Enclosed is the monthly operating report for Peach Bottom Units 2 and 3 for the month of July 2002 forwarded pursuant to Technical Specification 5.6.4 under the guidance of Regulatory Guide 10.1, Revision 4.
Sincerely, Paul J. Davison Director, Site Engineering Peach Bottom Atomic Power Station PJD/PRRICSL:cmg f e!st Enclosures cc:

Peach Bottom Atomic Power Station Unit 2 August 1 through August 31, 2002 Narrative Summary of Operating Experiences Unit 2 began the month of August at 100% power.
At 2310, on August 3rd, Unit 2 reduced power to 93%, from 98.7%, to remove the 4th feedwater heaters from service. With the 4th heaters out of service, the Unit was able to return to 100% power at 0203, on August 4th.
At 0200, on August 31 s, Unit 2 reduced power to 73%, from 90.7%, to support putting the 4t' stage feedwater heaters back in service, to be followed by removing the entire "B" string from service.
During the evolution, the 4C feedwater heater extraction steam stop valve would not open, so the evolution was aborted, with the 4' and 5' heaters still out of service. The Unit returned to 88%
power by 2314, on August 21St.
Unit 2 ended the month of August at 88% power, in coastdown to 2R14, with the 4t1h and 5th1 feedwater heaters out of service.
Peach Bottom Atomic Power Station Unit 3 August 1 through August 31, 2002 Narrative Summary of Operating Experiences Unit 3 began the month of August at 100% power.
At 1122, on August 3 0th, Unit 3 reduced power to 90%, in anticipation of the shutdown of the 3A circ pump, due to high circ water screen differential pressure. The high screen dP's were caused by a sudden surge in the amount of fish (Gizzard Shad) that entered the intake canal. Following circ pump inlet screen cleaning, the Unit returned to 100% power by 1345 on August 3 0 1h.
Unit 3 ended the month of August at 100% power.
