The Committee on Decommissioning of Nuclear Installations and Legacy Management (CDLM) was created in 2018 following the request from Nuclear Energy Agency (NEA) member countries to enhance the NEA’s visibility in nuclear decommissioning and legacy management. Although the first NEA programmes on decommissioning already date back to 1978, the creation of the CDLM reflects the Agency’s goals in providing governments and other relevant stakeholders with authoritative, reliable information on the political, strategic and regulatory aspects of decommissioning and legacy management. The committee also aims to achieve collaborative advance of the state of the art of technical, environmental, policy, financial and societal aspects in its areas of work.

The committee provides a forum for international senior experts representing national agencies with policy and programme responsibilities, regulatory and implementer authorities, operators, service providers, research institutes and other relevant stakeholders to exchange experience and information. Broadly, the topics of interest of the CDLM include:

  • decommissioning and dismantling of various nuclear facilities (e.g. radioactive waste and spent fuel storage facilities, spent fuel reprocessing facilities or other nuclear installations) and all reactor types
  • development of practical guidance on regulating and managing legacy waste, waste sites and releases of legacy sites.

Members of the CDLM consist of NEA member countries as well as the European Commission (EC). There is close collaboration with the International Atomic Energy Agency (IAEA), which participates in the work of the committee as an observer.

The CDLM applies a holistic as well as a sustainable approach to dealing with decommissioning and legacy management. In this way, the CDLM systematically identifies its activities by focusing on four aspects of decommissioning and legacy management: 1) regulatory and legal; 2) environmental and operational safety; 3) economic; and 4) societal. 

Some outcomes related to decommissioning and legacy management from the former Working Party on Decommissioning and Dismantling (WPDD) in the Radioactive Waste Management Committee (RWMC) are listed for reference.

The NEA Division of Radioactive Waste Management and Decommissioning (RWMD) supports the Committee on Decommissioning of Nuclear Installations and Legacy Management (CDLM) in conducting international peer reviews and providing expert feedback to ensure that best practices in regulatory and technical methodologies are adopted in decommissioning and legacy management.

Structure

As of 2019, the Regulators' Forum (RF) supports both the CDLM and the Radioactive Waste Management Committee (RWMC) to undertake regulatory challenges in radioactive waste management and nuclear decommissioning and legacy management.

The Forum on Stakeholder Confidence (FSC) also supports both the RWMC and the CDLM committees as of 2019. The FSC assists both committees to address societal issues related to radioactive waste management, decommissioning and legacy management.
