Wieviel Effizienz wird vom I.T.E.R. erwartet ?

JET's Real Numbers
In 2014, while I was working on a book, one of my editors encouraged me to get better information on the progress in fusion research since the 1950s. Dean and Schaffer had already told me that the actual efficiency of the JET reactor wasn't 65 percent and that the number was not based on all electricity consumed by the reactor. But what was the real power consumption? What was the real progress in reactor power over the years? Dean suggested that I contact JET directly. Nick Holloway, the media manager for the Communications Group of the Culham Centre for Fusion Energy, which operates the JET fusion reactor, responded promptly and clearly to my inquiry.
The full electrical input power consumed by the JET reactor, Holloway told me, was at least 700 million Watts (megawatts, or MW) of electricity. Therefore, with a heat output of 16 MW, JET came only within 2 percent (rather than 65 percent) of producing power at a rate equal to the rate of power it consumed. The 2 percent number is based on a less-conservative of two calculation methods, comparing the heat output rate to the electrical input rate.
[glow=red,2,300]A more conservative calculation method normalizes the heat power output to electrical power, using a 40 percent conversion efficiency, and gives a reactor power efficiency of less than 1 percent.[/glow]

Dean and Schaffer explained to me why fusion scientists, among themselves, never talk about the full electrical power requirements of fusion reactors: From their perspective, it's irrelevant.
That's not fusion scientists' current objective.
A reactor that can produce power at a rate greater than is consumed by the reactor isn't expected until the latter part of this century.
I.T.E.R. also kein Kraftwerk sondern eine reine Forschungseinrichtung.
