That’s true Forces in ITER are very big
But this means nothing. We are talking about the system increasing its temperature on about 20 deg even in case of the worst scenario. Field in Alcator C-mod and projected Italian-Russian Ignitor Tokamak are here: correspondently on-axis toroidal field in ITER 5-6T vs. 8 and 13T for Alcator and Ignitor. The last two have resistive and not superconducting magnets. Also in 80s of last century there was a project of Ignitex with 20T of TF (toroidal field) and also with resistive single turn coil.
Why I have asked about teapot with whistling valve? One safety valve would solve the problem of overpressure in the cooling loop. Do not worry.
I note you about the real problem of TOKAMAK. The problem you are worrying is farfetched.
By the way what do you think, what type of cooling system is used for superconducting magnets? Opened loop of closed?
PS: lithium in breeding modules is Li6 or Li7 and if I recall correctly both isotopes are not radioactive.
