This is a survey of current developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. National research and development plans are also summarized. The actinide-fuelled critical reactors are associated with control problems, since they tend to have a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. Current thinking is turning to accelerator-driven subcritical systems for the transmutation of actinides. The volume draws the conclusion that the various systems proposed are technically feasible, even though not yet technically mature. The book presents a summary and evaluation of all relevant possibilities for burning surplus plutonium, presented by experts from a variety of different disciplines and interests, including the defence establishment. The obvious issue - the non-proliferation of nuclear weapons - is vital, but the matter represents a complex technological challenge that also requires an assessment in economic terms.
Chemical Reactor Design and Operation K. R. Westerterp, W. P. M. van Swaaij and A. A. C. M. Beenackers Chemical Reaction Engineering Laboratories, Twente University of Technology, Enschede, The Netherlands This is a comprehensive handbook on the design and operation of chemical reactors which are vital elements in every manufacturing process. The book offers an introduction to the modern literature and covers in depth the relevant theory of chemical reactors. The theory is illustrated by numerous worked examples typical to chemical reaction engineering practice in research, development, design and operation. The examples range from fine chemicals to large scale production and from water purification to metallurgical processes, commencing with simple homogenous model reactors and then moving to the complicated, multi-phase, heterogeneous reactors met with in reality. All the examples are based on the industrial experience of the authors. Much effort is dedicated to the behaviour of reactors in practice and to the capacity, yield and selectivity of the reactor. The book is thoroughly indexed and cross-referenced. This edition will be particularly useful to undergraduate and graduate students studying chemical reactors. Contents Fundamentals of chemical reactor calculations Model reactors: single reactions, isothermal single phase reactor calculations Model reactors: multiple reactions, isothermal single phase reactors Residence time distribution and mixing in continuous flow reactors Influence of micromixing on chemical reactions The role of the heat effect in model reactors Multi-phase reactors, single reactions Multi-phase reactors, multiple reactions Heat effects in multi-phase reactors The authors: The authors have accumulated a long experience both in fine chemicals and in the petrochemicals industry, in Europe as well as abroad. Currently they are jointly responsible for the research work in chemical reaction engineering and process development at Twente University. Several new reactor types and new processes have been developed at their institute and present research interests include gasification, fluidization and gas--liquid reactors, three-phase reactors, high-pressure technology in chemical reaction engineering, thermal behaviour of heterogeneous reactors and computer design and economic evaluation of reaction units and chemical plants.
This textbook accommodates the two divergent developmental paths which have become solidly established in the field of fusion energy: the process of sequential tokamak development toward a prototype and the need for a more fundamental and integrative research approach before costly design choices are made.Emphasis is placed on the development of physically coherent and mathematically clear characterizations of the scientific and technological foundations of fusion energy which are specifically suitable for a first course on the subject. Of interest, therefore, are selected aspects of nuclear physics, electromagnetics, plasma physics, reaction dynamics, materials science, and engineering systems, all brought together to form an integrated perspective on nuclear fusion and its practical utilization.The book identifies several distinct themes. The first is concerned with preliminary and introductory topics which relate to the basic and relevant physical processes associated with nuclear fusion. Then, the authors undertake an analysis of magnetically confined, inertially confined, and low-temperature fusion energy concepts. Subsequently, they introduce the important blanket domains surrounding the fusion core and discuss synergetic fusion-fission systems. Finally, they consider selected conceptual and technological subjects germane to the continuing development of fusion energy systems.

This book presents a thermodynamic and economic analysis of gas-gas systems in power plants, including combined heat and power systems, combined cooling, heat and power systems, hydrogen production facilities and compressed energy storage system. A configuration for high-temperature gas-cooled nuclear reactor is also used as a heat source for the cycle. The book compares different technologies, such as gas-steam and gas-gas systems, using optimized cases. It presents mathematical models that return optimal thermodynamic parameters of the cycles, and applies a novel continuous-time model in order to perform an economic analysis as well. This book utilizes numerous illustrations and worked examples to thoroughly explain the technologies discussed, making it relevant for researchers, market analysts, decision makers, power engineers and students alike.
Intended primarily for undergraduate chemical-engineering students, this book also includes material which bridges the gap between undergraduate and graduate requirements. The introduction contains a listing of the principal types of reactors employed in the chemical industry, with diagrams and examples of their use. There is then a brief exploration of the concepts employed in later sections for modelling and sizing reactors, followed by basic information on stoichiometry and thermodynamics, and the kinetics of homogeneous and catalyzed reactions. Subsequent chapters are devoted to reactor sizing and modelling in some simple situations, and more detailed coverage of the design and operation of the principal reactor types.
We need energy to warm and light our homes, to power our transport and communications, and to support our manufacturing industries. Can we obtain enough energy to satisfy the needs of a rapidly increasing world population without, at the same time, devastating the earth? Is nuclear power the way to do this?This book surveys available energy sources and their effects on the environment in the context of moral imperatives and political realities.

This open access book discusses the eroding economics of nuclear power for electricity generation as well as technical, legal, and political acceptance issues. The use of nuclear power for electricity generation is still a heavily disputed issue. Aside from technical risks, safety issues, and the unsolved problem of nuclear waste disposal, the economic performance is currently a major barrier. In recent years, the costs have skyrocketed especially in the European countries and North America. At the same time, the costs of alternatives such as photovoltaics and wind power have significantly decreased.
This textbook introduces energy utilisation. It outlines energy balances - which are determined by the fundamental laws of thermodynamics-, the fundamentals of atomic and nuclear mechanisms, the laws of fluid mechanics and electromagnetism. The technologies which stem from these mechanisms, including steam power plants, solar and wind energy systems, hydrodynamic power, biomass and geothermal energy systems, are all discussed. Prospects for future projects, such as nuclear fusion, fuel cells, and smart energy concepts are presented, as well as the role of energy balances in relation to climate engineering. Opportunities and Limits of Energy Utilisation will be of interest to graduate students, as well as researchers, lecturers, industry engineers. It provides numerous examples, problems and solutions, making it particularly relevant to students looking for a thorough understanding of the fundamentals of advanced energy technologies.
This book covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide. In particular, nuclear transmutation technology has been drawing significant attention after the accident. This publication is timely with the following highlights: 1) Development of accelerator-driven systems (ADSs), which is a brand-new reactor concept for transmutation of highly radioactive wastes; 2) Nuclear reactor systems from the point of view of the nuclear fuel cycle. How to reduce nuclear wastes or how to treat them including the debris from TEPCO s Fukushima nuclear power stations is discussed; and 3) Environmental radioactivity, radioactive waste treatment and geological disposal policy. State-of-the-art technologies for overall back-end issues of the nuclear fuel cycle as well as the technologies of transmutation are presented here. The chapter authors are actively involved in the development of ADSs and transmutation-related technologies. The future of the back-end issues in Japan is very uncertain after the accident at the Fukushima Daiichi NPP and this book provides an opportunity for readers to consider the future direction of those issues."

Engaging with stakeholders is an essential part of any complete nuclear programme. Involving stakeholders in decision making processes, even those stakeholder groups that do not have a direct role in making those decisions, can enhance public confidence in the application of nuclear science and technology and strengthen communication among the key organizations in a nuclear programme. This publication provides theoretical and practical guidance on the development and implementation of stakeholder engagement programmes and activities. The key principles of stakeholder engagement are identified in it. It also includes tools such as templates to help establish a stakeholder engagement programme and identify associated activities, including tools for stakeholder analysis. The guidance provided can be further developed and adjusted to each specific type of facility, moment in its life cycle, and/or the group of stakeholders with which to engage. The publication demonstrates the importance of stakeholder engagement throughout the life cycle of all nuclear facilities, including operating and new reactors, all aspects of the nuclear fuel cycle, from uranium mining to spent fuel and radioactive waste management, decommissioning, and non-power applications.
The book offers the first systematic account of Iran's foreign policy following the nuclear agreement (JCPOA) of July 14, 2015. The author evaluates in what ways the JCPOA, in conjunction with the dramatic changes taking shape in the international order, have affected Iran's foreign policy. Known as Normalizers, the moderate leadership under President Hassan Rouhani had planned to normalize Iran's foreign relations by curtailing terrorism and reintegrate Iran into the community of nations. Their hardline opponents, the Principalists, rejected the JCPOA as a tool of subjection to the West and insisted on exporting the Islamist revolution, a source of much destabilization and terror in the region and beyond. The project also analyzes the struggle between Normalizers and their hardline opponents with regards to global and regional issues and Iran's foreign policy towards global powers including the U.S., Russia, EU, and regional countries including Iraq, Syria, Israel, Saudi Arabia and Turkey.

Since then, the body of knowledge in the field of nuclear security has grown substantially and the IAEA Nuclear Security Series has expanded to cover more topics. The current publication takes into account the latest IAEA guidance, as well as feedback from the International Nuclear Security Education Network (INSEN) community and other international experts. The publication can be used by university curriculum developers as well as faculty and instructors from institutions that are implementing or considering educational programmes in nuclear security.
This book provides a history of emergency planning with respect to nuclear power plant accidents from the 1950's to the 2000's. It gives an overview of essential concepts that a working emergency planner should know, including brief overviews of the health physics and plant engineering that applies to emergency planning. Each chapter covers topics unique to radiological planning that distinguish it from planning for natural disasters. Some of the topics include processes that damage fuel, reactor source terms, basic dispersion theory, protective measures for the public and emergency worker, environmental surveys, and the essential elements of a drill and exercise program. Emergency Planning for Nuclear Power Plants is not intended as a guide to meeting regulatory requirements but provides an understanding of the essential concepts and language of radiological planning, so the planner can apply those concepts to their particular situation.
The identification and assessment of threats provides an essential basis for the selection, design, and implementation of nuclear security measures. For nuclear material and other radioactive material that is under regulatory control, and associated facilities and activities, the results of this identification and assessment are expressed as a design basis threat or representative threat statement describing the intentions and capabilities of potential adversaries against which the materials and associated facilities and activities are to be protected. An Implementing Guide was issued in 2009 under the title of Development, Use and Maintenance of the Design Basis Threat which was updated and revised. The result of this revision is the current publication. It provides a step?bystep methodology for conducting a national nuclear security threat assessment including both physical and computer security aspects, and for the development, use and maintenance of design basis threats and representative threat statements.
Introduces Novel Applications for Solving Neutron Transport Equations While deemed nonessential in the past, fractional calculus is now gaining momentum in the science and engineering community. Various disciplines have discovered that realistic models of physical phenomenon can be achieved with fractional calculus and are using them in numerous ways. Since fractional calculus represents a reactor more closely than classical integer order calculus, Fractional Calculus with Applications for Nuclear Reactor Dynamics focuses on the application of fractional calculus to describe the physical behavior of nuclear reactors. It applies fractional calculus to incorporate the mathematical methods used to analyze the diffusion theory model of neutron transport and explains the role of neutron transport in reactor theory. The author discusses fractional calculus and the numerical solution for fractional neutron point kinetic equation (FNPKE), introduces the technique for efficient and accurate numerical computation for FNPKE with different values of reactivity, and analyzes the fractional neutron point kinetic (FNPK) model for the dynamic behavior of neutron motion. The book begins with an overview of nuclear reactors, explains how nuclear energy is extracted from reactors, and explores the behavior of neutron density using reactivity functions. It also demonstrates the applicability of the Haar wavelet method and introduces the neutron diffusion concept to aid readers in understanding the complex behavior of average neutron motion. This text: Applies the effective analytical and numerical methods to obtain the solution for the NDE Determines the numerical solution for one-group delayed neutron FNPKE by the explicit finite difference method Provides the numerical solution for classical as well as fractional neutron point kinetic equations Proposes the Haar wavelet operational method (HWOM) to obtain the numerical approximate solution of the neutron point kinetic equation, and more Fractional Calculus with Applications for Nuclear Reactor Dynamics thoroughly and systematically presents the concepts of fractional calculus and emphasizes the relevance of its application to the nuclear reactor.
This revised second edition of a popular handbook for engineers describes the important relationship between high-energy radiation environments, electronic device physics and materials. It is a straightforward account of the problems which arise when high-energy radiation bombards matter and of engineering methods for solving those problems. Radiation effects are a problem encountered in the use of highly engineered materials such as semiconductors, optics and polymers. The finely-tuned properties of these materials may change drastically when exposed to a radiation environment such as a bean of X-rays or electrons, the space environment or the 'hadrons' in CERN's new collider. All of these environments and several more are described. The impact of these environments on microelectronics in computing, data processing and communication is the core of this book (highlighted in chapters on MOS and optical devices). While unashamedly oriented to the engineer-designer and manager, with descriptions in a highly readable form, there is no compromise in physical accuracy when describing high-energy radiation and the effects it produces, such as electronic failure, colour centres and the decay of strength. A great breadth of technical data, needed to make predictions on the spot, is presented, with literature references needed for further research and also a compendium of websites which have been tested and used by authors.
Accurate uranium analysis, and particularly for isotope measurements, is essential in many fields, including environmental studies, geology, hydrogeology, the nuclear industry, health physics, and homeland security. Nevertheless, only a few scientific books are dedicated to uranium in general and analytical chemistry aspects in particular. Analytical Chemistry of Uranium: Environmental, Forensic, Nuclear, and Toxicological Applications covers the fascinating advances in the field of analytical chemistry of uranium. Exploring a broad range of topics, the book focuses on the analytical aspects of industrial processes that involve uranium, its presence in the environment, health and biological implications of exposure to uranium compounds, and nuclear forensics. Topics include: Examples of procedures used to characterize uranium in environmental samples of soil, sediments, vegetation, water, and air Analytical methods used to examine the rigorous specifications of uranium and its compounds deployed in the nuclear fuel cycle Health aspects of exposure to uranium and the bioassays used for exposure assessment Up-to-date analytical techniques used in nuclear forensics for safeguards in support of non-proliferation, including single particle characterization Each chapter includes an overview of the topic and several examples to demonstrate the analytical procedures. This is followed by sample preparation, separation and purification techniques where necessary. The book supplies readers with a solid understanding of the analytical chemistry approach used today for characterizing the different facets of uranium, providing a good starting point for further investigation into this important element.
Recent upheaval in the global energy system - dramatic increases in demand led largely by developing countries, significant decreases in supply as a result of local or regional conflicts, and the growing nexus between the burning of hydrocarbons and climate change - has unsettled long-held notions of energy security. For many years, transatlantic cooperation helped undergird the system's stability, but Europe and North America have drifted apart in several key ways, potentially undermining the search for energy sufficiency, surety, and sustainability. Will the transatlantic partners continue on separate paths in the face of dramatic change in the global energy system, or does the breadth and depth of the challenges they confront compel them to work more closely together? In this edited volume, experts from across Europe and North America - including advisors to the executive and legislative branches of both the EU and the United States, to senior military commanders, and to major international organizations and companies - examine the most salient facets of the transatlantic energy relationship and discern whether that relationship is characterized by growing convergence or divergence. This book was based on a special issue of the Journal of Transatlantic Studies.
This book collects together four essays by the very well-known academic Gilbert Murray that were first presented between 1914 and 1939. The author seeks to present a statement of his profound belief in ethics and disbelief in revelational religions. The philosophy of this great thinker is accessibly written while it addresses deep questions of the nature of morality and the basis of religions. This collection was first published in 1940.
This volume brings together analyses of key domestic, foreign and security policy issues during the Putin and Medvedev administrations. Indeed, the chapters demonstrate the extent to which domestic and foreign policy issues are inextricably linked, in particular in the domain of security, whether 'hard' or 'soft'. Internal debates regarding Russia's trajectory, including issues of national identity; economic modernisation, human rights and democracy, continue to be at the forefront of concern. Moreover, these debates are intimately connected to Russia's self-image and the image therefore, that it wishes to project in the wider world. The debates focus on Russia as 'energy superpower'; as one of the 'BRICS'; as an Eurasian landbridge, or a window on the Asia-Pacific. Such debates are a constant reminder of the uncertainty surrounding Russia's future path. This book expresses these uncertainties which range from the role of nuclear weapons and energy to critiques of Russia's approach to concepts such as sovereignty and self-determination; the fight against terrorism, insurgency, and the role of Islam within and without. Russia may have left the 'chaos' of the Yeltsin years behind but, as we move into 'Putin 3.0', the concerns of these chapters will remain critical both to Russia itself, and to Russia's relations with the wider world. This book was published as a special issue of Europe-Asia Studies. |
