Supplement to the Submission of an Amendment Request for the NAC International MPC Amendment No. 9 Docket No. 72-1025 CAC/EPID Numbers 001028 / L-2023-LLA-0149 and 001028/ L-2023-LLA-0148

- 4. NRC Correspondence, Acceptance of NAC International Request for Amendment No. 9, and Revision to Amendment Nos. 6, 7, and 8, of the Certificate of Compliance No. 1025 for the NAC Multi-Purpose Canister System - Enterprise Project Identification Numbers L-2023-LLA-0149 and l-2023-LLA-0148, January 10, 2024 NAC International (NAC) hereby submits a supplement to our amendment request for the NAC-MPC CASK System. This supplement addresses the NRC identified structural observation in Reference 4. The observation identified that the Chapter 5.A shielding evaluations contained only reference to a minimum required concrete density of 145 pcf. It was determined upon further evaluation that the concrete cask shielding analysis applied a lid concrete density of 145 pcf rather than the design minimum density of 140 pcf. The ³Concrete Cask Lid +/- Concrete Specification Summary' (Table 1.A.2-6) and licensing drawing (630045-863 Revision 2) require minimum density of 140 pcf. Correcting this deficiency results in a negligible increase in dose rates. NAC is therefore, providing a new shielding calculation 63004500-5013 Revision 0 evaluating the impact to dose rates for the NAC-MPC LACBWR cask system. Additionally, we are submitting changed pages for the impacted Shielding Chapter (5.A).
Consistent with NAC administrative practice, this proposed SAR revision is numbered to uniquely identify the applicable changed pages. Revision bars mark the FSAR text changes on the Revision NAC-MPC 24A pages (Enclosure 3). Enclosure 1 is the list of NAC-MPC FSAR changes. Enclosure 2 contains the supporting calculation. The headers of the FSAR pages indicate Revision 24A and the submittal month and year on those pages that have changes and Revision bars mark the FSAR text changes.
ED20240024 U.S. Nuclear Regulatory Commission February 14, 2024 Page 2 of 2 Per Attachment 1 to this letter, NAC requests information in Enclosures 2 to be withheld from public disclosure per 10 CFR 2.390. In accordance with NAC¶s administrative practices, upon final acceptance of this application the 24A changed pages will be reformatted and incorporated into the initial revision of the NAC-MPC FSAR.
If you have any comments or questions, please contact me on my direct line at 678-328-1252.
Sincerely, Heath Baldner Director, Licensing Engineering Attachment +/- NAC International Affidavit Pursuant 10 CFR 2.390

ED20240024 Page 1 of 3 NAC INTERNATIONAL AFFIDAVIT PURSUANT TO 10 CFR 2.390 Doug Jacobs (Affiant), Vice President, Storage Projects, of NAC International Inc., hereinafter referred to as NAC, at 2 Sun Court, Suite 220, Peachtree Corners, Georgia 30092, being duly sworn, deposes and says that:
- 1. Affiant has reviewed the information described in Item 2 and is personally familiar with the trade secrets and privileged information contained therein, and is authorized to request its withholding.
- 2. The information to be withheld includes the following NAC Proprietary Information that is being provided in this submittal.
+/- NAC Supporting Calculation 63004500-5013 Revision 0 NAC is the owner of the information contained in the aforementioned pages/document, so they are considered NAC Proprietary Information.
- 3. NAC makes this application for withholding of proprietary information based upon the exemption from disclosure set forth in: the Freedom of Information Act (³FOIA'); 5 USC Sec. 552(b)(4) and the Trade Secrets Act; 18 USC Sec. 1905; and NRC Regulations 10 CFR Part 9.17(a)(4), 2.390(a)(4), and 2.390(b)(1) for ³trade secrets and commercial financial information obtained from a person, and privileged or confidential' (Exemption 4). The information for which exemption from disclosure is herein sought is all ³confidential commercial information,' and some portions may also qualify under the narrower definition of ³trade secret,' within the meanings assigned to those terms for purposes of FOIA Exemption 4.
- 4. Examples of categories of information that fit into the definition of proprietary information are:
- a. Information that discloses a process, method, or apparatus, including supporting data and analyses, where prevention of its use by competitors of NAC, without license from NAC, constitutes a competitive economic advantage over other companies.
- b. Information that, if used 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 of a similar product.
- c. Information that reveals cost or price information, production capacities, budget levels or commercial strategies of NAC, its customers, or its suppliers.
- d. Information that reveals aspects of past, present or future NAC customer-funded development plans and programs of potential commercial value to NAC.
- e. Information that discloses patentable subject matter for which it may be desirable to obtain patent protection.
The information that is sought to be withheld is considered to be proprietary for the reasons set forth in Items 4.a, 4.b, and 4.d.
ED20240024 Page 2 of 3 NAC INTERNATIONAL AFFIDAVIT PURSUANT TO 10 CFR 2.390 (continued)
- 5. The information to be withheld is being transmitted to the NRC in confidence.
- 6. The information sought to be withheld, including that compiled from many sources, is of a sort customarily held in confidence by NAC, and is, in fact, so held. This information has, to the best of my knowledge and belief, consistently been held in confidence by NAC. No public disclosure has been made, and it is not available in public sources. All disclosures to third parties, including any required transmittals to the NRC, have been made, or must be made, pursuant to regulatory provisions or proprietary agreements, which provide for maintenance of the information in confidence. Its initial designation as proprietary information and the subsequent steps taken to prevent its unauthorized disclosure are as set forth in Items 7 and 8 following.
- 7. Initial approval of proprietary treatment of a document/information is made by the Vice President, Engineering, the Project Manager, the Licensing Engineer, or the Director, Licensing +/- the persons most likely to know the value and sensitivity of the information in relation to industry knowledge.
Access to proprietary documents within NAC is limited via ³controlled distribution' to individuals on a ³need to know' basis. The procedure for external release of NAC proprietary documents typically requires the approval of the Project Manager based on a review of the documents for technical content, competitive effect and accuracy of the proprietary designation. Disclosures of proprietary documents outside of NAC are limited to regulatory agencies, customers and potential customers and their agents, suppliers, licensees and contractors with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements.
- 8. NAC has invested a significant amount of time and money in the research, development, engineering and analytical costs to develop the information that is sought to be withheld as proprietary. This information is considered to be proprietary because it contains detailed descriptions of analytical approaches, methodologies, technical data and/or evaluation results not available elsewhere. The precise value of the expertise required to develop the proprietary information is difficult to quantify, but it is clearly substantial.
Public disclosure of the information to be withheld is likely to cause substantial harm to the competitive position of NAC, as the owner of the information, and reduce or eliminate the availability of profit-making opportunities. The proprietary information is part of NAC¶s comprehensive spent fuel storage and transport technology base, and its commercial value extends beyond the original development cost to include the development of the expertise to determine and apply the appropriate evaluation process.
The value of this proprietary information and the competitive advantage that it provides to NAC would be lost if the information were disclosed to the public. Making such information available to other parties, including competitors, without their having to make similar investments of time, labor and money would provide competitors with an unfair advantage and deprive NAC of the opportunity to seek an adequate return on its large investment.
