Nuclear Fusion: KSTAR reaches a temperature of 100 million Celsius for 48 seconds
UPSC perspective, the following things are important : Prelims level: Tokamak Technology, Nuclear Fusion Mains level: NA Why in the news? - South Korean scientists at the Korea Institute of Fusion Energy (KFE) achieved a significant milestone by producing temperatures of 100 million Celsius for 48 seconds in the Korea Superconducting Tokamak Advanced Research (KSTAR) fusion reactor. - KSTAR maintained the high confinement mode (H-mode) for over 100 seconds, demonstrating stability in plasma conditions crucial for sustained fusion reactions.
KSTAR maintained the high confinement mode (H-mode) for over 100 seconds, demonstrating stability in plasma conditions crucial for sustained fusion reactions. This occurs under extremely high temperatures, typically in the range of tens of millions of degrees Celsius, and pressure, similar to those found in the core of stars. In a tokamak reactor, hydrogen variants are heated to extreme temperatures to create a plasma, mimicking conditions found in the Sun’s core.
