OMAHA, Neb. (AP) — Operators say the Fort Calhoun nuclear power plant is about halfway through several studies, changes and inspections that have been ordered before the plant can resume operation.

A public meeting with Nuclear Regulatory Commission officials in Omaha on Tuesday, plant manager Mike Prospero said a lot of work remains before the Omaha Public Power District presses the NRC for a restart.

Prospero says “that will not happen until we are convinced we can restart safely and operate reliably for a long time in the future.”

Fort Calhoun, which sits about 20 miles north of Omaha, has been offline since April 2011. It was initially shut down for refueling maintenance, but flooding along the Missouri River and safety violations forced it to remain offline.
