(FPL.N) 580-megawatt Duane Arnold nuclear power station in Iowa ramped up to 96 percent power by early Monday, the U.S. Nuclear Regulatory Commission said in a report.
On Friday, the unit was operating at 17 percent of capacity as it exited a refueling outage.
The unit started to exit the outage on March 3 but operators stopped the restart before the plant attached to the grid after identifying higher than normal temperatures on a turbine bearing.
It started to exit the outage again on March 4.
The unit shut on Feb. 1 due to the loss of condenser cooling as it was coasting down for the refueling outage.
It last shut for refueling from about Feb. 4-March 18, 2007 and is on a 24-month refueling cycle.
Duane Arnold, which entered service in 1975, is located in Palo in Linn County, about 125 miles east-northeast of Des Moines, Iowa's capital.
It’s an antique, and stupidly designed. In the modern world everybody knows you build with multiple piles hooked up to multiple turbines and have them setup in flowing mode.
