Title:

Station Blackout No.: 05-1-02-1-6 Revision: 11 Pace: 1 1.0 PURPOSE / DISCUSSION 1.1 The purpose of this procedure is to provide guidance to the operators in the event all onsite and offsite AC powers are lost, and the estimated time available to restore AC power is 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />.

1.2 This proc.edure will interface with ONEP 05-1-02-I-1 Reactor Scrarn, ONEP 05-1-02-I-4 Loss of Offsite Power, Emergency Procedures, and the Emergency Plan.

1.3

.a This procedure assumes loss of all three(3) Emergency Diesel Generators,

concurrent with the loss of all offsite power. -=*

'*f ' '

1.4 -

It l's assumed that all station and non-divisional batteries are availableffy b' in a fully charged status.

1.5 This procedure gives direction for establishing backup Emercency Power I via the Gas Turbine Generator (GTG) system.
