  2. Activities developed by the biological dosimetry laboratory of the Autoridad Regulatoria Nuclear - ARN of Argentina

    International Nuclear Information System (INIS)

    Biological dosimetry (DB) allows to estimate doses absorbed in individuals exposed to ionizing radiation through the quantification of stable and unstable chromosome aberrations (SCA and UCA). The frequency of these aberrations is referred to a calibration dose response curve (in vitro) to determine the doses of the individual to the whole body. The DB is a necessary support for programs of national radiation protection and response systems in nuclear or radiological emergencies in the event of accidental or incidental, single overexposure or large scale. In this context the Laboratory of Dosimetry Biological (LDB) of the Authority Regulatory Nuclear (ARN) Argentina develops and applies different dosimeters cytogenetic from four decades ago. These dosimeters provide a fact more within the whole of the information necessary for an accidental, complementing the physical and clinical dosimetry exposure assessment. The most widely used in the DB biodosimetric method is the quantification of SCA (dicentrics and rings Central) from a sample of venous blood. The LDB is accredited for the trial, under rules IRAM 301: 2005 (ISO / IEC 17025: 2005) and ISO 19238:2004. Test applies to the immediate dosimetry evaluation of acute exposures, all or a large part of the body in the range 0,1-5 Gy. In this context the LDB is part of the Latin American network of DB (LBDNet), BioDoseNet-who and response system in radiological emergencies and nuclear IAEA-RANET, being enabled to summon the LBDNet if necessary

    Full text: A radiochemical laboratory must count with optimized analytical techniques and calibrated measurement systems in order to get reliable results. In addition to the internal controls that each laboratory must carry out, it is indispensable to include in the quality assurance programs, intercomparisons with qualified laboratories. The Nuclear Regulatory Authority (ARN) of the Republica Argentina participates since 1995, in the Quality Assessment Program organized by the Environmental Measurements Laboratory - EML, of the United States. The participation in this program consist in: 1) Measurement of different gamma emitters in 4 environmental matrixes: water, filter, soil and vegetation; 2) Determination of actinides in the named matrixes; 3) Determination of tritium and iron-55 in water; 4) Determination of strontium-90 in water, filter, soil and vegetation; 5) Gross alpha and gross beta measurement in water and filter. In this paper, the results of the ARN in the six previous intercomparisons are exposed. An analysis of the deviations of the informed dates related to the EML values are made, and they are compared with the results of the rest of the participating laboratories. The determination methods and the measurement systems utilized in each matrix and for each radionuclide, are mentioned. (author)

    The Argentine Nuclear Regulatory Authority (ARN) like essential part of their strategic institutional plan and in the mark of the modernization of the National Public Administration (NPA), identify the necessity to modify their functional organization, introducing the administration for processes and defining more flexible and better guided structures to the work in team. Starting from the definition of a new institutional flowchart it decided to proceed to a general reorganization of the human resources and on January, 2005 it was prepared the creation of a process whose serious objective to sit down the bases for the development of the professional career of the ARN. To such an end, it was thought about a work outline by stages, the first one of which had as final objective the elaboration of the Labor Profiles of the Institution. The work group for this first stage was integrated by a group of professionals of long trajectory in the institution and not belonging to the sector of Human Resources (RRHH). By this way it was organized as an independent group that it worked in narrow collaboration with the specific sector and informed directly to the maximum institutional direction. For the construction of the profiles a 'mixed' model was chosen that included the requirements of each position (that to make) and the competitions to complete them (how to make it), since a focus purely of competitions has not been seen as the more appropriate for the public administration and in particular for the ARN. In this work it is given to know a part of the results obtained during six months of effective work of the PerLa Group (denominated as well as an acronym of the expression Labor Profiles) putting emphasis in the defined profiles for the inspectors of those different regulatory branches that constitute the environment of competition of the RNA, this is Radiological Protection, Nuclear Safety, Safeguards and Physical Protection.

    The electrical power generation using nuclear power plants requires this installation being safety, reliable and available for the working periods. For this purpose, an adequate, effective and well conducted maintenance program makes an essential and useful tool to the owner of the plant. However, it is necessary to follow the regulatory requirements for this program implementation which monitories this maintenance effectiveness. There are Brazilian norms requirements which must be followed. The international regulatory guides establish these requirements in good details but it is necessary to verify if this methodology for implementing can be totally applied here in Brazil. Then, the american guide NUMARC 93-01 which details how can be implemented a program for this monitoring, shows some methods for using. In this thesis, the Delphi and Probabilistic Safety Analysis were briefly included because they were preferred for implementing this monitoring.in a Brazilian plant. The results which are being obtained show that, looking the regulatory aspects, the NUMARC 93-01 follows our regulations and gives good results for the plant management. (author)

    The Autoridad Regulatoria Nuclear of Argentina (ARN), the International Atomic Energy Agency (IAEA), ABACC, the US Department of Energy, and the US Support Program POTAS, cooperated in the development of a Remote Monitoring System for nuclear nonproliferation efforts. This system was installed at the Embalse Nuclear Power Station last year to evaluate the feasibility of using radiation sensors in monitoring the transfer of spent fuel from the spent fuel pond to dry storage. The key element in this process is to maintain continuity of knowledge throughout the entire transfer process. This project evaluated the fundamental design and implementation of the Remote Monitoring System in its application to regional and international safeguard efficiency. New technology has been developed to enhance the design of the system to include storage capability on board sensor platforms. This evaluation has led to design enhancements that will assure that no data loss will occur during loss of RF transmission of the sensors.

    The mandatory character documentation of the Argentinean nuclear power stations in Embalse and Atucha I, required the realization of a programmed stoppings every twelve months to execute that settled down in the maintenance and surveillance programs for each installation. Nucleoelectrica Argentina S.A., in it character of Responsible Entity of the operation of these power stations, requested to the Argentinean Nuclear Regulatory Authority, in 2003 and 2005 respectively, the authorization to change the period of the repetitive tests and of the preventive maintenance of the systems related with the safety, to extend them from twelve to eighteen months. The mentioned applications were founded in economic aspects and in inclining to a decrease in the doses of the workers that perform in the activities that are carried out in the programmed stops. The adopted position by the Nuclear Regulatory Authority to decide on these applications was based on the result of diverse evaluations that included the use of the Probabilistic Analysis of Safety specific of each power station, the operative experience resultant of the execution of the preventive maintenance program, and of the results of the repetitive tests and of the inspections in service. The regulatory decisions were different in each case. Indeed, the Embalse nuclear power station was authorized by the Regulatory Authority to modify from twelve to eighteen months the period among the realization of the repetitive tests and of the preventive maintenance, conditioned to the execution of some specific regulatory requirements. On the other hand, the Atucha I nuclear power station was not authorized to modify this period.

    A new integrated regulatory structure based on quality and integrated issues has been proposed to be implemented on the licensing process of nuclear research reactors in Brazil. The study starts with a literature review about the licensing process in several countries, all of them members of the International Atomic Energy Agency. After this phase it is performed a comparative study with the Brazilian licensing process to identify good practices (positive aspects), the gaps on it and to propose an approach of an integrated quality and environmental management system, in order to contribute with a new licensing process scheme in Brazil. The literature review considered the following research nuclear reactors: Jules-Horowitz and OSIRIS (France), Hanaro (Korea), Maples 1 and 2 (Canada), OPAL (Australia), Pallas (Holand), ETRR-2 (Egypt) and IEA-R1 (Brazil). The current nuclear research reactors licensing process in Brazil is conducted by two regulatory bodies: the Brazilian National Nuclear Energy Commission (CNEN) and the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). CNEN is responsible by nuclear issues, while IBAMA by environmental one. To support the study it was applied a questionnaire and interviews based on the current regulatory structure to four nuclear research reactors in Brazil. Nowadays, the nuclear research reactor’s licensing process, in Brazil, has six phases and the environmental licensing process has three phases. A correlation study among these phases leads to a proposal of a new quality and environmental integrated licensing structure with four harmonized phases, hence reducing potential delays in this process.

  1. Current situation of the facilities, equipments and human resources in nuclear medicine in Argentina

    International Nuclear Information System (INIS)

    The current situation of nuclear medicine in Argentina, taking into account the facilities, their equipment and human resources available is presented in this paper. A review and analysis of the equipment, including technical characteristics and a survey of the professionals and technicians of the area, was carried out. In Argentina, there are 266 centers of nuclear medicine distributed all over the country. The operating licenses are granted by the Nuclear Regulatory Authority (Autoridad Regulatoria Nuclear - ARN). Forty four percent of the installed equipment are SPECT of 1 or 2 heads and 39,4 % are gamma camera. Besides, there are eleven PET operating in Argentina. There are 416 nuclear medicine physicians with individual permit for diagnostic purposes and 50% of them has also individual permit for treatment purposes. With the purpose of analyzing the regional distribution of the available resources in nuclear medicine, the country was divided into 7 geographical regions: City of Buenos Aires, Province of Buenos Aires, Pampa, Cuyo, Northeast, Northwest and Patagonia. From the analysis of the gathered information it is possible to conclude that the nuclear medicine equipment as well as the personnel present an irregular distribution, with a major concentration in the City of Buenos Aires and Province of Buenos Aires. The Northeast region presents the lowest number of Nuclear Medicine centers and the Patagonia region has the lowest number of medicine nuclear physicians with individual permits. The number of SPECT and gamma cameras is 7,3 per million of inhabitants. The information about the available resources in nuclear medicine presented in this paper and its comparison with the international information available provide elements for a better planning of the future activities in the area not only for the operators but also from the regulatory point of view.

  4. Workshop on internal dosimetry in the nuclear fuel cycle

    International Nuclear Information System (INIS)

    Dose assessment in case of internal exposure involves the estimation of committed effective dose based on the interpretation of bioassay measurement, and the assumptions of hypotheses on the characteristics of the radioactive material and the time pattern and the pathway of intake. In the case of workers exposed in nuclear fuel facilities, the normal uranium excretion from the diet is an additional difficulty in the process of assessing internal exposure. The aim of this paper is to present the main topics discussion and the conclusions of the workshop, held in the frame of the missions of the Autoridad Regulatoria Nuclear. All the personnel involved in the control of internal exposure in nuclear fuel cycle was invited to participate in the workshop to discuss about individual monitoring criteria and the available tools for assessing committed effective dose in the workers of their facilities. The lectures were presented jointly by the Nuclear Fuel Cycle Facilities Control and the Dosimetric and Radiobiological Assessment departments. It was hold at the Ezeiza Atomic Center from 23th to 24th November 2010 based on the Advanced Course on Internal Dosimetry organized on 2009 and focusing specific uranium compound internal dosimetry. A representative of each facility was invited to present the monitoring program implemented for controlling the internal exposure. It was an opportunity to discuss criteria and to share experiences on this field in the frame of the ICRP, HPA and ISO publications. The different monitoring program criteria could be analyzed and so contributing to the improvement of radiological protection. Finally, it was agreed to hold periodical meetings to assure the update on uranium measurement techniques and the handling of monitoring data for committed effective dose assessment. (authors)

    Full Text Available El manejo de agua en Aguascalientes se ha estudiado desde la perspectiva del suministro, pero no se ha analizado la gobernanza del agua residual. En este artículo se examina el manejo de efluentes del municipio de Aguascalientes utilizando las teorías del neoinstitucionalismo histórico, de la gobernanza y de la captura regulatoria. Se explica los factores que han influido en la operación reciente (2010-2013 del tratamiento y reuso de agua municipal. El análisis está fundamentado en los debates contemporáneos sobre priva - tización del recurso hídrico, y enfocado en el periodo de la administración priista de Lorena Martínez, y sus proyectos emblemáticos: Línea Verde y Líneas Moradas.

    Full Text Available Parte-se da constatação de que crianças e adultos carecem de referências nas formas de lidarem uns com os outros, crise que vem sendo justamente denunciada pela juventude por meio de atitudes de enfrentamento aos adultos. Ao retomar-se o percurso histórico da autoridade, percebe-se que ela não se liga a apenas um significado, mas toma contornos diferenciados. Este artigo objetiva discutir relações entre autoridade e hierarquia, autoridade e poder, autoridade e fundação, que ajudam a compreender que aquilo que se mostrava como "verdade" não dá conta das vicissitudes das relações humanas atuais, apontando para outras construções possíveis do sentido da autoridade.

    Full Text Available Resumen: El descubrimiento de nuevos yacimientos petrolíferos y la apuesta por combustibles ecológicos perfilan a Brasil como un líder energético mundial. Sin embargo, este logro no sólo puede sostenerse en la riqueza natural del país, sino que requiere de un modelo basado en políticas energéticas eficientes y sostenibles. El modelo energético brasileño parece mantener tales principios, de un lado con la nueva Ley de Hidrocarburos que garantiza al gobierno el control de estos recursos y de otro con la producción de biocombustibles y etanol. Si bien podemos considerar que la explicación al éxito energético brasileño se centra en gran medida en la disposición de recursos naturales, en este trabajo se argumenta que la gobernanza regulatoria del sector energético desarrollada desde los noventa en Brasil es un factor explicativo directo del mismo, que ha dotado al país de una posición estratégica en América Latina. Finalmente, se tratará de ver cómo el desarrollo energético puede influir en el desarrollo social a través de uno de los países más desiguales de América Latina.

  11. Criticality and shielding calculations of an interim dry storage system for the spent fuel from Atucha I Nuclear Power Plant

    International Nuclear Information System (INIS)

    The Atucha I Nuclear Power Plant (CNA-I) has enough room to store its spent fuel (SF) in damp in its two pool houses until the middle of 2015.Before that date there is the need to have an interim dry storage system for spent fuel that would make possible to empty at least one of the pools, whether to keep the plant operating if its useful life is extended, or to be able to empty the reactor core in case of decommissioning.Nucleolectrica Argentina S.A. (NA-SA) and the Comision Nacional de Energia Atomica (CNEA), due to their joint responsibility in the management of the SF, have proposed interim dry storage systems.These systems have to be evaluated in order to choose one of them by the end of 2006.In this work the Monte Carlo code MCNP was used to make the criticality and shielding calculations corresponding to the model proposed by CNEA.This model suggests the store of sealed containers with 36 or 37 SF in concrete modules.Each one of the containers is filled in the pool houses and transported to the module in a transference cask with lead walls.The results of the criticality calculations indicates that the solutions of SF proposed have widely fulfilled the requirements of subcriticality, even in supposed extreme accidental situations.Regarding the transference cask, the SF dose rate estimations allow us to make a feedback for the design aiming to the geometry and shielding improvements.Regarding the store modules, thicknesses ranges of concrete walls are suggested in order to fulfill the dose requirements stated by the Autoridad Regulatoria Nuclear Argentina

    Full Text Available La esclerosis múltiple (EM es una enfermedad inflamatoria autoinmune desmielinizante del sistema nervioso central (SNC. La mayoría de las enfermedades autoinmunes se originan por la activación anormal de la respuesta inflamatoria contra auto-antígenos (la mayoría de ellos desconocidos a la fecha como consecuencia de la pérdida de la tolerancia periférica. Las células T-regulatorias constituyen un grupo esencial de linfocitos T encargados del mantenimiento de la tolerancia periférica, la prevención de enfermedades autoinmunes y la limitación de enfermedades inflamatorias crónicas. Teniendo en cuenta la importancia de la tolerancia periférica, las células T-regulatorias serían componentes cruciales en el escenario fisiopatológico de los procesos autoinmunes, incluyendo la EM. El presente trabajo recopila los conocimientos actuales sobre la función de las células T-regulatorias en la EM, la enfermedad autoinmune desmielinizante del SNC más prevalente en los seres humanos.Multiple sclerosis (MS is an autoimmune inflammatory demyelinating disease of the central nervous system (CNS. Most of autoimmune diseases arise by an abnormal activation of the inflammatory response against self-antigens (most of them unknown up to date as a consequence of dysfunction in peripheral tolerance. Regulatory T-cells are essential for maintaining peripheral tolerance, preventing autoimmune diseases and limiting chronic inflammatory conditions. Based on that knowledge, T-regulatory cells have emerged as a key component of the physiopathology of autoimmune diseases including MS. This review compiles the current knowledge on the role and function of T-regulatory cells in MS, the most prevalent CNS autoimmune disease in humans.

    2015-01-01

    Full Text Available La discusión sobre el lugar de la autoridad en el proceso educativo escolar ha movilizado intelectuales, profesores y responsables políticos. Los dis - cursos se alternan entre la queja y el lamento, entre el rechazo de las rela - ciones fundadas en la autoridad y la búsqueda de la restauración de una supuesta autoridad perdida. Este artículo pretende aclarar que, a pesar de las diferencias teóricas y programáticas entre estas dos tendencias de los discursos, ambas tienen un aspecto común: no distinguen la obediencia producida por una relación de autoridad –siempre fundada en la confianza– de otras forma de obediencia, como las que son producidas por la violen - cia, la coacción o la adhesión a normas legales. Por lo tanto, el debate sobre los dilemas y dificultades relacionadas con la disminución de la autoridad en las relaciones educativas del mundo moderno requiere la comprensión de la especificidad de este tipo de relación y de los regímenes temporales que rigen los nexos que las sociedades establecen entre presente, pasado y futuro.

    Se plantean aspectos varios –ámbito jurídicopenal, político, social, doctrinal- , recogidos de fuentes diversas y con reflexiones propias, sobre las consecuencias de poner en vigencia una Ley de Autoridad del Profesorado, así como una revisión del estado legal de la situación  a nivel de las Comunidades Autónomas -y una mínima referencia a la situación en Europa-, dado que desde el Gobierno central no se ha propuesto hasta la fecha establecer las bases comunes de una normativa que aparece dispersa y que está creando distorsiones en la condición jurídica del profesorado según el lugar de España donde se ejerza. Tras el análisis de la cuestión, se pone en evidencia que el sentido de la promulgación de una ley de autoridad del profesorado es claramente controvertido y por ello criticable, expuesto a razones ideológicas y de efectos prácticos.

  1. Lepra, exageración y autoridad médica

    Full Text Available In this article I analyze the reaction of Colombian physicians in the late nineteenth century towards what they saw as the growing number of people infected with leprosy in Colombia. Based on an incomplete census, doctors exaggerated the number of infected people to medicalize the disease because the care of patients was in the hands of philanthropic institutions. I examine the attitude of doctors as related to their perceived need of reinforcing their cultural authority, displaying their scientific competence in front of other social groups, and building a national medicine that would give them visibility in the international arena. Physicians found further justification in new bacteriological theories which conceptualized leprosy as a highly contagious and dangerous disease. In this period, medicine became a profession in Colombia: its teaching became stabilized in the National University and the doctors created societies and academies which contributed to their professionalizacion. Therefore, leprosy was used by the Colombian medical community in its process of building their scientific authority and enlarging their professional power.

    En este artículo se analiza la reacción de los médicos colombianos de finales del siglo XIX frente a lo que ellos consideraron el aumento del número de enfermos de lepra en Colombia. Basándose en un censo defectuoso, los médicos exageraron los datos de contagiados con el fin de medicalizar la enfermedad, puesto que en esa época el cuidado de los enfermos estaba en manos de organizaciones filantrópicas. Se examina la actitud de los médicos frente a la lepra en relación con la necesidad de reforzar su autoridad cultural, desplegando su competencia científica frente a otros grupos sociales y de construir una medicina nacional que les diese visibilidad a nivel internacional. Los médicos encontraron justificación adicional para su actitud en las nuevas teorías bacteriológicas, que calificaban a

    Full Text Available This essay discusses the policies followed by the colonial church and state to Christianize the funerary rituals of ethnic authorities in the Peruvian Andes. From a comparative perspective, the essay studies this process in two cities of the Peruvian viceroyalty during the two first centuries of Spanish rule. The essay demonstrates that the changes operated were the result of ambivalent policies implemented by both church and state, and of distinct local power structures.

Se demuestra que las transformaciones operadas fueron producto de políticas de gobierno y evangelización ambivalentes y de estructuras locales de poder.

A través de los mismos los jefes étnicos legitiman su posición frente a la naciente sociedad colonial y ante sus propios ayllus. Se observan dos actitudes con respecto al uso de los mismos. Una es la adopción de formas pertenecientes a la cultura del colonizador ya que la integración de elementos foráneos es necesaria para la construcción y reconstrucción de la identidad y legitimidad cacicales. La otra es la utilización y alusión a símbolos de prestigio netamente andinos como vehículo de reafirmación de la identidad étnica local y como medio de lograr una jerarquización social frente al “otro” europeo en una sociedad en formación compuesta por españoles y andinos. Se examinan primero probanzas de mérito, reales cédulas y memoriales, cuyos protagonistas y/o autores son siempre señores étnicos que desean obtener algún beneficio material o de status social. Luego se analizan los cronistas andinos quienes mostraron en sus obras la naturaleza de la organización social de su pueblo, además de ser los primeros en expresar una crítica a la conquista. En ambos casos, sus autores hacen de la escritura un dispositivo decisivo para su reproducción e identidad como miembros de una elite

    Full Text Available El presente artículo analiza y valora la contribución de José Vasconcelos al desarrollo de la filosofía en México. Para ello opero una reconstrucción socioanalítica de la trayectoria social e intelectual de Vasconcelos y la comparo con otras trayectorias, con el fin de discriminar su forma de autoridad específica en el campo filosófico. Este trabajo comparativo pasa por dos niveles de análisis: las relaciones que estructuran el campo filosófico mexicano (P. Bourdieu y las interacciones entre agentes a nivel situacional (R. Collins. Finalmente, dicho análisis sociológico permite cuestionar determinados espacios comunes de la tradición filosófica, como por ejemplo: las formas de constitución del canon, los procesos de ruptura generacional o la creatividad como empresa individual del genio creador.Palabras claves: Sociología de la filosofía, campo filosófico, rituales de interacción, canon filosófico, filosofía mexicana.  ___________________________ABSTRACT:This paper analyzes and values the contribution of José Vasconcelos to the development of philosophy in Mexico. To get this aim, I make a socioanalytic reconstruction of Vascocenlos´s social and intelectual trajectory and I compare it with others trajectories, to distinguish his specific kind of authority in the philosophical field. This comparative work goes through two levels of analysis: the structure of the mexican philosophical field (P. Bourdieu and the interactions between agents in a situational level (R. Collins. Finally, this sociological analysis permits to critic some common areas of the philosophical tradition, for example: the manners in which the canon is made it up, the generational rupture processes, or creativity as an individual enterprise of the creator genius. Keywords: Sociology of philosophy, philosophical field, interaction rituals, philosophical canon, mexican philosophy.

    Full Text Available Mesmo com a grande relevância dos portos para o desenvolvimento econômico e social dos países, há uma questão que merece atenção dos gestores e da sociedade, é o fato que as atividades portuárias causam impactos ambientais, tais como assoreamento em meios aquáticos, alterações na fauna e flora, emissões atmosféricas, geração de resíduos sólidos, entre outros. Neste contexto, a gestão da informação ambiental é importante tanto para os gestores dos portos quanto para a sociedade, pois permite conhecer o nível de impacto gerado e o nível de sustentabilidade ao longo do tempo. Uma das formas de medir a informação é verificar o nível de comprometimento dos gestores com a gestão ambiental. Como conseqüência deste entendimento, a presente pesquisa visa identificar o nível de sustentabilidade ambiental na Autoridade Portuária de Valencia (APV. Como metodologia utilizou-se um questionário aplicado à alta direção da APV e realizou-se análise de conteúdo do Relatório de Sustentabilidade da APV para compreender o nível de sustentabilidade ambiental. Os resultados da aplicação do questionário demonstram um grande comprometimento da APV com aspectos ambientais (Materiais, Energia, Água, Biodiversidade, Emissões, Efluentes líquidos, Resíduos, Sanções administrativas e judiciais, Impactos dos produtos e serviços Impactos dos transportes, Multas, Sanções não-monetárias, Não-conformidades, contudo a análise do Relatório de Sustentabilidade demonstra que nem todos os itens são divulgados (80% divulgados. Verifica-se também que o comprometimento da APV não se limita ao discurso ou política ambiental do porto, mas também nos itens que demonstram e avaliam desempenho dos aspectos ambientais.

    Como resultados se destacan: sintetizar la caracterización teórica y práctica de la catalogación, enumerar sus puntos de tensión y señalar su proyección de futuro a partir de dotar de una estructura lógica los nuevos códigos catalográficos, que, necesariamente, deberán ser más concisos y pragmáticos; y sobre la base de los desarrollos que se operan en el control de autoridad bibliográfico.
    Las conclusiones de esta investigación serían: expertos de distintos países revisan los presupuestos teóricos y prácticos de la catalogación, ésta se renueva con los nuevos recursos y posibilidades tecnológicas y por efecto de los dos hechos anteriores, se revela como un medio de gestión y organización del conocimiento que hoy se presenta en Internet.

  18. La interpretación débil de la autoridad en la Teoría Pura del Derecho de Hans Kelsen

    2012-12-01

    Full Text Available Autoridad qua habilitación es la interpretación débil de la autoridad en los escritos de Hans Kelsen. Por un lado, esta interpretación parece no responder al problema de la autoridad como se conoce en la tradición. Por otro lado, ella se ajusta al positivismo jurídico. ¿Es Kelsen un positivista? No sin reservas. Él defiende la tesis de la normatividad junto con la tesis de la separación, pero es en todo caso discutible si la tesis de la normatividad obliga a una interpretación más fuerte de la autoridad que aquella modelada sobre la habilitación. En el ensayo, yo ofrezco un argumento prima facie en favor de una interpretación más fuerte de la autoridad en Kelsen. Argumento, sin embargo, que la evidencia textual tiene mucho peso en favor de la interpretación débil. Tanto la perspectiva estática como aquella dinámica de las normas son puntos de vista omnipresentes en la Teoría Pura del Derecho, y ambos reflejan diversas especies de habilitación como puntos conclusivos de las reconstrucciones de Kelsen.

    Full Text Available La autoridad pedagógica del profesor en el aula tal como se ha entendido de manera tradicional en las escuelas ha llegado a su fin. Parece necesario entonces comprender la autoridad que hoy se da en las aulas desde nuevos referentes teóricos y prácticos para formar a los futuros profesores. Una tarea para ello consiste en identificar las formas desde dónde se construye actualmente la autoridad pedagógica del profesor. Este trabajo contribuye a tal tarea presentando los desafíos teórico-prácticos que plantea el proceso de construcción de una propuesta de protocolo de observación de la autoridad pedagógica. Se utiliza una metodología cualitativa que considera tanto el juicio de expertos como una prueba piloto y se asume un modelo de toma de decisiones deliberativo. En relación al qué y cómo observar, la principal conclusión consiste en afirmar que un protocolo de observación sobre autoridad pedagógica que tiene como propósito abrirse a su actual ejercicio debe desplazar la atención desde la figura del profesor a las interacciones. El foco en la interacción permitiría la observación de nuevas formas de legitimación de la autoridad que los jóvenes hoy realizan, permitiendo la superación del sesgo que puedan traer los observadores quienes pertenecen a otra generación.

    Full Text Available This paper examines the scope and characteristics of anticlerical violence between February and June 1936. Different primary sources have been used to reach an accurate and complete data as possible of such violence. First, we analyze the context in which this took place. Second, we present the data resulting from quantitative and qualitative research of anticlerical violence. And third, we discuss about the response to this phenomenon of various authorities. The article provides evidence that the anticlerical violence data that have been handled so far were fragmentary and did not provide the magnitude and general character which reached in the months immediately preceding the Civil War. It also shows that the government’s reaction was ambivalent. That attitude did not correspond with the promises the government made to the Nuncio in order to safeguard the legality. In many cases anti-clerical violence was the result of police passivity and it had the complicity of local authorities or groups related to the coalition that supported the government in the Congress.Este artículo analiza el alcance y las características de la violencia anticlerical en los meses de febrero a junio de 1936. Se han rastreado diferentes fuentes primarias para realizar una estadística lo más precisa y completa posible de esa violencia. Primero, se analiza el contexto en el que ésta tuvo lugar. Segundo, se presentan los datos resultantes de la investigación cuantitativa y cualitativa de la violencia anticlerical. Y tercero, se plantea cuál fue la respuesta de las diversas autoridades ante ese fenómeno. El artículo prueba que los datos sobre violencia anticlerical que se han manejado hasta ahora eran fragmentarios y no contemplaban la magnitud ni el carácter general que llegó a alcanzar en los meses inmediatamente anteriores a la Guerra Civil. Además, demuestra que la reacción del gobierno fue, como poco, ambivalente, no correspondiéndose con las promesas

    Full Text Available El tema de este artículo se inscribe en el papel de la televisión como instancia cultural que dispone la formación de valores, actitudes y relaciones sociales de diverso orden. A la televisión se le ha adjudicado un lugar destacado en la aparente “crisis de autoridad” que viven las familias y la sociedad a causa de los contenidos que cuestionan la hegemonía de los adultos como figuras de autoridad. En esta perspectiva, se desarrolló una investigación de diseño mixto que contempló dentro de sus objetivos identificar el consumo televisivo de padres y niños entre 5 y 6 años y las representaciones de autoridad agenciadas por la televisión. Tal indagación se realizó mediante la aplicación de una encuesta a 81 padres de familia de diferentes estratos socioeconómicos de Medellín y Envigado, Colombia. Como conclusión, se destaca el consumo televisivo individualizado de los niños, el exiguo papel orientador de los padres en ello, la recepción de representaciones televisivas que expresan relaciones más simétricas entre padres e hijos y la emergencia de nuevas figuras de poder propias del mundo delictivo, asumidas como figuras de autoridad.

Dos procesos son fundamentales para ubicar la problemática que enfrentan las agencias regulatorias: 1 La hegemonía alcanzada en los 90s por el capital financiero en el sector salud, vía las reformas destinadas a desregularlo; y 2 el reposicionamiento del complejo médico-industrial desde mediados de los 90s, a través de radicalizar la medicalización. Este artículo se basa en varias investigaciones conducidas por la autora en las que se usaron métodos cualitativos y datos secundarios cuantitativos para la contextualización histórico-situacional. El abordaje teórico se basó en Marx, Gramsci, Benasayag, Badiou, Testa y Merhy. El análisis de las reformas más recientes impulsadas por el complejo médico-industrial es producto de una investigación bibliográfica y documental.This article presents the structural processes that consolidated under the hegemony of the financial capital in the 90s; the dispute between the financial capital operating in the health sector and the medical-industrial complex; the strategies used by the medical-industrial complex for regaining positions; and the challenges all these processes pose for the regulatory agencies. The problems the regulatory agencies are facing lie in two central processes: 1 the hegemony the financial capital reached in the 90s in the health sector through reforms aimed at deregulating the sector in order to facilitate its entrance; and 2 the repositioning of the medical-industrial complex since the mid 90s by radicalizing medicalization.

Para poner a prueba estas relaciones múltiples se ha utilizado una muestra de 554 adolescentes de ambos sexos con edades comprendidas entre los 12 y los 16 años. Los datos se recogieron en dos tiempos con un intervalo temporal de 6 meses y se analizaron mediante el cálculo de modelos de ecuaciones estructurales, incluyendo un análisis multigrupo por sexo. Los resultados obtenidos indican que unas relaciones familiares positivas se relacionan con una percepción positiva del ambiente comunitario y actitudes también positivas hacia la autoridad y las normas sociales. Estos factores actúan como una protección frente a la posterior implicación en conductas agresivas hacia los iguales en el contexto escolar y favorecen el bienestar subjetivo. El modelo resultante es equivalente para chicos y chicas.

    Full Text Available El ejercicio de la autoridad sanitaria es un servicio básico de la salud pública. Parte de la responsabilidad de los gestores de la salud pública es hacer cumplir normas. Éstas se desarrollan cuando se dan circunstancias que llevan a considerar inadmisibles ciertos riesgos. El grueso del ejercicio de la autoridad sanitaria se basa en la aplicación relativamente sistemática de normativas detalladas de referencia, aunque siempre hay cierta incertidumbre, ejemplificada en la frecuente adopción de medidas cautelares por un inspector sanitario aplicando el principio de precaución. Pero la vigilancia epidemiológica plantea de forma intermitente situaciones de afectación de la salud humana sin normas de referencia, en las que la autoridad sanitaria debe actuar según su criterio, contrapesando los riesgos de intervenir con los de no actuar. En este manuscrito presentamos 3 casos de este tipo: la coerción en el tratamiento de enfermos con tuberculosis bacilífera; la regulación de actividades con haba de soja que plantean riesgos de asma; y la limitación del ejercicio profesional de un médico infectado por el virus de la inmunodeficiencia humana.Implementing health authority is a basic public health service. Part of the responsibility of public health managers is to ensure compliance with regulations. These are developed when certain risks are considered inadmissible. Mostly, the exercise of health authority deals with the routine application of detailed norms, although there is always some uncertainty, as shown by the frequent use of cautionary measures by health officers during inspections. However, epidemiologic surveillance periodically involves situations in which human health is damaged and there is no reference regulation; in these situations, health authorities must act according to their own criteria, weighing the risks of intervention against those of nonintervention. In this article, we present 3 such scenarios: using coercion

Esta conferencia de Albareda es una muestra de la voluntad de las autoridades científicas españolas para recuperar unas relaciones con la nueva Alemania interrumpidas por los conflictos bélicos, viéndose cuál era la estrategia y la imagen que se intentaba dar al exterior de la tradición científica española, en algunos aspectos muy distante del discurso oficial en el interior del país.

    This study presents a general methodology to the establishment, selection and use of safety indicators for a two loop PWR plant, as Angra 1. The study performed identifies areas considered critical for the plant operational safety. For each of these areas, strategic sub-areas are defined. For each strategic sub-area, specific safety indicators are defined. These proposed Safety Indicators are based on the contribution to risk considering a quantitative risk analysis. For each safety indicator, a goal, a bounded interval and proper bases are developed, to allow for a clear and comprehensive individual behavior evaluation. Additionally, an integrated evaluation of the indicators, using expert systems, was done to obtain an overview of the plant general safety. This methodology can be used for identifying situations where the plant safety is challenged, by giving a general overview of the plant operational condition. Additionally, this study can also identify eventual room for improvements by generating suggestions and recommendations, as a complement for regulatory actions and inspections, focusing resources on eventual existing weaknesses, in order to increase or maintain a high pattern of operational safety.

    The Institute for Radioprotection and Dosimetry - IRD -, of the Brazilian National Nuclear Energy Commission, CNEN, started in 2001, the implementation of a quality management system (SGQ), in the inspection, testing and calibration activities. The SGQ was an institutional guideline and is inserted in a larger system of management of the IRD started in 1999, with the adoption of the National Quality Award criteria - PNQ, within the Project for Excellence in Technological Research of Associacao Brasileira das Instituicoes de Pesquisas Tecnologicas - ABIPTI (Brazilian Association of Technological Research institutions). The proposed quality management system and adopted at the IRD was developed and implemented in accordance with the requirements of NBR ISO/IEC 17025 - General requirements for the competence of testing and calibration laboratories, and ISO/IEC 17020 - General criteria for operation of various types of bodies performing inspections. For regulatory inspection activities, the quality system was implemented on three program inspection services of radiological protection led, respectively, by clinics and hospitals that operate radiotherapy services; industries that use nuclear gauges in their control or productive processes and power reactor operators (CNAAA) - just the environmental part. It was formed a pioneering team of inspectors for standardizing the processes, procedures and starting the implementation of the system in the areas. This work describes the implementation process steps, including difficulties, learning and advantages of the adoption of a quality management system in inspection activities.

    Industrial gammagraphy is a practice widely used as a nondestructive testing technique in Argentina. Experience worldwide has shown the need for an improvement in the intrinsic safety of the equipment used in this lab. In response to this reason, the board of the Nuclear Regulatory Authority (ARN) has considered a proposal to withdraw service movement and much of the equipment inventory scan belonging to industrial facilities nationwide. The main objective of this paper is to present the results of the analysis performed to support the above proposal. The main elements of evaluation can be summarized as follows: I) the teams that do not conform to international recommendations regarding compliance with key safety requirements of international standards such as ISO 3999:2004 (E) {sup R}adiation protection - Industrial Apparatus for gamma radiography - Specifications for performance, design and tests {sup ;} II) the decision by some manufacturers to discontinue production of certain models of equipment and the provision of spare parts, and III) the validity of certificates bulk type B (U) for transport. In conclusion, it highlights the importance of a regulatory decision supplementary to the Standard AR 7.9.1 concerning the operation of scan equipment industry, based on current international recommendations and Argentina's commitment to good practice and safety culture which can lead to a positive impact on radiation safety in this art.

    Full Text Available Es lugar común aceptado entre la sociedad y los profesionales de la comunicación -en todas sus versiones mediáticas- que estos últimos ejercen cierta autoridad en el desempeño de su tarea profesional. Formar parte de una profesión es una especie de reconocimiento social e institucional que se otorga a determinadas personas para administrar un saber específico en beneficio del bien común de la sociedad. Desde una perspectiva epistemológica merece la pena considerar el supuesto de que, en efecto, los comunicadores tengan algún tipo de saber específico -esto es, algún tipo de autoridad sobre el resto-, y preguntarse dónde se encuentra el fundamento de ésta y cómo se ejerce.

En el artículo se estudia el establecimiento, los mandatos y las prácticas de gobierno de las administraciones de Bosnia, Kosovo y Timor Oriental y se identifican cinco fundamentos de la autoridad: el consentimiento, la delegación, el mantenimiento de la paz y la seguridad, el fomento de los derechos humanos y la democracia, y la disposición para gobernar. No obstante, todos estos aspectos son cuestionables. En concreto, la autoridad de las administraciones internacionales se debilita debido a sus prácticas, a que no existe la obligación rendir cuentas y a la efectividad limitada a la hora de disponer gobierno. Para concluir, en el artículo se destacan algunas posibles vías de refuerzo de la autoridad de las administraciones internacionales. In this article there is analyzed how the international administrations that exercise a governmental power in post conflict territories justify their political authority without having democratic legitimacy. In the article it is studied, both the establishment, the mandates and the practices of government of the international administrations of Bosnia, Kosovo and East Timor, and they are identified five sources for this authority: the assent, the delegation, the maintenance of the peace and the safety, the promotion of the human rights and the democracy, and the disposition to govern. Nevertheless, all these aspects are questionable. Concretely, the authority of the international administrations is weakened due to its practices, to the unexistence of any obligation for accountability and to the limited efficiency at the moment of arranging government. To conclude, in the article are outlined some possible ways for the reinforcement of the authority of the international administrations.

De modo que a través de la observación de las tensiones generadas por el uso indiscriminado de la violencia, el desacato y la desobediencia a la autoridad local, se desea mostrar uno de los rostros más violentos que presentaron los procesos de campesinización en Chile durante el periodo colonial, indagando en las formas en que los contemporáneos, la administración y autoridades locales reaccionaron frente a este tipo de prácticas consideradas como intolerables y excesivas. Por supuesto, se pretende dar cuenta delos mecanismos desplegados por controlar ese tipo de conductas y desde ahí profundizar en los horizontes que adoptaron lo justo y la autoridad frente a una cultura popular que se configuró al margen de la “civilidad”.

    Full Text Available Pensar los modos de ejercicio de la autoridad por parte de las mujeres en la policía bonaerense lleva a reflexionar sobre la asociación entre las cualidades y relaciones personales y el poder formalizado puesto en escena en los espacios laborales. Los vínculos, sentimientos y experiencias afectivas introducen orientaciones particulares al devenir de la profesión policial de las personas, especialmente para las mujeres. Ese plus amoroso es vivido, algunas veces, como una obligación personal y, otras, como una estrategia que permite capitalizar las habilidades laborales. El análisis de esta asociación particular es un aporte al estudio de las significaciones y experiencias alrededor de los complejos procesos de ingreso y jerarquización de mujeres en las policías. Porque además de exigir enérgicas adaptaciones a las policías mujeres, provocó modificaciones en la forma de ejercer la profesión más allá del género.

    The results from modern nuclear theory are accurate and reliable enough to be used for practical applications, in particular for scattering that involves few-nucleon systems of importance to nuclear power. Using well-established nucleon-nucleon (NN) interactions that fit well the NN scattering data, and the AGS form of the three-body theory, we have performed precise calculations of low-energy neutron-deuteron (n+d) scattering. We show that three-nucleon force effects that have impact on the low-energy vector analyzing powers have no practical effects on the angular distribution of the n+d cross-section. There appear to be problems for this scattering in the evaluated nuclear data file (ENDF) libraries, at the incident neutron energies less than 3.2 MeV. Supporting experimental data in this energy region are rather old (>25 years), sparse and often inconsistent. Our three-body results at low energies, 50 keV to 10.0 MeV, are compared to the ENDF/B-VII.0 and JENDL (Japanese Evaluated Nuclear Data Library) -3.3 evaluated angular distributions. The impact of these results on the calculated reactivity for various critical systems involving heavy water is shown.

    International cooperation in nuclear industries requires nuclear control as prerequisites. The concept of nuclear control is based on the Treaty on the Non-proliferation of Nuclear Weapon (NPT). The International Atomic Energy Agency (IAEA) plays central role in implementing nuclear control. Nuclear control consists of nuclear safeguards, physical protection, and export/import control. Each member state of NPT is subject to the IAEA`s safeguards by concluding safeguards agreements with the IAEA. IAEA recommends member states to implement physical protection on nuclear materials by `The Physical Protection of Nuclear Material` and `The Convention on the Physical Protection of Nuclear Material` of IAEA. Export/Import Control is to deter development of nuclear weapons by controlling international trade on nuclear materials, nuclear equipments and technology. Current status of domestic and foreign nuclear control implementation including recent induction of national inspection system in Korea is described and functions of recently set-up Technology Center for Nuclear Control (TCNC) under the Korea Atomic Energy Research Institute (KAERI) are also explained. 6 tabs., 11 refs.

    International Nuclear Information System (INIS)

    The Nuclide Dispersion in Phreatic Aquifers (DRAF) model was developed in the 'Division Estudios Ambientales' of the 'Gerencia de Seguridad Radiologica y Nuclear, Comision Nacional de Energia Atomica' (1991), for the Safety Assessment of Near Surface Radioactive Waste Disposal Facilities. Afterwards, it was modified in several opportunities, adapting it to a number of application conditions. The 'Manual del usuario del codigo DRAF' here presented is a reference document for the use of the last three versions of the code developed for the 'Autoridad Regulatoria Nuclear' between 1995 and 1996. The DRAF model solves the three dimension's solute transport equation for porous media by the finite differences method. It takes into account the advection, dispersion, radioactive decay, and retention in the solid matrix processes, and has multiple possibilities for the source term. There are three versions of the model, two of them for the saturated zone and one for the unsaturated zone. All the versions have been verified in different conditions, and have been applied in exercises of the International Atomic Energy Agency and also in real cases. (author)

    International Nuclear Information System (INIS)

    Nuclear forensics is the analysis of nuclear materials recovered from either the capture of unused materials, or from the radioactive debris following a nuclear explosion and can contribute significantly to the identification of the sources of the materials and the industrial processes used to obtain them. In the case of an explosion, nuclear forensics can also reconstruct key features of the nuclear device. Nuclear forensic analysis works best in conjunction with other law enforcement, radiological protection dosimetry, traditional forensics, and intelligence work to provide the basis for attributing the materials and/or nuclear device to its originators. Nuclear forensics is a piece of the overall attribution process, not a stand-alone activity

  16. Nuclear energy and nuclear weapons

    International Nuclear Information System (INIS)

    We all want to prevent the use of nuclear weapons. The issue before us is how best to achieve this objective; more specifically, whether the peaceful applications of nuclear energy help or hinder, and to what extent. Many of us in the nuclear industry are working on these applications from a conviction that without peaceful nuclear energy the risk of nuclear war would be appreciably greater. Others, however, hold the opposite view. In discussing the subject, a necessary step in allaying fears is understanding some facts, and indeed facing up to some unpalatable facts. When the facts are assessed, and a balance struck, the conclusion is that peaceful nuclear energy is much more part of the solution to preventing nuclear war than it is part of the problem

    2009-01-01

    Mutational inactivation of the tumor suppressor gene APC (Adenomatous polyposis coli) is thought to be an initiating step in the progression of the vast majority ofcolorectal cancers. Attempts to understand APC function have revealed more than a dozen binding partners as well as several subcellular localizations including at cell-cell junctions, associated with microtubules at the leading edge of migrating cells, at the apical membrane, in the cytoplasm and in the nucleus. The present chapter focuses on APC localization and functions in the nucleus. APC contains two classical nuclear localization signals, with a third domain that can enhance nuclear import. Along with two sets of nuclear export signals, the nuclear localization signals enable the large APC protein to shuttle between the nucleus and cytoplasm. Nuclear APC can oppose beta-catenin-mediated transcription. This down-regulation of nuclear beta-catenin activity by APC most likely involves nuclear sequestration of beta-catenin from the transcription complex as well as interaction of APC with transcription corepressor CtBP. Additional nuclear binding partners for APC include transcription factor activator protein AP-2alpha, nuclear export factor Crm1, protein tyrosine phosphatase PTP-BL and perhaps DNA itself. Interaction of APC with polymerase beta and PCNA, suggests a role for APC in DNA repair. The observation that increases in the cytoplasmic distribution of APC correlate with colon cancer progression suggests that disruption of these nuclear functions of APC plays an important role in cancer progression. APC prevalence in the cytoplasm of quiescent cells points to a potential function for nuclear APC in control of cell proliferation. Clear definition of APC's nuclear function(s) will expand the possibilities for early colorectal cancer diagnostics and therapeutics targeted to APC. PMID:19928349

    Determination of gamma ray dose in mixed neutron+gamma ray fields is still a demanding task. Dosemeters used for gamma ray dosimetry are usually in some extent sensitive to neutrons and their response variations depend on neutron energy i.e., on neutron spectra. Besides, it is necessary to take into account the energy dependence of dosemeter responses to gamma rays. In this work, several types of thermoluminescent detectors (TLD) placed in different holders used for gamma ray dose determination in the mixed fields were examined. Dosemeters were from three different institutions: Ruder Bosković Institute (RBI), Croatia, JoZef Stefan Institute (JSI), Slovenia and Autoridad Regulatoria Nuclear (ARN), Argentina. All dosemeters were irradiated during the International Intercomparison of Criticality Accident Dosimetry Systems at the SILENE Reactor, Valduc, June 2002. Three accidental scenarios were reproduced and in each irradiation the dosemeters were exposed placed on the front of phantom and 'free in air'. Following types of TLDs were used: 7LiF (TLD-700), CaF2:Mn and Al2O3:Mg,Y-all from RBI; CaF2:Mn from JSI and 7LiF (TLD-700) from ARN. Reported doses were compared with the reference values as well as with the values obtained from the results of all participants. The results show satisfactory agreement with other dosimetry systems used in the Intercomparison. The influence of different types of holders and applied corrections of dosemeters' readings are discussed. PMID:17369267

    Internal dosimetry intercomparisons are essential for the verification of applied models and the consistency of results'. To that aim, the First Regional Intercomparison was organised in 2005, and that results led to the Second Regional Intercomparison Exercise in 2013, which was organised in the frame of the RLA 9/066 and coordinated by Autoridad Regulatoria Nuclear of Argentina. Four simulated cases covering intakes of (131)I, (137)Cs and Tritium were proposed. Ninteen centres from thirteen different countries participated in this exercise. This paper analyses the participants' results in this second exercise in order to test their skills and acquired knowledge, particularly in the application of the IDEAS Guidelines. It is important to highlight the increased number of countries that participated in this exercise compared with the first one and, furthermore, the improvement in the overall performance. The impact of the International Atomic Energy Agency (IAEA) Projects since 2003 has led to a significant enhancement of internal dosimetry capabilities that strengthen the radiation protection of workers.

  4. Nuclear violence

    International Nuclear Information System (INIS)

    A great deal of attention has been paid in the past decade or so to the characteristics of terrorists and their apparent goals and objectives, capabilities, and evolving strategy and tactics with respect to nuclear terrorism. In contrast, little has been said about the procedural aspects of nuclear terrorism, and even less about the way in which such endeavors can fail. This latter omission is important because it bears directly on the ability to evaluate credibly the potential for nuclear terrorism. Here, the author addresses the requirements inherent in acquiring a nuclear explosive capability by three routes: separation of plutonium from irradiated light or heavy water reactor (LWR or HWR) fuel, processing, or use of separated fissile material, and theft of a nuclear weapon. In addition, he deals with other potential acts of nuclear terrorism: sabotage of power reactors, uranium enrichment facilities and spent nuclear fuel in transport, and dispersal of radioactive materials, in particular, plutonium. He specifically does not look at the design or production of a nuclear weapon. Finally, the discussion here assumes that the terrorist is subnational; that is, a nation is not involved. Also, the discussion of subnational participation does not address the possibility of collusion with insiders

Thus, the following pages, will show how two ways were found in order to conceive and solve one same problem. If the friendly indians associated theft with the damage caused to a member of a group by another one, and which therefore required reparation, the provincial authorities considered it an infringement of the law.El trabajo que presentamos se propone mostrar el impacto que tuvo la política porteña entre los indígenas a los que nos referimos atendiendo, especialmente, a los intentos de eliminar o regular los robos cometidos por aquellos. Así, estas páginas ponen en evidencia cómo se encontraron dos maneras de concebir y resolver un mismo problema. Si los indios amigos asociaban el robo a un daño que un miembro del grupo realizaba a otro y que, por lo tanto, requería de una reparación, las autoridades provinciales lo consideraban una infracción a la ley.

  10. Nuclear haematology

    International Nuclear Information System (INIS)

    Nuclear techniques have been applied to study diagnose and treat various haematological disorders for more than five decades. Two scientists are regarded as pioneers in this field, i.e. John Lawrence who in 1938 used 32P to treat chronic myeloid leukaemia and George Hevessy who used 32P labelled erythrocytes to measure blood volume in 1939. At present, many nuclear medicine procedures are available for diagnosis and therapy of a variety of haematological disorders. Although nuclear techniques are somewhat complex, they give direct and quantitative assessment of the kinetics of blood elements as compared to other non-isotopic haematological tests. Basically, equipment required for nuclear haematology is very simple such as well scintillation counters to measure radioactivity in blood samples. More sophisticated equipment like rectilinear scanner or gamma camera is required when imaging is necessary. An overview of the basic principles and clinical applications of nuclear haematology is given

    In this short paper it has only been possible to deal in a rather general way with the standards of safety used in the UK nuclear industry. The record of the industry extending over at least twenty years is impressive and, indeed, unique. No other industry has been so painstaking in protection of its workers and in its avoidance of damage to the environment. Headings are: introduction; how a nuclear power station works; radiation and its effects (including reference to ICRP, the UK National Radiological Protection Board, and safety standards); typical radiation doses (natural radiation, therapy, nuclear power programme and other sources); safety of nuclear reactors - design; key questions (matters of concern which arise in the public mind); safety of operators; safety of people in the vicinity of a nuclear power station; safety of the general public; safety bodies.

    2006-01-01

    The future of nuclear power has returned to centre stage. Freezing weather on both sides of the Atlantic and last month's climate-change talks in Montreal have helped to put energy and the future of nuclear power right back on the political agenda. The issue is particularly pressing for those countries where existing nuclear stations are reaching the end of their lives. In the UK, prime minister Tony Blair has commissioned a review of energy, with a view to deciding later this year whether to build new nuclear power plants. The review comes just four years after the Labour government published a White Paper on energy that said the country should keep the nuclear option open but did not follow this up with any concrete action. In Germany, new chancellor and former physicist Angela Merkel is a fan of nuclear energy and had said she would extend the lifetime of its nuclear plants beyond 2020, when they are due to close. However, that commitment has had to be abandoned, at least for the time being, following negotiations with her left-wing coalition partners. The arguments in favour of nuclear power will be familiar to all physicists - it emits almost no carbon dioxide and can play a vital role in maintaining a diverse energy supply. To over-rely on imported supplies of oil and gas can leave a nation hostage to fortune. The arguments against are equally easy to list - the public is scared of nuclear power, it generates dangerous waste with potentially huge clean-up costs, and it is not necessarily cheap. Nuclear plants could also be a target for terrorist attacks. Given political will, many of these problems can be resolved, or at least tackled. China certainly sees the benefits of nuclear power, as does Finland, which is building a new 1600 MW station - the world's most powerful - that is set to open in 2009. Physicists, of course, are essential to such developments. They play a vital role in ensuring the safety of such plants and developing new types of

    The task of the Expert Committee was to review the technical development and efficacy of nuclear medicine methods and to recommend the best possible means of establishing nuclear medicine services at various levels of medical care in different countries. After reviewing the contributions which nuclear medicine can make, the various types of medical institutions and hospitals in existence, the requirements, organization and funding of nuclear medicine services, and the cost/effectiveness of nuclear medicine, a number of recommendations were made. IAEA and WHO should make information on existing methods of cost/effectiveness analysis widely available; invite governments to include a description of such analysis methods in training programmes of their health officers; assist in the acquisition of the necessary data; and encourage and eventually support actual applications of such analyses to carefully selected nuclear medicine procedures in varying medicosocial environments. They were further recommended to study possible ways of improving reliability and ease of servicing nuclear medicine equipment, and extent of possible local construction; the possibility of making available supplies of matched characterized reagents for radioimmunoassay and related techniques; and to study the advantages of establishing a network of collaborating centres on an international basis

The conventional nuclear potential is characterized as a black box that interpolates nucleon-nucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longer-range parts of the NN force (e.g., OPEP, TPEP, the $\\pi$-$\\gamma$ force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effe...

    The author proposes an overview of methods and concepts used in the nuclear industry, at the design level as well as at the exploitation level, to ensure an acceptable safety level, notably in the case of nuclear reactors. He first addresses the general objectives of nuclear safety and the notion of acceptable risk: definition and organisation of nuclear safety (relationships between safety authorities and operators), notion of acceptable risk, deterministic safety approach and main safety principles (safety functions and confinement barriers, concept of defence in depth). Then, the author addresses the safety approach at the design level: studies of operational situations, studies of internal and external aggressions, safety report, design principles for important-for-safety systems (failure criterion, redundancy, failure prevention, safety classification). The next part addresses safety during exploitation and general exploitation rules: definition of the operation domain and of its limits, periodic controls and tests, management in case of incidents, accidents or aggressions

    Atkins-Duffin, C E

    2008-12-10

    With an explosion equivalent of about 20kT of TNT, the Trinity test was the first demonstration of a nuclear weapon. Conducted on July 16, 1945 in Alamogordo, NM this site is now a Registered National Historic Landmark. The concept and applicability of nuclear power was demonstrated on December 20, 1951 with the Experimental Breeder Reactor Number One (EBR-1) lit four light bulbs. This reactor is now a Registered National Historic Landmark, located near Arco, ID. From that moment forward it had been clearly demonstrated that nuclear energy has both peaceful and military applications and that the civilian and military fuel cycles can overlap. For the more than fifty years since the Atoms for Peace program, a key objective of nuclear policy has been to enable the wider peaceful use of nuclear energy while preventing the spread of nuclear weapons. Volumes have been written on the impact of these two actions on the world by advocates and critics; pundits and practioners; politicians and technologists. The nations of the world have woven together a delicate balance of treaties, agreements, frameworks and handshakes that are representative of the timeframe in which they were constructed and how they have evolved in time. Collectively these vehicles attempt to keep political will, nuclear materials and technology in check. This paper captures only the briefest abstract of the more significant aspects on the Nonproliferation Regime. Of particular relevance to this discussion is the special nonproliferation sensitivity associated with the uranium isotope separation and spent fuel reprocessing aspects of the nuclear fuel cycle.

Under these circumstances it is not difficult to show that on a more quantitative basis, the nuclear industry, in all countries, has an unblemished safety record when compared with other energy sources. Various hazards and benefits of nuclear power are analyzed in this paper comparing with other energy sources. (Liu)

    Nuclear astrophysics is that branch of astrophysics which helps understanding of the Universe, or at least some of its many faces, through the knowledge of the microcosm of the atomic nucleus. It attempts to find as many nuclear physics imprints as possible in the macrocosm, and to decipher what those messages are telling us about the varied constituent objects in the Universe at present and in the past. In the last decades much advance has been made in nuclear astrophysics thanks to the sometimes spectacular progress made in the modelling of the structure and evolution of the stars, in the quality and diversity of the astronomical observations, as well as in the experimental and theoretical understanding of the atomic nucleus and of its spontaneous or induced transformations. Developments in other subfields of physics and chemistry have also contributed to that advance. Notwithstanding the accomplishment, many long-standing problems remain to be solved, and the theoretical understanding of a large variety of observational facts needs to be put on safer grounds. In addition, new questions are continuously emerging, and new facts endangering old ideas. This review shows that astrophysics has been, and still is, highly demanding to nuclear physics in both its experimental and theoretical components. On top of the fact that large varieties of nuclei have to be dealt with, these nuclei are immersed in highly unusual environments which may have a significant impact on their static properties, the diversity of their transmutation modes, and on the probabilities of these modes. In order to have a chance of solving some of the problems nuclear astrophysics is facing, the astrophysicists and nuclear physicists are obviously bound to put their competence in common, and have sometimes to benefit from the help of other fields of physics, like particle physics, plasma physics or solid-state physics.

  10. Nuclear fuel

    International Nuclear Information System (INIS)

    It is expected that nuclear power generation will reach 49 million kW in 1985 and 129 million kW in 1995, and the nuclear fuel having to be supplied and processed will increase in proportion to these values. The technical problems concerning nuclear fuel are presented on the basis of the balance between the benefit for human beings and the burden on the human beings. Recently, especially the downstream of nuclear fuel attracts public attention. Enriched uranium as the raw material for light water reactor fuel is almost monopolized by the U.S., and the technical information has not been published for fear of the diversion to nuclear weapons. In this paper, the present situations of uranium enrichment, fuel fabrication, transportation, reprocessing and waste disposal and the future problems are described according to the path of nuclear fuel cycle. The demand and supply of enriched uranium in Japan will be balanced up to about 1988, but afterwards, the supply must rely upon the early establishment of the domestic technology by centrifugal separation method. No problem remains in the fabrication of light water reactor fuel, but for the fabrication of mixed oxide fuel, the mechanization of the production facility and labor saving are necessary. The solution of the capital risk for the construction of the second reprocessing plant is the main problem. Japan must develop waste disposal techniques with all-out efforts. (Kako, I.)

    Nuclear multifragmentation and spallation reactions produced in medium and high energy collisions are viewed as a percolation phenomenon. Percolation criteria are defined in both real and momentum space and a ''compactness'' condition is imposed to the clusters. Under these conditions, nuclear systems behave like a two-dimensional site percolation model, exhibiting a rather well defined percolation threshold at psub(c) approx.= 0.6. The concentration p is correlated with the number of fast particles ejected in the first stage of the collision. The mass yield results from the superposition of cluster size distributions at different values of p. (orig.)

  8. Nuclear waste

    International Nuclear Information System (INIS)

    DOE estimates that disposing of radioactive waste from civilian nuclear power plants and its defense-related nuclear facilities could eventually end up costing $32 billion. To pay for this, DOE collects fees from utilities on electricity generated by nuclear power plants and makes payments from its defense appropriation. This report states that unless careful attention is given to its financial condition, the nuclear waste program is susceptible to future shortfalls. Without a fee increase, the civilian-waste part of the program may already be underfunded by at least $2.4 billion (in discounted 1988 dollars). Also, DOE has not paid its share of cost-about $480 million-nor has it disclosed this liability in its financial records. Indexing the civilian fee to the inflation rate would address one major cost uncertainty. However, while DOE intends to do this at an appropriate time, it does not use a realistic rate of inflation as its most probable scenario in assessing whether that time has arrived

    1985-01-01

    The question 'Do we really need nuclear power' is tackled within the context of Christian beliefs. First, an estimate is made of the energy requirements in the future and whether it can be got in conventional ways. The dangers of all the ways of supplying energy (eg coal mining, oil and gas production) are considered scientifically. Also the cost of each source and its environmental effects are debated. The consequences of developing a new energy source, as well as the consequences of not developing it, are considered. Decisions must also take into account a belief about the ultimate purpose of life, the relation of men to each other and to nature. Each issue is raised and questions for discussion are posed. On the whole the book comes down in favour of nuclear power.

  12. Nuclear nonproliferation

    International Nuclear Information System (INIS)

    The Department of Energy has taken some actions to implement a 1981 congressional mandate to limit the dissemination of unclassified information related to atomic defense activities. Nevertheless, sensitive countries--communist-controlled nations, countries suspected of developing nuclear weapons, or those viewed as a national security risk--have obtained information dealing with detonators, explosives, and firing sets that could assist or enhance nuclear weapons development. Foreign nationals obtain some information directly from DOE's weapons laboratories; DOE does not require the laboratories to track these requests. DOE recognizes that continuing to disseminate some unclassified information raises questions about its compliance with U.S. nonproliferation policy and in January 1989 issued internal guidance to identify data that should not be distributed to proliferation-risk countries

In the design means are provided for flowing a liquid moderator upwardly through the center of a bed of pellets of a nentron-fissionable material at such a rate as to obtain particulate fluidization while constraining the lower pontion of the bed into a conical shape. A smooth circulation of particles rising in the center and falling at the outside of the bed is thereby established. (AEC)

    The dense neutron-rich matter found in supernovae and neutron stars is expected to form complex nonuniform phases referred to as nuclear pasta. The pasta shapes depend on density, temperature and proton fraction and determine many transport properties in supernovae and neutron star crusts. We use two recently developed hybrid CPU/GPU codes to perform large scale molecular dynamics (MD) simulations with $51200$ and $409600$ nucleons of nuclear pasta. From the output of the MD simulations we characterize the topology and compute two observables, the radial distribution function $g(r)$ and the structure factor $S(q)$, for systems with proton fractions $Y_p=0.10, 0.20, 0.30$ and $0.40$ at about one third of nuclear saturation density and temperatures near $1.0$ MeV. We observe that the two lowest proton fraction systems simulated, $Y_p=0.10$ and $0.20$, equilibrate quickly and form liquid-like structures. Meanwhile, the two higher proton fraction systems, $Y_p=0.30$ and $0.40$, take a longer time to equilibrate a...

  17. Nuclear waste

    International Nuclear Information System (INIS)

    Radioactive waste is mounting at U.S. nuclear power plants at a rate of more than 2,000 metric tons a year. Pursuant to statute and anticipating that a geologic repository would be available in 1998, the Department of Energy (DOE) entered into disposal contracts with nuclear utilities. Now, however, DOE does not expect the repository to be ready before 2010. For this reason, DOE does not want to develop a facility for monitored retrievable storage (MRS) by 1998. This book is concerned about how best to store the waste until a repository is available, congressional requesters asked GAO to review the alternatives of continued storage at utilities' reactor sites or transferring waste to an MRS facility, GAO assessed the likelihood of an MRSA facility operating by 1998, legal implications if DOE is not able to take delivery of wastes in 1998, propriety of using the Nuclear Waste Fund-from which DOE's waste program costs are paid-to pay utilities for on-site storage capacity added after 1998, ability of utilities to store their waste on-site until a repository is operating, and relative costs and safety of the two storage alternatives

O exame de epístolas, crônicas e de outros registros escritos do período revela que os assim chamados "papistas" freqüentemente operavam uma transfiguração da política ao envolvê-la em ancestrais tramas de sentido colhidas junto à tradição letrada eclesiástica. Aspecto exemplificado pela idéia de "desejo", que desponta na documentação quando o historiador volta suas atenções para a investigação dos fundamentos do poder político na civilização medieval. Ela permeia as experiências de autoridade e legitimidade, os posicionamentos acerca do recurso à violência; a crença na hierarquização de poderes. Este breve estudo se detém, portanto, nas imbricadas relações existentes entre a prática do poder, o pensamento político e a linguagem.The theme of this paper is the political vision propagated between the decades of 1060 and 1120 by prominent churchmen engaged in the legitimacy and the exercise of the pontifical power. An examination of epistolae, chronicae and other written records of the period reveal that the so-called "papists" frequently performed a transfiguration of politics by involved it in the ancient webs of meaning conveyed from the ecclesiastical literate tradition. Aspect exemplified by the idea of "desire", which occurs in the historical sources very frequently when the historian turns his attention to investigate the basis of political power in the medieval civilization. It permeates the ideas of authority and legitimacy, the positions about the use of violence and the beliefs in the hierarchy of the powers. Therefore, this brief study aims at the intertwined relationship between the practice of power, political thought and language.

O que se pretende é, entre outras coisas, demonstrar que nem sempre são necessárias reformulações radicais na metodologia do ensino jurídico para que resultados positivos sejam alcançados. Algumas das formas tradicionais de ensino - no caso em questão, os seminários - às vezes não produzem os efeitos desejados, por deficiências no planejamento ou por reproduzirem vícios do ensino jurídico, como: Ensino não participativo; foco no argumento de autoridade; muita exposição e pouco debate; falta de incentivo a posturas críticas etc. A reprodução desses vícios, aliada ao fato de que, nos seminários, muitas vezes o professor está ausente, parece-nos ser a causa da percepção generalizada de que aulas de seminários são uma forma menos importante de aprendizado. Nossa experiência tem demonstrado que esse cenário pode ser muito diferente, se alguns cuidados forem tomados.The aim of this paper is to narrate an experience with participative classes. We argue that radical changes in the current methods of legal education are not always necessary in order to achieve positive outcomes. Sometimes the participative methods already used in brazilian legal education - we focus on seminars - fail to lead to good results either due to deficiencies in planning, or because they tend to replicate the most common problems associated with non-participative methods, such as: Focusing on arguments from authority; excess of lecturing and lack of debate; lack of incentive to critical attitudes, among many others. The replication of these problems, combined with the recurrent absence of the professor responsible for the course, seems to us to be the main cause of the widespread perception that seminars are a method of learning of minor importance. our experience, however, has shown that this scenario may change significantly if due care is exercised.

In the long run even a seeded quantum FEL for {gamma} beams may become possible, with much higher brilliance and spectral flux. At the same time new exciting possibilities open up for focused {gamma} beams. Here we describe a new experiment at the {gamma} beam of the ILL reactor (Grenoble, France), where we observed for the first time that the index of refraction for {gamma} beams is determined by virtual pair creation. Using a combination of refractive and reflective optics, efficient monochromators for {gamma} beams are being developed. Thus, we have to optimize the total system: the {gamma}-beam facility, the {gamma}-beam optics and {gamma} detectors. We can trade {gamma} intensity for band width, going down to {Delta}E{gamma}/E{gamma} Almost-Equal-To 10{sup -6} and address individual nuclear levels. The term 'nuclear photonics' stresses the importance of nuclear applications. We can address with {gamma}-beams individual nuclear isotopes and not just elements like with X-ray beams. Compared to X rays, {gamma} beams can penetrate much deeper into big samples like radioactive waste barrels, motors or batteries. We can perform tomography and microscopy studies by focusing down to {mu}m resolution using Nuclear Resonance Fluorescence (NRF) for detection with eV resolution and high spatial resolution at the same time. We discuss the dominating M1 and E1 excitations like the scissors mode, two-phonon quadrupole octupole excitations, pygmy dipole excitations or giant dipole excitations under the new facet of

    International Nuclear Information System (INIS)

    The joint Department of Energy and Air Force small reactor project was intended to develop a prototype reactor to assess the possibility of using nuclear power to meet the secure power needs of the Air Force. The project ran for a period of 4 years and cost about $3.75 million. Despite the time and money spent, it made little progress towards it intended goal, and the Air Force decided to terminate the project in May 1987. Several problems with DOE's and the Air Force's management of the project contributed to its termination, including (1) the feasibility of using nuclear power that was not clearly established and documented prior to the decision to proceed with the project, (2) disagreements between DOE and the Air Force that contributed to a shifting of responsibility for the project, and (4) an Air Force failure to coordinate its request for project funding with the appropriate congressional committees. The Air Force is now planning another study of energy technologies to identify a potential power source to meet its secure needs. Even today, the Air Force is unsure of the extent of its need

  17. Nuclear regulation

    International Nuclear Information System (INIS)

    Today, 112 nuclear power plants, 22 facilities that support these plants, 54 reactors used in research, and approximately 23,000 organizations hold licenses from either the Nuclear Regulator Commission or various states to use radioactive material; other facilities are operated by various government agencies. Eventually most of these facilities will be decommissioned, which involves removing the radioactive material and terminating the license. NRC needs to ensure that licensees appropriately decontaminate their facilities because, under current regulations, NRC cannot specifically require additional cleanup once it terminates a license. This paper presents a GAO report on NRC's decommissioning procedures. In two of eight cases GAO reviewed, NRC fully or partially released sites for unrestricted use where radioactive contamination was higher than its guidelines allowed; in the other cases, NRC's information was inadequate or incomplete. Further, NRC lacks information on the types and amounts of radioactive waste buried on-site. At five sites reviewed by GAO, groundwater has been found to be contaminated by radioactive waste

    International Nuclear Information System (INIS)

    This thesis deals with two topics in nuclear cardiology. In the first, left ventricular wall motion assessment using Fourier transform of local left ventricular time-activity curves in gated blood pool studies is evaluated. In the second, the interpretation of myocardial perfusion scintigrams is assessed which are obtained with thallium-201 or with another radiopharmaceutical with different physical, but identical biological properties. In all these investigations data acquisition and analysis by computer played an essential role. In chapter 1 the desirable properties of a nuclear medicine computer system are given and the computer system used for this work is described. Wall motion analysis of the left ventricle using Fourier transform of local time-activity curves in the left ventricular region in gated blood pool studies is described in chapter 2. In chapter 3 detection of non-perfused lesions in myocardial perfusion scintigraphy with thallium-201 is described. Detection of partly perfused lesions and the influence of scatter and photon energy on myocardial perfusion scintigraphy is described in chapter 4. (Auth.)

    Background: The dense neutron-rich matter found in supernovae and inside neutron stars is expected to form complex nonuniform phases, often referred to as nuclear pasta. The pasta shapes depend on density, temperature and proton fraction and determine many transport properties in supernovae and neutron star crusts. Purpose: To characterize the topology and compute two observables, the radial distribution function (RDF) g (r ) and the structure factor S (q ) , for systems with proton fractions Yp=0.10 ,0.20 ,0.30 , and 0.40 at about one-third of nuclear saturation density, n =0.050 fm-3 , and temperatures near k T =1 MeV . Methods: We use two recently developed hybrid CPU/GPU codes to perform large scale molecular dynamics (MD) simulations with 51 200 and 409 600 nucleons. From the output of the MD simulations we obtain the two desired observables. Results: We compute and discuss the differences in topology and observables for each simulation. We observe that the two lowest proton fraction systems simulated, Yp=0.10 and 0.20 , equilibrate quickly and form liquidlike structures. Meanwhile, the two higher proton fraction systems, Yp=0.30 and 0.40 , take a longer time to equilibrate and organize themselves in solidlike periodic structures. Furthermore, the Yp=0.40 system is made up of slabs, lasagna phase, interconnected by defects while the Yp=0.30 systems consist of a stack of perforated plates, the nuclear waffle phase. Conclusions: The periodic configurations observed in our MD simulations for proton fractions Yp≥0.30 have important consequences for the structure factors S (q ) of protons and neutrons, which relate to many transport properties of supernovae and neutron star crust. A detailed study of the waffle phase and how its structure depends on temperature, size of the simulation, and the screening length showed that finite-size effects appear to be under control and, also, that the plates in the waffle phase merge at temperatures slightly above 1.0 MeV and

    International Nuclear Information System (INIS)

    The Department of Energy is awarding grants to the state of Nevada for the state's participation in DOE's program to investigate Yucca Mountain as a possible site for the disposal of civilian nuclear waste. This report has found that DOE's financial assistance budget request of $15 million for Nevada's fiscal year 1990 was not based on the amount the state requested but rather was derived by increasing Nevada's grant funds from the previous year in proportion to the increase that DOE requested for its own activities at the Nevada site. DOE's evaluations of Nevada's requests are performed too late to be used in DOE's budget formulation process because Nevada has been applying for financial assistance at about the same time that DOE submits its budget request to Congress

  10. Nuclear exoticism

    Science.gov (United States)

    Penionzhkevich, Yu. E.

    2016-07-01

    Extreme states of nuclearmatter (such that feature high spins, large deformations, high density and temperature, or a large excess of neutrons and protons) play an important role in studying fundamental properties of nuclei and are helpful in solving the problem of constructing the equation of state for nuclear matter. The synthesis of neutron-rich nuclei near the nucleon drip lines and investigation of their properties permit drawing conclusions about the positions of these boundaries and deducing information about unusual states of such nuclei and about their decays. At the present time, experimental investigations along these lines can only be performed via the cooperation of leading research centers that possess powerful heavy-ion accelerators, such as the Large Hadron Collider (LHC) at CERN and the heavy-ion cyclotrons at the Joint Institute for Nuclear Research (JINR, Dubna), where respective experiments are being conducted by physicists from about 20 JINR member countries. The present article gives a survey of the most recent results in the realms of super neutron-rich nuclei. Implications of the change in the structure of such nuclei near the nucleon drip lines are discussed. Information about the results obtained by measuring the masses (binding energies) of exotic nuclei, the nucleon-distribution radii (neutron halo) and momentum distributions in them, and their deformations and quantum properties is presented. It is shown that the properties of nuclei lying near the stability boundaries differ strongly from the properties of other nuclei. The problem of the stability of nuclei that is associated with the magic numbers of 20 and 28 is discussed along with the effect of new magic numbers.

  19. Nuclear husbandry functions

    International Nuclear Information System (INIS)

    Effective and rigorous controls over highly enriched uranium and plutonium, the essential ingredients of nuclear weapons, are critical if we are to reduce nuclear arms, bring a halt to nuclear proliferation, and to avoid large-scale nuclear violence. Currently an unfortunate and simplistic 'one-size-fits-all' attitude about nuclear security is prominent. We have identified seven basic and decidedly distinct nuclear husbandry functions. The analysis leads to some predictions for effective nuclear arms control and nonproliferation, including the idea that domestic nuclear security and safeguards personnel, hardware, approaches, and auditing techniques are not automatically applicable to international arms control efforts.

  4. Nuclear criticality safety at global nuclear fuel

    International Nuclear Information System (INIS)

    Nuclear criticality safety is the art and science of preventing or terminating an inadvertent nuclear chain reaction in non-reactor environment. Nuclear criticality safety as part of integrated safety program in the nuclear industry is the responsibility of regulators, management and operators. Over the past 36 years, Global Nuclear Fuel (GNF) has successfully developed an integrated nuclear criticality safety program for its BWR fuel manufacturing business. Implementation of this NRC-approved program includes three fundamental elements: administrative practices, controls and training. These elements establish nuclear criticality safety function responsibilities and nuclear criticality safety design criteria in accordance with double contingency principle. At GNF, a criticality safety computational system has been integrated into nuclear criticality safety program as an incredibly valuable tool for nuclear criticality safety design and control applications. This paper describes select elements of GNF nuclear criticality safety program with emphasis being placed on need for clear criticality safety function responsibilities, nuclear safety design criteria and associated double contingency implementation, as well as advanced Monte Carlo neutron transport codes used to derive subcritical safety limits.

  7. IAEA and nuclear forensics

    International Nuclear Information System (INIS)

    Nuclear forensics can provide information about the history, intended use and potentially the origin of nuclear or radioactive material. For these reasons, it is an important tool for improving nuclear security and combating illicit trafficking of nuclear and other radioactive materials. The IAEA is currently working on enhancing knowledge, techniques, procedures and cooperation in the field of nuclear forensics. Some of the work currently being undertaken by the IAEA includes the development of a five day training workshop on basic methods for radiological crime scene activities, to ensure adequate control of evidence, including for nuclear forensics purposes, a coordinated research project on the application of nuclear forensics in illicit trafficking, and a proposal for international cooperation with nuclear forensics databases and the development of guidelines for establishing databases. Nuclear forensics will continue to be an important topic for nuclear security and we anticipate that the results of this work will increase State's understanding of and ability to apply nuclear forensics.

  8. Nuclear knowledge management

    International Nuclear Information System (INIS)

    The management of nuclear knowledge has emerged as a growing challenge in recent years. The need to preserve and transfer nuclear knowledge is compounded by recent trends such as ageing of the nuclear workforce, declining student numbers in nuclear-related fields, and the threat of losing accumulated nuclear knowledge. Addressing these challenges, the IAEA promotes a 'knowledge management culture' through: - Providing guidance for policy formulation and implementation of nuclear knowledge management; - Strengthening the contribution of nuclear knowledge in solving development problems, based on needs and priorities of Member States; - Pooling, analysing and sharing nuclear information to facilitate knowledge creation and its utilization; - Implementing effective knowledge management systems; - Preserving and maintaining nuclear knowledge; - Securing sustainable human resources for the nuclear sector; and - Enhancing nuclear education and training

    International Nuclear Information System (INIS)

    According to the author, it remains to be seen whether nuclear disarmament can reduce the risks of nuclear war sufficiently for the residual risks to be acceptable to a majority of the world's population, while at the same time vigorous growth in the world's dependence on nuclear energy for peaceful purposes continues. This paper discusses how use of nuclear materials from dismantled weapons as fuel for peaceful purposes may help progress to be made towards that goal, by stimulating considerable improvements in the effectiveness of arrangements for preventing diversion of the materials from peaceful to military purposes, while at the same time eliminating large numbers of nuclear weapons

  11. Nuclear reactor

    International Nuclear Information System (INIS)

    A nuclear reactor is described in which the core components, including fuel-rod assemblies, control-rod assemblies, fertile rod-assemblies, and removable shielding assemblies, are supported by a plurality of separate inlet modular units. These units are referred to as inlet module units to distinguish them from the modules of the upper internals of the reactor. The modular units are supported, each removable independently of the others, in liners in the supporting structure for the lower internals of the reactor. The core assemblies are removably supported in integral receptacles or sockets of the modular units. The liners, units, sockets and assemblies have inlet openings for entry of the fluid. The modular units are each removably mounted in the liners with fluid seals interposed between the opening in the liner and inlet module into which the fluid enters in the upper and lower portion of the liner. Each assembly is similarly mounted in a corresponding receptacle with fluid seals interposed between the openings where the fluid enters in the lower portion of the receptacle or fitting closely in these regions. As fluid flows along each core assembly a pressure drop is produced along the fluid so that the fluid which emerges from each core assembly is at a lower pressure than the fluid which enters the core assembly. However because of the seals interposed in the mountings of the units and assemblies the pressures above and below the units and assemblies are balanced and the units are held in the liners and the assemblies are held in the receptacles by their weights as they have a higher specific gravity than the fluid. The low-pressure spaces between each module and its liner and between each core assembly and its module is vented to the low-pressure regions of the vessel to assure that fluid which leaks through the seals does not accumulate and destroy the hydraulic balance

  13. Nuclear energy and security

    International Nuclear Information System (INIS)

    Nuclear power is an important and, the authors believe, essential component of a secure nuclear future. Although nuclear fuel cycles create materials that have some potential for use in nuclear weapons, with appropriate fuel cycles, nuclear power could reduce rather than increase real proliferation risk worldwide. Future fuel cycles could be designed to avoid plutonium production, generate minimal amounts of plutonium in proliferation-resistant amounts or configurations, and/or transparently and efficiently consume plutonium already created. Furthermore, a strong and viable US nuclear infrastructure, of which nuclear power is a large element, is essential if the US is to maintain a leadership or even participatory role in defining the global nuclear infrastructure and controlling the proliferation of nuclear weapons. By focusing on new fuel cycles and new reactor technologies, it is possible to advantageously burn and reduce nuclear materials that could be used for nuclear weapons rather than increase and/or dispose of these materials. Thus, the authors suggest that planners for a secure nuclear future use technology to design an ideal future. In this future, nuclear power creates large amounts of virtually atmospherically clean energy while significantly lowering the threat of proliferation through the thoughtful use, physical security, and agreed-upon transparency of nuclear materials. The authors must develop options for policy makers that bring them as close as practical to this ideal. Just as Atoms for Peace became the ideal for the first nuclear century, they see a potential nuclear future that contributes significantly to power for peace and prosperity

    Although nuclear security is a State responsibility, it is nevertheless an international concern, as the consequences of a nuclear security incident would have worldwide impact. These concerns have resulted in the development of numerous international instruments on nuclear security since the terrorist events in the USA on September 11, 2001. The IAEA Office of Nuclear Security has been charged to assist Member States to improvement their nuclear security and to meet the intent of these international obligations in order to ensure a cohesive thread of nuclear security protects the global community. The programs underway and planned by the Office of Nuclear Security will be discussed in this paper. (author)

  1. Potential for nuclear terrorism

    International Nuclear Information System (INIS)

    The question of whether or not terrorists will ''go nuclear'' is discussed. It is possible, although there is no historical evidence that any criminal or terrorist group ever made any attempt to acquire nuclear material for use in an explosive or dispersal device. In terms of intentions, psychotics are potential nuclear terrorists, but in terms of capabilities, they are the farthest away from being able to acquire a nuclear weapon. The history of nuclear incidents in the U.S. and abroad is reviewed. As the nuclear industry expands, the number of low-level incidents (bomb threats, pilferage, etc.) will increase also, but not necessarily escalate to more serious incidents. Terrorists may ''go nuclear'' solely for the publicity value; nuclear hoaxes may be attenpted. Nuclear terrorism seems more attractive as a threat than as an action. But the nature of the threat may change in the future, and the danger of imitation of a successful nuclear terrorist act is pointed out

  2. Nuclear Sphingolipid Metabolism

    Lucki, Natasha C.; Sewer, Marion B.

    2014-01-01

    Nuclear lipid metabolism is implicated in various processes, including transcription, splicing, and DNA repair. Sphingolipids play roles in numerous cellular functions, and an emerging body of literature has identified roles for these lipid mediators in distinct nuclear processes. Different sphingolipid species are localized in various subnuclear domains, including chromatin, the nuclear matrix, and the nuclear envelope, where sphingolipids exert specific regulatory and structural functions. Sphingomyelin, the most abundant nuclear sphingolipid, plays both structural and regulatory roles in chromatin assembly and dynamics in addition to being an integral component of the nuclear matrix. Sphingosine-1-phosphate modulates histone acetylation, sphingosine is a ligand for steroidogenic factor 1, and nuclear accumulation of ceramide has been implicated in apoptosis. Finally, nuclear membrane–associated ganglioside GM1 plays a pivotal role in Ca2+ homeostasis. This review highlights research on the factors that control nuclear sphingolipid metabolism and summarizes the roles of these lipids in various nuclear processes. PMID:21888508

    The change of the position of the State in relation to the economy, although brought the opening of the market to the foreign investments, brought the responsibility of this State in relation to its social aspect. The creation of public policy that could grow the development in the country has been the main goal of the governmental actions, also of its economic planning. This because, when it prevent itself of the direct action in the economy, the State brought for itself the control of some essentials sectors, amongst them the energy sector as well. The energy is a strategical good, the development of a society depends of that, and then, it must be faced as condition to assure the quality of life of the society of direct and indirect form. Therefore the energy is a character of social right, being necessary the implementation of public policies, to not only assure the access of all to the energy, as the rational use of this resource, therefore its it offers assures the independence of a nation in relation to others. It is in this direction that this work searches to analyze the guardianship of the policy of access to the energy by the State, in way this can accomplish the basic objectives of the Constitution, amongst them, the development.

    International Nuclear Information System (INIS)

    This series of slides draws a picture of nuclear engineering training in France. The nuclear sector is very active and developed in France and covers all the aspects of the fuel cycle which implies a strong demand for highly skilled and trained staff. There are both an active involvement of industry in the education process through the design of adequate curricula and a strong support of the State. There are 5 masters dedicated to Science Nuclear Energy (Paris), Nuclear Waste Management (Nantes), Separation Chemistry (Montpellier), Materials for Nuclear Engineering (Grenoble), and 1 engineer degree in nuclear engineering (Saclay). In 2010-2011 there were about 1000 students completing a nuclear energy curriculum (nuclear engineering or specialized nuclear domains) at the master-engineer level throughout France. The detailed curriculum of the Master of Science Nuclear Energy is given. The National Institute of Nuclear Sciences and Techniques (INSTN) plays an important role, it has trained a large fraction of the French leading nuclear practitioners through its 50 years old 'Genie Atomique' curriculum. INSTN proposes also high level courses in nuclear disciplines including training of nuclear physicians, radio-pharmacists and medical physicists and is a major player for continuing education in nuclear sciences.

  12. Global nuclear security engagement

    International Nuclear Information System (INIS)

    Full text: The Nuclear Security Summits in Washington (2010) and Seoul (2012) were convened with the goal of reducing the threat of nuclear terrorism. These meetings have engaged States with established nuclear fuel cycle activities and encouraged their commitment to nuclear security. The participating States have reaffirmed that it is a fundamental responsibility of nations to maintain effective nuclear security in order to prevent unauthorized actors from acquiring nuclear materials. To that end, the participants have identified important areas for improvement and have committed to further progress. Yet, a broader message has emerged from the Summits: effective nuclear security requires both global and regional engagement. Universal commitment to domestic nuclear security is essential, if only because the peaceful use of nuclear energy remains a right of all States: Nations may someday adopt nuclear energy, even if they are not currently developing nuclear technology. However, the need for nuclear security extends beyond domestic power production. To harvest natural resources and to develop part of a nuclear fuel cycle, a State should embrace a nuclear security culture. Nuclear materials may be used to produce isotopes for medicine and industry. These materials are transported worldwide, potentially crossing a nation's borders or passing by its shores. Regrettably, measures to prevent the loss of control may not be sufficient against an adversary committed to using nuclear or other radioactive materials for malicious acts. Nuclear security extends beyond prevention measures, encompassing efforts to detect illicit activities and respond to nuclear emergencies. The Seoul Communique introduces the concept of a Global Nuclear Security Architecture, which includes multilateral instruments, national legislation, best practices, and review mechanisms to promote adoption of these components. Key multilateral instruments include the Convention on Physical Protection of

    2010-07-01

    This nuclear energy roadmap has been prepared jointly by the IEA and the OECD Nuclear Energy Agency (NEA). Unlike most other low-carbon energy sources, nuclear energy is a mature technology that has been in use for more than 50 years. The latest designs for nuclear power plants build on this experience to offer enhanced safety and performance, and are ready for wider deployment over the next few years. Several countries are reactivating dormant nuclear programmes, while others are considering nuclear for the first time. China in particular is already embarking on a rapid nuclear expansion. In the longer term, there is great potential for new developments in nuclear energy technology to enhance nuclear's role in a sustainable energy future.

  2. National Report: Argentina [International Conference on the Safety and Security of Radioactive Sources: Maintaining Continuous Global Control of Sources throughout their Life Cycle, Abu Dhabi (United Arab Emirates), 27-31 October 2013

    International Nuclear Information System (INIS)

    In this report it is intended to describe the status of Argentina in relation to the issues proposed. a) The infrastructure for regulatory control Argentina has a Regulatory Authority, the AUTORIDAD REGULATORIA NUCLEAR (ARN). It is an autonomous body reporting to the President of Argentina. It was created by the “NUCLEAR ACTIVITY NATIONAL ACT”, Nº 24804. This Law empowers ARN to regulate and control the nuclear activity with regard to radiological and nuclear safety, physical protection and nuclear non-proliferation issues. The objective of ARN is to establish, develop and enforce a regulatory system applicable to all nuclear activities carried out in Argentina. ARN is independent, nowadays, of any organization dedicated to the use or the promotion of nuclear energy in any of its forms and is provided with adequate financial resources for the fulfillment of its mission. ARN faculties are: • Issue of regulatory standards: In relation to this subject the most relevant issues to remark during this three years period is that some of the Standards have been updated, on Gammagraphy operation and personnel requirements (2010) AR 7.9.1 and AR 7.11.1 and their regulatory related guidance AR.5; on transport of radioactive material (2012) AR 10.16.1 and generic exemption levels (2010) AR.6. • Grant the corresponding licenses/authorizations to nuclear installations and personnel, including the import export ones. • Grant the corresponding approval Certificates in the case of transport of radioactive material. • Submit requirements to the Responsible Organizations. • Carry out inspections and audits to verify compliance with licenses and authorizations issued and the appropriate Standards. • Perform independent studies and evaluations. • Apply sanctions in the case of non-compliance with any obligation by the license holder. • Approve emergency plans and procedures. • Coordinate the actions in case of radiological/nuclear emergencies.

    2015-10-13

    Recently there has been a lot of interest in small modular reactors. A specific type of these small modular reactors (SMR,) are marine based power plants called floating nuclear power plants (FNPP). These FNPPs are typically built by countries with extensive knowledge of nuclear energy, such as Russia, France, China and the US. These FNPPs are built in one country and then sent to countries in need of power and/or seawater desalination. Fifteen countries have expressed interest in acquiring such power stations. Some designs for such power stations are briefly summarized. Several different avenues for cooperation in FNPP technology are proposed, including IAEA nuclear security (i.e. safeguards), multilateral or bilateral agreements, and working with Russian design that incorporates nuclear safeguards for IAEA inspections in non-nuclear weapons states

  11. Nuclear disarmament verification

    Energy Technology Data Exchange (ETDEWEB)

    DeVolpi, A.

    1993-12-31

    Arms control treaties, unilateral actions, and cooperative activities -- reflecting the defusing of East-West tensions -- are causing nuclear weapons to be disarmed and dismantled worldwide. In order to provide for future reductions and to build confidence in the permanency of this disarmament, verification procedures and technologies would play an important role. This paper outlines arms-control objectives, treaty organization, and actions that could be undertaken. For the purposes of this Workshop on Verification, nuclear disarmament has been divided into five topical subareas: Converting nuclear-weapons production complexes, Eliminating and monitoring nuclear-weapons delivery systems, Disabling and destroying nuclear warheads, Demilitarizing or non-military utilization of special nuclear materials, and Inhibiting nuclear arms in non-nuclear-weapons states. This paper concludes with an overview of potential methods for verification.

  17. Prevention of nuclear war

    International Nuclear Information System (INIS)

    Removing the threat of a nuclear war-as the General Assembly formally stated in the Final Document of its first special session devoted to disarmament, in 1978-is considered to be the task of the present day. In that Document, the General Assembly sought to establish principles, guidelines and procedures for preventing nuclear war. It declared that to that end, it was imperative to remove the threat of nuclear weapons, to halt and reverse the nuclear-arms race until the total elimination of nuclear weapons and their delivery systems had been achieved (see chapter iv), and to prevent the proliferation of nuclear weapons (see chapter VII). At the same time, it called for other measures designed to prevent the outbreak of nuclear war and to lessen the danger of the treat or use of nuclear weapons. The Assembly's clear call for action was dictated by the awareness that there was no insuperable barrier dividing peace from war and that, unless nations brought the spiralling nuclear-arms race to an end, the day might come when nuclear weapons would actually be used, with catastrophic consequences. In adopting the Final Document, the international community achieved, for the first time, a consensus on an international disarmament strategy having as its immediate goal the elimination of the danger of a nuclear war and the implementation of measures to halt and reverse the arms race. The General Assembly, at its second special session on disarmament, in 1982, reaffirmed the validity of the 1978 Final Document. This paper reports that nuclear issues and in particular the prevention of nuclear war remain, however, major concerns of all States. Undoubtedly, all nations have a vital interest in the negotiation of effective measures for her prevention of nuclear war, since nuclear weapons pose a unique threat to human survival. If nuclear war were to occur, its consequences would be global, not simple regional

  1. Relation between nuclear envelope and nuclear lamina in nuclear assembly in vitro

    Institute of Scientific and Technical Information of China (English)

    蔡树涛; 翟中和

    1997-01-01

    Xenopus laevis egg extracts cell-free nuclear assembly system was used as an experimental model to study the process of nuclear lamina assembly in nuclear reconstitution in vitro. The experimental results showed that lamin was involved in the nuclear assembly in vitro. The assembly of nuclear lamina was preceded by the assembly of nuclear matrix, and probably, inner nuclear matrix assembly provided the basis for nuclear lamina assembly. Inhibition of normal assembly of nuclear lamina, by preincubating egg extracts cell-free system with anti-lamin antibodies, resulted in abnormal assembly of nuclear envelope, suggesting that nuclear envelope assembly is closely associated with nuclear lamina assembly.

  5. Polish Nuclear Physics Network

    International Nuclear Information System (INIS)

    In June 2002 the representatives of thirteen Polish nuclear physics units decided to create Polish Nuclear Physics Network (PNPN) and to contact Czech Republic, Hungary and Slovakia with a suggestion to establish a larger network of nuclear physics laboratories in these countries and in Poland. In spring 2003 North-East European Network (NEEN) was established. Its planned networking activities, their objectives and expected outcomes were submitted to EURONS Coordinator. During the same period the nuclear physics laboratories from Bulgaria, Croatia, Greece, Romania, Serbia and Turkey formed South-East European Network (SEEN) and also applied for EURONS support. Eventually, following the EURONS advice, the merge of NEEN and SEEN was decided by representatives of both networks and, in 2004, a common network EWON (East - West Outreach) was included in the EURONS initiative. The indicated EU financial contribution to EWON includes only the support of NEEN, whereas SEEN, for practical reasons, is financed separately. The nuclear physics activity in Poland can be conveniently divided into a few subgroups: - experimental nuclear physics using local facilities; - experimental nuclear physics using external facilities; - theoretical nuclear physics; - applications of nuclear physics to other domains of science; - medical applications. Most of these activities are presented in this report, at least partly, in the form of review articles and short communications. The special place in the Polish nuclear physics landscape occupies the theoretical physics. Not limited by severe financial restrictions which affects local experimental facilities, the flourishing of this domain is especially evident in the nuclear structure theory

  6. History of Nuclear India

    Chaturvedi, Ram

    2000-04-01

    India emerged as a free and democratic country in 1947, and entered into the nuclear age in 1948 by establishing the Atomic Energy Commission (AEC), with Homi Bhabha as the chairman. Later on the Department of Atomic Energy (DAE) was created under the Office of the Prime Minister Jawahar Lal Nehru. Initially the AEC and DAE received international cooperation, and by 1963 India had two research reactors and four nuclear power reactors. In spite of the humiliating defeat in the border war by China in 1962 and China's nuclear testing in 1964, India continued to adhere to the peaceful uses of nuclear energy. On May 18, 1974 India performed a 15 kt Peaceful Nuclear Explosion (PNE). The western powers considered it nuclear weapons proliferation and cut off all financial and technical help, even for the production of nuclear power. However, India used existing infrastructure to build nuclear power reactors and exploded both fission and fusion devices on May 11 and 13, 1998. The international community viewed the later activity as a serious road block for the Non-Proliferation Treaty and the Comprehensive Test Ban Treaty; both deemed essential to stop the spread of nuclear weapons. India considers these treaties favoring nuclear states and is prepared to sign if genuine nuclear disarmament is included as an integral part of these treaties.

  7. Commercial nuclear power 1990

    International Nuclear Information System (INIS)

    This report presents the status at the end of 1989 and the outlook for commercial nuclear capacity and generation for all countries in the world with free market economies (FME). The report provides documentation of the US nuclear capacity and generation projections through 2030. The long-term projections of US nuclear capacity and generation are provided to the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) for use in estimating nuclear waste fund revenues and to aid in planning the disposal of nuclear waste. These projections also support the Energy Information Administration's annual report, Domestic Uranium Mining and Milling Industry: Viability Assessment, and are provided to the Organization for Economic Cooperation and Development. The foreign nuclear capacity projections are used by the DOE uranium enrichment program in assessing potential markets for future enrichment contracts. The two major sections of this report discuss US and foreign commercial nuclear power. The US section (Chapters 2 and 3) deals with (1) the status of nuclear power as of the end of 1989; (2) projections of nuclear capacity and generation at 5-year intervals from 1990 through 2030; and (3) a discussion of institutional and technical issues that affect nuclear power. The nuclear capacity projections are discussed in terms of two projection periods: the intermediate term through 2010 and the long term through 2030. A No New Orders case is presented for each of the projection periods, as well as Lower Reference and Upper Reference cases. 5 figs., 30 tabs

    Stuhrmann, H.B. [GKSS-Forschungszentrum Geesthacht GmbH (Germany)

    1996-11-01

    Polarized neutron scattering from dynamic polarized targets has been applied to various hydrogenous materials at different laboratories. In situ structures of macromolecular components have been determined by nuclear spin contrast variation with an unprecedented precision. The experiments of selective nuclear spin depolarisation not only opened a new dimension to structural studies but also revealed phenomena related to propagation of nuclear spin polarization and the interplay of nuclear polarisation with the electronic spin system. The observation of electron spin label dependent nuclear spin polarisation domains by NMR and polarized neutron scattering opens a way to generalize the method of nuclear spin contrast variation and most importantly it avoids precontrasting by specific deuteration. It also likely might tell us more about the mechanism of dynamic nuclear spin polarisation. (author) 4 figs., refs.

  12. Nuclear insurance fire risk

    International Nuclear Information System (INIS)

    Nuclear facilities operate under the constant risk that radioactive materials could be accidentally released off-site and cause injuries to people or damages to the property of others. Management of this nuclear risk, therefore, is very important to nuclear operators, financial stakeholders and the general public. Operators of these facilities normally retain a portion of this risk and transfer the remainder to others through an insurance mechanism. Since the nuclear loss exposure could be very high, insurers usually assess their risk first-hand by sending insurance engineers to conduct a nuclear insurance inspection. Because a serious fire can greatly increase the probability of an off-site release of radiation, fire safety should be included in the nuclear insurance inspection. This paper reviews essential elements of a facility's fire safety program as a key factor in underwriting nuclear third-party liability insurance. (author)

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

  17. The Nuclear Symmetry Energy

    CERN Document Server

    Baldo, M

    2016-01-01

    The nuclear symmetry energy characterizes the variation of the binding energy as the neutron to proton ratio of a nuclear system is varied. This is one of the most important features of nuclear physics in general, since it is just related to the two component nature of the nuclear systems. As such it is one of the most relevant physical parameters that affect the physics of many phenomena and nuclear processes. This review paper presents a survey of the role and relevance of the nuclear symmetry energy in different fields of research and of the accuracy of its determination from the phenomenology and from the microscopic many-body theory. In recent years, a great interest was devoted not only to the Nuclear Matter symmetry energy at saturation density but also to its whole density dependence, which is an essential ingredient for our understanding of many phenomena. We analyze the nuclear symmetry energy in different realms of nuclear physics and astrophysics. In particular we consider the nuclear symmetry ene...

  18. Training Tomorrow's Nuclear Workforce

    International Nuclear Information System (INIS)

    Training tomorrow's Nuclear Workforce Start with the children. That is the message Brian Molloy, a human resources expert in the IAEA's Nuclear Power Engineering Section, wants to convey to any country considering launching or expanding a nuclear power programme. Mathematics and science curricular and extra-curricular activities at secondary and even primary schools are of crucial importance to future recruiting efforts at nuclear power plants, he says:''You need to interest children in science and physics and engineering. The teaching needs to be robust enough to teach them, but it must also gain their interest.'' Recruiting high-calibre engineers needed for the operation of nuclear power plants is a growing challenge, even for existing nuclear power programmes, because of a wave of retirements combined with increasing global demand. But essential as engineers are, they are only a component of the staff at any nuclear power plant. In fact, most employees at nuclear power plants are not university graduates - they are skilled technicians, electricians, welders, fitters, riggers and people in similar trades. Molloy argues that this part of the workforce needs more focus. ''It's about getting a balance between focusing on the academic and the skilled vocational'', he says, adding that countries considering nuclear power programmes often initially place undue focus on nuclear engineers.

    Nuclear energy already today plays an important role in decarbonisation of the electricity sector while providing energy security and being economically competitive. Nuclear energy is characterized by its very high energy density and is well suited for large-scale, baseload electricity supply. Similar to renewable energy sources such as wind, solar or biomass, nuclear power is characterized by an abundant supply of its primary energy source, uranium, but is not limited to the same extent as these renewable energy sources from being an intermittent energy supply or imposing severe restrictions on land-use. Improving energy efficiency of nuclear power plants has contributed to a better utilization of the uranium resources and has helped improving the economic performance of nuclear power plants. This is to a large degree accomplished through optimisation of nuclear fuel assemblies as well as renewing turbines and generators. More importantly however, the overall economy of nuclear power has improved though better plant management leading to higher capacity factors and by extending the lifetimes of existing nuclear power plants. Provided that improved safety, economics and successful waste management can be demonstrated nuclear power is likely to grow in the future. Non-electricity applications may further boost the growth of nuclear energy, especially with the development of new reactor systems allowing for cogeneration of electricity and hydrogen or biofuels for transport.

  20. Nuclear Energy Data - 2014

    International Nuclear Information System (INIS)

    Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants remained steady in 2013 despite the progressive shutdown of all reactors in Japan leading up to September and the permanent closure of six reactors in the OECD area. Governments committed to maintaining nuclear power in the energy mix advanced plans for increasing nuclear generating capacity, and progress was made in the development of deep geological repositories for spent nuclear fuel, with Finland expected to have the first such facility in operation in the early 2020's. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'StatLinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link. (authors)

  4. Nuclear Technology Review 2014

    International Nuclear Information System (INIS)

    With 434 nuclear power reactors in operation worldwide at the end of 2013, nuclear energy had a global generating capacity of 371.7 GW(e). There were four new grid connections and ten construction starts on new reactors. Belarus became the second nuclear ‘newcomer’ State in three decades to start building its first nuclear power plant. Near and long term growth prospects remained centred in Asia, particularly in China. The 72 reactors under construction in 2013 represented the highest number since 1989. Of these, 48 were in Asia, as were 42 of the last 52 new reactors to have been connected to the grid since 2000. Thirty States currently use nuclear power and about the same number are considering including it as part of their energy mix. Of the 30 States already operating nuclear power plants, 13 are either constructing new plants or actively completing previously suspended constructions, and 12 are planning to either construct new plants or to complete suspended constructions. The IAEA Ministerial Conference on Nuclear Power in the 21st Century, held in June 2013, reaffirmed that nuclear power remains an important option for many States to improve energy security, reduce the impact of volatile fossil fuels prices and mitigate the effects of climate change. The Concluding Statement said that “nuclear power, as a stable base-load source of electricity in an era of ever increasing global energy demands, complements other energy sources including renewables.” In the IAEA’s 2013 projections, nuclear power is expected to grow by between 17% as the low projection and 94% as the high projection by 2030. These figures are slightly lower than projected in 2012, reflecting the continued impact of the Fukushima Daiichi accident, the low prices of natural gas and the increasing use of renewable energy. Additional information focuses on the linkages between nuclear power and climate change, as nuclear power, hydropower and wind energy have the lowest life cycle

  5. Nuclear Energy General Objectives

    International Nuclear Information System (INIS)

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world'. One way it achieves this objective is to issue publications in various series. Two of these series are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III, paragraph A.6, of the IAEA Statute, the IAEA safety standards establish 'standards of safety for protection of health and minimization of danger to life and property.' The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are primarily written in a regulatory style, and are binding on the IAEA for its own activities. The principal users are Member State regulatory bodies and other national authorities. The IAEA Nuclear Energy Series consists of reports designed to encourage and assist research on, and development and practical application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia and politicians, among others. The information is presented in guides, reports on the status of technology and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The series complements the IAEA's safety standards, and provides detailed guidance, experience, good practices and examples on the five areas covered in the IAEA Nuclear Energy Series. The Nuclear Energy Basic Principles is the highest level publication in the IAEA Nuclear Energy Series and describes the rationale and vision for the peaceful uses of nuclear energy. It presents eight Basic Principles on which nuclear energy systems should be based to fulfil nuclear energy's potential to help meet growing global energy needs. The Nuclear Energy Series Objectives are the second level publications. They describe what needs to be

  9. Legislation for nuclear disaster

    International Nuclear Information System (INIS)

    Fukushima nuclear disaster accident clarified problems on nuclear-related legislation and its application. Legislation for nuclear disaster (LNA) could not respond to severe accident because assumed size of accident was not enough. After emergency event corresponding to the article 15 of LNA, was reported by the operator, more than two hours passed by the issuance of Emergency State Declaration. Off-site center could not work at all. This article reviewed outline of LNA and introduced discussion on the reform of legislation and its application. Reform discussion should be focused on swift and effective response readiness to emergency: 1) operator's substantial nuclear emergency drilling, (2) reinforcement of government's headquarters for emergency response, (3) after nuclear emergency, government's headquarters remained to enhance resident's safety from radiation hazard and (4) enactment of nuclear emergency preparedness guidelines for local communities.

    This report summarizes the activities undertaken by EWI while under contract from the Department of Energy (DOE) Office of Nuclear Energy (NE) for the management and operation of the Nuclear Fabrication Consortium (NFC). The NFC was established by EWI to independently develop, evaluate, and deploy fabrication approaches and data that support the re-establishment of the U.S. nuclear industry: ensuring that the supply chain will be competitive on a global stage, enabling more cost-effective and reliable nuclear power in a carbon constrained environment. The NFC provided a forum for member original equipment manufactures (OEM), fabricators, manufacturers, and materials suppliers to effectively engage with each other and rebuild the capacity of this supply chain by : Identifying and removing impediments to the implementation of new construction and fabrication techniques and approaches for nuclear equipment, including system components and nuclear plants. Providing and facilitating detailed scientific-based studies on new approaches and technologies that will have positive impacts on the cost of building of nuclear plants. Analyzing and disseminating information about future nuclear fabrication technologies and how they could impact the North American and the International Nuclear Marketplace. Facilitating dialog and initiate alignment among fabricators, owners, trade associations, and government agencies. Supporting industry in helping to create a larger qualified nuclear supplier network. Acting as an unbiased technology resource to evaluate, develop, and demonstrate new manufacturing technologies. Creating welder and inspector training programs to help enable the necessary workforce for the upcoming construction work. Serving as a focal point for technology, policy, and politically interested parties to share ideas and concepts associated with fabrication across the nuclear industry.

  5. Safety protection of nuclear facilities and nuclear materials

    International Nuclear Information System (INIS)

    Safety protection is discussed of nuclear facilities and of nuclear materials, which is a specific element of guaranteeing nuclear safety. Its task is to maximally restrict the risk of misuse of nuclear facilities and nuclear materials for endangering human lives and health and the environment. Concrete requirements for the barriers and technical means and for security of nuclear facilities and nuclear materials are based on this approach. In the CSSR, a legal norm is being prepared that will enact the said requirements for safety protection of nuclear facilities and nuclear materials. (Z.M.)

  6. The nuclear controversy and nuclear safety techniques

    International Nuclear Information System (INIS)

    Survey interviews with 125 Swedish nuclear safety engineers are summarized and commented upon. A short historical background is given, claiming that the major safety issues of nuclear energy have been debated continously during the 50's and 60's in a way that could well have been watched and interpreted by a political, democratic system involving political parties, government departments, etc. With a few exceptions, these 125 engineers represent 10 - 20 years experience in nuclear research and development. By definition they belong to a professional group of about 800 in Sweden (1978). The main aim of the study is to find out if (how and why) a public debate can bring about changes in an industrially established technology by influencing the attitudes and technical judgements of the individuals and/or organizations involved. Examples are given in which the nuclear specialists themselves admit or claim that direct or indirect impacts from the public debate have been important. A common experience is that the scientists and engineers have been forced to broaden their professional scope through a time-consuming but - on the whole - 'positive' process. A year after the interviews started, a serious reactor accident occured near Harrisburg, Pennsylvania. The group has been used for a survey of the immediate reactions in order to see if it could cause sudden changes of attitudes among the experts. A minority demonstrated clear changes towards a more cautious attitude regarding nuclear risks. (author)

  9. Western Nuclear Science Alliance

    International Nuclear Information System (INIS)

    The Western Nuclear Science Alliance (WNSA) was formed at Oregon State University (OSU) under the DOE Innovations in Nuclear Infrastructure and Education (INIE) program in 2002. The primary objective of the INIE program is to strengthen nuclear science and engineering programs at the member institutions and to address the long term goal of the University Reactor Infrastructure and Education Assistance Program. WNSA has been very effective in meeting these goals. The infrastructure at several of the WNSA university nuclear reactors has been upgraded significantly, as have classroom and laboratory facilities for Nuclear Engineering, Health Physics, and Radiochemistry students and faculty. Major nuclear-related education programs have been inaugurated, including considerable assistance by WNSA universities to other university nuclear programs. Research has also been enhanced under WNSA, as has outreach to pre-college and college students and faculty. The INIE program under WNSA has been an exceptional boost to the nuclear programs at the eight funded WNSA universities. In subsequent years under INIE these programs have expanded even further in terms of new research facilities, research reactor renovations, expanded educational opportunities, and extended cooperation and collaboration between universities, national laboratories, and nuclear utilities.

  13. Nuclear power debate

    International Nuclear Information System (INIS)

    A recent resurgence of interest in Australia in the nuclear power option has been largely attributed to growing concerns over climate change. But what are the real pros and cons of nuclear power? Have advances in technology solved the sector's key challenges? Do the economics stack up for Australia where there is so much coal, gas and renewable resources? Is the greenhouse footprint' of nuclear power low enough to justify its use? During May and June, the AIE hosted a series of Branch events on nuclear power across Sydney, Adelaide and Perth. In the interest of balance, and at risk of being a little bit repetitive, here we draw together four items that resulted from these events and that reflect the opposing views on nuclear power in Australia. Nuclear Power for Australia: Irrelevant or Inevitable? - a summary of the presentations to the symposium held by Sydney Branch on 8 June 2005. Nuclear Reactors Waste the Planet - text from the flyer distributed by The Greens at their protest gathering outside the symposium venue on 8 June 2005. The Case For Nuclear Power - an edited transcript of Ian Hore-Lacy's presentation to Adelaide Branch on 19 May 2005 and to Perth Branch on 28 June 2005.

    While few people now believe that nuclear power would provide ‘power too cheap to meter’, there is still a common perception that nuclear power is a cheap source of electricity. The fact that nuclear power has not come to dominate electricity generation is seen as being due to a combination of public opposition and dealing with the safety issues raised by accidents such as those at Three Mile Island (1978), Chernobyl (1986) and Fukushima (2011). The reality is that nuclear power has seldom be...

    2011-01-01

    We study the nuclear medium effects in the weak structure functions $F_2(x,Q^2)$ and $F_3(x,Q^2)$ in the deep inelastic neutrino/antineutrino reactions in nuclei. We use a theoretical model for the nuclear spectral functions which incorporates the conventional nuclear effects, such as Fermi motion, binding and nucleon correlations. We also consider the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. The calculations have been performed using relativistic nuclear spectral functions which include nucleon correlations. Our results are compared with the experimental data of NuTeV and CDHSW.

  4. European nuclear education network

    International Nuclear Information System (INIS)

    In most countries within the European Union that rely to a significant extent on nuclear power, neither undergraduate nor PhD education is producing a sufficient number of engineers and doctors to fill the needs of the industry. As a result of an EU-supported project, a new education organisation, European Nuclear Education Network (ENEN), has recently been established, with the aim to establish a European master's degree of nuclear engineering. Recently, a new EU project, Nuclear European Platform of Training and University Organisations (NEPTUNO), has been launched, aiming at the practical implementation of ENEN and harmonisation of training activities.

  5. Nuclear fuel lease accounting

    International Nuclear Information System (INIS)

    The subject of nuclear fuel lease accounting is a controversial one that has received much attention over the years. This has occurred during a period when increasing numbers of utilities, seeking alternatives to traditional financing methods, have turned to leasing their nuclear fuel inventories. The purpose of this paper is to examine the current accounting treatment of nuclear fuel leases as prescribed by the Financial Accounting Standards Board (FASB) and the Federal Energy Regulatory Commission's (FERC's) Uniform System of Accounts. Cost accounting for leased nuclear fuel during the fuel cycle is also discussed

  7. Financing a nuclear programme

    International Nuclear Information System (INIS)

    Nuclear power plant construction projects have many characteristics in common with other types of large infrastructure investment, both within the power generation sector and elsewhere. However, nuclear power itself has special features that can make nuclear financing particularly challenging. These features include the high capital cost, the relatively long period required to recoup investments, the often controversial nature of nuclear projects. The need for clear solutions and financing schemes for radioactive waste management and decommissioning and the need for nuclear power plants to operate at high capacity factors, preferably under base load conditions. During the previous major expansion of nuclear power in the 1970 and 1980, many nuclear projects suffered very large construction delays and cost overruns. The legacy of such problems increases the risks perceived by potential investors. A recent study undertaken jointly by the Iea and the Nea showed that the competitiveness of nuclear power strongly depends on the cost of financing due to the high share of fixed capital costs in the total lifetime costs of nuclear power. A key issue in this context is the long-term predictability of carbon pricing arrangements, which, for the time being and despite positive evolutions in this respect, most notably in Europe, does not yet exist. This paper will consider how the risks can be mitigated and examine in detail various models for corporate finance and the role of government assistance in providing a suitable financial basis.

    1990-09-28

    This report presents the status at the end of 1989 and the outlook for commercial nuclear capacity and generation for all countries in the world with free market economies (FME). The report provides documentation of the US nuclear capacity and generation projections through 2030. The long-term projections of US nuclear capacity and generation are provided to the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) for use in estimating nuclear waste fund revenues and to aid in planning the disposal of nuclear waste. These projections also support the Energy Information Administration's annual report, Domestic Uranium Mining and Milling Industry: Viability Assessment, and are provided to the Organization for Economic Cooperation and Development. The foreign nuclear capacity projections are used by the DOE uranium enrichment program in assessing potential markets for future enrichment contracts. The two major sections of this report discuss US and foreign commercial nuclear power. The US section (Chapters 2 and 3) deals with (1) the status of nuclear power as of the end of 1989; (2) projections of nuclear capacity and generation at 5-year intervals from 1990 through 2030; and (3) a discussion of institutional and technical issues that affect nuclear power. The nuclear capacity projections are discussed in terms of two projection periods: the intermediate term through 2010 and the long term through 2030. A No New Orders case is presented for each of the projection periods, as well as Lower Reference and Upper Reference cases. 5 figs., 30 tabs.

  10. Nuclear power in Belgium

    International Nuclear Information System (INIS)

    In the energy sector Belgium is 90% dependent on imports. This was clearly felt by the electricity generating economy when the share of hydrocarbons in the energy resources used for electricity generation increased to more than 85% in 1973 as a consequence of rising electricity consumption. Although Belgium had been early to start employing nuclear power for peaceful purposes, only little use had initially been made of this possibility. After the first oil price crisis the Belgian electricity utilities turned more attention to nuclear power. To this day, seven nuclear power plants have been started up, and Belgian utilities hold a fifty percent share in a French nuclear power plant, while the French EdF holds fifty percent in one Belgian nuclear generating unit. The Belgian nuclear power plants, which were built mostly by Belgian industries, have an excellent operating record. Their availabilities are considerably above the worldwide average and they contributed some 60% to the electricity production in Belgium in 1985. Thanks to nuclear power, the cumulative percentage shares of heating oil and gas in electricity production were reduced to well over 15%, compared to 1973, thus meeting the objectives of using nuclear power, i.e., to save foreign exchange and become self-sufficient in supplying the country's needs. The use of nuclear power allowed the Belgian utilities to reduce the price per kilowatthour of electricity and, in this way, remain competitive with other countries. The introduction of nuclear power continues to have a stabilizing influence on electricity generating costs. In the light of the forecast future development of consumption it is regarded as probable that another nuclear power plant of 1390 MWe will have to be built and commissioned before the year 2000.

  11. Nuclear Safety Review 2013

    International Nuclear Information System (INIS)

    The Nuclear Safety Review 2013 focuses on the dominant nuclear safety trends, issues and challenges in 2012. The Executive Overview provides crosscutting and worldwide nuclear safety information along with a summary of the major sections covered in this report. Sections A-E of this report cover improving radiation, transport and waste safety; strengthening safety in nuclear installations; improving regulatory infrastructure and effectiveness; enhancing emergency preparedness and response (EPR); and civil liability for nuclear damage. The Appendix provides details on the activities of the Commission on Safety Standards (CSS), and activities relevant to the IAEA Safety Standards. The world nuclear community has made noteworthy progress in strengthening nuclear safety in 2012, as promoted by the IAEA Action Plan on Nuclear Safety (hereinafter referred to as ''the Action Plan''). For example, an overwhelming majority of Member States with operating nuclear power plants (NPPs) have undertaken and essentially completed comprehensive safety reassessments ('stress tests') with the aim of evaluating the design and safety aspects of plant robustness to protect against extreme events, including: defence in depth, safety margins, cliff edge effects, multiple failures, and the prolonged loss of support systems. As a result, many have introduced additional safety measures including mitigation of station blackout. Moreover, the IAEA's peer review services and safety standards have been reviewed and strengthened where needed. Capacity building programmes have been built or improved, and EPR programmes have also been reviewed and improved. Furthermore, in 2012, the IAEA continued to share lessons learned from the Fukushima Daiichi accident with the nuclear community including through three international experts' meetings (IEMs) on reactor and spent fuel safety, communication in the event of a nuclear or radiological emergency, and protection against extreme earthquakes and tsunamis

  14. No to nuclear power

    International Nuclear Information System (INIS)

    Kim Beazley has again stated a Labor Government would not pursue nuclear power because the economics 'simply don't stack up'. 'We have significant gas, coal and renewable energy reserves and do not have a solution for the disposal of low-level nuclear waste, let alone waste from nuclear power stations.' The Opposition Leader said developing nuclear power now would have ramifications for Australia's security. 'Such a move could result in our regional neighbours fearing we will use it militarily.' Instead, Labor would focus on the practical measures that 'deliver economic and environmental stability while protecting our national security'. Mr Beazley's comments on nuclear power came in the same week as Prime Minister John Howard declined the request of Indian Prime Minister Manmohan Singh for uranium exports, although seemingly not ruling out a policy change at some stage. The Prime Ministers held talks in New Delhi over whether Australia would sell uranium to India without it signing the Nuclear Non-Proliferation Treaty. An agreement reached during a visit by US President George W. Bush gives India access to long-denied nuclear technology and guaranteed fuel in exchange for allowing international inspection of some civilian nuclear facilities.

  16. Nuclear safety review 1990

    International Nuclear Information System (INIS)

    The Nuclear Safety Review summarizes international developments in nuclear safety and radiation protection that are of importance in keeping nuclear power production and the uses of radiation among the safest of industrial activities. Major political changes in Europe have led to requests from eastern European countries for assistance in reassessing the safety of their nuclear power plants in operation and under construction. For its part in providing such assistance, the IAEA has expanded and extended the various advisory services in nuclear safety and radiation protection that it makes available to its Member States. The accident at the Chernobyl nuclear power plant in 1986 continues to be a primary influence on developments in nuclear safety and radiation protection. Work has been initiated to set up an international research centre in the Chernobyl area for studies relating to the consequences of accidents at nuclear establishments. In the interim, at the request of the USSR, the IAEA has commenced a limited reassessment of the radiological consequences of the Chernobyl accident for the public health and the environment in areas of the three Soviet republics most affected. Four other international organizations are participating in the study. Refs, figs and tabs

  17. High energy nuclear structures

    Energy Technology Data Exchange (ETDEWEB)

    Boguta, J.; Kunz, J.

    1984-03-09

    In conventional nuclear physics the nucleus is described as a non-relativistic many-body system, which is governed by the Schroedinger equation. Nucleons interact in this framework via static two-body potentials, mesonic degrees of freedom are neglected. An alternative description of nuclear physics in terms of a relativistic field theory has been developed by Walecka. The model Lagrangian containing baryons, sigma-mesons and ..omega..-mesons was subsequently extended to include also ..pi..-mesons and rho-mesons. An essential feature of such a nuclear Lagrangian is its renormalizability. In addition to the description of known nuclear structure the field theoretical approach may reveal entirely new nuclear phenomena, based on the explicit treatment of mesonic degrees of freedom. The existence of such abnormal nuclear states was proposed by Lee and Wick employing the sigma-model Lagrangian. There the non-linearity of the meson field equations allows for soliton solutions in the presence of nucleons, in particular the sigma-field may exhibit a kink. Different types of soliton solutions occur in gauge theories with hidden symmetries. In the phenomenological Lagrangian the rho-meson is described by a non-abelian gauge field, that acquires its mass spontaneously due to the non-vanishing vacuum expectation value of a Higgs field. A general ansatz for soliton solutions of such a gauge theory was given by Dashen et al. A specific solution and its possible implications for nuclear physics like anomalous nuclear states were discussed by Boguta.

  2. Nuclear Security Culture Practice

    International Nuclear Information System (INIS)

    Both the human factor and security culture are critical components in ensuring the security of nuclear facilities, infrastructure and transport – their importance cannot be overestimated. To reflect that, the IAEA and international experts have developed the concept of nuclear security culture and its implementing guide, which was published by the IAEA in 2008 under the Nuclear Security Series No. 7. The importance of nuclear security culture has also been recognized by the two nuclear security summits in 2010 and 2012, and included in the final communique and summit recommendations as one of the most important factors. As the next step in promoting and improving nuclear security culture, the IAEA has been working with a group of international experts to develop and implement a robust methodology for self-assessment at nuclear facilities to provide national authorities and facility management with benchmark information on the status of nuclear security culture, and later for the development of a set of measures to fill the identified gaps. The methodology is currently in the final stages of development, and will be brought for IAEA member state review and finalization

  6. Nuclear cardiology in Iran

    International Nuclear Information System (INIS)

    Nuclear cardiology is one of the most active branches of nuclear medicine and plays important role in diagnosis in treatment of CAD patients. Few nuclear cardiology surveys were published in the literature, mostly from developed countries. A nuclear cardiology survey in Iran and analysis of the findings in comparison with other countries may lead to better decision making and improve practice in our country. A questionnaire was sent by mail or e-mail to all nuclear medicine centers in Iran asking for details of nuclear cardiology practice. Also ownership of the centers, number of gamma cameras and number of cardiac studies in each week were recorded. Some centers were studied using telephone interview. From 79 nuclear medicine centers in Iran, 55 centers (69.6%) filled the questionnaire including 28 centers in Tehran and 27 centers in other cities. There was 69 Gamma cameras in these centers, 62.3% with SPECT capability. It is estimated that we may have 100 gamma cameras in Iran. This study showed that about 68287 cardiac studies were done in Iran each year with Myocardial perfusion scan accounting for about 99 2% of the studies. Considering population of the country nuclear cardiology activity will be about 1.05 study/1000/year. Regarding radiotracers used, about 13.5% of studies were done with T I-201, with some centers using only Tc-99m-M I B I

  11. Nucleation of nuclear bodies.

    Science.gov (United States)

    Dundr, Miroslav

    2013-01-01

    The nucleus is a complex organelle containing numerous highly dynamic, structurally stable domains and bodies, harboring functions that have only begun to be defined. However, the molecular mechanisms for their formation are still poorly understood. Recently it has been shown that a nuclear body can form de novo by self-organization. But little is known regarding what triggers the formation of a nuclear body and how subsequent assembly steps are orchestrated. Nuclear bodies are frequently associated with specific active gene loci that directly contribute to their formation. Both coding and noncoding RNAs can initiate the assembly of nuclear bodies with which they are physiologically associated. Thus, the formation of nuclear bodies occurs via recruitment and consequent accumulation of resident proteins in the nuclear bodies by nucleating RNA acting as a seeder. In this chapter I describe how to set up an experimental cell system to probe de novo biogenesis of a nuclear body by nucleating RNA and nuclear body components tethered on chromatin. PMID:23980018

  15. Towards a Nuclear Renaissance

    International Nuclear Information System (INIS)

    With the beginning of the Nuclear Age in the 1950s it was believed that nuclear power could produce electricity in such large amounts and at such a low cost (''too cheap to meter'') that it would become the main energy source. Nuclear power underwent consequently a rapid development during the 1960s and 1970s. This development was brought to a stop in the U.S. following the 1979 Three Mile Island accident and in several Western European countries following the 1986 Chernobyl accident. Nevertheless, nuclear power has been expanding in other regions of the world. mainly in Eastern Europe and in Asia. Globally, the nuclear share of electricity production has remained constant at about 16% since the mid 1980s. However, this share varies widely among the 31 countries that produced nuclear electricity in 2006, ranging from 2% in China to 78% in France, as can be seen in the following figure. It seems that the main factor fueling the renewed interest in nuclear energy in the West is the growing awareness that climate change is very likely caused by combustion of fossil fuels to produce energy. Several other factors concur in recent years to promote a revival of nuclear energy

  1. The nuclear energy debate

    International Nuclear Information System (INIS)

    We have not been able to obtain closure in the nuclear energy debate because the public perception of nuclear energy is out of sync with reality. The industry has not been about to deal with the concerns of those opposed to nuclear energy because its reaction has been to generate and disseminate more facts rather than dealing with the serious moral and ethical questions that are being asked. Nuclear proponents and opponents appeal to different moral communities, and those outside each community cannot concede that the other might be right. The Interfaith Program for Public Awareness of Nuclear Issues (IPPANI) has been formed, sponsored by members of the Jewish, Baha'i, Roman Catholic, United, and Anglican faiths, to provide for a balanced discussion of the ethical aspects of energy.

  2. Axiology of nuclear energy

    International Nuclear Information System (INIS)

    Nuclear energy was born in World War II and it has grown within the regime of Cold War. When the Cold War came to the end around early 1990 s, we who have benefited by the development of nuclear energy must have been challenged with a new tide of civilization change. Although it has not been so much closely questioned since then, such a new movement, that was submerging, abruptly manifested on September 11, 2001. Then, many of us realized that global circumstances, especially concerned with security, must have actually changed with the reordering of the world basic structures. This paper describes on the thoughts to reveal the cause and background of the event on September 11 with the linkage to nuclear energy development, or nuclear civilization in pursuit of the future regime of nuclear in harmonization with the global society in 21st century.

  3. Compensation for nuclear damage

    International Nuclear Information System (INIS)

    To secure fair and efficient compensation for damage likely to be caused by the utilisation of nuclear energy, a special civil liability regime was set up by several international conventions. Three of these conventions are in force and Spain is a Contracting Party to all three. The principles established in the first instance at European level by the Paris Convention (absolute and exclusive liability of the nuclear operator, limitation of such liability, compulsory insurance...) are intended to guarantee that possible victims of a nuclear incident will obtain compensation for damage suffered. The Brussels Convention Supplementary to the Paris Convention provides for official funds to compensate victims through intervention by the Contracting Parties. Each Contracting Party should implement these Conventions at national level by appropriate legislation, which is what Spain did with its Act on Nuclear Energy of 29th April 1964, as supplemented in 1967 by the Regulations on Cover for Nuclear Hazards.

  4. Nuclear Pasta Formation

    CERN Document Server

    Schneider, A S; Hughto, J; Berry, D K

    2013-01-01

    The formation of complex nonuniform phases of nuclear matter, known as nuclear pasta, is studied with molecular dynamics simulations containing 51200 nucleons. A phenomenological nuclear interaction is used that reproduces the saturation binding energy and density of nuclear matter. Systems are prepared at an initial density of 0.10fm$^{-3}$ and then the density is decreased by expanding the simulation volume at different rates to densities of 0.01 fm$^{-3}$ or less. An originally uniform system of nuclear matter is observed to form spherical bubbles ("swiss cheese"), hollow tubes, flat plates ("lasagna"), thin rods ("spaghetti") and, finally, nearly spherical nuclei with decreasing density. We explicitly observe nucleation mechanisms, with decreasing density, for these different pasta phase transitions. Topological quantities known as Minkowski functionals are obtained to characterize the pasta shapes. Different pasta shapes are observed depending on the expansion rate. This indicates non equilibrium effects...

  6. High energy nuclear structures

    International Nuclear Information System (INIS)

    Nuclear field theory has been applied to study nuclear matter as well as finite nuclei. Within the mean field approximation the known bulk properties of nuclei such as binding energy, density, and compressibility are well reproduced. Charge and matter distributions of closed shell nuclei are in good agreement with experimental results, so are rms radii and single-particle energy levels. In addition to the description of known nuclear structure the field theoretical approach may reveal entirely new nuclear phenomena, based on the explicite treatment of mesonic degrees of freedom. The existence of such abnormal nuclear states was proposed by Lee and Wick employing the sigma-model Lagrangian. There the non-linearity of the meson field equations allows for soliton solutions in the presence of nucleons, in particular the sigma-field may exhibit a kink. Some of these solutions are considered

    2016-01-01

    This book focuses on Nuclear-Pumped Laser (NPL) technology and provides the reader with a fundamental understanding of NPLs, a review of research in the field, and exploration of large scale NPL system design and applications. Early chapters look at the fundamental properties of lasers, nuclear-pumping and nuclear reactions that may be used as drivers for nuclear-pumped lasers. The book goes on to explore the efficient transport of energy from the ionizing radiation to the laser medium and then the operational characteristics of existing nuclear-pumped lasers. Models based on Mathematica, explanations and a tutorial all assist the reader’s understanding of this technology. Later chapters consider the integration of the various systems involved in NPLs and the ways in which they can be used, including beyond the military agenda. As readers will discover, there are significant humanitarian applications for high energy/power lasers, such as deflecting asteroids, space propulsion, power transmission and mining....

  13. Nuclear education and international nuclear university

    International Nuclear Information System (INIS)

    In this paper author deals with the concept of establishing the International Nuclear University (INU) would be one of the most viable options. The INU would provide young professionals with not only university-level education but also high-skill training in the fields of nuclear technology. The program will emphasize on global and multi- disciplinary perspectives, which should offer our young generation broader opportunities of advanced education and motivate professional staffs in the enhancement of their knowledge and skills. The 'World Council of Nuclear Education' could be formed to steer the INU for close international cooperation under the auspices of the IAEA. The INU would organize a world network of existing nuclear- related educational organizations and training centers which already exist in Member States. Existing facilities and can be utilized at maximum. Use of cyber-lecturing through Internet, cross-approval of credits among educational organizations in degree work, certification of credits by the authorized body like IAEA, human resources placement services, etc. are some of the activities that the INU could provide in addition to its professional training and higher education.

  14. Nuclear regulation in transition

    International Nuclear Information System (INIS)

    The current state of nuclear regulations in the USA is examined. Since Three Mile Island the regulation of the nuclear power industry has been undergoing a noticeable transition. It will be argued here that the transition is characterized by two indicia. First, the primary focus of state and federal regulators has been on the financial aspects of the industry: this is best seen in the context of decisions allocating the costs of nuclear plant cancellations. Second, decisionmaking power has been decentralized: although the regulatory history of nuclear power demonstrates the tradition of centralized decisionmaking power (i.e., formerly the primary decisionmaking body was the Atomic Energy Commission), now States share decisionmaking power with the Nuclear Regulatory Commission. In Section 1 a brief legislative history of nuclear regulation is presented to establish the assertion that nuclear regulation, both de jure and de facto, was centralized. Next, Section 2 canvasses recent United States Supreme Court opinions regarding nuclear regulation. The Court frequently acts as policymaker through the consequences of its opinions, if not by its intent. In the area of nuclear policymaking, the Court has paid allegiance recently both to the tradition of centralization and to the movement toward decentralization. This dualism is reflected in other federal court decisions as well which will be briefly mentioned. Continuing the analysis of Federal regulation, Section 3 examines the current reform efforts of the NRC. Section 4 presents an examination of State responses to nuclear plant cancellations. In this section, State administrative agency and court decisions will be examined and recent State legislation will be discussed. (author)

  15. Nuclear manpower development

    International Nuclear Information System (INIS)

    The nuclear manpower development project has concentrated on the systemisation and specialization of education and training programs and has actively carried out diverse activities to create new nuclear courses based on the experience of the Nuclear Training and Education Center (NTC) accumulated over the past years. As the demand of education program for training nuclear manpower is increasing due to the remarkable growth of nuclear industry, NTC developed customized education programs making the most use of nuclear experiment equipment and providing practical exercise with research reactor. For improving organizational performance and the development of skilled manpower, KAERI-ACE 2.0 system offered diverse programs addressing the type of occupation and position based on individual competency. Also education on IT was carried out to improve public relations on nuclear and field trips were arranged to encourage local residents' better understanding of the nuclear industry. As a continuous effort, In 2011, NTC specially conducted a survey of employees who are attached to small and medium sized business, and analyzed the present business situations and education requirements for the development of a Pre/under job education program. Prior to this, a briefing session took place for mutual exchange of opinions of industry and academia, based on which a test operation on 'Basic Radiation Education' was carried out. This program has a significance that it was first step toward connection between the nuclear industry and academia as well as an opportunity to educate the employee involved in nuclear engineering field. In 2012, this program is planned to be expanded. With reference to the in-house training, NTC established an 'e-HRD system' providing available resources concerned with education program for cultivating talented personnel. All the education programs are based on individual competency. The e-HRD system will be test operated in 2012 and applied to the

  18. Chinese nuclear insurance and Chinese nuclear insurance pool

    International Nuclear Information System (INIS)

    Chinese Nuclear Insurance Started with Daya Bay Nuclear Power Station, PICC issued the insurance policy. Nuclear insurance cooperation between Chinese and international pool's organizations was set up in 1989. In 1996, the Chinese Nuclear Insurance Pool was prepared. The Chinese Nuclear Insurance Pool was approved by The Chinese Insurance Regulatory Committee in May of 1999. The principal aim is to centralize maximum the insurance capacity for nuclear insurance from local individual insurers and to strengthen the reinsurance relations with international insurance pools so as to provide the high quality insurance service for Chinese nuclear industry. The Member Company of Chinese Nuclear Pool and its roles are introduced in this article

  19. Nuclear generation cost and nuclear research development fund

    International Nuclear Information System (INIS)

    The main objective of this study is to analyze the effects of nuclear R and D fund to nuclear generation cost and to assess the adaptability of fund size through the comparison with the nuclear research fund in Japan. It was estimated that nuclear R and D fund increased the average annual unit cost of nuclear power generation by 1.14 won/kWh. When the size of nuclear R and D fund is compared with that in Japan, this study suggests that the current nuclear R and D fund should be largely increased taking into consideration the ratio of R and D fund to nuclear generation

  7. Advancing against nuclear terrorism

    International Nuclear Information System (INIS)

    Meeting a day before the summit, Bush and Putin announced a new Global Initiative to Combat Nuclear Terrorism; a plan for multiple, multilateral guaranteed suppliers of nuclear fuel to States that forgo building their own enrichment plants; and a Civil Nuclear Agreement that will lift restrictions on cooperation between the two countries in developing peaceful nuclear power. Each of these initiatives provides a framework for dozens of specific actions that can measurably reduce the risk of terrorists acquiring a nuclear weapon. The significance of the Global Initiative against Nuclear Terrorism lies not only in its substance but in Russia's visible joint ownership of the Initiative. After years in which Washington lectured Moscow about this threat, Putin's joint leadership in securing nuclear material worldwide should give added impetus to this undertaking inside Russia as well. Globally, this initiative calls for work plans in five arenas: prevention, detection, disruption, mitigation of consequences after an attack, and strengthening domestic laws and export controls against future A.Q. Khans. The guaranteed nuclear fuel supply tightens the noose around Iran as it seeks to exploit a loophole in the global Nuclear Non-Proliferation Treaty. By guaranteeing States that six separate international suppliers will provide backup guarantees against interruption of supply for any reason other that breech of commitments under the NPT, this proposal eliminates Iran's excuse for Natanz-the enrichment plant it is rushing to finish today. This system for supply will be subject to the supervision by the IAEA, which will also have nuclear fuel reserves that allow it to be a supplier of last resort. The Civil Nuclear Agreement will allow joint research on next-generation, proliferation-proof reactors, including technologies where Russian science is the best in the world. It will permit sale to Russia of US technologies that can improve the safety and efficiency of Russian nuclear

  8. Nuclear law and disorder

    International Nuclear Information System (INIS)

    One would like to say that world attention will be focussed on the 2005 Review Conference of the Nuclear Non-Proliferation Treaty (NPT), that governments will rush to implement the 13 Practical Steps to nuclear disarmament already agreed on, that the combined actions of the political and civil order will greatly reduce the present high level of danger of the use of nuclear weapons. Unfortunately, in the real world of political disorder that we live in, none of this is likely to occur. There is no doubt in my mind that the present crisis is the worst the NPT has experienced. The treaty is on the verge of collapse, and the proliferation of nuclear weapons, both among those who already have them and those who want them, is staring us in the face. It is truly shocking that the public knows so little about the nature of the danger and that governments, for the most part, are so desultory in their approach to the upholding of law. While NPT meetings have never been free of conflict, the battles of the past were frequently patched over by an application of goodwill and a minimum show of trust. Now the goodwill and trust are gone largely because the nuclear-weapons States (NWS) have tried to change the rules of the game. Adherence to that bargain enabled the indefinite extension of the treaty in 1995 and the achievement of an 'unequivocal undertaking' in 2000 toward elimination through a programme of 13 Practical Steps. Now the US is rejecting the commitments of 2000 and premising its aggressive diplomacy on the assertion that the problem of the NPT lies not in the NWS's own actions but in the lack of compliance by States such as North Korea and Iran. Brazil bluntly warned: 'The fulfillment of the 13 steps on nuclear disarmament agreed during the 2000 Review Conference have been significantly - one could even say systematically - challenged by action and omission, and various reservations and selective interpretation by Nuclear Weapon States.' The whole international

    2016-01-01

    We review a semi-microscopic model of nuclear parton distributions, which takes into account a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents and off-shell corrections to bound nucleon distributions as well as nuclear shadowing effect. We also discuss applications of the model to the lepton-nuclear deep-inelastic scattering, Drell-Yan process and neutrino total cross sections.

  11. Nuclear charge and neutron radii and nuclear matter: trend analysis

    CERN Document Server

    Reinhard, P -G

    2016-01-01

    Radii of charge and neutron distributions are fundamental nuclear properties. They depend on both nuclear interaction parameters related to the equation of state of infinite nuclear matter and on quantal shell effects, which are strongly impacted by the presence of nuclear surface. In this work, by studying the dependence of charge and neutron radii, and neutron skin, on nuclear matter parameters, we assess different mechanisms that drive nuclear sizes. We apply nuclear density functional theory using a family of Skyrme functionals obtained by means of different optimization protocols targeting specific nuclear properties. By performing the Monte-Carlo sampling of reasonable functionals around the optimal parametrization, we study correlations between nuclear matter paramaters and observables characterizing charge and neutron distributions. We demonstrate the existence of the strong converse relation between the nuclear charge radii and the saturation density of symmetric nuclear matter and also between the n...

  12. Enhancing operational nuclear safety

    International Nuclear Information System (INIS)

    Since Chernobyl, the dictum An accident anywhere is an accident everywhereis a globally shared perception. The paper presents challenges to the international nuclear community: globalization, sustainable and dynamic development, secure, safe and clean energy supply, nuclear renaissance, public concern for nuclear safety, nuclear security, and technology and management. Strong national safety infrastructures and international cooperation are required to maintain a high level of nuclear safety and security worldwide. There is an increasing number of countries thinking of going nuclear: Morocco, Indonesia, Iran, Poland, Turkey, Bangladesh, Egypt, Vietnam, Chile, Nigeria, Malaysia, Thailand, Uruguay, Tunisia, Algeria. Another serious incident will jeopardize the prospect of nuclear renaissance. Safety and security are preconditions for countries newly introducing NPP as well as for those with mature nuclear programmes. The Global Nuclear Safety Regime (GNSR) is referred to as the institutional, legal and technical framework to achieve worldwide implementation of the safety of nuclear installations. At the top of the framework is the Convention on Nuclear Safety which covers the nuclear power plants. The convention has 56 contracting parties which meet triennially where national reports are presented and subject to the review of peers. The International Atomic Energy Agency (IAEA) undertakes a programme to foster the GNSR through the establishment of IAEA safety standards and related publications. The programme provides for the application of standards for the (1) safety of nuclear installations, (2) safety of radioactive sources, (3) safe transport of radioactive material and (4) management of radioactive waste. It also provides for the security of nuclear installations, nuclear material and radioactive material. The safety standards hierarchy is as follows: safety fundamental, safety requirements and safety guides. The safety fundamentals are the bases for IAEA

  13. Evaluated Nuclear Data

    Energy Technology Data Exchange (ETDEWEB)

    Oblozinsky, P.; Oblozinsky,P.; Herman,M.; Mughabghab,S.F.

    2010-10-01

    This chapter describes the current status of evaluated nuclear data for nuclear technology applications. We start with evaluation procedures for neutron-induced reactions focusing on incident energies from the thermal energy up to 20 MeV, though higher energies are also mentioned. This is followed by examining the status of evaluated neutron data for actinides that play dominant role in most of the applications, followed by coolants/moderators, structural materials and fission products. We then discuss neutron covariance data that characterize uncertainties and correlations. We explain how modern nuclear evaluated data libraries are validated against an extensive set of integral benchmark experiments. Afterwards, we briefly examine other data of importance for nuclear technology, including fission yields, thermal neutron scattering and decay data. A description of three major evaluated nuclear data libraries is provided, including the latest version of the US library ENDF/B-VII.0, European JEFF-3.1 and Japanese JENDL-3.3. A brief introduction is made to current web retrieval systems that allow easy access to a vast amount of up-to-date evaluated nuclear data for nuclear technology applications.

  14. Nuclear physics accelerator facilities

    International Nuclear Information System (INIS)

    The Department of Energy's Nuclear Physics program is a comprehensive program of interdependent experimental and theoretical investigation of atomic nuclei. Long range goals are an understanding of the interactions, properties, and structures of atomic nuclei and nuclear matter at the most elementary level possible and an understanding of the fundamental forces of nature by using nuclei as a proving ground. Basic ingredients of the program are talented and imaginative scientists and a diversity of facilities to provide the variety of probes, instruments, and computational equipment needed for modern nuclear research. Approximately 80% of the total Federal support of basic nuclear research is provided through the Nuclear Physics program; almost all of the remaining 20% is provided by the National Science Foundation. Thus, the Department of Energy (DOE) has a unique responsibility for this important area of basic science and its role in high technology. Experimental and theoretical investigations are leading us to conclude that a new level of understanding of atomic nuclei is achievable. This optimism arises from evidence that: (1) the mesons, protons, and neutrons which are inside nuclei are themselves composed of quarks and gluons and (2) quantum chromodynamics can be developed into a theory which both describes correctly the interaction among quarks and gluons and is also an exact theory of the strong nuclear force. These concepts are important drivers of the Nuclear Physics program

  15. Nuclear forensics: Soil content

    Energy Technology Data Exchange (ETDEWEB)

    Beebe, Merilyn Amy [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2015-08-31

    Nuclear Forensics is a growing field that is concerned with all stages of the process of creating and detonating a nuclear weapon. The main goal is to prevent nuclear attack by locating and securing nuclear material before it can be used in an aggressive manner. This stage of the process is mostly paperwork; laws, regulations, treaties, and declarations made by individual countries or by the UN Security Council. There is some preliminary leg work done in the form of field testing detection equipment and tracking down orphan materials; however, none of these have yielded any spectacular or useful results. In the event of a nuclear attack, the first step is to analyze the post detonation debris to aid in the identification of the responsible party. This aspect of the nuclear forensics process, while reactive in nature, is more scientific. A rock sample taken from the detonation site can be dissolved into liquid form and analyzed to determine its chemical composition. The chemical analysis of spent nuclear material can provide valuable information if properly processed and analyzed. In order to accurately evaluate the results, scientists require information on the natural occurring elements in the detonation zone. From this information, scientists can determine what percentage of the element originated in the bomb itself rather than the environment. To this end, element concentrations in soils from sixty-nine different cities are given, along with activity concentrations for uranium, thorium, potassium, and radium in various building materials. These data are used in the analysis program Python.

  16. Nuclear Information Democratization

    International Nuclear Information System (INIS)

    Nuclear information (Nl) interests people for many reasons, with energy supply, safety, and security being at the top of the list. Democratizing nuclear information has its roots in the growth of a knowledge-based economy, the knowledge worker as a user of nuclear information, developments in information and communication technologies (ICT), and the impact of internet growth. Results of democratization are apparent in the process of information creation, in how nuclear information is distributed and accessed, and in the conditions for using the information found. The International Nuclear Information System (INIS) both reflects and contributes to these trends. Nuclear information falls under the overall umbrella of scientific and technical information (STI). It is highly specialized, but it follows general principles and trends of STI. The world of STI has its own culture and its own long-established rules of use and existence. These have brought us many inventions and improvements, introduced important technological changes, and made our lives and work much easier and more pleasurable. However, the world is constantly changing, and the traditional closed STI environment, including the world of nuclear information, is not keeping up with today’s changes. (author)

  17. Advances in nuclear physics

    CERN Document Server

    Vogt, Erich

    1975-01-01

    Review articles on three topics of considerable current interest make up the present volume. The first, on A-hypernuclei, was solicited by the editors in order to provide nuclear physicists with a general description of the most recent developments in a field which this audience has largely neglected or, perhaps, viewed as a novelty in which a bizarre nuclear system gave some information about the lambda-nuclear intersection. That view was never valid. The very recent developments reviewed here-particularly those pertaining to hypernuclear excitations and the strangeness exchange reactions-emphasize that this field provides important information about the models and central ideas of nuclear physics. The off-shell behavior of the nucleon-nucleon interaction is a topic which was at first received with some embarrassment, abuse, and neglect, but it has recently gained proper attention in many nuclear problems. Interest was first focused on it in nuclear many-body theory, but it threatened nuclear physicists'comf...

  18. Nuclear Material Management Abstract

    International Nuclear Information System (INIS)

    Nevada Test Site (NTS) has transitioned from its historical and critical role of weapons testing to another critical role for the nation. This new role focuses on being a integral element in solving the multiple challenges facing the National Nuclear Security Administration (NNSA) with nuclear material management. NTS is positioned to be a solution for other NNSA sites challenged with safe nuclear materials storage and disposition. NNSA, with site involvement, is currently transforming the nuclear stockpile and supporting infrastructure to meet the 2030 vision. Efforts are under way to consolidate and modernize the production complex . With respect to the nuclear material stockpile, the NNSA sites are currently reducing the complex nuclear material inventory through disposition and consolidation. This includes moving material from other sites to NTS. State of the art nuclear material management and control practices at NTS are essential for NTS to ensure that assigned activities are accomplished in a safe, secure, efficient, and environmentally responsible manner. NTS activities and challenges will be addressed

  19. Application of nuclear models

    International Nuclear Information System (INIS)

    The development of extensive experimental nuclear data base over the past three decades has been accompanied by parallel advancement of nuclear theory and models used to describe and interpret the measurements. This theoretical capability is important because of many nuclear data requirements that are still difficult, impractical, or even impossible to meet with present experimental techniques. Examples of such data needs are neutron cross sections for unstable fission products, which are required for neutron absorption corrections in reactor calculations; cross sections for transactinide nuclei that control production of long-lived nuclear wastes; and the extensive dosimetry, activation, and neutronic data requirements to 40 MeV that must accompany development of the Fusion Materials Irradation Test (FMIT) facility. In recent years systematic improvements have been made in the nuclear models and codes used in data evaluation and, most importantly, in the methods used to derive physically based parameters for model calculations. The newly issued ENDF/B-V evaluated data library relies in many cases on nuclear reaction theory based on compound-nucleus Hauser-Feshbach, preequilibrium and direct reaction mechanisms as well as spherical and deformed optical-model theories. The development and applications of nuclear models for data evaluation are discussed with emphasis on the 1 to 40 MeV neutron energy range

    International Nuclear Information System (INIS)

    MENA region summary: UAE - Ground broken on reactor site; Turkey - Contracts for NPP signed, legal and regulatory infrastructure well-developed; Jordan - Committed plans, NPP procurement process initiated, legal and regulatory infrastructure developing; Egypt - Well-developed plans and legal & regulatory infrastructure, but commitment pending; Saudi Arabia – Commitment made; Algeria, Tunisia - Developing Plans; Kuwait, Oman, Qatar , Bahrain, Morocco - Considered civil nuclear power as an option but no immediate prospects for development. MENA region continues to express strong willingness to diversify its power mix with nuclear and renewables. Gulf States, GCC countries are participating in the collaborative study of a potential nuclear energy programme in the region since 2006. Bahrain, Kuwait, Qatar and Oman are studying the option, however given their small populations and the limited size of their electricity grids, Qatar, Bahrain, and Oman have less capacity to support domestic nuclear power programs. The Fukushima accident has played a role in one country’s decision to abandon nuclear energy for power generation: Kuwaiti government— largely influenced by the events in Japan—decided to reverse its policy on nuclear energy. Valued at US$200 billion, the Middle East’s new nuclear build market holds immense opportunities for expertise, component suppliers and service providers

  1. Evolution of nuclear fuels

    International Nuclear Information System (INIS)

    Nuclear fuel is the primary energy source for sustaining the nuclear fission chain reactions in a reactor. The fuels in the reactor cores are exposed to highly aggressive environment and varieties of advanced fuel materials with improved nuclear properties are continuously being developed to have optimum performance in the existing core conditions. Fabrications of varieties of nuclear fuels used in diverse forms of reactors are mainly based on two naturally occurring nuclear source elements, uranium as fissile 235U and fertile 238U, and thorium as fertile 232Th species. The two metals in the forms of alloys with specific elements, ceramic oxides like MOX and ceramic non-oxide as mixed carbide and nitride with suitable nuclear properties like higher metal density, thermal conductivity, etc. are used as fuels in different reactor designs. In addition, efficiency of various advanced fuels in the forms of dispersion, molten salt and other types are also under investigations. The countries which have large deposits of thorium but limited reserves of uranium, are trying to give special impetus on the development of thorium-based fuels for both thermal and fast reactors in harnessing nuclear energy for peaceful uses of atomic energy.

    It has been well recognized that securing economic viabilities along with technologies are very important elements in the successful implementation of nuclear R and D projects. The objective of the Project is to help nuclear energy to be utilized in an efficient way by analyzing major issues related with nuclear economics. The study covers following subjects: the role of nuclear in the future electric supply system, economic analysis of nuclear R and D project, contribution to the regional economy from nuclear power. In addition, the study introduces the international cooperation in the methodological area of efficient use of nuclear energy by surveying the international activities related with nuclear economics.

  7. Nuclear power for tomorrow

    International Nuclear Information System (INIS)

    The evolution of nuclear power has established this energy source as a viable mature technology, producing at comparative costs more than 16% of the electricity generated world-wide. After outlining the current status of nuclear power, extreme future scenarios are presented, corresponding respectively to maximum penetration limited by technical-economic characteristics, and nuclear phase-out at medium term. The situation is complex and country specific. The relative perception of the importance of different factors and the compensation of advantages vs. disadvantages, or risk vs. benefits, has predominant influence. In order to proceed with an objective and realistic estimate of the future role of nuclear power worldwide, the fundamental factors indicated below pro nuclear power and against are assessed, including expected trends regarding their evolution: Nuclear safety risk; reduction to levels of high improbability but not zero risk. Reliable source of energy; improvements towards uniform standards of excellence. Economic competitiveness vs. alternatives; stabilization and possible reduction of costs. Financing needs and constraints; availability according to requirements. Environmental effects; comparative analysis with alternatives. Public and political acceptance; emphasis on reason and facts over emotions. Conservation of fossil energy resources; gradual deterioration but no dramatic crisis. Energy supply assurance; continuing concerns. Infrastructure requirements and availability; improvements in many countries due to overall development. Non-proliferation in military uses; separation of issues from nuclear power. IAEA forecasts to the year 2005 are based on current projects, national plans and policies and on prevailing trends. Nuclear electricity generation is expected to reach about 18% of total worldwide electricity generation, with 500 to 580 GW(e) installed capacity. On a longer term, to 2030, a stabilized role and place among available viable

  8. Nuclear regulation in 2000

    International Nuclear Information System (INIS)

    A key prerequisite to the development of a nuclear program to provide a country's electricity is that governments and the public are confident that a nuclear accident 'will not occur' over the whole life of the program. This can only be achieved by three elements being equally strong: an excellent design, a highly competent and safety conscious operator, and a strong competent regulator with appropriate legal powers. This paper will outline what is necessary to achieve the third of these prerequisites. It will outline the principles by which a Regulatory Agency ensures that licensees meet their responsibility for the safety of their nuclear plant, based on both internationally accepted ideas, the Nuclear Safety Convention, and Canadian practice. The paper will cover legislative principles -- what to include in legislation, what to include in regulations, and what to include in standards and guides. The problem of 'prescriptive requirements' versus 'general performance statements' in regulations will be addressed, and the implications of this problem on ensuring licensees retain responsibility for safety, and on licensees' desire for a high degree of certainty in what is expected of them, both to get a licence and to keep it, in today's economic climate. The paper will also address compliance and the differences between the lawyers' definition of compliance (meeting specific requirements defined by law) and the nuclear safety engineers' view of compliance, (meeting commitments made at the time a licence was given), and how these views can be reconciled. The paper will discuss how Canada's new Nuclear Safety and Control Act has addressed some of these issues, and how the Canadian Nuclear Safety Commission is implementing the new Act. The issue of transfer of regulatory programs and technology to the regulatory agencies of countries buying a nuclear plant from Canadian companies will be discussed, and examples given of how this has been accomplished to the benefit of

  9. Japan's nuclear dilemma

    International Nuclear Information System (INIS)

    This paper reports that more than any other industrial country, Japan is staking its industrial future on nuclear power. Its 39 commercial reactors generate more than 31,000 megawatts of electricity-supplying more than a quarter of Japan's electricity. By early in the next century, reactors now planned or under construction will bring that figure to near 45,000 megawatts, and half of Japan's electricity will have nuclear origin. These reactors perform as reliably as any in the world: since 1982 Japanese nuclear plants have, on average, operated at above 70 percent of their maximum capacity. Such success with nuclear power is hardly surprising for a technologically advanced country that has virtually no domestic coal or oil. Nuclear power has been Japan's ticket to energy independence. But these glowing statistics may be obscured by a growing cloud. Not only have recent accidents marred a previously excellent safety record and diminished public confidence, but the Japanese nuclear program's guiding vision-the establishment of an indigenous nuclear power supply using breeder reactors and recycled plutonium fuel-is threatened. Many countries -including the United States-made breeders a key part of their nuclear energy strategy in the early 1970s. But most nations have scaled back their breeder plans, for two reasons. First, the fuel they breed in plutonium, which can be directly used to make a nuclear bomb. Second, the economics that once made breeders seem a prudent energy strategy have changed dramatically. With uranium supplies ample and demand slack, the material's cost has dropped and its availability risen; meanwhile, the cost of extracting plutonium from spent fuel has skyrocketed

  10. Virtual nuclear weapons

    Energy Technology Data Exchange (ETDEWEB)

    Pilat, J.F.

    1997-08-01

    The term virtual nuclear weapons proliferation and arsenals, as opposed to actual weapons and arsenals, has entered in recent years the American lexicon of nuclear strategy, arms control, and nonproliferation. While the term seems to have an intuitive appeal, largely due to its cyberspace imagery, its current use is still vague and loose. The author believes, however, that if the term is clearly delineated, it might offer a promising approach to conceptualizing certain current problems of proliferation. The first use is in a reference to an old problem that has resurfaced recently: the problem of growing availability of weapon-usable nuclear materials in civilian nuclear programs along with materials made `excess` to defense needs by current arms reduction and dismantlement. It is argued that the availability of these vast materials, either by declared nuclear-weapon states or by technologically advanced nonweapon states, makes it possible for those states to rapidly assemble and deploy nuclear weapons. The second use has quite a different set of connotations. It is derived conceptually from the imagery of computer-generated reality. In this use, one thinks of virtual proliferation and arsenals not in terms of the physical hardware required to make the bomb but rather in terms of the knowledge/experience required to design, assemble, and deploy the arsenal. Virtual weapons are a physics reality and cannot be ignored in a world where knowledge, experience, materials, and other requirements to make nuclear weapons are widespread, and where dramatic army reductions and, in some cases, disarmament are realities. These concepts are useful in defining a continuum of virtual capabilities, ranging from those at the low end that derive from general technology diffusion and the existence of nuclear energy programs to those at the high end that involve conscious decisions to develop or maintain militarily significant nuclear-weapon capabilities.

    Frois, B.

    2005-04-01

    This paper briefly reviews the next generations of nuclear reactors and the perspectives of development of nuclear energy. Advanced reactors will progressively replace the existing ones during the next two decades. Future systems of the fourth generation are planned to be built beyond 2030. These systems have been studied in the framework of the "Generation IV" International Forum. The goals of these systems is to have a considerable increase in safety, be economically competitive and produce a significantly reduced volume of nuclear wastes. The closed fuel cycle is preferred.

  12. Nuclear public relations campaign

    Energy Technology Data Exchange (ETDEWEB)

    1983-01-01

    A two-day hearing to investigate DOE's participation in a $30 million nuclear public relations program at a time when the country is asked to decrease spending and in conjunction with similar efforts by the nuclear industry focused on the issue of whether ratepayers or shareholders should finance the effort. Shelby Brewer, Assistant Secretary for Nuclear Energy, defended the expenditures as a response to public demand for information and the need to correct misinformation. The testimony of 14 other witnesses includes the views of citizen and professional groups, utilities, and government agencies. Their testimony is followed by additional material submitted for the record. (DCK)

  13. Nuclear matter revisited

    International Nuclear Information System (INIS)

    It is stated that at the Workshop on Nuclear and Dense Matter held at the University of Illinois in May 1977 significant progress was reported that largely resolves many of the questions raised in this journal Vol. 6, p.149, 1976. These include perturbative versus variational methods as applied to nuclear matter, exact solutions for bosons, what is known as the fermion 'homework problem', and various other considerations regarding nuclear matter, including the use of variational methods as opposed to perturbation theory.

    Most elements are synthesized, or ""cooked"", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book

    The debate over the introduction of nuclear power in Australia has recently become more heated in light of safety concerns over the nuclear reactor meltdown emergency in Japan. Australia has also just committed to a carbon trading scheme to address its reliance on coal-fired energy and reduce greenhouse emissions. With 40% of the world's uranium located in Australia, the economic, environmental and health considerations are significant. This book contains an overview of global nuclear energy use and production, and presents a range of current opinions debating the pros and cons of Australia's

    Ron Rosenbaum wants us to be worried. His book How the End Begins: The Road to a Nuclear World War III is intended as an urgent warning that the terrifying dangers of nuclear weapons did not disappear when the Cold War ended two decades ago. There are still many thousands of nuclear weapons in the world—about 95% of them in the U.S. and Russian arsenals—and thousands of them are constantly poised for launch within minutes.

  20. Our nuclear history

    International Nuclear Information System (INIS)

    The article on nuclear history is contained in a booklet on the Revised Nuffield Advanced Physics Course. The author shows how the difficult decisions about energy supplies at the end of the twentieth century can be seen as a consequence of the history and evolution of the Universe and of life, and mankind's activities on earth. The topics discussed include:-the origin of the Universe, formation of light elements, formation of carbon and oxygen, supernovae and nuclear equilibrium, formation of planets, development of life on earth, mankind and the use of fuels, and the nuclear valley.
