What is a Deep Geological Repository (DGR)?

A Deep Geological Repository (DGR) is a state-of-the-art engineered facility designed for the secure and long-term management of used nuclear fuel, also known as spent fuel. Located several hundred meters below the Earth’s surface, typically within stable geological formations like granite or clay, the DGR serves as both a storage and research facility, ensuring the safety of both the environment and the public.

Key Features:

  1. Multi-Barrier System: At the core of the DGR’s safety design is the multi-barrier approach. This system employs both engineered and natural barriers to robustly contain and isolate the radioactive material. Engineered barriers include corrosion-resistant waste containers and layers of sealing materials such as bentonite clay, while the geological formation itself serves as a natural barrier.
  2. Passive Safety: The DGR is designed to be passively safe, meaning it doesn’t rely on active human intervention for maintaining safety conditions. Its engineered and natural barriers are meant to securely isolate the spent fuel, whether for long-term storage or future research.
  3. Location-Specific Design: The DGR is tailored to the unique geological, hydrological, and environmental attributes of its site. Comprehensive studies are undertaken to ascertain long-term stability and safety.
  4. Continuous Monitoring and Oversight: While passive safety features are a cornerstone of the DGR, ongoing monitoring and oversight are integral to ensuring the repository’s continued performance against the highest safety benchmarks.
  5. Regulatory Compliance: The planning, construction, and operation phases of a DGR are strictly governed by relevant regulatory bodies to meet or exceed all safety and environmental standards.
  6. Research & Development: Unlike traditional DGRs that focus solely on isolation, our DGR also serves as a cutting-edge research facility. This allows for ongoing study and potential reutilization of used nuclear fuel, thereby increasing its future value.
  7. Community Engagement: Transparency and open dialogue with local communities, stakeholders, and regulatory authorities are central to our approach. Through continuous consultations, we aim to share information, address concerns, and integrate feedback.

By incorporating these principles and features, our DGR is more than just a storage facility; it is a dynamic resource for ongoing research and potential future energy solutions. This design paradigm is committed to the long-term safeguarding of both human health and the environment for current and future generations.
