The National Fusion Research Institute of Korea has succeeded in raising the temperature of the KSTAR, known as the artificial sun of Korea, to 100 million degrees Celsius. In doing so, Korea has secured competitive edge in the field of nuclear fusion.

The inside of a tokamak, a nuclear fusion device, is filled with red light as hot plasma is being formed. The center of the plasma appears translucent. The ion temperature surpasses 100 million degrees in 1.5 seconds. It's the first time that the plasma ion temperature was raised to over 100 million degrees using a superconductive device.

[Soundbite] Yoon Si-woo(National Fusion Research Inst.) : "It's a meaningful milestone. By raising the temperature to 100 mn degrees, we have created plasma for nuclear fusion."

High temperatures and uninterrupted long-term operations are the two essential prerequisites of nuclear fusion, which operates under the same principle as the sun. The plasma must be maintained at over 150 million degrees for at least 300 seconds. Research into long-term plasma operation is currently underway. Last year, uninterrupted operation was extended to nearly 90 seconds at 70 million degrees of electron temperature. With the breakthrough achievement in plasma operation, Korea is expected to play a pivotal role in nuclear fusion experiments conducted jointly by seven countries, including the U.S. and France.
