Dear Sir or Madam:

JAFP-14-0128 Page 2 of 2 On March 12, 2012, the NRC issued Reference 1 to all power reactor licensees.

By Reference 2, Entergy Operations, Inc. (Entergy) provided the Seismic Hazard and Screening Reports for James A. FitzPatrick Nuclear Power Plant (JAF) requested by Reference

1. In Reference 3, JAF responded to a request tor additional information (RAI). The NRC contacted JAF to discuss the responses and based on the telecom communications three issues are being addressed by this letter. First, provide a basis for the IPEEE high confidence of a low probability of failure (HCLPF) Spectrum (IHS) for the block walls at JAF. This basis is contained in the Enclosure.

Second, in the RAI response [Reference 3] JAF stated its intention to perform a Relay Chatter Review. The Nuclear Energy Institute (NEI) letter dated April 9, 2013 [Reference 5] proposed a schedule to implement the Fukushima Near-Term Task Force (NTTF) Recommendation 2.1. JAF committed to follow this schedule [Reference 4]. This schedule includes a group of risk evaluations due by June 30, 2017. Subsequently, a new NEI letter dated October 3, 2013 [Reference 6], proposed that the industry should also perform Relay Chatter Reviews. With this letter JAF commits to perform the Relay Chatter Reviews at the same schedule as the risk evaluations.

Third, the Seismic Hazard and Screening Report [Reference 2] concluded that JAF screened out of the High Frequency Confirmation and the seismic risk evaluation (seismic probabilistic risk assessment (SPRA), or a seismic margin assessment (SMA)); however, upon further evaluation, JAF will continue to perform the High Frequency Confirmation per the commitment made in Reference

4. In conclusion, the evaluations to be performed per the NEI schedule [Reference 5] include Spent Fuel Pool Evaluation, High Frequency Confirmation, and Relay Chatter Review. In addition, JAF will submit the Expedited Seismic Evaluation Process (ESEP) by December 31, 2014, per the NEI schedule.

This letter contains a new regulatory commitment in the Attachment.

If you have any questions regarding this letter, please contact Chris M. Adner, Regulatory Assurance Manager, at 315-349-6766.

I declare under penalty of perjury that the foregoing is true and correct. Executed on 5th day of December, 2014. Sincerely, BRS/CMA/mh
