1. Design Electrical Rating (Net NMe). 778.0 N'A NMA The nominal net electrical output of the unit specified by the utility and used for the purpose of plant design.

2. Maximum Dependable Capacity (Net MbVe): 764.0 N'A N!A The gross electrical output as measured at the output terminals of the turbine-generator during the most restrictive seasonal conditions minus the normal station service loads.

3. Number of Ilours the Reactor Was Critical. 562.9 7.574.0 206.590.3 The total number of hours during the gross hours of the reporting period that the reactor was critical.

4. Number of I lours the Generator Was On Line. 546.6 7.556.4 203.662.7 (Also called Service Hlours). The total number of hours during the gross hours of the reporting period that the unit operated with the breakers closed to the station bus.

The sum of the hours the generator was on line plus the total outage hours should equal the gross hours in the reporting period.

5. Unit Reserve Shutdown flours. 0.0 0.0 0.0 The total nunsher of hours during the gross hours of the report ing period that the unit was removed from seenice for economic or similar reasons but was available for operation.

6. Net Electrical Energy IiMWIll. 399.430.0 5.648A47.0 138.802A52.0 The gross electrical output of the unit measured at the output tenusinals of the turbine-generator minus the nrwmal station service loads during the gross hours of the reporting period. expressed in inega-watt hours. Negative quantities should not be used.
