Monthly Report for Braldwood Unit 1 A.
Surgtary. 0LOpet ating_EspeIitnce Dialdwood Unit 1 enter ed the month of October at approultnotely 98% power.
The unit operated routinely until October 6, 1991 when power was reduced to repals a sightglass on a reactor coolant purnp oil reservoir.
On October 10, 1991 power was again tedvted and the generator taken of f line to repalr a f ailed condensete polisher strainer and to clean up feedwater chemistry. The unit returned to rout.ine operation on October 14, 1991 and continued operating routinely through the remainder of the month.

INSTRUCTIONS On this form list the average daily unit power level in MWe-Net for each
. day in the reporting month.
Compute to the nearest whole megawat t.
These figures will be used to plot a graph for each reporting month.
Note that when maximum dependable capacity is used for the net electrical rating of the unit there may be occasions when the daily average power level exceeds the 100% line (or the restricted power level line).
In such cases the average daily unit power output sheet should be footnoted to explain the apparent anomaly.
Due to condenser efficiency.
