SUMMARY

OF UNIT 1 OPERATING EXPERIENCE July 1986 7/1 Unit 1 began this reporting period at full reactor power (825 MWe).

7/10 At 2055, Unit 1 reduced power to 720 MWe when No. 12 Circulating Water Pump was secured.

The pump had to be secured when shear pins on No. 12 A&B Traveling Screens failed, causing high differential pressure.

7/15 At 2300, Unit.1 began reducing power to 700 MWe for Condenser Water Box cleaning.

7/16 At 1028, Unit 1 returned to full power (825 MWe).

7/20 At 0500, Unit 1 tripped because a failed surge capacitor caused No. 12B Reactor Coolant Pump (RCP) to trip.

7/21 At 1835, the Unit became critical, and the breaker was shut at 2054.

7/21 At 2230, the Unit stopped increasing power due to a 30%

chemistry hold.

7/22 At 0430, the chemistry hold was removed and the Unit was at full reactor power (825 MWe) by 1300.

7/26 At 0230, power was reduced to 700 MWe for Condenser Water Box cleaning.

At 1230, power was increased to 815 MWe so Moderator Temperature Coefficient (MTC) testing could be performed.

7/29 At 2125, MTC testing was completed and the Unit was returned to full power (825 MWe).

7/31 The Unit was at full reactor power (825 MWe) at the end of this reporting period.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE July 1986 7/1 Unit 2 began this reporting period at full reactor power (825 MWe).

7/7 At 1940, Unit 2 reduced power to 495 MWe because of a tripped transformer at Waugh Chapel.

7/8 At 0150, the transformer was back in service and Unit 2 began increasing power.

At 0530, Unit 2 was at full reactor power (825 MWe).

7/25 At 1345, commenced shutdown of Unit 2 due to unidentified Reactor Coolant System (RCS) leakage greater than 1 GPM.

7/25 At 1536, the breaker was opened.

At 1617, the reactor was shut down.

The leakage was found to be due to a failed flexible hose on a seal pressure transmitter.

The Unit remained in a shutdown condition to investigate high vibration on #21B RCP.

7/31 Unit 2 was shutdown at the end of this reporting period.
