Dear Sir or Madam:

On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued Order EA-12-049, "Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events," which was immediately effective and directed Entergy Nuclear Operations, Inc. (ENO) to develop and implement strategies and guidance to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities in the event of a beyond-design-basis external event (Reference 1).

On December 16, 2015, ENO provided notification of full compliance with NRC Order EA-12-049 for the Palisades Nuclear Plant (PNP) (Reference 2). The letter included the Final Integrated Plan (FIP) for PNP. The FIP provided strategies to maintain or restore

PNP 2016-019 Page 2 of 2 core cooling, containment, and spent fuel pool cooling capabilities in the event of a beyond-design-basis external event at PNP.

A discrepancy has been discovered in the description of the on site FLEX portable diesel generators in the FIP. The FIP described the rating of the onsite FLEX portable diesel generators as 480 V, 500kVA, and 400 kW (standby rating). However, the ratings of the diesel generators actually selected are 480 V, 636 kVA, and 509 kW (standby rating),

and 480 V, 578 kVA, and 463 kW (prime rating). ENO plans to revise the FIP to reflect the prime rating of the selected diesel generators. This discrepancy appears on pages 16, 51, and 109 of the FIP. The discrepancy does not otherwise affect the strategy provided in the FIP.

This letter contains no new commitments and no revised commitments.

I declare under penalty of perjury that the foregoing is true and correct; executed on March 23, 2016.

Sincerely, cc: Office Director, NRR, USNRC Administrator, Region III, USNRC Project Manager, Palisades, USNRC Resident Inspector, Palisades, USNRC
