| Title | Unanalyzed Condition - Fire Organizational Plan No Longer Aligned with Safe Shutdown Analysis |
| Event Description | It has been identified that during a revision change between Revision 5 of FOP 1.2 (July 20, 2004), and Revision 6 of FOP 1.2 (November 1, 2004), a number of omissions of safe shutdown equipment occurred. Because of these omissions, FOP 1.2 is no longer aligned with the Safe Shutdown Analysis. As a result, some of the manual actions that would be necessary to accomplish safe shutdown are no longer identified in FOP 1.2.
FOP 1.2, Fire Organizational Plan is used by Operations to provide guidance on plant operation for fires within safe shutdown areas. Included in this guidance is a list of safe shutdown equipment affected by a postulated fire and the manual actions that may be required to compensate for the fire damage. It has been determined that this condition is reportable because the missing procedural guidance may result in safety significant operator actions not being performed which are credited in the Safe Shutdown Analysis. Corrective actions have been entered into the Corrective Actions program, and a procedure revision to correct FOP 1.2 is currently in progress. The licensee notified the NRC Resident Inspector. |
