Fractional-Order Models for Nuclear Reactor Analysis presents fractional modeling issues in the context of anomalous diffusion processes in an accessible and practical way. The book emphasizes the importance of non-Fickian diffusion in heterogeneous systems as the core of the nuclear reactor, as well as different variations of diffusion processes in nuclear reactors which are presented to establish the importance of nuclear and thermohydraulic phenomena and the physical side effects of feedback. In addition, the book analyzes core issues in fractional modeling in nuclear reactors surrounding phenomenological description and important analytical sub-diffusive processes in the transport neutron. Users will find the most innovative modeling techniques of nuclear reactors using operator differentials of fractional order and applications in nuclear design and reactor dynamics. Proposed methods are tested with Boltzmann equations and non-linear order models alongside real data from nuclear power plants, making this a valuable resource for nuclear professionals, researchers and graduate students, as well as those working in nuclear research centers with expertise in mathematical modeling, physics and control.

The Microbiology of Nuclear Waste Disposal is a state-of-the-art reference featuring contributions focusing on the impact of microbes on the safe long-term disposal of nuclear waste. This book is the first to cover this important emerging topic, and is written for a wide audience encompassing regulators, implementers, academics, and other stakeholders. The book is also of interest to those working on the wider exploitation of the subsurface, such as bioremediation, carbon capture and storage, geothermal energy, and water quality. Planning for suitable facilities in the U.S., Europe, and Asia has been based mainly on knowledge from the geological and physical sciences. However, recent studies have shown that microbial life can proliferate in the inhospitable environments associated with radioactive waste disposal, and can control the long-term fate of nuclear materials. This can have beneficial and damaging impacts, which need to be quantified.

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.

After Atomic Junction, along the Haatso-Atomic Road there lies the Ghana Atomic Energy Commission, home to Africa's first nuclear programme after independence. Travelling along this road, Abena Dove Osseo-Asare gathers together stories of conflict and compromise on an African nuclear frontier. She speaks with a generation of African scientists who became captivated with 'the atom' and studied in the Soviet Union to make nuclear physics their own. On Pluton Lane and Gamma Avenue, these scientists displaced quiet farming villages in their bid to establish a scientific metropolis, creating an epicentre for Ghana's nuclear physics community. By placing interviews with town leaders, physicists and local entrepreneurs alongside archival records, Osseo-Asare explores the impact of scientific pursuit on areas surrounding the reactor, focusing on how residents came to interpret activities on these 'Atomic Lands'. This combination of historical research, personal and ethnographic observations shows how Ghanaians now stand at a crossroad, where some push to install more reactors, whilst others merely seek pipe-borne water.

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
