2-6* Monitoring.
A monitoring program shall be establishe d to ensure that the availability and reliability of the fire protection systems and features are maintained and to assess the performance of the fire protection program in m eeting the performance criteria. Monitoring shall ensure that the assumptions in the engineering analysis remain valid. 2-6.1 Availability, Reliability, and Performance Levels. Acceptable levels of availability, reliability, and performance shall be established.
2-6.2 Monitoring Availability, Reliability, and Performance.
Methods to monitor availability, reliability, and performance shal l be established. The methods s hall consider the plant operating experience and industry operating experience.
2-6.3 Corrective Action. If the established levels of availability, reliability, or performance are not met, appropriate corrective actions to return to the established levels shall be implemented.
Monitoring shall be continued to ensure that the corrective actions are effective."2.3 Assumptions.
The following assumptions are provided to perform a deterministic analysis of ensuring the nuclear safety performance criteria are met. [Perform ance-based information (i.e., equipment out of service, equipment failure unrelated to th e fire, concurrent design basis events) are integral parts of a PSA and shall be considered when performance-based approaches are utilized.]2.4.2.1 Nuclear Safety Capability Syst ems and Equipment Selection
-Availability and reliability of equipment selected shall be evaluated."
Section 2.4.3.3 of NFPA 805 discusses PSA analyses pe rformed to support fire risk evaluations:
"2.4.3.3* The PSA approach, methods, and data shall be acceptable to the AHJ. They shall be appropriate for the nature and scope of the chang e being evaluated, be based on the as-built and as-operated and maintained plant, and refl ect the operating experience at the plant."
Industry Guideline for Monitoring th e Effectiveness of Maintenance at Nuclear Power Plants
2-6.2 Monitoring Availability, Reliability, and Performance.
Methods to monitor availability, reliability , and performance shall be establ ished. The methods shall consider the plant operating experience and industry operating experience.
