STPEGS Unit 2 experienced an automatic reactor scram during February 1993 and subsequently remained shutdown due to auxiliary feedwater system component failures. While the unit was shutdown, corrective maintenance was performed and organizational and work process changes were implemented, q l

Upon the resolution of the auxiliary feedwater system component failures l and the additional issues, efforts were resumed on the refueling and scheduled l maintenance outage.

l l

On 5/17/94 the Nuclear Regulatory Commission acknowledged completion of the l Confirmatory Action Letter issues associated with Unit 2 and authorized the I restart of the unit in accordance with the startup and power ascension plan.

The unit was returned to service on 5/30/94 at 0202 and concluded the )

reporting period operating at 40% reactor power with the power ascension testing 1 program in progress.
