The power failure in Florida today has generated stories anywhere from the failure of nuclear reactors causing the outage, to the main power generator failing.

Currently it seems the story of a main power generator failure is the true story. As far as the nuclear reactors, they are in good shape at this time.

A spokesman for the Florida Power & Light company initially said, "the Turkey Point plant south of Miami caused the outages to about a fifth of Florida's population. But the utility's nuclear spokesman, Dick Winn, later said grid problems caused both reactors at the plant to shut down between 1 p.m. and 1:30 p.m.

"All the safety systems worked just like they were supposed to and both of those units are in stable condition right now," he added.

As mentioned here, "It seems at this time the number of people impacted by the power failure was around 800,000. The larger numbers of over 4 million were probably assumed because Florida Power & Light serves that many people within the particular grids, but not necessarily experiencing the failure."

 
Nuclear Reactors Automatically Shut Down

Power was already restored in some places by early afternoon and was estimated to be fully restored by 6 p.m., said Florida Power & Light, the state's largest utility.

The Nuclear Regulatory Commission said the two reactors automatically shut down. Two other power plants farther north, the Crystal River reactor and St. Lucie twin reactors, continued to operate, although officials at those two facilities noticed the grid disturbance.

Nuclear Power Plants Respond as they're designed to do

Bob Coleman, FPL’s Daytona Beach-based regional manager of external affairs, said the substation outage caused the shutdown of a pair of nuclear power plants, as they were designed to do when their sensors detected fluctuations in the grid nearby. That caused major feeder circuits to trip to protect the distribution grid.

"The system worked the way it’s designed," Coleman said. "If we lose two major power plants, like we did, the feeder circuits are tripped to stabilize the system."

Failure of Power Lines cause Nuclear Reactor shut down

The reactors shut down because of the failure of power lines at a substation in the region, the US Nuclear Regulatory Commission said.

"Our latest information is that two power lines went out at a substation somewhere between Miami and Daytona" in southern Florida, said commission spokesman Daniel McIntyre.

"An under-voltage resulting from that caused the shutdown of the nuclear reactors at Turkey Point," a plant operated by FPL, he said, as mass power cuts were reported across the south of the state.

Authorities said there were no safety concerns.
