France’s Nuclear Reactor Maintains 90 Million°F Plasma for a Record-Breaking 22 Minutes, 17 Seconds — A Major Fusion Milestone France has achieved a historic breakthrough in nuclear fusion research by sustaining plasma at nearly 90 million°F (50 million°C) for an unprecedented 22 minutes and 17 seconds. The achievement was recorded at the WEST Tokamak, operated by the French Alternative Energies and Atomic Energy Commission (CEA), marking a critical step toward practical fusion energy. Fusion re

40 Million Degrees Celsius: Germany’s Largest Fusion Reactor Sets New World Record The world’s most powerful stellarator, Wendelstein 7-X, has raised the so-called triple product to a record level during long plasma discharge times — a key benchmark in the global race toward nuclear fusion. The reactor near Greifswald achieved plasma durations of over 43 seconds with temperatures reaching up to 40 million degrees Celsius — more than twice as hot as the center of our Sun. A crucial factor in this
