"The Union of Concerned Scientists is questioning whether the building housing the Davis-Besse nuclear reactor was properly designed and remains structurally sound. The challenge comes about three weeks after contractors cutting a hole in the building to replace the reactor's lid noticed a long hairline crack on one side of the opening."

"In a letter to the Nuclear Regulatory Commission, the watchdog group has asked whether engineering specifications for the building's concrete walls were adequate to begin with. "
