Working Party on Decommissioning and Dismantling (WPDD) Decommissioning Cost Estimation Group (DCEG)

The WPDD DCEG was created to foster the exchange of information and experience on issues in this field. In promoting collective learning on the subject, it aims to enhance the credibility, reliability, and auditability of the cost estimation process – thereby enhancing stakeholder confidence in the process of managing radioactive waste management liabilities. The group helps define best practices in the field of decommissioning cost estimation and to examine the scope for achieving consensus on overall objectives and developing common approaches.

The group advises the WPDD and the Radioactive Waste Management Committee (RWMC) on major and emerging issues in the area of cost estimation for decommissioning of nuclear facilities and to provide appraisals of the state of the art with a view to consolidating knowledge and disseminating it to a variety of different audiences.

The group defines, conducts and oversees studies aimed at improving the transparency and reproducibility of cost estimations, including approaches to reporting.

Where necessary, the group organises topical sessions or workshops on specific topics of interest to both the group and other bodies such as WPDD and RWMC.

Mode of operation

The group meets at least once a year. The aim of these meetings is to:

  • exchange information on recent developments in member countries;
  • discuss current developments and topical issues, sometimes inviting specialists from outside the WPDD;
  • identify the main lessons to be reported to the WPDD;
  • discuss and co-ordinate the programme of work.

The work of the group is complementary to that of the International Atomic Energy Agency (IAEA) and the European Commission, and will provide input for the activities of also these institutions. Co-operation is sought with them.

DCEG may convene expert groups to work on topics of particular interest. In an joint undertaking with IAEA, an expert group under DCEG focus currently on uncertainties in decommissioning cost estimation. The report is expected to be published in early 2017.
