OPERATIONAL

SUMMARY

MARCH 1996 l UNIT 1 Unit I generated 494,822 megawatthours (MWh) (gross) electrical power during March with a capacity factor of 57.78 percent. Unit I was manually removed from service on March 2,1996, at 0348 EST for a planned maintenance outage for the No. 2 reactor coolant pump motor and seal replacement. Unit I was taken critical on March 13 at 2212 EST and was tied to the grid again on March 14 at 0927 EST. Unit I reached i 100 percent reactor power on March 16 and continued to operate at 100 percent through the end of March.

t UNIT 2 Unit 2 generated 880,760 megawatthours (MWh) (gross) electrical power during March with a capacity factor of103.30 percent. There were no outages or power reductions of greater than 20 percent to report during March. Unit 2 was operating at 100 percent reactor power at the end of March.

Reactor' 5 960302 S 293.7 B 1 N/A AB P Unit I was manually removed from senice for a planned maintenance activity invohing the No. 2 reactor coolant pump (RCP) motor and seal replacement. The RCP developed a leak at the No. 3 seal. The leak resulted in boric acid build up on the RCP motor cooler restricting air flow causing an increase in the motor temperature. The RCP motor temperature has been stable for the past month. The RCP was replaced to facilitate future outage needs. Unit I was taken critical on March 13 at 2212 EST and uns tied to the grid on March 14 at 0927 EST.

Unit I was operating at 100 percent reactor power again on March 16.
