Power officials made efforts on Wednesday (local time) to bring two nuclear reactors back on line in southern Florida, one day after a massive blackout shut them off & darkened millions of homes across the state but the reactors still are not running. The disabled reactors at the Turkey Point nuclear power plant were unlikely to cause new blackouts but workers labored feverishly to get them operating again.

Tuesday’s monster power outage left millions of people in southern Florida bereft of electricity for several hours. A substation snafu is being blamed for leaving three million people without power in various parts of Florida on Tuesday afternoon.

A minor glitch in Florida’s electrical grid triggered a chain reaction that caused a nuclear plant to shut down but they but don’t know how the glitch happened. Power was briefly cut in patches from Daytona Beach to the Florida Keys. An official said that the most of the outages were caused by bad weather, not the grid problems.
