OPERATIONS

SUMMARY

SEPTEMBER,1987 The unit entered September operating at 100% power.

On September 1,1987 plant. power was reduced to approximately 73% and returned to full capacity following ~ repair of the "B" main feedwater pump coupling.

The plant continued at 100% power until September 16th when a turbine trip caused a reactor trip.

The turbine trip was the result of high moisture separator level.

The plant was returned to 100% power the following day and remained at that capacity for i

the remainder of the month.

'J MAJOR SAFETY RELATED MAINTENANCE 1

During the month of September, TMI Unit 1 performed no major maintenance on safety related equipment.
