Recent decades have seen a significant increase in the number of decommissioning projects undertaken globally. Decommissioning technologies have advanced, driven by innovations in digitization and robotics, and the Systematic Approach to Training (SAT) methodology is now being applied to the decommissioning phase of all types of nuclear facilities. This publication provides practical information and examples of good practices in training personnel for decommissioning activities, based on Member States' experience, including guidance on the application of SAT methodology. The increasing use of digital and web?based tools to enhance competence development for implementation of decommissioning programmes is also discussed.

The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) established by the General Assembly in 1955 assesses the levels and effects of exposure to ionizing radiation on human health and the environment. This is the third of four volumes of scientific annexes provide the supporting scientific deliberations for the UNSCEAR 2020/2021 report to the General Assembly. Annex C "Biological mechanisms relevant for the inference of cancer risks from low dose and low-dose rate radiation" synthesizes the current knowledge on biological mechanisms of radiation actions at low doses and low-dose-rates, and assesses the implications for understanding the processes of cancer development after exposure to ionizing radiation, and for dose-response relationships of radiation-induced cancers.

Radiological environmental impact assessment models are important tools for public and environmental protection, for example, in planning measures to be taken in the event of accidental releases. This publication was developed to report on results from international model validation exercises conducted within the IAEA's MODARIA I programme to test and improve the modelling for predictions used for environmental transfer and dose assessment in urban areas. Model exercises were focused on: contamination densities and activity concentrations in air following short range atmospheric dispersion and deposition events; prediction of atmospheric dispersion and application of decision support systems under complex meteorological and topographic conditions; and expected reductions in ambient dose rates and activity concentrations due to protective actions following a nuclear accident. The report builds on past IAEA publications and provides relevant examples for use in strengthening the global nuclear safety framework as part of emergency preparedness and response planning following a nuclear or radiological emergency.

Each year billions of dollars are being spent in the area of nuclear power generation to design, construct, manufacture, operate, and maintain various types of systems around the globe. Many times these systems fail due to safety, reliability, human factors, and human error related problems. The main objective of this book is to combine nuclear power plant safety, reliability, human factors, and human error into a single volume for those individuals that work closely during the nuclear power plant design phase, as well as other phases, thus eliminating the need to consult many different and diverse sources in obtaining the desired information.

This Safety Guide provides recommendations and guidance on achieving and demonstrating compliance with IAEA Safety Standards Series No. SSR-6 (Rev. 1), Regulations for the Safe Transport of Radioactive Material (2018 Edition), which establishes the requirements to be applied to the national and international transport of radioactive material. Transport is deemed to comprise all operations and conditions associated with and involved in the movement of radioactive material, including the design, fabrication and maintenance of packaging, and the preparation, consigning, handling, carriage, storage in transit, shipment after storage and receipt at the final destination of packages. The Advisory Material is not a stand-alone text. It is to be used concurrently as a companion to the IAEA Safety Standards Series No. SSR-6 (Rev. 1) and each paragraph of this guide is numbered correspondingly to the paragraph of the Regulations to which it most directly relates.

Communication and stakeholder involvement are essential components for a successful disposal programme. Experience around the world suggests that the scientific and technological bases for the safe disposal of radioactive waste are available — disposal solutions exist or can be developed based on established knowledge. However, concerns and opposition among the public and other stakeholders could slow or even prevent the implementation of needed disposal solutions. This publication provides practical guidance on communication and stakeholder involvement for countries embarking on, relaunching or revising a disposal programme. It draws upon past experiences and emphasizes that practical implementation requires adjusting to the evolving context as given by the national, social and political circumstances. The primary intended users of this publication include those working in the field of radioactive waste management in government, regulatory bodies and industry, an especially in organizations responsible to implement solutions for radioactive waste disposal.

This publication provides a global overview of the status of spent fuel and radioactive waste management programmes, inventories, current practices, technologies and trends. It presents information on national arrangements for the management of spent fuel and radioactive waste, and on current waste and spent fuel inventories and their future estimates. Achievements, challenges and trends in the management of spent fuel and radioactive waste are also addressed. This second edition has been developed with a basis of national profiles submitted by Member States, complemented with openly available Joint Convention National Reports. The data reported are fully dependent on the input from the States and by the assumptions made to transform these data into the waste classes defined in IAEA Safety Standards Series No. GSG?1, Classification of Radioactive Waste.

The focus of this publication is on collecting current practices in Member States related to design extension conditions (DECs) with core melting. The information provided is based on the feedback from technical experts from Canada, France, Finland, India, the Islamic Republic of Iran, the Russian Federation, and the United States of America. There is, however, still no common understanding of DECs due to the complexity of phenomena and insufficient experimental data. This publication identifies current approaches of IAEA Member States with active nuclear power programmes and discusses the regulatory perspective and technical rationale. It attempts to find common practices and possible areas for harmonization of the main rules related to the analysis of DECs with core melting for new water cooled reactors, including their selection for the safety demonstration.

Cyclotrons are currently used for the preparation of a wide variety of radionuclides that have applications in single photon emission computed tomography (SPECT) and positron emission tomography (PET). Consequently, there is high demand from IAEA Member States for support in the area of radiopharmaceutical production using cyclotron produced radioisotopes. This publication describes the potential radionuclide production routes using cyclotrons in different energy ranges and provides methods for the development of targets and provides details of the chemistry for the separation of radionuclides from target materials. The readership of this publication includes scientists, operators interested in putting this technology into practice, technologists already working with cyclotrons who wish to enhance the utility of existing machines, and managers in the process of setting up radionuclide facilities in their countries. Students working towards higher level degrees in related fields may also benefit from this publication.

This publication provides detailed guidance on developing, implementing, and integrating computer security as a key component of nuclear security. This guidance applies to computer security aspects of nuclear security and its interfaces with nuclear safety and with other elements of a State's nuclear security regime, including the security of nuclear material and nuclear facilities, of radioactive material and associated facilities, and of nuclear and other radioactive material outside of regulatory control. The scope of this publication includes: computer?based systems, the compromise of which could adversely affect nuclear security or nuclear safety; the State's and relevant entities roles and responsibilities in relation to computer security in the nuclear security regime; the activities of the State in establishing and implementing a computer security strategy for nuclear security; the elements and measures for subordinate computer security programmes; and the activities to sustain the strategy.

The story of the rise, fall and second ascendancy of nuclear power in the United Kingdom. Britain was a pioneer in civil nuclear power and there were once high hopes in the 1950s that this could be a source of cheap electricity and a valuable export opportunity. In The Fall and Rise of Nuclear Power in Britain, Simon Taylor examines why these hopes were never realised, and how we have come to see a new rise in nuclear power in recent years. He traces the UK’s nuclear energy history, from the optimism of the 1950s, through the disillusionment of the 1980s, to a new role for nuclear in the 21st century. The construction of Britain’s first new nuclear power station in 20 years, Hinkley Point C, marks a major change of policy. Throughout this book, Taylor provides a comprehensive overview of energy policy, economics, politics and changing environmental priorities, keying into debates about the generation and sustainability of this controversial energy source. Will this new nuclear energy turn out to be a heroic story of UK leadership on a matter of global importance, or will it prove a hugely costly folly, as with British nuclear power in the past?

This publication presents detailed concepts and procedures for the preparation, conduct and evaluation of exercises to test relevant nuclear security systems and measures, and provides useful templates and checklists that can be used to assist the exercise development process. The technical guidance provided is targeted at States and their competent authorities to assist them in establishing and sustaining an effective infrastructure to strengthen detection of and response to material out of regulatory control and evaluate the effectiveness of their plans by presenting a structured methodology for the consistent development of exercises.

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.

This new revision provides guidance to States and their competent authorities on how to establish or improve, implement, maintain and sustain the elements of the nuclear security regime related to radioactive material, associated facilities and activities, with particular emphasis on the development of regulatory requirements. The publication applies to the security of radioactive material in use or in storage as well as associated facilities and associated activities and assists Member States in their regimes against unauthorized removal of the radioactive material or sabotage performed with the intent to cause harmful radiological consequences.

On 14 April 1912, less than a week into a transatlantic trip from Southampton to New York, the largest luxury cruise liner in the world struck an iceberg off the coast of Labrador, causing the hull to buckle. The massive 50,000 ton ship hailed as 'unsinkable' was soon slipping into the cold Atlantic Ocean, the crew and passengers scrambling to launch lifeboats before being sucked into the deep. Of the 2,224 passengers and crew aboard, more than 1,500 died, making the sinking one of the deadliest for a single ship up to that time. The sinking has captured the public imagination ever since, in part because of the scale of the tragedy, but also because the ship represented in microcosm Edwardian society, with the super-rich sharing the vessel with poor migrants seeking a new life in North America. Other factors, such as why there were only enough lifeboats to hold half the passengers, also caused controversy and led to changes in maritime safety. In later years many survivors told their stories to the press, and Titanic celebrates these accounts. A final chapter examines the shipwreck today, which has been visited underwater by explorers, scientists and film-makers, and many artifacts recovered as the old liner steadily disintegrates. Titanic offers a compact, insightful photographic history of the sinking and its aftermath in 180 authentic photographs.

The nuclear industry is in a state of flux. Proclamations of a nuclear renaissance have given way to predictions of the industry's ultimate decline, and now, in the face of new carbon emissions regulation, renewed optimism for the future. Yet, nuclear plants are currently at-risk due to electricity market design issues and competition with low priced natural gas. This book attempts to provide clarity to the potential outlook for the nuclear industry by examining the factors that influence it. It includes an analysis of recent trends affecting nuclear power generation while focusing on the specific potential impact of the EPA's proposed Clean Power Program on nuclear power.

Civil engineering has an important part to play at every stage of the nuclear fuel cycle - from the choice of site and conception of the design of a major power station or fuel plan through modifications during operations, to the final stages of designing and building waste management stores and repositories. Technical demands on designers and builders of nuclear plants are ever increasing and together with ever greater safety requirements the designer has to consider natural and man-made disasters. Inevitably increased safety and quality standards result in increased costs. This book examines ways in which the industry has responded to this challenge with new methods of construction giving higher productivity and faster construction times.

This book is a unique introduction to the economic costs of nuclear power. It examines the future of the nuclear power industry and unpacks the complicated relationships between its technical, economic and political variables. It does so by modelling the costs, risks and uncertainties of one of the world's most opaque industries using micro-econometrics, econometrics, and cost engineering. Economics of Nuclear Power examines the very important costs of externalities (storing of nuclear waste and the impact of a Chernobyl or Fukushima event) and compares those to the externalities of alternative carbon based energies (oil, coal, natural gas). With over 100 tables and figures this book details nuclear power production around the world - present and planned, providing a completely global focus. It also includes an overview of the past 70 years of international nuclear power developments. This book is essential reading for students, scholars and professionals interested in energy economics, nuclear engineering and energy policy.

The magnitude 9.0 Great East Japan Earthquake occurred on March 11, 2011, claiming over 20,000 lives. It crippled the Fukushima Daiichi Nuclear Power Plant, whose hydrogen-air explosions contaminated wide areas around Fukushima with radionuclides. The number of evacuees initially totaled 328,903, but has been reduced to 263,392 as of February 13, 2014. More than half of the evacuees (132,500) consist of Fukushima residents, and 67% of whom have experienced mental or physical disorders. Indeed, refugee life is so difficult that many Fukushima families have been affected by suicide, divorce, separation of family members, migration and settlement to other places, mental illness, etc. The difficulty is caused by the fear of low-dose radiation induced by the LNT model which claims that radiation cancer risk is linearly proportional to dose without any threshold. Careful scrutiny of the model, however, clearly indicates that the linearity is invalid; low dose radiation is not hazardous, but is even beneficial or hormetic because of the adaptive response to radiation. This book provides ample evidence to negate the LNT model. This book is primarily compiled to get rid of the spell of the LNT model and release Fukushima people from undue torture. The book would also be useful to the public in general who have CT scans and have concerns. In addition, the people who use radiation world-wide such as nuclear power plant workers, radiation researchers, radiologists, and X-ray operators would be relieved to learn from reading this book that the alleged risk of low-dose radiation is illusionary and that the low-dose radiation is even beneficial. Policy makers of nuclear energy and radiation who are working for governmental and/or regulatory agencies are also recommended to read this book. Severe guidelines from a safety standpoint sometimes entrap people into a fear-stricken situation rather than save them, as no one was killed by radiation directly, but more than 1,000 people have been killed by the fear of radiation secondarily in Fukushima. By the same token, this book is recommended to civil activists and journalists who emphasise dangers of low-dose radiation and raise fear of low-dose radiation. It is the time to shed new scientific light on the outdated LNT model.

The near meltdown in 1979 at Three Mile Island, America, plunged the nuclear power industry into a crisis of confidence that threatened its very existence. This work analyzes how the industry managed to stabilize itself through a complete transformation in the safety standards, operation and management of nuclear facilities in America. After describing the poor quality of safety before disaster shook the industry into action, the book documents the emergence of the Institute of Nuclear Power Operations (INPO) and reveals how this industry organization became a major force behind improvements in nuclear safety. In his account of INPO's beginnings and its functions, the author shows how, contrary to conventional wisdom, industry self-regulation can be remarkably effective. For Rees, what happened for the nuclear power industry suggests a new form of regulation - communitarian regulation - that has important implications for the role of private and public control of other key industries.

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.

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.

Gamma irradiation of food is a simple, reliable, and mature technology. However, more use of alternative irradiation technologies, based on electrically generated sources, would help complement the available capacity. Electron beams and X rays generated from electricity are technologies that avoid the procurement, transport, storage, disposal, and safeguarding issues associated with the use of radioisotopes. Arising from an IAEA coordinated research project, this publication reports on research to develop new tools in food irradiation and to rapidly ascertain treatment parameters before irradiation, including high energy (MeV) and low energy (keV) electron beam and X ray irradiation. Comparative studies of gamma, electron beam and X ray irradiation for food and phytosanitary uses are also presented.
