The future of nuclear energy has returned to the media and political spotlight in Spain and other European countries. With upcoming decisions on the gradual closure of power plants and international pressure to strengthen energy security, public debate is intensifying, bringing to the fore multiple technical, social, and economic issues affecting citizens and the industrial fabric.
In the midst of the transition towards more sustainable energy models, the role of nuclear energy It sparks highly polarized opinions. The Spanish nuclear shutdown schedule, radioactive waste management, and the possible extension of plant life are issues that confront political parties, local associations, and experts, while in other countries, old prohibitions are being reviewed and new technological solutions are being explored.
The political and social landscape: open debate on closure and continuity
The positions regarding the extension or closure of nuclear power plants The decisions taken vary by region and political sensitivity. In areas such as Extremadura, the possible closure of the Almaraz plant has mobilized thousands of residents and workers, who see this infrastructure as a fundamental pillar for local employment and development. Recent polls show that support for maintaining the plant is overwhelming, although the national positions of political parties tend to be more cautious and, at times, contradictory to the decisions of the regional delegations.
The central government, under pressure from decarbonization commitments and European energy policy, maintains a vigilant stance: any revision of the nuclear timetable It must ensure that it does not negatively impact consumers or the public budget. The electricity companies express their willingness to comply with these conditions, while the affected workers and municipalities seek solutions that allow them to maintain their activity and not jeopardize the social and economic stability of the area.
In Catalonia, the situation also presents challenges. The Ascó and Vandellòs plants provide a significant portion of the region's electricity generation, which has led parties traditionally critical of nuclear energy to reconsider their stance on the risk of shortages. This standoff is being repeated in other regions, where the uncertainty about the phased closure It confronts the needs of security of supply with the guidelines of ecological transition.
Political tensions are also evident in Europe, where countries like Belgium and France are opting to extend the lifespan of their reactors, and the European Commission is considering nuclear energy as part of the "green taxonomy" under strict safety and waste management conditions.
High performance and stability, but with pending challenges
According to the most recent data, the Nuclear energy is the technology that operates at its maximum capacity for the longest number of hours. in the Spanish electricity system. During the last full year, nuclear power plants were operational nearly 84% of the time, far exceeding other sources of generation, including renewables. This high efficiency contributes decisively to the stability and security of the energy supply.
However, nuclear energy is still not legally recognized as a renewable energy source in Spain or the European Union, which excludes it from incentives aimed at other clean technologies. National legislation focuses on promoting renewables and scheduling the closure of nuclear power plants between 2027 and 2035, strengthening a decarbonized energy system, but neglecting the specific benefits and problems of nuclear energy.
Despite this, nuclear energy remains a key tool in energy security plans from multiple countries, especially after incidents such as the blackout in Spain, which demonstrate the importance of having sources that guarantee continuous and safe power.
Global resurgence and technological advances in waste management
Outside Spain, the Nuclear energy is experiencing a revitalization process At the international level. The International Energy Agency indicates that more than 40 countries are promoting projects to triple global nuclear capacity, primarily to reduce emissions. Eastern European countries, such as Poland, are developing large-scale nuclearization plans, supported by Spanish companies specializing in engineering and construction.
Waste safety and management remain significant challenges. Recent research has developed new tools to better understand the long-term behavior of radioactive waste. Advanced simulation technologies allow for the analysis of the interaction of these materials with their environment, including infrastructure and geological formations where they will be confined for centuries or millennia. These advances are crucial for improving planning and reducing the risks associated with waste storage—one of the most common arguments used by critics of nuclear energy.
Radioactive waste management requires dialogue and transparency. Institutions and experts agree that, in addition to technological solutions, a solid legal framework and international cooperation are essential to ensure safe treatment adapted to climatic and social variations.
New legislation, innovation and the role of security
The European Union has adopted an intermediate classification for nuclear energy: it does not consider it renewable, but it does include it on its list of climate-sustainable activities, provided it meets strict safety and waste management requirements. Spain, for its part, has made progress along these lines, banning new nuclear projects and establishing the gradual closure of existing plants through Climate Change Law 7/2021.
Experts believe that the future of nuclear energy must balance the ecological transition with the stability of the electrical system, promoting safer and more efficient technologies and fostering a diverse and science-based social debate. They also emphasize the importance of maintaining qualified personnel to operate, decommission, and monitor facilities, as well as a safety culture capable of anticipating and managing potential incidents.
