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 1007. 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.

II. Monthly Report for Braidwood Unit 2 A. S.UEnary_.of Ooerating EXP.ET_lknit Braidwood Unit 2. entered the month of August 1992 at apprcximately  !

4 99% reactor power. On August 1, power was reducedEto obtain an )

, oil sample and vibration readings for the 2C reactor coolant pump '

1 due to an increase in the motor thrust bearing temperature. Test results were satisfactory and power was increased. On August 8, power was reduced to observe the oil levels for the reactor l j coolant pump motors. Results were satisfactory and power was

increased. On August 15, while decreasing power per the load dispatcher, a rod drive urgent failure occurred. Power was increased after the rod drive power supply was repaired and rod i drive testing comoleted. The Unit operated routirely through the

, end of the month.
