Peach Bottom Atomic Power Station Unit 2 December 1 through December 31, 2002 Narrative Summary of Operating Experiences Unit 2 began the month of December at 100% power.
At 1047, on December 17th, Unit 2 reduced power to 91%, for planned TIP run, to support LPRM gain calibration activities. The Unit returned to 100% power by 1243 on December 17th.
At 2303 on December 17 th, Unit 2 reduced power to 16% for planned activities to repair leaks in the Caldon LEFM flow measurement system. Following completion of the repairs, and a follow-up rod pattern adjustment, the Unit returned to 100% power by 1510 on December 21 st.
At 2035 on December 2 1 st, Unit 2 automatically scrammed due to a malfunctioning EHC control system card. Following troubleshooting and repairs, the Unit reached critical operation at 0030 on December 24 h, and was synchronized with the grid at 1531 on December 2 4th. The Unit reached th 100% power by 0604 on December 25 At 1152 on December 2 5 th, Unit 2 reduced power to 90% for a follow-up rod pattern adjustment.
th The Unit returned to 100% power by 1252 on December 25 At 2300 on December 2 9th, Unit 2 reduced power to 85% for a planned rod pattern adjustment. The Unit returned to 100% power by 0211 on December 3 0th.
At 1104 on December 30 th, Unit 2 reduced power to 99.6%, to end oscillations of the #3 turbine control valve. During this same period, investigations commenced concerning uncertainties in the Caldon LEFM flow measurement system. At 2128 on December 3 1st, the Caldon LEFM system was declared inoperable and was removed from service, pending further investigations. With the Caldon LEFM system out-of-service, the Unit was de-rated to 98.4% power, which was its previous rating of 3458 MWth.
Unit 2 ended the month of December at 98.4% power (3458 MWth).
Peach Bottom Atomic Power Station Unit 3 December 1 through December 31, 2002 Narrative Summary of Operating Experiences Unit 3 began the month of December at 100% power.
Unit 3 remained at 100% power for the entire month of December.
Unit 3 ended the month of December at 100% power.
