SUMMARY

OF UNIT 1 OPERATING EXPERIENCE AUGUST 1986 8/1 Unit 1 began this reporting period at full reactor power (825 MWe).

8/3 At 0815, Unit 1 began reducing power to 680 MWe for Condenser Water Box cleaning.

4 8/3 At 2030, Unit 1 returned to full power (825 MWe).

8/6 At 2115,, Unit 1 began reducing power to 630 MWe for Condenser Water Box cleaning.

8/7 At 0700, Unit 1 returned to full power (825 MWe).

8/11 At 2235, Unit 1 began reducing power to 690 MWe to clean

. Condenser Water Boxes.

8/12 At 0650, Unit 1 returned to full reactor power (825 MWe).

8/12 At 2200, Unit 1 began reducing power to'700 MWe to clean Condenser Water Boxes.

8/15 At 0330, Unit 1 returned to full reactor power (825 MWe).

8/23 At 1522, Unit 1 began reducing power to 705 MWe for Condenser Water Box cleaning.

8/24 At 0430, Unit 1 returned to full power (825 MWe).

8/27 At 2130, Unit 1 began reducing power to 730 MWe for Condenser Water Box cleaning.

8/28 At 0545, Unit-1 returned to full power (825 MWe).

8/31 Unit 1 ended this reporting period at full reactor power (825 MWe).

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE AUGUST 1986 8/1 Unit 2 was shutdown at the start of this reporting period because of suspected excessive vibration of 21A Reactor Coolant Pump.

8/1 At 0500, Unit 2 was critical.

8/1 At 2043, the Unit was paralleled.

Subsequent power ramp up was slowed because of poor water chemistry.

8/2 At 0700, reactor power was held at 682 MWe so STP-M-213-2 could be performed.

8/2 At 2100, the Unit was returned to full power 825 MWe, 8/21 At 1740, reactor power was reduced to 750 MWe because of a failure of Screen Wash Header piping.

8/22 At 0200, Unit 2 returned to full power 825 MWe.

8/31 At 1125, reactor power was reduced to 785 MWe because of a damaged guide bearing on 24 Circulating Water Pump.

8/31 The Unit was at 95% reactor power (800 MWe) at the end of this reporting period.

5.

Scheduled date(s) for submitting proposed licensing action and supporting information.

September 29,1986 6.

Important licensing considerations associated with the refueling.

Reload fuel will be similar to that reload fuel inserted into the previous cycle.

7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool.

(a) 217 (b) 998*

Spent Fuel Pools are common to Units 1 and 2 8.
