SUBJECT:

REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE l

Dear Mr. Kingsley:

! By letter from Commonwealth Edison Company (Comed) dated October 16,1998, and General ,

Electric Company's (GE) affidavit executed by David J. Robare, dated September 8,1998, you  !

i submitted a proprietary document entitled," ARTS Improvement Program Analysis for LaSalle  :

County Nuclear Station, Units 1 and 2, Removal of Direct Scram Bypassed Limits," GE-NEDC-31531P, Supplement 1, dated September 1998 and requested that it be withheld from public disclosure pursuant to 10 CFR 2.790. A non-proprietary version was also included in the submittal. i l'

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

"(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 ,

without license from General Electric constitutes a competitive economic advantage over other companies; I

(4)b Information which, if used 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 of a similar product; i (8) The information identified in paragraph (2), above, [ ARTS Improvement Program Analysis for LaSalle County Nuclear Station, Units 1 and 2, Removal of Direct

' Scram Bypassed Limits, GE-NEDC-31531P, Supplement 1, dated September i 1998] is classified as proprietary because it contains detailed results of analytical ,

models, methods and processes, including computer codes, which GE has developed, obtained NRC approval of, and applied to perform evaluations of the loss-of-coolant accidents and transients for the BWR. The development and approval of the BWR loss-of-coolant accident and transient analysis computer codes used in this analysis was achieved at a significant cost, on the order of f several million dollars, to GE.

1 0:0019 The deveiopment of the evaiuation process aions with the interpretation and l application of the analytical results is derived from the extensive experience ,

database that constitutes a major GE asset." g g 9812070115 981202 i PDR ADOCK 05000373 P PDR g M fit DENTER COPY
