SUMMARY

OF UNIT 1 OPERATING EXPERIENCE AUGUST 1983 8/l At the beginning of this reporting period, Unit I was operating at 820 MWe with the Reactor at 100% power.

8/4 At 2155 load was reduced to 711 MWe to investigate saltwater leakage into the main condenser.

8/5 Load was increased to 845 MWe at 0930 when indications of saltwater leakage disappeared.

8/14 At 1330 power was reduced to 809 MWe per Technical Specifications when the plant computer failed, rendering the output from the in-core instruments inoperable.

8/15 Resumed full load operation (844 MWe) at 0625.

8/17 At 0840 load was reduced to 750 MWe to investigate saltwater leakage into the main condenser.

8/18 Load was increased to 850 MWe at 0205 when indications of saltwater leakage disappeared.

8/21 Operating at reduced load (732 MWe) at 0010 while testing Main Turbine Control Valves. Load was increased to capacity (844 MWe) at 0732.

8/21 At 0908 load was decreased to 794 MWe to replace a shearpin in a Traveling Screen. Resumed fullload operation (843 MWe) at 1450.

8/23 At 0525 load was reduced to 707 MWe to investigate saltwater leakage into the main condenser. Load was increased to 841 MWe at 2045 when indications of saltwater leakage disappeared.

8/27 The unit was taken off the line at 0430 to investigate low indicated oil level in 12A Reactor Coolant Pump Motor. At 1236 the unit was paralleled after adding oil to the Reactor Coolant Pump Motor. At 1426 the Reactor tripped due to High Axial Shape Index. The unit was paralleled at 1840 and held at 12% power due to High Axial Shape Index.

SUMMARY

OF UNIT 1 OPERATING EXPERIENC, E.

AUGUST 1983 8/28 Load was increased to 829 MWe at 1720.

8/29 At 0430 load was reduced to 708 MWe to investigate saltwater leakage into the main condenser. Load was increased to 834 MWe at 1820.

8/31 At 0600 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 Traveling Screens.

8/31 At the end of this reporting perod, Unit I was shut down.

Z SUMM ARY OF U_ NIT 2 OPERATING EXPERIENCE AUGUST 1983 i

8/1 At the beginning of this reporting period, Unit 2 was operating at 850 MWe with ~

the Re' actor at 100% po'wer. '

~

8/9 At 1810 the Reactor was manually tripped in response to increasing primary

~

temperature when the' Main Turbine Governor Valves spuridusly shut. 2 8/13 Resumed full load operation (795 MWe) at 1924.

8/18 At 2320 load was decreased to 780 MWe to replace the oilin 23 Ci-culating Water Pump lower bearing. s 8/19- - Load was increased to capacity (810 MWe) at 1100.

8/22 At 1541 the Reactor was manually tripped in response to increasing primary temperature when the Main Turbine Governor Valves spuriously shut.

8/24 Resumed full load operation (815 MWe) at 1000.

8/24 At 1336 the Reactor tripped on Reactor Coolant System high pressure when the Main Turbine Governor Valves and Intercept Valves spuriously shut.x 8/26 Resumed fullload operation (819 MWe) at 1445.

S/31 At 1238 commenced shutdown in accordance with Technical Specifications because of the suspected inability of the Feedwater Control System to' reduce feed flow adequately following a Reactor trip. At 1749 the Reactor tripped on' Low Steam Generator Level from approximately 25% power following the loss of the only operating Feed Pump. ,

8/31 At the end of this reporting period, Unit 2 was shut down.
