OPERATIONAL

SUMMARY

JUNE 1989 UNIT 1

. Unit I continued to operate well during June.

It' generated 814,120 MWh of electrical power with a capacity factor of 95.2 percent.

Power had been reduced to 58 percent at the end of May for maintenance on heater drain tank pump 3 motors 3A and 3C. This maintenance was completed on June 2, 1989, and

...the reactor reached 100 percent power'again on June 3, 1989. Unit I was 4

operating at 100 percent power at the end of June.

UNIT 2 Unit 2 continued to operate well during June.

It generated 837,800 MWh of electrical, power with a capacity factor of 97.7 percent.

The power level was-reduced to 80 percent on June-13, 1989 to repair the seal injection H O 2

coupling on condensate demineralized booster pump 2A.

Reactor power level was returned to 100 percent on June 14, 1989 after maintenance was complete.

Unit 2 was operating at 100 percent power at the end of June.
