OMAHA, Neb. (AP) — A Nebraska nuclear plant is operating at full power again after its second brief outage in the past three months, utility officials said Wednesday.
The Omaha Public Power District said Fort Calhoun resumed generating electricity on March 19 — two days after a problem on the non-nuclear side of the plant during maintenance triggered the shutdown.
The nuclear plant that sits along the Missouri River across from Iowa about 20 miles north of Omaha reached full power again on March 21.
This is the second time Fort Calhoun went offline briefly since it restarted in December after a prolonged outage.
In January, Fort Calhoun had to stop generating power for four days because ice built up on one of six gates the plant uses to control water from the Missouri River and kept it from closing.
Before that, Fort Calhoun had been shut down for nearly three years. It initially shut down in April 2011 for routine maintenance, but significant flooding in 2011, a small fire and a series of safety violations forced it to remain closed until December.
OPPD spokesman Jeff Hanson said the latest shutdown happened when workers were performing maintenance on the generator on March 17.
The generator lost coolant during the work. Hanson said that triggered the automatic shutdown of the turbine and then the reactor because there was no need to produce steam when the generator wasn't operational.
