Z-day... not so much

My husband works at a nuclear power plant. Yes, he is Homer Simpson, stfu. We were just discussing nuclear reactors and both realized that their very existence causes the whole "Zombie Apocalypse" scenario to fall apart. Think about it. For whatever reason most of the population has been wiped out or zombified. The handful of survivors that remain are too busy surviving to be like "Hey, the power is out pretty much everywhere. Perhaps I had better get my ass to the nearest nuclear power plant and monitor the reactor so it doesn't go critical."
So really, about a week after the world turns into a zombie smorgasbord, it won't even matter, because the whole planet is going to go kablooey anyway.
Problem solved.
