Q

ITER is of key importance in the roadmap, particularly as it aims to prove the scientific and technological of fusion as a future energy source. Although ITER itself will not produce electricity, - the device that may follow - should already model a real future fusion power plant and produce electricity. This in turn will pave the way for future commercialisation and use of fusion power, possibly when?.

ITER is of key importance in the roadmap, particularly as it aims to prove the scientific and technological feasibility of fusion as a future energy source. Although ITER itself will not produce electricity, DEMO - the device that may follow - should already model a real future fusion power plant and produce electricity. This in turn will pave the way for future commercialisation and use of fusion power, possibly in the second half of the century.

Q

By participating in ITER, the EU makes substantial investment in European industry. More than €x billion has already been invested in this way, which has had a strong and positive impact on the European economy in terms of producing economic growth and boosting employment. A study on the impact of ITER, and other fusion projects within the Broader Approach, on the EU economy further showed that ITER generated a net impact worth €x million in 2008-2019.

By participating in ITER, the EU makes substantial investment in European industry. More than €4 billion has already been invested in this way, which has had a strong and positive impact on the European economy in terms of producing economic growth and boosting employment. A study on the impact of ITER, and other fusion projects within the Broader Approach, on the EU economy further showed that ITER generated a net impact worth €104 million in 2008-2019.

Q

ITER will be the largest tokamak in the world; approximately x meters high and x meters wide, weighing 23,000/2,300/230 tonnes. As an experimental device, it is not designed to produce electricity. It will, however, pave the way towards a demonstration fusion power plant in the second half of this century, which will produce electricity and serve as a precursor to commercial fusion power production.

ITER new base line: The 2016 Baseline envisioned achieving First Plasma in x, as a brief, low-energy machine test, with relatively minimal scientific value, to be followed by four stages of assembly and construction, achieving full plasma current in x. The new baseline envisions the x (SRO) in x, featuring a more complete machine, to be followed by 27 months of substantive research. The achievement of will be about x years delayed from the previous baseline, from 2033, now targeted in x. Deuterium-x fusion operation is targeted for 2035, about the same time as in the previous baseline.
