Because the energy required to spin up the main generator(s) is by itself huge. A large power plant (of any sort, not just nuclear) requires a substantial fraction of their own output power to run cooling pumps, control systems, and the like. Also, there's the issue of spooling up whatever generator is used, which is generally done by feeding power from the grid back into the station. In a so called black start situation, some generating stations on the grid have diesel generators that can be started by a big bank of batteries or compressed air. Those are used to bootstrap that plant, which is in turn used to start other plants, and so on. Since this station tripped during the earthquake, it's only source of power was from the generators on site.
Interesting.
Thanks for clearly describing the issues in a well thought out and lucid response.
Nicely done.
