'f WASHINGTON, D.C. 20666-0001

\\.....,o8 June 19, 1998 I

i Mr. Brian A. McIntyre, Manager Advanced Plant Safety and Licensing Westinghouse Electric Company P.O. Box 355 Pittsburgh, PA 15230-0355

SUBJECT:

REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE FOR WESTINGHOUSE AP600 DESIGN LETTERS

Dear Mr. McIntyre:

Enclosed with this letter is a table of Westinghouse letters you have submitted which support the AP600 design certification. Specifically, the letters listed in the enclosed table respond to Nuclear Regulatory Commission (NRC) requests for additional information (RAls) on the AP600 design certification reactor systems test program and computer analyses codes - NOTRUMP, LOFTRAN, and WCOBRA/ TRAC. In addition, some of the letters in the table address information on hydrodynamic loading, long-term cooling, the SPES-2 facility description report, the PRHR final test report, and draft sections of the NOTRUMP final verification and validation report.

In these letters, you identify information which you consider proprietary and request that it be withheld from public disclosure pursuant to 10 CFR 2.790. The subject material is provided via

. enclosure to each letter in both a proprietary and nonproprietary form. Each letter is supported by an affidavit which claims, in part, that the information is classified as proprietary because "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 addition, the affidavits also state that this information should be considered exempt from mandatory public disclosure for the following reasons (as specifically noted on the enclosed table):

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.

. Mr. Brian A. McIntyre June 19, 1998

~

. We have reviewed your submittals and the material in accordance with the requirements of 10 CFR 2.790 and, on the basis of Westinghouse's statements, have' determined that the

. submitted information sought to be withheld contains trade secrets or proprietary commercial information.

5 Therefore, we have determined that th'e proprietary materials documented 'on the enclosed -

table, which when submitted to the NRC where marked as proprietary, will be withheld from

. public disclosure pursuant to 10 CFR 2.790(b)(5) and Section 103(b) of the Atomic Energy Act

. of 1954, as amended._

Withholding from public inspection shall not affect the right, if any, of persons properly and directly concemed to inspect the documents if the need arises, we may send copies of this -

information to our consultants working in this area. We will, of course, ensure that the '

. consultants have signed the appropriate agreements for handling propnetary information.

If the basis for withholding.this information from public disclosure should change in the future such that the information could then be made available for public inspection, you should promptly notify the NRC.' You should understand that the NRC may have cause to review this determination in the future, for example, if the scope of a Freedom of information Act request includes your withheld information. In all review situations, if the NRC makes a determination adverse to the above, you will be notified in advance of any public disclosure.

Sincerely, original signed by

William C. Huffman, Project Manager Standardization Project Directorate Division of Reactor Program Management Office of Nuclear Reactor Regulation Docket No.52-003
