French Scientists Achieve Record 22-Minute Nuclear Fusion Milestone
French scientists announced on Tuesday that they had achieved a significant breakthrough in the quest for nuclear fusion by sustaining plasma for a record 22 minutes. This milestone represents a crucial step towards harnessing clean, safe, and virtually limitless energy for the world.
Nuclear fusion involves the fusion of two atomic nuclei, mimicking the process that occurs at the core of stars. Unlike nuclear fission, which splits atoms and is used in traditional nuclear power plants, fusion has the potential to revolutionize energy production.
One of the key challenges in nuclear fusion is maintaining plasma at temperatures exceeding 100 million degrees Celsius. This hot, electrically charged gas is prone to instability, leading to energy losses and reduced efficiency.
The WEST tokamak machine in southern France achieved a significant feat by sustaining plasma for 1,337 seconds on February 12. This accomplishment surpassed the previous record set in China by 25%.

Anne-Isabelle Etienvre, the head of fundamental research at CEA, highlighted the significance of controlling plasma production and maintenance. However, she acknowledged that there are still technological barriers to overcome before achieving net energy production through thermonuclear fusion.
The WEST team is now focused on extending plasma durations and increasing temperatures to simulate conditions expected in fusion plasmas. These efforts aim to pave the way for the International Thermonuclear Experimental Reactor (ITER) in France.
ITER, a collaborative project involving several countries, has faced delays and cost overruns but remains a beacon of hope for advancing fusion research. While operational challenges have pushed the project timeline to at least 2033, the pursuit of sustainable fusion energy continues.
