Cook Nuclear Plant Unit 2 Docket No. 50-316 License No. DPR-74 Transmittal of Supplemental Safety Analysis Report Supporting Cycle 4 Operation Mr. Darrell 6. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission 7920 Norfolk Avenue Bethesda, MD 20014 SUBJECT REPORT: XN-NF-82-37(P), Supplement 1, "D. C. Cook Unit 2 Cycle 4 Safety Analysis Report," dated September 1982

Dear Mr. Eisenhut:

This letter transmits twenty-five (25) copies of the subject sup-plemental report. This report provides additional analysis of steady-state thermal margins in the D. C. Cook Unit 2 nuclear plant during Cycle 4 operation using ENC's automated crossflow methodology. Indiana lt Michigan Electric Company will be referencing this report in correspondence with you regarding Cycle 4 operation.

Exxon Nuclear Company considers the information contained in the subject report to be proprietary. In accordance with the Commission's Regulation 10 CFR 2.790(b), the enclosed Affidavit executed by our Dr. Richard B. Stout provides the necessary information to support the withholding of this document from public disclosure.

Please contact Dr. Juan Castresana of American Electric Power Company, telephone (212) 440-9282, if you have questions or comments regarding this transmittal.

Sincerely, J,C.

AFF I DAVIT STATE OF Washington )

ss.

COUNTY OF Benton )

I, Richard B. Stout, being duly sworn, hereby say and depose:

1. I am Manager, Licensing and Safety Engineering, for Exxon Nuclear Company, Inc. ("ENC"), and as such I am authorized to execute this Affidavit.

2. I am familiar with ENC's detailed document control system and policies which govern the protection and control of information.

t

3. I am familiar with the document XN-NF-82-37(P), Supplement 1, entitled "D. C. Cook Unit 2 Cycle 4 Safety Analysis Report; Thermal Hydraulic Analysis," referred to as "Document." Information contained in this Document has been classified by ENC as proprietary in accordance with the control system and policies established by ENC for the control and protection of information.

4. The Document contains information of a proprietary and con-fidential nature and is of the type customarily held in confidence by ENC and not made available to the public. Based on my experience, I am aware that other companies regard information of the kind contained in the Document as being proprietary and confidential.

5. The Document has been made available to the United States Nuclear Regulatory Commission in confidence, with the request that the information contained in the Document not be disclosed or divulged.

1 1

F, 1

6. The Document contains information which is vital to a com-petitive advantage of ENC and would be helpful to competitors of ENC when competing with ENC.

7. The information contained in the Document is considered to be proprietary by ENC because it reveals certain distinguishing aspects of PWR thermal hydraulic analysis methods and results which secure competitive economic advantage to ENC for fuel design optimization and improved market-ability, and includes information utilized by ENC in its business which affords ENC an opportunity to obtain 'a competitive advantage over its com-petitors who do not or may not know or use the information contained in the Document.

8'. The disclosure of the proprietary information contained in the Document to a competitor would permit the competitor to reduce its expenditure of money and manpower and to improve its competitive position by giving it extremely valuable insights into PWR thermal hydraulic analysis methods and results, and would result in substantial harm to the competitive position of ENC.

9. The Document contains proprietary information which is held in confidence by ENC and is not available in public sources.

10. In accordance with ENC's policies governing the protection and control of information, proprietary information contained in the Document has been made available, on a limited basis, to others outside ENC only as required and under suitable agreement providing for non-disclosure and limited use of the information.

ll. ENC policy requires that proprietary information be kept in a secured file or area and distributed on a need-to-know basis.

12. This Document provides information which reveals PWR analysis methods and results developed by ENC over the past several years. ENC has invested hundreds of thousands of dollars and many man-years of effort in developing the analysis methods revealed in the Document. Assuming a competitor had available the same background data and incentives as ENC, the competitor might, at a minimum, develop the information for the same expenditure of manpower and money as ENC.

13. Based on my experience in the industry, I do not believe that the background data and incentives of ENC's competitors are sufficiently similar to the corresponding background data and incentives of ENC to reasonably expect such competitors would be in a position to duplicate ENC's proprietary information contained in the Document.

THAT the statements made hereinabove are, to the best of my knowledge, information, and belief, truthful and complete.

FURTHER AFFIANT SAYETH NOT.
