These figures wdl be used to plot a g:aph for each reporung month. Note that when rnaximum dependable capacity is used for the net electncal rsting of the unit, there may be occasions when the daily average power level exceeds the ICCT, line (or the restricted power level line). In such cases, the average daily unit power output sheet should be foomoted to explain the apparent anomaly.

84-27 10/13/84 F 20.3 A 2 84-109 HA INSTRU C Plant shutdown due to cycling of turbine governor

& by-pass valves. It was determined after shutdown that cycling was caused by radio frequency inter-ference due to keying of hand held radio trans-mitters in the vicinity of electrosyn pressure transmitters.

All susceptable ir.strument locations were iden-tified and warning signs were placed in the area of DEH pressure transmitters. Action is also being taken to evaluate the possibility of modifying electrosyn transmitters to reduce

! I sensitivity to radio frequency interference.
