Operators of China’s HT-7U reactor, known as EAST (Experimental Advanced Superconducting Tokamak), have claimed a new fusion record, representing an incremental step in the long road to commercial energy production.
According to the official Xinhua news agency, the EAST reactor was able to maintain stable plasma at high temperatures for 1,056 seconds (17.6 minutes). That represents a significant improvement above the previous record of 101 seconds set last year. EAST operates on deuterium, a stable hydrogen isotope abundant in nature.
