Die "reaktor" was gesmolten !
Men is achteraf, na lang beraad begonnen met zgn. "onderhoudswerken."
Het materiaal met het hoogste smeltpunt is wolfraam: 3370 °
Duizenden keren te laag om overeind te blijven bij zo'n fusie !

Nog nooit in een droge sauna van 110 °C gezeten ?
Aangenaam warm hoor.
Informeer je eens een beetje:

The temperatures inside the ITER Tokamak must reach
150 million° Celsius—or ten times the temperature at the core of the Sun—in order for the gas in the vacuum chamber to reach the plasma state and for the fusion reaction to occur. The hot plasma must then be sustained at these extreme temperatures in a controlled way in order to extract energy.
A Neutral Beam Injector and two types of high-frequency electromagnetic waves will help bring the plasma to temperatures exceeding 150 million°C.
The ITER Tokamak will rely on three sources of external heating that work in concert to provide the input heating power of 50 MW required to bring the plasma to the temperature necessary for fusion. These are neutral beam injection and two sources of high-frequency electromagnetic waves.
Ultimately, researchers hope to achieve a "burning plasma"—one in which the energy of the Helium nuclei produced by the fusion reaction is enough to maintain the temperature of the plasma. The external heating can then be strongly reduced or switched off altogether. A burning plasma in which at least 50 percent of the energy needed to drive the fusion reaction is generated internally is an essential step to reaching the goal of fusion power generation.
