Managing nuclear waste is one of the most critical challenges faced by countries leveraging nuclear power. With the rise in commercial nuclear energy production globally, nearly every nation operating reactors is formulating plans to safely contain and isolate waste byproducts from their nuclear fuel cycle deep underground. This approach aligns with internationally recognized best practices for long-term nuclear waste management.
Canada’s Leadership in Nuclear Waste Management
Canada stands out as a beacon of innovation in nuclear waste management, primarily through the efforts of the Nuclear Waste Management Organization (NWMO). This organization is not only responsible for the safe handling of Canada’s nuclear waste but also collaborates extensively with various international counterparts to share insights and technologies essential for developing effective deep geological repositories.
The NWMO is currently engaged in a regulatory process aimed at establishing a deep geological repository for used nuclear fuel. This facility will rely on a combination of engineered and natural barriers designed to securely contain and isolate the waste for thousands of years. Such meticulous planning ensures that the safety and environmental impacts of nuclear waste are diligently addressed.
International Co-operation
One of the hallmarks of the NWMO’s strategy is its commitment to international collaboration. The organization has signed cooperation agreements with various nations, including Australia, Belgium, Finland, France, Japan, South Korea, Sweden, Switzerland, the United Kingdom, and the United States, along with a memorandum of understanding with Taiwan. This web of partnerships allows for a rich exchange of knowledge and best practices across borders.
- Fostering international cooperation in technology development and demonstration.
- Learning from the experiences and challenges faced by other countries.
- Keeping updated on new developments in repository design and safety measures.
EDRAM: A Global Forum for Safe Disposal
The NWMO, along with several international partners, is a member of the International Association for Environmentally Safe Disposal of Radioactive Materials (EDRAM). This forum serves as a crucial platform for countries to discuss and develop practices related to the long-term storage of used nuclear fuel.
“Through EDRAM, we exchange experiences and insights, learning from one another’s successes and challenges,” said Laurie Swami, President and CEO of NWMO. This collaborative spirit deeply enriches the understanding and innovation surrounding nuclear waste management, ensuring that organizations stay ahead in terms of safety and effectiveness.
One of the greatest advantages of EDRAM is the capacity to operate within a global community that has faced similar challenges. Members can compare safety methodologies, refine geological models based on real-world data, and adapt successful engagement strategies from other implementations.
Global Case Studies in Nuclear Waste Storage
Finland is currently the frontrunner in the establishment of a deep geological repository with its ONKALO facility, which is in the licensing stage and expected to open soon. This advanced facility stands as a testament to decades of rigorous research and dedicated planning.
In Sweden, after roughly 40 years of research and development, groundbreaking took place in 2025 for a deep geological repository at Forsmark, Sweden’s largest nuclear power plant. This initiative is set to become operational in the upcoming decade.
2023 was a milestone year as the NWMO congratulated France’s radioactive waste management agency (Andra) on submitting its license application for the Cigéo repository, designed to securely store the country’s used nuclear fuel near Bure. This development signifies advancements in French nuclear waste management practices.
In Switzerland, the National Cooperative for the Disposal of Radioactive Waste (Nagra) has made substantial strides in its quest to develop a safe repository, announcing the Nördlich Lägern site as the preferred location. Operations for low- and intermediate-level waste are planned for 2050, with high-level waste management slated for 2060.
The NWMO has eagerly shared its experience in consent-based site selection with countries like the United Kingdom and Japan, which are navigating similar pathways toward establishing their own repositories.
The Path Forward
The NWMO anticipates continuing its journey alongside international partners as it advances Canada’s efforts to create a comprehensive deep geological repository. The importance of effectively managing used nuclear fuel cannot be overstated; international collaboration is crucial for ensuring that future generations inherit a safe and sustainable landscape when it comes to nuclear waste.
About the NWMO
Founded in 2002, the Nuclear Waste Management Organization (NWMO) operates as a not-for-profit entity dedicated to the long-term management of Canada’s high-level and intermediate radioactive waste. Its mission is guided by a team of experts, scientists, engineers, and Indigenous Knowledge Holders, all committed to innovating collaborative solutions for nuclear waste stewardship that prioritizes both human safety and environmental protection.
