SUMMARY

- DECEMBER, 1981 UNIT 1 Unit One began the month at 85.97% full power. The unit is in a power

limited condition due to fouling of the "A" Steam Generator. Periodic

! power adjustments have been required throughout the month to prevent flooding of the feedwater nozzles. Unit One ended the month at 88.30%

full power with further power adjustments anticipated.
