A Key Event

"Nuclear Coma" is a event that happened before the events of the show and directly after the first game. It is referenced in season 1 episode 3: "The End Is Near!" as they prepare for a nuclear coma after this line of dialogue is said while rushing to prepare. ST: So why are we preparing? shouldn't we be continuing the nuclear core project? Dan: After the Nuclear Coma happens again the whole facility is going to blow!
