Enclosed is the monthly operating report for Peach Bottom Units 2 and 3 for the month of October 2003 forwarded pursuant to Technical Specification 5.6.4 under the guidance of Regulatory Guide 10.1, Revision 4.

Sincerely, Garey L. Stathes Director, Site Engineering Peach Bottom Atomic Power Station GLS/PRR/CSL:cmg q(R-C!&L Enclosures cc:

Peach Bottom Atomic Power Station Unit 2 October 1 through October 31, 2003 Narrative Summary of Operating Experiences Unit 2 began the month of October at 98.6% power (3458 MWth), with the Caldon LEFM feedwater flow measurement system out of service.

At 1530 on October I", Unit 2 increased power to 3496 MWth, following analysis and resolution of the problems with the Caldon LEFM feedwater flow measurement system. This power level (3496 MWth) will now be the maximum allowable for the Unit until repairs are made to the Caldon system in the 2R1 5 refueling outage next fall.

At 2300 on October 3rd, Unit 2 reduced power to 59% for a planned rod pattern adjustment. The Unit returned to maximum allowable CTP (3496 MWth) by 0100 on October 5th.

At 2310 on October 25th, Unit 2 reduced power to 93% for planned testing of the turbine stop valves and intermediate valves. The Unit returned to maximum allowable CTP (3496 MWth) by 0200 on October 26&h.

At 1748 on October 28h, Unit 2 reduced power to 3458 MWth (approximately 98.6%) due to the failure of a feedwater temperature sensor. With the temperature sensor out of service, the Unit was restricted to 3458 MWth. Following replacement of the failed sensor, the Unit returned to 3496 MWth by 0700 on October 30'h.

Unit 2 ended the month of October at its new maximum allowable Core Thermal Power level of 3496 MWth (from this point forward referred to as 100% CTP).

Peach Bottom Atomic Power Station Unit 3 October 1 through October 31, 2003 Narrative Summary of Operating Experiences Unit 3 began the month of October at 0% power, in mode 5, in the 3R14 refueling outage.

At 0635 on October 1 1', Unit 3 was declared critical. At 0400 on October 13 &, the Unit was synchronized with the grid. During the ascension to full power coming out of the refueling outage, the 3A recirc pump came in with a high seal cavity temperature alarm, and the Unit reduced power to 60% for investigation. Following successful investigation and testing, the Unit reached 100%

allowable CTP (3458 MWth) by 0700 on October 17'h.

At 0700 on October 17'h, Unit 3 reduced power to 76%, as part of the planned work to implement the Appendix "K" uprate from 3458 MWth to 3514 MWth. By 2300 on October 18'h, the Unit had reached its new maximum allowable CTP of 3514 MWth, which will be referred to as 100% CTP from this point forward.

Unit 3 ended the month of October at its new 100% power level of 3514 MWth.
