Compute to the nearest whole megawatt.

These figures will be used to plot a graph for each reporting month. Note that by using maximum dependable capacity 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.

75-8 061575 F 3.8 G 3 Reactor trip caused by high steam flow with low Tavg resulting from unequal pressure between steam generator and header and rapid header isolation valve opening.

75-9 061675 F 4.0 A 3 Malfunction of EHC caused turbine to roll at a high rate as the governor valves opened spiking 1st stage pressure above 15 per cent which tripped turbine.

Turbine trip, caused reactor trip.
