PHILADELPHIA (CBS) – Exelon, the parent company of PECO, says one of its two reactors at the Limerick nuclear power plant has shutdown.

According to the power company, the number two reactor automatically shutdown after an electrical problem in one of the turbines that generates power.

In a news release, the company says there is no risk to the public and no one at the plant was injured by the shutdown.

It says operators are investigating the cause of the shutdown and working to restore the reactor to service.

Exelon says the other reactor at the plant about 21 miles north of Philadelphia continues to operate at full power.
