The DAEC operated at full thermal power throughout the month except:
* February 7 - 8, to perform scheduled turbine control valve surveillance testing and a control rod sequence exchange,0.9 full-power-hours lost.
* February 9 - 10, to perform maintenance on the "A" Recirculation Pump Motor-Generator Set.14.1 full-power-hours lost.
* February 11 - 27, to maintain margin to thermal limits,14.9 full-power-hours lost.
Total forgone production (including other small planned losses) was the equivalent of 32.0 full-power hours of operation.
At the end of the month the Duane Arnold Energy Center had operated 269 consecutive days, its best-ever continuous operating run.
