hours during the gross hours of the reporting period that the unit operated with breakers closed to the station bus. These hours, plus those listed in Appendix D for the generator outage hours, should equal the gross hours in the reporting period. 8. Unit Reserve Shutdown Hours. The total number of hours during the gross hours of the reporting period that the unit was removed from service for economic or similar reasons but was available for operation. 9. Gross Thermal Energy Generated. The thermal output of the nuclear steam supply system during the gross hours of the reporting period, expressed in megawatt hours. 10. Gross Electrical Energy Generated. The electrical output of the unit measured at the output terminals of the turbine-generator during the gross hours of the reporting period, expressed in megawatt hours. 11. Net Electrical Energy Generated. The gross elec trical output of the unit measured at the output terminals of the turbine-generator minus the normal station service loads during the gross hours of the reporting period, expressed in megawatt hours. Negative quantities should not be used. If there is no net positive value for the period, enter zero. 12-18. For units still in the startup and power ascension test phase, items 12-18 should not be com puted. Instead, enter N/A in the current month column. These seven factors should be computed starting at the time the unit is declared to be in commercial operation. The cumulative figures in the second and third columns should be based on commercial operation as a starting date. However, units already in commercial operation, for which cumulative figures have been based on different starting dates, need not recalculate the cumula tive figures. 1.16-11 12. Reactor Service Factor. Compute by dividing hours reactor was critical (item 5) by the gross hours in the reporting period (item 1). Express as percent to the nearest tenth of a percent. During months when the unit is shut down for the entire period
