As part of an ongoing Appendix R assessment, it has been determined that Operator actions credited in the Fire Hazards Analysis (
FHA) potentially would not be met in fire zones credited for post fire
safe shutdown per
10 CFR 50 Appendix R. Specifically, the
FHA credited the availability of two in plant operators to conduct two separate series of operator actions that are required to be performed simultaneously within the first 20 minutes. However, the site Fire Plan requires one of these in plant operators to respond to a plant fire as a Fire Brigade member. Since no barrier was put in place to compensate for the lack of the credited operator; this event is reportable as an
unanalyzed condition that significantly degraded plant safety.
The licensee notified the NRC Resident Inspector.

Further review has determined that adequate operator resources are and have been available to perform the required post fire safe shutdown actions. Therefore, this event is not an unanalyzed condition that significantly degrades plant safety and is being retracted.
