A NAC I INTERNATIONAL December 8, 2017 U.S. Nuclear Regulatory Commission 11555 Rockville Pike Rockville, MD 20852-2738 Attn: Document Control Desk Atlanta Corporate Headquarters 3930 East Jones Bridge Road, Suite 200 Norcross, GA 30092 Phone 770-447-1144 Fax 770-447-1797 www.nacintl.com
Subject:
NAC's Request for a Revision to Certificate of Compliance (CoC) No. 9235 for the NAC-STC (Submittal 17D)
Docket No. 71-9235
References:
- 1. Model No. NAC-STC Package, U.S. Nuclear Regulatory Commission (NRC)
Certificate of Compliance (CoC) No. 9235, Revision 18, October 24, 2017
- 2. Safety Analysis Report (SAR) for the NAC Storage Transport Cask (NAC-STC), Revision 18, NAC International, March 2017 NAC International (NAC) hereby submits a request to revise the NAC-STC Certificate of Compliance (CoC) No. 9235, Revision 18 (Reference 1) to include adding an optional shield ring on the top forging which reduces the dose rate to below 200 mrem/hr. at the cask surface when shipping HBU (high burnup) or LBU (low burnup) fuel with reduced cool times, see SAR Sections 5.8 and 5.9 respectively. NAC is requesting this review to be treated separately from the existing NAC-STC amendment application before the NRC.
The 200 mrem/hr. limit is applicable to an exclusive use open transport configuration without crediting the personnel barrier. To achieve the 200 mrem/hr. limit with cool times shorter than currently approved by the NRC, SAR evaluations were conducted to allow a reduced minimum cool time when the shield ring configuration is used or to increase the cool time and limit the fuel hardware cobalt contents.
The proposed CoC changes include these new minimum cool time tables. To support these, existing figures and tables previously described in SAR Section 5.8 were reorganized to present the information in a more logical order. SAR Section 5.8 now contains evaluations of directly loaded HBU contents with and without the shield ring configuration, while Section 5.9 contains the evaluation of directly loaded LBU contents with the shield ring configuration using reduced cool times than what it is currently approved by the NRC.
Additionally, an analysis was performed to make the use of a ceramic fiber paper optional. The ceramic fiber paper is used to insulate the lead during the hypothetical fire accident, however new analyses show the lead temperatures can be maintained at a safe operating range without it.
To support the use of the thermal shunts at various sites additional holes have been added to interface with those site-specific fuel handling tools. The addition of the holes has a negligible effect on the structural evaluation of the thermal shunt or the overall cask systems shielding performance.

~I INTERNATIONAL U.S. Nuclear Regulatory Commission December 8, 2017 Page 2 of2 Consistent with NAC administrative practice, this proposed SAR revision is numbered to uniquely identify the applicable changed pages. Revision bars mark the SAR text changes on the Revision STC-17D pages (Enclosure 5) to the Reference 2 SAR pages. Enclosure 1 contains proprietary NAC calculations used to support the requested change. Enclosure 2 contains a summary of the changes to the SAR for Revision S TC-17D. Enclosure 3 contains a detailed list of drawing changes. The proposed changes to the certificate of compliance are contained in. As part of this submittal, NAC is including one hard copy of both the proprietary and non-proprietary versions. The proprietary version of this submittal is contained in a separate sealed envelope marked as "NAC Proprietary Information." An Affidavit pursuant to 10 CFR 2.390 is provided via Attachment 1 to this letter.
In accordance with NAC's administrative practices, upon final acceptance of this application, the STC-17D changed pages will be reformatted and incorporated into the next revision of the NAC-STC SAR.

~I INTERNATIONAL NAC INTERNATIONAL AFFIDAVIT PURSUANT TO 10 CFR 2.390 George Carver (Affiant), Vice President, Engineering and Licensing, of NAC International, hereinafter referred to as NAC, at 3930 East Jones Bridge Road, Norcross, 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-STC Proprietary Calculations o
423-3000, Revision 05 and data flash drive (1) o 423-5003, Revision 01 and data flash drive (1) o 423-5004, Revision 00 and data flash drive (1) o 30067-2010, Revision 00, Appendix D
- , List of Changes, Page 4
- , List of Drawing Changes, Page 2
- , NAC-STC SAR Rev. 17D, Proprietary Version 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 exem.ption from disclosure set forth in: the Freedom of Information Act ("FOIA"); 5 USC Sec. 552(b)(4) and the Trade Secrets Act; 18 USC Sec. 1905; and NRC Regulations 10 CFRPart 9.17(a)(4), 2.390(a)(4), and 2.390(b)(l) for "trade 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 "confidential commercial information," and some portions may also qualify under the narrower definition of "trade 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 supp01iing 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.
- 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 "controlled distribution" to individuals on a "need 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 ofNAC, 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 1
deprive NAC of the opportunity to seek an adequate return on its large investment.
