South Korean scientists have achieved a new world record by successfully operating the KSTAR nuclear reactor, also known as the “artificial sun,” at a temperature of 100 million degrees Celsius for 48 seconds.
Continuing their work on nuclear fusion technology to obtain clean energy, South Korean scientists have set a new world record. A group of researchers from the Korea Fusion Energy Institute (KFE) successfully operated the KSTAR (Korean Superconducting Tokamak Advanced Research) nuclear reactor, also known as the “artificial sun,” at a temperature of 100 million degrees Celsius, which is 7 times hotter than the Sun’s core, for 48 seconds. The team surpassed the previous world record of 30 seconds, set in 2021. KSTAR Director Si-Woo Yoon stated that maintaining such high temperatures for an extended period is not easy, making the 48-second record significant. Yoon emphasized that their ultimate goal is to operate the KSTAR reactor at the same temperature for 300 seconds by 2026.
Scientists aim to mimic fusion reactions occurring in the Sun with the KSTAR reactor, which is still in the experimental stage, to produce unlimited and clean energy.
