China's "Artificial Sun" Reactor Sets New Fusion Record, Powering Clean Energy Race
9 Oct, 2025
Summary
- China's EAST fusion reactor sets new world record for steady-state, long-pulse H-mode plasma operations
- Reactor achieved temperatures over 100 million degrees Celsius for 17 minutes and 46 seconds
- Milestone marks significant progress in fusion research, moving from basic science to engineering practice
As of October 9th, 2025, China's Experimental Advanced Superconducting Tokamak (EAST) fusion reactor has achieved a significant milestone in the race for clean, sustainable energy. EAST, often referred to as China's "artificial sun", has set a new world record by sustaining a high-temperature plasma for 17 minutes and 46 seconds.
The reactor successfully maintained "steady-state, long-pulse H-mode plasma operations" at a temperature exceeding 100 million degrees Celsius (180 million degrees Fahrenheit). This breakthrough represents a major step forward in fusion technology, as achieving such high temperatures and long durations is crucial for the development of viable fusion reactors.
Experts say this milestone marks a turning point in fusion research, transitioning from basic scientific exploration to practical engineering applications. "This achievement not only verifies the feasibility of steady-state operation for fusion reactors but also marks a major turning point in fusion research from basic scientific exploration to engineering practice," the researchers stated.
If China can continue to push the boundaries of fusion technology, a fully operational fusion reactor could be closer than previously thought. Fusion power holds the promise of providing massive amounts of clean, affordable energy without the drawbacks of traditional nuclear fission or fossil fuels, making it a key to a sustainable energy future.
