The Expert Group on Costing for Decommissioning of Nuclear Installations and Legacy Management (EGCDL) was established in June 2020 to address costing issues for decommissioning of nuclear installations and legacy management as a level three CDLM expert group.

The EGCDL main objectives are to foster the exchange of information and experiences; to describe good practices in decommissioning and legacy management cost estimation; and to consider risks associated with financial consequences in cost estimation and financing. The EGCDL also advises the CDLM on major and emerging issues in the area of cost estimation. 

The Global Tasks, or larger themes of work, presently being addressed by the Expert Group are identified below. 

Global Task 1. Integrating the International Structure for Decommissioning Costing (ISDC) and addressing uncertainties in cost estimates for decommissioning nuclear facilities. Particular focus on collecting available guidance into a new report to make it more readily applicable to complex and legacy sites beyond current NPP facilities.

Global Task 2. Applying the ISDC and uncertainties guidance towards complex and legacy sites and identifying any possible gaps that exist in the current ISDC structure at Level 2 (activity groups) and Level 3 (cost activities) that is needed for cost estimation of decommissioning of complex/legacy sites; and developing a description of identified gaps at Level 2 and Level 3 activities, potentially illustrated with case studies.

Global Task 3. Providing technical guidance on applying benchmarking for costing in the context of decommissioning and legacy management. 

To develop cost benchmarking guidance, non-ISDC format work breakdown structures will be translated into ISDC Level 1 format, capturing data conversion assumptions/boundaries and rationale for decision-making during the transition process.  Categories containing the highest liability will also be included to inform the focus of future cost benchmarking projects.
