LIST OF COMMITMENTS The following table identifies those actions committed to by Ameren Missouri in this document. Any other statements in this document are provided for information purposes and are not considered commitments. Please direct questions regarding these commitments to: Justin Hiller at 314-225-1141.
COMMITMENT Due Date/Event COMN The resolution of Fire PRA Suggestion F&O Prior to using the 50437 FSS-Bl-03 was determined to be an upgrade Fire PRA to during F&O closure review. The upgrade was support not reviewed at the time of identification and implementation has not yet been reviewed by an independent of any alternative peer review. To resolve FSS-Bl-03 and also treatments under close NFPA-805 LAR Table S-3 the 10 CFR 50.69 Implementation item 13-805-001, the Fire PRA application.
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.
