Regulatory Commitment and Completion Schedule Commitment Committed Completion Date Commitment Tracking Number Status The resolution of Fire PRA Suggestion F&O FSS-B1-03 was determined to be an upgrade during F&O closure review. The upgrade was not reviewed at the time of identification and has not yet been reviewed by an independent peer review. To resolve FSS-B1-03 and also close NFPA-805 LAR Table S-3 Implementation item 13-805-001, the Fire PRA was updated to perform the Human Reliability Analysis (HRA) evaluations for MCR abandonment using detailed assessments within HRA Calculator rather than the screening values discussed in this F&O. This change was determined by a recent independent peer review team to be an upgrade. PRA scope and technical adequacy guidance requires upgrades to be independently peer reviewed and Finding F&Os to be closed, or dispositioned for a given application. Therefore, Ameren Missouri will conduct a focused scope peer review on this upgrade and close any new Finding F&Os using an endorsed closure process.
Prior to using the Fire PRA to support implementation of any alternative treatments under the 10 CFR 50.69 application.
