OMAHA, Neb. (AP) – The Nuclear Regulatory Commission will hold another public meeting about the Omaha Public Power District’s Fort Calhoun nuclear plant this week. The event on Thursday is designed to keep the public informed about oversight of the nuclear plant 20 miles north of Omaha. The open house will be held from 11 a.m. to 2 p.m. at the Doubletree Hotel in Omaha.  The nuclear plant has been shut down since April 2011. Initially it shut down for refueling maintenance, but flooding along the Missouri River and a series of safety violations forced it to stay closed.  OPPD officials say they hope to restart Fort Calhoun in September. The utility is inspecting the plant and working to satisfy federal regulators’ concerns.
