OMAHA, Neb. (AP) — The Nebraska nuclear plant that has been idle for nearly three years because of flooding and a series of safety concerns has been cleared to restart. The federal Nuclear Regulatory Commission said Tuesday that the Omaha Public Power District’s Fort Calhoun nuclear plant is safe to restart. Fort Calhoun, which sits across from Iowa on the Missouri River about 20 miles north of Omaha, has been offline since April 2011.

Fort Calhoun initially shut down for routine maintenance, but significant flooding in 2011, a small fire and a number of violations forced it to remain closed.
