The unit began the month shutdown because of the continued refueling outage. The refueling i outage ended May 18, IV>4 when the unit was paralleled to the grid at 2215. The unit was removed  !

from the grid on May 20, IV)4 at 0150 for Main Turbine testing. After completion of the Main Turbine testing and during paralleling to the grid procedure, there was an electrical ground detected. l The ground was corrected at 1600 on May 20, IV>4. The unit was again paralleled to the grid on May  ;

20,1994 at 1700.  !

i At 1856 on May 26, IV14 the unit was again removed from the grid to allow for installation of a halance shot in Main Bearing #8. During start.up procedures, Main Turhine llearing #7 experienced high ternperature and the unit was shutdown to repair the bearing.

The unit ended the month in a shut-down condition in mode 5.

SUMMARY

OF OPERATING EXPERIENCE May 1994 The unit began the month at 100% Reactor power (850 MWe).

On May 15,1994 commenced reducing Reactor power for a planned outage to complete Surveillance Test Procedures. The unit was removed from the grid on May 15,1994 at 2130. After completion of the Surveillance Tests, the unit was started and paralleled to the grid on May 22,1994 at 2217.

On May 23,1994 reduced Reactor power to 65% to perform maintenance on 21 Steam Generator Feed pump. Following completion of the Steam Generator Feed Pump maintenance Reactor power was increased, reaching 100% power at 1340 on May 25,1994.

The unit continued to operate the remainder of the month at 100% Reactor power.
