I. Monthly Report for Braidwood Unit 1 A. Summarv of Operatina Experience The unit entered the month at approximately 95% Reactor Power. On January 19, 1989, the unit was taken off line to find the source of a Reactor Coolant System Leak. The

-unidentified' leak was~ approximately 0.8 GPM. . The leak was found to be at the Pressurizer Manway. Repairs were made, and the unit. is scheduled to be returned to service in early February.

On this form list the average daily unit power level in MHe-Net for each day in the reporting month. Compute to the nearest whole megawatt. ,

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 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.
