Fusion power generation (fusion reactor) is also called 'artificial sun' and is being researched all over the world to solve energy shortages and switch to renewable energy. In December 2020, South Korea's fusion research device ' KSTAR ' succeeded in maintaining a plasma of 100 million degrees for 20 seconds.

According to China's

Xinhuanet , EAST also succeeded in maintaining a plasma of 100 million degrees for 20 seconds in 2020. After that, about 300 researchers and engineers upgraded the vacuum system, laser scattering system, microwave system, etc. And on May 28, 2021, EAST succeeded in maintaining a plasma of 120 million degrees for 101 seconds, breaking the world record.

According to the Xinhuanet, EAST is operated with the ultimate goal of providing energy by performing nuclear fusion using

heavy water existing in seawater. EAST estimates that deuterium contained in 1 liter of seawater can produce energy equivalent to 300 liters of gasoline.

The research results of EAST will also be used for the international fusion experimental reactor 'ITER ' in which 35 countries including Japan participate in the development. In addition, the ' JT-60SA Project ' jointly implemented by Japan and Europe and the research results of KSTAR are scheduled to be fed back to ITER, and expectations are rising for the realization of fusion power generation.
