'AW-93-558 J (1) I am Manager, Advanced Plant Safety and Licensing, in the Nuclear Technology Division, of the Westinghouse Electric Corporation and as such, I have been specifically delegated thc

. function of reviewing the proprietary information sought to be withheld from public disclosure - -1 in connection with nuclear power plani licensi.ig and rulemaking proceedings, and am ,

authorized to apply for its withholding on behalf of the Westinghouse Energy Systems Business Unit.

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

I have perstmal knowledge of the criteria and procedures utilized by the Westinghouse Energy I (3)

Systems Business Unit in designating information as a trade secret, privileged or as ,

confidential commercial or financial information. ,

r (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 .f the types of information customarily held in confidence by it and, in that connection,  :

3 utilizes a system to determine when and whether to hold certain types of information ;

t in confidence. The application of that system and the substance 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 rnore of  ;

several types, the release of which might result in the loss of an existing or potential  ;

competitive advantage, as follows:

P P

4 1416A i

. . ~ . .

(

AW-93-558 I

(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:

(a) The use of such information by Westinghouse gives Westinghouse a l 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.

1416A

AW-93-558 (c) Use by our competitor would put Westinghouse at a competitive disadvantage, by reducing his expenditure of resources at our expense.

6

-(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.

(c) 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.

(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) Enclosed is 12tter ET-NRC-93-4032, December 22,1993, being transmitted by Westinghouse Electric Corporation (20 letter and Application for Withholding Proprietary Information from Public Disclosure, N. J. Liparulo (%_'), to Mr. R. W. Borchardt, Office of NRR. The proprietary information as submitted for use by Westinghouse Electric Corporation is in response to questions concerning the

  • AP600 plant and the associated design certification application and is expected to be-applicable in other licensee submittals in response to certain NRC requirements for justification of licensing advanced nuclear power plant designs.

1416A L-

AW-93-558 .

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

(a) Demonstrate the design and safety of the AP600 Passive Safety Systems.

(b) Establish applicable verification testing methods.-

(c) Design Advanced Nuclear Power Plants that meet NRC requirements.

Establish technical and licensing approaches for the AP600 that will ultimately'  :

(d) result in a certified design.

4 (c) Assist customers in obtaining NRC approval for future plants. ,

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 advanced plant licenses, t

(b) Westinghouse can sell support and defense of the technology to its customers in the licensing process.

Public disclosure of this proprietary information is likely to cause substantial harrn to the competitive position of Westinghouse because it would enhance the ability of-competitor to provide similar advanced nuclear power designs and licensing defense-services for commercial power reactors without commensurate expensesc 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 analytical methods and receiving NRC approval for those methods.-

AP600 Test Status - Staff Interactions

. o- December 10th meeting was held to discuss staff concerns with the AP600 test program

- Staff letter delineating specific test issues were addressed Many of the staff concerns resulted in a request or recommendation for additional

testing, either requidng:new facilities or expansion of the existing test matrices-

- Actions were developed to resolve the staff requests for additional tests by:

1) Evaluating the possibio thermal / hydraulic phenomenon that may occur during the plahi event in question ,
2) Reviewing existing analysis, then performing additional analysis if needed 1
3) Evaluating if the phenomenon of interest is already covered in existing tests ,
4) Determine what, if any, tests need to be considered in and what is the impact of those tests on the AP600 Certification schedule ,

- . After this process is complete, Westinghouse .will provide it's technical position' to the .

staff, which may or may not include additional testingi
