Gresham, ManagerRegulatory ComplianceSworn to and subscribed before methis 7th day of March 2013NotaaPbiCOMMONWEALTH OF PENNSYLVANIA.. NOTARIAL SEALRenee Giampole, Notary Public IPenn Township, Westmoreland CountyMy Commission Expires , 2013J 2CAW-13-3642(1) I am Manager, Regulatory Compliance, in Nuclear Services, Westinghouse ElectricCompany LLC (Westinghouse), and as such, I have been specifically delegated the function ofreviewing the proprietary information sought to be withheld from public disclosure in connectionwith nuclear power plant licensing and rule making proceedings, and am authorized to apply forits withholding on behalf of Westinghouse.(2) I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of theCommission's regulations and in conjunction with the Westinghouse Application for WithholdingProprietary Information from Public Disclosure accompanying this Affidavit.'(3) I have personal knowledge of the criteria and procedures utilized by Westinghouse in designatinginformation as a trade secret, privileged or as confidential commercial or financial information.(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of the Commission's regulations,the following is furnished for consideration by the Commission in determining whether theinformation sought to be withheld from public disclosure should be withheld.(i) The information sought to be withheld from public disclosure is owned and has been heldin confidence by Westinghouse.(ii) The information is of a type customarily held in confidence by Westinghouse and notcustomarily disclosed to the public. Westinghouse has a rational basis for determiningthe types of information customarily held in confidence by it and, in that connection,utilizes a system to determine when and whether to hold certain types of information inconfidence. The application of that system and the substance of that system constitutesWestinghouse policy and provides the rational basis required.Under that system, information is held in confidence if it falls in one or more of severaltypes, the release of which might result in the loss of an existing or potential competitiveadvantage, as follows:(a) The information reveals the distinguishing aspects of a process (or component,structure, tool, method, etc.) where prevention of its use by any of 3CAW-13-3642Westinghouse's competitors without license from Westinghouse constitutes acompetitive economic advantage over other companies.(b) It consists of supporting data, including test data, relative to a process (orcomponent, structure, tool, method, etc.), the application of which data secures acompetitive economic advantage, e.g., by optimization or improvedmarketability.(c) Its use by a competitor would reduce his expenditure of resources or improve hiscompetitive position in the design, manufacture, shipment, installation, assuranceof quality, or licensing a similar product.(d) It reveals cost or price information, production capacities, budget levels, orcommercial strategies of Westinghouse, its customers or suppliers.(e) It reveals aspects of past, present, or future Westinghouse or customer fundeddevelopment plans and programs of potential commercial value to Westinghouse.(f) It contains patentable ideas, for which patent protection may be desirable.There are sound policy reasons behind the Westinghouse system which include thefollowing:(a) The use of such information by Westinghouse gives Westinghouse a competitiveadvantage over its competitors. It is, therefore, withheld from disclosure toprotect the Westinghouse competitive position.(b) It is information that is marketable in many ways. The extent to which suchinformation is available to competitors diminishes the Westinghouse ability tosell products and services involving the use of the information.(c) Use by our competitor would put Westinghouse at a competitive disadvantage byreducing his expenditure of resources at our expense.

CAW-13-3642(d) Each component of proprietary information pertinent to a particular competitiveadvantage is potentially as valuable as the total competitive advantage. Ifcompetitors acquire components of proprietary information, any one componentmay be the key to the entire puzzle, thereby depriving Westinghouse of acompetitive advantage.(e) Unrestricted disclosure would jeopardize the position of prominence ofWestinghouse in the world market, and thereby give a market advantage to thecompetition of those countries.(f) The Westinghouse capacity to invest corporate assets in research anddevelopment depends upon the success in obtaining and maintaining acompetitive advantage.(iii) The information is being transmitted to the Commission in confidence and, under theprovisions of 10 CFR Section 2.390, it is to be received in confidence by theCommission.(iv) The information sought to be protected is not available in public sources or availableinformation has not been previously employed in the same original manner or method tothe best of our knowledge and belief.(v) The proprietary information sought to be withheld in this submittal is that which isappropriately marked in LTR-A&SA-13-2 P-Attachment, Revision 1, "MonticelloReplacement Steam Dryer RAI Responses for Acoustic/Structural Analyses Set #2"(Proprietary), for submittal to the Commission, being transmitted by Xcel Energy letterand Application for Withholding Proprietary Information from Public Disclosure, to theDocument Control Desk. The proprietary information as submitted by Westinghouse isthat associated with the Monticello Replacement Steam Dryer Project, and may be usedonly for that purpose.

5CAW-13-3642This information is part of that which will enable Westinghouse to:(a) Provide Westinghouse recommendations related to the new steam dryerinspection following operation at EPU conditions presently scheduled for Spring2015.Further this information has substantial commercial value as follows:(a) Westinghouse plans to sell the use of the information to its customers for thepurpose of the Monticello Replacement Steam Dryer Project.(b) The information requested to be withheld reveals the distinguishing aspects of amethodology which was developed by Westinghouse.Public disclosure of this proprietary information is likely to cause substantial harm to thecompetitive position of Westinghouse because it would enhance the ability ofcompetitors to provide similar technical evaluation justifications and licensing defenseservices for commercial power reactors without commensurate expenses. Also, publicdisclosure of the information would enable others to use the information to meet NRCrequirements for licensing documentation without purchasing the right to use theinformation.The development of the technology described in part by the information is the result ofapplying the results of many years of experience in an intensive Westinghouse effort andthe expenditure of a considerable sum of money.In order for competitors of Westinghouse to duplicate this information, similar technicalprograms would have to be performed and a significant manpower effort, having therequisite talent and experience, would have to be expended.Further the deponent sayeth not.
