10 CFR 2.390, "Public Inspections, Exemptions, Requests for Withholding."

I, Scott Greenhaus, am Executive Vice President of Structural Group, Inc. (SGI). In my capacity as Executive Vice President I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in conjunction with nuclear plant licensing and rulemaking proceedings and am authorized to apply for its withholding on behalf of SGI and its affiliates.

I am making this Affidavit in conformance with the provisions of 10 CFR 2.390 of the U. S.

Nuclear Regulatory Commission (USNRC) regulations and in conjunction with SGIs Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.

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

Pursuant to the provisions of paragraph (b)(4) of 10 CFR 2.390 of the USNRC's regulations, the following is furnished for consideration by the USNRC in determining whether the information sought to be withheld from public disclosure should be withheld.

The information provided by Exelon Generation Company, LLC to the NRC in the pre-submittal meeting scheduled for January 10, 2022 includes SGI proprietary information. The information sought to be withheld from public disclosure is owned by and has been held in confidence by SGI.

The information is of a type customarily held in confidence by SGI and not disclosed to the public. SGI has a rational basis for determining the types of information customarily held in confidence by it and 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 provides a rational basis for maintaining confidentiality and justifies the USNRC withholding the information from public disclosure.

Under SGIs 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:

1.

The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by a competitor of SGI without license constitutes a competitive advantage over other companies.

2.

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.

3.

Its use by a competitor would reduce their expenditure of resources or improve their competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.

4.

It reveals commercial strategies of SGI, their customers or suppliers.

5.

It reveals aspects of past, present, or future development plans funded by SGI or its customer, and programs of potential commercial value to SGI.

There are sound policy reasons behind the SGI system which include the following:

1.

The use of such information by SGI gives it a competitive advantage over competitors. It is, therefore, withheld from disclosure to protect SGI's competitive position.

2.

It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes SGIs ability to sell products and services involving the use of the information.

3.

Use by a competitor would put SGI at a competitive disadvantage by reducing the competitor's expenditure of resources and capital.

4.

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 process, thereby depriving SGI of its competitive advantage.

5.

Unrestricted disclosure would jeopardize the position of prominence of SGI in the world marketplace, and thereby give a market advantage to competitor in those countries in which SGI operates.

6.

SGIs capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.

The information is being transmitted to the USNRC in confidence and, under the provisions of 10 CFR 2.390, it is to be received in confidence by the USNRC. The information sought to be protected is not available in public sources and, to the best of our knowledge and belief, available information has not been previously employed in the same original manner or method.

The proprietary information is that associated with the pre-submittal meeting scheduled for January 10, 2022 with the NRC for the relief request to be submitted for the installation of the V-Wrap' CFRP Composite System at Calvert Cliffs Nuclear Power Plant (CCNPP), Units 1 and 2 and may be used only for that purpose. SGI owns or is permitted to use the proprietary information referenced in this Affidavit under agreements that include Exelon Generation Company, LLC maintaining the confidentiality of such information, as contemplated in this Affidavit.

Further this information has substantial commercial value as follows:

1.

The SGI plan to sell the use of this information to their customers for the purpose of installing the V-Wrap' Carbon Fiber Reinforced Polymer (CFRP) Composite System in safety related piping.

2.

That SGI can self-support and defense of the technology to their customers in the licensing process.

3.

The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by SGI.

4.

Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of SGI because it would enhance the ability of competitors to

provide similar licensing services for commercial power reactors without commensurate expenses.

5.

Public disclosure of the information would enable others to use the information to meet USNRC requirements for licensing documentation without purchasing the right to use the information.

6.

The development of the technology described in part by the proprietary information is the result of applying the results of many years of experience in an intensive effort by SGI and the expenditure of a considerable sum of money and resources. In order for competitors to duplicate this information, similar technical programs would have to be performed including a significant expenditure money and resources.

Further the deponent sayeth not.
