SUMMARY
OF UNIT 1 OPERATING EXPERIENCE AUGUST 1985
/
8/1 At the beginning of this reporting period, Unit I was shut down continuing its seventh scheduled refueling outage.
8/5 No.11D Reactor Coolant Pump shaft seal replacement was complete and the reactor was taken critical at 1406.
8/6 The Unit was paralleled at 0405. At 0426, the reactor tripped on loss of load when the main turbine tripped on high levelin 11 Moisture Separator Reheater. The Unit was brought critical at 0922 and paralleled at 1350.
The main turbine was removed from the grid at 1804 for planned maintenance and paralleled at 2120. At 2146, the reactor tripped on low steam generator level.
l 8/7 The reactor was brought critical at 0318 and paralleled at 0547. At 1950, i
the reactor tripped on loss of load when the thrust bearing wear sensor erroneously tripped the main turbine.
J 8/8 The reactor was brought critical at 0615 and paralleled at 0935.
+
8/14 Commenced shutting down the Unit at 1700 to investigate high temperatures in the main generator stator. The Unit was removed from the grid at 2024 and the reactor shut down at 2030.
1 8/27 A stator coolant flow problem was corrected and the Unit was brought critical at 0830.
8/28 The Unit was paralleled at 0553.
8/29 The Unit was brought to 100% power (820 MWe) at 1045.
8/31 At the end of this reporting period, Unit 1 was operating at 830 MWe with i
the reactor at 100% power.
i
SUtdMARY OF UNIT 2 OPERA'I1NG EXPERIENCE AUGU8T 1985 8/1 At the beginning of this reporting period, Unit 2 was shut down continuing a planned outage while repairs were being made to 21 Main Steam Isolation Valve hydraulic system.
8/5 The reactor was brought critical at 0623 and paralleled at 1006.
8/6 The Unit was brought to fullload operation (825 MWe) at 0400.
8/13 Reduced load to 630 MWe at 2205 to clean main condenser waterboxes.
8/14 Resumed fullload operation (800 MWe) at 0910. Reduced load to 790 MWe at 1747 when two condenser air removal units tripped.
Resumed full load operation (800 MWe) at 1810.
8/17 Reduced load to 600 MWe at 0400 to clean main condenser waterboxes.
8/19 Load was increased to 700 MWe at 0700, but 100% power could not be reached due to high circulating water differential temperature. Reduced load to 570 MWe at 2225 to clean waterboxes.
8/20 Resumed full load operation (813 MWe) at 0745. Reduced load to 630 MWe at 2200 to clean main condenser waterboxes.
8/21 Resumed full load operation (815 MWe) at 0930.
8/23 Reduced load to 620 MWe at 2155 to clean main condenser waterboxes.
8/24 Resumed full load operation (840 MWe) at 1415.
8/26 Reduced load to 640 MWe at 2258 when 21 heater drain tank level control valve failed shut.
8/27 Resumed fullload operation (827 MWe) at 1010.
8/29 Reduced load to 680 MWe at 2150 to clean main condenser waterboxes.
8/30 Resumed full load operation (833 MWe) at 0930.
8/31 At the end of this reporting period, Unit 2 was operating at 833 MWe with the reactor at 100% power.
