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 January at 84.2% of maximum allowable power (3514 MWth). The Unit returned to full power by 13:58 on January "t.
nd At 09:33 on January 2, Unit 2 reduced power to 62.5% for a rod pattern adjustment from the December 28, 2004 2A condensate pump trip. The Unit returned to full power by 18:02 on January 3 d.
At 23:26 on January 4th, Unit 2 reduced power to 66.7% for planned turbine stop valve testing. Following completion of the tests, the Unit returned to full power by 03:45 on January 6Oh.
At 22:47 on January 9h, Unit 2 reduced power to 99% due to unexpected change in core flow (unexpected change in recirc pump speed). The Unit returned to full power by 11:56 on January 10h.
At 00:00 on January 22nd, Unit 2 reduced power to 78.2% due to lowering intake canal level and lower condenser vacuum due to icing at the outer intake structure.
The Unit returned to full power by 20:55 on January 22nd.
Unit 2 ended the month of January at 100% of maximum allowable power (3514 MWth).
Correction to the December report: The December report identified a load reduction at 20:58 on December 28th Unit 2 reduced power to 62.5% due to a 2A Condensate Pump trip. This event should have read as follows; at 20:58 on December 28h Unit 2 reduced power to 71.1% due to a 2A Condensate Pump trip.

SUMMARY
OF OPERATING EXPERIENCE B. UnitTHREE Unit 3 began the month of January at 100% of maximum allowable power (3514 MWth).
At 22:03 on January 11'h, Unit 3 reduced load to 95.3% for planned HCU Maintenance. Following completion of the HCU maintenance the Unit returned to full power by 23:30 on January 11th.
At 23:00 on January 14"', Unit 3 reduced load to 47.6% for a planned rod sequence exchange. Following completion of the rod sequence exchange the Unit returned to full power by 19:15 on January 15'h.
At 23:16 on January 16'h, Unit 3 reduced load to 83.7% for a planned final rod pattern adjustment. Following completion of the rod pattern adjustment the Unit returned to full power by 01:32 on January 17'h.
At 21:36 on January 23 rd, Unit 3 reduced load to 93% due to lowering intake canal level and lower condenser vacuum due to icing at the outer intake structure. The Unit returned to full power by 10:29 on January 24 Unit 3 ended the month of January at 100% of maximum allowable power (3514 MWth).
