Yes a SCRAM is an emergency shutdown, either automatic or man made. From what I just heard both reactors scrammed, and are not in power supplying mode. They are in a holding mode, but it will take a few hours to bring them back up to power.

....power restored in 10 hours or so they think.
Many reactors take days to bring up, not hours.
