The assessment approach described in this publication provides a comprehensive means to determine the status of the infrastructure conditions relevant to all issues detailed in IAEA Nuclear Energy Series No. NP-T-5.1, Specific Considerations and Milestones for a Research Reactor Project. This approach can be used by any interested Member State for self-assessment to identify weaknesses and to determine the additional work needed to develop its national nuclear infrastructure for research reactor programme to an appropriate level. Member States planning to embark on both a research reactor programme and a nuclear power programme, may refer to this publication to ensure that the approach and methodology for the implementation of both programmes is harmonized, efficient and effective.

Flexible operation and related power changes can have a direct impact on fuel integrity through pellet–cladding interaction/stress corrosion cracking (PCI/SCC) phenomena, which could lead to fuel failures in certain conditions. For some anticipated operational occurrences that affect fuel with small PCI/SCC margins, the fuel failures caused by PCI/SCC cannot be assumed to be benign, and a significant radiological source term may be generated. This publication provides an overview of PCI/SCC studies and reports on the progress made since the early 2000s, based on presentations and discussions at a related IAEA technical meeting held in October 2019.

This publication provides an update on the current status of nuclear power and prospects for its contribution, together with other low carbon energy sources, to ambitious mitigation strategies that will help the world limit global warming to 1.5 DegreesC in line with the 2016 Paris Agreement. Since 2000, the IAEA has issued such information and analysis regularly, in order to support those Member States that choose to include nuclear power in their energy system as well as those considering other strategies. The focus of the 2020 publication is on the significant potential of nuclear energy, integrated in a low carbon energy system, to contribute to the 1.5 DegreesC climate change mitigation target, and the challenges of realizing this potential. Energy system and market related factors affecting the transition to a low carbon energy system are reviewed. This edition also outlines developments needed to realize the large scale capacity increase required to rapidly decarbonize the global energy system in line with limiting global warming to 1.5 DegreesC.

Experience shows that an assessment of the seismic capacity of an existing operating facility can be required for a number of reasons, for example identification of potential seismic vulnerabilities based on operating experience events or the periodic safety review programme. This publication covers the seismic safety evaluation programmes to be performed on existing nuclear installations in order to ensure that the required fundamental safety functions are available, with particular application to the safe shutdown of reactors. It includes lessons learned based on the IAEA Action Plan for Strengthening Nuclear Safety, following the Fukushima accident, and updated methodologies for seismic safety evaluation of nuclear installations.

This publication presents the proceedings of the IAEA International Conference on the Management of Spent Fuel from Nuclear Power Reactors, held in 2019, with the theme ‘Learning from the Past, Enabling the Future’. The purpose of the event was to provide a forum for the exchange of information on national spent fuel management strategies and on the ways in which a changing energy mix could influence these strategies and on how they support the achievement of national energy goals. The broad scope of the conference covered all stages of the management of spent fuel from the past, present and future technologies, and how it can be affected by the decisions taken in the rest of the nuclear fuel cycle. The event brought together experts from countries with decades of nuclear power operating experience and those from countries currently developing or considering a nuclear power programme. The importance of sharing data, operational experience, lessons learned and international collaboration in research and development (R&D) activities, and how its development and implementation can lead to attainable solutions was highlighted. Special attention was given to the young generation of professionals to support bridging the gap with the current ageing industry workforce.

This publication provides a set of systematic descriptive models for each uranium deposit type, subtype and class, using a consistent approach to summarise the same types of information for each. Each model is intended to have a standalone capability, using a tabular style that is typical of conventional mineral resource industry standards. Each deposit model includes a map showing the distribution of deposits, and grade-tonnage graphs. Collectively, these databases and models form a basis for assessing the global distribution of uranium deposits and evaluating supply-demand scenarios. With these, the IAEA can provide the capability for Member States to assess the potential of remaining - or speculative - uranium resources for long term supply beyond identified resources in a consistent and reproducible manner.

For reactors currently operating, the types of wastes expected to be generated under normal operating regime are known and, aside from a few problematic wastes (such as graphite, tritium and radiocarbon) most of these wastes have clearly defined cradle-to-grave (end-to-end) pathways. However, for advanced and innovative reactors and their fuel cycles, some waste types may either have new or different properties or might be problematic for processing with the currently available technologies. One of the primary challenges for advanced and innovative reactors and their nuclear fuel cycles is that solutions must be identified for all eventually problematic wastes prior to initiating construction of these facilities. This publication sets the stage for considering the waste generation of advanced fuel fabrication, reactor operation and decommissioning, reprocessing of spent fuel and waste pathways early in the development of new reactors and their associated fuel cycles. It describes waste flows in broad chemical and physical terms and identifies possible processing, recycling and disposition pathways. The publication is intended to support the nuclear industry in taking an early and integrated approach to waste managemen

Advanced separations technology is key to closing the nuclear fuel cycle and relieving future generations from the burden of radioactive waste produced by the nuclear power industry. Nuclear fuel reprocessing techniques not only allow for recycling of useful fuel components for further power generation, but by also separating out the actinides, lanthanides and other fission products produced by the nuclear reaction, the residual radioactive waste can be minimised. Indeed, the future of the industry relies on the advancement of separation and transmutation technology to ensure environmental protection, criticality-safety and non-proliferation (i.e., security) of radioactive materials by reducing their long-term radiological hazard. Advanced separation techniques for nuclear fuel reprocessing and radioactive waste treatment provides a comprehensive and timely reference on nuclear fuel reprocessing and radioactive waste treatment. Part one covers the fundamental chemistry, engineering and safety of radioactive materials separations processes in the nuclear fuel cycle, including coverage of advanced aqueous separations engineering, as well as on-line monitoring for process control and safeguards technology. Part two critically reviews the development and application of separation and extraction processes for nuclear fuel reprocessing and radioactive waste treatment. The section includes discussions of advanced PUREX processes, the UREX+ concept, fission product separations, and combined systems for simultaneous radionuclide extraction. Part three details emerging and innovative treatment techniques, initially reviewing pyrochemical processes and engineering, highly selective compounds for solvent extraction, and developments in partitioning and transmutation processes that aim to close the nuclear fuel cycle. The book concludes with other advanced techniques such as solid phase extraction, supercritical fluid and ionic liquid extraction, and biological treatment processes. With its distinguished international team of contributors, Advanced separation techniques for nuclear fuel reprocessing and radioactive waste treatment is a standard reference for all nuclear waste management and nuclear safety professionals, radiochemists, academics and researchers in this field.

Computer security is increasingly recognized as a key component in nuclear security. As technology advances, it is anticipated that computer and computing systems will be used to an even greater degree in all aspects of plant operations including safety and security systems. A rigorous and comprehensive assessment process can assist in strengthening the effectiveness of the computer security programme. This publication outlines a methodology for conducting computer security assessments at nuclear facilities. The methodology can likewise be easily adapted to provide assessments at facilities with other radioactive materials.

The Fukushima nuclear power plant explosions and the Hiroshima/Nagasaki bombings are intimately connected events, bound together across time by a nuclear will to power that holds little regard for life. In Fukushima: Dispossession or Denuclearization? contributors document and explore diverse dispossession effects stemming from this nuclear will to power, including market distortions, radiation damage to personal property, wrecked livelihoods, and transgenerational mutations potentially eroding human health and happiness. Liberal democratic capitalism is itself disclosed as vulnerable to the corrupting influences of the nuclear will to power. Contributors contend that denuclearization stands as the only viable path forward capable of freeing humans from the catastrophic risks engineered into global nuclear networks. They conclude that the choice of dispossession or denuclearization through the pursuit of alternative technologies will determine human survival across the twenty-first century.

An examination of how the technical choices, social hierarchies, economic structures, and political dynamics shaped the Soviet nuclear industry leading up to Chernobyl. The Chernobyl disaster has been variously ascribed to human error, reactor design flaws, and industry mismanagement. Six former Chernobyl employees were convicted of criminal negligence; they defended themselves by pointing to reactor design issues. Other observers blamed the Soviet style of ideologically driven economic and industrial management. In Producing Power, Sonja Schmid draws on interviews with veterans of the Soviet nuclear industry and extensive research in Russian archives as she examines these alternate accounts. Rather than pursue one "definitive" explanation, she investigates how each of these narratives makes sense in its own way and demonstrates that each implies adherence to a particular set of ideas-about high-risk technologies, human-machine interactions, organizational methods for ensuring safety and productivity, and even about the legitimacy of the Soviet state. She also shows how these attitudes shaped, and were shaped by, the Soviet nuclear industry from its very beginnings. Schmid explains that Soviet experts established nuclear power as a driving force of social, not just technical, progress. She examines the Soviet nuclear industry's dual origins in weapons and electrification programs, and she traces the emergence of nuclear power experts as a professional community. Schmid also fundamentally reassesses the design choices for nuclear power reactors in the shadow of the Cold War's arms race. Schmid's account helps us understand how and why a complex sociotechnical system broke down. Chernobyl, while unique and specific to the Soviet experience, can also provide valuable lessons for contemporary nuclear projects.

The earthquake and resulting tsunami that severely damaged Japan's Fukushima Daiichi nuclear power plant on March 11, 2011, raised questions in Congress about the accident's possible implications for nuclear safety regulation, U.S. nuclear energy expansion, and radioactive waste policy. This book explores the current nuclear energy issues facing Congress which include federal incentives for new commercial reactors, power plant safety and regulation, radioactive waste management policy, research and development priorities, nuclear weapons proliferation, and security against terrorist attacks.

The seismic design criteria applied to sitting commercial nuclear power plants operating in the U.S. received increased attention following the March 11th, 2011 earthquake and tsunami that devastated Japan's Fukushima Daiichi nuclear power station. Since the events, some in Congress have begun to question whether U.S. plants are vulnerable to a similar threat, particularly in light of the Nuclear Regulatory Commissions's (NRC)ongoing reassessment of seismic risks at certain plant sites. This book presents some of the general design concepts of operating nuclear power plants in order to discuss design considerations for seismic events.

While it does not forego the seriousness associated with the topic, this book provides for an easy read that informs the reader of a variety of issues associated with the subject. Divided into short chapters, aspects such as technology, resource availability, economics, geopolitics and policies associated with nuclear power are dealt with in detail, but in a way that emphasizes readability. Contentious areas such as safety, waste management and the latest trends associated with them are laid bare for the reader. The book also dwells in depth on the shrill and seldom above-board debate on nuclear power and renewables. This is an invaluable companion for all those looking to understand the nature of the nuclear industry in the new millennium and the implications of international treaties such as the Indo-US nuclear deal.

An essential reference for journalists, activists, and students, this book presents scientifically accurate and accessible overviews of twenty-four of the most important issues in the nuclear realm, including: health effects, nuclear safety and engineering, Three Mile Island and Chernobyl, nuclear medicine, food irradiation, transport of nuclear materials, spent fuel, nuclear weapons, and global warming. Each 'brief' is based on interviews with named scientists, engineers, or administrators in a nuclear specialty, and each has been reviewed by a team of independent experts. The objective is not to make a case for or against nuclear-related technologies, but rather to provide definitive background information. (The approach is based on that of ""The Reporter's Environmental Handbook"", published in 1988, which won a special award for journalism from the Sigma Delta Chi Society of professional journalists.) Other features of the book include: a glossary of hundreds of terms; an introduction to risk assessment; environmental and economic impacts, and public perceptions; an article by an experienced reporter with recommendations about how to cover nuclear issues; quick guides to the history of nuclear power in the United States, important federal legislation and regulations, nuclear position statements, and key organizations; and, references for print and electronic resources.
