I’m not disagreeing with you, but one of the major issues you mention seems to be moving huge amounts of air in order to cool and dehumidify deep underground.
Why not use more efficient technologies to accomplish this, like heat pumps? Dehumidification systems exist also. You’d still need air flow of course for breathing, but that would be significantly less than is needed for everything else you described.
It would be expensive and complex vs a hole with a fan, sure, but we’re talking about building fancy ultra expensive secret nuclear facilities anyway, and if the added cost can make it impervious or at least very resistant to missile attack, the added cost seems worth it.
Maybe you could have a liquid-cooled or even a phase-chane heat exchanger, but I don’t know if that’s even possible. Maybe it is. Maybe someone, somewhere has done it before? Would be interesting to look into.

If you draw that in paint we will have gone full circle.
You also make it much more obvious the deeper you go which is sorta not awesome for sites that are intended to be secret.
