# France’s Cigeo Project: Safeguarding Energy’s Future

Cigeo is France’s groundbreaking deep geological disposal facility designed to safely store the most hazardous radioactive waste generated by its extensive nuclear power program. Located 500 meters underground in the stable clay formations of the Grand Est region, Cigeo will protect people and the environment for hundreds of thousands of years.

How does Cigeo add value to energy generation and the energy system?

🔹Enabling nuclear energy sustainability: By securely managing high-level and long-lived intermediate-level radioactive waste, Cigeo ensures that nuclear power remains a viable, low-carbon energy source, supplying about 70% of France’s electricity with minimal greenhouse gas emissions.

🔹Long-term environmental safety: The facility’s engineered design and geological barriers will isolate waste safely for over 100 years, preventing environmental contamination and allowing France to meet stringent safety and environmental standards.

🔹Supporting energy independence: Safe waste disposal underpins France’s energy sovereignty by enabling continued operation and eventual decommissioning of nuclear plants without transferring risks to future generations.

🔹Economic and social benefits: The project creates regional jobs and infrastructure investment while addressing public concerns through transparency and reversibility options, fostering social acceptance essential for nuclear’s future.

🔹Technological leadership: After 30+ years of multidisciplinary research at the Meuse/Haute-Marne Underground Laboratory, Cigeo represents cutting-edge expertise in radioactive waste management.

🔹Financial responsibility: Funded by nuclear waste producers, Cigeo’s cost (now estimated between €26 billion and €37.5 billion) is a small fraction of the overall cost of nuclear-generated electricity, ensuring the burden is managed responsibly today, not deferred to future generations.

Cigeo is a vital pillar enabling France’s clean energy transition. It balances the benefits of nuclear power with responsible, long-term waste management.
