(1) 1 am. Manager, Licensing ProDrams, in the Pressurized Water Rea.ctor s - .
. Systems Division, of Westinghouse Electric Corporation and is such, I have been specifically delegated the function of reviewing the proprietary information sought to.be withheld from public dis- .
closure in connection with nuclear power plant licensing or rule-
. making proceedings, and am authorized to apply for Hs withholding
. ' on behalf of the Westinghouse Water P.eactor Di .'ision1. .
__- (2) I' am making this Affidavit in conformance with the pryvisions of 10 CFR'Section 2.790 of the Comission's regulations and in con- -
junction with the kestinghouse application for withholding ac- ,
companying this Affidavit. , ,
. (3) I have personal knowledge of the criteria and procedures utilized by Westinghouse lluclear, Energy Systems in designating inforcation ,
as a trade secret, privileged or as confidential commercial or financial information. . '. .
(4) Pursuant to the. provisions of paragraph (b)(4) of Section 2.790 of the Co. nission's' regulations, the following is furn,ished for
~
consideration by the Cc=aission in determining whether the in-
- formation 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. .

. .. Attachment 2 -
. Mi-77-1S (ii) The information is of a type customarily held in configoce.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 ir) formation in confidence. The ap-
~ -
,' plication 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 more of several types, the release of which .
might result in the loss of an existing or potential com-
' ' ~ ' petitive' advantage, as 'follows:, ,
(a) The information reveals the di,stinguishing aspects of a ,
process (orcomponent 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 cons'ists of $upporting 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. .

AW-77-13 (c) Its use by a. competitor would reduce his expendiTuhe -
of resources or improve his cor.,petitive position in the design, manufacture, shipm.ent, installation, assurance .
of quality, or licensing a similar product.
(d) It reveals cost or price information, production cap- '
, acities, budget levels, or commercial strategies of '
Westinghouse, its customers or suppliers. -
. * ' ' (e) . It reveals aspects of past present, or future West- .
.inghouse or customer funded development plans and' pro '
. granis of potential cornercial value to Westinghouse. -
s -
(f) It contains patentable ideas, for which patent pro-tection may be desirable. -
(g)
It is not the property of Westinghouse, but n:ust be - ,
treated as proprietary by Westinghouse according to
.- ,' agreeinents with the owner. ,
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 com- .
; petitors It is, therefore, withheld from disclosure l 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 Westinghouse at a
- .' competitive disadvantage by reducing his expenditure of resour'ce.s at our expense. .
. : .~ ,- . . .;. .
(d) Each component of proprietary information per'tinent -
to a particular competitive advantage is potentially as valuable as the total' competitive advantage. If
" ~ ' ' '
competitors acquire cocponents of proprietary infor- -
mation, any one component may be the key to the entire "
.. . puzzle, thereby depriving Westinghouse of a competit'ive '
.' advantage. .,
.(e) Unres'tricted disclosure would jeopardize the position of prominence of Westinghouse in the world market. ,
and the,reby give a market advantage to the competition in 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.

position of Westinghouse, taking in'to account the value oy .

and considering the ways in which the information could be
