Decommissioning activities are clearly set to increase internationally, giving rise to a sizeable market, growing in business and competition. Meanwhile, ongoing decommissioning work continue at a sustained rate in the numerous legacy sites. It is thus clear that the challenges faced by the industry in relation to decommissioning are significant, spanning technical, political, financial, social and environmental issues, and raising questions over the adequacy of the necessary expertise and infrastructure, as well as the ability to finance the costs. One factor that adds complexity is the state of knowledge on decommissioning costs, with cost estimations showing significant differences from one country to another, even between facilities of the same type.
Therefore, the Committee for Technical and Economic Studies on Nuclear Energy Development and Fuel Cycle (NDC) decided to include in its programme of work for 2013-2014 a study on the costs of decommissioning, to be developed by the Expert Group on Costs of Decommissioning (COSTSDEC). The work is conducted in collaboration with the Radioactive Waste Management Committee (RWMC) as well as the International Atomic Energy Agency (IAEA) and the European Commission (EC), both represented in the Expert Group.
Objectives and scope
- Gather and assess the available knowledge on completed decommissioning projects from different countries and, to the extent possible, consider how related cost estimates have varied over time; how uncertainties were taken into account and what contingencies were built into the planning; and what have been the key factors impacting costs.
- Review economic methodologies and related aspects for the management of NPP decommissioning in OECD countries and, if possible, in selected other countries, including the funding mechanisms in place or under consideration, how the funds are managed and the extent to which they have increased. This assessment build upon and complement the work undertaken by the EU DFG.
- Consideration is given to including, to the extent possible, costs estimates for high level processes and their cost ranges.
