World's Largest Experimental Nuclear Fusion Reactor Begins Operations in Japan

The JT-60SA, a joint project between the European Union and Japan, is seen as a stepping stone to the International Thermonuclear Experimental Reactor (ITER) in Europe.

The JT-60SA, the world's largest experimental nuclear fusion reactor, has officially started operations in Japan. The reactor is a joint project between the European Union and Japan.
The reactor uses a 'tokamak' design, a toroidal chamber with magnetic coils, to heat plasma to 200 million degrees Celsius, mimicking the energy production process of the sun.
The JT-60SA is seen as a stepping stone to the International Thermonuclear Experimental Reactor (ITER) in Europe, which is still under construction and has faced financial and logistical challenges.
Although nuclear fusion has the potential to provide a sustainable, emission-free energy source, it currently operates at a net energy loss. However, experts believe that with further technological advancements, fusion reactors could achieve net energy production gains.
Another method of achieving nuclear fusion, inertial confinement fusion, has shown promise at the National Ignition Facility in the United States, where a net energy gain was achieved earlier this year.
