The Omaha Public Power District (OPPD) returned the single unit, 500-MW Fort Calhoun nuclear power plant to full power following a scheduled refueling outage.
During the outage, about one-third of the fuel assemblies were replaced, which will remain in the reactor for approximately four and a half years. OPPD workers also replaced the stand that holds the reactor vessel head during an outage. The stand meets recently increased seismic safety standards.
Only two workers received minor injuries during the outage. One worker cut himself while removing tape from his arm, and the other had a sore back.
Reactors typically shut down every 18 months for refueling and maintenance. The station’s next outage is scheduled for fall of 2016.
