SAPIERR: Evaluating the Framework for Shared Nuclear Repositories in Europe
As Europe navigates the complexities of a low-carbon future, the management of high-level radioactive waste (HLW) from nuclear power generation remains a critical challenge. While geological disposal is globally recognized as the safest long-term solution, implementing national repositories is technically and financially daunting for many countries, especially those with small nuclear programs.
The SAPIERR project (Support Action: Pilot Initiative for European Regional Repositories) was launched to address this, exploring the potential for shared, regional solutions to nuclear waste disposal. The Context: Why Shared Repositories?
For decades, the default position has been that every nation with a nuclear program must be responsible for its own waste, disposing of it within its own borders. However, this approach presents significant challenges:
High Costs: Constructing deep geological repositories requires vast financial investment.
Technical Expertise: Small nuclear countries often lack the specialized resources required for repository siting and development.
Safety & Security: Concentrating waste in fewer, specialized locations rather than fragmented national sites could offer enhanced safety and lower security risks.
SAPIERR was established under the European Commission’s 6th Euratom Framework Programme in 2003 to investigate whether regional repositories—shared by multiple nations—could overcome these challenges. SAPIERR: Evaluating the Framework
The SAPIERR project, led by a consortium including DECOM Slovakia and ARIUS (Association for Regional Initiatives for Safe Nuclear Disposal), aimed to:
Bring together European countries interested in exploring shared disposal options.
Evaluate the economic, safety, and regulatory feasibility of regional repositories within the EU.
Propose a pilot project to demonstrate the feasibility of the concept.
SAPIERR recognized that implementing 25+ individual national repositories across Europe is not economically or technically optimal. Instead, they proposed that a smaller number of regional repositories—potentially handling spent fuel and high-level waste from several smaller European nations—could provide a superior, safer, and more cost-effective alternative. Evolution of the Concept: From SAPIERR to ERDO
Following the initial feasibility studies, the work of SAPIERR and subsequent projects directly influenced the formation of the European Repository Development Organisation (ERDO) Working Group.
This group, established in 2009, brought together 14 EU countries to collaborate on the concept of shared disposal, focusing on:
Developing legal frameworks for transporting and storing radioactive waste across borders. Defining the criteria for hosting a regional facility.
Engaging with the public and local communities in the planning process. Current Status and Challenges
While the concept offers significant advantages, it faces political challenges. Currently, there is a clear understanding that each country is responsible for its own waste. However, international organizations like the IAEA have noted that a shared repository can act as a “surrogate” to meet this legal and ethical responsibility.
While some reports suggested in 2019 that multinational repositories might not be timely until national projects are more advanced, the foundational work of SAPIERR proved that shared disposal is a technically sound, safety-focused concept that continues to be a viable long-term solution for European nuclear waste management. Conclusion
SAPIERR successfully shifted the conversation from purely national repositories to a more collaborative approach. By evaluating shared repository frameworks, the project laid the groundwork for a more efficient, secure, and sustainable future for high-level nuclear waste management in Europe, demonstrating that cooperation can enhance safety and security across the continent.
