I. INTRODUCTION Peach Bottom Atomic Power Station is composed of two Boiling Water Reactors and Steam TurbineiGenerators located in Delta, Pennsylvania. Unit Two and Unit Three both have a Maximum Dependable Capacity of 1 1 12 MWe Net. The Station is jointly owned by Exelon Nuclear and Public Service Electric and Gas. The Nuclear Steam Supply Systems are General Electric Company Boiling Water Reactors. The Architect/Engineer and Primary Construction Contractor was Bechtel Corporation. The Susquehanna River is the condenser cooling water source. The plant is subject to license numbers DPR-44 and DPR-56, issued October 25, 1973, and July 2, 1974, for Unit Two and Unit Three respectively, pursuant to Docket Numbers 50-277 and 50-278. The dates of initial Reactor criticality for Units Two and Three were September 16, 1973, and August 7, 1974, respectively. Commercial generation of power began on February 1 8, 1974, for Unit Two, and September I, 1974, for Unit Three.

SUMMARY
OF OPERATING EXPERIENCE A. UnitTWO Unit 2 began the month of October at 0% power, in the 2R15 refueling outage.
At 0636 on October 7h, Unit 2 was declared critical, following the successful completion of the 2R15 refueling outage.
At 03 15 on October 9Ih, Unit 2s generator was synchronized with the grid.
At approx. 2 100 on October 1 Oth, during power ascension out of 2R15, Unit 2 reduced power to 8 1 %,
due to a lube oil leak on the C reactor feedpump. The C feedpump was taken out of service, and the Unit returned to approx. 93% power, which is the maximum allowable with only two out of thee feedpumps in service.
During the period when the Unit was operating with two out of three feedpumps in service, at approx.
2303 on October 1 I h, the Unit reduced power to 76%, for a planned rod pattern adjustment, to set the final rod pattern. The Unit returned to 93% power by 01 55 on October 1 Zth.
At 01 20 on October 1 3h, following completion of repairs to the C reactor feedpump, the Unit reduced power %om 93% to 80%, in order to bring the C feedpump back in service. With the C feedpump in service, the Unit reached 98.4% (3458 MWth) power by 08 17 on October 1 3h.
At 11 55 on October 14Ih, Unit 2 reached its maximum core thermal power of 3514 MWth, with the commissioning of the Caldon LEFM feedwater flow measurement system.
At 1330 on October 1 6Ih, Unit 2 reduced power to 89%, in response to a high oil level alarm in the 2B reactor recirculation pump. Following repairs, the Unit reached full power (35 14 MWth) by 01 I 1 on October 1 gth.
At 2300 on October 2 1 I, Unit 2 reduced power to 57%, for power suppression testing, following the determination that chemistry parameters indicated the existence of a leaking fuel assembly. After the leaking assembly was blocked, the Unit returned to full power by 1425 on October 26h.
At 2300 on October 27h, Unit 2 reduced power to 79%, for a planned follow-up rod pattern adjustment.
The Unit returned to full power by 1626 on October 28Ih.
Unit 2 ended the month of October at 100% of maximum allowable power (3514 MWth).
- 3. UnitTHREE Unit 3 began the month of October at 100% of maximum allowable power (35 14 MWth).
Unit 3 remained at 100% power for the entire month of October.
Unit 3 ended the month of October at 100% of maximum allowable power (3514 MWth).
