WEST, a tokamak run from the CEA Cadarache site in southern France and one of the EUROfusion consortium medium size Tokamak facilities, was able to maintain a plasma for on 12 February. This was a 25% improvement on the previous record time achieved with EAST,

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,

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,

France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.
