This is just crazy. Yet more anti-nuclear spin on a non-event. The unit is turned off because of loss or risk of loss of off site power. Pure and simply, nothing to see here, move along, kind of stuff. You see coal fired plants shutdown when they create too much heat, or the steam powered turbines spin too fast (which by the way can happen to just about every power plant type out there since almost all designs use them, nuclear, gas, coal, oil, high temp thermo, molten salt solar, etc). These things happen all the time. Yet, somehow everyone goes crazy when it happens at a nuclear plant.
What gets me even more is that the slant that is put on these stories (sometimes even by /. itself). This isn't a safety problem. It is safety protocol. This is like screaming that metal detectors don't help at security checkpoints because you now see an increase in people with weapons compared to when you didn't have metal detectors, so obviously the addition of metal detectors caused that increase in people with weapons at that location...
