KSTAR Achieves 102 Seconds of Plasma Confinement in Nuclear Fusion Breakthrough
KSTAR, South Korea's artificial sun, successfully sustained plasma for 102 seconds while maintaining a temperature of 100 million degrees Celsius for 48 seconds. This progress moves the industry closer to achieving clean fusion energy, marking a significant step toward a sustainable power source.

KSTAR, operated by the Korea Institute of Fusion Energy, achieved a notable milestone by maintaining high-confinement plasma for 102 seconds. During the 2023-2024 plasma campaign, it also sustained a temperature of 100 million degrees Celsius for 48 seconds, utilizing advanced tungsten divertor technology.
This development is critical as it signifies a step towards clean fusion energy, which can potentially provide unlimited electricity with minimal carbon emissions. The reactor's success with tungsten divertors allows for higher temperature operations and longer plasma pulses, essential for future research goals of sustaining plasma for 300 seconds. The advancements in fusion technology could position it as a viable alternative to fossil fuels, promoting environmental sustainability.
