Duane Arnold Energy Center Docket No: 50-331 Operating License: DPR-49 February 2002 Monthly Operating Report File:
A-118d Please find enclosed the Duane Arnold Energy Center Monthly Operating Report for February 2002. The report has been prepared in accordance with the guidelines of NRC Generic Letter 97-02: Revised Contents Of The Monthly Operating Report, and distribution has been made in accordance with DAEC Technical Specifications, Section 5.6.4.
The November 2001, December 2001, and January 2002 Monthly Operating Reports' "AVERAGE DAILY UNT POWER LEVEL" pages incorrectly reported power level for the 28t" day of ea6h of those months. (The formula had been revised October 28t' for the Daylight Savings to Standard time change, then not changed back.) Revised pages are included with this report.
Very truly yours, Rob Anders5"on' Plant Managei--Nuclear!.

(319) 851-7318 Monthly Operational Overview for February 2002 The DAEC operated at its 1770 MWth administrative thermal power limit throughout the month except for one brief power reduction to perform a load-line adjustment. At 00:40 on February 24' reactor power was lowered to 1713 MW,,h by inserting control rods to reduce load-line. Reactor Recirculation System flow was increased to raise power to 1770 MWI, at 01:18.
At 12:00 on February 3rd drywell unidentified leakage was observed to be increasing. This was the re-continuation of a trend first observed January 4 th through 12"' when unidentified leakage had increased from 0.05 GPM to 0.24 GPM. During this time, consultations with the load-dispatcher had established a tentative early March plant shutdown date to identify and repair the source of the leakage. However, leakage returned to 0.05 GPM January 17'. The DAEC Technical Specification Limit for drywell leakage is 5 GPM unidentified, 25 GPM total, and 2 GPM increase within previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
At 04:00 February 4"', unidentified drywell leakage increased again to 0.25 GPM, and then continued increasing. On February 17" leakage had surpassed 1.00 GPM. Chemical analysis of a drywell floor drain sample indicated the leakage source is well water, which is used in the drywell air coolers. The sample contained poly-phosphates (indicating well-water),
but no Sodium-24 (which would indicate reactor coolant). Leakage continued sporadically increasing, to 1.25 GPM February 20"', to 1.83 GPM on the 2 2no, to 2.18 GPM at 14:02 on the 25t', then on the 26"' dropped and held steady at approximately 0.8 - 0.9 GPM through the end of the month. (The scheduled shutdown to identify and repair the source of the leakage occurred when the generator was taken off-line at 02:05 March 4%.)
At the end of February, the DAEC had continuously operated 128 days since its most recent shutdown.
