Demonstration fusion plants: A stepping stone to large-scale, commercial electricity production (Arabic Edition)

The aim of ITER, the world's largest fusion experiment, is to prove how to create net energy from a fusion reaction. Demonstrating that net electricity can be produced from fusion energy will then be the next significant step. This is where demonstration fusion power plants, or DEMOs, will come in. DEMO-type reactors are more of a design concept than a particular fusion machine configuration. Preliminary designs for publicly funded DEMOs, under development in several countries, are yet to be finalized. This will be done following results of the ITER experiments. DEMOs are planned to operate almost continuously to produce more than 50 megawatts (MW) of net electrical gain. The key challenge they will set out to address is how to keep the fusion plasma stable for long enough to produce energy on an ongoing basis.
