KSTAR is setting the world record for ultra-high temperature plasma driving every year since raising the plasma temperature to 100 million degrees for the first time in 2018 and maintaining it for 1.5 seconds. [...] The fusion reactor aims to reach the stage of maintaining 100 million degrees of plasma at KSTAR for more than 300 seconds by 2025. "Most of the physical variables that act as obstacles to commercialization appear within 300 seconds after the plasma temperature rises to 100 million degrees." It means that it is no different from that.” It means that commercial development is possible only after reaching this stage. Director Yoon added, "We plan to maintain it until 30 seconds next year, and then achieve 50 seconds in 2023, 100 seconds in 2024, and 300 seconds in 2025 through facility upgrades."
