The nominal net electrical output of the unit specified by the utility and used for the purpose of plant design.
2 Maximum Dependable Capacity (MWe-Net).
The gross electrical output as measured at Ihe output terminals of the turbine-generator during the most restrictive seasonal conditions minus the normal station service loads.
3 Number of Hours the Reactor Was Critical.
The total number of hours during the gross hours of the reporting period that the reactor was critical.
4 Number of Hours the Generator Was On Line.
(Also called Service Hours). The total number of hours during the gross hours of the reporting period that the unit operated with breakers closed to the station bus.
