(1)Letter from Patrick R. Simpson (Exelon Generation Company, LLC) to U.S. NRC, "License Amendment Request Regarding Spent Fuel Storage Pool Criticality Methodology and Proposed Change to Technical Specification 4.3.1, 'Criticality'," dated December 30, 2014 (2) Letter from U.S. NRC to Bryan Hanson (Exelon Generation Company, LLC),"Dresden Nuclear Power Station, Units 2 and 3 -Non-acceptance of Requested Licensing Action -License Amendment Request Regarding Spent Fuel Storage Pool Criticality Methodology and Proposed Change to Technical Specification 4.3.1, 'Criticality,' (TAC Nos. MF5734 and MF5735)," dated April 24, 2015 (3) Letter from David M. Gullott (Exelon Generation Company, LLC) to U. S.NRC, "Supplemental Information Regarding License Amendment Request Regarding Spent Fuel Pool Criticality Methodology and Proposed Change to Technical Specification 4.3.1, 'Criticality'," dated May 8, 2015 In the referenced letter, Exelon Generation Company, LLC (EGC) requested an amendment to Renewed Facility Operating License Nos. DPR-19 and DPR-25 for Dresden Nuclear Power Station (DNPS), Units 2 and 3, respectively.
Specifically, EGC is utilizing a new Criticality Safety Analysis (CSA) methodology for performing the criticality safety evaluation for legacy fuel types in addition to the new ATRIUM 10XM fuel design in the spent fuel pool (SFP). In addition, EGC is proposing a change to the DNPS Technical Specification (TS) 4.3.1, "Criticality," in Attachment 1 transmitted herewith contain Proprietary Information.

July 30, 2015 U. S. Nuclear Regulatory Commission Page 2 support of the new GSA. EGG proposes to add a new TS 4.3.1.1 .c that will require an in-rack k-infinity limit for the fuel assemblies that are allowed to be stored in the DNPS Units 2 and 3 SEP storage racks.In Reference 2, the NRC provided the results of the acceptance review of the license amendment request. The NRC concluded that supplemental information was needed to enable the NRC to make an independent assessment regarding the acceptability of the proposed amendment request in terms of regulatory requirements and the protection of public health and safety and the environment.
EGC provided the requested information in Reference 3.EGG and the NRC participated in a conference call on April 7, 2015 to discuss the NRC Staff request for supplemental information in support of their acceptance review. During this conference call, the NRC indicated that their review of Reference 1 identified a number of deficiencies with the proprietary markings in the Holtec International licensing report for the criticality analysis of the DNPS Units 2 and 3 Spent Fuel Pool provided as Attachment 3 to Reference
- 1. The NRC also noted deficiencies with the Affidavit submitted in support of withholding the proprietary Holtec International documents from public disclosure.
Subsequent to the April 7, 2015 conference call, Holtec International revised the proprietary report to address the NRC identified deficiencies.
EGC is supplementing Reference 1 to address the NRC identified proprietary deficiencies by providing the revised report and affidavit with this letter.The following attachments are included in support of this proposed change: Attachment 1: Holtec International Report No. HI-21461 53, Revision 2, "Licensing Report for the Criticality Analysis of the Dresden Unit 2 and 3 SEP for ATRIUM 10OXM Fuel Design" (Proprietary Version)Attachment 2: Holtec International Affidavit Requesting Proprietary Report be Withheld from Public Disclosure Attachment 3: Holtec International Report No. HI-21461 53, Revision 2, "Licensing Report for the Criticality Analysis of the Dresden Unit 2 and 3 SEP for ATRIUM 10XM Fuel Design" (Non-Proprietary Version)Attachments 1, 2, and 3 to this letter supersede in full Attachments 3, 5, and 6 of Reference 1, respectively.
EGG has reviewed the information supporting a finding of no significant hazards consideration, and the environmental consideration, that were previously provided to the NRC in Attachment 1 of Reference
- 1. The additional information provided in this submittal does not affect the bases for concluding that the proposed license amendment does not involve a significant hazards consideration.
In addition, the additional information provided in this submittal does not affect the bases for concluding that neither an environmental impact statement nor an environmental assessment needs to be prepared in connection with the proposed amendment.
Attachment I transmitted herewith contain Proprietary Information.

ATTACHMENT 2 Holtec International Affidavit Requesting Proprietary Report be Withheld from Public Disclosure Center, 555 Lincoln Drive West, Marlton, NJ 08053 H O LTE C Telephone (856) 797-0900 I NT ER NAT ION AL Fax (856) 797-0909 Holtec International Document I1D 2393-AFFI-01 AFFIDAVIT PURSUANT TO 10 CFR 2.399 I, Debabrata (Debu) Mitra Majumndar (Corporate Director of Engineering Analyses, Holtec International), being duly sworn, depose and state as follows: (1) I have reviewed the information described in paragraph (2) which is sought to be withheld, and am authorized to apply for its withholding.
(2) The information sought to be withheld is information provided in the following reports.a. Holtec International Report No. [11-2146153, "Licensing Report for the Criticality Analysis of the Dresden Unit 2 and 3 SFP for ATRIUM 10OXM Fuel Design", Revision 2 (Proprietary Version).b. Holtec International Report No. HI-2104790, Revision 1, "Nuclear Group Computer Code Benchmark Calculations" (Proprietary).
These reports contain Holtec proprietary information.
(3) In making this application for withholding of proprietary information of which it is the owner, Holtec International relies upon the exemption 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 10CFR Part 9. 17(a)(4), 2.390(a)(4), and 2.390(b)(1) for "trade secrets and commercial or financial information obtained from a person and privileged or confidential" (Exemption 4). The material for which exemption from disclosure is here sought is all "confidential commercial information", and some portions also qualify under the narrower definition of "trade secret", within the meanings assigned to those terms for purposes of FOIA Exemption 4 in, respectively, Critical Mass Energy Project v. Nuclear Regulatory Commission:
975F2d87l (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2d1280 (D)C Cir. 1983).1 of 5 Holtee International Document ID 2393-AFFI-O1 AFFIDAVIT PURSUANT TO 10 CER 2.390 (4) Some examples of categories of information which 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 Holtec's competitors without license from Holtec International constitutes a competitive economic advantage over other companies;
- b. Information which, if used 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 of a similar product.c. Information which reveals cost or price information, production, capacities, budget levels, or commercial strategies of Holtec International, its customers, or its suppliers;
- d. Information which reveals aspects of past, present, or future Holtec International customer-funded development plans and programs of potential commercial value to Holtec International;
- e. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.
The information sought to be withheld is considered to be proprietary for the reasons set forth in paragraph 4.b, above.(5) The information sought to be withheld is being submitted to the NRC in confidence.
The information (including that compiled from many sources) is of a sort customarily held in confidence by Holtec International, and is in fact so held. The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by Holtec International.
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 2 of 5 Holtec International Document ID 2393-AFFI-Ol AFFIDAVIT PURSUANT TO 10 CFR 2.390 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 paragraphs (6) and (7) following.
(6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge.
Access to such documents within Iloltec International is limited on a "need to know" basis.(7) The procedure for approval of external release of such a document typically requires review by the staff manager, project manager, principal scientist or other equivalent authority, by the manager of the cognizant marketing function (or his designee), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation.
Disclosures outside IHoltec International are limited to regulatory bodies, customers, and potential customers, and their agents, suppliers, and licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements.
(8) The information classified as proprietary was developed and compiled by Holtec International at a significant cost to Holtec International.
This information is classified as proprietary because it contains detailed descriptions of analytical approaches and methodologies not available elsewhere.
This information would provide other parties, including competitors, with information from Holtec International's technical database and the results of evaluations performed by Holtec International.
A substantial effort has been expended by Floltee International to develop this information.
Release of this information would improve a competitor's position because it would enable Holtec's competitor to copy our technology and offer it for sale in competition with our company, causing us financial injury.3 of 5 Holtec International Document 11D 2393-AFFI-O1 AFFIDAVIT PURSUANT TO 10 CFR 2.390 (9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to Holtec International's competitive position and foreclose or reduce the availability of profit-making opportunities.
The information is part of Holtec International's comprehensive spent fuel storage technology base, and its commercial value extends beyond the original development cost. The value of the technology base goes beyond the extensive physical database and analytical methodology, and includes development of the expertise to determine and apply the appropriate evaluation process.The research, development, engineering, and analytical costs comprise a substantial investment of time and money by Holtec International.
The precise value of the expertise to devise an evaluation process and apply the correct analytical methodology is difficult to quantify, but it clearly is substantial.
Holtec International's competitive advantage will be lost if its competitors are able to use the results of the Holtec International experience to normalize or verify their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions.
The value of this information to Holtec International would be lost if the information were disclosed to the public. Making such information available to competitors without their having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall, and deprive Holtec International of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing these very valuable analytical tools.4 of 5 Holtec International Document ID 2393-AFFI-Ol AFFIDAVIT PURSUANT TO 10 CFR 2.390 STATE OF N~EW JERSEY )) ss: COUNTY OF BURLINGTON
