Sorry to break a myth, but you'll never hear someone about “THE RED BUTTON ” in a nuclear control room. There's way too much buttons that happens to be red for that.

Nuclear operators are highly trained professionals (two years of training in France, for instance) who know their machine by heart, so what you'll hear will be much more specific like “isolate vapor generator number 3”. Also, the way it's organized it will very rarely be orders, but instead description if what each of them are doing while following the safety procedure, to keep other crew members aware of what they're doing.

So no “Press that god damn red button!” but instead “I'm bypassing turbine through GCTA and moving to step 342.B.3”.
