OAK HARBOR -- The Davis-Besse Nuclear Power Plant has returned to service.
The plant shut down on May 6 for scheduled refueling and maintenance. According to FirstEnergy Nuclear Operation Company, the plant began producing energy around 3:37 a.m. It's currently at 30-percent power and is expected to reach full power later this week.
According to FirstEnergy, during the shutdown, inspections of the station's Shield Building revealed that tight cracks in the building's wall found in 2011 had not grown and no new cracks were discovered.
Last week, technicians discovered and repaired a small leak in a vent line discovered when the plant was powering up. The pinhole allowed some radioactive coolant water to leak out into a containment area but the Nuclear Regulatory Commission agreed with the company that there was never any hazard to the public health.
