Is there a prediction/paper/etc. about the mechanical loads that will be reacted onto ITER's magnetic coils?
The reason I ask is a simple calculation. My understanding of the numerical figures on ITER are that it is intended to contain;
density ~10^20
temperature ~20keV
I think that means a specific energy density of; 2e4 * 1e20 * 1.6e-19 = 320kJ/m^3
So a pressure of 320kPa.
If there is 850m^2 surface area (from https://www.sciencedirect.com/science/article/pii/S0920379610004060) then that's a total mechanical load of 272MPa (~27 atmospheres of pressure).
That is an equivalent load of 27MN on the coils on 18 toroidal coils, or 1.5MN each. That's like a 150,000 tonne load inside each coil.
I am trying to visualise hanging one of these coils and putting 5,000 fully loaded trucks inside one!
What I am thinking wrongly? Or is this right and these are mechanically very strong coils?
