From World War II to the present day, nuclear power has remained a controversial topic in the public eye. In the wake of ongoing debates about energy and the environment, policymakers and laypeople alike are once more asking the questions posed by countless others over the decades: What actually happens in a nuclear power plant? Can we truly trust nuclear energy to be safe and reliable? Where does all that radiation and waste go? This book explains everything you would want to know about nuclear power in a compelling and accessible way. Split into three parts, it walks readers through the basics of nuclear physics and radioactivity; the history of nuclear power usage, including the most important events and disasters; the science and engineering behind nuclear power plants; the politics and policies of various nations; and finally, the long-term societal impact of such technology, from uranium mining and proliferation to final disposal. Featured along the way are dozens of behind-the-scenes, full-color images of nuclear facilities. Written in a nontechnical style with minimal equations, this book will appeal to lay readers, policymakers and professionals looking to acquire a well-rounded view about this complex subject.

ssei Gelegenheit der Vorarbeiten zu einem Colleg uber Spektralanalyse wurde mir der Mangel an einem Lehrbuch uber diesen Abschnitt der Physik aufs Neue fuhlbar, nachdem ich ihn schon fruher bei eigenen Untersuchungen sehr empfunden hatte. In unseren Lehrbuchern der allgemeinen Physik wird dieses so interessante Gebiet ausserordentlich stiefmutterlich behandelt, die neueren Versuchsmethoden und Resultate finden sich fast nirgends angegeben, und die enormen Fortschritte, welche die Spektralanalyse in den letzten 15 Jahren - nament- lich durch englische Forscher - gemacht hat, bleiben meist unerwahnt. Von den speciellen Werken uber Spektralanalyse, deren es eine recht grosse Anzahl giebt, verfolgen die meisten den Zweck, in ganz popularer Form den Gegenstand zu behan- deln; in dieser Richtung hat Roscoe Ausgezeichnetes geleistet. Andere Werke sind zwar wissenschaftlicher gehalten, aber sie be- tonen dann nur einzelne Capitel oder einzelne Richtungen der Spektralanalyse; so hat das sehr empfehlenswerthe Buch von H. W. Vogel nur die praktische Analyse, namentlich die durch Absorptionsspektren im Auge. Auch die sehr starke, neueste Auflage der Schellen'schen Spektralanalyse lasst recht viel zu wunschen ubrig. Es bleibt daher einem Jeden, der sich eingehend mit der Sache beschaftigen will, nichts anderes ubrig als selbst an die Quellen zu gehen und die Tausende von Abhandlungen, die in zahllosen Zeitschriften verstreut sind, zu studiren. Als nun auch ich mich dieser nicht kleinen Arbeit unterzog, schien es mir doch zweckmassig, sie nicht nur fur mich zu unternehmen, sondern sie auch fur Andere verwerthbar zu machen, VI VORWORT.

Reliable methods for estimating the cost of a radioactive waste disposal programme are crucial to ensure that the necessary funding for completing the disposal programme is available. Estimating the cost for disposal is however a challenging and complex task. Disposal programmes themselves are complex and long-term undertakings and conditions can be expected to change significantly over the time-span during which a disposal programme is developed and implemented. This publication provides Member States with guidance on how to develop cost estimates for a disposal programme and on how to establish funding mechanisms. It will help readers in becoming informed clients by familiarizing themselves with the approaches and complexities in cost estimates and funding mechanisms for disposal. The publication is applicable to all waste categories and both near surface and geological disposal. It contains relevant examples and case studies from national programmes. The cost figures are intended to give an indication of the possible cost of certain parts or aspects of the disposal programme rather than to compare different disposal programmes' costs.

The publication focuses on radioecologjcal experience and data acquired and lessons learned in Japan following the nuclear accident at the Fukushima Daiichi nuclear power plant in March 2011. The publication brings together outcomes of the extensive studies, done by Japanese scientists and their colleagues from other countries, on characterization of radioecological transfer parameters in the terrestrial and aquatic environments of Japan affected by radionuclides released in the accident. The Japan specific data are systematically presented and compared to the global experience gained from the earlier nuclear accidents, military or industrial activities. Climate, landscape, agriculture and food processing practices, lifestyle and national dietary customs are shown as factors influencing transfer of radionuclides through the environment and human food chains. The publication summarizes country specific experience and puts it into existing global radioecological contexts.

Nuclear physics began long before the identification of fundamental particles, with J. J. Thomson's discovery of the electron at the end of the 19th century, which implied the existence of a positive charge in the atom to make it neutral. In this Very Short Introduction Frank Close gives an account of how this area of physics has progressed, including the recognition of how heavy nuclei are built up in the cores of stars and in supernovae, the identification of quarks and gluons, and the development of quantum chromodynamics (QCD). Exploring key concepts such as the stability of different configurations of protons and neutrons in nuclei, Frank Close shows how nuclear physics brings the physics of the stars to Earth and provides us with important applications, particularly in medicine. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

There have been many recent discussions of the 'replication crisis' in psychology and other social sciences. This has been attributed, in part, to the fact that researchers hesitate to submit null results and journals fail to publish such results. In this book Allan Franklin and Ronald Laymon analyze what constitutes a null result and present evidence, covering a 400-year history, that null results play significant roles in physics.

This publication presents the latest update to the INPRO methodology for Nuclear Energy Systems sustainability assessment in the area of waste management and reflects detailed discussions held at an IAEA technical meeting. Waste generated by nuclear energy systems and considered in this publication includes all classes and categories of waste from nuclear power plants and nuclear fuel cycle facilities over the course of normal operations and anticipated operational occurrences. It is anticipated that the information presented in this and other INPRO publications, for example IAEA Nuclear Energy Series No. NG-T-3.12, will assist in the identification of areas for improvement in nuclear energy systems.

A deeper understanding of neutrinos, with the goal to reveal their nature and exact role within particle physics, is at the frontier of current research. This book reviews the field in a concise fashion and highlights the most pressing issues and areas of strongest topical interest. It provides a clear, self-contained, and logical treatment of the fundamental physics aspects, appropriate for graduate students. Starting with the relevant basics of the SM, neutrinos are introduced, and the quantum mechanical effect of oscillations is explained in detail. A strong focus is then set on the phenomenon of lepton number violation, especially in 0nbb decay, as the crucial probe to understand the nature of neutrinos. The role of neutrinos in astrophysics, expected to be of increasing importance for future research, is then described. Finally, models to explain the neutrino properties are outlined. The central theme of the book is the nature of neutrino masses and the above topics will revolve around this issue.
