JT-60SA is the largest and most advanced nuclear fusion reactor in the world.
It started operations in Ibaraki Prefecture of Japan on 01 December.
It is a joint initiative between the European Union and Japan. It is the world’s biggest experimental nuclear fusion reactor.
Fusion differs from fission. Fission is the technique currently used in nuclear power plants.
Fusion includes fusing two atomic nuclei in place of splitting one nucleus.
The six-story-tall JT-60SA reactor is kept in a hangar near Naka north of Tokyo. Hangar is a large building where planes are kept.
It consists of a “tokamak” vessel in the shape of a doughnut that is intended to hold spinning plasma that has been heated to 200 million degrees Celsius.
JT-60SA is a forerunner for the under-construction International Thermonuclear Experimental Reactor (ITER).
The goal of both JT-60SA and ITER is to induce the fusion of hydrogen nuclei into helium, a heavier element, releasing energy in the form of heat and light.
