France breaks world record for plasma duration with WEST tokamak

France's WEST tokamak sets a new record, maintaining stable plasma for more than 22 minutes, a crucial step towards nuclear fusion.
Nuevo récord de plasma estable durante 22 minutos

On February 12, the CEA-operated WEST (Westinghouse Tokamak) facility in southern France achieved a milestone in the field of nuclear energy. The device managed to maintain a stable plasma for 22 minutes and 17 seconds, beating China’s previous plasma record by 25% . This breakthrough represents a technological achievement and opens new doors towards plasma stabilization in future fusion reactors such as ITER .

Is France close to dominating the plasma record?

With an injection of 2 MW of thermal power, WEST managed to maintain the plasma at 50 million degrees Celsius , far exceeding previous records. This breakthrough is part of global efforts to achieve a clean and sustainable source of energy through nuclear fusion . Despite the advances, the process remains a challenge due to the inherent instability of the plasma.

France is positioning itself as a leader in nuclear fusion research, thanks to the CEA and its super-advanced facilities like WEST . Researchers hope that this breakthrough will allow for much longer plasma lifetimes and even higher temperatures, approaching the conditions needed for ITER, the next big step in fusion energy .
