Yes, in 1999 (when I last toured the plant) the SCRAM time was 3.5 seconds with control rods fully placed in 0.5 seconds if the emergency circuit is tripped. This happens automatically in the event of a 6.0 or stronger quake. An emergency SCRAM requires 30 to 120 days to restart the reactor. Also like all reactors, it requires time to cool. Because DCNP is located on the ocean it does not require active cooling to safely cool the reactor core after a crash. flooding the core with sea water will probably be the end of that reactor, but it will not loose containment. The plant was originally designed to be operational after a 7.0 quake and to not loose containment in the event of a 9.5. After the discovery of the Hsgri fault the design was modified to withstand a 10.8 quake. Analysis after the 2004 6.2 quake in Paso Rubles suggests that the engineering was "very conservative" and that the plant may well be able to survive an 8.0 in operational condition.
On the other hand, the temporary on site storage of spent fuel was not part of the original plan, In the event of a major seismic event, it is the spent fuel casks that scare me.
