Denton, Director Office of Nuclear Reactor Regulation Attn: A. Schwencer, Acting Chief Licensing Branch 83 Division of Licensing Office of Nuclear Reactor Regulation US NRC Washington, D.C. 20555 APPLICATION FOR WITHHOLDING PROPRIETARY INFORMATION FROM PUBLIC DISCLOSURE

SUBJECT:

Pacific Gas 8 Electric Co.

Diablo Canyon 1 Docket $ 50-275 Diablo Canyon 2 Docket 850-323 Turbine Disc Material Properties

Dear Mr. Schwencer:

This application for withholding is submitted by Westinghouse Electric Corporation ("Westinghouse" ) pusuant to the provisions of paragraph (b)

(1) of Section 2.790 of the Commission's regulations. Withholding from public disclosure is requested with respect to the subject information which is further identified in the affidavit accompanying this appli-cation.

The under signed has reviewed the information sought to be withheld and is authorized to apply for its withholding on behalf of Westinghouse, STG.

The affidavit accompanying this application sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of Section 2.790 of the Commission's regulations; Correspondence with respect to this application for withholding or the accompanying affidavit should be addressed to the undersigned.

R. W. Gaul Low Pressure Disc Task Force 4C0401a

Ref: AW-80-29 (1) I am Manager, in the Steam Turbine Generator Division of Westing-house Electric Corporation 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 am authorized to apply for its withholding on behalf of the Westinghouse Power Generation Divi-sions.

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

(3) I have personal knowledge of the criteria and procedures utilized by Westinghouse Power Generation Divisions in designating informa-tion as a trade secret, privileged or as confidential commercial or fi nanc i al i nf ormati on.

(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.790 of the Commission s regulations, the following is furnished for con-.

.sideration by the Commission in determi ning 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) 9...

The information is of by Westinghouse and a

8.

type customarily held in confidence 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 sub-stance of that system constitutes Westinghouse policy and provides the rational basis required.

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 compet-itive 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 consti-tutes 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 competitive economic advantage, e.g., by optimization, or improved marketability.

(c Its use by a competitor would reduce his expenditure or 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 capac-ities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.

(e) It reveals aspects of past, present, or future Westing-house or customer funded development plans and programs of potential commercial value to Westinghouse.

(f) It contains patentable ideas, for which patent protec-tion may be desirable.

(g) It is not the property of Westinghouse, but must be treated as proprietary by Westinghouse according to agreements with the owner.

(h) Public disclosure of this information would allow unfair and untruthful judgments on the performance and reliability of Westinghouse equipment components and improper comparison with similar components made by competitors.

There are sound policy reasons behind the Westinghouse system which include the following:

(a) The use of such information by Westinghouse gives Westinghouse a. competitive advantage over its competi-tors. 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 infor-mation.

(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 com-petitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advan-tage.

1 (9 Unrestricted disclosure wou1opardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition in those countries.

(f) The Westinghouse capacity to invest corporate assets in research and maintaining a competitive advantage.

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

(iv) The information is not available in public sources 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 as Enclosure 1 to letter from Phillip A. Crane to Schwencer, dated October 8, 1980 concerning information in response to NRC request for information relative to low pressure turbine disc integrity.

The information enables Westinghouse to:

(a) Develop test inputs and procedures to satisfactorily verify the design of Westinghouse supplied equipment.

(b Assist its customers to obtain icenses.

Further, the information has substantial commercial value as foll ows:

(a) Westinghouse can sell the use of this information to customers.

(b) Westinghouse uses the information to verify the design of equipment which is sold to customers.

(c) Westinghouse can sell services based upon the exper-ience gained and the test equipment and methods devel-oped.

Public disclosure of this information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to design, manufacture, verify, and sell electrical equipment for commercial turbine-generators without commensurate expenses. Also, public disclosure of the information would enable others having the same or similar equipment to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the infor-mation.

~ l U 4-

9 The development 6.

of the equipment described in part by the information is the result of many years of development by Westinghouse and the expenditure of a considerable sum of money.

This could only be duplicated by a competitor if he were to invest similar sums of money and provided he had the appro-priate talent available and could somehow obtain the requi-site experience Further the deponent sayeth not.
