They often keep that shit in tanks outside, particularly depleted(figuring out what to do with depleted uranium hexafluoride is often a challenge and the US has a truly staggering amount of full tanks just sitting around waiting to leak). Once it hits air you get hydrofluoric acid gas which will spread thanks to the explosion and will kill you in small concentrations(as low as 30 ppm). It’s awful and blowing it up to spread it everywhere is even more awful. The only thing worse would be bombing a purex plutonium reprocessing plant. That is just as toxic in different ways but you can make the tanks go prompt critical thanks to changing it’s geometry and it has actual fission products you can spread around. Those reprocessing plants were a main plank in how north Korea got their bomb.
I guess I’m a train now.
