DEMO (DEMOnstration Power Plant) is a nuclear fusion plant for energy production, designed on the basis of the experience gained from ITER and IFMIF. The device should supply the power grid with a few hundred megawatts of electric energy, demonstrate sufficient reliability and availability, and work with a closed fuel cycle. The latter means that the device must itself produce the tritium it needs. According to the schedule of the European Fusion Program, DEMO is to go online and supply power by about 2050.
