Color me skeptical.Actually none of this would be possible. Nuclear power plants have higher security than most military bases.
I recall a case where protesters, one of them a nun, managed to come to a nuclear weapons plant's wall and bang on it with hammers for half an hour, and only after that they were arrested. Googgling...
Aw, I'm wrong. Not half an hour. "They were able to spend more than two hours inside the restricted area before they were caught".
