SUMMARY

OF UNIT 1 OPERATING EXPERIENCE FOR AUGUST 1984 8/l At the beginning of this reporting period, Unit I was operating at 855 MWe with the reactor at 100% power. Load was reduced to 780 MWe at 2025 to clean main condenser water boxes.

8/2 Resumed full load operations (858 MWe) at 0930.

8/4 Reduced load to 710 MWe at 2320 to clean main conderser water boxes.

8/5 Resumed full load operation (853 MWe) at 0600.

8/11 Reduced load to 710 MWe at 2305 to clean main condenser water boxes.

8/12 Resumed full load operation (854 MWe) at 0755.

8/14 Reduced load to 678 MWe at 2206 to clean main condenser water boxes.

8/15 Resumed full load operation (847 MWe) at 0910.

8/18 Reduced load to 670 MWe at 2110 to clean main condenser water boxes.

8/19 Resumed full load operation (851 MWe) at 0840.

8/21 Reduced load to 670 MWe at 0300 to clean main condenser water boxes.

i Resumed full load operation (841 MWe) at 1000. Reduced load to 674 MWe at 2208 to clean main condenser water boxes.

8/22 Resumed full load operation (844 MWe) at 1145. AT 1248 Control Element Assembly (CEA) #2 dropped to the bottom of the core while troubleshooting it s coil power programmer circuit. Power was reduced to less than 70% (562 MWe). Repairs were completed at 1428 and resumed full load operation (849 MWe) at 1825.

8/24 Reduced load to 720 MWe at 2135 to clean main condenser water boxes.

8/25 Resumed full load operation (849 MWe) at 1210.

8/28 At 2158 the reactor was manually tripped due to the reduction of main circulating water flow caused by impingement of a large number of fish on the

+ raveling screens.

SUMMARY

OF UNIT 1 OPERATING EXPERIENCE FOR AUGUST 1984 (Continued) 8/30 The reactor was started up and entered mode 1 at 1600. Startup of the main turbine was delayed by a grounded speed sensing probe which prevented the turbine intercept valves from opening.

8/31 At 1500 placed the unit in mode 2. At 1955 placed the unit in mode 1 and paralleled the unit at 2135. At the end of this reporting period, Unit I was operating at 184 MWe with the reactor at 21% power escalating to 100%

l

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE FOR AUGUST 1984 8/l At the beginning of this reporting period, Unit 2 was operating at 855 MWe with the reactor at 100% power.

8/8 Commenced shutdown at 2158 due to reactor coolant system leakage from 22B Reactor Coolant Pump controlled bleed off line weld.

8/14 Resumed full load operation (833 MWe) at 2000.

8/15 Reduced load to 698 MWe at 2230 to clean main condenser water boxes.

8/16 Resumed full load operation (840 MWe) at 0630. Load was reduced to 786 MWe at 2320 when 21 Heater Drain Tank High Level Dump Valve failed open.

8/17 While returning to full load operation at 0209 26 circulating water pump tripped due to a failed control transformer. Load was reduced to 613 MWe. Resumed full load operation (826 MWe) at 1215.

8/18 Reduced load to 693 MWe at 0614 to clean main condenser water boxes.

Resumed full load operation (832 MWe) at 1310. Reduced load to 693 MWe at 2107 to clean main condenser water boxes.

8/19 Resumed full load operation (853 MWe) at 0915.

8/22 Reduced load to 655 MWe at 0225 to clean main condenser water boxes.

Resumed full load operation (847 MWe) at 0910. Reduced load to 736 MWe at 2205 to clean main condenser water boxes.

8/23 Resumed full load operation (842 MWe) at 0900.

8/25 At 2110 load was reduced to 700 MWe to facilitate testing of the main turbine throttle and governor valves and to clean condenser water boxes.

8/26 Resumed full load operation (847 MWe) at 0845.

8/31 At the end of the reporting period, Unit 2 was operating at 848 MWe with the reactor at 100% power.
