LOSS OF OFFSITE POWER
~
l' I".
PURPOSE The purpose of this instruction.is'to provide operator action for a loss of offsite power.
Since loss of..offsite power will cause a reactor trip, emergency instructions should be used to handle the event.
This instruction will only handle the electrical portion (e.g., monitoring D/Gs, loading additional equipment on D/Gs and restoring offsite power) of loss of offsite power.
