- DEMO abstract "DEMO (DEMOnstration Power Plant) is a proposed nuclear fusion power plant that is intended to build upon the expected success of the ITER experimental nuclear fusion reactor. The objectives of DEMO are usually understood to lie somewhere between those of ITER and a "first of a kind" commercial station. While there is no clear international consensus on exact parameters or scope, the following parameters are often used as a baseline for design studies: Whereas ITER's goal is to produce 500 megawatts of fusion power (a source of heat) for at least 500 seconds, the goal of DEMO will be to produce at least four times that much fusion power on a continual basis. Moreover, while ITER's goal is to produce 10 times as much power as is required for breakeven, DEMO's goal is to produce 25 times as much power. DEMO's 2 to 4 gigawatts of thermal output will be on the scale of a modern electric power plant. Also, DEMO is notably intended to be the first fusion reactor to generate electrical power. Earlier experiments, such as ITER, merely dissipate the thermal power they produce into the atmosphere as steam.To achieve its goals, DEMO must have linear dimensions about15% larger than ITER and a plasma density about 30% greater than ITER. As a prototype commercial fusion reactor, DEMO could make fusion energy available by 2033. Subsequent commercial fusion reactors could be built for nearly a quarter of the cost of DEMO if things go according to plan.While fusion reactors like ITER and DEMO will produce neither transuranic nor fission product wastes, which together make up the bulk of the nuclear wastes produced by fission reactors, some of the components of the ITER and DEMO reactors will become radioactive due to neutrons impinging upon them. It is hoped that plasma facing materials will be developed so that wastes produced in this way will have much shorter half lives than the waste from fission reactors, with wastes remaining harmful for less than one century.[citation needed] Development of these materials is the prime purpose of the International Fusion Materials Irradiation Facility. The process of manufacturing tritium currently produces long-lived waste, but both ITER and DEMO will produce their own tritium, dispensing with the fission reactor currently used for this purpose.PROTO is a beyond DEMO experiment, part of European Commission long-term strategy for research of fusion energy. PROTO would act as a prototype power station, taking in any remaining technology refinements, and demonstrating electricity generation on a commercial basis. It is only expected after DEMO, meaning a post-2050 timeline, and may or may not be a second part of DEMO/PROTO experiment. This might possibly make PROTO the first commercial nuclear fusion power plant in the world.".
