Fusion: South Korean KSTAR reactor hits 100 million degrees Celsius for 30 seconds

It is becoming a habit: at the very end of 2020, the South Korean fusion reactor KSTAR had reached 100 million degrees Celsius for 20 seconds, which was then the world record for the duration of these extreme temperatures. Rebelote therefore a year later, this time with 100 million degrees Celsius obtained for 30 seconds! This is a scientific achievement, but it is no longer a record: indeed, last June, the Chinese reactor EAST had reached 120 million degrees for 101 seconds!

The KSTAR experimental reactor (Korea Superconducting Tokamak Advanced Research) continues to improve from test to test, and makes more and more credible the promise of a new energy source that is both inexhaustible, with an almost zero carbon footprint and above all capable of handling the rapid growth of human energy needs for centuries to come.

The engineers in charge of KSTAR now hope to hold 100 million degrees for 300 seconds, by 2026. The rapid progression of the results is something to be rather optimistic: in 2018, KSTAR reached 100 million degrees Celsius for 1.5 seconds “barely”!
