SUMMARY

OF OPERATING' EXPERIENCE-r January 1991-  ;

Theunitbeganthemonthat100%powerj(860MWe). -7 Power was reduced to 80% (680 !!We) from'1300 to 1733 ont2jJanuary. -The power /

reduction. accommodated the removal-of a^condensateidemineralizer from service' while maintaining full condensate flow through the remaining demineralizers.

Power was reduced to 79% - (665 MVe) 'on '4. January.af ter it was discovered that:

there was significant leak-by on :12B -Safety injection- Tank (SIT) outlet check -

valve. An analysis'was performed and. it was. concluded that the Unit could safely operate at full power. The Unit'wasireturned to 100%;(855 MWe) at'1030 on 19 January.

The unit ended the. month at 100% powerL(860 MWe). _
