==SUBJECT:==
Correction to a Previous Response Regarding the Unit 2 Auxiliary Feedwater Pump Room Fire Event Indian Point Nuclear Generating Unit Nos. 2 & 3 Docket Nos. 50-247 and 50-286 License Nos. DPR-26 and DPR-64

==REFERENCE:==
Entergy letter (NL-12-123)," Correction to Previous Responses Regarding Unit 1 Buried Piping and Unit 2 Auxiliary Feedwater Pump Room Fire Event," dated September 26, 2012

==Dear Sir or Madam:==

Entergy Nuclear Operations, Inc. is providing changes to the response provided by the referenced letter (NL-12-123). Entergy has determined that portions of the Unit 2 Instrument Air System previously credited for performing functions in the scope of license renewal and identified as subject to aging management review (AMR) are buried in soil but were not identified as buried in the referenced letter. This omission requires limited revisions to an AMR table for the Auxiliary Feedwater Pump Room Fire Event and Appendices A and B of the License Renewal Application (LRA), as identified in the attachment. In addition, the attachment identifies changes made to clarify that titanium components are included in the One-Time Inspection Program. The changes are consistent with the One-Time Inspection Program described in LRA Section B.1.27.
If you have any questions, or require additional information, please contact Mr. Robert Walpole at 914-254-6710.
I declare   nd r penalty of perjury that the foregoing is true and correct. Executed on Sincerel FRD/rw

Docket Nos. 50-247 & 50-286 NL-13-093 Attachment Page 1 of 3 The following are changes to the LRA determined necessary during review of completed buried piping inspections. One line item is added to aging management review table 3.4.2-5-7-1P2.
The change to Appendix A adds copper alloy to the list of relevant materials. The change to Appendix B adds the instrument air system to the list of systems to which the program applies.
Additions are underlined.

Preventive measures are in accordance with standard industry practice for maintaining external coatings and wrappings. Buried components are inspected when excavated during maintenance. If trending within the corrective action program identifies susceptible locations, the areas with a history of corrosion problems are evaluated for the need for additional inspection, alternate coating, or replacement.
B.1.6 BURIED PIPING AND TANKS INSPECTION Program Description The Buried Piping and Tanks Inspection Program is a new program that includes (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the pressure-retaining capability of buried and underground carbon steel, gray cast iron, copper alloy and stainless steel components. Preventive measures are in accordance with standard industry practice for maintaining external coatings and wrappings. Buried components are inspected when excavated during maintenance. If trending within the corrective action program identifies susceptible locations, the areas with a history of corrosion problems are evaluated for the need for additional inspection, alternate coating, or replacement. The program applies to buried components in the following systems.
