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, Director, Site Engineering Peach Bottom Atomic Power Station GLS/Pl3lVCSL:cmg Enclosures cc:

Peach Bottom Atomic Power Station Unit 2 April 1 through April 30, 2003 Narrative Summary of Operating Experiences Unit 2 began the month of April at 100% power.

At 1847, on April 12k', Unit 2 automatically scrammed on high reactor pressure, due to an air line break on an outboard MSIV. This caused the MSIV to fail closed. Following repairs, the Unit was declared critical at 2259 on April 13 'h, and the turbine-generator was synchronized with the grid at 1150 on April 14th. The unit reached 3458 MWth (max rated without Caldon LEFM operable) at 0603 on April 15th. Following investigation and resolution of minor LEFM system anomalies, Unit 2 reached 3505 MWth (max rated with LEFM operable) by 2300 on April 16h.

At 2300 on April 3&, Unit 2 began a load drop to at first 60% power, and finally 30% power for power suppression testing, to identify a leaking fuel assembly. By 0000 on May 1I, the Unit had reduced power to approximately 80% rated. The Unit will return to 100% power in May, following completion of power suppression activities.

Unit 2 ended the month of April at 80% power.

Peach Bottom Atomic Power Station Unit 3 April 1 through April 30, 2003 Narrative Summary of Operating Experiences Unit 3 began the month of April at 100% power.

At 0920 on April 3 rd, Unit 3 reduced power by 5 MWe, for the planned installation of new Final Feedwater Temperature measurement software (AFTO). The Unit returned to 100% power by 1819 on April 3 rd At 2323 on April 16'h, Unit 3 reduced power to 88%, for HCU maintenance activities. The Unit returned to 100% power by 0230 on April 176'.

At 2320 on April 17th, Unit 3 reduced power to 87%, for follow-up scram timing of rods following maintenance on April 16h - 17'h. The Unit returned to 100% power by 0300 on April 18th.

Unit 3 ended the month of April at 100% power.
