Cross Country Survey On The Decommissioning Of Commercial Nuclear Reactors

In this survey paper, we bring together the insights from six country case studies on decommissioning commercial nuclear power plants (NPPs). Nuclear decommissioning has often been overlooked in past literature but will gain relevance in future research as more and more NPPs reach the ends of their respective lifetimes. The six countries we selected for our research have commercial nuclear industries that span a wide spectrum in terms of organization, regulation, financial provisions, and production of decommissioning services. Based on the cross comparison of countries and their approaches to decommissioning, we highlight a series of gaps in the existing research that we and other researchers should fill in order to derive best practices for the commercial decommissioning industry.

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.

While refurbishments for the long-term operation of nuclear power plants and for the lifetime extension of such plants have been widely pursued in recent years, the number of plants to be decommissioned is nonetheless expected to increase in future, particularly in the United States and Europe. It is thus important to understand the costs of decommissioning so as to develop coherent and cost-effective strategies, realistic cost estimates based on decommissioning plans from the outset of operations and mechanisms to ensure that future decommissioning expenses can be adequately covered. This study presents the results of an NEA review of the costs of decommissioning nuclear power plants and of overall funding practices adopted across NEA member countries. The study is based on the results of this NEA questionnaire, on actual decommissioning costs or estimates, and on plans for the establishment and management of decommissioning funds. Case studies are included to provide insight into decommissioning practices in a number of countries.

Cost estimation for the decommissioning of nuclear facilities can vary considerably in format, content and practice both within and across countries. These differences may have legitimate reasons but make the process of reviewing estimates complicated and the estimates themselves difficult to defend. Hence, the joint initiative of the OECD Nuclear Energy Agency (NEA), the International Atomic Energy Agency (IAEA) and the European Commission (EC) was undertaken to propose a standard itemisation of decommissioning costs either directly for the production of cost estimates or for mapping estimates onto a standard, common structure for purposes of comparison. This report updates the earlier itemisation published in 1999 and takes into account experience accumulated thus far. The revised cost itemisation structure has sought to ensure that all costs within the planned scope of a decommissioning project may be reflected. The report also provides general guidance on developing a decommissioning cost estimate, including detailed advice on using the structure.

This open access book discusses the eroding economics of nuclear power for electricity generation as well as technical, legal, and political acceptance issues. The use of nuclear power for electricity generation is still a heavily disputed issue. Aside from technical risks, safety issues, and the unsolved problem of nuclear waste disposal, the economic performance is currently a major barrier. In recent years, the costs have skyrocketed especially in the European countries and North America. At the same time, the costs of alternatives such as photovoltaics and wind power have significantly decreased.

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.

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.

This is the first report published by the IAEA which provides guidance on the preparation and implementation of the decommissioning of different types of research reactor. Different construction and operational features of research reactors have a major impact on the decommissioning techniques required. This report offers information on the conclusions drawn from a number of completed projects and identifies their similarities and differences. It is complemented by a computerized research reactor databank. Staff requirements, decommissioning costs waste activity are presented graphically according to reactor thermal power and integrated energy.

The May 2007 White Paper "Meeting the energy challenge: a white paper on energy" (Cm. 7124, ISBN 9780101712422) set out the Government's international and domestic strategy to address the two main challenges: tackling climate change by reducing carbon dioxide emissions; and ensuring clean and affordable energy as the country becomes increasingly dependent on imported fuel. An online consultation on nuclear power and the role of the private sector: www.direct.gov.uk/nuclearpower2007 was produced at the same time. This White Paper sets out the Government's decision taken in response to the consultation. The Government believes it is in the public interest that new nuclear power stations should have a role to play in the country's future energy mix alongside other low-carbon sources; that energy companies should have the option of investing in them; and that the Government should take active steps to open up the way to the construction of new nuclear power stations. It will be for the energy companies to fund, develop and build the new stations, including meeting the full costs of decommissioning and their full share of waste management costs. Section 1 summarises the consultation process. Section 2 addresses the key issues that arose from the consultation and how they have been taken into account in shaping policy and reaching conclusions. Section 3 outlines the facilitative actions the Government will take to reduce the regulatory and planning risks associated with investing in new nuclear power stations. Finally there are three annexes: alternatives to nuclear power; justification and strategic siting assessment processes; regulatory and advisory structure for nuclear power.

This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.
