GE-Hitachi Nuclear Energy Americas LLC AFFIDAVIT I, Kent E. Halac, state as follows:

(1) I am a Senior Engineer, GE-Hitachi Nuclear Energy Americas LLC (GEH), and have been delegated the function 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 GEH proprietary report 007N5355P, Fermi 2 Power Plant Core Plate Bolt BWRVIP-25 Appendix I Evaluation, Revision 0, dated January 13, 2023. GEH proprietary information in 007N5355P Revision 1 is identified by a dotted underline inside double square brackets. ((This sentence is an example.{3})). GEH proprietary information in figures and large objects is identified by double square brackets before and after the object. In each case, the superscript notation {3}

refers to Paragraph (3) of this affidavit, which provides the basis for the proprietary determination.

(3) In making this application for withholding of proprietary information of which it is the owner or licensee, GEH relies upon the exemption from disclosure set forth in the Freedom of Information Act (FOIA), 5 U.S.C. §552(b)(4), and the Trade Secrets Act, 18 U.S.C.

§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 qualifies 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, 975 F.2d 871 (D.C. Cir. 1992), and Public Citizen Health Research Group v. FDA, 704 F.2d 1280 (D.C. Cir. 1983).

(4) The information sought to be withheld is considered to be proprietary for the reasons set forth in paragraphs (4)a and (4)b. Some 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 GEH's competitors without a license from GEH constitutes a competitive economic advantage over other companies;

b. Information that, if used by a competitor, would reduce its expenditure of resources or improve its competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing of a similar product;

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

d. Information that discloses trade secret or potentially patentable subject matter for which it may be desirable to obtain patent protection.

007N5355P Revision 0 Affidavit Page 1 of 3

GE-Hitachi Nuclear Energy Americas LLC (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 GEH, 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 GEH, not been disclosed publicly, and not been made 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 for proprietary or confidentiality agreements or both that provide for maintaining the information in confidence. The initial designation of this information as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in the following paragraphs (6) and (7).

(6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, who is the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge, or who is the person most likely to be subject to the terms under which it was licensed to GEH.

(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 for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside GEH 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 and/or confidentiality agreements.

(8) The information identified in paragraph (2) is classified as proprietary because it contains the detailed GEH methodology for pressure-temperature curve analysis for the GEH Boiling Water Reactor (BWR). These methods, techniques, and data along with their application to the design, modification, and analyses associated with the pressure-temperature curves were achieved at a significant cost to GEH.

The development of the evaluation processes along with the interpretation and application of the analytical results is derived from the extensive experience databases that constitute a major GEH asset.

(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GEH's competitive position and foreclose or reduce the availability of profit-making opportunities. The information is part of GEH'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.

007N5355P Revision 0 Affidavit Page 2 of 3

GE-Hitachi Nuclear Energy Americas LLC The research, development, engineering, analytical and NRC review costs comprise a substantial investment of time and money by GEH. 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. GEH's competitive advantage will be lost if its competitors are able to use the results of the GEH 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 GEH would be lost if the information were disclosed to the public. Making such information available to competitors without there having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall and deprive GEH 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 13th day of January 2023.

Subject:

Request for Withholding of the Following Proprietary Information Included In:

Fermi 2 Power Plant Core Plate Bolt BWRVIP-25 Appendix I Evaluation GE Hitachi Nuclear Energy 007N5355, Revision OJanuary 2023 I, Steven Swilley, being duly sworn, depose and state as follows:

I am the Vice President and Deputy Chief Nuclear Officer at Electric Power Research Institute, Inc., whose principal office is located at 3420 Hillview Avenue, Palo Alto, California ("EPRI"), and I have been specifically delegated responsibility for the above-listed Report which contains EPRI Proprietary Information that is sought under this Affidavit to be withheld "Proprietary Information". I am authorized to apply to the U.S. Nuclear Regulatory Commission C'NRC")

for the withholding of the Proprietary information on behalf of EPRI.

EPRI Proprietary Information is identified in the above referenced report with text inside double brackets.

Examples of such identification is as follows:

((This sentence is an example{El))

Tables containing EPRI Proprietary Information are identified with double brackets before and after the object.

In each case the superscript notation [El refers to this affidavit and all the bases included below, which provide the reasons for the proprietary determination.

EPRI requests that the Proprietary Information be withheld from the public on the following bases:

Withholding Based Upon Privileged and Confidential Trade Secrets or Commercial or Financial Information (see e.g. 10 C.F.R. §2.390(a){4)):

a. The Proprietary Information is owned by EPRI and has been held in confidence by EPRI. All entities accepting copies of the Proprietary Information do so subject to written agreements imposing an obligation upon the recipient to maintain the confidentiality of the Proprietary Information. The Proprietary Information is disclosed only to parties who agree, in writing, to preserve the confidentiality thereof.

b. EPRI considers the Proprietary Information contained therein to constitute trade secrets of EPRI. As such, EPRI holds the information in confidence, and disclosure thereof is strictly limited to individuals and entities who have agreed, in writing, to maintain the confidentiality of the Information. EPRI made a substantial economic investment to develop the Proprietary Information, and, by prohibiting public disclosure, EPRI derives an economic benefit in the form of licensing royalties and other additional fees from the confidential nature of the Proprietary Information. If the Proprietary Information were publicly available to consultants and/or other businesses providing services in the electric and/or nuclear power industry, they would be able to use the Proprietary Information for their own commercial benefit

and profit and without expending substantial economic resources required of EPRI to develop the Proprietary information.

c. EPRl's classification of the Proprietary Information as trade secrets is justified by the Uniform Trade Secrets Act. which California adopted in 1984 and a version of which has been adopted by over forty states. The California Uniform Trade Secrets Act, California Civil Code §§3426 - 3426.11, defines a "trade secret" as follows:

'Trade secret' means information, including a formula, pattern, compilation, program device, method, technique, or process, that:

(1) Derives independent economic value, actual or potential, from not being generally known to the public or to other persons who can obtain economic value from its disclosure or use; and

2) Is the subject of efforts that are reasonable under the circumstances to maintain its secrecy."

d. The Proprietary Information contained therein are not generally known or available to the public. EPRI developed the Information only after making a determination that the Proprietary Information was not available from public sources. EPRI made a substantial investment of both money and employee hours in the development of the Proprietary Information. EPRI was required to devote these resources and effort to derive the Proprietary Information.

As a result of such effort and cost, both in terms of dollars spent and dedicated employee time, the Proprietar1 Information is highly valuable to EPRI.

e. A public disclosure of the Proprietary Information would be highly likely to cause substantial harm to EPRl's competitive position and the ability of EPRI to license the Proprietary Information both domestically and internationally.

The Proprietary Information and Report can only be acquired and/or duplicated by others using an equivalent investment of time and effort.

I have read the foregoing, and the matters stated herein are true and correct to the best of my knowledge, information, and belief. I make this affidavit under penalty of perjury under the laws of the United States of America and the laws of the State of North Carolina.

Executed at 1300 W WT Harris Blvd, Charlotte, NC being the premises and place of business of Electric Power Research Institute, Inc.

1.0 INTRODUCTION

Fermi 2 core plate bolts are evaluated for eliminating or reducing the inspection requirements using the methodology in the BWRVIP-25 Appendix I (Reference 1). The current licensed operating conditions analyzed in the Thermal Power Optimization Safety Analysis Report (Reference 2) are applied with GNF3 fuel and 24 month fuel cycle in the evaluation. The fluence for 60 years of plant life is considered in the analysis. Consistent with GNF3 RPV internals evaluations, Safety Communication (SC) 11-07 (Reference 3) is not considered for the core plate bolt evaluation.

5

007N5355NP Revision 0 Non-Proprietary Information 2.0 BWRVIP-25 APPENDIX I METHODOLOGY FOR CORE PLATE BOLTS The analysis in BWRVIP-25 Appendix I (Reference 1) was based on the Service Level D (Faulted condition) loading and allowable limits because of the dominating effect of horizontal SSE (a Faulted condition seismic load) on the displacement and ASME Code stress limits. In BWRVIP-25 Appendix I analysis for each category of core plate/bolt design, several horizontal loads were evaluated to determine the corresponding required number of bolts with fixed vertical loads, which are intended to be bounding. These fixed vertical loads are listed in Table 8-3 of BWRVIP-25 Appendix I. In order to apply the results in BWRVIP-25 Appendix I to a specific plant, the plant specific vertical loads and accumulated neutron fluence need to be bounded by those in Table 8-3. Otherwise, the BWRVIP-25 Appendix I results should not be used and additional plant-specific analysis for the core plate bolts should be considered. In addition, the conditions of SC 11-05 (Reference 5) are met.

6

007N5355NP Revision 0 Non-Proprietary Information 3.0 FERMI 2 CORE PLATE BOLT EVALUATION 3.1 Fermi 2 Core Plate Design and Load Combination Fermi 2 is a BWR/4 Mark I containment plant. Fermi 2 core plate design is classified as Category 1 with 34 core plate bolts as listed in BWRVIP-25 Appendix I (Reference 1). Fermi 2 is one of the Mark I Exception plants (Reference 4) which is not a New Loads or Old Loads plant. The applicable dynamic loads for the core plate include Annulus Pressurization (AP) and Fuel Lift in addition to the seismic. The limiting load combination for Fermi 2 core plate in Service Level D is (Table 13-5 of Reference 4) as follows.

(( ))

The (( )) are vertical loads. SSE has both vertical and horizontal components.

AP is a horizontal load. Thermal stresses of core plate are insignificant because there are no thermal gradients on the core plate. Furthermore, it is not required to include the thermal stress in Faulted condition for the ASME code evaluation. Therefore, thermal stresses are not included in BWRVIP-25 Appendix I and design basis calculations in Faulted condition.

3.2 SC 11-05 Considerations BWRVIP-25 Appendix I set the acceptable core plate horizontal displacement limit to ((

)) inch with the considerations of conditions identified in SC 11-05 (Reference 5). This displacement limit accounts for additional control-blade-to-fuel-channel friction due to the possibility of existing channel bow, monitored by SC 11-05. For Fermi 2, one of the plants that SC 11-05 is applicable, the conditions of SC 11-05 are met for the core plate bolt evaluation because SC 11-05 has been considered in the displacement limit and the channel bow is monitored.

3.3 Fermi 2 Core Plate Vertical Loads The vertical loads are summarized in the following table. Fermi 2 specific vertical loads are found to be within the analyzed conditions of BWRVIP-25 Appendix I. The Fermi 2 fluence in the table is the maximum value at the top of the core plate bolts among all azimuthal locations. The Fermi 2 fluence and core plate bolt torque also meet the analyzed limits. Therefore, the Preload Final Multiplier of (( )) in Table 6-1 of BWRVIP-25 Appendix I applies to Fermi 2.

007N5355NP Revision 0 Non-Proprietary Information 3.4 Fermi 2 Core Plate Horizontal Load and Required Number of Core Plate Bolts The combined horizontal load on Fermi 2 core plate is (( )) kips. Per the Table 9-2 of BWRVIP-25 Appendix I, (( )) bolts are needed if the horizontal load is (( )) kips. The load of 455 kips is the minimum combined horizontal load analyzed in BWRVIP-25 Appendix I for category 1 core plate plants with FLL in their design bases. With (( )) kips of horizontal load for Fermi 2 core plate, the number of core plate bolts needed are less than (( ))

out of the total of 34 bolts. However, the exact number of bolts needed cannot be determined because interpolation or extrapolation of the results is not allowed as stated in Section 9 of BWRVIP-25 Appendix I (Reference 1). There is considerable margin in terms of number of core plate bolts needed versus available number of bolts for the horizontal load of (( )) kips.

Following the Figure 9-9 Applicability Flow Chart in BWRVIP-25 Appendix I, this evaluation justifies no additional inspections of core plate bolts for Fermi 2.

4.0 CONCLUSION

S Fermi 2 core plate design is category 1 with 34 core plate bolts as analyzed in BWRVIP-25 Appendix I with FLL considered in the design basis.

• The loads and conditions for Fermi 2 core plate with licensed/analyzed operating conditions, including GNF3 fuel and 24 month fuel cycle, are bounded by those analyzed in BWRVIP-25 Appendix I.

• Therefore, the results of BWRVIP-25 Appendix I can be applied to Fermi 2 core plate bolts.

• The number of core plate bolts needed for Fermi 2 are less than (( )) out of total of 34 bolts.

• Following the Figure 9-9 Applicability Flow Chart in BWRVIP-25 Appendix I, this evaluation justifies no additional inspections of core plate bolts for Fermi 2.
