Superman is just figuring out his powers.
He gets punched in the face by Biff Tannen, and Biff breaks his hand.
Do you think this should make Superman feel safe going up against an AK-47? A tank? A bomb?
All we knew, is that if he takes a train to the face (blunt force), then he can rebuild himself.
We also knew that when he hit his head on impact, his mind was wiped.
He should have had no reason to believe that he can just casually brush off a nuke with the reconstruction mechanism. There was no reason to believe it wouldn't be destroyed too, until it was tested.
