ENCLOSURE 3 KGO-ENO-LDl-18-120 Affidavit for Enclosure 1 _, . ~ I .. --'"' ............ .~

Global Nuclear Fuel- Americas AFFIDAVIT I, Lisa K. Schichlein, state as follows: (1) I am a Senior Project Manager, NPP/Services Licensing, Regulatory Affairs, Global Nuclear Fuel - Americas, LLC (" GNF-A"), and have been delegated the fUllction of reviewing the information described in paragraph (2) which is sought to be withheld, and have been authorized to apply for its withholding. (2) The information sought to be withheld is contained in Enclosure I of GNF letter KGO-ENO-LDI-18-120, Kimberly O' Connor (GNF) to Don Lomax (Entergy), entitled "Revised Proprietary Identification for GNF Pre-Submittal Meeting Presentation on River Bend Station Spent Fuel Pool Criticality Analysis of Boraflex Storage Racks with NETCO-SNAP-IN Rack Inserts," dated September 13, 2018. The proprietary information in Enclosure 1, which is entitled "River Bend Station Spent Fuel Pool Criticality Analysis of Boraflex torage Racks with NETCO-SNAP-IN Rack Inserts", is identified by a dotted underline inside double square brackets. [[Ib.i~...~~;mt~n£Y...i ... Jm.. ~~w:np.l~ . ~~!.J] GNF proprietary information in figures and large objects is identified with double square brackets before and after the object. In each ca e, the superscript notation {3} refers to Paragraph (3) of this affidavit, which provides the ba is for the proprietary determination . (3) In making this application for withholding of proprietary information of which it is the owner or licensee, GNF-A 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 10 CFR 9.17(a)(4), and 2.390(a)(4) for "trade secrets" (Exemption 4). The material for which exemption from disclosure is here sought 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, 975F2d871 (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2d 1280 (DC Cir. 1983). (4) orne examples of categories of information which fit into the definition of proprietary information are:

a. Information that discloses a proce , method, or apparatus, including supporting data and analyses, where prevention of its u e by GNF-A's competitors without license from GNF -A 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; KGO-ENO-LDl-18-120 Affidavit Page 1 of3

c. Information which reveals aspects of past, present, or future GNF-A customer-funded development plans and programs, resulting in potential products to GNF-A;

d. 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 paragraphs (4)a. and (4)b. above. (5) To address 10 CFR 2.390 (b) (4), the information sought to be withheld is being submitted to NRC in confidence. The information is of a sort customarily held in confidence by GNF-A, 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 GNF-A, no public disclosure has been made, and it is not available in public sources. All disclosures to third parties including any required tran mittals to 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 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, or subject to the terms under which it was licensed to GNF-A . (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 delegate), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Di closures outside GNF-A are limited to regulatory bodies, customers, and potential customer , 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 identified in paragraph (2), above, is classified as proprietary because it contains detail s of GNF-A ' s criticality analysis methodology . The development of this methodology, along with the testing, development and approval was achieved at a significant cost to GNF-A or its licensor. The development of the criticality analysis methodology along with the interpretation and application of the analytical results is derived from the extensive experience database that constitutes a major GNF-A asset. KGO-ENO-LDl-18-120 Affidavit Page 2 of3

(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GNF-A's competitive position and foreclose or reduce the avai lability of profit-making opportunities. The information is part of GNF-A's comprehensive BWR safety and 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. In addition, the technology base includes the value derived from providing analyses done with NRC-approved methods. The research, development, engineering, analytical , and NRC review costs comprise a substantial investment of time and money by GNF-A. 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. GNF-A's competitive advantage will be lost if its competitors are able to u e the results of the GNF-A 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 GNF-A would be lost if the information were disclosed to the public. Making sLlch 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 GNF-A of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing and obtaining these very valuable analytical tools. I declare under penalty of perjury that the foregoing is true and correct. Executed on this lIth day of September 2018 .
