Decommissioning of Garoña Nuclear Plant: A Model for Future Nuclear Closures
The decommissioning of the Garoña nuclear power plant in Spain marks a significant milestone in the transition from nuclear energy. This extensive process is not only about dismantling infrastructure but also about establishing a new sector focused on nuclear decommissioning services, with implications for the broader energy transition in Europe.

The Garoña nuclear power plant is undergoing a complex decommissioning process led by Enresa, aimed at ensuring long-term radiological safety and transitioning the site to 'green field' status. The HI-STORM FW system will manage spent fuel, designed to withstand environmental and seismic challenges.
This project represents a financial burden projected in the hundreds of millions of euros, supported by current electricity consumers. The expertise gained is positioning Spain as a leader in the emerging Nuclear Decommissioning Economy, attracting interest from countries like Germany and France.
The collaboration between state entities and environmental groups, such as Greenpeace, highlights a unique alignment in ensuring safety throughout the process. As Spain navigates its energy transition, the successful decommissioning of Garoña may serve as a model for future nuclear plant closures across Europe, emphasizing the importance of managing the legacy of nuclear infrastructure.
