Enclosed is the monthly operating report for Peach Bottom Units 2 and 3 for the month of April 2003 forwarded pursuant to Technical Specification 5.6.4 under the guidance of Regulatory Guide 10.1, Revision 4.
Sincerely, Carey 1. Stathes Director, Site Engineering Peach Bottom Atomic Power Station GLS/PRR/CSL:cmg A& CS-Enclosures cc:

Peach Bottom Atomic Power Station Unit 2 May through May 31, 2003 Narrative Summar, of Operating Experiences Unit 2 began the month of May at 80% power.
At approx. 2300 on April 30th, Unit 2 began a series of load drops for the purpose of power suppression testing. At 0023 on May 1', Unit 2 was at 77% power, and by 0140, it was at 63%
power. At 0520, power suppression testing commenced. At 1300 on May 3rd, fuel bundle 30-23 was identified as the source of the fuel leak.
Slightly after 1300 on May 3rd, Unit 2 reduced power from approximately 60% to 30% to facilitate repairs to the Caldon LEFM system, and to complete condenser waterbox cleaning. At 0031 on May 4th, the Caldon repair was completed. At 0045 on May 4h, condenser waterbox cleaning was complete. By 0300 on May 4h, the Unit was at 44% power. At 1324 on May 4h, it had reached 56%
power, and by 1204 on May 5th, it had reached approximately 7Q% power. Power ascension was slower than normal due to limitations imposed by the failed fuel operating procedures.
By 1200 on May 6th, Unit 2 had returned to approximately 85% power. At 1505 on May 6th, power was briefly reduced from 85% to 80%, due to oscillations in the #3 main turbine control valve.
At 0015 on May 7h, Unit 2 commenced a rod pattern adjustment, during which troubleshooting was conducted on the #3 control valve. At 0419, with the rod pattern adjustment completed, power ascension resumed. By 0622 on May 8", Unit 2 was at 71% power. At 1558, the oscillations in the
- 3 control valve reappeared, and power was reduced to 65%. Repairs were completed on the #3 control valve at 1452 on May 9, and power ascension resumed. The Unit reached 100% power by 2100 on May 11l.
At 1100 on May 12h, a load drop to set the final rod pattern adjustment was started, and the Unit reduced power to 55% power by 1330. When the rod pattern adjustment was completed, the Unit once again resumed power ascension. The Unit reached 100% power by 1420 on May 14th.
Unit 2 ended the month of May at 100% power.
Peach Bottom Atomic Power Station Unit 3 May through May 31, 2003 Narrative Summary of Operating Experiences Unit 3 began the month of May at 100% power.
At 2300 on May 16", Unit 3 reduced power to 52%, for condenser waterbox cleaning and maintenance work on the reactor feedpump turbines. By 0841, on May 17h, the work was complete, and power ascension had begun. The Unit returned to 100% power by 0216 on May 18"l.
At 0124 on May 19', a follow-up rod pattern adjustment was begun, and the Unit reduced power to 85%. Following completion of the rod pattern adjustment, the Unit returned to 100% power by 0537 on May 19"'.
Unit 3 ended the month of May at 100% power.
