In 2025, China’s “artificial sun” held superheated plasma steady for 1,066 seconds, setting a new record for sustained high-confinement operation
China's EAST tokamak has made headlines by achieving a remarkable world record of 1,066 seconds of stable plasma operation. This surpasses their previous best and is a breakthrough in the quest for controlled nuclear fusion electricity production. Years of enhancements in heating and confinement technologies paved the way for this feat, with invaluable data now available for future fusion initiatives and the design of commercial reactors.
