Peach Bottom Atomic Power Station Unit 2 October 1 through October 31, 2002 Narrative Summary of Operating Experiences Unit 2 began the month of October at 0% power, in mode 5 (refueling), for the 2R14 refueling outage.
At 1315, on October 2 nd, the Unit 2 reactor was declared critical.
At 0706, on October 3 rd, Unit 2 was synchronized with the grid. By 2200 that evening, the Unit was at 30% power. By 0019 on October 5', the Unit was at 56% power. At 1305, on October 5th, Unit 2 reached 100% power.
At 1624 on October 5 h,Unit 2 reduced power 79%, due to a high oil level alarm on the 2B recirc pump motor. Following troubleshooting, the Unit returned to 100% power by 0111 on October 6'.
At 1640 on October 6', Unit 2 reduced power to 95.4% in a planned load drop to complete the core flow measurement test, RT-I-002-250. Following completion of the test, at 0149 on October 7 h,the Unit reduced power further to 74.6%, in a planned rod pattern adjustment. The Unit returned to 99%
power by 0804 on October 7'.
From this point until 1320 on October 16 t', Unit 2 was administratively held at 99% power, while an investigation was conducted into unexpectedly high electrical output following return to full power post-2R14. Following completion of the investigation, on October 16th, at 1320, Unit 2 again reached 100% power.
At 2200 on October 18d, Unit 2 reduced power to 48% in an unplanned load drop (planned more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in advance) to walkdown the moisture separator area, and inspect leaks on the Caldon LEFM spool pieces. Following completion of the walkdown, the Unit returned to 100% power by 0912 on October 19th.
At 2255 on October 20th, Unit 2 reduced power to 95% for a follow-up rod pattern adjustment. The Unit returned to 100% power by 2338 on October 2 0 th.
At 0136 on October 27th, Unit 2 reduced power to 95% in a planned load drop for turbine stop valve testing. The Unit returned to 100% power by 0318 on October 2 7th.
Unit 2 ended the month of October at 100% power.
Peach Bottom Atomic Power Station Unit 3 October 1 through October 31, 2002 Narrative Summary of Operating Experiences Unit 3 began the month of October at 100% power.
Unit 3 operated at 100% power for the entire month of October.
Unit 3 ended the month of October at 100% power.
