South Korean Scientists Smash Nuclear Fusion Record

Physicists in South Korea managed to keep high-performance plasma stable for 70 seconds this week. This gives the Korean Superconducting Tokamak Advanced Research (KSTAR) reactor the record for the longest ever time sustaining such reaction. [Image Source: Michael Maccagnan/Wikipedia ] This superheated plasma holds the key to unlocking nuclear fusion for virtually limitless and reliable energy. The Daejeon-based institute said they used a high-power neutral beam to contain the plasma. “The world record for high-performance plasma for more than a minute demonstrated that the KSTAR is the forefront in steady-state plasma operation technology in a superconducting device,” National Fusion Research Institute said in a statement . “This is a huge step forward for realization of the fusion reactor.” The KSTAR reactor is a tokamak reactor, one in which heated plasma blobs can reach up to 300 million degrees Celsius. Magnetic fields hold these blobs together, fusing hydrogen atoms to […]
