'Iho follcwing report Alghlights the operatirg experimoe of Wolf Creek Generating Statico for the Inanth of February,1991. This report is being provided pursuant to Technical Specification 6.9.1.8.

I.

SIM%RY OF OPERATDG EXPERIDCE The unit operated continuously throughout the month of February 1991. The unit began the month at 90% power with power being further reduced to 80% on February 5.

These power levels are being mintained for fuel conservation purposes. Power ru mined at 80% for the ru minder of February with the exception of a sixteen hour period beginning late february 14, when power was ruiuced to 75% as a result of a min geerator stator cooling instrumentation prob 1 m.- 'Ihe instrumentatico probim was corrected and the unit returned to 80% pp.er February 15, 1991.

II. MMOR SAFETY REATED MAINTENA!CE ACTIVITIES 1.

Replacenont of hydraulic punp on min steam isolation valve AWV11.

2.
