The Oyster Creek Nuclear Generating Station automatically shut down when thunderstorms knocked out power to the area at 1:35 a.m. on July 12, and the plant declared an "unusual event" - the lowest level of alert - 15 minutes later.
The all clear was sounded after electrical power was restored to the area at 4:05 a.m., but the plant remained off-line the following day for equipment testing. No word was given on when it might be put back into service.
The plant got a new 20-year license in April. It will be 60 years old at the end of the license.
