Earlier this year, the IAEA published a comprehensive report looking at cooperative approaches throughout the back end of the nuclear fuel cycle. Work for this report started back in 2015, in the scope of the IAEA INPRO Programme. The completion of the task involved almost 50 contributors and reviewers, based on 6 separate consultant meetings in Vienna: it is the culmination of enormous effort and incorporates significant expertise. ERDO Members, including Leon Kegel, Neil Chapman and Charles McCombie, were heavily involved in the drafting and reviewing of the document, forming part of the United States Department of Energy team that was established to support the project. The scope of the report is ambitious, it covers the potential for cooperation in all aspects of the back end of the fuel cycle, including spent fuel storage, transportation, reprocessing, recycling, encapsulation and final disposal. The objective was to look at both drivers and impediments to each area of potential cooperation that was studied.

The chapters of most direct interest to ERDO are Chapter 6, on The Multinational Repository Concept, and Chapter 7, on Cooperative Approaches Involving Spent Nuclear Fuel Take-back and Take-away. Much of the interesting and relevant material is relegated to a series of nine Annexes, at a combined seventy pages in length. Nevertheless, the material on multinational repositories contains details which remain novel and highly relevant in the context of our mission at ERDO, and Chapter 6 deserves to be investigated further:

6      The Multinational Repository Concept

6.1. Roles Of Multinational Cooperation in MNR Development

6.2. Key Characteristics of the MNR Concept

6.3. Drivers and Benefits Associated with the Development of a Multinational Disposal Service

6.3.1. Overview of drivers and incentives for cooperating in MNR development

6.3.2. Previous discussions on incentives

6.3.3. Potential benefits for a provider of an MNR service

6.4. Impediments to Realisation of an MNR and Potential Mitigation Measures

6.4.1. The importance of a policy framework

6.4.2. Securing an enduring commitment to develop an MNR

6.4.3. Constructing an open and interactive political and public engagement programme

6.4.4. Legal considerations

6.4.5. Agreeing a costing, financing, and pricing structure

6.4.6. Assurance of a viable market for the disposal service

6.4.7. Developing a repository siting strategy

6.4.8. Building a competent and balanced team

6.4.9. Cooperation with international organizations, national disposal programmes and peer groups

6.5. Summary of Drivers and Impediments

Among the Annexes, several are worthy of greater attention, and warrant consideration from stakeholders with an interest in multinational solutions for radioactive waste management: Annex I gives a comprehensive, 6-page history of the development of multinational cooperation concepts – from the first proposals in the 1940s through to the present day; Annex IX takes a detailed look at legal issues; Annex VI presents a comprehensive discussion of complex stakeholder issues involved in attempts to implement multinational projects; and Annex VIII contains hitherto unpublished material assessing the commercial market that could be open for multinational services, should they be on offer.

Despite the long delay in its publication, this report appears at a useful time, given the resurgence of interest in multinational cooperation, as illustrated by recent news we discuss in detail elsewhere: the emergence of a Forum on Joint Approaches to Radioactive Waste Management (FoJARM) in response to a request from the European Parliament.
