==Dear Sir or Madam:==

By         Reference           1, Indiana       Michigan      Power     Company       (I&M),   licensee        for the Donald C. Cook Nuclear Plant (CNP) Units 1 and 2, proposed to amend Appendix A, Technical Specifications, for the Unit 2 Facility Operating License, DPR-74.                         I&M requested Nuclear Regulatory Commission (NRC) approval to adopt a new analysis for the injection phase of a postulated large-break loss-of-coolant accident (LBLOCA) for CNP Unit 2, and proposed to modify the associated Technical Specifications. In a telephone discussion with members of the NRC staff on March 7, 2011, I&M committed to perform an updated analysis of the potential for boric acid precipitation to occur during the recirculation phase of a postulated LBLOCA, and transmit a summary of the analysis to the NRC no later than June 30, 2011. Reference 2 documented that commitment. This letter provides a summary report of the updated boron precipitation analysis per the commitment.

CAW-I 1-3188 AFFIDAVIT COMMONWEALTH OF PENNSYLVANIA:
ss COUNTY OF BUTLER:
Before me, the undersigned authority, personally appeared J. A. Gresham, who, being by me duly sworn according to law, deposes and says that he is authorized to execute this Affidavit on behalf of Westinghouse Electric Company LLC (Westinghouse), and that the averments of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief:
                                                          /J.A.Greghamr CoManager Regulatory Compliance Sworn to and subscribed before me this 13th day of June 2011 COMMONWEALTH OF PENNSYLVANIA Notarial Seal Cynthia Olesky, Notary Pubfic Manor Boro, Westmoreland County My Commission Expires July 16, 2014 Member. Pennsylvania Association or Notaries

2                                     CAW- 11-3188 (1) 1 am Manager, Regulatory Compliance, in Nuclear Services, Westinghouse Electric Company LLC (Westinghouse), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of Westinghouse.
(2) I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Commission's regulations and in conjunctionwith the Westinghouse Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.
(3) I have personal knowledge of the criteria and procedures utilized by Westinghouse in designating information as a trade secret, privileged or as confidential commercial or financial information.
(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.390 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 should be withheld.
(i)      The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.
(ii)     The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse 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 application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.
Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows:
(a)      The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of

3                                       CAW- 11-3188 Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.
(b)     It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.
(c)     Its use 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 a similar product.
(d)     It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.
(e)     It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.
(f)     It contains patentable ideas, for which patent protection may be desirable.
There are sound policy reasons behind the Westinghouse system which include the following:
(a)     The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors. It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.
(b)     It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.
(c)     Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.

4                                     CAW- 11-3188 (d)     Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage. If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.
(e)      Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.
(f)      The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.
(iii) The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Section 2.390; it is to be received in confidence by the Commission.
(iv)  The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.
(v)   The proprietary information sought to be withheld in this submittal is that which is appropriately marked in "D. C. Cook Unit 2 Post-LOCA Long Term Cooling Boron Precipitation Reanalysis Licensing Report Text," (Proprietary) for submittal to the Commission, being transmitted by American Electric Power letter and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk. The proprietary information as submitted by Westinghouse is that associated with the NRC review of the D. C. Cook Unit 2 Best Estimate ASTRUM Large Break LOCA Reanalysis.

5                                      CAW-1 1-3188 This information is part of that which will enable Westinghouse to:
(a)      Assist the customer in obtaining NRC review of the D. C. Cook Unit 2 Best Estimate ASTRUM Large Break LOCA Reanalysis.
Further this information has substantial commercial value as follows:
(a)      Westinghouse plans to sell the use of this information to its customers for purposes of plant specific LOCA analysis for licensing basis applications.
(b)      Its use by a competitor would improve their competitive position in the design and licensing of a similar product for Best Estimate ASTRUM Large Break LOCA analyses.
(c)      The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by Westinghouse.
Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar calculations and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.
The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.
In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.
Further the deponent sayeth not.
