A: The NRC staff finds that the disposition of the F&O as described by the licensee in the LAR or its supplements provides confidence that the issues raised by the F&O have been addressed and, if needed, the PRA has been modified, and therefore the resolution of the F&O is acceptable for this application.
B: The NRC staff finds that the disposition of the F&O as described by the licensee in the LAR and its supplements and further clarified during the audit provides confidence that the issues raised by the F&O have been addressed and, if needed, the PRA has been modified, and therefore the resolution of the F&O is acceptable for this application.
C: The NRC staff finds that the resolution of the F&O, as described by the licensee in the LAR or its supplements, would have a negligible effect on the evaluations relied upon to support fire risk evaluations and has no impact on the conclusions of the risk assessment and therefore the resolution of the F&O is acceptable for this application. Examples of such F&Os may be suggestions, as well as those F&Os that don't affect the fire PRA. Documentation issues may fall into this category as well.

RAI Response Not Discussed in SE Discussed in SE IE-A8 See PRA-RAI-15a. Acceptable to the NRC staff because the licensee conducted formal interviews with licensed operators, Shift Technical Advisors, and system engineers and no new internal events initiators were identified.
SY-A4 See PRA-RAI-15b. Acceptable to the NRC staff because plant walkdowns were performed and a preliminary determination was made that there are no discrepancies between the PRA and as-built as-operated plant.

A: The NRC staff finds that the acceptability basis for the capability category of the SR as described by the licensee in the LAR and its supplements provides confidence that the requirements of the SR have been addressed and, if needed, the PRA has been modified, and therefore the PRA quality with respect to the SR is acceptable for this application. Examples of acceptable Not Met and CC-I SRs are modeling methods that yield conservative FRE and change evaluation results.
