[en] This report documents the technical evaluation of the adequacy of the station electric distribution system voltages for the Nine Mile Point Nuclear Station, Unit 1. The evaluation is to determine if the onsite distribution system in conjunction with the offsite power sources has sufficient capacity to automatically start and operate all Class 1E loads within the equipment voltage ratings under certain conditions established by the Nuclear Regulatory Commission. The analysis submitted demonstrates that the station's electric distribution system supplies adequate voltage to the Class 1E equipment under worst case conditions
