SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE INDIAN POINT NUCLEAR GENERATING UNITS 2 AND 3, LICENSE RENEWAL APPLICATION, SET 2012-03 (TAC NOS. MD5407 AND MD5408)

Dear Sir or Madam:

By letter dated April 23, 2007, as supplemented by letters dated May 3,2007, and June 21,2007, Entergy Nuclear Operations, Inc. (Entergy or the applicant). submitted an application pursuant to Title 10 of the Code of Federal Regulations, Part 54, to renew the operating licenses for Indian Point Nuclear Generating Units 2 and 3, for review by the U.S.

Nuclear Regulatory Commission (NRC or the staff). The staff documented its findings in the Safety Evaluation Report (SER) related to the License Renewal of Indian Point Nuclear Generating Units 2 and 3, which was issued August 2009 and supplemented August 30,2011 (SER Supplement 1).

As part of its review of Entergy's "Indian Point Energy Center Reactor Vessel Internals Inspection Plan," the staff requested additional information by letter dated May 15, 2012.

Entergy responded by letter dated June 14, 2012. Since the issuance of that response, the staff has identified the need for additional information with respect to this plan and the associated Reactor Vessel Internals Inspection Program as described in the enclosure.

This request for additional information was discussed with Mr. Roger Waters, and a mutually agreeable date for Entergy's response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-3873, or via e-mail at John.Daily@nrc.gov.

Sincerely, John W. Daily, Sr. Project Mana er Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket Nos. 50-247 and 50-286

REQUESTS FOR ADDITIONAL INFORMATION, SET 2012-03 RELATED TO INDIAN POINT NUCLEAR GENERATING, UNITS 2 AND 3, LICENSE RENEWAL APPLICATION DOCKET NOS. 50-247 AND 50-286 REACTOR VESSEL INTERNALS PROGRAM (Set 2012*03)

RA.16 (RV' Components)

Entergy Nuclear Operations, Inc. (Entergy)'s response to Applicant/Licensee Action Item 3 in the Reactor Vessel Internal (RVI) Inspection Plan (Reference 1), indicates that the current Indian Point Unit 2 (IP2) guide tube support pins (split pins) were installed in 1995 and are fabricated from X750 Rev. B material, which has improved resistance to stress corrosion cracking (SCC). Entergy's response further states that it plans to begin preliminary IP2 split pin replacement engineering and walkdowns in 2014 and replace the split pins in 2016. However, no basis was given for these dates. The response to request for additional information (RAJ) 8 (Reference 2) indicates, in part, that no inspections are planned for the split pins during the period of extended operation, except that the replacement cold-worked Type 316 pins could potentially be inspected if determined to be necessary based on operating experience. Based on the above, the applicant apparently does not plan any inspections of the currently installed IP2 split pins.

Requested Information:

1. Justify the proposed date for replacement of the IP2 split pins, based on predicted degradation of the split pins, and considering that no inspections will be performed on the currently-installed pins prior to replacement.

2. If (a) the proposed replacement date (2016) cannot be justified without performing inspections; or (b) the currently-installed IP2 split pins are not replaced by the proposed date, provide the date when inspections would need to commence, and the periodicity of these inspections to ensure the intended function(s) of the split pins will be maintained until replacement.

3. Describe the inspection methods to be used for any inspections proposed.
