I bet that last is a SCRAM switch of some kind: "Press in case of imminent Armageddon" to drop all control rods fully into the reactor core, cut power and trigger a Halon dump in the server room, or some other expensive but disaster-averting sequence of events. Still, to label it "Armageddon" instead of "Fire" or "Meltdown" or just "Emergency" takes a certain sense of humour.
