The DEMOnstration power plant, DEMO, will be ITER's successor. With the transition from ITER to DEMO, fusion will go from a science-driven, lab-based exercise to an industry-driven and technology-driven programme. A key criterion for DEMO is the production of electricity, although not at the price and the quantities of commercial power plants.

DEMO, or a demonstration power plant (often stylized as DEMOnstration power plant), refers to a proposed class of nuclear fusion experimental reactors that are intended to demonstrate the net production of electric power from nuclear fusion. Most of the ITER partners have plans for their own DEMO-class reactors. With the possible exception of ...

Europe is planning a DEMOnstration power plant (DEMO) by 2050 as the electricity-producing machine that follows ITER. Conceptual design is progressing on this facility that aims to demonstrate the technological and economic feasibility of fusion energy, by producing about 500 MW of net electricity, as well as tritium self-sufficiency.

After ITER—the machine that will demonstrate the technological and scientific feasibility of fusion energy—DEMO will open the way to its industrial and commercial exploitation. DEMO is the machine that will bring fusion energy research to the threshold of a prototype fusion reactor.

“国际热核聚变实验堆（iter）计划”是全球规模最大、影响最深远的国际科研合作项目之一，建造约需10年，耗资50亿美元（1998年值）。iter装置是一个能产生大规模核聚变反应的超导托卡马克，俗称“人造太阳”。

iter设计目标包括实现q>10的聚变等离子体并且实现燃烧自持换句话说是"产生可观的聚变能",而 demo是欧洲建的商业聚变示范堆, 设计目标除了要在iter的基础上达到更大的q(~25),最主要的是要能保证"持续的输出电能",预期在2040年左右开始建设,参照iter的时间的话大概 ...

The Russian Federation is planning a fusion–fission hybrid facility called DEMO Fusion Neutron Source (DEMO-FNS), which will harvest fusion-produced neutrons to turn uranium into nuclear fuel and destroy radioactive waste.

俄罗斯联邦正在规划一个名为demo聚变中子源（demo-fns）的聚变-裂变混合装置，该装置将收集聚变产生的中子，将铀变成核燃料并销毁放射性废物。 DEMO-FNS计划在2023年前建成，是该国在2050年前建成核聚变电厂的快速战略的一部分。

2021年8月1日 · The short term encompasses the construction of ITER; R&D in support of ITER (which is ongoing all over the world); deuterium-tritium experiments in JET, designed to achieve and investigate ITER-like plasma regimes of operation (to start in 2021); conceptual design phase of DEMO (early designs should be ready by 2027); R&D for DEMO; and ...

What is the DEMO Design Activity? Japan and the EU both conduct design activities aimed at the construction of a fusion power reactor in their domestic fusion programmes. DEMO, a demonstration prototype, is the first step in that direction after ITER. The concepts and requirements for the EU DEMO and the JA DEMO are not the same.
