MIT<\/strong> researchers have developed a model that predicts the behavior of plasma in tokamak reactors<\/strong> by combining physics and artificial intelligence<\/a><\/em><\/strong>. The method has been tested and proven successful.<\/p>\n\n\n\n

Researchers at the Massachusetts Institute of Technology (MIT)<\/strong> have announced that they have crossed a major threshold on the path to making nuclear fusion<\/strong> a scalable energy source. Scientists have developed a model that can predict the behavior of plasma<\/strong> in tokamak reactors<\/strong> by combining the laws of physics<\/strong> with machine learning<\/strong>. This is critical for making fusion reactors, which replicate the energy production process of stars on Earth, safer, more efficient, and more sustainable.<\/p>\n\n\n\n

A tokamak<\/strong> is one of several fusion reactor designs with a donut shape that confines extremely hot plasma<\/strong> using strong magnetic fields<\/strong>. However, one of the biggest challenges in these systems is controlling the plasma current<\/strong> and safely slowing it down once the reaction has started. The method developed by the MIT<\/strong> team makes this complex process predictable<\/strong>.<\/p>\n\n\n\n

When a tokamak reactor<\/strong> operates at full capacity, the plasma current<\/strong> moves at a speed of approximately 100 kilometers per second<\/strong> and reaches 100 million degrees Celsius<\/strong>, which is even hotter than the Sun’s core. Due to these extreme conditions, reactors cannot be shut down abruptly. The shutdown process is carried out through a gradual cooling process. However, this process can cause scratches and wear on the inner surface of the reactor due to intense heat fluxes.<\/p>\n\n\n\n

Stating that fusion experiments are still expensive and such tests can only be performed a few times a year, the team adopted an innovative approach to overcome the lack of data. They combined the machine learning algorithm<\/strong> with fundamental physics models<\/strong> and trained the system with data obtained from the experimental fusion reactor called TCV (Tokamak \u00e0 Configuration Variable)<\/strong> in Switzerland. This data included the plasma’s initial temperature, energy levels, and the changes it underwent during the experiment.<\/p>\n\n\n\n

The research team used this information to create “plasma trajectories<\/strong>” that guide the reactor operators. These trajectories enabled operators to safely shut down the device by predicting how the plasma<\/strong> would behave throughout the reaction. The model was tested repeatedly in experiments conducted on the TCV<\/strong> and made it possible to cool the reactor more stably.<\/p>\n\n\n\n
