NFPA 805 Transition NFPA 805 Monitoring Program Oconee / Harris NFPA 805 Pilot Observation Meeting April 14-16, 2008 Charlotte, NC Keith Began, CES/FP

NFPA 805 Monitoring Program Review from Nov. 2007 Pilot Meeting O Assumptions Z Assumptions that are not subject to change do not need to be monitored (e.g. ceiling height input maintained by configuration control process)

Z Deterministic monitoring may carry forward as current surveillance processes Z The level of monitoring of assumptions and performance should be commensurate with associated risk significance O Considerations Z Align with existing programs and processes 3/4 Eliminate/minimize need for new, separate processes Z Consider the Human Performance aspects of our people in the field Z May use Maintenance Rule-like type program Z One method may not fit all attributes Z Use Leading Indicators (if determined)

O Phase 1 - Scoping (SSCs, Program Elements, Assumptions)

Z Key Assumptions in Engineering Analyses 3/4 Identify the key assumptions from the risk-informed, performance-based analysis that apply to a fire protection feature.

3/4 For each applicable feature, identify which characteristics require monitoring to ensure the key assumptions are maintained.

3/4 For each performance criteria, identify the monitoring that would be needed to ensure the characteristic is maintained.

3/4 Establish threshold values that would be used to identify when the characteristic is in jeopardy of not being maintained.

ssumptions that are not subject to change do not need to be monitored. The level of monitoring of assumptions should be commensurate with their risk significance.

O Phase 2 - Establishing Risk Criteria Z Risk Significant Criteria 3/4 Fire PRA is primary tool Z Performance Criteria 3/4 Established for items within the NFPA 805 monitoring scope, regardless of their ability to be measured using risk significant criteria 3/4 The performance criteria used should be availability, reliability, or condition monitoring, as appropriate Page 7

NFPA 805 Monitoring Program Program Development (Update since Nov. 2007 )

O Phase 3 - Risk Determination Z Use Fire PRA, or other processes, to determine the risk significant SSCs/fire protection program elements using the criteria established in Phase 2.

O Phase 4 - Monitoring Implementation Z Tools 3/4 Tracking database 3/4 Corrective Action 3/4 EGR-NGGC-0008, Engineering Programs 3/4 Existing Procedures Z Assess performance against established criteria 3/4 Refinement of performance goals and criteria 3/4 Analysis of situations where goals are not met, or declining trends 3/4 Address items appropriately via Corrective Action NFPA 805 monitoring program scope is not included in the scope of Maintenance Rule. For convenience, the Maintenance Rule monitoring process will be used to facilitate use of existing programs and processes (e.g., use of tools such as tracking databases).
