The Korea Institute of Fusion Energy ( KFE ) has started a series of plasma experiments in 2024 for the development of advanced fusion reactor operation technologies. These experiments are designed to optimize the high-density, high-temperature, and high-current scenarios, which are very important for achieving advanced plasma confinement.
Research advances in plasma experiments
The main research focus is the control of tungsten impurities in plasma. For example, tungsten is an ideal material for coating reactor walls due to its heat resistance, but its use can generate impurities that negatively affect plasma stability and performance.
Furthermore, KSTAR is focusing on developing solutions to control these impurities by improving tungsten diverters as well as adjusting the magnetic field to detect and reduce impurity build-up.
The research institute is conducting more than 40 collaborative experiments with international partners, including device research teams such as DIII-D in the United States and WEST in France.
These collaborations extend to Japan, China, the United Kingdom and the Czech Republic, with the aim of improving next-generation fusion scenarios. KSTAR Research Center Director Dr. Yong Un Nam highlighted the importance of these collaborations in solving the complex challenges of fusion energy.
