The NEA Co-operative Programme for the Exchange of Scientific and Technical Information on 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 ten decommissioning projects in eight countries, the programme has since grown to the present number of 71 projects (40 reactors and 31 fuel cycle facilities) in 14 NEA member countries, one non-member economy and the European Commission. The current agreement is valid from 2019 to 2023.

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. Another task group had been formed to update the report Recycling and Reuse of Scrap Metals from 1996 by taking an additional 18 years of experience into account to cover all materials arising from nuclear installation decommissioning. They published a report in 2017. A new task group focused on dismantling of highly contaminated tanks had been established in 2017 to continue experience exchange among members.

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 of not having to go through an expensive learning and development programme is invaluable.

The CPD currently reports to the NEA Committee on Decommissioning of Nuclear Installations and Legacy Management (CDLM). Before 2019, the programme reported to the NEA Radioactive Waste Management Committee (RWMC) and had strong ties to the NEA RWMC Working Party on Decommissioning and Dismantling (WPDD). Reports providing basic information on participating projects, their modus operandi and summarising the experience accumulated through the project are as follows:
