France sets fusion record with 22-minute plasma stability, beats China’s nuclear run | WEST sustained hydrogen plasma for over 20 minutes using 2 MW heating, marking a key milestone as experiments move to higher power.
France’s WEST Tokamak set a fusion record, sustaining plasma for 22 minutes, a 25% improvement, advancing long-term fusion stability.
According to CEA, the ultimate objective is to manage the inherently unstable plasma while ensuring that any component that comes into contact with it can tolerate its radiation without breaking down or contaminating it. “WEST has achieved a new key technological milestone by maintaining hydrogen plasma for more than twenty minutes through the injection of 2 MW of heating power. Nuclear fusion aims to control inherently unstable plasma, offering a highly efficient energy source with minimal fuel use and no long-lived radioactive waste.
