The perenial "Nuclear Power Plant" example

The nuclear power plant thing is a pet peeve of mine.
Could someone please explain exactly which systems in a nuclear power plant require something to happen within a few microseconds? I only ask because I would think that in any good design, the necessity of that level of response would not be necessary. I don't know about you, but I would be hard pressed to replace a piece of hardware in the event of hardware failure in a few microseconds. It would take me at *least* several milliseconds, if not more.
Are we really sitting on the edge of armageddon, awaiting,in silent terror, the time that some system fails to respond (for any reason) within a microsecond or two?
I sincerely hope that the above is a reducto al absurdum.
Otherwise, I would say that "The End Is Nigh".
