All aspects of this costly, highly sensitive and potentially hazardous operation are discussed and presented. Topics include: finance and policy; regulation, compliance and international co-operation; liabilities management; public perception, innovation; learning from other industries; contract mangement; implementation; technical visits; monitoring; benchmarking and waste management.

The International Atomic Energy Agency estimates that nuclear power generation facilities produce about 200,000 cubic meters of low and intermediate-level waste each year. Vital medical procedures, industrial processes and basic science research also produce significant quantities of waste. All of this waste must be shielded from the population for extended periods of time. Finding suitable locations for disposal facilities is beset by two main problems: community responses to siting proposals are generally antagonistic and, as a result, governments have tended to be reactive in their policy-making. Decision-making and Radioactive Waste Disposal explores these issues utilizing a linear narrative case study approach that critically examines key stakeholder interactions in order to explain how siting decisions for low level waste disposal are made. Five countries are featured: the US, Australia, Spain, South Korea and Switzerland. This book seeks to establish an understanding of the political, economic, environmental, legal and social dimensions of siting across those countries. This valuable resource fills a gap in the literature and provides recommendations for future disposal facility siting efforts. The book will be of interest to students and scholars of environmental law, justice, management, politics, energy and security policy as well as decision-makers in government and industry.

Detailing the estimation and perception of nuclear risk, this book follows military and civilian nuclear accidents, plus the systems put in place by national and international authorities for recording and analyzing feedback. Prevention and anticipation being the best defenses against a nuclear accident, the authorities have also categorized the different types of accidents, and are doing research to better understand and control them. In light of this, this book shows how the authorities take practical measures to protect neighboring populations and limit radioactive contamination of the environment. France s experience in this arena is well-documented and a chapter of this book is devoted to the fight against terrorist attacks in the nuclear field. Nuclear Accidents is based on scientifically-recognized publications, as well as on reports from the various countries concerned, and the national and international organizations competent in this field (IAEA, WHO, UNSCEAR, IRSN, etc.).

The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This revised and updated 4th edition explores the challenges that faced the scientists and engineers of the Manhattan Project. It gives a clear introduction to fission weapons at the level of an upper-year undergraduate physics student by examining the details of nuclear reactions, their energy release, analytic and numerical models of the fission process, how critical masses can be estimated, how fissile materials are produced, and what factors complicate bomb design. An extensive list of references and a number of exercises for self-study are included. Revisions to this fourth edition include many upgrades and new sections. Improvements are made to, among other things, the analysis of the physics of the fission barrier, the time-dependent simulation of the explosion of a nuclear weapon, and the discussion of tamped bomb cores. New sections cover, for example, composite bomb cores, approximate methods for various of the calculations presented, and the physics of the polonium-beryllium "neutron initiators" used to trigger the bombs. The author delivers in this book an unparalleled, clear and comprehensive treatment of the physics behind the Manhattan project.

Fusion neutron sources have many important practical uses, such as irradiation testing of materials and components, facilitating the production of various isotopes such as tritium, driving subcritical cores, characterizing spent nuclear fuel, and manufacturing medical isotopes. All these applications can be potentially improved by achieving higher neutron yields and fluxes in compact fusion neutron sources (CFNSs). This publication is a compilation arising from an IAEA coordinated research project on this topic and presents the project's main results and findings with the aim of supporting stakeholders in the development of CFNSs in the transition from conceptual to engineering design.

Management systems play an important role in the success of a nuclear power programme. Recognizing that their development poses a number of questions, this publication aims to share experiences of regulatory bodies and owner operator organizations in developing management systems consistent with the main activities planned from inception of these organizations to construction of a nuclear power plant, whilst prioritizing safety.

This book describes repository solutions for all types of radioactive waste and residues in different geotechnical repository structures. The focus is initially on existing or planned final disposal sites in Germany and the process of finding sites. However, international comparisons are drawn, especially to locations in the US. This affects both the repository structures and the legal requirements. The radioactive substances considered include residues from uranium ore processing, as well as low and intermediate level radioactive waste up to heat generating, high level radioactive wastes, such as spent fuel and vitrified waste from reprocessing. In order to evaluate the repository structures and their inventories, a dimensionless radiotoxicity index Ai / Fi [activity of radionuclide quantity (Ai) related to the exemption limit of radionuclide (Fi)] has been introduced. This gives the reader a well-founded overview of the degree of inconsistency in the handling of safety requirements for the respective geotechnical environmental structures. This creates the necessary transparency on this issue, which has not been previously available and is required by stakeholders today. The long-term security, the duration of the observation period and the certainty of the safety prognosis are also discussed in the book as well as the participation of subsequent generations in current and possible future repositories. This is vital as nuclear energy will continue to be used worldwide in the long term. The international repository projects presented have all been subjected to the same evaluation criteria. This applies both to existing operational project as well as those about to be commissioned and the processes for seeking locations. Special attention has been paid to monitoring, both operational and long-term monitoring. This broad range of topics makes this book a very valuable read for both the interested public and the professional world.

Using primarily Russian sources, this book explains the political and economic aspects of nuclear power. The nuclear fuel cycle is described, from the mining of natural uranium to the ultimate power generation, and to reprocessing to produce plutonium which is essential for both electricity generation and for weapons production. Historical aspects of nuclear developments in Germany, the USA, India, China and the Soviet Union are also considered and explained. The book then proceeds to argue that Russia is more powerful today in its nuclear weapons system and delivery than ever before, and that it is precisely this which has provoked President Trump to cancel the strategic nuclear weapons reduction treaty.

This book describes the four Nuclear Security Summits held over 2010-2016 at the initiative of U.S. President Barack Obama. The author draws upon his unique vantage point as a participant in the Summits, exclusive interviews with practitioners, and access to primary documents, to write an engaging history of the NSS and of nuclear security in general. The story of the NSS is also in part the story of multilateral nuclear forums, which have sprung up regularly since the dawn of the nuclear age to address perceived nuclear dangers. The success of these Summits in addressing the threat of nuclear terrorism holds important lessons for the design and work of nuclear forums today and into the future. The author presents a new approach to assessing 'international learning' that has important implications for the design of multilateral forums and updates the Cold War areas of nuclear knowledge being 'learnt' in the light of the NSS experience and other recent developments. This work will be of interest to scholars and practitioners in security studies, nuclear history, and International Relations.

X ray, neutron and gamma radiography have been widely used by industry as non-destructive testing methods for quality control and to assess the safety and integrity of structures. Such techniques use intense, human-made radiation sources in the laboratory and at industrial sites. Muons are relatively massive elementary particles produced naturally by cosmic rays, and which may be used as a highly penetrating, non-destructive probe. Muon imaging is therefore an attractive alternative for certain applications. This publication describes some of the main muon imaging techniques, the detector types involved, and a wide variety of applications that have been identified from examination of modern and ancient built environments, volcanology, industry to nuclear security and safeguards. This publication is expected to be of use to all those individuals working in industry and academia with an interest in muon imaging.

This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments.

This INSAG report defines in detail the independence needed in the regulatory decision making process and how to meet the potential challenges to that independence. Thus, the report identifies a number of measures that need to be implemented at different levels to promote and protect independence in the regulatory decision making process. The basic principles have to be embedded into the legal framework and followed up by systematic quality management of regulatory processes and activities.

This publication documents the results of an IAEA coordinated research project (CRP)on the application of computational fluid dynamics (CFD) codes for nuclear power plant design. The main objective was to benchmark CFD codes, model options and methods against CFD experimental data under single phase flow conditions. This publication summarizes the current capabilities and applications of CFD codes, and their present qualification level, with respect to nuclear power plant design requirements. It is not intended to be comprehensive, focusing instead on international experience in the practical application of these tools in designing nuclear power plant components and systems. The guidance in this publication is based on inputs provided by international nuclear industry experts directly involved in nuclear power plant design issues, CFD applications, and in related experimentation and validation highlighted during the CRP.

This publication has been produced as part of the IAEA's Modelling and Data for Radiological Impact Assessments (MODARIA) programme. It summarizes the activities of Working Group 7, which was one of ten working groups within MODARIA, and focused on the harmonization and intercomparison of models for the accidental release of tritium to the atmosphere. It addresses the modelling of tritium into the atmosphere and the subsequent terrestrial processes that determine the dynamic transfer of tritium in the environment. The first half of the report contains a literature review regarding state-of-the-art modelling of tritium in the terrestrial environment. The second half summarizes the results of an intercomparison exercise undertaken using four models to inform the direction of future research.

The response of a nuclear installation's structure during an earthquake depends on the characteristics of the ground motion, the surrounding soil and the structure itself. Soil– structure interaction (SSI) analysis is used to evaluate the effects of seismic ground motion on an installation's structure, system and components, to ensure it is designed to withstand the effects of earthquakes, without loss of safety functions. This publication presents SSI phenomena and current practices in SSI modelling, simulation methodology and analysis methods for the design and assessment of nuclear installations. It complements IAEA Safety Standards Series No. SSG-67, Seismic Design for Nuclear Installations, and No. NS-G-2.13, Evaluation of Seismic Safety for Existing Nuclear Installations.

A number of IAEA Member States generate relatively small quantities of radioactive waste and/or disused sealed sources in research or in the application of nuclear techniques in medicine and industry. This publication presents a modular approach to the design of waste processing and storage facilities to address the needs of such Member States with a cost effective and flexible solution that allows easy adjustment to changing needs in terms of capacity and variety of waste streams. The key feature of the publication is the provision of practical guidance to enable the users to determine their waste processing and storage requirements, specify those requirements to allow the procurement of the appropriate processing and storage modules and install and eventually operate those modules.

This Safety Guide provides recommendations on how to meet the applicable safety requirements in relation to the design aspects of new nuclear installations subjected to seismic hazard.

New recommendations include applications of seismic isolation systems, the seismic margin to be achieved by the design and application of the graded approach. This Safety Guide is intended for use by organizations involved in the seismic design of nuclear installations, in analysis, verification and review, and in the provision of technical support, as well as by regulatory bodies.

The history of mankind is a story of ascent to unprecedented levels of comfort, productivity and consumption, enabled by the increased mastery of the basic reserves and flows of energy. This miraculous trajectory is confronted by the consensus that anthropogenic emissions are harmful and must decrease, requiring de-carbonization of the energy system. The mature field of indicator-based sustainability assessment provides a rigorous systematic framework to balance the pros and cons of the various existing energy technologies using lifecycle assessments and weighting criteria covering the environment, economy, and society, as the three pillars of sustainability. In such a framework, nuclear power is ranked favorably, but since emphasis is often placed on radioactive wastes and risk aversion, renewables are usually ranked top. However, quantifying the severity of the consequences of nuclear accidents on a rough integral cost basis and balancing severity with low core-damage accident probabilities indicates that the average external cost of such accidents is similar to that of modern renewables, and far less than carbon-based energy. This book formulates the overall goal and associated unprecedented demanding criteria of taming nuclear risks by excluding mechanisms that lead to serious accidents and avoiding extremely long stewardship times as far as possible, by design. It reviews the key design features of nuclear power generation, paving the way for the exploration of radically new combinations of technologies to come up with "revolutionary" or even "exotic" system designs. The book also provides scores for the selected designs and discusses the high potential for far-reaching improvements, with small modular lines of the best versions as being most attractive. Given the ambition and challenges, the authors call for an urgent increase in funding of at least two orders of magnitude for a broad international civilian "super-Apollo" program on nuclear energy systems. Experience indicates that such investments in fundamental technologies enable otherwise unattainable revolutionary innovations with massive beneficial spillovers to the private sector and the public for the next generations.

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.
