Dear Sir or Madam:
On March 12, 2012, the NRC issued Reference 1 to 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 Operations, Inc. (Entergy's) 90-day response to Reference 1 for Vermont Yankee (VY).
Recommendation 2.1: Floodinq The response date for VY's flood hazard evaluation was identified in Reference 2 as March 12, 2013 which corresponds to one year from the date of Reference 1.
Entergy 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 VY will be submitted 60 days after NRC endorsement of the Integrated Assessment Guidance. In addition, an Integrated Assessment report for VY, if it is necessary, will be submitted two years after the flood evaluation is submitted.

BVY 12-038 / Page 2 of 3 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. Entergy confirms that it will use the flooding walkdown procedure (Nuclear Energy Institute 12-07, Guidelines for Performing Verification Walkdowns of Plant Flood Protection Features) endorsed by Reference 3 as the basis for the flooding walkdowns at VY.
Entergy plans to comply with the response timeline in Enclosure 4 of Reference 1.
Specifically, Entergy will submit a report documenting the results of its flooding design basis walkdowns at VY by November 27, 2012, which corresponds to 180 days after NRC endorsement of the generic guidance.
The new commitments contained in this submittal are summarized in Attachment 1.
Should you have any questions regarding the content of this letter, please contact Mr.
