ITER is one of the most ambitious scientific projects in the world. It is being built in the south of France and involves the cooperation of 35 countries, including the European Union, the United States, China, India, Japan, Russia, and South Korea. The goal of ITER is to show that nuclear fusion can be used as a safe and powerful source of clean energy.
Nuclear fusion is the process that powers the sun and stars. It happens when two light atoms, like hydrogen, join together to form a heavier atom. When this happens, a huge amount of energy is released. Unlike nuclear fission, which is used in current nuclear power plants, fusion does not produce dangerous radioactive waste or risk of explosion. It also uses fuel that can be made from seawater, which means it could provide almost unlimited energy for the future.
The ITER reactor is a giant machine called a tokamak. It is shaped like a doughnut and uses strong magnetic fields to hold extremely hot plasma inside. The plasma can reach temperatures of over 150 million degrees Celsius, about ten times hotter than the center of the sun. Scientists will try to keep this plasma stable long enough to produce more energy than is needed to heat it.
When ITER begins operation in the 2030s, it will not generate electricity yet, but it will be a major step toward future fusion power plants. The success of ITER could change the world's energy future by giving us a clean, safe, and almost endless energy source. This international project shows how countries can work together to solve global challenges for the good of all humanity.
