JAEA gets us one step closer to positive fusion

The Japan Atomic Energy Agency (JAEA) just announced that its JT-60 Fusion Tokamak reactor nearly doubled the world record of tokamak plasma from 16.5 seconds to 28.6 seconds.  Nuclear physicists propose that once tokamak reactors can achieve approximately 400 seconds of plasma, the reactor will achieve a stable, sustainable nuclear fusion reaction.

The JT-60 tokamak is one of the largest tokamak reactors in operation today, and was the same reactor that set the previous fusion confinement time of 16.5 seconds.  The previous world record for plasma duration stood for two years.
