Maintenance Rule Scoping and Performance Criteria HNP F-BARR FIRE BARRIERS - PSEUDO SYSTEM System Within the Scope of 10CFR50.65 Program: FIRE PROTECTION Unit: 1

Description:

This is the Pseudo system to monitor fire barriers for NFPA-805. The Fire Barrier system includes those fire features or elements identified by the assumptions of the Fire risk analysis. SSCs monitored under the Fire Barriers system include walls, floors, ceilings, fire doors, fire dampers, penetration seals, fire wraps, structural steel fire proofing, and radiant energy shielding **NOTE - the scope of this system is currently undefined. The example monitoring listed within this performance monitoring group are for demonstration only.

Performance Monitoring Group Fire Barriers - Doors in Risk Significant areas / zones Significance:

Enter Value Basis: Included in this performance monitoring group are the doors that were determined to be risk significant based on the multi-compartment analysis of the Fire PRA. **NOTE - the scope of this system is currently undefined. The example monitoring listed within this performance monitoring group are for demonstration only.

Maintenance Rule Scoping and Performance Criteria HNP F-SUPR FIRE SUPRESSION - PSUEDO SYSTEM System Within the Scope of 10CFR50.65 Program: FIRE PROTECTION Unit: 1

Description:

Pseudo system for monitoring the fire safety significant and non significant fire supression systems for NFPA 805 **NOTE - the scope of this system is currently undefined. The example monitoring listed within this performance monitoring group are for demonstration only.

Performance Monitoring Group Fire Supression - Risk Significant Areas/Zone Significance:

Basis: This performance Monitoring group monitors fire supression SSCs located in fire Areas/zones considered risk significant. **NOTE - the scope of this system is currently undefined. The example monitoring listed within this performance monitoring group are for demonstration only.

Interval Criteria Monitoring Goal Basis Definition Start Date Type UNAVAILABILITY N 0 0 Monitoring used is based on a review of plant operating Fire Supression System HOURS experience, industry operating experience, engineering Unavailability assumptions and expert panel recommendations. Condition Monitoring is provided for Fire Suppression SSCs through routine surveillances performance under FPP-0013.

Unavailability monitoring of Fire Suppression systems, assumed as input to the FPRA non-suppression probability function (i.e. 3%), is provided through trending of high fire significant FP SSCs out of service time to ensure the assumption is met. Condition monitoring frequency remains as previously established under the surveillance program outlined in FPP-0013, and unavailability will be provided as equipment hours out of service time per year from data collected following issuance of the SER. *NOTE- Criteria and monitoring intervals have been intentionally left at zero because the monitoring scope and engineering assumptions have yet to be defined. This PMG is for demonstration only.

Performance Monitoring Group Fire Supression - all other Areas /Zones Significance:

Basis: Included in this Performance monitoring group are all the fire supression SSCs monitored in NFPA 805 that are not located in Risk significant areas/zones. **NOTE - the scope of this system is currently undefined. The example monitoring listed within this performance monitoring group are for demonstration only.
