI issue and also to provide technical insights that could help in the modelling the CCIs in PSAs. The analysis of operational events provided useful engineering insights regarding the potential dependencies that may originate CCIs. Some indications were also obtained on the plant SSCs/areas that are susceptible to common cause failures. Direct interrelations between the accident mitigation systems through common support systems, which can originate a CCI, represent a dominant dependency mechanism involved in the CCI events. The most important contributors of this type are electrical power supply systems and I-and-C systems. Area-related events (fire, flood, water spray), external hazards (lightning, high wind or cold weather) and transients (water hammer, electrical transients both internal and external) have also been found to be important sources of dependency that may originate CCIs

    Sea dumping operations of certain types of packaged low and medium-level radioactive wastes have been carried out since 1967 in the North-East Atlantic under the auspices of the OECD Nuclear Energy Agency. On the occasion of the 1980 review of the continued suitability of the North-East Atlantic site used for the disposal of radioactive waste, it was recommended that an effort should be made to increase the scientific data base relating to the oceanographic and biological characteristics of the dumping area. In particular, it was suggested that a site specific model of the transfer of radionuclides in the marine environment be developed, which would permit a better assessment of the potential radiation doses to man from the dumping of radioactive waste. To fulfill these objectives a research and environmental surveillance programme related to sea disposal of radioactive waste was set up in 1981 with the participation of thirteen Member countries and the International Laboratory for Marine Radioactivity of the IAEA in Monaco. The research program is focused on five research areas which are directly relevant to the preparation of more site-specific assessments in the future. They are: model development; physical oceanography; geochemistry; biology; and radiological surveillance. Promising results have already been obtained and more are anticipated in the not too distant future. An interim description of the NEA dumping site has been prepared which provides an excellent data base for this area (NEA 1983).It includes data in bathymetry, isopycnal topography, local and larger scale currents, sediment distribution and sedimentary processes, hydrochemistry, deep ocean biology and results of radiochemical analyses of sea water, sediments and biological materials. The modelling work is also well advanced allowing comparison of results obtained from different codes. After integration of the models, sensitivity analyses will provide indications for future research needs

Determinaram-se as áreas da lesão, e amostras de pele, fígado e rins foram coletadas para avalição histológica. Aos 21dias, amostras de pele foram coletadas para análise tensiométrica. Clinicamente, todos os grupos de tratamento apresentaram evolução cicatricial fisiológica. Os grupos U 0,1% e U 0,01% apresentaram maior presença de epitelização aos sete dias e maior retração cicatricial aos quatro dias. Na histologia, U 0,1% e U 0,01% apresentaram aos quatro e sete dias maior quantidade de fibrina e inflamação que V e SF, e, nos demais momentos, não houve diferenças entre os grupos. Quanto à fase cicatricial, aos quatro dias todos os grupos encontravam-se na fase inflamatória, aos sete dias U 0,1% e U 0,01% permaneciam na fase inflamatória, diferindo de SF e V, que se caracterizavam na fase proliferativa. Aos 14 dias, os grupos apresentavam-se em transição de fase proliferativa para maturação e, aos 21dias, estavam todos na fase de maturação. Os grupos tratados com urucum expressaram menor resistência à tensão que V e SF. Concluiu-se com este estudo que o extrato oleoso de urucum acelera o processo cicatricial nos primeiros dias, mas proporciona uma cicatriz de baixa qualidade.

    The two-day workshop held at the OECD Headquarters in Paris on 7-8 July 2015, brought together some of the leading experts in the field of nuclear fission research, development and demonstration. The purpose was to launch the NEA Nuclear Innovation 2050 Initiative, aiming, after a first survey phase, at producing a road-map of main priority research programmes and infrastructures necessary to support the role nuclear energy may play in the low carbon power sector of the future. This might then further lead to some ad-hoc cooperation frameworks that help to effectively implement key priorities coming out of the road-mapping. The workshop was organised into the following five sessions: 1 - Opening session on NI2050: vision and main objectives; 2 - National presentations on nuclear fission research and innovation activities (programmes, infrastructures, budgets); 3 - Presentations on some existing international nuclear fission road-maps and co-operation frameworks; 4 - Defining the way forward for NI2050: survey, road-mapping and priorities and co-operation; 5 - Open discussion. These proceedings bring together the available presentations (slides) given during the workshop: 1. Opening session on NI2050: vision and main objectives: Setting the scene: NEA/IEA Nuclear Energy road-map 2050 (Jaejoo Ha); Proposed scope and organisation of the NI2050 project launching, taking stock of the IEA Energy RD and D survey and going further (Marc Deffrennes); 2.

    The Committee on the Safety of Nuclear Installations (CSNI) of the OECD-NEA co-ordinates the NEA activities concerning the technical aspects of design, construction and operation of nuclear installations insofar as they affect the safety of such installations. The Integrity and Ageing Working Group (IAGE WG) of the CSNI deals with the integrity of structures and components, and has three sub-groups, dealing with the integrity of metal components and structures, ageing of concrete structures, and the seismic behaviour of structures. The sub-group dealing with the seismic behaviour of structures proposed this workshop. The OECD-NEA workshop on the relations between seismological data and seismic engineering analyses was held on October 17-18, 2002. A field visits in the Izmit area where the fault scarp is still visible was organised on Wednesday October 16, 2002. The Ttirkiye Atom Enerjisi Kurumu, TAEK (Turkish Atomic Energy Agency) in Istanbul, Turkey, hosted the workshop. A recommendation of the OECD workshop on the engineering characterisation of seismic input (hosted by the United States Nuclear Regulatory Commission and organised by Brookhaven National Laboratory on November 15-17, 1999) was to foster the growth of interaction between 'design engineers' and 'ground motion specialists'. The objective of the Istanbul workshop is to address this recommendation. The workshop gave seismologists the opportunity to present observed damages and their related ground motions and design engineers the opportunity to present current techniques used in the evaluation of seismic hazards. Bridging the gap between these two fields was a key objective - this workshop was a forum for bringing together the two communities. In addition, the location of the workshop was particularly interesting and provided possibilities for several of the host country participants to discuss the 1999 Kocaeli earthquake. On the basis of lessons learned from large earthquakes over the last decade, the

Esta se acompaña de un descenso en la presión del líquido cefalorraquídeo (LCR y un realce difuso de las paquimeninges evidenciable en la resonancia magnética encefálica, sin que medie historia de trauma craneoencefálico o punción lumbar. Mujer de 24 años de edad sin antecedentes de importancia y cefalea holocraneana de carácter opresivo de 15 días de evolución. La misma se exacerbaba con la bipedestación y cedía con el decúbito. En la punción lumbar se observó pleocitosis a predominio linfocítico, hiperproteinorraquia y abundantes glóbulos rojos, siendo la presión de apertura del LCR de 20 mm H2O. La resonancia magnética encefálica mostró un realce paquimeníngeo difuso luego de la administración del gadolinio. La cisternografía radioisotópica con tecnecio 99 señaló el sitio de pérdida de LCR a nivel dorsal alto, confirmándose la sospecha diagnóstica de hipotensión intracraneal espontánea. La paciente recibió tratamiento médico conservador con evolución clínica favorable. Los hallazgos en los exámenes complementarios y las características clínicas de la cefalea, permitirán confirmar el diagnóstico de hipotensión intracraneal espontánea, evitando de esta manera la realización de procedimientos innecesarios.Spontaneous intracranial hypotension is an infrequent clinical entity characterized by orthostatic headache, low cerebrospinal fluid pressure, and magnetic resonance imaging findings of diffuse pachymeningeal gadolinium enhancement without previous history of head trauma or lumbar puncture.

    Full Text Available Este artículo presenta una experiencia pedagógica, empírica y formal de las autoras dentro de las aulas de clase y cómo a partir de ésta, surge la idea de crear un material didáctico para el área de Español y Literatura como instrumento a través del cual se genere un acercamiento hacia el proceso lectoescritor del niño-joven, entre los 10 y los 12 años de edad. Para la creación de este material didáctico, el primer paso se dio con la lectura juiciosa de escritores y teóricos que nos formaron una imagen mental de los elementos que podían orientarnos a nivel psicológico, artístico y literario para sustentar la organización de las actividades presentadas en la cartilla del estudiante, entre ellos se destacan el suizo Jean Piaget con su teoría del desarrollo cognitivo, en el aspecto literario, nos servimos del cuento como base para la elaboración de las actividades de lectoescritura; empleando el punto y la línea como elementos de representación gráfica que generasen en los niños la idea de involucrarse en el proceso de escritura desde el reconocimiento de éstos como entes primarios constitutivos de las letras que posteriormente serán las palabras que conforman cualquier tipo de texto escrito. Al contar con esta fundamentación teórica, nos dimos a la tarea de diseñar actividades que fomentasen el desarrollo de las competencias comunicativas en los estudiantes; de esta forma, cada una de ellas se organizó de forma coherente por talleres en una cartilla intitulada: Punto y Línea: Llaves maestras a mundos imaginarios. Como material de apoyo complementario, se escribió la respectiva guía del docente, en la cual están contenidas las actividades de la cartilla y la respectiva explicación para su uso por parte del docente.

    All NEA member countries, whether or not they have nuclear power plants, are faced with appropriately managing non-nuclear radioactive waste produced through industrial, research and medical activities. Sources of such waste can include national laboratory and university research activities, used and lost industrial gauges and radiography sources, hospital nuclear medicine activities and in some circumstances, naturally occurring radioactive material (NORM) activities. Although many of these wastes are not long-lived, the shear variety of sources makes it difficult to generically assess their physical (e.g. volume, chemical form, mixed waste) or radiological (e.g. activity, half-life, concentration) characteristics. Additionally, the source-specific nature of these wastes poses questions and challenges to their regulatory and practical management at a national level. This had generated interest from both the radiological protection and radioactive waste management communities, and prompted the Committee on Radiological Protection and Public Health (CRPPH) to organise, in collaboration with the Radioactive Waste Management Committee (RWMC), a workshop tackling some of the key issues of this challenging topic. The key objectives of the NEA Workshop on the Management of Non-Nuclear Radioactive Waste were to address the particularities of managing non-nuclear waste in all its sources and forms and to share and exchange national experiences. Presentations and discussions addressed both technical aspects and national frameworks. Technical aspects included: - the range of non-nuclear waste sources, activities, volumes and other relevant characteristics; - waste storage and repository capacities and life cycles; - safety considerations for mixed wastes management; - human resources and knowledge management; - legal, regulatory and financial assurance, and liability issues. Taking into account the entire non-nuclear waste life-cycle, the workshop covered planning and

    Full Text Available In civil engineering the prestressing methodology enables the engineer to induce in the structure states of stress that are equal and opposite to those due to the applied forces. In underground excavations, when this modifies the state of stress of the rock masses, it is also possible to apply compression stresses which, if rightly orientated, improve the stability of the rock. In this paper details are given of the methods of calculation and execution technology of a project which sought to nullify the thrusts of the vault of an underground power station, so that the stability of the side walls should not be impaired. It is reasoned why it was decided to prestress the rock as a method of achieving this object, and the features and factors which were involved are described. Information is also given of how the factors of safety of certain mountain massifs were improved, after the excavation of the above mentioned power station gave reason to believe that parts of the mountain rock might thereby become heavily overloaded.La técnica del pretensado en las obras civiles, ofrece al Ingeniero la posibilidad de crear unos esfuerzos tales que introduzcan en las estructuras estados tensionales iguales y contrarios a los que se prevea han de producir las solicitaciones. En el campo de las excavaciones subterráneas, y cuando la ejecución de las mismas modifica el estado tensional del macizo «in situ», es también posible crear unos esfuerzos de compresión que, dirigidos adecuadamente, mejoren las condiciones de estabilidad de dicho macizo. En el presente artículo se exponen las bases de cálculo y el sistema de ejecución para conseguir que la descarga de los empujes de la bóveda de u na central subterránea no alterasen las condiciones de estabilidad de los hastiales.

El primero —el de Gran Bretaaña, Bélgica y Holanda— se caracterizó por su gradualismo, tras la renuncia por parte del bloque político secular a apropiarse del Estado y su aceptación de la idea de que éste debía limitarse a proteger la libertad inherente al individuo. En cambio, el modelo de laicismo estatista —vigente en Francia, Italia y, en su versión más extrema, en la España de la II República—, partía de la idea de que el Estado era intérprete absoluto de un poder que no puede fragmentarse sin dejar de ser democrático, y se tradujo en el intento de contrarrestar la presencia católica mediante la imposición de políticas laicas, especialmente en el ámbito de la educación. Palabras Clave: Historia Contemporánea de Europa, Religión, Política, Secularización, Laicismo.

    The Idaho National Laboratory (INL) Very High Temperature Reactor (VHTR) Technology Development Office (TDO) Methods Core Simulation group led the construction of the Organization for Economic Cooperation and Development (OECD) Modular High Temperature Reactor (MHTGR) 350 MW benchmark for comparing and evaluating prismatic VHTR analysis codes. The benchmark is sponsored by the OECD's Nuclear Energy Agency (NEA), and the project will yield a set of reference steady-state, transient, and lattice depletion problems that can be used by the Department of Energy (DOE), the Nuclear Regulatory Commission (NRC), and vendors to assess their code suits. The Methods group is responsible for defining the benchmark specifications, leading the data collection and comparison activities, and chairing the annual technical workshops. This report summarizes the latest INL results for Phase I (steady state) and Phase III (lattice depletion) of the benchmark. The INSTANT, Pronghorn and RattleSnake codes were used for the standalone core neutronics modeling of Exercise 1, and the results obtained from these codes are compared in Section 4. Exercise 2 of Phase I requires the standalone steady-state thermal fluids modeling of the MHTGR-350 design, and the results for the systems code RELAP5-3D are discussed in Section 5. The coupled neutronics and thermal fluids steady-state solution for Exercise 3 are reported in Section 6, utilizing the newly developed Parallel and Highly Innovative Simulation for INL Code System (PHISICS)/RELAP5-3D code suit. Finally, the lattice depletion models and results obtained for Phase III are compared in Section 7. The MHTGR-350 benchmark proved to be a challenging simulation set of problems to model accurately, and even with the simplifications introduced in the benchmark specification this activity is an important step in the code-to-code verification of modern prismatic VHTR codes. A final OECD/NEA comparison report will compare the Phase I and III

    In the recent years, due, among others, the slowing down of the nuclear industry, investment in the development and validation of CFD codes, applied specifically to the problems of the nuclear industry has been seriously hampered. Thus the International Benchmark Exercise (IBE) sponsored by the OECD/NEA have been fundamental to analyze the use of CFD codes in the nuclear industry, because although these codes are mature in many fields, still exist doubts about them in critical aspects of thermohydraulic calculations, even in single-phase scenarios. The Polytechnic University of Valencia (UPV) and the Universitat Jaume I (UJI), sponsored by the Nuclear Safety Council (CSN), have actively participated in all benchmark's proposed by NEA, as in the expert meetings,. In this paper, a summary of participation in the various IBE will be held, describing the benchmark itself, the CFD model created for it, and the main conclusions. (Author)

En el primer ensayo, se sembraron simultáneamente con la alfalfa, ryegrass inglés, rygrass anual y orchoso. Los métodos de siembra utilizados fueron: a alfalfa y gramíneas sembradas al voleo, b alfalfa y gramíneas en el mismo surco, c alfalfa y gramíneas en surcos alternos, d alfalfa en surcos y gramíneas al voleo y e alfalfa en surcos y trébol blanco al voleo. En el segundo experimento se sembró la alfalfa en surcos separados 25 cm. Después de establecida la alfalfa e inmediatamente después del 4° corte se sembraron al voleo las siguientes gramíneas: ryegrass inglés, rygrass anual, orchoro, festuca media, pasto cinta y pasto rescate. Las finalidades del estudio fueron las de valorar el comportamiento de las gramíneas en mezcla con la alfalfa, mediante la determinación progresiva de la composición botánica y el rendimiento de forraje seco de las mezclas. La siembra simultánea de ryegrass inglés y ryegrass anual con la alfalfa dio como resultado una mala población de la leguminosa, especialmente en los dos primeros cortes. La competencia ejercida por estas dos gramíneas a la alfalfa, se redujo casi completamente, cuando se sembraron en surcos alternos o en la alfalfa establecida. Sea cual fuere el pasto sembrado, la siembra de gramíneas en alfalfa establecida, redujo la competencia entre los pastos asociados. En este ensayo el factor más importante en el establecimiento de las gramíneas, fue el agua disponible en el suelo. Bajo las condiciones del primer experimento el orchoro fue la gramínea que mejor creció en asocio de la alfalfa en todos los métodos de siembra estudiado. La producción promedia de la mezcla varió entre 2600 y 3145 Kg/hect. De forreje seco por corte y la proporción de orchoro entre

    On February 25, 1999, the Oskarshamn-2 NPP experienced a stability event which culminated in diverging power oscillations with a decay ratio of about 1.4. The event was successfully modeled by the TRACE/PARCS coupled code system, and further analysis of the event is described in this paper. The results show very good agreement with the plant data, capturing the entire behavior of the transient including the onset of instability, growth of the oscillations (decay ratio) and oscillation frequency. This provides confidence in the prediction of other parameters which are not available from the plant records. The event provides coupled code validation for a challenging BWR stability event, which involves the accurate simulation of neutron kinetics (NK), thermal-hydraulics (TH), and TH/NK. coupling. The success of this work has demonstrated the ability of the 3-D coupled systems code TRACE/PARCS to capture the complex behavior of BWR stability events. The problem was released as an international OECD/NEA benchmark, and it is the first benchmark based on measured plant data for a stability event with a DR greater than one.

    2013-01-01

    This presentation treats of the NEA/CNRA report of the survey on the review of new reactor application. It indicates that licensing is state specific and that timelines vary from 6 months to 4 years. In addition, review effort and documentation is significant and most states have explicit guidance for the reviews. All states include some form of public participation and regulatory oversight. Next steps include two reports, one on design reviews and another on the construction phase. The author also presented on licensing experience in the United Kingdom. He highlighted the importance of several practices for ensuring a successful project, including: early engagement and communication between applicant and regulatory, sharing of plans between applicant and regulator, establishing and monitoring good metrics on progress and quality for both the applicant and the regulator, identifying 'work streams' and monitoring those streams closely, identifying and addressing risks, ensuring high quality interactions between applicant and regulator, and using dashboards as a way to maintain openness, transparency and trust. He also emphasized the need for engagement at different levels within the organization, including management as necessary

  15. Hydrologic-geochemical modeling needs for nuclear waste disposal systems performance assessments from the NEA perspective

    International Nuclear Information System (INIS)

    Muller, A.B.

    1986-01-01

    Credible scenarios for releases from high level nuclear waste repositories require radionuclides to be mobilized and transported by ground water. The capability to predict ground water flow velocities and directions as well as radionuclide concentrations in the flow system as a function of time are essential for assessing the performance of disposal systems. The first of these parameters can be estimated by hydrologic modeling while the concentrations can be predicted by geochemical modeling. The complementary use of empirical and phenomenological approaches to the geochemical modeling, when effectively coupled with hydrologic models can provide the tools needed for realistic performance assessment. An overview of the activities of the NEA in this area, with emphasis on the geochemical data bases (ISIRS for Ksub(d) data and the thermochemical data base critical review), rock/water interaction modeling (code development and short-courses), and hydrologic-geochemical code coupling (workshop and in-house activities) is presented in this paper from the perspective of probabilistic risk assessment needs.

    In November 2012, the NEA, under the aegis of the Committee on the Safety of Nuclear Installations (CSNI), initiated a joint research project called the Benchmark Study of the Accident at the Fukushima Daiichi Nuclear Power Station (BSAF). Objectives of this project include supporting Fukushima Daiichi decommissioning by analysing accident progression and the current status of the reactors, such as fuel debris distribution in the reactor pressure vessels and primary containment vessels in preparation for fuel debris removal. A second objective of the project is to improve SA (severe analysis) codes through comparisons with data from the Fukushima reactors. So as to enhance communication between analysts and those involved in decommissioning activities, participants in the project have been discussing the remaining uncertainties in relation to understanding the accident and the data needs from the viewpoint of the analysts. Since the accident sequences at the Fukushima Daiichi site include a wide range of phenomena, a phased approach is being applied in this benchmark exercise while awaiting more detailed information on debris examination and other factors. This article provides an overview of the project (scope, input data and boundary conditions, participants (from eight countries), analytical approach - common case and best estimate case) as well as an outline of the project's next phase (BASF phase 2) that begins in June 2015

    Evaluation and assessment is an important part of learning. In evaluation process of learning, written test is still commonly used. However, the tests usually do not following-up by further evaluation. The process only up to grading stage not to evaluate the process and errors which done by students. Whereas if the student has a pattern error and process error, actions taken can be more focused on the fault and why is that happen. NEA procedure provides a way for educators to evaluate student progress more comprehensively. In this study, students’ mistakes in working on some word problem about linear programming have been analyzed. As a result, mistakes are often made students exist in the modeling phase (transformation) and process skills (process skill) with the overall percentage distribution respectively 20% and 15%. According to the observations, these errors occur most commonly due to lack of precision of students in modeling and in hastiness calculation. Error analysis with students on this matter, it is expected educators can determine or use the right way to solve it in the next lesson.

  18. El malestar en la psicopatología contemporánea

    Luciane Loss Jardim

    Full Text Available Resumen: El objetivo del artículo fue presentar una lectura, orientada por el psicoanálisis, acerca del malestar en el campo de la psicopatología contemporánea. Hace mucho tiempo que la psiquiatría mantenía el sueño de encontrar los marcadores biológicos para explicar los comportamientos humanos y sus desvíos, y ahora ganó nueva inversión a partir del nuevo plan estratégico del Instituto Nacional de Salud Mental (NIMH, su sigla en inglés, que si por un lado incentiva el progreso de la ciencia, por otro, plantea un reduccionismo organicista. Sin tomar la posición opuesta, es decir, la de un puro psicologismo de los trastornos mentales o una negación de los factores biológicos en la psicopatología, en este trabajo se plantea una discusión acerca del tema señalando una posición clínica, ética y epistemológica en el abordaje del sufrimiento psíquico. Se concluyó con una aportación del psicoanálisis para el campo de la psicopatología y la práctica en salud mental.

  19. Geopolítica contemporánea desde la postsegunda guerra

    Full Text Available El presente artículo recoge parte de una investigación sobre la visión global geopolítica en el mundo, donde se pretende resaltar lo esencial del Poder y la Política contemporánea. En este esfuerzo teórico empírico de revisión documental y análisis crítico-reflexivo están implícitos las racionalidades geopolíticas de la EraModerna, particularmente la Doctrina Monroe y Wilsoniana que condujeron la política internacional de los Estados Unidos desde el siglo XIX, así como las diversas Doctrinas Geopolíticas y Geoestratégicas puestas en funcionamiento en la Postsegunda guerra, en un contexto de multipolaridad y bipolaridad en los primeros nueve decenios del siglo XX, hasta la unipolaridad en la última década de este siglo. Tras el análisis y correlación se llega a la conclusión que estas doctrinas geopolíticas modificaron el Poder y la Política a escala mundial y conformaron nuevos bloques de poder, guerras, alianzas y reconfiguraciones del poder mundial, bajo su égida imperial.

    2002-01-01

    Full Text Available El presente artículo tiene el propósito de reflexionar sobre los cambios que las nuevas tecnologías de comunicación introducen en los procesos de creación de las identidades contemporáneas. Estas nuevas identidades se construyen tanto por pertenencia a un espacio social, como por referencia simbólica al universo de imágenes mass mediáticas con las que interactúa cotidianamente. En este nuevo escenario: ¿Qué tipos de identidades se están generando? Este ensayo se centra en el debate sobre la homogeneización o la diversificación de las identidades, que se escenifican en tres imágenes contrastantes: las masas, los superindividuos y las tribus. A través de ellas se pueden apreciar los riesgos que representa la dramatización radical de cada una para la construcción de la identidad, y el equilibrio necesario en la relación con la diferencia y la alteridad.

    2016-01-01

    Full Text Available El objetivo de este texto es analizar la relevancia de la transparencia en el ámbito de la sociedad contemporánea, puntualizando que su reconocimiento como política pública ha implicado que se vincule a formas de poder con apertura y publicidad restringidos, hasta estructurarse con los valores y prácticas de la democracia moderna, como medio que hace posible la vigencia del derecho de acceso a la información, combinando oportunidades y restricciones de carácter institucional. La hipótesis del trabajo es que la transparencia controla al poder del Estado y sin embargo, no se explica por sí misma, sino en relación con el secreto y desde que la publicidad coadyuva a que los ciudadanos accedan, conozcan y evalúen la información que las oficinas gubernamentales producen, entendida desde una perspectiva conceptual de políticas públicas. El trabajo utiliza los métodos de interpretación y exposición para generar conocimiento teórico normativo. Las conclusiones se relacionan con la utilidad de la transparencia para institucionalizar un poder abierto, accesible, público y responsable.

    2012-01-01

    For regulatory authorities, it is important to verify the adequacy of ageing management methods applied by the licensees, based on reliable technical evidence. In order to achieve that goal, 14 NEA member countries joined the SCAP (Project) in 2006 to share knowledge and three more countries joined during the course of the project. The project focused on two important safety issues, the stress corrosion cracking (SCC) and the degradation of cable insulation, due to their relevance for plant ageing assessments and their implication on inspection practices. The commendable practices identified in the project are intended to strengthen technical approaches to optimize ageing management in the areas of SCC and cable ageing. The SCAP SCC and Cable data- and knowledge bases provided extensive information to benefit all stakeholders in designing, constructing, operating and regulating Nuclear Power Plants and also provide commendable practices applicable to new reactors. The paper presents the product of SCAP work resulting from 4 years of technical interactions and shared knowledge from all participants from June 2006 to June 2010. (author)

    The two-day workshop held at the OECD Headquarters in Paris on 7-8 July 2015, brought together some of the leading experts in the field of nuclear fission research, development and demonstration. The purpose was to launch the NEA Nuclear Innovation 2050 Initiative, aiming, after a first survey phase, at producing a road-map of main priority research programs and infrastructures necessary to support the role nuclear energy may play in the low carbon power sector of the future. This might then further lead to some ad-hoc co-operation frameworks that help to effectively implement key priorities coming out of the road-mapping. The workshop was organised into the following five sessions: 1 - Opening session on NI2050: vision and main objectives; 2 - National presentations on nuclear fission research and innovation activities (programs, infrastructures, budgets); 3 - Presentations on some existing international nuclear fission road-maps and co-operation frameworks; 4 - Defining the way forward for NI2050: survey, road-mapping and priorities and co-operation; 5 - Open discussion.

    The long history of operating experience with pressurized water reactors has indicated that the steam generators are of primary importance in nuclear power plant design and operation; this is furthermore confirmed by analyzing the data of the Incident Reporting System (IRS). It is for this reason that the OECD/NEA Committee on the Safety of Nuclear Installations organizes, in cooperation with UNIPEDE, a Specialist Meeting on 'Operating Experience with Steam Generators'. This Specialist Meeting, held in Brussels, Belgium, in September 1991, is hosted by the Belgian Government and AIB-Vincotte Nuclear. In addition to being a follow-up to the October 1984 meeting (organized by the CSNI and UNIPEDE in Stockholm, Sweden), this Meeting reviews the current state-of-the-art of steam generator technology thus providing a forum for the exchange of related experience in operation, inspection, maintenance, repair, modifications, replacement, and licensing requirements pertaining to steam generators. Forty-seven papers are presented in eight sessions entitled: Operating Experience (two sessions), Structural Integrity and Licensing Issues, Analysis and Prediction of Degradation Mechanisms, Inservice Inspection Methods, Preventive and Corrective Actions (two sessions) and Replacement of Steam Generators. There are furthermore two panel sessions entitled 'Observed Degradation Mechanisms and Licensing Positions', and 'Inspection, Repair and Replacement Strategies'. These proceedings consist of a compilation of the papers presented at the Meeting, which is attended by more than one hundred and fifty participants from fifteen countries and several international organisations.

    1980-01-01

    After various introductory statements on current occupational radiation exposure trends in nuclear facilities, the authors briefly discuss the problems involved in the application of the ICRP principle of optimization of radiological protection to the design and, in particular, the operation of nuclear plants, with the aim of comparing present exposure trends. To assemble an adequate data base for supporting the technical studies required to optimize radiological protection, the OECD Nuclear Energy Agency and the International Atomic Energy Agency have launched a survey aimed at collecting information on the levels and trends of occupational radiation exposure in the nuclear industry. The features of this study, based on the answers of NEA/IAEA Member States to a questionnaire, are described. The first results of the survey, regarding the situation and time trends of the average individual dose equivalents and collective dose equivalents for different plant types and for several countries, are also given. A preliminary analysis of the data collected allows certain considerations to be made relating to the influence of size, age and plant type, as well as of different national practices in plant operation and maintenance.

    1999-10-01

    Full Text Available Este ensaio visa propor uma reflexão sobre as mudanças na sensibilidade musical no mundo ocidental neste fim de século. As profundas transformações na tecnologia da produção musical ocorridas nas últimas décadas provocaram uma alteração dramática do lugar que a música ocupa na sociedade e também para o indivíduo. Interpreto o impacto dessas mudanças através de quatro elementos de análise profundamente interrelacionados: a tecnologia de gravação e reprodução, a execução musical, a recepção do produto musical e as subculturas musicais que condicionam as opções de uma vasta gama de consumidores de música, jovens e velhos. Na tentativa de construir uma sensibilidade musical deveras pluralista, procurei ilustrar esses argumentos com exemplos musicais retirados dos estilos mais diversos: eruditos, tradicionais, populares, massificados, folclóricos, ritualizados, etc. Dialogo também com teorias da música e da cultura contemporânea que cobrem um amplo eixo da Musicologia e da Etnomusicologia, de Béla Bártok, Adorno e Benjamin a John Blacking, Jacques Attali, Jean Baudrillard, Simon Frith, Lawrence Kramer, entre outros.

    The Forum on Stakeholder Confidence (FSC) was created under a mandate from the OECD Nuclear Energy Agency (NEA) Radioactive Waste Management Committee (RWMC) to facilitate the sharing of international experience in addressing the societal dimension of radioactive waste management. It explores means of ensuring an effective dialogue with the public, and considers ways to strengthen confidence in decision-making processes. The Forum was launched in August 2000 and completed its first phase in 00 . Major findings and principles for action were published under the title of 'Learning and Adapting to Societal Requirements'. Activities of the FSC were also reported at Valdor 2003. In the second mandate of the FSC, there is continued use of a variety of tools and formats to allow dialogue among stakeholders in an atmosphere of mutual trust: national workshops and community visits, topical sessions, and desk and interview studies. In Phase II, the FSC is exploring: the link between research, development and demonstration and stakeholder confidence; cultural and organisational changes in RWM institutions; the role of media relations and outreach opportunities; tools and processes to help society prepare and manage decisions through stakeholder involvement; and increasing the value of waste management facilities to local communities. Workshops have been held in Germany and Spain. A large set of publications makes both Phase I and Phase II findings widely available.

    On February 25, 1999, the Oskarshamn-2 NPP experienced a stability event, which culminated in diverging power oscillations with decay ratio greater than 1.3. The event was successfully modeled by TRACE/PARCS coupled code system and the details of the modeling and solution are described in the paper. The obtained results show excellent agreement with the plant data, capturing the entire behavior of the transient including onset of instability, growth of oscillation (decay ratio) and the oscillation frequency. The event allows coupled code validation for BWR with a real, challenging stability event, which challenges accuracy of neutron kinetics (NK), thermal-hydraulics (TH) and TH/NK coupling. The success of this work has demonstrated the ability of 3-D coupled code systems to capture the complex behavior of BWR stability events. The problem is released as an international OECD/NEA benchmark, and it is the first benchmark based on measured plant data for a stability event with a DR greater than one. Interested participants are invited to contact authors for more information. (author)

    Full Text Available Pensando sobre o sofrimento associado à violência, este texto busca levantar questões sobre a construção social e histórica da vítima e a extensão que essa figura adquire na sociedade contemporânea como legitimação moral de demandas sociais. A construção da vítima é pensada como forma de conferir reconhecimento social ao sofrimento, circunscrevendo-o e dando-lhe inteligibilidade. O campo da saúde mental ocupa um lugar importante nesse processo, através da delimitação, pela Psiquiatria, do Transtorno de Estresse Pós-Traumático (TEPT como referência para o tratamento de vítimas de violência, constituindo um foco privilegiado para essa reflexão. Trata-se de localizar a figura da vítima na lógica social que a engendra, indagando sobre a gramática dos conflitos que fundamentam sua construção e, assim, problematizar os usos que a noção de vítima enseja para legitimar ações sociais e políticas.

    Full Text Available Com base em entrevistas realizadas a homens e mulheres com mais de 65 anos de idade residentes em Portugal, procura-se elaborar um retrato do que significa ser velho e de qual o impacto do processo de envelhecimento na vida e na identidade da pessoa idosa. Partindo do pressuposto de que, não obstante a maior regulação da idade na sociedade contemporânea, existe grande diversidade nas formas de viver a velhice, mobiliza-se uma perspectiva microssociológica de análise, na primeira pessoa, dos discursos sobre o envelhecimento. Além de diferenças de gênero e de estatuto social, a população idosa revela um relativo conformismo com a velhice, enquanto algo que é natural. Porém, algumas dimensões surgem como problemáticas para a identidade do idoso: o declínio do corpo e da saúde, a sexualidade, a perda de atividade, o isolamento e a discriminação social são dimensões particularmente relevantes para conceituar a pessoa idosa como ator reflexivo e portador de reflexividade.

    Full Text Available El artículo presenta una mirada retrospectiva a la línea de Investigación en Jóvenes y Culturas Juveniles del IESCO (DIUC entre 1998-2004. Para ello, se observan las preguntas de partida, los ejes de la reflexión y sus resultados. A lo largo del período observado se produce una pérdida de seguridad en la comprensión de los sujetos jóvenes desde lógicas descriptivas, y se pasa más bien a observar los procesos de subjetivación juvenil. Con base en ello, se caracteriza el conocimiento producido por la línea como una experiencia parcial, localizada, corporeizada y crítica de los estudios de juventud.

A pele é comumente afetada, mas raramente o couro cabeludo. Dois casos de sarcoidose com lesões no couro cabeludo são relatados: o primeiro, em paciente negra apresentando áreas de alopecia no couro cabeludo associada a outras lesões cutâneas; e o segundo, em paciente branca, portadora de sarcoidose pulmonar, com alopecia como manifestação cutânea isolada. A sarcoidose de couro cabeludo merece especial atenção, pois nos pacientes com essa forma de lesão cutânea existe alta incidência de acometimento sistêmico.Sarcoidosis is a multi-system granulomatous disease that generally affects the respiratory tract and hilar lymph nodes. The skin is also commonly involved, although cutaneous sarcoidosis on the scalp is rare. Two cases of scalp sarcoidosis are reported: the first presented with patchy alopecia, cutaneous sarcoidosis and also systemic disease in a black patient; the second case is related to an uncommon presentation with alopecia as the single cutaneous manifestation in a Caucasian patient with pulmonary sarcoidosis. Scalp sarcoidosis deserves special attention because there is a high incidence of other systemic lesions with this cutaneous manifestation, thus a careful investigation should be performed in these patients.

    Full Text Available El centenario de la Gran Vía madrileña se ha convertido en la oportunidad de conocer con mayor detalle la mayoría de los elementos más significativos, desde el punto de vista de la arquitectura, que jalonan esta arteria, producto de la última gran reforma interior acometida en la ciudad de Madrid. En apenas veinte años, se yerguen los últimos ejemplos de la arquitectura ecléctica historicista, para pasar de un salto como pocas veces en nuestra historiografía arquitectónica, a la construcción del posiblemente mejor ejemplo de arquitectura racionalista, el Edificio Capitol, acompañado de algunos destellos de arquitectura moderna que, tras el traumático paréntesis de la Guerra Civil y la primera posguerra, se verán acompañados por elementos singulares de una arquitectura en búsqueda de un camino sin sentido, promovida por el final de una generación de arquitectos. Esta sensación de aceleración y freno se liga a algunos de los nombres más destacados de la arquitectura española de los primeros dos tercios del siglo XX: Palacios, Anasagasti, Gutiérrez Soto, Fernández-Shaw, Muguruza, Feduchi o Eced entre otros. Este artículo pretende analizar el papel jugado por la Gran Vía madrileña en cuanto a escenario de transformación de nuestra arquitectura contemporánea, así como su papel de faro hasta el despegar que se produce con los nuevos arquitectos cuyo talento es reconocido desde finales de los años 50 hasta nuestros días. El nuevo lenguaje arquitectónico surgido en las décadas de los años veinte y treinta, y mostrado como en pocos entornos en la Gran Vía, se liga necesariamente a elementos de transformación social, económica y cultural que se traducen en nuevas necesidades y nuevas tipologías edificatorias, en nuevos usos derivados de demandas y transformaciones que cambian nuestra Historia contemporánea, acompañado de un nuevo lenguaje arquitectónico, que por un breve momento, nos situó a la par de las nuevas

El interés en innovar, a través de diferentes recursos tecnológicos, surge como consecuencia de la dificultad que presentan los estudiantes para trabajar con diferentes modelos físicos. La propuesta desarrollada complementa el estudio de un modelo físico a través de la aplicación de dos programas que se obtienen en línea. Uno de ellos permite diseñar lecciones, las cuales pueden ser recorridas por los estudiantes según sus respuestas. Su uso es interesante porque facilita la personalización del aprendizaje a través de una herramienta accesible al docente y puede ser incorporada como SCORM o ser utilizada en forma independiente. El otro programa, diseñado en lenguaje Java, permite procesar videos codificados. Si bien en este trabajo se muestra un ejemplo aplicado a la Física universitaria, ambas herramientas pueden utilizarse en distintas situaciones didácticas y en diferentes niveles educativos. Con la implementación de las TIC al aula convencional no se pretende reemplazar recursos didácticos eficaces, pero sí enriquecerlos adaptándolos a las necesidades cognitivas de los estudiantes en acuerdo a un determinado contexto de formación.

    In the present paper, the activities of the AZTLAN Platform Fast Reactor Group on the OECD/Nea Benchmark will be described. The main objective of these activities is to test the group staff and capabilities as well as the domestic code reliability by putting them into test in this exercise with different institutions from around the world. Six different core configurations were treated; these are described in two different versions of the Benchmark document. The main tools used by the group were the Finnish stochastic Monte Carlo code Serpent for full core calculations and macroscopic Cross Sections (X S) generation, and the domestic deterministic code AZNHEX for full core calculations. Different calculations were performed, such as full core calculations under nominal conditions, with control rods fully and partially inserted and with the sodium voided in the active zone as well as different reactivity shift values due to various conditions of radial and axial expansion of the fuel elements and structural material. The results obtained in the full core calculations and most of the reactivity shift calculations obtained by our group were indeed comparable to the ones obtained by different institutions when using similar methodologies. Given these favorable results it can be said that the main objective was met and the group showed their capabilities, as well as its possibility to collaborate with other institutes, placing Mexico in a good position in fast reactor analysis. Future work will continue with the calculations not yet treated and with the new core specifications on the new versions of the Benchmark document. (Author)

    Highlights: • A unique PWR spent fuel pool experimental project is analytically investigated. • Predictability of fuel clad ignition in case of a complete loss of coolant in SFPs is assessed. • Computer codes reasonably estimate peak cladding temperature and time of ignition. - Abstract: The OECD/NEA Sandia Fuel Project provided unique thermal-hydraulic experimental data associated with Spent Fuel Pool (SFP) complete drain down. The study conducted at Sandia National Laboratories (SNL) was successfully completed (July 2009 to February 2013). The accident conditions of interest for the SFP were simulated in a full scale prototypic fashion (electrically heated, prototypic assemblies in a prototypic SFP rack) so that the experimental results closely represent actual fuel assembly responses. A major impetus for this work was to facilitate severe accident code validation and to reduce modeling uncertainties within the codes. Phase I focused on axial heating and burn propagation in a single PWR 17 × 17 assembly (i.e. “hot neighbors” configuration). Phase II addressed axial and radial heating and zirconium fire propagation including effects of fuel rod ballooning in a 1 × 4 assembly configuration (i.e. single, hot center assembly and four, “cooler neighbors”). This paper summarizes the comparative analysis regarding the final destructive ignition test of the phase I of the project. The objective of the benchmark is to evaluate and compare the predictive capabilities of computer codes concerning the ignition testing of PWR fuel assemblies. Nine institutions from eight different countries were involved in the benchmark calculations. The time to ignition and the maximum temperature are adequately captured by the calculations. It is believed that the benchmark constitutes an enlargement of the validation range for the codes to the conditions tested, thus enhancing the code applicability to other fuel assembly designs and configurations.

  8. OECD/NEA International Common Cause Failure Data Exchange (ICDE) project - insights and lessons learnt

    Events initiated by common-cause-failure (CCF) can significantly affect the availability and reliability of nuclear power plant safety systems. In recognition of this, CCF data are systematically collected and analysed in the International Common-Cause Data Exchange (ICDE) Project, which was initiated in August 1994. Since April 1998, the NEA has formally operated the project. Currently eleven countries participate in the project. The ICDE collects all events where two or more identical, redundant components of a group, fulfilling the same function, have failed or were impaired due to a shared cause (ICDE events). Complete CCFs, i. e. failure of all identical, redundant components in the group due to a shared cause are an important subset of the collected data. Currently, data exchange and analysis covers the following components: centrifugal pumps, diesel generators, motor-operated valves, safety and relief valves, check valves, reactor protection system components (level measurement, control rod drives, etc), circuit breakers, and batteries. The main findings of the ICDE reports issued by 2005 show averaged over all components that about two thirds of all complete CCF events involve faulty actions by plant personnel and contractors. The single largest contribution is from faulty testing and maintenance work due to deficient and/or incomplete procedures. Other important causes are insufficient testing and requalification of components or systems after maintenance, repair, modifications or backfitting work, as well as operator errors of commission. The probability that a reported ICDE event is a complete CCF decreases strongly with increasing number of redundant components, demonstrating the effectiveness of redundancy as a powerful defence against CCFs. However, complete CCFs cannot be completely prevented by high redundancy only. (orig.)

    2013-01-01

    Within licensing procedures there is the incentive to replace the conservative requirements for code application by a 'best estimate' concept supplemented by an uncertainty analysis to account for predictive uncertainties of code results. Methods have been developed to quantify these uncertainties. The Uncertainty Methods Study (UMS) Group, following a mandate from CSNI (Committee on the Safety of Nuclear Installations) of OECD/NEA (Organization for Economic Cooperation and Development / Nuclear Energy Agency), has compared five methods for calculating the uncertainty in the predictions of advanced 'best estimate' thermal-hydraulic codes. Most of the methods identify and combine input uncertainties. The major differences between the predictions of the methods came from the choice of uncertain parameters and the quantification of the input uncertainties, i.e. the wideness of the uncertainty ranges. Therefore, suitable experimental and analytical information has to be selected to specify these uncertainty ranges or distributions. After the closure of the Uncertainty Method Study (UMS) and after the report was issued comparison calculations of experiment LSTF-SB-CL-18 were performed by University of Pisa using different versions of the RELAP 5 code. It turned out that the version used by two of the participants calculated a 170 K higher peak clad temperature compared with other versions using the same input deck. This may contribute to the differences of the upper limit of the uncertainty ranges. A 'bifurcation' analysis was also performed by the same research group also providing another way of interpreting the high temperature peak calculated by two of the participants. (authors)

  10. Improving nuclear regulation. NEA regulatory guidance booklets volumes 1-14

    International Nuclear Information System (INIS)

    2011-01-01

    A common theme throughout the series of NEA regulatory guidance reports, or 'green booklets', is the premise that the fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear facilities are continuously maintained and operated in an acceptably safe manner. In meeting this objective the regulator must bear in mind that it is the operator that has responsibility for safely operating the nuclear facility; the role of the regulator is to assess and to provide assurance regarding the operator's activities in terms of assuming that responsibility. The full series of these reports was brought together in one edition for the first time in 2009 and was widely found to be a useful resource. This second edition comprises 14 volumes, including the latest on The Nuclear Regulator's Role in Assessing Licensee Oversight of Vendor and Other Contracted Services. The reports address various challenges that could apply throughout the lifetime of a nuclear facility, including design, siting, manufacturing, construction, commissioning, operation, maintenance and decommissioning. The compilation is intended to serve as a knowledge management tool both for current regulators and the new nuclear professionals and organisations entering the regulatory field. Contents: Executive Summary; Regulatory Challenges: 1. The Role of the Nuclear Regulator in Promoting and Evaluating Safety Culture; 2. Regulatory Response Strategies for Safety Culture Problems; 3. Nuclear Regulatory Challenges Related to Human Performance; 4. Regulatory Challenges in Using Nuclear Operating Experience; 5. Nuclear Regulatory Review of Licensee Self-assessment (LSA); 6. Nuclear Regulatory Challenges Arising from Competition in Electricity Markets; 7. The Nuclear Regulatory Challenge of Judging Safety Back-fits; 8. The Regulatory Challenges of Decommissioning Nuclear Reactors; 9. The Nuclear Regulator's Role in Assessing Licensee Oversight of Vendor and Other Contracted Services

Este ensayo se centra en el debate sobre la homogeneización o la diversificación de las identidades, que se escenifican en tres imágenes contrastantes: las masas, los superindividuos y las tribus. A través de ellas se pueden apreciar los riesgos que representa la dramatización radical de cada una para la construcción de la identidad, y el equilibrio necesario en la relación con la diferencia y la alteridad.The present article has as its purpose to reflect on some of the changes that new communicative technologies introduce in processes of creation of contemporary identities. This new identities are constructed as much by their belonging to a social space, as by their symbolic reference to the universe of mass media images with which it interacts daily. In this new scenario, what types of identities are being generated? This essay is centered on the debate between the homogenization or the diversification of identities, which are portrayed in three contrasting images: the masses, the superindividuals, and the tribes. Through them one can appreciate the risks represented in the radical dramatization of each one of them for the contruction of identity, and the necessary equilibrium in the relation with difference and alterity.

    Full Text Available Este artigo aborda a comunicação corporativa na sociedade contemporânea, ressaltando as transformações do capitalismo na virada do milênio, a revolução da tecnologia da informação e a emergência da sociedade de controle, a partir de diferentes autores como Castells, Deleuze, Lazzarato, dentre outros.   Discutimos a relação entre informação e sociedade, o conceito de informação e sua importância para a atualidade, chamando a atenção para a relação entre valor, informação e cultura. Ao trazer a reflexão deleuziana sobre conceito de sociedade de controle como decorrente da crise das instituições e do avanço das tecnologias informacionais, e de Lazzarato, sobre a noopolítica, destacamos que o trabalho das corporações deve antecipar a demanda, fazendo-a acontecer.          Frente às exigências de rapidez, eficiência e o endividamento contínuo na atualidade, apontamos a comunicação corporativa como aquela que vem tomar a necessidade de criação de um público, de uma clientela, de uma demanda. Por fim, destacamos que as organizações que aprendem e a educação corporativa são algumas respostas às exigências da contemporaneidade, enfatizando a comunicação corporativa como uma das ferramentas que as empresas se valem na busca de sobrevivência e sucesso.

    Full Text Available El pasado diciembre se cumplieron 50 años de la formación del grupo Superstudio. El aniversario se presenta como la ocasión para realizar la revisión de algunas ideas que el grupo planteó a través de la obra teórica gráfica del Monumento Continuo. A través de tres diferentes formatos Superstudio representó un trabajo con connotaciones claramente visionarias, que planteaba la propuesta de un objeto al límite de las posibilidades de la arquitectura. Las tres obras se podrían definir como ensayos entrópicos por: la ausencia de una organización sistemática y lineal de las tres representaciones; la composición, que en el caso de las tres obras expresaría la condición de fragmentariedad; la metamorfosis, el proceso continuo en el cual el monumento, el paisaje, la historia sufren incesantes transformaciones; la inestabilidad e indeterminación de los conceptos de memoria, lugar, forma, función, proporcionan un mayor grado de libertad para actuar dentro de sus bases nunca definitivas. La intención del artículo es establecer cómo la obra facilita instrumentos para una crítica contemporánea, el entendimiento del proceso de continuidad y discontinuidad del tiempo moderno y cómo muchas cuestiones actuales se abrieron justamente en este periodo, que como una bisagra sigue uniendo y agitando ambas duradas.

    In 2003 with a foreseen duration of four years. The main objective of this new phase is to extend the existing critically reviewed database for elements of relevance in radioactive waste management, paying attention to the needs of the various national programmes. Following the decision by the Project Management Board (integrated by representatives of 16 organisations with responsibilities in radioactive waste management in 12 OECD member countries) the elements contemplated in this new phase are Th, Sn and Fe, with a higher priority being allocated to inorganic species and compounds. In addition to the corresponding review teams for these elements, an additional expert team has been constituted to prepare guidelines for the evaluation of thermodynamic data for solid solutions. As was the case in TDB Phase II, the basic project review methodology remains unaltered in TDB III. The Figure illustrates the relationship between the various TDB bodies, with an International Organisation, the OECD NEA, acting as Project Coordinator and linking the independent scientific teams and the project governing bodies. This organizational paradigm has proven successful with the recent completion of the five Phase II Reviews (Update, Ni, Se, Zr and Organic Ligands). The review and expert team activities were started in 2004 (except for Fe, being started in 2005) following an initiation stage. This preliminary stage was designed in order to tailor the team compositions to the existing literature for each element. The first reviews stemming from TDB III are scheduled to appear in published form in 2007. The successful completion of these objectives will add three further reports to the current series of nine volumes (dealing with the chemical thermodynamics of U, Np, Pu, Am, Tc, Ni, Se, Zr and compounds and complexes of these elements with oxalate, citrate, EDTA and isa).

    2017-10-01

    The Intrepid mission concept calls for phased deployment of a fleet of small highly autonomous rendezvous spacecraft designed to characterize the evolution, structure and composition of dozens of Near-Earth Asteroids (NEAs). Intrepid represents a marked departure from conventional solar system exploration projects, where a single unique and complex spacecraft is typically directed to explore a single target body. In contrast, Intrepid relies on the deployment of a large number of autonomous spacecraft to provide redundancy and ensure that the project goals are achieved at a small fraction of the cost of typical missions.The Intrepid science goals are threefold: (1) to understand the evolutionary processes that govern asteroid physical, chemical and dynamical histories and relate these results to solar system origins and evolution; (2) to facilitate impactor deflection scenarios for planetary defense by statistically characterizing relevant asteroid physical properties; (3) to quantify the presence and extractability of potentially useful resources on a large sample of asteroids. To achieve these goals, the baseline architecture includes multiple modular instruments including cameras, spectrometers, radar sounders, and projectiles that could interact with the target asteroid. Key questions to be addressed are: what is the total quantity of water in each object? How is the water incorporated? Are organics present? What is the asteroid physical structure? How would the object respond to impact/deflection?We have begun development of a miniature infrared point spectrometer, a cornerstone of the Intrepid payload, covering both shortwave infrared (SWIR) and mid-infrared (MIR) spectral bands. The spectrometer is designed with a compact 2U form-factor, making it both relevant to Intrepid and implementable on a CubeSat. The combination of SWIR and MIR in a single integrated instrument would enable robust compositional interpretations from a single dataset combining both

    International Nuclear Information System (INIS)

    2003-01-01

    Incident reporting has become an increasingly important aspect of the operation and regulation of all public health and safety-related industries. Diverse industries such as aeronautics, chemicals, pharmaceuticals and explosives all depend on operating experience feedback to provide lessons learned about safety. The Incident Reporting System (IRS) is an essential element of the system for feeding back international operating experience for nuclear power plants. IRS reports contain information on events of Safety significance with important lessons learned. These experiences assist in reducing or eliminating recurrence of events at other plants. The IRS is jointly operated and managed by the Nuclear Energy Agency (NEA), a semi-autonomous body within the Organisation for Economic Co-operation and Development (OECD), and the International Atomic Energy Agency (IAEA). It is important that sufficient national resources be allocated to enable timely and high quality reporting of events important to safety, and to share these events in the IRS database. The first report, which covered the period July 1996 - June 1999, was widely acclaimed and encouraged both agencies to prepare this second report in order to highlight important lessons learned from around 300 events reported to the IRS for the period July 1999 - December 2002. Several areas were selected in this report to show the range of important topics available in the IRS. These include different types of failure in a variety of plant systems, as well as human performance considerations. This report is primarily aimed at senior officials in industry and government who have decision-making roles in the nuclear power industry

Parte da constatação de que, se se observa, de um lado, um crescimento na complexidade lógica do pensamento coloquial verbalizado, de outro, percebe-se uma ausência de competência nas operações intelectuais de análise dos processos racionais a ele subjacentes. Ou seja, a racionalidade contemporânea, alimentada pelos processos e produtos de conhecimento gerados através do pensamento abstrato e dedutivo do campo técnico-científico, comunicar-se-ia com a sociedade de maneira naturalizada, sob forma de representação social e, portanto, eivada de aportes ideológicos, de irracionalidades e/ou racionalizações acríticas. Visa-se refletir, então, sobre como subsidiar a superação de obstáculos à universalização do pleno exercício da razão e/ou da hermenêutica da racionalidade, instrumentalizando contrapontos aos impedimentos gerados pela ignorância ou pelas negatividades ou pelos núcleos dogmáticos do pensamento.

    2017-09-01

    Following the release and initial testing period of the NEA's Nuclear Data Sensitivity Tool [1], new features have been designed and implemented in order to expand its uncertainty analysis capabilities. The aim is to provide a free online tool for integral benchmark testing, that is both efficient and comprehensive, meeting the needs of the nuclear data and benchmark testing communities. New features include access to P1 sensitivities for neutron scattering angular distribution [2] and constrained Chi sensitivities for the prompt fission neutron energy sampling. Both of these are compatible with covariance data accessed via the JANIS nuclear data software, enabling propagation of the resultant uncertainties in keff to a large series of integral experiment benchmarks. These capabilities are available using a number of different covariance libraries e.g., ENDF/B, JEFF, JENDL and TENDL, allowing comparison of the broad range of results it is possible to obtain. The IRPhE database of reactor physics measurements is now also accessible within the tool in addition to the criticality benchmarks from ICSBEP. Other improvements include the ability to determine and visualise the energy dependence of a given calculated result in order to better identify specific regions of importance or high uncertainty contribution. Sorting and statistical analysis of the selected benchmark suite is now also provided. Examples of the plots generated by the software are included to illustrate such capabilities. Finally, a number of analytical expressions, for example Maxwellian and Watt fission spectra will be included. This will allow the analyst to determine the impact of varying such distributions within the data evaluation, either through adjustment of parameters within the expressions, or by comparison to a more general probability distribution fitted to measured data. The impact of such changes is verified through calculations which are compared to a `direct' measurement found by

    Full Text Available INTRODUCCIÓN. La fístula faringocutánea se detecta clínicamente por la aparición de saliva simultáneamente con la deglución. Es muy frecuente en el posoperatorio de las laringectomías totales, y puede aparecer espontáneamente por dehiscencia de la sutura faríngea a causa de los movimientos deglutorios del paciente, o bien puede acompañar a una infección o necrosis. MÉTODOS. Se realizó un estudio ambispectivo, descriptivo, sobre el comportamiento de las fístulas faringocutáneas en el Servicio de Cirugía Oncológica Cervicofacial de Hospital Universitario «Vladimir Ilich Lenin», en Holguín. El universo de estudio estuvo constituido por todos los pacientes operados con laringectomía total en el período del 2003 al 2008. Fueron 158 pacientes en total y a todos se les realizó el cierre manual de la hipofaringe. RESULTADOS. Las fístulas estuvieron presentes en el 5,6 % de los casos. El 77,7 % de los pacientes habían recibido radioterapia antes de la operación y el 66,4 % de éstos tenían traqueostomías en el momento de la intervención quirúrgica. En todos los pacientes con faringostoma se encontró sepsis posquirúrgica y la alimentación oral se comenzó entre los días 10 y 12 en el 88,4 % de los casos. CONCLUSIONES. El amplio predominio de pacientes del sexo masculino está en relación directa con los hábitos tóxicos predominantes en este sexo. La traqueostomía prequirúrgica es aceptada por los cirujanos como factor de riesgo para el desarrollo de la fístula, pero en este estudio no fue significativo. El tiempo de comienzo de la alimentación oral en los pacientes con larigectomías debe oscilar entre los días 10 y 14, nunca antes, pues no existe una cicatrización de la hipofaringe que garantice el paso de los alimentos. Además, de esta forma se evita que aparezcan complicaciones como las fístulas faringocutáneas.INTRODUCTION. The pharyngocutaneous fistula is clinically detected by appearance of saliva

    The Forum on Stakeholder Confidence (FSC) was created under a mandate from the NEA Radioactive Waste Management Committee (RWMC) to facilitate the sharing of international experience in addressing the societal dimension of radioactive waste management. It explores means of ensuring an effective dialogue with the public, and considers ways to strengthen confidence in decision-making processes. The Forum was launched in August 2000, in Paris, with an international workshop. This addressed a variety of topics ranging from evolving participatory democracy, stakeholder identity, and trust in the institutional frarnework, to the role of open dialogue in all aspects of radioactive waste management. Two additional workshops were held in 2001 and 2002, respectively in Finland and Canada. In the Finnish meeting, representatives from all stakeholder groups - from the local to the national level - reviewed the sequence of decisions that ultimately led to the Parliament's approval, in May 2001, of siting a geological repository in the municipality of Eurajoki. The workshop was preceded by an encounter with the municipality representatives, where the values, as well as the policies and the economic standing of the community, were discussed. Feedback was provided to the workshop by experts in public management, strategic decision, community development and social psychology. The Canadian workshop, held in October 2002, allowed to review the recent national experience in the radioactive waste management programme. In March 2001, an agreement was reached between the Government and three communities in southern Ontario to clean up and locally manage radioactive waste from past uranium processing. In June 2002 the Nuclear Fuel Waste Act became law, enabling Canada to move effectively towards a solution for the long-term management of 'spent fuel waste'. At the workshop, three key areas of inquiry were examined: what are the social concerns at play in radioactive waste management; how

    In response to growing interest in the decommissioning of nuclear facilities, the OECD Nuclear Energy Agency set up the Co-operative Programme on Decommissioning in 1985. Its basic scope is to facilitate the exchange of scientific and technical information between major decommissioning projects. Participation in the Programme has expanded significantly over the years to include organisations from 13 countries. Currently, about 60 projects participate in the Programme. The Programme is executed under an agreement between the participating organisations and companies. A progress report is issued every five years on the CPD and includes a brief description of each project. The most recent report is entitled A Decade of Progress. The projects are divided into two groups: reactor projects (60%) and fuel facility projects (40%). A complete list of the different projects and their country of residence can be found in Annex 1. Many of the early projects in the Programme focused on experimental or prototype plants, however, a number of projects for the decommissioning of commercial facilities (power generation, fuel and reprocessing plants) have recently joined the Programme. Limited feedback on concrete clean-up operations has been available until now due to the lengthy time frame of decommissioning projects and the fact that building demolition occurs in the very late stages of the project. Some of the early projects in the Programme are now complete or nearing completion, making available significant data and experience. This experience and lessons learnt can be applied to the further development of decommissioning and dismantling (D and D) clean-up processes. This report aims to supplement the previous NEA report dedicated to decontamination techniques and to provide project engineers and/or project leaders involved in concrete infrastructure clean-up with: - Guidelines for setting up appropriate and adequate strategies, taking into consideration the international

    A total of 70 EXFOR entries for neutron induced experiments, were compiled and transmitted to the other data centres. Forty six (46) of these entries concerned new experiments. More than 600 new entries were compiled into the CINDA database in the same period. The updated CD-ROM version of the CINDA database has once again been distributed. In 2000 the Data Bank compiled ∼100 new data sets from charged particle induced experiments and these are currently undergoing testing before being entered into the EXFOR database. Due to additions to the database structure, a complete re-writing of the loading/retrieval programs (conversion from FORTRAN coding to PERL scripts) and hardware upgrades the loading has been delayed somewhat. Two versions of the JEFF-3.T general-purpose starter file were produced in 2000, following improvements to the evaluations through the correction of format and physics errors. New evaluations are incorporated as they become available (e.g. EFF files) or when changes to the initial recommendations (e.g. for Fission Products and Minor Actinides) are decided based on additional evidence. The validation of the file is ongoing in the form of calculations of a subset of the JEF-2.2 benchmarks. Special emphasis is being put on PWR uranium lattices, since earlier results showed a slight systematic underestimation of the reactivity of these lattices. For the production of the Radioactive Decay Data starter file, comparisons were made between the two libraries recently produced in the UK, UKPADD-6.1 and UKHEDD-2.2, and further evaluations based on NUBASE and ENSDF data. The first version of the JEFF-3.T Decay Data file, containing ∼3700 nuclides, was produced in late 2000 and extensive testing was applied including the development of specific methods for energy balance checks. These have been implemented into the FIZCON code, renamed EFIZCON. The NEA Data Bank has taken an initiative on behalf of the WPEC sub-group concerned with the High Priority

Secondly, the need to increase knowledge about foreign women in Spain is justified: by their number, family regrouping, and the increase of their birth-rate in Spain ... and above all as workers. For this reason, the main results of a study carried out on 304 African women and 330 Latin-American women living in Spain are shown. The third paragraph shows the results of another study carried out in the same region on 77 companies and business organisations that employ women immigrants: the companies questioned show a wide range of opinions on their motives for employing immigrants, on the characteristics of these workers and on the repercussions on the economic sector or on the businessman, if this workforce disappeared.

Por otra parte, el desarrollo tecnológico y el contexto del propio mercado mundial han logrado en poco más de dos siglos lo que la Humanidad no ha gestado en sus más de cuarenta centurias anteriores: que la capacidad de autodestrucción se convierta en uno de los mayores negocios del planeta y en génesis de una de las principales parcelas de aceleración de la capacidad de invención humana.

    Full Text Available Hoy en día, se puede afirmar que se halla plenamente consolidado como objeto historiográfico el mundo de la universidad española en los siglos xix y xx y en particular el profesorado universitario. En particular, el enfoque prosopográfico ya viene siendo una práctica relativamente habitual entre los investigadores que se acercan con algún detenimiento al estudio de la historia del profesorado universitario. La fecunda y ambiciosa iniciativa de elaborar un Diccionario de catedráticos españoles de Derecho (1847-1943 supone un salto cualitativo importante que merece destacarse en ese ámbito. También queremos recordar a continuación el interés que siguen teniendo los escalafones de antigüedad de catedráticos de universidad para un enfoque sociológico del conjunto del profesorado universitario en la época contemporánea, limitado desde luego al cuerpo de los catedráticos.En efecto, tanto el Diccionario como los escalafones adolecen de un «defecto» originario y comprensible ya que tan sólo enfocan el cuerpo de catedráticos. Dejan, pues, de lado no sólo a las «mujeres universitarias» (hasta 1953 ―salvo el caso aislado y no representativo de Emilia Pardo Bazán― que habían logrado ingresar en una universidad como profesoras auxiliares, sino, en general, a todos los profesores no catedráticos. Otra «variable» no contemplada es la de los orígenes sociales del profesorado universitario, a lo que podríamos añadir otros elementos referentes a la «condición universitaria». Desbordamos así la historia universitaria «académica» para ir hacia una historia «social» del profesorado universitario, taller inmenso que sólo puede llevarse a cabo de manera colectiva e interdisciplinar.

    A benchmark of numerical simulations related to the missile impact on reinforced concrete (RC) slabs has been launched in the frame of OECD/NEA/CSNI research program “Improving Robustness Assessment Methodologies for Structures Impacted by Missiles”, under the acronym IRIS. The goal of the research program is to simulate RC structural, flexural and punching, behavior under deformable and rigid missile impact. The first phase called IRIS-2010 was a blind prediction of the tests performed at VTT facility in Espoo, Finland. The two simulations were performed related to two series of tests: (1) two tests on the impact of a deformable missile exhibiting damage mainly by flexural (so-called “flexural tests”) or global response and (2) three tests on the impact of a rigid missile exhibiting damage mainly by punching response (so-called “punching tests”) or local response. The simulation results showed significant scatter (coefficient of variation up to 132%) for both flexural and punching cases. The IRIS-2012 is the second, post-test, phase of the benchmark with the goal to improve simulations and reduce the scatter of the results. Based on the IRIS-2010 recommendations and to better calibrate concrete constitutive models, a series of tri-axial tests as well as Brazilian tests were performed as a part of the IRIS-2012 benchmark. 25 teams from 11 countries took part in this exercise. Majority of participants were part of the IRIS-2010 benchmark. Participants showed significant improvement in reducing epistemic uncertainties in impact simulations. Several teams presented both finite element (FE) and simplified analysis as per recommendations of the IRIS-2010. The improvements were at the level of simulation results but also at the level of understanding of impact phenomena and its modeling. Due to the complexity of the physical phenomena and its simulation (high geometric and material non-linear behavior) and inherent epistemic and aleatory uncertainties, the

    Full Text Available O livro de Lipovetsky é um passeio sobre as novas caracterizações da leveza da vida na sociedade contemporânea. Na edição, os capítulos não foram enumerados. Mas na resenha são. O livro começa com uma boa apresentação de Juremir Machado da Silva, professor da PUC-RS, que dá uma visão panorâmica do pensamento do autor. Capítulo 1 é a introdução das hipóteses, primeiro de hipermodernidade, em seguida a hipótese sobre a busca da leveza. Capítulo 2 é sobre as transformações no padrão de consumo e no comportamento do hiperconsumidor. Capítulo 3 trata do desejo de ter um corpo jovem e saudável, o que é uma voluntária adesão à ditadura do corpo magro e esbelto. Capítulo 4 tem a análise da economia que oferta os produtos para satisfazer o desejo de leveza. Capítulo 5 é uma atualização da análise sobre moda. Capítulos 6 e 7 são sobre o impacto do crescente desejo de leveza  na arte e na arquitetura. Capítulo 8 é uma análise sobre a psicologia das pessoas que buscam a leveza como felicidade, com resultados paradoxais. Capítulo 9 é sobre como o desejo por uma vida mais livre, leve e ética afeta o comportamento dos cidadãos. A ausência de um capítulo conclusivo revela que é difícil analisar um mundo em transição. O autor limitou-se a descrever a busca da leveza como uma nova tendência, com impacto sobre comportamento dos indivíduos e a economia e política da sociedade.

    Full Text Available Una línea de profundización es una estrategia didáctica de trabajo en grupo de docentes y estudiantes de diferentes niveles de formación, que facilita los procesos de enseñanza, aprendizaje, investigación y evaluación en un currículo contextualizado. Esta metodología, fundamentada en el seminario investigativo, y enriquecida con otras estrategias didácticas, brinda un espacio para la creatividad porque permite la integración de docencia, investigación y extensión; es semillero de investigadores al traducir científicamente los hechos cotidianos y es medio para la investigación formativa. Sirve para generar una línea de investigación o puede ocurrir el proceso inverso cuando una línea de profundización surge desde ésta. Esta estrategia es propia del currículo flexible que permite la producción social de conocimiento en el contexto nacional e internacional con metodologías intensivas para fomentar el trabajo autónomo del estudiante y el profesor. Tiene diversidad de ventajas como aprender a traducir científicamente los problemas cotidianos, favorece el desarrollo de competencias, permite trabajar en equipo para cuestionar el conocimiento y solucionar problemas, liga la docencia con la investigación. Como posibles dificultades la permanencia por un periodo corto de algunos estudiantes de pregrado lo que implica mayor esfuerzo del docente, por tanto se sugiere ofrecerla a estudiantes de posgrado que están por períodos más largos.

    Full Text Available Esta investigación aborda el desarrollo de las interacciones de una comunidad en línea. Sigue el modelo propuesto por Garrison, Anderson y Archer (2000, quienes consideran que la presencia social, cognitiva y docente son factores fundamentales para el desarrollo de aprendizajes efectivos en una comunicación mediada por computadora. El artículo analiza el peso que tiene la presencia docente y social en el desarrollo de la presencia cognitiva, entendida ésta como el grado en el cual los participantes de una comunidad en línea son hábiles para construir significado a través de una comunicación sostenida. Se examinaron seis foros de una asignatura del Centro Universitario de los Valles, de la Universidad de Guadalajara, que trabaja desde su creación con un modelo académico apoyado en las tecnologías de la información y la comunicación. Como método se utilizó el análisis cuantitativo de contenido y se aplicó el modelo de codificación para una comunidad de indagación propuesto por Garrison, Anderson y Archer, mediante el cual se codifican los mensajes generados en los foros y se identifica la frecuencia de cada uno de los elementos y sus categorías. Los resultados señalan que la presencia social es la más recurrente, al encontrarse ésta en 92% de los mensajes analizados, pero no es suficiente para el éxito de una comunidad en línea; es sólo la base; se requiere la intervención y guía del docente para favorecer la presencia cognitiva y, con ello, la construcción social del conocimiento.

    Full Text Available Como parte del proceso de evaluación del impacto ambiental ante la puesta en funcionamiento de la planta de pulpa de celulosa Kraft Botnia (actual UPM, se realizaron estudios de línea de base entre los años 2005 y 2007. El diseño de muestreo incluyó tres transectas perpendiculares a la línea de costa, en tres sitios: Nuevo Berlín, Fray Bentos y Las Cañas. Se realizaron estudios de parámetros físico-químicos del agua (nutrientes, sustancias orgánicas, metales, compuestos orgánicos adsorbibles (AOX, dioxinas y furanos, materia orgánica y granulometría del sedimento, estudios biológicos de las comunidades planctónicas, zoobentónicas e ícticas y bioacumulación de dioxinas en peces. El fósforo en la columna de agua presentó en promedio valores por encima de lo recomendado por la normativa nacional, mientras los contaminantes orgánicos (AOX, clorofenoles, ácidos resínicos, fitosteroles, dioxinas y furanos se mantuvieron por debajo de los valores guía recomendados a nivel internacional. Las comunidades planctónicas variaron significativamente entre muestreos, la de peces entre sitios y muestreos, mientras que la de bentos no presentó variaciones significativas espaciales ni temporales. El bagre trompudo (Iheringichthys labrosus es propuesto como especie a sermonitoreada debido a su ubicuidad y abundancia. Este trabajo ofrece una visión general de los estudios de línea de base, destacando la multiplicidad y la periodicidad de los parámetros en dos años de estudio.

    Full Text Available El agua subterránea constituye una fuente relevante de agua dulce necesaria para la vida, el medio ambiente y el desarrollo de los pueblos. Este recurso se caracteriza tanto por su finitud como por su vulnerabilidad, aspectos aparentemente ignorados por el hombre que continúa contaminándolo y alterando sus aptitudes. La demanda mundial de agua dulce ha crecido en correlación con la población mundial, pero el sector agropecuario ha aumentado sensiblemente la explotación de los acuíferos, en particular para riego de cultivos, que insumen el 70 % del total. El objetivo de este trabajo consistió en realizar la caracterización hidroquímica del agua subterránea rural del departamento Villaguay (Entre Ríos y determinar la calidad para los usos rurales, utilizando para ello metodologías estandarizadas para analizarlas y aceptados criterios de evaluación. Los resultados muestran que las aguas se caracterizan como bicarbonatadas en los distritos al este del río Gualeguay, y como sulfatadas al oeste del mismo. La evaluación del agua para bebida animal indica que poseen aptitud buena a regular. En cuanto a calidad del agua para riego, presenta en general ligeras restricciones de uso. Las aguas para las aplicaciones de pesticidas muestran limitantes que requieren la corrección particular del pH y la dureza. Palabras clave: agua subterránea rural; caracterización hidroquímica; calidad para usos agropecuarios.

    Full Text Available Se realizó un estudio randomizado de 75 pacientes con leishmaniasis cutánea ecuatoriana con el fin de determinar el índice terapéutico de una nueva droga oral antileishmania, el ribósido de alopurinol más probenecid. Este agente fue evaluado comparándolo con controles positivos que se trataron con pentostam y con testigos no tratados. Las medidas de las lesiones disminuyeron rápidamente durante la terapia, lo que permitió determinar el porcentaje de cicatrización en los diferentes grupos. En el día 70 se realizó la evaluación de la curación de los pacientes en los diferentes grupos, obteniéndose: alopurinol (1.500 mg/6 h más probenecid (500 mgI6 h por 28 días, dió una curación con lesiones cicatrizadas en 10 (45,5% de los 22 pacientes. Con pentostam (20 mg Sblkgtdía, IM por 20 días se obtuvo una curación en 28 pacientes siendo esto el 100% de cicatrización. El grupo de no tratamiento presentó un porcentaje muy elevado de curación espontánea en 9 (75,0% de los 12 pacientes. Todos los pacientes con tratamiento fallido o recidivas recibieron posteriormente tratamiento con pentostam. Este estudio sugiere que el ribósido de alopurinol más probenecid no es una droga con mayor eficacia contra la leishmaniasis cutánea ecuatoriana.

    2010-10-01

    Full Text Available Los cursos en línea son una estrategia empleada por las instituciones de educación superior para incorporar las tecnologías de la información y la comunicación en los procesos de enseñanza-aprendizaje, contribuyendo, a su vez, a desarrollar las competencias tecnológicas y de autogestión del aprendizaje que los estudiantes requieren para su ejercicio profesional y para la vida; sin embargo, para que esta estrategia tenga el éxito esperado, es necesario evaluar su desarrollo y medir su aceptación en los usuarios finales. El presente trabajo muestra los resultados de una investigación cuantitativa de alcance correlacional realizada en el Centro Universitario del Sur (CUSur de la Universidad de Guadalajara, la cual propone y prueba un modelo de evaluación de los cursos en línea desde la perspectiva del estudiante. La importancia de este estudio radica en que define e identifica de una forma sistemática las fortalezas y debilidades de los cursos en línea desde la perspectiva de los estudiantes, lo que permite enfocarse en las áreas que muestran mayor debilidad para fortalecerlas y, de esta manera, lograr una mayor aceptación de los usuarios de esta modalidad. Los resultados muestran que las dimensiones de Gestión y Apoyos fueron las mejor evaluadas y que, si bien todas las dimensiones influyen en su conjunto significativamente en el modelo, las dimensiones Pedagógica y de Evaluación son las de mayor influencia.

    2006-01-01

    The Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning (CPD) is a joint undertaking according to Article 5 of the Statute of the NEA. Concluded in 1985, the Agreement of the 23 participating organisations constituting the CPD has been continuously extended with the current programme period lasting until 2009. This report provides information about the participants, structure and achievements of the Co-operative Programme. The objective of the CPD is to acquire information and share operational experience from the conduct of 42 current decommissioning projects, such as project description and design, data resulting from the execution of decommissioning projects, and associated research and development results. The information generated in the project is protected by confidentiality provisions, which allow for a frank and open exchange of experiences, on a 'give and take' basis. The information exchange also ensures that the best internationally available experience is available and that safe, environmentally friendly and cost effective methods are employed in all decommissioning projects. The Co-operative Programme is implemented by a Management Board (MB) representing the participating organisations and a Technical Advisory Group (TAG) for the information exchange between the individual decommissioning projects. The latter benefits from the support of a Programme Co-ordinator financed by the Programme. The projects in the Programme have a broad range of characteristics and cover various types of reactors and fuel facilities. The Programme now covers 26 reactors, 8 reprocessing plants and 8 fuel facility projects, representing a wide selection of facility types in each category. Also, all three stages of decommissioning - from active dismantling to safe-store and to completed decommissioning back to 'green field conditions' - are represented. Over the 20 years of experience of the Co

En la actualidad, las neoplasias inducidas por virus pueden agruparse en tumores sólidos y procesos linfoproliferativos. Destacan entre los primeros el VPH, del cual ahora conocemos numerosos serotipos, cada uno vinculado a una neoplasia específica, el herpesvirus humano tipo 8 que produce el sarcoma de Kaposi y el poliomavirus vinculado al carcinoma de Merkel. Entre los procesos linfoproliferativos debemos mencionar al virus linfotrópico de células T humanas tipo 1 (HTLV-1 responsable de los linfomas de células T, en los cuales el compromiso cutáneo es inespecífico, con un amplio espectro de presentaciones clínicas y, que por consiguiente, plantean un reto para el diagnóstico diferencial. En este grupo también se encuentra el virus Epstein Barr vinculado a los linfomas nasales de Células NK/T y a los linfomas tipo Hidroa, de reciente descripción.

Four sedimentological profiles have been described and analyzed. Morphological and analytical results show that the pedon was homogeneous before being modified by several periglacial episodes. It Is also possible to observe that the deformation was heterogeneous and it did not imply overlapping between the horizons. These data allow us to conclude that soil deformation and polygonal shaping were the result of both processes: a thermal convection of water; b upward thrust from the permafrost top layer.

    This report is in response to an action placed on SEGFSM members to compile ongoing and planned fuel safety research in NEA member states with the aim of providing CSNI an overview on related R and D international programmes and projects, along with the identification of current and future needs and priorities. A questionnaire was distributed to SEGFSM members on 18 October 2000, requesting them to identify fuel safety research programmes and to provide information on achievements and future plans. The questionnaire required respondents to provide information on the ongoing R and D programmes under the following headings: Title; Research Laboratory/Sponsor(s); Objectives/Goals; Status of Work; Brief description/presentation of the main results achieved; Future plans; References. Replies were received from organizations in the following countries: Belgium, Canada, Czech Republic, France, Germany, Hungary, Japan, Korea, Norway (Halden Reactor Project), Sweden, Switzerland, United Kingdom, USA. The report is based on the information provided in the replies received, as a consequence it cannot be viewed as comprehensive; programmes may well be in progress in addition to those detailed here. It is also possible that the detailed results of some programmes may remain proprietary and therefore not available in the short term. The report is organized in topic sections relating to: fuel and clad studies, integral fuel rod tests and PIE, LOCA and RIA studies including whole rods and bundles as well as single effects studies of fuel and cladding, code development for both steady state and transient fuel behaviour, thermal hydraulics, reactor physics codes and finally severe accident studies. The main issues for the current generation of reactors are those of high burn-up performance in normal operations, LOCA and RIA conditions and the main goal for the industry is to consolidate the safety issues to bring all countries up to a licensed discharge burn-up of ∼60 MWd/kg in

    Due to the drawbacks of conventional negative electron affinity (NEA) GaN photocathodes activated by Cs or Cs/O, a new-type NEA GaN photocathodes with heterojunction surface dispense with Cs activation are proposed. This structure can be obtained through the coverage of an ultrathin n-type Si-doped GaN cap layer on the p-type Mg-doped GaN emission layer. The influences of the cap layer on the photocathode are calculated using DFT. This study indicates that the n-type cap layer can promote the photoemission characteristics of GaN photocathode and demonstrates the probability of the preparation of a NEA GaN photocathode with an n-type cap layer.

O crescimento e o acúmulo de nutrientes pela parte aérea de espontâneas e de leguminosas utilizadas como adubos verdes foram medidos em um experimento de campo em Sete Lagoas (MG, na Embrapa Milho e Sorgo. O experimento consistiu de cinco espécies de leguminosas (feijão-de-porco, feijão-bravo do Ceará, mucuna-preta, lab-lab e guandu, submetidas a duas condições de manejo (com e sem capina, e uma testemunha (somente espontâneas. No florescimento das leguminosas, foram obtidos a massa da matéria seca e o teor de nutrientes da parte aérea de cada espécie de leguminosa e das espontâneas presentes nas parcelas. O sistema com apenas as espontâneas produziu menos biomassa e acumulou menos nutrientes que os sistemas com leguminosas. Foram poucas as espontâneas que apresentaram teores de carbono, cálcio e nitrogênio próximos ou superiores aos das leguminosas. No entanto, para potássio, magnésio e fósforo, ocorreu o inverso. A maioria das espontâneas apresentou teores de potássio, magnésio e de fósforo superiores aos das leguminosas, destacando-se: Portulaca oleracea, Euphorbia heterophylla, Bidens pilosa, Commelina benghalensis e Melanpodium perfoliatum.

    1992-07-01

    OECD member countries have adopted various accident management measures and procedures. To initiate these measures and control their effectiveness, information on the status of the plant and on accident symptoms is necessary. This information includes physical data (pressure, temperatures, hydrogen concentrations, etc.) but also data on the condition of components such as pumps, valves, power supplies, etc. In response to proposals made by the CSNI - PWG 4 Task Group on Containment Aspects of Severe Accident Management (CAM) and endorsed by PWG 4, CSNI has decided to sponsor a Specialist Meeting on Instrumentation to Manage Severe Accidents. The knowledge-basis for the Specialist Meeting was the paper on 'Instrumentation for Accident Management in Containment'. This technical document (NEA/CSNI/R(92)4) was prepared by the CSNI - Principle Working Group Number 4 of experts on January 1992. The Specialist Meeting was structured in the following sessions: I. Information Needs for Managing Severe Accidents, II. Capabilities and Limitations of Existing Instrumentation, III. Unconventional Use and Further Development of Instrumentation, IV. Operational Aids and Artificial Intelligence. The Specialist Meeting concentrated on existing instrumentation and its possible use under severe accident conditions; it also examined developments underway and planed. Desirable new instrumentation was discussed briefly. The interactions and discussions during the sessions were helpful to bring different perspectives to bear, thus sharpening the thinking of all. Questions were raised concerning the long-term viability of current (or added) instrumentation. It must be realized that the subject of instrumentation to manage severe accidents is very new, and that no international meeting on this topic was held previously. One of the objectives was to bring this important issue to the attention of both safety authorities and experts. It could be seen from several of the presentations and from

    The NEA Stripa project has devoted considerable effort to the measurement and assessment of the hydrogeology, hydrogeochemistry and migration phenomena of the stripa granite and to the simulation of conditions likely to be found within an engineered repository in granitic rock. These include refining existing, and developing new, geophysical and hydraulic techniques for the mapping and characterization of fractures in crystalline rocks; conducting field experiments to assess the migration of tracers in single-and multiple-fracture systems; and studying the behaviour of bentonite clay as the back-filling and sealing material in a granitic environment. This paper summarizes the most important findings and outlines the main aims of possible future research under any phase 3 of the project. The latter may include making mathematical predictions of the hydrogeological behavior of the Stripa granite and their subsequent validation by field measurements

    2001-01-01

    One of the options envisaged for disposing of weapons grade plutonium, declared surplus for national defence in the Russian Federation and Usa, is to burn it in nuclear power reactors. The scientific/technical know-how accumulated in the use of MOX as a fuel for electricity generation is of great relevance for the plutonium disposition programmes. An Expert Group of the OECD/Nea is carrying out a series of benchmarks with the aim of facilitating the use of this know-how for meeting this objective. This paper describes the background that led to establishing the Expert Group, and the present status of results from these benchmarks. The benchmark studies cover a theoretical reactor physics benchmark on a VVER-1000 core loaded with MOX, two experimental benchmarks on MOX lattices and a benchmark concerned with MOX fuel behaviour for both solid and hollow pellets. First conclusions are outlined as well as future work. (author)

    2000-01-01

    Although the safety level of nuclear power plants in OECD countries is very satisfactory and the technologies basic to the resolution of safety issues have advanced considerably, continued nuclear safety research work is necessary to address many of the residual concerns, and it remains an important element in ensuring the safe operation of nuclear power plants. However, the funding levels of national Government safety research programmes have been reduced over recent years. There is concern about the ability of OECD Member countries to sustain an adequate level of nuclear safety research capability. The OECD/NEA has a key role to play in organizing reflection and exchange of information on the most efficient use of available technical resources, and in the international management of nuclear safety research facilities and capabilities in a changing nuclear industry. Possible initiatives are mentioned in the paper. (author)

  4. The regulator's evolving role and image in radioactive waste management. Lessons learnt within the Nea forum on stake holder confidence

    International Nuclear Information System (INIS)

    2003-01-01

    Of all the institutional actors in the field of long-term radioactive waste management (RWM), it is perhaps the regulatory authorities that have restyled their roles most significantly. Modern societal demands on risk governance and the widespread adoption of stepwise decision-making processes have influenced the image and role of regulators. Legal instruments both reflect and encourage a new set of behaviours and a new understanding of how regulators may best serve the public interest. This report, based on the work of the NEA Forum on Stakeholder Confidence, presents findings of relevance to regulators and examines their role within a robust and transparent RWM decision-making process. Detailed international observations are provided on the role of regulatory authorities; characteristics of the regulatory process; attributes that help achieve public confidence; and regulatory communication approaches.

    The Pebble Bed Modular Reactor (PBMR) is a High-Temperature Gas-cooled Reactor (HTGR) concept to be built in South Africa. As part of the verification and validation program the definition and execution of code-to-code benchmark exercises are important. The Nuclear Energy Agency (NEA) of the Organisation for Economic Cooperation and Development (OECD) has accepted, through the Nuclear Science Committee (NSC), the inclusion of the Pebble-Bed Modular Reactor (PBMR) coupled neutronics/thermal hydraulics transient benchmark problem in its program. The OECD benchmark defines steady-state and transients cases, including reactivity insertion transients. It makes use of a common set of cross sections (to eliminate uncertainties between different codes) and includes specific simplifications to the design to limit the need for participants to introduce approximations in their models. In this paper the detailed specification is explained, including the test cases to be calculated and the results required from participants. (authors)

    Full Text Available Este artículo intenta presentar un análisis de los personajes homosexuales femeninos en las obras Duas iguais, de Cíntia Moscovich, y Todos nós adorávamos caubóis, de Carol Bensimon. Para ésto presenta una breve investigación de los enfoques presentes en la literatura brasileña, desde el Barroco hasta el Modernismo, a partir del carácter del amor entre mujeres. Al hacer la comparación entre las dos obras contemporáneas y las obras antiguas, se pretende comprender cómo se da la representación del personaje homosexual femenino y la manera en que esa representación fue modificándose a lo largo de los años en Brasil.

    The sensitivities of the k{sub eff} eigenvalue to neutron cross sections have become commonly used in similarity studies and as part of the validation algorithm for criticality safety assessments. To test calculations of the sensitivity coefficients, a benchmark study (Phase III) has been established by the OECD-NEA/WPNCS/EG UACSA (Expert Group on Uncertainty Analysis for Criticality Safety Assessment). This paper presents some sensitivity results generated by the benchmark participants using various computational tools based upon different computational methods: SCALE/TSUNAMI-3D and -1D, MONK, APOLLO2-MORET 5, DRAGON-SUSD3D and MMKKENO. The study demonstrates the performance of the tools. It also illustrates how model simplifications impact the sensitivity results and demonstrates the importance of 'implicit' (self-shielding) sensitivities. This work has been a useful step towards verification of the existing and developed sensitivity analysis methods. (authors)

    Full Text Available O artigo tem como objetivo analisar a recíproca dependência dos direitos fundamentais, democracia e da paz, como três momentos integrantes do mesmo movimento histórico. Sem a devida proteção das liberdades fundamentais não se perfaz um governo democrático, pois, aludido regime sustenta-se na soberania popular, na separação de poderes e respeito pleno aos direitos humanos. Por outro lado, nota-se a paz como elemento intrínseco da ordem republicana, posto que fundada segundo os princípios cardeais da liberdade, igualdade e solidariedade. Destarte, necessária se faz uma interpretação contemporânea buscando, sobretudo, o fortalecimento gradual e simultâneo desses três valores essenciais.

    Full Text Available La lipotransferencia en muslos y piernas es un procedimiento muy poco empleado como complemento a la lipoescultura, siendo ésta una zona muy importante para dar más armonía y belleza al contorno corporal. Analizamos 139 procedimientos de lipotrasnferencia en muslos y piernas, ésta última complementada con o sin fasciotomía subcutánea de la aponeurosis tibial posterior o fascia profunda de la pierna. Describimos la técnica y las cantidades de grasa empleadas según zonas disminuyendo al mínimo las complicaciones y reacciones secundarias, que cuando se producen en las piernas, y si no se ha realizado la fasciotomía, puede confundir con otras patologías tales como es el síndrome compartimental y/o la trombosis venosa profunda.

    Neste caso clínico descrevemos a migração tardia da ponta de um CVC. Este fenómeno não é incomum e foram já descritos vários destinos anatómicos para estas migrações como a veia braquiocefálica oposta ou a veia jugular [1]. A incidência destas migrações espontâneas foi estimada em 0.9-1.8%, sendo que o mecanismo exato permanece obscuro. Algumas hipótese incluem variações extremas da pressão intratorácica por tosse, espilros ou levantamento de pesos por exemplo [2].

    Full Text Available RESUMEN: El interés que ha despertado el estudio de la sociabilidad desde hace algunos años, nos ha llevado a preocuparnos por una sistematización sobre los componentes políticos en algunos modelos de asociaciones. Nuestro trabajo delimita las tipologías que configuran unas prácticas políticas innovadoras que derivan de la aparición de nuevos comportamientos sociales y del establecimiento de relaciones inter-personales más ágiles. Estos nuevos códigos son, en suma, la manifestación de un profundo cambio cultural de los universos políticos en la España contemporánea. Partiendo de estas nuevas bases, nos acercaremos a la formación de los partidos políticos modernos en tanto que elementos receptores de esta nueva cultura política. Palabras Clave. Sociabilidad, cultura política, redes y partidos, España contemporánea. ABSTRACT: Our study of sociability for several years, has led us to adopt a systématisation approach to the political aspects of certain forms of association. This work focuses on the typologies of new social behaviours and changing interpersonal relations. All in all, these new codes express the deep cultural change in the political spheres in present-day Spain. In light of these facts, we investigate the formation of sociability networks as well as the origins of modern political parties, viewed as receptive elements of n ew political culture. Key Words: Sociability^ political cultures, networks and political parties, Contemporary Spain.

    Full Text Available Con el objetivo de evaluar la respuesta de 18 líneas experimentales y dos genotipos comerciales de tomate ( Solanum lycopersicum L. ante la infección natural de patógenos ( Alternaria solani, Phytophthora infestans, Fusarium oxysporum, Nacobbus spp . y Meloidogyne spp . de importancia económica, se realizó un ensayo en el campo agrícola experimental de la Universidad Autónoma Chapingo con el diseño experimental bloques completos al azar con cuatro repeticiones. Se evaluó el grado de severidad de cinco patógenos sobre las plantas de los genotipos considerados. Previo a la evaluación se identificó a cada patógeno en laboratorio por medio de la morfología de sus estructuras reproductivas. Se aplicó la prueba no paramétrica de Friedman a los datos obtenidos y posteriormente se realizó la comparación múltiple de rangos. Se detectaron fuentes de resistencia para Alternaria solani con severidad final del 35 %, en comparación con los genotipos susceptibles que fue del 80 %. En el caso de Phytopthora infestans la severidad final alcanzó 60 %, mientras que la susceptibilidad correspondió a 100 %. En el caso de Fusarium oxysporum se obtuvo un valor de 10 % de daño contra los susceptibles con 40 % . Con respecto a nematodos ( Nacobbus spp. y Meloidogyne spp., se determinó tolerancia con registros de 30 % de agallamiento y 76 % en líneas susceptibles.
