AEP.-Anericaýs Energy Partner

U.S. Nuclear Regulatory Commission AEP:NRC:2075-02 Page 2 By Reference 1, I&M proposed to amend Facility Operating Licenses DPR-58 and DPR-74 to address control room habitability issues at CNP Unit 1 and Unit 2. Reference 2 transmitted partial responses to an NRC request for additional information and to NRC concerns identified in telephone conferences regarding the proposed amendment. Reference 3 provided a supplement to the proposed amendment.

Reference 2 and Reference 3 contained information that was designated as proprietary to Westinghouse Electric Company LLC (Westinghouse). The information consisted of numerical values associated with the departure from nucleate boiling ratio during a reactor coolant pump locked rotor event. The proprietary aspects of the information were addressed in Reference 2 and Reference 3 as follows:

"* Attachment 4 to Reference 2 and Attachment 3 to Reference 3 contained proprietary information.

"* Attachment 5 to Reference 2 and Attachment 7 to Reference 3 provided Westinghouse applications, pursuant to 10 CFR 2.790, to withhold from public disclosure the proprietary information in Attachment 4 to Reference 2 and Attachment 3 to Reference 3, respectively.

"* Attachment 6 to Reference 2 and Attachment 8 to Reference 3 provided non-proprietary versions of Attachment 4 to Reference 2 and Attachment 3 to Reference 3, respectively.

It has been determined that portions of the information designated as proprietary in Attachment 4 to Reference 2, and Attachment 3 to Reference 3 should not have been so designated. In accordance with 10 CFR 2.790(c), I&M is withdrawing the above identified attachments and replacing them with revised versions. The revised attachments are enclosed with this letter. Note that a single application to withhold proprietary information from public disclosure serves as the revised application for both Reference 2 and Reference 3 (Attachments 5 and 7, respectively). I&M understands that the withdrawn information will be returned.

This supplement involves only the proprietary designation of previously submitted information. The information is not affected. This supplement does not alter the proposed amendment, and does not affect the validity of the original evaluation of significant hazards considerations performed in accordance with 10 CFR 50.92, as documented in Attachment 4 to Reference 1. The environmental assessment provided in Attachment 5 to Reference 1 also remains valid.

Before me, the undersigned authority, personally appeared H. A. Sepp, who, being by me duly sworn according to law, deposes and says that he is authorized to execute this Affidavit on behalf of Westinghouse Electric Company LLC ("Westinghouse"), and that the averments of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief:

2 CAW-02-1570 (1) 1 am Manager, Regulatory and Licensing Engineering, in Nuclear Services, Westinghouse Electric Company LLC ("Westinghouse"), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of the Westinghouse Electric Company LLC.

(2) I am making this Affidavit in conformance with the provisions of 10CFR Section 2.790 of the Commission's regulations and in conjunction with the Westinghouse application for withholding accompanying this Affidavit.

(3) I have personal knowledge of the criteria and procedures utilized by the Westinghouse Electric Company LLC in designating information as a trade secret, privileged or as confidential commercial or financial information.

(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.790 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information 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 held in confidence by Westinghouse.

(ii) The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse has a rational basis for determining the 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 in confidence. The application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.

/cm/0253S doc

3 CAW-02-1570 Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, 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 Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.

(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.

(c) 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.

(d) It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.

(e) It reveals aspects of past, present, or future Westinghouse or customer funded development 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 the following:

/cm/0253S doc

4 CAW-02-1570 (a) The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors. It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.

(b) It is information which is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.

(c) Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.

(d) Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage. If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.

(e) Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.

(f) The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.

(iii) The information is being transmitted to the Commission in confidence and, under the provisions of 10CFR Section 2.790, it is to be received in confidence by the Commission.

/cm/0253S doc

5 CAW-02-1570 (iv) The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.

(v) The proprietary information sought to be withheld in this submittal is that which is appropriately marked in letters LTR-ESI-02-165, Revision 1 (Proprietary),

November 2002 and CAA-02-96, Revision 3 (Proprietary), November 2002 for D. C. Cook Units 1 and 2 being transmitted by the American Electric Company letter and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk, Attention Mr. Samuel J. Collins. The proprietary information as submitted for use by American Electric Company for D. C. Cook Units 1 and 2 is expected to be applicable in other licensee submittals in response to certain NRC requests for information to support the locked rotor rods-in-DNB analysis for D. C. Cook Unit 1 or 2.

This information is part of that which will enable Westinghouse to:

(a) Justify no rods-in-DNB for the locked rotor analysis.

(b) Assist the customer to respond to NRC requests for information.

Further this information has substantial commercial value as follows:

(a) Westinghouse plans to sell the use of similar information to its customers for purposes of meeting NRC requirements for licensing documentation.

(b) Westinghouse can sell support and justification for no rods-in-DNB for the locked rotor analysis.

/cm/0253S doc

6 CAW-02-1570 Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar support documentation and licensing defense services for commercial power reactors without commensurate expenses.

Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.

The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.

In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended for developing testing and analytical methods and performing tests.

Further the deponent sayeth not.
