The NRC's blog has clarified the situation of the shutdown of Unit 2 somewhat. Apparently the damage caused by the generator stator falling, and damaging electrical equipment, led to loss of a reactor coolant pump on Unit 2 while at 100% power. This then resulted in a power to flow reactor trip (scram.) Further, within two hours after the industrial accident, water coming from a broken fire main shorted out a breaker supplying one electrical bus to Unit 2, resulting in EDG (Emergency Diesel Generator) auto-start.
