Maybe you're right.
But I do have some good news for you. As far back as the 70s, containment buildings were supposedly designed to survive a direct hit from a loaded 747, as well as an internal explosion. I have no reason to dispute that.
The plant would, of course, be immediately put out of action, perhaps permanently, but the reactors would scram and shut down automatically and there would be no radiation release. However, no such specifications existed (at least when I was in the biz) for the buildings where the spent fuel rods and their deadly cargo of fission products are "temporarily" stored.
