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.
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
On the basis of the principles included in the Fundamental Safety Principles, IAEA Safety Standards Series No. SF-1, this Safety Requirements publication establishes requirements applicable to the design of nuclear power plants. It covers the design phase and provides input for the safe operation of the power plant. It elaborates on the safety objective, safety principles and concepts that provide the basis for deriving the safety requirements that must be met for the design of a nuclear power plant. Contents: 1. Introduction; 2. Applying the safety principles and concepts; 3. Management of safety in design; 4. Principal technical requirements; 5. General plant design; 6. Design of specific plant systems.
Despite all the efforts being put into expanding renewable energy sources, large-scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear plants whose protective function means they are classified as safety-related, have to meet particular construction requirements more stringent than those involved in conventional construction. This book gives a comprehensive overview from approval aspects given by nuclear and construction law, with special attention to the interface between plant and construction engineering, to a building structure classification. All life cycle phases are considered, with the primary focus on execution. Accidental actions on structures, the safety concept and design and fastening systems are exposed to a particular treatment. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.
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
Describes the rationale and vision for the peaceful use of nuclear energy. The publication identifies the basic principles that nuclear energy systems must satisfy to fulfil their promise of meeting growing global energy demands.
