STPEGS Unit 2 began the reporting period at 1004 reactor power,  !

On 11/20/92 et 2200 reactor power was reduced to 80s to allow scheduled corrective realntenance on the #23 main feedvater ptunp, Reactor power was further reduced to 60% on 11/21/92 at 1813 due to a trlp occurring on the #24 start up feedwater purop. . Corrective innintenance was cornpleted on the #24 start.up.

feedwater allowing power restoration to 80% on 11/23/92 at 0647. Following the scheduled correctivo inaintenance on the #23 rnain feedwater pump, reactor power was restored to 100% on 11/24/92 at 2234.

The unit completed the reporting period operating at 1004 reactor power.
