Dear Sir or Madam:

On March 12, 2012, the NRC issued Reference ito all power reactor licensees.

Enclosures 2 and 4 of Reference 1 contain specific requested actions, requested information, and required responses associated with Recommendations 2.1 and 2.3 for flooding evaluations and walkdowns. This letter provides the Entergy Nuclear

PNP 2012-049 Page 2 Operations, Inc. (ENO) 90-day response to Reference 1 for Palisades Nuclear Plant (PNP).

Recommendation 2.1: Flooding The response date for the PNP flood hazard evaluation was identified in Reference 2 as March 12, 2015, which corresponds to three years from the date of Reference 1.

ENO plans to meet the requested date for the other required responses in Enclosure 2 of Reference 1. Specifically, an approach for developing an Integrated Assessment for PNP will be submitted 60 days after the NRC endorses the Integrated Assessment Guidance. In addition, an Integrated Assessment report for PNP, if it is necessary, will be submitted two years after the flood evaluation is submitted.

Recommendation 2.3: Flooding For flooding Recommendation 2.3 (walkdowns), Enclosure 4 of Reference 1 states that each licensee is to confirm that it will use the NRC-endorsed flooding walkdown procedure or provide a description of the process it will use. ENO confirms that it will use the flooding walkdown procedure (NEI 12-07, Guidelines for Performing Verification Walkdowns of Plant Flood Protection Features) endorsed by Reference 3 as the basis for the flooding walkdowns at PNP.

ENO plans to comply with the response timeline in Enclosure 4 of Reference 1.

Specifically, ENO will submit a report documenting the results of its flooding design basis walkdowns at PNP by November 27, 2012, which corresponds to 180 days after NRC endorsement of the generic guidance.

The commitments contained in this submittal are summarized in Attachment 1.

I declare under penalty of perjury that the foregoing is true and correct. Executed on June 8, 2012.
