In Spain, a groundbreaking project is capturing the attention of the scientific community, driven by the ambitious goal of achieving sustainable energy through nuclear fusion.
The innovative reactor, known as SMall Aspect Ratio Tokamak (SMART), is being constructed at the University of Seville.

This initiative is a collaboration between the university and the Princeton Plasma Physics Laboratory (PPPL) in the U.S.
Nuclear fusion holds the promise of generating vast amounts of energy by mimicking the processes that power stars.
Unlike nuclear fission, which splits atoms, fusion combines hydrogen atoms to form helium, releasing energy in the process.
This method offers significant advantages, producing less waste and posing fewer safety risks compared to traditional nuclear power solutions.
Although fusion energy has been pursued for decades, it has eluded practicality due to the challenge of producing more energy than consumed.
However, the SMART fusion reactor is part of the latest wave of innovations aiming to address these hurdles.
It incorporates cutting-edge technology that distinguishes it from past efforts.
Professor Manuel Garcia-Munoz from the University of Seville elaborates on the novel features of SMART.
The reactor’s design employs a spherical tokamak structure combined with negative triangularity.
This combination could potentially enhance the reactor’s performance by suppressing plasma instabilities, which are crucial for efficient and safe energy production.
Negative triangularity helps lower fluctuation levels within the plasma while also increasing the divertor area, which disperses heat exhaust more effectively.
“It’s a potential game changer,” notes Professor Garcia-Munoz.
This innovation could pave the way for more compact fusion reactors with improved energy outputs.
The joint endeavor between the University of Seville and PPPL has brought technical expertise together, notably in fields like magnetics and sensor systems.
These technologies are crucial for maintaining plasma stability and minimizing impurities, essential steps in refining fusion processes.
Tools developed through this partnership are currently assessing plasma stability as the SMART experiments advance.
The researchers aim to achieve the first plasma—a foundational step towards fully operational fusion—by the end of 2024.
As developments continue, the potential for fusion energy to power global energy grids comes ever closer to reality.
Overall, the SMART project exemplifies the strides being made towards a future where clean and efficient energy is not just a concept, but a practical solution to meet the world’s energy demands.
The scientific community remains hopeful that with ongoing collaboration and innovation, the dream of harnessing fusion power is nearing fruition.
