This [0] is an F-4 hitting a concrete wall and was used to inform the design of containment walls around reactors.

Would there be some shitty days for people and things outside the containment wall? You bet! But there wouldn't be any shitty nuclear days. In fact, I suspect radioactivity release would be worse with a coal plant crash as it would release the nasty stuff that we do manage to scrub out of the exhaust.
