SUBJECT:

REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE I

Dear Mr. Kingsley:

By letter from Commonwealth Edison Company (Comed) dated October 26,1998, and General Electric Company's (GE) affidavit executed by David J. Robare dated September ~30,1998, you l submitted a proprietary document entitled, " Quad Cities Nuclear Power Station, Units 1 and 2, i' Containment Analysis for Long-Term NPSH Evaluation with ANS 5.1-1979 + 2 Sigma Decay Heat," GE-NE-T2300750-00-02-R1 and requested that it be withheld from public disclosure pursuant to 10 CFR 2.790.

GE stated that the information should be considered exempt from mandatory public disclosure for the following reasons:

I

"(4)a information that discloses a process, method, or apparatus, including supporting

! data and analyses, where prevention of its use by General Electric's competitors l without license from General Electric constitutes a competitive economic  ;

< advantage over other companies; j

( l L .(4)b information which, if used by a competitor, would reduce his expenditure of I resources or improve his competitive position in the design, manufacture, j_ shipment, installation, assurance of quality, or licensing of a similar product;  ;

(8) The information identified in paragraph (2), above, [ Quad Cities Nuclear Power l Station, Units 1 and 2, Containment Analysis for Long-Term NPSH Evaluation  !

with ANS 5.1-1979 + 2 Sigma Decay Heat) is classified as proprietary because it  !

contains detailed design bases and methods and processes regarding the use of l analytical models, including computer codes, which GE has developed or j modified, and applied to perform evaluations of containment pressurization and  !

heat transfer capability for loss.of-coolant accidents for the BWR. This detailed  !

level of information normally only is available for GE intemal use, is not supplied

even to our customers, and only is available for audit by customers and the i)  !

NRC. This information shows in specific detail the processes, codes and / \ O methods employed to perform the evaluations. Q j i

O. Kingsley December 2, 1998 The development and modification of this information and models for these BWR analysis computer codes was achieved at a significant cost, on the order of several hundred thousand dollars, to GE. I The development of the supporting processes, was at a significant additional cost to GE, in excess of a million dollars, over and above the large cost of developing the underlying individual proprietary report information."

We have reviewed your submittal and the material in accordance with the requirements of 10 CFR 2.790 and, on the basis of GE's statements, have determined that the submitted information sought to be withheld contains trade secrets or proprietary commercial information and should be withheld from public disclosure.

Therefore, we have determined that the documents entitled," Quad Cities Nuclear Power Station, Units 1 and 2, Containment Analysis for Long-Term NPSH Evaluation with ANS 5.1-1979 + 2 Sigma Decay Heat," 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.

1 Withholding from public inspection shall not affect the right, if any, of persons properly and directly concerned to inspect the document. If the need arises, we may send copies of this information to our consultants working in this area. We will, of course, insure that the  ;

consultants have signed the appropriate agreements for handling proprietary information.  !

If the basis for withholding this information from public inspection 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 also 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 information. In all review situations, if the NRC needs additional information from you or makes a determination adverse to the above, you will be notified in advance of any public disclosure.
