COUNTY OF BENTON I,, G. N, Ward being duly sworn, hereby say and depose:

1. I am Manager, Reload Licensing Liaison 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.

3. I am familiar with the document XN-NF-85-64(P) entitled "Plant Transient Analysis for D. C. Cook Unit 2 with 10 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 confidential 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 proprietary and confidential.

2

5. The Document has been made available to the U.S. Nuclear Regulatory Commission in conFidence, with the request that the information contained in the Document will not be disclosed or

divulged,

6. The Document contains information which is vital to a competitive 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 the Exxon Nuclear plant transient methodology which secure competitive advantage to ENC for fuel design optimization and marketability, an'd includes information utilized by ENC in its business which affords ENC an opportunity to obtain a competitive advantage over its competitors 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 the Exxon Nuclear plant transient methodology 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.

11. 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 the Exxon Nuclear plant transient methodology developed by ENC over the past several years. ENC has invested millions of dollars and many man-years of effort in developing the the Exxon Nuclear plant transient methodology 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.
