Chinese fusion reactor sets world record

Posted by in categories: nuclear energy, physics, sustainability

China has announced a milestone in the development of clean, sustainable energy by setting a new world record for the longest duration of temperatures needed for fusion to occur.

The Experimental Advanced Superconducting Tokamak (EAST) located in Hefei, Anhui Province, is the successor to HT-7, China’s first superconducting tokamak, which retired in 2013. The Hefei Institutes of Physical Science (HIPS) is conducting the experiment for the Chinese Academy of Sciences (CAS).

Professor Gong Xianzu, a researcher at the CAS Institute of Plasma Physics (IPP) who is leading the project, announced the breakthrough. The reactor achieved not one but two milestones. Firstly it reached a plasma temperature of 120 million degrees Celsius for 101 seconds. This is 20% hotter and five times longer than last year, when EAST managed 100 million degrees Celsius for 20 seconds. Secondly, it reached an even higher peak temperature of 160 million degrees Celsius, lasting for 20 seconds.
