Peach Bottom Atomic Power Station Unit 2 February 1 through February 28, 2003 Narrative Summary of Operating Experiences Unit 2 began the month of February at 100% power (3505 MWt).

At 0648, on February 17th, Unit 2 decreased power to 37%, as a result of the trip of the 2B recirc pump MG set. Following troubleshooting and repairs, the Unit returned to 100% power by 1729 on February 20th.

At 0230 on February 2 1St, Unit 2 reduced power to 91% for a follow-up rod pattern adjustment. The Unit returned to 100% power by 1230 on February 21st.

At 2300 on February 2 1St, Unit 2 reduced power to 85% for a second follow-up rod pattern adjustment. The Unit returned to 100% power by 0556 on February 2 2nd.

Unit 2 ended the month of February at 100% power (3505 MWth).

Peach Bottom Atomic Power Station Unit 3 February 1 through February 28, 2003 Narrative Summary of Operating Experiences Unit 3 began the month of February at 100% power.

At 0734 on February 9th, Unit 3 reduced power by 5 MWe (roughly 15 MWth, 99.5% CTP) during swap over of the 3D Monicore to the backup computer. The Unit returned to 100% power by 1840 on February 9 th.

th At 2210 on February 14, Unit 3 reduced power to 75% for a planned rod pattern adjustment. The Unit returned to 100% power by 0529 on February 15th.
