1- PAGE o OF 1 Monthly Summary Unit i began the month with work continuing to return to service following a Steam Generator Feed Pump failure. The feed pump is being replaced with the pump internals from Unit 2 with work on design modifications to be implemented on all three Steam Generator Feed Pumps.

The unit went back on line 6/13/88 and continued power ascension testing at the 30% plateau.

On 6/23/88 the unit was successfully shutdown from outside the control room marking the completion of the final test at the 30% level of the power ascension testing program.

Unit I was restarted on 6/24/88 and achieved 50% reactor power 6/27/88 for the start of testing at the 50% plateau.
