The Nuclear Fusion Institute, part of Japan's Atomic Energy Research and Development Agency, recently announced the start of assembly for the JT60SA nuclear fusion experimental device. This advanced machine was developed in collaboration with the European Union and is scheduled to begin operations in 2019. The project marks a significant step forward in the global pursuit of clean, sustainable energy.
Nuclear fusion, the process that powers the sun, relies on the continuous fusion of hydrogen isotopes under extreme temperatures. When these nuclei combine to form helium and other elements, they release vast amounts of energy. If scientists can replicate this controlled reaction on Earth, it could provide a near-limitless source of electricity, revolutionizing how we power our world.
Currently, seven major international thermal fusion reactors are being built in France, involving countries such as Japan, the EU, China, the US, South Korea, Russia, and India. These projects are set to begin operations around 2020. Among them, the JT60SA plays a crucial role in supporting the development of the next-generation International Thermonuclear Experimental Reactor (ITER).
The JT60SA was largely built by upgrading the previous experimental device, JT60, incorporating new components like advanced magnetic coils designed to better confine and control plasma. Plasma, a state of matter essential for fusion reactions, must be carefully managed to sustain the high-energy conditions needed for fusion.
Compared to traditional energy sources, nuclear fusion offers a number of advantages. It uses deuterium from seawater, which is abundant and virtually inexhaustible. Unlike fossil fuels, it produces no carbon dioxide or other greenhouse gases, and its byproducts are far less radioactive than those from nuclear fission. As oil, gas, and coal reserves decline, and renewable sources like wind, solar, and bioenergy face limitations, fusion presents a promising alternative.
The ITER project was first proposed in 1985 by the Soviet Union and the United States, but faced delays due to various challenges. In recent years, growing concerns over climate change and energy security have reignited interest in the project. With renewed global focus, the dream of harnessing the power of the sun on Earth is becoming more tangible than ever.
