/ REDUCTIONS MBIN COMPLETED BY TELEPi ONE (509) 377-2486 PREVE T R C fRENC Plant was forced down by low OEH control system pressure.

A broken nipple on autostop hydraulic oil system resulted I

i in decreasing OEH pressure which forced a rapid downpower with a manua] scram being initiated at 40K peer. Repairs were oade and the hydraulic system tested prior to returning unit to service.

I RH36 9/22/90 S Reduced power to perfem a control rod sequence exchange.

l. WNP-2 incurred one forced outage and one power reduction in Septetber as described above.

1064 INSTRUCTIONS On this form, list 'the average daily unit power level in a(We-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 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.
