Factual error: Near the end of the movie, when the heroine is attempting to disable the nuclear aspect of the bomb, she spends a lot of time trying to remove one of the high explosive segments form the core, when simply cutting as many of the detonator wires as possible would seem to have accomplished the same thing. A nuclear detonation requires simultaneous detonation of all the explosive segments to cause the core to go critical. Even a small delay, caused by one or more segment not going off at precisely the right time would have resulted in only a non-nuclear explosion, which is what happened.
