1 Agencywide Documents Access and Management System (ADAMS) Accession No. ML13044A662

M. Pacilio - 2 The NRC staff has reviewed your application and the material in accordance with the requirements of 10 CFR 2.390. Your February 13, 2013, letter included a copy of CSS 32 9193800-000, but did not include any of the other documents listed above. On the basis of the statements in the affidavit, the staff has determined that the information submitted with the February 13, 2013, letter sought to be withheld contains proprietary commercial information and should be withheld from public disclosure. However, the NRC staff cannot make a determination about the proprietary nature of the documents listed above which were not submitted with the February 13, 2013, letter. A determination regarding these other documents will be made if, and when, they are submitted.

Therefore, CSS 32-9193800-000, "Quad Cities Unit 2 Instrument Nozzle J-Groove Weld Flaw Evaluation Using Finite Element," dated December 2012, 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.

If you have any questions regarding this matter, I may be reached at 301-415-1380.

Sincerely, iJ,A I~
