The Economics of Nuclear Power Programmes in the United Kingdom THE ECONOMICS OF NUCLEAR POWER PROGRAMMES IN THE UNITED KINGDOM Traditionally, decisions concerning investment in electricity-generating plant in the UK have been based on an evaluation of the direct costs involved, namely capital and operating costs. Examination of many of the wider-ranging impacts such as environmental implications and possible health effects have often been given somewhat less emphasis within the decision-making process. This book attempts to correct this imbalance by integrating estimates of various indirect costs associated with the operation of both coal-fired and nuclear-power generating capacity into a social cost analysis. Moreover, in an attempt to facilitate informed discussion ofsome ofthe more important issues relevant to the nuclear-power debate, this book also provides an interdisciplinary overview of several areas of legitimate public concern. In this respect, particular attention is paid to the technology involved in nuclear-reactor operation, the nature and development ofthe uranium market, the 'economics' ofthe reprocessing option, and the environmental impact of radioactive emissions from nuclear-power plant. It should be stressed that the author does not adopt either a pro- or anti­ nuclear standpoint, but rat her attempts to provide a means to raise the nuclear debate from an emotional to a more informed level. Peter LIoyd Jones is Research Fellow in the Department of Political Economy at the University of Aberdeen. He was employed as a consultant to the Electricity Consumers' Council for the Sizewell inquiry in 1982-3. He has contributed articles to Energy Economics, Financial Times Energy Reviews and the International Journal 0/ Environmental Studies.

First and foremost my supervisor, Professor David Pearce, who nursed this project through all aspects of the nuc1ear-power debate be fore guiding it to this final resting-place, and provided much needed motivation during numerous periods of doubt. In addition I have received invaluable assistance and advice from many individuals outside the confines of academia. In this respect special mention should be made ofDr P. M. S. Jones and his staff at the United Kingdom Atomic Energy Authority for guidance on technical matters, and Mr F. P. Jenkin of the Central Electricity Generating Board for helping to unravel the mysteries of the Board's accounting procedures. The nature of this work has necessitated a strong reliance on the computing facilities at Aberdeen University, and I should like to thank Terry Rourke ofthe Computing Centre for his time and help in the early stages of this research, at a time when my computing ability was sadly lacking; also David Rose of the Political Economy Department for introducing me to the intricacies of the Financial Corporate Planning System (FCS) package, and David Munro ofthe Computing Centre for not erasing my computer files despite several threats. From a financial point of view, thanks are due to the Social Science Research Council, my mother, and the Aberdeen Branch of the National Westminster Bank without whose support none ofthis would have been possible, and I hereby pledge to repay my considerable debt to the latter as so on as possible. In addition to these people I must thank a number of others whose contributions, although less direct, were equally valuable. In particular, Julia Bickerstaffe, Lynne Edwards and Guy Doyle for introducing me to many of the references used throughout the two-year period; also, my fellow postgraduates in the Department ofPolitical Economy both past and present for providing support and encouragement through informal discussions on many topics, and various flatmates for maintaining my vii viii Acknowledgements catTeine level at an optimum. Special mention should also be made ofDr Morag Horne, who bore the brunt of my ill-humour during the final stages of writing. Finally, to Mrs Winnie Sinclair, Mrs Phyl McKenzie and Miss Aileen Fraser I can only express the sincerest thanks for typing endless letters of inquiry and, of course, the final script.

  • Submission to the Nuclear Power Debate Personal Details Kept Confidential
    Submission to the Nuclear power debate Personal details kept confidential __________________________________________________________________________________________ Firstly I wish to say I have very little experience in nuclear energy but am well versed in the renewable energy one. What we need is a sound rational debate on the future energy requirements of Australia. The calls for cessation of nuclear investigations even before a debate begins clearly shows that emotion rather than facts are playing a part in trying to stop the debate. Future energy needs must be compliant to a sound strategy of consistent, persistent energy supply. This cannot come from wind or solar. Lets say for example a large blocking high pressure weather system sits over the Victorian, NSW land masses in late summer- autumn season. We will see low winds for anything up to a week, can the energy market from the other states support the energy needs of these states without coal or gas? I think not. France has a large investment in nuclear energy and charges their citizens around half as much for it than Germany. Sceptics complain about the costs of storage of waste, they do not suggest what is going to happen to all the costs to the environment when renewing of derelict solar panels and wind turbine infrastructure which is already reaching its use by dates. Sceptics also talk about the dangers of nuclear energy using Chernobyl, Three Mile Island and Fuklushima as examples. My goodness given that same rationale then we should have banned flight after the first plane accident or cars after the first car accident.

  • Ternary Fission and Quasi-Fission of Superheavy Nuclei and Giant Nuclear Systems
    June 17, 2010 18:24 Proceedings Trim Size: 9in x 6in zagrebaev_¯ssion_2010b TERNARY FISSION AND QUASI-FISSION OF SUPERHEAVY NUCLEI AND GIANT NUCLEAR SYSTEMS V.I. ZAGREBAEV, A.V. KARPOV Flerov Laboratory of Nuclear Reactions, JINR, Dubna, Moscow Region, Russia WALTER GREINER Frankfurt Institute for Advanced Studies, J.W. Goethe-UniversitÄat,Germany We found that a true ternary ¯ssion with formation of a heavy third fragment (a new kind of radioactivity) is quite possible for superheavy nuclei due to the strong shell e®ects leading to a three-body clusterization with the two doubly magic tin- like cores. The three-body quasi-¯ssion process could be even more pronounced for giant nuclear systems formed in collisions of heavy actinide nuclei. In this case a three-body clusterization might be proved experimentally by detection of two coincident lead-like fragments in low-energy U+U collisions. 1. Introduction Today the term \ternary ¯ssion" is commonly used to denote the process of formation of light charged particle accompanied ¯ssion 1. This is a rare process (less than 1%) relative to binary ¯ssion, see Fig. 1. As can be seen the probability of such a process decreases sharply with increasing mass number of the accompanied third particle. These light particles are emitted almost perpendicularly with respect to the ¯ssion axis (equatorial emission) 1. It is interpreted as an indication that the light ternary particles are emitted from the neck region and are accelerated by the Coulomb ¯elds of both heavy fragments. In contrast to such a process, the term \true ternary ¯ssion" is used for a simultaneous decay of a heavy nucleus into three fragments of not very di®erent mass 1.

Box 100 A-1400 Vienna, Austria COMPILATION AND EVALUATION OF FISSION YIELD NUCLEAR DATA IAEA, VIENNA, 2000 IAEA-TECDOC-1168 ISSN 1011–4289 © IAEA, 2000 Printed by the IAEA in Austria December 2000 FOREWORD Fission product yields are required at several stages of the nuclear fuel cycle and are therefore included in all large international data files for reactor calculations and related applications. Such files are maintained and disseminated by the Nuclear Data Section of the IAEA as a member of an international data centres network. Users of these data are from the fields of reactor design and operation, waste management and nuclear materials safeguards, all of which are essential parts of the IAEA programme. In the 1980s, the number of measured fission yields increased so drastically that the manpower available for evaluating them to meet specific user needs was insufficient. To cope with this task, it was concluded in several meetings on fission product nuclear data, some of them convened by the IAEA, that international co-operation was required, and an IAEA co-ordinated research project (CRP) was recommended. This recommendation was endorsed by the International Nuclear Data Committee, an advisory body for the nuclear data programme of the IAEA. As a consequence, the CRP on the Compilation and Evaluation of Fission Yield Nuclear Data was initiated in 1991, after its scope, objectives and tasks had been defined by a preparatory meeting.

  • Properties of Selected Radioisotopes
    CASE FILE COPY NASA SP-7031 Properties of Selected Radioisotopes A Bibliography PART I: UNCLASSIFIED LITERATURE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION NASA SP-7031 PROPERTIES OF SELECTED RADIOISOTOPES A Bibliography Part I: Unclassified Literature A selection of annotated references to technical papers, journal articles, and books This bibliography was compiled and edited by DALE HARRIS and JOSEPH EPSTEIN Goddard Space Flight Center Greenbelt, Maryland Scientific and Technical Information Division / OFFICE OF TECHNOLOGY UTILIZATION 1968 USP. NATIONAL AERONAUTICS AND SPACE ADMINISTRATION Washington, D.C. PREFACE The increasing interest in the application of substantial quantities of radioisotopes for propulsion, energy conversion, and various other thermal concepts emphasizes a need for the most recent and most accurate information available describing the nuclear, chemical, and physical properties of these isotopes. A substantial amount of progress has been achieved in recent years in refining old and developing new techniques of measurement of the properties quoted, and isotope processing. This has resulted in a broad technological base from which both the material and information about the material is available. Un- fortunately, it has also resulted in a multiplicity of sources so that information and data are either untimely or present properties without adequately identifying the measurement techniques or describing the quality of material used. The purpose of this document is to make available, in a single reference, an annotated bibliography and sets of properties for nine of the more attractive isotopes available for use in power production. Part I contains all the unclassified information that was available in the literature surveyed. Part II is the classified counterpart to Part I.

  • Civilian Nuclear Waste Disposal
    Civilian Nuclear Waste Disposal (name redacted) Specialist in Energy Policy January 11, 2016 Congressional Research Service 7-.... www.crs.gov RL33461 Civilian Nuclear Waste Disposal Summary Management of civilian radioactive waste has posed difficult issues for Congress since the beginning of the nuclear power industry in the 1950s. Federal policy is based on the premise that nuclear waste can be disposed of safely, but proposed storage and disposal facilities have frequently been challenged on safety, health, and environmental grounds. Although civilian radioactive waste encompasses a wide range of materials, most of the current debate focuses on highly radioactive spent fuel from nuclear power plants. The United States currently has no disposal facility for spent nuclear fuel. The Nuclear Waste Policy Act of 1982 (NWPA) calls for disposal of spent nuclear fuel in a deep geologic repository. NWPA established the Office of Civilian Radioactive Waste Management (OCRWM) in the Department of Energy (DOE) to develop such a repository, which would be licensed by the Nuclear Regulatory Commission (NRC). Amendments to NWPA in 1987 restricted DOE’s repository site studies to Yucca Mountain in Nevada. DOE submitted a license application for the proposed Yucca Mountain repository to NRC on June 3, 2008. The state of Nevada strongly opposes the Yucca Mountain project, citing excessive water infiltration, earthquakes, volcanoes, human intrusion, and other technical issues. The Obama Administration “has determined that developing the Yucca Mountain repository is not a workable option and the Nation needs a different solution for nuclear waste disposal,” according to the DOE FY2011 budget justification. As a result, no funding for Yucca Mountain, OCRWM, or NRC licensing was requested or provided for FY2011 or subsequent years.

  • Kiejziewicz the Nuclear Technology Debate Returns
    TRANSMISSIONS: THE JOURNAL OF FILM AND MEDIA STUDIES 2017, VOL.2, NO. 1, PP. 117-131. Agnieszka Kiejziewicz Jagiellonian University The nuclear technology debate returns. Narratives about nuclear power in post-Fukushima Japanese films Abstract The presented article revolves around the widespread debate on the Fukushima catastrophe in Japanese cinematography and the artists’ responses to the incident. They give the viewers clues on how to understand the reasons and results of the Fukushima nuclear disaster, as well as how to perceive nuclear technology after the catastrophe. The author analyses the chosen post-Fukushima films, points out the recurring depictions, and deliberates on the ways of presenting nuclear power. The analysis starts with a brief comparison of post-Hiroshima and post-Fukushima cinematography. The author then focuses on activists’ art in the form of anti-nuclear agitation (Nuclear Japan, 2014 by Hiroyuki Kawai) and pictures that can be classified as shōshimin-eiga: Kebo no kuni (The Land of Hope, 2012) and Leji (Homeland, 2014). The third part of the article puts emphasis on the description of the catastrophe as a “new beginning”, as Takashi Murakami presents it in Mememe no kurage (Jellyfish Eye, 2013). The debate on nuclear technology also appears in the remake of the story about the best-known Japanese monster, Godzilla, reactivated by Hideaki Anno in the post-Fukushima film Shin Gojira (New Godzilla, 2016). The last part of the paper presents the Western point of view and covers analysis of films such as Alain de Halleux’s Welcome to Fukushima (2013), Doris Dörrie’s Grüße aus Fukushima (Fukushima, My Love, 2016) or Matteo Gagliardi’s Fukushima: A Nuclear Story (2015).
