Dear Mr. Crane:

By letter to the Nuclear Regulatory Commission (NRC) dated July 21, 2006, you submitted anaffidavit dated July 20, 2006, executed by J. A. Gresham, Manager, Regulatory Compliance and Plant Licensing, Westinghouse Electric Company, requesting that the information contained in the following document be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Part 2, Section 2.390:NF-BEX-06-167, Rev. 2 P-Attachment, ?Dresden Unit 3 Cycle 20 SLMCPR" A nonproprietary copy of this document has been placed in the NRC's Public Document Roomand added to the Agencywide Documents Access and Management System Public Electronic Reading Room.The affidavit stated that the submitted information should be considered exempt frommandatory 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 hiscompetitive 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 of10 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 version of the submitted information marked as proprietary will be withheld frompublic disclosure pursuant to 10 CFR 2.390(b)(5) and Section 103(b) of the Atomic Energy Act of 1954, as amended.
