More cracks found at nuclear power plant

FirstEnergy Corp. (NYSE: FE) said it has found additional hairline cracks in the concrete outer shell at the 913 MWe Davis-Besse nuclear power plant in Ohio.

Company officials said in Bloomberg that the cracks do not affect the facility’s structure integrity or safety and that the plant is still on schedule to return to service in late November. The single-unit plant uses a Babcock & Wilcox raised loop pressurized water reactor that has been in service since 1977.

The plant has been shut down since Oct. 1 to install a new reactor vessel head. FirstEnergy discovered another hairline crack Oct. 10 after it cut a hold in the side of the building to install the new vessel head.

The U.S. Nuclear Regulatory Commission (NRC) reportedly said it is sending a concrete expert to the plant after the previous report of cracks.

FirstEnergy is seeking a 20-year license extension for Davis-Besse from the NRC.
