On October 1, 2011, the plant shut down so that a new reactor vessel head could be installed. During preparations for installation, FirstEnergy identified cracks in the outermost shield building, the concrete structure that protects the steel reactor containment vessel from adverse outside conditions. The U.S. Nuclear Regulatory Commission has conducted numerous inspections of the shield building and determined that the cracks do not affect the integrity of the shield building, and that the plant is safe for continued operation.
This interesting video released by the NRC takes viewers inside Davis-Besse to see the installation of the new reactor head, and includes interviews with NRC inspectors who oversaw its installation and testing, and conducted the safety reviews of the reactor shield building.http://ansnuclearcafe.org/2012/10/29/video-nrc-inspection-at-davis-besse-nuclear-power-station/
