During the 2011 Triennial fire protection … During the 2011 Triennial fire protection inspection, it was determined that the off normal procedure for control room evacuation due to fire has two defects. It does not adequately protect the steam generators from overfilling and possibly damaging the turbine driven auxiliary feedwater pump. In addition it does not protect the reactor coolant system pressurizer from filling to above 100% indicated water level, possibly causing the primary system to go solid. Both of these issues are results of inadequate assumptions used in the Post Fire Safe Shutdown Analysis of a fire in the Control Room.</br>Compensatory measure of hourly fire watch for the control room is in place. The procedure for control room evacuation due to fire is being revised to include compensatory actions that will address the above events.</br>The NRC Resident Inspector has been notified.
