  3. An experience of marine macrofouling control in Angra 1 - Almirante Alvaro Alberto nuclear power plant

    International Nuclear Information System (INIS)

    One of the greatest problems at the Power Plants that use sea water in the circulating water system, is the development of fouling in its sections. In Central Nuclear Almirante Alvaro Alberto - Angra 1, this fouling is represented by barnacles. These barnacles have contributed significantly to the damaging in the condenser tubes, resulting in the changing from cooper alloy tubes to Titanium ones. To help the understanding of the development and control of fouling, some researches and observations have been made using techniques adequated to Angra 1. The low-level continuous chlorination, the water flux variation and the continuous cleaning tubes system (AMERTAP) combined and used in circulation water sistem, showed satisfactory preliminar results in fouling control.

  11. Determination of concentration factors for Chromium cesium, iron and cobalt in corvine and shrimp in the vicinities of Almirante Alvaro Alberto Nuclear Power Plant

    International Nuclear Information System (INIS)

    In order to verify if the concentration factors for dose calculations in critical population recommended by the International Atomic Energy (IAEA), on the Safety Series 57, are in agreement with local factors, studies were carried out at Piraquara de Dentro bay, a region in the vicinities of the Almirante Alvaro Alberto Nuclear Power Plant (CNAAA). Chromium, caesium, iron and cobalt concentration factors for corvine and shrimp were determined using the activation analysis method by neutrons, taking into account the same behaviour between radioactive and stable from the same physicochemical form. This study has evidenced that: The local values of cesium, iron and cobalt concentration factors for corvine (fish) are in the same order of magnitude of the IAEA recommended values; The chromium, caesium and cobalt concentration factor values determined for shrimp for Piraquara de Dentro bay are in the same order of magnitude or smaller than those proposed by IAEA, while the concentration factor value for ion is one order of magnitude higher than the IAEA recommended value.

  13. Emission of 14C by the Almirante Alvaro Alberto Nuclear Power Plant 1 and 2 and their local effects on the environmental levels

    International Nuclear Information System (INIS)

    14C is a is a long-lived beta-emitting nuclide (T1/2 = 5730 years) produced naturally in the upper atmosphere as a result of reactions between neutrons and stable 14N(14N(n,p)14C). Although in a lesser extent, nuclear power plants produce 14C as well during their routine operation. Since it is converted in 14CO2 and mixed throughout the atmosphere, it is incorporated into plant tissues, via photosynthesis process, and hence in food chain. Because of the biological importance of 14C and long half-life, it is of interest to quantify the amounts released by nuclear industry. The Brazilian nuclear central named Nuclear Central Admiral Alvaro Alberto (CNAAA) has two nuclear reactors of PWR type in operation, Angra I (657 MWe) and Angra II (1350 MWe), and one under construction, Angra III (1309 MWe PWR). The aim of this study was to determine the strength of the sources and the 14C content in the environment through analyses of air, vegetation and soils taken within 5 km (the influenced area) of CNAAA. The thesis consists of an extensive review about the subject (part one) and of four papers (part two). The first paper is about the determination of 14C concentrations released by reactors (source strength). For Angra I, a device was developed in order to sample the gaseous effluents and for Angra II, a commercial monitoring system had already been implemented since its initial operation (2001). The 14C can be emitted as hydrocarbons, CO or CO2, depending on the type of reactor. For PWRs, the main chemical form released is hydrocarbons (80 %). The monitoring system of Angra I was planned to determine both CO2 and hydrocarbon fractions but in Angra II, all hydrocarbons are converted to CO2 by using a Pd/Al2O3 catalyst at 450 deg C. The liquid scintillation was the method employed to measure the samples. The second one concerns the atmospheric dispersion of the released radiocarbon through measurements of air samples taken with 3 km from power plants, in five different wind

    International Nuclear Information System (INIS)

    In this report, the Environmental Monitoring Program of the Uranium Enrichment Facility Almirante Alvaro Alberto is outlined and the results obtained during the preoperational period are presented. Information concerning the population distribution, the use of water and land, the local agricultural production and the local meteorology are also available. In order to evaluate the levels of the background radiation, sample of water, air and biological and terrestrial indicators were analysed. Measurements were performed of natural gamma emitters concentrations levels and of uranium in air, surface water, precipitation, groundwater, river sediment, soil, grass, vegetation and various foodstuffs. For direct measurement of background radiation levels a solid state dosimeter network was used. Results are also presented for the analysis of non radioactive pollutants in the water samples and for the particles and gaseous fluorides concentration in the atmosphere. (author)

  16. Risk analysis update of the Radiation Monitor Calibration Laboratory of the Almirante Alvaro Alberto Power Station

    International Nuclear Information System (INIS)

    In 2001, a Probabilistic Safety Assessment (PSA) of the Radiation Monitor Calibration Laboratory of the Almirante Alvaro Alberto Power Station (CNAAA) was performed. The main purpose of this work was to update the original PSA study and to obtain the updated radiologic risk, as well as to include a human reliability analysis of the procedure of radiation monitor calibration. Some accident scenarios were incorporated for evaluating their importance for an accident that might expose a worker to gamma radiation. For obtaining the probability of occurrence of an exposition of a worker during an accident, the Bayesian approach has been used for the calculation of the irradiator failure probability, for this approach is often used when few plant information is available. For the other equipment used in the radiation monitor calibration, the exponential distribution is used to model their failure times for they are assumed to be in their useful life period. The human reliability was modeled by the THERP technique. Although more accident scenarios are considered in this work, including the contribution of human errors, a conservative approach was not used and thus a smaller radiological risk, about one order magnitude smaller was obtained.

Su Il senso della morte e l'amore della vita nel Rinascimento, de 1957, es una obra maestra sobre los orígenes de la sensibilidad moderna: sin olvidar el naciente vitalismo, estudia el desarrollo de dos motivos, el del ars moriendi, que tiene su evolución propia desde 1350 hasta su difusión impresa, y el de lo macabro, que refleja la crisis de conciencia del siglo XV y adquiere «unas dimensiones desconocidas y verdaderamente anormales». En este libro sobre un problema clave como la muerte, apela de modo notable a la iconografía: Tenenti ha recordado que la cultura tradicional, eclesiástica sobre todo, percibió un mayor peligro en la capacidad de reflexión autónoma y de crítica de los hombres de letras, que en las renovaciones radicales de los artistas.

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

    International Nuclear Information System (INIS)

    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)

  8. The marine environment monitoring in Saco Piraquara de Fora after the beginning of the Angra 2 nuclear power plant operation

    International Nuclear Information System (INIS)

    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)

  13. Brazilian nuclear power plants decommissioning plan for a multiple reactor site

    International Nuclear Information System (INIS)

    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.

    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)

  20. 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)

    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.

  6. Reading W.G. Sebald with Alberto Giacometti

    Directory of Open Access Journals (Sweden)

    Timothy Matthews

    2006-09-01

    Full Text Available Where is Alberto Giacometti? The question seems to arise materially from an engagement with his art and the invitations it seems to extend. Much of his art is a life-long exploration of visual representation itself, of the attempt to visualise objects in a two or threedimensional space; to place people in space. But that placing is elusive, and the places seem to dissolve, making Giacometti’s idiom at once unique and beyond reach, perhaps even untouchable – and this from the creator of such tactile-looking pieces. One way of accepting this invitation to engage with an art that wonders how anything can be engaged with is to ask what it can tell us about the art of others. In this essay, I want to see what the art of Sebald can tell me about the art of Giacometti.

Sprague wrote his outstanding essays many years ago on the meaning of botanical terms used by Plinius, Isidorus, Albertus and Ruellius, no one else had resumed this task, which is essential for the history of botany. Though Albertus explained vegetal structure in terms of the function it fulfils, the methodology used here ignores Physiology and concentrates on Morphology. After discussing the composition of De Vegetabilibus, we deal with organs using the order and division established by Albertus: succus, nodus, radix. venae, stipes, ramus, cortex, flos, folium, fructus, and so on.

Sprague sobre el significado de los términos botánicos empleados por Plinio, Isidoro, Alberto y Ruellius, nadie había reemprendido tan necesaria tarea para la historia de la botánica. Aunque la razón de una estructura vegetal se explica, en San Alberto, por la función que cumple, aquí prescindimos metodológicamente de la fisiología para ceñirnos a la morfología. Tras exponer la composición del De Vegetabilibus, abordamos los distintos órganos de la planta según el orden y la división trazados por él: succus, nodus, radix, venae, stipes, ramus, cortex, flos, fructus, etcétera.

    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.

  13. Evaluation of the ICRU operational magnitudes implantation for the photon radiation at the Angra I and Angra II nuclear power plants

    International Nuclear Information System (INIS)

    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*(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*(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*(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*(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*(10)'s implementation on installations that perform measurements with radiation rate meters on the practice of radiation protection, in order to adopt the H*(10) quantity in our country.

  15. Flow accelerated corrosion programme in Angra nuclear power plants Units 1 and 2

    International Nuclear Information System (INIS)

    Almirante Alvaro Alberto Nuclear Power Plant, referred herein as Angra NPP, comprises two generating units operated by ELETROBRAS Termonuclear S.A. - ELETRONUCLEAR. Unit 1, a Westinghouse designed PWR, operates commercially since 1982 generating 657 MW, while unit 2, designed by Siemens, is a 1350 MW PWR in operation since 2000. Flow Accelerated Corrosion (FAC) programme integrate a set of ageing related programmes established to control ageing effects on equipment and piping in order to ensure their capability to perform their functions during the plant remaining life. The objective of this paper is to describe ELETRONUCLEAR experience in developing and implementing a programme related to Flow Accelerated Corrosion, with focus on piping of the secondary sides of Angra NPP, explaining in detail the current situation for important pipings, and presenting updated results of the FAC control. Accurate inspections are the basis for an effective FAC programme. Wall thickness measurements establish the extent of wear in a given piping, providing data to support FAC trends, and to refine the predictive model. A permanently and clearly identify grid is makes re-inspection possible, at any time, at the same points. Supported by the computational system Comsy, some of its features as FAC potentially susceptible lines identification, wall thinning rates determination, inspection data recording, wear rates analyses, lifetime prediction and inspection scheduling will be showed in detail. This programme has started in 2004, and since this time it was applied in a total of six outages in Angra 1 NPP and three outages in Angra 2 NPP, with a large number of piping elements inspected and analyzed. Some of these results will be showed and discussed in this paper, regarding the potential of Flow Accelerated Corrosion occurrence. (author)

El terrorismo, concepto más bien ilusorio y etéreo que concreto y tangible, y el teatro, donde lo que es y lo que parece ser están nextricablemente interrelacionados, se caracterizan por la inmediatez de la acción y un efecto dramático.

    Full Text Available The essay proposes an analysis of the relationship between text and images in Informe sobre ciegos (1991 by Alberto Breccia. In his obstinate renunciation to unnecessary words, or surplus signs, and by employing graphic devices that convey a "telluric and formless" world, Breccia interprets and illustrates – without making it comprehensible – the self-destructive delirious state of Fernando Vidal, one of the most controversial and fascinating characters in Argentinian literature. In particular, the essay focuses on the conspiracy – at the level of both form and content – and on the graphic (untranslatability of his delirium.

    Full Text Available Alberto Magno ha ofrecido elementos de juicio suficientes que permiten reconstruir una Filosofía Política en su obra teológica y filosófica. Dicha Filosofía Política es solo relativamente autónoma respecto de la Metafísica y de la Teología Sobrenatural, pues aun cuando posee principios propios, un objeto formal propio y un fin también propio, que es el Bien Común Político, los principios, el objeto formal y el fin derivan a su modo, del Ser y del Bien Supremo que son las primeras creaciones de Dios.

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.

    Science.gov (United States)

    Zancan, Lenira; Matida, Álvaro Hideyoshi

    2015-10-01

    The article seeks to reflect on the contribution of Joaquim Alberto Cardoso de Melo (1936-1993) to the field of public health relating his life story and his scientific production with core issues of education and health, present in his time and which remain in debate to this day. His contribution resulted in the production of new meanings for health practices, with the understanding as social and transdisciplinary phenomena. Based on conversations with co-authors and friends and rereading of his texts, it was decided to approach his biography from: (i) his skills and participation in initiatives and practices of preventive medicine and popular education, which fomented the critical analysis of health education; (ii) his presence as an educator in public health courses throughout the country, eliciting the deconstruction of the theories and practices of education and health with managers, students, professionals and teachers; (iii) his availability for transdisciplinary dialogue with the humanities and social sciences in the search for "epistemological sutures" between reason and passion, capable of responding to the dilemmas and challenges of healthcare work. These three trajectories indicate that the performance of "Quincas" must be understood from his restlessness as a health professional and educator, engaged in the production of knowledge and practices related to the complexity of the phenomenon of life.

  19. The power of visual memory: the earliest remembered drawing of Alberto Giacometti, Snow White in Her Coffin.

    Science.gov (United States)

    2008-04-01

    Since the time of Freud, many psychoanalysts have seen screen memories and earliest memories as reflecting underlying dynamics. I propose that an earliest remembered artwork is a highly condensed construction similar to a screen memory. Alberto Giacometti's earliest remembered drawing, of Snow White in Her Coffin, contains clues to the artist's personality and references to childhood experience. Giacometti's memory of the drawing done in childhood is a striking condensation of significant biographical events and psychodynamic conflicts, as well as a marker of important unconscious fantasies. The artist's postwar sculptural style, utilizing gaunt figures, epitomizes the final transformation of the psychological meaning of his earliest remembered drawing. PMID:18512362

    currents for the national nuclear technology policy, but only one of those, the nationalist policy of the admiral Alvaro Alberto, disseminated before the institution creation, had representativity in IPEN, despite of the Program 'Atoms for Peace', which aimed to the arrival of the Institute Master's Cell - the Research Reactor IEA-RI. Obviously, its influence appeared modified by the cultural characteristics which ruled the Institution and braved resisted until the 1990's. From then on, the vector globalization influenced the institute projects. However, the strongest IPEN's culture developed so far did not allow the Institute to direct its goals to the neoliberalism. The lack of governmental financial support on projects performed in the field of the fuel cycle did not unarticulate the researchers. They made an option, inside the new world perspective, pushing ahead the Institution's mission and offering services to the society. This chose was not completely profitable, but allowed that all the capabilities and skills acquired were not lost. The initial dream of nuclear technology development for human well-being and the country progress still survive inside the Institution, although with different goals from its conception. Last, facing the new orientation for the development of S and T in countries such as Brazil, we proposed few alterative ideas of governmental encouragement in order to assist Brazilian society needs.

    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

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. The narrators in his texts find in the narrative of José Donoso, Jorge Edwards and Alfredo Gómez Morel, among others, a corpus of rhetorical figures which allow them to make their deviance explicit in an oblique way; that is, to condense their voluptous desire in the prestigious language of the Chilean Literary Canon. Within this context, this essay explores the quotations of Donoso 's Casa de Campo and El Jardin de al lado, and those quotations of Alfredo Garcia Morel's El río present in Alberto Fuguet's first works (Sobredosis y Mala Onda.

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.

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.

    Alberto Breccia has been one of the fathers of twentieth century graphic narrative. Author of key works as El Eternauta (1969), his forays into the world of literature have been frequent since his début. At the end of his life, Breccia turned into comic the Informe sobre ciegos, central and autonomous chapter of Sobre héroes y tumbas (1961) by Ernesto Sabato. This work will analyse the dialogue that the graphic genius of Breccia establishes with the tormented Sabato’s voice, enriching the mea...

    Alberto Pérez-Gómez’s 1983 Architecture and the Crisis of Modern Science is used here as a vehicle for exploring the behavior of disciplinary boundaries in the context of crisis both historically and theoretically. Responding to his contemporaneous architectural crisis of the 1970s instigated by the rise of positivism, Pérez-Gómez uses Alexandre Koyré’s history of the scientific revolution as a mirror to reflect the historical developments of architectural theory upon it.

    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.

Métodos: El muestreo fue realizado en tres zonas de la microcuenca San Alberto (cuenca alta, media y baja. En los tres sitios fueron colectados macroinvertebrados bentónicos en piedra y arena. Luego se estimaron: el índice biótico andino (IBA, de hábitat fluvial (IHF, de calidad de vegetación de ribera andina (QBRAnd y de estado ecológico (ECOSTRIAND. Se evaluaron parámetros fisicoquímicos, nutrientes y metales en el agua. Resultados: Se registraron un total de 123 taxones de 47 familias (101 taxones en la cuenca alta, 77 en la cuenca media y 55 en la cuenca baja. La mayor abundancia de macroinvertebrados se presentó en la cuenca media. El IBA resultó ser de “muy buena” calidad para la cuenca alta, media y baja, pero al combinarse este índice con el QBR-And, para elaborar el Índice ECOSTRIAND, se observó el estado ecológico de las cuencas alta y media fueron de “muy buena” calidad y de la cuenca baja fue “regular”. El método de muestreo de limpieza de piedras fue el que permitió colectar la mayor cantidad de taxones. Las mejores condiciones de hábitat fluvial, de vegetación ribereña y de estado ecológico, tras la aplicación de los índices IHF, QBR-And y ECOSTRIAND, se encuentran en la cuenca alta. Conclusiones: Los resultados indican que la diferencia de calidad de hábitat ribereño y fluvial así como de conductividad, sólidos disueltos y nitratos influyen negativamente sobre la calidad del agua, y ésta, sobre la comunidad de macroinvertebrados. Las familias reportadas como sensibles a la contaminación (Leptophlebiidae, Oligoneuriidae, Perlidae, Anomalopsychidae, Calamoceratidae, Helicopsychidae, Odontoceridae, Blephariceridae mostraron ser bioindicadores de calidad de agua para la microcuenca.

    Full Text Available El carácter de Alberto Blest Gana como fundador de la novela chilena mal podría ligarlo a la práctica del folletín, aunque registra numerosos títulos publicados en revistas y periódicos. Por lo demás, su filiación como aventajado discípulo de Balzac menos podría propiciar un vínculo con la literatura popular o de masas, como se desarrolló en Francia a mediados del siglo XIX. Y es que el canon literario nacional se construye a partir de una élite intelectual -ilustrada y liberal- que participa de la construcción social de la Nación como la que propiciaba José Victorino Lastarria y el propio Blest Gana -en sus respectivos manifiestos literarios-, en cuya conformación la cultura popular no participa más allá de un “costumbrismo” folklórico, o como un “sabor” local, o como un “pintoresquismo” para solaz de los lectores cultos. En este artículo se indaga en los formantes folletinescos en la narrativa de Blest Gana, recurriendo a las tesis acerca de la literatura popular que han sido postuladas, entre otros, por Eco (1981, 2012; Martín-Barbero (2010, Herlinghaus (2002, Sarlo (1985.

    International Nuclear Information System (INIS)

    The main motivation for the development of training was the need to train agents (opinion makers) with proximity and credibility among the population, to clarify the most frequently asked questions in relation to ionizing radiation, the operation of nuclear power plants, emergency plans and about the possibility of there effects of radiation on the health of inhabitants in regions close to the central Nuclear Almirante Alvaro Alberto - CNAAA. The project has a target audience of 420 agents, 60 of them have already been trained in a pilot project . The results indicate that the topics of training were adequate and the agents have expanded their knowledge. On the other hand, the information passed on to communities by agents, recognized by this population as ' the most reliable people', is of greater credibility and likelihood of success in communicating important issues for the population living in the vicinity of the CNAAA.

  12. Analysis of reactivity insertion accidents in PWR reactors

    International Nuclear Information System (INIS)

    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 UO2 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)

Based on this general reference is possible to evaluate the features in the natural and social environment of Angra dos Reis that probably will obstruct the application of the protective countermeasures to the public. 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)

In his diary he follows with passion and detail the first seven weeks of the Second Spanish Republic. Fr. Risco, more inclined to fundamentalism and traditionalism rather than to the Republic, gives us a vivid, personal and latent view of the situation along the lines of the writings of analysts and journalists of that time. As Jesuit, his biggest concern was the fate of the Church and of the Society of Jesus. Consequently, he stopped writing on the painful 11th May 1931.El jesuita padre Alberto Risco (1873-1937 fue un reconocido autor de textos católicos y cristianos de corte popular y devoto, entre los que podemos destacar Emigración y su muy famoso Compendio de Historia de la Literatura Española. Con el advenimiento de la II República comienza a redactar un diario, en el que sigue con pasión y detalle las siete primeras semanas del nuevo régimen. A pesar de que por temperamento y tradición Risco se muestra más inclinado al fundamentalismo y al tradicionalismo que a los nuevos aíres de la República, nos ofrece en el texto que ahora presentamos una viva, personal e inspirada visión no muy distinta a la de otros escritores y analistas de su tiempo. Como jesuita, se sintió muy afectado por el futuro de la Iglesia y de la Compañía de Jesús. En consecuencia, presta especial atención a los dolorosos sucesos del 11 de mayo de 1931.

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.

  5. Evaluation of protection measurements for rural environments

    International Nuclear Information System (INIS)

    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 137Cs, 131I and 90Sr 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

  10. Environmental sceneries in NPP: use of the geographical information system for integration of the local meteorology with other environmental factors

    International Nuclear Information System (INIS)

    The Central Nuclear Almirante Alvaro Alberto is located in an extreme complex region, in terms of meteorological topographical and geographical aspects. Several environmental studies have been carried out since the construction of the unit I. The main scope of this thesis is the intersection of the existing relevant information to evaluate in detail the environmental impact of this particular installation. To reach this objective some meteorological scenarios were established, based on statistics analysis from data collected by installation's meteorological system and from data obtained in local atmospherics experiments. These summaries were submitted to a specific computer code to calculate the dispersion factors considering typical annual releases of the Xe-133 and I-131 from unit I. These factors describe the capacity of the local atmosphere to transport and to dilute a contaminant up to a distance of 15 Km far the from the realizing point. Finally, a Geographic Information System has been used to integrate all the relevant information including population and land covers to produce a series of output maps; where the degree of impact under the various scenarios, are identified by wind sector and respective distance from the realizing point. Conclusions and recommendations are mainly presented in terms of emergency planning. (author)

    1995-02-01

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

  3. Radionuclides determination in the Sargassum algae located in the Saco de Piraquara de Fora - Angra dos Reis - Rio de Janeiro - Brazil

    International Nuclear Information System (INIS)

    The main purpose of the Environmental Monitoring Laboratory, in the Mambucaba Residential Site is to control all environment around Almirante Alvaro Alberto Nuclear Power Station (AAANPS) in order to check its operational influence on the local ecosystem. Angra I Nuclear Power Plant usually discharges liquid waste from the Treatment System (waste and recycle evaporators). Before the water is discharged into the sea, it is chemically and radiochemically and analysed to verify if dissolved contaminants are in agreement with the specifications established by the Fundacao Estadual de Engenharia de Meio Ambiente (FEEMA) for the chemical parameters and by the Comissao Nacional de Energia Nuclear (CNEN) for radiochemical parameters. Such radioactive contaminants are 58 Co, 60 Co and 54 Mn, which are activated corrosion products from structural materials of the primary system and 134 Cs and 137 Cs, fission products produced by the nuclear reactor during its operation. To measure and control the possible discharge of these radionuclides into the sea and their incorporation to the marine organisms, it was created the Environmental Radiological Monitoring Special Program (ERMSP). The purpose of this program is to control the absorption of the radionuclides 58 Co, 60 Co, 54 Mn, 134 Cs and 137 Cs in algae of the genus Sargassum located in the surroundings the discharge of the liquid effluents of the genus Sargassum located in the surroundings the discharge of the liquid effluents of the Plant in Saco de Piraquara de Fora. The algae are considered excellent bioindicators because they are fixed on the rocks, being totally dependent on the water quality where they live, being being as easy target to incorporate and to detect those radionuclides. The algae are collected bimestrally and analysed by the Laboratory. This work presents the sampling process, the preparation, the sampling process, the preparation, the analysis of the radionuclides and the results obtained. (author)

    International Nuclear Information System (INIS)

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

  15. Nuclear power

    International Nuclear Information System (INIS)

    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

  17. Nuclear forensics

    International Nuclear Information System (INIS)

    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.

  18. Nuclear energy and nuclear weapons

    International Nuclear Information System (INIS)

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

    Nuclear power has been seen as an answer to the energy problems of the Third World and Third World markets have been seen as an answer to the problems of the nuclear power industry. For some years during the 1970s both views seemed tenable. This paper examines the progress and setbacks of nuclear power in developing countries. In concentrates mainly on the four countries with real nuclear power commitments (as opposed to all-but-abandoned ambitions) - South Korea and Taiwan, where the interest has been mainly in obtaining cheaper and reliable electricity supplies, and Argentina and India, where the main interest has been in developing indigenous nuclear technological capabilities. A number of possibilities are examined which could influence future nuclear ordering, including smaller reactors to suit Third World electricity grids and a possible way round the constraint of large external debts.

    Neufeld, Kristi L

    2009-01-01

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

    The problem of core-collapse supernovae is used to illustrate the many connections between nuclear astrophysics and the problems nuclear physicists study in terrestrial laboratories. Efforts to better understand the collapse and mantle ejection are also motivated by a variety of interdisciplinary issues in nuclear, particle, and astrophysics, including galactic chemical evolution, neutrino masses and mixing, and stellar cooling by the emission of new particles. The current status of theory and observations is summarized

  9. Nuclear Law

    International Nuclear Information System (INIS)

    This book on nuclear law is the first of a series of analytical studies to be published by the French Energy Commission (CEA) concerning all the various nuclear activities. It describes national and international legislation applicable in France covering the following main sectors: the licensing procedure for nuclear installations, the law of the sea and nuclear law, the legal system governing radioisotopes, the transport of radioactive materials, third party liability and insurance and radiation protection. In each chapter, the overall analysis is supplemented by the relevant regulatory texts and by organisation charts in annex. (NEA)

  10. Nuclear critics and nuclear economics

    International Nuclear Information System (INIS)

    The ongoing nuclear debate is given to attacks on the economics of nuclear power that ignore the actual performance of operating plants. Today, almost every existing nuclear power plant has provided significant savings to the customers it supplies. (The exceptions to this, while important, are not being hidden. Instead, the problem plants, Palisades and Browns Ferry in the main, as well as all our nuclear units, are being studied and carefully monitored with the view to improving performance. The fact remains that nuclear units ordered today are expected to provide more economical energy in almost all parts of the nation than any other available steam-electric alternative.) Despite extensive data to the contrary on file with regulatory commissions, both state and Federal, publications on nuclear power economics by adversary groups appear to have gained far more attention that the actual record. But, during 1977, nuclear generation accounted for about 12 percent of the nation's production of electricity, exceeding the output of hydroelectric power for the first time in history. For Northeast Utilities, where for the first nine months of 1977 63 percent of the electricity was nuclear, every nuclear kWh meant a direct reduction in imported oil. U.S. government figures for the first eight months of 1977 show that nuclear generation totaled 160 billion net kWh, equivalent to about 300 million barrels of oil, almost a million barrels per day. Obviously nuclear capacity that displaces that much oil is advantageous, both for the utility and for the nation. The U.S. could build a lot of generating capacity (nuclear and coal) and do a lot of research (solar, fusion, breeder reactors) with even a fraction of the $40 billion now going to the oil-exporting countries each year

    This document presents the fulfilling of the Brazilian obligations under the Convention on Nuclear Safety. The Chapter 2 of the document contains some details about the existing Brazilian nuclear installations. Also, safety improvements at Angra 1 and aspects of Angra 2 and 3 are reported

  12. Nuclear violence

    International Nuclear Information System (INIS)

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

  15. Nuclear measurements

    International Nuclear Information System (INIS)

    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

  16. Nuclear energy

    International Nuclear Information System (INIS)

    This book provides the man in the street with a fair presentation of nuclear energy and can help him to build his own opinion about this much debated question. The first chapter defines what is involved in the hazy term of energy. The second chapter explains how a nuclear power plant operates. The chapters 3 to 6 give a good grounding in basic physics to understand radioactivity and the different processes that occur in a nuclear reactor. The chapters 7 and 8 present the different reactor types and the complete fuel cycle from uranium ore extraction to radioactive waste storage. The last chapter is dedicated to the pros and cons of nuclear energy, this chapter includes a presentation of the organization of nuclear safety in France. (A.C.)

  17. Nuclear Safety

    International Nuclear Information System (INIS)

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

  18. Nuclear supervision

    International Nuclear Information System (INIS)

    State supervision of economic activities - economic supervision - takes place in the most varied fields. The study initially pursues the question of whether nuclear supervision has a special position, i.e. whether there are significant legal or factual differences to other fields of industrial administrative law. To this end, common features of economic supervision with regard to subject, function and instruments are developed. Subsequently nuclear supervision, in its function as a part of economic supervision, is examined with regard to similarities and peculiarities. The interactions between planning permission and operational supervision under nuclear law are illustrated, and thus the position of Art. 19 of the German Nuclear Energy Act defined within the broader framework of nuclear control. The second part of the work is concerned with individual questions relating to Art. 19 of the above Act. (orig./HSCH)

  19. Nuclear haematology

    International Nuclear Information System (INIS)

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

  20. Nuclear medicine

    International Nuclear Information System (INIS)

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

  1. Nuclear power and nuclear insurance

    International Nuclear Information System (INIS)

    Fanned by the Chernobyl reactor accident the discussion about the safety and insurability of nuclear power plants has also been affecting the insurance companies. The related analyses of the safety concepts of German nuclear power plants have been confirming the companies' risk philosophy of maintaining the insurability of nuclear power plants either meeting German safety standards or equivalent safety standards. Apart from the technical evaluation of the safety of nuclear power plants the fundamental discussion about the pros and cons of nuclear power has also been stressing the damages and liability problem. The particular relevance of possible considerable transfrontier contaminations clearly reveals the urgency of establishing internationally standardized reactor accident liability regulations. (orig./HP)

  2. Nuclear Hostages

    International Nuclear Information System (INIS)

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

  5. Study of the dispersion of radionuclides in the Ilha Grande Bay - RJ

    International Nuclear Information System (INIS)

    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 3H results (1 :16) and those reported by Franklin (1 :20) can be seen as relevant. The post-1965 137Cs 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 223Ra and 224Ra distribution pathways result in diffusion coefficients ranging from 20,12 ± 3,81 - 21,07 ± 3,91 km2.d-1 to a 228Ra offshore flux and time of residence of, respectively, 3,18 ± 1,01 x 108 Bq.d-1 and 25,35 ± 0,45 days. On the other hand, an uppermost advection process provided 228Ra offshore flux and time of residence of, respectively, 2,26 ± 0,424 x 108Bq.d-1 and 13,08 ± 0,21 days. (author)

  6. Nuclear waste

    International Nuclear Information System (INIS)

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

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

  8. Nuclear insurance

    International Nuclear Information System (INIS)

    The DKVG (German nuclear power plant insurance association) has 104 member insurance companies, all registered in the Federal Republic of Germany. In 1991, the inland portfolio of the DKVG covered 21 contracts in the property insurance sector, and 22 contracts in the nuclear liability sector. There will be no new nuclear power plants to be insured in the Federal Republic of Germany within the foreseeable future. The home business in 1991 remained claim-free, as in the year before. The overall loss ratio went down to 2.9 per cent, after it had been 15.4 per cent in 1989. This very low loss ratio of 2.9 per cent should not deviate from the fact that nuclear insurers always have to reckon with a substantial damage. Such an event at present would cost them a maximum gross sum of DM 1.7 million, which would mean DM 730 million on account of DKVG. (orig./HSCH)

    International Nuclear Information System (INIS)

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

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

  5. Nuclear astrophysics

    International Nuclear Information System (INIS)

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

  11. Nuclear power

    International Nuclear Information System (INIS)

    After three decades of commercial development, nuclear power has failed to fulfil its promise. Why, and what does that failure imply for the future of energy policy? One reason for nuclear power's slow growth is that rich countries have repeatedly found they needed less electricity than they had forecast. Part of the problem is, as it always has been, public unease. Worries about safety affect costs. They make it harder and more time-consuming to find sites for new plants or for storing waste. Complex safety devices mean complex plants, which are more expensive to build (and to relicense when they grow old). The true cost of nuclear power is hard to calculate. However nuclear power now seems to be less economically favourable when compared with its main rival, coal. The only hope for nuclear power is that, apart from hydropower, it is the only commercial alternative to fossil fuels. Concerns over carbon dioxide emissions may tip the balance in nuclear's favour.

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

  13. Nuclear fuel

    International Nuclear Information System (INIS)

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

  14. Nuclear watershed

    International Nuclear Information System (INIS)

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

  19. Nuclear suppression

    International Nuclear Information System (INIS)

    This article draws attention to a number of cases where it seems that scientists and technologists have been penalized in various ways for having views opposed to those of the nuclear industry. Attempts to encourage the general public to understand nuclear issues have also been discouraged, nuclear knowledge being kept as the preserve of the experts and policy makers, especially in the military applications of nuclear power. It may be that publications are suppressed or careers are destroyed. One example highlighted in the article is of Dhirendra Shama, a critic of India's nuclear policy, who was suddenly transferred from the Centre of Studies in Science Policy at his University to the School of Languages. Other examples are given from other countries - Australia, Britain, Canada, Federal Republic of Germany, India, Japan, New Zealand, Soviet Union, Sweden and the United States of America. The main 'crime' of those victimised is not in having critical views, but in alerting the general public to those critical view and ideas. (UK)

  20. Nuclear recession

    International Nuclear Information System (INIS)

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

  1. Nuclear scales

    Energy Technology Data Exchange (ETDEWEB)

    Friar, J.L.

    1998-12-01

    Nuclear scales are discussed from the nuclear physics viewpoint. The conventional nuclear potential is characterized as a black box that interpolates nucleon-nucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longer-range parts of the NN force (e.g., OPEP, TPEP, the {pi}-{gamma} force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted.

  2. Nuclear Law

    International Nuclear Information System (INIS)

    We find in this report two studies, one about the compensation regimes applicable to radiation workers in OECD countries, the second one about Tokai-mura accident (Japan): third party liability and compensation aspects. Then, come the case law and administrative decisions, national legislative and regulation activities, international regulatory activities, bilateral agreements, multilateral agreements. Among these different parts are to notice: judgement in the public civil action concerning the Goiania radiological accident (2000,Brazil), judgement of the Council of State confirming the definitive shut-down of Superphenix (2000, France), decision relative to the DOE 's obligation to accept spent nuclear fuel and high level radioactive wastes (HLRW) from nuclear power plants (NPPs) (2000, Usa), decision concerning the construction of a permanent repository for spent nuclear fuel (2000, Finland). (N.C.)

  3. Nuclear materials

    International Nuclear Information System (INIS)

    In 1996, 39 inspections of nuclear materials were performed, 22 of them performed in co-operation with IAEA inspectors. The main content of common inspections with IAEA was the inspection of both fresh and spent fuel in Bohunice NPPs and Mochovce NPPs. During 1996 there were 420 spent fuel assemblies transported from the V-1 and V-2 NPPs units to the interim spent fuel storage and 396 spent fuel assemblies were transported to the Dukovany NPP. Current state of stored spent fuel in the interim spent fuel storage is 4656 fuel assemblies, 4050 of them are Bohunice NPPs assemblies and 606 of them are fuel assemblies which belong to Dukovany NPP. There are 128 spent fuel assemblies stored in A-1 NPP, which are placed in cases of the long-term storage. Inspections of fresh fuel storage in the V-1, V-2 and Mochovce NPPs were performed, as well as spent fuel inspections in the A-1 NPP and in the interim spent fuel storage in Bohunice. From the outcomes of inspections resulted, that the limits and conditions, operating procedures and conditions of nuclear safety were not violated in any ease. There was no extraordinary event at above mentioned equipment during the 1996 and the equipment was reliably operated. NRA SR performed during 1996 eight inspections focused on safety protection of nuclear equipment and nuclear materials, and no significant deficiencies, which could resulted in extraordinary events or violation of nuclear safety were found out. Safety of transportation of fresh fuel, spent fuels, and other materials is discussed. NRA SR performed inspection focused on checking transportation readiness each transportation of the spent nuclear fuel. Serious deficiencies were not found out. Suggested system for treatment of radioactive materials caught at illegal trade is described. An attempt to export 3 radioactive sources in consignment of iron scrap to Italy came about in 1996. The NRA SR continued in co-operation with IAEA on updating IAEA database to illegal

    This extract from the House of Commons Hansard publication for Wednesday 12th July 1995 considers the current debate on the desirability or otherwise of disposing of low level radioactive waste in landfill sites. It covers wastes generated both by the nuclear industry and by medical processes in local hospitals, and the transport of such waste from source to disposal site. The questions raised lead to a debate about plans to sell off commercially desirable aspects of the nuclear electric generation industry while leaving the costs associated with decommissioning of Magnox reactors as a liability on the public purse.

  10. Nuclear percolation

    International Nuclear Information System (INIS)

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

  11. Nuclear safety

    International Nuclear Information System (INIS)

    GAO reviewed DOE's efforts to restart three nuclear reactors at its Savannah River site in South Carolina. Restarting the reactors, which have not been in operating since 1986, is a top priority at DOE because the reactors are the nation's only production source of tritium, a radioactive gas used in nuclear weapons. This report describes factors that might delay restarting the reactors and what the operating contractor is doing to bring about a better attitude toward safety among its personnel and the Savannah River site. This report also contains information on safety attitude problems at other DOE facilities and with DOE employees

  15. Nuclear reactions

    International Nuclear Information System (INIS)

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

    Nuclear medicine utilizes radioisotopes to diagnose and in some cases treat disease. Modern instruments can image their accumulation in an organ and provide quantitative data when indicated. The strength of these procedures is in the unique physiologic information they provide, rather than the presentation of precise anatomic detail.

  17. Nuclear waste

    International Nuclear Information System (INIS)

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

    2015-01-01

    It is a great honor to receive the 2014 Nuclear Fusion Prize, here at the 25th IAEA Fusion Energy Conference. 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

By using reinsurance capacities of the other pools at present property insurance amounts to 1.5 billion DM and liability insurance to 200 million DM. In 1991 the damage charges on account of DKV amounted to 3.1 (1990 : 4.3) million DM. From these 0.6 million DM are apportioned to payments and 2.5 million DM to reserves. One large damage would cost a maximum gross sum of 2.2 billion DM property and liability insurance; on account of DKVG 750 million DM. (orig./HSCH)

  9. Nuclear waste

    International Nuclear Information System (INIS)

    Radioactive waste at U.S. nuclear power plants is mounting at a rate of more than 2,000 metric tons a year. Yet the Department of Energy (DOE) does not expect a geologic repository to be available before 2010. In response to concerns about how best to store the waste until a repository is available, GAO reviewed the alternatives of continued storage at utilities' reactor sites or transferring waste to a monitored retrievable storage facility. This paper assesses the likelihood of a monitored retrievable storage facility operating by 1990, legal implications if DOE is unable to take delivery of wastes in 1998, propriety of using the Nuclear Waste Fund from which DOE's waste program costs are paid to pay utilities for on-site storage capacity added after 1998, the ability of utilities to store their waste on-site until a repository is operating, and relative costs and safety of the two storage alternatives

  10. Nuclear nonproliferation

    International Nuclear Information System (INIS)

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

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

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

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

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

    This book discusses the GAO's work on the Department of Energy's (DOE) Waste Isolation Pilot Plant (WIPP). As is known, DOE is seeking legislation permanently withdrawing the WIPP site, located on federal land near Carlsbad, New Mexico, from public use. Because DOE wants to begin storing a limited amount of nuclear waste in WIPP for tests, action on land withdrawal, either through legislation or administrative action by the Secretary of the Interior, is necessary to authorize such storage

    Nuclear energy can play a role in carbon free production of electrical energy, thus making it interesting for tomorrow’s energy mix. However, several issues have to be addressed. In fission technology, the design of so-called fourth generation reactors show great promise, in particular in addressing materials efficiency and safety issues. If successfully developed, such reactors may have an important and sustainable part in future energy production. Working fusion reactors may be even more ma...

  5. Nuclear astrophysics: An application of nuclear physics

    International Nuclear Information System (INIS)

    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 14N(p,r)15O reaction rate in the determination of the age of globular clusters will be discussed in details

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

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

  8. Nuclear waste

    International Nuclear Information System (INIS)

    The Department of Energy plans to award a contract to Bechtel Systems Management, Inc. to manage and operate the federal government's nuclear waste repository. The proposed management and operating contract is likely to substantially affect program operations and costs. This paper reports on a GAO report. A major concern is the degree to which the selected contractor might replace, or possibly duplicate, the efforts now being carried out by DOE's current contractors. It is questionable whether the contract will result in a more efficient and effective program. DOE officials have had to divert their attention from program operations to develop the contract proposal and participate in legal proceedings related to a bid protest. GAO and the DOE inspector general have reported on problems and issues involving DOE's administration of management and operating contracts, including some companies which participate in the nuclear waste program. Many of the resulting recommendations have yet to be implemented. Implementation of these recommendations could help ensure that the nuclear waste program is operated in a more cost-effective manner

  9. Nuclear waste

    International Nuclear Information System (INIS)

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

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

  17. Nuclear undertakers

    International Nuclear Information System (INIS)

    The Shippingport Atomic Power Station, the first commercial nuclear central electric-generating station in the US, will soon be taken apart and buried in a process known as decommissioning. Beginning in the spring of 1985, and expected to last four years, the process will be closely watched by both the nuclear industry and its critics. A small crew has just finished removing the last fuel assemblies from the reactor's nuclear core; however, the pressure-vessel walls remain intensely radioactive. The author outlines the radiation protective measures that will be used as the workers cut and saw to disassemble the 21 miles of piping inside the plant - e.g., building plastic enclosures around certain work areas to trap radioactive dust and working behind shielding as positioned saws do the cutting. Also, any radioactive concrete in the plant will be removed, again using the best radiation-protective measures. Once the decommissioning team works its way in the heart of the reactor, the pressure vessel - a steel cylinder 35 ft high and 10 ft across with walls 8 inches thick - plans call for erecting a tower above and pouring concrete into the cavity around the vessel. The 770-ton steel and concrete package will then be hoisted in one piece, placed on a heavy-duty transporter and hauled to a barge on the Ohio River, eventually following a water route to the Hanford, Washington energy reservation; there it will join some other 120 truckloads of other radioactive wastes from its plant for burial. Even if this is successfully accomplished as planned and at the $80 million estimate, critics point out that decommissioning the much larger plants will be much more complex and costly - that Shippingport is far from an analogous situation

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

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

  15. Nuclear regulation

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

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

    This article presents a brief history of nuclear medicine in France and describes the recent developments and equipment of the 3 techniques most used in hospital nuclear departments: 1) gamma-camera, 2) single photon emission computed tomography (SPECT), and 3) positron emission computed tomography (PECT). Concerning gamma-camera, a new design is being studied in a collaboration between the Saint-Gobain company and the LETI (a laboratory of Cea). In this innovative design the scintillator and the photomultiplier are replaced by a matrix of semi-conductor detectors based on CdZnTe crystal combined with an adequate electronic equipment. Concerning SPECT, many different techniques and equipment are used. Most improvements handle with the reduction of the survey time for the patient by using several detectors set on a ring around the patient. Concerning PECT, the developments follow 2 parallel ways: first the use of better scintillating materials for detecting 511 KeV photons (BGO: bismuth germanate, BaF2, LSO: lutetium orthosilicate, or GSO: gadolinium orthosilicate), and secondly the use of beta+ decay radionuclides that are more easily integrated in molecules similar to those present in the humane metabolism (18F through the fluorodeoxyglucose molecule).

  18. Nuclear regulation

    International Nuclear Information System (INIS)

    As of November 1988, seven nuclear plants were shut down to correct safety and/or management problems. However, the Nuclear Regulatory Commission does not have criteria that specify the actions that must be taken before a plant can restart operations. In November 1988, NRC's Executive Director for Operations issued staff guidelines, but the guidelines do not go far enough. The guidelines do not discuss public participation, independent review, or utility actions prior to restarting a plant. This paper presents some recommendations made in a GAO report. Among these recommendations are the following: NRC needs to establish criteria to ensure that a consistent process is used to assess the readiness of any plant that has been shut down for management and/or safety problems. The criteria should describe both NRC and utility actions that must be taken before allowing a plant to restart operations. The criteria should be flexible enough to allow NRC to add requirements on a plant-by-plant basis giving consideration to overall design, personnel, and management

A question is put that if this kind of protection carries on, won't there always be a minority of the public who will find nuclear power socially, psychologically and politically unacceptable

  20. Efficacy of nuclear forensics

    International Nuclear Information System (INIS)

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

  8. Nuclear insurance

    International Nuclear Information System (INIS)

    The German Nuclear Power Plant Insurance (DKVG) Association was able to increase its net capacity in property insurance to 637 million marks in 1993 (1992: 589 million). The reinsurance capacity of the other pools included, the total amount covered now amounts to 2 billion marks in property incurance and 200 million marks in liability incurance. As in the year before the pool can reckon with a stable gross premium yield around 175 million marks. The revival of the US dollar has played a decisive role in this development. In 1993 in the domestic market, the DKVG offered policies for 22 types of property risk and 43 types to third-party risk, operating with a gross target premium of 65 million marks and 16 million marks, respectively. The DKVG also participated in 540 foreign insurance contracts. (orig./HSCH)

    International Nuclear Information System (INIS)

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

    Fuel is one of the essential components in a reactor. It is within that fuel that nuclear reactions take place, i.e. fission of heavy atoms, uranium and plutonium. Fuel is at the core of the reactor, but equally at the core of the nuclear system as a whole. Fuel design and properties influence reactor behavior, performance, and safety. Even though it only accounts for a small part of the cost per kilowatt-hour of power provided by current nuclear power plants, good utilization of fuel is a major economic issue. Major advances have yet to be achieved, to ensure longer in-reactor dwell-time, thus enabling fuel to yield more energy; and improve ruggedness. Aside from economics, and safety, such strategic issues as use of plutonium, conservation of resources, and nuclear waste management have to be addressed, and true technological challenges arise. This Monograph surveys current knowledge regarding in-reactor behavior, operating limits, and avenues for R and D. It also provides illustrations of ongoing research work, setting out a few noteworthy results recently achieved. Content: 1 - Introduction; 2 - Water reactor fuel: What are the features of water reactor fuel? 9 (What is the purpose of a nuclear fuel?, Ceramic fuel, Fuel rods, PWR fuel assemblies, BWR fuel assemblies); Fabrication of water reactor fuels (Fabrication of UO{sub 2} pellets, Fabrication of MOX (mixed uranium-plutonium oxide) pellets, Fabrication of claddings); In-reactor behavior of UO{sub 2} and MOX fuels (Irradiation conditions during nominal operation, Heat generation, and removal, The processes involved at the start of irradiation, Fission gas behavior, Microstructural changes); Water reactor fuel behavior in loss of tightness conditions (Cladding, the first containment barrier, Causes of failure, Consequences of a failure); Microscopic morphology of fuel ceramic and its evolution under irradiation; Migration and localization of fission products in UOX and MOX matrices (The ceramic under

    It is generally considered that an atomic nucleus is always compact. Based on the isospin-dependent Boltzmann nuclear transport model, here I show that large block nuclear matter or excited nuclear matter may both be hollow. And the size of inner bubble in these matter is affected by the charge number of nuclear matter. Existence of hollow nuclear matter may have many implications in nuclear or atomic physics or astrophysics as well as some practical applications.

  11. 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.

  12. Nuclear husbandry functions

    International Nuclear Information System (INIS)

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

  17. Nuclear criticality safety at global nuclear fuel

    International Nuclear Information System (INIS)

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

  19. The importance of the human factor in a physical protection system

    International Nuclear Information System (INIS)

    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

  20. Nuclear regulation

    International Nuclear Information System (INIS)

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

  2. Nuclear waste

    International Nuclear Information System (INIS)

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

  3. Sunken nuclear submarines

    International Nuclear Information System (INIS)

    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

  4. Nuclear policy of India

    International Nuclear Information System (INIS)

    This paper analyses the Indian nuclear policy, doctrine, strategy and posture, clarifying the elastic concept of 'credible minimum deterrence' at the center of the country's approach to nuclear security. The Indian nuclear policy and thinking against the theories of nuclear war and strategic deterrence, nuclear escalation, and nuclear coercion, offers a strong theoretical grounding for the Indian approach to nuclear war and peace, nuclear deterrence and escalation, nonproliferation and disarmament, and to limited war in a nuclearized environment. On May 11 and 13, 1998, India tested a total of five nuclear devices in the desert stands at Pokhran. The tests caught the Indian public and the world by surprise. On other issues, while there were palpable differences of opinion in the country, the nature of the differences became progressively clearer, so that it is possible to delineate the major contending schools of thought on the future of Indian nuclear policy.

  5. Nuclear knowledge management

    International Nuclear Information System (INIS)

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

  6. IAEA and nuclear forensics

    International Nuclear Information System (INIS)

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

  7. Nuclear disarmament and peaceful nuclear technology

    International Nuclear Information System (INIS)

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

  10. Nuclear reactor

    International Nuclear Information System (INIS)

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

  11. Nuclear power, nuclear weapons, and international stability

    International Nuclear Information System (INIS)

    The National Energy Plan included as one of its key components a revision of this country's long-standing policy on the development of civilian nuclear power. The proposed change, which would have the effect of curtailing certain aspects of the U.S. nuclear-power program and of placing new restrictions on the export of nuclear materials, equipment, and services, was based explicitly on the assumption that there is a positive correlation between the worldwide spread of nuclear-power plants and their associated technology on the one hand, and the proliferation of nuclear weapons and the risk of nuclear war on the other. The authors advance here the heretical proposition that the supposed correlation may go the other way, and that the recent actions and statements of the U.S. Government have taken little account of this possibility. In brief, they suggest that if the U.S. were to forgo the option of expanding its nuclear-energy supply, the global scarcity of usable energy resources would force other countries to opt even more vigorously for nuclear power and, moreover, to do so in ways that would tend to be internationally destabilizing. Thus, actions taken with the earnest intent of strengthening world security would ultimately weaken it. They believe further that any policy that seeks to divide the world into nuclear ''have'' and ''have not'' nations by attempting to lock up the assets of nuclear technologywill lead to neither a just nor a sustainable world society but to the inverse. In any event the technology itself probably cannot be effectively contained. They believe that the dangers of nuclear proliferation can be eliminated only by building a society that sees no advantage in having nuclear weapons in the first place. Accordingly, they view the problem of the proliferation of nuclear weapons as an important issue not just in the context of nuclear power but in a larger context

The texts of the nuclear laws in Uruguay are reproduced, and several aspects on nuclear energy are discussed

  13. Nuclear energy and security

    International Nuclear Information System (INIS)

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

  14. Nuclear literacy - Hungarian experiences

    International Nuclear Information System (INIS)

    The operation of nuclear power plants and the related environmental sentiments make basic nuclear education to a precondition of modern democratic decision making. Nuclear chapters of the curriculum used to treat the topics in historical and descriptive, thus less convincing way.

  20. IAEA nuclear security program

    International Nuclear Information System (INIS)

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

    Lucki, Natasha C.; Sewer, Marion B.

    2014-01-01

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

  6. Potential for nuclear terrorism

    International Nuclear Information System (INIS)

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

    Nuclear power has long been controversial because of concerns about nuclear accidents, storage of spent fuel, and how the spread of nuclear power might raise risks of the proliferation of nuclear weapons. These concerns are real and important. However, emphasizing these concerns implicitly suggests that unless these issues are taken into account, nuclear power would otherwise be cost effective compared to other forms of electricity generation. This implication is unwarranted. Throughout the h...

  11. What is nuclear forensics?

    International Nuclear Information System (INIS)

    Nuclear forensics is the investigation of nuclear materials to find evidence for example the source, the trafficking, and the enrichment of the material. The material can be recovered from various sources including dust from the vicinity of a nuclear facility, or from the radioactive debris following a nuclear explosion. Results of nuclear forensic testing are used by different organizations to make decisions. The information is typically combined with other sources of information such as law enforcement and intelligence information

  12. Nuclear terrorism and reality

    International Nuclear Information System (INIS)

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

  15. Nuclear Education in France

    International Nuclear Information System (INIS)

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

  16. Global nuclear security engagement

    International Nuclear Information System (INIS)

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

    We first define a series of NN interaction models ranging from very simple to fully realistic. We then present Green's function Monte Carlo calculations of light nuclei to show how nuclear spectra evolve as the nuclear forces are made increasingly sophisticated. We find that the absence of stable five- and eight-body nuclei depends crucially on the spin, isospin, and tensor components of the nuclear force.

  3. Nuclear disarmament or survival of nuclear arms?

    International Nuclear Information System (INIS)

    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..

  4. Nuclear information access system

    International Nuclear Information System (INIS)

    The energy supply in the countries, which have abundant energy resources, may not be affected by accepting the assertion of anti-nuclear and environment groups. Anti-nuclear movements in the countries which have little energy resources may cause serious problem in securing energy supply. Especially, it is distinct in Korea because she heavily depends on nuclear energy in electricity supply(nuclear share in total electricity supply is about 40%).The cause of social trouble surrounding nuclear energy is being involved with various circumstances. However, it is very important that we are not aware of the importance of information access and prepared for such a situation from the early stage of nuclear energy's development. In those matter, this paper analyzes the contents of nuclear information access system in France and Japan which have dynamic nuclear development program and presents the direction of the nuclear access regime through comparing Korean status and referring to progresses of the regime

    2010-07-01

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

  13. The Nuclear Symmetry Energy

    OpenAIRE

    Baldo, M.; Burgio, G.F.

    2016-01-01

    The nuclear symmetry energy characterizes the variation of the binding energy as the neutron to proton ratio of a nuclear system is varied. This is one of the most important features of nuclear physics in general, since it is just related to the two component nature of the nuclear systems. As such it is one of the most relevant physical parameters that affect the physics of many phenomena and nuclear processes. This review paper presents a survey of the role and relevance of the nuclear symme...

  14. Risks and nuclear insurance

    International Nuclear Information System (INIS)

    When analysing the nuclear insurance market, three elements must be taken into account: the nuclear operator's liability is regulated by national laws and/or international Conventions, such operators pay large premiums to insure their nuclear installations against property damage and finally, the nuclear insurance market is made up of pools and is mainly a monopoly. This report describes the different types of insurance coverage, the system governing nuclear third party liability under the Paris Convention and the Brussels Supplementary Convention and several national laws in that field. The last part of the report deals with liability and insurance aspects of international transport of nuclear materials

  18. Persistency of atmospheric diffusion conditions in Angra dos Reis - Brazil

    International Nuclear Information System (INIS)

    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)

    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

To enhance the implementation of newly issued nuclear safety regulations, the NNSA conducted seven times of propagating activities in relation to the regulations for nuclear pressure retaining components and research reactors design and operating in 1995

  2. India's nuclear doctrine

    International Nuclear Information System (INIS)

    At a time when the world is rife with speculation about India's nuclear programme, India's nuclear doctrine presents an informed and lucid account of the country's nuclear policy since 1948, through Pokhran I and Pokhran II. The book traces the origin and proliferation of nuclear weapons in the world beginning with the first test by USA in 1945, and the eventually cataclysmic use of the atom bomb over Hiroshima and Nagasaki. The author argues effectively that while remaining committed to its advocacy of complete nuclear disarmament, India is only too aware of its need to maintain nuclear deterrence so long as weapons of this nature remain with the other nuclear powers. World peace, however, is lndia's priority and the author makes a dynamic case for the claim that the weapons of nuclear India are no threat to international peace and security

  3. The ultimate nuclear accident

    International Nuclear Information System (INIS)

    The estimated energy equivalent of Chernobyl explosion was the 1/150 th of the explosive energy equivalent of atomic bomb dropped on Hiroshima; while the devastation that could be caused by the world's stock pile of nuclear weapons, could be equivalent to 160 millions of Chernobyl-like incidents. As known, the number of nuclear weapons is over 50,000 and 2000 nuclear weapons are sufficient to destroy the world. The Three Mile Island and Chernobyl accidents have been blamed on human factors but also the human element, particularly in the form of psychological stresses on those operating the nuclear weapons, could accidentally bring the world to a nuclear catastrophe. This opinion is encouraged by the London's Sunday Times magazine which gave a graphic description of life inside a nuclear submarine. So, to speak of nuclear reactor accidents and not of nuclear weapons is false security. (author)

  4. Nuclear disarmament verification

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-31

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

  10. Nuclear power economics

    International Nuclear Information System (INIS)

    As a petroleum substitute, the nuclear power in Japan possesses the following four features. (1) Stability in supply: The import of nuclear fuel resources is performed from politically stable advanced countries and in long-term contracts. And, nuclear power can be of semi-domestic energy source due to the nuclear fuel cycle. (2) Low cost of nuclear power generation. (3) Contribution of nuclear power technology to other advanced industries. (4) Favorable effects of nuclear power siting upon the region concerned, such as labor employment and social welfare. Electricity charges are high in Japan, as compared with those in the United States and others where coal and water power are relatively abundant. For Japan without such natural resources, nuclear energy is important in lowering the power rates. (Mori, K.)

    Orphan nuclear bodies are defined as nonchromatin nuclear compartments that have been less well studied compared with other well-characterized structures in the nucleus. Nuclear bodies have traditionally been thought of as uniform distinct entities depending on the protein “markers” they contain. However, it is becoming increasingly apparent that nuclear bodies enriched in different sets of transcriptional regulators share a link to the ubiquitin-proteasome and SUMO-conjugation pathways. An e...

  6. Prevention of nuclear war

    International Nuclear Information System (INIS)

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

  17. Nuclear liability insurance

    International Nuclear Information System (INIS)

    Nuclear liability insurance, which exists in some countries, is provided by pools, which are groups of insurance companies that have voluntarily combined to share the insurance risk. Currently, 28 insurance pools operate worldwide. National pools are members of the international pool system. The pools cover both third party liability and material damage. Entities insured by pools include not only nuclear power plants but also fuel fabrication plants, research reactors, nuclear waste treatment plants, spent fuel reprocessing plants, facilities for protecting nuclear wastes before disposal, as well as nuclear fuel and facility carriers and suppliers.

    International Nuclear Information System (INIS)

    Nuclear Trafficking Scams are situations where the scam artist(s) offer something (material or information) that is not what he/she/they represent it to be. Example of a scam is when attempt is made to sell fake nuclear material. The offered material may not be nuclear material or may be of a lower grade. The offered material may not actually exist . Radioactive material may be offered as nuclear material. A small sample of actual nuclear material may be offered, but the bulk material may be something else.

  1. Introduction to Nuclear Astrophysics

    International Nuclear Information System (INIS)

    In the first lecture of this volume, we will present the basic fundamental ideas regarding nuclear processes occurring in stars. We start from stellar observations, will then elaborate on some important quantum-mechanical phenomena governing nuclear reactions, continue with how nuclear reactions proceed in a hot stellar plasma and, finally, we will provide an overview of stellar burning stages. At the end, the current knowledge regarding the origin of the elements is briefly summarized. This lecture is directed towards the student of nuclear astrophysics. Our intention is to present seemingly unrelated phenomena of nuclear physics and astrophysics in a coherent framework.

  2. Nuclear reactor theory

    International Nuclear Information System (INIS)

    This textbook is composed of two parts. Part 1 'Elements of Nuclear Reactor Theory' is composed of only elements but the main resource for the lecture of nuclear reactor theory, and should be studied as common knowledge. Much space is therefore devoted to the history of nuclear energy production and to nuclear physics, and the material focuses on the principles of energy production in nuclear reactors. However, considering the heavy workload of students, these subjects are presented concisely, allowing students to read quickly through this textbook. (J.P.N.)

    Herpesviruses assemble and fill their capsids in the infected cell nucleus,and must then move this enormous macromolecular assembly across the nuclear membrane and into the cytoplasm.Doing so is a complex,multi-step process that involves envelopment of the capsid at the inner nuclear membrane and de-envelopment by fusion with the outer nuclear membrane.This process is orchestrated by viral proteins,but requires the modification of cellular structures and mechanisms including the nuclear lamina.In this review I summarize recent research on the mechanism of nuclear envelopment and the viral and cellular systems involved in its execution.

    International Nuclear Information System (INIS)

    An analysis of the development of nuclear energy in Brazil is made since its beginning, showing the fundamental policy changes introduced in the end of the 60's with the purchase of the Angra dos Reis I reactor. This decision discouraged the existing efforts of an autonomous development in nuclear energy. The reaction to this policy led to the Nuclear Deal with Germany, which although incorporating some positive aspects is nor capable to lead to nuclear independence. The presently existing options are discussed, as well as the transformation of the Nuclear Program in a R and D Program based only in the reactors I, II and III, located in Angra dos Reis. (Author)

    Nuclear reactor physics is the core discipline of nuclear engineering. Nuclear reactors now account for a significant portion of the electrical power generated worldwide, and new power reactors with improved fuel cycles are being developed. At the same time, the past few decades have seen an ever-increasing number of industrial, medical, military, and research applications for nuclear reactors. The second edition of this successful comprehensive textbook and reference on basic and advanced nuclear reactor physics has been completely updated, revised and enlarged to include the latest developme

  10. Safety of nuclear ships

    International Nuclear Information System (INIS)

    Interest in the utilization of nuclear steam supply systems for merchant ships and icebreakers has recently increased considerably due to the sharp rise in oil prices and the continuing trend towards larger and faster merchant ships. Canada, for example, is considering construction of an icebreaker in the near future. On the other hand, an accident which could result in serious damage to or the sinking of a nuclear ship is potentially far more dangerous to the general public than a similar accident with a conventional ship. Therefore, it was very important to evaluate in an international forum the safety of nuclear ships in the light of our contemporary safety philosophy, taking into account the results of cumulative operating experience with nuclear ships in operation. The philosophy and safety requirement for land-based nuclear installations were outlined because of many common features for both land-based nuclear installations and nuclear ships. Nevertheless, essential specific safety requirements for nuclear ships must always be considered, and the work on safety problems for nuclear ships sponsored by the NEA was regarded as an important step towards developing an international code of practice by IMCO on the safety of nuclear merchant ships. One session was devoted to the quantitative assessment of nuclear ship safety. The probability technique of an accident risk assessment for nuclear power plants is well known and widely used. Its modification, to make it applicable to nuclear propelled merchant ships, was discussed in some papers. Mathematical models for describing various postulated accidents with nuclear ships were developed and reported by several speakers. Several papers discussed a loss-of-coolant accident (LOCA) with nuclear steam supply systems of nuclear ships and engineering design features to prevent a radioactive effluence after LOCA. Other types of postulated accidents with reactors and systems in static and dynamic conditions were also

  11. Nuclear Energy Data 2013

    International Nuclear Information System (INIS)

    Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants declined in 2012 as a result of operational issues at some facilities and suspended operation at all but two reactors in Japan. Nuclear safety was further strengthened in 2012 following safety reviews prompted by the Fukushima Daiichi nuclear power plant accident. Governments committed to maintaining nuclear power in the energy mix pursued initiatives to increase nuclear generating capacity. In Turkey, plans were finalised for the construction of the first four reactors for commercial electricity production. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'Statlinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link

  12. Polish Nuclear Physics Network

    International Nuclear Information System (INIS)

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

  13. Commercial nuclear power 1990

    International Nuclear Information System (INIS)

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

  14. History of Nuclear India

    Science.gov (United States)

    Chaturvedi, Ram

    2000-04-01

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

  15. The nuclear power decisions

    International Nuclear Information System (INIS)

    Nuclear power has now become highly controversial and there is violent disagreement about how far this technology can and should contribute to the Western energy economy. More so than any other energy resource, nuclear power has the capacity to provide much of our energy needs but the risk is now seen to be very large indeed. This book discusses the major British decisions in the civil nuclear field, and the way they were made, between 1953 and 1978. That is, it spans the period between the decision to construct Calder Hall - claimed as the world's first nuclear power station - and the Windscale Inquiry - claimed as the world's most thorough study of a nuclear project. For the period up to 1974 this involves a study of the internal processes of British central government - what the author terms 'private' politics to distinguish them from the very 'public' or open politics which have characterised the period since 1974. The private issues include the technical selection of nuclear reactors, the economic arguments about nuclear power and the political clashes between institutions and individuals. The public issues concern nuclear safety and the environment and the rights and opportunities for individuals and groups to protest about nuclear development. The book demonstrates that British civil nuclear power decision making has had many shortcomings and concludes that it was hampered by outdated political and administrative attitudes and machinery and that some of the central issues in the nuclear debate were misunderstood by the decision makers themselves.

  16. Overview of nuclear data

    International Nuclear Information System (INIS)

    For many years, nuclear structure and decay data have been compiled and disseminated by an International Network of Nuclear Structure and Decay Data (NSDD) evaluators under the auspices of the International Nuclear Data Committee (INDC) of the International Atomic Energy Agency (IAEA). In this lecture I will discuss the kinds of data that are available and describe various ways to obtain this information. We will learn about some of the publications that are available and Internet sources of nuclear data. You will be introduced to Isotope Explorer software for retrieving and displaying nuclear structure and radioactive decay data. The on-line resources Table of Radioactive Isotopes, PGAA Database Viewer, Nuclear Science Reference Search, Table of Isotopes Educational Website, and other information sources will be discussed. Exercises will be provided to increase your ability to understand, access, and use nuclear data

  17. Nuclear insurance fire risk

    International Nuclear Information System (INIS)

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

  18. Nuclear energy and society

    International Nuclear Information System (INIS)

    Nuclear energy has a strong relation to a society. However, due to accidents and scandals having occurred in recent years, people's reliability to nuclear energy has significantly swayed and is becoming existence of a worry. Analyzing such a situation and grasping the problem contained are serious problems for people engaging in nuclear field. In order that nuclear energy is properly used in society, communication with general public and in nuclear power plant site area are increasingly getting important as well as grasping the situation and surveying measures for overcoming the problems. On the basis of such an analysis, various activities for betterment of public acceptance of nuclear energy by nuclear industry workers, researchers and the government are proposed. (J.P.N.)

    1984-01-01

    This guidebook for clinical nuclear medicine is written as a description of how nuclear medicine procedures should be used by clinicians in evaluating their patients. It is designed to assist medical students and physicians in becoming acquainted with nuclear medicine techniques for detecting and evaluating most common disorders. The material provides an introduction to, not a textbook of, nuclear medicine. Each chapter is devoted to a particular organ system or topic relevant to the risks and benefits involved in nuclear medicine studies. The emphasis is on presenting the rationales for ordering the various clinical imaging procedures performed in most nuclear medicine departments. Where appropriate, alternative imaging modalities including ultrasound, computed tomography imaging, and radiographic special procedures are discussed. Comparative data between nuclear medicine imaging and other modalities are presented to help guide the practicing clinician in the selection of the most appropriate procedure for a given problem.

The items are elaborated in the following chapters: Nuclear power today and for the future, Sweden and its power supply, The history of nuclear power in Sweden, Nuclear Sweden today, Operating experience in 10 nuclear power units, Maintenance experience, Third-generation BWR-plants commissioned in five years, Personnel and training, Reactor safety, Quality assurance and quality control, Characteristic features of the ASEA-ATOM BWR, Experience of PWR steam generators, Nuclear fuel supply and management, Policy and techniques of radioactive waste management, Nuclear energy authorities and Inherently safe LWR. The publication is concluded by facts in brief and a statement by the Director General of IAEA. (G.B.)

  1. The nuclear winter

    International Nuclear Information System (INIS)

    Nuclear winter is an example of possible secondary effects, and if we speak of secondary we are thinking of small-scale second-order effects, but a nuclear winter is not a second-order effect. If you calculate the amount of heat produced by a nuclear explosion, it is a very small amount which does not have any chance of changing the Earth's climate, but a nuclear explosion drives or stars some new mechanism - the mechanism of nuclear winter - after 100 megatons of dust are transferred to the upper atmosphere. Another example of such amplification is radioactive fall-out, especially long-life radioactive fall-out after the possible elimination of the nuclear power industry, nuclear storage and distribution of storage waste around the globe. This is a very powerful amplification mechanism

  2. Lessons from nuclear disasters

    International Nuclear Information System (INIS)

    The most severe and worst of all nuclear disasters is, needless to say, the explosion of an atomic bomb. The WHO committee on the effects of nuclear war, established in 1982, concluded that the only approach to the treatment of the health effects of nuclear warfare is primary prevention, that is, the prevention of nuclear war. Nuclear disasters have also occurred in nuclear power plants and nuclear facilities, causing various damage and acute anxiety among the workers and general public, but thus far the related health effects have not always been correctly evaluated. Such problems as exposed population, individual exposed dose and health risks which are associated with these evaluation efforts are discussed here. (author)

  3. Nuclear fuel transporting container

    International Nuclear Information System (INIS)

    Purpose: To prevent the failure of nuclear fuel rods constituting a nuclear fuel assembly contained to the inside of a container upon fire accidents or the likes. Constitution: The nuclear fuel transportation container comprises a tightly sealed inner vessel made of steels for containing a nuclear fuel assembly consisting of bundled nuclear fuel rods, a heat shielding material surrounding the inner vessel, shock absorber and an outer vessel. A relief safety valve is disposed to the inner vessel that actuates at a specific pressure higher than the normal inner pressure for the nuclear fuel rods of the fuel assembly and lower than the allowable inner pressure of the inner vessel. The inside of the inner vessel is pressurized by way of the safety valve such that the normal inner pressure in the inner vessel is substantially equal to the normal inner pressure for the nuclear fuel rods.

  4. Dynamic nuclear spin polarization

    International Nuclear Information System (INIS)

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

  5. The nuclear power cycle

    International Nuclear Information System (INIS)

    Fifty years after the first nuclear reactor come on-line, nuclear power is fourth among the world's primary energy sources, after oil, coal and gas. In 2002, there were 441 reactors in operation worldwide. The United States led the world with 104 reactors and an installed capacity of 100,000 MWe, or more than one fourth of global capacity. Electricity from nuclear energy represents 78% of the production in France, 57% in Belgium, 46% in Sweden, 40% in Switzerland, 39% in South Korea, 34% in Japan, 30% in Germany, 30% in Finland, 26% in Spain, 22% in Great Britain, 20% in the United States and 16% in Russia. Worldwide, 32 reactors are under construction, including 21 in Asia. This information document presents the Areva activities in the nuclear power cycle: the nuclear fuel, the nuclear reactors, the spent fuel reprocessing and recycling and nuclear cleanup and dismantling.

    2013-01-01

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

  7. Thermodynamics of nuclear transport

    Science.gov (United States)

    Wang, Ching-Hao; Mehta, Pankaj; Elbaum, Michael

    Molecular transport across the nuclear envelope is important for eukaryotes for gene expression and signaling. Experimental studies have revealed that nuclear transport is inherently a nonequilibrium process and actively consumes energy. In this work we present a thermodynamics theory of nuclear transport for a major class of nuclear transporters that are mediated by the small GTPase Ran. We identify the molecular elements responsible for powering nuclear transport, which we term the ``Ran battery'' and find that the efficiency of transport, measured by the cargo nuclear localization ratio, is limited by competition between cargo molecules and RanGTP to bind transport receptors, as well as the amount of NTF2 (i.e. RanGDP carrier) available to circulate the energy flow. This picture complements our current understanding of nuclear transport by providing a comprehensive thermodynamics framework to decipher the underlying biochemical machinery. Pm and CHW were supported by a Simons Investigator in the Mathematical Modeling in Living Systems grant (to PM).

  9. The nuclear challenge

    International Nuclear Information System (INIS)

    Information is given about the world-wide energy resources, with a particular accent on the part delivered by nuclear power plants. General trends of energetic needs and consumption and the participation of actually used energy sources are outlined. All the aspects of nuclear power production are considered: the fission and fusion process, the fuel cycle and a short description is given of the different reactor types. The pollution and contamination due to different energy sources, the effects of nuclear radiation on man and environment and the risk of accidents due to different human activities or natural events is reviewed. The Three Mile Island accident is analysed. The author analyses the economical aspects of the development of nuclear power plants, the cost of the electricity production and the Belgian and French nuclear programmes. A short reference to the non-proliferation treaty and possible diversion of nuclear materials is given. Finally the social implications of nuclear energy developments are reviewed. (MDC)

  10. Clinical nuclear medicine

    International Nuclear Information System (INIS)

    The importance of nuclear methods within today's medicine derives decisively from the field of diagnostics. Among the clinical treatment possibilities on the whole, therapy with unsealed radioactive sources is for the time being restricted to few diseases. The use of radioactive labeling in biology, biochemistry and, especially, pharmacology and the rest of fundamental medical research does not belong to the actual specialty of nuclear medicine. Nuclear in-vitro diagnostics, which currently account for about two thirds of all activities in nuclear medicine, are largely excluded from this survey, which is mainly restricted to nuclear diagnostics in vivo. This presentation of nuclear diagnostics in vivo is addressed above all to non-specialists who are to be made familiar with the modern methods of clinical nuclear medicine so that these investigation methods could be more effectively used in future both with qualitative and quantitative regards.

    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.

  14. Nuclear energy: considerations about nuclear trade

    International Nuclear Information System (INIS)

    A general view of historical aspects of nuclear energy and the arrangements to assure its use for peaceful purposes are presented. Then the internal character of nuclear energy in a juride context is demonstrated; some consideration about the international organizations and conventions and the Brazilian Legislation in the nuclear area are examined. It also deals with the political aspects of nuclear trade and the function of IAEA in this are. Furthermore the restrictions imposed by Non-Proliferation Treaty-NPT, the objectures of the Tlatelolco Treaty and ''London Club'' guidelines. Afterwards the bilateral cooperation under taken by countries and its agreements are discussed. Besides some aspects of agreements made between United States, France Germany and Brazil are discussed

  15. China's nuclear safety regulatory body: The national nuclear safety administration

    International Nuclear Information System (INIS)

    The establishment of an independent nuclear safety regulatory body is necessary for ensuring the safety of nuclear installations and nuclear fuel. Therefore the National Nuclear Safety Administration was established by the state. The aim, purpose, organization structure and main tasks of the Administration are presented. At the same time the practical examples, such as nuclear safety regulation on the Qinshan Nuclear Power Plant, safety review and inspections for the Daya Bay Nuclear Power Plant during the construction, and nuclear material accounting and management system in the nuclear fuel fabrication plant in China, are given in order to demonstrate the important roles having been played on nuclear safety by the Administration after its founding

    Internal membrane bound structures sequester all genetic material in eukaryotic cells. The most prominent of these structures is the nucleus, which is bounded by a double membrane termed the nuclear envelope (NE). Though this NE separates the nucleoplasm and genetic material within the nucleus from the surrounding cytoplasm, it is studded throughout with portals called nuclear pore complexes (NPCs). The NPC is a highly selective, bidirectional transporter for a tremendous range of protein and...

    In April 2009, 61 states and seven international organisations with a total of 808 participants and observers convened in Beijing at an international ministerial conference, organised by the International Atomic Energy Agency (IAEA) in co-sponsorship with the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA), to deal with nuclear energy in the 21st century.1 In his concluding statement, the president of that conference stressed that “the conference...

  18. Nuclear power supply (Japan Nuclear Safety Institute)

    International Nuclear Information System (INIS)

    After experienced nuclear disaster occurred on March 11, 2011, role of nuclear power in future energy share in Japan became uncertain because most public seemed to prefer nuclear power phase out to energy security or costs. Whether nuclear power plants were safe shutdown or operational, technologies were requisite for maintaining their equipment by refurbishment, partly replacement or pressure proof function recovery works, all of which were basically performed by welding. Nuclear power plants consisted of tanks, piping and pumps, and considered as giant welded structures welding was mostly used. Reactor pressure vessel subject to high temperature and high pressure was around 200mm thick and made of low-alloy steels (A533B), stainless steels (308, 316) and nickel base alloys (Alloy 600, 690). Kinds of welding at site were mostly shielded-metal arc welding and TIG welding, and sometimes laser welding. Radiation effects on welding of materials were limited although radiation protection was needed for welding works under radiation environment. New welding technologies had been applied after their technical validation by experiments applicable to required regulation standards. Latest developed welding technologies were seal welding to prevent SCC propagation and temper-bead welding for cladding after removal of cracks. Detailed procedures of repair welding of Alloy 600 at the reactor outlet pipe at Oi Nuclear Power Plants unit 3 due to PWSCC were described as an example of crack removal and water jet peening, and then overlay by temper-bead welding using Alloy 600 and clad welding using Alloy 690.

    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.

  20. The Nuclear Symmetry Energy

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