Enclosed is the monthly operating report for Peach Bottom Units 2 and 3 for the month of September 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/PRR/CSL:cmg NFA C..L Enclosures cc:

H. J. Miller, Administrator, Region I, USNRC A.C. McMurtray, USNRC, Senior Resident Inspector, PBAPS ccn 02-14072

"Peach Bottom Atomic Power Station Unit 2 September 1 through September 30, 2002 Narrative Summary of Operating Experiences Unit 2 began the month of September at 88% power, in coastdown to 2R14, with the 4 th and 5" feedwater heaters out of service.

At 2142, on September 2nd, Unit 2 reduced power to 69%, from 88%, to put the 4A and 4C feedwater heaters back in service, and remove the B string from service. Under the new configuration, the Unit returned to 88% power by 0316 on September 3 rd.

At 1500, on September 10h, the Unit 2 Turbine-Generator was tripped, and at 1505 on the same day, the reactor was manually shutdown. This was a planned operation, in support of the Unit 2, 2R14 refueling outage.

Unit 2 ended the month of September at 0% power, in mode 5 (refueling), for the 2R14 refueling outage.

Peach Bottom Atomic Power Station Unit 3 September 1 through September 30,2002 Narrative Summary of Operating Experiences Unit 3 began the month of September at 100% power.

th At 2200, on September 6t, Unit 3 reduced power to 61%, for a planned rod sequence exchange and scram time testing. The Unit returned to 100% power by 1635 on September 7 th.

At 2253 on September 8 th, Unit 3 reduced power to 93% for a planned follow-up rod pattern adjustment. The Unit returned to 100% power by 2353 on September 8 th.

At 1900 on September 2 3 rd, Unit 3 reduced power to 99%, due to the failure of a final feedwater temperature element. Following the substitution of an appropriate value in the plant computer, the Unit returned to 100% power by 0239 on September 2 4 th Unit 3 ended the month of September at 100% power.

5. Scheduled date(s) for submitting proposed licensing action and supporting information:

a.

6. Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:
a. The 2R14 reload consisted of 284 GE-14 bundles. This was the second reload of GE-14 fuel. Core verification was completed on 9/26/02.

Docket No. 50-277 Attachment to Monthly Operating Report for September 2002 Page 2 UNIT 2 REFUELING INFORMATION (Continued)

7. The number of fuel assemblies (a) in the core, (b) in the spent fuel storage pool and (c) dry storage.

(a) Core - 764 Fuel Assemblies (b) Fuel Pool - 2908 Fuel Assemblies, 58 Fuel Rods (c) Interim Spent Fuel Storage Installation - 608 fuel assemblies

8. The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies:

The spent fuel pool storage capacity has been relicensed for 3819 fuel assemblies.

9. The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present capacity:

Based on projected dry cask storage schedules and reload batch sizes, a full core discharge will remain available throughout plant life.
