Design Lessons Drawn From The Decommissioning Of Nuclear Facilities

At a time when many older facilities are being decommissioned and many more are undergoing major retrofits to extend their lives, there is a wealth of information emerging to guide the design of new facilities. In this publication, the most important lessons learned in recent years are examined.

Once a nuclear installation has reached the end of its safe and economical operational lifetime, the need for its decommissioning arises. Different strategies can be employed for nuclear decommissioning, based on the evaluation of particular hazards and their attendant risks, as well as on the analysis of costs of clean-up and waste management. This allows for decommissioning either soon after permanent shutdown, or perhaps a long time later, the latter course allowing for radioactivity levels to drop in any activated or contaminated components. It is crucial for clear processes and best practices to be applied in decommissioning such installations and sites, particular where any significant health and environmental risks exist. This book critically reviews the nuclear decommissioning processes and technologies applicable to nuclear power plants and other civilian nuclear facilities. Part one focuses on the fundamental planning issues in starting a nuclear decommissioning process, from principles and safety regulations, to financing and project management. Part two covers the execution phase of nuclear decommissioning projects, detailing processes and technologies such as dismantling, decontamination, and radioactive waste management, as well as environmental remediation, site clearance and reuse. Finally, part three details international experience in the decommissioning of nuclear applications, including the main nuclear reactor types and nuclear fuel cycle facilities, as well as small nuclear facilities and legacy nuclear waste sites. Critically reviews nuclear decommissioning processes and technologies applicable to nuclear power plants and other civilian nuclear facilities Discusses the fundamental planning issues in starting a nuclear decommissioning process Considers the execution phase of nuclear decommissioning projects, including dismantling, decontamination, and radioactive waste management, as well as environmental remediation, site clearance and reuse

This report provides guidance on the planning for decommissioning and on the provision of relevant features at the design and construction stages of nuclear power plants. Most of the information presented is equally applicable, however, to planning and implementing the decommissioning of research reactors and prototype reactors. The report will be useful in the context of backfitting and refurbishment of existing facilities.

In recent years, several Member States have completed the decommissioning of multifacility nuclear sites. This publication consolidates their technical and organizational experience, and provides information and practical guidance that promotes safe, timely and cost effective implementation. All phases of decommissioning are discussed, from planning and dismantling to waste management and site release, as well as organizational schemes and funding. This publication is intended for decision makers, plant operators, contractors and regulators involved in planning, management, authorization and execution of decommissioning activities. It is particularly relevant for multifacility site operators with nuclear facilities approaching the end of their foreseen lifetime. The publication will also be of interest for the designers and builders of new nuclear installations in order to facilitate eventual decommissioning.

Advances and Innovations in Nuclear Decommissioning is an essential resource for industry professionals and academics interested in acquiring the most up-to-date information on the current state of nuclear decommissioning. Written and edited by the world’s leading experts, this book considers lessons learned and new innovations in the field. Edited by Dr. Laraia, it is the perfect companion to his 2012 book, Nuclear Decommissioning, which critically reviews the nuclear decommissioning processes and technologies applicable to nuclear power plants and other civilian nuclear facilities. Where the earlier book covers the basics of decommissioning, this new book brings you up-to-date with new areas of interest and approaches, innovative technologies, and lessons learned by both the nuclear and non-nuclear decommissioning sectors. Focuses on new aspects, trends and innovative technologies Includes content on decommissioning after a severe accident, including the use of robotics Brings together information from around the world and considers the lessons learned from the non-nuclear sector as well

Evaluating potential reuse/redevelopment options for nuclear facilities is an important aspect of the decommissioning process. Early planning for site reuse can facilitate the transition from operation to decommissioning and subsequently to new, profitable uses of the site. At the same time, it can reduce the financial burden associated with decommissioning and alleviate the overall impact on the local community. This publication provides an overview of completed decommissioning projects worldwide and successful ways to reuse decommissioned sites for new purposes, whereby extensive use is made of non-nuclear experience. Lessons learned from these projects and practical guidance are highlighted.

Nuclear Decommissioning Case Studies: Policies, Strategies, Planning and Knowledge Management focuses on policy, strategy, planning and knowledge management in nuclear decommissioning, offering readers guidance on events that occur in early stages of the lifecycle. The book helps readers plan in advance to avoid and reduce schedule delays and cost overruns to ensure a smooth, safe and successful decommissioning. Events covered in this book range from top-level conception, to strategy selection, the drafting of procedures, and the sharing of best practices. Alongside the other case study books in this series, readers will obtain an understanding of various key points and lessons learned. Decommissioning experts, including regulators, operators, waste managers, researchers and academics will find this book to be suitable supplementary material to Michele Laraia’s reference works on the theory and applications of nuclear decommissioning. Presents a selection of global case studies that focus on the early stages of nuclear decommissioning Highlights the need to ensure sustainability plans are in place at the beginning of a nuclear project Informs decision-makers on selecting the best options Assists the reader in setting clear plans and strategies to avoid schedule delays and cost overruns
