SUMMARY

The reactor remained at approximately 100% power from February 1, 2002 to February 9, 2002. Plant power was reduced on February 9, 2002 at 1705 hours0.0197 days <br />0.474 hours <br />0.00282 weeks <br />6.487525e-4 months <br /> from approximately 100 percent power to approximately 95 percent power to maintain a control rod index less than 297 after a RCS boron increase occurred when placing deborating demin #1 in service. Plant power was returned to approximately 100 percent power on February 11, 2002 at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br />.

OPERATING DATA REPORT DOCKET NO. 50-0346 UNIT NAME Davis-Besse Unit 1 DATE 03/02/02 COMPLETED BY A.S. Quaderer TELEPHONE 419-321-7384 REPORTING PERIOD February, 2002 YEAR TO MONTH DATE CUMULATIVE 1 Design Electrical Rating (MWe-Net). 906 The nominal net electrical output of the unit specified by the utility and used for the purpose of plant design.

2 Maximum Dependable Capacity (MWe-Net). 882 The gross electrical output as measured at the output terminals of the turbine generator during the most restrictive seasonal conditions minus the normal station service loads.

3 Number of Hours the Reactor Was Critical. 363.6 1,107.6 147,634.3 The total number of hours during the gross hours of the reporting period that the reactor was critical.

4 Number of Hours the Generator Was On Line. 362.9 1,082.2 145,037.1 (Also called Service Hours). The total number of hours during the gross hours of the reporting period that the unit operated with breakers closed to the station bus.

The sum of the hours the generator was on line plus the total outage hours should equal the gross hours in the reporting period.

5 Unit Reserve Shutdown Hours. 0.0 0.0 5,532.0 The total number of hours during the gross hours of the reporting period that the unit was removed from service for economic or similar reasons but was available for operation.

6 Net Electrical Energy (MWH). 305,977 923,533 119,112,148 The gross electrical output of the unit measured at the output terminals of the turbine-generator minus the normal station service loads during the gross hours of the reporting period, expressed in mega watt hours. Negative quantities should not be used.
