Nuclear Decommissioning


Book Description

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

Handbook of Nuclear Engineering


Book Description

This is an authoritative compilation of information regarding methods and data used in all phases of nuclear engineering. Addressing nuclear engineers and scientists at all levels, this book provides a condensed reference on nuclear engineering since 1958.




Disarmament and Decommissioning in the Nuclear Domain


Book Description

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.

Concrete in the Service of Mankind


Book Description

Concrete is ubiquitous and unique, found in every developed and developing country. Indeed, there are no alternatives to concrete as a volume construction material for infrastructure. This raises important questions of how concrete should be designed and constructed for cost effective use in the the short and long term, and to encourage further radical development. Equally, it must be environmentally friendly during manufacture, in an aesthetic presentation in structures and in the containment of harmful materials.; The central theme of the Congress is Concrete in the Service of Mankind, under which five self-contained Conferences, each dealing with a particular aspect, are planned. The Congress offers opportunity to discuss how to improve and extend this service to mankind using responsible exploitation, underwritten by sound technical understanding and research base. It brings together the shared skills and experience of the various disciplines involved in the construction process world wide.; This major publication continues the tradition established by Dundee University of organizing major international conferences every three years dealing with some aspect of concrete and also the link between Spon and Dundee University for publication of the proceedings.; This book should be of interest to concrete technologists; contractors; civil engineers; consultants; government agencies; research organizations.




Radiological Characterization of Shut Down Nuclear Reactors for Decommissioning Purposes


Book Description

This report describes and assesses radiological characterization as a precursor to decommissioning. It shows the influence of the radioactive inventory on the planning and strategies of decommissioning and also presents an extensive overview of characterization results on various reactors which have been or are being decommissioned.




Decommissioned Russian Nuclear Submarines and International Cooperation


Book Description

With the end of the Cold War, Russia's submarines were no longer needed to deter or fight Western navies and were very expensive to operate and maintain. Older submarines were taken out of service in large numbers, but without firm plans and infrastructure in place to remove and adequately care for their nuclear components, problems soon developed over the disposition of spent fuel assemblies. Problems arose also of course between Russia and the international community as to the best way to respond to the challenge. This book looks at those problems, first discussing Russia's economy, its environment, and the Russian Navy, and then covering in detail the spent fuel of Russian submarines and related nuclear problems. The engagement of the international community on the issue is then addressed. A theoretical analysis is offered on how Russia's fellow nations can help remedy a troubling environmental problem in a difficult country.
