The phase A of probabilistic safety study of Angra I nuclear power plant is presented, to be used by CNEN and FURNAS Centrais Eletricas S.A. as standard model in operational and safety analysis. The methodology applied is a modernization of WASH 1400/2.11/ study. Angra I safety systems are described. The selection and qualification of initiating sequence accident events which can damage the reactor core are done. The accident scenes are developed using the method of event trees. The reactor in subcritical condition (pressure, fuel temperature within limits and controlled level of reactor vessel) is studied during 24 hours. The uncertainness in failure probabilities of systems and in the determination of sequence frequencies for core danification are evaluated. Total frequency of sequences which cause the fusion of reactor core are presented. (M.C.K.) [pt

A digital simulation of a pressurizer in a PWR nuclear power plant

International Nuclear Information System (INIS)

Sato, E.F.

1980-11-01

A model for pressurizer digital simulation of a PWR nuclear power plant during transients, considering all pressurizer control features, is presented. The pressurizer is divided into two regions separated by a water-vapor interface and non-equilibrium conditions are considered. The particular thermodynamic process followed during insurge and outsurges is determined at each instant of analysis without any previous assumption. The pressure behavior is defined by an explicit equation in any of four possible pressurizer thermodynamic conditions. Thermodynamic properties of steam and water are computed by ASME subroutines and the mathematical formulation presented in this study was programed in FORTRAN IV for a Burroughs-6700 digital computer system. This program was employed to simulate the Shippingport Atomic Power Station and Almirante Alvaro Alberto Nuclear Power Plant - Unit 1 pressurizers. The test results compared with experimental or vendor data show the validity of this analysis method. (Author) [pt

Actually, Brazil has two operating Nuclear Power Plants and a third one under construction, all at Central Nuclear Almirante Alvaro Alberto - CNAAA. To comply with regulatory aspects the power plants operator, Eletronuclear, must present to Brazilian Nuclear Regulatory Agency, CNEN, a decommissioning plan. Brazilian experience with decommissioning is limited because none of any nuclear reactor at the country was decommissioned. In literature, decommissioning process is well described despite few nuclear power reactors have been decommissioned around the world. Some different approach is desirable for multiple reactors sites, case of CNAAA site. During the decommissioning, a great amount of wastes will be produced and have to be properly managed. Particularly, the construction of Auxiliary Services on the site could be a good choice due to the possibility of reducing costs. The present work intends to present to the Eletronuclear some aspects of the decommissioning concept and decommissioning management, storage and disposal de wastes, based on the available literature, regulatory standards of CNEN and international experience as well as to suggest some solutions to be implemented at CNAAA site before starts the decommissioning project in order to maximize the benefits.

Spent nuclear fuel storage - Basic concept

International Nuclear Information System (INIS)

Krempel, Ascanio; Santos, Cicero D. Pacifici dos; Sato, Heitor Hitoshi; Magalhaes, Leonardo de

2009-01-01

According to the procedures adopted in others countries in the world, the spent nuclear fuel elements burned to produce electrical energy in the Brazilian Nuclear Power Plant of Angra do Reis, Central Nuclear Almirante Alvaro Alberto - CNAAA will be stored for a long time. Such procedure will allow the next generation to decide how they will handle those materials. In the future, the reprocessing of the nuclear fuel assemblies could be a good solution in order to have additional energy resource and also to decrease the volume of discarded materials. This decision will be done in the future according to the new studies and investigations that are being studied around the world. The present proposal to handle the nuclear spent fuel is to storage it for a long period of time, under institutional control. Therefore, the aim of this paper is to introduce a proposal of a basic concept of spent fuel storage, which involves the construction of a new storage building at site, in order to increase the present storage capacity of spent fuel assemblies in CNAAA installation; the concept of the spent fuel transportation casks that will transfer the spent fuel assemblies from the power plants to the Spent Fuel Complementary Storage Building and later on from this building to the Long Term Intermediate Storage of Spent Fuel; the concept of the spent fuel canister and finally the basic concept of the spent fuel long term storage.

The goal of this paper is to evaluate the environmental monitoring around the Almirante Alvaro Alberto Nuclear Power Station after the beginning the operation of Unit II, in July 2000. The Environmental Monitoring Laboratory collects several environmental samples and analyses them radiometrically to determine the presence of artificial radionuclides. In the Environmental Monitoring Laboratory, the samples are prepared and analysed following international procedures and the activities of the detectable radionuclides are obtained by gamma spectrometry. The Environmental Monitoring Laboratory analyses tritium in sea water as well. This paper will describe only the monitoring of the marine samples and the results of the measurements are compared with those obtained in pre-operational time of Angra 1 (1978 - 1982), Angra 2 (1996 - 2000) and those obtained in operational time of the units until 2008. The results show that, since 1982 until now, there is no impact on marine environment caused by the operation of Angra 1 and Angra 2. (author)

Analysis of the loss of coolant accident due to the faiture in the open position of two pressurizer relief valves, for Angra-1 nuclear power plant

International Nuclear Information System (INIS)

Freire, C.F.

1981-06-01

A study of the modeling techniques adequate for simulating the loss of coolant accident caused by stuck open pressurizer relief valves, using the RELAP4-MOD5 code, is performed and the model developed is applied to the analysis of this kind of accident for the Central Nuclear Almirante Alvaro Alberto Unit (Angra 1). The thermal hydraulic behavior of the reactor cooling system, when subjected to a loss of main feedwater followed by the failure in the open position of two pressurizer relief valves, is determined. The relief valves are assumed to fail in the totally open position, delivering the maximum massflow through the discharge line. The RELAP4-MOD5 code is shown to be adequate for this kind of analysis, and the detailed prediction of the thermal hydraulic behavior of the Reactor Coolant System is thus possible. The eficiency of the emergency core cooling system of Angra 1 is demonstrated, the fuel elements remaining covered by the coolant during all the accident, and the peak clad temperatures are kept within design limites, ensuring the integrity of the core.

This work aims to create a model and a prototype, using the Python language, which with the application of an Expert System uses production rules to analyze the data obtained in real time from the plant and help the operator to identify the occurrence of transients / accidents. In the event of a transient, the program alerts the operator and indicates which section of the Operation Manual should be consulted to bring the plant back to its normal state. The generic structure used to represent the knowledge of the Expert System was a Fault Tree and the data obtained from the plant was done through intelligent acquisition agents that transform the data obtained from the plant into Boolean values used in the Fault Tree, including the use of Fuzzy Logic. In order to test the program, a simplified model of the Almirante Alvaro Alberto 2 Nuclear Power Plant (Angra-2) manuals was used and with this model, simulations were performed to analyze the program's operation and if it leads to the expected results. The results of the tests presented a quick identification of the events and great accuracy, demonstrating the applicability of the model to the problem. (author)

2015-01-01

In the history of nuclear power plants operation safety is an important factor to be considered and for this, the use of resistant materials and the application of redundant systems are used to make a plant with high reliability. Through the acquisition of experience with time and accidents that happened in the area, it was observed that the importance of creating methods that simplify the operator work in making decisions in accidents scenarios is an important factor in ensuring the safety of nuclear power plants. This work aims to create a program made with the Python language, which with the use of an expert systems be able to apply, in real time, the rules contained in the Limiting Conditions for Operation (LCO) and tell to the operator the occurrence of any limiting conditions and the occurrence of failure to perform the require actions in the time to completion. The generic structure used to represent the knowledge of the expert system was a fault tree where the events of this tree are objects in program. To test the accuracy of the program a simplified model of a fault tree was used that represents the LCO of the nuclear power station named Central Nuclear Almirante Alvaro Alberto 1. With the results obtained in the analysis of the simplified model it was observed a significant reduction in the time to identify the LCO, showing that the implementation of this program to more complex models of fault tree would be viable.(author)

Full Text Available A partir da análise do livro de estreia de Alberto Rangel, Inferno verde, publicado em 1908, o artigo busca identificar as motivações e os constrangimentos presentes no processo criativo do autor quanto à formulação de uma representação da Amazônia como sertão. A sua filiação ao estilo de Euclides da Cunha e a sua vinculação ao aparato administrativo estatal quando da sua presença na região confluíram para uma ideia de região então assentada em seu aspecto infernista. O entendimento da realidade nacional a partir dos sertões fez com que a Amazônia fosse tomada pelo autor como um mundo relegado ao esquecimento. Uma interpretação dos diferentes contos do livro e a identificação de uma representação infernista da Amazônia só poderão ser logradas caso leve-se em consideração os aspectos vinculados aos anseios e angústias de Alberto Rangel em tornar-se um escritor e ser reconhecido como tal.Based on the book debut of Alberto Rangel, Inferno Verde (Green Hell, published in 1908, this article investigates the motivations and constraints present in the author's creative process, regarding the representation of the Amazon as sertão (backlands. His adherence to the style of Euclides da Cunha, and his relationship with the state administrative apparatus when he was in the region, contributed to the idea of what seemed to be a hellish aspect of the Amazon. In his understanding of the national reality, in relation to the backlands, the author saw the Amazon as a forgotten world. For a different interpretation of the stories in the book, and the recognition of this hellish representation of the Amazon, it is necessary to take into consideration the aspects related to the aspirations and anxieties of Alberto Rangel on becoming a writer and to be recognized as such.

These critical points are enhanced to permit the discussion of a methodological approach that is supposed to be suitable to the reality of Angra dos Reis. The approach was developed specifically to this region and was introduced as a part of the general emergency off-site plan to the Central Nuclear Almirante Alvaro Alberto (CNAAA). Starting from this experience will be possible to enlarge this approach in a further research, in order to study this potential hazards of other industrial plants. (author)

Camargo, C.T.M.

1978-06-01

A calculation model to analyze reactivity insertion accidents in a PWR reactor was developed. To analyze the nuclear power transient, the AIREK-III code was used, which simulates the conventional point-kinetic equations with six groups of delayed neutron precursors. Some modifications were made to generalize and to adapt the program to solve the proposed problems. A transient thermal analysis model was developed which simulates the heat transfer process in a cross section of a UO 2 fuel rod with Zircalloy clad, a gap fullfilled with Helium gas and the correspondent coolant channel, using as input the nulcear power transient calculated by AIREK-III. The behavior of ANGRA-i reactor was analized during two types of accidents: - uncontrolled rod withdrawal from subcritical condition; - uncontrolled rod withdrawal at power. The results and conclusions obtained will be used in the license process of the Unit 1 of the Central Nuclear Almirante Alvaro Alberto. (Author) [pt

The magazine target was Brazilian and foreign schools and universities, his students and whoever was interested on culture, science, politics or signed articles. This publication purpose was to be the divulgation vehicle of new cultural and scientific ideas, most of them produced by Brazilian researchers, intellectuals and artists.

The editorials were signed by the magazine director - Paulo Duarte - one of the intellectuals with participation in the University of Sao Paulo foundation.

Full Text Available À la tête du Pérou de 1990 à 2000, Alberto Fujimori a su rester populaire en combinant les recettes traditionnelles et nouvelles du populisme. Le discrédit des partis politiques et des syndicats a constitué un contexte favorable à l’arrivée et au maintien au pouvoir de ce non-professionnel de la politique, auquel des valeurs d’honnêteté et de compétence ont été spontanément prêtées. Le chef d’Etat péruvien a construit en outre, tout au long de ses mandats successifs, une stratégie politique destinée à asseoir sa légitimité. Cette stratégie s’est fondée sur des actions telles que : la mise en place d’une relation directe et quasi affective avec les couches les plus défavorisées de la population par le biais de pratiques clientélistes ; la déstructuration du tissu social dans l’objectif d’éviter toute opposition et de renforcer le pouvoir du chef de l’Etat ; l’instrumentalisation de certains groupes d’acteurs, notamment par l’intermédiaire des programmes sociaux ; enfin, le contrôle permanent, et sans cesse renforcé, de l’information, via la surveillance des médias et des opposants. Fondée sur une image d’efficacité, la gestion politique d’Alberto Fujimori est demeurée populaire jusqu’à la fin des années 1990, lorsque la révélation d’affaires de corruption a accéléré la chute de son régime.Presidente de Perú de 1990 a 2000, Alberto Fujimori supo conservar su popularidad mezclando viejas y nuevas recetas del populismo.

For present purposes it is important to consider criticism in a double sense: first of all, a way of explanation of some of the procedure language, so that poetic writing is presented as a procedure that folds over their own means, which allows reflection and valorization on the writing evidence; and, in another possible approach, criticism towards a detailed examination followed by evaluation about the motivating fact on which this long poem was wrote (violence - followed by death - suffered by the transsexual Gisberta Salce in Porto/Portugal –, at this moment of the analyses, the conjunction of ethics and aesthetics will be relevant. Alberto Pimenta also wrote critical essays, which matter consider this third meaning of criticism: a characteristic literary genre that will be the basis of some of the reflections raised by the poem. We intend to think how the criticism and the poetry are confluents achievements in Alberto Pimenta activity.

The measurements of photon radiation field intensity are usually performed by a radiation protection technician trained and having skill in using radiation rate meters. Nowadays, these measurements are reported on exposure quantity and used to protect exposed individuals against the radiation risks while executing their activities. The International Commission on Radiation Units and Measurements - ICRU - defined the operational quantity ambient equivalent dose H{sup *}(10). This quantity is accepted by the scientific community as the best estimative of the protection quantity effective dose, which can not be directly measured. The operational quantity H{sup *}(10) was introduced in Brazilian rules by the National Commission of Nuclear Energy - CNEN (2005a), although its adoption was conditioned to studies of convenience and applicability of implementation. The present work may contribute to these studies, as it presents the evaluation of H{sup *}(10)'s implementation at the Nuclear Central Almirante Alvaro Alberto - CNAAA. The evaluation involved radiological tests - the energy dependence and angular dependence - applied to six types of photon radiation rate meters utilized at the CNAAA, with represent around 83% of the total number of rate meters in use by CNAAA. The result of this evaluation is favorable to the quantity H{sup *}(10)'s implementation. Suggestions are presented in order to update de rate meters and the technical and administrative procedures related to the Laboratory of Calibration of Rate Meters - LCMR, belonging to CNAAA. Thus, it could be possible to perform the calibration of the rate meters at the nuclear installation. The results obtained allows to carry out new evaluations of H{sup *}(10)'s implementation on installations that perform measurements with radiation rate meters on the practice of radiation protection, in order to adopt the H{sup *}(10) quantity in our country.

Among the planning activities of actuation in nuclear/radiological emergences, it is included the efficiency evaluation of protection and remediation measurements. From the development of a data base on such measurements for the agricultural areas, the program SIEM was used for effectuation the simulations involving the {sup 137}Cs, {sup 131}I and {sup 90}Sr radionuclides, in scenery previously established for simulation those areas of a 50 km surrounding the Admiral Alvaro Alberto nuclear power plant. The obtained results indicate that the scenery is determinant of efficiency measurements involving various specific factors of each place, such as: agricultural and cattle breeding products, consumption habits of population and the grade of subsistence by the diet items, making not practical the elaboration of predefined generic sceneries. The great dependence on seasoning related to the moment of accident makes inadequate any previous evaluation what soever for evaluation of efficiency of protection and remediation measurements. Therefore, previous decisions are not recommended about the relevance of protection measurements for rural areas. Two classification criteria were defined: (i) the efficiency in reduction the doses in the firs year; and, (i i) efficiency in reduction the dose at long term

Among the planning activities of actuation in nuclear/radiological emergences, it is included the efficiency evaluation of protection and remediation measurements. From the development of a data base on such measurements for the agricultural areas, the program SIEM was used for effectuation the simulations involving the 137 Cs, 131 I and 90 Sr radionuclides, in scenery previously established for simulation those areas of a 50 km surrounding the Admiral Alvaro Alberto nuclear power plant. The obtained results indicate that the scenery is determinant of efficiency measurements involving various specific factors of each place, such as: agricultural and cattle breeding products, consumption habits of population and the grade of subsistence by the diet items, making not practical the elaboration of predefined generic sceneries. The great dependence on seasoning related to the moment of accident makes inadequate any previous evaluation what soever for evaluation of efficiency of protection and remediation measurements. Therefore, previous decisions are not recommended about the relevance of protection measurements for rural areas. Two classification criteria were defined: (i) the efficiency in reduction the doses in the firs year; and, (i i) efficiency in reduction the dose at long term

Full Text Available This article addresses, in a punctual way, some reflections on the judicial activism in the Special Courts camp. It seeks to evaluate the existence of a place for the conciliator in the stir that permeates the procedural and substantial models of legal proceedings. For this, as theoretical references, the postulates of Luis Alberto Warat are used, in order to overcome such dyad in favor of an effective judicial protection, without following the ways of the Free Movement of Law and Instrumentality of Process. For the development of this research, it has been used the inductive method, operated by the operational concepts and techniques of literature.Resumo: O presente artigo aborda de forma pontual algumas reflexões sobre o ativismo judicial na seara dos Juizados Especiais. Procura-se avaliar a existência de um lugar para o conciliador na celeuma que permeia os modelos procedimentalistas e substancialistas de processo jurisdicional. Para tanto, como referencial teórico utiliza-se os postulados de Luis Alberto Warat no intuito de superar a referida díade em favor de uma tutela judicial efetiva, sem que se trilhe os caminhos do Movimento do Direito Livre e da Instrumentalidade do Processo. Utilizou-se, para o desenvolvimento desta pesquisa, o método indutivo, operacionalizado pelas técnicas de conceitos operacionais e da pesquisa bibliográfica.

Full Text Available El Espectador sevillano is a journal that was edited by Alberto Lista between 1809 (2 October and 1810 (29 January. It happened to be published in Seville for the town had just become the capital city of unoccupied Spain. El Espectador sevillano provides us with a systematic account of the fundaments of political liberalism as a doctrine that led to the writing of the Constitution of Cadiz a few months after the termination of the journal. However little attention has been paid to El Espectador sevillano despite it is being one of the most political influential journals at that time. In this paper, we fill in this research gap by locating El Espectador sevillano within the complexity of the vibrant political debate that took place in Seville during this period, in order to assess to what extend Lista’s thinking in 1809 can be labelled as revolutionary. | El Espectador sevillano, redactado por Alberto Lista, se publicó en Sevilla del 2 de octubre de 1809 al 29 de enero de 1810. Aunque se trata de uno de los periódicos más importantes del momento, se le ha estudiado poco. Redactado en la ciudad que, por las circunstancias bélicas, había pasado a ser capital de la España libre, ofrece una exposición sistemática de los fundamentos de la doctrina política liberal, que se plasmarían algunos meses después en la Constitución de Cádiz. En estas breves reflexiones, se trata de situar la publicación en el complejo e intenso debate de ideas de que fue entonces teatro Sevilla, para tratar de determinar hasta qué punto puede calificarse de revolucionario el pensamiento del Lista de 1809.

Full Text Available La traducción - auténtica o falsa - desempeña un papel importante en la obra de Alberto Mussa. Las supuestas fuentes de sus novelas incluyen lenguas como el árabe, el tupí, el francés o el alemán, y el propio autor ensaya también la traducción, en un ejercicio que revela una idea muy borgiana de ésta: en literatura no existe origen, solamente rescrituras. Mussa usa en su obra la traducción como pretexto, como recurso estético y narrativo, y también como evidencia de una concepción del lenguaje humano como juego y como fin en sí mismo. Para Mussa, como para Borges, traducir no es repetir, sino recrear, y el traductor, tanto si quiere como si no, está condenado a ser poeta, ya que “las palabras no son ni siquiera sinónimas de sí mismas”.

In 2011, in Brazil, a National Intercalibration and Intercomparison exercise on in vivo measurement of iodine-131 in the thyroid was carried out in the scope of the Project IAEABRA9055 'Establishing a National Laboratory Network for Internal Individual Monitoring'. The exercise was conducted by the Institute for Radiation Protection and Dosimetry (IRD) and the Institute for Nuclear and Energetic Research (IPEN), from National Nuclear Energy Commission (CNEN). The objectives of the exercise were to (i) update information on current instrumentation resources available in the in vivo monitoring laboratories in operation in Brazil and to (ii) verify the reliability of the results of measurements of iodine-131 in thyroid provided by those laboratories. The procedure consisted on the measurement of a neck-thyroid anthropomorphic phantom provided by the In Vivo Monitoring Laboratory of IRD, containing two barium-133 standard sources certified by the National Laboratory for Metrology of Ionizing Radiation. Each participant should measure the phantom in a period of five days. The five laboratories are located in the States of Rio de Janeiro, Sao Paulo, Minas Gerais and Pernambuco, in the following Institutions: Institute for Radiation Protection and Dosimetry, Nuclear Power Station Almirante Alvaro Alberto, Center for the Development of Nuclear Technology, Institute for Nuclear and Energetic Research, and Regional Center for Nuclear Sciences. The results reported included: activity measured, minimum detectable activity, accuracy and precision. The performance of the laboratories was evaluated according to the criteria suggested by ANSI 13.30 indicating their capacity to provide reliable results of iodine-131 content in the thyroid.

Full Text Available La tesis de este ensayo postula que la narrativa de Alberto Fuguet puede ser leída como un proyecto escriturario que propone una (nueva estrategia retórica por la cual representar los desvíos del género sexual. Según este modus operandi, en las narraciones de Fuguet, tanto el acto de reprimir como el de explicitar los desvíos de la masculinidad, se ejecutan a través de un juego de citas a la tradición literaria chilena. En los textos de José Donoso, Jorge Edwards y Alfredo Gómez Morel, entre otros, los narradores personajes de Fuguet encuentran un conjunto de figuras retóricas que les permite decir su desvío, pero de manera oblicua; es decir, cifrando la voluptuosidad de sus deseos en la lengua culturalmente prestigiosa del Canon de las Letras de Chile. Dentro de este contexto, este ensayo pesquisa las citas que los primeros trabajos de Fuguet (Sobredosis y Mala onda hacen de Casa de campo y El jardín de al lado, de José Donoso, y El río, de Alfredo Gómez Morel.This essay proposes that Alberto Fuguet s narrative may be read as a writing project with a (new rhetorical strategy by which various sexual deviances may be represented By this modus operandi, in Fuguet's stories, both manifestation and repression of male deviance are made explicit by way of a 'quotation game' in the field of Chilean literary tradition.

Full Text Available The attitudes and beliefs that archaeologists bring to their profession can have important impacts upon the manner in which they approach their work; therefore, studying an archaeologist’s life can shed light on archaeological history. An investigation of the early life of the Mexican archaeologist Alberto Ruz Lhuillier provides fascinating evidence of just how life experiences can have an impact on attitudes and theoretical approaches. Ruz was the archaeologist who, in 1952, discovered the magnificent tomb of the Classic Maya King of Palenque, Mexico, K’inich Janaab’ Pakal I. Research into Ruz’s early life sheds light on why he had negative opinions about the United States (US, and highlights the experiences that caused them, and explains how they changed. When Ruz moved to Cuba in the 1930s, and learned about the impact of American interference in Cuban affairs, he became deeply involved in the socialist revolution to oust Cuba’s US puppet dictators and to free his country from ‘yanqui’ imperialism. In addition, these early student life experiences exposed him to other students who espoused the theories and ideas of Karl Marx. Later Ruz would use some of these theories to explain the development and fall of ancient Maya civilization.

Esta "transición autoritaria" ha dejado su registro público, pese a las estrategias de ocultamiento, en los mensajes que el presidente de la república dirigió a la nación cada 28 de julio con motivo de la celebración de la Independencia. En los once mensajes que dirigió Fujimori al país, se encuentran las marcas de su estrategia política general: la consolidación de su imagen de salvador de la nación con la anuencia del pueblo; el fortalecimiento de las instancias ejecutivas del Estado sin necesidad de fiscalización política o judicial, y la polarización de las identidades políticas en una supuesta comunicación directa entre el presidente y las mayorías del Pení. Mediante el análisis sistemático de los mensajes presidenciales, se describe cómo el presidente Fujimori ejerció el discurso político como acción privilegiada durante sus años de gobierno para buscar una legitimidad que prescindiera de la deliberación política

Persistency of atmospheric diffusion conditions in Angra dos Reis - Brazil

International Nuclear Information System (INIS)

Nicolli, D.

1981-12-01

Based on a 2 year observation period, the diffusion conditions at the Almirante Alvaro Alberto N.P.P. site, in Angra dos Reis, are analized with respect to persistency as a function of the wind direction, the Pasquill stability class and the time of the day. The Pasquill stability class relates to the bulk vertical temperature gradient measured between 2m and 50m in the atmosphere; the wind direction is measured at 50m height. The persistency is defined in this report as the probability that the wind direction will remain longer than a given time in a sector without change in the diffusion category by more than a certain stage. During the day the persistency is mostly affected by the sea breeze with predominance of the unstable and neutral categories. At night the stable categories dominate. The alternating sea and land breezes disturb daily the trade wind field resulting in low persistency of the diffusion conditions. (Author) [pt

The analysis proposed will be based on some of the Reception Aesthetics concepts mainly focusing on enriching the sensory aspects of the text, especially the visual one. For that purpose, the poetic devices used in the construction of the text as well as its reception by the readers will be highlighted. The analysis will be based on the concepts theorized by Wolfgang Iser. Such concepts are: a the interaction between text and reader and the position of the latter at the time of the former reception; b the blank places; c the negation and negativity structures; and d it will also consider the approach to reading as an act in which the reader is responsible for achieving the meaning for the text and for creating an “aesthetic pleasure” through it. This last concept is grounded in Hans Robert Jauss theory.

Analisa diversos pontos de sua trajetória de cientista, ativista e professor. A atenção recai especialmente sobre as suas três principais produções literárias, publicadas entre 1926 e 1935, nas quais focaliza a distribuição geográfica dos conjuntos de vegetação do Brasil e propõe diversos programas de aproveitamento racional e de preservação dos recursos naturais brasileiros. Mostra-se que as suas idéias estavam influenciadas pelos ideais de um estado forte capaz de construir uma nova identidade nacional, com base na riqueza da natureza brasileira. A conclusão é que as idéias de Sampaio foram avançadas para a sua época e que elas conservam grande parte de sua atualidade, mesmo depois de décadas de prevalência de uma ideologia desenvolvimentista em que ele e diversos cientistas naturais conservacionistas seus contemporâneos foram quase inteiramente esquecidos.The text discusses the scientific output and the proposals for nature protection by the Brazilian botanist Alberto José Sampaio (1881- 1946, one of Brazil.s leading plant scientists and one of the country.s pioneer conservationists.

The emphasis falls on his three major books, published between 1926 and 1935, in which he writes about the geographic distribution of Brazil's vegetational forms and presents many proposals in favor of the rational use and preservation of the country.s natural resources. It is shown that his proposals were influenced by the concept of the need of a strong State that could build a new national identity, based on Brazilian nature.

Full Text Available A crítica da modernidade se tornou debate comum nas últimas décadas do século XX, empreendida por autores preocupados com a construção de alternativas societárias. Uma das linhas teóricas centrais do debate refere-se ao conceito de racionalidade, tendo sido preocupação central em Weber, Mannheim, Horkheimer, Adorno e outros. Alberto Guerreiro Ramos, expoente sociólogo brasileiro da segunda metade do século XX, propõe uma crítica da modernidade pela perspectiva de sua racionalidade organizacional, condensada em sua Teoria da Síndrome Comportamentalista. Essa teoria tenta compreender os fundamentos e as dimensões básicas da razão moderna: Individualismo, Perspectivismo, Formalismo e Operacionalismo. Em suma, a teoria mostra que vivemos imersos numa razão centrada no mercado, que fomenta comportamentos em detrimento da ação (criativa e que reduz a capacidade racional humana aos seus aspectos instrumentais e mercadológicos. A partir disso, tentaremos compreender em que medida a racionalidade moderna acaba forjando um paradigma educacional funcionalista, reprodutivista e mecanomórfico. The critic of the modernity became common debate in the last decades of the century XX, undertaken by authors worried with the construction of alternative partners. One of the central theoretical lines of the debate refers to the concept of rationality of the modernity, having been central concern in Weber, Mannheim, Horkheimer, Adorno and others. Alberto Guerreiro Ramos, exponent Brazilian sociologist of the second half of the century XX, proposes a critic of the modernity for the perspective of its rationality organizacional, condensed in its Syndrome Theory Behavioral. That theory tries to understand the foundations and the basic dimensions of the modern reason: individualism, perspectivism, formalism and operationalism.

The Almirante Alvaro Alberto Nuclear Center (CNAAA), located at the city of Rio de Janeiro and the liquid effluents are released into the Ilha Grande Bay (BIG). The objective of this work was to simulate mathematically the dispersion of 3 H and 137 Cs present in the liquid effluents that are routinely released into the environment, and in this way contribute to the improvement of the radiological impact assessment associated to these releases. The hydrodynamic circulation pattern of the bay and the transport of radionuclides were simulated by means of numerical modeling techniques by the computational system SisBAHIA (Sistema Base Hidrodinâmica e Ambiental). The results indicate that the local circulation pattern is mainly driven by the propagation of the tidal wave, and is characterized by low current velocities of about 0.1 m.s -1 . The wind stress (normal or extreme ones ) over the free surface does not alter the local circulation pattern significantly. The effluents are released in a rate of about 120 m 3 .s. -1 . As a result, the local hydrodynamics is markedly altered by means of the formation of a huge vortices close to the release area. According to the annual amount of the released radionuclides predicted in the Nuclear Licensing Document, and considering a continuous release it could be predicted that the radionuclide plume would present a low mobility, with most of the activity concentration amount being restricted close to the source. The activity concentration distribution reach the transportation steady state by the end of the 51 st day of simulation. A conservative behavior of both radionuclides in the water column was assumed in the performed simulation. (author)

Full Text Available What remains of angels?: A re-reading of the novel of Fra’ Alberto (Decameron IV, 2, between the masks of the angel and the uom selvaticoBoccaccio’s novel about brother Alberto is usually considered an amusing divertissement presented by the author himself as a contrast to the preceding tragic novel involving Tancredi and Ghismunda. A much more serious meaning can be found, however, beyond the comic facet, this being a deep and somewhat bitter vision of a man living in the Late Middle Ages, lost between the earthly and heavenly dimension. This article exploits the well known visual aspects of Boccaccio’s novels and focuses on the visual representation of the main character and its iconographical connotations, which in certain cases seems to fill up the silence of the text. Two of Alberto’s masks (the intentional mask of the angel and the punitive mask of ‘uom salvatico’ appear imperfect, provisional and actually overlap one other. This image places both the real and fictional identities of the character at risk and converges them in a sort of final metamorphosis and equation. On a textual level, this concept is supported by the high incidence of the terms ‘agnolo’ and ‘salvatico’, as well as by a pun based on a false etymological affinity between ‘salvatore’ and ‘salvatico’ (the same used by Edmund Spenser in his The Faerie Queene.

In searching for the rots of minimalism in architecture: Formal silence of Adolf Loos

Full Text Available Architectural examples of minimalism, combined with strict forms of modern movements, and the possibilities offered by new materials and technologies, contributing to the triumph of aesthetics that has become a symbol of our times. Minimalism in architecture, as the most original contribution to the idea of simplicity in architecture today has its roots in different areas as well as creation of prominent individuals - copyright strong individualities that do not tolerate any kind of categorization. One such author is certainly Adolf Loos. His theoretical ideas regarding decorations were sensational, because while the modernists had a dilemma about where and how to place ornaments, Los was adamant: his drastic solution predicted the complete elimination of ornament. In our time, minimalist architecture brings the ease of Adolf Loosa, whose design is rejected historicism and its parasites, decoration, to the pronounced rationalism. It is possible to follow the guiding principle of his 'formal silence' by Carl Andre to Herzog i de Meuron, as well as over the Mediterranean vernacular architecture to Alberto Campo Baeza and Alvaro Siza.

Full Text Available A través de la lectura crítica de Por Favor ¡Plágienme! (1991, texto clave para la comprensión del universo estético y creativo de Alberto Laiseca, este artículo plantea reflexiones sobre el enfoque singular que su obra narrativa aporta al problema del plagio en la literatura contemporánea y postula, al mismo tiempo, la posibilidad de pensar la obra de Laiseca en tensa –y paródica– relación con la tradición literaria argentina y su canon. Esta lectura permitirá operar críticamente sobre el dispositivo central de la literatura laisecana, que consiste en desestabilizar los discursos teóricos disponibles sobre aspectos aplicables a su poética, como el del horizonte conceptual del plagio. Desde aquí se volverá posible pensar en los motivos por los cuales una crítica literaria hegemónica tiene hasta el momento poco diálogo con la obra de quien es, sin embargo, uno de los autores contemporáneos más prolíficos de la literatura argentina. Through the critical reading of Por Favor ¡Plágienme! (1991, a key text for understanding the aesthetic and creative universe of Alberto Laiseca, this article enquires into the unique approach that his narrative opens to the issue of plagiarism in contemporary literature. The article also postulates thinking Laiseca’s work in a tense –and parodic– relationship with the Argentinian literary tradition and its canon. This reading will operate on the central device of “Laisecan” literature, which consists on destabilizing available theoretical discourses over aspects that can be applied to his poetics, as the conceptual horizon of plagiarism. From here it will be possible to consider why a hegemonic literary criticism has had little dialogue with the work of someone who is, however, one of the most prolific contemporary writers of Argentinian literature.

Separation and radiometric determination of 59Ni, 63Ni, 55Fe, 99Tc and 94Nb in radioactive wastes of low and intermediate activities from PWR nuclear power plants

The objective of this work was the development and establishment of a specific analytical protocol for the determination of the 59 Ni, 63 Ni, 55 Fe, 99 Tc and 94 Nb radionuclides in low and intermediate radioactive waste samples of Almirante Alvaro Alberto Nuclear Power Plant, CNAAA, located in the city of Angra dos Reis, RJ. The separation and purification techniques used have taken into account the particularities of each radionuclide studied. Chemical separation methods were used, as well as carriers and radioisotope tracers, and ion-exchange and extraction chromatography involving specific resins. The main techniques used for the analysis and determination of the radionuclides were Liquid Scintillation Counting (LSC) and Gamma Spectrometry. Also used were Atomic Emission Spectroscopy with Inductively Coupled Plasma (ICP-AES) and Neutron Activation Analysis (NAA) for the chemical yield determination. Concerning to the 59 Ni, 63 Ni, 55 Fe radionuclides, the methodology of sequential separation proved to be very appropriate for their separation and determination, as could be observed by the results obtained. Chemical yields in the range from 39 to 100%, and LSC counting efficiencies in the range of 37.8% for 55 Fe, and 71.5% for 63 Ni, are in accordance with the results found in the literature. The spectra of LSC showed that the methodology used to separation and purification of these radionuclides was very successful. The results for 59 Ni have shown that the use of a 55 Fe certified standard for calibration of the equipment was a viable alternative. In the case of the 99 Tc radionuclide the use of rhenium as carrier and chemical yield monitor, resulted in high chemical yields. Use of Gamma Spectrometry analysis made it possible to check that the main interfering agents were actually removed with the combined use of anion exchange chromatography and TEVA resin. The chemical yield of 94 Nb was measured by Gamma Spectrometry analysis of the 94 mNb nuclide formed by

The present work aimed the study of the dispersion profiles of radionuclides released in liquid radioactive effluents from the Central Nuclear Almirante Alvaro Alberto (CNAAA), in the Ilha Grande Bay, located in Angra dos Reis, RJ. Taking the overall activity released by liquid effluents discharge from the CNAAA in the Piraquara de Fora Bay as a reference parameter to the dilution rates scanning, the accordance level between the achieved 3 H results (1 :16) and those reported by Franklin (1 :20) can be seen as relevant. The post-1965 137 Cs concentration raise can be regarded as a consequence of the operational start up in the CNAAA, being the Ribeira Bay considered its preferential uptake, from the plume displacement high tide, as well as its retention, due to local deposition favourable trends. The evaluation of the prevailing mechanism on long half-life radio isotopes dispersion pointed out its dependence on meteorological condition parameters, during the sampling procedures. If diffusion prevailingness occurs, both 223 Ra and 224 Ra distribution pathways result in diffusion coefficients ranging from 20,12 ± 3,81 - 21,07 ± 3,91 km 2 .d -1 to a 228 Ra offshore flux and time of residence of, respectively, 3,18 ± 1,01 x 108 Bq.d-1 and 25,35 ± 0,45 days.

Alberto Urrets-Zavalía Jr was born in Córdoba (Argentina) in 1920. Chairman of the Department of Ophthalmology of the National University of Córdoba and founder of the Cornea and Glaucoma Surgical Center in the same city, in 1956 he created the first residency programme in Ophthalmology in his country. He founded the first Eye Bank and introduced one of the first argon laser photocoagulators in South America. He authored around 200 scientific presentations and publications, describing new findings and clinical entities. Thus, his individualisation of the cyclovertical component in strabismus contributed to important evolution of ideas concerning pathogenesis and therapy in oculomotor disorders of infancy. He was the first to propose the dehydration of the vitreous body in glaucoma patients before ocular surgery and developed a fixation pick and scleral depressor for retinal detachment surgery. He also described a new technique, the V-Z procedures for the correction of senile ectropion. In 1968, he published his Décollement de la rétine, considered a masterpiece in retinal detachment literature for many years. Urrets-Zavalía died in his native city at the age of 89. His prolific scientific and educational contributions make him one of the most brilliant and influential ophthalmologists of the 20th-century. © The Author(s) 2014.

Full Text Available The present article offers an interpretation of Alberto Chimal’s first novel, The Slaves, published by this Mexican author in 2009, a novel proposing an analysis of sadomasochistic sexual relations. In the center of the narration, we encounter two couples, both homosexual, acting out various sadomasochistic practices ‒ some of them of an extreme nature: On the one hand, two women, one of them already older (Marlene and (supposedly the director of pornographic movies, and the other, almost still a girl (Yuyis live a relation of dominance and submission with the noteworthy complication that Marlene could even be the mother of her "slave girl". The second couple is formed by two men: Golo, a decadent millionaire, and his "slave" nicknamed "Mundo" ('World' who is frequently reduced to something like a dog or even an unanimated object. The whole novel consists of various sequences narrating what the two couples experience in their sex life until a final turning point is reached with the forced separation in both cases. Due to a narrative structure that makes as understand that we as readers depend completely on an unreliable narrator, even the most brutal atrocities tend to dissipate in the fog of probably fictitious games showing us the trompe-l'oeil of a monstrous storyline of serial sex crimes. With this peculiar narrative structure in mind, I emphasize the 'ludic' character of sadomasochistic 'plays' narrated all through the novel, trying to understand what 'sadomasochism' means as a sexual practice or identity and what consequences could be drawn from these practices with regard to the construction of different genders (in the case of this novel: masculine and feminine.

The Instituto de Investigaciones Cardiológicas (ININCA) was founded by Alberto C. Taquini in 1944 and directed by him during more than 50 years, until his death in 1998. The Institute was (and still is) dedicated to research in connection with CONICET (National Research Council) and to teaching within the Faculty of Medicine of the University of Buenos Aires. From the very beginning research was centered on hypertension, hypoxia and hemodynamic adaptations, renal physiology and electrolytes, arterial wall, cardiac metabolism, myocardial pharmacology and regulation of the circulation by the central nervous system. On the basis of Taquini's autobiographical notes, the experiments are reported which eventually led to the discovery of hypertensin, angiotensin and their relation with renin, together with the discussions promoted by the diverse hypotheses proposed by both national and international groups of investigators as the mechanism of hypertension. Taquini also played an important role in promoting science at national levels including his role as the first Secretary of Science and Technology from 1968 to 1971. He believed that scientific research is something more than planning and producing, that it also involves creating knowledge. As such he made many contributions to science, formed many disciples, and directed an Institute which is demonstrating its continuity.

The objective of this work was the development and establishment of a specific analytical protocol for the determination of the {sup 59}Ni, {sup 63}Ni, {sup 55}Fe, {sup 99}Tc and {sup 94}Nb radionuclides in low and intermediate radioactive waste samples of Almirante Alvaro Alberto Nuclear Power Plant, CNAAA, located in the city of Angra dos Reis, RJ. The separation and purification techniques used have taken into account the particularities of each radionuclide studied. Chemical separation methods were used, as well as carriers and radioisotope tracers, and ion-exchange and extraction chromatography involving specific resins. The main techniques used for the analysis and determination of the radionuclides were Liquid Scintillation Counting (LSC) and Gamma Spectrometry. Also used were Atomic Emission Spectroscopy with Inductively Coupled Plasma (ICP-AES) and Neutron Activation Analysis (NAA) for the chemical yield determination. Concerning to the {sup 59}Ni, {sup 63}Ni, {sup 55}Fe radionuclides, the methodology of sequential separation proved to be very appropriate for their separation and determination, as could be observed by the results obtained. Chemical yields in the range from 39 to 100%, and LSC counting efficiencies in the range of 37.8% for {sup 55}Fe, and 71.5% for {sup 63}Ni, are in accordance with the results found in the literature. The spectra of LSC showed that the methodology used to separation and purification of these radionuclides was very successful. The results for {sup 59}Ni have shown that the use of a {sup 55}Fe certified standard for calibration of the equipment was a viable alternative. In the case of the {sup 99}Tc radionuclide the use of rhenium as carrier and chemical yield monitor, resulted in high chemical yields. Use of Gamma Spectrometry analysis made it possible to check that the main interfering agents were actually removed with the combined use of anion exchange chromatography and TEVA resin. The chemical yield of {sup 94}Nb was

Full Text Available This study analyses chivalry, materialism, and the grotesque in Alberto Blest Gana’s El ideal de un calavera [The Ideal of a Rogue] (1863 under the light of Miguel de Cervantes’s Don Quijote’s part II (1615. It underscores the legacy of Cervantes on the Chilean author especially in his reflections on nation building. Unlike its author, Don Quijote eluded restriction and successfully reached the colonies; once there, author and text became a massive influence on intellectuals in the burgeoning Americas. Blest Gana, for example, created protagonists who were multi-dimensional and imbued with quixotic overtones. Praised by his counterparts, he created work that was finely detailed, with a goal of portraying the nation’s cultural practices at specifics points in history. Deploying techniques inspired by Honore de Balzac (also a reader of Don Quijote, Blest Gana illustrated the colourful aspects of his society. His sharp eye depicted and interpreted nationhood and society through the course of dramatic historical events in El ideal de un calavera by shining a bright light on the political and social enemies who emerged in the historical unravelling of the nation in the 1830s. The resulting kaleidoscope of astute, idealistic and cowardly individuals conveyed subtle yet definite Cervantesque tones.

When a radiological or nuclear accident that leads to the release of radioactive material to the environment occurs, it is important to implement protective and remediation measures in order to reduce human exposure to radionuclides. Therefore, it is necessary that the procedures to be chosen by the affected country authorities are the most efficient ones, which can only be defined based on previously established criteria. In Brazil, since the radiological accident in Goiania, in 1987, the development of tools to support decision-making in emergencies of this nature was started. The main objective of this work was to establish an acting basis for contaminated areas, in order to protect the individuals of public in case of any accident related to Almirante Alvaro Alberto nuclear power plant, in the municipality of Angra dos Reis (RJ), which leads to contamination to the environment and the consequent exposure of local population or from more distant regions to ionizing radiation. Initially, the high-risk areas near the location of the nuclear power plant were defined. Typical urban environments found in the main cities of these municipalities were surveyed, including homes, streets and recreation areas. The main characteristics of the study area were evaluated using images from Google Earth® and web pages of the municipalities. After the types of areas to be simulated were selected, these were quantified in terms of the number of residents, the size of the streets, and the number of trees, among others, per unit area. Considering the different housing characteristics for the selected municipalities, six main standard scenarios were developed for urban areas, including homes with different shielding, buildings and parks. The simulation of the procedures for each scenario was made with SIEM model, developed by the Institute of Radiation Protection and Dosimetry (IRD/CNEN), formed by the integration of various models including CORAL, focusing on agricultural areas

CNAAA spent fuel complementary storage building (UFC) construction and licensing: an overview of current status

The reprocessing of nuclear fuel assemblies could be a valuable solution in order to make available additional energy resources and also to decrease the volume of discarded materials. After the burning of nuclear fuel assemblies to produce electrical energy, these components have to be stored in the spent fuel pools of each unit, for at least 10 years, in order to decrease their residual heat. Even after this initial 10 year-period, these spent fuel assemblies still have a great amount of energy, which can be reused. Nowadays, the spent fuel materials can be reprocessed in order to produce electrical energy, or be stored to provide, in the future, an opportunity to decide how these materials will be treated. At the present moment, Brazil does not plan to reprocess these spent fuels assemblies, as performed by some other countries. Thus, Brazil intends to build a spent fuel long term intermediate storage facility to allow the chance to make a decision in the future, taking into account the available technology at that time. Considering the three CNAAA units (Angra 1, 2 and 3 of Central Nuclear Almirante Alvaro Alberto, the Brazilian nuclear power plant, located at Angra dos Reis county, Rio de Janeiro state) have a life time estimated in 60 years, and the intrinsical spent fuel pools storage capacity of these units, a Spent Fuel Complementary Storage Building - UFC has to be foreseen in order to increase the storage capacity of CNAAA. Therefore, the Spent Fuel Complementary Storage Building shall be in operation in 2018, capable to receive the first spent fuel assemblies from Angra 2 and, in the next year, from Angra 1. The same procedure will be applied for the spent fuel assemblies of Angra 3, currently in construction. The Spent Fuel Complementary Storage Building will be constructed and operated by Eletrobras Eletronuclear - the CNAAA owner - and will be located at the same site of the plant. Conceptually, the UFC will be built as a wet storage modality

Carlo Alberto Pagni, born in La Spezia, Italy, on February 13, 1931, was an eminent and respected professor of neurosurgery and chairman of the neurosurgical clinic of the University of Turin from 1980 to 2003. He died on March 1, 2009. As a professor of neurology and neurological surgery he was renowned as an expert on vascular, tumor, and functional neurosurgery. Beyond the Italian Neurosurgical Society, he was the doyen of functional neurosurgery, specializing in motor cortex stimulation for the treatment of focal dystonia, Parkinson's disease, and postictal spasticity and pain. His home was his castle, and his family was fundamental to his life. He shared with his wife, Sandra, his passion for piano playing and for their remarkable library, and together with friends, he and his wife enjoyed dinners with fine food and Barolo wines. Listening to this Grand Seigneur talking about and explaining the music of, above all, Ludwig van Beethoven, and Richard Wagner, one felt he was emotionally just "music and mind". You can imagine this from his books on music, chess, and neuroscience. Indeed, he adored playing correspondence chess worldwide. A sportsman too, he loved hiking, mountaineering, skiing, swimming, and fishing. Nature was his source for slowing down, for regenerating, and for collecting his strength for new projects and new challenges. Friends will remember Dr. Pagni as a Grand Seigneur.

Free Choice or Poverty Alleviation? Population Politics in Peru under Alberto Fujimori

Full Text Available In the second half of the 1990s, the Fujimori  government in Peru implemented a population  policy to sterilize poor, rural and indigenous  women according to quotas. How such a neoMalthusian policy was possible in a post-Cairo,  post-Beijing era of increasing attention for  women’s rights has, however, been relatively  understudied. This article argues that the government could impose such policies because 1 it  presented its plans with a deceiving rhetoric in  which emancipatory and developmental arguments were mixed to cover-up its interests in costeffective poverty-reduction through population  policies, and 2 because it could rely upon the  long-existing inequalities based on racism and  sexism that conditions the lives of poor Peruvians.  Unique auto-ethnographical material about Andean women’s reproductive lives, drawn up by a  feminist NGO, is used to underpin these arguments.  Resumen: ¿Opción libre o paliación de la pobreza? Políticas demográficas en Perú  durante el gobierno de Alberto FujimoriEn la segunda mitad de los años noventa, el gobierno de Fujimori en Perú implementó una polí- tica demográfica que consistió en esterilizar a las  mujeres pobres, del campo e indígenas, de acuerdo a un sistema de cuotas. Cómo fue posible  formular e implementar semejante política neomalthusiana después del Cairo y de Pekín, período  en el que se presta creciente atención a los derechos de las mujeres, ha sido, sin embargo, relativamente poco estudiado. Este artículo sostiene  que el gobierno pudo imponer esas medidas debido a que 1 presentó sus planes con un retórica  engañosa en la que se utilizaron argumentos  emancipatorios y de desarrollo para encubrir sus  intereses en la aplicación de políticas demográficas rentables de reducción de la pobreza, y 2  porque pudo descansar en las persistentes desigualdades derivadas del racismo y del sexismo,  que condicionan la vida de los peruanos

Enfermedad y muerte convocan el pasado, lo instan a hacerse (en el presente, aunque toda restitución sea imposible. Pero la muerte, al menos la propia, es inenarrable.

Full text: A complete physical protection system gathers three elements: equipment's, guards and procedures. The integration of these three elements will guarantee the efficiency of the overall PPS in such a way that it can meet the objectives that were defined during its project: clear and precise procedures will rule the relation between the technical factor (equipments/ hardware and software) and the human factor (guards). The technical factor is easily adapted ad upgraded to continue meet the objectives of the PPS; however, the human factor presents some resistance, internal and external, concerning the performance of its function within the overall PPS. The objective of this paper is to show the importance of the human factor as an integrant part of the PPS of a nuclear facility. 1. Good relationship between guards and other employees in a facility; 2. the knowledge and acceptance of rules and procedures; 3. and the awareness of the needing to implement security measures, as well as the cooperation with these measures to avoid unauthorized nuclear material removal from the facility or sabotage with consequent radioactive release will guarantee the success of the human factor within the overall PPS. In countries where there is no recent record of terrorist activities, as in Brazil's case, these three key factors are particularly critical, once the concept of security culture is not present in those people's way of life. The target public of this survey are the employees, including the guards of the security force, of the CNAAA - Central Nuclear Almirante Alvaro Alberto - consisting of Angra 1 and Angra 2 nuclear power plants. The tools used to came up with the conclusions of this work were two different kinds of questionnaires: a) one of the questionnaires was answered by the guards of the security force concerning their feelings or impressions about other employees' knowledge, acceptance and cooperation of/with the security measures applied on site, and their

Full Text Available A propósito del primer centenario del nacimiento (1907-2007, de Carlos Alberto Seguín, describimos tres facetas de su ejemplar trayectoria: sus años formativos, su presencia en la Facultad de Medicina de San Fernando, en el difícil periodo de los 60, y su digna actitud ante la muerte. Las avanzadas ideas sobre la nueva formación médica que Seguín postulaba, insistiendo en la necesidad de estudiar, diagnosticar y tratar tanto el área psicológica cuanto física del ser humano y no solo ‘su enfermedad’. Además, su propuesta metodológica de los ‘grupos formativos’, para que los estudiantes tuvieran la oportunidad de elaborar sus vivencias de contacto con el enfermo, no fueron bien comprendidas en la época que las formulara, creándose conflictos que el profesor prefirió evitar por el bien de la institución y porque comprendió que el estudiante de esa época no estaba dispuesto a realizar el esfuerzo necesario para tal logro. Su digna actitud ante la muerte se grafica en un verso que escribiera poco antes de morir. Seguín falleció el sábado 26 de agosto de 1995. Debe ser recordado como un paradigma docente sanmarquino.

Don Alvaro de Luna, at the height of his power, decided to build a funerary chapel in Toledo Cathedral. In relation to this project Pedro Jalopa appears, possibly the same master who some years earlier had directed the construction of Huesca Cathedral under the patronage of Pope Benedict XIII, great-uncle of Don Alvaro. After his work in Toledo, Jalopa was contracted as master builder at Palencia Cathedral. The powerful Luna family and the close relationship between bishoprics may well have i...

O eu nacional: a constituição do ser brasileiro na visão de Alberto Torres e Monteiro Lobato = The national being: the constitution of the brazilian being in the vision of Alberto Torres and Monteiro Lobato

Margis, Simone Maciel

2014-01-01

Full Text Available O presente trabalho vincula-se ao projeto “História das Ideias, Historicidade e Identidades Culturais” do departamento de História da Universidade Federal de Santa Maria, coordenado pelo Prof. Dr. Carlos H. Armani, e, sob coorientação da mestranda do Programa de Pós-graduação em História – UFSM Jóice Anne A. Carvalho. Busca-se traçar uma linha teórica referente à constituição da Nação e o papel do indivíduo mergulhado na coletividade, ou seja, quem compõe e quem não compõe a estrutura social do Brasil na construção do eu nacional. Ao longo do século XIX e início do século XX, pensadores de várias áreas das ciências começaram a se questionar sobre as diferenças dos seres humanos e que, mais tarde, desembocariam num discurso hierárquico de raças. Essas menções à suposta inferioridade da raça brasileira fez com que Alberto Torres, assumisse uma posição contrária a esse discurso, expondo-a no livro “O Problema Nacional Brasileiro” (1914. Sua teoria sobre as raças afirmava que a única questão que podia vir a contribuir para certa diferenciação racial seriam os fatores mesológicos de uma Nação, mais precisamente, o clima. Nesta mesma linha de pensamento, o autor Monteiro Lobato também analisa a composição da população brasileira e a discussão acerca da hierarquização racial tão em voga no período. Em seu livro “Problema Vital” (1918, nega a afirmação de inferioridade da raça brasileira e aponta as medidas que o Estado deveria tomar para que a população conseguisse atingir o progresso. Lobato também acaba resgatando a figura do caboclo, numa clara tendência de traçar um perfil para o brasileiro

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

Full Text Available After the publication of the paper by Alberto Giubilini and Francesca Minerva, two Italian researchers currently active in Australia, entitled After birth abortion: Why Should the baby live?, published in 2012, there was a great debate among scholars and journalists that induced many people to rethink the current conditions of life and death. The mass media have reported a strong controversy on this topic. Fitting into this heated exchange of views, the University Orientale of Naples, in the presence of the authors of the paper, hosted a seminar organized by CIRB (Centro Interuniversitario di Ricerca Bioetica of Naples to reflect on post‐birth abortion, which was attended by doctors, lawyers and philosophers. The meeting generated an interesting discussion on the main topics of bioethics, but left many unanswered questions.

On behalf of everyone involved in this work, I would like to thank the IAEA, the Nuclear Fusion journal team, the IOP, and specifically Mitsuru Kikuchi, for their support of this important award. I would also like to acknowledge the many important contributions made by the other ten papers nominated for this prize. Our paper investigates the physics of the H-mode pedestal in tokamaks, specifically the development of a predictive understanding of the pedestal structure based on electromagnetic instabilities which constrain it, and the testing of the resulting theoretical model (EPED) against detailed observations on multiple devices. In addition to making pedestal predictions for existing devices, the paper also presents predictions for ITER, including methods for optimizing its pedestal height and fusion performance. What made this work possible, and indeed a pleasure to be involved with, was an extensive set of collaborations, including theory-experiment, multi-institutional, and international collaborations. Many of these collaborations have gone on for over a decade, and have been fostered in part by the ITPA Pedestal Group. The eight authors of this paper, from five institutions, all made important contributions. Rich Groebner, Tom Osborne and Tony Leonard carried out dedicated experiments and data analysis on the DIII-D tokamak, testing the EPED model over a very wide range of parameters. Jerry Hughes led dedicated experiments on Alcator C-Mod which tested the model at high magnetic field and pedestal pressure. Marc Beurskens carried out experiments and data analysis on the JET tokamak, testing the model at large scale. Xueqiao Xu conducted two-fluid studies of diamagnetic stabilization, which enabled a more accurate treatment of this important effect. Finally, Howard Wilson and I have been working together for many years to develop analytic formalism

Nuclear energy and nuclear weapons

Robertson, J.A.L.

1983-06-01

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)

Nuclear blackmail and nuclear balance

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

The present generation of on-line nuclear orientation facilities promises to revolutionize the gathering of nuclear structure information, especially for the hitherto poorly known and understood nuclei far from stability. Following a brief review of the technological developments that have facilitated these experiments, the nuclear spectroscopic information that can be obtained is summarized. Applications to understanding nuclear structure are reviewed, and challenges for future studies are discussed. (orig.)

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)

La aparición del No. 21 de la Revista “MEDICINA”, órgano de la Academia Nacional de Medicina de Colombia, marca una fecha memorable para nuestra Institución, ya que un buen amigo, buen colombiano, admirador de la obra desarrollada por la Academia, en forma gentil y generosa, se ha encargado de la financiación total de nuestra publicación, en forma trimestral y en la que se editarán 7000 ejemplares para cada número los cuales se distribuirán también por cuenta de ITALMEX a los médicos colombianos. De esta forma, es un aporte indirecto a la medicina de Colombia, pues tendremos un buen número de lectores los cuales por sus comentarios a “MEDICINA”, nos suministrarán muchas ideas útiles. También este No. 21 tendrá un aspecto distinto en la carátula: su color pasará del negro, posiblemente algo triste, a recordar los colores del escudo de la Academia, dorado y verde, que han sido los tradicionales.

Se trata del Dr. Joaquín Ordoñez S., ampliamente conocido no sólo en el cuerpo médico, sino también en el mundo de las finanzas. Director General de un importante laboratorio farmacéutico, de mucha antiguedad, gran prestigio y que goza de la confianza de todos los médicos: ITALMEX.

Debo recordar que hace varios años, también el Dr. Ordóñez financió en su totalidad la publicación del libro “TEMAS MEDICaS”, órgano oficial de la Academia, de los tomos VII al XI, libro que ha obtenido mucha acogida científica, y hace parte de las bibliotecas de muchos colegas. Nuevamente hoy se vincula a la Academia con nuestra Revista, el Dr. Ordóñez sea bienvenido!

Es importante conocer algunos datos sobre la vida y actividad de nuestro patrocinador: su gran personalidad es su tarjeta de presentación. Una marcada disciplina que en todas sus labores transmite a su grupo de trabajo; todo debe ser perfecto y en las fechas acordadas; muy buen madrugador, con amabilidad, educación y dinámica permanentes, sus colabordadores encuentran siempre al jefe y al amigo. Además, las situaciones difíciles, las arregla con un particular sentido de equilibrio y sabiduría. Cualquier punto de vista de su equipo de trabajo lo oye, lo estudia y acepta si es razonable y siempre previendo el futuro. Es un verdadero guía de Alta Gerencia y así lo reconoció la UNIVERSIDAD DE NEW YORK, al otorgarle el doctorado Honoris Causa de Alta Gerencia el 31 de septiembre de 1978, en ceremonia especial; es sencillamente el reconocimiento a su actividad laboral, iniciada el 14 de agosto de 1943, en la industria farmacéutica colombiana, la cual lo llevó a la Presidencia de AFlDRO no hace muchos años, yen donde desarrolló gran labor en pro de la Farmacología y Economía, otra de las predilecciones de su estudio permanente, junto con las Ciencias de la Administración, y por eso ha podido actuar con gran éxito como consejero de muchos personajes colombianos. Además de esas cualidades, es un ferviente creyente católico, sin querer nunca imponer sus puntos de vista, pues conoce también la humildad para hacer el bien de muchos necesitados, siguiendo el ejemplo de Cristo. Por esa gran cualidad humana obtuvo del VATICANO y de manos de su Santidad Juan Pablo II, el título de Caballero Comendador de la Orden de San Gregario Magno, en Roma el 29 de mayo de 1979. Finalmente, tiene un especial don para la Publicidad que parece nació con él. Ejemplo de ésto, es la Colección de Médicos Célebres colombianos 1 Etapa, entregada el Día Panamericano del Médico, en una fiesta memorable, ofrecida al cuerpo médico el pasado 10 de diciembre de 1989, en el Salón Rojo del Hotel Tequendama.

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

The Japan Atomic Energy Agency (JAEA) held “International Forum on Peaceful Use of Nuclear Energy, Nuclear Non-proliferation and Nuclear Security – Ensuring Nuclear Non-Proliferation and Nuclear Security of Nuclear Fuel Cycle Options in consideration of the Accident at TEPCO's Fukushima Daiichi Nuclear Power Station –” on 3 and 4 December 2013, with the Japan Institute of International Affairs (JIIA) and School of Engineering, The University of Tokyo, as co-hosts. In the Forum, officials from Japan, the United States, France and International Atomic Energy Agency (IAEA) explained their efforts regarding peaceful use of nuclear energy and nuclear non-proliferation. Discussion was made in two panels, entitled “Nuclear non-proliferation and nuclear security measures of nuclear fuel cycle options in consideration of the Accident at TEPCO's Fukushima Daiichi Nuclear Power Station” and “Roles of safeguards and technical measures for ensuring nuclear non-proliferation for nuclear fuel cycle options”. In the first panel based on the implications of the Accident at TEPCO's Fukushima Daiichi Nuclear Power Station on the domestic and global nuclear energy use and increased interest in the back end of nuclear fuel cycle, discussion was made on nuclear non-proliferation and nuclear security challenges on both fuel cycle options from the policy and institutional viewpoints whereas in the second panel the roles of safeguards and proliferation resistant nuclear technology including plutonium burning technology in ensuring nuclear non-proliferation and nuclear security in the back end of nuclear fuel cycle were discussed. Officials and experts from Japan, IAEA, the United States, France and Republic of Korea participated in the panel and made contributions to active discussion. This report includes abstracts of keynote speeches, summaries of two panel discussions and materials of the presentations in the forum. The editors take full responsibility for the wording

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

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).

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

Nuclear generation cost and nuclear research development fund

International Nuclear Information System (INIS)

Kim, S. S.; Song, G. D.

2000-01-01

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

2004-01-01

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.

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

International Nuclear Information System (INIS)

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

International Nuclear Information System (INIS)

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.

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

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

Ordinance on the control of nuclear material and special equipment lays down the list of nuclear materials and special equipment as well as of nuclear activities covered by the system of control of production of special equipment and non-nuclear material, the procedure for notifying the intention to and filing the application for a license to carry out nuclear activities, and the format and contents of the forms for doing so. This Ordinance also lays down the manner in which nuclear material records have to be kept, the procedure for notifying the State administration organization (regulatory body) responsible for nuclear safety by the nuclear material user, and the keeping of registers of nuclear activities, nuclear material and special equipment by the State administration organization (regulatory body) responsible for nuclear safety, as well as the form and content of official nuclear safety inspector identification card and badge.(author)

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

International Nuclear Information System (INIS)

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.

Dudder, G B; Niemeyer, S; Smith, D K; Kristo, M J

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

The Romanian nuclear regulatory body as a nuclear communicator

International Nuclear Information System (INIS)

Cluculescu, Cristina

2000-01-01

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.

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

International Nuclear Information System (INIS)

Hrnecek, E.; Mayer, K.; Schubert, A.; Wallenius, M.

2010-01-01

Nuclear forensics aims at identifying origin and intended use of nuclear material using information inherent to the nuclear material.The information gathered in nuclear forensics include isotopic composition, elemental composition, impurities and age of the material, macroscopic appearance and microstructure. The information so collected helps to solve criminal cases and put the individuals involved in nuclear trafficking in jails. The information also helps to improve safeguards and physical protection measures at place of theft or diversion to prevent future thefts or diversions.

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.)

El espectáculo político del acuerdo humanitario y la mediación de Hugo Chávez durante el segundo mandato de Álvaro Uribe

Directory of Open Access Journals (Sweden)

Manolo Constain

2012-12-01

Full Text Available During Alvaro Uribe's second term in power, diplomatic relations between Colombia and Venezuela were marked by severe difficulties that triggered several crises. With the arrival of Juan Manuel Santos to power, however, these difficulties seem to have been resolved unexpectedly fast. Hence, rather than being a crisis caused by some structural aspects of bilateral relations, the dispute was about misunderstandings and tensions that can be linked to specific dynamics of the relationship between Hugo Chávez and Alvaro Uribe. The authors use the concept of political spectacle proposed by Edelman (1988 in order to examine the relationship in question. From this perspective, the unsuccessful attempt to reach a humanitarian agreement with the mediation of Hugo Chávez that took place during the second half of 2007 can be considered as the first relevant event to analyze in the Venezuelan and Colombian leaders' conflictive interactions at the time. The article examines the way in which the political developments of this period were interpreted and transmitted by the El Tiempo newspaper immersed in a political spectacle that was based on a government-media relationship and aimed at generating support of the government in the public opinion through the symbolic use of the kidnapping issue.

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

Nuclear disarmament and the elimination of nuclear dangers

International Nuclear Information System (INIS)

Daerr, Hans-Joachim

2002-01-01

... today's threats to security and stability have become less predictable and require at the same time a joint response. They illustrate the need for a new international order organized around shared values, common norms of behaviour and the rule of law. Disarmament, arms control, and non-proliferation are indispensable elements of this cooperative international order... We have to make sure that the functions that are today attributed to nuclear weapons become dispensable ... Nuclear disarmament is the counterpart of the renunciation of nuclear weapons by non-nuclear-weapons states. This bargain must not be undermined ... The NPT is no licence to perpetuate the status of the nuclear 'haves' versus the nuclear 'have nots.' (author)

Nuclear material control systems for nuclear power plants

International Nuclear Information System (INIS)

1975-06-01

Paragraph 70.51(c) of 10 CFR Part 70 requires each licensee who is authorized to possess at any one time special nuclear material in a quantity exceeding one effective kilogram to establish, maintain, and follow written material control and accounting procedures that are sufficient to enable the licensee to account for the special nuclear material in his possession under license. While other paragraphs and sections of Part 70 provide specific requirements for nuclear material control systems for fuel cycle plants, such detailed requirements are not included for nuclear power reactors. This guide identifies elements acceptable to the NRC staff for a nuclear material control system for nuclear power reactors. (U.S.)

While nuclear sector activities remain contentious public issues, studies suggest that knowledge levels and trust in nuclear actors can influence public attitudes. Drawing on original data from a 2013 representative telephone survey of Saskatchewan residents, this paper considers the extent to which knowledge and trust influence support for nuclear developments. Saskatchewan provides an interesting case study: while the province has a robust uranium mining industry, there are no nuclear power facilities, and the potential development of nuclear energy and nuclear fuel waste storage has been a source of spirited public debate. The study's results have implications for public education and policy initiatives regarding nuclear power developments. (author)

Nuclear Liability and Insurance for nuclear Damage in Switzerland

International Nuclear Information System (INIS)

Reitsma, S. M. S.

1998-01-01

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 World Nuclear University: New partnership in nuclear education

International Nuclear Information System (INIS)

2007-07-01

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

Nuclear knowledge management

International Nuclear Information System (INIS)

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. In 2007, State Office for Nuclear Safety finalized the text of new Ordinance on conditions for nuclear safety and protection with regard to the siting, design, construction, use and decommissioning of a facility in which a nuclear activity is

1979-01-01

The written application concerning the change of nuclear reactor installation in the first nuclear ship was presented from the JNSDA to the prime minister on January 10, 1979. The contents of the change are the repair of the primary and secondary shields of the reactor, the additional installation of a storage tank for liquid wastes, and the extension of the period to stop the reactor in cold state. The inquiry from the prime minister to the Nuclear Safety Commission was made on June 9, 1979, through the examination of safety in the Nuclear Safety Bureau, Science and Technology Agency. The Nuclear Safety Commission instructed to the Committee for the Examination of Nuclear Reactor Safety on June 11, 1979, about the application of criteria stipulated in the law. The relevant letters and the drafts of examination papers concerning the technical capability and the safety in case of the change of nuclear reactor installation in the first nuclear ship are cited. The JNSDA and Sasebo Heavy Industries, Ltd. seem to have the sufficient technical capability to carry out this change. As the result of examination, it is recognized that the application presented by the JNSDA is in compliance with the criteria stipulated in the law concerning the regulation of nuclear raw materials, nuclear fuel materials and nuclear reactors.

Nuclear security and challenges at nuclear power plants. Part 1. Basis of nuclear security

International Nuclear Information System (INIS)

Demachi, Kazuyuki

2017-01-01

The tsunami that occurred in March 2011 associated with the 2011 off the Pacific coast of Tohoku Earthquake hit TEPCO Fukushima Daiichi Nuclear Power Station (1F). 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.

Alguien dijo -creo que fue Toynbee, el de “toda historia es contemporánea”- que para escribir la historia, hay que vivirla. Eso es lo que vemos quienes hemos leído el libro “La Visión de un Sueño” que se presenta esta noche, que mejor ha debido subtitularse “Una vida y una obra”, admirablemente sintetizada en las palabras de quienes me han precedido. Como los verdaderamente grandes, Alvaro emplea solamente el pronombre de tercera  persona, como si apenas se refiriera con modestia a ese “otro yo” que ha hecho las cosas más importantes en la oftalmología colombiana, dedicado siempre a construir obras magnas -comenzando por su familia, sus hijos-, a enseñar, a fundar, a hacer el bien. Parafraseando lo dicho recientemente por un gobernante en el homenaje póstumo a Rodrigo Lloreda Caicedo, la Academia debería reservar un nicho especial para aquellos que, mereciendo de sobra ser Presidentes, no han querido serlo por obedecer y cumplir antes el mandato hipocrático y humano que gobierna su vida. Sabemos que por cariño, por asiduidad, por generosidad, por nobleza, Alvaro y Helenita, seguirán siempre presidiendo en espíritu los corazones de quienes pertenecemos a esta ilustre corporación.

Efectivamente el libro de 180 páginas en gran formato, bellamente editado por Punto aparte Editores e impreso por Panamericana Formas e Impresos, con la asesoría editorial de Martalucía Tamayo y Sandra Roca Garavito está diseñado para impactar visualmente, como sí resaltara el lema de FUNDO-NAL grabado desde la contraportada: Su visión es mi misión. Dividido en cuatro grandes partes o capítulos, a saber: I.

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

International Nuclear Information System (INIS)

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

Schenkel, R.

2005-01-01

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.

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

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

A powerful new tool, Positron Emission Tomography (PET) was lauded as the impetus for new developments in nuclear medicine. The political environment (funding, degree of autonomy) was discussed, as were the economic and scientific environments

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

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.

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

Nuclear disarmament or survival of nuclear arms?

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..

Nuclear energy and nuclear technology

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

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

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.

Lastly, 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.

Nuclear waste problem: does new Europe need new nuclear energy?

International Nuclear Information System (INIS)

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)

In 1998, Nuclear Regulatory Authority of the Slovak Republic (NRA SR) performed 38 inspections, 25 of them were performed in co-operation with IAEA inspectors. There is no fresh nuclear fuel at Bohunice A-1 NPP at present. Fresh fuel of Bohunice V-1 and V-2 NPPs is inspected in the fresh fuel storage.There are 327 fresh fuel assemblies in Mochovce NPP fresh fuel storage. In addition to that, are also 71 small users of nuclear materials in Slovakia. In most cases they use: covers made of depleted uranium for non-destructive works, detection of level in production plants, covers for therapeutical sources at medical facilities. In. 1995, NRA SR issued 4 new licences for nuclear material withdrawal. In the next part manipulation with nuclear materials, spent fuel stores and illegal trafficking in nuclear materials are reported

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.

2001-02-01

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)

The nuclear nineties

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)
