DOCKET NO.: 50-331 DATE: 02-14-2003 Unit: Duane Arnold Energy Center COMPLETED BY: Richard Woodward TELEPHONE: (319) 851-7318 Monthly Operational Overview for January 2003 At the beginning of January, the DAEC had continuously operated for 113 days.

The following departures from full thermal power (1790 MWth) production occurred during the month:

"* brief(< 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months ) power reductions January 5ta, 19t", 20'h and 24"' to 1700 MWth for control rod movements to adjust load-line

"* a six-hour thirty-five minute reduction to 1750 MWth on January 15th to calibrate the feedwater flow transmitter and reset the feedwater correction factor

"* a twenty-five-hour fifty-five-minute reduction to 1145 MWth on January 18th to (a) perform turbine valve testing, (b) to temporarily remove the 'B'_cooling tower from service to valve-in the temporary modularscoolingtowers, and (c) to perform a sequence exchange.

At 22:42 on January 31st, the INFLUENT HIGH CONDUCTIVITY annunciator activated and the Abnormal Operating Procedure for Reactor Water / Condensate High Conductivity was entered at 23:09 when hotwell conductivity reached 0.13 iimho. At 00:18 and 00:19 on February 1', the CONDENSER HOTWELL HIGH CONDUCTIVITY and RWCU HIGH CONDUCTIVITY annunciators activated. At 00:23 a reduction in Reactor Recirculation System Flow to 27 million lb/hour was commenced. At 00:54 hotwell conductivity had risen to 10.8 pmho, and an orderly shutdown had commenced. At 02:26, the '1AI' and 'IA2' essential 4160KV power supplies were transferred from the Auxiliary Transformer to the Startup Transformer. At 02:33, with power at 1000 MWth, a manual scram was initiated.

(Narrative of shutdown and forced outage will continue in the February monthly report.)
