There is no event report yet. They should have filed within 8 hours so I'm guessing that the NRC web site hasn't updated yet (since it is now approaching 10 hours). The NRC spokesman noted: "It appears this was an uncomplicated, smooth shutdown," so it wasn't a scram (they didn't fear that reactor safeguards had been compromised to the point where it wasn't safe to perform a shutdown versus a scram)--therefore it was probably a minor instrument or if it was a major instrument their redundant instruments were working.

Basically, from my experience operating nuclear reactors (in the Navy) this means that there wasn't an issue in safely operating the reactor, but if one or more further instruments failed that they would have to scram. Sort of a minor issue here and not worthy of the notice of the AP. Read the recent event reports and you will find tons of events more serious than this in the last 2 weeks. This event is only getting attention because it involves the TMI plant.

I did computer support at a nuclear power plant for 7 years. What I learned is the hardest thing about running a nuclear plant is keeping it running - they are designed so that any small deviance shuts the thing down automatically for safety's sake.
