The NEA Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning Projects (CPD)

The International Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning Projects is a joint undertaking of a limited number of organisations mainly from NEA member countries. The objective of the CPD programme that was launched in 1985 is the exchange and sharing of information from operational experience in decommissioning nuclear installations that is useful for current and future projects. Initially consisting of 10 decommissioning projects in eight countries, the programme has since grown to the present number of 70 projects (40 reactors and 30 fuel cycle facilities) in 14 NEA member countries, one non-member economy and the European Commission. The current agreement is valid from 2014 to 2018. Of particular importance in this period is the increase in membership and active participating projects from NEA and non-NEA/non-OECD member countries. In addition to fostering and enhancing the cooperation with the NEA/RWMC Working Party on Decommissioning and Dismantling (WPDD), is an envisaged goal in order to meet the need of harmonisation and mutual information.

Experience has already shown that beginning the discussions on technical details between implementers at CPD before having a dialogue with regulators and policy makers may significantly change key factors towards successful, safe and efficient decommissioning of nuclear installations in the future. This also shows that the increasing importance of the exchange between key players in decommissioning is now being recognised for the future success of the nuclear industry.

Decommissioning projects have benefited from the information exchange framework provided by the CPD. The information exchange includes biannual meetings of the Technical Advisory Group (TAG) during which the site of one of the participating projects is visited, and where positive and less positive examples of the decommissioning experience are openly exchanged for the benefit of all. If needed, the TAG convenes task groups to work on topics of interest. In 2014, the Task Group on Nuclear Site Restoration completed their work with the publication of their report entitled "Nuclear Site Remediation and Restoration during Decommissioning of Nuclear Installations" which addressed technical aspects of nuclear site remediation. A new task group has been formed to update the report on "Recycling and Reuse of Scrap Metals" from 1996 to take 18 additional years of experience into account and cover all materials arising from nuclear installation decommissioning.

The forum offered by the CPD programme is valuable in ensuring that the safest, most economic and environmentally-friendly options for decommissioning are employed. For some members who have less experience in this area, the benefit in not having to go through an expensive learning and development programme is invaluable.

The programme reports to the NEA Radioactive Waste Management Committee (RWMC) and has strong ties to the NEA/RWMC Working Party on Decommissioning and Dismantling (WPDD). Reports providing basic information on the participating projects, their modus operandi and summarising the experience accumulated through the project are as follows:
