NRC MONTHLY OPERATING REPORT OPERATING

SUMMARY

FEBRUARY-1984 UNIT 1 The Unit started the month at 94% power due to a suspected tube degradation in the "A" OTSG.

On February 6, the Unit's power level was further reduced to 92% due to a slight increase in the "A" OTSG tube leak rate. The Unit remained at this power level throughout the end of the month.
