SUBJECT:

PALO VERDE NUCLEAR GENERATING STATION -REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE (TAC NO. MF6083)

Dear Mr. Edington:

By letter dated July 15, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 15198A242), Arizona Public Service Company (APS, the licensee) submitted an affidavit dated July 10, 2015, executed by James A. Gresham, Manager, Regulatory Compliance, Westinghouse Electric Company LLC, requesting that the information contained in the following documents be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Part 2, Section 2.390: 1. L TR-ME-15-30-P, Revision 2, "ASME Code Section XI Reconciliation for Arizona Public Service (APS), Palo Verde Nuclear Generation Station (PVNGS) Unit 3 Replacement Instrument Nozzle" (Enclosure, Attachment 5 to the letter dated July 15, 2015) 2. CN-PAFM-15-20-P, Revision 2, "Palo Verde Unit 3 RCS Cold Leg Alloy 600 Small Bore Nozzle Repair Transient Stress and Fracture Mechanics Evaluation for One Cycle Operation" (Enclosure, Attachment 3 to the letter dated July 15, 2015) 3. TR-FSE-15-2-P, Revision 1, "Palo Verde Nuclear Generation Station Unit 3 Evaluation of Potential Loose Part-Reactor Coolant Pump Instrument Nozzle Weld Fragment" (Enclosure, Attachment 4 to the letter dated July 15, 2015) 4. CN-NPE-06-XXXX-03-P, Revision 1, "Plant X-Structural Evaluations of the RCP Pressure Tap Nozzles," Part 1 and 2 (Enclosure, Attachment 6 to the letter dated July 15, 2015) 5. CN-MRCDA-15-13-P, Revision 0, "Qualification of Palo Verde Unit 3 Reactor Coolant Pump Replacement Instrumentation Nozzle" (Enclosure, Attachment 2 to the letter dated July 15, 2015)

R. Edington The information is included in attachments to the Enclosure to APS's letter stated above (ADAMS Accession No. ML 15198A242).

A nonproprietary version for documents numbered 2, 3, and 5, stated above, were designated as attachments to the Enclosure to APS's additional letter dated July 15, 2015 (ADAMS Accession No. ML 15198A224), and these nonproprietary versions have been placed in the U.S. Nuclear Regulatory Commission's (NRC's) Public Document Room and added to ADAMS in the NRC Library at Accession Nos. ML 15198A226, ML 15198A227, and ML 15198A225, respectively.

The affidavit stated that the submitted information should be considered exempt from mandatory public disclosure for the following reasons: (a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies. (b) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product. We have reviewed your application and the material in accordance with the requirements of 10 CFR 2.390 and, on the basis of the statements in the affidavit, have determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure.

Therefore, the versions of the submitted information marked as proprietary, will be withheld from public disclosure pursuant to 10 CFR 2.390(b)(5) and Section 103(b) of the Atomic Energy Act of 1954, as amended. Withholding from public inspection shall not affect the right, if any, of persons properly and directly concerned to inspect the documents.

If the need arises, we may send copies of this information to our consultants working in this area. We will, of course, ensure that the consultants have signed the appropriate agreements for handling proprietary information.

If the basis for withholding this information from public inspection should change in the future such that the information could then be made available for public inspection, you should promptly notify the NRC. You also should understand that the NRC may have cause to review this determination in the future, for example, if the scope of a Freedom of Information Act request includes your information.

In all review situations, if the NRC makes a determination adverse to the above, you will be notified in advance of any public disclosure.

R. Edington If you have any questions regarding this matter, I may be reached at 301-415-5136.
