Don't quite understand how a nuclear bunker is useful. MAD means you would have maybe 30 - 60 minutes to get into them? Plus, if I was attacking the country where the bunkers are located, I would make sure to blow them sky high, since I can't verify what is in them. Maybe in a pandemic they are useful, although using SARS-CoV-2 as an example, you can't be sure you aren't locking yourself up with someone carrying the virus.

Nukes don't work like that, it's not used to blow things up to the sky, it is detonated near ground to maximize it's blast zone and send the shockwave and heat as wide as possible, make an area uninhabitable.
