    In 2006, the Argentine Nuclear Regulatory Authority has initiated a regulatory knowledge management process to face the loss of knowledge resulting from retiring experts, the generation gap, and the existing need to train new human resources. A number of projects have been started together with the technical assistance of the National Public Administration Institute to preserve knowledge and render it explicit for the coming generations. These projects include 'The History of the Expert's Learning Process' in which the majority of the most critical experts have been interviewed so far. The results of this project help envision a training structure and prospective projects. An Internet Site has also been created on the Intranet in order to render knowledge explicit and facilitate the tools for knowledge management initiatives. Furthermore, ARN's knowledge map project has also been started. (author) [Spanish] La Autoridad Regulatoria Nuclear (ARN), es un Organismo Autarquico de la Administracion Publica Nacional de la Republica Argentina. La puesta en marcha de la gestion del conocimiento en este Organismo responde a la necesidad de no perder los conocimientos de la institucion en el marco del problema del retiro de un numero importante de expertos y de la falta de transmision de sus conocimientos a la nueva generacion. Esta actividad se pone en marcha a traves de programas especificos como entrevistas a expertos retirados y en actividad, la confeccion de un mapa del conocimiento, la identificacion de los conocimientos tacitos y explicitos para su transmision intergeneracional, entre otros, e implica supeditar la estructura tradicional y los procedimientos ya establecidos a los resultados de la misma para cumplir con la mision y vision institucional. Se presentan los objetivos y las caracteristicas del Plan Estrategico de la Institucion, los resultados hasta ahora alcanzados y los desafios a afrontar. (autor)

    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.

    The Argentinean Nuclear Regulation Authority (ARN) verified the existence of changes in the state of some internal components of the reactor of the Atucha I Nuclear Power station that, of continuing in the time, it could take to an inconvenient degradation for the safety operation of the installation. In consequence, to the effects of preventing that reach this situation, at the end of 1999, the ARN required to the Responsible Entity for the operation of this power station the implementation of an important improvements program in the internal components of the reactor. Additionally, and based on the results of the Probabilistic Safety analysis, it was added the one mentioned improvements program the implementation of an alternative cooling system of the reactor core denominated Second Drain of Heat, due to it was determined that, for some accidental sequences, their performance would reduce considerably the probability of damage to the core. The concretion of the improvements program implied to the Responsible Entity the realization of an important quantity of engineering studies, tests and specific inspections that allowed to carry out changes on the control bars of the reactor and its guide tubes; the coolant channels; the sensors of neutron flow; and diverse components of the primary and moderator systems. On the other hand also it was implemented the system Second Drain of Heat, what represents a considerable effort to make compatible the instrumentation and control of last generation, with the instrumentation and existent control systems in the power station. Also, it was requested to be carried out an integrity of the pressure recipient for to demonstrate the existence of an acceptable margin for the difference among the acceptable limit temperatures and of ductile/fragile transition of the material for all the possible accidental scenarios during the useful life of the reactor.

    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)

  17. Autoridade docente: repensar um conceito

    Thiago Miranda dos Santos Moreira

    Full Text Available Resumo Vivemos uma crise de autoridade no mundo moderno e seu impacto no âmbito educacional tem sido objeto de análises e críticas sob diferentes perspectivas. De acordo com Hannah Arendt, esse não é um fenômeno gerado na esfera da educação, não obstante, seu impacto nesse âmbito apareça aos olhos da autora como o sintoma mais evidente da profundidade e seriedade desta crise. Este trabalho tem por objetivo analisar o conceito de autoridade na obra de Hannah Arendt, propondo uma abordagem que busca romper com as perspectivas que veem a autoridade como um epifenômeno do poder. Desse modo, busca-se lançar um olhar sobre a autoridade como um elemento consubstancial à educação e não como um mero instrumento de poder, submissão e sujeição de indivíduos. Assim, num primeiro momento, será apresentada a perspectiva de Alain Renaut, filósofo francês que, em sua abordagem da autoridade, dialoga direta e criticamente com Arendt. Em seguida, será apresentada a origem do conceito sob a perspectiva de Hannah Arendt, bem como sua relação com a educação.

  18. ¿Cómo asegurar calidad regulatoria?

    Bernardo Carvajal Sánchez

    2013-06-01

    Full Text Available La atención de la doctrina administrativista colombiana se ha volcado a dos temas en materia de regulación económica: la noción jurídica de regulación y el órgano regulador. Se descuida así un aspecto central del Derecho contemporáneo de la regulación: la necesidad de asegurar la calidad de la función administrativa de regulación y de las medidas regulatorias actuales y futuras. Este objetivo puede fundarse en razones jurídicas y económicas que exigen la alineación o encuadre del Derecho nacional (duro y blando con la realidad estatal, empresarial y social. Se hace entonces indispensable reflexionar, por un lado, sobre la necesidad de adoptar una política y un modelo regulatorios, basándose en una serie de principios que garanticen tanto la calidad del proceso de expedición como la calidad de la medida adoptada. De otro lado, debe considerarse la necesidad de organizar la gestión de la mejora de la regulación vigente. Este segundo aspecto corresponde a la administración de la reforma y de la evaluación regulatorias, y a la búsqueda del engranaje de esta actividad con las demás políticas y agendas estatales. Cualquier debate teórico y práctico sobre la noción de regulación o sobre el órgano regulador debería inscribirse dentro de esta reflexión transversal, pues ella determina, en últimas, su contexto cognitivo.

    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. In this presentation that is detailed the acted by the Nuclear Regulatory Authority in both cases, the used analysis tools, and the foundation of the adopted decisions. (Author)

  4. Reactors licensing: proposal of an integrated quality and environment regulatory structure for nuclear research reactors in Brazil; Licenciamento de reatores: proposta de uma estrutura regulatoria integrada com abordagem em qualidade e meio ambiente para reatores de pesquisa no Brasil

    2014-07-01

    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.

    2010-09-01

    Full Text Available La quiebra de Lehman Brothers el 15 de septiembre de 2008 marcó un parteaguas en la actual crisis financiera/económica mundial. La decisión de las autoridades estadounidenses de no rescatar el banco ha sido objeto a un gran debate público y académico, pero casi siempre carente de una discusión a profundidad sobre el comportamiento del banco. William Black, un exregulador bancario reconocido por detectar los mayores fraudes durante la crisis bancaria de los Savings & Loan en los años ochenta en los Estados Unidos y uno de los criminólogo financiero más activos en la esfera pública estadounidense, ofrece al lector una visión de los negocios turbios de Lehman Brothers que le llevaron a su colapso. Con el respaldo de documentación pública, Black describe y analiza como Lehman Brothers actuaba como un “vector de fraude”, creando y recreando un ambiente criminal en el sector financiero que castiga al comportamiento honesto y premia el crimen financiero. Ese tema, central al entendimiento de la crisis, a la vez poco reconocido, se expone con la maestría de quien es uno de sus mejores conocedores.

    Before the start up of the RA-0 `zero power` nuclear reactor installed at Cordoba National University, it was necessary to send to the Regulatory Authority the mandatory documentation which is required in the licensing process. With the previous papers existing for the operation in the first years of the `70, a work program for the future operational training personnel was elaborated. Based on the Authority`s applicable rules and the recommendations and with particular criteria originated in the working university conditions, the SAFETY report of RA-0 nuclear reactor was prepared. This paper describes the principal contents, items and documents involved in the safety report. (Author). [Espanol] Con motivo de la nueva puesta en servicio del REACTOR NUCLEAR RA-0 fue necesario elaborar la documentacion mandatoria requerida por la Autoridad Regulatoria Nacional. Siguiendo los lineamientos de las normas y recomendaciones vigentes e incluyendo criterios propios en lo que debia ser el contenido final de dicha documentacion, fue preparado lo que se ha denominado el INFORME DE SEGURIDAD DEL REACTOR NUCLEAR RA-0. Este documento que se describe en este trabajo, si bien contiene las habituales descripciones de todos los Informes de Seguridad, incluye otros aspectos que no siendo requeridos expresamente en el mismo, han dado una mayor coherencia a la conformacion de todos los aspectos que interrelacionan las areas de seguridad fisica, radiologica, nuclear y de control de materiales nucleares bajo salvaguardias.

    Full Text Available La evolución de la medicina occidental desde la Segunda Guerra Mundial ha resultado en la emergencia de nuevas prácticas basadas en la interacción directa entre biología y medicina. El realineamiento de la biología y medicina de la posguerra ha sido acompañada de la emergencia de un nuevo tipo de objetividad, objetividad regulatoria, que ha sido sustentada sobre el recurso a la producción colectiva de la evidencia. A diferencia de las formas de objetividad que emergieron en épocas tempranas, la objetividad regulatoria repercute de manera consistente en la producción de convenciones, algunas veces tácitas y sin intencionalidad, pero recuentemente arriba a través de programas concertados de acción. Las convenciones producidas por la objetividad regulatoria crean las condiciones para una objetividad clínica, que confía en la existencia de entidades y protocolos creados y mantenidos fuera del encuentro íntimo en tre doctor y paciente. Estableciendo formas endógenas de regulación, la objetividad reguladora funciona en un plano y en un modo diferente de aquellos sugeridos por los analistas que tratan toda la regulación como una forma de racionalización impuesta sobre la medicina de fuera.

    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.

    As the result of the existence of several regional delegations all over the country, a requirement was made to conform a secure data interchange structure. This would make possible the interconnection of these facilities and their communication with the Autoridad Regulatoria Nuclear (ARN) headquarters. The records these parts exchange are often of classified nature, including sensitive data by the local safeguards inspectors. On the other hand, the establishment of this network should simplify the access of authorized nuclear and radioactive materials users to the ARN databases, from remote sites and with significant trust levels. These requirements called for a network that should be not only private but also secure, providing data centralization and integrity assurance with a strict user control. The first proposal was to implement a point to point link between the installations. This proposal was deemed as economically not viable, and it had the disadvantage of not being easily reconfigurable. The availability of new technologies, and the accomplishment of the Action Sheet 11 under an agreement between Argentine Nuclear Regulatory Authority and the United States Department of Energy (DOE), opened a new path towards the resolution of this problem. By application of updated tunneling security protocols it was possible to project a manageable and secure network through the use of Virtual Private Networking (VPN) hardware. A first trial installation of this technology was implemented between ARN headquarters at Buenos Aires and the Southern Region Office at Bariloche, Argentina. This private net is at the moment under test, and it is planned to expand to more sites in this country, reaching for example to nuclear power plants. The Bariloche installation had some interesting peculiarities. The solutions proposed to them revealed to be very useful during the development of the network expansion plans, as they showed how to adapt the VPN technical requisites to the

    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) [es

    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 [es

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.

En gran medida esto se debe a que la figura formativa de los padres ha perdido la capacidad poseída en otro tiempo. En relación a esto se explica la influencia de la globalización y las costumbres vividas en muchos hogares y de modo particular el acceso de los niños a las redes sociales. Teniendo en cuenta tal realidad, se analizan desde una óptica filosófico-educativa los modos más adecuados por medio de los cuales los padres podrán recuperar y fortalecer su autoridad formativa, para que mediante su uso consigan que el acceso a las redes sociales contribuya a que los niños se formen alcanzando el equilibrio afectivo y el desarrollo personal necesarios para su vida.

El objetivo del presente estudio fue analizar las diferencias entre chicos y chicas adolescentes en conductas violentas dirigidas hacia sus iguales, y en algunas variables explicativas de estas conductas como sus actitudes hacia la autoridad y las normas, la comunicación con sus padres y la calidad de la relación con sus profesores. Se analizó también en qué medida las relaciones entre estas variables son diferentes en función del sexo. La muestra estuvo compuesta por 663 adolescentes (50.68% chicas, 49.32% chicos entre 12 y 15 años (M = 14.05 y DT = 1.38. Los resultados mostraron puntuaciones superiores en chicos en actitud positiva hacia la transgresión de normas y en violencia directa e indirecta, y superiores en chicas en comunicación abierta con la madre. Los resultados de los análisis de regresión indicaron una importante relación, en chicos y en chicas, entre las actitudes positivas a la transgresión de normas, la comunicación ofensiva con el padre y las conductas violentas directas e indirectas. La comunicación abierta con la madre y las actitudes positivas hacia la autoridad se relacionaron negativamente con la implicación de las chicas en conductas de violencia entre iguales. Estos resultados y sus implicaciones son analizados.

    Full Text Available Colombia es un país conformado política y administrativamente por departamentos, distritos y municipios, sin embargo, las condiciones físicas, de clima, vegetación, recursos naturales, problemáticas ambientales, e incluso la idiosincrasia de sus habitantes, lo convierten en un país de regiones. Por tal motivo, la administración de los recursos naturales renovables, la planificación del crecimiento poblacional, problemas como la diversificación y aumento de los residuos generados, y el manejo, uso y aprovechamiento de los recursos naturales, son fenómenos que exigen autoridades ambientales regionalizadas con autonomía política y administrativa, personería jurídica propia, poderes coercitivos y sancionadores, capacidad de inversión, entre otras características. Este es un trabajo descriptivo, de interpretación y aplicación normativa, y es un aporte para la comprensión de la problemática ambiental regional en Colombia y una herramienta para el conocimiento de las Corporaciones Autónomas Regionales vistas dentro del Sistema Nacional Ambiental (SINA.

    2005-08-01

    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.

    El artículo estudia la política de la iglesia y del estado colonial en sus intentos por cristianizar el ritual funerario de las autoridades étnicas en los Andes peruanos. Desde una perspectiva comparativa, se examina la práctica seguida en dos ciudades del virreinato peruano durante los dos primeros siglos de la colonización española. Se demuestra que las transformaciones operadas fueron producto de políticas de gobierno y evangelización ambivalentes y de estructuras locales de poder.

  17. Pudor, honor, and autoridad: the evolving patient-physician relationship in Spain.

    Science.gov (United States)

    Epstein, R M; Borrell i Carrió, F

    2001-10-01

    The expression of emotion and the sharing of information are determined by cultural factors, consultation time, and the structure of the health care system. Two emblematic situations in Spain - the expression of aggression in the patient-physician encounter, and the withholding of diagnostic information from the patient - have not been well-described in their sociocultural context. To explore these, the authors observed and participated in clinical practice and teaching in several settings throughout Spain and analyzed field notes using qualitative methods. In this paper, we explore three central constructs - modesty (pudor), dignity (honor), and authority (autoridad) - and their expressions in patient-physician encounters. We define two types of emotions in clinical settings - public, extroverted expressions of anger and exuberance; and private, deeply held feelings of fear and grief that tend to be expressed through the arts and religion. Premature reassurance and withholding of information are interpreted as attempts to reconstruct the honor and pudor of the patient. Physician authority and perceived loyalty to the government-run health care system generate conflict and aggression in the patient-physician relationship. These clinical behaviors are contextualized within cultural definitions of effective communication, an ideal patient-physician relationship, the role of the family, and ethical behavior. Despite agreement on the goals of medicine, the behavioral manifestations of empathy and caring in Spain contrast substantially with northern European and North American cultures.

    Full Text Available El trabajo analiza el significado de los emblemas de poder y prestigio usados por las autoridades indígenas durante los siglos XVI y XVII, en el Virreinato del Perú. 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 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.

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.

Este artículo tiene como objetivo estudiar la representación normalizada de los productores archivísticos y la creación de registros de autoridades. El estudio que se presenta es de naturaleza exploratorio – descriptivo; se realiza un análisis teórico sobre la descripción de la entidad productor así como las sub-entidades institución, persona y familia. Se investigan, además, algunas nociones generales sobre registro de autoridad, puntos de acceso y control de autoridades. Finalmente, se presentan las normas internacionales, nacionales y regionales publicadas para la creación de registros de autoridades archivísticas.

This article refutes this theory, proving that the failure of the expedition was the result of its own technical shortcomings and not a consequence of a supposed lack of support on the part of the authorities.Tanto los integrantes de la expedición minera del barón de Nordenflicht como la historiografía tradicional han responsabilizado al virrey Francisco Gil y Lemos (1790-1796 y a las autoridades peruanas del fracaso de la misión.

    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 OBJETIVO: Descrever a organização das autoridades reguladoras nacionais (ARN de medicamentos da Argentina, Brasil, Chile e Peru pela análise de categorias representativas de regras organizacionais. MÉTODOS: As ARN estudadas foram selecionadas utilizando-se os seguintes critérios: estar em país da América do Sul, ter sido identificada como ARN nos Encuentros de Autoridades Competentes en Medicamentos de los Países Iberoamericanos e apresentar boa disponibilidade de dados eletrônicos sobre estrutura e processo da regulação de medicamentos. Como principal fonte de dados, foram consultadas páginas eletrônicas entre maio de 2010 e março de 2011. As categorias analíticas foram: estrutura da organização, competências, direcionalidade e formas de responsabilidade e prestação de contas. RESULTADOS: As ARN da Argentina e do Brasil funcionavam como agências autônomas, enquanto que as do Chile e do Peru se subordinavam diretamente aos respectivos ministérios da saúde. À exceção da ARN brasileira, evidenciou-se a dependência das demais em relação ao ministério para emitir normas sanitárias. O escopo de ação de cada autoridade se diferenciou pelos bens e serviços a ela sujeitos, sendo a do Peru a única dedicada exclusivamente à regulação de medicamentos. As quatro ARN realizam todos os processos apontadas pela Organização Mundial da Saúde como essenciais para uma regulação efetiva. CONCLUSÕES: Os resultados apontam para um esforço dos países estudados em melhorar sua estrutura regulatória. Não obstante, em diversos aspectos, as quatro ARN ainda precisam aprimorar mecanismos para garantir, ao final da cadeia regulatória, a qualidade e a segurança dos medicamentos por elas regulados, com mais transparência nos processos decisórios e prestação de contas à sociedade.

    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.

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.

    Richard Pace

    Full Text Available Os 'caboclos' da Amazônia brasileira estão classificados variavelmente como camponeses, extratores, povo rústico e descendentes miscigenados de europeus, indígenas e africanos. Em quase todos os usos se reconhece um tom pejorativo e raramente usado para chamar uma pessoa do mesmo nível social. As poucas pessoas que se identificam como 'caboclo' usam a palavra para referir-se a si mesmos, a não ser em condições especiais. Aceita-se que uma das finalidades das ciências sociais, particularmente a antropologia, é entender todas as culturas no mesmo nível e dar-lhes a mesma integridade que damos a nossa. Por que, então, insistimos em usar este termo? Esta pesquisa examina esta dúvida através da discussão sobre a representação e o uso de autoridade na documentação etnográfica

    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.

    Full Text Available Las vacilaciones con las que se procedió a la realización de las reformas fiscales en el Reino de Valencia tras la abolición de los fueros en 1707 generaron numerosos conflictos que impulsaron a la Monarquía a reforzar la autoridad del intendente. Con tal finalidad, se potenció la tramitación por la vía reservada de las decisiones que adoptaba en materia hacendística. Pero el considerable incremento de su poder que ello comportó favoreció su utilización de forma abusiva en beneficio propio o de la red clientelar articulada a su alrededor. No obstante, las relaciones que mantenía el intendente con las élites locales contribuyen a explicar el eco desigual que alcanzaron las denuncias de corrupción que se formularon a lo largo de la centuria.AbstractThe hesitant application of the fiscal reforms implemented in the Kingdom of Valencia after the abolition of the regional laws in 1707 generated many conflicts that drove the Monarchy to reinforce the authority of the intendant. With this purpose, the Monarchy encouraged the reserved direct processing of the decisions adopted in financial matter. However, this caused a considerable increase of the intendant power that also implied the abusive usage for its own or the client network’s profit surrounding its figure. Nevertheless, the intendant relationships with the local elites explain the corruption accusations’ unequal eco throughout the century.

    Full Text Available Las modalidades institucionales para la prestación de los servicios de acueducto y saneamiento básico en el país, han presentado importantes transformaciones en la última década, como resultado de la Constitución Política de 1991 y la Ley 142 de 1994 o Ley de Servicios Públicos Domiciliarios. Sin embargo, la situación de los pequeños municipios del país, en relación conla prestación de los servicios públicos y la calidad de éstos, deja ver las carencias normativas y estructurales en el sector. Este artículo presenta una serie de propuestas de reformas institucionales, legislativas y regulatorias, que pretende ser un medio para facilitar avances relevantes en el sector, sobre todo en los municipios de la «Otra Colombia». Concretamente, las recomendaciones se enmarcan dentro de cinco ejes temáticos: 1 gestión de los prestadores del sector; 2 regulación económica; 3 financiamiento; 4 control social; y 5 ambiente.

Se busca analizar esta relación de manera crítica desde los discursos ideológicos que se producen para el abordaje de estas categorías, a fin de contribuir con este pensar. El ensayo da cuenta desde lo cotidiano de la escuela, el tema de la autoridad en su relación con la transmisión, lo que conduce a recibir una atención permanente por parte de la comunidad académica como objeto de investigación. La autoridad escolar, producida a partir de las experiencias históricas escolares, se viene asumiendo como tal debido a la manera intensa y conflictiva dentro de los espacios de formación, siendo, que este problema, reproduce mecánicamente formas excluyentes y reduccionistas por parte de la autoridad docente. AbstractThis essay is made in order to reflect about the authority and transmission within formation sceneries, which becomes into some theoretical notes to rethink education, such as the pedagogical action and the current commitment in these sceneries to fight against authoritary forms which prevent autonomy thinking.

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.

    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.

    Full Text Available The Relation between the State’s Capacity and Authority: The Construction of an ‘Exceptionalist State’In this paper we posit that the trajectory of structural-economic transformations in Ecuador between 2008 and 2014 can be understood from the perspective of state theory. Specifically, we argue that strengthening state authority in Ecuador has come at the expense of state capacities: by positioning the state in a place of ‘exceptional authority’, governmental actions sidelined the development of formal and informal networks between state and non-state actors, such as industrialists. Furthermore, we show that state capacities have been further undermined by internal divisions within bureaucratic structures and an eclectic process of leadership formation at the level of the state’s bureaucracy. Combined, these processes have resulted in a hybrid state form: a state with high degrees of authority that coexist with low levels of institutional and organizational capacity – a state form we have termed an ‘Exceptionalist State’.Resumen:En este artículo sostenemos que un entendimiento de la transformación de las capacidades y estructuras productivas de la economía ecuatoriana entre 2008 y 2014, puede darse desde el ángulo de la teoría del Estado. Específicamente, argumentamos que el fortalecimiento de la autoridad del Estado en Ecuador en el período analizado se ha dado a expensas del desarrollo de sus capacidades. Al posicionar al Estado en un lugar de ‘autoridad excepcional’, el gobierno central minó el desarrollo de redes formales en informales entre actores estatales y no-estatales, como la clase industrial. Así mismo, demostramos que las capacidades del Estado durante este período se han visto debilitadas por divisiones internas ligadas a eclécticos procesos de formación de liderazgos en la burocracia estatal. Estos procesos han resultado en la formación de un tipo de Estado híbrido que hemos denominado el

    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 Poco se sabe sobre cómo se crearon los ayuntamientos constitucionales en el caso de la Intendencia de Ciudad Real de Chiapas y cómo y cuándo comenzó a aplicarse la Constitución de Cádiz (1812 en este territorio. Para indagarlo hemos tomado en cuenta el papel jugado por los subdelegados como representantes de la autoridad monárquica a nivel local, y los diferentes actores de los pueblos en el momento mismo de la elección de los ayuntamientos, así como las estrategias y los conflictos surgidos entre ellos para designar a los miembros de dichas corporaciones. Luego de esta primera aproximación al tema nos percatamos de que, a diferencia de otros territorios, en el caso de la Intendencia de Chiapas el impacto del primer momento gaditano fue bastante limitado: únicamente se formó el ayuntamiento constitucional de Ciudad Real, que duró unos cuantos meses en operación. Hubo que esperar hasta 1821 para la creación de los ayuntamientos constitucionales. Una vez implantados estos, el papel de los subdelegados como representantes de la monarquía y garantes de la aplicación de la constitución gaditana fue muy desigual y conflictivo.

    Full Text Available O presente artigo discute a violência institucional em maternidades sob a ótica de profissionais de saúde, com base nos dados de uma pesquisa sobre o tema na cidade de São Paulo, Brasil. Para tanto, foram entrevistados 18 profissionais de saúde atuantes nas redes pública e privada, dentre médicos obstetras, enfermeiras e técnicas em enfermagem. Foi utilizado um roteiro semiestruturado com questões sobre a experiência profissional e o conceito de violência. A análise revelou o reconhecimento desses profissionais de práticas discriminatórias e desrespeitosas no cotidiano da assistência a mulheres gestantes, parturientes e puérperas. São exemplos citados dessas práticas o uso de jargões pejorativos como forma de humor, ameaças, reprimendas e negligência no manejo da dor. Essas práticas não são geralmente percebidas pelos profissionais como violentas, mas sim como um exercício de autoridade em um contexto considerado "difícil". Tal contexto revela a banalização da violência institucional que travestida de boa prática, porque seria para o bem da paciente, acaba invisibilizada no cotidiano da assistência.

    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.

Al ser la policía  uno de los grupos estratégicos más visibles y tradicionales de la estatalidad, se discute acerca de si ha tenido las competencias y capacidades necesarias para construir Estado desde abajo. Pero más importante aún, se ha examinado el perfil del policía que se requiere para gestionar las crisis, que ejerza adecuadamente su autoridad y cuente con la capacidad de tratamiento de otros eventos extraordinarios que pueden plantear serios desafíos a la gobernabilidad; por ejemplo, la probabilidad de conversión de grandes concentraciones urbanas en zonas caóticas, en las cuales la soberanía del Estado no sólo se erosionaría y sería retada, sino además estimularía la tendencia a la desintegración social y la desarticulación nacional. Para ello el prototipo policial tendría que estar dotado de una preparación basada en la versatilidad estratégica, la adopción de metodologías de trabajo anticipativo y el procesamiento inteligente del riesgo. Todo lo anterior como competencias indispensables para transitar de una mentalidad y formación profesional fundada en la realidad del mundo periférico a otra de connotación global.DOI: http://dx.doi.org/10.5377/rpsp.v3i1.1334

    This paper is intended to describe implementation of safety and security issues in the transport of radioactive material by the Nuclear Regulatory Authority (in Spanish Autoridad Regulatoria Nuclear, ARN), which is the Competent Authority of Argentina in Safety, Security and Safeguards of radioactive and nuclear material. There are depicted main regulatory activities dealing with the mentioned issues, and relevant milestones of national regulatory standards and guidance applied, that are based on requirements and guides from IAEA. Interfaces between Safety and Security sections are most of the times complementary but sometimes conflictive, therefore the resolution of such conflicts and goals achieved during their implementation are also commented; as well as future joint planned activities between both sections of ARN as a way to provide safety and security without compromising one or the other.

    Full Text Available Nesse artigo, tempos por finalidade discutir alguns aspectos referentes à afirmação da autoridade episcopal na Antiguidade Tardia, centrando nossa análise na atuação dos bispos como líderes que apresentam, entre os séculos III e V, uma preocupação recorrente com tudo aquilo que, em sua opinião, coloque em risco a integridade da Igreja, não apenas em termos de doutrina.mas também em termos disciplinares, o que os leva a investir em discursos e práticas visando a restabelecer a ordem na congregação. Nosso propósito é lançar alguma luz sobre a atuação dos bispos no cotidiano, destacando os desafios do cargo episcopal num momento de transição entre duas fases da Igreja, uma marcada pelo estranhamento com o poder imperial e outra na qual o cristianismo, embora reconhecido como religião oficial do Império, não deixa de suscitar pontos de divergência com as autoridades públicas. Para tanto, tomaremos como estudo de caso dois bispos que desempenharam, na Antiguidade Tardia, um importante papel no sentido de reforçar a autoridade episcopal: Cipriano, bispo de Cartago entre 249 e 258, e João Crisóstomo, bispo de Constantinopla entre 397 e 404.

    Full Text Available O presente trabalho tem como objetivo analisar a influência da autoridade monetária e da política monetária sobre a dinâmica comportamental dos bancos e, com isso, sobre a disponibilidade de crédito na economia, que, por sua vez, quando alterada, afeta a demanda agregada trazendo efeitos sobre emprego, produto e renda. Para tanto, destaca a influência da reputação da autoridade monetária e da transparência na implementação de suas políticas sobre o "estado de expectativas" dos bancos. O trabalho enfatiza a transmissão da política monetária para a economia pelos canais do crédito e das expectativas, realçando a influência da reputação e da transparência da autoridade monetária sobre o comportamento dos bancos.The following paper aims to examine the influence of monetary policy and its policies upon banks behavior and, consequently, upon credit disposal, which by the way, when modified affects aggregate demand bringing effects on employment, output and income.

Os três autores defendem uma visão hierárquica da educação e do ensino, considerando ser esse modelo institucional a melhor forma de encarar uma dinâmica interactiva inevitavelmente condicionada por um elevado potencial de conflito. Todos consideram que o sucesso da educação, em geral, e da educação escolar, em particular, depende, de modo decisivo, da eficácia da acção disciplinar, no quadro de uma liderança institucional que assegure a autoridade dos professores. É uma visão por muitos considerada tradicional e conservadora - os próprios autores tendem a considerá-la simplesmente realista - que desafia várias correntes pedagógicas anti-hierárquicas, e que, claramente, se opõe aos pressupostos e lógicas de acção que caracterizam o processo de personalização individualista, narcisista e hedonista da actual sociedade (pós moderna.Este artículo presenta, de forma resumida, la visión sociológica de tres autores clásicos - Émile Durkheim, Willard Waller e Philip Jackson -sobre la relación entre profesores y alumnos en el ámbito de la relación educativa y pedagógica.

    Full Text Available A Reforma em território alemão possui duas figuras, por vezes próximas entre si, por vezes muito distantes: Lutero e Tomás Müntzer. À medida que foi se envolvendo na vida de seus fiéis, Müntzer foi tomando caminhos próprios, discordando de Lutero que este tomava a "Palavra, em sua realidade objetiva, como constitutiva da Igreja, e afirmando que os verdadeiros fiéis são os que possuem a experiência subjetiva do "Espírito". Também contra Lutero, que defende a resistência à autoridade, mas em questões seculares aceita a tirania, Müntzer, que vê a fé fortemente inserida no social, defende a revolução armada contra os príncipes. Müntzer não nega a graça, mas esta possui papel secundário em seu pensamento, enquanto, para Lutero, ela se coloca no centro de suas preocupações teológicas

    Full Text Available En el Critón de Platón se instala un interesante argumento utilitarista para justificar la obligación política de los ciudadanos. El argumento sostiene que la violación de las leyes lleva a la destrucción de cualquier sistema jurídico y acarrea resultados perjudiciales para los miembros de la comunidad (50a6-50c. En este trabajo realizaremos un análisis crítico del argumento bajo los postulados de tres corrientes utilitaristas: el utilitarismo de acto, la generalización utilitarista y el utilitarismo de regla. Veremos cómo esta clase de argumentación presenta algunos inconvenientes a la hora de justificar la obediencia al derecho. Una vez realizado este estudio se propondrá otra interpretación complementaria sobre el significado del pasaje, en la que se destacará su costado retórico forense y la idea de la autoridad del derecho.

Para ello se realizó una revisión de la literatura de los últimos seis años en las bases de datos Science Direct, Ebsco, Redalyc y Scopus, y se encontró que si bien en el desarrollo de las conductas criminales convergen diversos elementos, los estilos de crianza, autoritarios, negligentes o demasiado permisivos, son uno de los factores explicativos de tipo ambiental más importantes del surgimiento de este tipo de conductas. Al finalizar se discuten las implicaciones de estos resultados en la construcción de programas de intervención y rehabilitación.

    Full Text Available El fortalecimiento de la capacidad rectora de las autoridades sanitarias, ahora y en futuras décadas, es asunto de relieve en el contexto de la reforma sectorial. Implica, entre otras cosas, replantear el lugar que ocupa la salud en el contexto de las principales tendencias sociales y económicas observables en el mundo en los albores del nuevo siglo, constituidas fundamentalmente por la redefinición del modelo de desarrollo, la creciente participación en el quehacer sanitario de entidades ajenas al Estado, la transición hacia una democracia participativa en diversos países, la modificación del concepto de lo "público" y lo "privado" y la globalización de la economía. En este nuevo panorama, se impone la necesidad de que el sector sanitario asuma una función distinta: coordinar la movilización de los recursos nacionales, a escala multisectorial, con miras a mejorar la equidad y el bienestar social y focalizar los escasos recursos que existen en los grupos sociales más desprotegidos. La liberalización de la producción y de la distribución de los bienes y servicios de salud, así como la dinámica de mercado que se observa cada vez más en el ámbito de estos servicios y la creciente autonomía de los sistemas de aseguramiento, constituyen nuevos retos para el ejercicio de la autoridad en materia de salud. Adicionalmente, la formación de bloques económicos regionales y el enorme peso ejercido por las grandes compañías multinacionales, con su control del mercado de medicamentos, instrumentos y tecnologías médicas, obligan al sector de la salud a buscar maneras de armonizar la legislación en el ámbito sanitario con las negociaciones de carácter internacional. Y todas estas exigencias superan, al parecer de no pocos expertos, la capacidad de los ministerios de salud de los países latinoamericanos para responder con la debida eficacia, en vista de las limitaciones impuestas en la actualidad por la organización, poder pol

    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. Este artículo no pierde de vista cómo se conjugan clivajes sociales diferentes en la dinámica de las relaciones de poder. Los datos analizados han sido construidos con trabajo de campo etnográfico en comisarías de la Policía de la Provincia de Buenos Aires.   Abstract   To think about the ways that women police officers from the Buenos Aires police force exercise authority leads to a reflection of the association between personal qualities and the relationships and institutionalized power taking place in workplaces.

This extra love is experienced sometimes as a duty and others as a strategy to capitalize job skills.

Para dar cuenta de por qué la desobediencia civil es moralmente justificable, primero se describen algunos rasgos esenciales de la desobediencia civil. Después se explica la manera en la que tensión entre el poder civil y el poder del individuo –tensión que se asume como la fuente de la desobediencia civil–, bajo la consideración de algunos pasajes de la Fundamentación metafísica de las costumbres, resulta sólo aparente. Una vez disuelta la tensión se defiende que las fuentes normativas individuales y sociales no sólo no se contraponen, sino que su complementariedad es necesaria para justificar la desobediencia civil. Aunque suene paradójico: sólo se puede abrir espacio a la desobediencia a partir de resaltar la importancia de la obediencia y de la ley.

    Full text: This paper points out a summary of the relevant aspects related to the transport of radioactive material in Argentina treated only from a regulatory focussing, it is to say from the point of view of its competent authority of application the Nuclear Regulatory Authority (in Spanish, the Autoridad Regulatoria Nuclear, ARN). Firstly, it is introduced the legal and regulatory framework applicable to the transport of radioactive material and the corresponding authorities involved (ARN, Secretary of Transport, and the Argentine Air Force, Naval Prefecture and Navy). Then, it is presented a schedule of the main characteristics of the shipments of radioactive material used in both the nuclear cycle and in medicine, industry and research, and an average of the shipments annually transported in Argentina. Further on the paper briefly analyses the ARN sources and the way in which it performs the compliance assurance with the in-force transport regulations in the country. Particularly, it is explained certain main tools used by the compliance system, as for example, transport notice, data base, licensing of certain design packages, shipments and materials, inspection and audits, and fees and sanctions regimes. On the other hand, it is mentioned the Argentine experience in the development, licensing, manufacture and use of domestic designs of Type B(U) packages and special form radioactive material (cobalt 60 and iridium 192 sealed sources). Moreover, it is concisely described test facilities available in the country necessary to perform the mentioned designs. Finally, the paper shortly describes the ARN main transport activities exclusively concerning the relationship with other national organisations (Federal Police, Gendarmerie, Naval Prefecture and Argentine Institute of Material Rationalisation, in Spanish Instituto Argentino de Racionalizacion de Materiales - IRAM) and with regional and inter regional organisations (South American Common Market, in Spanish

    The objective of this paper is to describe the main characteristics of the Nuclear Regulatory Authority (Autoridad Regulatoria Nuclear - ARN) management system applied to the transport of radioactive material, in Argentina. In the frame of ARN's quality policy, 'Protection against ionizing radiation on transport of radioactive materials' was selected as one of the regulatory processes, named TMR from now on. ARN's management system is integrally based on ISO 9000 system addressed to help organizations in designing and implementing their quality management systems. TMR process was split into five sub processes in order to facilitate the implementation of the system. Such sub processes were defined taking into account of the main functions developed by ARN in the branch of safe transport of radioactive materials. For each of this processes were specified their objectives, inputs, activities and outputs, clients and stakeholders, responsibilities, supporting documents, control of documents and records, control of non-conformances, monitoring and measurements, audits, feedback and improvement. Supporting documents for sub processes were issued, validated, reviewed and improved as an essential point to achieve continuous improving. Simultaneously, some indexes were defined to monitor and measures sub processes as a way to show objective evidence of conformity with objectives. Finally, as conclusions of this paper, they will be showed the main obstacles and troubleshooting found in the design and implementation of management system as well as their solutions and state of advance.

    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)

    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. Nineteen 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.

    2007-01-01

    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 Boskovic Inst. (RBI), Croatia, Jozef Stefan Inst. (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: 7 LiF (TLD-700), CaF 2 :Mn and Al2 O3 :Mg,Y - all from RBI; CaF 2 :Mn from JSI and 7 LiF (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. (authors)

    Full Text Available This piece of work intends to show the impact produced by the «porteña» politics among the Indians, who we have already mentioned, giving special emphasis to the attempts taken to eliminating or reducing indian theft. 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.

    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

    The committee concludes that the nature of the proliferation problem is such that even stopping nuclear power completely could not stop proliferation completely. Countries can acquire nuclear weapons by means independent of commercial nuclear power. It is reasonable to suppose if a country is strongly motivated to acquire nuclear weapons, it will have them by 2010, or soon thereafter, no matter how nuclear power is managed in the meantime. Unilateral and international diplomatic measures to reduce the motivations that lead to proliferation should be high on the foreign policy agenda of the United States. A mimimum antiproliferation prescription for the management of nuclear power is to try to raise the political barriers against proliferation through misuse of nuclear power by strengthening the Non-Proliferation Treaty, and to seek to raise the technological barriers by placing fuel-cycle operations involving weapons-usable material under international control. Any such measures should be considered tactics to slow the spread of nuclear weapons and thus earn time for the exercise of statesmanship. The committee concludes the following about technical factors that should be considered in formulating nuclear policy: (1) rate of growth of electricity use is a primary factor; (2) growth of conventional nuclear power will be limited by producibility of domestic uranium sources; (3) greater contribution of nuclear power beyond 400 GWe past the year 2000 can only be supported by advanced reactor systems; and (4) several different breeder reactors could serve in principle as candidates for an indefinitely sustainable source of energy

    This review discusses the methodology of nuclear forensics and illicit trafficking of nuclear materials. Nuclear forensics is relatively new scientific branch whose aim it is to read out material inherent from nuclear material. Nuclear forensics investigations have to be considered as part of a comprehensive set of measures for detection,interception, categorization and characterization of illicitly trafficking nuclear material. Prevention, detection and response are the main elements in combating illicit trafficking. Forensics is a key element in the response process. Forensic science is defined as the application of a broad spectrum of sciences to answer questions of interest to the legal system. Besides, in this study we will explain age determination of nuclear materials.

    Nuclear fuel is a material that can be consumed to derive nuclear energy, by analogy to chemical fuel that is burned for energy. Nuclear fuels are the most dense sources of energy available. Nuclear fuel in a nuclear fuel cycle can refer to the fuel itself, or to physical objects (for example bundles composed of fuel rods) composed of the fuel material, mixed with structural, neutron moderating, or neutron reflecting materials. Long-lived radioactive waste from the back end of the fuel cycle is especially relevant when designing a complete waste management plan for SNF. When looking at long-term radioactive decay, the actinides in the SNF have a significant influence due to their characteristically long half-lives. Depending on what a nuclear reactor is fueled with, the actinide composition in the SNF will be different. The following paper will also include the uses. advancements, advantages, disadvantages, various processes and behavior of nuclear fuels

    Nuclear lamins are intermediate filament proteins that represent important structural components of metazoan nuclear envelopes (NEs). By combining proteomics and superresolution microscopy, we recently reported that both A- and B-type nuclear lamins form spatially distinct filament networks at the nuclear periphery of mouse fibroblasts. In particular, A-type lamins exhibit differential association with nuclear pore complexes (NPCs). Our studies reveal that the nuclear lamina network in mammalian somatic cells is less ordered and more complex than that of amphibian oocytes, the only other system in which the lamina has been visualized at high resolution. In addition, the NPC component Tpr likely links NPCs to the A-type lamin network, an association that appears to be regulated by C-terminal modification of various A-type lamin isoforms. Many questions remain, however, concerning the structure and assembly of lamin filaments, as well as with their mode of association with other nuclear components such as peripheral chromatin.

    1987-01-01

    This book raises pointed questions about nuclear saber rattling. More than a dozen cases since the bombing of Hiroshima and Magasaki in which some sort of nuclear threat was used as a sparring technique in tense confrontations are cited. Each incident is described and analyzed. Two theories offered to explain America's use of nuclear threats, the balance of interest theory and the balance of power theory, are contrasted throughout the book. This book helps to fill the gap in the understanding of nuclear weapons and their uses, while pointing out that nuclear bravado could lead to an unintended unleashing of these weapons

    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

    Written from the basis of neutrality, neither for nor against nuclear power this book considers whether there are special features of nuclear power which mean that its development should be either promoted or restrained by the State. The author makes it dear that there are no easy answers to the questions raised by the intervention of nuclear power but calls for openness in the nuclear decision making process. First, the need for energy is considered; most people agree that energy is the power to progress. Then the historicalzed background to the current position of nuclear power is given. Further chapters consider the fuel cycle, environmental impacts including carbon dioxide emission and the greenhouse effect, the costs, safety and risks and waste disposal. No conclusion either for or against nuclear power is made. The various shades of opinion are outlined and the arguments presented so that readers can come to their own conclusions. (UK)

    The Autoridad Regulataria Nuclear (ARN) and the United States Department of Energy (DOE) are cooperating on the development of a Remote Monitoring System for nuclear nonproliferation efforts. A Remote Monitoring System for spent fuel transfer will be installed at the Argentina Nuclear Power Station in Embalse, Argentina. The system has been designed by Sandia National Laboratories (SNL), with Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (ORNL) providing gamma and neutron sensors. This project will test and evaluate the fundamental design and implementation of the Remote Monitoring System in its application to regional and international safeguards efficiency. This paper provides a description of the monitoring system and its functions. The Remote Monitoring System consists of gamma and neutron radiation sensors, RF systems, and video systems integrated into a coherent functioning whole. All sensor data communicate over an Echelon LonWorks Network to a single data logger. The Neumann DCM 14 video module is integrated into the Remote Monitoring System. All sensor and image data are stored on a Data Acquisition System (DAS) and archived and reviewed on a Data and Image Review Station (DIRS). Conventional phone lines are used as the telecommunications link to transmit on-site collected data and images to remote locations. The data and images are authenticated before transmission. Data review stations will be installed at ARN in Buenos Aires, Argentina, ABACC in Rio De Janeiro, IAEA Headquarters in Vienna, and Sandia National Laboratories in Albuquerque, New Mexico. 2 refs., 2 figs

Then exposes the complex relation between Hobbes and democracy and his notion of political representation. After reconstructing some of Hobbes' basic objections to classical political thought, the text tries to show that the English philosopher works, with respect to Aristotle, with a relatively unaltered concept of nature. The major objective of the paper is to configure the State as a genuine product of the intellectual performance of the English political theoretician.

    The D-T fusion cross-section is calculated using quantum mechanics with the model of square nuclear potential well and Coulomb potential barrier. The agreement between ENDF data and the theoretically calculated results is well in the range of 0.2-280 keV. It shows that the application of Breit-Wigner formula is not suitable for the case of the light nuclei fusion reaction. When this model is applied to the nuclear reaction between the charged particles confined in a lattice, it explains the 'abnormal phenomena'. It implies a prospect of nuclear fusion energy without strong nuclear radiations

    1987-01-01

    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

    Nuclear measurements play a fundamental role in the development of nuclear technology and the assurance of its peaceful use. They are also required in many non-power nuclear applications such as in nuclear medicine, agriculture, environmental protection, etc. This presentation will show examples of most recent advances in measurement methodology or technology in the areas described below. The Generation IV International Forum has selected six innovative reactor systems as candidates for a next generation of sustainable, economic and safe nuclear energy systems. The choice of the best options relies heavily on the availability of accurate nuclear data that can only be obtained, in an international effort, using highly specialised facilities. Significant efforts are being directed towards the partitioning and transmutation of highly active nuclear waste. Different concepts involving fast reactors or accelerator-driven systems are being studied in view of their transmutation capabilities. State of the art equipment has been developed to assess basic properties of nuclear fuel at very high burn-up; some fine examples of this work will be shown. Physical and chemical methods play a crucial role in the detection and identification of radioisotopes used in various stages of the nuclear fuel cycle. Radiation measurement techniques are used, for example, to monitor the quantities of uranium, plutonium and other actinide elements in fuel enrichment and reprocessing facilities. Another field of application of physical and chemical methods is the characterisation of nuclear material seized from illicit trafficking. Seized material has to be analysed in order to obtain clues on its origin and intended use and to prevent diversion of nuclear material from the same source in the future. A recent highlight in basic physics relates to nuclear fission and transmutation with high intensity lasers. Ultra-fast high intensity lasers can produce high energy (tens of MeV) photons through

Two scientists are regarded as pioneers in this field, i.e. John Lawrence who in 1938 used 32 P to treat chronic myeloid leukaemia and George Hevessy who used 32 P 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

    Increasing threat by terrorists for a possible nuclear attack is particularly alarming in recent years. The likelihood of such an event is highly uncertain but cannot be ruled out. The consequence of such an event would be highly disastrous and the implications could be far-reaching both socially and politically. It is feared that significant amount of nuclear weapons materials may be kept under poor security. Therefore, there is a greater demand with utmost priority to curb nuclear terrorism by adapting proper security measures. One of the most important measures is to stop illicit trafficking of nuclear materials which are the source of building nuclear explosive devices. According to the IAEA illicit trafficking database (ITDB) report, a total number of 252 incidents were reported in 2006, of which 150 occurred in 2006 and the remaining 102 had taken place prior to that year, mainly in 2005

    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.

    The terms and reactions to President Carter's nuclear policy, culminating in the 1978 Nuclear Non-Proliferation Act, are reviewed and analyzed. The new law increases restrictions on nuclear exports, encourages continued use of light water reactors in preference to plutonium-fueled reactors, and emphasizes technical solutions to proliferation problems. Critics of the law point out that it will hurt U.S. trade unfairly, that other countries do not have as many fuel options as the U.S. has, and that nuclear sales have as many political and economic as technical solutions. Compromise areas include new international safety guidelines, the possibility of an international nuclear fuel bank, and a willingness to consider each case on its merits. 21 references

    The United Kingdom government announced in May 1995 plans to privatize the country's two nuclear generating companies, Nuclear Electric and Scottish Nuclear. Under the plan, the two companies will become operating divisions of a unified holding company, to be called British Electric, with headquarters in Scotland. Britain's nuclear plants were left out of the initial privatization in 1989 because the government believed the financial community would be unwilling to accept the open-ended liability of decommissioning the original nine stations based on the Magnox gas-cooled reactor. Six years later, the government has found a way around this by retaining these power stations in state ownership, leaving the new nuclear company with the eight Advanced Gas-cooled Reactor (AGR) stations and the recently completed Sizewell B PWR stations. The operating Magnox stations are to be transferred to BNFL, which operates two Magnox stations of their own at Calder Hall and Chapelcross

    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

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

  3. Nuclear Hostages

    International Nuclear Information System (INIS)

    Cooper, C.L.

    1978-01-01

    The global spread of nuclear reactors for the production of energy seems inevitable. Nuclear power plants will be supplied--if not by the United States, then by one of several other exporters. But other aspects of this development are less certain. One is the relationship between proliferation of nuclear energy plants and that of nuclear weapons. Another is the actual constraint that such vulnerable potential targets as nuclear power plants would have on would-be aggressors. In the last analysis, this would depend on the rationality of a nation's leadership. What can be said for the concept of nuclear power plants as potential hostages is that by installing a reactor on its territory, a country increases its vulnerability to grave, possibly unacceptable damage in the event of war. As a result, that nation's leaders might be inclined to raise the threshold of their sensitivity to provocation by neighbors and to restrain their own inclinations toward aggression. Admittedly this is a frail substitute for robust international agreements, but in the present order of things it is not a trivial consideration. Many incidents once regarded by the great powers as easi belli have more recently been either resolved by diplomacy or ignored altogether. The idea must not be pressed too far. The export of a nuclear power plant to a Third World country cannot be advocated simply as a means to constrain its own military adventurism. Aside from the promise of a vast increase in energy supply for developing nations, nuclear powered generating stations could actually improve relations among countries. The risk of widespread radioactive contamination by nuclear power plants hit by even conventional bombs could introduce a positive new element into the military calculations of powers outside the NATO-Warsaw Pact arena. As they balance military and diplomatic solutions to local conflicts, moderation rather than bellicosity might become the better part of valor

    Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials to examine organ function and structure. Nuclear medicine is older than CT, ultrasound and MRI. It was first used in patients over 60-70 years ago. Today it is an established medical specialty and offers procedures that are essential in many medical specialities like nephrology, pediatrics, cardiology, psychiatry, endocrinology and oncology. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). This combination is called a radiopharmaceutical. There are many radiopharmaceuticals like DTPA, DMSA, HIDA, MIBI and MDP available to study different parts of the body like kidneys, heart and bones etc. Nuclear medicine uses radiation coming from inside a patient's body where as conventional radiology exposes patients to radiation from outside the body. Thus nuclear imaging study is a physiological imaging, whereas diagnostic radiology is anatomical imaging. It combines many different disciplines like chemistry, physics mathematics, computer technology, and medicine. It helps in diagnosis and to treat abnormalities very early in the progression of a disease. The information provides a quick and accurate diagnosis of wide range of conditions and diseases in a person of any age. These tests are painless and most scans expose patients to only minimal and safe amounts of radiation. The amount of radiation received from a nuclear medicine procedure is comparable to, or often many times less than, that of a diagnostic X-ray. Nuclear medicine provides an effective means of examining whether some tissues/organs are functioning properly. Therapy using nuclear medicine in an effective, safe and relatively inexpensive way of controlling and in some cases eliminating, conditions such as overactive thyroid, thyroid cancer and arthritis. Nuclear medicine imaging is unique because it provides doctors with

    Since the end of the East-West confronting, the nuclear weapon issue has been focused in an international debate with obvious repercussions in Europe, because it is the European continent which indicated first the significance of nuclear deterrence. This debate refers first upon the past, as the German unification allowed capturing numerous documents of Warsaw treaty which revealed the intentions and the plans of Soviet Union during the cold war, and secondly concerns the future, since the role of nuclear weapons must be re-thought in a new context. This is the subject of this book, which refers also to the problem of the nuclear proliferation in the world and evolution of different countries in a political and regional context. The extension of the non-proliferation treaty for an undefined duration, in May 1995, is a incontestable victory because this treaty rules the renouncement to nuclear weapons of 185 countries. However, it does not solve most sensible problems like the Iraq case, for which a specific inspection regime has been instituted, or the case of Iran, which is suspected to acquire the bomb, although no clear evidence has been provided up to now. This is also the case of Israel, India and Pakistan which allege plainly their willingness of keeping open, from security reasons, their nuclear option. The content is displayed in five chapters: 1. Introduction; 2. The role of the nuclear weapons after the cold war; 3. The nuclear proliferation at crossroads; 4. Undefined extension of the NPT, a striking but fragile victory; 5. Conclusions. An appendix containing the text of the Nuclear Weapon Non-Proliferation Treaty and a chronology are added

    During january and february 2003, a unique event concerning nuclear transport was reported and rated 1 on the INES scale. This event concerns the absence of a maintenance operation on a shipping cask. This shipping cask was used for several years for nuclear transport inside La-hague site before being re-assigned to transport on public thoroughfare. The re-assignment of the cask should have been preceded and conditioned by a maintenance operation whose purpose is to check the efficiency of its radiation shield. During this period 2 on-site inspections concerning the transport of nuclear materials were performed. (A.C.)

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

    Full Text Available O tema deste artigo é a compreensão política propagada entre as décadas de 1060 e 1120 por eminentes eclesiásticos engajados na legitimação e no exercício do poder papal. 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.

    Full Text Available Este artigo tem como objetivo narrar uma experiência concreta com aulas participativas. 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.

    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

    The first volume of the Annual Report for 1989/90 gives an overview of the Nuclear Structure Facility at Daresbury, its development and a selection of highlights of the year's programme. This volume is complementary, presenting brief specialist reports, submitted by the users, describing the progress and results of each individual proposal. The contents reflect the extremely successful year due in good measure to the performance of the tandem accelerator which provided a record number of hours with ''beam on target''. Reports are grouped in four sections: research into nuclear structure with contributions ordered in increasing Z numbers of the nuclei studied; investigations of nuclear reaction mechanisms; nuclear theory; accelerator operations and development plus experimental instrumentation and techniques. The appendix forms a concise summary of the work at the facility for the year. (author)

    This chapter present a brief overview of the current situation of siting radioactive wastes. This is followed by an overview of various psychological approaches attempting to analyse public reactions to nuclear facilities. It will be argued that public reactions to nuclear waste factilities must be seen in the context of more general attitudes toward nuclear energy. The latter are not only based upon perceptions of the health and environmental risks but are built on values, and sets of attributes which need not be similar to the representations o the experts and policy-makers. The issue of siting nuclear waste facilities is also embedded in a wider moral and political domain. This is illustrated by the importance of equity issues in siting radioactive wastes. In the last section, the implications of the present line of argument for risk communication and public participation in decisions about siting radioactive wastes will be briefly discussed.

    Astronomy deals with the position and observation of the objects in our Universe, from planets to galaxies. It is the oldest of the sciences. Astrophysics is the study of the physical properties of these objects. It dates from the start of the 20. century. Nuclear astrophysics is the marriage of nuclear physics, a laboratory science concerned with the infinitely small, and astrophysics, the science of what is far away and infinitely large. Its aim is to explain the origin, evolution and abundance of the elements in the Universe. It was born in 1938 with the work of Hans Bethe, an American physicist who won the Nobel Prize for physics in 1967, on the nuclear reactions that can occur at the center of stars. It explains where the incredible energy of the stars and the Sun comes from and enables us to understand how they are born, live and die. The matter all around us and from which we are made, is made up of ninety-two chemical elements that can be found in every corner of the Universe. Nuclear astrophysics explains the origin of these chemical elements by nucleosynthesis, which is the synthesis of atomic nuclei in different astrophysical environments such as stars. Nuclear astrophysics provides answers to fundamental questions: - Our Sun and the stars in general shine because nuclear reactions are taking place within them. - The stars follow a sequence of nuclear reaction cycles. Nucleosynthesis in the stars enables us to explain the origin and abundance of elements essential to life, such as carbon, oxygen, nitrogen and iron. - Star explosions, in the form of supernovae, disperse the nuclei formed by nucleosynthesis into space and explain the formation of the heaviest chemical elements such as gold, platinum and lead. Nuclear astrophysics is still a growing area of science. (authors)

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. Given the highly varied and complex aspects, we pick here some specific nuclear

    The Program on Nuclear Safety comprehends Radioprotection, Radioactive Waste Management and Nuclear Material Control. These activities are developed at the Nuclear Safety Directory. The Radioactive Waste Management Department (GRR) was formally created in 1983, to promote research and development, teaching and service activities in the field of radioactive waste. Its mission is to develop and employ technologies to manage safely the radioactive wastes generated at IPEN and at its customer’s facilities all over the country, in order to protect the health and the environment of today's and future generations. The Radioprotection Service (GRP) aims primarily to establish requirements for the protection of people, as workers, contractors, students, members of the general public and the environment from harmful effects of ionizing radiation. Furthermore, it also aims to establish the primary criteria for the safety of radiation sources at IPEN and planning and preparing for response to nuclear and radiological emergencies. The procedures about the management and the control of exposures to ionizing radiation are in compliance with national standards and international recommendations. Research related to the main activities is also performed. The Nuclear Material Control has been performed by the Safeguard Service team, which manages the accountability and the control of nuclear material at IPEN facilities and provides information related to these activities to ABACC and IAEA.

    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.

    This set of questions is based on an inquiry from the years 1987 to 1989. About 250 people af all age groups - primarily, however, young people between 16 and 25 years of age - were asked to state the questions they considered particularly important on the subject of nuclear energy. The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    In recent days, energy security is becoming a major global concern and it has been recognized that a major reduction in greenhouse-gas emissions is required to combat climate change. Considerable expansion and new introduction of nuclear power generation are currently being planned and considered for the further in various parts of the world. Nuclear technologies of the latest 10 years in Japan were reviewed with their characteristics, advancement and future perspective. Steady efforts have been made to construct new nuclear power stations with computer-aided engineering system and modular and prefabricated structures, extend the interval of periodic inspections under the new inspection system that should improve both safety and reliability, implement advanced measures against aging and develop the next-generation light water reactors including a medium small reactor. Export of nuclear power plants has been promoted with international business alliance or cooperation. Activities to close nuclear fuel cycle to ensure sustainable nuclear energy utilization have been promoted. Decommissioning technologies for Tokai power station have been developed and accumulated know-how will be utilized in light water reactors. (T. Tanaka)

    In 1979 the accident at Three Mile Island brought nuclear power to the forefront of national attention. Over the last five years there have been no new orders for nuclear plants, construction costs and lead times have increased drastically, and numerous plants have been cancelled. In the coming years many new plants will come on line, and the first round of nuclear plant retirements will begin. Thus, the new set of issues faced by utilities are whether to complete plants currently under construction, how to recover the cost of abandoned plants, how to handle the potential rate shock of bringing costly plants into rate base, and how to accomplish decommissioning and retirement of nuclear plants. This paper presents and analyzes these issues. First, the history of the nuclear electric generation industry is reviewed. Next a case study illustrating the cost momentum built into nuclear power plant construction is presented. The issues involved in plant cancellation are discussed. Finally, a case study involving rate phase-in strategies is analyzed. 1 reference, 7 figures

    The Koeberg nuclear power station, planned to come on stream in 1984, is expected to save South Africa some six million t/annum of coal, and to contribute some 10 per cent of the country's electricity requirements. The use of nuclear energy will provide for growing national energy needs, and reduce high coal transport costs for power generation at the coast. In the long term, however, it gives rise to the controversial question of nuclear waste storage. The Atomic Energy Corporation of South Africa Ltd (AEC) recently announced the purchase of a site in Namaqualand (NW Cape) for the storage of low-level radioactive waste. The Nuclear Development Corporation of South Africa (Pty) Ltd, (NUCOR) will develop and operate the site. The South African Mining and Engineering Journal interviewed Dr P.D. Toens, manager of the Geology Department and Mr P.E. Moore, project engineer, on the subject of nuclear waste, the reasons behind Nucor's choice of site and the storage method

    Levenson, M.

    1989-01-01

    The title of our session, Nuclear Risk Versus Other Power Options, is provocative. It is also a title with different meanings to different people. To the utility chief executive officer, nuclear power is a high-risk financial undertaking because of political and economic barriers to cost recovery. To the utility dispatcher, it is a high-risk future power source since plant completion and start-up dates can be delayed for very long times due to uncertain legal and political issues. To the environmentalist, concerned about global effects such as greenhouse and acid rain, nuclear power is a relatively low risk energy source. To the financial people, nuclear power is a cash cow turned sour because of uncertainties as to what new plants will cost and whether they will even be allowed to operate. The statistics on risk are known and the results of probability risk assessment calculations of risks are known. The challenge is not to make nuclear power safer, it is already one of the safest, if not the safest, source of power currently available. The challenge is to find a way to communicate this to the public

  7. Nuclear recession

    Speth, G.

    1978-01-01

    The private sector's growing doubts about nuclear power plants, as reflected in the decline in new orders and the number of rescinded orders, will result in an estimated total of under 300 nuclear power plants by the year 2000 rather than the 1200 to 1500 that were projected several years ago. The decline is a result of construction and equipment costs and a lower operating efficiency than anticipated. The growth of electricity demand also declined after 1974 and, although it is increasing again, there are concerns about future growth rates. Besides its noncompetitive position relative to coal, nuclear plant construction suffers from restrictive policies based on the uncertainties of safety, security, waste disposal, and proliferation. Unless these problems can be resolved, many consider nuclear power to be an impractical option as an energy source. The Council on Environmental Quality supports policies that will permit further nuclear or coal development only after a clear demonstration of technical and institutional capacity to handle these problems. A commitment to solar technology is urged

    Nuclear fusion can be relied on to solve the global energy crisis if the process of limiting the heat produced by the fusion reaction (Plasma) is successful. Currently scientists are progressively working on this aspect whereas there are two methods to limit the heat produced by fusion reaction, the two methods are auto-restriction using laser beam and magnetic restriction through the use of magnetic fields and research is carried out to improve these two methods. It is expected that at the end of this century the nuclear fusion energy will play a vital role in overcoming the global energy crisis and for these reasons, acquiring energy through the use of nuclear fusion reactors is one of the most urge nt demands of all mankind at this time. The conclusion given is that the source of fuel for energy production is readily available and inexpensive ( hydrogen atoms) and whole process is free of risks and hazards, especially to general health and the environment . Nuclear fusion importance lies in the fact that energy produced by the process is estimated to be about four to five times the energy produced by nuclear fission. (author)

    Full text: This paper points out a summary of the relevant aspects related to the transport of radioactive material in Argentina treated only from a regulatory focussing, it is to say from the point of view of its competent authority of application the Nuclear Regulatory Authority (in Spanish, the Autoridad Regulatoria Nuclear, ARN). Firstly, it is introduced the legal and regulatory framework applicable to the transport of radioactive material and the corresponding authorities involved (ARN, Secretary of Transport, and the Argentine Air Force, Naval Prefecture and Navy). Then, it is presented a schedule of the main characteristics of the shipments of radioactive material used in both the nuclear cycle and in medicine, industry and research, and an average of the shipments annually transported in Argentina. Further on the paper briefly analyses the ARN sources and the way in which it performs the compliance assurance with the in-force transport regulations in the country. Particularly, it is explained certain main tools used by the compliance system, as for example, transport notice, data base, licensing of certain design packages, shipments and materials, inspection and audits, and fees and sanctions regimes. On the other hand, it is mentioned the Argentine experience in the development, licensing, manufacture and use of domestic designs of Type B(U) packages and special form radioactive material (cobalt 60 and iridium 192 sealed sources). Moreover, it is concisely described test facilities available in the country necessary to perform the mentioned designs. Finally, the paper shortly describes the ARN main transport activities exclusively concerning the relationship with other national organisations (Federal Police, Gendarmerie, Naval Prefecture and Argentine Institute of Material Rationalisation, in Spanish Instituto Argentino de Racionalizacion de Materiales - IRAM) and with regional and inter regional organisations (South American Common Market, in Spanish

  10. Nuclear scales

    International Nuclear Information System (INIS)

    Friar, J.L.

    1998-01-01

    Nuclear scales are discussed from the nuclear physics viewpoint. 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 π-γ force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted

    Holinde, K.

    1990-01-01

    In this paper the present status of the meson theory of nuclear forces is reviewed. After some introductory remarks about the relevance of the meson exchange concept in the era of QCD and the empirical features of the NN interaction, the exciting history of nuclear forces is briefly outlined. In the main part, the author gives the basic physical ideas and sketch the derivation of the one-boson-exchange model of the nuclear force, in the Feynman approach. Secondly we describe, in a qualitative way, various necessary extensions, leading to the Bonn model of the N interaction. Finally, points to some interesting pen questions connected with the extended quark structure of the hadrons, which are topics of current research activity

    2010-01-01

    The International Year of Astronomy 2009 (IYA2009) was declared by the 62nd General Assembly of the United Nations and was also endorsed by UNESCO. Investigations in the realms of particle and nuclear physicsmake a large contribution in the development of our ideas of the properties of the Universe. The present article discusses some problems of the evolution of the Universe, nucleosyntheses, and cosmochronology from the point of view of nuclear and particle physics. Processes occurring in the Universe are compared with the mechanisms of the production and decay of nuclei, as well as with the mechanisms of their interaction at high energies. Examples that demonstrate the potential of nuclearphysics methods for studying cosmic objects and the properties of the Universe are given. The results that come from investigations into nuclear reactions induced by beams of radioactive nuclei and which make it possible to take a fresh look at the nucleosynthesis scenario in the range at light nuclei are presented.

  13. Nuclear scales

    Energy Technology Data Exchange (ETDEWEB)

    Friar, J.L.

    1998-12-01

    Nuclear scales are discussed from the nuclear physics viewpoint. 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 effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted.

    Then-President Gerald Ford outlines the potential benefits of nuclear power as opposed to the danger of proliferation. He points out that not all nations have the same interest or views toward nuclear energy; but also he says that if a choice must be made, nonproliferation objectives must take precedence over economic and energy benefits. It is pointed out that the management of nuclear energy can be only partial and temporary by technical measures, and that full management can result only if nations realistically face the task prepared to forego preconceived short-term advantages in favor of long-term gains. Coordination of the policies of all nations toward the common goal of nonproliferation is predicted to lead to success

    1986-01-01

    Written by an arts graduate journalist this is intended for a non-technical general readership. It chronicles the history of the nuclear power industry in Britain from its beginnings, which were inextricably tied to the development of the atomic bomb, to the Sellafield investigation and Sizewell public inquiry. In particular the government decisions which have influenced the present structure and state of the industry are criticised. With important decisions about to be made the author questions the accountability of the nuclear industry and the government's ability to understand the complex technical aspects of the industry.

  19. Nuclear dilemma

    Energy Technology Data Exchange (ETDEWEB)

    Penn, J.

    Declaring nuclear preparedness 'immoral' helps to recreate the pacifism of 50 years ago. War itself is a dilemma, not the weapons with which it is waged. We must ask of the anti-war proposals: whom do they benefit. On the whole people concerned are ordinary citizens who are fearful of nuclear incineration. But marching with them is a spectrum of forces with other motivations and purposes. In a real life situation of international tension or crises, numbers of weapons in combination with their particular charateristics could mean the difference between peace and outbreak of war.

    1979-01-01

    The recent, terrifying threat of a major calamity at Pennsylvania's Three Mile Island power plant near Harrisburg reverberated across practically the whole of the civilised world. An almost incredible sequence of human and mechanical failures at this installation had stopped just short of disaster and had brought the unthinkable perilously close to happening. The accident had sprayed radioactive waste into the air and had led to the large scale evacuation of people from the endangered area, disrupted hundreds of thousands of lives and caused a crippling setback to the nuclear industry. In this article the author discusses the impact the Harrisburg incident has had on the nuclear industry

  1. Nuclear cardiology

    International Nuclear Information System (INIS)

    Bashore, T.M.; Shaffer, P.B.

    1985-01-01

    The birth of nuclear cardiology has generally been attributed to a 1927 experiment during which a radium salt was injected in one arm vein and the circulation time calculated by recording the arrival of the radioactivity in the opposite arm. This simple experiment lead to the radiocardiogram in the late 1940s that was used to measure left ventricular function and, later, cardiac output. This chapter provides a brief overview of nuclear cardiology. Methodology is presented when it is important for the understanding of test results. The use of these studies in the diagnosis and evaluation of patients with suspected cardiovascular disease is emphasized

    Nuclear medicine as a complex diagnostical method is used mainly to detect functional organic disorders, to locate disorders and for radioimmunologic assays (RIA) in vitro. In surgery, its indication range comprises the thyroid (in vivo and in vitro), liver and bile ducts, skeletal and joint diseases, disorders of the cerebro-spinal liquor system and the urologic disorders. In the early detection of tumors, the search for metastases and tumor after-care, scintiscanning and the tumor marcher method (CEA) can be of great practical advantage, but the value of myocardial sciritiscanning in cardiac respectively coronary disorders is restricted. The paper is also concerned with the radiation doses in nuclear medicine. (orig.) [de

  6. Nuclear energy and nuclear technology

    International Nuclear Information System (INIS)

    Luescher, E.

    1982-01-01

    This book originated in the training courses for teachers of grammar- and secondary schools in Dillingen (Bavaria). The aim of these courses is to become informed about the latest state in one field of physics. The lectures are well-known experts in the respective fields. In the latest study (1980) of the National Academy of Sciences the experts came to the conclusion that without further development nuclear power plants the utilization of too much coal would become necessary and involve irreversible environmental damage (see chapter 6). There are two important obstacles impeding the further extension of nuclear energy. The first problem to be solved is the processing and storage of radioactive waste. This is a more technical task and can be treated in a satisfactory way. The second obstacle is less easy to take as the population has to be convinced that a nuclear power plant can be operated with almost unbelievable safety (see chapter 5) and be shut down safely in the case of incidents. The most promising possibility of controlled nuclear fusion as energy source is still many decades- if feasible at all- away from being performed (see chapter. 7). In the Soviet Union 25% of the electric energy production shall be proceed from nuclear power plants by the year 1990. (orig./GL) [de

  7. Nuclear winter or nuclear fall?

    Science.gov (United States)

    Berger, André

    Climate is universal. If a major modern nuclear war (i.e., with a large number of small-yield weapons) were to happen, it is not even necessary to have a specific part of the world directly involved for there to be cause to worry about the consequences for its inhabitants and their future. Indeed, smoke from fires ignited by the nuclear explosions would be transported by winds all over the world, causing dark and cold. According to the first study, by Turco et al. [1983], air surface temperature over continental areas of the northern mid-latitudes (assumed to be the nuclear war theatre) would fall to winter levels even in summer (hence the term “nuclear winter”) and induce drastic climatic conditions for several months at least. The devastating effects of a nuclear war would thus last much longer than was assumed initially. Discussing to what extent these estimations of long-term impacts on climate are reliable is the purpose of this article.

    Nuclear reactions' marks a new development in the study of television as an agency of public policy debate. During the Eighties, nuclear energy became a major international issue. The disasters at Three-mile Island and Chernobyl created a global anxiety about its risks and a new sensitivity to it among politicians and journalists. This book is a case-study into documentary depictions of nuclear energy in television and video programmes and into the interpretations and responses of viewers drawn from many different occupational groupings. How are the complex and specialist arguments about benefit, risk and proof conveyed through the different conventions of commentary, interview and film sequence? What symbolic associations does the visual language of television bring to portrayals of the issue? And how do viewers make sense of various and conflicting accounts, connecting what they see and hear on the screen with their pre-existing knowledge, experience and 'civic' expectations. The authors examine some of the contrasting forms and themes which have been used by programme makers to explain and persuade, and then give a sustained analysis of the nature and sources of viewers' own accounts. 'Nuclear Reactions' inquires into the public meanings surrounding energy and the environment, spelling out in its conclusion some of the implications for future media treatments of this issue. It is also a key contribution to the international literature on 'television knowledge' and the processes of active viewing. (author)

  18. Nuclear waste

    International Nuclear Information System (INIS)

    1990-06-01

    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

    Full text: The objective of this paper is to describe the main characteristics and fundamentals of the Nuclear regulatory Authority's (Autoridad Regulatoria Nuclear, ARN) management system applied to the regulation of transport of radioactive material, in Argentina. In the frame of ARN's quality policy, 'Protection against ionizing radiation on transport of radioactive materials' was selected as one of the regulatory processes, named TRM process from now on. ARN's quality management system is integrally based on ISO 9000 system addressed to help organizations in designing and implementing their quality management systems. TRM process was split into five sub processes in order to facilitate the implementation of quality system. Such sub processes were defined taking account of the main functions developed by ARN in the branch of safe transport of radioactive materials and are listed below: 1) Development and updating of standards and regulatory guides; 2) Licensing of packages, special radioactive materials and consignments of radioactive materials; 3) Compliance assurance during the transport of radioactive materials, and 4) Training, advising and communications. For each of these sub processes were specified their objectives, inputs, activities and outputs, the clients and stakeholders, responsibilities, supporting documents, control of documents and records, control of non-conformances, monitoring and measurements, audits, feedback and improvement. It was decided to develop a quality plan to organize and manage activities to meet quality requirements, to optimize the use of limited resources of the organization and to be used as a basis for monitoring and assessing compliance with the requirements, both internal and external. Supporting documents for sub processes were issued, validated, reviewed and improved as an essential point to implement continuous improving. Simultaneously, some indexes were defined to monitor and measure the sub processes as a way to show

    Nuclear astrophysics, a fruitful combination of nuclear physics and astrophysics can be viewed as a special application of nuclear physics where the study of nuclei and their reactions are motivated by astrophysical problems. Nuclear astrophysics is also a good example for the state of the art interdisciplinary research. The origin of elements studied by geologists is explored by astrophysicists using nuclear reaction rates provided by the nuclear physics community. Due to the high interest in the field two recent Nuclear Physics Divisional Conferences of the European Physical Society were devoted to nuclear astrophysics and a new conference series entitled 'Nuclear Physics in Astrophysics' has been established. Selected problems of nuclear astrophysics will be presented emphasizing the interplay between nuclear physics and astrophysics. As an example the role of 14 N(p,r) 15 O reaction rate in the determination of the age of globular clusters will be discussed in details

According to these these the DKVG (German nuclear power plant insurance association) has 102 member insurance companies all registered in the Federal Republic of Germany. By using reinsurance capacities of the other pools at present property insurance amounts to 1.5 billion DM and liability insurance to 200 million DM. In 1991 the damage charges on account of DKV amounted to 3.1 (1990 : 4.3) million DM. From these 0.6 million DM are apportioned to payments and 2.5 million DM to reserves. One large damage would cost a maximum gross sum of 2.2 billion DM property and liability insurance; on account of DKVG 750 million DM. (orig./HSCH) [de

    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.

    Purpose: To improve the nuclear reactor availability by enabling to continuously exchange fuels in the natural-slightly enriched uranium region during operation. Constitution: A control rod is withdrawn to the midway of a highly enriched uranium region by means of control rod drives and the highly enriched uranium region is burnt to maintain the nuclear reactor always at a critical state. At the same time, fresh uranium-slightly enriched uranium is continuously supplied gravitationally from a fresh fuel reservoir through fuel reservoir to each of fuel pipes in the natural-slightly enriched uranium region. Then, spent fuels reduced with the reactivity by the burn up are successively taken out from the bottom of each of the fuel pipes through an exit duct and a solenoid valve to the inside of a spent fuel reservoir and the burn up in the natural-slightly enriched uranium region is conducted continuously.

    The Privacy Act of 1974 restricts both the type of information on private individuals that federal agencies may maintain in their records and the conditions under which such information may be disclosed. The Nuclear Regulatory Commission, which must approve DOE plans to build a nuclear waste repository at the Yucca Mountain site in Nevada, requires a quality assurance program to guarantee that studies of the site are done by qualified employees. Under such a program, the training and qualifications of DOE and contractor employees would be verified. This report reviews DOE's efforts to identify and resolve the implications of the Privacy Act for DOE's quality assurance program and how the delay in resolving Privacy Act issues may have affected preliminary work on the Yucca Mountain project

    The many diverse programmes of fundamental research and technical development at the Daresbury Nuclear Structure Facility (NSF) have continued at their usual hectic pace throughout the period 1988/89. An overview of the overall programme and of the Facility has been presented in the first volume of this report, along with an expanded discussion of some of the highlights of the year's work. This second volume presents the more technical and detailed reports on the progress and results of individuals proposals and hence will be of most interest to the more expert reader. The reports are grouped in terms of experimental studies aimed at probing the structure of individual nuclei or series of nuclei, studies devoted to probing the primary nuclear reaction mechanism itself, theoretical work and research devoted to the development of the accelerator, and experimental equipment/techniques. Overall, they provide a concise summary of the year's work at the NSF. (author)

    Close cooperation with the Ministry of Industry with representation from the UNESA Safeguards Group, has meant that, after almost two years of intense meetings and negotiations, Spain has a specific plant to plant agreement for the application of Safeguards under this new method. This is an agreement which aims to be a benchmark for all other EU countries, as the IAEA tends to apply a generic agreement that, in many cases, majority interferes in the nuclear power plants own processes.

  18. Nuclear terrorism

    Watson, C.

    2005-01-01

    This article is aimed at those professional scientists and engineers who believe that issues of international peace and security are too important to be left to the politicians. Nuclear Terrorism is a hostile act (or a threat of such an act) involving nuclear materials (fissile or radioactive) performed by a terrorist, a term which covers a wide range of individuals. What they all have in common is that, for some reason they have become motivated to hurt or destroy sections of society which they have come to regard as the enemy; their motivation varies enormously. They also vary enormously in the extent and nature of their technical/scientific education. There are 'PhD terrorists' and 'Peasant terrorists', and they differ greatly in the threat that they represent, and the steps which can appropriately be taken to counter it. The most serious threat comes from the potential ability of terrorists to steal or manufacture nuclear weapons of mass destruction (e.g. capable of causing thousands of deaths). Unless the underlying causes of terrorism can be quickly removed, we have a duty to mankind to make terrorist access to such weapons, and to the nuclear materials which are their essential ingredients, as difficult as possible. Improvements in the arrangements for denying unauthorised access to radioactive material should be made such that the protective measures made are proportionate to the number of Curies at risk and the likelihood of a terrorist initiative. The preventative measures, sadly, need to take account of the possibility that the terrorist will use lethal force to access the material. (author)

    Except for dedicated devices for mobile nuclear cardiology for instance, the market is set on variable angulation dual heads cameras. These cameras are suited for all general applications and their cost effectiveness is optimized. Now, all major companies have such a camera in their of products. But, the big question in nuclear medicine is about the future of coincidence imaging for the monitoring of treatments in oncology. Many companies are focused on WIP assessments to find out the right crustal thickness to perform both high energy FDG procedures and low energy Tc procedures, with the same SPECT camera. The classic thickness is 3/8''. Assessments are made with 1/2'', 5/8'' or 3/4'' crystals. If FDG procedures proved to be of great interest in oncology, it may lead to the design of a dedicated SPECT camera with a 1'' crustal. Due to the short half of FDG, it may be the dawning of slip ring technology. (e.g. Varicam from Elscint). The three small heads camera market seems to be depressed. Will the new three large heads camera unveiled by Picker, reverse that trend? The last important topic in nuclear medicine is the emergence of new flat digital detectors to get rid of the old bulky ones. Digirad is the first company to manufacture a commercial product based on that technology. Bichron, Siemens and General Electric are working on that development, too. But that technology is very expensive and the market for digital detection in nuclear medicine is not as large as the market in digital detection in radiology. (author)

    A portable, computerized nuclear probe designed to measure left ventricular function is described. The ejection fraction was reproducible and correlated well with that obtained by means of a gamma camera. The limitations of the machine are that it measures the global, rather than the segmental, function of the left ventricle and, when discrete large areas of regional dysfunction occur, the global ejection fraction may be overestimated. An advantage is that continuous beat-to-beat measurements are easily performed and displayed.

    Sufficient work has now been done, on a world-wide basis, to justify confidence that full decommissioning of nuclear installations, both plant and reactors, can be carried out safely and efficiently. Projects in several countries should confirm this in the next few years. In the UK, good progress has been made with the WAGR and supporting development work is finding solutions to resolve uncertainties. Estimates from several sources suggest that decommissioning costs can be kept to an acceptable level.

    2 1/2 years ago a consultation group was formed to help the Section for Social Questions of the Council of Churches in the Netherlands, to answer questions in the area of nuclear energy. During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches. Technical and economic information and the most important social questions are discussed. (C.F.)

    James, A.E. Jr.; Squire, L.F.

    1977-01-01

    The book presents a number of fundamental imaging principles in nuclear medicine. The fact that low radiation doses are sufficient for the study of normal and changed physiological functions of the body is an important advancement brought about by nuclear medicine. The possibility of quantitative investigations of organs and organ regions and of an assessment of their function as compared to normal values is a fascinating new diagnostic dimension. The possibility of comparing the findings with other pathological findings and of course control in the same patient lead to a dynamic continuity with many research possibilities not even recognized until now. The limits of nuclear scanning methods are presented by the imprecise structural information of the images. When scintiscans are compared with X-ray images or contrast angiography, the great difference in the imaging of anatomical details is clearly seen. But although the present pictures are not optimal, they are a great improvement on the pictures that were considered clinically valuable a few years ago. (orig./AJ) [de

    This book fills a gap in current literature by covering the increasing nuclear physics content of various A-level syllabuses. In section 1 we outline the background and early development of the subject, in section 2 we deal with nuclear properties and theories at a level suitable for the pre-university student. The majority of topics have been treated with the limited use of mathematics, this necessitating some simplification which we hope to have accomplished without undue error. A few topics have been developed mathematically, to some extent, e.g. series decay. While it is the purpose of a book at this level to introduce the reader to the facts and theories of nuclear physics, we have to recognise that any teacher of science, at any level, must attempt to instill in the young scientist a sense of responsibility and an understanding of the problems attendant on the technological applications are important. These problems have been touched on in the text but we hope the student will be persuaded to read further; for this purpose we have added a short list of suggested additional reading. A selection of A-level past paper questions has been included. (author)

    During September and October 2001, 15 events were recorded on the first grade and 1 on the second grade of the INES scale. The second grade event is in fact a re-classification of an incident that occurred on the second april 2001 at Dampierre power plant. This event happened during core refueling, a shift in the operation sequence led to the wrong positioning of 113 assemblies. A preliminary study of this event shows that this wrong positioning could have led, in other circumstances, to the ignition of nuclear reactions. Even in that case, the analysis made by EDF shows that the consequences on the staff would have been limited. Nevertheless a further study has shown that the existing measuring instruments could not have detected the power increase announcing the beginning of the chain reaction. The investigation has shown that there were deficiencies in the control of the successive operations involved in refueling. EDF has proposed a series of corrective measures to be implemented in all nuclear power plants. The other 15 events are described in the article. During this period 121 inspections have been made in nuclear facilities. (A.C.)

  14. Nuclear fuels

    International Nuclear Information System (INIS)

    2008-01-01

    The nuclear fuel is one of the key component of a nuclear reactor. Inside it, the fission reactions of heavy atoms, uranium and plutonium, take place. It is located in the core of the reactor, but also in the core of the whole nuclear system. Its design and properties influence the behaviour, the efficiency and the safety of the reactor. Even if it represents a weak share of the generated electricity cost, its proper use represents an important economic stake. Important improvements remain to be made to increase its residence time inside the reactor, to supply more energy, and to improve its robustness. Beyond the economical and safety considerations, strategical questions have to find an answer, like the use of plutonium, the management of resources and the management of nuclear wastes and real technological challenges have to be taken up. This monograph summarizes the existing knowledge about the nuclear fuel, its behaviour inside the reactor, its limits of use, and its R and D tracks. It illustrates also the researches in progress and presents some key results obtained recently. Content: 1 - Introduction; 2 - The fuel of water-cooled reactors: aspect, fabrication, behaviour of UO 2 and MOX fuels inside the reactor, behaviour in loss of tightness situation, microscopic morphology of fuel ceramics and evolution under irradiation - migration and localisation of fission products in UOX and MOX matrices, modeling of fuels behaviour - modeling of defects and fission products in the UO 2 ceramics by ab initio calculations, cladding and assembly materials, pellet-cladding interaction, advanced UO 2 and MOX ceramics, mechanical behaviour of the fuel assembly, fuel during a loss of coolant accident, fuel during a reactivity accident, fuel during a serious accident, fuel management inside reactor cores, fuel cycle materials balance, long-term behaviour of the spent fuel, fuel of boiling water reactors; 3 - the fuel of liquid metal fast reactors: fast neutrons radiation

    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.

A history of political decisions on weapon development is given, along with a what if analysis of other options. The lesson of these two books is that it has proved considerably easier to live with nuclear weapons and the Soviet Union than anyone expected forty years ago. It is all the easier if arms control issues, based on worst case analyses, are kept in their place, which is firmly in the background of the overall conduct of foreign policy

    Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, with an emphasis on the huge developments that took place around the time of World War II, and that underlie the physics involved in designs of nuclear explosions, controlled nuclear energy, and nuclear fusion. The review then moves to focus on modern applications of these concepts, including the basic concepts and diagnostics developed for the forensics of nuclear explosions, the nuclear diagnostics at the National Ignition Facility, nuclear reactor safeguards, and the detection of nuclear material production and trafficking. The review also summarizes recent developments in nuclear geophysics and nuclear medicine. The nuclear geophysics areas discussed include geo-chronology, nuclear logging for industry, the Oklo reactor, and geo-neutrinos. The section on nuclear medicine summarizes the critical advances in nuclear imaging, including PET and SPECT imaging, targeted radionuclide therapy, and the nuclear physics of medical isotope production. Each subfield discussed requires a review article unto itself, which is not the intention of the current review; rather, the current review is intended for readers who wish to get a broad understanding of applied nuclear physics.

    The Single Channel Trip System for the Dungeness B AGRs in the United Kingdom has enabled Nuclear Electric to enhance the performance of each of the twin reactors progressively towards the design figure of 660MW. The unique self-testing dynamic nature of the microprocessor-based ISAT system was one of the key factors in satisfying the UK Regulator that the system met the demanding requirements of the Dungeness B application, and current operational and maintenance experience is very encouraging. Systems based on the ISAT principle have application in reactor protection systems throughout the world. (Author)

    The nuclear stethoscope consisting of radiocardiography and data processing by a microcomputer was introduced with respect to its outline, reliability and clinical application. Ejection fractions (EF) obtained by this device showed a satisfactory correlation with values obtained by the cardiac pool multigate (MUGA) method using a scinticamera and minicomputer, with a slight tendency to overestimation. They showed a good correlation with left ventriculography, accompanied by a slight tendency to underestimation. The reproducibility of this device was also satisfactory. Clinically, EF values during exercise in ischemic heart disease were well correlated with those obtained by the MUGA method. This device permitted real time evaluation of left ventricular function and was highly reliable.

    The reactor core of nuclear reactors usually is composed of individual elongated fuel elements that may be vertically arranged and through which coolant flows in axial direction, preferably from bottom to top. With their lower end the fuel elements gear in an opening of a lower support grid forming part of the core structure. According to the invention a locking is provided there, part of which is a control element that is movable along the fuel element axis. The corresponding locking element is engaged behind a lateral projection in the opening of the support grid. The invention is particularly suitable for breeder or converter reactors. (orig.) [de

    1991-01-01

    Nuclei, like more familiar mechanical systems, undergo simple vibrational motion. Among these vibrations, sound modes are of particular interest since they reveal important information on the effective interactions among the constituents and, through extrapolation, on the bulk behaviour of nuclear and neutron matter. Sound wave propagation in nuclei shows strong quantum effects familiar from other quantum systems. Microscopic theory suggests that the restoring forces are caused by the complex structure of the many-Fermion wavefunction and, in some cases, have no classical analogue. The damping of the vibrational amplitude is strongly influenced by phase coherence among the particles participating in the motion. (author)

    Sufficient work has now been done, on a world-wide basis, to justify confidence that full decommissioning of nuclear installations, both plant and reactors, can be carried out safely and efficiently. Projects in several countries should confirm this in the next few years. In the United Kingdom, good progress has been made with the Windscale Advanced Gas-cooled Reactor and supporting development work is finding solutions to resolve uncertainties. Estimates from several sources suggest that decommissioning costs can be kept to an acceptable level. (author)

    Nuclear dualism is a characteristic feature of the ciliated protozoa. Tetrahymena have two different nuclei in each cell. The larger, polyploid, somatic macronucleus (MAC) is the site of transcriptional activity in the vegetatively growing cell. The smaller, diploid micronucleus (MIC) is transcriptionally inactive in vegetative cells, but is transcriptionally active in mating cells and responsible for the genetic continuity during sexual reproduction. Although the MICs and MACs develop from mitotic products of a common progenitor and reside in a common cytoplasm, they are different from one another in almost every respect.

    This paper discusses the Department of Energy's (DOE) procedures for annually assessing the adequacy of the fee that utilities pay for disposal of spent (used) nuclear fuel. In a June 1990 report, it was recommended, among other things, that the Congress authorize DOE to automatically adjust the fee each year on the basis of an inflation index. At that time, DOE also favored fee indexing; however, it subsequently reversed its position. Because of this change, it is now believe that Congress should require DOE to index the fee to the rate of inflation

    A nuclear reactor with control rods in channels between fuel assemblies wherein the fuel assemblies incorporate guide rods which protrude outwardly into the control rod channels to prevent the control rods from engaging the fuel elements. The guide rods also extend back into the fuel assembly such that they are relatively rigid members. The guide rods are tied to the fuel assembly end or support plates and serve as structural members which are supported independently of the fuel element. Fuel element spacing and support means may be attached to the guide rods. 9 claims

    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.)

    Reference is made to auxiliary means of cooling the nuclear fuel clusters used in light or heavy water cooled nuclear reactors. One method is to provide one or more spray cooling tubes. From holes in the side walls of those tubes coolant water may be sprayed laterally into the cluster against the rods. The flow of main coolant may thus be supplemented or even replaced by the auxiliary coolant. A difficulty, however, is that only those fuel rods close to a spray cooling tube can readily be reached by the auxiliary coolant. In the arrangement described, where the fuel rods are spaced apart by transverse grids, at least one of the interspaces between the grids is provided with an axially extending auxiliary coolant conduit having lateral holes through which an auxiliary coolant is sprayed into the cluster. A deflector is provided that extends from a transverse grid into a position in front of the holes and deflects auxiliary coolant on to parts of the fuel rods otherwise inaccessible to the auxiliary coolant. The construction of the deflector is described. (U.K.)

    A nuclear reactor has an upper and a lower grid plate. Protrusions project from the upper grid plate. Fuel assemblies having end fittings fit between the grid plates. An arrangement is provided for accepting axial forces generated during the operation of the nuclear reactor by the flow of the cooling medium and thermal expansion and irradiation-induced growth of the fuel assembly, which comprises rods. Each fuel assembly rests on the lower grid plate and its upper end is elastically supported against the upper grid plate by the above-mentioned arrangement. The arrangement comprises four (for example) torsion springs each having a torsion tube and a torsion bar nested within the torsion tube and connected at one end thereto. The other end of the torsion bar is connected to an associated one of four lever arms. The torsion tube is rigidly connected to the other end fitting and the springs are disposed such that the lever arms are biassed against the protrusions. (author)

    In a strange turn of history, the threat of global nuclear war has gone down, but the risk of a nuclear attack has gone up. The danger of nuclear terrorism and ways to thwart it, tackle it and manage it in the event of an attack is increasingly gaining the attention of nuclear analysts all over the world. There is rising awareness among nuclear experts to develop mechanisms to prevent, deter and deal with the threat of nuclear terrorism. Nuclear specialists are seeking to develop and improve the science of nuclear forensics so as to provide faster analysis during a crisis. Nuclear forensics can play an important role in detecting illicit nuclear materials to counter trafficking in nuclear and radiological materials. An effective nuclear forensic and attribution strategy can enable policy makers, decision makers and technical managers to respond to situations involving interception of special nuclear materials

    Full Text Available Nuclear weapons have played an important role in China's national strategy. China’s nuclear doctrine has a very strong continuity. Nevertheless, China has made readjustments in its nuclear doctrine according to the changes of its internal and external situation and its general strategic threat perception. China’s nuclear doctrine has experienced a process of evolution from anti-nuclear blackmail to minimum deterrence. There are five major parts in China's nuclear doctrine: policy of declaration, nuclear development, nuclear deployment, nuclear employment, and nuclear disarmament. Because China is faced with a different situation from other nuclear powers and has its own strategic culture, China has a nuclear doctrine with its own characteristics. China’s nuclear doctrine has been affiliated with and has served the national development strategy, national security strategy, national defense policy and military strategy of China.

    The Sizewell 'B' Nuclear Power Station, the first in a new family of PWR (Pressurised Water Reactor) stations in the UK, is currently under construction on the Suffolk coast. One of the first civil engineering tasks associated with the power station construction was the necessity to lower the water table by 17-18 m over an area of approximately 8 hectares to allow the excavation for the foundations to be carried out in the dry. The way chosen to do this was to construct a diaphragm wall around the site area. This had the least effect on surrounding sites -the Sizewell-A station and various nature reserves and wetlands. The reasons for the choice of method are discussed. Following the construction of the wall the water was pumped out from within the diaphragm wall in January 1988. (author)

Stewart's chain reaction of 1923, Olaf Stapeldon's mushroom cloud of 1930 and Hans Dominik's tactical atomic weapon of 1927 are briefly reviewed as well as a forecast of the Three Mile island accident. These examples show that although the trained imagination of writers can approach the truth none can claim accuracy in predicting the facts. Where they do approach the truth is in the prediction of the consequences of the discoveries, social as well as military, of unlimited energy and of unlimited disasters. (U.K.)

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

    This paper reviews the Department of Energy's management of underground single-shell waste storage tanks at its Hanford, Washington, site. The tanks contain highly radioactive and nonradioactive hazardous liquid and solid wastes from nuclear materials production. Hundreds of thousands of gallons of these wastes have leaked, contaminating the soil, and a small amount of leaked waste has reached the groundwater. DOE does not collect sufficient data to adequately trace the migration of the leaks through the soil, and studies predicting the eventual environmental impact of tank leaks do not provide convincing support for DOE's conclusion that the impact will be low or nonexistent. DOE can do more to minimize the environmental risks associated with leaks. To reduce the environmental impact of past leaks, DOE may be able to install better ground covering over the tanks to reduce the volume of precipitation that drains through the soil and carries contaminants toward groundwater

    Purpose: To facilitate and accelerate a leakage test of valves of a main steam pipe by adding a leakage test partition valve thereto. Constitution: A leakage testing partition valve is provided between a pressure vessel for a nuclear reactor and the most upstream side valve of a plurality of valves to be tested for leakage, a testing branch pipe is communicated with the downstream side of the partition valve, and the testing water for preventing leakage is introduced thereto through the branch pipe. Since main steam pipe can be simply isolated by closing the partition valve in the leakage test, the leakage test can be conducted without raising or lowering the water level in the pressure vessel, and since interference with other work in the reactor can be eliminated, the leakage test can be readily conducted parallel with other work in the reactor in a short time. Clean water can be used without using reactor water as the test water. (Yoshihara, H.)

An unsymmetrical arrangement in the lattice is provided, if necessary also by insertion of special rods for these additions. It is proposed to arrange the burnable poisons in fuel elements taken over from a previous burn-up cycle and to distribute them, going out from the side facing the control rods, over not more than 20% of the lenth of the fuel elements.

    As required by the Nuclear Waste Policy Act of 1982, the Department of Energy is to annually determine whether the waste disposal fee will produce sufficient revenues to offset the total estimated costs of the waste disposal program. In its June 1987 assessment, DOE recommended that the fee remain unchanged even though its analysis showed that at an inflation rate of 4 percent the current fee would result in end-of-program deficits ranging from $21 billion to $76 billion in 2085. The 1988 assessment calls for reduced total costs because of program changes. Thus, DOE may be able to begin using a realistic inflation rate in determining fee adequacy in 1988 without proposing a major fee increase

    Each year, nuclear power plants, businesses, hospitals, and universities generate more than 1 million cubic feet of hardware, rags, paper, liquid waste, and protective clothing that have been contaminated with radioactivity. While most of this waste has been disposed of in facilities in Nevada, South Carolina, and Washington state, recent legislation made the states responsible - either individually, or through groups of states called compacts - for developing new disposal facilities. This paper discusses the states' progress and problems in meeting facility development milestones in the law, federal and state efforts to resolve issues related to mixed waste (low-level waste that also contains hazardous chemicals) and waste with very low levels of radioactivity, and the Department of Energy's progress in discharging the federal government's responsibility under the law to manage the most hazardous low-level waste

As in the year before the pool can reckon with a stable gross premium yield around 175 million marks. The revival of the US dollar has played a decisive role in this development. In 1993 in the domestic market, the DKVG offered policies for 22 types of property risk and 43 types to third-party risk, operating with a gross target premium of 65 million marks and 16 million marks, respectively. The DKVG also participated in 540 foreign insurance contracts. (orig./HSCH) [de

  14. TL detectors for gamma-ray dose measurements in critically accidents

    Full text: Determination of gamma-ray dose in mixed neutron + gamma-ray fields is still a challenging 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 dosimeter responses to gamma-rays. To reduce all these influences, design of dosemeter holders is of special importance. In this work, several types of thermoluminescent detectors (TLD) placed in different holders used for gamma-ray dose determination in mixed fields were examined. Dosemeters were from three different institutions: Ruder Boscovic 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. At that exercise three accidental scenarios were reproduced: bare reactor, free evolution; lead shielded reactor, steady state; and lead shielded reactor, free evolution. In each irradiation dosemeters were exposed placed on the front of phantom and 'free-in-air'. Also, dosemeters were irradiated in a pure gamma ray field of 60 Co source. Following types of TLDs were used: 7 LiF (TLD-700), CaF 2 :Mn and AI 2 O 3 :Mg,Y - all from RBI; CaF 2 :Mn from JSI and 7 LiF (TLD-700) from ARN. Reported doses were compared with the reference values as well as with the mean participants' values. 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. (author)

    Fuel is one of the essential components in a reactor. It is within that fuel that nuclear reactions take place, i.e. fission of heavy atoms, uranium and plutonium. Fuel is at the core of the reactor, but equally at the core of the nuclear system as a whole. Fuel design and properties influence reactor behavior, performance, and safety. Even though it only accounts for a small part of the cost per kilowatt-hour of power provided by current nuclear power plants, good utilization of fuel is a major economic issue. Major advances have yet to be achieved, to ensure longer in-reactor dwell-time, thus enabling fuel to yield more energy; and improve ruggedness. Aside from economics, and safety, such strategic issues as use of plutonium, conservation of resources, and nuclear waste management have to be addressed, and true technological challenges arise. This Monograph surveys current knowledge regarding in-reactor behavior, operating limits, and avenues for R and D.

    International Nuclear Information System (INIS)

    1979-01-01

    In Germany the issue of nuclear weapons proliferation has attracted scant attention. Most potential nuclear weapon states are important trade partners of the FRG and, since further proliferation of nuclear weapons could worsen conflicts involving these, it should be in the FRG's interest to limit proliferation. The security of the FRG is also dependent on the common interest of the great powers to avoid nuclear war. The contradictory positions of Usa and the USSR on nuclear weapons policy regarding themselves and non-nuclear weapon states encourages less developed countries to see nuclear weaponry as useful. The NPT and IAEA safeguards have only limited inhibiting effect. The nuclear export policy of the FRG has been dominated by short term economic advantage, neglecting the negative long term effects of decreased political stability. The FRG should formulate a policy based on self-restraint, positive stimuli and extension of controls, using its economic strength to deter proliferation. (JIW)

    The objective of safeguards is the timely detection of diversion of significant quantities of nuclear material from peaceful nuclear activities to the manufacture of nuclear weapons or of other nuclear explosive devices or for purposes unknown, and deterrence of such diversion by the risk of early detection. The safeguards system should be designed to provide credible assurances that there has been no diversion of declared nuclear material and no undeclared nuclear material and activities.

    Within an unstable international environment and an unpredictable future, nuclear weapons will continue to play a major role in defense policies. Indeed, since disarmament currently seems an unlikely objective, nuclear weapons remain as a security guarantee. Within this context, talk of the global abolition of nuclear weapons remains essentially rhetorical and the supposed link between disarmament and non-proliferation is a tenuous one. The foremost purpose of both disarmament and nuclear deterrence must be security

    2014-05-09

    This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

    The increasing number of accidents with nuclear submarines is a worriment to the general public. Five nuclear submarines are resting on the bottom of the North Atlantic. Design information on nuclear propulsion plants for submarines is classified. The author describes a potential generic nuclear submarine propulsion plant. Design information from the civilian nuclear industry, nuclear power plants, research reactors, nuclear cargo vessels and nuclear propelled icebreakers are used for illustration of relevant problems. A survey is given of nuclear submarines. Factors influencing the accident risks and safety characteristics of nuclear submarines are considered, and potential accident scenarios are described. The fission product content of the nuclear plant can be estimated, '' source terms'' can be guessed and potential release rates can be judged. The mechanisms of dispersion in the oceans is reviewed and compared with the dumping of radioactive waste in the Atlantic and other known releases. 46 refs., 49 figs., 14 tabs

    Full text: The control of the personal exposition in the public University is done by the Centre of Nuclear Research since 1999. A look at the last years permitted to note the increase in the Personal Dosimeter users. In this work we study the annual collective dose, the annual effective dose average and the different dose in each University area between 2002-2005. The annual effective dose limit for the Nuclear Regulatory Authority (Autoridad Reguladora Nuclear), are the suggested by the International Commission of Radiological Protection (ICRP). The actual application of the Basics Principles of Radiological Protection demand exposition levels as low as reasonable achievable (ALARA) considering economics and social factors. In this way we decrease the probability to induce illness in the expose personal and their descendants. The different dependences of the University where the service is given are: Faculty of Medicine (Radiology, Oncology, Clinical Oncology, Nuclear Medicine), Faculty of Chemistry (Radiochemistry), Faculty of Odontology (Radiology), Faculty of Veterinary (Radiology) and Faculty of Sciences (Centre of Nuclear Research). The number of users between 2002-2006 varied from 292 in year 2002 to 329 in the year 2006. We see a maximum of persons in the year 2004. The annual collective dose have been changing too, the lowest was 0.13 Sv.person in the year 2002 and the highest was 0.21 Sv.person in the year 2005. The annual collective dose permits the evaluation of the radiological impact of the radiation ionising manipulation in the University. In these 5 years the 96% of the annual effective dose average were under 4 mSv, and the 76% were smaller than the minimum detectable limit. This 76% were obtained in teach and researches areas. In the 4% higher than 4 mSv we can find areas where works with open radioactive sources like: Nuclear Medicine and Radiochemistry (Faulted de Pumice). In these places we detect annual effective doses of 15 mSv, these levels

  6. Nuclear regulation

    International Nuclear Information System (INIS)

    1990-04-01

    Because of an accidental release in 1986 of low-level waste stored at the Wright-Patterson Air Force Base, Ohio, several individuals inhaled small amounts of a radioactive substance. GAO examined the Nuclear Regulatory Commission's oversight of the Department of Defense's use, handling, and disposal of radioactive material and found that no comprehensive DOD waste disposal program exists and none of the three services knows the full extent of its low-level radioactive waste disposal problems. Throughout the 1980s, the Army and the Air Force had, on occasion, been banned from disposal sites for failing to comply with federal and state requirements. By December 1992, two of the three sites now used by DOD to disposed of waste will close, and only a limited number of new sites may be available for several years. In the interim, DID will pay substantial surcharges to dispose of waste. After January 1993, DOD will have to comply with disposal requirements for as many as 16 sites or store waste on-site pending the availability of new sites. This report discusses how GAO believes DOD needs to take full advantage of the time between now and January 1993 to establish a low-level radioactive waste disposal program. DOD also needs to work with other federal agencies, compacts, and states to determine the feasibility of dedicating a portion of one or more disposal sites for the government's use

  7. Nuclear fusion

    International Nuclear Information System (INIS)

    Huber, H.

    1978-01-01

    A comprehensive survey is presented of the present state of knowledge in nuclear fusion research. In the first part, potential thermonuclear reactions, basic energy balances of the plasma (Lawson criterion), and the main criteria to be observed in the selection of appropriate thermonuclear reactions are dealt with. This is followed by a discussion of the problems encountered in plasma physics (plasma confinement and heating, transport processes, plasma impurities, plasma instabilities and plasma diagnostics) and by a consideration of the materials problems involved, such as material of the first wall, fuel inlet and outlet, magnetic field generation, as well as repair work and in-service inspections. Two main methods have been developed to tackle these problems: reactor concepts using the magnetic pinch (stellarator, Tokamak, High-Beta reactors, mirror machines) on the one hand, and the other concept using the inertial confinement (laser fusion reactor). These two approaches and their specific problems as well as past, present and future fusion experiments are treated in detail. The last part of the work is devoted to safety and environmental aspects of the potential thermonuclear aspects of the potential thermonuclear reactor, discussing such problems as fusion-specific hazards, normal operation and potential hazards, reactor incidents, environmental pollution by thermal effluents, radiological pollution, radioactive wastes and their disposal, and siting problems.

  8. Nuclear security

    International Nuclear Information System (INIS)

    1991-12-01

    This paper reports that despite their crucial importance to national security, safeguards at the Department of Energy's (DOE) weapons facilities may be falling short. DOE security inspections have identified many weaknesses, including poor performance by members of DOE's security force, poor accountability for quantities of nuclear materials, and the inability of personnel to locate documents containing classified information. About 13 percent of the 2,100 identified weakness resulted in DOE inspectors giving out unsatisfactory security ratings; another 38 percent led to marginal ratings. In addition, DOE's centralized safeguards and security information tracking system lacks current data on whether DOE field offices have corrected the identified weaknesses. Without reliable information, DOE has no way of knowing whether timely action was taken to correct problems, nor can it determine whether weaknesses are systematic. DOE has tried to minimize the impact of these security weaknesses at its facilities by establishing multiple layers of protection measures and instituting interim and compensatory measures for identified weaknesses. DOE is planning enhancements to the centralized tracking system that should improve its reliability and increase its effectiveness

    In a nuclear reactor (e.g. one having coolant down-flow through a core to a hearth below) thermal insulation (e.g. of a floor of the hearth) comprises a layer of bricks and a layer of tiles thereon, with smaller clearances between the tiles than between the bricks but with the bricks being of reduced cross-section immediately adjacent the tiles so as to be surrounded by interconnected passages, of relatively large dimensions, constituting a continuous chamber extending behind the layer of tiles. By this arrangement, lateral coolant flow in the inter-brick clearances is much reduced. The reactor core is preferably formed of hexagonal columns, supported on diamond-shaped plates each supported on a pillar resting on one of the hearth-floor tiles. Each plate has an internal duct, four upper channels connecting the duct with coolant ducts in four core columns supported by the plate, and lower channels connecting the duct to a downwardly-open recess common to three plates, grouped to form a hexagon, at their mutually-adjacent corners. This provides mixing, and temperature-averaging, of coolant from twelve columns

  10. Nuclear standards

    Fichtner, N.; Becker, K.; Bashir, M.

    1981-01-01

    This compilation of all nuclear standards available to the authors by mid 1980 represents the third, carefully revised edition of a catalogue which was first published in 1975 as EUR 5362. In this third edition several changes have been made. The title has been condensed. The information has again been carefully up-dated, covering all changes regarding status, withdrawal of old standards, new projects, amendments, revisions, splitting of standards into several parts, combination of several standards into one, etc., as available to the authors by mid 1980. The speed with which information travels varies and requires in many cases rather tedious and cumbersome inquiries. Also, the classification scheme has been revised with the goal of better adjustment to changing situations and priorities. Whenever it turned out to be difficult to attribute a standard to a single subject category, multiple listings in all relevant categories have been made. As in previous editions, within the subcategories the standards are arranged by organization (in Categorie 2.1 by country) alphabetically and in ascending numerical order. It covers all relevant areas of power reactors, the fuel cycle, radiation protection, etc., from the basic laws and governmental regulations, regulatory guides, etc., all the way to voluntary industrial standards and codes of pratice.

    A built-up image illustrating heart activity within the cardiac cycle is produced by simultaneously displaying a plurality of memory channels which accumulate respectively the amount of radioactivity detected within a cardiac chamber during successive intervals throughout the cardiac cycle. The parallel lines of a raster scan display correspond respectively to the memory channels. The count stored in a particular memory channel causes the video signal for the corresponding line to be maintained at a binary level for a corresponding time interval thus generating a bar graph in which the length of each bar indicates the amount of radioactivity sensed during the corresponding interval of the cardiac cycle. As each memory channel accumulates radioactivity data with each successive cardiac cycle, each bar displayed in the bar graph lengthens to indicate the cumulative activity until an interpretable curve is obtained. The invention relates generally to the field of nuclear medicine and, more specifically, to diagnostic techniques of analyzing blood flow through the heart by detecting radioactivity from radioisotopes injected into the bloodstream

    Purpose: To obtain an optimum structural arrangement of IRM having a satisfactory responsibility to the inoperable state of a nuclear reactor and capable of detecting the reactor power in an averaged manner. Constitution: As the structural arrangement of IRM, from 6 to 16 even number of IRM are bisected into equial number so as to belong two trip systems respectively, in which all of the detectors are arranged at an equal pitch along a circumference of a circle with a radius rl having the center at the position of the central control rod in one trip system, while one detector is disposed near the central control rod and other detectors are arranged substantially at an equal pitch along the circumference of a circle with a radius r2 having the center at the position for the central control rod in another trip system. Furthermore, the radius r1 and r2 are set such that r1 = 0.3 R, r2 = 0.5 R in the case where there are 6 IRM and r1 = 0.4 R and R2 = 0.8 R where there are eight IRM where R represents the radius of the reactor core.

    The spleen is a sinusoidal vascular filter that is an integral part of the reticuloendothelial system and is the largest single lymphoid organ in the body. Thus it has important scavenging and immunologic functions in humans. It is also a site for normal hematopoiesis in humans during the third to sixth months of gestation. Solenic hematopoiesis does occur normally in adult animals of other species (for instance, mouse, rat, rabbit), but it is seen postnatally in humans only when they have certain hematologic disorders such as myelofibrosis with myeloid metaplasia and severe hemolytic anemias. In its role as a reticuloendothelial organ the adult human spleen serves as a vascular scavenger. Arterial blood filters through a network of arterioles, cords, and sinuses in a closed system that requires the blood cells to be pliable and brings them into intimate contact with macrophages suspended on the reticulin stroma of the cords. Erythrocyte culling and pitting functions as described by Crosby result in a transient retention of immature circulating erythroid cells until residual intracellular nuclear fragments have been extruded. The increased risk for overwhelming infection in children and adults whose spleen have been removed for reasons other than acute trauma would appear to be caused by the loss of both its phagocytic and its immunologic (antibody-producing) contributions to the monitoring of the circulating blood. This paper reports that the ability of the spleen to phagocytose intravascular foreign particles and to recognize and destroy damaged erythrocytes is the basis for the current use of radiopharmaceuticals in spleen scintigraphy

  15. Nuclear decisions

    International Nuclear Information System (INIS)

    Fischhoff, B.

    1991-01-01

    This attempts to identify the role of judgmental processes in various nuclear arms/war decisions. That task analysis is done with some confidence. The next two steps, diagnosing potential weaknesses in those judgments and suggesting ameliorative procedures, are done with increasing timidity. The empirical research base is not (ever) as large as one would like. It is particularly weak with regard to studies of experts forced to go beyond hard data and rely on intuitive judgments within their field of expertise. further evidence is needed to substantiate the claim that experts think like everyone else unless they have had the opportunity to master a particular kind of judgment as a learned skill. Although there is both theoretical and empirical reason to believe that various forms of decision aiding are possible, the high stakes involved mandate caution before proposing any intervention. Ineffective steps may make matters worse if they raise confidence without improving performance, or if they disrupt the cognitive ecology within which decision makers are accustomed to functioning, so that they lose touch with their own imperfect intuitions without acquiring viable alternatives

  16. Nuclear waste

    International Nuclear Information System (INIS)

    1990-07-01

    The state of Nevada opposed DOE's development of a nuclear waste repository at Yucca Mountain. As a result, disputes have arisen over how Nevada has spent financial assistance provided by DOE to pay the state's repository program costs. This report reviews Nevada's use of about $32 million in grant funds provided by DOE through June 1989 and found that Nevada improperly spent about $1 million. Nevada used as much as $683,000 for lobbying and litigation expenses that were unauthorized or were expressly prohibited by law, court decision, or grant terms; exceeded a legislative spending limit on socioeconomic studies by about $96,000; and used, contrary to grant terms, about $275,000 from one grant period to pay expenses incurred in the prior year. Also, Nevada did not always exercise adequate internal controls over grant funds, such as timely liquidation of funds advanced to contractors. A permissive approach to grant administration by DOE contributed to Nevada's inappropriate use of grant funds

  18. Nuclear disarmament and peaceful nuclear technology

    International Nuclear Information System (INIS)

    Taylor, T.B.

    1989-01-01

    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

    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

  11. Security with nuclear weapons

    International Nuclear Information System (INIS)

    Karp, R.C.

    1991-01-01

    Recent improvements in East-West relations and the process of dramatic political change in Europe may result in unprecedented opportunities to reduce the global arsenal of nuclear weapons. Despite these welcome developments, the prospects for effectively controlling the spread of nuclear capability in the Third World have remained much less encouraging. The possibility of large reductions in nuclear weapons poses fundamental questions about their purpose. Why have some states chosen to acquire nuclear weapons? How and why have these decisions been maintained over time? Why have some states elected to approach, but not cross, the nuclear threshold? This book examines the commonalities and differences in political approaches to nuclear weapons both within and between three groups of states: nuclear, non-nuclear and threshold. The chapters explore the evolution of thinking about nuclear weapons and the role these weapons play in national security planning, and question the official security rationales offered by the nuclear weapon states for the maintenance of nuclear capabilities. For the non-nuclear weapon states, the book presents an analysis of alternative ways of assuring security and foreign policy effectiveness. For the threshold states, it examines the regional contexts within which these states maintain their threshold status. This book transcends traditional East-West approaches to analysis of nuclear issues by giving equal prominence to the issues of nuclear proliferation and non-nuclearism. The book also provides a comprehensive analysis of how current approaches to nuclear weapons have evolved both within and among the groups of countries under study

    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)

    Although United States Customs recently prevented 40 krytrons, fast triggers to start a nuclear fission detonation, from being exported, other countries have been able to acquire similar items without questions being asked. Nuclear power plants have been exported to Pakistan and it is expected that this will enable Pakistan to become the world's ninth nuclear weapons state. Not all current or potential nuclear weapons states have signed and ratified the Non-Proliferation Treaty. Some nuclear plant have been built in developing countries without proper International Atomic Energy Authority Control. It would seem that there is a general indifference to nuclear proliferation by some of the western nuclear countries. (UK)

  4. Potential for nuclear terrorism

    International Nuclear Information System (INIS)

    Jenkins, B.M.

    1977-05-01

    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

    Patterson, W.

    1978-01-01

    The Ontario Royal Commission on Electric Power Planning, chaired by Arthur Porter is reviewed. This interim report on nuclear power is relevant to nuclear power planning far beyond the confines of Ontario and discusses nuclear issues in the explicit context of electricity generation and use. Problems considered in the report include safety aspects of uranium mining, milling, and spent fuel disposal, the economic issues which affect nuclear planning and nuclear industry, and the proliferation issue.

  15. Nuclear terrorism and reality

    International Nuclear Information System (INIS)

    St Sauver, J.E.

    1983-01-01

    Unlike conventional terrorist violence, bona-fide nuclear terrorism is a self-publicizing phenomenon. It is a public event by the very scope of its impact. Apocalyptic and catastrophically destructive, a nuclear explosion is the ideal instrument of mass terror. Rational nuclear insurgents would not inform authorities that a nuclear device is about to be detonated. Advance warning of an impending nuclear explosion would reduce the maximum potential effectiveness of any response to such an event

    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.

    Beside new Ordinance on the control of nuclear material and special equipment ('Official Gazette' No. 15/08), from 2006 State Office for Nuclear Safety (SONS) adopted Ordinance on performing nuclear activities ('Official Gazette' No. 74/06) and Ordinance on special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety ('Official Gazette' No. 74/06), based on Nuclear Safety Act ('Official Gazette' No. 173/03). The Ordinance on performing nuclear activities regulates the procedure of notification of the intent to perform nuclear activities, submitting the application for the issue of a licence to perform nuclear activities, and the procedure for issuing decisions on granting a licence to perform a nuclear activity. The Ordinance also regulates the content of the forms for notification of the intent to perform nuclear activities, as well as of the application for the issue of a licence to perform the nuclear activity and the method of keeping the register of nuclear activities. According to the Nuclear Safety Act, nuclear activities are the production, processing, use, storage, disposal, transport, import, export, possession or other handling of nuclear material or specified equipment. The Ordinance on special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety regulates these mentioned conditions, whereas compliance is established by a decision passed by the SONS. Special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety are organizational, technical, technological conditions and established system of quality assurance. In 2007, State Office for Nuclear Safety finalized the text of new Ordinance on conditions for nuclear safety and protection with regard to the siting, design, construction, use and decommissioning of a facility in which a nuclear activity is
