Cost Estimation for Decommissioning
An International Overview of Cost Elements, Estimation Practices and Reporting Requirements
This report is based on a study carried out by the NEA Decommissioning Cost Estimation
Group (DCEG) on decommissioning cost elements, estimation practices and reporting
requirements. Its findings indicate that cost methodologies need to be updated continuously
using cost data from actual decommissioning projects and hence, systematic approaches
need to be implemented to collect these data. The study also concludes that changes
in project scope may have the greatest impact on project costs. Such changes must
therefore be identified immediately and incorporated into the estimate. Finally, the
report notes that more needs to be done to facilitate the comparison of estimates,
for example by providing a reporting template for national estimates.
