50-331 12-13-2002 Duane Arnold Energy Center Richard Woodward (319) 851-7318 Monthly Operational Overview for November 2002 At the beginning of November, the DAEC had continuously operated for 52 days since the startup following its most recent shutdown.

On November 17th between 0 1:29 and 02:07, operators briefly reduced power to 95% by withdrawing control rods and lowering recirculation flow in order to perform a load-line adjustment. On November 21, operators very slightly reduced power (approximately 2 of 1%) while the plant process computer was taken out-of-service for software maintenance.

Between November 8th and 13th, electrical power supply to modular cooling tower fans was sporadically interrupted because of high current on the electrical cabling. This caused about 0.8 full-power-hours-equivalent of lost production. A loss of approximately 9 MWe-contirnes-fromn the-tuck-ope-I lE-5B-"d htewr-Ht-r-DraiValve. This loss began October 5th and will continue until the next plant shutdown (presently scheduled for March 24, 2003).

ollowing is the allocation of production and losses:
