DEMO

DEMO ( Demonstration Power Plant ) could be the successor to the under construction experimental nuclear fusion reactor ITER. DEMO would serve the development and testing of technologies, physical operating areas and control algorithms and is a so-called " closed fuel cycle ", ie, the breeding of the currently required tritium in the blanket of the reactor demonstrate. As a demonstration power plant DEMO would contain all the components to generate electricity and feed it at 2-4 GW fusion power at the earliest from 2040 or 2050, 1 to 1.5 gigawatts into the grid. Commercial fusion power plants, in the last quarter of this century would have to be larger to work economically ..

Currently DEMO is more a buzzword for the acquisition of funding as a specific project. According to one approach, the actual planning and construction of DEMO to about 10 years would plasma research with ITER support, which should start in 2020. Another approach (K- DEMO) is in favor of a beginning of the design phase already in 2022 by then still unconfirmed, but more conservative assumptions for the achievable parameters. Also, is not yet certain whether a permanently burning plasma is economically possible with the Tokamak principle; DEMO could also be a successor of the stellarator Wendelstein 7 -X.
