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.

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.

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.

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

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

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 the models applied and the results consistency. To that aim, the 1. Regional Intercomparison Exercise was organized in 2005 in the frame of the RLA 9/049. The results of this exercise led to the 2. Regional Intercomparison Exercise in 2013, which was organized in the frame of the RLA 9/066 and coordinated by Autoridad Regulatoria Nuclear (ARN) of Argentina. Four simulated cases covering intakes of “1”3”1I, “1”3”7Cs and Tritium were proposed. The exercise counted with the participation of 19 centres from 13 countries. This report shows a complete analysis of the participant’s results in this 2nd. exercise, useful to test their skills and acquired knowledge, particularly in applying the IDEAS guidelines. It is important to highlight the improvement in the general performance of the participants. (authors) [es

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

Silva, M

2006-01-01

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

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: 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

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.

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.

Full Text Available Traditionally, the failure of Baron Nordenflicht’s mining expedition to Peru has been attributed to the negative attitude towards the mission supposedly displayed by the Peruvian authorities in general and Viceroy Francisco Gil y Lemos (1790-1796 in particular. 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. Este artículo refuta documentalmente esta versión, demostrando que dicho fracaso se debió a razones técnicas y no a supuestas trabas por parte de las autoridades virreinales.

Lecciones regulatorias de la quiebra de Lehman Brothers

Directory of Open Access Journals (Sweden)

William Black

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.

Internal dosimetry intercomparisons are essential for the verification of applied models and the consistency of results'. To that aim, the First Regional Intercomparison was organised in 2005, and that results led to the Second Regional Intercomparison Exercise in 2013, which was organised in the frame of the RLA 9/066 and coordinated by Autoridad Regulatoria Nuclear of Argentina. Four simulated cases covering intakes of (131)I, (137)Cs and Tritium were proposed. Ninteen centres from thirteen different countries participated in this exercise. This paper analyses the participants' results in this second exercise in order to test their skills and acquired knowledge, particularly in the application of the IDEAS Guidelines. It is important to highlight the increased number of countries that participated in this exercise compared with the first one and, furthermore, the improvement in the overall performance. The impact of the International Atomic Energy Agency (IAEA) Projects since 2003 has led to a significant enhancement of internal dosimetry capabilities that strengthen the radiation protection of workers. © The Author 2015.

La autoridad desde el psicoanálisis

CHARLES MELMAN

2005-01-01

Full Text Available Los intentos por realizar la igualdad entre los ciudadanos han demostrado ser utopías. La vida social sigue dividida entre amos y esclavos y el único progreso político de la democracia es que cualquier ciudadano pueda llegar a ocupar el lugar del amo. La autoridad conduce a un amor (servidumbre voluntaria y la distribución de lugares amo-esclavo perdura como una ley que obliga. Pero ahora el amo no está encarnado por una figura sino por un objeto: de la satisfacción, del goce, que ejerce un poder sin límite en virtud del cual ya no existirían tales lugares. La globalización es la universalización de ese poder. El rostro del objeto que habita la casa del Gobernador es único en Colombia: la coca. ¿Por qué no despenalizarla? Se demostraría que no afecta el número de consumidores y sí se libra al país de una economía fuera de la ley.

Full Text Available En este artículo se aclarará cómo el ejercicio de la autoridad en su conjunto, particularmente en la educación en el ámbito familiar, se encuentra en una crisis histórica que se ha acentuado en nuestros días. 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.

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.

Las reflexiones suscitadas por la teoría del pos-custodial mudaron las formas teóricas y prácticas de realizar el proceso de descripción, ahora dirigido a representar de forma normalizada diferentes entidades archivísticas: documentos, productores, funciones, instituciones de custodia entre otras. 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. La representación de los productores y su integración en los sistemas de información es una tarea fundamental en los nuevos contextos de la archivística posmoderna, orientada a la gestión, el acceso y la veracidad de la información. The information representation in the archives framework faces new challenges characterized by the paradigmatic transitions in the Archivistics.

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.

2011-01-01

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.

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.

2016-01-01

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.

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.

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

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.

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 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.

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.

Otros problemas habituales de la pediatría son el uso de formulaciones no aptas para niños, la falta de evidencia científica en cuanto a eficacia/seguridad para muchos medicamentos, el uso de medicamentos no aprobados por autoridades regulatorias y la influencia de otras patologías sobre el comportamiento FC. Estas condicionantes hacen que encontrar la dosis óptima de un medicamento en un niño, sea un reto en muchas terapias. Es fundamental conocer el comportamiento de los medicamentos en un organismo en constante desarrollo y maduración para lograr una terapéutica efectiva, segura y racional. Algunas herramientas como la farmacovigilancia y el monitoreo terapéutico de fármacos podrían ayudar a optimizar terapias en este escenario de incertidumbre.

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.

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

Full text: 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)

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.

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.

2008-01-01

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.

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 �

Regiane Lucas de Oliveira Garcêz

Full Text Available Resumo O trabalho objetiva analisar os processos de representação política não eleitoral que emergem do debate sobre o melhor modelo de escola para pessoas surdas. Investigamos como fontes de autoridade são acionadas por surdos ou pessoas com deficiência, especialmente aquelas relacionadas à presença física (identidades adscritivas e à autoafirmação das identidades (autoadscrição. As unidades de análise (claims foram extraídas de três arenas: de um grupo de lideranças surdas do Facebook, de uma audiência pública do Judiciário e da Conferência Nacional dos Direitos da Pessoa com Deficiência. Conclui-se que o corpo é uma fonte de autoridade tão importante quanto o discurso, que a língua de sinais revela uma dimensão de intraduzibilidade exposta pela presença e que os aspectos culturais das línguas de sinais promovem rupturas nas dinâmicas convencionais de representação.

Full Text Available Este trabajo intenta analizar las transformaciones de la autoridad en los jefes étnicos en la jurisdicción de la ciudad de San Salvador de Jujuy (Gobernación del Tucumán durante el siglo XVII. Parte de estas transformaciones estaban condicionadas por la concesión de encomiendas y la creación de los pueblos de indios y nuevas instituciones, como los cabildos indígenas. Estas circunstancias limitaron el poder de las antiguas autoridades, sin embargo a lo largo del siglo XVII surgieron nuevos cargos como el de cacique gobernador y nuevas formas de legitimación que intentaban contrarrestar estos cambios.This paper attempts to analyze some changes within the ethnic leaders' authority in the jurisdiction of San Salvador de Jujuy city ( Gobernación del Tucumán during the seventeenth century. Some of these changes were influenced by the granting of encomiendas and the creation of Indians towns and new institutions such as Indian cabildos. These circumstances limited the power of ancient authorities, however during the seventeenth century new offices, such as the cacique de Gobernador, and new forms of legitimacy emerged in order to counterbalance the above-mentioned changes.

ARTURO GINER FILLOL

2012-06-01

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

Full Text Available In the Argentinian cinema of the end of the 90’s and beginning of the 21st century, the representations of femininity and masculinity have become richer thanks to alternative visions, most frequently proposed by female directors. Natalia Smirnoff’s film Rompecabezas (Puzzle is a perfect example. It tells the story of an ordinary woman whose psychosexual awakening shakes up the invisible forces that had dictated her life up to that point. Rompecabezas explores the everlasting effect and influence on the patriarchal structures in constructing identity. The aim of this work, rooted in a gender perspective, is to study in what way both hierarchy and symbolic systems operate and to what extent Natalia Smirnoff provides us with a powerful (revision of transformation for women.En el cine argentino de finales de los años 90 y principios del siglo actual, las representaciones de la feminidad y la masculinidad se están enriqueciendo gracias a las visiones alternativas que nos ofrecen en su mayoría directoras.

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)

Thermal-hydraulic system computer codes are extensively used worldwide for analysis of nuclear facilities by utilities, regulatory bodies, nuclear power plant designers and vendors, nuclear fuel companies, research organizations, consulting companies, and technical support organizations. The computer code user represents a source of uncertainty that can influence the results of system code calculations. This influence is commonly known as the user effect' and stems from the limitations embedded in the codes as well as from the limited capability of the analysis to use the codes. Code user training and qualification is an effective means for reducing the variation of results caused by the application of the codes by different users. This paper describes a systematic approach to training code users who, upon completion of the training, should be able to perform calculations making the best possible use of the capabilities of best estimate codes. In other words, the program aims at contributing towards solving the problem of user effect. The 3D S.UN.COP (Scaling, Uncertainty and 3D COuPled code calculations) seminars have been organized as follow-up of the proposal to IAEA for the Permanent Training Course for System Code Users. Six seminars have been held at University of Pisa (2003, 2004), at The Pennsylvania State University (2004), at University of Zagreb (2005), at the School of Industrial Engineering of Barcelona (January-February 2006) and in Buenos Aires, Argentina (October 2006), being this last one requested by ARN (Autoridad Regulatoria Nuclear), NA-SA (Nucleoelectrica Argentina S.A) and CNEA (Comision Nacional de Energia Atomica). It was recognized that such courses represented both a source of continuing education for current code users and a mean for current code users to enter the formal training structure of a proposed 'permanent' stepwise approach to user training. The 3D S.UN.COP 2006 in Barcelona was successfully held with the attendance of 33

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.

Violência institucional, autoridade médica e poder nas maternidades sob a ótica dos profissionais de saúde

2013-11-01

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 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 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.

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

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

Full Text Available El virus del tumor mamario murino (MMTV es un retrovirus que se transmite durante la lactancia y que ha desarrollado estrategias para explotar y subvertir el sistema inmune. En un modelo de infección natural con MMTV hemos mostrado previamente que la infección causa incrementos tempranos y progresivos de células T regulatorias (Treg CD4+CD25+Foxp3+ específicas para el superantígeno (Sag viral en las placas de Peyer (PP. En este trabajo se evaluó si la depleción de las células Treg influencia la población de células CD8+ durante la infección con MMTV a través del amamantamiento. La depleción de las células Treg al día 6 de infección causó incrementos en el porcentaje y número absoluto de las células CD8+ en los ganglios y provocó un incremento en la intensidad de fluorescencia media del marcador de activación CD44 en esas células. Los incrementos en el número absoluto de las células CD8 se observaron en células con cadenas variables Vβ del receptor de las células T (TCR tanto reactivas como no reactivas al Sag. Previamente habíamos demostrado que la depleción de las células Treg al día 6 de infección disminuye la carga viral. Los resultados presentados en este trabajo sugieren que, al menos a partir del día 6 de infección con MMTV, las células Treg podrían tener un rol inhibiendo la generación de una respuesta CD8 antiviral.

Full Text Available Las autoridades regulatorias recomiendan el uso de técnicas de Resonancia Magnética Nuclear o técnicas serológicas para la determinación de la identidad de los antígenos presentes en las vacunas conjugadas. Con la aparición de las vacunas conjugadas multivalentes, se ha hecho necesario recurrir a técnicas inmunoquímicas con la utilización de anticuerpos monoclonales para aumentar la sensibilidad en la determinación de la identidad de los antígenos en dichas vacunas conjugadas. El objetivo del presente trabajo fue establecer las condiciones óptimas de trabajo que permitieran utilizar la técnica del Dot Blot para determinar la identidad de los antígenos en vacunas conjugadas de Streptococcus pneumoniae serotipo 19F. Para ello se estudiaron los tiempos de incubación, la influencia del reactivo en la solución de bloqueo; también las concentraciones óptimas del anticuerpo monoclonal y de los ingredientes farmacéuticos activos, así como los volúmenes de aplicación óptimos para estos y vacunas. Se utilizó un anticuerpo monoclonal contra el polisacárido capsular del serotipo 19F de neumococo. Las muestras empleadas en este trabajo fueron lotes de ingredientes farmacéuticos activos de conjugados de polisacárido capsular 19F y lotes de un candidato vacunal cubano conjugado heptavalente contra neumococos. Los resultados mostraron que para la determinación de la identidad antigénica fueron suficientes 10 µL de muestras de los principios activos a una concentración de 125 µg/mL e igual volumen para las vacunas heptavalentes. Quedó demostrado que una concentración de 1 µg/mL para el anticuerpo monoclonal y tiempos de incubación de 30 min a 37 °C fueron suficientes para la determinación. Estos resultados permiten concluir que quedaron establecidas las condiciones óptimas de trabajo para determinar la identidad antigénica por Dot Blot del polisacárido capsular de S. pneumoniae serotipo 19F presente en las vacunas

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.

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)

Desobediencia civil: la autoridad de la reflexión vs la autoridad civil

Maria José Urteaga Rodríguez

2016-06-01

Full Text Available ¿Puede la desobediencia civil justificarse moralmente? Este trabajo intenta dar una respuesta afirmativa a esta pregunta. 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.

Fortalecimiento de la función rectora de las autoridades sanitarias en las reformas del sector de la salud Strengthening the steering role of health authorities within the context of health sector reform

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 El tipo de policía y su relación con los escenarios de incertidumbre proclives a la violencia constituye un esfuerzo principal de este estudio. 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

Full Text Available El artículo analiza la evolución de la regulación del sector eléctrico en Argentina y Brasil entre 1890 y 1960. Desde la instalación de las primeras usinas eléctricas a fines del siglo diecinueve hasta los años treinta, el control de las empresas concesionarias estuvo a cargo de las autoridades municipales en ambos países. No obstante, la similar estructura de los sistemas eléctricos en Argentina y en Brasil, la participación del estado en la regulación de este sector estratégico para el desarrollo económico, se produjo en diferentes coyunturas. Como resultado de la crisis de 1930, el gobierno brasileño transformó los principios jurídicos que reglamentaban la gestión de la electricidad aplicando un criterio de regulación discrecional; mientras que el estado argentino intervino una década más tarde, nacionalizando las empresas. Mediante la comparación de las trayectorias regulatorias en ambos países, se identifican las divergencias en las políticas eléctricas y su impacto en los sistemas eléctricos en los años de la segunda posguerra.This article compares the evolution of electric utility regulation in Argentina and Brazil between 1890 and 1960. From the installation of electrical systems in the 19th century until the 1930s, electrical utility companies were controlled by the local authorities in both countries. The structure of electrical systems was similar in Argentina and Brazil, however the state regulation of electric utilities took place at different times. As a result of the 1930's crisis, the Brazilian government introduced a new legal approach by applying a discretionary regulation. On the other hand, the Argentinean government intervened one decade later, nationalizing the companies. By comparing both regulatory trajectories, the divergences as well as the effects of each policy on the electrical utility systems in the second postward period, are identified.

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.

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

Nuclear astrophysics: An application of nuclear physics

International Nuclear Information System (INIS)

Fueloep, Z.

2005-01-01

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

Interrelationship between nuclear safety, safeguards and nuclear security

International Nuclear Information System (INIS)

Irie, Kazutomo

2007-01-01

As preventive activities against danger within nuclear systems, three major areas exist; nuclear safety, safeguards and nuclear security. Considering the purpose of these activities, to prevent non-peaceful use is common in nuclear security in general and safeguards. At the same time, measures against sabotage, one of the subcategory in nuclear security, is similar to nuclear safety in aiming at preventing nuclear accidents. When taking into account the insider issues in nuclear security, the distinction between measures against sabotage and nuclear safety becomes ambiguous. Similarly, the distinction between measures against theft, another subcategory in nuclear security, and safeguards also becomes vague. These distinctions are influenced by psychological conditions of members in nuclear systems. Members who have the intention to make nuclear systems dangerous to human society shall be the 'enemy' to nuclear systems and thus be the target for nuclear security. (author)

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

Nuclear experts and nuclear weapons proliferation

International Nuclear Information System (INIS)

Mueller, H.

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)

World Nuclear Association position statement: Safe management of nuclear waste and used nuclear fuel

International Nuclear Information System (INIS)

Saint-Pierre, Sylvain

2006-01-01

This WNA Position Statement summarises the worldwide nuclear industry's record, progress and plans in safely managing nuclear waste and used nuclear fuel. The global industry's safe waste management practices cover the entire nuclear fuel-cycle, from the mining of uranium to the long-term disposal of end products from nuclear power reactors. The Statement's aim is to provide, in clear and accurate terms, the nuclear industry's 'story' on a crucially important subject often clouded by misinformation. Inevitably, each country and each company employs a management strategy appropriate to a specific national and technical context. This Position Statement reflects a confident industry consensus that a common dedication to sound practices throughout the nuclear industry worldwide is continuing to enhance an already robust global record of safe management of nuclear waste and used nuclear fuel. This text focuses solely on modern civil programmes of nuclear-electricity generation. It does not deal with the substantial quantities of waste from military or early civil nuclear programmes. These wastes fall into the category of 'legacy activities' and are generally accepted as a responsibility of national governments. The clean-up of wastes resulting from 'legacy activities' should not be confused with the limited volume of end products that are routinely produced and safely managed by today's nuclear energy industry. On the significant subject of 'Decommissioning of Nuclear Facilities', which is integral to modern civil nuclear power programmes, the WNA will offer a separate Position Statement covering the industry's safe management of nuclear waste in this context. The paper's conclusion is that the safe management of nuclear waste and used nuclear fuel is a widespread, well-demonstrated reality. This strong safety record reflects a high degree of nuclear industry expertise and of industry responsibility toward the well-being of current and future generations. Accumulating

Según la Real Academia Española, el término «líder» significa «persona que dirige u orienta a un grupo, que reconoce su autoridad». Es importante este término ya que es muy ambiguo, porque no reconoce el nivel moral o la empatía que puede ejercer una persona en determinado grupo al reconocerlo como líder, y no solo con la autoridad que este puede ejercer en el mismo, siendo este último concepto algo muy común en el mundo anglosajón, denominándose líder a alguien que tiene un puesto de autoridad, lo cual se puede confundir con lo que conocemos como «jefe».

Demostramos que el antiestrógeno fulvestrant (FUL, ICI182.780 indujo la regresión completa de tumores C4-HD creciendo con MPA. El progestágeno indujo la expresión temprana de CCND1 y MYC en células T47D y este efecto fue revertido al bloquear el REa. En células tratadas con MPA utilizamos ensayos de inmunoprecipitación de la cromatina (ChIP y corroboramos la colocalización nuclear de RP/REa en los mismos sitios de los promotores de CCND1 y MYC. El ICI no afectó la unión de RP a ambas secuencias regulatorias, pero sí inhibió la unión del REa. Confirmamos la interacción nuclear entre REa y RP en muestras de cáncer de mama humano. Los resultados demuestran que la presencia del REa, interactuando con el RP, en promotores de CCND1 y MYC es fundamental para la transcripción génica y la proliferación celular inducida por el progestágeno.

Nuclear power generation and nuclear non-proliferation

International Nuclear Information System (INIS)

Rathjens, G.

1979-01-01

The main points existing between nuclear energy development and nuclear non-proliferation policy are reviewed. The solar energy and other energy will replace for nuclear fission energy in the twenty first century, but it may not occur in the first half, and the structure has to be established to continue the development of nuclear fission technology, including breeder reactor technology. In the near future, it should be encouraged to use advanced thermal reactors if they are economic and operated with safety. Miserable results may be created in the worldwide scale, if a serious accident occurs anywhere or nuclear power reactors are utilized for military object. It is estimated to be possible to develop the ability of manufacturing nuclear weapons within two or three years in the countries where the industry is highly developed so as to generate nuclear power. It is also difficult to take measures so that nuclear power generation does not increase nuclear proliferation problems, and it is necessary to mitigate the motive and to establish the international organization. Concensus exists that as the minimum security action, the storage and transportation of materials, which can be directly utilized for nuclear weapons, should be decided by the international system. The most portions of sensitive nuclear fuel cycle should be put under the international management, as far as possible. This problem is discussed in INFCE. Related to the nuclear nonproliferation, the difference of policy in fuel cycle problems between USA and the other countries, the enrichment of nuclear fuel material, especially the reasons to inhibit the construction of additional enrichment facilities, nuclear fuel reprocessing problems, radioactive waste disposal, plutonium stock and plutonium recycle problems are reviewed.

Nuclear re-think [The case for nuclear energy

International Nuclear Information System (INIS)

Moore, P.

2006-01-01

In the early 1970s, Patrick Moore, a co-founder of Greenpeace, believed that nuclear energy was synonymous with nuclear holocaust. Thirty years on, his views have changed because nuclear energy is the only non-greenhouse-gas-emitting power source that can effectively replace fossil fuels while satisfying the world's increasing demand for energy. Today, 441 nuclear plants operating globally avoid the release of nearly 3 billion tonnes of CO 2 emissions annually-the equivalent of the exhaust from more than 428 million cars. Concerns associated with nuclear energy are discussed including costs of nuclear energy, safety of nuclear plants, radioactive waste management, vulnerability of nuclear plants to terrorist attacks and diversion of nuclear fuel for weaponization. It is concluded that nuclear energy is the best way to produce safe, clean, reliable baseload electricity, and will play a key role in achieving global energy security. With climate change at the top of the international agenda, we must all do our part to encourage a nuclear energy renaissance

Full Text Available La libertad personal es un derecho fundamental, no absoluto, puesto que puede limitarse con sujeción estricta a los requisitos constitucionales y legales. El derecho a la libertad personal puede limitarse por orden de autoridad judicial competente, y para esos efectos, la autoridad judicial competente es el juez con función de control de garantías, el juez de conocimiento o de maneraexcepcional la Fiscalía General de la Nación. La flagrancia es una excepción a esa orden de autoridad judicial competente para limitar la libertad personal, pero en el artículo 28, inciso segundo de la Constitución Política, existe la llamada Detención Preventiva Administrativa, cuyos lineamientos para su aplicación, fueron trazados por la Corte Constitucional, sin que se requiriera orden de autoridad judicial competente para privar de la libertad personal a una persona. Posteriormente, con la vigencia del Sistema Penal de corte Acusatorio, dicha figura fue cuestionada y se tornó dudosa su aplicación conforme los lineamientos trazados por la Corte Constitucional.Posteriormente, la Corte Constitucional retoma el tema de la Detención Preventiva Administrativa, retira del ordenamiento jurídico la interpretación anterior y concluye que la Detención preventiva Administrativa procede siempre que exista orden de captura proferida por una autoridad judicial competente. Posteriormente, la Corte Suprema de Justicia, Sala de Casación Penal, en algunas decisiones de habeas corpus, parece revivir la figura de la Detención Preventiva Administrativa.

Clandestine nuclear trade and the threat of nuclear terrorism

International Nuclear Information System (INIS)

Spector, L.S.

1987-01-01

The nuclear netherworld may ultimately contribute to the danger of nuclear terrorism in at least three ways. First, as national governments exploit this underground market and nuclear weapons spread to additional states, the possibility that terrorists will gain access to them will grow. Such weapons in nuclear threshold countries are likely to be more vulnerable to terrorist seizure than they are in today's more advanced nuclear weapons states. Second, terrorist groups might seek to exploit the nuclear gray market themselves, using the same subterfuges that national governments use. Although in today's nuclear netherworld, subnational groups cannot obtain nuclear arms or nuclear weapons material and cannot hope to build the complex installations needed to produce the latter, they might be able to engage in a form of barter with sympathetic emerging nuclear states (for example, offering raw materials or needed nuclear hardware in return for nuclear weapons material. Finally, there is always the risk that nuclear arms or nuclear weapon materials will someday become available on the nuclear black market. There is evidence indicating that terrorist organizations might well be interested in acquiring such items. Understanding underground nuclear commerce in its current form is essential to prevent such future dangers

The threat of nuclear terrorism: Nuclear weapons or other nuclear explosive devices

International Nuclear Information System (INIS)

Maerli, Morten Bremer

2001-01-01

Full text: Conventional weaponry and tactics are likely to remain the primary terrorist means for a definitive majority of sub-national groups. No non-state actors have ever deployed or used a nuclear device. However, recent developments in international terrorism may point in the direction of future terrorist uses of weapons of mass destruction, including nuclear devices. Some terrorist groups with a high international profile have showed disturbing interests in acquiring nuclear weapon capabilities. As the 'terrorist nuclear weapon standards' are likely to be lower than the strict requirements for traditional state nuclear weapons, technical barriers should not be considered sufficient to avoid future nuclear terrorist violence. Preventing any extremist group from achieving their goals of large-scale nuclear killing is likely best done by preventing the access to fissile materials through state compliances to rigorous standards of Material Protection, Control and Accountability (MPC and A).

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

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

Nuclear power has experienced a major boom in the last few years, primarily because it is a non-CO{sub 2} emitting energy source, it can be produced at competitive costs and it can boost a country's security of supply. there are still two issues to be addressed in relation to the currently used technologies: the degree to which the energy content of nuclear fuel is used, and wastes. A solution to both these aspects would ut nuclear power in the category of sustainable energy. The article provides details on current nuclear plans in the wold, the impact of the Fukushima accident on different countries nuclear plans and the European initiatives for sustainable nuclear energy development.

En el marco globalizado y liberalizado en el que el sector desarrolla su actividad, analiza la disyuntiva inversión del sector Público versus inversión del Sector Privado, estudia la influencia de las instituciones regulatorias en la inversión y pone de manifiesto el delicado momento que atraviesa la citada inversión en estas infraestructuras. Este análisis se completa con un estudio de la evolución de los ingresos y las inversiones de la industria que refleja cuantitativamente la actualidad del sector y confirma el riesgo de deterioro de las redes actuales. Enfrentados a un nuevo ciclo en el despliegue de infraestructuras, se constata que las circunstancias actuales no permiten el decidido empuje que requieren los desarrollos de banda ancha necesarios en la nueva sociedad del conocimiento. En este escenario, los actores del sector han reaccionado introduciendo nuevos mecanismos y donde la innovación, tanto tecnológica como de procesos, juega un papel muy relevante: los actores del sector tecnológico cambian las formas de relacionarse, buscan nuevas y originales fuentes de ingresos y se acercan a los clientes para conseguir suplir, con novedosas estrategias, la falta de inversión en infraestructuras.

Nuclear disarmament and peaceful nuclear technology

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

Redefining interrelationship between nuclear safety, nuclear security and safeguards

Irie, Kazutomo

2011-01-01

Since the beginning of this century, the so-called 3Ss (Nuclear Safety, Nuclear Security and Safeguards) have become major regulatory areas for peaceful uses of nuclear energy. The importance of the 3Ss is now emphasized to countries which are newly introducing nuclear power generation. However, as role models for those newcomers, existing nuclear power countries are also required to strengthen their regulatory infrastructure for the 3Ss. In order to rationalize the allocation of regulatory resources, interrelationship of the 3Ss should be investigated. From the viewpoint of the number of the parties concerned in regulation, nuclear security is peculiar with having 'aggressors' as the third party. From the viewpoint of final goal of regulation, nuclear security in general and safeguards share the goal of preventing non-peaceful uses of nuclear energy, though the goal of anti-sabotage within nuclear security is rather similar to nuclear safety. As often recognized, safeguards are representative of various policy tools for nuclear non-proliferation. Strictly speaking, it is not safeguards as a policy tool but nuclear non-proliferation as a policy purpose that should be parallel to other policy purposes (nuclear safety and nuclear security). That suggests 'SSN' which stands for Safety, Security and Non-proliferation is a better abbreviation rather than 3Ss. Safeguards as a policy tool should be enumerated along with nuclear safety regulation, nuclear security measures and trade controls on nuclear-related items. Trade controls have been playing an important role for nuclear non-proliferation. These policy tools can be called 'SSST' in which Trade controls are also emphasized along with Safety regulation, Security measures and Safeguards. Recently, it becomes quite difficult to clearly demarcate these policy tools. As nuclear security concept is expanding, the denotation of nuclear security measures is also expanding. Nuclear security measures are more and more

This white paper informs the nuclear astrophysics community and funding agencies about the scientific directions and priorities of the field and provides input from this community for the 2015 Nuclear Science Long Range Plan. It summarizes the outcome of the nuclear astrophysics town meeting that was held on August 21 - 23, 2014 in College Station at the campus of Texas A&M University in preparation of the NSAC Nuclear Science Long Range Plan. It also reflects the outcome of an earlier town meeting of the nuclear astrophysics community organized by the Joint Institute for Nuclear Astrophysics (JINA) on October 9 - 10, 2012 Detroit, Michigan, with the purpose of developing a vision for nuclear astrophysics in light of the recent NRC decadal surveys in nuclear physics (NP2010) and astronomy (ASTRO2010). The white paper is furthermore informed by the town meeting of the Association of Research at University Nuclear Accelerators (ARUNA) that took place at the University of Notre Dame on June 12 - 13, 2014. In summary we find that nuclear astrophysics is a modern and vibrant field addressing fundamental science questions at the intersection of nuclear physics and astrophysics. These questions relate to the origin of the elements, the nuclear engines that drive life and death of stars, and the properties of dense matter. A broad range of nuclear accelerator facilities, astronomical observatories, theory efforts, and computational capabilities are needed. With the developments outlined in this white paper, answers to long-standing key questions are well within reach in the coming decade.

BS degree in nuclear engineering or a nuclear option

Williams on, T.G.

1988-01-01

Many nuclear engineering educators are concerned about the health of nuclear engineering academic departments. As part of a review of the BS nuclear engineering degree program at the University of Virginia, the authors surveyed several local utilities with operating nuclear plants about their needs for nuclear engineering graduates. The perception of many of the utility executives about a nuclear engineering degree and about a nuclear option in another engineering curriculum does not agree with the way the authors view these two degrees. The responses to two of the survey questions were of particular interest: (1) does your company have a preference between nuclear engineering graduates and graduates in other fields with a nuclear option? (2) what do you consider to be a minimum level of education in nuclear engineering for a nuclear option in mechanical engineering? All of the four utilities that were surveyed stated a preference for mechanical or electrical engineers with a nuclear option, although two indicated that there are certain jobs for which a nuclear engineering graduate is desired

Quantum nuclear pasta and nuclear symmetry energy

Science.gov (United States)

Fattoyev, F. J.; Horowitz, C. J.; Schuetrumpf, B.

2017-05-01

Complex and exotic nuclear geometries, collectively referred to as "nuclear pasta," are expected to appear naturally in dense nuclear matter found in the crusts of neutron stars and supernovae environments. The pasta geometries depend on the average baryon density, proton fraction, and temperature and are critically important in the determination of many transport properties of matter in supernovae and the crusts of neutron stars. Using a set of self-consistent microscopic nuclear energy density functionals, we present the first results of large scale quantum simulations of pasta phases at baryon densities 0.03 ≤ρ ≤0.10 fm-3 , proton fractions 0.05 ≤Yp≤0.40 , and zero temperature. The full quantum simulations, in particular, allow us to thoroughly investigate the role and impact of the nuclear symmetry energy on pasta configurations. We use the Sky3D code that solves the Skyrme Hartree-Fock equations on a three-dimensional Cartesian grid. For the nuclear interaction we use the state-of-the-art UNEDF1 parametrization, which was introduced to study largely deformed nuclei, hence is suitable for studies of the nuclear pasta. Density dependence of the nuclear symmetry energy is simulated by tuning two purely isovector observables that are insensitive to the current available experimental data. We find that a minimum total number of nucleons A =2000 is necessary to prevent the results from containing spurious shell effects and to minimize finite size effects. We find that a variety of nuclear pasta geometries are present in the neutron star crust, and the result strongly depends on the nuclear symmetry energy. The impact of the nuclear symmetry energy is less pronounced as the proton fractions increase. Quantum nuclear pasta calculations at T =0 MeV are shown to get easily trapped in metastable states, and possible remedies to avoid metastable solutions are discussed.

Two-stage nuclear refrigeration with enhanced nuclear moments

International Nuclear Information System (INIS)

Hunik, R.

1979-01-01

Experiments are described in which an enhanced nuclear system is used as a precoolant for a nuclear demagnetisation stage. The results show the promising advantages of such a system in those circumstances for which a large cooling power is required at extremely low temperatures. A theoretical review of nuclear enhancement at the microscopic level and its macroscopic thermodynamical consequences is given. The experimental equipment for the implementation of the nuclear enhanced refrigeration method is described and the experiments on two-stage nuclear demagnetisation are discussed. With the nuclear enhanced system PrCu 6 the author could precool a nuclear stage of indium in a magnetic field of 6 T down to temperatures below 10 mK; this resulted in temperature below 1 mK after demagnetisation of the indium. It is demonstrated that the interaction energy between the nuclear moments in an enhanced nuclear system can exceed the nuclear dipolar interaction. Several experiments are described on pulsed nuclear magnetic resonance, as utilised for thermometry purposes. It is shown that platinum NMR-thermometry gives very satisfactory results around 1 mK. The results of experiments on nuclear orientation of radioactive nuclei, e.g. the brute force polarisation of 95 NbPt and 60 CoCu, are presented, some of which are of major importance for the thermometry in the milli-Kelvin region.

Safeguards as a policy tool should be enumerated along with nuclear safety regulation, nuclear security measures and trade controls on nuclear-related items. Trade controls have been playing an important role for nuclear non-proliferation. These policy tools can be called “SSST” in which Trade controls are also emphasized along with Safety regulation, Security measures and Safeguards. (author)

Position paper on nuclear proliferation issues preventing nuclear proliferation. A duty for the nuclear community

Energy Technology Data Exchange (ETDEWEB)

Goldschmidt, Pierre; Bonin, Bernard [ENS High Scientific Council, Brussels (Belgium)

2010-06-15

The production of electricity from nuclear power plants is widely seen today as having an increasing role to play in meeting global energy requirements in a sustainable manner. Conscious of the inherently sensitive nature of nuclear technology and materials the ENS-HSC (European Nuclear Society - High Scientific Council) is well aware that a severe safety, security, environmental or proliferation mishap stemming from nuclear energy anywhere in the world would undermine the potential for nuclear energy to contribute to the global energy supply and the minimization of harmful carbon emissions. While the safety of nuclear power plants has continuously improved over the last three decades, the same degree of success cannot be claimed when it comes to the achievements of the international community in stemming the risk of nuclear weapons proliferation. This unfortunate situation is due to both technical and political reasons. The European nuclear industry is committed to the exclusively peaceful use of nuclear energy and to export nuclear facilities and related materials, equipment and technology solely in accordance with relevant national export laws and regulations, Nuclear Suppliers Group guidelines and pertinent United Nations Security Council Resolutions. The ENS-HSC considers that, as a manifestation of their strong commitment to nonproliferation, it is important for the nuclear industry to pay special attention to and promote proliferation-resistant designs and to take IAEA safeguards requirements into account at the design stage. Preventing nuclear proliferation is primarily the responsibility of states but, as major stakeholders, the nuclear industry and scientific community should actively support nuclear disarmament as foreseen in the Non-Proliferation Treaty and measures necessary to strengthen the non-proliferation regime, particularly the international control of the flux of nuclear material and technology.

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.

In Global Center of Excellence Program of The University of Tokyo, Non- Proliferation Study Committee by the members of nuclear industries, electricity utilities, nuclear energy institutes and universities has initiated on October 2008 from the viewpoints of investigating a package of measures for nuclear non-proliferation and bringing up young people who will support the near-future nuclear energy system. One of the non-proliferation issues in the Committee is the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Objective of this treaty is to cease all nuclear weapon test explosions and all other nuclear explosion. This purpose should be contributed effectively to the political stability of the Asian region by continuous efforts to eliminate the nuclear weapons. In the Committee, by extracting several issues related to the CTBT, conception of 'Asia nuclear-test-ban network for nuclear non-proliferation' has been discussed with the aim of the nuclear-weapon security in Asian region, where environmental nuclear-test monitoring data is mainly treated and utilized. In this paper, the conception of the 'network' is presented in detail. (author)

Building world-wide nuclear industry success stories - Safe management of nuclear waste and used nuclear fuel

International Nuclear Information System (INIS)

Saint-Pierre, S.

2005-01-01

Full text: This WNA Position Statement summarizes the worldwide nuclear industry's record, progress and plans in safely managing nuclear waste and used nuclear fuel. The global industry's safe waste management practices cover the entire nuclear fuel-cycle, from the mining of uranium to the long-term disposal of end products from nuclear power reactors. The Statement's aim is to provide, in clear and accurate terms, the nuclear industry's 'story' on a crucially important subject often clouded by misinformation. Inevitably, each country and each company employs a management strategy appropriate to a specific national and technical context. This Position Statement reflects a confident industry consensus that a common dedication to sound practices throughout the nuclear industry worldwide is continuing to enhance an already robust global record of safe management of nuclear waste and used nuclear fuel. This text focuses solely on modern civil programmes of nuclear-electricity generation. It does not deal with the substantial quantities of waste from military or early civil nuclear programmes. These wastes fall into the category of 'legacy activities' and are generally accepted as a responsibility of national governments. The clean-up of wastes resulting from 'legacy activities' should not be confused with the limited volume of end products that are routinely produced and safely managed by today's nuclear energy industry. On the significant subject of 'Decommissioning of Nuclear Facilities', which is integral to modern civil nuclear power programmes, the WNA will offer a separate Position Statement covering the industry's safe management of nuclear waste in this context. The safe management of nuclear waste and used nuclear fuel is a widespread, well-demonstrated reality. This strong safety record reflects a high degree of nuclear industry expertise and of industry responsibility toward the well-being of current and future generations. Accumulating experience and

Anon.

1994-01-01

The United Kingdom Government's Nuclear Review currently underway, addresses whether and in what form nuclear power should continue to be part of the country's power generation capability. This article sets out the response of the Institution of Nuclear Engineers to the Nuclear Review. This pro-nuclear group emphasises the benefits to be gained from diversity of generation in the energy supply industry. The environmentally benign nature of nuclear power is emphasised, in terms of gaseous emissions. The industry's excellent safety record also argues in favour of nuclear power. Finally, as power demand increases globally, a health U.K. nuclear industry could generate British wealth through power exports and via the construction industry. The Institution's view on radioactive waste management is also set out. (UK)

Theoretical studies in nuclear reactions and nuclear structure

International Nuclear Information System (INIS)

1992-05-01

Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. Hadrons in nuclear matter; the structure of hadrons; relativistic nuclear physics and heavy ion dynamics and related processes. The section on hadrons in nuclear matter groups together research items which are aimed at exploring ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. A very interesting result has been the finding that QCD sum rules supply a new insight into the decrease of the nucleon's mass in the nuclear medium. The quark condensate, which characterizes spontaneous chiral symmetry breaking of the late QCD vacuum, decreases in nuclear matter and this is responsible for the decrease of the nucleon's mass. The section on the structure of hadrons contains progress reports on our research aimed at understanding the structure of the nucleon. Widely different approaches are being studied, e.g., lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. A major goal of this type of research is to develop appropriate links between nuclear physics and QCD. The section on relativistic nuclear physics represents our continuing interest in developing an appropriate relativistic framework for nuclear dynamics. A Lorentz-invariant description of the nuclear force suggests a similar decrease of the nucleon's mass in the nuclear medium as has been found from QCD sum rules. Work in progress extends previous successes in elastic scattering to inelastic scattering of protons by nuclei. The section on heavy ion dynamics and related processes reports on research into the e + e - problem and heavy ion dynamics

Leading twist nuclear shadowing, nuclear generalized parton distributions and nuclear DVCS at small x

Energy Technology Data Exchange (ETDEWEB)

Guzey, Vadim; Goeke, Klaus; Siddikov, Marat

2009-01-01

We generalize the leading twist theory of nuclear shadowing and calculate quark and gluon generalized parton distributions (GPDs) of spinless nuclei. We predict very large nuclear shadowing for nuclear GPDs. In the limit of the purely transverse momentum transfer, our nuclear GPDs become impact parameter dependent nuclear parton distributions (PDFs). Nuclear shadowing induces non-trivial correlations between the impact parameter $b$ and the light-cone fraction $x$. We make predictions for the deeply virtual Compton scattering (DVCS) amplitude and the DVCS cross section on $^{208}$Pb at high energies. We calculate the cross section of the Bethe-Heitler (BH) process and address the issue of the extraction of the DVCS signal from the $e A \\to e \\gamma A$ cross section. We find that the $e A \\to e \\gamma A$ differential cross section is dominated by DVCS at the momentum transfer $t$ near the minima of the nuclear form factor. We also find that nuclear shadowing leads

Nuclear forensics

International Nuclear Information System (INIS)

Venugopal, V.

2010-01-01

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

Emerging nuclear energy systems and nuclear weapon proliferation

Gsponer, A.; Sahin, S.; Jasani, B.

1983-01-01

Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

Securing Chinese nuclear power development: further strengthening nuclear security

Zhang Hui

2014-01-01

Chinese President Xi Jinping addresses China's new concept of nuclear security with four 'equal emphasis' at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi's political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China's existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

2004-01-01

Nuclear forensics and nuclear attribution have become increasingly important tools in the fight against illegal trafficking in nuclear and radiological materials. This technical report documents the field of nuclear forensics and nuclear attribution in a comprehensive manner, summarizing tools and procedures that have heretofore been described independently in the scientific literature. This report also provides national policy-makers, decision-makers, and technical managers with guidance for responding to incidents involving the interdiction of nuclear and radiological materials. However, due to the significant capital costs of the equipment and the specialized expertise of the personnel, work in the field of nuclear forensics has been restricted so far to a handful of national and international laboratories. In fact, there are a limited number of specialists who have experience working with interdicted nuclear materials and affiliated evidence. Most of the laboratories that have the requisite equipment, personnel, and experience to perform nuclear forensic analysis are participants in the Nuclear Smuggling International Technical Working Group or ITWG (see Section 1.8). Consequently, there is a need to disseminate information on an appropriate response to incidents of nuclear smuggling, including a comprehensive approach to gathering evidence that meets appropriate legal standards and to developing insights into the source and routes of nuclear and radiological contraband. Appendix A presents a ''Menu of Options'' for other Member States to request assistance from the ITWG Nuclear Forensics Laboratories (INFL) on nuclear forensic cases

A comprehensive nuclear law environment could be a relevant tool to promote greater confidence in the nuclear energy. Romania has had laws in place governing the regulation of nuclear activities since 1974, which remained in force throughout and subsequent to the national constitutional changes. Up to December 1996, the CNCAN activities were based on Law No. 61/1974 for the development of the nuclear activities in Romania and Law No. 61982 on the quality assurance of the nuclear facilities and nuclear power plants. The Nuclear Safety legislation has been enacted in November 1974 (Law No. 61/1974) and it followed as closely as possible (for that time) the US Atomic Energy Act of 1954, as amended subsequently. The Romanian nuclear regulatory body, called National Commission for Nuclear Activities Control (CNCAN) is a governmental organization responsible for the development of the regulatory framework, the control of its implementation and for the licensing of nuclear facilities. An important issue of CNCAN is to provide the correct and reasoning information to the public. The most important topics focused on nuclear activities for the interest of mass media in Romania are: Radioactive waste management; The cost and benefit of nuclear energy compared by conventional energy; The conditions for transportation of radioactive materials; The consequences of a suppositional nuclear accidents; The safety in operation for nuclear installations. The information provided to press and public by regulatory body is clearly and well structured. The target is to clearly explain to mass media and the public should understand very well the difference between the meaning of a nuclear accident, nuclear incident or nuclear event. CNCAN monitories and surveys the operation in safe conditions the nuclear facilities and plants, the protection against nuclear radiation of the professionally exposed personnel, of the population, of the environment and the material goods.

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. Ties, feelings and affective experiences introduce specific guidelines to the future of the police profession, especially for women. This extra love is experienced sometimes as a duty and others as a strategy to capitalize job skills. The analysis of this particular association contributes to the study of meanings and experiences around the complex process of entry of women into the police force; a process that, in addition to demanding energetic adaptations from women police officers, it also brought

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

Australian authorities have been traditionally opposed to nuclear energy. The interdiction to build nuclear power plants in the Australian states without the approval of the federal authority was even officially written in the environment code in 1999. Today coal provides 75% of the electricity needs of Australia. Because of climate warming, things are changing, the Australian government is now considering the possibility of using nuclear energy and a site located in southern Australian has been selected for the disposal of low and intermediate level radioactive wastes. In this context the Australian Nuclear Association (ANA) is developing an ambitious program for the promotion of all the applications of nuclear energy through the organisation of conferences and meetings with various experts of nuclear industry. The aim is to make the public aware of the assets of nuclear energy. (A.C.)

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.

With nuclear power generating 43% of its total electricity production, Switzerland is amongst the states, employing the highest percentage of nuclear electricity. Although, the country has not ratified any of the international Nuclear Liability Conventions, its Nuclear Third Party Liability Act reflects all the principles, underlying those Conventions. The statutory liability of the operator of a Swiss nuclear installation itself being unlimited, the total insurance limit of CHF 770 m. provides the highest private insurance protection worldwide. With the support of its foreign Reinsurance Pools, the capacity for this insurance guarantee has, over more than 40 years, been built up by the Swiss Nuclear Insurance Pool. Apart from Third Party Liability cover, the Pool also provides Property insurance to Swiss nuclear installation operators and reinsurance cover to other nuclear insurers worldwide. (author)

The important role which the IAEA plays in assisting Member States in the preservation and enhancement of nuclear knowledge and in facilitating international collaboration in this area has been recognized by the General Conference of the International Atomic Energy Agency in resolutions GC(46)/RES/11B, GC(47)/RES/10B, GC(48)/RES/13 and GC(50)/RES/13. A continued focus of IAEA activities in managing nuclear knowledge is to support Member States to secure and sustain human resources for the nuclear sector, comprising both the replacement of retiring staff and building of new capacity. The IAEA assists Member States, particularly developing ones, in their efforts to sustain nuclear education and training in all areas of nuclear technology for peaceful purposes, which is a necessary prerequisite for succession planning, in particular through the networking of nuclear education and training, including activities of the World Nuclear University (WNU) and the Asian Network for Education in Nuclear Technology (ANENT). The report on the attached CD-ROM, The World Nuclear University: New Partnership in Nuclear Education, gives an overview of the history of the development of the World Nuclear University and related IAEA activities and contains an analysis and recommendations from the first WNU Summer Institute, held in 2005 in the USA

Emergency response and nuclear risk governance. Nuclear safety at nuclear power plant accidents

International Nuclear Information System (INIS)

Kuhlen, Johannes

2014-01-01

The present study entitled ''Emergency Response and Nuclear Risk Governance: nuclear safety at nuclear power plant accidents'' deals with issues of the protection of the population and the environment against hazardous radiation (the hazards of nuclear energy) and the harmful effects of radioactivity during nuclear power plant accidents. The aim of this study is to contribute to both the identification and remediation of shortcomings and deficits in the management of severe nuclear accidents like those that occurred at Chernobyl in 1986 and at Fukushima in 2011 as well as to the improvement and harmonization of plans and measures taken on an international level in nuclear emergency management. This thesis is divided into a theoretical part and an empirical part. The theoretical part focuses on embedding the subject in a specifically global governance concept, which includes, as far as Nuclear Risk Governance is concerned, the global governance of nuclear risks. Due to their characteristic features the following governance concepts can be assigned to these risks: Nuclear Safety Governance is related to safety, Nuclear Security Governance to security and NonProliferation Governance to safeguards. The subject of investigation of the present study is as a special case of the Nuclear Safety Governance, the Nuclear Emergency governance, which refers to off-site emergency response. The global impact of nuclear accidents and the concepts of security, safety culture and residual risk are contemplated in this context. The findings (accident sequences, their consequences and implications) from the analyses of two reactor accidents prior to Fukushima (Three Mile Iceland in 1979, Chernobyl in 1986) are examined from a historical analytical perspective and the state of the Nuclear Emergency governance and international cooperation aimed at improving nuclear safety after Chernobyl is portrayed by discussing, among other topics, examples of &apos

Nuclear security - New challenge to the safety of nuclear power plants

International Nuclear Information System (INIS)

Li Ganjie

2008-01-01

The safety of nuclear power plants involves two aspects: one is to prevent nuclear accidents resulted from systems and equipments failure or human errors; the other is to refrain nuclear accidents from external intended attack. From this point of view, nuclear security is an organic part of the nuclear safety of power plants since they have basically the same goals and concrete measures with each other. In order to prevent malicious attacks; the concept of physical protection of nuclear facilities has been put forward. In many years, a series of codes and regulations as well as technical standard systems on physical protection had been developed at international level. The United Nations passed No. 1540 resolution as well as 'Convention on the Suppression of Acts of Nuclear terrorism', and revised 'Convention on Physical Protection of Nuclear Materials', which has enhanced a higher level capacity of preparedness by international community to deal with security issues of nuclear facilities. In China, in order to improve the capability of nuclear power plants on preventing and suppressing the external attacks, the Chinese government consecutively developed the related codes and standards as well as technical documents based on the existing laws and regulations, including 'Guide for the Nuclear Security of Nuclear Power Plants' and 'Guide for the Physical Protection of Nuclear Materials', so as to upgrade the legislative requirements for nuclear security in power plants. The government also made greater efforts to support the scientific research and staff training on physical protection, and satisfying the physical protection standards for newly-built nuclear facilities such as large scale nuclear power plants to meet requirement at international level. At the same time old facilities were renovated and the Chinese government established a nuclear emergency preparedness coordination mechanism, developed corresponding emergency preparedness plans, intensified the

2007-01-01

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

In this debate the Government's policy on nuclear power is discussed. Government policy is that nuclear power is the safest and cleanest way of generating electricity and is cheap. Other political parties who do not endorse a nuclear energy policy are considered not to be acting in the people's best interests. The debate ranged over the risks from nuclear power, the UK safety record, safety regulations, and the environmental effects of nuclear power. The Torness nuclear power plant was mentioned specifically. The energy policy of the opposition parties is strongly criticised. The debate lasted just over an hour and is reported verbatim. (UK)

Nuclear power generation and nuclear nonproliferation

International Nuclear Information System (INIS)

Walske, C.

1978-01-01

In the future outlook around year 2000 of nuclear power, thought must be given to fuel reprocessing and plutonium utilization. The adverse utilization of plutonium may be prevented by the means balanced with its economical value. As the method of less cost with lower effect of nonproliferation, combination of fuel reprocessing and fuel fabrication facilities and mixed plutonium/uranium processing are possible. As the method of more cost with higher effect of nonproliferation the maintenance of high radioactivity and inaccessibility of plutonium is conceivable. As for the agreeable methods in 2000, seven principles may be mentioned, such as the dependence upon the agreements among major nations and upon nuclear exporting countries. These are still inadequate, however. What is important is to provide with the sufficient safeguards to countries concerned to negate the need for nuclear weapons. Efforts are then necessary for leading nuclear countries to extend aids to other nuclear-oriented countries. (Mori, K.)

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.

The 1F got into station blackout situation, and fell into reactor core meltdown due to inability of cooling down the reactor, eventually leading to the emission accident of radioactive substances over a wide range into the atmosphere, soil, seawater and the like. Through various media such as newspapers, TVs, and the Internet after the accident, important facilities for safety were explained with illustrations. Some of them included the contents that can suggest the causes that trigger the same accident as the 1F accident. It is an urgent task to strengthen security against the terrorism aimed at nuclear power facilities including nuclear power plants, and its realization is a serious problem in each country. This paper summarized nuclear security issues and solutions including explanation on the circumstances of the threat increase of nuclear terrorism that had begun before the 1F accident. The recent nuclear security summit reaffirmed that nuclear security is the basic responsibility of each country, and also reaffirmed the responsibility and importance of IAEA for international cooperation. This paper explains the definition of nuclear security, threat of terrorism, and the contents of the IAEA Nuclear Security Series (NSS), and points out that NSS is considered as the basis among basis that all the countries should share.

Iran's nuclear program - for power generation or nuclear weapons?

International Nuclear Information System (INIS)

Kippe, Halvor

2008-11-01

This report addresses the development of a nuclear infrastructure in Iran, and assessments are made on the near-term potential this infrastructure might yield of either nuclear power or nuclear arms production. The most significant facilities are treated in a more elaborate fashion, as these are assumed to have key roles in either a true civilian programme, or in the prospect of weapons-grade fissile material production. The future potential capacity for the latter is calculated under certain presumptions, both in the case that Iran focuses its efforts on uranium-based nuclear weapons, and in the case that it should choose the plutonium path to nuclear weapons. All the conclusions and findings in this report are based on technological considerations. This means that social or political assessments have not prevailed, rather the picture of Iran's nuclear programme is drawn through descriptions and assessments of facilities and systems, and their role in the bigger context. Definite conclusions have not been made as to whether Iran's nuclear programme currently is aimed towards nuclear arms or nuclear power. The secrecy surrounding some of the most prominent nuclear sites together with more or less credible allegations of purely weapons-related activities in the past, make it hard not to conclude that Iran until the disclosures in 2002 made as great an effort as it could on its way on developing nuclear weapons covertly. The scope of today's nuclear programme seems, on the other hand, most likely to be in part to help relieve the ever-increasing need for energy, although considerable deficits to this strategy are identified, at the same time as the Iranian people are united in a giant, high-prestige project in defiance of massive international pressure. Adding to this is a much-feared ability to rapidly being able to redirect their nuclear efforts, and develop nuclear arms in perhaps as little as one year. This so-called break-out scenario, where Iran presumably

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

Combating nuclear terrorism in India: preventive nuclear forensic perspectives

International Nuclear Information System (INIS)

Raghav, N.K.; Lad, J.S.; Deshmukh, A.V.; Jagtap, S.S.

2014-01-01

Nuclear terrorism is constant threat to India by many terrorist organization and neighboring country. These organizations are directly or indirectly aided with nuclear material by terrorism supporting country. Such organization has a significant potential source for acquiring nuclear and other radioactive material. Possibility of leakage is widely feared because of the deteriorating law and order condition, great spur of nuclear proliferation after the cold war and disintegration of USSR. Terrorist could gain access to Nuclear and radioactive material and smuggle to India through porous borders. Preventive forensic approach in screening and searching nuclear and radioactive material will play cardinal role to prevent nuclear disaster happening in India. Future plans could be extracted from terrorists through their narco-tests, brain fingerprinting and a data base on this could be prepared, which could later be used to help prevent any attacks. In present paper authors strongly recommend setting up Preventive Forensic Units in India so that any internal or external nuclear attack could be aborted. (author)

Historical civilian nuclear accident based Nuclear Reactor Condition Analyzer

Science.gov (United States)

McCoy, Kaylyn Marie

There are significant challenges to successfully monitoring multiple processes within a nuclear reactor facility. The evidence for this observation can be seen in the historical civilian nuclear incidents that have occurred with similar initiating conditions and sequences of events. Because there is a current lack within the nuclear industry, with regards to the monitoring of internal sensors across multiple processes for patterns of failure, this study has developed a program that is directed at accomplishing that charge through an innovation that monitors these systems simultaneously. The inclusion of digital sensor technology within the nuclear industry has appreciably increased computer systems' capabilities to manipulate sensor signals, thus making the satisfaction of these monitoring challenges possible. One such manipulation to signal data has been explored in this study. The Nuclear Reactor Condition Analyzer (NRCA) program that has been developed for this research, with the assistance of the Nuclear Regulatory Commission's Graduate Fellowship, utilizes one-norm distance and kernel weighting equations to normalize all nuclear reactor parameters under the program's analysis. This normalization allows the program to set more consistent parameter value thresholds for a more simplified approach to analyzing the condition of the nuclear reactor under its scrutiny. The product of this research provides a means for the nuclear industry to implement a safety and monitoring program that can oversee the system parameters of a nuclear power reactor facility, like that of a nuclear power plant.

Nuclear power

Anon.

1980-01-01

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

Full-text: The need for human resource development programmes in nuclear security was underlined at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors Meetings. Successive IAEA Nuclear Security Plans, the most recent of which was agreed by the Board of Governors in September 2009, give high priority to assisting States in establishing educational programmes in nuclear security in order to ensure the sustainability of nuclear security improvements. The current Nuclear Security Plan 1 covering 2010-2013 emphasizes on the importance of considering existing capacities at international, regional and national levels while designing nuclear security academic programmes. In the course of implementing the Plan, the IAEA developed a guide entitled Educational Programme in Nuclear Security (IAEA Nuclear Security Series No. 12) that consists of a model of a MAster of Science (M.Sc.) and a Certificate Programme in Nuclear Security. This guide was aims at assisting universities or other educational institutes to developed academic programmes in nuclear security. Independently, some universities already offered academic programmes covering some areas of nuclear security, while other universities have asked the IAEA to support the implementation of these programmes. In order to better address current and future request for assistance in this area, the IAEA establish a collaboration network-International Nuclear Security Education Network (INSEN), among universities who are providing nuclear security education or who are interested in starting an academic programme/ course(s) in nuclear security. Universiti Kebangsaan Malaysia (UKM) is a first local university became a member of INSEN since the beginning of the establishment. (author)

The separation of nuclear power from nuclear proliferation

International Nuclear Information System (INIS)

Starr, C.

1979-01-01

There exists world wide a strong common desire to limit nuclear weapons proliferation so as to inhibit or remove the threat of nuclear warfare. While this is a primary international political objective, there has also developed a secondary objective to limit any potential contribution to such nuclear weapons proliferation which might arise by the diversion of weapons material from the civilian nuclear power fuel cycle. This secondary objective is the basis of the present US government policy to defer the reprocessing of nuclear fuels anywhere. This policy has been generally recognized as a temporary expedient to provide time for international reexamination of the problems of weapons proliferation associated with nuclear power. A successful development of the proposed combination of the Fast Breeder Reactor and the Civex fuel reprocessing facility would provide an economical nuclear power source for many centuries which inherently separates nuclear power from the issue of weapons material diversion and proliferation. Further, by so doing, it permits great flexibility in international and national planning for nuclear power, as the issues of fuel dependence and terrorist and subnational diversions disappear. In addition, the expansion of the FBR/Civex system would eat into the LWR spent fuel stockpile, diminishing steadily this relatively accessible plutonium source. And finally, a rapid development of the FBR/Civex for the above reasons would substantially reduce the worldwide concern as to the adequacy of uranium ore supply. (Auth.)

Introducing nuclear power into currently non-nuclear states

International Nuclear Information System (INIS)

Claassen, Gert

2007-01-01

As the nuclear renaissance gains momentum, many countries that currently have no nuclear power plants will begin to consider introducing them. It is anticipated that smaller reactors such as the Pebble Bed Modulator Reactor (PBMR) will not only be sold to current nuclear states to also to states where there is currently no nuclear experience. A range of issues would have to be considered for nuclear plants to be solid to non-nuclear states, such as the appropriate regulatory environment, standardization and codes, non-proliferation, security of supply, obtaining experienced merchant operators, appropriate financial structures and education and training. The paper considers nine major issues that need to be addressed by governments and vendors alike. International cooperation by organisations such as the IAEA, financial institutions and international suppliers will be required to ensure that developing countries as well as developed ones share the benefits of the nuclear renaissance. The opportunities that the nuclear industry affords to develop local skills, create job opportunities and to develop local manufacturing industries are among the important reasons that the South African Government has decided to support and fund the development of the Pebble Bed Modular Reactor project. These considerations are included in the paper. (author)

Nuclear measurements

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

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

The NRV (nuclear reactions video) is an open and permanently extended global system of management and graphical representation of nuclear data and video-graphic computer simulation of low energy nuclear dynamics. It consists of a complete and renewed nuclear database and well known theoretical models of low energy nuclear reactions altogether forming the 'low energy nuclear knowledge base'. The NRV solves two main problems: 1) fast and visualized obtaining and processing experimental data on nuclear structure and nuclear reactions; 2) possibility for any inexperienced user to analyze experimental data within reliable commonly used models of nuclear dynamics. The system is based on the realization of the following principal things: the net and code compatibility with the main existing nuclear databases; maximal simplicity in handling: extended menu, friendly graphical interface, hypertext description of the models, and so on; maximal visualization of input data, dynamics of studied processes and final results by means of real three-dimensional images, plots, tables and formulas and a three-dimensional animation.

Nuclear Symbiosis - A Means to Achieve Sustainable Nuclear Growth while Limiting the Spread of Sensitive Nuclear Technology

International Nuclear Information System (INIS)

Shropshire, David

2009-01-01

Global growth of nuclear energy in the 21st century is creating new challenges to limit the spread of nuclear technology without hindering adoption in countries now considering nuclear power. Independent nuclear states desire autonomy over energy choices and seek energy independence. However, this independence comes with high costs for development of new indigenous fuel cycle capabilities. Nuclear supplier states and expert groups have proposed fuel supply assurance mechanisms such as fuel take-back services, international enrichment services and fuel banks in exchange for recipient state concessions on the development of sensitive technologies. Nuclear states are slow to accept any concessions to their rights under the Non-Proliferation Treaty. To date, decisions not to develop indigenous fuel cycle capabilities have been driven primarily by economics. However, additional incentives may be required to offset a nuclear state's perceived loss of energy independence. This paper proposes alternative economic development incentives that could help countries decide to forgo development of sensitive nuclear technologies. The incentives are created through a nuclear-centered industrial complex with 'symbiotic' links to indigenous economic opportunities. This paper also describes a practical tool called the 'Nuclear Materials Exchange' for identifying these opportunities.

Nuclear winter: Global consequences of multiple nuclear explosions

Turco, R.P.; Toon, O.B.; Ackerman, T.P.; Pollack, J.B.; Sagan, C.

1984-01-01

Concern has been raised over the short- and long-term consequences of the dust, smoke, radioactivity, and toxic vapors that would be generated by a nuclear war. The discovery that dense clouds of soil particles may have played a major role in past mass extinctions of life on Earth has encouraged the reconsideration of nuclear war effects. These developments have led the authors to calculate, using new data and improved models, the potential global environmental effects of dust and smoke clouds (henceforth referred to as nuclear dust and smoke) generated in a nuclear war. They neglect the short-term effects of blast, fire, and radiation. Most of the world's population could probably survive the initial nuclear exchange and would inherit the postwar environment. Accordingly, the longer-term and global-scale aftereffects of nuclear war might prove to be as important as the immediate consequences of the war

Choosing nuclear engineering: A survey of nuclear engineering undergraduates

International Nuclear Information System (INIS)

Shillenn, J.K.; Klevans, E.H.

1988-01-01

Maintaining a reliable pool of qualified nuclear engineering graduates depends on the ability of nuclear engineering undergraduate programs to recruit students. With the prospect of declining enrollments in nuclear engineering it is important for nuclear engineering programs to know what factors influence students to choose nuclear engineering as an undergraduate major and why they choose a particular undergraduate program. This type of information can be very important to nuclear engineering programs that develop recruiting strategies. To provide some insight into this area, a questionnaire was designed and given to undergraduate nuclear engineering students at Pennsylvania State University. The purpose of the survey was to provide information on the reasons that students picked nuclear engineering as a career and chose to attend Penn State. The questionnaire was given to 27 students in their junior year during the spring semester of 1987 and again to 35 junior students during the spring semester of 1988. There was little difference except as noted between the two groups on their responses to the questionnaire. A partial listing of the survey results is provided

High-Frequency Dynamic Nuclear Polarization in the Nuclear Rotating Frame

DEFF Research Database (Denmark)

Farrar, C. T.; Hall, D. A.; Gerfen, G. J.

2000-01-01

A proton dynamic nuclear polarization (DNP) NMR signal enhancement (ϵ) close to thermal equilibrium, ϵ = 0.89, has been obtained at high field (B0 = 5 T, νepr = 139.5 GHz) using 15 mM trityl radical in a 40:60 water/glycerol frozen solution at 11 K. The electron-nuclear polarization transfer...... is performed in the nuclear rotating frame with microwave irradiation during a nuclear spin-lock pulse. The growth of the signal enhancement is governed by the rotating frame nuclear spin–lattice relaxation time (T1ρ), which is four orders of magnitude shorter than the nuclear spin–lattice relaxation time (T1n......). Due to the rapid polarization transfer in the nuclear rotating frame the experiment can be recycled at a rate of 1/T1ρ and is not limited by the much slower lab frame nuclear spin–lattice relaxation rate (1/T1n). The increased repetition rate allowed in the nuclear rotating frame provides an effective...

Nuclear waste management, reactor decommisioning, nuclear liability and public attitudes

International Nuclear Information System (INIS)

Green, R.E.

1982-01-01

This paper deals with several issues that are frequently raised by the public in any discussion of nuclear energy, and explores some aspects of public attitudes towards nuclear-related activities. The characteristics of the three types of waste associated with the nuclear fuel cycle, i.e. mine/mill tailings, reactor wastes and nuclear fuel wastes, are defined, and the methods currently being proposed for their safe handling and disposal are outlined. The activities associated with reactor decommissioning are also described, as well as the Canadian approach to nuclear liability. The costs associated with nuclear waste management, reactor decommissioning and nuclear liability are also discussed. Finally, the issue of public attitudes towards nuclear energy is addressed. It is concluded that a simple and comprehensive information program is needed to overcome many of the misconceptions that exist about nuclear energy and to provide the public with a more balanced information base on which to make decisions

New nuclear projects in the world. Sustainable Nuclear Energy

Leon, P. T.

2011-01-01

Nuclear power has experienced a major boom in the last few years, primarily because it is a non-CO 2 emitting energy source, it can be produced at competitive costs and it can boost a country's security of supply. there are still two issues to be addressed in relation to the currently used technologies: the degree to which the energy content of nuclear fuel is used, and wastes. A solution to both these aspects would ut nuclear power in the category of sustainable energy. The article provides details on current nuclear plans in the wold, the impact of the Fukushima accident on different countries nuclear plans and the European initiatives for sustainable nuclear energy development.

Nuclear fuels

International Nuclear Information System (INIS)

Gangwani, Saloni; Chakrabortty, Sumita

2011-01-01

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.

Nuclear weapons modernizations

Energy Technology Data Exchange (ETDEWEB)

Kristensen, Hans M. [Federation of American Scientists, Washington, DC (United States)

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.

Introducing nuclear power into currently non-nuclear states

International Nuclear Information System (INIS)

Gert, Claassen

2007-01-01

As the nuclear renaissance gains momentum, many countries that currently have no nuclear power plants will begin to consider introducing them. It is anticipated that smaller reactors such as the Pebble Bed Modular Reactor (PBMR) will not only be sold to current nuclear states to also to states where there is currently no nuclear experience. A range of issues would have to be considered for nuclear plants to be sold to non-nuclear states, such as the appropriate regulatory environment, standardization and codes, non-proliferation, security of supply, obtaining experienced merchant operators, appropriate financial structures and education and training. The paper considers nine major issues that need to be addressed by governments and vendors alike: 1) political enabling framework, 2) regulatory framework, 3) responsible owner, 4) responsible operator, 5) finance, 6) contact management, 7) fuel supply and waste management framework, 8) training and education, and 9) industrial infrastructure. International cooperation by organisations such as the IAEA, financial institutions and international suppliers will be required to ensure that developing countries as well as developed ones share the benefits of the nuclear renaissance. The opportunities that the nuclear industry affords to develop local skills, create job opportunities and to develop local manufacturing industries are among the important reasons that the South African Government has decided to support and fund the development of the Pebble Bed Modular Reactor project.

Muon nuclear fusion and low temperature nuclear fusion

International Nuclear Information System (INIS)

Nagamine, Kanetada

1990-01-01

Low temperature (or normal temperature) nuclear fusion is one of the phenomena causing nuclear fusion without requiring high temperature. In thermal nuclear fusion, the Coulomb barrier is overcome with the help of thermal energy, but in the low temperature nuclear fusion, the Coulomb barrier is neutralized by the introduction of the particles having larger mass than electrons and negative charges, at this time, if two nuclei can approach to the distance of 10 -13 cm in the neutral state, the occurrence of nuclear fusion reaction is expected. As the mass of the particles is heavier, the neutral region is smaller, and nuclear fusion is easy to occur. The particles to meet this purpose are the electrons within substances and muons. The research on muon nuclear fusion became suddenly active in the latter half of 1970s, the cause of which was the discovery of the fact that the formation of muons occurs resonantly rapidly in D-T and D-D systems. Muons are the unstable elementary particles having the life of 2.2 μs, and they can have positive and negative charges. In the muon catalyzed fusion, the muons with negative charge take part. The principle of the muon catalyzed fusion, its present status and future perspective, and the present status of low temperature nuclear fusion are reported. (K.I.)

Parvoviral nuclear import: bypassing the host nuclear-transport machinery.

Cohen, Sarah; Behzad, Ali R; Carroll, Jeffrey B; Panté, Nelly

The parvovirus Minute virus of mice (MVM) is a small DNA virus that replicates in the nucleus of its host cells. However, very little is known about the mechanisms underlying parvovirus' nuclear import. Recently, it was found that microinjection of MVM into the cytoplasm of Xenopus oocytes causes damage to the nuclear envelope (NE), suggesting that the nuclear-import mechanism of MVM involves disruption of the NE and import through the resulting breaks. Here, fluorescence microscopy and electron microscopy were used to examine the effect of MVM on host-cell nuclear structure during infection of mouse fibroblast cells. It was found that MVM caused dramatic changes in nuclear shape and morphology, alterations of nuclear lamin immunostaining and breaks in the NE of infected cells. Thus, it seems that the unusual nuclear-import mechanism observed in Xenopus oocytes is in fact used by MVM during infection of host cells.

Towards sustainable nuclear energy: Putting nuclear physics to work

Koning, A.J.; Rochman, D.

We have developed a new method to propagate the uncertainties of fundamental nuclear physics models and parameters to the design and performance parameters of future, clean nuclear energy systems. Using Monte Carlo simulation, it is for the first time possible to couple these two fields at the extremes of nuclear science without any loss of information in between. With the help of a large database of nuclear reaction measurements, we have determined the uncertainties of theoretical nuclear reaction models such as the optical, compound nucleus, pre-equilibrium and fission models. A similar assessment is done for the parameters that describe the resolved resonance range. Integrating this into one simulation program enables us to describe all open channels in a nuclear reaction, including a complete handling of uncertainties. Moreover, in one and the same process, values and uncertainties of nuclear reactor parameters are computed. This bypasses all the intermediate steps which have been used so far in nuclear data and reactor physics. Two important results emerge from this work: (a) we are able to quantify the required quality of theoretical nuclear reaction models directly from the reactor design requirements and (b) our method leads to a deviation from the commonly assumed normal distribution for uncertainties of safety related reactor parameters, and this should be taken into account for future nuclear energy development. In particular, calculated k eff distributions show a high-value tail for fast reactor spectra

There are two nuclear power plants (NPP) in operation in China. The Qinshan NPP was the first that was constructed by China's own efforts and went into operation on 1991. The Daya Bay NPP was constructed using foreign funds, technology and went into operation on 1994. Four nuclear power projects with 8 units were initiated during the State Ninth Five-years Plan. The 8 units are expected for commercial operation between 2002 and 2005. China is preparing for the Tenth Five-Year Plan, in which China will develop the nuclear power at a moderate pace. The 13 universities and colleges were offering nuclear science educations. The students from these universities and college can meet the needs of nuclear institutes and enterprises. China National Nuclear Corporation (CNNC) owns the Graduated School of Nuclear Industry and the Nuclear Industry Administrative Cadre College, which will turn into the nuclear training center in future. Besides, CNNC also owns 4 institutions awarding Doctorate and 9 institutes awarding Master Degree. Many programs for education and training carried out by CNNC are presented, such as direct education supported by CNNC's finances, on job training, education for the second bachelor degree, training for senior economic professionals, research course for senior professionals, short time training course and training for license. China trained nuclear personnel by international cooperation with other countries both through multilateral and bilateral cooperation programs. CNNC has established scientific and economic ties with over 40 countries. CNNC has held diversified training for nuclear industry professionals with our own efforts and with the support from the State for many years. Today, the rapid development of nuclear industry needs more professionals. We must make greater efforts to enhance human resources development. Nuclear Safety is very important for nuclear energy development. Nuclear safety is closely related to each person who works in

START II has not yet been ratified by the US or Russian parliaments. Doubts may be raised over whether it will ever be. In the best case there will be more than 20,000 nuclear warheads in the arsenals of these two countries by the year 2003. All five nuclear states consider that nuclear weapons are an essential component of their national defense. It might sound childish but, the whole story is is so often childish: the five powers refuse to break their nuclear toys. They take even all possible measures to maintain and improve them and to ensure the survivability of their arsenals. To prepare for the next arms race..

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

2014-01-01

Nuclear safety accidents directly affect human health but nuclear security incidents indirectly influence human, which demonstrates the reason why security receives less attention. However, it is acknowledged that nuclear terrorism is indeed one of the most dreadful threat humanity faces. As part of strengthening nuclear security as well as nonproliferation to response to the threat, we need a better understanding of the nuclear material which needs to be safe under the objective of nuclear security. In reality, practitioners implement safeguards and physical protection in compliance with the regulation text in domestic legislation. Thus, it is important to specify nuclear material clearly in law for effective implementation. Therefore, the definition of terminology related to nuclear material is explored herein, within the highest-level legislation on the safeguards and physical protection. First the definition in Korean legislation is analyzed. Then, so as to suggest some improvements, other international efforts are examined and some case studies are conducted on other states which have similar level of nuclear technology and industry to Korea. Finally, a draft of definition on nuclear material in perspective of nuclear nonproliferation and security is suggested based on the analysis below. The recommendation showed the draft nuclear material definition in nuclear control. The text will facilitate the understanding of nuclear material in the context of nuclear nonproliferation and security. It might provide appropriate provision for future legislation related to nuclear nonproliferation and security. For effective safeguards and physical protection measures, nuclear material should be presented with in a consistent manner as shown in the case of United Kingdom. It will be much more helpful if further material engineering studies on each nuclear material are produced. Multi-dimensional approach is required for the studies on the degree of efforts to divert

Russian Federal Nuclear Center facilities for Spectroscopy investigation in the field of nuclear spectroscopy are described. Here are discussed basic properties of used radiation sources, facilities and technologies for target material production and manufacture of targets from rare, high-toxic or radioactive materials. Here are also reported basic features of complex detector systems and technologies for manufacture of scintillation detectors with special properties VNIIEF was founded as a weapons laboratory. The development of nuclear and thermonuclear bombs was followed by a wide complex of nuclear-physics investigations. Naturally, data on nuclear-physics properties of active and structure materials being part of nuclear weapons were of greatest interest.At the initial stage of work on the development of nuclear weapons the information on nuclear constants of materials including the most important neutron ones was rather scant. Data published in scientific literature had low exactness and were insecure. Results of measurements sometimes differed greatly by various groups of investigators. At the same time it was clear that, for example, a 1,5-times mistake in the fission cross-section could cause a several times mistake in the choice of uranium or plutonium mass, which is necessary for the bomb development. These circumstances determined importance of the nuclear-physics investigations. Demands on knowledge of process details occurring inside the nuclei conditioned by a problem of developing and improving of nuclear weapons and atomic power are rather limited. However, the further development of nuclear industry has proved a well-known point that this knowledge being accumulated forms a critical mass that leads to an explosive situation in the elaboration both of ideological and technological aspects of these problems. It is the tendency of inside development of nuclear science that has conditioned preparedness of knowledge about intranuclear processes for

The World Nuclear University - A pillar of the nuclear renaissance

2006-01-01

The World Nuclear University was founded with the support of four leading international nuclear institutions - two of them inter-governmental organisations (IAEA and OECD/NEA), the other two bodies serving the industry and its operators (WNA and WANO). Inaugurated in September 2003 on the 50. anniversary of President Eisenhower's Atoms for Peace speech, the WNU started working a year later upon the arrival of the first staff members. Today there is a tremendous disparity in the nuclear industry between the pace of the unfolding nuclear renaissance, which is gathering momentum by the day, and the slower pace at which we are educating a new generation of nuclear scientists and engineers. The WNU aims to be instrumental in creating a network of leading institutions of nuclear learning in order to help fill this gap. The emerging worldwide partnership aims to: - Enhance nuclear education amongst its members, - Establish globally accepted standards in academic and professional qualification, and - Elevate the prestige of the nuclear profession. Prior to the establishment of WNU, many leading educational institutions of nuclear learning had already launched cooperation on a regional basis, as follows (country or region/network): United States/NEDHO (Nuclear Engineering Department Head Organization); Canada/UNENE (University Network of Excellence in Nuclear Engineering in Canada); Asia/ANENT (Asian Network for Education in Nuclear Technology); Europe/ENEN (European Nuclear Education Network); Russia/WNU Russian Branch. Thus the WNU can be seen to a certain extent as a 'network of networks', although it should be stressed that many of the current WNU members did not belong to already existing networks. By creating a global network, the WNU avoids the duplication of efforts and limits the total number of staff required. The WNU does not lose sight of the fact, however, that local problems should be solved locally. Ten Working Groups share between them the activities of the

Nuclear power generation and nuclear fuel

Okajima, Yasujiro

1985-01-01

As of June 30, 1984, in 25 countries, 311 nuclear power plants of about 209 million kW were in operation. In Japan, 27 plants of about 19 million kW were in operation, and Japan ranks fourth in the world. The present state of nuclear power generation and nuclear fuel cycle is explained. The total uranium resources in the free world which can be mined at the cost below $130/kgU are about 3.67 million t, and it was estimated that the demand up to about 2015 would be able to be met. But it is considered also that the demand and supply of uranium in the world may become tight at the end of 1980s. The supply of uranium to Japan is ensured up to about 1995, and the yearly supply of 3000 st U 3 O 8 is expected in the latter half of 1990s. The refining, conversion and enrichment of uranium are described. In Japan, a pilot enrichment plant consisting of 7000 centrifuges has the capacity of about 50 t SWU/year. UO 2 fuel assemblies for LWRs, the working of Zircaloy, the fabrication of fuel assemblies, the quality assurance of nuclear fuel, the behavior of UO 2 fuel, the grading-up of LWRs and nuclear fuel, and the nuclear fuel business in Japan are reported. The reprocessing of spent fuel and plutonium fuel are described. (Kako, I.)

Nuclear fission and nuclear safeguards: Common technologies and challenges

International Nuclear Information System (INIS)

Keepin, G.R.

1989-01-01

Nuclear fission and nuclear safeguards have much in common, including the basic physical phenomena and technologies involved as well as the commitments and challenges posed by expanding nuclear programs in many countries around the world. The unique characteristics of the fission process -- such as prompt and delayed neutron and gamma ray emission -- not only provide the means of sustaining and controlling the fission chain reaction, but also provide unique ''signatures'' that are essential to quantitative measurement and effective safeguarding of key nuclear materials (notably 239 Pu and 235 U) against theft, loss, or diversion. In this paper, we trace briefly the historical emergence of safeguards as an essential component of the expansion of the nuclear enterprise worldwide. We then survey the major categories of passive and active nondestructive assay techniques that are currently in use or under development for rapid, accurate measurement and verification of safe-guarded nuclear materials in the many forms in which they occur throughout the nuclear fuel cycle. 23 refs., 14 figs

This paper aims to introduce the nuclear engineering education at the Department of Nuclear Engineering, Chulalongkon University, Bangkok Thailand. The department has been offering curriculum in nuclear engineering to support the national nuclear power programme since 1970s. It is the oldest established nuclear engineering educational programme in the South East Asia region. Nevertheless, since the nuclear power programme has been postponed several times due to various reasons, the educational programme at the department has been continuously adapted to meet the nation’s needs. Several areas of study have been introduced, including nuclear power engineering, industrial applications of radioisotope, nuclear instrumentation, radioisotope production, radiation processing, environment and safety, nuclear materials, as well as the newly created nuclear security and non-proliferation. With the renewed interest in using nuclear power in Thailand in 2007, the department has been actively assisting both the government and the electric utility in preparing human resources to support the nuclear power programme through various educational and training modules. Realizing the importance of establishing and balancing all 3 aspects of the nuclear 3S (safety, security and safeguard) in Thailand and in the Southeast Asian region. The new curriculum of nuclear security and safeguard programme has been offered since 2013. Since the establishment, the department has produced hundreds of graduates (Diploma, Master’s, and Ph.D. levels) to feed the continuously expanding Thai nuclear industry. The full paper will provide detailed information of the curriculum, the challenges and obstacles that the department has encountered, as well as the national and international linkages which have been established over the years.

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.

Nuclear security culture in comparison with nuclear safety culture. Resemblances and differences

International Nuclear Information System (INIS)

Kawata, Norio

2015-01-01

Since the terrorist attacks on the U.S. on September 11th, 2001, Nuclear Security has been focused on and treated as a global issue in the international community and it has also been discussed as a real and serious threat to nuclear power plants in the world since 'The Great East Japan Earthquake' in March, 2011. The International Atomic Energy Agency (IAEA) issued a document including Nuclear Security Recommendations (INFCIRC/225/Rev.5) (NSS 13) in the Nuclear Security Series and emphasized the necessity of fostering Nuclear Security Culture. Nuclear Security Culture has been frequently discussed at various kinds of seminars and events. Since the officials in charge of Nuclear Security are familiar with the area of Nuclear Safety, the relationships between Nuclear Safety Culture and Nuclear Security Culture have been the point in controversy. This paper clarifies relevance between Nuclear Safety and Security, considers resemblances and differences of their concepts and lessons learned for each culture from nuclear power plant accidents, and promotes deeper understanding of Nuclear Safety and Nuclear Security Culture.

Alekseev, P.; Dudnikov, A.; Subbotin, S.

2003-01-01

Nuclear Energy for New Europe - what does it mean? New Europe - it means in first order joined Europe. And it is quite clear that also efforts in nuclear energy must be joined. What can be proposed as a target of joint efforts. Improvement of existing plants, technologies, materials? - Certainly, but it is performed already by designers and industry themselves. There exists a problem, which each state using nuclear energy faces alone. It is nuclear waste problem. Nowadays nuclear waste problem is not completely solved in any country. It seems reasonable for joining Europe to join efforts in solving this problem. A satisfactory solution would reduce a risk connected with nuclear waste. In addition to final disposal problem solution it is necessary to reduce total amount of nuclear waste, that means: reducing the rates of accumulation of long-lived dangerous radionuclides; reducing the existing amounts of these radionuclides by transmutation. These conditions can be satisfied in reasonable time by burning of minor actinides and, if possible, by transmutation of long-lived fission products. However we can use this strategy effectively if we will design and construct nuclear energy as a system of which components are united by nuclear fuel cycle as a system-forming factor. The existing structures and approaches may become insufficient for new Europe. Therefore among the initial steps in considering nuclear waste problem must be considering possible promising fuel cycles for European nuclear energy. So, does new Europe need new nuclear energy? It seems, yes. (author)

Nuclear Symbiosis - A Means to Achieve Sustainable Nuclear Growth While Limiting the Spread of Sensitive Nuclear Technology

International Nuclear Information System (INIS)

Shropshire, David

2009-01-01

Global growth of nuclear energy in the 21. century is creating new challenges to limit the spread of nuclear technology without hindering adoption in countries now considering nuclear power. Independent nuclear states desire autonomy over energy choices and seek energy independence. However, this independence comes with high costs for development of new indigenous fuel cycle capabilities. Nuclear supplier states and expert groups have proposed fuel supply assurance mechanisms such as fuel take-back services, international enrichment services and fuel banks in exchange for recipient state concessions on the development of sensitive technologies. Recipient states are slow to accept any concessions to their rights under the Non Proliferation Treaty. To date, decisions to not develop indigenous fuel enrichment capabilities have been driven by economics. However, additional incentives may be required in the future to offset the user state's perceived loss of energy independence. In order for a country to forgo development of sensitive nuclear capabilities, the basis for an equitable economic tradeoff must be established. This paper proposes that the nuclear trade-off can be made through a combination of fuel supply assurances, leveraging work by the United Nations and International Atomic Energy Agency on sustainable nuclear development, and use of 'nuclear symbiosis'. The primary focus of this paper is on how nuclear symbiosis could be used to achieve a user-state's desired economic, energy, and infrastructure development end states. The desired result from this 'symbiosis' is a nuclear-centered industrial complex that creates new economic opportunities through infrastructure improvements, human resource skills development and the development of new sustainable industries. This paper also describes the Nuclear Materials Exchange (NME) as a practical tool for performing nuclear symbiosis. The NME can be used to define existing and new international nuclear resources and

Nuclear violence

Mullen, R.K.

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 energy

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)

Theoretical studies in nuclear reactions and nuclear structure. Progress report

Energy Technology Data Exchange (ETDEWEB)

1992-05-01

Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. Hadrons in nuclear matter; the structure of hadrons; relativistic nuclear physics and heavy ion dynamics and related processes. The section on hadrons in nuclear matter groups together research items which are aimed at exploring ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. A very interesting result has been the finding that QCD sum rules supply a new insight into the decrease of the nucleon`s mass in the nuclear medium. The quark condensate, which characterizes spontaneous chiral symmetry breaking of the late QCD vacuum, decreases in nuclear matter and this is responsible for the decrease of the nucleon`s mass. The section on the structure of hadrons contains progress reports on our research aimed at understanding the structure of the nucleon. Widely different approaches are being studied, e.g., lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. A major goal of this type of research is to develop appropriate links between nuclear physics and QCD. The section on relativistic nuclear physics represents our continuing interest in developing an appropriate relativistic framework for nuclear dynamics. A Lorentz-invariant description of the nuclear force suggests a similar decrease of the nucleon`s mass in the nuclear medium as has been found from QCD sum rules. Work in progress extends previous successes in elastic scattering to inelastic scattering of protons by nuclei. The section on heavy ion dynamics and related processes reports on research into the e{sup +}e{sup {minus}} problem and heavy ion dynamics.

With the development of nuclear use for peaceful purposes and the intensification of international cooperation in the field of nuclear energy, many countries attach more and more importance to legal risks of nuclear liability, and the companies in nuclear industry also enhance research on restrictive articles of nuclear liability in their international businesses. However, because China has neither signed any international convention on civil liability for nuclear damage nor adopted any law on atomic energy and on compensation for nuclear damage, many impediments often occur in international cooperation and trade. This essay is trying to outline the status and structure of international nuclear liability, analyze nuclear liabilities in international procurement for nuclear operating companies and respective solutions.

The objective of this study is to examine factors and prospects for a resumption in growth of nuclear power in the United States over the next decade. The focus of analysis on the likelihood that current efforts in the United States to develop improved and safer nuclear power reactors will provide a sound technical basis for improved acceptance of nuclear power, and contribute to a social/political climate more conducive to a resumption of nuclear power growth. The acceptability of nuclear power and advanced reactors to five social/political sectors in the U.S. is examined. Three sectors highly relevant to the prospects for a restart of nuclear power plant construction are the financial sector involved in financing nuclear power plant construction, the federal nuclear regulatory sector, and the national political sector. For this analysis, the general public are divided into two groups: those who are knowledgeable about and involved in nuclear power issues, the involved public, and the much larger body of the general public that is relatively uninvolved in the controversy over nuclear power

The Nuclear Technology Test Center established the Nuclear Safety Analysis Office to execute newly the works concerning nuclear safety analysis in addition to the works related to the proving tests of nuclear machinery and equipments. The regulations for the Nuclear Safety Analysis Office concerning its organization, business and others were specially decided, and it started the business formally in August, 1980. It is a most important subject to secure the safety of nuclear facilities in nuclear fuel cycle as the premise of developing atomic energy. In Japan, the strict regulation of safety is executed by the government at each stage of the installation, construction, operation and maintenance of nuclear facilities, based on the responsibility for the security of installers themselves. The Nuclear Safety Analysis Office was established as the special organ to help the safety examination related to the installation of nuclear power stations and others by the government. It improves and puts in order the safety analysis codes required for the cross checking in the safety examination, and carries out safety analysis calculation. It is operated by the cooperation of the Science and Technology Agency and the Agency of Natural Resources and Energy. The purpose of establishment, the operation and the business of the Nuclear Safety Analysis Office, the plan of improving and putting in order of analysis codes, and the state of the similar organs in foreign countries are described.

An authoritative textbook and up-to-date professional's guide to basic and advanced principles and practices Nuclear reactors now account for a significant portion of the electrical power generated worldwide. At the same time, the past few decades have seen an ever-increasing number of industrial, medical, military, and research applications for nuclear reactors. Nuclear reactor physics is the core discipline of nuclear engineering, and as the first comprehensive textbook and reference on basic and advanced nuclear reactor physics to appear in a quarter century, this book fills a large gap in the professional literature. Nuclear Reactor Physics is a textbook for students new to the subject, for others who need a basic understanding of how nuclear reactors work, as well as for those who are, or wish to become, specialists in nuclear reactor physics and reactor physics computations. It is also a valuable resource for engineers responsible for the operation of nuclear reactors. Dr. Weston Stacey begins with clear presentations of the basic physical principles, nuclear data, and computational methodology needed to understand both the static and dynamic behaviors of nuclear reactors. This is followed by in-depth discussions of advanced concepts, including extensive treatment of neutron transport computational methods. As an aid to comprehension and quick mastery of computational skills, he provides numerous examples illustrating step-by-step procedures for performing the calculations described and chapter-end problems. Nuclear Reactor Physics is a useful textbook and working reference. It is an excellent self-teaching guide for research scientists, engineers, and technicians involved in industrial, research, and military applications of nuclear reactors, as well as government regulators who wish to increase their understanding of nuclear reactors.

Does nuclear power lead to nuclear weapons

International Nuclear Information System (INIS)

Prawitz, J.

1977-01-01

It is pointed out that 'reactor grade' plutonium usually contains about 30 % Pu240 and is unsuitable for weapons. While it is possible to obtain an explosion, it is more difficult to initiate one and its effect, which will be considerably less than with bomb grade plutonium, is difficult to predict. The critical mass will be larger and more cooling required. The proliferation problem is then discussed and the four aspects, vertical, horizontal, sub-national and revolutionary, mentioned. In connection with nuclear power it is the second and third aspects which are of interest. In discussing the possibility of terrorist groups obtaining plutonium, a study by the Swedish Defence Research Institute is quoted as estimating that 10-20 qualified specialists and several years secret preparation would be necessary to make a nuclear weapon. Other authors, e.g. Ted Taylor, have maintained that it would be much easier, but examples of 'student designs' are primitive and unlikely to detonate. Even so, it is emphasised that safeguards and physical security are necessary. Horizontal proliferation is a more real problem and the NPT and IAEA safeguards are discussed in this connection. In conclusion the question of whether the proliferation of nuclear weapons via nuclear power can be prevented cannot be answered with a clear yes or no. Certain states may use nuclear weapon potential as a bargaining factor. However the decision to acquire nuclear weapons is political and while a nuclear power industry would be of help, it would not be decisively so. (JIW)

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)

Nuclear questions

Energy Technology Data Exchange (ETDEWEB)

Durrani, M. [Physics World (United Kingdom)

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

Charge symmetry breaking nuclear forces and the properties of nuclear matter

International Nuclear Information System (INIS)

Haensel, P.

1977-01-01

The charge symmetry breaking (CSB) component of the nuclear forces yields the charge asymmetric term Esub(a)(N-Z)/A in the nuclear binding energy of nuclear matter. Calculation performed with several models of the CSB nuclear forces, and accounting for the strong short-range two-body correlations, gives Esub(a) approximately -0.2 MeV at the normal nuclear density. The charge asymmetry of the effective nucleon-nucleon interaction is determined primarily by the CSB nuclear forces at the neutron excess, observed in finite nuclei. The exclusion principle and dispersion (self-consistency) effects of the nuclear medium decrease this charge asymmetry. (author)

Nuclear disarmament verification

International Nuclear Information System (INIS)

DeVolpi, A.

1993-01-01

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

On China's Nuclear Doctrine

Directory of Open Access Journals (Sweden)

Xia Liping

2015-12-01

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 World Nuclear University - A pillar of the nuclear renaissance

Energy Technology Data Exchange (ETDEWEB)

Nigon, Jean-Louis [World Nuclear University Working Groups, Carlton House, 22a St. James' s Square, London SW1Y 4JH (United Kingdom)

2006-07-01

The World Nuclear University was founded with the support of four leading international nuclear institutions - two of them inter-governmental organisations (IAEA and OECD/NEA), the other two bodies serving the industry and its operators (WNA and WANO). Inaugurated in September 2003 on the 50. anniversary of President Eisenhower's Atoms for Peace speech, the WNU started working a year later upon the arrival of the first staff members. Today there is a tremendous disparity in the nuclear industry between the pace of the unfolding nuclear renaissance, which is gathering momentum by the day, and the slower pace at which we are educating a new generation of nuclear scientists and engineers. The WNU aims to be instrumental in creating a network of leading institutions of nuclear learning in order to help fill this gap. The emerging worldwide partnership aims to: - Enhance nuclear education amongst its members, - Establish globally accepted standards in academic and professional qualification, and - Elevate the prestige of the nuclear profession. Prior to the establishment of WNU, many leading educational institutions of nuclear learning had already launched cooperation on a regional basis, as follows (country or region/network): United States/NEDHO (Nuclear Engineering Department Head Organization); Canada/UNENE (University Network of Excellence in Nuclear Engineering in Canada); Asia/ANENT (Asian Network for Education in Nuclear Technology); Europe/ENEN (European Nuclear Education Network); Russia/WNU Russian Branch. Thus the WNU can be seen to a certain extent as a 'network of networks', although it should be stressed that many of the current WNU members did not belong to already existing networks. By creating a global network, the WNU avoids the duplication of efforts and limits the total number of staff required. The WNU does not lose sight of the fact, however, that local problems should be solved locally. Ten Working Groups share between them the

Stencel, S.

1978-01-01

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

Nuclear forensic is an emerging and highly specialized discipline which deals with nuclear investigation and analysis of nuclear or radiological/radioactive materials. Nuclear Forensic analysis includes various methodology and analytical methods along with morphology, physical, chemical, elemental and isotopic analysis to characterize and develop nuclear database for the identification of unknown nuclear or radiological/radioactive material. The origin, source history, pathway and attribution of unknown radioactive/nuclear material is possible with certainty through Nuclear Forensics. Establishment of Nuclear Forensic Laboratory and development of expertise for nuclear investigation under one roof by developing the nuclear data base and laboratory network is need of the hour to ably address the problems of all the law enforcement and nuclear agencies. The present study provides insight in Nuclear Forensics and focuses on an urgent need for a comprehensive plan to set up Nuclear Forensic Laboratory across India. (author)

Efficacy of nuclear forensics

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

The main concern of Pugwash, with very good reason, is nuclear disarmament, but a negative attitude towards nuclear energy is not only futile, but counterproductive as it misses opportunities to appropriately influence its development. Since nuclear energy cannot be abandoned for ecological (decrease in greenhouse gases emission) and economic reasons as a long term energy source, then efforts should be devoted to make it safe from proliferation, which is possible from scientific and technological point of view

2012-01-01

Based on the design standards for the safety of nuclear and radiation in nuclear power plants, the three accidents in the history of nuclear power are analyzed. And the main factors for these accidents are found out, that is, human factors and unpredicted natural calamity. By combining the design and operation parameters of domestic nuclear plants, the same accidents are studied and some necessary preventive schemes are put forward. In the security operation technology of domestic nuclear power plants nowadays, accidents caused by human factors can by prevented completely. But the safety standards have to be reconsidered for the unpredicted neutral disasters. How to reduce the hazard of nuclear radiation and leakage to the level that can be accepted by the government and public when accidents occur under extreme conditions during construction and operation of nuclear power plants must be considered adequately.

Matsuo, Yuji

2010-01-01

As several countries in the east-Asia and middle-east area have been taking an increasing interest in the deployment of nuclear power generation, Japan's nuclear industries have promoted international business activities including the success in the bid of second nuclear power plants in Vietnam. While there are plans for more than thirty of new reactors in the US, the lifetime extension of existing aged reactors, development of non-existing natural gas and trend of greenhouse gases reduction measures have dampened these plans and probably most of new units will not start construction by 2030. This article reviewed the details of US's new nuclear power introduction, trend of recent government's policies, future perspective of nuclear power construction and business trend of Japan's nuclear industries. Japan's industries should be flexible regarding nuclear power as one option to realize low-carbon society. (T. Tanaka)

Nuclear famine: The indirect effects of nuclear war

International Nuclear Information System (INIS)

Harwell, M.A.; Harwell, C.C.

1986-01-01

The indirect effects of a nuclear war, especially as mediated by disruption in food availability, could be much more extensive than the direct effects. Furthermore, this risk is especially severe for noncombatant countries - for the 4 billion or so humans expected to survive the immediate period after a nuclear war relatively physically unharmed. Thus, a fundamentally different picture of the post-nuclear-war world results, where a large-scale nuclear war between the United States and the Soviet Union would probably result in more eventual fatalities in India than in the United States and the Soviet Union combined, and more people would die on the African continent than in all of Europe. Rather than reflecting images of Hiroshima and Nagasaki, a modern nuclear war would, for most of the people of the world, much more resemble current images of Ethiopia and the Sudan

The Nuclear Security Enterprise, managed by the National Nuclear Security Administration - a semiautonomous agency within the Department of Energy - has been associated with numerous assessments with respect to the estimating, management capabilities, and practices pertaining to nuclear weapon modernization efforts. This report identifies challenges in estimating and analyzing the Nuclear Security Enterprise through an analysis of analogous timeframe conditions utilizing two types of nuclear weapon data - (1) a measure of effort and (2) a function of time. The analysis of analogous timeframe conditions that utilizes only two types of nuclear weapon data yields four summary observations that estimators and analysts of the Nuclear Security Enterprise will find useful.

A three-dimensional nuclear chart is constructed with toy blocks for usage of outreach activity related on nuclear physics and atomic energy. The height of each block represents quantities like atomic mass per nucleon, the total half-life, etc. The bulk properties of the nuclei can be easily understood by using these charts. Explanations for the energy generation of nuclear fusion and fission are visually given. In addition, we newly set another chart with blocks of fission fragment mass distribution from U-235 + a thermal neutron. As an example, the origin of abundances of rather radioactive isotopes like Sr-90 and Cs-137 is explained which created in nuclear reactor and also distributed in the eastern side of Fukushima prefecture due to the accident of Fukushima-Daiichi Nuclear Power Plant. Using our charts, lectures entitled 'Alchemy of the Universe' were delivered to high schools and public places. (author)

Nuclear legislation: analytical study. Regulatory and institutional framework for nuclear activities

International Nuclear Information System (INIS)

2001-01-01

Australia' s basic legislation in the nuclear field consists in five Acts passed by the Federal Parliament. These Acts are as follow: the South Pacific nuclear free zone treaty Act; the nuclear non-proliferation act; the Australian nuclear science and technology organisation act; the Australian nuclear science and technology organisation amendment act; the radiation protection and nuclear safety act. The two first Acts were prompted by the need for domestic legislation to implement Australia 's international obligations. The third arose from a long-standing recognition that the Atomic energy Act was inappropriate as the legislative basis for the activities of Australia 's national nuclear organisation. For its part the fourth Act introduced some necessary changes into the Australian nuclear science and technology organisation Act. Finally, the fifth act establishes a regime to regulate the operation of nuclear installations and the management of radiation sources, where the activities are undertaken by Commonwealth entities. Each of these Acts is discussed in more details in this work. (N.C.)

In defiance of nuclear deterrence: anti-nuclear New Zealand after two decades.

Science.gov (United States)

Reitzig, Andreas

2006-01-01

In 1984, nuclear-armed and nuclear-powered vessels were banned from New Zealand to express the country's rejection of the nuclear deterrence concept. This led to a disagreement with the United States. Today, the ban on nuclear-powered ships is the only element of the nuclear-free legislation that still strains US-New Zealand relations. This article presents the reasons for the ban on nuclear-powered ships, which include scientific safety concerns, a symbolic rejection of the nuclear deterrence posture, and patriotic factors such as a nuclear-free national identity. The military and economic consequences of the ban are also examined. Since the ban on nuclear-powered vessels appears to be neither widely known abroad nor commonly recognised as a supportive disarmament measure outside New Zealand, it is concluded that whatever the future of this ban will be, New Zealand's anti-nuclear image will remain known internationally through the ban on nuclear arms.

Nuclear Materials Diversion Safety and the Long-term Future of Nuclear Energy

International Nuclear Information System (INIS)

Knapp, V.

2002-01-01

Primarily due to irresponsible cold war politics of nuclear weapon countries nuclear proliferation situation is little short of getting out of control. In addition to five nominal nuclear weapon countries there are at present at least three more nuclear weapon countries and several countries with nuclear weapon potential. Non-proliferation treaty (NPT), signed in 1970, has been recognized by most non-nuclear weapon countries as unjust and ineffective. After the initial, deliberate, nuclear weapon developments of five nominal nuclear weapon countries, subsequent paths to nuclear weapons have been preceded by nominal peaceful use of nuclear energy. Uranium enrichment installations as well as reprocessing installations in non-nuclear weapon countries are the weakest spots of fuel cycle for diversion of nuclear materials either by governments or by illicit groups. An energy scenario, which would, by the end of century, replace the large part of fossil fuels use through extension of present nuclear practices, would mean very large increase in a number of such installations, with corresponding increase of the probability of diversion of nuclear materials. Such future is not acceptable from the point of view of proliferation safety. Recent events make it clear, that it cannot be accepted from the requirements of nuclear terrorism safety either. Nuclear community should put it clearly to their respective governments that the time has come to put general interest before the supposed national interest, by placing all enrichment and reprocessing installations under full international control. Such internationalization has a chance to be accepted by non-nuclear weapon countries, only in case should it apply to nuclear weapon countries as well, without exception. Recent terrorist acts, however horrible they were, are child,s play compared with possible acts of nuclear terrorism. Nuclear energy can be made proliferation safe and diversion of nuclear materials safe, and provide

Nuclear power

King, P.

1990-01-01

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)

Nuclear chemistry research for the safe disposal of nuclear waste

Fanghaenel, Thomas

2011-01-01

The safe disposal of high-level nuclear waste and spent nuclear fuel is of key importance for the future sustainable development of nuclear energy. Concepts foresee the isolation of the nuclear waste in deep geological formations. The long-term radiotoxicity of nuclear waste is dominated by plutonium and the minor actinides. Hence it is essential for the performance assessment of a nuclear waste disposal to understand the chemical behaviour of actinides in a repository system. The aqueous chemistry and thermodynamics of actinides is rather complex in particular due to their very rich redox chemistry. Recent results of our detailed study of the Plutonium and Neptunium redox - and complexation behaviour are presented and discussed. (author)
