Peach Bottom Atomic Power Station Unit 2 March 1 through March 31,2002 Narrative Summary of Operating Experiences Unit 2 began the month of March at 100% power.

At 1158 on March 6th, Unit 2 reduced power to 99% due to the failure of a feedwater temperature sensor. The Unit returned to 100% power by 0616 on March 8'h.

At 0147 on March 2 3rd, Unit 2 reduced power to 84% for a rod pattern adjustment and main turbine stop valve testing. The Unit returned to 100% power by 0430 on March 2 3rd.

Unit 2 ended the month of March at 100% power.

Peach Bottom Atomic Power Station Unit 3 March 1 through March 31, 2002 Narrative Summary of Operating Experiences Unit 3 began the month of March at 100% power.

At 1213 on March 14 h, Unit 3 reduced power to 97% to repair a steam leak in the 3B heater drain valve. The Unit returned to 100% power by 1355 on March 1 4 th.

At 1925 on March 2 1st, Unit 3 reduced power to 74% due to an overcurrent trip on the 3B condensate pump motor. The Unit returned to approximately 82% power and stayed there for the majority of the time for this evolution. Following replacement of the damaged motor, the Unit returned to 100%

power by 0658 on March 29th.

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

Reload 14 is scheduled for September 10, 2002.

3.

Scheduled date for restart following refueling:

Restart following refueling forecast for September 30, 2002.

4.

Will refueling or resumption of operation therefore require a technical specification change or other license amendment?

Yes If answer is yes, what, in general, will these be?

a. Potential Cycle 15 Safety Limit MCPR Change.

5.

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

a. Submittal anticipated July, 2002.

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 will consist of approximately 284 GE-14 bundles. This will be the second reload of GE-14 fuel.

Docket No. 50-277 Attachment to Monthly Operating Report for March 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 - 3032 Fuel Assemblies, 58 Fuel Rods (c) Interim Spent Fuel Storage Installation - 272 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:

A full core discharge surplus of 23 licensed rack locations will remain available until the summer 2002 dry cask storage campaign. Based on projected dry cask storage schedules and reload batch sizes, a surplus of not less than 87 licensed rack locations will be available from that time, through end of plant life.
