e 4 AW-94-602 (1) I am Manager, Advanced Plant Safety and Licensing, in the Advanced Technology Business Area, of the Westinghouse 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 rulemaking proceedings, and am authorized to apply for its withholding on behalf of the Westinghouse Energy Systems Business Unit.

T

_ (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 Energy Systems Business Unit in designating information as a trade secret, privileged or as conDdential 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.

1 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:

1590A

. AW.94-602 (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 companics.

(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 productc i

(d) It reveals cost or price information, production capacitics, 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 -

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 1

sell pnx!ucts and services involving the use of ibe information. l ima ,

l 1

4 AW-91602 '

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

(d) Each component of proprietary information pertinent to a particular competitive advantage is potentially a:; 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 Letter NTD-NRC-94-4081, March 21,1994, being transmitted by Westinghouse Electric Corporation (20 letter and Application for Withholding Proprietary Information from Public Disclosure, N. J. Liparulo (20, 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.

1590A

y AW-94-602 <

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.

(d) Establish technical and licensing approaches for the AP600 that will ultimately result in a certified design.

(e) Assist customers in obtaining NRC approval for future plants.

Further this information has substantial commercial value as follows: s 7

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

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

i competitors to provide similar advanced nuclear power designs 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 -

informhtion.- y 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, 1590A s

drwne/cetVO(Tamara OBJECTIVE:

for modeling the CMT Test in Detail with the COBRA (3D) Vessel Component of WCOBRA/ TRAC :

o Gain insight into thermal / hydraulic phenomena occurring within the CMT.

o Assess the degree of complexity needed to sufficiently model CMT.

o Develop an approach to use simpler models -

(TRAL component and NOTRUMP) for plant analyses.

o Help develop scaling rational for CMT.

CONCLUSIONS

. COARSE NODING USED IN NOTRUMP CAPTURES THE KEY THERMAL-HYDRAULIC BEHAVIOR IMPORTANT FOR PWR ANALYSIS RAPID CONDENSATION - -> STEAM FLOW DELAY IN INJECTION HEATUP OF UPPER NODE

- BASIS FOR THERMAL-HYDRAULIC PROCESSES WERE SHOWN IN MORE DETAILED CALCULATIONS

- TWO STEP APPROACH:

MORE DETAILED CALCULATIONS FOR UNDERSTANDING SIMPLER MODELS FOR PLANT ANALYSIS

- APPROACH WILL BE VERIFIED WITH INTEGRAL TESTS

'O INTEGRATION OF TEST / ANALYSIS FOR CMT OBJECTIVE IS TO USE THE CMT TEST TO DEVELOPNERIFY THE CMT MODELS IN NOTRUMP AND WCOBRA/ TRAC BOTH CODES WILL BE USED TO MODEL THE TESTS CODE-TO-CODE COMPARISONS WILL BE PERFORMED

+

TESTS WILL COVER ALL OPERATING MODES OF CMT USING THE FINAL MODELS FROM THE CMT TESTS; SPES SYSTEMS TESTS AND OSU SYSTEMS TESTS WILL BE ANALYZED BLIND TEST ANALYSES ARE PLANNED IF DEFICIENCIES EXIST, FOR THIS MODEL, THE ORIGINAL CMT TESTS WILL HAVE TO BE REINVESTIGATED THE INTENT IS TO NOT USE THE SPES OR OSU DATA TO ADJUST MODELS BUT TO USE THESE TESTS FOR VERIFICATION m:um
