Dear Sir or Madam:

By letter dated September 17, 2012 (Reference 3), Entergy Nuclear Operations, Inc.

(Entergy) replied to the violations issued in Reference 4 for Indian Point Nuclear Generating Unit No. 2 (IP2) and Unit No. 3 (IP3) for the use of unapproved operator manual actions (OMAs) to mitigate safe shutdown equipment malfunctions caused by a fire-induced single spurious actuation in lieu of protecting the equipment in accordance with 10 CFR Part 50 Appendix R, Paragraph III.G.2. The violations resulted from the denial of a number of OMAs in the Exemptions transmitted by letters dated February 1, 2012 (References 5 and 6). A revised response to the NOV was transmitted by letter dated December 7, 2012 (Reference 2). By letter dated May 2, 2013, a status update of the Planned Resolutions for the unapproved OMAs was provided. herein provides the status update of the Planned Resolutions for the unapproved OMAs for IP2, which was last provided in Attachment 2 in Reference 2, as follows:

The "Scheduled Completion Date" for OMAs 5, 6, 9, 10, 20 and 21 in all applicable Fire Areas/Fire Zones is now "Completed" (previously "Spring 2014 RFO") as the Planned Resolutions were completed during or following the Spring 2014 RFO. Note that the physical work for resolution of OMA 6 in Fire Zones 6, 7A, 22A and 27A of Fire Area F was completed on April 25 following the Spring 2014 RFO. The full resolution of this OMA required the construction of a fire-rated enclosure around valve LCV-1 12C. Branch Chief John Rogge was notified on March 17, 2014 that this enclosure modification would be completed online following the RFO.

As previously reported in Reference 2, the Planned Resolutions for all of the IP3 unapproved OMAs are complete. Attachment 2 provides the status as previously reported in Reference 2.

There are no new commitments contained in this letter. In the event of any questions, please contact Mr. Robert W. Walpole, Manager, Licensing at 914-254-6710.

Sincerely, JAV/gd
