In Reference 1, NuScale Power, LLC (NuScale) submitted NRELAP5 files to support the NRC review of methodology topical reports associated with the Standard Design Approval Application. The specific topical reports are TR-0516-49416, Revision 4, "Non-Loss-of-Coolant Accident Analysis Methodology," TR-0516-49422, Revision 3, "Loss-of-Coolant Accident Evaluation Model, TR-124587, Revision 0, "Extended Passive Cooling and Reactivity Control Methodology," and TR-131981, Revision 1, "Methodology for the Determination of the Onset of Density Wave Oscillations (DWO)." To support review of the topical reports, NRC opened an audit (Reference 2). During the course of the audit, the NRC requested an updated version of the Reference 1 submittal for files affected by an NRELAP5 revision as described in audit questions A-NonLOCA.LTR-50, A.LOCA.LTR-51, A.LOCA.LTR-52, A-XPC.L TR-23, and A-DWO.LTR-127. NuScale provided the files in Reference 4. Subsequently, the NRC requested additional files. This letter provides a set of data discs of supplemental information to support NRC review of topical reports associated with the Standard Design Approval Application. The discs are labeled (Enclosure 1) and a file included on the discs provides a description of the supplemental content. Note that certain files previously provided by discs in the References 3 and 4 submittals are not included.

The discs contain information for NRC staff during technical review per Reference 2. The information on these discs is highly sensitive and considered NuScale Confidential, Proprietary Class 2, Export Controlled. This information also includes third party information which NuScale is obligated to keep confidential. Accordingly, NuScale requests that the discs be withheld in their entirety from public disclosure in accordance with the requirements of 10 CFR § 2.390. The enclosed affidavits (Enclosure 2 and 3) support this request. The discs also contain Export Controlled Information. This information must be protected from disclosure per the requirements of 10 CFR § 810.

This letter makes no regulatory commitments and no revisions to any existing regulatory commitments.

AFFIDAVIT of Mark W. Shaver I, Mark W. Shaver, state as follows:

(1)

I am the Director of Regulatory Affairs of NuScale Power, LLC (NuScale), and as such, I have been specifically delegated the function of reviewing the information described in this Affidavit that NuScale seeks to have withheld from public disclosure, and am authorized to apply for its withholding on behalf of NuScale (2)

I am knowledgeable of the criteria and procedures used by NuScale in designating information as a trade secret, privileged, or as confidential commercial or financial information. This request to withhold information from public disclosure is driven by one or more of the following:

(a)

The information requested to be withheld reveals distinguishing aspects of a process (or component, structure, tool, method, etc.) whose use by NuScale competitors, without a license from NuScale, would constitute a competitive economic disadvantage to NuScale.

(b)

The information requested to be withheld consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), and the application of the data secures a competitive economic advantage, as described more fully in paragraph 3 of this Affidavit.

(c)

Use by a competitor of the information requested to be withheld would reduce the competitor's expenditure of resources, or improve its competitive position, in the design, manufacture, shipment, installation, assurance of quality, or licensing of a similar product.

(d)

The information requested to be withheld reveals cost or price information, production capabilities, budget levels, or commercial strategies of NuScale.

(e)

The information requested to be withheld consists of patentable ideas.

(3)

Public disclosure of the information sought to be withheld is likely to cause substantial harm to NuScale's competitive position and foreclose or reduce the availability of profit-making opportunities. The accompanying information contained on the data discs reveals distinguishing aspects about the method by which NuScale performs transient analyses.

NuScale has performed significant research and evaluation to develop a basis for this method and has invested significant resources, including the expenditure of a considerable sum of money.

The precise financial value of the information is difficult to quantify, but it is a key element of the design basis for a NuScale plant and, therefore, has substantial value to NuScale.

If the information were disclosed to the public, NuScale's competitors would have access to the information without purchasing the right to use it or having been required to undertake a similar expenditure of resources. Such disclosure would constitute a misappropriation of NuScale's intellectual property, and would deprive NuScale of the opportunity to exercise its competitive advantage to seek an adequate return on its investment.

(4)

The information sought to be withheld is contained on the subject data discs transmitted with the letter entitled "NuScale Power, LLC Submittal of Supplemental Information in Support of NRC Review of NuScale Topical Reports Associated with the Standard Design Approval Application."

The data discs bear the designation "Proprietary" since the information they contain is considered by NuScale to be proprietary.

AF-176113 Page 1 of 2

(5)

The basis for proposing that the information be withheld is that NuScale treats the information as a trade secret, privileged, or as confidential commercial or financial information. NuScale relies upon the exemption from disclosure set forth in the Freedom of Information Act ("FOIA"), 5 USC § 552(b)(4), as well as exemptions applicable to the NRC under 10 CFR §§ 2.390(a)(4) and 9.17(a)(4).

(6)

Pursuant to the provIsIons set forth in 10 CFR § 2.390(b)(4), the following is provided for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld:

(a)

The information sought to be withheld is owned and has been held in confidence by NuScale (b)

The information is of a sort customarily held in confidence by NuScale and, to the best of my knowledge and belief, consistently has been held in confidence by NuScale. The procedure for approval of external release of such information typically requires review by the staff manager, project manager, chief technology officer or other equivalent authority, or the manager of the cognizant marketing function (or his delegate), for technical content, competitive effect, and determination of the accuracy of the proprietary designation.

Disclosures outside NuScale are limited to regulatory bodies, customers and potential customers and their agents, suppliers, licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or contractual agreements to maintain confidentiality.

(c)

The information is being transmitted to and received by the NRC in confidence.

(d)

No public disclosure of the information has been made, and it is not available in public sources. All disclosures to third parties, including any required transmittals to NRC, have been made, or must be made, pursuant to regulatory provisions or contractual agreements that provide for maintenance of the information in confidence.

(e)

Public disclosure of the information is likely to cause substantial harm to the competitive position of NuScale, taking into account the value of the information to NuScale, the amount of effort and money expended by NuScale in developing the information, and the difficulty others would have in acquiring or duplicating the information. The information sought to be withheld is part of NuScale's technology that provides Nu Scale with a competitive advantage over other firms in the industry. NuScale has invested significant human and financial capital in developing this technology and NuScale believes it would be difficult for others to duplicate the technology without access to the information sought to be withheld.

I declare under penalty of perjury that the foregoing is true and correct. Executed on December 02, 2024.

(a)

The information reveals details of Framatome's research and development plans and programs or their results.

(b)

Use of the information by a competitor would permit the competitor to significantly reduce its expenditures, in time or resources, to design, produce, or market a similar product or service.

(c)

The information includes test data or analytical techniques concerning a process, methodology, or component, the application of which results in a competitive advantage for Framatome.

(d)

The information reveals certain distinguishing aspects of a process, methodology, or component, the exclusive use of which provides a competitive advantage for Framatome in product optimization or marketability.

(e)

The information is vital to a competitive advantage held by Framatome, would be helpful to competitors to Framatome, and would likely cause substantial harm to the competitive position of Framatome.

The information in this Document is considered proprietary for the reasons set forth in paragraph 6(c), 6(d) and 6(e) above.

7.

In accordance with Framatome's policies governing the protection and control of information, proprietary information contained in this Document has been made available, on a limited basis, to others outside Framatome only as required and under suitable agreement providing for nondisclosure and limited use of the information.

Framatome policy requires that proprietary information be kept in a secured file or area and distributed on a need-to-know basis.

9.

The foregoing statements are true and correct to the best of my knowledge, information, and belief.

I declare under penalty of perjury that the foregoing is true and correct.
