1043 INSTRUCTIONS On this form, list the average daily unit power level in Mac.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 1007o linc (or the restricted power level line). In such cases, the average daily unit power output sheet should "b.

Increased power to 100%%d 771211.

114 771214 A 4 Reduced reactor power to 45%%d due to problem with condensate booster pumps. Further re=

duced power to 30%%d due to condenser tube leakage. Increased power to 100K 771215.

P 115 771223 Reduced reactor power to 74%%d for noderator temperature coeffi cient surveil.lance test.

Increased power to 100Ã 771224.

116 771228 A Reduced reactor power to 74K to permit cont ol c valve testing due to EHC system low oil pre sure problem. Power increase delayed due to fai of diaphragm valve i: 're on CVCS holdup tanks.

Increased power to 100%%d 771230.

SUMMARY

Unit operated at 100%%d power except for above noted outages.
