This publication explores the implications of decommissioning in the light of unexpected events and the trade-off between activities to reduce them and factors militating against any such extra work. It classifies and sets out some instances where unexpected findings in a decommissioning programme led to a need to either stop, or reconsider the work, re-think the options, or move forward on a different path. It provides practical guidance in planning and management of decommissioning taking into account unexpected events. This guidance includes an evaluation of the experience and lessons learned in tackling decommissioning that is often neglected. Thus it will enable future decommissioning teams to adopt the relevant lessons to reduce additional costs, time delays and radiation exposures.

As part of the Action Plan on Nuclear Safety, the IAEA led the International Project on Managing the Decommissioning and Remediation of Damaged Nuclear Facilities (DAROD Project). The DAROD Project focuses on providing practical guidance for the decommissioning and remediation of accident damaged nuclear facilities based on case studies of actual damaged facilities and lessons learned. This publication summarizes the outcomes of the DAROD Project. It is intended for regulatory bodies, operating organizations, technical support organizations and governmental officials who are involved in the decommissioning and remediation of nuclear facilities damaged after an accident or owing to a legacy deterioration.

Following the acquisition of the atomic bomb by five states, the United Nations began drafting several treaties to limit nuclear proliferation. These efforts failed, as four more states also acquired nuclear weapons. In a similar vein, an attempt to limit atomic weapons - primarily within the two superpowers - was initiated. While the number of weapons has decreased, the new bombs now being manufactured are more powerful and more precise, negating any reduction in numbers. In the field of civil nuclear use, all nuclear facilities (reactors, factories, etc.) have a limited lifespan. Once a plant is permanently shut down, these facilities must be decommissioned and dismantled. These operations are difficult, time-consuming and costly. In addition, decommissioning generates large volumes of radioactive waste of various categories, including long-lived and high-activity waste. Risks to the environment and to health are not negligible during decommissioning. The International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD) have produced numerous publications with recommendations. Each state has its own decommissioning strategy (immediate or delayed) and final plan for the site - whether it be returning it to greenfield status or obtaining a nuclear site license with centuries-long monitoring.

Nuclear Waste Management Facilities: Advances, Environmental Impacts, and Future Prospects examines best practices and recent trends in improving nuclear safety and reducing the negative environmental impacts of nuclear waste. With strong emphasis on regulatory requirements, this reference is essential for designing new integrated waste management practices, using lessons learned from historical and current practices. Divided into three key sections, Part One introduces the reader to the safety and environmental impacts of the nuclear industry. Part Two reviews recent technological and methodological approaches to enhancing safety, as well as reducing the carbon footprint of both individual processes and integrated facilities. Topics covered include waste processing, transmutation and decommissioning. Part Three consider potential management schemes for special waste from innovative sources, and wastes that contain emerging contaminants, including waste recycling opportunities. Nuclear Waste Management Facilities: Advances, Environmental Impacts, and Future Prospects is a crucial tool needed to implement the safest and most environmentally considerate best practices within nuclear waste management facilities. - Presents recent approaches used to assess and improve the safety and reduce the environmental impacts of nuclear waste management facilities - Offers technical guidance to support the development and defense of the environmental impact assessment (EIA) and Safety Cases to support the waste management facilities licensing throughout their lifecycles - Highlights the future perspectives for wastes produced from innovative reactors and wastes containing emerging contaminants, and recycling opportunities

The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use

Pools or ponds are usually an integrated part of a more complex nuclear facility, but in some particular cases pools may be considered as a separate nuclear facility with a specific license. A number of nuclear installations utilize pools for the cooling of spent fuel, or the shielding of research reactor cores or irradiator sources. Over a service lifetime that can span decades, nuclear pools may become contaminated as a result of the deposition of radioactive substances. Relevant aspects of pool decommissioning covered in this publication include project planning and management, health and safety, and the management of resulting waste.

"Decommissioning activities for zero-power reactors, radio-diagnostic and radiotherapy hospital departments and laboratories and factories using radioactive material may be erroneously perceived as trivial and of low priority. This publication provides practical information, experience and assistance aimed at a broad spectrum of practitioners who are faced with decommissioning of such small nuclear facilities. Particular consideration is given to the financial and scientific resources, and early planning, which are all factors essential to efficient and effective decommissioning. It is written as a simplified, stepwise approach for guidance to nuclear operators who may have little or no experience in decommissioning. An accompanying CD contains practical information in two Annexes, including descriptions of decommissioning projects problems encountered, solutions and analyses, and lessons learned"--Provided by publisher.
