Mandate:

The NEA conducts important international activities to support its member countries in the development of strategies concerning the application of nuclear technologies. As reflected in the NEA Strategic Plan for 2017-2022, the Agency’s goals include providing governments and other relevant stakeholders with authoritative, reliable information on the political, strategic and regulatory aspects of decommissioning nuclear installations. In addition, the Agency conducts on-going work supporting the efforts of the member countries to develop strategies to manage nuclear legacy sites and installations.

In order to effectively integrate the Agency’s activities, the Committee on Decommissioning of Nuclear Installations and Legacy Management shall conduct work related to the activities of the NEA concerning the decommissioning of nuclear facilities and management of legacy sites contaminated resulting from historical radiological activities. In this context, the Committee shall:

i) provide a forum for experts, representing national agencies with policy and programme responsibilities in decommissioning, regulatory authorities, policy-making bodies, decommissioning implementers, research institutes and other interested stakeholders, to facilitate the exchange of experience and information on policies and practices in the areas of decommissioning and legacy management between NEA member countries, and to advance the state of the art on technical, environmental, policy, financial and societal aspects in these areas;

ii) advance and develop international understanding and guidance, in support of national authorities, to address questions of common concern regarding concepts, policies, regulatory frameworks, strategies for decommissioning and legacy management. In doing so, the Committee will collaborate with the Radioactive Waste Management Committee (RWMC) and Regulators’ Forum (RF) to ensure safe and efficient management of all radioactive waste taking into account current practices in radioactive waste management. In particular, the RF will support Committees to address regulatory challenges and issues in the area of (i) radioactive waste management and disposal; and (ii) decommissioning and dismantling including legacy management;

iii) share and further develop concepts, policies and approaches for reaching accepted and sustainable decisions on decommissioning and legacy site end-state aspects aiming at reducing the burden on current and future generations from facility decommissioning and remediation; in particular to keep under review the developments in the optimisation of decommissioning strategies bringing in balance technical, economic, safety and ethical aspects;

iv) enhance worker and public safety, and environmental protection by developing, in relation the Committee on Radiological Protection and Public Health (CRPPH) and its Expert Group on Legacy Management (EGLM), practical radiation protection guidance to manage nuclear legacy sites and decommissioning. While nuclear legacy liabilities are often responsibilities assumed by a Government or liabilities that are not covered by current waste management funding arrangements, nuclear legacy situations can vary significantly from country to country. In developing future work scope to address specific nuclear legacy management objectives, the Committee shall clearly define the definition of “legacy waste” in its Mandate;

v) further develop approaches for the estimation of decommissioning project costs by improving understanding of the risks associated with financial consequences in regards to cost estimating and financing; and decommissioning planning for uncertainties, with an overall aim to assist member organisations to develop robust project management throughout the decommissioning process;

vi) in co-ordination with the Forum on Stakeholder Confidence (FSC) share experience and further develop considerations addressing issues of public concern and conflict management during decommissioning and legacy site management. Similar to the RF, the FSC will support both the RWMC and the CDLM in addressing social challenges in long-term radioactive waste management, decommissioning and legacy management;

vii) regularly exchange experience and lessons on those decommissioning practices worldwide;

viii) advise the NEA in its collection, analysis dissemination of major information in decommissioning and legacy management at both national and international levels, and help ensure the management of decommissioning and legacy-management knowledge and experience between generations of experts;

ix) offer, upon request, a framework for the conduct of international peer reviews of national activities in the fields of decommissioning and legacy management.

In fulfilling its Mandate, the Committee will be primarily supported by the staff of the NEA Division of Radioactive Waste Management. The Committee will co‑operate with other NEA standing technical committees, in particular, the Radioactive Waste Management Committee (RWMC), the Committee on Radiological Protection and Public Health (CRPPH) and their relevant working groups. The Committee will also co-operate with the NEA Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning Projects (CPD), and as necessary with other NEA programmes, its counterparts in the European Commission (EC), the International Atomic Energy Agency (IAEA) and other international organisations on matters of common interest. To ensure efficient collaboration, coordination, and exchange of information; the coordination between this new standing technical committee and other NEA committees and/or their sub-groups could be provided through joint sessions at the annual meetings and/or joint bureau meetings of the involved committees.

The Committee may set up subsidiary bodies to facilitate the achievement of its goals, invite experts in other fields to attend its meetings and sponsor meetings of specialists. In designing its work programme and activities, the Committee will establish co-operative mechanisms with its counterparts to address cross-cutting issues and to avoid unnecessary duplications of work of other committees or organisations.
