FPR RAI This was the RAI that was added to the draft that you saw in the meeting. As I mentioned on the call VI-1 is being listed as resolved during the last meeting and VI-2 is being dropped. Also II-6 looked to be reworded as discussed during the meeting. Other than that the questions should be the same as you saw other than minor editorial corrections.

Justin C. Poole Project Manager NRR/DORL/LPWB U.S. Nuclear Regulatory Commission (301)4152048 email: Justin.Poole@nrc.gov RAI FPR II11 In Part II, Section 14.10.3 [pg. II58], a change was made to the approved version of the FPR to allow an evaluation to be performed to justify using alternate means to provide Fire Safe Shutdown (FSSD) when required equipment cannot be returned to Operable status within the required time.

Provide a summary evaluation and technical justification that supports this change.

Additionally, discuss the status of the alternate means going forward. For example, What would be the duration of the alternative?

Would the alternative become the primary means of achieving FSSD?

Would the new systems/equipment/components need to be added to the FSSD analysis, and the old systems/equipment/components removed from the analysis?

This RAI involves an update to the FPR to incorporate the response to the RAI.
