Mr. George W. Knighton, Branch Chief Licensing Branch No. 3 U. S. Nuclear Regulatory Commission Washington, D.C.

20555 Gentlemen:

Subject:

Docket Nos. 50-361 and 50-362 San Onofre Nuclear Generating Station Units 2 and 3 SCE met with the NRC Staff on June 29, 1984 in Bethesda, Maryland to discuss the following Core Protection Calculator (CPC) software and methodology changes which will be incorporated into Cycle 2 of SONGS Units 2 and 3:

o Minor Calculational and Constant Changes o

Enhancements to Thermal Margin o

CPC Performance Enhancement The algorithm changes which are being incorporated with the software changes revise ordinary data base constants to accommodate the Cycle 2 core design. In addition, certain methodology changesbeing introduced into the Cycle 2 analyses are evolutionary in nature and represent either small adjustments to the methodology used to calculate constants or small differences in the algorithms themselves and many of the modifications have already been implemented for CESSAR Plants.

The June 29, 1984 meeting focused primarily on SONGS Unit 2 because of the close proximity of the scheduled first refueling outage. It is expected that the SONGS Unit 2 Cycle 2 CPC changes will be identical to those changes for SONGS Unit 3 Cycle 2 and therefore all changes discussed are considered to be applicable to Cycle 2 operation for both Units 2 and 3.

Since much of the information presented during the June 29, 1984 meeting was proprietary in nature to Combustion Engineering Inc. (CE), the NRC staff was not able to retain copies of the handouts utilized. This letter formally transmits copies of (1) a report containing the June 29, 1984 meeting handouts and a summary of the presentation and (2) a report describing changes to the SONGS Units 2 and 3 CPC/CEAC software for Cycle 2 operation in order to facilitate early NRC notification of methodology and software changes.

SS.:

I, A. E. Scherer, depose and say that I am the Director, Nuclear Licensing, of Combustion Engineering, Inc., duly authorized to make this affidavit, and have reviewed or caused to have reviewed the information which is identified as proprietary and referenced in the paragraph immediately below. I am submitting this affidavit in conformance with the provisions of 10 CFR 2.790 of the Commission's regulations and in conjunction with the application of Southern California Edison Company for withholding this information.

The information for which proprietary treatment is sought is contained in the following document:

CEN-281 (S)-P, CPC/CEAC Software Modifications for San Onofre Nuclear Generating Station Units 2 and 3, June 1984.

This document has beenjappropriately designated as proprietary.

I have personal knowledge of the criteria and procedures utilized by Combustion Engineering in designating information as.a trade secret, privileged or as confidential commercial or financial information.

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, included in the above referenced document, should be withheld.

1 The information sought to be withheld from public disclosure are algorithm changes and data base constants for software modifications to the San Onofre CPC/CEAC System, which is owned and has been held in confidence by Combustion Engineering.

2. The information consists of test data or other similar data concerning a process, method or component, the application of which results in a substantial competitive advantage to Combustion Engineering.
3. The information is of a type customarily held in confidence by Combustion Engineering and not customarily disclosed to the public. Combustion Engineering 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 information in confidence. The details of the aforementioned system were provided to the Nuclear Regulatory Commission via letter DP-537 from F.M. Stern to Frank Schroeder dated December 2, 1974. This system was applied in determining that the subject document herein are proprietary.
4. The information is being transmitted to the Commission in confidence under the provisions of 10 CFR 2.790 with the understanding that it is to be received in confidence by the Commission.
5. The information, to the best of my knowledge and belief, is not available in public sources, and any disclosure to third parties has been made pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence.
6. Public disclosure of the information is likely to cause substantial harm to the competitive position of Combustion Engineering because:
a. A similar product is manufactured and sold by major pressurized water reactor competitors of Combustion Engineering.
b. Development of this information by C-E required tens of thousands of manhours of effort and hundreds of thousands of dollars. To the best of my knowledge and belief a competitor would have to undergo similar expense in generating equivalent information.
c. In order to acquire such information, a competitor would also require considerable time and inconvenience in developing algorithms and constants for the San Onofre CPC/CEAC system.
d. The information required significant effort and expense to obtain the licensing approvals necessary for application of the information.

Avoidance of this expense would decrease a competitor's cost in applying the information and marketing the product to which the information is applicable.

e. The information consists of algorithm changes and data base constants for software modifications to the San Onofre CPC/CEAC System, the application of which provides a competitive economic advantage.

The availability of such information to competitors would enable them to modify their product to better compete with Combustion Engineering, take marketing or other actions to improve their product's position or impair the position of Combustion Engineering's product, and avoid developing similar data and analyses in support of their processes, methods or apparatus.

f. In pricing Combustion Engineering's products and services, significant research, development, engineering, analytical, manufacturing, licensing, quality assurance and other costs and expenses must be included.

The ability of Combustion Engineering's competitors to utilize such information

without similar expenditure of resources may enable them to sell at prices reflecting significantly lower costs.

g. Use of the information by competitors in the international marketplace would increase their ability to market nuclear steam supply systems by reducing the costs associated with their technology development. In addition, disclosure would have an adverse economic impact on Combustion Engineering's potential for obtaining or maintaining foreign licensees.

Further the deponent sayeth not.
