France’s WEST Tokamak set a fusion record, sustaining plasma for 22 minutes, a 25% improvement, advancing long-term fusion stability.

French research organization CEA reported that on 12 February, the CEA’s WEST tokamak maintained a nuclear fusion plasma for more than 22 minutes, a 25 percent improvement over the previous record. “This leap forward demonstrates how our knowledge of plasmas and technological control of them over longer periods is becoming more

On 12 February, the CEA’s WEST machine was able to maintain a plasma for more than 22 minutes. In doing so, it smashed the previous record for plasma duration achieved with a tokamak. This leap forward demonstrates how our knowledge of plasmas and technological control of them over longer periods is becoming more mature,

Nice number, but also not much more than a nice advance France’s Commissariat à L'énergie Atomique et aux Energies Alternatives on Tuesday claimed it’s topped China’s recently-established for record maintaining fusion plasma in a tokamak,

France has taken a major leap forward in the race for nuclear fusion energy, achieving a new world record for plasma duration. On February 12, 2025, scientists at the French Alternative Energies and Atomic Energy Commission (CEA) successfully sustained a plasma reaction for 1,
