OAK HARBOR, Ohio (AP) - Operators of a northern Ohio nuclear plant that sits along Lake Erie say workers there found a gap within the concrete of a protective wall.
Officials at the Davis-Besse nuclear plant near Toledo describe the gap as an air pocket and say they don't believe it affected the structural integrity of the shield wall.
The gap was discovered Thursday while the plant was shut down to replace two steam generators.
A spokeswoman for the Nuclear Regulatory Commission tells The Blade newspaper in Toledo that it's too early to say whether the gap was a problem.
The NRC now plans to send more inspectors to the plant operated by Akron-based FirstEnergy Corp.
FirstEnergy says the gap runs along a cut made in 2011 when a new reactor head was installed.
