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 dall-r unit power output sheet should be footnoted to explain the apparent anomaly.

1. Monthly Report for Braldwood Unit 2 A. Summary __oL0porating_ Experience Draldwood Unit 2 entered the month of May at approximately 99% reactor power. Routine operatlon continued up to May 12, 1991 when the first of two forced outages for the mor. ' occurred. The unit was manually shutdown (cold shutdown) to repair a talled containment isolation valve.

The unit was returned to service on May 20, 1991. On May 26, 1991 a forced power redut lon along with the generator being taken off line occurred to make repairs to the turbine electrohydraulle control system. The reactor remained critical during this short power reduttlon, Following repairs, the unit continued routine operation the remainder of the month.
