9 AW-95-773 (1)

I am Manager, Advanced Plant Safety & 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.

l (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.

i (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 I

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.

l (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 cenain 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.

l 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:

i i

2244A

4 AW-95-773 (a)

The information reveals the distinguishing aspects of a process (or component, I

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 l

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 ccmpetitor would reduce his expenditure of resources or improve his competitive oosition in the design, manufacture, shipment, installation, l

I assurance of quahiy, or licensing a similar product.

l (d)

It reveals cost or price information, production capacities, budget levels, or commercial strategies of M estinghouse, its customers or suppliers.

(e)

It reveals aspects of past, present, or future Westinghouse or customer funded i

development plans and programs of potential commercial value to Westinghouse.

(f)

It contains patentable ideas, for which patent protection may be desirable, l

i There are sound policy reasons behind the Westinghouse system which include the I

following:

(a)

The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors. It is, therefore, withheld from l

l disclosure to protect the Westinghouse competitive position.

l l

l (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 l

sell products and services involving the use of the information.

22444 l

?'

..~. -.

.. ~

. ~_ -

t:

9 AW-95-773 (c)

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

i (d)

Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive r

advantage. If competitors acquire components of proprietary information, any I

one component may be the key to the entire puzzle, thereby depriving i

Westinghouse of a competitive advantage.

9 (e) linrestricted disclosure would jeopardize the position of prominence of l

Westinghouse in the world market, and thereby give a market advantage to the i

competition of those countries.

j (f)

The Westinghouse capacity to invest corporate assets in research and :

development depends upon the success in obtaining and maintaining a competitive advantage.

Ij (iii)

The information is being transmitted to the Commission in confidence and, under the i

provisions of 10CFR Section 2.790, it is to be received in confidence by the' Commission.

i i

i (iv)

The information sought to be protected is not available in public sources or available l

l information has not been previously employed in the same original manner or method i

to the best of our knowledge and belief.

(v)

Enclosed is Letter NTD-NRC-95-4387, January 13,1995 being transmitted by Westinghouse Electric Corporation (W) letter and Application for Withholding Proprietary Information from Public Disclosure, N. J. Liparulo (E, 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.

r i~

ma

AW-95-773 i

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

i l

l (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.

l (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:

l (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.

l 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 advanced nuclear power designs and licensing defense j

services for commercial power reactors without commensurate expenses. Also, public j

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 infonnation.

l 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 l

and the expenditure of a considerable sum of money.

i l

l 7244A

l t

l AW-95-773.

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.

Further the deponent sayeth not.

l Mixing characteristics of the 300 series tests There is an initial high steam flow period in which there is rapid condensation occurring at the steam diffuser i

The condensation induces a steam momentum flux which causes mixing of the subcooled CMT liquid which then enhances the condensation The liquid mixing depth was found to be dependent on the inlet steam momentum i

The mixing and rapid condensation ended suddenly while the bulk of the mixing layer was still subcooled The rapid condensation at the diffuser results in reduced CMT l

l-gr ng NOTRUMP CMT PRELIK VALIDATION REPORT NOTRUMP METHOD OF CALCULATION FOR AN INITIALLY FULL CMT If no vapor space exists in a node full of subcooled liquid, NOTRUMP will continue to condense steam until the ~ liquid is at or very near the saturation temperature (homogeneous mixing)

Once the liquid is saturated, the vapor can form a region in the cell and all i

subsequent vapor will flow to the vapor space A level can exist in a node with non-equilibrium between the liquid and the vapor phases. The interfacial heat transfer is then calculated by the code Since steam diffuser is submerged in CMT liquid, the homogeneous mixing approach is a reasonable,if not conservative, assumption Homogeneous mixing assumption does make the NOTRUMP CMT model l

noding dependent, judgement must be used Artificial thermal diffusion does exist in the NOTRUMP calculation as the hotter liquid flows between cells and mixes perfectly. This smooths the fluid axial temperature gradient in the CMT relative to the data. This is believed to have a small effect on the overall transient response

V'1 NOTRUMP CMT PRELIM. VALIDATION REPORT i

CONCL 3lONS Nusselt laminar film condensation for the CMT walls appears reasonable Most, if not all, small-break LOCA transients will have ample recirculation such that direct condensation effects would be minimized.

4 NOTRUMP homogeneous mixing modelling does not capture the steam momentum effects observed in the test data Current NOTRUMP homogeneous mixing model will over predict a delay in the CMT draining due to condensation if the CMT liquid is cold Use of the McAdams natural convection correlatior ' NOTRUMP will correctly predict the liquid to wall heat transfer The homogenous mixing n.cJet in NOTI (UMP is noding dependent, the SSAR CMT noding appears appropriate. OMT recirculation reduces th;s dependency since condensation is significantly reduced.

NOTRUMP CMT model will be further verified against SPES-2 and OSU data

ll!Fj NOTRUMP CMT PRELIK VALIDATION REPORT i

CONCLUSIONS Phenomena identified in the CMT scaling PIRT have been captured and analyzed Data has been analyzed and compared to the correlations used in the NOTRUMP code Tests have identified areas where modelling improvement will be used, use of Nusselt film correlation Tests have confirmed that the application of the current SSAR CMT noding is conservative
