The International Thermonuclear Experimental Reactor (better known a ITER) is a massive nuclear fusion research project in Provence, France. Funded by the EU, China, India, Japan, Russia, South Korea and the US, it is projected to lead to the world’s biggest magnetic containment plasma physics reactor, and possibly to a breakthrough in nuclear fusion energy production. Nuclear fusion uses two isotopes of hydrogen, deuterium and tritium, in a reaction that produces large amounts of energy, helium, and virtually no carbon dioxide, radioactive waste or other problematic pollutants or by-products. In July 2020 the assembly stage of ITER was official launched, following over three decades of planning and site construction, but there remains controversy around this technology with differing opinions on its timescale, feasibility, and safety. Will nuclear fusion be the answer to humanities energy needs that traditional nuclear fission has failed to be? Does nuclear fusion hold more promise than other forms of sustainable energy production? Can such a bold project even be achieved by such confrontational nations as are involved in the project?
