Full textAbstract:
El objetivo general de esta investigación es analizar el sistema de comunicación de las centrales nucleares de España y, partiendo de esa premisa, realizar una propuesta comunicativa-fundamentada en la estrategia-que contribuya a la reparación de la legitimidad social de la energía nuclear.
La metodología empleada para esta investigación tiene cuatro partes: fuentes bibliográficas, revisión de textos científicos sobre empresa, RSC y comunicación; comunicación y legislación nuclear; informes de producción y consumo de electricidad, y estudios de opinión pública y energía nuclear; fuentes personales, entrevistas en profundidad a los responsables de la comunicación en las centrales nucleares de España; análisis de calidad de las páginas web de las plantas atómicas; y un análisis de contenido de diarios de proximidad a las centrales nucleares.
La razón para realizar esta investigación, es que la producción de electricidad de origen nuclear tiene ventajas e inconvenientes: es un tipo de energía que da estabilidad a la red y garantiza el suministro; no emite gases contaminantes a la atmósfera; es una actividad muy regulada; tiene un impacto socioeconómico relevante en las zonas donde se asientan las instalaciones nucleares; genera residuos radioactivos y en caso de accidente los riesgos para la salud de las personas y el medio ambiente son potenciales. Sin embargo, es una energía cuestionada.
La opinión pública en España se posiciona en contra de la energía nuclear y de las plantas atómicas, pero las encuestas dicen que cuando los entrevistados conocen más información sobre la industria atómica aumenta la aceptación hacia esta fuente de energía. Este vacío informativo entre las centrales y sus públicos justifica que la función comunicativa tenga un papel protagonista.
Otro asunto que justifica que la comunicación es necesaria para este sector es que su viabilidad no depende exclusivamente de producir un bien, como es la electricidad, ni de hacerlo de una manera sostenible, eficiente, segura o rentable. En el sector nuclear existen unos grupos de interés con capacidad de decidir sobre el futuro de las instalaciones como, por ejemplo, los gobiernos, la empresa propietaria o el organismo regulador; y otros grupos de interés que tienen prestigio en el debate e influencia en la opinión pública, como son los medios de comunicación o los grupos ecologistas y antinucleares, entre otros.
Nuestra propuesta de investigación se cimienta en cuatro ejes: una orientación empresarial para reparar la legitimidad social; unos principios que inspiren la Comunicación Nuclear; una estructura de Dirección de Comunicación; y un plan estratégico de comunicación (interna, externa, y de crisis).
Entendemos que para reparar la legitimidad de la energía nuclear en primer lugar las prácticas empresariales tienen que ser responsables para, en segundo lugar, transmitirlas a los diferentes públicos.
Y consideramos que la comunicación nuclear debe sostenerse en un diálogo auténtico y constante con los grupos de interés. Porque creemos que la comunicación en una central nuclear debe responder a las siguientes características: estratégica, organizada, directiva, proactiva, responsable, de servicio y relacional.
Desde un punto académico esta investigación cubre un vacío ya que no hay un desarrollo teórico sobre la Comunicación Nuclear. Y desde un punto de vista práctico, los resultados de esta investigación pueden ser aplicados a la gestión comunicativa de cualquier planta atómica. Por lo tanto creemos que la esta investigación es conveniente tanto para el conocimiento de la sociedad, el mundo académico como el propio sector.The general objective of this research is to analyze the communication system of nuclear power plants in Spain and, based on that premise, to make a communicative proposal based on the strategy that contributes to the repair of the social legitimacy of nuclear energy. The methodology used for this research has four fundamental points: bibliographic sources, review of scientific texts about business, CSR and communication, communication and nuclear Legislation; reports on electricity production and consumption, and studies of public opinion and nuclear energy; personal sources, in-depth interviews with those responsible for communication in Spain's nuclear power plants; quality analysis of the web pages of atomic plants; and an analysis of content of newspapers with proximity to nuclear power plants. The production of electricity of nuclear origin has advantages and disadvantages: it is a type of energy that gives stability to the network and guarantees the supply; it does not emit polluting gases into the atmosphere; it is a highly regulated activity; it has a relevant socioeconomic impact in the areas where the nuclear facilities are located; it generates radioactive waste and in case of accident the damage to the health of people and the environment is possible. Public opinion in Spain is positioned against nuclear energy and atomic plants, but surveys say that when the interviewees know more information about the atomic industry, the acceptance towards this source of energy increases. This information gap between the nuclear power plants and their public justifies that the communicative function has a leading role. Another issue that justifies that communication is necessary for this sector is that its viability does not depend exclusively on producing a good, such as electricity, nor on doing so in a sustainable, efficient, safe or profitable way. In the nuclear sector there are interest groups with the capacity to decide on the future of the facilities, such as, the governments, the owner company or the regulatory body; and other interest groups that have prestige in the debate and influence on public opinion, such as the media or environmental and anti-nuclear groups, among others. Our proposal is based on four axes: a business orientation to repair social legitimacy; principles that inspire Nuclear Communication; a Communication Management structure; and a strategic communication plan (internal, external, and crisis). We understand that in order to repair the legitimacy of nuclear energy, first of all business practices must be responsible for, secondly, transmitting them to different publics. Moreover we believe that nuclear communication must be sustained in a genuine and constant dialogue with interest groups, because we believe that communication in a nuclear power plant must respond to the following characteristics: strategic, organized, directive, proactive, responsible, service and relational. From an academic viewpoint, this research covers a vacuum since there is no theoretical development on Nuclear Communication. And from a practical point of view, the results of this research can be applied to the communicative management of any atomic plant. Therefore, we believe that this research is suitable for the knowledge of society, the academic world and the sector itself.

Rajashekaran, Dhruv. "Is Pursuing Nuclear Energy in India's Strategic Interest?" Thesis, Webster University, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=1526151.
Full textAbstract:
As a developing country with the second largest population in the world, India's energy needs will continue to grow steadily in the coming decades. A significant proportion of India's oil, coal and natural gas are imported because of a dearth of indigenous energy resources. This creates a situation of energy dependence and is a potential national security issue. As a result, the government is embarking on an ambitious plan to have nuclear power generate 25% of electricity in 2050 – up from 3.7% in 2012. The aim is to be running on thorium fast-breeder reactors, that are currently in development, by that time. India's vast reserves of thorium would mean that this would improve energy security, while also improving access to energy for the large part of its population that remains without it.
However, nuclear energy is controversial. Issues of safety and viability must be addressed adequately if nuclear energy is to be pursued. Civil-society concerns about the displacement of people and the degradation or changes in environment around plants and its consequences must also be appropriately addressed. The aim of this paper is to ascertain if it is indeed in India's strategic interest to invest in nuclear energy. Within a theoretical framework of energy security the paper will seek to identify what changes should be made in the sector to guide and manage the process of expanding nuclear-power generation is also important if prescribing this course of action.

Full textAbstract:
Nuclear weapons were rapidly incorporated into the policies for maintaining the national security objectives of both the Soviet Union and the United States--in spite of poorly understood nuclear weapons effects. The nuclear winter hypothesis, the basis of which was first proposed in 1982, directed scientific research into the consequences of massive amounts of dust and smoke, from nuclear detonations, on the earth's climate and subsequently on the ecology of the earth. This thesis presents the evolution of the nuclear winter hypothesis in order to elucidate its unique aspects for global devastation and the consensus of plausibility which the hypothesis holds in the scientific community. The hypothesis has aroused a flurry of debate on its implications for nuclear policy. With the historical aspects of the nuclear era as a backdrop, the question of incorporating new scientific information on the consequences of nuclear war into policy is discussed. The observed responses of the U.S. and Soviet Union and the implications for future actions in response to the nuclear winter hypothesis are examined-- leading to the conclusion that the hypothesis will have little or no impact on U.S. and Soviet nuclear policy.

Full textAbstract:
The concept of Strategic Culture was developed during the Cold War years as a tool to analyse the nuclear policies of the Soviet Union and the United States, in an effort to assess the likelihood of their utilising their nuclear capabilities. Strategic Culture provides a useful lens through which we may understand the context, outlook and behaviour of states, shedding light on the way they perceive the international community and their role within it. As the Cold War came to an end, the focus of Strategic Culture literature shifted from the nuclear bipolarity that characterised U.S.-Soviet relations, to focus on other states and issue areas that dominated the international agenda within the New World Order. This thesis seeks to return to the original tenets of Strategic Culture, bringing attention back to the initial remits of this area of study, that is, the nuclear strategic cultures of the U.S.A. and Russia. Further to identifying the strategic cultures of the United States and Russia, this research questions whether these have been impacted by the change in international order brought on by the end of the Cold War. This work will also question whether nuclear weapons contorted their respective strategic cultures, or whether their strategic cultures were insulated from the impact of nuclear weapons. It will also assess whether the differences in strategic cultures have brought about differences in nuclear policy.

Grabrovaz, Meaghan. "An investigation into the forecasting of skills in nuclear decommissioning." Thesis, University of Central Lancashire, 2017. http://clok.uclan.ac.uk/23759/.
Full textAbstract:
This study explores the nature of skills forecasting in nuclear decommissioning and that which makes skills forecasting information useful. The study adopts a pragmatic approach using an interpretative, qualitative case study research design and draws on aspects of a critical realist approach to uncover, deconstruct and challenge some ‘norms’ in skills forecasting. The study makes an original contribution to knowledge through the identification of nineteen factors that influence skills forecasting in the nuclear industry. It also generates a baseline of knowledge on the theory and practice of skills forecasting and management through a review of the literature on skills, forecasting, skills forecasting and workforce planning and relevant aspects of public sector management and HRM. The study documents and compares current skills forecasting practice amongst UK site licensed companies and selected supply chain companies. Such research has not previously been conducted in the nuclear decommissioning industry. This answers research questions about why, and how, different groups in the sector perform skills forecasting and how variations in approaches affect the information produced. It also answers research questions about who uses skills forecasting information, and how. Together with a review of current problems with skills information, this contributes to an understanding of what makes skills information useful. The research evidences that while the industry has some common features with other High Reliability Organisations, there are unique dimensions which make this research significant. Some ‘norms’ operating in skills forecasting were challenged including how it is being used, eg as an agent for change by some groups, and assumptions about the potential availability of skills from the supply chain. The literature review was used to construct a practical-ideal type, an approach derived from classical pragmatism offering a version of a nearly ideal process, on the understanding that this is socially constructed and subject to continual change. Existing practice is evaluated against this practical-ideal type in a unique application of this methodology in the nuclear decommissioning context.

ELETROBRAS - CENTRAIS ELÉTRICAS BRASILEIRAS S. A.Nos últimos oito anos, o setor elétrico brasileiro tem sofrido profundas transformações em sua estrutura básica. Porém, ainda há muito a fazer, principalmente na área de diversificação de energia, uma vez que a matriz energética do setor elétrico está concentrada em uma só fonte - a hidráulica. Esta pesquisa tem como objetivo apresentar um arcabouço analítico com os recursos e as competências necessários/desejáveis à exploração da energia nucleoelétrica no país. A investigação foi desenvolvida, usando a metodologia de estudo de caso, escolhendo como objeto de pesquisa a Eletrobrás Termonuclear - Eletronuclear. Coletados por meio de investigação documental/telematizada, formulário predominantemente estruturado e entrevistas, os dados da pesquisa foram tratados com métodos quantitativos e qualitativos. A interpretação e a análise dos dados foram realizadas com base no referencial teórico, fundamentado em revisão de literatura pertinente à área de estudo, com auxílio do modelo genérico integrativo de Macedo-Soares (2000 e 2002), em suas versões tradicional e relacional. Em seguida, utilizando o método AHP (Analytic Hierarchy Process), realizou-se uma hierarquização das categorias de recursos e de competências apuradas, em ordem de importância, segundo a percepção dos gestores participantes da pesquisa. Os resultados evidenciaram inconsistências entre os objetivos estratégicos explicitados pela empresa, sua capacidade financeira, os fatores macroambientais políticos e os atores estratégicos. Dentre as recomendações resultantes da pesquisa, o arcabouço de recursos e competências proposto destaca as categorias mais relevantes e alerta para aquelas que requerem ações mais efetivas com vistas a viabilizar a geração de energia nucleoelétrica no Brasil.
Since 1996, the basic structure of the Brazilian electric sector has been changing dramatically. However, these changes have not brought great improvement in terms of electric energy diversification, considering that the sector`s energetic matrix is basically concentrated in a single source - the hydraulic. The objective of this study is to develop an analytic framework with the necessary/desirable resources and competencies to explore the nuclear-electric energy in Brazil. The investigation was carried out through the case study methodology and had Electronuclear - Brazil`s state-owned nuclear energy producer - as object of study. Data collected through documental/telematic investigations and mainly structured interviews, were handled with qualitative and quantitative methods. The data interpretation and analysis were conducted based on the theoretical references from the literature review, with the support of the systemic and integrative model - traditional and relational versions - developed by Macedo-Soares(2000 e 2002). After that, utilizing the Analytic Hierarchy Process, the resources and competencies were organized in different groups and classified by priority, according to managerial perceptions. The results highlight inconsistencies between the firm`s strategy objectives, its financial resources, the political macro- environmental factors and the strategic actors. Among the recommendations made as a result of the research, the framework of resources and competencies shows the more relevant groups and emphasizes some aspects that need effective actions in order to explore the nuclear-electric energy in Brazil.

McGeorge-Henderson, Ben P. "Novel acquisition strategies for dissolution dynamic nuclear polarisation." Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/43266/.
Full textAbstract:
Dynamic Nuclear Polarisation (DNP) produced molecules with spin polarisation levels that are up to three orders of magnitude larger than their thermal equilibrium values. Most DNP mechanisms work at temperatures of 2 K and lower, meaning that the sample is stored in the solid-state. Combining DNP with a rapid temper- ature jump to room temperature allows liquid-state NMR analysis with a signal that is ve orders of magnitude higher than observed with thermal polarisation. However, the information obtained during a dissolution experiment is limited by the intrinsic liquid-state longitudinal relaxation of the spins of interest. is thesis looks to increase the information acquired in a number of ways. First, by devel- oping a new dissolution system for the dual iso-centre magnet it was possible to reproducibly perform enhanced NMR acquisition 600 ms following sample disso- lution. is has allowed the observation of hyperpolarised 13C spins with T1 times as low as 200 ms. Complimentary information can be obtained following sample dissolution by observing multiple spin species simultaneously. 13C and 15N spins are both polarised by microwave irradiation of the same frequency, so both can be analysed during a single dissolution DNP experiment. A novel probe has been used that contains six individual 13C microcoils. ese coils are separated in space and operate independently. is probe, in conjunction with dissolution DNP, can be used for observing dynamic molecular information on the time scale of 200 ms, however with further development this time scale should drop to less than 100 ms while maintaining a required minimum spectral resolution. Initial tests have been performed with both thermally polarised and hyperpolarised samples.

Full textAbstract:
The Intermediate-Range Nuclear Force (INF) controversy was one of the most intense intra-Alliance debates experienced by NATO. The depth of the dispute, especially between the US and the European NATO members, threatened the very unity and cohesion of the Alliance itself. The INF controversy was the result of two factors: first, the establishment of strategic parity by the Soviet Union which brought into question the credibility of the US security guarantee to Europe; and second, the widening gap in the political and strategic interests of the US and its European allies.
These factors combined to produce the two central--and conflicting--forces at work during the INF debate. The Europeans sought strategic reassurance, in the form of theatre-nuclear systems, to restore the integrity of the seamless web of deterrence. The divergence of political and strategic interests between the US and Europe, however, meant conflict over the posture and character of any new force. In the interests of preserving the unity of the Alliance, these problems were "solved" in typical Alliance fashion; through compromising to a consensus.
The December 12 decision was based on erroneous and outdated conceptions of the significance of nuclear weapons for deterrence in Europe. What NATO planners, and many western analysts, have failed to recognize is the diminishing effectiveness of US nuclear weapons in maintaining effective deterrence in Western Europe. Deterrence in Europe is not primarily dependent on US nuclear forces and the threat of deliberate nuclear escalation they imply. Rather, deterrence in Europe should be understood as a compound product of many risk factors. Henceforth, thinking about NATO's deterrent requirements must recognize the limited utility of successive deployments of US nuclear forces as a deterrent. Greater reliance must be placed on the deterrent value of other risk factors which exist in the European theatre, most notably the increasingly powerful and discriminating capabilities of the French and British nuclear forces.Arts, Faculty of

Full textAbstract:
This thesis is a study of an attempt to help create a transnational movement against the nuclear arms race and the Cold War in the 1980s. The attempt began with the drafting and launch of the Appeal for European Nuclear Disarmament in early 1980. The thesis describes and analyses the work of the British group, European Nuclear Disarmament, or END, which was founded in order to further the aims outlined in the Appeal. The thesis examines END's work in three, overlapping, geographical areas: Britain, where END acted mainly as a pressure group on and/or ginger group within CND in an attempt to internationalize - END-ize - its work; in Western Europe (including Britain), where END (with other Western peace groups) was trying to create and sustain enduring ties amongst Western peace groups; and across the East-West divide, where END was one of a number of groups that engaged in dialogue with independent forces in the Soviet bloc - while maintaining relations with the regimes - with the aim of creating some kind of pan-European alliance that would bring together above all these forces and Western peace groups. The study is conducted in terms of an explanatory framework that emphasizes the pre-existing networks out of which END emerged; the distinctive END worldview or 'frame' and the ways in which END supporters campaigned in its terms, tried to persuade others to adopt it, and/or adapted it - above all in dialogue with independent groups in the Soviet bloc; the resources and structure that helped determine the work END activists could do; the way in which this campaigning was shaped by END's relationship with other peace groups, in Britain above all CND; and the political opportunities and constraints that END activists faced. To date there has been no full-length study of END nor one that analyses the various dimensions of its campaign and how they shaped each other. This thesis thus aims to be a contribution to our knowledge of the West European peace movements of the 1980s; it also hopes to add to our understanding of transnational social-movement campaigning.

Full textAbstract:
The thesis deals with the communication of the Temelín Nuclear Power Plant. Nuclear sources of energy are currently a sensitive issue. The planned extension of the Temelín NPP is also a frequently discussed topic in the Czech Republic; it affects many stakeholders and faces increased public and media interest. The goal of the thesis is to create a communication strategy of the Temelín NPP targeted to the public. The draft of the strategy is based on the conclusions of the SWOT analysis focused on the Temelín NPP communication, furthermore, on the analysis of selected online communication tools used by the Temelín NPP, and mainly on the quantitative survey conducted with the purpose to find out the actual public perception of the Temelín NPP and the public attitude to nuclear energy in general. The strategy also uses the knowledge of the company ČEZ media analysis and the findings of the sociological survey among inhabitants of the area close to Temelín compiled by STEM/MARK research agency.

North Korea's relationship with nuclear technology has concerned the world for decades. A wide array of negotiation methods from punitive sanctions to energy assistance have been attempted to dissuade the nation from developing its weapons program -- but every resolution has been temporary at best. We focus on the United States' negotiation strategy and attempt to uncover inconsistencies between it and the material facts of the North Korean situation. The historical record of past negotiations and rhetoric used by each party during previous attempts are considered in our analysis, in order to construct a picture of diplomatic evolution over time. We believe that the North Korean bargaining position -- which has been highly consistent across decades of cyclic negotiating behavior -- is fundamentally incompatible with US demands for complete denuclearization.

Search the library catalog for the location and call number.Current realist explanations of why states decide to develop nuclear weapons cannot account for the behavior of states that lack a clear strategic threat. An alternative explanation is necessary to explain such behavior. I argue that domestic regimes in states with no clear strategic threat may develop nuclear weapons in order to ensure their survival. Such regimes are internationally isolated, under pressure from major powers in the international system and possess some preexisting nuclear capacity. Under these conditions, increasing domestic instability causes regimes to pursue a course of nuclear development. Nuclear weapons allow a regime to change the preferences of the great powers that would otherwise prefer to see the regime overthrown. If the regime possesses nuclear weapons, because of the costs and risks associated with those weapons, the great power will favor maintenance of the status quo and may even prop up a regime it intensely dislikes.

This work is focused on the strategy for utilizing high-burnup fuel in pressurized water reactors (PWR) with special emphasis on the full array of neutronic considerations. The historical increase in batch-averaged discharge fuel burnup, from ~30 MWd/kg in the 1970s to ~50 MWd/kg today, was achieved mainly by increasing the reload fuel enrichment to allow longer fuel cycles: from an average of 12 months to about 18 months. This also reduced operating costs by improving the plant capacity factor. Recently, because of limited spent fuel storage capacity, increased core power output and the search for increased proliferation resistance, achieving burnup in the 70 to 100 MWd/kg range has attracted considerable attention. However the implications of this initiative have not been fully explored; hence this work defines the practical issues for high-burnup PWR fuels based on neutronic, thermal hydraulic and economic considerations as well as spent fuel characteristics. In order to evaluate the various high burnup fuel design options, an improved MCNP-ORIGEN depletion program called MCODE was developed. A standard burnup predictor-corrector algorithm is implemented, which distinguishes MCODE from other MCNP-ORIGEN linkage codes. Using MCODE, the effect of lattice design (moderation effect) on core design and spent fuel characteristics is explored. Characterized by the hydrogen-to-heavy-metal ratio (H/HM), the neutron spectrum effect in UO2/H2O lattices is investigated for a wide range of moderation, from fast spectra to over-thermalized spectra. It is shown that either wetter or very dry lattices are preferable in terms of achievable burnup potential to those having an epithermal spectrum. Wet lattices are the preferred high burnup approach due to improved proliferation resistance. The constraint of negative moderator temperature coefficient (MTC) requires that H/HM values (now at 3.4) remain below ~6.0 for PWR lattices. Alternative fuel choices, including the conventional solid pellets, central-voided annular pellets, Internally- & eXternally-cooled Annular Fuel (IXAF), and different fuel forms are analyzed to achieve a wetter lattice. Although a wetter lattice has higher burnup potential than the reference PWR lattice, the requirement of a fixed target cycle energy production necessitates higher initial fuel enrichments to compensate for the loss of fuel mass in a wetter lattice. Practical issues and constraints for the high burnup fuel include neutronic reactivity control, heat transfer margin, and fission gas release. Overall the IXAF design appears to be the most promising approach to realization of high burnup fuel. High-burnup spent fuel characteristics are compared to the reference spent fuel of 33 MWd/kg, representative of most of the spent fuel inventory. Although an increase of decay power and radioactivity per unit mass of initial heavy metal is immediately observed, the heat load (integration of decay power over time) per unit electricity generation decreases as the fuel discharge burnup increases. The magnitude of changes depends on the time after discharge. For the same electricity production, not only the mass and volume of the spent fuel are reduced, but also, to a lesser extent, the total heat load of the spent fuel. Since the heat load in the first several hundred years roughly determines the capital cost of the repository, a high burnup strategy coupled with adequate cooling time, may provide a cost-reduction approach to the repository. High burnup is beneficial to enhancing the proliferation resistance. The plutonium vector in the high-burnup spent fuel is degraded, hence less attractive for weapons. For example, the ratio of Pu-238 to Pu-239 increases with burnup to the 2.5 power. However, the economic benefits are uncertain. Under the current economic conditions, the PWR fuel burnup appears to have a shallow optimum discharge burnup between 50 and 80 MWd/kg. The actual minimum is influenced by the financing costs as well as the cost of refueling shutdowns. Since the fuel cycle back-end benefits will accrue to the federal government, the current economic framework, such as the waste fee based on the electricity produced rather than volume or actinide content, does not create an incentive for utilities to increase burnup. Different schemes exist for fuel management of high burnup PWR cores. For the conventional core design, a generalized enrichment-burnup correlation (applicable between 3 w/o and 20 w/o) was produced based on CASMO/SIMULATE PWR core calculations. Among retrofit cores, increasing the number of fuel batches is preferred over increasing the cycle length due to nuclear fuel cycle economic imperatives. For future core designs, a higher power-density core is a very attractive option to cut down the busbar cost. The IXAF concept possesses key design characteristics that provide the necessary thermal margins at high core power densities. In this regard, the IXAF fuel deserves further investigation to fully exploit its high burnup capability.

Full textAbstract:
By identifying three key variables – international aid, international acceptance, and credible threat – that are significant in North Korean negotiations, this paper identifies several policy alternatives that present viable American concessions for a more secure Korean nuclear environment. Manipulation of these policy levers by the United States is intended to compel North Korea into concessions that will ultimately lessen the country’s humanitarian burden, improve bilateral relations, and create a more stable region by curtailing nuclear proliferation. For the United States to effectively extract concessions from North Korea, it must create incentives for compliance by changing the North Korea’s calculation of the three bargaining variables away from the equilibrium position. This paper finds that maintenance of the status quo is the most strategically secure policy for the United States if denuclearization by North Korea is improbable. Alteration of the status quo will result in a stronger North Korea (or at the very least, a strategically weaker United States), something that is both domestically unpalatable and not in their direct interest. Unless the United States can accept North Korea as a nuclear state and grant it the corresponding concessions needed to stabilize the region, it is unlikely that a new nuclearized direction will occur. Continuation of the current American foreign policy reflects the incompatibility of the two countries’ preferences and demands; it is a rationalist explanation for what seems an arbitrary strategy. In examining the United States’ current relationship with North Korea as a rational response to the regime’s noncompliance rather than a policy failure, this paper draws on bargaining theory and strategies of nuclear deterrence to consider the strategies available to engage other emerging nuclear powers.

Full textAbstract:
This thesis explores the ideological bases of the global governance of nuclear weapons by analysing the role of civil society, an actor generally left aside by nuclear scholarship. Here the question of nuclear order is tackled with an unconventional approach that combines critical works in nuclear studies, critical constructivist works on security, and Antonio Gramsci’s theory of civil society. Such approach brings civil society to the forefront of analytical attention in order to show the cultural domination exercised by the bomb by inquiring into the common sense nature of nuclear discourse. This rests on the assumption that uncritically accepted ideas about what nuclear weapons do have been instrumental in generating the current nuclear order that, although under mounting challenges, remains based on a hierarchy between states protected by the bomb and all the rest. To understand how civil society challenges and reproduces that order, this thesis analyses the calls for nuclear disarmament advanced by organised collective actors and inquires, in a Gramscian way, into the common sense ingrained in those calls as well as their ability to constitute a united front. As a result, the thesis problematises the notion of disarmament, marking the importance of a struggle on its very concept between reductionist and abolitionist frames. It indicates that while the latter are involved in a radical opposition, the former are culturally dominated by the system of deterrence, thus coming to represent two distinct historic blocs: a counter-hegemonic opposition, on one hand, and an unwitting part of the hegemonic apparatus, on the other. This thesis concludes that 1) civil society is far from having created a unity of intent; and 2) the bases for the reliance on nuclear weapons are deeply entrenched, because of the pervasiveness, even inside civil society, of a common sense view of the nuclear threat.

O presente trabalho desenvolve o tema da dissuasão nuclear, partindo de uma discussão teórica sobre alguns conceitos desenvolvidos pela escola neorrealista de Relações Internacionais. Especificamente entra em consideração a obra de Kenneth Waltz e de John Mearsheimer, com vistas à elucidação de termos como poder, polaridade e capacidade nuclear. Num segundo momento, para fazer um contraponto à escola neorrealista, são abordados autores dos Estudos Estratégicos, com destaque para Bernard Brodie, Thomas Schelling, Lawrence Freedman, Colin Gray e Eugenio Diniz. Procura-se retratar, entre outros fatores, a evolução do pensamento estratégico nuclear ao longo da Guerra Fria. O trabalho também é permeado por questões relacionadas com uma elaborada explanação do que vem a ser dissuasão nuclear, aqui entendida como capacidade de poder. Embora grande parte do esforço desse trabalho esteja voltada para questões de cunho teórico, o refinamento da literatura permite, inerentemente, que o debate se estenda para o campo prático/político. Verificar quais são os pré-requisitos para um país ser considerado uma potência nuclear, bem como o significado e as implicações práticas disso tudo, permeiam grande parte da presente pesquisa. Acima de tudo, cabe verificar quem a Índia é capaz de dissuadir com as suas forças estratégicas/nucleares. Após a apresentação de um breve panorama securitário do subcontinente indiano, para que se tenha uma maior e melhor compreensão do que levou a Índia a se nuclearizar, o capítulo final desenvolve o tópico das implicações da dissuasão nuclear como capacidade de poder, aplicado ao caso indiano.This dissertation deals with the topic of nuclear deterrence and takes as its starting point a theoretical discussion of some of the concepts presented by the neorealist school of International Relations. In particular, this paper focuses on the work of Kenneth Waltz and John Mearsheimer, explaining terms like power, polarity and nuclear capacity. Secondly, in order to provide a kind of foil or counterpoint to the neorealist school, this dissertation presents the views of various authors from the field of Strategic Studies, particularly Bernard Brodie, Thomas Schelling, Lawrence Freedman, Colin Gray and Eugenio Diniz. Among other things, the investigation traces the evolution of nuclear strategic theory during the period of the Cold War. The dissertation also deals with issues related to the meaning of nuclear deterrence, seen here as power capability. Although the main focus of this research has to do with theoretical matters, the literature that was taken into consideration also allows one to branch out into the more practical field of politics. Thus, a good deal of the research centers on the prerequisites that have to be met before a nation can be considered a nuclear power and the meaning and practical implications of this. Above all, what needs clarification is whom or which countries India is able to deter with the nuclear or strategic power at its disposal. Therefore, after a brief presentation of the security landscape of the Indian subcontinent, which will allow one to gauge why India decided to go nuclear, the last chapter of this dissertation takes up the implications of nuclear deterrence as power capability, as it applies to India.

Full textAbstract:
This thesis examines and critiques conservative prescriptions for American strategic nuclear weapons policy between 1975 and 1987, with a specific focus on the programs and priorities of the Reagan Administration. The essay will use a tendency analysis approach to assess the conservative view within the context of overall the American nuclear debate. In the past decade, this debate has become increasingly polarized, with the various schools of thought moving further apart from one another on the central questions of American nuclear weapons policy.
The conservative view calls for the United States to secure nuclear escalation dominance over the Soviet Union, which conservatives argue, is essential to the success of American coercive diplomacy on behalf of those nations to which Washington extends the deterrent effect of its nuclear arsenal. During the Reagan administration, this has led to the pursuit of extensive counterforce capabilities, enhanced strategic ASW, and a renewed interest in strategic defence.
However, conservative policy prescriptions are based upon an analysis of American national security and nuclear weapons which has, as its principal focus, the military aspects of nuclear weapons policy. What is largely absent from the conservative analysis is a sense of how other factors, including Alliance relationships, diplomacy, and domestic considerations, can affect containment policy. The current conservative program is destined to be a policy failure, on its own terms, because it overestimates the political, economic, organizational, and technical capacities of the United States to field a nuclear posture capable of conducting extensive nuclear operations while holding American losses to tolerable levels.
The current strategic condition of Mutual Assured Destruction is very robust, and poses severe operational obstacles to the development of a high-confidence damage-limiting posture. As a matter of policy, the pursuit of escalation dominance has, as its focus, objectives that are too singular and inefficient for the proclivities of the United States in the post-Vietnam period.
If anything, the drive for nuclear superiority in the Reagan administration has contributed to the decline of American power, especially as manifested by the current budgetary and trade deficits. In a larger sense, conservative program may be ill-suited to a politico-strategic culture like that which exists in the United States. The substantial defence budgetary increases of the early Reagan period could have been employed far better if the Administration had set more marginal objectives for its strategic nuclear program. Instead, the Administration sought nuclear policy objectives which were unnecessary, operationally unreachable, politically divisive, and managerially unsound.
Reductions in defence spending seem to be a likely feature of the post-Reagan period. The paper concludes with two recommendations for American strategic policy. First, the United States should delegate more of the Western security burden to its allies, especially the nations of NATO-Europe, and Japan. Second, American nuclear planning should conform to a doctrine that stresses the capability to execute Limited Nuclear Options (LNOs). Such a posture might not be completely satisfying to either the liberal or conservative factions of the debate, but would seem to be the best way of maintaing a viable political coaltion which can sustain efficient, long-range planning for American strategic nuclear forces.Arts, Faculty of

This confrontational Russian behavior lends itself to the conduct of a case study of the international relations theory known as realism. This thesis analyzes Russian decision making on strategic missile defense and nuclear arms control from a realist perspective. Russia’s policies appear to be shaped by realist principles such as zero-sum calculations, the existence of an anarchic international system, and the continuing attempts to alter the balance of power to Moscow’s advantage. Moscow holds that U.S.-led ballistic missile defense (BMD) efforts could not only neutralize Russia’s nuclear deterrent, but upset strategic stability. Russia’s nuclear weapons serve a critical deterrent role and fulfill political purposes, so Moscow is highly resistant to nuclear arms reductions beyond those specified in the 2010 New START Treaty. Russia even seeks to modernize and expand its nuclear arsenal, but it will be constrained by economic realities. Despite these constraints, Russia’s great power ambitions hold potential security risks for NATO countries.

Full textAbstract:
The thesis follows a multidisciplinary approach, and adopts a critical methodology - rooted in techniques of discourse analysis and genealogy - in an effort to draw attention to the problems with continuing to assess Iran's strategic preferences within the parameters of ethnocentric paradigms of strategy. In this regard, it offers a critique of ontologies found in IR, strategic theory, and areas of Iranian Studies, and reconsiders the impact of Islam on Iran's nuclear trajectory based on a critical approach to understanding military jurisprudence from the perspectives of hermeneutics and epistemology. This thesis deconstructs some of the common portrayals of Iran's nuclear policies presented in today's academic and policy discourses. Specifically, it focuses on how the prospect of Iranian policies being guided by religious scholars is narrated by experts and commentators that confine Iranian strategic agency within one of two categories: Islamic fanaticism, or secular realism. Both of these approaches are situated within specific epistemological boundaries which the author critiques as the 'deterrence parameter'. In addition to deconstructing the prevailing narratives and discourses surrounding Iran's nuclear programme - and the epistemic parameters which discipline them - the author offers an Islamic framework as an alternative lens for analysing Iran's policies towards nuclear weapons and other weapons of mass destruction (WMD) if we are to assume that religion does have some impact on Iranian policy-making. This framework is formed of three interrelated levels: Qur'anic ontology, secondary sources, and theology. It also draws from previous instances where Muslim theologians and jurists have confronted weapons capable of mass destruction in light of concepts such as maslahah (public interest). The author applies this framework in assessing the verdicts of Islamic scholars on nuclear weapons and other WMD in an attempt to provide a counter-narrative for where Iran's strategic preferences emerge from and where they may go in the future.

The nuclear age provided U.S. soldiers and statesmen with unprecedented challenges. the U.S. military had to incorporate a weapon into strategic calculations without knowing whether the use of the weapon would be approved. Broad considerations of policy led President Dwight Eisenhower to formulate a policy that relied on nuclear weapons while fully realizing their destructive potential. Despite the belief that possession of nuclear weapons provided strategic superiority, the U.S. realized that such weapons were of little value. This realization did not stop planners from attempting to find ways to use nuclear weapons in Korea and Indochina.

Full textAbstract:
For over a decade, we have heard alarming statements about the spread of cyber weapons from senior policymakers and experts. Yet, the dynamics of cyber proliferation are still under-studied and under-theorized. This study offers a theoretical and empirical account of what causes the spread and restraint of cyber weapons and argues that the world is not at the brink of mass cyber proliferation. Whilst almost forty states are exploring and pursuing the development of cyber weapons, I indicate that only few have so far acquired a meaningful capability. This is due both to supply and demand factors. On the supply-side, most states have a latent capacity to develop relatively simple offensive cyber capabilities, but are unable to develop sophisticated cyber weapons. Moreover, the incentives for knowledge transfer and thus exporting offensive cyber capabilities between states are weak. On the demand-side, I show that national security considerations do not provide the best explanation of variance. Instead, domestic politics and prestige considerations are paramount. Moreover, and unlike nuclear proliferation, I argue that it is not the possession of cyber weapons but the intention of possession signalled through visible initiatives which matters. Ultimately, I note that cyber weapons can have strategic value - but only under certain conditions.

The supercritical carbon dioxide (S-C02) recompression cycle is a promising advanced power conversion cycle which couples well to numerous advanced nuclear reactor designs. This thesis investigates the dynamic simulation of, control strategies for, and selected transient results for an indirect S-CO2 recompression cycle. The cycle analyzed is a 600 MWth, highly recuperated, single shaft recompression power conversion cycle with a turbine inlet temperature of 6500C. The cycle features relatively high net efficiency (-47%) at relatively low heat addition temperatures, primarily due to efficient compression. The bottom of this cycle approaches (but in the steady state does not cross) carbon dioxide's critical point, where high fluid densities (-600 kg/m 3) allow efficient compression. Dynamic simulation of this cycle is complicated by its key features: single-shaft constant-speed turbomachinery, main and recompression compressor in parallel, operation of the main compressor inlet very close to the critical point, and rapid fluid property changes surrounding the critical point. A dynamic simulation and control code for gas-cooled Brayton Cycle reactor power conversion systems (PCS) has been significantly modified and enhanced to use supercritical carbon dioxide as the working fluid. These modifications include the incorporation of accurate yet fast fluid properties, more detailed modeling of turbomachinery performance, and rapid yet accurate calculation of heat exchange in printed circuit heat exchangers, even with rapid fluid property changes. Of particular significance are the methods devised to overcome convergence problems caused by compression near the critical point of C02, and the attendant large variations in properties in the main compressor, precooler and low temperature recuperator.
Coding innovations have made faster than real time simulation possible (on today's off the shelf hardware), which makes plant simulator and control applications feasible. This code was used to devise and investigate some of the major control strategies required to operate the cycle: high and low temperature control, three variations of turbine bypass, and inventory control. Using these strategies various transients were investigated including part-load operation, loss-of-load, loss of heat sink, over-power, and startup/shutdown.
