Attention: Mr. Darrell G. Eisenhut R:; ' N T Division of Licensing Mf 5 N U.S. Nuclear P.egulatory Commission =[' G Mi Washington, DC 20555 -s m 2 5 Docket 50-312 E Rancho Seco Nuclear Generating Station, Unit No. 1

Dear Mr. Eisenhut:

The purpose of this letter is to provide you with updated infor-mation in response to your reouest for information of February 25, 1980, relative to turbine disc integrity. Our original response dated March 19, 1980 contained the results of site-specific calculaticns, to respond to question 1-d of your letter. These calculations have now been repeated employing a more sophisticated calculational rodel, which now accounts for thermal and steam bending stresses, and a revised correlation for calcula-ting the crack growth rate. The results of these calculations are pre-sented in the attachments which constitute a revision to Enclosure 1 (proprietary) and Enclosure 1 (non-proprietary) of our previous submittal. The attached site specific resoonses (Enclosure 1) contain proori-Stary information of the Westinghouse Electric Corporation. A copy of the previously submitted Apolication for Withholding AH-80-5 dated March 11, 1980 and the associated affidavit is attached and is equally acclicable to this new material. Accordingly, it is recuested that the subject Westing-house proprietary infomation be withheld from public disclosure in accord-ance with the provisions of 10CFR2.790 of the Cormission's regulations. Corresoondence with resoect to the affidavit or acolication for withholding should reference AW-80-5 and should be addressed'to Mr. R. W. O/ Gaul, Manager, CR Disc Program, Westinghouse Electric Corporation, Steam 5 Turbine Division, Lester Branch Box 9175, Philadelphia, PA 19113. ll/ Sincerely yours, (/uJg: 6 t::: n 907 / .v.p W TC' M i n?

AW-80-5 March 14, 1980 Darrell G. Eisenhut Division of Operating Reactors Office of Nuclear Reactor Regulation US Nuclear Regulatory Commission Washington DC 20555 APPLICATION FOR WITHHOLDING PROPRIETARY INFORMATION FROM PUBLIC DISCLOSURE

Subject:

Rancho Seco Generating Station - Unit il Docket #50-312 Information in Response to NRC Request for Information of February 25, 1980, Relative to Low Pressure Turbine Dise Integrity.

Reference:

Appendix A letter from J. J. Mattinoe to Eisenhut, dated 3/19/80

Dear Mr. Eisenhut:

This application for withholding is submitted by Westinghouse Electric Corporation (" Westinghouse") pursuant to the provisions of paragraph (b)(1) of Section 2.790 of the Commission's regulations. Withholding from public disclosure is requested with raspect to the subject information which is further identified in the af fidavit accompanying this application. The undersigned has reviewed the information sought to we withheld and is authorized to apply for its withholding on behalf of Westinghouse, STG-TOD. The affidavit accompanying this application sets forth the basis on which the information may be withheld fren 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. Accordingly, it is respectfully requested that the subject information which is proprietary to Westinghouse and which is further identified in the af fi-davit be withheld from public disclosure in accordance with 10CFR Section l 2.790 of the Commission's regulations. Correspondence with respect to this application for withholding or the accom-panying affidavit should be addressed to the undersigned. Very truly yours, l l [Lk(hD o I-R. Williamson, Manager l l Cus tomer Order Engineering Westinghouse Electric Corporation l 1 =

Ref: AW-80-5 AFFIDAVIT COMMONWEALTH OF PENNSYLVANIA COUNTY OF DELAWARE: Before me, the undersigned authority, personally appeared Robert Williamson, who, being by me duly sworn according to law, deposes and cays that he is authorized to execute this Affidavit on behalf of L'estinghouse Electric Corporation (" Westinghouse") and that the avercents of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief: b .r Robert Williamson, Manager Customer Order Engineering twom 1: 4M Sa%~C'd ['*b" y), ,,,,,CSj d{?A!d N .R5 w [eWD .m HENRY E SQUILLACE hry Pid:ic. Harpre I"D. De aware Co. W Comtthen fagres Oct. 13.1940 e l ... ~

I am Manager, Customer Order Engineering in the Steam Turbine (1) Generator Tech'nical Operations Division of Westinghouse Electric Corporation and as such, I have been specifically delegated the function of reviewing the proprietary infor=ation sought to be withheld from public disclosure in connection with nuclear power plant licensing, and am authorized to apply for its withholding en behalf of the Westinghouse Power Generation Divisions. (2) I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.790 of the Com=ission'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 Westinghouse Power Generation Divisions in designating informa-tien as a trade secret, privileged or as confidential cec =ercial or financial information. Pursuant to the provisiens of par 3raph (b)(4) of Section 2.790 of (4) the Commission's regulations, the following is furnished for cen-sideratien by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld. (1) The information souFht to be withhald 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 pub-I lic. Westinghouse has a rational basis for determining the types of information customarily held in confidence by it in that connection, utilises a system to determine when I

and, f

and whether to hold certain types of information in confi-The application of that system and the substance of l dence. that system constitutes Westinghouse policy and provides the l rational basis required. O mm 7

D i Under that system, iafor=ation 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 er potential com-petitive 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-l i l 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, s method, etc.), the applicatien of which data secures a ecmpetitive economic advantage, e.g., by optimization ~or i=preved marketability. (c) Its use by a ec=petitor 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 capac-ities, budget levels, or ecmmercial strategies of West-inghouse, its custo=ers 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. v -, - - - -,-,,,,,. _,, - ---- --,--e--,._----,n--

a

(h) Puelic disclosure of this information would allow un-fair and untruthful judgments on the ; erformance and reliability of Westinghouse equipment components and improper comparison with similar co=ponents 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 West-inghouse 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 Westinghou:e at a com-petitivs 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 'r valuable as the total competitive advantage. If com-petitors acquire components of proprietary information, any one component may be the key to the entire pu::le, igt 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 in g,' those countries.

ym (f) The hestinghouse capacity to invest corporate assets in j/ research and development depends up,on the success in obtaining and maintaining a competitive advantage. ~ (i11) The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Sec-tion 2 790, it is to be received in confidence by the Cocmission. (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 in Appen-dix A to letter from J. J. Mattinoe to Eisenhut, dated March 19, 1980 concerning infor-mation in response to NRC request for information of February 25, 1980, 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 licenses. Further, the information has rubstantial commercial value as follows. (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 developed. 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 fcr commercial turbine-generators without commensurate Also, public disclosure of the information would expenses. enable others hcving the same or similar equipment to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information. The development 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 su=s of money and provided he had the appro-priate talent available and could somehow obtain the requi-site experience. Further the deponent sayeth not. l l .}}
