Abstract
Nuclear fusion is the fundamental nuclear reaction that powers stars, and it is currently being considered as a potential method for energy production. Harnessing nuclear fusion poses a global challenge due to the difficulty of replicating the ideal conditions for these reactions on Earth. These conditions are partially reproduced inside machines called Tokamaks through the use of a localized magnetic system, where the fusion fuel (plasma heated to approximately 100 million degrees Kelvin) is magnetically confined. The power production levels achieved in the confined area, combined with the limited surface area of the Plasma Facing Components (PFCs), make managing the thermal load on the wall very challenging, threatening the integrity of the materials used.
This phenomenon is referred to as the power exhaust problem and is one of the fundamental challenges in designing a future fusion reactor
