I. INTRODUCTION Peach Bottom Atomic Power Station is composed of two Boiling Water Reactors and Steam Turbine/Generators located in Delta, Pennsylvania. Unit Two and Unit Three both have a Maximum Dependable Capacity of 1112 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 18, 1974, for Unit Two, and September 1, 1974, for Unit Three.

SUMMARY

OF OPERATING EXPERIENCE A. Unit TWO Unit 2 began the month of February at 100.0% of maximum allowable power (3514 MWth).

At 21:05 on February 1't, Unit 2 commenced power reduction for a planned normal plant shutdown to replace SRV 071D. The reactor was manually scrammed at 05:17 on February 2 nd. The reactor was critical at 08:23 on February 4h and the main generator synchronized to the grid at 19:56 on February 4th. The Unit returned to full power at 21:30 on February 6th.

At 23:24 on February 7h, Unit 2 reduced power to 59.2% for planned rod pattern adjustment and turbine stop valve testing. Following completion of the tests, the Unit returned to full power by 10:17 on February 9 th.

At 20:33 on February 13'h, Unit 2 reduced power to 71% for planned final rod pattern adjustment. The Unit returned to full power by 17:00 on February 14%h.

Unit 2 ended the month of February at 100% of maximum allowable power (3514 MWth).

B. Unit THREE Unit 3 began the month of February at 100% of maximum allowable power (3514 MWth).

At 16:32 on February 10h, Unit 3 reduced load to repair the A Recirc Pump EOC RPT BKR. The minimum load during the load reduction was 32% on February I Ph Following completion of the EOC RPT BKR repair the Unit returned to full power by 07:24 on February 12th.

At 02:30 on February 13 'h, Unit 3 reduced load to 69% for a rod pattern adjustment following the A Recirc Pump EOC RPT BKR replacement. Following completion of the rod pattern adjustment the Unit returned to full power by 08:23 on February 13th.

At 09:34 on February 17'h, Unit 3 reduced load to 98.7% due to loss of Core Thermal Power Calculation. Following restoration of the Core Thermal Power Calculation the Unit returned to full power by 14:42 on February 17'h.

Unit 3 ended the month of February at 100% of maximum allowable power (3514 MWth).
