s electrical output as measured at the output terminals of the turbine-generator during the most restrictive seasonal conditions less the normal station service loads. The net Design Electrical Rating is the nominal net electrical output of the unit specified by the utility and used for the purpose of plant design. 3. Note that this item is applicable only if restric tions on the power level are in effect. Short-term (less than one month) limitations on power level need not be presented in this item, since one of the important purposes of the item is to determine if, and at what power level, a restricted power level line should be drawn on the chart of average daily reactor power. Since this information is used to develop figures on capacity lost due to restrictions and because most users of the "Operating Plant Status Report" are primarily interested in energy actually fed to the distribution system, it is requested that this figure be expressed in MWe-Net in spite of the fact that the figure must be derived from MWt or percent power. 4. Reasons for Restriction (if Any). If item 3 is used, item 4 explains why. Brief narrative is acceptable. Cite references as appropriate. Indicate whether restric tions are self-imposed or are regulatory requirements. Be as specific as possible within space limitations. Plants in startup and power ascension test phase should be identified here. 5. Show the total number of hours the reactor was critical during the gross hours of the reporting period. 6. Reactor Reserve Shutdown Hours. The total number of hours during the gross hours of reporting period that the reactor was removed from service for administrative or other reasons but was available for operation. 7. Hours Generator 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. These hours, plus those listed in Appendix D for the generator outage hours, should
