Loss of the condensate system for 25 minutes results in cooling down to LPI using the ADVs. If NO HWPs are operating, continuing this enclosure to restore the condensate system is a priority unless the CR SRO deems EOP activities higher priority. The 25 minute criterion is satisfied when a HWP is started and iC-iC is 10% open.

If the condensate system is operating, the remaining guidance establishes FDW recirc, monitors and maintains UST, and transfers EFDW suction to the hotwell if required.

12. Notify CR SRO to set priority based on the NOTE above and EOP activities.

__Time Position Applicants Actions or Behavior Crew Response:

EXAMINER NOTE: Initially, ES Channels 1 and 2 will actuate when RCS pressure decreases below 1600 psig. When Reactor Building pressure increases to> 3 psig, ES Channels 3-6 will actuate. The exact path through End. 5.1 is somewhat dependant on timing of ES 3-6 in conjunction with the pace of progress through the enclosure. If the RO reaches Step 15 prior to ES 3&4 actuation, the procedure directs going to Step 53. When ES Channel 3&4 actuate, the RO should review IAAT Steps 3, 9, 10, and 15 and perform any required actions With ES-I in Manual due to event I, Diverse HPI will position Channel 1 ES components to their ES positions.

The 25 minute criterion is satisfied when a HWP is started and IC-b is 10% open.

If the condensate system is operating, the remaining guidance establishes FDW recirc, monitors and maintains UST, and transfers EFDW suction to the hotwell if required.
